The Internet of Things is a new generation of security tools

With the development of society and economy, the demand for elevators in urban construction has increased rapidly, and the number of elevator production units has also increased. In recent years, elevator failures and accidents have also shown an upward trend, and there are still unclear responsibilities for security subjects in elevator safety supervision. Problems such as the low level of safety supervision, insufficient ability to pay for accidents, failure to implement repair funds, and vicious competition in the maintenance and protection market have seriously hampered the safe operation of elevators and have become an important hidden danger that threatens people's lives and property.

The General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) recently launched the “Elevator Safety Supervision Conference” campaign, and various regions and provinces across the country have responded positively with practical actions.

The Putuo Sub-bureau of Zhejiang Province has fully launched the elevator safety supervision and assembly campaign. In order to publicize elevator safety knowledge, investigate “two nos” elevators, “problem elevators” and other practical actions, strengthen the coordination of inspections, have hidden serious accidents, “two no” elevators, failure to implement rectification, management system is not implemented, safety management agencies (Equipped with) Inadequately equipped elevators and failure to implement the main responsibilities will be dealt with in accordance with the “Special Equipment Safety Law” to effectively protect the elevators.

Gansu Provincial Quality Supervision Bureau, Lanzhou City Quality Supervision Bureau and Chengguan District Quality Supervision Bureau jointly with elevator manufacturing companies, installation and maintenance units, elevator use management units and schools in Lanzhou City, "elevator safety into the campus, community" special education activities. This event combined with the training propaganda vehicle provided by the elevator manufacturing company, and promoted special equipment safety knowledge in various forms such as safety lectures, elevator component visits, related video demonstrations, safety knowledge consultations, and elevator exhibition boards to improve primary and secondary school students and the general public. The self-protection and safety civilization take the elevator consciousness.

In order to strengthen the awareness of elevator safety among the general public, especially young people, Xinjiang has assisted with the help of the Wujiaqu Bureau of Quality and Technical Supervision in Renmin Road, Junyu Road and Wujiaqu City with the assistance of a small, two small, and three small. From the 8th to the 12th of the month, carry out elevator safety knowledge into the campus and into the community series of publicity activities.

Tongnan County held an elevator safety supervision and congress promotion meeting and asked the 20 elevator maintenance and maintenance units in the area to carry out self-examination and self-correction immediately to investigate potential safety hazards, remove risks in a timely manner, and lift elevators with serious hidden dangers. All laws shall be suspended.

The Shanwei Municipal Bureau of Quality Supervision posted a free-to-use elevator safety knowledge logo on 2542 elevators registered in the city. Since the launch of a new round of elevator safety supervision and inspection work, we have inspected whether the elevator is in the inspection qualified period, whether the elevator inspection qualified mark is posted on the prominent position of the car, the safety management system and the emergency rescue plan are complete, and the elevator use unit is safe. Whether the management personnel hold certificates or whether the elevator maintenance work is standardized and supervise the safety management personnel of the property units to the Bureau to accept the free elevator safety management operation skill training, improve the management level of safety management personnel, and ensure the safe and stable operation of the elevator.

Passed formally at the 17th meeting of the Standing Committee of the 12th Provincial People's Congress, the "Guangdong Province Elevator Safety Regulations" will be implemented on October 1 this year. At that time, elevator accidents will injure the property and if the property management fails to fulfill its emergency rescue obligations, the maximum penalty will be a fine of 200,000 yuan.
Based on the Internet of Things, there is a new way to ensure the safety of elevators. Elevators are closely related to our lives. Regardless of whether they are residential quarters, offices, or shopping malls, we deal with elevators every day. Therefore, whether elevators are safe involves the lives of the people. . With the rapid development of the Internet and information technology, the Internet of Things has rapidly emerged. The applications based on the Internet of Things technology are based on various fields. The combination of the Internet of Things and security systems has also pushed the security industry to a new height. In the case of the Internet of Things elevator security, it provides a solution to elevator safety management. A good method has been widely recognized and applied throughout the country. The establishment of the elevator emergency rescue command center on June 9, 2014 in Suzhou City was based on the practical application of the Internet of Things technology and achieved good results.

Last year, the main failure of elevators was the rapid development of the economy and rapid urbanization. The number of elevators in Suzhou City has grown at a rate of about 20% per year in recent years. At present, the city of Suzhou has used more than 88,000 units of elevators, ranking first among prefecture-level cities nationwide.

The Suzhou Elevator Emergency Rescue Command Center is jointly responsible for the construction and operation of the Suzhou Quality Supervision Bureau and the Suzhou Municipal Public Services Center. Among them, the convenience service center of Suzhou City is responsible for the operation of the call platform, and the Suzhou Bureau of Quality Supervision is responsible for the construction and operation of the command platform. From June 9 last year to May 31 this year, the command center received a total of 12,734 alarms. It handled a total of 2,382 elevator breakdowns and saved 4,977 person-times. Among them, Suzhou City has handled a total of 2,195 elevator breakdowns and has rescued 4,639 people. Rescuers arrived at the scene with an average time of 17 minutes and 23 seconds. Implementation of the rescue took an average of 5 minutes and 46 seconds.

The database of 96333 shows that 1000 elevator failures were randomly selected during the past year. Among them, the door system problem was ranked first, accounting for 36.20% of the total, which mainly occurred on the anti-clamping device; the control system problem ranked second, accounting for 16.90%, appeared in the electrical connection, motherboard, elevator crashes and other issues; safety protection devices ranked third, accounting for 16.40%, appeared in the safety loop, lift the top, fire switches and other issues; other problems ranked fourth, accounting for 14.10%; external causes ranked fifth, accounting for 10.80%; electrical system problems ranked sixth, accounting for 4.70%; traction systems ranked last, accounting for 0.80%.

Decoration is an important cause of elevator failure Xing Dongsheng, Director of the Special Equipment Safety Supervision Department of Suzhou City Bureau of Quality Supervision, said in an interview: “The main reason for failure is renovation, because in the renovation process, many workers are rushing to catch up. Progress can't be used properly."

“Such as large-scale decoration products are operated by people using elevators, or cement is dropped into parts due to improper operation during transportation, or long fitting parts are placed against safety doors, etc., which can cause elevators. "The fault," said Xing, said: "In addition to the relevant data, we can see that during the period from October of last year to May of this year, the number of elevators in the industrial park was the highest, reaching 506, which is also because of industrial parks. The number of elevators in the elevator itself is relatively large, and there are many new houses and the decoration is relatively frequent.

In addition, elevator failures and the frequency of use also have a certain relationship. The reporter saw that the time period for the occurrence of sleepy people's failures was mainly concentrated at 8 in the morning and 10 in the morning, and 4 in the afternoon and 6 in the afternoon. It was the peak period of commuting. The second is the meal time from 10 noon to 2 noon.

The Director of Crimes reminds the public that once they have encountered an elevator failure, they must remain calm and calm. Immediately press the emergency button or call the repair number or call the 96333 hotline to find a professional rescue.

"Internet of things" will be the problem smashed in the cradle elevator rescue follow the "unified command, three-response" principle, that is, the call platform unified command elevator rescue, the failure of the elevator maintenance contracted maintenance unit as the main responsibility of the rescue, grid rescue units as In the responsibility grid area elevator rescue reserve team, on-duty engineers serve as the total reserve team for elevators in Suzhou.

However, in recent years, the number of elevators in Suzhou has been increasing rapidly. If the alarm is handled only by telephone, it is necessary to increase the ability to receive alarms in equal proportions, and the way in which telephones are alerted by police to implement elevator safety management is relatively passive and lagging.

As a highly mechatronic product, elevators rely on signals to generate signals. The signals (including faults) are transmitted and received centrally through the “Internet of Things” project. Through logical calculation, they can reach the command center. Automatically alert the police.

"Each elevator can be equipped with a remote monitoring system. It can send out signals, extract this parameter, send the error code to the original manufacturer or the quality supervision department, and maintenance personnel can carry out timely repairs with effective equipment." Xing Dongsheng He told reporters: "The original remedy was resolved beforehand and the problem was killed in the cradle."
