[0044] Bluetooth communication module: communicates with the mobile phone APP, receives commands, and can be turned on at close range in the event of a network failure at the device terminal.

[0045] Battery: High-performance battery is used, the system power supply voltage is 5V-12V low voltage, the capacity is not less than 60,000 mAh, and the power supply ensures that the terminal can work for at least three years.

[0046] Sensor: can monitor abnormal status of manhole covers, including illegal well opening, manhole cover status, peripheral status, etc.

[0047] Manhole cover mechanical components: Under the outer manhole cover, including telescopic rods and tail hooks, etc., to lock the manhole to prevent damage and prying.

[0048] The functional requirements of the device terminal are as follows:

[0059] Main functional requirements:

[0060] 1. The terminal equipment of the cable manhole cover control system should be embedded with an automatic activation program. The equipment is usually in a dormant state. Once the state of the manhole cover changes, the control circuit is automatically activated, triggering the alarm mechanism, and being able to report the state to the central platform in time, realizing real-time monitoring of the state of the manhole cover and the outer manhole cover.

[0061] 2. The terminal equipment of the cable manhole cover control system will also periodically (every 72 hours, which can be freely set) self-check the equipment status and automatically report it to the central platform. The platform can report the status according to the schedule.

[0062] 3. When the cable manhole cover control system terminal device receives the work order authorization, it should support close-range direct connection to the Bluetooth module in the device for the manhole cover involved in the work order to achieve close-range opening.

[0073] It is understandable that equipping the manhole cover with a manhole cover monitor based on trajectory analysis and inclination detection can monitor the movement status of the manhole cover in real time. When the manhole cover is flipped over or moved, an alarm will be activated immediately to notify the monitoring center.

[0074] Understandably, the main functions of the monitoring platform include manhole cover location map management, manhole cover asset management, real-time monitoring of manhole cover alarms, manhole cover fault dispatch processing, manhole cover inspection records, etc. Management agencies can understand information and formulate management strategies, organize and arrange manpower, conduct construction registration, and regional management through cloud servers and APPs.
