Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Please combine Figure 1 and Figure 2 The utility model discloses a switch suitable for rail transit, aiming to solve the problem that the existing switch cannot meet the needs of multiple terminal devices in rail transit stations.

[0020] The first embodiment of the present invention provides a switch suitable for rail transit, comprising: a chassis body, a front panel 14 configured on the chassis body, a CPC I backplane 13, and a switch body 1;

[0021] The switch body 1 includes a power supply, a PCB board, a controller 12 configured on the PCB board, an optical port module 11 electrically connected to the controller 12, multiple optical ports 14 configured on the front panel 14 are electrically connected to the optical port module 11, and the controller 12 is electrically connected to the communication interface 131 on the CPCI backplane 13;

[0022] The power supply is electrically connected to the power supply terminal of the CPCI backplane 13, the power supply terminal of the controller 12, and the power supply terminal of the optical port module 11;

[0023] The plurality of optical ports 14 are used to connect to terminal devices configured on the rail transit, and the communication interface 131 is used to communicate with a service host.

[0024] It should be noted that the power supply can provide a reliable power supply for the entire switch through the backplane, ensuring that each module can operate stably in the complex environment of rail transit. A controller 12 is configured on the PCB board, which can be but is not limited to the STM32 series of single-chip microcomputers. It serves as the core control unit of the entire switch and is connected to multiple electrical connections on the optical port module 11 and the front panel 14. The multiple optical ports 14 are used to connect various terminal devices in rail transit through optical fibers, such as displays, monitoring equipment or broadcasting systems in the station, to achieve high-speed and reliable transmission of data. It is worth noting that the power supply can power each module through each power circuit (such as a boost circuit or a buck circuit), and each power circuit is controlled by the controller 12. The controller 12 can restart each module by means of on-off circuits and the like.

[0025] Furthermore, in this embodiment, the controller 12 communicates with the service host through the communication interface 131 on the CPCI backplane 13. This interface is responsible for uploading various types of information collected by the terminal device to the service host to realize centralized processing and monitoring of data. It should be understood that the communication interface 131 between the CPCI backplane 13 and the service host can not only realize data interaction with the host, but also support subsequent equipment expansion and upgrade to adapt to the growing needs of future rail transit systems.

[0026] In a possible embodiment of the present invention, the communication interface 131 is an IPMI interface, wherein the IPMI interface can provide an IPMI control channel for the switch body 1 and the service host.

[0027] It should be noted that the communication interface 131 adopts an IPMI interface design, which provides a reliable IPMI control channel between the switch body 1 and the service host. The IPMI interface is a standardized interface for platform management, enabling remote monitoring and management of the switch body 1 through an independent management channel.

[0028] In practical applications, the IPM 1 interface not only enables real-time monitoring of the switch 1's status via the service host, but also supports remote configuration, management, and troubleshooting of the switch. Specifically, the IPM 1 interface monitors key parameters of the switch 1, such as its operating status, temperature, and power supply, through its independent control channel. When an anomaly is detected, it promptly sends an alarm to the service host. Through this control channel, the service host can reboot the switch, remotely update firmware, and collect and analyze system logs.

[0029] In a possible embodiment of the present invention, the present invention further includes: a plurality of first LED lights corresponding to the optical ports 14 arranged on the front panel 14 , wherein the first LED lights are used to indicate the working status of the optical ports 14 .

[0030] It should be noted that each optical port 14 corresponds to a first LED light, which is used to intuitively display the working status of the optical port 14. Specifically, when the switch body 1 is working normally, each LED light will change in real time according to the connection status and data transmission status of the optical port 14. When a certain optical port 14 is in working condition and successfully establishes a connection with the terminal device, the corresponding first LED light will continue to light up, indicating that the optical port 14 is working normally. If the optical port 14 is not connected or the connection fails, the corresponding LED light will remain off, intuitively showing that the current port is not in use. In addition, during the data transmission process, the LED light can also indicate the data transmission rate or whether there is a transmission anomaly through different flashing frequencies or colors.

[0031] In a possible embodiment of the present invention, the present invention further includes: an RJ45 interface configured on the front panel 14, wherein the RJ45 interface is electrically connected to the controller 12 through the optical module.

[0032] It should be noted that when the switch needs to establish a physical connection with an external network device, the RJ45 interface realizes communication and data transmission with the controller 12 through an optical module. Specifically, the RJ45 interface can be used to connect the maintenance personnel's computer or other debugging equipment, access the configuration interface inside the switch through the controller 12, or perform real-time data monitoring and management.

[0033] In a possible embodiment of the present invention, the CPC I backplane 13 is extended with a USB interface, an Ethernet interface, and a power interface, wherein the power interface is electrically connected to the power supply, the Ethernet interface is electrically connected to the optical port module, and the USB interface is electrically connected to the controller.

[0034] It should be noted that the Ethernet interface is responsible for realizing data transmission and network connection functions. Through the Ethernet interface, the switch can establish a high-speed data connection with other network devices in the rail transit system.

[0035] The expansion of the USB interface provides the device with more peripheral connection options. Users can connect input devices, debugging tools or other external devices through the USB interface to achieve more convenient system debugging. At the same time, the USB interface can also be used for system firmware upgrades or data import.

[0036] The power supply interface provides redundant power supply for the entire system, ensuring that each module can operate stably in complex environments.

[0037] In a possible embodiment of the present invention, the second LED light is configured on the front panel 14, wherein the second LED light is electrically connected to the output end of the controller 12, and the second LED light is used to indicate the working status of the IPMI interface.

[0038] It should be noted that when the IPMI interface is working normally, the second LED light will continue to light up, indicating that the communication channel between the interface and the business host is in normal operation. The second LED light will flash or go out, prompting the operation and maintenance personnel to conduct timely inspection or maintenance.

[0039] A switch suitable for rail transit is proposed based on the present invention. It configures a controller 12 and an optical port module 11 inside a chassis body for electrical connection. Multiple optical ports 14 configured on a front panel 14 can communicate with the controller 12 through the optical port module 11. A CPC I backplane 13 and the controller 12 are configured electrically, and communication is performed with a service host through a communication interface 131 set on the CPC I backplane 13. This enables the service host to perform stable real-time communication with diversified terminals, thereby solving the problem that existing switches cannot meet the needs of diversified terminal devices in rail transit stations.

[0040] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
