Therefore, they should not be construed as limitations on this application.

[0024] In some high-voltage / medium-voltage power line (above 10kV) power terminal equipment, due to on-site environmental factors such as tree obstruction, building interference, or complex electromagnetic environment, the network signal coverage is insufficient or the quality is unstable, resulting in the installed terminal equipment having no 4G signal or extremely poor signal, making it impossible to communicate with the backend. To address this, this embodiment proposes a data interaction device for a medium-voltage power line carrier communication system, which uses the medium-voltage power line itself as the communication medium to realize communication between the terminal equipment and the backend.

[0025] The following is combined with Figures 1 to 4 This application describes a data interaction device for a medium-voltage power line carrier communication system.

[0026] refer to Figures 1 to 3 The data interaction equipment for the medium-voltage power line carrier communication system includes: host 1, slave 2 and isolation coupler 3.

[0027] The host 1 includes a host housing 11, a host main control board 12, a host carrier connector 13, a host communication unit 14, a host power connector 15, and a human-machine interaction unit 16. The host housing 11 is provided with a main receiving cavity 17. The host main control board 12 is fixedly installed in the main receiving cavity 17. The host carrier connector 13, the host communication unit 14, the host power connector 15, and the human-machine interaction unit 16 are all electrically connected to the host main control board 12. The host carrier connector 13 is used to connect to the power line. The host communication unit 14 is used to communicate with the backend. The human-machine interaction unit 16 has an operation part that can be triggered by a person. The human-machine interaction unit 16 is used to display key information such as device operating status, signal strength, and communication quality. Slave device 2 includes slave housing 21, slave main control board 22, slave carrier connector 23, slave communication unit 24, and slave power connector 25. Slave housing 21 is provided with slave receiving cavity 26. Slave main control board 22 is fixedly installed in slave receiving cavity 26. Slave carrier connector 23, slave communication unit 24, and slave power connector 25 are all electrically connected to slave main control board 22. Slave carrier connector 23 is used to connect to power line. Slave communication unit 24 is used to communicate with terminal equipment. The isolation coupler 3 is provided in multiple ways. One isolation coupler 3 is fixedly connected to a host carrier connector 13 or a slave carrier connector 23. The isolation coupler 3 is used to provide a high-frequency signal path and block power frequency current.

[0028] In use, the host carrier interface is connected to the isolation coupler 3, which is connected to the power line. The host 1 communicates with the backend through the host communication unit 14. The slave carrier connector 23 is connected to the isolation coupler 3, which is connected to the power line. The slave is installed near the terminal device and communicates with the terminal device through the slave communication unit 24. The slave communication unit 24 transmits the collected data to the slave master control board 22. After data analysis, the slave master control board 22 couples the data signal through the isolation coupler 3, transmits it through the power line to the isolation coupler 3 connected to the host 1 for decoupling, and then uploads the data signal to the backend through the host communication unit 14. At the same time, it receives control commands issued by the backend and transmits them to the corresponding slave 2 through the power line. Multiple slave 2s can be set up, and multiple slave 2s communicate with one host 1. One host 1 can communicate with multiple backends.

[0029] The human-computer interaction unit 16 is a touch screen or a screen plus buttons, etc. Its core is that users can intuitively view key information such as device operating status, signal strength, and communication quality, and perform operations such as parameter setting and fault query, thereby improving the convenience and efficiency of use.

[0030] In summary, by configuring host 1, slave 2, and isolation coupler 3, and using a medium-voltage power line as the medium connecting slave 2 to host 1, the data signals from the terminal devices are transmitted to host 1 via stable wired transmission. Host 1 then transmits the data to the backend, solving the problem of poor network signal quality due to environmental factors, which prevents direct data transmission over the network. This device not only improves the stability of data transmission but also reduces dependence on the external network environment.

[0031] Specifically, the host communication unit 14 includes a host Ethernet port 141, a SIM card slot 142, and an antenna 143. The host Ethernet port 141, the SIM card slot 142, and the antenna 143 are all fixedly mounted on the host housing 11. The host Ethernet port 141 is used for wired communication with the backend. The SIM card slot 142 is used to set the SIM card so that the SIM card can communicate wirelessly with the backend through the antenna 143. The SIM card slot 142 is also used for setting the TF card. The configuration of the host Ethernet port 141, SIM card slot 142, and antenna 143 enables two connection methods for communication between the host 1 and the backend. The first is a direct wired connection via the host Ethernet port 141. Wired networks offer high transmission speeds and stability, making them suitable for scenarios with high real-time data transmission requirements and wired network deployment capabilities, such as centralized monitoring areas in urban power grids. The second method utilizes a SIM card and antenna 143 to achieve remote communication with the backend via a mobile communication network. This method is suitable for applications where the device is close to a signal base station and cabling is difficult. The device transmits data collected by the device to the backend via the mobile network and simultaneously receives control commands from the backend. The SIM card slot 142 also provides a TF card slot, allowing data exchanged between the slave 2 and the backend to be stored on the TF card. When the connection between the device and the backend fails or data backup is required, the TF card can save critical data to prevent loss. Once the network is restored or data maintenance is performed, the data on the TF card can be uploaded to the backend for analysis and processing. The slave communication unit 24 is an Ethernet port, which is mounted on the slave housing 21. The slave communication unit 24 is used for wired communication with the terminal device. The slave device 2 can realize wired data transmission with the terminal device through the slave communication unit 24. In practical applications, the slave device 2 is usually installed close to the terminal device and directly connected to the terminal device through the Ethernet port, thereby ensuring the real-time performance and accuracy of data transmission.

[0032] Based on the practicality of data interaction, a debugging connector 18 is fixedly installed on the main control circuit board. The debugging connector 18 passes through the main unit housing 11 and allows external devices to debug the main unit 1. For example, the debugging connector 18 can be a USB interface, which connects to external devices (such as computers or USB flash drives) for wired data transmission. When it is necessary to export the data collected by the device for analysis, or to upgrade the system or software of the device, the operator only needs to connect the main unit 1 to the external device through the debugging connector 18 cable to read the data in the device or transfer upgrade files and configuration parameters to the main unit 1. This effectively avoids problems such as signal interference and data loss that may occur with wireless transmission, ensuring the accuracy and integrity of data transmission.

[0033] In practical applications, slave device 2 is installed near the terminal equipment in outdoor or complex environments, requiring maintenance operations such as troubleshooting and parameter adjustment during long-term operation. Therefore, a maintenance connector 27 is fixedly installed on the slave control circuit board. The maintenance connector 27 is fixedly mounted on the slave device housing 21, allowing external equipment to perform maintenance on slave device 2. Technicians can perform on-site maintenance on slave device 2 without disassembling the housing, effectively improving the convenience and efficiency of maintenance and ensuring the stable operation of slave device 2.

[0034] Meanwhile, to quickly determine the operating status of the master unit 1 and slave unit 2, both master unit 1 and slave unit 2 are equipped with indicator modules 4. Indicator modules 4 are used to transmit human-machine interaction information to determine the operating status of master unit 1 and slave unit 2. Specifically, the indicator module 4 on master unit 1 is connected to the master unit control board 12, and the indicator module 4 on slave unit 2 is connected to the slave unit control board 22. The indicator module 4 on master unit 1 includes a running indicator light, a network indicator light, a communication indicator light, and a carrier indicator light; the indicator module 4 on slave unit 2 includes a running indicator light, an uplink indicator light, a downlink indicator light, and a maintenance indicator light. The operation indicator light shows whether the device is in normal operating condition. When the device is working normally, the operation indicator light will flash at a preset frequency. The network indicator light indicates the connection status between the device and the network. If the connection to the network is successful, the network indicator light will be constantly on; otherwise, it will be off. The communication indicator light shows the communication status of uplink communication data. When data is being transmitted, the communication indicator light will flash regularly; when there is no data transmission, it will be off. The carrier indicator light shows the downlink carrier data communication status. The carrier indicator light will flash with data transmission and reception; when there is no data transmission, it will be off. The uplink indicator light shows the transmission and reception status of carrier communication data of slave device 2. The downlink indicator light shows the transmission and reception status of Ethernet communication data of slave device 2. The maintenance indicator light shows the communication indication during maintenance. The light guide column 5 guides the light from each indicator light to the outside of the main unit housing 11 and the slave unit housing 21, improving the display effect of each indicator light. Through these indicator modules 4, operators do not need complicated operations or professional knowledge; they can quickly and intuitively understand the operating status of the device simply by observing the status of the indicator lights, and promptly detect any faults or abnormalities in the device, thereby improving the efficiency and accuracy of equipment operation and maintenance.

[0035] The host unit 1 is typically installed outdoors. Considering the convenience of outdoor operation, the human-machine interface unit 16 adopts a screen + button configuration. Specifically, the human-machine interface unit 16 includes an interactive display screen 161, a confirmation button 162, a return button 163, and directional keys 164. These components are fixedly mounted on the host housing 11. The confirmation button 162, return button 163, and directional keys 164 constitute the aforementioned operating parts. The interactive display screen 161 provides operators with an intuitive device monitoring interface. The confirmation button 162 is used to execute the currently selected operation or confirm the input information. The return button 163 is used to cancel the current operation or return to the previous menu. The directional keys 164 facilitate the operator's selection of menu options. This design ensures convenience for outdoor operation while improving the flexibility and efficiency of device use. The physical buttons compensate for the inconvenience of pure touch operation in certain scenarios (such as when wearing gloves), enhancing operational convenience and practicality.

[0036] The isolation coupler 3, as a key component connecting the host 1, slave 2, and the power line, is a coupling capacitor in this embodiment. Coupling capacitors have advantages such as wide bandwidth, low loss, and strong anti-interference capability. They effectively block power frequency current, allowing only carrier signals to pass through, ensuring the stability and reliability of carrier communication. In power line carrier communication systems, interference from power frequency current can severely affect carrier signals, leading to signal distortion, attenuation, or even failure to transmit normally. The coupling capacitor, through its unique capacitive characteristics, isolates power frequency current from the communication system while providing a smooth transmission path for the carrier signal.

[0037] In other embodiments, magnetic inductive couplers can be used instead of capacitive couplers. Magnetic inductive couplers can clamp onto the power line like "pliers," requiring no electrical connection to the power line and eliminating the need for operators to contact high voltage. However, compared to capacitive couplers, they have lower signal injection efficiency, greater signal attenuation, and reduced communication distance. In practical applications, the appropriate choice between capacitive and magnetic inductive couplers can be made based on specific scenario requirements and cost budgets. If high communication quality is required and the installation environment allows for electrical connection to the power line, capacitive couplers are a better choice. If the installation environment is complex, operator safety is paramount, and communication quality requirements are not particularly stringent, magnetic inductive couplers can leverage their advantages of requiring no electrical connection and easy installation.

[0038] refer to Figure 1 and Figure 3 Since the main unit 1 and slave unit 2 are typically installed in outdoor environments, such as utility poles and substations, appropriate waterproof structures are necessary to ensure stable operation. Therefore, the following configuration is provided: both the main unit housing 11 and the slave unit housing 21 include a front housing and a rear housing. The front housing and the rear housing are connected to form a main receiving cavity 17 or a slave receiving cavity 26. A sealing strip 6 is provided at the connection between the front housing and the rear housing. These sealing strips 6 provide a good seal, effectively preventing dust, moisture, and other external substances from entering the equipment. In outdoor environments, dust and moisture may damage the electronic components of the equipment, affecting its normal operation and lifespan. The presence of the sealing strips 6 provides reliable protection for the equipment, improving its reliability and stability, and ensuring normal operation in various harsh environments.

[0039] refer to Figure 4 To facilitate the installation of the main unit 1 and the slave unit 2, both the main unit 1 and the slave unit 2 are provided with hook holes 7 and mounting holes 8 on their rear housings. During installation, fasteners such as nails or bolts can be fixed at the designated installation positions of the main unit 1 or the slave unit 2, allowing the larger diameter end to penetrate into the hook hole 7. This enables the main unit 1 or the slave unit 2 to be quickly suspended on the fasteners and secured through the mounting holes 8.

[0040] This embodiment also provides a host device, which is the aforementioned host 1.

[0041] This embodiment also provides a terminal device, which is the aforementioned slave device 2.

[0042] In summary, as Figures 1 to 4 The structure shown is illustrated. This medium-voltage power line carrier communication system uses data interaction equipment to achieve stable and reliable data interaction between the host 1, slave 2, and the power line. The host 1 and slave 2 are connected to the power line via a coupler, ensuring effective transmission of the carrier signal while effectively blocking interference from power frequency current, thus guaranteeing communication quality. Meanwhile, the rich interfaces and modules equipped on the host 1 and slave 2, such as the human-machine interface unit 16 and the indicator module 4, greatly facilitate the operation, monitoring, and maintenance of the equipment. Furthermore, the sealing strip 6 further enhances the adaptability and reliability of the equipment in harsh environments.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
