Description

Technical Field

[0001] This invention relates to the field of automatic testing technology, and specifically to a fully automatic testing device and system for a smart water meter controller. Background Technology

[0002] Smart water meters primarily rely on microelectronics, sensing technology, smart IC card technology (such as RFID), and Internet of Things (IoT) communication technology (such as NB-IoT) to convert mechanical flow data collection into electronic signals, enabling remote data transmission and automated management. Essentially, they are digital metering devices that overcome the limitations of manual meter reading compared to traditional mechanical water meters. With the development of IoT technology, smart water meters are becoming a core component of smart city water systems, driving the digital upgrade of water resource management.

[0003] For example, in patent application CN102496259A, entitled "Internet of Things Smart Water Meter and Its Management System," the water meter has a water inlet and an outlet. A valve assembly and a water flow measuring device are installed at the water inlet. The water meter also includes a CPU controller connected to the water flow measuring device. The CPU controller reads metering information from the water flow measuring device and subtracts the initial value stored in the EPPROM memory based on the data. The CPU controller is also connected to the valve assembly via a valve assembly control circuit to control the opening and closing of the valve assembly. The water meter also includes a data transmission module, which is connected to... The CPU controller transmits data to the data acquisition unit via a data transmission module. The data acquisition unit and the water meter form an Internet of Things (IoT) network. The data acquisition unit is also connected to the Internet and transmits data to the remote control terminal via the Internet. The data acquisition unit transmits the meter-end data received from the CPU controller of the water meter via the IoT to the remote control terminal via the Internet, or transmits the control commands received from the remote control terminal via the Internet to the CPU controller of the terminal water meter via the IoT. The CPU controller sends control commands to the valve component control circuit and the water flow measurement device according to the control commands, and provides feedback to the remote control terminal via the IoT.

[0004] This invention application integrates smart water meters into an Internet of Things (IoT) using data acquisition devices. This allows remote control terminals to directly acquire meter information or receive feedback from smart water meters within the IoT network via the internet. The remote control terminals manage and monitor the operating status of the smart water meters in a one-to-many manner. A stable internet network built through multi-level data acquisition devices ensures stable signal transmission, guaranteeing that each smart water meter in the IoT network can be controlled in real time. This facilitates remote meter reading and remote water price adjustment. Furthermore, the IoT smart water meter and its management system provided by this invention have a simple structure, and their functions are based on IoT technology, making them suitable for installation and use in various regions with a wide range of applications.

[0005] Currently, when testing the controller of a smart water meter, it is necessary to manually connect the input and output wires of the controller, which increases the workload of the testers and greatly reduces the testing efficiency of the smart water meter controller, thus exhibiting certain defects.

[0006] In view of the above, this application is hereby submitted. Utility Model Content

[0046] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0047] Example 1:

[0048] like Figures 1 to 5 As shown, an embodiment of the present invention provides a fully automatic testing device for a smart water meter controller, comprising:

[0049] Test base 1, which is used to provide a test platform.

[0050] Positioning clamp 2 is fixedly mounted on the test base 1 and is used to clamp and fix the controller to be tested.

[0051] Test component 3 is vertically slidably mounted on the test base 1 via positioning frame 21. Test component 3 is electrically connected to the input and output terminals of the controller under test via lifting and lowering movement.

[0052] The lifting adjustment component 4 is movably mounted on the positioning frame 21 and is used to drive the test component 3 to rise or fall.

[0053] In this embodiment, when the controller to be tested needs to be tested, the controller to be tested is placed on the positioning fixture 2 and clamped and fixed using the positioning fixture 2. Then, the height of the test component 3 is adjusted using the lifting adjustment component 4 to complete the electrical connection between the test component 3 and the controller to be tested. Finally, the test component 3 tests the controller to be tested, and the quality of the controller to be tested is determined based on the test results.

[0054] Unlike existing technologies, this invention utilizes the positioning fixture 2 to quickly position and fix the controller to be tested, while simultaneously using the lifting and lowering of the test component 3 to complete the construction of the test circuit. This enables rapid testing of the controller to be tested, greatly improving the testing efficiency of the controller. It features a simple structure and convenient operation.

[0055] Furthermore, the positioning fixture 2 includes:

[0056] The fixing frame 5 is fixedly installed on the test base 1.

[0057] A square positioning plate 6 is fixedly mounted on the fixed frame 5, and the square positioning plate 6 has a moving groove 9 along the diagonal direction.

[0058] A drive screw 7 is rotatably mounted on the bottom of the fixed frame 5. The drive screw 7 includes a drive rod, both ends of which are provided with drive threads, and the drive threads at both ends of the drive rod rotate in opposite directions.

[0059] Two positioning clamping frames 8 are symmetrically arranged. The two positioning clamping frames 8 are slidably arranged in the moving slide groove 9 through the drive column 23, and the bottom of the drive column 23 is threadedly connected to the drive screw 7.

[0060] In this embodiment, the middle part of the drive screw 7 is connected to an adjustment handle 10 via a worm gear transmission. The worm gear includes a drive worm 11 and a transmission worm wheel 12. The drive worm 11 is rotatably mounted on the fixed frame 5, and the transmission worm wheel 12 is fixedly mounted on the drive screw 7, and the transmission worm wheel 12 is meshed with the drive worm 11.

[0061] When clamping and fixing the controller to be tested, first, place the controller to be tested between the two positioning clamping frames 8. Then, rotate the adjusting handle 10. Under the transmission of the worm gear, the drive screw 7 rotates. The drive rod threadedly connected to the drive screw 7 is restricted by the inner wall of the moving slide 9 and cannot rotate with the drive screw 7. The drive column 23 and the positioning clamping frames 8 can only move together or apart along the length direction of the drive screw 7. When the two positioning clamping frames 8 move together, they clamp and fix the controller to be tested. When the two positioning clamping frames 8 move apart, they release the clamping and fixing of the controller to be tested. The movement direction of the drive column 23 is controlled by the rotation direction of the adjusting handle 10.

[0062] In this embodiment, the adjusting handle 10 and the drive screw 7 are connected by a worm gear transmission. A worm gear is a transmission device that transmits motion and power between intersecting shafts through the cooperation of a drive worm 11 and a transmission worm wheel 12. Its basic structure includes a helical drive worm 11 and a transmission worm wheel 12 similar to a helical cylindrical gear. The drive worm 11 is usually set as the driving component, and its shape is similar to a bolt, while the worm gear is quite similar to a helical cylindrical gear. The self-locking principle of the worm gear transmission is based on the principle of friction. When the lead angle of the drive worm 11 is less than the equivalent friction angle between the meshing teeth, the transmission can achieve self-locking. This means that under the action of external power, the drive worm 11 cannot drive the transmission worm wheel 12 to rotate, so that the two positioning clamping frames 8 are stably held in the current position, thereby stably clamping and fixing the controller to be tested.

[0063] In a specific real-time example, the positioning clamping frame 8 is configured in an L-shape, and the two positioning clamping frames 8 together form a closed square. When clamping and fixing the controller under test, the two positioning clamping frames 8 close synchronously, and the controller under test is pushed to the center of the square positioning plate 6 through the two sides of the L-shape of the positioning clamping frame 8. This not only clamps and fixes the controller under test, but also moves the controller under test to the center position, facilitating the electrical connection with the controller under test through the test component 3.

[0064] Furthermore, the test component 3 includes:

[0065] The slide rail 13 is fixedly installed on the positioning frame 21.

[0066] Positioning slide 14 is slidably mounted on slide rail 13.

[0067] The test plate 15 is fixedly installed on the positioning slide 14. The test plate 15 has several fixing holes 16, and test probes 17 are inserted into the fixing holes 16.

[0068] In this embodiment, when the positioning slide 14 slides down the slide rail 13, the test probe 17 on the test board 15 comes into contact with the input and output terminals of the controller under test, completing the construction of the test circuit. The input terminals include at least a power supply and a control keyboard, and the output terminals include at least an actuator. The test result of the controller under test is determined by comparing the input and output signals.

[0069] The fixing holes 16 are provided through the test plate 15 and are evenly distributed on it. The test probes 17 are inserted into the fixing holes 16, and their tails are electrically connected to output wires 18. The output wires 18 are used to connect to the power supply, control keyboard, and actuators. During testing, depending on the position of the input / output terminals of the controller under test, the test probes 17 can be inserted into the fixing holes 16 at different positions for precise alignment with the input / output terminals of the controller under test.

[0070] In one specific embodiment, a limiting platform 19 is fixedly provided at the bottom of the slide rail 13. The limiting platform 19 is used to limit the descent height of the positioning slide 14. During the descent of the positioning slide 14, in order to prevent the test probe 17 from directly hitting the square positioning plate 6, the limiting platform 19 is fixedly provided at the bottom of the slide rail 13 to limit the excessive descent of the positioning slide 14, thus playing a certain protective role.

[0071] Furthermore, the lifting adjustment member 4 includes:

[0072] A lifting handle 20, the end of which is rotatably mounted on the positioning frame 21;

[0073] The transmission rod 22 has one end movably connected to the middle of the lifting handle 20, and the other end rotatably connected to the positioning slide 14.

[0074] In this embodiment, when the test component 3 needs to be adjusted in height, lifting the lifting handle 20 upward or pressing it downward will drive the positioning slide 14 to move upward or downward through the transmission rod 22, thereby realizing the electrical connection and disassembly between the test component 3 and the controller under test.

[0075] Working principle:

[0076] When testing the controller under test, first, place the controller under test on the two positioning clamping frames 8, and rotate the adjusting handle 10 to close the two positioning clamping frames 8. During the closing process, the controller under test is pushed towards the center of the square positioning plate 6, and finally, the two positioning clamping frames 8 clamp and fix the controller under test. Then, according to the position of the input and output terminals of the controller under test, adjust the position of the test probe 17 and insert it into the corresponding fixing hole 16 so that the test probe 17 is directly above the input and output terminals of the controller under test. Finally, gently press the lifting handle 20 to lower the test plate 15 until the test probe 17 abuts against the input and output terminals of the controller under test, completing the electrical connection. At this point, the quality of the controller under test can be determined based on the input and output signals of the controller under test.

[0077] Example 2:

[0078] This invention also discloses a fully automatic testing system for a smart water meter controller, employing the aforementioned fully automatic testing device for a smart water meter controller, comprising:

[0079] A power supply module, which supplies power to the controller under test.

[0080] An input module is connected to the controller under test and is used to input signals to the controller under test.

[0081] An output module is connected to the controller under test, and the output module 25 is used to output signals to the controller under test.

[0082] The test alarm module is connected to the controller under test, and the test alarm module indicates the test result through audible and visual alarms.

[0083] In this embodiment, the power module and input module are connected to the test probe via output wires, and the output module and test alarm module are connected to the test probe 17 via output wire 18. During the descent of the test component 3, the test probe 17 contacts the input and output terminals of the controller under test, completing the electrical connection. The quality of the controller under test is determined by comparing the input and output.

[0084] Compared with the prior art, the present invention has at least the following beneficial effects:

[0085] This invention utilizes a positioning fixture to quickly position and fix the controller under test, while simultaneously using the lifting and lowering of the test components to complete the construction of the test circuit. This enables rapid testing of the controller under test, greatly improving the testing efficiency. It features a simple structure and convenient operation.

[0086] Furthermore, the lifting component drives the test component to move up and down, and at the same time, the positioning fixture centers the controller, which can quickly complete the electrical connection with the controller's input and output, thereby improving the testing efficiency of the smart water meter controller.

[0087] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
