[0027] The following will combine the technical solutions, structural features, purposes achieved and effects of the embodiments of the present application. Figure 1 and Figure 2 The technical solutions, structural features, purposes achieved and effects of the embodiments of the present application will be described in detail.

[0028] It should be noted that the drawings are greatly simplified and use non-precise proportions, only to facilitate and clarify the purpose of assisting in the description of the embodiments of the present application, and are not used to limit the scope of the embodiments of the present application, and therefore do not have technical significance, any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes achieved by the present application, should still fall within the scope of the technical content disclosed by the present application.

[0029] It should be noted that, in this invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only the expressly listed elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0030] This embodiment discloses a control system for automatic door opening of trains on both sides of a platform, such as... Figure 1 As shown, the system includes a central signaling system and an Automatic Train Control (ATC) system. The ATC system controls the opening of train doors upon arrival at the station and includes an Automatic Train Protection (ATP) system (not shown in the figure) and a train onboard signal control system. The ATP system ensures the safety of train door opening. Specifically, when the train stops at the platform, the ATP system calculates the "door enable." When the ATP system detects that the train speed is 0 and the train is aligned with the platform, the "door enable" is enabled, and the train can open the doors. The train onboard signal control system sends a door opening command to the train. Only when the train receives the door opening command from the train onboard signal control system and the "door enable" is enabled will the doors open according to the command. The central signaling system and the train onboard signal control system communicate via a wireless communication system, thereby sending door control strategy information to the train onboard signal control system. The train onboard signal control system automatically controls the train door opening based on the door control strategy information. The door control strategy information can be flexibly set on the central signaling system according to different operational management needs.

[0031] After receiving the door control strategy information, the train's onboard signal control system generates a corresponding door opening command and sends it to the train. Simultaneously, the onboard signal control system also communicates with the Train Control Monitoring System (TCMS) to send the door control strategy information to the TCMS system. The TCMS system then sends the door control strategy information to the Onboard Passenger Information System (PIS). Before the train arrives at the platform, the onboard PIS system displays the door control strategy information on the PIS screen to indicate to passengers which door to use for disembarking, ensuring orderly disembarkation on both platforms.

[0032] According to the platform information of the next station reached by the train, the door control strategy information includes "both sides of the train door are opened simultaneously", "the left side of the train door is opened before the right side of the train door, and the interval time is N", "the right side of the train door is opened before the left side of the train door, and the interval time is M", "only the left side of the train door is opened, and the right side of the train door remains closed", and "only the right side of the train door is opened, and the left side of the train door remains closed", wherein the interval times M and N can be set according to requirements, and the above-mentioned door control strategy information can also be flexibly modified on the central signal system before the train arrives at the station, and the modified door control strategy is immediately updated to the train-mounted signal system.

[0033] Further, after the train executes the door opening instruction, the train-mounted signal system controls the opened train door to be closed after a specified time, so that both sides of the train door are closed, or the vehicle driver manually presses the vehicle door closing button to close the opened door, so that both sides of the train door are closed; the specified time is flexibly set according to requirements. Alternatively, a total door closing button is provided, which simultaneously controls both sides of the train door, and when both sides of the train door are opened simultaneously, the total door closing button is pressed to simultaneously close both sides of the train door.

[0034] The embodiment also discloses a control method of automatic door opening of a train at a double-sided platform, which is based on the above-mentioned control system, as shown in the figure, and specifically includes the following steps: Figure 2

[0035] S1, setting a door control strategy of a train when reaching a next platform on a central signal system; wherein the door control strategy can also be changed on the central signal system before the train arrives at the station;

[0036] S2, the central signal system sends the door control strategy to a train-mounted signal control system through a wireless communication system;

[0037] S3, after the train arrives at the station, the train-mounted signal control system sends a door opening instruction to the train according to the door control strategy; when the ATP system monitors that the train speed is 0 and the train is aligned with the platform, the "door enable" is in an allowed state, and at this time, the train opens the door according to the door opening instruction;

[0038] Wherein, after receiving the door control strategy information, the train-mounted signal control system also sends the door control strategy to a train TCMS system, and then sends the door control strategy to a vehicle-mounted PIS system by the train TCMS system; before the train arrives at the station, the vehicle-mounted PIS system displays the door control strategy on a vehicle-mounted PIS screen to prompt passengers to get off from which side of the train door;

[0039] S4, a certain period of time after the train door is opened, the train-mounted signal control system automatically closes the opened door, or the driver closes the door according to requirements through a vehicle door closing button.
