[New patent introduction] How to realize the performance test of the IC card smart water meter electric control valve

It is reported that on November 28, 2017, Xi'an Aerospace Metrology and Testing Institute applied for a national invention authorized patent-IC card smart water meter electronic control valve performance test system and implementation method. The invention relates to an IC card intelligent water meter electric control valve performance test system and an implementation method, and belongs to the field of instrumentation.

Background of the invention

As the core component of the IC card smart water meter, the electronic control valve is closely related to the quality of the base meter. Reliable switching of electronic control valves is the most important thing to ensure product quality. Whether the performance of the electronic control valve is reliable needs to be determined by the durability test of the electronic control valve. In the test, the water meter is required to open and close the electric valve 1000 times at the usual flow rate (Q3). After that, the valve is required to be closed to test the leakage. At present, the durability test of electronic control valves of water meters is generally realized by manual card-controlled valve switching. Manual operation takes at least 6 days to complete, which is time-consuming and inefficient. Moreover, the card-controlled switching valve is troublesome to operate, and manual data recording is prone to deviation.

In view of this situation, the present invention provides a test system and implementation method. The method mainly adopts single-chip microcomputer programming to automatically control the switch of the electronic control valve, and displays the switch state of the electronic control valve through the indicator light. The number of valve switching times is accumulated by the variables in the program and displayed on the LCD.

Summary of the invention

In order to solve the technical problems of complicated manual operation process and inaccurate results in the performance test process of the existing IC card smart water meter electric control valve, the present invention provides an IC card smart water meter electric control valve performance test system and implementation method.

The figure shows the principle block diagram of the present invention

The IC card intelligent water meter electric control valve performance test system includes a valve switch state detection module, a switch state prompt module, a valve control module, a delay control module, a counting module and a single-chip microcomputer. The valve control module is used to switch the switching state of the electronically controlled valve, and sends instructions to the delay control module after each switching is completed; the delay control module is used to stop the set time after receiving the switching command from the valve control module Send a detection instruction to the valve switch state detection module; the valve switch state detection module is used to detect the switching state of the electronically controlled valve after receiving the detection instruction, and send it to the switch state prompt module; the switch state prompt module is used to issue different changes according to the switch state Reminder; every time the valve control module drives the electronically controlled valve to open and close each time, the counting module will accumulate the number of switching times by one; the single-chip microcomputer controls the valve switch state detection module, switch state prompt module, valve control module, delay control module, and counting module to work .

The system also includes a display module, which includes a display drive module and a display device. The display drive module is used to send the switching times sent by the counting module to the display device for display. The switch state prompt module includes an LED light display module, an LED red light circuit and an LED green light circuit. The LED light display module receives the switch state and drives the LED red light circuit or the LED green light circuit according to the difference of the switch state. The set time is 12s, and the one-chip computer is MSP430F4152.
