Switch cabinet monitoring device and monitoring method thereof

A switch cabinet monitoring device provided by the present invention comprises a switch cabinet, a monitoring device and a plurality of detection devices, the plurality of detection devices comprise humidity sensors installed on the outer side wall of a shell and infrared temperature measurement probes located at different positions in the switch cabinet, and the infrared temperature measurement probes are fixed through swing pieces. And the infrared temperature measurement probes are connected with the control module through wireless communication. The monitoring method of the switch cabinet monitoring device comprises the steps that S1, a motor is started firstly, and the output end of the motor drives a main shaft to rotate; s2, the infrared temperature measurement probes collect infrared rays emitted by an electrical apparatus element; s3, the acquired data is sent to a communication module, and the data is processed through a mainboard; and s4, the processed data are displayed through a displayer, and an alarm device gives an alarm when the temperature exceeds the early warning range. The motor drives the main shaft to rotate, and the mounting seat drives the infrared temperature measurement probes to rotate, so that the detection area of the infrared temperature measurement probes is increased, and detection blind spots are reduced.
