Description

Technical Field

[0001] This utility model relates to the field of flow measurement technology, and in particular to a multi-loop water meter data acquisition device. Background Technology

[0002] Currently, most smart IoT water meters on the market adopt a one-meter-one-terminal approach, which can effectively collect and upload water usage data for each user in a timely manner. However, this "one-meter-one-terminal approach" requires each water meter to be equipped with a terminal, resulting in high overall construction costs and a large amount of terminal maintenance.

[0003] With the development of smart IoT technology and the improvement of people's smart living standards, the market demand for smart IoT water meters has further expanded. If the form of one meter per terminal is still adopted, the construction cost and subsequent maintenance cost will be further increased.

[0004] Therefore, how to reduce the construction and maintenance costs of smart IoT water meters has become an urgent technical problem to be solved. Utility Model Content

[0005] In view of this, it is necessary to provide a multi-loop water meter data acquisition device that can reduce construction and maintenance costs by using multiple meters as a single terminal.

[0006] To achieve the above-mentioned technical effects, this utility model provides a multi-loop water meter data acquisition device, comprising:

[0007] Multiple base tables;

[0008] Multiple ball valves, the number of which is the same as the number of base meters, are used to control the on / off state of the water pipeline where the base meters are located;

[0009] The base table acquisition module is communicatively connected to all the base tables and is used to collect traffic data from the base tables.

[0010] The control module is communicatively connected to the base meter acquisition module, and is used to acquire the flow data of the multiple base meters, and generate ball valve control commands after receiving the user's touch operation;

[0011] The ball valve drive module is communicatively connected to the plurality of ball valves and the control module, and is used to control the opening and closing states of the plurality of ball valves after receiving the ball valve control command.

[0012] In one possible implementation, the device further includes:

[0014] In one possible implementation, the device further includes:

[0015] The wireless communication module is connected to the control module and is used to upload the collected data from the multiple base meters to the cloud management platform.

[0016] In one possible implementation, the wireless communication module uploads the collected data from the multiple base tables to a cloud management platform based on the LoRa protocol.

[0017] In one possible implementation, the device further includes:

[0018] A wired communication module is connected to the control module and is used to upload the collected data from the multiple base tables to the cloud management platform.

[0019] In one possible implementation, the wired communication module uploads the collected data from the multiple base meters to the cloud management platform based on the RS485 protocol.

[0020] In one possible implementation, the device further includes:

[0027] The beneficial effects of this utility model are as follows: The multi-loop water meter acquisition device provided by this utility model realizes the acquisition of base meter data and the on / off control of the pipeline where the base meter is located through a one-to-many method. Thus, multiple base meters can be managed by one terminal, thereby effectively reducing the construction cost of smart IoT water meters.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] In the description of the embodiments of this utility model, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] This utility model provides a multi-loop water meter data acquisition device, which will be described below.

[0035] Figure 1 This is a schematic diagram of one embodiment of the multi-loop water meter data acquisition device provided by this utility model, as shown below. Figure 1 As shown, the multi-loop water meter data acquisition device 100 includes:

[0036] Multiple base tables 101;

[0037] Multiple ball valves 102, the number of which is the same as the number of base meters 101, are used to control the on / off state of the water pipeline where the base meter 101 is located;

[0038] The base table acquisition module 103 is communicatively connected to all of the multiple base tables 101 and is used to acquire traffic data from the multiple base tables 101.

[0039] The control module 104 is communicatively connected to the base meter acquisition module 103, and is used to acquire the flow data of the multiple base meters 101, and generate ball valve control commands after receiving the user's touch operation;

[0040] The ball valve drive module 105 is communicatively connected to the plurality of ball valves 102 and the control module 104, and is used to control the opening and closing states of the plurality of ball valves 102 after receiving the ball valve control command.

[0041] It should be noted that by setting up a base meter acquisition module to obtain flow data from multiple base meters, it is possible to acquire flow data from multiple base meters through a single terminal, avoiding the excessive construction costs associated with a separate terminal for each meter. Furthermore, multiple ball valves correspond one-to-one with the pipelines where the base meters are located. By controlling the on / off state of multiple ball valves through the ball valve drive module, the flow of multiple pipelines containing the base meters can be controlled, enabling pipeline management. The control module, as the core processing unit, can acquire flow data from multiple base meters through the base meter communication module and send ball valve control commands to the ball valve drive module to indicate the on / off state of the multiple ball valves. Ball valve control commands can be issued by the cloud management platform through the multi-loop water meter acquisition device, or directly from the multi-loop water meter acquisition device via touch operation.

[0042] For example, in practical applications, multiple base meters correspond to multiple water users, and ball valves of the same number as the base meters can control the on / off state of the water pipeline corresponding to each base meter. First, multiple base meters generate flow data based on the actual water usage of each user. Then, the base meter acquisition module collects the flow data from multiple base meters, and the control module obtains this data from the acquisition module. The flow data from multiple base meters can be displayed directly on the multi-loop water meter acquisition device, or it can be uploaded to a cloud management platform and displayed on the management interface. Taking the display of flow data from multiple base meters on the multi-loop water meter acquisition device as an example, managers can determine whether users have completed payment and whether their water usage is abnormal by combining the displayed flow data with the payment status of multiple users. For users with outstanding payments or abnormal water usage, administrators can use a touchscreen on the multi-loop water meter data acquisition device to generate a ball valve control command, which is then sent to the ball valve drive module. Upon receiving the command, the ball valve drive module can close the ball valve on the water supply line of the user with outstanding payments or abnormal water usage, thus stopping their water supply. Similarly, once the user with outstanding payments has paid, or the user with abnormal water usage has clarified the reason for their abnormal water usage, administrators can again use a touchscreen on the multi-loop water meter data acquisition device to generate a ball valve control command, which is then sent to the ball valve drive module to open the corresponding ball valve on the water supply line.

[0043] In summary, the multi-loop water meter acquisition device provided by this utility model achieves the acquisition of base meter data and the on / off control of the pipeline where the base meter is located through a one-to-many approach. This allows multiple base meters to be managed using a single terminal, thereby effectively reducing the construction cost of smart IoT water meters. In later maintenance, only one terminal needs to be maintained, thus effectively reducing the maintenance cost of smart IoT water meters. In other words, this utility model can effectively reduce the construction and maintenance costs of smart IoT water meters.

[0066] In some embodiments of this utility model, the base meter communication module is connected to the plurality of base meters via an RJ45 interface, and the ball valve drive module is connected to the plurality of ball valves via an RJ45 interface.

[0067] It should be noted that connecting to the base meter and ball valve via the RJ45 interface is more suitable for smart IoT scenarios, enabling intelligent control of the base meter and ball valve.
