The representative instance with three executors described in detail above, it will be appreciated by those of skill in the art that this
Bright embodiment can also include more executor, and embodiment of the present invention is to this and indefinite.
In one embodiment, the first test device 201 is for analog temperature sensor, and the first executor 203 is electricity
The water pump of electrical automobile heat management pipeline, the second executor 204 is the electromagnetic valve 204 of electric automobile heat management pipeline, and the 3rd performs
Device 205 is the radiator fan of electric automobile heat management pipeline；First analog sensed signal is in electric automobile heat management pipeline
Temperature analog signal；First control instruction is water pump open command；Second control instruction is electromagnetic valve OPEN；3rd controls
Instruction is radiator fan enabled instruction.
Such as, the first test device 201 receives the first temperature input value (being such as 35 degrees Celsius) that user is manually entered.
First temperature input value is converted into analog voltage signal by the first test device 201.Analog voltage is believed by the first test device 201
Count word is converted to the digital voltage signal as temperature analog signal.Then, the first test device 201 sensing to controller
Signal input interface output temperature analogue signal.
Process logic has been pre-saved as follows: when temperature is more than threshold value set in advance (such as 30 in controller 202
Degree Celsius) time, generate water pump open command, electromagnetic valve OPEN and radiator fan enabled instruction respectively.When temperature is less than pre-
During threshold value (such as 30 degrees Celsius) first set, do not generate instruction.In this example, owing to temperature analog signal is more than 30 degree,
Therefore controller 202 generates water pump open command, electromagnetic valve OPEN and radiator fan enabled instruction respectively.

Amount analogue signal；First control instruction is water pump halt instruction；Second control instruction is closed electromagnetic valve instruction；3rd controls to refer to
Order is radiator fan halt instruction.
Such as, the first test device 201 receives the first flow input value (being such as 0) that user is manually entered, by first
Flow input value is converted into analog voltage signal.Analog voltage signal numeral is converted to as temperature by the first test device 201
The digital voltage signal of analogue signal.Then, the first test device 201 transducing signal input interface output flow to controller
Analogue signal.
In controller 202, pre-save process logic as follows: when flow is zero, generated water pump respectively and stop referring to
Make, closed electromagnetic valve instructs and radiator fan halt instruction.When flow is not zero, do not generate instruction.In this example, due to stream
Amount is 0, and therefore controller 202 generates water pump halt instruction, closed electromagnetic valve instruction and radiator fan halt instruction respectively.
And, controller 202 sends water pump halt instruction to water pump, sends closed electromagnetic valve instruction to electromagnetic valve, to dissipating
Hot-air fan sends radiator fan halt instruction.Then, observation personnel observe the implementation status of water pump, electromagnetic valve and radiator fan.
Assert that when water pump stops smoothly parallel water pump passes through, personnel are it can be assumed that water pump is normal in observation；When water pump can not stop smoothly
Time assert that parallel water pump does not passes through, observation personnel are it can be assumed that water pump is abnormal, between controller exception or water pump and controller
Pipeline is abnormal.Assert that when electromagnetic valve cuts out smoothly electromagnetic valve test is passed through, personnel are it can be assumed that electromagnetic valve is normal in observation；Work as electricity
Assert when magnet valve can not be closed smoothly that electromagnetic valve test is not passed through, observation personnel are it can be assumed that electromagnetic valve is abnormal, controller is abnormal
Or the pipeline between electromagnetic valve and controller is extremely；Assert that when radiator fan stops smoothly radiator fan test is passed through, observation
Personnel are it can be assumed that radiator fan is normal；Assert that when radiator fan can not stop smoothly radiator fan test is not passed through, observation
Personnel are it can be assumed that radiator fan pipeline extremely, between controller exception or radiator fan and controller is abnormal.
