[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0026] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0027] Firstly, referring to Figure 1 This utility model provides a serial port debugging device, including: an RJ45 network port, a toggle switch and a DB9 female connector;
[0028] The RJ45 network port is used to connect to the device under test and send the device information of the device under test to the DB9 female connector;
[0029] The toggle switch is used to move to the first position so that the RJ45 network port can be electrically connected to the DB9 female connector through a protocol defined by a first standard; and to move to the second position so that the RJ45 network port can be electrically connected to the DB9 female connector through a protocol defined by a second standard, wherein the protocol defined by the first standard and the protocol defined by the second standard belong to the same protocol defined by different standards;
[0030] The DB9 female header is used to send the device information to the host computer.
[0031] Specifically, the RJ45 (Registered Jack 45) network port is a commonly used network interface widely used in Ethernet connections. It consists of an 8-pin connector (usually called a crystal head) and a corresponding 8-pin socket. Each of these pins corresponds to a specific wire color, forming the basis of color-coded wiring arrangements crucial for connector operation. This application connects electrically to the device under test (DUT) via the RJ45 network port. The DUT is the secondary terminal equipment of the distribution network that needs to be measured. Generally, secondary terminal equipment of the distribution network uses different standard definitions for the same protocol. When connecting to secondary terminal equipment with different standard definitions, the pins of the secondary terminal equipment must be matched, meaning the pins of the secondary terminal equipment with different standard definitions have different functions. This application adapts to different standard definitions by switching a toggle switch to different positions according to the secondary terminal equipment with different standard definitions. If the secondary terminal equipment in the distribution network uses the first standard definition protocol, switching the toggle switch to the first position will allow the RJ45 port to electrically connect to the DB9 female connector using the first standard definition protocol. This sends the device information of the secondary terminal equipment to the DB9 female connector, which then directly sends the device information to the host computer for analysis and testing. By switching the toggle switch to different positions, different standard definitions of protocols can be matched, enabling rapid adaptation to different standard definitions of protocols. This results in high work efficiency and eliminates the need for traditional manual wiring, reducing the risk of connection failure due to wiring errors in the secondary terminal equipment.
[0032] In some optional embodiments, the protocol defined by the first standard is configured as RS232 as defined by the first standard, and the protocol defined by the second standard is configured as RS232 as defined by the second standard.
[0033] Specifically, the RS232 pin definitions mainly include RXD, TXD, and GND. The corresponding RJ45 network port definitions for RS232 vary by region. When using an RS232 serial debugging cable (USB-DB9), upon connecting to the DB9 port, observe whether the secondary terminal device connected via RJ45 belongs to the State Grid standard RS232 definition (the first standard definition) or the Southern Power Grid standard RS232 definition (the second standard definition). Switch the toggle switch to the indicated standard of the device under test to enable communication between the host computer and the device under test.
[0034] In some alternative embodiments, the toggle switch includes a chip SS-23H02 and peripheral circuitry of the chip SS-23H02.
[0035] In some optional embodiments, when the toggle switch is to the first position, the first signal output pin of the SS-23H02 chip is electrically connected to the first signal input pin of the RJ45 network port, and the first signal input pin of the SS-23H02 chip is electrically connected to the first signal output pin of the RJ45 network port; when the toggle switch is to the second position, the second signal output pin of the SS-23H02 chip is electrically connected to the second signal input pin of the RJ45 network port, and the second signal input pin of the SS-23H02 chip is electrically connected to the second signal output pin of the RJ45 network port.
[0036] Specifically, refer to Figure 2-3 When the toggle switch is moved to the first position, the first signal output pin (pins 5 and 8) of the SS-23H02 chip is electrically connected to the first signal input pin (pin 3) of the RJ45 network port, and the first signal input pin (4) of the SS-23H02 chip is electrically connected to the first signal output pin (pin 1) of the RJ45 network port, so that the RJ45 network port is electrically connected to the SS-23H02 chip through the protocol defined by the first standard, and the device information sent by the RJ45 network port is sent to the DB9 female connector through the SS-23H02 chip. Similarly, when the toggle switch is moved to the second position, the second signal output pin (pin 7) of the SS-23H02 chip is electrically connected to the second signal input pin (pin 7) of the RJ45 network port, and the second signal input pin (2) of the SS-23H02 chip is electrically connected to the second signal output pin (pin 4) of the RJ45 network port, so that the RJ45 network port is electrically connected to the SS-23H02 chip through the protocol defined by the second standard, and the device information sent by the RJ45 network port is sent to the DB9 female connector through the SS-23H02 chip.
[0037] In some optional embodiments, the signal output pins of the XH terminal and the plug-in terminal are both electrically connected to the third signal input pin of the DB9 female connector, and the signal input pins of the XH terminal and the plug-in terminal are both electrically connected to the third signal output pin of the DB9 female connector.
[0038] In some optional embodiments, the DB9 female connector is also electrically connected to an XH terminal and a plug-in terminal. The XH terminal is electrically connected to the device under test via a protocol defined by a first standard or a protocol defined by a second standard, and the plug-in terminal is electrically connected to the device under test via a protocol defined by a first standard or a protocol defined by a second standard.
[0039] Specifically, refer to Figure 4The signal output pin (pin 1) of the XH terminal (J5) is electrically connected to the third signal input pin (pin 2) of the DB9 female connector, and the signal input pin (pin 2) of the XH terminal (J5) is electrically connected to the third signal output pin (3) of the DB9 female connector; similarly, the signal output pin (pin 2) of the plug-in terminal (J6) is electrically connected to the third signal input pin (pin 2) of the DB9 female connector, and the signal input pin (pin 3) of the plug-in terminal (J6) is electrically connected to the third signal output pin (3) of the DB9 female connector. This application allows for electrical connection to the device under test (DUT) via the XH terminal using either the first or second standard-defined protocol, without using an RJ45 network port. Similarly, the plug-in terminal allows for electrical connection to the DUT using either the first or second standard-defined protocol, enabling the serial port debugging device to adapt to more interface types of DUTs. The specific standard definition is determined based on the specific wiring and is not limited here.
[0040] In some optional embodiments, the serial port debugging device further includes an LCD interface, which is electrically connected to the RJ45 network port and is used to send the device information to the LCD screen.
[0041] In some optional embodiments, the toggle switch is also used to toggle to a third position so that the RJ45 network port is electrically connected to the liquid crystal interface via a protocol defined by a third standard.
[0042] In some optional embodiments, the signal output pin of the liquid crystal interface is electrically connected to the first signal input pin of the RJ45 network port, and the signal input pin of the liquid crystal interface is electrically connected to the first signal output pin of the RJ45 network port.
[0043] Specifically, refer to Figure 2 and 5 When the toggle switch is moved to the third position, the RJ45 network port is electrically connected to the LCD interface through the protocol defined by the third standard (i.e., the LCD standard definition). The LCD interface then sends the device information of the device under test to the LCD screen for display. The signal input pin (pin 3) of the LCD interface is electrically connected to the first signal output pin (1) of the RJ45 network port, and the signal output pin (pin 2) of the LCD interface is electrically connected to the first signal input pin (3) of the RJ45 network port.
[0044] In some optional embodiments, the serial port debugging device of this application is small in size, with a length, width and height of only 80*50*20mm. It not only meets the requirements of everyday tool environments, but can also be easily carried in a pocket for use during business trips. It meets the RS232 serial port definitions of both the State Grid and Southern Power Grid standards. Even when encountering devices without an RJ45 debugging port, it can be connected to the device under test through two external terminals (XH terminal and plug-in terminal). (Both XH terminal and plug-in terminal are silkscreened and correspond one-to-one with the RS232 required for communication). It is basically compatible with all devices with RS232 on the market.
[0045] In some alternative embodiments, the potential time cost of setting up the test environment and correcting incorrect wiring in the field debugging environment is high. This serial port debugging tool can avoid the above risks, and according to calculations, the cost of a single BOM can be controlled within 100 yuan, which greatly improves the adoption rate.
[0046] The implementation of this utility model embodiment has the following beneficial effects: This utility model embodiment provides a serial port debugging device, including: an RJ45 network port, a toggle switch, and a DB9 female connector; the RJ45 network port is used to connect to the device under test (DUT) and send the DUT's device information to the DB9 female connector; the toggle switch is used to toggle to a first position, so that the RJ45 network port is electrically connected to the DB9 female connector through a first standard-defined protocol; and to toggle to a second position, so that the RJ45 network port is electrically connected to the DB9 female connector through a second standard-defined protocol; the DB9 female connector is used to send the device information to a host computer. By selecting the standard-defined protocol that is compatible between the RJ45 network port and the DB9 female connector through the toggle switch, it is possible to communicate with DUTs that have different standard-defined protocols, so that the DB9 female connector can send the DUT's device information to the host computer for testing. It can quickly adapt to different standard-defined protocols, has high working efficiency, and eliminates the need for manual wiring, reducing the risk of wiring errors causing secondary terminal equipment in the power distribution network to malfunction.

[0048] It is evident that the contents of the above-described serial port debugging device embodiments are all applicable to this system embodiment.
