Description

Technical Field

[0001] The utility model relates to the technical field of distribution networks, in particular to a field upgrade device for distribution automation terminals (FTU, DTU, intelligent distribution transformer terminals, and intelligent fusion terminals for distribution transformer areas). Background Art

[0002] Since 2019, the State Grid Corporation of China has used a new type of device, namely, an intelligent fusion terminal for distribution transformer areas, to realize the monitoring of electricity consumption information and data collection in low-voltage distribution transformer areas. The software upgrade of the intelligent fusion terminal for distribution transformer areas is usually remotely achieved through Ethernet or 4G public network communication. In actual use, first, the communication network restricts the upgrade of the intelligent fusion terminal for distribution transformer areas. In places without a network or with poor network signals, the upgrade of the intelligent fusion terminal for distribution transformer areas is affected, directly resulting in the abnormal operation of the intelligent fusion terminal for distribution transformer areas. Second, there are many manufacturers of the intelligent fusion terminal for distribution transformer areas, and the upgraded software and operation processes are different. Incorrect installation of the software will also cause the intelligent fusion terminal for distribution transformer areas to malfunction. Third, once events such as power failure or faults occur in the distribution transformer area, most of them will cause communication interruption, thus cutting off the upgrade channel for the intelligent fusion terminal for distribution transformer areas, and some faults that can be solved through software upgrade cannot be handled.

[0003] Currently, for the intelligent fusion terminal for distribution transformer areas that shows abnormal operation or faults, it is usually required that the manufacturer dispatches maintenance personnel to the site to handle the problem. A local fault handling device, such as a portable terminal (including a laptop computer, PDA, and iPad), is used to connect to the intelligent fusion terminal for distribution transformer areas, and the local upgrade of the intelligent fusion terminal for distribution transformer areas is remotely achieved through Ethernet or 4G public network communication. However, when a general portable terminal does not have the hardware and control software resources required for the maintenance of the intelligent fusion terminal for distribution transformer areas, ordinary personnel cannot operate and manage the intelligent fusion terminal for distribution transformer areas. Even if the portable terminal has the hardware and control software resources required for the maintenance of the intelligent fusion terminal for distribution transformer areas, the operator must have relevant professional knowledge to achieve the maintenance and upgrade of the intelligent fusion terminal for distribution transformer areas, further increasing the professional requirements for the operator. After all, the number of maintenance personnel of the manufacturer is limited, and many faults cannot be handled in a timely manner, severely restricting the application of the intelligent fusion terminal for distribution transformer areas, reducing the working efficiency of the intelligent fusion terminal for distribution transformer areas, and increasing the operation cost of the intelligent fusion terminal for distribution transformer areas.

Those skilled in the art should understand that the present utility model can also be implemented without these specific details. In some other instances, well-known methods, means, elements and circuits are not described in detail so as to highlight the gist of the present utility model.

[0031] Embodiment 1

[0032] The present utility model discloses an on-site upgrade device for intelligent upgrade of distribution automation terminals (FTU, DTU, intelligent distribution transformer terminal, district intelligent fusion terminal). In the following description, the present utility model takes the intelligent upgrade of the district intelligent fusion terminal by the on-site upgrade device as an example for illustration. It can be understood that the upgrade object executed by the present utility model is not limited to the district intelligent fusion terminal, but can also be applied to other distribution automation terminals adapted to the on-site upgrade device, and the present utility model makes no limitation thereto.

[0033] Figure 1 It is the overall schematic diagram of the circuit module of the on-site upgrade device of the present utility model.

[0034] As Figure 1As shown in the figure, the on-site upgrade device of the present utility model includes: a main control unit, a network and serial port unit, a debugging interface unit, a keyboard and display interface unit, and a lithium battery power management unit. The main control unit is electrically connected to the network and serial port unit, the debugging interface unit, the keyboard and display interface unit, and the lithium battery power management unit respectively.

[0035] The network and serial port unit is electrically connected to the intelligent integrated terminal of the substation area through the Ethernet transceiver chip IP101GA to achieve 100M network communication; and is electrically connected to the intelligent integrated terminal of the substation area through the serial port conversion chip SP3232 to achieve serial port communication.

[0036] Figure 2 It is a schematic circuit diagram of the network and serial port unit of the present utility model.

[0037] As Figure 2 shown, the network and serial port unit includes an Ethernet transceiver chip IP101GA, a network port transformer chip H1102NL, a serial port conversion chip SP3232, and an RJ45 connector socket integrated on the circuit board. The Ethernet transceiver chip IP101GA realizes a 100M network interface and has the functions of line sequence and rate adaptation. The main control unit (ESP32 module) of the on-site upgrade device is electrically connected to the RJ45 connector socket through the Ethernet transceiver chip IP101GA and the network port transformer chip H1102NL. The RJ45 connector socket is connected to the network port of the intelligent integrated terminal of the substation area through a dedicated connecting line described later; the main control unit (ESP32 module) of the on-site upgrade device is also connected to the RJ45 connector socket through the serial port conversion chip SP3232. The serial port conversion chip SP3232 provides a RS232 interface. The RJ45 connector socket is connected to the serial port of the intelligent integrated terminal of the substation area through a dedicated connecting line described later.

[0038] The RJ45 connector socket of the present utility model is a connector socket that multiplexes the network port and the serial port. In one example, the four wires 1, 2, 3, and 6 of the used RJ45 connector socket are used as standard network communication lines, and the four wires 4, 5, 7, and 8 are used as serial port communication lines. In one implementation, the wires 7 and 8 can also be used as the ground wires of the serial port. That is, the present utility model adopts the method of customizing the connecting line to multiplex one RJ45 connector socket into two interfaces of the network port and the serial port. The on-site upgrade device is connected to the network port and the serial port of the intelligent integrated terminal of the substation area through the RJ45 connector socket via a dedicated data line.

[0039] The debugging interface unit mainly consists of a standard TYPE-C interface and an FT232RL chip to form a debugging interface. The TYPE-C interface can selectively switch to connect to an external power supply or an external controller (a host computer or a server). When the TYPE-C interface switches to connect to the external power supply, the external power supply realizes the external power supply of the on-site upgrade device through the standard TYPE-C interface.

[0040] The keyboard and display interface unit uses the I2C bus to connect the interface chip 9534 to the OLED display screen. The OLED display screen is used to display information such as the current working status of the on-site upgrade device; the keyboard and display interface unit also includes: a plurality of key modules S1, S2, S3, which correspond one by one to a plurality of different versions of upgrade programs and are used to indicate and identify the upgrade program that matches the type of the identified district intelligent fusion terminal; and a confirmation key module, which is used to determine the input of the correct version upgrade program when the district intelligent fusion terminal is upgraded.

[0041] The lithium battery power management unit realizes the charge and discharge management of the built-in lithium battery of the on-site upgrade device. In one example, the on-site upgrade device is built with a 1200 mAh lithium battery, and the lithium battery power management unit uses the TP5400 chip to realize the charge and discharge management of the lithium battery.

[0042] The main control unit is the core of the on-site upgrade device, which is implemented using, for example, an ESP32 module. The main control unit executes:

[0043] (1) Network management: Implement TFTP service, FTP service, and the 698 application that matches the district intelligent fusion terminal. The 698 application refers to an application program that complies with the State Grid's "DL / T 698.45-2017 Electric Energy Information Collection and Management System Part 4-5: Object-Oriented Interoperable Data Exchange Protocol". This protocol is mainly for communication with on-site devices to realize the collection of relevant data such as electricity consumption.

[0047] (5) Display management of the display screen: Realize the built-in Chinese character library and full Chinese prompt for interactive information.

[0048] (6) Monitoring of battery power and charge and discharge management: Real-time collection of the battery power and charge and discharge status to prevent upgrade failure caused by abnormal power-off or insufficient power.

[0049] (7) Implementing a TF card interface: Storing and accessing upgrade files and other related data through the TF card.

[0050] Figure 3 This is a schematic diagram of the bottom interface of the on-site upgrade device of the present utility model.

[0051] As Figure 3 shown, the on-site upgrade device is provided with a standard TYPE-C interface 110, a power switch 120, and a multiplexed connection line interface 130 at the base of the housing. The TYPE-C interface 110 is a multi-functional interface module. When the on-site upgrade device executes the upgrade mode for the intelligent fusion terminal in the substation area, the TYPE-C interface 110 is connected to an external power supply (for example, mains power or a secondary battery), and the external power supply supplies power to the on-site upgrade device via the TYPE-C interface module 110, that is, the TYPE-C interface 110 is only used as a power supply interface. When the on-site upgrade device executes the local update mode, the TYPE-C interface 110 is connected to an external controller (a main computer or a server) using a data cable, and the TYPE-C is used as a local debugging interface for the firmware program upgrade of the on-site upgrade device itself, and the firmware upgrade of the on-site upgrade device is realized through the local or cloud program of the computer or the server. At this time, the on-site upgrade device operates using the built-in power supply.

[0052] The multiplexed connection line interface 130 corresponds to an RJ45 connector socket, and the on-site upgrade device simultaneously connects the network port and the serial port of the intelligent fusion terminal in the substation area through the multiplexed connection line interface 130 via a dedicated data cable.

[0053] The power switch 120 is used to connect or disconnect the power supply to the on-site upgrade device.

[0054] Preferably, the standard TYPE-C interface module 110 is implemented using an FT232 chip.

[0055] Figure 4 This is the dedicated connection line 200 of the on-site upgrade device of the present utility model. One end of the dedicated connection line 200 is provided with an RJ45 plug 201 (debugging serial port), and the dedicated connection line 200 forms two branches in the middle on the side opposite to the RJ45 plug 201. The top of the first branch is provided with a 100M network port plug 202, and the top of the second branch is provided with a 3-wire 232 serial port plug 203.

[0056] Figure 5 This is a schematic diagram of the on-site upgrade device 100 of the present utility model connected to the intelligent fusion terminal 300 in the substation area through the dedicated connection line 200. AsFigure 5 As described above, the intelligent integrated terminal 300 in the substation area has a debugging serial port and two network ports, and can achieve on-site communication and debugging.

[0057] The RJ45 plug 201 at one end of the dedicated connection line 200 is connected to the multiplexed connection line interface 130 of the on-site upgrade device. The gigabit network port plug 202 of the first branch at the other end of the dedicated connection line 200 is connected to the network interface socket FE1 of the intelligent integrated terminal in the substation area. The 3-wire 232 serial port plug 203 of the second branch at the other end of the dedicated connection line is connected to the debugging interface of the intelligent integrated terminal in the substation area.

[0058] When the on-site upgrade device needs to perform network communication with the intelligent integrated terminal in the substation area, communication can be carried out through the network communication link composed of the multiplexed connection line interface 130 of the on-site upgrade device 100, the gigabit network port plug 202 of the dedicated connection line 200, and the network interface socket FE1 of the intelligent integrated terminal in the substation area. When the on-site upgrade device needs to perform serial communication with the intelligent integrated terminal in the substation area, communication can be carried out through the serial communication link composed of the multiplexed connection line interface 130 of the on-site upgrade device 100, the 232 serial port plug 203 of the dedicated connection line 200, and the serial port of the intelligent integrated terminal in the substation area.

[0059] In a specific application scenario, the on-site upgrade device 100 detects the status of the intelligent integrated terminal 300 in the substation area. For example, it detects the network configuration parameters of the intelligent integrated terminal 300 in the substation area, whether the application software and drivers are installed, and whether the versions of the application software and drivers are correct, etc.

[0060] If the on-site upgrade device 100 detects that the network configuration parameters of the intelligent integrated terminal 300 in the substation area are incorrect and / or the corresponding application software and drivers are not installed correctly, in this case, the network port of the intelligent integrated terminal 300 in the substation area cannot work properly. In this situation, the on-site upgrade device 100 can only complete the setting of the corresponding network configuration parameters of the intelligent integrated terminal 300 in the substation area and / or the installation of the drivers and software through the debugging serial port of the intelligent integrated terminal 300 in the substation area, and then the network port of the intelligent integrated terminal 300 in the substation area can work properly.

[0061] In the present utility model, the on-site upgrade device 100 uses the dedicated connection line 200 to communicate with the serial port and / or network port of the intelligent integrated terminal 300 in the substation area to achieve operations such as debugging and software upgrade of the intelligent integrated terminal 300 in the substation area.

[0062] In a specific example, when in accordance with Figure 5After the on-site upgrade device 100 is connected to the distribution transformer area intelligent fusion terminal 300 through the dedicated connection line 200 as shown, first, the on-site upgrade device 100 checks the relevant information of the distribution transformer area intelligent fusion terminal 300 through serial communication with the distribution transformer area intelligent fusion terminal 300, including the network configuration parameters of the distribution transformer area intelligent fusion terminal 300, and the installation status of application software and drivers. If the network port configuration parameters of the distribution transformer area intelligent fusion terminal 300 are incorrect or the corresponding application software and drivers are not correctly installed, the on-site upgrade device 100 reconfigures the network configuration parameters of the distribution transformer area intelligent fusion terminal 300 and / or reinstalls the application software and drivers through serial communication with the distribution transformer area intelligent fusion terminal 300.

[0063] When the on-site upgrade device 100 confirms through serial communication with the distribution transformer area intelligent fusion terminal 300 that the network configuration parameters of the distribution transformer area intelligent fusion terminal 300 are correct and the corresponding application software and drivers are correctly installed, the network port of the distribution transformer area intelligent fusion terminal 300 is in a normal communication state, and a notification message indicating that the network port of the distribution transformer area intelligent fusion terminal 300 is in a normal communication state can be sent through the display screen or buzzer of the on-site upgrade device 100.

[0064] When the network port of the distribution transformer area intelligent fusion terminal 300 is in a normal communication state, connect the RJ45 plug 200 at one end of the dedicated connection line 200 to the connection line interface 130 of the on-site upgrade device 100, and connect the gigabit network port plug 201 of the first branch at the other end of the dedicated connection line 200 to the network interface socket FE1 of the distribution transformer area intelligent fusion terminal 300. The on-site upgrade device 100 transmits upgrade files, etc. through the network interface socket FE1 of the distribution transformer area intelligent fusion terminal 300 to achieve on-site upgrade of the distribution transformer area intelligent fusion terminal 300.

[0065] In the present utility model, the on-site upgrade device 100 uses the dedicated connection line 200 to achieve serial and / or network port communication with the distribution transformer area intelligent fusion terminal 300. When the on-site upgrade device 100 confirms through serial communication with the distribution transformer area intelligent fusion terminal 200 that the network configuration parameters of the distribution transformer area intelligent fusion terminal 300 are correct and the corresponding application software and drivers are correctly installed, on-site upgrade of the distribution transformer area intelligent fusion terminal 300 is achieved through the network port of the distribution transformer area intelligent fusion terminal 300, reducing the number of communication cables and lowering the cost of on-site upgrade and maintenance of the distribution transformer area intelligent fusion terminal. The on-site upgrade device adopts an embedded platform, replacing the laptop computer, so that even ordinary staff can complete the maintenance and upgrade work of the distribution transformer area intelligent fusion terminal without a laptop computer, which is easy to apply on a large scale while reducing costs.
