Detection method of automobile starting switch

Abstract

The invention discloses a detection method of an automobile starting switch. In an actual application process, establishing a two-dimensional coordinate system by using the current brightness photoelectric induction value Gi and the brightness standard value Si, meanwhile, a brightness linear function relation y=k1x+b1 is obtained through linear fitting, after the brightness linear function relationship y=k1x+b1 is successfully verified, the brightness linear function relationship y=k1x+b1 is obtained, the optical parameter of the automobile starting switch is connected with the electrical parameter of an optical sensor, subsequently, the batch brightness detection of the automobile starting switch can be completed only by using the brightness linear function relationship y=k1x+b1, the detection operation steps of the automobile starting switch can be greatly simplified, the detection precision can be greatly improved, and compared with existing detection through professional equipment, the detection cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of detection of an automobile start switch, in particular to a detection method of an automobile start switch. Background technique [0002] For LED light-emitting indicator switches such as car start switches, if the LED is assembled in the switch, when the light emitted by the LED passes through the light-transmitting or light-conducting material of the switch, its brightness and wavelength will be affected, even if the same parameter LED is used for different switches. When using a transparent or light-guiding material, the brightness and wavelength it exhibits are also different. [0003] For example, in the manufacturing process of LED light-emitting indicator switches such as car start switches, the brightness and wavelength of the detector must be determined. Usually, due to the difficulty of detecting brightness and wavelength and the high accuracy in specific implementation, no matter its profession...

AI Technical Summary

Problems solved by technology

[0004] Since the LED light-emitting indicator switch such as the car start switch is a small mass-produced product, its product parameters include brightness and wavelength, which are necessary parameters for delivery and inspection. If each switch is tested by an authoritative testing organization such as a photoelectric metrology institute , the cost is very high, and it takes a long time. Considering the cost problem, it is impossible to conduct authoritative detection for each switch in the actual detection.

[0005] Furthermore, the cost of existing professional brightness and wavelength detection equipment for detection is relatively high. Even so, its accuracy is far inferior to the results obtained by authoritative detection institutions such as photoelectric metrology institutes.
