The transmission line of the fire detector should choose different colors of insulated wires or cables, and the "ten" line should be red. The "one" wire should be blue, the color of the same purpose wire in the same project should be the same, and the terminal should be labeled. The transmission line has a great influence on the reliability of the whole system, and expands with the increase of the system. Now according to the different types of detectors, the electrical circuit is divided into: multi-wire system, bus system, and two-wire chain connection method. (1) The number of multi-wire transmission lines is large, the cost is high, the construction is difficult to calculate the failure rate is high, and it is a knockout commodity; (2) The number of bus transmission lines is sharply reduced, the cost is low, and the calculated failure rate is greatly reduced. The bus system is divided into two, three and four buses. The two-bus transmission line is better than the three-four-bus transmission line, which is the current mainstream transmission line. The reliability of the system which integrates the linkage control and alarm is the highest by using the two-bus method. Most of the bus transmission lines use the tree wiring method (that is, the generally referred to as the parallel wiring method), and the advantages are simple, convenient, and easy to expand; But its defects are also clear: once the bus circuit appears short or open, the entire circuit fails. Although some manufacturers now have introduced the method of adding isolators in the loop in order to improve the availability of goods, this is also a last resort. Because this makes the whole system complicated, not easy to use, maintenance, but also add the cost and danger of equipment. (3) The chain connection method is one of the two wire system methods, the main characteristics are as follows: first, the loop with less line; Second, it can identify the condition of each detector at that time (normal, fault or fire alarm level condition); Third, the loop can be connected into a ring type. Therefore, when the circuit presents a short circuit or open circuit fault, the system can ensure that other detectors in the circuit work normally through two-way power supply, and quickly find the fault point, that is, the loop has self-maintenance ability. With the in-depth development of electronic and mechanical processing skills, more advanced automatic fire alarm systems have been developed, such as high-grade intelligent automatic fire alarm systems that use artificial neural networks to process fire signals; The automatic fire alarm system with multi-level computer hierarchical management method is selected, that is, the management of disaster prevention, power and air conditioning in a building is combined in a sound computer management system, and disaster prevention (mainly automatic fire protection system), power and air conditioning are managed and controlled by a special microcomputer; Choose computer fire alarm voice, all early warning, alarm use voice to inform you how to deal with the fire, with the fire scene of various data parameters automatically recorded to help you analyze the cause of the fire

Ten important questions about the future of the Class I Certified Fire Engineer Certificate Question 1: What is the passing rate of Grade I certified fire Engineer in 2015? A: The official did not release the pass rate, from the personnel examination network around the announcement of the exam qualification list can be seen that the pass rate is extremely low. The formula for calculating the passing rate is different, and there are still a large part of the candidates who failed to pass the examination, did not pay the fee, abandoned the examination and so on. If the number of qualified people divided by the total number of applicants, the pass rate of various places is at most 115÷23733≈5‰. The official website of The State Council released news on December 19, 2015, a total of more than 440,000 people registered for the national examination, according to the fire station on January 12, 2016, the mobilization meeting site, the country to participate in the "case analysis" subject exam candidates nearly 240,000, which can be calculated that the national pass rate is about 1%. Question 2: How many qualified Grade I registered fire engineers are there in 2015? A: The official data has not yet been released, according to the pass rate, the number of registered fire engineers in 2015 May be between 3000-5000. Question 3: Which units can a certified fire engineer register with? A: Registered fire engineers should be registered in fire technical service institutions or fire safety key units, to carry out fire safety technology activities consistent with the business scope of the institution or unit and my qualification level. Q4: What are the jobs of certified fire engineers? A: Registered fire engineers in the fire technical service institutions engaged in fire protection facilities testing and maintenance, fire safety monitoring and inspection, fire technical consultation and fire safety assessment, fire accident technical analysis and other fire safety technical work; In the key units of fire safety mainly engaged in fire safety management. Q5: How many registered fire engineers are required by the fire technical service agency? Level I test and maintenance qualification: more than 10 people, including at least 6 registered fire engineers; Secondary testing and maintenance qualification: more than 6 people, of which at least 3 registered fire engineers; Secondary test maintenance qualification: more than 1 person; Level I safety assessment qualification: more than 12 people, including at least 8 level I registered fire engineers; Secondary safety assessment qualification: more than 8 people, including at least 4 registered fire engineers; Obtain the qualification of test maintenance and safety assessment at the same time: 80% of the total number of people required for the two qualifications, and not less than the number of people for any single qualification condition. Question 6: How many fire technical service agencies in China have obtained provisional qualification? Answer: Because some provinces have not publicly obtained the list of temporary fire technical service qualifications in the province, the Ministry of Public Security fire bureau has not disclosed the full list, 114 network only lists the number of temporary fire technical service agencies published in some provinces as a reference (the following data are from the official website of the provinces or relevant official documents), due to too many provinces, not a list. Henan: 20 first-level testing and maintenance qualifications (18 in Zhengzhou, 2 in Luoyang), 30 second-level testing and maintenance qualifications (24 in Zhengzhou, the remaining 6 in Luoyang, Kaifeng, Nanyang and other cities), 14 second-level safety assessment qualifications (10 in Zhengzhou, the remaining 4 in Luoyang, Pingdingshan, Xinyang and other cities); Shandong: 66 first-level testing and maintenance qualifications (most distributed in Jinan, Qingdao, a few distributed in Yantai, Zibo, Weifang and other cities), 156 second-level testing and maintenance qualifications (number distributed in Jinan, Qingdao, a few distributed in Yantai, Zibo, Weifang and other cities), 34 second-level assessment qualifications (most cities have); Note: Shandong Province alone needs more than 1,000 registered fire engineers for the transition of temporary qualifications. Tianjin: 21 first-level testing and maintenance qualifications, 20 second-level testing and maintenance qualifications, 1 first-level safety assessment qualification, 5 second-level safety assessment qualification; Inner Mongolia: 3 first-level test and maintenance qualifications (all located in Hohhot), 13 second-level test and maintenance qualifications (9 in Hohhot, one in Hulunbuir, Tongliao, Xilinhot and Ordos), 1 safety assessment qualification (located in Hohhot); Shaanxi: 9 first-level testing and maintenance qualifications (8 in Xi 'an, 1 in Xianyang), 8 second-level testing and maintenance qualifications (all in Xi 'an); Sichuan: 23 first-level testing and maintenance qualifications (21 in Chengdu, Liangshan and Leshan each), 30 second-level testing and maintenance qualifications (23 in Chengdu, the remaining 7 in Zigong, Deyang, Panzhihua and other cities), 2 second-level testing and maintenance qualifications (Chengdu and Panzhihua each). Question 7: Will the temporary qualification be extended? A: The temporary qualification is valid for December 31, 2016, there is no relevant official document to explain whether it will be extended, the current number of registered fire engineers can not meet the demand for qualification, do not rule out the possibility of qualification extension. Question 8: When can I declare the qualification of a formal social fire technical service institution? A: Provincial policies vary, at present, only Guangdong Province in the country can declare formal qualifications, and there are three fire technical service institutions that have obtained formal qualifications (each employing 10 registered fire engineers identified in 2013). Question 9: Will Class II Certified Fire Engineer take the exam? A: The second class registered fire engineer qualification examination has not been started yet, because the total number of registered fire engineer certificates cannot meet the needs of applying for the qualification of fire technical service institutions, the second class registered fire engineer will start the examination this year Question 10: What is the impact of the draft of the new Fire Protection Law on registered fire engineers? A: Supplementary provisions in Article 17 of the draft for comments: Key units of fire safety shall have personnel qualified as registered fire engineers engaged in fire safety management. It also reflects that the registered units and scope of practice of registered fire engineers will be expanded to key units of fire protection, and after the formal implementation of the new Fire Protection Law, more personnel engaged in fire safety management will participate in the examination. What is the price of a registered Fire Engineer? What's the future? Factors determining the value of a Certified Fire Engineer certificate: 1, attribute difference: the gold content of registration certificate is higher than that of professional title certificate. Registration certificates are roughly: Registered fire Engineer, registered architect, registered structural engineer, registered Electrical engineer, registered utility engineer, registered Chemical engineer, registered urban planner, registered environmental engineer, registered Environmental Assessment Engineer, registered construction engineer, registered supervision engineer, blasting engineer, civil engineer, registered cost engineer, national cost officer, registered consulting engineer, etc . 2, entry threshold: the gold content of the certificate with a high entry threshold is higher than that of the certificate with a low entry threshold, which is proportional to the gold content of the certificate. 3, the number of certificates: The number of certificates is mainly determined by the number of people who take part in the exam and the exam pass rate, which also introduces the difficulty coefficient of the exam. In short, the harder the test, the lower the pass rate, and the most valuable. 4, market demand: the market demand is large, you are eating, when the market demand is shrinking, or the market is already in a saturated state, then your certificate is not worth anything. Summary: The gold content of the certificate with a high entry threshold is higher than that of the certificate with a low entry threshold, which is proportional to the gold content of the certificate.

For many students, the maximum allowable building area of the fire protection zone of civil buildings only needs to remember the table. In fact, only remember the table, cope with the exam is far from enough, but also pay attention to the following three misunderstandings: Misunderstanding 1: When there is an automatic fire extinguishing system, the maximum allowable building area of the fire protection zone of the equipment room? When the building is equipped with automatic fire extinguishing system, the maximum allowable construction area of the fire protection zone of the equipment room can be 2000㎡. Misunderstanding 2: When the automatic fire extinguishing system is set locally, what is the maximum allowable building area of the fire protection zone? Assuming that Sa+Sb is the maximum allowable building area of a fire protection zone, when the area with an automatic fire extinguishing system is 2Sa, the area of this fire protection zone can be increased by Sa (㎡), that is, S=2Sa+Sb, and the newly added Sa should also be equipped with an automatic fire extinguishing system. Misunderstanding 3: The maximum allowable area of the fire protection zone of the shop business hall and the exhibition hall can be 10,000 square meters under what circumstances? In the shop business hall and exhibition hall of the first and second fire-resistant grade buildings, when automatic fire extinguishing system and automatic fire alarm system are set up and non-combustible or non-combustible decoration materials are used, the maximum allowable building area of each fire protection zone shall comply with the following provisions: 1 Set in a high-rise building, should not be greater than 4000 square meters; 2 Set in a single-storey building or only set in the first floor of a multi-storey building, should not be greater than 10000 square meters; 3 Set in the underground or semi-underground, should not be greater than 2000㎡. When the multi-storey store business hall is equipped with automatic fire extinguishing system and automatic fire alarm system and uses non-combustible or non-combustible decoration materials, the maximum allowable construction area of each fire protection zone shall be calculated in accordance with Table 5.3.1 of the Construction Regulations. Only when the shop business hall, exhibition hall is set in a single-storey building or only set in the first floor of a multi-storey building, the maximum allowable construction area of each fire zone can be 10,000 square meters.

Recently, Tiexi Tugong Comprehensive business District North a middle Road community to protect the home safety of the elderly in the area, eliminate fire hazards, under the unified arrangement of the Tugong comprehensive Business District Party Working Committee, door to door for eligible elderly people in the area to install independent smoke alarm. The installed independent smoke alarm can detect the smoke concentration in the room, and once the smoke concentration exceeds the standard, the alarm will automatically emit an alarm sound to remind the elderly that there is a danger in the house. In this way, the fire caused by careless fire or electrical fire can be prevented for the elderly, and then the fire hazards can be eliminated, and the fire safety protection for the difficult groups in the community can be implemented. In the work, the community was the first group of lonely elderly people over 80 years old in the area to install homes, and patiently explained the use of methods for the elderly to remind them to pay attention to the safety of using fire and electricity. Grandma Wang, 85, who lives alone, said happily: "The community is so thoughtful for us! We are old and have a bad memory, so we often forget to turn off the gas, and sometimes we burn the pot dry without even knowing that there is smoke in the house. Now with this little thing, if there is any danger, you will call the police. It is much safer."

Let the small fire deceased no longer happen, and let the home be healthy A dream come true! "Safety" and "health" are the rigid needs of people's life and the cornerstone of economic development. In different eras, people have different understandings of "safety" and "health" and derive different needs. China's current economy has entered the second half, and it is also experiencing "the world today is going through great changes unseen in a century". In the changing situation, people's needs are different, and the connotation and extension are advancing with the times. With the continuous change of modern technology, smart products are accelerating into thousands of households. In the first half of 2021, China's smart home equipment market shipped about 100 million units, a year-on-year increase of 13.7%. Authoritative organizations predict that my country's smart home equipment market shipments will continue to grow at a compound growth rate of 21.4% in the next five years, and the market shipments will be close to 540 million units in 2025. Such a broad market still cannot solve the two social rigid needs of "home safety" and "home health care". Tiancheng Group focuses on the field of smart security, aiming at the 30 billion residential area, the frequent occurrence of "small fire deaths (if you are familiar with people, what would you think)" accidents, and the trillion-level "silver economy (our How should parents be healthy)", aiming at more than 400 million families in my country, pioneering the combination of "home safety" and "home health care", focusing on the two key points of "safety" and "health" for people's livelihood, to create a "home" "Safety, home health care" whole system plan, fully meet the current people's growing needs for a better life. 1. Analysis of social rigid needs (1) Status of home security my country has a population of 1.4 billion and more than 300 million families. The family is the smallest unit of society, and the residences where families live are also the places most affected by fires. According to statistics from the Fire and Rescue Bureau of the Ministry of Emergency Management, a total of 748,000 fires will be reported in 2021, with 1,987 deaths and 2,225 injuries, and direct property losses of 6.75 billion yuan. Among them, the number of residential fires only accounted for 34.5% of the total, but the dead accounted for 73.8% of the total. This is the most threatening "small fire death" incident in today's home security. "Small fire deceased" is an abnormal phenomenon of fire deceased people. Although there are various reasons for its formation, most of them are caused by people's negligence of prevention and lucky violations. The reason for the frequent occurrence of "small fire deaths" accidents is mainly due to the fact that the safety concept has not kept pace with the material conditions. Over the past 40 years since the reform and opening up, the living standards of urban residents have undergone earth-shaking changes. The per capita living area has soared from 4 square meters in the early days of reform and opening up to 32.91 square meters of urban per capita residential construction area. Living conditions range from five generations sharing one room to a family of three with three bedrooms and two living rooms or even a duplex mansion. The great changes in living conditions have also put forward higher requirements for our home security concept. In the past, there were very few electrical appliances in the home, and economic conditions did not allow more electrical appliances to work all night, so the possibility of fire at night was low. , The shabby room is not large and the floor is not high to facilitate escape. Although the property may not be preserved, the problem of life preservation is not big. Nowadays, adults and children have their own bedrooms. The living room, dining room, and kitchen are unattended at night. There are too many long-powered devices such as refrigerators, air conditioners, routers, set-top boxes, and chargers. If there is a fire in the living room at night, the bedroom with the door is closed. It is difficult for residents to get early warning of fires. Multi-storey and high-rise residential buildings lack a variety of escape routes, and the 3 minutes most conducive to escape in the early stage of fire are easily missed, which is also the root cause of the frequent occurrence of "small fire deaths". Due to the particularity of home safety, it is not feasible to apply the idea of fire prevention in social enterprises and institutions to home safety. Many local government-led home alarm installation and promotion work has resulted in frequent false alarms and equipment failure due to unstable product detection. The high power consumption of communication led to fatal reasons such as frequent power outages, and finally ended in failure. Many households dismantled them within a short period of time after installation. Today's hot NB-IoT products not only do not solve the above problems, but require the government and/or households to bear the cost of equipment procurement and installation, and also bring additional "monthly traffic" costs. Due to the dilemma of installing alarms at home, people have hoped that home security products can enter thousands of households with today's popular "smart homes". However, in the huge development situation of smart home, residential fire alarm seems to be separated from the smart home system. In homes covered by digital home networks, fire detection and alarms are creating a loophole. The reason is that fire protection products have the characteristics of large electronic systems, full life cycle operation, and high reliability requirements in complex environments, which are extremely difficult to manufacture. At the same time, the stability requirements of household products are higher. Once a false alarm occurs, it will cause unnecessary panic, bring a very poor experience to users, and further affect the image of the brand in the minds of consumers. In addition, most of the home application scenarios are installed after decoration. The installation of traditional wired products will destroy the original decoration and cannot meet the actual needs of customers. These factors prevent smart home product integrators from entering this troublesome and special field. At the same time, since neither the national code "Code for Fire Protection in Architectural Design" nor "Code for Fire Protection in High-rise Civil Building Design" stipulates that fire detection equipment must be installed in family residences, this also causes the development of home safety to lag behind economic development and is not synchronized with the smart home system. development trend. (2) Current status of home health care The Chinese traditional "one hundred kindness and filial piety first" need to carry forward the traditional virtues even more in today's increasingly serious population aging problem in our country. It is urgent to establish a high-end, technological and service-oriented "home health care" system that can be perfectly integrated with the home security system. On May 11, 2021, the results of the seventh national census showed that China's population aged 60 and above was 264.02 million, accounting for 18.70%, of which 190.64 million were 65 and above, accounting for 13.50%. With the increasing aging of society, there are more and more elderly people in China, and the proportion of the population is also increasing. The aging population continues to increase, and the aging rate has increased from 14% to 16%. At the same time, the trend of deep aging continues to increase, the population over the age of 75 continues to increase, and the number of elderly people who rely on social support and do not have the ability to live on their own is also gradually increasing. In addition, the distribution of aging in my country is becoming more and more uneven. Some elderly cities have an aging population of more than 30%. The aging degree of super-first-tier cities such as Beijing, Shanghai, Guangzhou and Shenzhen is extremely serious. Taking Beijing as an example, nearly a quarter of the registered population is over 60 years old. The degree of chemistry ranks second in the country. In 2020, the registered elderly population in Beijing will exceed 3.8 million, and the resident elderly population will exceed 4 million. There is a huge demand for professional health care services. From 2015 to 2050, it is a critical period for a large number of only-child parents in China to enter old age. They will change from traditional multiple children taking care of one elderly person to one only child taking care of at least two elderly people. The huge pension pressure will become an urgent problem for the whole society to solve. . Over the years, my country has been advocating that 90% of the elderly should take care of themselves at home, 6% or 7% of the elderly in community institutions, and 3% or 4% of the elderly in institutions such as nursing homes. However, with the deepening of the aging of the population in my country, social pensions have encountered many new problems and challenges. In some places, there have been phenomena such as the difficulty of finding a bed in public nursing homes and the high prices of private nursing homes. And due to the influence of traditional culture, most of the elderly prefer to take care of themselves at home, relying on the family and the community for the elderly. The family is the most important part of the entire pension system. Elderly people who live alone are a group of people who need more attention than empty-nest elders. The elderly who live alone live at home alone, various safety hazards not only threaten the safety and health of the elderly, but may even lead to social security problems, which should be paid attention to by all aspects. Although the innovation of the service model and the empowerment of digitalization have improved the pension system to a certain extent, there is still a long way to go from "home health care". For example, smart watches, smart blood pressure monitors, smart blood glucose meters and other "smart devices" that can be connected to the Internet, but need to download multiple APPs, the products cannot be linked together, and the health data cannot be comprehensively analyzed. Many "data silos" have been formed, which makes it impossible for children to meet their actual health needs even if they purchase advanced equipment for their parents.

Since China entered the "Internet+" era, many things have changed our way of life, such as 5G, mobile payment, sharing economy, e-commerce industry, take-out industry, etc. Their success not only benefited from the dividends of the times and their advanced technology, but more importantly, they all brought convenience to customers and shared benefits with partners with "Internet thinking". Tiancheng Group, as a global technology company with "smart safety service" as its core, has always been deeply involved in the smart safety field for many years. Since the beginning of 2016, the Group has invested hundreds of millions of yuan in research and development, built six platforms covering the field of urban smart safety, completed the whole process solution from data collection, storage and analysis to smart application, and formulated a set of cooperation mode and business framework for creating, acquiring and distributing value, providing stable profits for stakeholders and partners, and further providing guarantee for the landing of smart fire . Under the environment of national policy orientation, comprehensive technological innovation and escalating demand, the construction of smart fire control has become an urgent need of the whole society. In recent years, a large number of practitioners have made various attempts, but they have not found the equilibrium point between the real market demand and the platform profit. As the leader of smart fire protection solutions, Tiancheng Group seized the historic opportunity, integrated the advantages of "platform+hardware+service", applied "Internet thinking", and worked out six profit profit points for different application scenarios and different partners to meet the real needs of society, solve the pain points and difficulties of smart fire, and provided classic solutions for the industry. To change the times, we need a win-win driving force! Tiancheng Group makes profits by six platforms, and gathers more industry peers! Tiancheng Group will take advantage of the situation, deepen the field of smart safety services, actively promote the implementation of smart fire protection, and make unremitting efforts to build smart cities and change people's lives!
