[0090] The following is a further detailed description of a test method for maintaining human control priority for lateral entry of the CTCS-2 on-board train control system proposed by the present invention in combination with the accompanying drawings and specific implementation methods. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the implementation method of the present invention. In order to make the purposes, features and advantages of the present invention more obvious and easy to understand, please refer to the accompanying drawings. It should be noted that the structure, proportion, size, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no technical substantive significance. Any modification of the structure, change in the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope of the technical content disclosed by the present invention.

[0091] The basic concepts involved in the present invention are introduced as follows: the track circuit realizes the track occupancy and train integrity check, and continuously transmits the number of idle block sections ahead to the train by sending the track circuit code.

[0092] The low-frequency information code is used to indicate the number of free blocks ahead and the target speed (including the lateral speed limit of the switches on the route, the opening speed for guidance and shunting, etc.), and is an important continuous information of the CTCS-2 on-board train control system.

[0093] The UU code (18.0Hz) locomotive signal displays a double half yellow light, requiring the train to run at a limited speed, and the ground signal indicating that the train is approaching opens the approach through the lateral position of the switch.

[0094] The UUS code (19.1Hz) locomotive signal displays a double half yellow flash, requiring the train to run at a limited speed. The ground signal indicating that the train is approaching has an open route through the lateral position of switch No. 18 and above, and one signal is open through the switch straight or the lateral position of switch No. 18 and above; or the ground signal indicating that the train is approaching the divergent switch has an open route through the lateral position of switch No. 18 and above.

[0095] The HU (26.8Hz) code locomotive signal displays a half yellow and half red light, requiring timely stopping measures. It indicates that the train's approach ahead has not been established, and the train's running speed is 0 km / h at the end of the approach.

[0096] The uncoded (27.9Hz, 25.7Hz, 0Hz) locomotive signal displays a white light.

[0097] The test requirements of this embodiment are as follows: In FS mode, when the following conditions are met at the same time, the vehicle-mounted equipment switches from machine control priority to human control priority:

[0098] 1. The station block receives UU / UUS;

[0099] 2. UU, UUS, HU or no code received in the station after the announcement of no carrier frequency;

[0100] 3. The station is blocked from exiting;

[0101] 4. The LMA position is less than or equal to the exit block terminal position.

[0102] Based on the test requirement description, the test scenario or test case is defined. The specific test method is as follows:

[0103] Combination Figure 1 to Figure 3 As shown, this embodiment provides a test method for maintaining human control priority for lateral entry of a CTCS-2 on-board train control system, including:

[0104] The on-board equipment controls the train to run to the switch siding receiving track in FS mode and receives the low-frequency code information sent from the track circuit.

[0105] It can be understood that in FS mode (Full Supervision mode), the on-board equipment uses the received track circuit data (for example, low-frequency code information) and transponder message data to calculate the continuous speed curve of the target speed distance, so as to monitor the train operation on the track line based on this continuous speed curve.

[0106] Determine the turnout type and test case according to the low-frequency code information;

[0107] Execute the test case to obtain the test result;

[0108] The test cases include:

[0109] Execute the movement authorization length at the location of the outbound signal;

[0110] Receive the no-code / HU low-frequency code sent by the track circuit in the forward branch area;

[0111] Receiving the HU low-frequency code sent by the track circuit in the station;

[0112] Determine whether to reopen the outbound signal;

[0113] Check the DMI (human-machine interface) of the on-board equipment to determine whether the on-board train control system is in the human control priority mode to obtain the test result.

[0114] This embodiment designs a test method for maintaining human control priority for lateral entry of the CTCS-2 on-board train control system according to the actual operation scenario of the CTCS-2 on-board train control system, thereby realizing the test of the human control priority mode function for lateral entry of trains, ensuring the completeness of the test coverage and effectively improving the test efficiency.

[0115] It can be understood that, in this embodiment, after receiving the corresponding low-frequency code, the on-board equipment of the train controls the operation of the train according to the corresponding low-frequency code.

[0116] In this embodiment, when the low frequency code information is a UU low frequency code, the turnout type is a turnout with a turnout code less than or equal to 12, and this type of turnout has a low speed limit. When the low frequency code information is a UUS low frequency code, the turnout type is a turnout with a turnout code greater than or equal to 18, and this type of turnout has a high speed limit.

[0117] Please continue to refer to Figure 2 and Figure 3 As shown, this embodiment provides the following two types of test cases.

[0123] The mobile authorization length is at the location of the exit signal;

[0124] The forward switch area receives track circuits that send no code / HU low-frequency code;

[0125] The station receives the HU low-frequency code sent by the track circuit;

[0126] Whether to reopen the outbound signal;

[0127] Check whether the DMI shows that the vehicle system is in human control priority.

[0128] When the train runs to a turnout with a turnout code less than or equal to 12, a second test case is executed, where the second test case includes a plurality of sub-test cases divided according to the effective equivalence class division method.

[0129] That is, for the train receiving signals at the lateral position of turnout No. 12 and below (the siding entry section receives UU code), consider the situations where the switch area sends no code or HU code, and the situations where the exit signal is closed or open, test whether the train (CTCS-2 on-board train control system) is in the human control priority mode.

[0197] Step S805: Determine, according to the balise message sent by the track circuit, that the signal type is an exit signal with a source balise;

[0198] Step S806, reopen the exit signal;

[0199] Step S807 checks the DMI of the vehicle-mounted device to determine whether the vehicle-mounted train control system is in the human control priority mode, and obtains the test result.

[0200] In this embodiment, after executing the corresponding test case, if it is checked that there is no driving curve on the DMI of the vehicle-mounted device, it is determined that the vehicle-mounted train control system is switched from the machine control priority mode to the human control priority mode.

[0201] It is understandable that railway signal technology is an essential means to ensure the safety of train operation, achieve effective train control, improve throughput, and provide real-time information to operation managers. It is one of the key technologies for existing line technology and high-speed railway construction.

[0202] The on-board train control system is a system that automatically controls the entire operation process or part of the operation of the train. It can monitor, control and adjust the status baseline of the train speed and braking mode according to the objective conditions and actual situation of the train running on the line. At present, according to the human-machine relationship, it can be divided into equipment braking priority mode and driver braking priority mode.

[0203] The driver brake priority mode is that the driver controls the train speed according to the mode curve, and the equipment does not interfere with the driver's normal driving. Only when the train is overspeeding, the equipment takes effective deceleration measures to ensure the safety of train operation. The release of the equipment brake must be allowed by the equipment and confirmed by the driver.

[0204] The equipment braking priority mode is that the equipment can automatically control the train deceleration according to the mode curve and ensure the safety of train operation. Once the relief conditions are met after the equipment is normally braked, it will automatically release in time.

[0205] In the equipment braking priority mode, the on-board equipment realizes automatic speed control during the deceleration process by automatically triggering different levels of common brakes; when the train speed is lower than the relief speed, the on-board equipment automatically stops outputting the corresponding level of common brake commands without the need for manual intervention by the driver.

[0206] In the driver's brake priority mode, the driver is responsible for controlling the entire driving process including deceleration; after the on-board equipment implements normal braking, when the train speed is lower than the relief speed, the on-board equipment prompts the driver to allow relief information, and the driver releases the normal braking after pressing the relief button.

[0207] The common point between the driver brake priority mode and the equipment brake priority mode is that they are consistent in the settings of the maximum normal brake and emergency brake to ensure the safety of train operation. When the train is receiving and running in the station, the on-board equipment currently in the equipment brake priority mode will also be switched to the driver brake priority mode.

[0208] The difference between the two modes is that the equipment braking priority mode adds and subtracts the commonly used level 1 braking and the commonly used level 4 braking, which is used to replace the driver's braking operation for trains running in the section.

[0209] On the other hand, the present invention further provides an electronic device, including a processor and a memory, wherein a computer program is stored in the memory, and when the computer program is executed by the processor, the method described above is implemented.

[0210] In other aspects, the present invention further provides a readable storage medium, wherein the readable storage medium stores a computer program, and when the computer program is executed by a processor, the method described above is implemented.

[0211] In addition, it is understandable that the above test method can also be that the CTCS-2 level train control system operates independently to test whether the siding entry is switched to the human control priority mode.
