Multi-parameter sensor device outside underground shelters

Abstract

The invention relates to a multi-parameter sensor device outside coal mines and non-coal mine underground shelters, which comprises a multi-parameter sensor, a weak signal amplifying module, a master-slave type dual processor module, a communication module, a sensor calibration module, an LCD display module and an explosion-proof shell. The multi-parameter sensor device is installed outside an underground shelter and is used for collecting the concentrations of CO, CO2, CH4 and O2, the temperature and pressure data in real time outside the cabin, and the collected data is transmitted to a monitoring control system of the under shelter through an RS232 / RS485 serial port or a CAN bus interface. The multi-parameter sensor device provided by the invention can be calibrated in an online manner or offline manner and has the work mode of a master-slaver dual processor, so that the stability and the reliability of the device can be ensured. In addition, the LCD display module and the explosion-proof shell can also ensure the convenient and safe operation of the device.

Description

technical field [0001] The invention relates to the technical field of instruments, in particular to a multi-parameter sensor device used for underground shelters in coal mines and non-coal mines. Background technique [0002] At present, methane (CH) is widely used in coal mines and non-coal mines. 4 ) sensor, carbon monoxide (CO) sensor, carbon dioxide (CO 2 ) sensor, oxygen (O 2 ) sensors, temperature sensors and pressure sensors are all independent sensor devices, each sensor device is used to measure the concentration or parameters of a gas, and has LED display function and serial communication port at the same time, these sensor devices are used in the safety monitoring of this field play a huge role in the system. However, for underground shelters that play an important role in underground emergency avoidance systems in coal mines and non-coal mines, there are still the following problems in the application of these sensors: [0003] 1. For underground shelters in...
