The invention relates to the technical field of speed sensor testing, and provides a speed sensor tester test assembly and a speed sensor tester. The test assembly of the speed sensor tester includes a mounting base, a speed measuring gear and a drive unit for driving the speed measuring gear, the mounting base includes a housing chamber, the speed measuring gear is located in the housing chamber, and the driving unit is fixed on the enclosure of the housing chamber, An observation window for the speed measuring gear is provided on the surrounding plate; the installation base also includes a sensor mounting plate, which is parallel to the axis of the speed measuring gear. The detection of the test components of this speed sensor tester is simple and convenient, and there is no need to return to the speed sensor manufacturer, and the speed measuring gear can be separated from the outside world to prevent impurities from contacting the speed measuring gear or hurting people by the speed measuring gear. And the observation window set up on the hoarding can meet the observation needs, so as to grasp the state of the speed measuring gear at any time. In addition, the arrangement of the sensor mounting plate can save the space occupied by the test components of the speed sensor tester.
Description
technical field [0001] The invention relates to the technical field of speed sensor testing, in particular to a speed sensor tester test assembly and a speed sensor tester. Background technique [0002] With the continuous expansion of the railway speed range and the increase of train speed, the working environment of the speed sensor is getting worse and worse. When the speed sensor is affected by factors such as shock vibration, alternating temperature and humidity, and working power fluctuations, it may cause the speed sensor to malfunction or falsely report, resulting in speed limit and parking, which seriously affects the operation order of my country's high-speed railway. Therefore, it is very necessary to test the train speed sensor. [0003] At present, the rail transit industry is widely using photoelectric speed sensors, Hall speed sensors and magnetoelectric speed sensors, and corresponding test devices are required. There are many ways to test the speed sensor....
