In order to ensure reliable operation within the minimum ten-year life cycle, manufacturers need to test and verify a large number of designed products of various models. The existing reliability verification method of internet of things gas meter mainly checks and tests each component of the gas meter through manual operation. Although this method can verify the reliability of the gas meter, it is inefficient and prone to human error. In addition, the existing gas meter test tool can usually only verify one or several components of the gas meter, and cannot comprehensively verify the reliability of the entire gas meter.

[0029] refer to Figure 1 and Figure 2 This utility model provides a tooling for reliability verification of IoT gas meters, including a housing 1, a power supply component 2, an electromechanical simulation component 3, and a control component 4. The power supply component 2, the electromechanical simulation component 3, and the control component 4 are all installed inside the housing 1. The electromechanical simulation component 3 includes a motor valve 31, a stepper motor 32, and a counter 33. The motor valve 31 is adapted to implement valve opening and closing commands. The stepper motor 32 is adapted to mesh with the counter 33 and simulate the operation of the smart gas meter's mechanism.

[0030] In this embodiment, the present application can remotely execute automated test commands. The stepper motor 32 simulates the operation of the smart gas meter's mechanism, driving the counter 33 gears to operate, thereby detecting the metering accuracy and stability of the product. With the help of some valve closing strategies, it can simulate functions such as micro-leakage detection and overcurrent detection of the gas meter. At the same time, it can run automatically for a long time to verify the reliability and electrical performance of the motor valve 31. This automated testing method can not only greatly improve testing efficiency and reduce human error, but also improve the accuracy and reliability of smart gas meter testing.

[0031] Specifically, the enclosure 1 includes a base plate 11, a lower partition 12, and an upper partition 13 arranged vertically at intervals. The power supply assembly 2 is mounted above the base plate 11, the electromechanical simulation assembly 3 is mounted above the lower partition 12, and the control assembly 4 is mounted above the upper partition 13. The power supply assembly 2, the electromechanical simulation assembly 3, and the control assembly 4 are arranged vertically and interconnected, resulting in a more rational tooling layout with clear division of labor for each layer. This facilitates faster local operation for users and also makes future maintenance easier. Furthermore, the various panels of the enclosure 1 are secured with screws to ensure the overall stability of the enclosure 1.

[0032] The electromechanical simulation component 3, consisting of a motor valve 31, a stepper motor 32, and a counter 33, is fixed to the lower partition 12 with screws. The motor valve 31 simulates real valve opening and closing commands. The stepper motor 32 is suitable for simulating the movement of a smart gas meter's mechanism, and the counter 33 is suitable for meshing with the gears of the stepper motor 32. In the fixture, a high-precision stepper motor 32 is used to simulate the movement of the smart gas meter's mechanism, driving the counter 33 to rotate, thereby detecting the metering accuracy and stability of the product. This method can automatically execute test commands, greatly improving testing efficiency, reducing the influence of human factors, and improving test accuracy. By designing and implementing some valve-closing strategies, the reliability and electrical performance of the motor valve 31 are verified. This method can comprehensively evaluate the performance of the gas meter, not only in terms of metering accuracy and stability, but also to verify the reliability of other key components of the gas meter.

[0033] The power supply assembly 2 includes a switching power supply 21, a power strip 22, and a digitally controlled voltmeter and ammeter 23. The switching power supply 21 and the power strip 22 are mounted on the base plate 11. The enclosure 1 also includes a front plate 14 and a sloping baffle 141. The front plate 14 is located at the front end of the base plate 11, and the sloping baffle 141 is located at the top of the front plate 14 and tilted inwards towards the enclosure 1. The digitally controlled voltmeter and ammeter 23 is mounted on the sloping baffle 141. In this embodiment, a digital voltmeter and ammeter are used, which can monitor the working status of the equipment in real time, promptly detect and handle faults, and improve the stability and reliability of the equipment. The power supply assembly 2 can provide three voltage specifications: 220V, 12V, and 5V, which can be displayed intuitively by the digitally controlled voltmeter and ammeter 23. The output voltage can also be adjusted as needed. The sloping baffle 141 is located at the top of the front plate 14 and tilted inwards towards the enclosure 1, making it easier to observe the digitally controlled voltmeter and ammeter 23 on the sloping baffle 141, which is more in line with the user's viewing angle. Preferably, the digitally controlled voltmeter and ammeter 23 is fixed to the inclined baffle 141 by four clips. In a modified embodiment, the digitally controlled voltmeter and ammeter 23 can also be fixed to the inclined baffle 141 by other fixing methods. It is worth noting that the top of the inclined baffle 141 does not exceed the lower partition 12, so that the inclined baffle 141 does not affect the operation of the electromechanical analog component 3 on the lower partition 12. The inclined baffle 141 can also be set horizontally, and this application does not further limit it.

[0034] The control component 4 includes a micro industrial control host 41, a hub 42, and a serial port adapter board 43. The micro industrial control host 41 controls each interface through the hub 42 and the serial port adapter board 43. In this embodiment, the use of the micro industrial control host 41 enables remote real-time data processing and analysis, improving the accuracy and efficiency of the test. Furthermore, since the verification fixture of this application can automatically execute test commands, it reduces the influence of human factors, avoids misjudgments or omissions, and improves the accuracy of the test. In summary, the intelligent gas meter reliability verification fixture of this application, compared with the prior art, has advantages such as high automation, comprehensive testing, time saving, and reduced human error, making it an ideal solution for intelligent gas meter reliability verification. The micro industrial control host 41 is the core control component. External commands can be remotely sent to the micro industrial control host 41 via the network port, and the host then controls each interface according to the commands through the hub 42 and the serial port adapter board 43. The hub 42 is preferably a USB hub. The USB hub design allows for easy connection of multiple devices, enabling data sharing and transmission, further improving testing efficiency and convenience.

[0035] It is worth noting that, since the verification fixture of this application can remotely execute automated test instructions, a large number of tests can be completed in a short time, which greatly saves test time and improves production efficiency.

[0036] Furthermore, the electromechanical simulation component 3 also includes a motor bracket 34 and a relay 35. The motor bracket 34 is located above the lower partition 12, and the stepper motor 32 is mounted on the motor bracket 34, so that the stepper motor 32 is fixed at a certain height. The relay 35 connects the motor valve 31 and the stepper motor 32.

[0037] Specifically, the motor valve 31 is used to simulate real valve switching commands. The stepper motor 32 is fixed at a certain height via a stepper motor 32 bracket. Gears are installed below the stepper motor 32. Through gear meshing, the gears of the counter 33 are driven to rotate, ultimately converting into the rotation of the digit wheel. An accurate correspondence is established between the rotational speed of the stepper motor 32 and the gas consumption of the IoT gas meter through a calculation formula, thus realizing the simulation of various flow rates. The relay 35 is a multi-channel specification, which can control the power-on and power-off of multiple devices to achieve program control. It is worth noting that the counter 33 can also be installed on the lower partition 12 via a counting bracket, so that the counter 33 can also be fixed at a certain height, allowing the gears below the stepper motor 32 to mesh with the gears of the counter 33. This application does not further limit the specific structure of the motor bracket 34 and the counting bracket, as long as the stepper motor 32 and the counter 33 are suitable for meshing connection.

[0038] Furthermore, it also includes a display component 5, which includes a movable plate 51 and a touch screen. The movable plate 51 is movably mounted on the housing 1, and the touch screen is disposed on the movable plate 51.

[0039] Preferably, the box body 1 includes a right side panel 15, a left side panel 16 and a rear panel 17. The right side panel 15 and the left side panel 16 are disposed on both sides of the box body 1, and the rear panel 17 is disposed on the rear side of the box body 1. The movable panel 51 can be flipped and disposed on the top of the rear panel 17 and is located opposite to the top of the box body 1 via a flipping component.

[0040] In this embodiment, the display component 5 is located on the top layer of the housing 1 and can be flipped and installed on the housing 1. When local operation is required, the touch screen of the movable plate 51 can be opened for use. When not in use, the screen can be closed, which occupies little space and also has the functions of protecting the screen and preventing dust from falling on it.

[0041] Specifically, the display component 5 includes a movable plate 51 and a touch screen. The movable plate 51 serves as the outer frame of the touch screen, which is located below it. The movable plate 51 is connected to the back panel 17 by two stainless steel hinges. When local operation is required, the touch screen can be opened for use; when not in use, the movable plate 51 and touch screen can be closed, minimizing space usage and protecting the touch screen from dust. The housing 1 is made of insulating material. The movable plate 51 is preferably made of bakelite. This structural design effectively prevents electrostatic interference and improves the stability and reliability of the equipment. The back panel 17 has several cable routing holes through which the power supply cable of the power assembly 2 is led out. It is worth noting that in this embodiment, the movable plate 51 is flipped up and down and disposed on the top of the box 1. In a modified embodiment, the movable plate 51 can also be flipped left and right and disposed on the side wall of the box 1. The movable plate 51 can even be slidably installed inside the box 1. This application does not further limit the flipping structure and movement mode of the movable plate 51, as long as the touch screen of the movable plate 51 can be unfolded when in use and can be covered when not in use.

[0042] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
