[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] When implementing:

[0042] like Figures 2-1 to 2-3 As shown: A wireless valve control meter testing method is characterized by comprising the following steps performed in chronological order:

[0043] Step 1: Read the water meter identity: Use a scanner to scan the coded information on the surface of the wireless valve control meter and read the water meter identity;

[0044] Use the preset test program in the host computer to control the second to fourth steps;

[0045] Step 2: Wake up: Use the infrared probe to send a wake-up command to the infrared receiver on the valve control meter;

[0046] Step 3: Valve control detection: The infrared probe transmits the valve control command according to the preset program, and then detects whether the action of the valve control meter is consistent with the preset action of the valve control command: if consistent, go to step 4; if inconsistent, go to step 5;

[0047] Step 4: Remote transmission detection: Use the infrared probe to send test and data upload instructions to prompt the valve control meter to transmit the test data to the Internet of Things platform using its own NB communication module after completing the test;

[0048] Step 5. Testing completed.

[0049] Compared with the prior art, the wireless valve control meter testing method of this technical solution has the following advantages:

[0050] Under the premise of ensuring the function, performance and reliability of the wireless valve control meter products remain unchanged, the testing efficiency of the wireless valve control meter products is improved, the operating steps of the testers are reduced, the error rate is reduced, and the labor intensity is reduced.

[0051] Among them, in the first step, a scan code sticker with a test start instruction is pasted near the valve control meter to be inspected (not shown in the figure), and the second step is entered after the scanning is completed.

[0052] Compared with using physical control buttons, the above operation method can be simpler, reduce the hardware materials required for physical buttons, and simplify the structural layout of the test bench.

[0053] Moreover, after the tester has finished scanning the code of the valve control meter to be inspected, he can quickly and timely repeat the scanning operation to scan the code scanning sticker. The action is simple and continuous, and the operation efficiency is higher.

[0054] Among them, in the three steps, before the infrared probe transmits the valve control instruction according to the preset program, it also includes a reset step of using a magnetic steel to open the magnetic ball valve in the wireless valve control meter.

[0055] In this way, the magnetic steel can be used to reset the ball valve, prepare for the subsequent valve control test, and make the valve control test results more authentic.

[0056] Wireless valve control meter test method, using wireless valve control meter test bench (such as Figures 2-4 to 2-7 The wireless valve control meter test bench comprises a host computer, a scanner and an infrared probe, wherein the scanner is electrically connected to the host computer and is used to scan the coded information on the wireless valve control meter; the infrared probe is electrically connected to the host computer and is used to issue a valve opening, valve closing or test instruction to the wireless valve control meter;

[0057] It also includes a magnetic steel, which is used to be close to the magnetic attraction position on the wireless valve control meter, which can use magnetism to open the magnetic ball valve in the wireless valve control meter; it is characterized in that it also includes:

[0058] A material unloading tool, wherein the material unloading work can be used to stably place the wireless valve control meter;

[0059] A transfer mechanism, wherein the material unloading tool is fixedly installed on the moving platform of the mobile mechanism, and the mobile mechanism is used to drive and make the infrared transceiver on the wireless valve control meter placed on the material unloading tool face or stay away from the infrared probe;

[0060] A magnetic steel driving mechanism, wherein the magnetic steel driving mechanism has a controllable telescopic portion, on which the magnetic steel is fixedly mounted so that the magnetic steel can be brought close to or away from the wireless valve control meter placed on the unloading tooling;

[0061] A lower computer, the lower computer is electrically connected to the upper computer and to the magnetic steel driving mechanism, and is used to drive and control the transfer mechanism and the magnetic steel driving mechanism;

[0062] The valve opening and closing detection mechanism is electrically connected to the upper computer, and the detection head of the valve opening and closing detection mechanism is along the water pipe axis of the wireless valve control meter and directly faces the perforation of the opening and closing ball of the ball valve.

[0063] The working principle of the wireless valve control meter test bench is as follows:

[0064] First, manually place the wireless valve control meter to be inspected into the unloading tooling (this step is also convenient for using a manipulator to combine with a conveyor belt to realize automatic loading later);

[0065] Secondly, a manual handheld barcode scanner scans the coded information on the wireless valve control meter. After scanning the barcode, the host computer enters the water meter information and inputs the start detection command to the host computer (this step is also convenient for subsequent arrangement and automatic barcode scanning mechanism to improve the scanning efficiency);

[0066] Subsequently, the upper computer transmits a signal to the lower computer and completes the following steps in sequence: the transfer mechanism performs the feeding action (feeding in the material discharging tooling and making the infrared transceiver on the wireless valve control meter face the infrared probe) → the magnetic steel driving mechanism performs the approaching action (the magnetic steel is close to the wireless valve control meter, and the magnetic ball valve in the wireless valve control meter is opened) → the magnetic steel driving mechanism performs the moving away action, the infrared probe issues a valve closing command, and waits for the wireless valve control meter to act → repeats the approaching action of the magnetic steel driving mechanism → the magnetic steel driving mechanism performs the moving away action, the infrared probe issues a valve opening command, and waits for the wireless valve control meter to act → NB network test → uploading test data through the NB network → the transfer mechanism performs the moving away action

[0067] Finally, materials are manually taken and comprehensive testing of the wireless valve control meter is completed.

[0068] The advantages of the wireless valve control meter test bench are:

[0069] 1. The functional components of the entire solution are complete, and most of the automated tests can be basically realized through the test bench of this technical solution. The testers only need to load and take out materials, which greatly reduces the labor intensity of the testers and improves the detection efficiency.

[0070] 2. This technical solution is easier to expand and realize comprehensive testing of multiple wireless valve control meters at the same time, further doubling the detection efficiency.

[0071] From the above, the above-mentioned wireless valve control meter test bench can help the smooth implementation of the wireless valve control meter test method.

[0072] Wherein, a single unloading tool, a single set of magnetic steel driving mechanism and a single set of valve opening and closing detection mechanism together constitute a single set of test components;

[0073] The transfer mechanism comprises a synchronous belt linear module and a support plate of a strip plate structure, the length direction of the support plate is perpendicular to the length direction of the synchronous belt linear module, the support plate is fixedly mounted on the upper end surface of the moving platform of the synchronous belt linear module, and a plurality of sets of the detection units are arranged at intervals on the upper surface of the support plate along the length direction; the lower computer is electrically driven and connected to the motor on the synchronous belt linear module through a motor driver;

[0074] The infrared probe is fixedly installed above the test component through a probe supporting mechanism, and the infrared probe is arranged in a one-to-one correspondence with the test component.

[0075] The advantages of the above technical solution are:

[0076] 1. After adopting the above-mentioned transfer mechanism, multiple sets of test components can be conveniently set on the support plate. The discharge tooling in each set of test components can place a single wireless valve control meter to be tested. Therefore, this solution can test multiple wireless valve control meters at the same time, which doubles the test efficiency.

[0077] 2. At the same time, the moving mechanism can drive the synchronous belt linear module to make the wireless valve control meters to be tested in all the unloading tools on the support plate face the corresponding infrared probes (complete the transmission of instructions and data) or stay away from them (then move closer to the tester, making it easier for the tester or the robot to load the materials).

[0078] 3. The synchronous belt linear module can more accurately control the reciprocating movement position along the straight line direction. In this way, the infrared receivers on different types of wireless valve control meters can correspond to the infrared probes by accurately controlling the movement position, thereby improving the versatility and practicality of the test bench and reducing the cost of the test bench and testing costs for various types of meters.

[0079] Wherein, the probe support mechanism includes a linear guide rail, a slide table and a support block;

[0080] The length direction of the linear guide is parallel to the length direction of the support plate and is fixedly installed in suspension through a support structure. The slide can be slidably mounted on the linear guide. The slide is fixedly installed with a long strip of support block. The length direction of the support block is parallel to the length direction of the linear guide. The infrared probe is fixedly installed on the support block.

[0081] By adopting the above-mentioned probe support mechanism, precise lateral adjustment of the slider on the linear guide rail can be achieved, so that the infrared probe on the support block can be directly opposite to the infrared receivers on various types of wireless valve control meters in the horizontal direction, so that it is convenient to use in combination with the synchronous belt linear module. By precisely controlling the longitudinal movement position and the lateral position, the infrared receivers on different types of wireless valve control meters can all be directly opposite to the infrared probe to realize infrared communication, thereby improving the versatility and practicality of this test bench.

[0082] Wherein, the magnetic steel driving mechanism comprises a magnetic steel driving cylinder and a magnetic steel support;

[0083] The magnetic steel driving cylinder is fixedly mounted on the upper plate surface of the support plate, the outer end of the push rod of the magnetic steel driving cylinder is fixedly mounted with the magnetic steel support, the magnetic steel support is in an L-shaped structure in a top view, and the outer side of the L-shaped structure is fixedly connected to the push rod, and the longitudinal part and the transverse part of the inner side of the L-shaped structure are each fixedly mounted with a magnetic steel;

[0084] The magnet arranged on the longitudinal part inside the L-shaped structure is used to approach and move away from the magnetic attraction position arranged in the width direction of the wireless valve control meter, and the magnet arranged on the transverse part inside the L-shaped structure is used to approach and move away from the magnetic attraction position arranged in the length direction of the wireless valve control meter.

[0085] The advantages of the above magnetic steel drive mechanism are:

[0086] 1. Save space, compact structure, small size, easy to install.

[0087] 2. The magnetic steel support is L-shaped in the top view, so that it has higher structural strength through the bending structure;

[0088] At the same time, what is even more clever is that magnets are fixed at the horizontal and vertical positions on the inner side of the L-shaped structure of the magnetic steel support. In this way, it can be used in conjunction with two types of wireless valve control meters with magnetic positions set in the width direction or magnetic positions set in the length direction to realize the magnetic opening of the magnetic ball valve by the magnet, thereby achieving versatility and versatility, and helping to further reduce the cost of the test bench.

[0089] Wherein, the valve opening and closing detection mechanism includes a distance measuring sensor, which is fixedly mounted on the upper surface of the support plate, and the detection head of the distance measuring sensor is along the water pipe axis of the wireless valve control meter and directly facing the perforation of the opening and closing ball of the ball valve.

[0090] The distance measuring sensor is used as the valve opening and closing detection mechanism, and different values ​​can be measured when the ball valve of the wireless valve control meter is opened and closed to judge the opening and closing state of the valve control, thereby smoothly realizing the valve control opening and closing detection.

[0091] During implementation, the preferred distance measuring sensor is an infrared distance measuring sensor or a laser distance measuring sensor.

[0092] Example 1 of the wireless valve control meter test bench, single row of test stations (not shown in the figure):

[0093] In this embodiment, the number of the transfer mechanism is one set, that is, the number of the support plate is one piece.

[0094] During implementation, a structure in which 10 workstations are arranged at intervals on the support plate may be adopted.

[0095] Embodiment 2 of the wireless valve control meter test bench, double-row test stations (such as Figure 2-4 to Figure 2-6 shown):

[0096] In this embodiment: the number of the transfer mechanisms is two, that is, the number of the support plates is two;

[0097] The wireless valve control meter test bench has two steps in the height direction, and a set of the transfer mechanism is fixedly installed on the horizontal surface of each step, and the infrared probe is fixedly installed on the vertical surface of each step.

[0098] The advantages of the above structural layout are:

[0099] 1. It can make full use of the vertical space, reduce the footprint of the test bench, improve compactness and flexibility in narrow ground layout.

[0100] 2. Both the horizontal and vertical surfaces of each step can be used as installation surfaces to fully utilize the structure;

[0101] 3. The setting of two-step support surface makes the top of each step empty, which is convenient for material placement and material collection; at the same time, the height of each step can also be better designed to facilitate the testers or manipulators to place and collect materials comfortably and smoothly, reducing labor intensity.

[0102] Among them, the wireless valve control meter test bench also has a third step higher than the two steps, an electrical cabinet is fixedly installed on the horizontal step surface of the third step, the upper computer and the lower computer are fixedly installed in the electrical cabinet, and a display screen is arranged on the front side of the electrical control cabinet.

[0103] The arrangement of the third step and the electrical cabinet mentioned above also has the advantages of "making full use of the vertical space, reducing the footprint of the test bench, improving compactness and flexibility of use in narrow ground arrangements".

[0104] In addition, it is also convenient for testers to observe the display screen to check the test status and progress, so as to better ensure the smooth progress of the test.

[0105] In summary, the wireless valve control meter test bench using the two embodiments can make the entire test process of the wireless valve control meter simpler, easier for employees to operate, significantly improve efficiency, greatly reduce labor intensity, and make the test process more intelligent. The specific operation process is:

[0106] Workstation preparation → product clamping → software testing → testing completed.

[0108]

[0109] The solution of the preferred embodiment 2 improves the comprehensive test efficiency by about 55% compared with the current one, and the number of testers is reduced from 3 to 1, which has a more significant effect of reducing costs and increasing efficiency.

[0110] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the technical solution should also be deemed to fall within the scope of protection required by the claims.
