Example two
The embodiment provides a detection method of a water pump controller, which is used for the detection system of the water pump controller in the first embodiment and is executed by an upper computer. As shown in fig. 2, the detection method of the water pump controller 100 includes the following steps:
and S1, controlling the first solenoid valve 4 and the third solenoid valve 7 to be continuously opened for a first preset time, and controlling the second solenoid valve 5 and the fourth solenoid valve 8 to be closed, so that the liquid in the high-temperature box 1 flows through the water pump controller 100.
In step S1, the upper computer controls the first solenoid valve 4 and the third solenoid valve 7 to open for a first preset time, at which time the liquid in the high temperature box 1 flows through the water pump controller 100. In some embodiments, the first predetermined period of time is illustratively 2-3 minutes.
And S2, controlling the first electromagnetic valve 4 and the third electromagnetic valve 7 to be closed, and controlling the second electromagnetic valve 5 and the fourth electromagnetic valve 8 to be continuously opened for a second preset time period, so that the liquid in the low-temperature box body 2 flows through the water pump controller 100.
After the first electromagnetic valve 4 and the third electromagnetic valve 7 are opened for a first preset time, the upper computer controls the first electromagnetic valve 4 and the third electromagnetic valve 7 to be closed and controls the second electromagnetic valve 5 and the fourth electromagnetic valve 8 to be opened, so that the low-temperature liquid in the low-temperature box body 2 flows through the water pump controller 100. The second solenoid valve 5 and the fourth solenoid valve 8 are opened for a second preset time period, and the second preset time period is 2-3 minutes as an example.
And S3, executing a circulating step, wherein the circulating step comprises the step of circularly executing the step S1 and the step S2 for a preset time or a preset number of times, and when the upper computer determines that the received working signal sent by the water pump controller 100 is a failure signal, the upper computer controls the first electromagnetic valve 4, the second electromagnetic valve 5, the third electromagnetic valve 7 and the fourth electromagnetic valve 8 to be closed, and the circulating step is ended.
And in the range of the preset time length or the preset times, when the upper computer determines that the received working signal sent by the water pump controller 100 is a failure signal, the high-temperature loop and the low-temperature loop are turned off, and the detection is finished. In some embodiments, the predetermined time period is 15 days or 300 hours, and the predetermined number of times is 3000.
It should be noted that, in order to ensure the safety of the detection system of the water pump controller, when the flow sensor (i.e., at least one of the first flow sensor 19, the second flow sensor 26, and the third flow sensor 27) in the system sends a failure signal to the upper computer, it indicates that no fluid exists in the pipeline, and at this time, the upper computer controls the whole system to stop, and the detection is finished.
Further, in step S1, the third solenoid valve 7 is opened, and the first solenoid valve 4 is opened after a first delay period. In step S2, the first solenoid valve 4 is closed, the third solenoid valve 7 is closed after a second delay period, and the fourth solenoid valve 8 is opened to pump out the high-temperature liquid in the high-temperature loop as much as possible, so as to prevent the high-temperature liquid and the low-temperature liquid from being mixed in a large amount, and facilitate the control of the liquid temperature in the high-temperature box 1 and the liquid temperature in the low-temperature box 2. After a third delay period for opening the fourth solenoid valve 8, the second solenoid valve 5 is opened, after the second solenoid valve 5 and the fourth solenoid valve 8 are continuously opened for a second preset period, the second solenoid valve 5 is closed, and after a fourth delay period, the fourth solenoid valve 8 is closed. For example, in the embodiment, the first delay time period may be 0.5 to 1.5 seconds, the second delay time period may be 4 to 6 seconds, the third delay time period may be 0.5 to 1.5 seconds, and the fourth delay time period may be 4 to 6 seconds.
