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 well lid which solves the problem that in the prior art, when a water level signal is inaccurate, a well lid is locked by mistake effectively. A comparison detection circuit detects the water level signal in a cable channel through a liquid level sensor U1, subtraction is conducted on the water level signal, and then an integral comparison circuit is started; a water level signal is transmitted to the integral comparison circuit, the integral comparison circuit integrates and compares the water level signal to obtain a comparison signal, the comparison signal starts the comprehensive control circuit, the comprehensive starting circuit starts an automatic drainage pump and a manual drainage pump respectively, and meanwhile, the well lid controller is used for controlling the well lid. The alarm signal is output to the control center, so that intelligent control on the well lid is realized, the safety of the cable in the cable channel is ensured, and the electricity utilization safety of people is further ensured.

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...
