Temperature detection system and detection and alarm method based on combined manhole cover

Abstract

The invention relates to a temperature detection system and a detection and alarm method based on a combined well cover. It includes a well cover seat ring, an outer cover for closing the well cover seat is arranged on the upper part of the well cover seat ring; an inner cover is also arranged in the well cover seat ring, and an opening is opened on the inner cover, and the opening is embedded There is a waterproof installation box, and a circuit board is arranged in the waterproof installation box, and the circuit board is provided with an MCU and a temperature sensor connected to the MCU for detecting the temperature of the cable in the well, a power supply for providing power to the circuit board, and a power supply for the circuit board. A communication circuit for communicating with the manhole cover monitoring server, the communication circuit includes an antenna. The method of the invention collects the temperature of the downhole cable in real time through the temperature detection system, thereby ensuring the safety of the downhole cable.

Description

technical field [0001] The invention relates to a temperature detection system and a detection and alarm method based on a combined well cover. Background technique [0002] The well cover is the closure on the top of the entrance and exit leading to the underground facilities. It is necessary to install the well cover in all places where public facilities such as running water, telecommunications, electricity, gas, heating, fire protection, and sanitation are installed. With the rapid development of my country's economy, my country's infrastructure construction has ushered in a new cycle, and the market demand for manhole covers in urban planning and road construction is huge. However, manhole covers are rolled and damaged from time to time, resulting in a decrease in the safety of roads and facilities. [0003] Manhole covers in the road are mainly used to cover the deep wells on the road. According to the different underground pipelines, some deep wells are used as water...

However, manhole covers are often crushed and damaged, which reduces the safety of roads and facilities

[0003] Manhole covers in the road are mainly used to cover the deep wells on the road. According to the different underground pipelines, some deep wells are used as water pipelines, line pipelines or gas pipelines. The setting of deep wells is conducive to the maintenance of pipelines. However, in some special cases Under heavy rain or human factors, the manhole cover is removed and people or objects fall into the deep well, or are jacked up by the impact of the internal pressure of the deep well. These phenomena will bring huge safety hazards to people's travel.

At the same time, when the manhole cover is used as a cable and line pipeline, criminals often steal the cable by removing the manhole cover, which brings losses to national property.

[0004] The traditional manhole cover is a single-layer structure, which is easy to be damaged due to rolling, and does not have the temperature acquisition function of the cables installed under the manhole cover, and cannot monitor the temperature information of the cable under the manhole cover in real time, so it is impossible to determine whether there is a short circuit in the cable under the manhole cover or other failure
