Terminal sends sampled signal to the remotely control processing module, makes airbag be sampled；After the completion of sampling, system is automatically stopped
Sample, and sampling ending message is sent by remotely control processing module and inform that sampling terminates to sample collector's control terminal.
As shown in Fig. 2 measure-controlling unit includes the monitoring, alarming signal processing module, solenoid valve control module and adopts
Sample pump control module, the solenoid valve control module are electrically connected with to control with two three-way electromagnetic valve and two-bit triplet electromagnetic valve
Air circuit breaker or switching, the sampling pump control module are used for the on/off for controlling the sampling air pump.
Preferably, measure-controlling unit can also include remotely control processing module, remotely control processing module for
PCT communicates, and to receive the instruction that outside foul smell gathers beginning and end, controls the switch of the electromagnetic valve or cuts
Change.
Preferably, measure-controlling unit includes a pressure measuring module, the pressure measuring module and the pressure transducer
It is electrically connected with, to the measurement data for receiving and processing the pressure transducer.
Preferably, measure-controlling unit includes operating Display processing module, is connected with other modules of measure-controlling unit,
To arrange Instrument working parameter and show other module status or process other module corresponding functions.It is corresponding to have one outside
The host service function screen 3 that can be shown and operate.
In the present embodiment, each functional module of measure-controlling unit all can be integrated in a SOC(system on a chip).
As shown in figure 3, being the typical workflow diagram of the sampling apparatuses.
First operationally, instrument is started shooting, then can arrange instrument carries out airbag cleaning, then by monitoring, alarming
To density real-time monitoring alarming signal processing, whether monitoring concentration exceedes given threshold to signal processing module, continue if not into
Row monitoring, if exceeded, automatically control electromagnetic valve and sampling air pump work by measure-controlling unit, carries out foul smell sampling.
When sample is completed, electromagnetic valve sealed air pocket is closed, note remote notification sampling engineer terminates sampling.
Another mode of operation is to send startup sampled signal by control terminal and start to remotely control processing module
Sample collecting is carried out, the sampling of system automatic decision is completed and terminates sampling.
