[0002] Rail transit vehicles have the ability to travel in both directions, and are mostly in the form of 4 or 6 trains, consisting of trailers and motor cars, with the first and last trains being trailers with driver consoles. Depending on the different travel directions of the train, the driver can view the current train operation status information on the human-machine interface unit (i.e., vehicle display screen) on the corresponding end console, and send setting instructions through the soft buttons on the display interface to cooperate with the vehicle control unit to complete the control functions of various systems.

[0003] When operating the soft button on the human-machine interface unit, the display screen software can modify the style and related icons of the soft button on the interface according to the soft button operation to help the driver understand the current control function execution status. At present, there is no soft button status feedback communication interface between the screens at both ends of the train and between the screen and the vehicle controller in the industry. As a result, after operating the soft button on one end of the screen, only the soft button status of the screen at this end can be modified, and the corresponding soft button status of the display screen at the other end cannot be modified synchronously. As a result, the soft button status of the display screens at both ends is inconsistent. During operation, when the driver switches ends, it is easy to cause ambiguity and cause the driver to operate incorrectly. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0018] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0019] According to one aspect of the present invention, an embodiment of the present invention provides a dual-end display screen control method, such as Figure 1 As shown, it may include the steps of: S1, in response to the first display screen or the second display screen receiving an operation signal for a soft button, generating a control instruction based on the operation signal and sending the control instruction to a controller; S2, in response to the controller receiving the control instruction, sending the control instruction to the corresponding subsystem; S3, in response to the subsystem receiving the control instruction, acquiring an operating state and sending an operating state feedback signal to the controller based on the operating state; S4, in response to the controller receiving the operating status feedback signal, sending the operating status feedback signal to the first display screen and the second display screen to update the status of the soft button based on the operating status feedback signal.

[0020] The solution proposed in the present invention synchronizes the signal based on the operation instruction feedback of the display screen at either end to the display screens at both ends, so that after the soft button is operated on the display screen at either end of the locomotive, the two end screens can synchronously update the corresponding soft button status, so that the soft button status in the display screens at both ends always remains consistent.

[0021] In some embodiments, the display screen will display the current vehicle operation status, system parameters and device status in real time in the form of numerical values, icons and button styles, and a feedback signal receiving interface is set to receive the soft button status feedback signal sent by the controller to the display screen. The vehicle controller and the display screen communicate using a bus, and the bus bandwidth used can meet the signal transmission requirements, including but not limited to 485, MVB, and Ethernet buses.

[0022] In some embodiments, Figure 2As shown, when the staff operates the soft button on the display screen at either end, the display screen sends a pulse setting instruction to the vehicle controller. At this time, the vehicle controller will update the corresponding setting instruction sent to the subsystem according to the pulse setting instruction, and feedback the corresponding soft button status to the display screen. The dual-end display screen can update the corresponding soft button status and subsystem status according to the soft button status feedback from the vehicle controller and the status signal feedback from the subsystem, thereby achieving the purpose of synchronous update of the soft button status of the dual-end screens.

[0023] In some embodiments, generating a control instruction based on the operation signal and sending it to a controller further includes: Determine whether there is a timer currently; In response to the absence of a timer, sending the control instruction to a controller; A timer is started and the control instruction is cleared after a preset time period.

[0024] In some embodiments, it also includes: In response to the existence of the timer, clear the current control instruction and close the current timer; Sending the generated control instruction to a controller; A timer is started and the control instruction is cleared after a preset time period.

[0025] Specifically, Figure 3 As shown, the display screen, controller, and subsystem controller can exchange data through the MVB bus. The setting instruction sent by the display screen is in the form of a 3s pulse, and the setting instruction is determined by judging whether there is a timer at present. If so, the current timer is turned off and the current setting instruction is cleared. A new timer is restarted, and the setting instruction is resent using the control instruction sending port. The setting instruction is automatically cleared after 3s. In this way, the latest instruction can be determined according to the timer, and the screens at both ends synchronously display the setting information according to the setting instruction sent by the latest soft button, ensuring that the current page effect is the final setting state.

[0026] In some embodiments, in response to the controller receiving the operating status feedback signal, sending the operating status feedback signal to the first display screen and the second display screen further comprises: The operation status feedback signal is received by using the feedback signal receiving interfaces corresponding to the first display screen and the second display screen respectively.

[0027] Specifically, Figure 4As shown, when the controller receives the display screen pulse signal, it will run the soft button status feedback logic, that is, convert the signal into a high level and store it in the corresponding setting variable of the end screen for logical judgment. If there is a high level signal, the instruction will be sent to the corresponding subsystem, the subsystem will execute the corresponding action and send the status feedback signal, and the controller will synchronously send the status feedback signal to the display screens at both ends.

[0028] In some embodiments, it also includes: The first display screen or the second display screen is refreshed according to a first preset period.

[0029] In some embodiments, it also includes: The control instruction sending port is refreshed according to a second preset period, wherein the second preset period is not greater than half of the first preset period.

[0030] In some embodiments, it also includes: The controller runs the soft button state feedback logic according to a third preset cycle, and sends an operation state feedback signal to the feedback signal receiving interface according to a fourth preset cycle, wherein the sum of the third preset cycle and the fourth preset cycle is not greater than half of the second preset cycle.

[0031] Specifically, the refresh cycle of the display screen page (first preset cycle) is ≤256ms, the refresh cycle of the control instruction sending port between the controller and the display screen (second preset cycle) is ≤half of the display screen page refresh cycle, the controller runs the soft button state feedback logic according to the third preset cycle, and sends the operation state feedback signal to the feedback signal receiving interface according to the fourth preset cycle, the third preset cycle + the fourth preset cycle is ≤half of the refresh cycle of the control instruction sending port, so as to avoid slow refresh of the soft button state, causing a stuttering visual effect and affecting the operation experience.

[0032] For example, the refresh cycle of the display page can be 256ms, and the display screens at both ends refresh the current vehicle and system status from the same port in real time according to the corresponding cycle, modify the page button style and signal parameters, and use it for human-machine interface display. The refresh cycle of the signal between the display screen and the controller is 128ms, the cycle of the controller running feedback logic is 10ms, and the refresh cycle from the controller to the display screen port is 32ms.

[0033] The solution proposed by the present invention synchronizes the signal of the operation instruction feedback based on the display screen at either end to the display screen at both ends, so that after the soft button is operated on the display screen at either end of the locomotive, the two end screens can synchronously update the corresponding soft button status, so that the soft button status in the display screens at both ends is always consistent. It is also possible to modify the button style, icon and data parameters of the display screen interface at both ends at the same time according to the last setting instruction. It is ensured that the current display information of the two end screens is the final setting status of the vehicle and system, thereby improving the operation efficiency.

[0035] In some embodiments, generating a control instruction based on the operation signal and sending it to a controller further includes: Determine whether there is a timer currently; In response to the absence of a timer, sending the control instruction to a controller; A timer is started and the control instruction is cleared after a preset time period.

[0036] In some embodiments, it also includes: In response to the existence of the timer, clear the current control instruction and close the current timer; Sending the generated control instruction to a controller; A timer is started and the control instruction is cleared after a preset time period.
