Detection method of automobile start switch

Abstract

The detection method of the automobile starting switch of the present invention, in the actual application process, utilizes the current brightness photoelectric induction value G i and brightness standard value S i Establish a two-dimensional coordinate system, and at the same time linearly fit to obtain the brightness linear function relationship y=k 1 x+b 1 , in the linear function relation to brightness y=k 1 x+b 1 After successful verification, establish a connection between the optical parameters of the car start switch and the electrical parameters of the optical sensor, and then only need to use the brightness linear function relationship y=k 1 x+b 1 It can complete the batch brightness detection of the car start switch, which can greatly simplify the detection operation steps of the car start switch, and can also greatly improve the detection accuracy. Compared with the existing professional equipment detection, the detection cost is also much higher. reduce.

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.
