Background
At present, most of equipment measurement principles are static measurement, the measured value is single, simple operation and judgment are carried out on the measured result, and the accuracy of the result only depends on basic means such as equipment periodic calibration, statistical analysis on the repeatedly measured result and the like. The measurement mode is that the sensor directly communicates with the PLC, and the principle of the measurement system is that acquired electric signals are sent to an industrial personal computer through a filter, data processing is carried out by an upper acquisition program to obtain measurement data information, and the measurement data information is transmitted to a PLC execution control system after the result is judged.
Therefore, the influence of external factors such as environmental changes, sensor failure, overdue uncalibrated and the like cannot be eliminated. In this way, the measurement value often generates measurement errors due to external interference (environment, equipment and personnel), and inestimable results are generated in the subsequent assembly process, so that defective products flow out, and the product quality cannot be guaranteed.

the measurement system judges that the equipment needs to be re-zeroed and provides an interrupt signal for triggering an automatic calibration program to the PLC;
and after receiving the interrupt request signal, the PLC controls the actuating mechanism to act to perform equipment zero calibration.
Further, pushing out the calibration sample piece, lifting the calibration sample piece by a lifting member, dropping a three-axis measuring head, starting to measure the calibration sample piece, repeatedly measuring for many times, subtracting a certificate value of a standard piece from a measured value to obtain a corrected value, correcting the zero position of the measuring machine, and finishing zero calibration of the equipment;
and after the return of the three-axis measuring head is finished, the lifting member falls down, the calibration sample is withdrawn, and the measurement of subsequent workpieces is started.
Based on the automatic calibration control method, the device for implementing the method comprises the following steps: calibrating a sample piece and a three-axis measuring head, wherein the three-axis measuring head is provided with a temperature sensor and a displacement sensor, real-time temperature signals and displacement measurement values acquired by the sensors are transmitted into a measuring system, and various conditions generated by external interference are defined by an internal program of the measuring system;
the temperature sensor collects real-time temperature signals, and the displacement sensor in the three-axis measuring head collects three-axis measured values of each workpiece.
By adopting the technical scheme, compared with the prior art, the invention has the following advantages: and a multi-condition parallel strategy is adopted for result judgment, so that the accuracy of the system measurement result is effectively ensured. The measuring system adopted by the invention is independent of the PLC, has unique processing right for the acquired signal, and can perform more interaction with the PLC.
