Amount analogue signal；First simulation control instruction is water pump halt instruction；Second simulation control instruction is closed electromagnetic valve instruction；The
Three simulation control instructions are 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, and analog voltage signal numeral is converted to the numeral electricity as temperature analog signal
Pressure signal.Then, the first test device 201 transducing signal input interface output flow analogue signal to controller.
In the second test device 202, pre-save process logic as follows: when flow is zero, generated water pump respectively and stop
Only instruction, closed electromagnetic valve instruction and radiator fan halt instruction.When flow is not zero, do not generate instruction.In this example, by
Being 0 in flow, therefore controller 202 generates water pump halt instruction, closed electromagnetic valve instruction and radiator fan halt instruction respectively.
Preferably, arrange interface at the second test device 202, process logic can be write with a brush dipped in Chinese ink by interface.
And, the second test device 202 sends water pump halt instruction to water pump, sends closed electromagnetic valve to electromagnetic valve and refers to
Order, sends radiator fan halt instruction to radiator fan.Then, observation personnel observe holding of water pump, electromagnetic valve and radiator fan
Market condition.Assert that when water pump stops smoothly parallel water pump passes through, observation personnel are it can be assumed that water pump is normal and arrival water pump
Pipeline normal；Assert that when water pump can not stop smoothly parallel water pump does not passes through, observation personnel it can be assumed that water pump is abnormal or
The pipeline arriving water pump is abnormal.Assert that when electromagnetic valve cuts out smoothly electromagnetic valve test is passed through, personnel are it can be assumed that electromagnetism in observation
Valve is normal；Assert that when electromagnetic valve can not cut out smoothly electromagnetic valve test is not passed through, observation personnel are it can be assumed that electromagnetic valve is abnormal
Or arrive the pipeline of electromagnetic valve extremely；Assert that when radiator fan stops smoothly radiator fan test is passed through, personnel are permissible in observation
Assert that radiator fan is normal；Assert that when radiator fan can not stop smoothly radiator fan test is not passed through, personnel are permissible in observation
