Problems solved by technology
In order to effectively prevent accidents, mine-used intrinsically safe temperature sensors are installed underground. When the temperature exceeds a fixed value, the external temperature signal is transmitted to the host, which will remind people to take preventive measures quickly. Generally, the temperature detection of stationary objects Relatively easy, but there are relatively few temperature testing methods for equipment that is moved or adjusted for operation
[0003] In addition, the current mine-used intrinsically safe temperature sensors all have an alarm function, but most mine-used intrinsically safe temperature sensors are relatively lagging in induction, and the time to respond to changes in temperature is also relatively lagging

Description
technical field [0001] The invention relates to the field of intrinsically safe infrared temperature sensors for mines, in particular to an intrinsically safe infrared temperature sensor for mines with frequency signal output. Background technique [0002] At present, most coal mines in my country are full of methane and coal dust explosions. When the underground ambient temperature reaches a certain value, in the case of sufficient oxygen, methane and coal dust will burn or even explode, causing major safety accidents. In order to effectively prevent accidents, mine-used intrinsically safe temperature sensors are installed underground. When the temperature exceeds a fixed value, the external temperature signal is transmitted to the host, which will remind people to take preventive measures quickly. Generally, the temperature detection of stationary objects Relatively easy, but for equipment that is moved or adjusted for operation, there are relatively few temperature testin...
