Coal mine explosion-proof electric appliance temperature rise wireless inspection system based on electromagnetic through-wall communication

Abstract

The invention provides a coal mine explosion-proof electric appliance temperature rise wireless inspection system based on electromagnetic through-wall communication, and relates to the technical field of explosion-proof electric appliance temperature rise tests. The system automatically detects the operation state of a temperature acquisition device, sets explosion-proof electric appliance test parameters, and sends a current adjustment instruction to a current generator; the host monitors current data in real time and compares the current data with a set value, when the actual current reaches the test current, a current adjustment stopping instruction is output, and test current adjustment is stopped; the data receiving and storing module acquires internal temperature data and environment temperature data of the explosion-proof electric appliance in real time according to the set interval time, and compares the internal temperature data and the environment temperature data with a set threshold value; the method comprises the following steps: acquiring temperature data of each position in the explosion-proof electric appliance, calculating a temperature rise value in test time, drawing a temperature change image and a temperature rise value change image, and outputting the maximum temperature rise value of each position, thereby realizing wireless temperature rise detection of the explosion-proof electric appliance in the coal mine.
