In the event of an abnormal situation, the base station will identify and issue an alarm, and the municipal staff will immediately carry out emergency treatment, effectively ensuring the safety of municipal public assets.
Handheld
Handheld machine, built-in Bluetooth module or UHF UHF radio frequency module, can connect and communicate with the tag, read and write the related parameters of the tag, and can receive the dangerous signal sent by the background to process the dispatch task, which is convenient for management personnel Deal with all kinds of abnormal actions of the target carrier in time.
3.2.2 Software system
The software system has high stability, high maturity, and good compatibility, and can be processed in detail according to needs for use. The system is developed with J2EE technology, and a general programming language and operating support environment are used in the design process, so that the system has good customization.
The back-end system adopts B/S architecture, and its main function is to realize real-time monitoring and intelligent management of municipal assets. The system is connected to the RFID reader on the public network to detect the electronic tags in the area in real time; at the same time, the electronic tags upload sensor data every few seconds (settable), and the background system obtains the target carrier’s information through the analysis of the tag data. Moved, uncovered, damaged, etc. The development of this system aims to solve the shortcomings of the lack of real-time mechanism for traditional target carrier management, and propose an intelligent, efficient, and municipal asset facility management solution to simplify the administrator’s work of patrolling municipal assets, thereby concentrating their efforts, Quickly respond to the abnormal situation of the target carrier and improve the work efficiency of managers.

4. System advantages
Complete real-time monitoring of the status of all target carriers, and know the status of the target carrier in real time. Abnormal situations will be distinguished according to the alarm category, such as coordinate offset, abnormal translation, overall flip, offline, etc., and the system can provide alarm status handling Levels such as emergency, urgent, general, etc., road section construction status, alarm level, alarm content query, complete positioning and traceability of target carriers, alarm linkage, dispatch command, plan management, remote control, security protection, remote maintenance, statistical reports And other service functions.
The application of this system can effectively manage municipal public assets, greatly improve the response speed, work efficiency and reduce the error rate of the competent departments, change the previous work mode that used a large number of manual statistics and inspections, and introduce information technology into smart urban management
5. System Application
The system is used in municipal facilities such as manhole covers, trash cans, street signs, and urban sculptures. The status is monitored, judged, and alarmed 24 hours a day, and the municipal personnel perform maintenance and management in a timely manner. The use of this system improves the efficiency of manual maintenance and avoids personal injury. Safety issues such as property damage.
5.1 Manhole cover
At present, the management of urban manhole covers is basically in a state of manual management, which is time-consuming and labor-intensive and has little effect. There are still many accidents occurring. Our company uses advanced radio frequency communication technology to design a set of remote management solutions for urban manhole covers. The system is used to monitor the state of manhole covers and the environmental conditions in the manhole, so as to realize the active warning and alarm of manhole covers and avoid damage to the manhole covers.

The municipal personnel perform emergency response in time based on the received information, thereby effectively protecting the municipal public Asset safety; this project has completed the country’s first demonstration and carried out large-scale applications.
5.2 Trash can
At present, the city’s management of trash cans is based on the principle of who uses who manages. The comprehensive management department assigns the trash cans to various departments for management and use after they are numbered and archived. The user department arranges special personnel or rotates for management, and the responsibility belongs to each person; here Under this management status, there are often problems such as overflowing trash bins and stinking odors for timely treatment.
This system can be used to monitor the status of trash bins. When trash overflows and foul odor occurs, the electronic tag will send out an alarm message, and the background management personnel will respond in time through the alarm type and level displayed on the platform; this system will respond to trash. Effective management of barrels makes the city cleaner
5.3 Street signs
At present, the management of road signs is also in a state of manual management, managed by different undertaking departments and units, and lacks effective management strength and efficiency; once the road signs have problems, it will bring inconvenience to drivers and other derivative hazards.
The application of this system can circumvent the above problems, and carry out 24-hour management and control of road signs. Once abnormal conditions such as damage, collapse, movement, etc. are detected, the electronic tag will implement the alarm function, and the management staff will respond to the work in the first time; completely improve The current management status allows all information, problems, and conditions of street signs to be displayed on the platform in a standardized manner.
5.4 Street lights
The detection of the brightness, damage, loss, theft, etc. of the street light ensures the brightness of the road at night.
At present, the management of street lights uses manual inspection methods, including regular inspections and special inspections; regular inspections are inspections every few days, and special inspections are immediate inspections when encountering special events and bad weather. Lack of timely and effective management of street lights.
Using this system, it can detect the brightness, damage, loss, theft of street lights, and the collapse and damage of street light poles. When an abnormality occurs, the electronic tag will send out an alarm message, and the management personnel will make emergency treatment based on the received information , So as to standardize and effectively manage street lights and prevent related accidents.
Based on the above, it can be seen that the current urban facilities lack efficient and powerful management. The management system developed by our company can accurately, standardize and present the information, current situation, management, and maintenance of urban facilities on the management platform.
