Upper computer module 800, you can, can on the screen of upper computer module 800 directly to send out the computer of manipulation command When showing that the gas concentration of each road gas sampling assembly acquisition and the data and modules of acquisition time work, the The signal intensity situation of one vapor sensor 2,3,4 and the second vapor sensor 5 and electronic flowmeter 17.Upper computer module 800 major functions for including have:The signal message for receiving signal transmission module 600, carries out the reading of signal data, shows and deposit Storage, carries out the analysis of data, is acted come starting device remote control module 731 by human-computer interaction interface 840 and passes through early warning Function module 841 carries out warning function.After signal transmission module 600 receives coherent signal, by the reading of data, deposit Storage can show the concentration data and gas signal and water-flow signal of gas on the screen of upper computer module 800 Mutual transitional information determines the action and instruction of next step by data analysis, includes whether to start aspiration pump 13 and row Air pump 14 and selection start gas detection function or drain function.By data analysis, after obtaining corresponding conclusion, make It transmitted between people and computer, exchange information media and the human-computer interaction interface 840 of dialog interface is then remotely controlled by equipment Molding block 731 carrys out the realization of the next step action and function of control device, and then equipment remote control module 731 then passes through signal Transmission module 600 instructs the next step of equipment to act to the signal of corresponding equipment sending action.Meanwhile when equipment is remotely controlled Molding block 731 receives the chamber door that mechanical stroke switch is sent and is opened, i.e., when integrated equipment is in the signal of abnormality, Human-computer interaction interface 840 can directly initiate warning function module 841, to achieve the purpose that timely early warning and debugging.Cause This, the process of entire signal transmission is actually the process of a feedback, and signal transmission module 600 then plays communication and tie Effect.
The signal transmission structure of the present embodiment is as shown in figure 8, the solid arrow in figure is output side signal to dotted arrow Direction is fed back for signal, is respectively present between upper computer module 800, signal transmission module 600 and circuit control panel 710 two-way Data signal transmission stream, circuit control panel 710 and gas collecting module 100, power plant module 300, drain module 300 and power supply Two-way data signal transmission stream is respectively present between 720, and gas preprocessing module 200 and gas detection module 500 are distinguished There are the outputs of unidirectional data-signal to flow between circuit control panel 710.
The present embodiment also proposed the control method of gas concentration detector as described above, include the following steps:
S1, gas in each inspection shaft is acquired respectively by the gas collecting channel of multi-channel parallel;
S2, gas-water separation pretreatment is carried out to the gas of acquisition by gas preprocessing module;
S3, pretreated gas is detected by gas detection module 500, to obtain the data information of gas;
S4, by the data information of control system analysis gas, to judge whether gas pipeline leaks;
S5, judging result is shown by control system, and pre- according to judging result adjustment gas collecting module 100, gas Processing module 200 and gas detection module 500.
Specifically, when carrying out gas detection function using the gas concentration detector, it is first turned on gas-monitoring hardware The power supply of system and control system, module 743 to be verified terminate checking routine, the signal that equipment can work normally are passed through letter Number transmission module 600 is transferred to after equipment remote control module 731, and equipment remote control module 731 passes through circuit control 710 order aspiration pump 13 of plate is in negative pressure working condition, and gas collecting module 100 is extend into inspection shaft to the gas acquired in inspection shaft Body, air-flow to be measured can sequentially pass through gas sampling assembly 1-1,1-2 is sought in filtering and enter gas by the solenoid valve 1 of circuit control In acquisition module 100, by circuit control, multipath electrovalve 1 has multi-channel sampling mouth free switching function.It is pre-processed in gas In module 200, air-flow is in the mistake for flowing through the moisture separator 6,7,8 that three work normally under low discharge and low-pressure state Cheng Zhonghui removes the aqueous water in air-flow, and under the control of circuit, the first water flow sensing unit 2,3,4 passes through signal transmission respectively Module 600 is kept at any time and the data exchange of equipment remote control module 731, passes through the second water flow sensing unit 5 to reach air-flow There is no the purpose of aqueous water, realization to automatically cut off gas preprocessing module when the second water flow sensing unit 5 is intake in Shi Chengfen Gas treatment channel function and it is anhydrous when keep the pipeline in gas treatment channel unimpeded function.
In gas treatment channel, under test gas, which enters by check-valves 11 in drier 12, further removes moisture, later Abundant dewatered air-flow then enters in gas detection module 500, and the gas for flowing through pipeline is controlled by spinner flowmeter 15 Body flow is to meet range appropriate, and electronic flowmeter 17 can then be monitored flow, spinner flowmeter 15 and electron stream Gauge 17 transmits data on flows by signal transmission module 600 under the control of circuit to equipment remote control module 731 respectively. Then, the gas of certain flow carries out the toxic and harmful gas concentration such as methane and ethane by combustible/toxic gas sensor 16 Test, to achieve the purpose that in inspection shaft that gas concentration detects, meanwhile, combustible/toxic gas sensor 16 and signal transceiver 18 connections can transmit the concentration data of gas under the control of circuit by signal transmission module 600 to control system, and The type, concentration and time of gas are corresponded;Gas concentration detection is discharged by exhaust outlet 21 in gas after detection Instrument.
When gas detection module 500 is intake, i.e., when gas detection function cannot be realized normally, equipment remote control module 731 in receiving the second vapor sensor 5 after having signal existing for moisture, can be ordered and be taken out by circuit control module 700 Air pump 13 is closed, while order draining pump 14 is opened, and simultaneously closes off multipath gas acquisition channel by solenoid valve 1;It is arranging Under the action of water pump 14, gas passes through three moisture separators 6,7,8, the water that will be deposited in three moisture separators 6,7,8 successively It is respectively pressed into drain module 400, after check-valves 9,10 and the second vapor sensor 5, is discharged by discharge outlet 20.
It should be noted that between gas detection module 500 and signal transmission module 600 and signal transmission module 600 Can be connected by communication between control system, including but not limited to wired, wireless, 3G signals, 4G signals with And the communications such as GDB network modes.
