Abstract

The invention relates to a multi-parameter sensor for a transition chamber, which includes a plurality of sensors, a weak signal amplification processing module, a master-slave processing module, a communication module, a display module, a calibration module and a shell structure. The present invention can be installed in the transition cabin, collect CO, CO2, CH4, O2 gas concentration data in the cabin in real time, and transmit them to the monitoring and control system of the mobile rescue cabin and the fixed refuge chamber through the RS232/RS485 serial port and the CAN bus interface. The calibration of each sensor has two ways: online calibration and offline calibration. The zero point and range of CO, CO2, CH4, O2 can be calibrated at one time, and the parameters of the weak signal amplification processing circuit can also be calibrated. The master-slave processing module ensures the stability of the present invention. High performance and reliability, the display module and the explosion-proof structure shell make the operation convenient and safe. It solves the problem of installing multiple sensors and data transmission interfaces in the limited space of the transition cabin in the underground mobile rescue cabin of the mine.

Description

technical field [0001] The invention relates to the technical field of instruments, in particular to a multi-parameter sensor for a transition cabin of an underground mobile rescue cabin (or a fixed refuge chamber) in coal mines and non-coal mines. Background technique [0002] Currently, 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 are all independent sensors, each sensor device measures a gas concentration, has LED display and serial communication port, and plays a huge role in the safety monitoring system in this field. However, there are the following problems in the application of mobile rescue cabins and fixed refuge chambers that play an important role in underground emergency avoidance systems in coal mines and non-coal mines: [0003] 1. Multiple sensors need to be properly installed in a limited space, and the cost is high. [0004] 2. The number of se...
