POSITIVE PRESURE TYPE GAS SAMPLE COLLECTOR AND SYSTEM FOR OPERATING IT WITH RADIO FREQUENCY

摘要

A positive pressure-type gas sample collector and an operation system thereof using wireless communication are provided to check the collecting state of a collecting bag in real time by mounting the collecting bag outside without keeping an internal vacuum condition. A positive pressure-type gas sample collector comprises a gas intake pipe(21), a flow rate control valve(22), a gas pump(23), a manifold(24), at least one solenoid valve(25), a microprocessor(27), a case, and at least one collecting bag(26). The gas intake pipe is installed to intake a gas sample. The flow rate control valve is mounted to control the quantity of gas passing through the gas intake pipe. The gas pump provides intake pressure to the gas intake pipe at one side and discharge pressure at the other side. The manifold is formed with an inlet receiving the gas sample discharged from the other side of the gas pump, and at least one outlet outputting at least one passage. The solenoid valve is mounted to open and close the outlet. The microprocessor controls the operation of at least one of the flow rate control valve, the gas pump, and the solenoid valve. The case is mounted with at least one of the gas intake pipe, the flow rate control valve, the gas pump, the manifold, the solenoid valve, and the microprocessor inside. The collecting bag is connected to each outlet of the manifold at an outside of the case to keep the gas sample.
