Embodiment Construction

[0026] The present invention will be further detailed below in conjunction with the accompanying drawings:

[0027] See figure 1 As shown, the eddy current retarder coil resistance test system includes a host computer, a resistance tester, an infrared temperature probe, an infrared data processing module, and a coil to be tested. The resistance tester measures the resistance value of the coil to be tested, and sends the measured resistance value through the serial port RS 232 Transmitted to the host computer; the infrared temperature probe senses the surface temperature of the coil to be measured through infrared rays, and the induced temperature signal is converted into temperature data by the infrared data processing module, and then passes through the serial port RS 232 Transfer to the host computer. The upper computer performs temperature calibration on the measured resistance value, and then compares and analyzes the resistance standard range value set, judges and displays th...

Abstract

The invention relates to an eddy current retarder coil resistance test system and a test method thereof. A resistance tester of the test system measures a resistance value of a coil to be tested, and resistance value data is transmitted to a host computer via a serial port. An infrared temperature measurement probe senses a surface temperature of the coil to be tested, an infrared data processing module converts the temperature into temperature data, and the temperature data is transmitted to the host computer through the serial port. A resistance value temperature is calibrated, a set resistance standard range value is compared and analyzed, a detection result is determined and displayed, and a test result and the data are stored. The test method comprises the following steps of (1) inputting a product number of the coil to be tested so that the host computer automatically pops up the resistance standard range value of the coil to be tested; (2) clicking a ''detect'' button; (3) obtaining the resistance value collected by a resistance tester and a temperature value collected by the infrared temperature measurement probe; (4) carrying out temperature calibration, and acquiring a corresponding resistance value R20 at 20 DEG C; and (5) determining whether the R20 is within the set resistance standard range, if so, displaying ''qualified test''; and if not, displaying ''failed test''.

Description

Technical field [0001] The invention relates to a test system and a test method for components of automobile auxiliary braking products, in particular to an eddy current retarder coil resistance test system and a test method. Background technique [0002] CN201710969920.8 discloses a multi-station resistance automatic test device and its test method, its purpose is to provide a convenient and easy to use, test data touch screen HMI display and can automatically determine whether the resistance of load resistance products The multi-station resistance automatic test device and test method that are qualified and can measure multiple resistances to be tested at the same time are especially suitable for batch application production lines and resistance production sites to determine the consistency of the resistance products to be tested, which greatly reduces the on-site The labor intensity of the tester, and the test accuracy is high. The technical solution: the said resistance test...
