Automobile air-conditioning throttle durability test device of the present invention is used to carry out the test of automobile air-conditioning throttle endurance quality.As shown in Figure 1, the concrete steps of automobile air-conditioning throttle endurance performance testing method of the present invention are as follows:
Step 101, arranges initial parameter.
In this step, according to concrete test request, set the first feedback voltage, the second feedback voltage, the first off-position time, the second off-position time and target circulation times N with Programmable Logic Controller 5, and by cycle index i clearing, i.e. i=0.Such as, setting the first feedback voltage in the present embodiment is 0.5V, and the second feedback voltage is 4.5V, and target circulation number of times is 30000 times (N=30000); Wherein target circulation number of times is by the counter equal of Programmable Logic Controller 5 inside, and the first off-position time and the second off-position time are respectively by the first timer and second timer sets of Programmable Logic Controller 5 inside.In addition, in the present embodiment, user can utilize the function button on touch-screen 5 to carry out aforesaid operations.
Step 102, command motor is with the first mode operation.
In this step, each motor rotation of Programmable Logic Controller 5 instruction and to make in the feedback voltage convergence step 101 of each motor the first feedback voltage of setting, when the feedback voltage of motor arrives the first feedback voltage, command motor is out of service.
Particularly, analog quantity spread module 6 obtains the feedback voltage of motor 1,2,3 and 4 in real time, and the feedback voltage of each motor is transferred to Programmable Logic Controller 5.Programmable Logic Controller 5 is by comparing feedback voltage and first feedback voltage (0.5V) of each motor, and command motor forward or reverse is to make feedback voltage convergence first feedback voltage of this motor; When the feedback voltage of motor arrives the first feedback voltage, command motor is out of service.For motor 1, analog quantity spread module 6 obtains the feedback voltage of motor 1 in real time, and this feedback voltage is transferred to Programmable Logic Controller 5; Programmable Logic Controller 5 is by comparing this feedback voltage and the first feedback voltage determines motor 1 forward or reverse; When Programmable Logic Controller 5 determines that motor 1 rotates forward, it sends rotating forward instruction, adhesive first relay 11 and disconnect the second relay 12, motor 1 is rotated forward; When Programmable Logic Controller 5 determines that motor 1 reverses, it sends rotating forward instruction, adhesive second relay 12 and disconnect the first relay 11, motor 1 is reversed; When the feedback voltage of motor 1 arrives the first feedback voltage, Programmable Logic Controller 5 command motor is out of service, disconnects the first relay 11 and disconnects the second relay 12, making motor 1 out of service.Similarly, analog quantity spread module 6 obtains the feedback voltage of other motors, and Programmable Logic Controller 6 compares the feedback voltage of other motors and the first feedback voltage to control the rotary state of other motors.
Step 103, command motor keeps state out of service.
In this step, when the feedback voltage of each motor all arrives the first feedback voltage, start the timing of the first off-position time, and each motor of instruction keeps state out of service within the first off-position time.
Particularly, when motor 1,2,3 and 4 all arrives the first feedback voltage, all motors are all out of service, and at this moment the first timer of Programmable Logic Controller 5 inside starts timing; Each motor of Programmable Logic Controller 5 instruction keeps state out of service within the first off-position time.The first off-position time that such as, set in step 101 is 10s, then 10s during the timer of Programmable Logic Controller 5 inside, each motor of Programmable Logic Controller 5 instruction keeps state out of service in 10s.

Step 105, command motor keeps state out of service.
In this step, when the feedback voltage of each motor all arrives the second feedback voltage, start the timing of the second off-position time, and each motor of instruction keeps state out of service within the second off-position time.
Particularly, when motor 1,2,3 and 4 all arrives the second feedback voltage, all motors are all out of service, and at this moment the second timer of Programmable Logic Controller 5 inside starts timing; Each motor of Programmable Logic Controller 5 instruction keeps state out of service within the second off-position time.The second off-position time that such as, set in step 101 is 15s, then 15s during the second timer of Programmable Logic Controller 5 inside, each motor of Programmable Logic Controller 5 instruction keeps state out of service within 15s.
Step 106, makes cycle index increase once, more cycle index and target circulation number of times.
In this step, when the second off-position time timing in step 105 terminates, the counter of Programmable Logic Controller 5 inside makes cycle index i increase once, i.e. i++.The target circulation times N that counter has set in cycle index i and step 101 more, if cycle index i is less than target circulation times N, then enters step 102; If cycle index i is not less than target circulation times N, then test end.Wherein, the control loop end of all relays can be cut off by Programmable Logic Controller 5 instruction, motor 1,2,3,4 and fan blower 14 out of service.
