It is smoothed out.
When rainfall runoff intellegent sampling device is applied, it is necessary first to its mode of operation is configured, in different modes,
It is also different to sample flow.
Workflow under water level (or flow) inductive mode：Water level (or flow) probe is in real time to the water in sampling terminal
Position (or flow) parameter measures, once catchment occurs, and samples the water level in terminal (or flow) and exceedes threshold value
After index, control system is sampled evacuation system collection is started, and equipment comprises the following steps that：
Step 1：Water system air is received to exclude.Total valve, branch pipe valve opening；Remaining branch pipe valve is closed, starting mode of pump
Continue 5~10s, the pipeline space received in water system is completely filled with rainwater sample.
Step 2：Rainwater sample is injected into sampling bottle.Water pump remains in operation 5~10s, it will fill 1 in No. 1 sampling bottle~
1.5L rainwater sample, water pump shut down.
Step 3：Water system rainwater sample is received to empty.Water pump is inverted under control system effect, and water will be received by continuing 5~10s
The rainwater sample of system is rejected in sampling terminal, to avoid the sample production of rainwater sample and second of sampling process in pipeline
Raw melange effect, completes No. 1 sampling bottle sampling process.
System will carry out second of sampling process according to default setting or pre-set programs after standby certain time.Due to water
Position (or flow) sensor distance 1min, the water level value (or flow value) of meeting real-time detection sampling terminal.If water level (or stream
Amount) be constantly in the state more than threshold value index, then the continuous repeat step 1~3 of this sampling process, is sampled until No. 2~No. 12
Untill bottle takes completely completely.Whole sampling process duration are according to program setting；After if rain time stops, sampling in terminal
Water level value (or flow value) be less than threshold value index, sampling process will terminate automatically, and control system will close total valve.
Workflow under command mode：This pattern be sampler at the scene, by manual operation control key form, to control
The parameters such as startup time of system processed, sampling time, interval time are configured.System works as shown in step 1~3.Sampling
During, water level (or flow) parameter in sensor assembly time real-time perception sampling terminal, if measured value refers to less than threshold value
Mark, sampling process will terminate automatically.
Workflow under mobile terminal remote control model：This pattern be sampler not at the scene, but obtain, sampling
Rainfall runoff event occurs for region, will start the parameters such as time, sampling time, interval time and is sent to control by short message mode
System, control system receive short message by movable signal receiving module, and information is read as control instruction by mode control module, right
The systems such as water pump, magnetic valve are controlled, and complete sampling process.In sampling process, the sampling of sensor assembly meeting real-time perception is eventually
Water level (or flow) parameter in end, if measured value is less than threshold value index, sampling will terminate automatically.
