The municipal manhole cover intelligent management system in this plan integrates active radio frequency identification technology, sensor technology, geographic information technology, computer network technology and other wireless communication technologies and other Internet of Things related technologies, forming a foundation by building smart gateways on urban streets The perception network realizes the integrated real-time monitoring and management of the active perception, timely warning, and command linkage of the status of municipal manhole covers. The construction and application of this system has innovated the management mode of municipal manhole covers, improved the management process of municipal manhole covers, and comprehensively improved the level of urban refined management.
1. System function
1. Information management: The identification card installed on the manhole cover can record the location, property rights, contact person, telephone and other attribute information of each manhole cover, and the management department can count the manhole cover information in real time.
2. Real-time positioning: Through the software plan, you can view the location and attribute information of the manhole cover in real time, locate the specific location of field personnel and vehicles in real time, and facilitate the unified scheduling and management of the monitoring center.
3. Anti-theft supervision: The manhole cover identification card has a built-in tilt and vibration sensor. Under normal conditions, the identification card is in a dormant state. When the manhole cover is opened abnormally, the identification card immediately sends out an alarm signal.
4. Alarm linkage: After an alarm is generated by the monitoring center of the alarm message box, the alarm information will be sent to the mobile phone login client of the relevant person in charge and the manager at the same time.
5. Positioning and tracking: the manhole cover is stolen, the system can display the moving track of the manhole cover in real time, combined with the system to display the location of the management personnel, it is convenient for the monitoring center to uniformly command and dispatch, and intercept and track in time.
6. Authentication setting: When the engineer is maintaining the manhole cover and line, the monitoring center can legally disarm it, or the authorized engineer can hold the terminal device to match and disarm it.
7. Data analysis: According to the needs, from different angles and maintenance, the large amount of data in the system can be reorganized, summarized and compared and analyzed to mine valuable data that is more conducive to improving the level and efficiency of municipal management.
2. Related fields of expansion
1. Street lamp management, equipment box management, municipal asset management
2. Municipal vehicle supervision, municipal personnel supervision, outdoor billboard management, incident handling process
3. System advantages
(1) Advanced technology: the perfect integration of active RFID radio frequency and intelligent sensing technology, the system can remotely monitor the opening, movement, and theft of the manhole cover in real time.
(2) Reliable transmission: The unique spread spectrum modulation transmission technology of 433MHz is adopted, which has the characteristics of strong penetration, long transmission distance, strong anti-attenuation ability, and strong anti-interference ability to ensure effective signal coverage and transmission.
(3) High security: The self-developed built-in encryption protocol ensures stable data interaction in the system and prevents link detection and cracking.
(4) Accurate judgment: The identification card actively perceives the real-time status of the manhole cover, and its design adopts advanced attitude, vibration, and position recognition algorithms, which can effectively prevent false alarms.
(5) Long use time: The identification card circuit adopts a low-power design, and has a dual switching mode of activation and dormancy, which makes the application time longer.
(6) Simple construction: The appearance design of the identification card and the base station fits the actual installation environment of the manhole cover, and the construction is simple without laying any cables.
(7) Convenient maintenance: The battery in the identification card is replaceable, easy to disassemble, and firm and reliable after installation.
