[0042] Embodiment 1

[0043] Embodiment 1 of the present invention provides a train control center testing device, such as Figure 1 As shown, the train control center test device is used to test the train control center 4. When performing a functional test on the train control center 4, it is necessary to turn off and on the power supply, disconnect and connect the CAN line, disconnect and connect the network, etc. The train control center test device includes a switch module 1, a switch 2 and a control module 3.

[0044] The switch module 1 includes a power supply contact 11 and a CAN line contact 12 . The power supply contact 11 is electrically connected to the power supply terminal of the train control center 4 , and the CAN line contact 12 is electrically connected to the CAN line terminal of the train control center 4 .

[0045] Among them, the switch module 1 is an electronic component that controls the switch state of the circuit, which can control the opening and closing of the circuit. The disconnection and connection of the power contact 11 of the switch module 1 will affect the disconnection and connection between the power supply terminal of the train control center 4 and the power supply. Specifically, the power supply contact 11 of the switch module 1 is connected in series between the power supply terminal of the train control center 4 and the power supply, so that when the power supply contact 11 of the switch module 1 is connected, the power supply terminal of the train control center 4 is connected to the power supply, and when the power supply contact 11 of the switch module 1 is disconnected, the power supply terminal of the train control center 4 is disconnected from the power supply.

[0046] The disconnection and connection of the CAN line contact 12 of the switch module 1 will affect the disconnection and connection of the CAN line end of the train control center 4 and the CAN line. Exemplarily, the CAN line end of the train control center 4 is usually connected to an external device through a CAN line. For example, the CAN line of the train control center 4 is generally connected to a track circuit and a signal device. The train control center 4 communicates with the track circuit and other signal devices through the CAN line to achieve the train control function. At this time, the CAN line contact 12 of the switch module 1 can be connected in series to the CAN line between the CAN line end of the train control center 4 and the CAN line end of the track circuit and the signal device, and is used to control the disconnection and connection of the CAN line end of the train control center 4 and the CAN line.

[0047] The first network port 21 of the switch 2 is electrically connected to the network end of the train control center 4, the second network port 22 of the switch 2 is electrically connected to the control module 3, and the third network port 23 of the switch 2 is electrically connected to the switch module 1. Among them, the switch 2 is a network device for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch 2. The switch 2 can control the disabling and enabling of its own network port, so the switch 2 can control the disabling and enabling of the first network port 21. Exemplarily, the switch 2 is also electrically connected to the network card. When the first network port 21 is disabled, the network end of the train control center 4 is disconnected from the network card, and the train control center 4 has no network. When the first network port 21 is enabled, the network end of the train control center 4 is electrically connected to the network card, and the network end of the train control center 4 is connected to the network.

[0048] Exemplarily, the first network port 21 of the switch 2 is electrically connected to the network end of the train control center 4 through a network cable, the second network port 22 of the switch 2 is electrically connected to the control module 3 through a network cable, and the third network port 23 of the switch 2 is electrically connected to the switch module 1 through a network cable.

[0049] The control module 3 is used to output a control signal, the switch module 1 is used to control the disconnection and connection of the power supply contact 11 and the CAN line contact 12 based on the control signal, and the switch 2 is used to control the disabling and enabling of the first network port 21 based on the control signal. Among them, the control module 3 refers to a functional module capable of performing logical control. Preferably, the control module 3 includes a control host, which is the core of the entire computer system and is responsible for executing program instructions and processing data. In other embodiments, the control module 3 may also include other devices that can execute program instructions and process data. This is not specifically limited here, but is only used as an example.

[0050] The control signal refers to an electrical signal that can control the switch module 1 and the switch 2. According to different control signals, the switch module 1 and the switch 2 can perform different actions to control the train control center 4 to turn off and on the power, disconnect and connect the CAN line, disconnect and connect the network, etc.

[0051] Through the above scheme, when the train control center 4 is functionally tested, a control signal can be sent through the control module 3, and then the switch module 1 can control the disconnection and connection of the power supply contact 11 and the CAN line contact 12 based on the control signal, and the switch 2 can control the disabling and enabling of the first network port 21 based on the control signal, so that there is no need for manual direct operation of the power supply, CAN line, and network cable of the train control center 4, and the train control center 4 can be controlled to turn off and on the power, disconnect and connect the CAN line, disconnect and connect the network, etc., so there is no risk of electric shock and the risk of users falling, and there is no need to plug and unplug the device, so there is no problem of easy damage to the device caused by frequent plugging and unplugging, and there is no problem of misalignment when restoring the connection after unplugging, and there is no need for multiple people to cooperate in the test, which is more convenient to use. The problem of high safety risk in the existing test of the train control center 4 is solved.

[0052] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the switch module 1 includes a network relay 13, the power supply contact 11 of the network relay 13 is electrically connected to the power supply end of the train control center 4 through the power line, and the CAN line contact 12 of the network relay 13 is electrically connected to the CAN line end of the train control center 4 through the CAN line. Among them, the network relay 13 is a device that can be remotely controlled through the network, so the network relay 13 can conveniently control the power supply end of the train control center 4 to connect or disconnect the power supply, and realize the train control center 4 to turn off and on the power supply. The network relay 13 can also conveniently control the train control center 4 to disconnect and connect the CAN line. Through the network relay 13, the control module 3 can remotely control the train control center 4 to turn off and on the power supply and disconnect and connect the CAN line through the controller.

[0053] In an optional embodiment of the present invention, the power line originally connected to the train control center 4 is connected to the power extension line connected to the power contact 11 of the network relay 13, and the CAN line originally connected to the train control center 4 is connected to the CAN line extension line connected to the CAN line contact 12 of the network relay 13. The extension line is used without damaging the original equipment of the train control center 4.

[0054] In an optional embodiment of the present invention, the power line includes a live wire, which is electrically connected to the power contact 11 of the network relay 13. By setting the network relay 13 on the live wire, when the network relay 13 disconnects the power contact 11, the train control center 4 is no longer energized, so that electric shock accidents will not occur, thereby ensuring personal safety.

[0055] In an optional embodiment of the present invention, the CAN line includes a CANL line, and the CANL line is electrically connected to the CAN line contact 12 of the network relay 13. In some embodiments, the CAN line also includes a CANH line. By electrically connecting the CANL line to the CAN line contact 12 of the network relay 13, the CAN line contact 12 of the network relay 13 can conveniently control the connection and disconnection between the train control center 4 and the CAN line.

[0056] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the network relay 13 is used to periodically send the power contact status information and the CAN line contact status information to the control module 3 through the switch 2. Among them, the power contact status information refers to the information indicating whether the power contact 11 is disconnected or connected, so it can reflect the connection status between the train control center 4 and the power supply. The CAN line contact status information refers to the information indicating whether the CAN line contact 12 is disconnected or connected, so it can reflect the connection status between the train control center 4 and the CAN line. By sending the power contact status information and the CAN line contact status information to the control module 3, it is convenient for the user to remotely know the current connection status between the train control center 4 and the power supply and the CAN line.

[0057] In an optional embodiment of the present invention, the control module 3 includes a control host interface 31. The control host interface 31 refers to a window for users to interact with the central control system, allowing users to control and manage various devices in the system through an intuitive and easy-to-use interface.

[0058] The control host interface 31 is used to send control signals to the network relay 13 and the switch 2. Specifically, the control host interface 31 is used to receive user operations and send control signals to the network relay 13 and the switch 2 based on the user operations. For example, control icons of the power contact 11, the CAN line contact 12, and the first network port 21 can be set on the control host interface 31. The user can change the state of the component corresponding to the control icon by operating the control icon. For example, operating the control icon corresponding to the power contact 11 makes the state of the power contact 11 disconnected, and then a control signal will be sent to the network relay 13 to disconnect the power contact 11.

[0059] The control host interface 31 is used to display the power contact status information and the CAN line contact status information; the control host interface 31 is also used to receive and display the first network port status information sent by the switch 2. The first network port status information refers to information indicating whether the first network port 21 is enabled or disabled. By displaying the power contact status information, the CAN line contact status information and the first network port status information on the control host interface 31, it is convenient for the user to remotely know the current connection status of the train control center 4 with the power supply, the CAN line and the network.

[0060] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the train control center 4 includes a first train control center system 41 and a second train control center system 42; the number of the first network ports 21 is two groups, one group of the first network ports 21 is electrically connected to the network end of the first train control center system 41, and the other group of the first network ports 21 is electrically connected to the network end of the second train control center system 42; the number of the power contacts 11 and the CAN line contacts 12 are both two groups, one group of the power contacts 11 and the CAN line contacts 12 are electrically connected to the power end and the CAN line end of the first train control center system 41, respectively, and the other group of the power contacts 11 and the CAN line contacts 12 are electrically connected to the power end and the CAN line end of the second train control center system 42, respectively. Therefore, the first train control center system 41 and the second train control center system 42 can be remotely controlled separately, and the test is relatively convenient, which solves the problem of high safety risk in the test of the existing train control center 4.

[0061] In some embodiments, the switch 2 is divided into two VLANs, which are respectively connected to Ethernet network segments A and B. The number of each group of first network ports 21 is two, one for connecting to Ethernet network segment A, and the other for connecting to Ethernet network segment B.

[0066] S120. The switch module controls the disconnection and connection of the power supply contact and the CAN line contact based on the control signal.

[0067] The disconnection and connection of the power supply contact of the switch module will affect the disconnection and connection of the power supply end of the train control center with the power supply. The disconnection and connection of the CAN line contact of the switch module will affect the disconnection and connection of the CAN line end of the train control center with the CAN line.

[0073] S210, the control host interface outputs control signals to the network relays and switches.
