Tool is described in detail above, and there are three the representative instances of actuator, it will be appreciated by those of skill in the art that this hair
Bright embodiment can also include more actuators, and embodiment of the present invention is to this and is not limited.
In one embodiment, test device 201 is used for analog temperature sensor, and the first actuator 203 is electronic vapour
The water pump of vehicle heat management pipeline, the second actuator 204 are the solenoid valve 204 of electric car heat management pipeline, third actuator 205
For the radiator fan of electric car heat management pipeline；Analog sensed signal is the temperature simulation letter in electric car heat management pipeline
Number；First control instruction is water pump open command；Second control instruction is solenoid valve open instructions；Third control instruction is heat dissipation
Starting fan instruction.
For example, test device 201 receives the temperature input value (for example being 35 degrees Celsius) that user is manually entered.Test device
201 convert temperature input value to the voltage signal of analog format.Test device 201 turns the voltage signal number of analog format
It is changed to the voltage signal of the number format as temperature analog signal.Then, the transducing signal of test device 201 to controller is defeated
Incoming interface output temperature analog signal (i.e. the voltage signal of number format).
It is as follows that processing logic is pre-saved in controller 202: when temperature is greater than preset threshold value (such as 30
Degree Celsius) when, water pump open command, solenoid valve open instructions and radiator fan enabled instruction are generated respectively.When temperature is lower than pre-
When threshold value (such as 30 degrees Celsius) first set, instruction is not generated.In this example, since temperature analog signal is greater than 30 degree,

Input value is converted into the voltage signal of analog format.The voltage signal number of analog format is converted to conduct by test device 201
The voltage signal of the number format of temperature analog signal.Then, the transducing signal input interface of test device 201 to controller is defeated
Outflow analog signal (i.e. the voltage signal of the number format).
It is as follows that processing logic has been pre-saved in controller 202: when flow is zero, being generated water pump stopping respectively and is referred to
It enables, solenoid valve out code and radiator fan halt instruction.When flow is not zero, instruction is not generated.In this example, due to stream
Amount is 0, therefore controller 202 generates water pump halt instruction, solenoid valve out code and radiator fan halt instruction respectively.
Moreover, controller 202 to water pump send water pump halt instruction, to solenoid valve send solenoid valve out code, to dissipate
Hot-air fan sends radiator fan halt instruction.Then, the executive condition of Observation personnel observation water pump, solenoid valve and radiator fan.
Assert that parallel water pump passes through when water pump smoothly stops, Observation personnel can be assumed that water pump is normal；When water pump cannot smoothly stop
When assert that parallel water pump does not pass through, Observation personnel can be assumed that between water pump abnormal, controller exception or water pump and controller
Pipeline is abnormal.Assert that electromagnetism valve test passes through when solenoid valve is smoothly closed, Observation personnel can be assumed that solenoid valve is normal；Work as electricity
Assert that electromagnetism valve test does not pass through when magnet valve cannot be closed smoothly, Observation personnel can be assumed that solenoid valve is abnormal, controller is abnormal
Or the pipeline between solenoid valve and controller is abnormal；Assert that radiator fan test passes through when radiator fan smoothly stops, observing
Personnel can be assumed that radiator fan is normal；Assert that radiator fan test does not pass through when radiator fan cannot smoothly stop, observing
Personnel can be assumed that the pipeline between radiator fan abnormal, controller exception or radiator fan and controller is abnormal.
The type for the sensing amount input value that user manually enters is distinguished for the ease of test device 201, test device 201 can
To prompt user to further provide for the type of inputted sensing amount input value.It is used as sensing amount defeated for example, user inputs one
After the number for entering value, user further inputs the mark (such as T) for representing temperature Type, then test device 201 is based on temperature
The mark of type is spent, the sensing amount input value inputted before confirmation user is temperature sensing amount input value.For another example, user inputs
