Abstract

The invention provides a method and device for testing the performance of a speed and vibration combined sensor, and the method comprises the steps: carrying out the collection and calculation of a vibration signal and a speed signal through a CPLD main control chip, and storing the vibration signal and the speed signal into a storage unit; after sampling is finished, controlling the motor to stop rotating through a control signal generated by the upper computer; and comparing the test data of the storage unit with a theoretical value for testing. The device comprises: an acquisition module, wherein a CPLD (Complex Programmable Logic Device) main control chip acquires and calculates a speed signal and a vibration signal and then stores the speed signal and the vibration signal into a storage unit; a test module which is used for comparing the test data with a theoretical value for testing; and a motor module which is used for receiving a signal of the CPLD main control chip and driving the equipment to be tested to generate a speed signal and a vibration signal. The testing method and device can solve the problem that no similar products exist in the current market, and are high in practicability.

Description

technical field [0001] The invention belongs to the field of sensor testing, specifically, the invention is a testing method and device for testing the performance of a speed vibration combined sensor Background technique [0002] The speed vibration combined sensor is a multi-functional sensor specially used in the field of rail transit. It can output the speed of the train wheel to the control system through the pulse or bus interface, and can also monitor the vibration state of the axle. Currently, there is no test method and device for performing function and performance tests on the above-mentioned speed-vibration combined sensor in the market. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The object of the present invention is to provide a test method and device for performance testing of a speed-vibration combined sensor. The test device and method can test the speed-vibration combined sensor. The present invention ...
