[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figure 1 and Figure 2 As shown, the utility model provides a rail vehicle platform side door control system, including a platform side detection device 1, a left door control circuit, and a right door control circuit.

[0036] The platform side detection device 1 is used to identify the platform side position where the vehicle is currently parked, that is, to identify whether the platform is on the left or right side. In this embodiment, the platform side detection device 1 is installed in the vehicle, which is convenient for the driver to control and perform daily maintenance.

[0037] The left door control circuit and the right door control circuit are the same, both of which include a door opening button DVS, and a door opening enabling relay DOER is connected in parallel with the door opening button DVS. Specifically, the right door control circuit includes a right door opening button DVS1 and a right door opening enabling relay DOER1, and the left door control circuit includes a left door opening button DVS2 and a left door opening enabling relay DOER2.

[0038] The platform side detection device 1 is connected to the right door opening enable relay DOER1 and the left door opening enable relay DOER2, both of which use normally open contacts. The platform side detection device 1 outputs a door opening enable signal to the door opening enable relay DOER on the current platform side according to the identified platform side position. If the platform side is identified as the right side, the door opening enable signal is output to the right door opening enable relay DOER1, and the right door opening enable relay DOER1 on the platform side is controlled to be energized and closed, and the right door control circuit is connected, and all the doors on the right side are automatically opened, while the left door opening enable relay DOER2 on the non-platform side (such as the left side) is disconnected due to power failure, and all the doors on the non-platform side (left side) cannot be opened.

[0039] In this way, the platform side detection device 1 automatically identifies the platform position of the current stop station, whether it is the left platform or the right platform, or the double-sided platform, and then the platform side detection device 1 outputs an enable signal to the identified right door opening enable relay DOER1 or the left door opening enable relay DOER2 on the platform side, controls the right door opening enable relay DOER1 or the left door opening enable relay DOER2 on the platform side to be energized and closed, and then connects the door control circuit on the platform side, and all the doors on the platform side are automatically opened, while the door opening enable relay DOER on the non-platform side remains in a power-off and disconnected state because it does not receive the enable signal, and the door control circuit on the non-platform side is disconnected. Even if the driver makes an error operation, the door on the non-platform side will not be opened, thereby achieving the purpose of automatically opening the platform side door when the EMU stops at the station, ensuring that only the door on the platform side can be opened, effectively realizing accurate door opening control, without manual judgment and operation, and effectively preventing the driver from accidentally opening the non-platform side door during manual operation, thereby ensuring the safety of passengers and property.

[0040] In the present embodiment, it is further preferred that the right door opening enabling relay DOER1 is connected in series with the door opening mode selection button DOAS1, the left door opening enabling relay DOER2 is connected in series with the door opening mode selection button DOAS2, the right door opening enabling relay DOER1 and the door opening mode selection button DOAS1 are connected in parallel with the right door opening button DVS1, and the left door opening enabling relay DOER2 and the door opening mode selection button DOAS2 are connected in parallel with the left door opening button DVS2. The door opening mode selection buttons DOAS1 and DOAS2 are used to switch between manual control mode and automatic control mode, including "automatic position" and "manual position". If the driver chooses manual control mode, the circuit of the corresponding right door opening enable relay DOER1 or left door opening enable relay DOER2 is disconnected, and the driver presses the right door opening button DVS1 or the left door opening button DVS2 to open the door. If the driver chooses automatic control mode, the circuit of the right door opening enable relay DOER1 or the left door opening enable relay DOER2 is connected, the right door opening button DVS1 and the left door opening button DVS2 remain disconnected, and the right door opening enable relay DOER1 and the left door opening enable relay DOER2 are controlled by the enable signal of the platform side detection device 1.

[0041] like Figure 2 As shown, taking the right door opening as an example, the right door control circuit includes a right door opening button DVS1, a right door opening enabling relay DOER1 and a door opening mode selection button DOAS1 are connected in parallel with the right door opening button DVS1, and a circuit breaker DN1, a diode Q1 and MCR1 are also connected in series with the right door opening button DVS1 in the right door control circuit. Under normal conditions, the circuit breaker DN1 is always protected in the connected state, and after the driver inserts the control key, the MCR1 is also always protected in the connected state.

[0042] When the door opening mode selection button DOAS1 is in the "automatic position" and when the platform side detection device 1 determines that the right side is the platform side, the platform side detection device 1 outputs an enable signal to the right door opening enable relay DOER1, controls the right door opening enable relay DOER1 to be energized, closes its normally open contacts, and then connects the right door control circuit, and all the right doors open automatically. At the same time, the left door opening enable relay DOER2 loses power, the normally open contacts remain disconnected, the left door control circuit is disabled (shielded), and the left door cannot be opened automatically, thereby realizing the function of automatic opening of the platform side door.

[0043] In this embodiment, preferably, the platform side detection device 1 includes an entry judgment module and a signal sending module. The entry judgment module is used to detect the distance between the vehicle body and the platform after entering the station and judge the platform side position according to the distance. When the distance between the vehicle body and the platform is less than a set value, the platform on this side is judged to be the platform side of the current stop station. The signal sending module outputs a door opening enable signal to the door opening enable relay DOER on the corresponding platform side according to the result information of the entry judgment module.

[0044] In this embodiment, it is further preferred that the station entry judgment module includes a distance detection unit and a judgment and analysis unit. The distance detection unit includes at least one distance sensor 2 respectively arranged on both sides of the front and rear of the vehicle, and the distance sensor 2 is used to detect the distance between the vehicle body and the platform.

[0045] like Figure 1 As shown, a distance sensor 2 is installed on the right side of the front of the train, a distance sensor 3 is installed on the left side of the front of the train, a distance sensor 4 is installed on the right side of the rear of the train, and a distance sensor 5 is installed on the left side of the rear of the train. A total of four distance sensors are installed on the entire train.

[0046] The distance sensor is connected to the judgment and analysis unit, and the judgment and analysis unit is connected to the signal sending module. The judgment and analysis unit pre-stores a set value of the distance between the vehicle body and the platform. The four distance sensors 2, 3, 4, and 5 respectively detect the distance between the left and right sides of the front and rear of the vehicle and the corresponding left and right platforms. The distance sensor sends the detected data to the judgment and analysis unit. When the detected distance is less than the set value, the judgment and analysis unit determines that the side is the platform side and sends the result information to the signal sending module, and the signal sending module sends an enable signal to the door opening enable relay DOER on the corresponding platform side.

[0047] In this embodiment, four distance sensors are used to detect the distance between the two sides of the vehicle body and the corresponding side platforms, and then the platform side position of the current stop platform is determined. The control logic is simple and reliable.

[0048] The rail vehicle platform side door control system provided by this embodiment has the following advantages:

[0049] (1) The door control system automatically identifies the platform side position of the EMU when it stops through the platform side detection device, enables the platform side door opening control circuit, and blocks the non-platform side door opening control circuit, so as to achieve the purpose of automatically opening the platform side door when the EMU stops at the station without manual judgment and operation, preventing the driver from accidentally opening the non-platform side door during manual operation, thereby ensuring the safety of passengers and property.

[0050] (2) The control circuit structure provided by the door control system is simple, reliable, and practical. It can effectively realize accurate door opening control and effectively avoid the hidden danger of accidental opening of non-platform side doors.

[0051] (3) The door control system adds distance sensors on both sides of the front and rear cars to determine the distance between the two sides of the car body and the corresponding side platform, and then determines the platform side position of the current stop platform. The control logic is simple and reliable.

[0052] Embodiment 2:

[0053] On the basis of the technical solution provided in Example 1, it is further preferred in this embodiment that the platform-side detection device 1 also includes a vehicle information acquisition module, which is connected to the vehicle information system, and the acquired vehicle information includes the train number, time and the name of the current stop.

[0054] The platform side detection device 1 also includes a comparison module, which is used to compare the platform side position determined by the entry judgment module with the acquired vehicle information. When the comparison results are consistent, the signal sending module outputs a door opening enable signal. For example, when the vehicle enters the station, when the distance between the distance sensor 2 on the right side of the front of the vehicle and the distance sensor 4 on the right side of the rear of the vehicle and the platform is less than the set value, the current platform is judged to be the right platform. At the same time, the vehicle information acquisition module also obtains the train number of this train, the current entry time, and the name of the current stop. The comparison module analyzes whether the information feedback from the distance sensor matches the acquired vehicle information, and finally determines which side is the platform side (left or right). The platform side detection device 1 outputs a corresponding door opening enable signal according to the platform side position finally determined, and controls the right door opening enable relay DOER1 or the left door opening enable relay DOER2 to be energized.

[0055] In this way, misjudgment due to damage to the distance sensor can be avoided, the accuracy of identifying the platform side position can be ensured, and the driver can be further prevented from accidentally opening the non-platform side door during manual operation, thereby ensuring the safety of passengers' lives and property.

[0056] In this embodiment, the acquired vehicle information further includes vehicle speed information. Only when the vehicle speed is 0, the signal sending module in the platform-side detection device 1 will output a door opening enable signal, thereby ensuring the safety of vehicle operation.

[0057] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
