[Instrument patent] IC card intelligent water meter electronic control valve performance test system and implementation method

[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduced a national invention-authorized patent - IC card intelligent water meter electronically controlled valve performance test system and implementation method. The patent was applied for by the Xi’an Aerospace Measurement and Testing Institute and was authorized to be published on November 28, 2017.

Content Description

The invention relates to an IC card intelligent water meter electronic control valve performance test system and a realization method, belonging to the instrumentation field.

Background of the invention

Electronic control valve as the core component of the smart meter of IC card, closely related to the quality of the base meter. Reliable switching of electronically controlled valves is a top priority in ensuring product quality. The reliability of the electronically controlled valve needs to be determined by the durability test of the electronically controlled valve. The test requires the water meter to open and close the valve 1000 times under the flow condition of the common flow (Q3). After that, the valve is required to be closed to measure the leakage. At present, the durability test of water meter electronically controlled valves generally adopts the manual card control valve switching mode. The manual operation needs to be completed in at least 6 days, which takes a long time and is inefficient, and the card control switch valve is inconvenient to operate, and it is easy to manually record the data.

In view of this situation, the present invention provides a test system and an implementation method thereof. The method mainly adopts a single-chip microcomputer programming to automatically control the electronically controlled valve switch and displays the switch state of the electronically controlled valve through an indicator lamp. The number of valve switches is accumulated by variables in the program and displayed by the LCD.

Summary of the Invention

In order to solve the technical problem that the existing IC card intelligent water meter electronic control valve performance test process adopts a complex manual operation process and inaccurate results, the present invention provides an IC card intelligent water meter electronic control valve performance test system and an implementation method.

The Figure is a functional block diagram of the present invention

IC card intelligent water meter electronic control valve performance test system includes valve switch status detection module, switch status prompt module, valve control module, delay control module, counting module and single chip microcomputer. The valve control module is used to switch the switch status of the electronic control valve, and sends an instruction to the delay control module after each switch is completed; the delay control module is used to stop the set time after receiving the switch instruction of the valve control module. Send a detection command to the valve switch status detection module; the valve switch status detection module is used to detect the switch status of the electronic control valve after receiving the detection command and send it to the switch status prompt module; the switch status prompt module is used to send different signals according to the switch status. Prompt; valve control module each drive electronic control valve on and off each time, count module will add the number of switches 1; microcontroller control valve switch status detection module, switch status prompt module, valve control module, delay control module, counting module work .

The system also includes a display module. The display module includes a display driver module and a display device. The display driver module is used to send the number of switches sent by the counting module to the display device for display. The switch status 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 status and drives the LED red light circuit or the LED green light circuit according to the different switch status. The set time is 12s and the microcontroller is MSP430F4152.
