Mechanical measurement structure measurement and by sensor export measurement data be modified, so as to can to measurer manufacture in error
Effectively corrected, so improve production efficiency, while reducing production cost and also high-precision measurement demand being met.
Description of the drawings
Fig. 1 is the structured flowchart of digital display appliance of the present invention.
Specific embodiment
Describe the present invention below with reference to each embodiment shown in the drawings.But these embodiments are not
Limit the present invention, structure, method or change functionally that one of ordinary skill in the art is made according to these embodiments
Change and be all contained in protection scope of the present invention.
Incorporated by reference to shown in Fig. 1, digital display appliance of the present invention includes mechanical measurement structure and is fixed to the mechanical measurement structure
On with export mechanical measurement structure measurement data output device.The output device includes connecting with the mechanical measurement structure
It is the sensor that connects, the display of the digital measuring circuit module of connection sensor and digital measuring circuit module connection, defeated
Enter module and be connected between the digital measuring circuit module and display to enter with the measurement data to mechanical measurement structure
The processor of row correcting process.The measurement data pre-set with actual measurement to sensor is preserved in the processor
It is modified the adjusted value of process.The input module includes the operation keyboard for being arranged at display side to be operated.Institute
State operation keyboard to be electrically connected with processor.The digital display appliance also includes the power supply of the connection processor.The machinery is surveyed
Amount structure can be micrometer, slide calliper rule, amesdial or other length-measuring appliances etc..
Digital display appliance of the present invention measures the method for data correction and comprises the steps,
First, the mechanical measurement structure is moved to into zero point, and the machinery is recorded within a processor by input module
When measurement structure is in zero point, sensor is exported to zero point measurement data x0 and real null value y0 of processor；
Then, mechanically moving measurement structure, and mechanical measurement structure is recorded within a processor in each by input module
Measurement data xn of sensor during sampled point yn, while the actual value of each sampled point is detected using a standard gauge block
Yn ', and by actual value yn of each sampled point ' is corresponded with measurement data xn of sensor and is stored into processor；
Finally, processor is to each measurement data xn and actual value yn ' sampling intersection point（xn, yn’）With zero point (x0,
Y0 linearization process is carried out respectively), while according to the sampling intersection point（xn, yn’）With the line of zero point (x0, y0) rat tail
Bar attribute obtains the adjusted value that is modified to the measurement data of sensor and stores, with using the adjusted value to measuring
Measurement data in journey is modified.
For example, during the manufacturing of digital display appliance, there are a calibration process, at this moment, operator（It is not shown）
Mechanical measurement structure is moved to into zero point first, and the measurement data of the sensor of zero point is recorded by input module notifier processes device
X0, while actual value y0=0 of corresponding record zero point；Then, mechanically moving measurement structure is to sampled point y1, while record exists
Measurement data x1 of sensor during sampled point y1, reuses actual value y1 that standard gauge block detects the sampled point ', and pass through
Input module is by actual value y1 ' input processor be sampling intersection point by data record（x1, y1’）；Finally, process
Device will be sampled intersection point according to embedded software algorithm（x1, y1’）With zero point（x0, y0）Draw a straight line, straight line it is oblique
Rate represented with k1, it can thus be appreciated that：y1’-y1=k1*(x1-x0)；And the y1 ', y0, x0, x1 in formula is datum, can obtain
k1=( y1’-y1)/(x1-x0)；Hence for any point y1=y0+k1* (x1-x0) on the straight line, i.e., processor can
It is modified to obtain the true measured value of object under test using measurement data x1 at 1 pair of y1 point of the slope k.I.e. at this
In embodiment, the slope k 1 is processor and repaiies to the output measurement data of the sensor to digital display appliance of the present invention
Positive adjusted value.In the above-described embodiment, sampling intersection point（x1, y1’）With zero point（x0, y0）Between with straight line connect,
And with the slope k 1 of the straight line as adjusted value carrying out the corrected Calculation of actual measurement data；Really, it is in other enforcements, described
Processor can be also arranged by using 2 curves or 3 curve connections, so as to being calculated and be obtained using 2 times or 3 curve matchings
The adjusted value that can be modified to the measurement data of sensor output is taken, and then allows digital display appliance of the present invention to export essence
True measurement data.
The measuring method of digital display appliance of the present invention is comprised the following steps,
First, using mechanical measurement structure to an object under test（It is not shown）Measure；
Secondly, sensor receives measurement data and measurement data is passed to processor by digital measuring circuit module；
Then, processor is modified to the measurement data that sensor is measured according to the adjusted value for prestoring, and will be repaiied
Measurement data after just sends display to；
Finally, display receives revised measurement data and carries out output display.
In sum, digital display appliance of the present invention passes through internal processor, thus using the embedded software of the processor
Algorithm obtains the adjusted value that frame for movement error or other rigging errors to the digital display appliance are modified compensation so that this
The measurement data that bright digital display appliance can be exported to mechanical measurement structure measurement and by sensor is effectively corrected, and then improves life
Efficiency is produced, while reducing production cost, and also high-precision measurement demand can be met.
