Technical field
The present invention relates to automobile technical field, and more particularly to a kind of stay-supported type displacement sensor demarcation and check device
With demarcation, check method.
Background technology
In vehicle and sled test, sensing in knee displacement transducer data failure or process of the test often occurs
The phenomenon that device is damaged, such case can lead to not confirm the huckle in C-NCAP (Chinese new car assessment routine) management rule
The high-performance limit value and low performance limit value of the knee slide displacement that position scoring is required, so influencing whether the scoring at thigh position.
For the knee displacement transducer data failure phenomenon occurred in vehicle and sled test, timely core is needed after experiment
Look into data failure reason.The method of currently used verification sensor data failure is：First carried out using G5 data collecting instruments
Static Detection, checks whether that all of parameter all passes through.Then using G5 data collecting instruments " realtime " function and coordinate
Ruler, whether the pull-out amount of display is consistent with the size that the pickup wire measured on ruler is pulled out in real time to check sensor.But should
Method is larger by man's activity, when pulling out pickup wire, can there is the next error of tilting band or imprudence is loosed one's grip will pass suddenly
Sensor line is put back to, and causes sensor to damage.
On the other hand, required in C-NCAP management rules：A coming half year should be done after every 2 experiments of dummy's knee joint slide displacement
Between verify, but number of sensors is more, and detection number of times is more frequent, very inconvenient using existing detection method.And, make
When carrying out Static Detection with G5 data collecting instruments, if not detecting the problem of sensor, and the data exception of sensor, such one
As cannot confirm the linearity of the sensor whether in claimed range, so calibration will be sent to, but existing calibration method
Not only the time is long, and costly.

Further, the demarcation of stay-supported type displacement sensor and check device are a block structure, and survey mass is to be formed at
Rectangular-shape survey mass in block structure, relative with the side another side of survey mass is in the same plane.
A kind of demarcation for utilizing stay-supported type displacement sensor as described above and check device are verified, the side of calibration sensor
Method, comprises the following steps：
Data acquisition software is opened, and opens the sensor voltage calibrating function of software；
Sensor is drawstring through draw-in groove, sensor is close to the demarcation of stay-supported type displacement sensor and check device
The cell wall of draw-in groove is close in bottom surface, the bracing wire of sensor, and the other end of bracing wire is stuck in the top surface of draw-in groove；
On observed data acquisition software in real time display bracing wire length data whether the demarcation with stay-supported type displacement sensor
And the design draw-in groove of check device is highly consistent, while reading each corresponding voltage of bracing wire length that software interface shows, lead to
Cross and be linearly calculated the sensitivity for being calibrated sensor and the linearity.
In sum, the right side wall of draw-in groove 2 is close to due to pickup wire, sensor is close to stay-supported displacement sensing
In the demarcation of device and the same bottom surface of check device, therefore present invention may determine that the length of the pickup wire for pulling out every time is all
Stablize and equal, and multi-group data can be pulled out during experiment and checked one by one, reduce once in a while once the appearance of pull-out amount
Error and cause mistake judgement, while reduce artificial origin to sensor cause damage possibility.
