Underground cable positioning thermometer and application thereof

Abstract

The invention discloses an underground cable positioning thermometer which comprises a temperature sensor, a main control chip MCU, a radio frequency chip, an LC oscillating circuit and a power supply. The main control chip MCU is connected with the temperature sensor and the radio frequency chip, the LC oscillating circuit is connected with the radio frequency chip to achieve signal receiving and sending, and the power supply is used for supplying electricity to the components. The underground cable positioning thermometer overcomes the defects that fault discovery is not in time and repair, maintenance and searching are inconvenient due to the fact that buried cables are buried underground and provides a rapid response means for maintenance of the cables. Meanwhile, by using the underground cable positioning thermometer, an underground cable temperature data obtaining system can be established, an underground cable temperature data network is formed after temperature data are collected in real time, the data can be used for analysis of big data, and a reference is provided for study of the operation condition of the macro economy.

Description

technical field [0001] The invention belongs to the technical field of sensor measurement and Internet of Things application, and in particular relates to an underground cable positioning thermometer for measuring the temperature data of underground cables. Its temperature is accurately measured and collected. Background technique [0002] In the power industry, there are usually two ways to lay high-voltage cables: (1) high-altitude erection; (2) underground laying. This method has its own advantages and disadvantages. It is easier to find the cause and solve the fault when a cable fault occurs when the method of high-altitude erection is adopted. , At the same time, because the cable is directly in the external environment, it is susceptible to interference from weather and other factors to cause failures. In addition, the high-voltage cables on the outer frame are also a hidden danger to the safety of urban life personnel. For this reason, in the city, usually adopt th...
