[0031] As mentioned above, in the field of low-voltage distribution area data acquisition and monitoring, the current integrated terminal for distribution area status monitoring is a secondary device that integrates functions such as distribution area power supply information acquisition, equipment status monitoring, communication networking, and localized analysis and decision-making. Typically, because the intelligent integrated terminal for distribution areas has different hardware interfaces, each corresponding to a different protocol, when different hardware interfaces communicate with the central processing unit (CPU) of the intelligent integrated terminal, additional CPU resources are required to perform multiple protocol conversions on the data from each hardware interface. This results in low CPU resource utilization of the intelligent integrated terminal.

The power line carrier communication module is used to transmit data from the terminal device.

[0037] The first bus data, the second bus data, and the third bus data all conform to the target protocol.

[0038] In one embodiment of this disclosure, the main control module is the core module of the intelligent distribution area monitoring terminal, primarily implementing all software functions of the intelligent distribution area terminal. These software functions include data processing, communication processing, edge computing, and other application functions. The main control module may consist of key components such as a processor and memory, an operating system, a container engine, an edge computing software platform, and remote communication devices (wireless communication, such as 4G or Bluetooth). The remote communication devices may be wireless communication devices. For example, the remote communication devices may include at least one of the following: fourth-generation mobile communication (4G) or fifth-generation mobile communication (5G), Ethernet, Bluetooth, etc.

[0039] In one embodiment of this disclosure, the main control module is used to analyze and calculate the collected data, monitor the power consumption status of the target transformer area, and report events.

[0040] In one embodiment of this disclosure, the acquisition module can perform AC sampling of three-phase current, voltage, and zero-sequence data of the low-voltage busbar, as well as data acquisition of harmonics, electricity consumption, power factor, and other analog quantities such as RTD temperature.

[0041] In one embodiment of this disclosure, the acquisition module further includes a measurement circuit, which is connected to the metering chip. The measurement circuit may simultaneously include a current transformer signal circuit and a voltage transformer signal circuit.

[0042] In one embodiment of this disclosure, the acquisition module further includes a power supply module, which consists of a full-wave rectifier circuit, a power converter module, and a backup power supply circuit. The power supply module is used to provide DC power to the intelligent area monitoring terminal.

[0043] In one embodiment of this disclosure, the supercapacitor and auxiliary power interface can serve as a backup power circuit. When the main power supply of the intelligent area monitoring terminal fails, the backup power circuit can be automatically and seamlessly put into use to maintain the normal operation of the equipment.

[0044] In one embodiment of this disclosure, the power line carrier communication module in the data collection module supports marketing data transmission from meters, concentrators, and other devices using the 376.2, 645, and 698 protocols. The power line carrier communication module can access and transmit data via various hardware interfaces, including UART, Universal Serial Bus, and Ethernet. Furthermore, the data collection module can cooperate with other expansion modules to enable the monitoring equipment to have intelligent configuration, detection, and diagnostic capabilities.

[0045] In one embodiment of this disclosure, the power line carrier communication module is used to transmit data from the end device, which may include at least one of the following: an electricity meter, a charging pile, a switch, etc.

[0046] In one embodiment of this disclosure, the target interface includes at least one of the following: an embedded multimedia card interface, a universal serial bus interface, and an Ethernet interface.

[0047] In one embodiment of this disclosure, the first bus module, the second bus module, and the third bus module are all field-programmable gate arrays (FPGAs).

[0048] In one embodiment of this disclosure, the target bus includes an LVDS bus.

[0049] In this embodiment, the Low Voltage Differential Signaling (LVDS) bus, also known as the RS-644 interface bus, possesses powerful data throughput and real-time data transmission capabilities. This allows it to support extended data transmission for 100Mbps Ethernet and high-speed universal serial buses, as well as extended serial communication and data transmission for cross-connect, YX, and YK modules.

[0050] In one embodiment of this disclosure, the target protocol is the FASTDP-BUS link protocol.

[0051] In the embodiments of this disclosure, an FPGA can be used to implement the FASTDP-BUS link protocol, providing the main control module with an embedded multimedia card eMMC interface, a USB interface, and an Ethernet interface, as well as FASTDP-BUS bus protocol data transmission based on the eMMC interface. Simultaneously, it can provide the extended slave modules with a bus interface based on an LVDS chip. In this way, each module can be connected to the LVDS bus, ensuring bus reliability and providing flexible access interfaces without being limited by the CPU interface.

[0052] It should be noted that, when the target protocol is the FASTDP-BUS link protocol, the bus link layer adopts FASTDP-BUS technology to realize data transmission between various modules. Data communication between the main control module and other modules adopts a memory exchange mechanism. The interactive data does not require a one-to-one correspondence of commands, which improves data transmission efficiency and overcomes the cumbersome delay waiting control introduced by the unpreparedness of the transmitted data.

[0053] Furthermore, implementing the FASTDP-BUS link protocol using an FPGA allows the FPGA to be connected via the processor's eMMC bus, while also being compatible with data transmission through both USB and Ethernet interfaces. Moreover, the USB and Ethernet interfaces can be modularly expanded.

[0054] It should be noted that when the first bus module, the second bus module, and the third bus module are all FPGAs, the above scheme is equivalent to using FPGA to build a hardware signal conversion bridge. When the master control module and the slave module communicate, the use of CPU and multiple protocol operation conversions are reduced, thereby improving CPU resource utilization and communication speed.

[0055] In addition, the intelligent transformer area monitoring terminal provided in this embodiment adopts a hardware function configuration design, which distributes the main functions to multiple expansion modules with the main control module as the core, reducing the cost of equipment upgrade and maintenance. As a result, users can expand the functions of the monitoring equipment as needed, improving the adaptability and flexibility of the monitoring equipment in different application backgrounds.

[0056] This disclosure provides an intelligent transformer area monitoring terminal. Since each functional module of the intelligent transformer area monitoring terminal can use a bus module to convert data from different hardware interfaces into bus data that follows the same protocol, different hardware interfaces do not need to occupy additional CPU resources. The bus module can be used to perform protocol conversion on the data of each hardware interface, thereby improving the CPU resource utilization of the intelligent transformer area monitoring terminal.

[0057] In one embodiment of this disclosure, such as Figure 2The diagram shown is a structural schematic of the intelligent area monitoring terminal according to an embodiment of this disclosure. The main control module 11 further includes a first universal serial bus controller. One end of the first universal serial bus controller is connected to the target interface, and the other end of the first universal serial bus controller is connected to the second bus module. The first universal serial bus controller is used to perform universal serial bus data transmission between the processor and the second bus module.

[0058] In one embodiment of this disclosure, the first Universal Serial Bus controller includes a Universal Serial Bus driver, a Universal Serial Bus interface, and a Universal Serial Bus protocol.

[0059] In one embodiment of this disclosure, the target interface is a USB interface, thereby the second bus module converts the USB data obtained through the USB interface into second bus data.

[0060] In this embodiment, by adding a USB controller between the second bus module of the main control module and the processor, the processor can perform USB data transmission with the second bus module through a standard USB driver.

[0061] Furthermore, in one embodiment of this disclosure, such as Figure 2 The diagram shown is a structural schematic of the intelligent transformer area monitoring terminal according to an embodiment of this disclosure. The data collection module 13 further includes a second universal serial bus controller. One end of the second universal serial bus controller is connected to the universal serial bus interface of the power line carrier communication module, and the other end of the second universal serial bus controller is connected to the third bus module. The second universal serial bus controller is used to perform universal serial bus data transmission between the power line carrier communication module and the third bus module.

[0062] In one embodiment of this disclosure, the second universal serial bus controller and the first universal serial bus controller have the same function, but their shape and size may be the same or different.

[0063] In one embodiment of this disclosure, USB data can be obtained through the universal serial bus interface of the power line carrier communication module, thereby the third bus module converts the USB data into third bus data.

[0064] It should be noted that the above embodiment is illustrated using an example where the data collection module only includes a power line carrier communication module. Of course, if the data collection module also includes other functional circuit modules, the USB interfaces of these other functional circuit modules can be connected to one end of the second universal serial bus controller, thereby enabling the management of USB interface data through the second universal serial bus controller.

[0065] In this embodiment, by adding a USB controller between the third bus module and the power line carrier communication module of the data collection module, USB data transmission between the third bus module and the power line carrier communication module can be realized.

[0066] In this embodiment of the present disclosure, the second bus module in the main control module and the third bus module in the data collection module implement data exchange routing logic to complete the transparent transmission of USB application data between the master and slave USB interfaces. In this solution, the USB interface of the processor of the main control module and the USB interface of the slave module can be equivalent to a direct connection. Therefore, the processor of the main control module only needs to access the application data of the power line carrier communication module under the specified standard USB protocol.

[0067] In one embodiment of this disclosure, such as Figure 3 The diagram shown is a structural schematic of an intelligent area monitoring terminal according to an embodiment of this disclosure. The main control module 11 further includes an Ethernet switching chip. One end of the Ethernet switching chip is connected to the target interface, and the other end of the Ethernet switching chip is connected to the second bus module. The Ethernet switching chip is used to perform Ethernet data transmission between the processor and the second bus module.

[0068] In one embodiment of this disclosure, the Ethernet switching chip can be understood as a chip that integrates an Ethernet controller.

[0069] In one embodiment of this disclosure, the target interface is an Ethernet interface, thereby the second bus module converts the Ethernet data obtained through the Ethernet interface into second bus data.

[0070] In this embodiment, by adding an Ethernet switching chip between the second bus module of the main control module and the processor, the processor can perform Ethernet data transmission with the second bus module through a standard Ethernet driver.

[0071] Furthermore, in one embodiment of this disclosure, such as Figure 3 The diagram shown is a structural schematic of the intelligent transformer area monitoring terminal according to an embodiment of this disclosure. The data collection module 13 further includes an Ethernet controller. One end of the Ethernet controller is connected to the Ethernet interface of the power line carrier communication module, and the other end of the Ethernet controller is connected to the third bus module. The Ethernet controller is used to perform Ethernet data transmission between the power line carrier communication module and the third bus module.

[0072] In one embodiment of this disclosure, the Ethernet controller and the Ethernet switching chip have the same function, but their shape and size may be the same or different.

[0073] In one embodiment of this disclosure, Ethernet data can be obtained through the Ethernet interface of the power line carrier communication module, thereby the third bus module converts the Ethernet data into third bus data.

[0074] It should be noted that the above embodiment is illustrated using an example where the data collection module only includes a power line carrier communication module. Of course, if the data collection module also includes other functional circuit modules, the Ethernet interfaces of these other functional circuit modules can be connected to one end of the Ethernet controller, thereby enabling the management of Ethernet interface data through the Ethernet controller.

[0075] In this embodiment, by adding an Ethernet controller between the third bus module and the power line carrier communication module of the data collection module, Ethernet data transmission between the third bus module and the power line carrier communication module can be realized.

[0076] In this embodiment of the present disclosure, the second bus module in the main control module and the third bus module in the data collection module implement data exchange routing logic to complete the transparent transmission of Ehternet application data between the master and slave Ehternet interfaces. In this scheme, the processor of the main control module and the Ehternet interface of the slave module can be equivalent to a direct connection. Therefore, the processor of the main control module only needs to access the application data of the power line carrier communication module under the specified standard Ehternet protocol.

[0077] The third bus module and power line carrier communication module used in the data collection module described in the above embodiments are used to realize the access method of the power line carrier communication module, which can support the access of various interfaces of the power line carrier communication module and the data transmission requirements.

[0078] Furthermore, using a third bus module to control the power line carrier communication module avoids the need for module software design, upgrades, and maintenance, enabling a fully hardware-based circuit design that simplifies and enhances the module's reliability. It allows the main control module to fully implement the power line carrier communication module's ability to collect user electricity data without modifying existing application software, reducing the need for design changes and testing / certification of the main control module.

[0079] In one embodiment of this disclosure, such as Figure 4 The diagram shown is a structural schematic of an intelligent transformer area monitoring terminal according to an embodiment of the present disclosure. The intelligent transformer area monitoring terminal may further include: an expansion module 15;

[0080] The expansion module 15 includes a serial communication module and a fourth bus module. The serial communication module is connected to the fourth bus module. The fourth bus module is used to convert the data obtained through the serial communication module into fourth bus data and transmit the fourth bus data to the target bus connected to the fourth bus module.

[0081] The fourth bus data follows the target protocol.

[0082] In one embodiment of this disclosure, the serial communication module supports a serial communication interface (UART). For example, the serial communication interface includes RS485 and RS232.

[0083] In one embodiment of this disclosure, the fourth bus module can be understood as an FPGA.

[0084] The description of the target protocol can be found in the detailed description in the above embodiments, and will not be repeated here in this disclosure.

[0085] In this embodiment of the present disclosure, since the expansion module includes a serial communication module, it supports modular expansion of the serial communication interface, thereby ensuring compatibility with the transmission of serial communication interface data.

[0086] The software system architecture of the intelligent distribution area monitoring terminal is centered on the main control module. The main control module's basic system includes the necessary operating system and runtime environment. The system deploys various functional extension modules, adapter programs, and advanced programs for data analysis, calculation, and maintenance. Its overall software architecture adopts the common software architecture of ARM-Linux embedded products. The underlying layer is the Linux operating system. In addition to conventional drivers, the driver layer can write dedicated device drivers and configurable expansion board drivers for extension modules. The user space can directly use the device nodes and SDK interfaces generated by the driver layer to operate and use the extension modules. The application software layer calls the user-space interface to operate the extension modules and read / write their data, implementing specific business functions.

[0087] This disclosure allows multiple extension modules to be accessed simultaneously, and in addition to the extension module types provided in the above embodiments, it also allows users to develop their own extension modules that conform to the configurable extension protocol. Therefore, a combination of dedicated drivers and configurable general-purpose drivers is adopted to support all types of extension modules.

[0088] In one possible implementation of this disclosure, for expansion modules of hardware interfaces such as serial ports, I / O interrupts, and GPIO, dedicated drivers can be written to generate corresponding device nodes. The application layer operates the expansion modules through user-space device nodes. Examples include data collection modules and acquisition modules.

[0089] The steps for data communication between the main control module and the expansion module driven by a dedicated device are as follows:

[0090] (1) The application software 1 of the main control module calls device node 1 to read and write data;

[0091] (2) After the data enters the driver layer, the data is first placed in the send / receive buffer;

[0092] (3) A protocol buffer for organizing data placement can be established according to communication protocols and block protocol specifications;

[0093] (4) Write the organized protocol buffer to the corresponding extension module address;

[0094] (5) After the extension module receives the protocol data, it places the protocol buffer in the transmit and receive buffer. Then the extension module can parse the transmit and receive buffer and complete the data interaction.

[0095] In one possible implementation of this disclosure, a unified protocol can be used to interact with the main control module for configurable general-purpose extension modules. This unified protocol includes operation types such as read, write, and notification. If a user uses a customized extension module, it is typically not accessible through the device nodes of the device system. To address this issue, customized business applications access the extension module using a general-purpose board protocol SDK. Specifically, after the terminal powers on, it checks the board connection status and initializes the connected boards. During initialization, it obtains basic information such as the model, status, version, and serial number of the connected boards, as well as a list of supported functions. After initialization, it sends an initialization completion notification to the motherboard processor. The motherboard daemon updates the board status, and the application can then access it through the SDK.

[0096] The above description is merely a preferred embodiment of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features disclosed in this disclosure that have similar functions.
