1. Introduction to the system
When many cities still use cast iron manhole covers in large quantities, how to prevent theft is still a headache for municipal administrations at all levels. 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.useRFIDThe characteristics of technology (radio frequency technology) are used to realize the retrospective supervision of the manhole cover and maintain the safety of roads and wells; once the manhole cover is lost, only the electronic tag can be scanned to immediately identify the property right unit, and the manhole cover can be reinstalled in the shortest time.
2. System composition
The RFID municipal manhole cover management system consists of a special electronic tag for the manhole cover,Reader, Card issuers, handheld readers, mobile readers, background management software, and middleware platform based on RFID technology.

4. System implementation benefits
(1) The label can be packaged in 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) RFID 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 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 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 tag cannot be copied or exchanged. During the inventory, the handheld device can be used to read the data of the RFID tag installed inside the device without opening the device casing, and at the same time, grasp the key information of the manhole cover. RFID 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 the RFID tag cannot be imitated, the information of the manhole cover can be checked in time, and the loss of the manhole cover can be quickly grasped.
(4) The manhole cover management system with RFID technology has further strengthened the monitoring of manhole covers, ensuring the safety of assets and ensuring the integrity, accuracy and reliability of asset data.
