Remote gas monitoring system and method

The present invention provides a system and method for remotely monitoring a gas, the gas monitoring system comprising: at least two detection units, each detection unit includes a sensor, a memory, a processor; output signal of said processor via a first transmission network to the processing unit, the anti-cross talk within the parameter memory Aji transmitted through the network to the second processing unit, i = 1,2,3 ... N, N≥2, N is at least partially in the environment under test gas species number; a processing unit, the processing unit receives the output signal of an anti-crosstalk parameters Aji, Kj so as to obtain the type and content of the gas to be measured, and transmitted to the transmitting unit; transmitting unit, the transmitting unit with to the type and content of the received test gas transferred through the third network to the monitoring platform. The present invention has an anti-cross interference, detection accuracy, maintenance, and low power consumption.
