With the rapid development of urbanization, the improvement of urban infrastructure has become an important topic, in the urban infrastructure, well cover as an indispensable part, plays an important role, however, the traditional way of well cover management has a series of problems and challenges. For example, well covers are geographically dispersed and large in number, and the traditional inspection method is costly and inefficient, which leads to many well covers being damaged without anyone knowing about it, thus causing potential safety hazards.
1. Difficulties of traditional manhole cover management
1.1 High cost and low efficiency
The traditional inspection method needs to consume a lot of manpower and material resources, which is costly and inefficient. Due to the dispersed and large number of manhole covers, the inspectors need to spend a lot of time and energy to complete the task and it is easy for them to miss or omit the inspection.
1.2 Safety Hazards
Due to the geographically dispersed location of manhole covers, traditional inspection methods are unable to detect damaged covers in a timely manner, resulting in safety hazards. For example, a damaged manhole cover may lead to a pedestrian fall or a vehicle accident, and if it is not detected and repaired in time, this safety hazard will always exist.
1.3 Untimely information
Traditional manhole cover management methods are unable to monitor the status of manhole covers in real time, resulting in problems that cannot be detected and dealt with in a timely manner. For example, a manhole cover that has been damaged may lead to more serious problems, such as burst water pipes and cable failures, if it is not detected in time.
1.4 Difficulty in data management
Traditional manhole cover management methods cannot effectively manage and record the basic information of manhole covers. Information such as the number of the cover, its location, and the road it is located on can usually only be recorded on paper, which is easy to be lost or difficult to locate, which makes the management and maintenance of manhole covers extremely difficult.

By using RFID electronic tag as the unique identification code of the manhole cover, the sensor can real-time monitor the information of the manhole cover’s location, condition and surrounding environment, etc. The sensor can transmit the collected data to the data collector through wireless communication technology, such as Bluetooth, Wi-Fi, etc.
3.2 Data Collector
The data collector is responsible for sending the data acquired by the sensors to the cloud server or local server. Through wireless transmission network, such as GPRS, 3G/4G, Wi-Fi, etc., the data collector can realize real-time monitoring and remote management, and the data collector can also be connected with other devices, such as cameras, sound sensors, etc., to acquire more environmental information.
3.3 Cloud server
The cloud server is used to store and process the data of manhole covers. Through cloud computing technology, large-scale data storage and analysis can be realized, and the cloud server can also provide functions such as data visualization and report generation, which is convenient for managers to analyze and make decisions on data.
3.4 Management Console
The management console is the user interface of the system, which is used for data supervision and control maintenance. Through the management console, the managers can view the status, location and historical data of the manhole covers in real time, and the management console can also provide the alarm function, so that the system will send out alarm signals to notify the relevant departments to take measures once abnormal situations are found, such as the manhole covers being damaged or shifted.
3.5 Mobile Terminal Application
Mobile terminal application allows managers to view the status and data of the manhole cover anytime and anywhere. Through the mobile terminal application, managers can real-time locate and monitor the manhole cover, view the real-time data and alarm information, and carry out remote operation and maintenance.
4. Program application benefits

Once someone breaks into the range of electronic fence, the system will send out an alarm signal and notify the relevant personnel to deal with it.
The advantages of electronic fences lie in the convenience of installation, wide coverage, as well as remote monitoring and management. However, there are some disadvantages of electronic fences, such as the need to access the power supply, susceptible to weather and other external factors.
5.2 RFID Technology
RFID technology is a kind of radio frequency identification technology, which can realize the remote monitoring and management of manhole covers. By installing RFID chip on the manhole cover, it can realize the unique identification and remote management of the manhole cover, as well as real-time monitoring of the manhole cover.
The advantages of RFID technology are high security, high reliability, no need to access the power supply and so on. However, the cost of RFID technology is relatively high and requires specialized technicians for installation and maintenance.
5.3 Physical locking
Physical locking is a traditional way of preventing theft chain of manhole covers, which is protected by adding locks and other physical devices on the cover. This way is simple and easy to do, but the lock is easy to be destroyed or the key is stolen, security is relatively low.
5.4 Well cover marking
Well cover marking is a simple and easy way of well cover anti-theft chain, you can add labels or spray marking on the well cover to facilitate management and monitoring. This way of low cost, but also easy to be malicious damage or tampering.
In summary, well cover anti-theft chain is an important work in urban management, need to use a variety of means for protection. Different anti-theft chain methods have their own advantages and disadvantages, need to choose and apply according to the actual situation.
