In this way, generating low level signal in present embodiment according to high level by signal adjusting module, being equivalent to basis
Rainfall node signal generates a failing edge.In this way, in present embodiment, it, will when rainfall statistical module carries out rainfall statistics
Detection to signal edge is changed into the detection of the momentary switch signal of precipitation rain fall sensor output, is equivalent to and changes transient signal
The possibility that rainfall node signal is failed to report is reduced to advantageously reduce the fault rate of rainfall node signal acquisition for process signal,
Guarantee the acquisition of rainfall node signal accurately and completely, improves the reliability of rainfall statistics.
And in present embodiment, by carrying out delay statistics to signal adjusting module output signal, it is equivalent to rainfall section
Point signal carries out delay Key dithering, is conducive to further increase the accurate of rainfall node signal acquisition, rainfall is avoided to report more.
Acquisition output module is connect with rainfall statistical module, for exporting the rainfall value of rainfall statistical module counts in real time.
In present embodiment, signal acquisition module include with door, adopted with an input pin of door as rainfall node signal
Collection end is accessed high level with the remaining input pin of door, is adopted with the output end of door as signal for accessing rainfall node signal
Collect the output end of module.In this way, in present embodiment, by excessively, be conducive to rainfall node signal of the door to input
Signal acquisition module is further to rainfall node signal Key dithering, to improve rainfall statistics accuracy.
In present embodiment, signal acquisition module further includes the free unit of failure, the first on-off unit and the second on-off list
Member.The output end of first on-off unit and the second on-off unit is all connected with rainfall node signal collection terminal, the first on-off unit and
The input terminal of second on-off unit is respectively used to the first precipitation rain fall sensor of connection and the second precipitation rain fall sensor obtains rainfall node letter
Number.Under first on-off unit on state, the second on-off unit is disconnected.Under second on-off unit on state, the first on-off list
Member disconnects.In this way, by the first on-off unit and the second on-off unit, so that the telemetering terminal can access two rainfall simultaneously
Sensor carries out remote rain amount, improves the failure adaptability to changes of the telemetering terminal.It is logical by first and in present embodiment
Disconnected unit and the second on-off unit, so that two-way rainfall node signal of the signal acquisition module to access, selects one for counting rain
Amount, avoids the mutual crosstalk of two precipitation rain fall sensors, advantageously ensures that the reliable and stable of telemetering terminal work.
The input terminal of the free unit of failure is separately connected the first precipitation rain fall sensor and the second precipitation rain fall sensor, output end point
The first on-off unit and the second on-off unit are not connected.The free unit of failure according to the acquisition data of rainfall node signal for sentencing
Disconnected first precipitation rain fall sensor and the second precipitation rain fall sensor fault condition, and for according to judging result control the first on-off unit and
Second on-off cell operation.In this way, the free unit of failure controls the first on-off unit and disconnects simultaneously when the first precipitation rain fall sensor failure
The conducting of the second on-off unit is controlled, the failure in realization rainfall statistic processes monitors automatically and troubleshooting.Specifically, this implementation
In mode, rainfall node signal of the free unit of failure for being acquired according to the first precipitation rain fall sensor and the second precipitation rain fall sensor
Renewal speed judges the first precipitation rain fall sensor and the second precipitation rain fall sensor fault condition.
Specifically, under natural conditions, the first on-off unit conducting, the second on-off unit disconnects in present embodiment.I.e. originally
In embodiment, based on the rainfall node signal that is imported through the first on-off unit, with the rainfall imported through the second on-off unit
It connects supplemented by electric signal.In this way, both having avoided in rainfall statistic processes, two-way rainfall node signal is frequently replaced, and influences signal biography
Defeated and processing；It when in turn ensuring the first precipitation rain fall sensor failure, can be substituted by the second precipitation rain fall sensor, guarantee that telemetering is whole
The normal work of terminal.
The free unit of failure includes the first timer, the second timer and comparator, and the input terminal of the first timer is used for
The first precipitation rain fall sensor is connected, the input terminal of the second timer is for connecting the second precipitation rain fall sensor, the output of the first timer
The output end of end and the second timer is separately connected the first input end and the second input terminal of comparator, the output end point of comparator
The first on-off unit and the second on-off unit are not connected.First timer is used to calculate adopting recently for the first precipitation rain fall sensor acquisition
The rainfall node signal of collection to current time difference as first time difference, the second timer is passed for calculating the second rainfall
Sensor output recently twice the difference between rainfall node acquisition time as the second time difference.Comparator is used for according to the
The comparison result of one time difference and the second time difference controls the first on-off unit and the second on-off cell operation.Specifically,
In present embodiment, when first time difference is less than or equal to the second time difference, the first precipitation rain fall sensor of expression is worked normally,
Then maintain the first on-off unit on state；When first time difference is greater than the second time difference, the first precipitation rain fall sensor of expression
Failure is unable to normal acquisition rainfall node signal, then is switched to the second on-off unit on state, will pass through the second rainfall biography
Sensor acquires rainfall node signal, guarantees that telemetering terminal works normally.
In present embodiment, by comparator, the rainfall node of the first precipitation rain fall sensor and the second precipitation rain fall sensor is believed
Number frequency is compared in real time, is advantageously ensured that the accurate of the first precipitation rain fall sensor breakdown judge.
In present embodiment, it is in series with adder between comparator and the second timer, comparator is by the second time difference
With adder access floating difference summation be used as reference point, comparator be used for according to first time difference compared with reference point knot
Structure controls the first on-off unit and the second on-off cell operation.Specifically, comparator is used to be greater than reference in first time difference
When value, the first on-off unit of control disconnects and controls the conducting of the second on-off unit.The setting of adder, in first time difference and
Floating difference is introduced between second time difference, is conducive to keep away while guaranteeing accurately to monitor the first precipitation rain fall sensor failure
Exempt from unstable caused by the first on-off unit and the second on-off unit frequent switching working condition.Specifically, the first on-off unit
Relay is all made of with the second on-off unit.
