Temperature sensor for GWD (guide wave demultiplexer) coal mine

Abstract

The invention provides a temperature sensor for a GWD (guide wave demultiplexer) coal mine. The temperature sensor for the GWD coal mine comprises a sensor shell, wherein the sensor shell comprises a front cover and a rear cover; and an integrated mainboard, an information acquiring module, a displaying module, a communication module, a power module, an alarming module, a handle and an aviation plug are arranged in the sensor shell. The temperature sensor for the GWD coal mine can continuously monitor underground environment temperature of the coal mine, has on-site displaying and signal outputting functions, and can convert measured temperature into signals with frequency of 200Hz to 1000Hz; the signals are transmitted to a mine safety production monitoring system through a signal outputting unit, so that a function of automatically monitoring the underground environment temperature is fulfilled; a circuitry is controlled by a singlechip; zero temperature and sensitivity of the sensor can be adjusted through infrared remote control; a fault self-checking function is fulfilled; the temperature sensor is quite convenient to use and repair; a power circuit uses a switching power supply so that power consumption of the whole temperature sensor is low; and transmitting distances of output signals of the sensor can be lengthened.

Description

technical field [0001] The invention relates to a mine temperature monitoring device, in particular to a GWD50 coal mine temperature sensor. Background technique [0002] The temperature sensor for coal mine is mainly used to monitor the ambient temperature of coal mine underground. There is a large amount of flammable gas in the underground of coal mine. safety incidents. Therefore, all underground workers need to wear temperature sensors for coal mines or set up temperature sensors for coal mines at fixed points, so that underground personnel can intuitively observe the real-time temperature and provide a certain early warning function. However, most of the temperature sensors used in coal mines today have low sensitivity, cumbersome zero point adjustment, short communication distance, and even no infrared communication function, which greatly reduces the effect of early warning. Contents of the invention [0003] In view of the above problems, the present invention pr...
