Description

technical field [0001] The invention relates to the field of testing equipment and intelligent monitoring, in particular to a real-time testing system and control method for a rotational speed based on data collection. Background technique [0002] In a specific test, it is required to monitor the output frequency of the servo mechanism oil pump speed sensor and the output signal of the oil pump outlet pressure sensor in real time, and make a real-time judgment based on the real-time test data 2 seconds before the test. Only when the judgment conditions indicate that the servo mechanism is working normally can a feedback signal be sent to the control center, and the control center can continue to test only after receiving the feedback signal. Therefore, the test and judgment of the output frequency of the pump speed sensor and the output signal of the oil pump outlet pressure sensor are very important and the key to the success of the test. At present, real-time testing and...

AI Technical Summary

Problems solved by technology

At present, real-time testing and judgment cannot be realized for the frequency test of the speed sensor. Only the original pulse data output by the sensor can be tested, and the output frequency of the speed sensor can be determined by post-test processing. In addition, the condition interpretation of the data acquisition system is limited to judging one signal and Only a single corresponding feedback signal is output, and the simultaneous judgment of two signals in the task has not been realized, so the existing frequency test method cannot meet the test requirements of the test in the background technology
