1. Overview of elevator certificate
The elevator is inspected once a year by the special equipment inspection department of the Technical Supervision Bureau. The qualified elevator will issue a qualified inspection report. In order to let passengers understand the safety of the elevator, an inspection certificate is usually posted on a conspicuous position of the elevator car. Indicates that the elevator pass inspection is qualified. The inspection department of the Technical Supervision Bureau expressly stipulates that elevators must be maintained by a qualified company, and that the maintenance company must perform maintenance twice a month. The Technical Supervision Bureau has taken great pains for elevator safety, but it is difficult to verify the implementation of the maintenance company, and it is difficult to define responsibilities when safety problems occur. Some unscrupulous companies and undocumented personnel also fake certificates to deceive users. How can we stop this phenomenon? How to carry out feasible registration management for elevator maintenance units?
2. Market prospects of RFID electronic elevator inspection certificate
Guangzhou special equipment refers to elevators, passenger ropeways, large amusement facilities, boilers, pressure vessels, etc. According to statistics, there are more than 24,000 special equipment users in Guangzhou alone, and there are about 180,000 special equipment, of which about 70,000 elevators are increasing every year, and the elevator certificate is replaced once a year. On a national basis, the demand is considerable.
3. The necessity of establishing anti-counterfeiting and information storage
Compared with developed countries, the accident rate of special equipment in my country is 4 to 6 times higher, and the situation in Guangzhou is much lower. However, many users do not pay attention to the safe use and management of special equipment, and they are under passive management and the equipment is out of date. If it is not checked, it will cause safety hazards.” Chen Yongtao, deputy director of the Special Office of Guangzhou Quality Supervision Bureau, said that the introduction of standards is mainly to implement and clarify the main responsibilities of users, so that users can clarify the use, maintenance, and safety management of special equipment. What are the detailed requirements and specifications of the company? How to deal with failures or accidents? At the same time, let functional departments classify and supervise the use of special equipment. The elevator user should entrust a qualified maintenance company to carry out the daily maintenance of the elevator. In order to supervise the installation monitoring to manage.
It is well known that elevators are indispensable for high-rise buildings. When you step into the elevator, have you noticed that the elevator may not have been “checked up” for a long time? For example, the maintenance unit does not carry out the two-monthly routine inspection of the elevator, it is like a dangerous building that no one manages. Our company conducted a random survey: citizens “do not feel” about the potential danger, is it safe to take an elevator without annual inspection? Interviews with more than 10 citizens taking elevators found that their vigilance for elevator safety is almost zero, which further reflects the importance of the management of the special equipment inspection department. According to the relevant national regulations on special equipment, elevators must be inspected by a special agency once a year, and they can be used only after passing the inspection and obtaining a certificate. Once uninspected is found, it will be shut down by the relevant departments and can be used only after passing the inspection. The question is how to supervise the company responsible for regular inspections? The emergence of RFID electronic tags can solve the problem of the special equipment inspection department of the Technical Supervision Bureau. The RFID paper ticket is embedded with the electronic certificate, which has the characteristics of direct surface printing, strong anti-counterfeiting ability, reliable ticket checking and accurate back-end statistics. Paper RFID electronic tags are not only cheap, but also can store information, and the information can be recorded in the chip. The special equipment inspection department of the Technical Supervision Bureau can know whether the maintenance company has carried out routine inspections in accordance with the regulations by extracting the information. It also knows the specific time of the inspection of the elevator maintenance company, the qualification certificate number of the inspector, and the fault code of the maintenance. etc.
Fourth, the technical parameters of using RFID electronic tags
1) Memory: 512bits
2) Frequency: 13.56MHZ
3) Reading distance: 6-12cm
4) Protocol: ISO14443A
5) Size: 86×54×0.8(+/-0.04)mm (or printed according to customer requirements)
5. RFID electronic elevator certificate
The RFID electronic elevator certificate is embedded with a smart “core” in the middle of the paper layer. It has the characteristics of direct surface printing, strong anti-counterfeiting ability, reliable inspection and accurate back-end statistics. Secondly, because it is embedded with a globally unique code The chip can completely eliminate fake certificates. The electronic certificate is verified by a handheld reader. The efficiency is extremely high. The reading and writing rate is 0.3 seconds per time, and it completely solves the multi-purpose phenomenon of one certificate. In addition, the electronic certificate system is all computers connected to the Internet, which effectively solves the problems of statistics, heavy workload, and high error rate.
The RFID electronic elevator certification solution is based on RFID technology, Guangzhou Fuqiao Electronic Technology Co., Ltd. has developed an RFID application program based on the development characteristics of the elevator industry. It can be “tailored” according to the actual requirements of different cities. Not only the cost is low, but also information can be stored, and the information can be recorded in the chip. The electronic certificate is a paper Mifare Ultralight chip, which has high stability and low price.
The RFID electronic elevator certificate code is a development of the global product code, which can identify targets outside the field of vision. The RFID electronic elevator certificate code is not just a radio wave bar code, it contains a series of data and information, such as the origin, date code and other key supply information. These information are stored in a small silicon chip using tags. , The network of the reader and the computer, you can get accurate information at any time.
RFID electronic elevator certificate can store data ranging from 512 bytes to 4 megabytes according to different types. The data stored in the RFID electronic elevator certificate is determined by the application of the system and the corresponding standards. For example, the label can provide whether the maintenance company has conducted routine inspections in accordance with the regulations, and it also knows the specific time of the elevator maintenance company’s inspection, the qualification certificate number of the inspector, and the failure code of the inspection and so on.
The storage status of the RFID electronic elevator certificate can also be used to identify the qualification of the maintenance company and the inspection personnel. These are similar to the information stored in barcodes. The tag can also be connected to a database to store information such as inventory number, current location, and status. Correspondingly, the RFID tag can directly determine the meaning of the code without referring to the database when reading data. RFID tags have been connected to many sensors, including those that can record temperature and humidity. When the environmental conditions change, the label can be reminded, especially when the change has an important impact on elevator passengers. In this sense, the RFID electronic elevator certificate has a certain “black box” effect.
Initially in the technical field, the transponder refers to an electronic module that can transmit information and reply information. In recent years, due to the rapid development of radio frequency technology, the transponder has a new concept and meaning, and is also called a smart tag or label. The reader (reader) of the RFID electronic elevator certificate performs wireless communication with the RFID electronic tag through the antenna, which can read or write the tag identification code and memory data. A typical reader includes a high-frequency module (transmitter and receiver), control unit and reader antenna.
6. Qualified anti-counterfeiting and information registration of RFID electronic elevators
The qualified RFID electronic elevator is based on Phillips MiFare technology and is compatible with ISO14443 air interface. The internal data of the chip is encrypted, and only a specific reader can read the data. Counterfeiters cannot produce the same certificate. Using RFID information storage technology, the user of special equipment uses the reader to fill in the grade when the maintenance personnel perform maintenance on time. The quality supervision department will perform A, B, C, D on each user based on the evaluation form during the law enforcement inspection. Four levels of safety management ratings. If any item is inconsistent, the rating result is D, and the unit must be ordered to make rectification. At the same time, record the maintenance time, personnel, qualification certificate number, hidden trouble code, etc. of the maintenance personnel of the security inspection department and maintenance company. Once the data is entered, it cannot be changed. The inspection department of the Bureau of Technical Supervision shall conduct the assessment during the annual inspection and renewal of the annual inspection. Effectively prevent the elevator inspection certificate from overdue or even without the inspection certificate, but also manage and supervise the elevator’s usual maintenance.
