And meanwhile, the cloud end is connected to obtain the organic matter content at the beginning of collection, and the predicted value of the lifting gas weight can be calculated according to the gas volume. And dividing the predicted value of the gas weight subtracted by the predicted value of the gas weight by multiplying the predicted value of the gas weight by 100%, judging that the collecting state is normal when the result is less than 23%, and outputting the content of volatile organic compounds in the atmosphere according to the gas weight value and the total weight of the trapped gas. And when the result is more than or equal to 23%, judging that the collecting state is abnormal, stopping the operation of the condensation trapping device by the system to alarm, packaging error reports of all the components together, and sending the error reports to a monitoring platform to allow people to participate in investigation.
