Individual magnetic valve is with feedback signal (reaching a feedback signal, close feedback signal in place), it is ensured that only corresponding logical during gas collecting
The magnetic valve in road is opened, and as control instruction is inconsistent with feedback signal, then turns off aspiration pump, be stopped simultaneously fault alarm.
Gas production flow of the controller mainboard to the flowmeter on gas production loop measures, and gas production loop flow passes through number
Pipe shown, judges the work of gas production flow whether in normal range of operation, such as occur magnetic valve do not open, aspiration pump not work
The unusual conditions such as work, stop pumping pump work, upper master is uploaded to by numeral method failure code, and by failure code
Machine.
Controller mainboard is clearance-type working method, and upper main frame sends an acquisition instructions in about 6 hours, and control mainboard connects
After receiving upper host command, 8 way solenoid valves are switched over respectively, different cabin gas collectings is carried out, currently gathers position
Shown by a digital green Guan Shihang, and current collection positional value is uploaded to upper main frame.8 passages have gathered successively
Afterwards, control mainboard enters wait state, waits the acquisition instructions of upper main frame next time.
After each switching solenoid valve of controller mainboard, residual gas in the pipeline of existing collection cabin need to be emptied, control mainboard
It is preprocessed state to transmit to the amount of acquisition channels value of upper main frame, and switching solenoid valve is after 2 minutes (gas in pipelines has emptied), control
It is acquisition state that mainboard processed, which is transmitted to the amount of acquisition channels of upper main frame, and the amount of acquisition channels is true with mass spectrograph communication acquisition for upper main frame
Real collection value.
