It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Example 1

[0020] A flow meter valve control controller detection device comprises a power module 1, an indicator light module 2, a main control circuit board 3 and an assembly junction box 4; the power module 1, the indicator light module 2 and the main control circuit board 3 are sequentially connected and arranged in the assembly junction box 4; the main control circuit board 3 is used to receive the setting instructions of the application system, and is used to test the type of the flow meter valve control controller and the relevant protocols according to the setting instructions of the remote center, and can transmit the relevant setting parameters back to the application system, and is used to store according to the setting instructions of the application system, and when the test product sends an RS485 data read request, it replies according to the relevant flow meter protocol data; the application system sends a read setting parameter instruction, and the main control circuit board 3 replies with the device storage data.

[0021] Example 2

[0022] On the basis of Example 1, the power module 1 is composed of four dry batteries for supplying power to the indicator light module 2 and the main control circuit board 3.

[0023] Example 3

[0024] On the basis of Example 1, the indicator light module 2 mainly includes a valve opening indicator light 21, a valve closing indicator light 22, a 24V DC indicator light 23 and a valve interface 24; the 24V DC indicator light 23 mainly detects whether the valve control controller of the flow meter under test has a 24V DC output, and when it has a 24V DC output, the 24V DC indicator light 23 lights up; the valve interface 24 is mainly used to connect the valve control controller of the flow meter under test with this practical flow meter valve control controller detection device.

[0025] Example 4

[0026] On the basis of Example 1, the main control circuit board 3 includes a valve detection module 31, an antenna 32, a wireless communication module 33, a communication success reminder module 34, a DC power conversion module 35, a single-chip computer 37, an RS485 communication module 37, a power interface 38, and a controller connection interface 39. The power interface 38 is electrically connected to the power supply 1, and the DC power conversion module 35 is electrically connected to the valve detection module 31, the wireless communication module 33, the communication success reminder module 34, the single-chip computer 36, and the RS485 communication module 37.

[0027] The single chip microcomputer 36 is electrically connected to the valve detection module 31 , the wireless communication module 33 , the communication success reminder module 34 and the RS485 communication module 37 .

[0028] The wireless communication module 33 is electrically connected to the antenna 32 .

[0029] The controller connection interface 39 is connected to the flow meter valve control controller.

[0030] Specifically, the DC power conversion module 35 converts 6V into 3.3V DC power and outputs it to the microcontroller 36 and the communication success reminder module 34; the DC power conversion module 35 converts 6V into 3.6V DC and outputs it to the wireless communication module 33; the DC power conversion module 35 converts 6V into 5V DC and outputs it to the RS485 communication module 37.

[0031] Specifically, the valve detection module 31 mainly detects the valve opening and closing states of the valve controller of the flow meter under test. When the test product is in the valve opening state, the valve opening indicator light 21 is on; when the test product is in the valve closing state, the valve closing indicator light 22 is on;

[0032] The antenna 32 is connected to the wireless communication module 33 and is mainly used for receiving and sending wireless signals.

[0033] Exemplarily, the wireless communication module 33 is a NB module, which is used to receive setting instructions of the application system and to transmit relevant setting parameters back to the application system.

[0034] The communication success reminder module 34 is mainly used for RS485 communication reminder. When it is detected that the data sent by the valve control controller of the flow meter under test conforms to the set flow meter related protocol and type, and the RS485 communication module 37 replies with the data, the communication success reminder module 34 reminds the production personnel through a buzzer.

[0035] The RS485 communication module 37 receives data sent by the flow meter valve control controller and transmits it to the single chip microcomputer 36. The single chip microcomputer determines whether the RS485 data meets the protocol requirements by storing relevant protocol parameters; if it meets the protocol requirements, the reply data is sent to the flow meter valve control controller through the RS485 communication module 37; if it does not meet the protocol requirements, no reply data is given.

[0036] Specifically, due to the excessive number of flow meter manufacturers, there are also many types of flow meter valve controllers. At the same time, the need to test the flow meter valve controller requires the purchase of multiple flow meter models, which greatly increases the production cost. At the same time, each type of flow meter valve controller must be connected to the corresponding flow meter by wire, which greatly increases the production time.

[0037] The flowmeter valve control controller detection device single chip microcomputer 36 stores modbus communication protocols of flowmeters of various manufacturers and models. Production test personnel can set the corresponding modbus communication protocol through the application system, and transmit it to the single chip microcomputer 36 and store it through the wireless communication module 33. Production test personnel only need to connect the flowmeter valve control controller detection device and the controller under test in a fixed connection method. After the preparation supply is completed, the flowmeter valve control controller detection device is loaded with 4 dry batteries, and the controller under test is powered on. First, the flowmeter valve control controller detection device detects that the controller under test opens the valve, and the valve opening indicator light 21 lights up; then the controller under test closes the valve, and the valve closing indicator light 22 lights up; the controller under test outputs 24V DC in turn, and the 24V DC indicator light 23 lights up; the controller under test sends data through the RS485 communication module 37 in turn, and the single chip microcomputer 36 performs data verification after receiving the data. If it meets the set protocol, the data is replied according to the protocol content.

[0038] The power supply (dry battery), indicator light module, main control circuit board, and assembly junction box proposed in this paper have a simple structure and can autonomously detect whether the controller under test is in the open valve state and the closed valve state; can autonomously detect the output of the 24V DC power supply of the controller under test; and can determine the correctness of the RS485 hardware circuit related to the controller under test by detecting the correctness of the data sent by the controller under test.
