Embodiment 1

[0027] Embodiment 1: An intelligent electronic manhole cover system includes an electronic manhole cover, a cable channel located under the electronic manhole cover, a sensor module located inside the cable channel, and a remote control platform. The electronic manhole cover includes an Internet of Things module, a cellular communication module and a control system. module, the sensor module communicates wirelessly with the electronic manhole cover through the Internet of Things module, the cellular communication module communicates wirelessly with the remote control platform, and the Internet of Things module is wired / wirelessly connected to the cellular communication module.

[0028] The sensor module includes a gas sensor, a temperature sensor and a water level sensor, the gas sensor is a CO sensor, the temperature sensor measures the internal temperature of the cable channel, and the water level sensor measures the water level of the cable channel.

[0029] The electronic m...

Embodiment 2

[0045] Example 2: At the same time, according to statistics, most of the faults inside the cable channel are caused by too high water level, especially under the influence of extreme weather such as urban waterlogging in summer, the inside of the cable channel often causes faults due to excessive water accumulation. The control method in the above-mentioned embodiment 1 is suitable for basically all situations, but for urban waterlogging, in order to prevent the control module from locking the manhole cover with an electronic lock, which will affect the rescue work of rescuers, the control module also includes a separate processing channel The detection operation circuit of the internal water level signal, the integral comparison circuit and the comprehensive control circuit.

[0046]The detection operation circuit uses the liquid level sensor U1 to replace the float liquid level switch as the water level detection sensor to detect the water level signal in the cable channel, a...

Abstract

The invention discloses an intelligent electronic manhole cover, which effectively solves the problem of false locking of the manhole cover in the prior art when the water level signal is inaccurate. The comparison detection circuit of the present invention uses the liquid level sensor U1 to detect the water level signal, and after the water level signal is subtracted, the integral comparison circuit is turned on, and the water level signal is transmitted to the integral comparison circuit, and the integral comparison circuit integrates and compares the water level signal to obtain a comparison signal, and the comparison signal will comprehensively control The circuit is started, and the integrated starting circuit starts the automatic drainage pump and the manual drainage pump respectively, and at the same time uses the manhole cover controller to control the manhole cover, and outputs an alarm signal to the control center, realizing the intelligent control of the manhole cover and ensuring the safety of the cables in the cable channel. Safety, but also to ensure the safety of people's use of electricity.

Description

technical field [0001] The invention relates to the technical field of manhole covers, in particular to an intelligent electronic manhole cover. Background technique [0002] With the gradual increase of high-voltage cables entering the ground and the rapid development of underground cable channel construction, the number of cable channel inspection wells is increasing, and the layout is scattered regionally. The manhole covers are mostly located on roads or sidewalks, often facing criminals stealing power facilities, construction and illegal excavation and other external force damage problems, the management work of the power supply department is becoming more and more difficult, and it is difficult to monitor the daily operation and management work in real time by relying solely on manual inspection. The effective integration with the status monitoring of the cable body leads to insufficient utilization of resources and seriously affects the reliable and stable operation o...
