Description of drawings
Fig. 1 is the structured flowchart of the utility model digital display appliance.
Embodiment
Below with reference to each embodiment shown in the drawings the utility model is described in detail.But these embodiments do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in the protection domain of the present utility model.
Please in conjunction with shown in Figure 1, the utility model digital display appliance comprises the mechanical measurement structure and is fixed on the described mechanical measurement structure output unit with the measurement data of output mechanical measurement structure.Described output unit comprises digital measurement circuit module, the display, the load module that are connected with described digital measurement circuit module of the sensor that is connected with described mechanical measurement structure, connecting sensor and is connected between described digital measurement circuit module and the display the measurement data of mechanical measurement structure is carried out the processor of correcting process.Preserve in the described processor and set in advance the measurement data of sensor to be carried out when the actual measurement adjusted value of correcting process.Described load module comprises and is arranged at the operation keyboard of display one side to operate.Described operation keyboard and processor are electrically connected.Described digital display appliance also comprises the power supply that connects described processor.Described mechanical measurement structure can be milscale, slide calliper rule, clock gauge or other length-measuring appliances etc.
The method that the utility model digital display appliance carries out the measurement data correction comprises the steps,
At first, described mechanical measurement structure is moved to zero point, and sensor is exported to the measurement data x0 and real null value y0 at zero point of processor when recording this mechanical measurement structure be in zero point in processor by load module;
Then, mechanically moving is measured structure, and the measurement data xn of the sensor when in processor, recording the mechanical measurement structure and be in each sampled point yn by load module, utilize simultaneously a standard gauge block to detect the actual value yn ' of described each sampled point, and with the measurement data xn of the actual value yn ' of each sampled point and sensor one by one corresponding stored to processor;
At last, processor is to the sampling intersection point (xn of each measurement data xn and actual value yn ', yn ') with (x0 at zero point, y0) carry out respectively linearization process, simultaneously according to this sampling intersection point (xn, yn ') with zero point (x0, y0) rat tail the lines attribute obtain the adjusted value that the measurement data of sensor is revised and store, to utilize this adjusted value the measurement data in the measuring process is revised.
For example, in the manufacturing process of digital display appliance, a calibration process is arranged, at this moment, operator (not shown) moves to zero point with the mechanical measurement structure first, and the measurement data x0 of the sensor by load module notification processor record zero point, simultaneously the actual value y0=0 at corresponding record zero point; Then, mechanically moving is measured structure to sampled point y1, the measurement data x1 of sensor when being recorded in simultaneously sampled point y1, re-use the actual value y1 ' that standard gauge block detects described sampled point, and by load module with this actual value y1 ' input processor and with data recording for the sampling intersection point (x1, y1 '); At last, processor will be sampled according to the embedded software algorithm and be drawn a straight line at intersection point (x1, y1 ') and zero point (x0, y0), and the slope of straight line represents with k1, and hence one can see that: y1 '-y1=k1* (x1-x0); And the y1 ' in the formula, y0, x0, x1 are known number, can obtain k1=(y1 '-y1)/(x1-x0); Thereby for any point y1=y0+k1* on this straight line (x1-x0), namely processor can utilize the measurement data x1 at 1 pair of this y1 point place of this slope k to revise to obtain the true measurement numerical value of object under test.Namely in the present embodiment, this slope k 1 is the adjusted value of processor in order to the output measurement data of the sensor of the utility model digital display appliance is revised.In the above-described embodiment, connect with straight line between sampling intersection point (x1, y1 ') and zero point (x0, y0), and carry out the corrected Calculation of actual measurement data take the slope k 1 of this straight line as adjusted value; Really, in other are implemented, described processor also can be set to by adopting 2 curves or 3 curves to connect, thereby utilize 2 times or 3 curves calculate and obtain the adjusted value that can revise the measurement data of sensor output, and then so that the utility model digital display appliance can be exported accurate measurement data.
The measuring method of the utility model digital display appliance may further comprise the steps,
At first, utilize the mechanical measurement structure that one object under test (not shown) is measured;
Secondly, sensor receives measurement data and by the digital measurement circuit module measurement data is passed to processor;
Then, processor is revised the measurement data that sensor records according to pre-stored adjusted value, and sends revised measurement data to display;
At last, display receives the revised measurement data line output of going forward side by side and shows.
In sum, the utility model digital display appliance passes through internal processor, can utilize thus the embedded software algorithm of this processor to obtain the adjusted value that physical construction error or other rigging errors of this digital display appliance are carried out correction-compensation, so that the utility model digital display appliance can effectively be revised to the mechanical measurement structure measurement and by the measurement data of sensor output, and then enhance productivity, reduce production costs simultaneously, and can satisfy high-precision measurement demand.
