Infrared temperature monitoring system for miniature cabinet

Abstract

The invention discloses an infrared temperature monitoring system for a miniature cabinet. The infrared temperature monitoring system comprises an infrared temperature sensor, a multi-way selector switch, a thermocouple digital converter, a single-chip microcomputer, an LCD, a wireless communication interface and an alarm circuit. The signal output end of the infrared temperature sensor is connected with the temperature signal input end of the multi-way selector switch. The temperature signal output end of the multi-way selector switch is in communication with the temperature signal input end of the single-chip microcomputer. The change-over signal end of the single-chip microcomputer is in communication with the change-over signal end of the thermocouple digital converter. The LCD, the wireless communication interface and the alarm circuit are respectively in communication with the single-chip microcomputer. The technology of infrared temperature measurement is adopted, and non-contact temperature measurement and acquisition are achieved; in addition, the switch cabinet is used as a unit, signal transmission is performed in a wireless mode at a short distance, and therefore the infrared temperature monitoring system is simple in structure, small in size, low in power consumption and capable of achieving online temperature monitoring.

Description

technical field [0001] The invention relates to an infrared temperature monitoring system, in particular to a miniature cabinet infrared temperature monitoring system. Background technique [0002] During the long-term operation of the power system, the contacts and bus bar connections in power plants and substation switchgears often generate heat due to aging or excessive contact resistance, resulting in fires. In order to prevent the occurrence of these hidden dangers, it is necessary to strengthen the monitoring of the contact temperature of the switchgear during operation, judge the fault point in time, and eliminate the fault in the bud. [0003] At present, most domestic high-voltage cabinet temperature measurement devices use commercial infrared thermal imaging cameras. This kind of equipment has complex structure, large volume, large power consumption, and high price, so it cannot be used for online temperature monitoring. In addition, the communication method used ...

Problems solved by technology

[0003] At present, most domestic high-voltage cabinet temperature measurement devices use commercial infrared thermal imaging cameras. This kind of equipment has complex structure, large volume, large power consumption, and high price, so it cannot be used for online temperature monitoring.

In addition, the communication method used by the traditional monitoring platform affects the overall performance of the system due to its high cost and the need for wiring.

Through the above analysis, it is not difficult to find that the existing similar systems and test products have limitations such as low efficiency, high cost, high energy consumption, and difficult implementation.
