[0030] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application is further described in detail with reference to the following embodiments.

[0031] In the description of the present application, it should be understood that the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, the term "connected" should be understood in a broad sense, which can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] Reference Figure 1 The trackside signal system (CBCT, Communication Based Train Control System) of this embodiment includes multiple trackside element control devices 1, an interlocking computer 2, a second switch 3 and a router 4.

[0033] The above-mentioned trackside element control device 1 is provided with a signal processing component, which includes a trackside element control computer 11, a first switch 12 and a 5G transmission access unit 13. The trackside element control computer 11 (ECC, Element Control Computer) is used for signal connection with a trackside element, which is configured to control the trackside element based on the indication signal of the external interlocking computer 2, and collect the status signal of the trackside element and feed it back to the interlocking computer 2. The first switch 12 is wired to the trackside element control computer 11, and is configured to forward the data from the interlocking computer 2 to the trackside element control computer 11, and forward the data from the trackside element control computer 11 to the interlocking computer 2. The 5G transmission access unit 13 is wired to the first switch 12 and to the 5G dedicated network, and converts the data from the first switch 12 into 5G data format and transmits it to the 5G dedicated network, and converts the data from the interlocking computer 2 received through the 5G dedicated network into Ethernet data format and transmits it to the first switch 12.

[0034] The interlocking computer 2 is configured to send control signals for the trackside elements to the multiple trackside element control devices 1, and receive status signals of the trackside elements fed back from the multiple trackside element control devices 1. For example, each trackside element control device 1 has a fixed IP address, and the interlocking computer 2 can transmit data with different trackside element control devices 1 according to different IP addresses. The trackside element can be a switch 102 or a signal 101.

[0035] The second switch 3 is wired to the interlocking computer 2 and is configured to forward data from the interlocking computer 2 to the trackside element control computer 11, and to forward data from the trackside element control computer 11 to the interlocking computer 2. The router 4 is wired to the second switch 3 to connect the interlocking computer 2 to the 5G dedicated network.

[0036] Thus, in the trackside element control device 1 and the trackside signal system of the above-mentioned embodiment, the trackside element control device 1 enables the trackside element control computer 11, the first switch 12 and a 5G transmission access unit 13 to be centrally placed on the trackside, while the interlocking computer 2, the second switch 3 and the router 4 can be placed in the equipment room, and the interlocking computer 2 and the trackside element control device 1 communicate through the 5G dedicated network. The trackside signal system uses 5G communication, which saves a lot of costs compared to the previous cable communication, improves installation efficiency, and makes the communication distance range of the trackside signal system not limited by cables.

[0037] Reference Figure 2 In a preferred embodiment, the 5G transmission access unit 13 includes an embedded mainboard, and the embedded mainboard integrates a processing controller 131, a memory 132, a communication module 133 and a communication controller 134. For example, the embedded mainboard may be an ARM architecture, and the memory 132 may be an eMMC.

[0038] The processing controller 131 is configured with a routing operating system. The memory 132 stores a configuration file for the processing controller 131 to read. The configuration file includes the IP address of the 5G transmission access unit 13 itself, the IP address of the bound router 4, and the frequency setting is also written in the configuration file to bind the information with the base station, and the initial communication tunnel can be selected, such as IPsec, L2TP, GRE. Further, the processing controller 131 is also connected to a configuration interface 139. For example, the configuration interface 139 can be a DB9 pin interface, and the configuration file can be modified and debugged through the configuration interface 139.

[0039] The communication module 133 is connected to an antenna to access the 5G mobile communication network, and is connected to the processing controller 131 for communication, and also performs conversion between the 5G data format and the Ethernet data format. The communication controller 134 is connected to the processing controller 131 for communication, and performs on-off control of an Ethernet interface 135, which is only for local device connection.

[0040] In this way, the 5G transmission access unit 13 can receive wireless signals from the 5G base station through the 5G communication module 133 and the antenna, and convert the wireless signals into wired signals and forward them to the trackside element control computer 11. At the same time, the 5G transmission access unit 13 also converts the information of the trackside element control computer 11 into 5G signals and transmits them to the 5G base station, and then forwards them to the interlocking computer 2. In this way, the 5G transmission access unit 13 realizes wireless communication between the interlocking computer 2 and the trackside element control computer 11. In addition, the communication module 133 supports the Internet of Things dedicated network card to ensure the communication quality; and supports the frequency point locking function to bind the 5G transmission access unit 13 with the 5G base station cell to avoid the randomness of switching, so as to have higher reliability and security.

[0041] Combination Figure 1 and Figure 2 The Ethernet interface 135 is connected to the trackside element control computer 11 through the first data security module 14. For example, the Ethernet interface 135 is an M12 8-pin X-type interface. In this way, the Ethernet interface 135 adopts an M12 circular locking interface, which is easy to install, has high stability, and has no risk of falling off in a vibration environment.

[0042] Continue to refer to Figure 2 In a preferred embodiment, the 5G transmission access unit 13 also includes an inverter module 136, a step-down module 137 and a power supply interface 138. Among them, the inverter module 136 is configured to convert the 220V AC voltage into the standard DC voltage of the mainboard; the step-down module 137 is configured to reduce the 110V DC voltage to the standard DC voltage of the mainboard, and the power supply interface 138 is an M12 4-core A-type interface, and it is connected to the inverter module 136 and the power input end of the inverter module 136. In this way, 110VDC / 220VAC dual-mode power supply can be adopted without power conversion, which meets the power supply standard of the rail transit industry. In addition, the power supply interface 138 adopts an M12 circular locking interface, which is easy to install, has high stability, and has no risk of falling off in a vibration environment.

[0043] Reference Figure 1In a preferred embodiment, the first data security module 14 of the trackside element control device 1 is wired between the 5G transmission access unit 13 and the first switch 12, and is used to decrypt the data received by the 5G transmission access unit 13 from the interlocking computer 2 and transmit it to the first switch 12, and to encrypt the data from the first switch 12 and transmit it to the interlocking computer 2 through the 5G transmission access unit 13.

[0044] Correspondingly, in the trackside signal system, a second data security module 5 can also be provided in the equipment room. The second data security module 5 is wired between the second switch 3 and the router 4 and is used to encrypt the control signal from the interlocking computer 2 and transmit it to the router 4, and to decrypt the data from the trackside element control device 1 received by the router 4 through the 5G dedicated network and transmit it to the interlocking computer 2.

[0045] In this way, the use of the first data security module 14 and the second data security module 5 can further improve the security of the communication between the interlocking computer 2 and the trackside element control device 1 and prevent data from being tampered with.

[0046] In a preferred embodiment, the trackside element control computer 11, the first switch 12, the 5G transmission access unit 13 and the first data security module 14 can be set in a trackside equipment box so as to be integrated into one device for easy installation and use.

[0047] In addition, in the trackside element control device 1, two hot redundant signal processing components can be configured, the two signal processing components have different IP addresses and are connected to the same trackside element. In this way, dual channels are used to ensure the stability and reliability of the functions of the trackside element control device 1.

[0048] In the trackside signal system, generally, another set of interlocking computers 2, a second switch 3, a second data security module 5 and a router 4 in hot redundant operation may also be included. In this way, dual paths are used to ensure the stability and reliability of the functions of the set of interlocking computers 2. Thus, by using two hot redundant communication links for the trackside element control device 1 and the interlocking computer 2 in the trackside signal system, the stability and reliability of the trackside signal system can be improved as a whole.

[0049] In a preferred embodiment, a dedicated signal tunnel can be established between the router 4 and the 5G transmission access unit 13 in the trackside element control device 1. In this way, it can be ensured that the communication between the interlocking computer 2 and the trackside element control device 1 is not affected by other data transmission. When there is no data transmission between the interlocking computer 2 and the trackside element control device 1, the signal tunnel is still retained.

[0050] In the trackside signal system (CBCT, Communication Based Train Control System), the interlocking computer 2 is also communicatively connected to at least one regional controller 6, and feeds back the working status of the trackside elements on the route to the regional controller 6, and the interlocking computer 2 opens the route according to the calculation results of the regional controller 6.

[0051] The present application relates to the field of rail communication technology, in particular to a 5G transmission access unit 13, a trackside element control device and a trackside signal system. The 5G transmission access unit 13 includes an embedded mainboard, and the embedded mainboard integrates a processing controller 131, a memory 132, a communication module 133 and a communication controller 134. In this way, the 5G transmission access unit 13 realizes wireless communication between the interlocking computer 2 and the trackside element control computer 11. In addition, the communication module 133 supports the Internet of Things dedicated network card to ensure the communication quality; and supports the frequency point locking function to bind the 5G transmission access unit 13 with the 5G base station cell to avoid the randomness of switching, so as to have higher reliability and security.
