Description
Technical field
The invention belongs to Automobile Measuring Techniques field, more particularly to a kind of PWM cooling fan controllers test platform.
Background technology
Publication No. CN102444571A files, disclose " a kind of fan test system, including one be used for test a fan
Control device and a test control device for being electrically connected with the control device and fan, the test control device includes one
Microcontroller, a switch module and a modular converter, the switch module control microcontroller send pulse control signal to institute
Fan is stated, the fan adjusts its rotating speed according to the pulse control signal received, and its tach signal is sent to described micro-
Controller, the microcontroller reads rotation voltage of the fan under different rotating speeds and rotates electric current, and by rotation speed of the fan, rotate
Voltage and rotation electric current are sent to control device via the modular converter.Fan test system of the present invention is controlled by the test
Device processed is tested fan automatically, and test result is sent into the control device at the end of test, automates journey
Degree is improved ".However, the technical scheme is not particularly suited for the test of automobile cooling fan.
It can be tested during existing cooling fan test using actual loading, but fan is loaded as testboard bay
When, usually because peripheral operating mode (temperature, air circulation situation) is different and is unable to reach rated power, and because fan aging is led
The load condition of cause changes, and fan is easily bad, and system cost is high, and environmental noise is big.Moreover, short-term actual loading aging
In early detection and (metal-oxide-semiconductor) failure welding product can not be filtered out.
