[0022] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0023] The present invention provides a portable upgrade device for a power grid FTU terminal. Figure 1 , including a control module and a storage module 2; the control module includes a TTL serial port 11, and the control module is connected to the FTU terminal through the TTL serial port 11 to realize data exchange; the storage module 2 is connected to the control module and is used to store an upgrade program for upgrading the FTU terminal.

[0024] In this embodiment, a TTL (Transistor-Transistor Logic) serial port is used as an upgrade interface to achieve stable data exchange through wired transmission.

[0025] The TTL serial port 11 provides a basic communication method. The control module supports multiple upgrade protocols and can process data transmission according to different protocol requirements.

[0026] In this embodiment, the control module includes a TTL serial port 11, which is connected to the FTU terminal for data exchange. The storage module 2 is used to store the upgrade program of the FTU terminal. When the FTU terminal needs to be upgraded, the portable upgrade device can transmit the upgrade program in the storage module 2 to the FTU terminal through the TTL serial port 11, thereby completing the upgrade process. It can be understood that the utility model does not limit the specific upgrade program, but only provides a carrier that can complete the program upgrade. Those skilled in the art can load a suitable upgrade program into the storage module of the present application according to actual needs.

[0027] This portable upgrade device has the following advantages:

[0028] Portability: Due to its small size, it is easy for staff to carry it to the site to upgrade the FTU terminal.

[0029] Efficiency: Data exchange is achieved through TTL serial port 11, ensuring the stability and speed of data transmission.

[0030] Ease of use: The device is simple in design and easy to operate, allowing staff to quickly upgrade the FTU terminal.

[0031] Security: The upgrade program in storage module 2 has been strictly tested to ensure the safety and stability of the FTU terminal upgrade process.

[0032] Therefore, the portable upgrading device provided by the utility model provides an efficient and convenient solution for the maintenance and upgrading of the FTU terminal of the power grid, which helps to improve the operating efficiency and stability of the power grid.

[0033] Furthermore, the control module has a built-in upgrade protocol, and the upgrade protocol includes a general protocol.

[0034] The general protocols include the grid 101, grid 104 file transfer protocol and the ymodem protocol.

[0035] Specifically, the Grid 101 / 104 File Transfer Protocol are two commonly used protocols in power system communications, based on the IEC 60870-5-101 and IEC 60870-5-104 international standards. They are mainly used for monitoring and control data transmission in power systems. The 101 protocol is usually used for point-to-point communication, while the 104 protocol is used for network communication. Both protocols provide guarantees for data integrity, reliability and security, and are suitable for data transmission and remote control of power grid FTU terminals.

[0036] The Ymodem protocol is a file transfer protocol that is commonly used to transfer data over serial communication lines. The Ymodem protocol provides error detection and verification functions to ensure the integrity of the file during transmission. It is more efficient than the traditional Xmodem protocol because it can transfer multiple data blocks at a time instead of a single data block.

[0037] Accordingly, the control module has multiple built-in upgrade protocols, including the grid 101 / 104 file transfer protocol and the ymodem protocol, to meet different upgrade requirements.

[0038] Furthermore, the user can also set a custom upgrade protocol according to the needs. In the custom upgrade protocol, the custom content includes: at least one of the communication format, communication command, security mechanism, upgrade process or log record.

[0039] Correspondingly, the control module can also be compatible with custom upgrade protocols to meet different upgrade requirements.

[0040] Furthermore, the control module includes a control chip (not shown in the figure), which is used to control the progress of the upgrade. The control chip adopts an STM32F103C8T6 control chip based on the ARM Cortex-M3 core.

[0041] Furthermore, the device also includes a display component 12, and the display component 12 is used to display the operation interface and upgrade progress to make the operation more intuitive.

[0042] The display component 12 is connected to the control chip via a GPIO pin or a first interface, and the first interface includes SPI or I2C.

[0043] Furthermore, the display component 12 includes a display screen, a touch screen or a projection display.

[0044] Preferably, the display component 12 is an LCD display screen.

[0045] In order to extend the working time of the equipment, low-power technology solutions are adopted, such as selecting a small-size LCD display and lowering the operating main frequency to reduce energy consumption.

[0046] Furthermore, the device also includes a housing 15 , the control module is arranged inside the housing 15 , and the housing 15 also includes a first window for embedding the display component 12 .

[0047] Furthermore, the device also includes an operating component 13 disposed on the housing 15, and the operating component 13 is used to implement function switching and selection.

[0048] The operating component 13 includes a button, a knob or a touch pad.

[0049] The operating component is connected to the control chip via a GPIO pin.

[0050] In this embodiment, in order to simplify the operation and improve the efficiency, the portable upgrade device realizes page switching and starts or terminates the upgrade function through one button, which takes into account the convenience of the on-site staff, avoids complicated operation procedures, and also reduces the manufacturing cost of the device.

[0051] Specifically, in a specific example, this button can be a multi-function button that distinguishes different operation instructions through different pressing methods (such as short press, long press). For example, a short press is used to switch between menus or pages, while a long press may be used to confirm a selection or start an upgrade process. This allows users to quickly operate without relying on a complex interface or multiple buttons.

[0052] It should be noted that, in this embodiment, the STM32F103C8T6 control chip supports the implementation of this function, and there is no need to separately set the operation function of the above multi-function button.

[0053] In another specific example, the display component 12 is a touch screen, and the operation interface and upgrade progress can be displayed through the touch screen, and the operation can be performed through the touch screen to switch pages and select functions. Specifically, when the display component 12 is a touch screen, the touch screen integrates a touch sensor, and the touch sensor can directly detect the user's touch operation and convert these touch operations into electrical signals to send to the control chip.

[0054] It is understandable that the present invention does not limit the specific control method, but only provides a portable carrier capable of completing program upgrades. Those skilled in the art can integrate appropriate display components and operating components into the portable device of the present application according to actual needs.

[0055] Specifically, the operation interface displayed on the touch screen may include the following:

[0056] Menu bar: used to select different functions, such as program upgrade, system settings, status view, etc.

[0057] Progress bar: Displays the current upgrade progress during the upgrade process, allowing users to understand the upgrade status.

[0058] Buttons or icons: Used to confirm a selection, cancel an action, or execute a specific command.

[0059] Prompt information: Provides operation instructions, error messages or other relevant information.

[0060] Users can interact with the touch screen in the following ways:

[0061] Click: Select a menu item, button, or icon.

[0062] Swipe: Switch between pages or options.

[0063] Long press: May be used to launch a specific function or access a hidden menu.

[0064] The use of touch screens reduces the number of physical buttons, making the user interface neater and providing more interactive possibilities. In addition, the graphical interface of a touch screen is usually more intuitive than a simple text interface, which helps improve operating efficiency and reduce the possibility of misoperation.

[0065] In this embodiment, the built-in multiple protocols can be selected through the operation module, and then the program to be upgraded can be selected to start or terminate the upgrade. The upgrade process information can be intuitively understood through the display component 12, including upgrade status, upgrade progress, upgrade version and other information.

[0066] In addition, after the upgrade is successful, the new version number can be queried and displayed through the display component 12 and the operation component 13 to confirm whether the upgrade is successful.

[0067] Furthermore, the device also includes a power supply 14, which is connected to the control module to supply power to the Confucius module 1.

[0068] In this embodiment, the control module is also equipped with a USB interface for charging the power source 14 .

[0069] Wherein, the control module and the storage module 2 are connected.

[0070] In this embodiment, the control module is equipped with a large-capacity external Flash chip, and the Flash chip is used to store the upgrade program. The upgrade program is downloaded to the Flash by the administrator, which ensures the security of the program.

[0071] In a specific example, an engineer carries the portable upgrade device provided by the utility model for on-site upgrade, uses a TTL serial line to access the FTU terminal device, selects the upgraded protocol and the corresponding upgraded program, operates to confirm the upgrade, and waits for the upgrade to be completed. During the upgrade process, the upgrade progress flow will be displayed, and the upgrade status will be intuitively fed back. After the upgrade is successful, the corresponding version number can be queried to ensure the correctness of the upgrade.

[0072] In summary, a portable upgrade device for a power grid FTU terminal is provided, including a control module and a storage module, taking into account the actual needs of field work, and providing an efficient, reliable and easy-to-use solution by integrating a TTL serial port, a touch screen operation interface and a large-capacity storage. It not only improves the maintenance and upgrade efficiency of the power grid FTU terminal, but also reduces the complexity and cost of field work.

[0073] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
