Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of automatic control multipoint mode acquires switching system, including data acquisition and monitoring system 1 and logical
The hub 3 that fiber optic network 2 is connect with data acquisition and monitoring system 1 is crossed, the hub 3 is separately connected PLC4, ginseng
Number setting computer 5 and gas analyzer 6；For the gas analyzer 6 including multiple, each gas analyzer 6 passes through switching
Device 11 is connected to one in more sampling pipes 12, and the switch 11 is connect with PLC 4, and the PLC 4 receives data acquisition
And monitoring system 1 instructs and controls switch 11 and switch different sampling pipes 12 and sampled, gas analyzer 6 divides sample
It is shown after analysis by analysis device displaying result 10 connected to it；
More specifically, it is provided with suction pump 8 between the sampling pipe 12 and gas analyzer 6, for taking out to gas
It takes, flowmeter 9 is provided between the suction pump 7 and switch 11, the flowmeter 9 is connect with PLC4, for passing flow
It is defeated by data acquisition and monitoring system 1；
More specifically, the other side of 11 relative jam of the switch pump 8 is communicated with bypass suction pump 7, and the bypass is taken out
Sucking pump 7 is connect with PLC4, for keeping the air circulation of other test points outside test point in switch, and in test point switching
It can switch over, guarantee the smoothness of switching.
Concrete function is described below:
1, customized MANIFOLD 2-100CHANNELS is available
2, each analysis instrument is integrated into 19RACK, can shows analysis readings simultaneously
3, the acquisition of scene collocation data and monitoring system (LOCAL SCADA) PC can pass through fiber optic network for monitored picture
It is sent to Central Control Room
4, man-machine interface can be according to field demand higher sampling measurement mode sampling order online
5, picture control picture can be according to user's sets itself bound & parameter setting, and provides alarm and history number
According to function
6, PLC module and figure control software, which do Conformity planning, can set sampling signal starting, and secondary signal can drive sampling immediately
Device carries out air sample sampling.
7, switch-can customized each shop of setting different sampling time
8, every set configures (pump) PUMP and BY PASS PUMP bypass pump, with when the different sampled points of sharp sampling not
Pollution mutually
9, increase electronic flowmeter, monitor SAMPLE flow in real time
10, sampling pipe uses PTFE/PFA/FEP, and avoidable sampling pipe is lost, polluted
11, instruction is sent by computer when working and stops PLC, is executed instruction by PLC, operating measurement gas is driven by pump, from
And it is transmitted to gas analyzer, then analysis data are intuitively seen by computer.Again by the pressure in BY PASS PUMP holding group machine
Power, to guarantee the smoothness of switching.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
