Immersion, then be shorted between two conducting polymers, and makes surveyed current value change, and surveys so as to be caught by water leakage controller
Measure these electronic signals.Generally controller can be monitored up to (accurately effectively) 100 meters or so of the leakage line of induction.Once detection
To liquid, controller shows and trigger relay controls ancillary equipment.Generally led to by RS485 interfaces and monitoring system
Letter, controller can not only be used for the leak detection alarm unit of isolated operation and use, and also can make with other integrated collection main frame networkings
With.But this water-leakage detecting system is occurred and is not occurred using the one-dimensional judgement based on point with leak, i.e., " leak " and " not leaking "
Based on carry out signal judgement, belong to alert category afterwards, especially for high precision machine room, communication base station equipment pacify
Full hidden danger management can not give a forecast processs, and easily cause warning information by the one-dimensional detection of single-point and report by mistake, therefore can not
The completely safe operation of guarantee equipment.And this leak system can be related in implementation process comprehensive wiring, warning distance,
The problems such as positioning, networking, is limited by machine room geographical environmental condition and causes high cost, safeguards that threshold is high.

Device, the network controller adopts W5200 Module-embedding formula TCP/IP ethernet interface modules, by SPI interface and central authorities' control
Device connection processed；The central controller connects mobile terminal or PC ends by network controller.
7. a kind of pipeline realized based on claim 1 described device joins pipe fitting leakage detection method, it is characterised in that step
It is as follows：
S1, four rain sensors gather respectively signal, and are respectively transmitted to central controller；
S2, the analog signal I/O port of central controller receive rain sensor A, rain sensor B and rain sensor C and adopt
The analog signal of collection, and the analog signal of rain sensor A, rain sensor B and rain sensor C currently collection is judged respectively
Whether correspondence amount of rainfall parameter value is in infiltration scope or has water scope；Simultaneously the data signal I/O port of central controller connects
The data signal of rain sensor D collections is received, and judges whether the data signal that rain sensor D is currently gathered is infiltration letter
Number；The amount of rainfall of the wherein simulated reflected signal that central controller is gathered according to rain sensor determines an amount of rainfall parameter value
Scope, then determines infiltration scope to the impact that pipeline joins pipe fitting from amount of rainfall range of parameter values and has water according to amount of rainfall
Scope；
S3, the signal determination currently gathered according to rain sensor A, rain sensor B, rain sensor C and rain sensor D
Pipeline joins the corresponding state of pipe fitting, and central controller controls Alarm Unit is alerted accordingly：
When the data signal of rain sensor D currently collections is infiltration signal, then judge pipeline handing-over pipe fitting in infiltration shape
State, central controller controls Alarm Unit carries out infiltration alarm；
When rain sensor D currently collections data signal for non-infiltration signal when, and rain sensor A, rain sensor B or
When the analog signal correspondence amount of rainfall parameter value of rain sensor C currently collections is in infiltration scope, then pipeline copulatory tube is judged
Part is in infiltration state, and central controller controls Alarm Unit carries out infiltration alarm；
When rain sensor D currently collections data signal for non-infiltration signal when, and rain sensor A, rain sensor B and
Analog signal correspondence amount of rainfall parameter value of rain sensor C one of them current collection then judges pipe in when having water scope
Road handing-over pipe fitting is in dampness, and central controller controls Alarm Unit carries out moist alarm；
When rain sensor D currently collections data signal for non-infiltration signal when, and rain sensor A, rain sensor B and
The analog signal correspondence amount of rainfall parameter value of rain sensor C two of which currently collection then judges pipe in when having water scope
In there is water state, central controller controls Alarm Unit has carried out water and has alerted road handing-over pipe fitting；
When rain sensor D currently collections data signal for non-infiltration signal when, and rain sensor A, rain sensor B and
When the analog signal correspondence amount of rainfall parameter value of rain sensor C currently collections has been in water scope, then judge that pipeline joins
Pipe fitting is in infiltration state, and central controller controls Alarm Unit carries out infiltration alarm.
8. pipeline according to claim 7 joins pipe fitting leakage detection method, it is characterised in that in step S2,
Ambient humidity around humidity sensor collection pipeline copulatory tube part, and is sent to central controller, central controller according to
Humidity is to the corresponding amount of rainfall parameter value of the analog signal of rain sensor A, rain sensor B and rain sensor C currently collection
It is adjusted：When humidity is more than 60%RH and less than or equal to 70%RH, by rain sensor A, rain sensor B and rainwater
The analog signal correspondence amount of rainfall parameter value of sensor C currently collections reduces x；When humidity is more than 70%RH, rainwater is passed
Sensor A, rain sensor B amount of rainfall parameter value corresponding with the analog signal of rain sensor C currently collections reduces 2x.
9. pipeline according to claim 7 joins pipe fitting leakage detection method, it is characterised in that at pipeline handing-over pipe fitting
When the state of infiltration, buzzer, the first LED light and the first bulb work in central controller controls Alarm Unit,
When pipeline handing-over pipe fitting in have water state when, the buzzer of central controller controls Alarm Unit, the second LED light and
Second bulb works, and when pipeline handing-over pipe fitting is in dampness, controls buzzer, the 3rd LED light of Alarm Unit
And the 3rd bulb work；When wherein pipeline joins pipe fitting in dampness, under having water state and infiltration state, buzzer work
Tone increase successively.
10. pipeline according to claim 8 joins pipe fitting leakage detection method, it is characterised in that network controller passes through
W5200 module constructions network WEB is serviced, and central controller is with the frequency per second by rain sensor A, rain sensor B, rainwater
Sensor C, rain sensor D and the signal of humidity sensor collection pass to PC ends or with XML file side with html page
Formula passes to mobile terminal.
