Abstract

The invention discloses a method for detecting the heating function of a sanding device. The method comprises the following steps of adjusting ambient temperature, and testing the heating function of sanding, and is characterized in that: a variable value of the ambient temperature is set to be lower than a standard value by connecting a notebook computer with a train main microprocessor unit (MPU), so that closing of a heating loop is ensured; and the surface temperature of a heating module is tested by a point thermometer, if the temperature rises continuously, the heating function of the sanding device is normal. Compared with the prior art, the method has the advantages that: 1, detection of the heating function of the sanding device is realized when the ambient temperature is high in summer; 2, in the process of detection, the variable value of the ambient temperature is reset without detaching any part does not need to be dismantled, any personal safety risk does not exist, and meanwhile, the method is simple to operate and improves practical working efficiency; and 3, the limit of the ambient temperature is got rid of, detection can be performed at any ambient temperature, so the method is universal and unified.

Description

A kind of sander heating function detection method

Technical field

The invention belongs to vehicle testing and measuring technology technical field, relate to a kind of EMU sander heating function characterization processes method.

Background technology

Because EMU sander heating function has added the signal that receives ambient temperature control, promptly has only after ambient temperature is lower than certain value, the stucco heating function can start automatically.Adopt conventional through the ambient temperature sensor is cooled to rapidly below the design temperature standard value; There is following problem in the heating module work detecting method on the sander thereby make: the one, it is inner that the ambient temperature sensor of vehicle all is installed in the vehicle top air conditioner unit, need pull down during test roof kuppe, air-conditioning unit outer cover etc. big, than heavy parts; The 2nd, contact net has all sent specified AC25000V voltage above the roof when vehicle is debugged, because the security reason commissioning staff can not step on the roof environment temperature sensor simulation that cools to external world.This caused when summer, ambient temperature was higher, and conventional detection method can't satisfy the stucco heating and detect requirement.

Summary of the invention

Technical matters to be solved by this invention provides a kind of detection method that can under various environment temperatures, detect the stucco heating function.

For solving the problems of the technologies described above; The present invention provides a kind of EMUs stucco heating function detection method; Comprise outer temperature adjustment, the test of stucco heating function; It is characterized in that: link to each other with train master MPU through notebook computer, the external temperature variate-value is set is lower than standard value, thereby guaranteed the closure of heating loop; With the warm instrumentation examination of some heating module surface temperature,, prove that promptly the sander heating function is normal when temperature continues to rise.

Advantage and good effect that the relative background technology of the present invention produces are following:

1, realized when summer, ambient temperature was higher, the detection of sander heating function.

2, in detection, only need external temperature variable to reset, need not tear any parts open, there is not any personal security risk, simple to operate simultaneously, improved real work efficient.

3, break away from the restriction that receives ambient temperature, can outside any, detect under the temperature, realized versatility, the unitarity of detection method.

Description of drawings

Accompanying drawing be notebook computer link to each other with MPU the test synoptic diagram.

Embodiment

With reference to accompanying drawing, when carrying out the detection of sander heating function, debugging software notebook computer 2 will be installed link to each other with main MPU 1 (activating cab one end MPU) through data line 3; Start SERLINK98 debugging software (first use will be provided with transfer rate), find outer warm variable cltempaemedia_gul, and warm variate-value is lower than standard value outside giving; Stucco adds the electrothermal relay adhesive; Thereby the heating loop is constituted, utilize the warm instrumentation examination of point to be installed in the heating module surface temperature on sander and the pipeline thereof, function just often; As time goes on and gradually the module temperature will raise, and promptly realize the detection to the sander heating function.

Claims

1. sander heating function detection method; Comprise outer temperature adjustment, the test of stucco heating function, it is characterized in that: link to each other with train master MPU through notebook computer, the external temperature variate-value is set is lower than standard value; Stucco adds the electrothermal relay adhesive, thereby has guaranteed the closure of heating loop; With the warm instrumentation examination of some heating module surface temperature,, prove that promptly the sander heating function is normal when temperature continues to rise.
