Problems solved by technology
[0004] Compared with temperature-controlled fans, electronically-controlled fans have precise control, fast response, low fuel consumption, and low emissions. Joint analysis by the factory, fan factory, and ECU factory takes a long time and involves a lot of personnel; because the OEM often modifies the ECU control parameters, the test standards also need to be updated accordingly, which leads to the need to update the inspection software, and the update of the inspection software requires Complete a lot of program design work that matches the computer; because different OEMs have different testing standards, a large number of different troubleshooting software are required, causing after-sales personnel to master a lot of troubleshooting software skills, and the software purchase cost is also high. Higher; the existing test software does not have the function of data upload, and the data is stored on the test equipment, often because it is too late to export, resulting in data overflow and loss; the existing troubleshooting software does not have a self-test function. Stop the test and send it back to the original factory for overhaul, the time cost is high

The invention relates to a method for testing a silicon oil fan with a data interaction function. The method includes: standard import, fan identification and data upload. The test equipment used in the present invention is small and easy to carry, without the cooperation of external test equipment such as ECU, can independently transmit PWM signals, control the working status of the fan, and read the fan speed in real time, which is convenient for the investigation personnel to test the function of the fan, intuitive and fast, and can be greatly simplified The troubleshooting process; at the same time, it can interact with the remote server, download the latest test parameters and send back the test results to avoid loss of test results.
Description
technical field [0001] The invention relates to a silicon oil fan in a commercial vehicle engine cooling system, in particular to a testing method for a silicon oil fan with data interaction function. Background technique [0002] At present, on the commercial vehicle platform, the heat dissipation of the engine is mainly completed by the silicone oil fan. Its working principle is: the engine torque is transmitted through the viscous force of the silicone oil, and the fan blades are driven to rotate to dissipate heat for the engine radiator and air conditioner condenser. According to the working mode, it is divided into electric / Temperature-controlled silicone oil fan. [0003] The solenoid in the electronically controlled silicone oil fan is an electronic control component: the ECU of the whole vehicle inputs a PWM signal to the solenoid, and the solenoid generates a changing magnetic field, which attracts or opens the control valve stem in the fan, thereby adjusting the s...
