With the rapid development of urban infrastructure construction in my country, various municipal public underground pipeline facilities such as communications, gas, water supply, drainage, heating, and electricity are increasing in the city, and the manhole covers of various underground pipeline facilities on urban roads are correspondingly constantly increasing. increase. In recent years, due to poor management of urban pavement manhole covers, the phenomenon of manhole covers being stolen and damaged without timely management has caused various injuries and car damage incidents throughout the country, which have seriously affected the travel safety of citizens and caused a bad society. Impact, how to improve and strengthen the management of urban manhole covers has become a difficult and hot issue that plagues municipal facilities management departments across the country, and has attracted great attention from local governments and municipal facilities management departments. Especially after the manhole covers on some road sections are lost, it is difficult to determine the nature of the well, so that it is impossible to find the property right unit in time for timely repair. As the domestic RFID radio frequency technology becomes more and more mature, it is no longer a fantasy to use the characteristics of RFID radio frequency technology to realize the effective traceability supervision and management of the manhole cover, and to maintain the safety of roads and ground wells. Through RFID radio frequency technology, each manhole cover and well location are given an electronic label to record information. Once the manhole cover is lost, only the electronic label can be scanned to immediately identify the property right unit, and the manhole cover can be reinstalled in the shortest time. Each manhole cover has an RFID electronic tag, which is also convenient for inspection and management. The real realization can be retrospectively supervised, which facilitates the institutionalized management of relevant departments.
1. System composition
The RFID manhole cover management system is a platform based on RFID technology composed of special low-frequency electronic tags for manhole covers, readers, RFID handsets and background management software.
2. System operation flow chart
Third, the significance of the RFID management system
(1) RFID electronic tags can be packaged into various forms according to the requirements of use, and can adapt to various harsh environments such as oil stains, dust pollution, and rain washing. Therefore, for equipment that is often used outdoors, the use of RFID tags as asset identification can effectively solve the damage to the tags in the outdoor environment and ensure the safety and reliability of the manhole cover data.
(2) Radio frequency technology uses radio carrier communication technology to realize data exchange, which can realize non-contact and invisible reading of tag information. Moreover, RFID tags can store data and write data repeatedly up to 100,000 times. In the manhole cover management, the shell is closed after installation and commissioning, and it cannot be opened without special reasons.
(3) Using RFID electronic tags as the manhole cover tag card, key data such as the main information of the manhole cover can also be recorded in the tag. Because each RFID electronic tag has a globally unique ID number, the ID number is written in the ROM process mode during the production of the integrated circuit and cannot be changed. Therefore, the RFID electronic tag cannot be copied or exchanged. During the inventory, the handheld device can be used to read the data of the RFID electronic tags installed inside the device without opening the device casing, and at the same time, grasp the key information of the manhole cover. RFID electronic tags are installed inside the equipment, which is more secure and confidential. Under normal conditions, the detailed information of the device can be grasped in time by reading the label information. Because RFID electronic tags cannot be imitated, the information on the manhole cover can be checked in time to quickly grasp the loss of the manhole cover.
(4) The manhole cover management system with radio frequency technology has been added to further strengthen the monitoring of manhole covers, ensure the safety of assets, and ensure the integrity, accuracy and reliability of asset data.
