Low-power-consumption, simple and universal type cable well lid monitoring device

Abstract

The invention discloses a low-power-consumption, simple and universal type cable well lid monitoring device which comprises a stroke switch. The stroke switch is arranged on the well wall of the innerlower edge of a to-be-monitored well lid. A well lid state monitoring unit is arranged on the stroke switch. The well lid state monitoring unit is connected with an MCU control unit. The MCU controlunit is connected with a wireless communication unit, a clock unit, a data storage unit, a battery and voltage conversion unit, a power control unit and a debugging serial port. The MCU control unit monitors the opening and closing states of the well lid in real time through a well lid state monitoring unit circuit. The clock unit starts the MCU control unit in a timing manner according to a preset time interval so as to provide power for the wireless communication unit module and the data storage unit, the current well lid state is reported in time through the wireless communication unit, andthe wireless communication unit is connected with a background monitoring center. By means of the low-power-consumption, simple and universal type cable well lid monitoring device, real-time monitoring and timely alarming functions on the cable well lid state are achieved, and the safety protective property on the cable well lid is improved.

Description

technical field [0001] The invention relates to a monitoring device for a cable well cover, in particular to a simple and general-purpose cable well cover monitoring device with low power consumption. Background technique [0002] With the rapid development of electric power construction, the number of power cable tunnels and cable trenches is increasing, and the number of cable manhole covers is also very large. Since the high-voltage cables laid in cable tunnels and cable trenches are the lifeblood of the city, once When criminals invade illegally and carry out sabotage or theft, it will cause cable operation failure or damage and theft of equipment and facilities, and even cause large-scale power outages, which will cause a great safety accident. It is an ordinary non-intelligent manhole cover, which is an ordinary cast mechanical manhole cover. Therefore, in order to improve the reliability and safety of power transmission, it is necessary to monitor the switch status of...

[0002] With the rapid development of electric power construction, the number of power cable tunnels and cable trenches is increasing, and the number of cable manhole covers is also very large. Since the high-voltage cables laid in cable tunnels and cable trenches are the lifeblood of the city, once When criminals invade illegally and carry out sabotage or theft, it will cause cable operation failure or damage and theft of equipment and facilities, and even cause large-scale power outages, which will cause a great safety accident. It is an ordinary non-intelligent manhole cover, which is an ordinary cast mechanical manhole cover. Therefore, in order to improve the reliability and safety of power transmission, it is necessary to monitor the switch status of these manhole covers in real time, improve security measures, and avoid illegal intrusion and damage to power facilities. , and there is generally no external power supply available at the location of the manhole cover, and the monitoring device needs to be powered by a large-capacity battery, so the design scheme requires a low-power design, and the power consumption of the equipment is reduced by adopting some power consumption control methods, but How to design the monitoring device with lower power consumption is also a difficult problem to solve
