Technical Field

[0001] This utility model relates to transmission devices, and more particularly to a dual-channel transmission device for gas meters. Background Technology

[0002] With the rapid development of IoT technology, many natural gas devices are now equipped with sensors that can accurately collect users' natural gas usage data. This data is extremely valuable and can be used for intelligent analysis, helping natural gas companies optimize operations and improve service quality. However, the current communication mode of IoT devices is one-to-one, meaning data is collected from a single source and uploaded to a single user.

[0003] In the digital age, intelligent energy management is crucial for the sustainable development of various industries. Energy consumption is closely related to social operations and daily life; precise control of energy consumption is of great significance for cost reduction for enterprises and global energy conservation and emission reduction. However, with the continuous progress of the times, enterprises' demand for digital office solutions is growing. Under this trend, natural gas usage data is no longer just needed by natural gas companies; users themselves also urgently need a complete set of data to better manage energy consumption, reduce costs, and achieve more efficient office and operations. Unfortunately, current products on the market have limitations in functionality and design, failing to meet this diverse data demand and urgently requiring upgrades and innovation.

This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," "third," etc., used to describe a common object only indicate different instances of the same object, and do not imply that the objects described in this way must be in a given order, whether temporally, spatially, sequentially, or in any other way.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] This embodiment provides a dual-path transmission device for gas meters, such as... Figure 1 As shown, the device includes a corrector 1, a data acquisition cabinet 2, a natural gas user server 3, and a natural gas company server 4. In practical applications, users often need to collect data from the corrector 1 on-site. The corrector 1 is usually installed simultaneously with the gas pipeline installation and is connected to both the gas pipeline 5 and the data acquisition cabinet 2. The corrector 1 is used to calibrate and collect gas metering data to ensure the accuracy and reliability of the data, and transmits it to the data acquisition cabinet 2 to provide accurate data support for the natural gas company and users. The data includes key information such as pressure, temperature, operating flow rate, standard flow rate, operating condition cumulative flow, standard condition cumulative flow, and coefficients. In this embodiment, the corrector 1 is model EK260.

[0026] In this embodiment, the data acquisition cabinet 2 is also connected to the natural gas user server 3 and the natural gas company server 4 respectively. The data acquisition cabinet 2 is used to transmit the calibrated gas metering data to the natural gas user server 3 and the natural gas company server 4 respectively. To ensure accurate gas data for both the natural gas company and users, this embodiment employs a professional data acquisition cabinet 2. This cabinet has a sophisticated internal structure, primarily comprising a PLC controller, a first receiver / transmitter, and a second receiver / transmitter. The PLC controller, acting as the "brain" of the data acquisition cabinet 1, performs preliminary processing and logical judgments on the acquired data using existing technologies, ensuring data integrity and accuracy. Given the critical importance of data security, the PLC controller also utilizes existing security measures such as encrypted transmission to guarantee data security and confidentiality during transmission. The first receiver / transmitter connects to the natural gas user server via a network cable, transmitting the data processed by the PLC controller to the user server for user viewing. The second receiver / transmitter connects to the natural gas company server via a 485 communication cable, transmitting the data processed by the PLC controller to the company server for company viewing. The first receiver / transmitter is a SIM7600G-H model, and the second receiver / transmitter is a Zhongshan LTE-658 series model.

[0027] Given the special environment of natural gas pipelines, safety is paramount; therefore, the hardware employs a stringent explosion-proof design. Data acquisition cabinet 2 utilizes a professional explosion-proof control cabinet that complies with relevant national explosion-proof standards, effectively preventing sparks from internal electrical components from igniting external flammable and explosive gases. In terms of circuit design, an explosion-proof safety barrier is installed between the PLC controller and the corrector 1. This barrier not only isolates hazardous energy but also conditions the signal, ensuring the stability and safety of signal transmission.

[0028] After the data acquisition cabinet is set up, a data master station needs to be installed on the servers of the natural gas company and the user. The data master station is used to decrypt the sent data using existing parsing algorithms and save it to the database, providing a solid data foundation for subsequent data query and analysis.

[0029] The natural gas user server 3 and the natural gas company server 4 are equipped with display interfaces to clearly and intuitively present the collected data in the form of charts, reports, and other formats. This allows both natural gas company managers and users to easily understand the real-time status and historical trends of gas data, facilitating energy management decisions and the formulation of energy-saving strategies. It truly achieves seamless data flow from collection to application, providing strong support for intelligent energy management.

[0030] Finally, this embodiment also includes a 24V switching power supply, which is responsible for supplying power to the entire device. The power supply is equipped with a surge protection device to protect the entire device from lightning strikes and ensure its safety.

[0031] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
