Comprehensive detector for automobile electronic fan

Abstract

The invention discloses a comprehensive detector for an automobile electronic fan. The comprehensive detector is characterized by comprising a microprocessor 1, as well as a power supply module, a current detection module 4, a PWM signal simulation module 9, an electronic fan motor driving module 10, an LED display driving module 13 and an LED display 14 which are respectively connected with the microprocessor, wherein the output end of the electronic fan motor driving module is connected with the output end of the PWM signal simulation module and then connected with an automobile electronic fan assembly. The current value of a motor and the resistance value of a speed regulating resistor in each actual running mode of the automobile electronic fan product are collected and displayed in real time so as to judge whether the current value and the resistance value are coincided with set parameter values or not. Therefore, the work condition of the automobile electronic fan can be dynamically analyzed, and problems related to the system are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of finished product detection of an automobile electronic fan, and in particular relates to a device for controlling the running state of an automobile electronic fan and automatic and manual detection during the detection of a finished product of an automobile electronic fan. Background technique [0002] In the existing finished product testing of automotive electronic fans, relay equipment is generally used to control the finished product testing of automotive electronic fans. Although the relay equipment can meet the requirements of finished product testing of automotive electronic fans to a certain extent, there are still the following deficiencies: , which mainly has the following deficiencies: 1. A single type of automotive electronic fan corresponds to one device, and its versatility cannot meet the requirements; 2. It can only be controlled and detected manually, without automatic detection function,...

[0002] In the existing finished product testing of automotive electronic fans, relay equipment is generally used to control the finished product testing of automotive electronic fans. Although the relay equipment can meet the requirements of finished product testing of automotive electronic fans to a certain extent, there are still the following deficiencies: , which mainly has the following deficiencies: 1. A single type of automotive electronic fan corresponds to one device, and its versatility cannot meet the requirements; 2. It can only be controlled and detected manually, without automatic detection function, it is difficult to control manually, and there is no alarm function, resulting in inefficiency 3. The contact of the relay is easy to be ablated under long-term high current, and the reliability cannot meet the requirements of use; 4. The interactive interface of the drone cannot be intuitively set and displayed. The change of duty cycle in the process of finished product inspection affects the analysis of unqualified products
