Description
Technical field
The utility model relates to the detection device of aviation instrument, specifically a kind of aviation alternating voltage output transducer
Signal supervisory instrument is primarily adapted for use in detection and records the impacted situation of change of sensor output AC signal, and passes through
The performance indicator of data assay sensor.Its IPC code is G01R19/00.
Background technique
Currently, the well known detection device for alternating voltage output sensor signal is multimeter or A.C. voltmeter.
Its testing principle is that ac signal is converted into direct current signal using the method for rectifying and wave-filtering to be then acquired quantization, due to
The presence of filter circuit also by abnormal interference signal while filtering out while alternating component in filtering out signal, therefore can not
Indicate whether sensor output signal fast jitter is abnormal signal.And then lead to the missing inspection of bad sensor, give detection inspection
It repairs and brings inconvenience.
Utility model content
In order to overcome the shortcomings of existing apparatus, the missing inspection of bad sensor is avoided, the utility model provides a kind of aviation
Alternating voltage output sensor signal detection device, on the basis of not influencing AC signal voltage measurement function, moreover it is possible to detect
With record sensor output signal wobble variation situation, and can check repeatedly detection data record, to more accurately analyze
Judge the use state of sensor.
To achieve the above object, the utility model provides following technical solution: the experimental rig includes communication interface electricity
Road, the single-chip microcontroller that communication interface circuit connecting pin is set and signal conversion module and data that single-chip microcomputer input is set
Memory module is characterized in that: signal conversion module includes that the analog-digital converter being arranged on single-chip microcontroller and single-chip microcontroller input
The connected circuit for generating synchronous signals in end and signal peak follow circuit.
The utility model has the beneficial effects that by using the analog-digital converter, defeated with single-chip microcontroller by being arranged on single-chip microcontroller
Enter the signal conversion module that the connected circuit for generating synchronous signals in end and signal peak follow circuit to constitute, effectively prevents nothing
Method judges the drawbacks of whether sensor output signal fast jitter is abnormal signal, so that the detection for improving sensor is accurate
Degree.The periodic signal synchronous with measured signal is generated by circuit for generating synchronous signals and passes to single-chip microcontroller, single-chip microcontroller is according to synchronization
Signal generation controls peak value follower circuit for the control signal that signal follows, and carries out to each wave crest of input exchange signal
It follows holding and is sent into the ADC built in single-chip microcontroller and be acquired, collected each peak-data is recorded in memory, passes through
The record data of each period required for communication interface circuit is spread out of carry out observation analysis.
