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, the first test device 201 is used for analog temperature sensor, and the first actuator 203 is electricity
The water pump of electrical automobile heat management pipeline, the second actuator 204 are the solenoid valve 204 of electric car heat management pipeline, and third executes
Device 205 is the radiator fan of electric car heat management pipeline；First analog sensed signal is in electric car heat management pipeline
Temperature analog signal；First control instruction is water pump open command；Second control instruction is solenoid valve open instructions；Third control
Instruction is radiator fan enabled instruction.
For example, the first test device 201 receives the first temperature input value (for example being 35 degrees Celsius) that user is manually entered.
The first temperature input value is converted analog voltage signal by first test device 201.First test device 201 believes analog voltage
Number word is converted to the digital voltage signal as temperature analog signal.Then, sensing of first test device 201 to controller
Signal input interface output temperature analog signal.
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,
Therefore controller 202 generates water pump open command, solenoid valve open instructions and radiator fan enabled instruction respectively.
Moreover, controller 202 to water pump send water pump open command, to solenoid valve send solenoid valve open instructions, to dissipate
Hot-air fan sends radiator fan enabled 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 is smoothly opened, Observation personnel can be assumed that water pump is normal；When water pump cannot be opened smoothly
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 smooth opening, 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 is unable to smooth opening, 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 starts, observes
Personnel can be assumed that radiator fan is normal；Assert that radiator fan test does not pass through when radiator fan cannot smoothly start, observes
Personnel can be assumed that the pipeline between radiator fan abnormal, controller exception or radiator fan and controller is abnormal.
Similarly, when needing to adjust the temperature value of temperature analog signal, it is only necessary to which user is manually in the first test device
The first sensing amount input value is adjusted on 201, and the test to pipeline can be realized there is no need to expensive devices such as environment storehouses.
In one embodiment, the first test device 201 is used for analogue flow rate sensor, and the first actuator 203 is electricity
The water pump of electrical automobile heat management pipeline, the second actuator 204 are the solenoid valve of electric car heat management pipeline, third actuator
205 be the radiator fan of electric car heat management pipeline；First analog sensed signal is the stream in electric car heat management pipeline
Measure analog signal；First control instruction is water pump halt instruction；Second control instruction is solenoid valve out code；Third control refers to
Enabling is radiator fan halt instruction.
For example, the first test device 201 receives the first flow input value (for example being 0) that user is manually entered, by first
Flow input value is converted into analog voltage signal.First test device 201 is converted to analog voltage signal number as temperature
The digital voltage signal of analog signal.Then, transducing signal input interface output flow of first test device 201 to controller
Analog signal.
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.
