Description

Technical Field

[0001] The present invention relates to the technical field of rail transit, and specifically, to a rail transit platform screen door transformation system and method. Background Art

[0002] In modern rail transit systems, the coordinated operation between the signal system and the platform screen door system is crucial to ensure the safe and punctual operation of trains. However, existing circuit designs often lack sufficient redundancy. Once the main control circuit fails, it may lead to the paralysis of the entire system, affecting the normal operation of trains and the safety of passengers.

[0003] In addition, most of the interlock release operations in existing rail transit systems rely on manual judgment and operation, resulting in low efficiency; and the existing single local control cannot directly and timely control the train in the case where the train needs to make a local turn-back at the platform. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a rail transit platform screen door transformation system and method, which transform the platform screen door through three modules: redundant circuit design, remote control, and dual local control, so as to ensure the operation, safety, and efficiency of the platform screen door system, and improve the reliability and stability of the platform screen door system.

[0005] To solve the above problems, the technical solution of the present invention is as follows:

[0006] A rail transit platform screen door transformation system includes a redundant circuit design module, a remote control module, and a dual local control module. The redundant circuit design module includes a main control circuit and a standby control circuit. When the main control circuit fails, the system can automatically detect the failure and switch to the standby control circuit to ensure the normal opening and closing of the platform screen door and the normal operation of the signal system; the remote control module is used to allow the control center to directly control the platform screen door in case of emergency; the dual local control module includes two local control panels, and the two local control panels achieve priority interlock, and each local control panel can control the platform screen door.

[0007] Preferably, the standby control circuit also has a fault diagnosis function, which can detect and repair the main control circuit during the switching process. When the main control circuit returns to normal, the system will automatically switch back to the main control circuit.

[0008] Preferably, the remote control module allows the control center to directly control the platform screen doors in case of emergency, including: after the train stops at the station, when the train doors or platform screen doors fail to open normally, the train sends an alarm message to the control center, and the dispatcher confirms the status of the train doors; when the train doors are in the "enabled" state, the dispatcher sends a remote door opening command to the train, or arranges for station personnel to press the platform door opening button to open the train doors and platform screen doors synchronously; when the train doors or platform screen doors fail to close normally, the train sends an alarm message to the control center, and the dispatcher confirms the status of the train doors; when the train doors are in the "enabled" state, the dispatcher sends a remote door closing command to the train, or arranges for station personnel to press the platform door closing button to close the train doors and platform screen doors synchronously; if the train doors are in the "disabled" state when the door opening and closing operations fail, the driver needs to board the train, cut off the ATC control and activate the "door enable bypass" switch to manually restore the door failure.

[0009] Preferably, the operations of the two local control panels are monitored by the human-machine interface HMI in the platform screen door electrical system, so that the platform screen doors can be controlled by operating the local control panels at both the head and the tail of the train.

[0010] Furthermore, the present invention also provides a method for retrofitting a rail transit platform screen door system, including the following steps:

[0011] Install a standby control circuit in the platform screen door system. When the main control circuit fails, the system can automatically detect the failure and switch to the standby control circuit;

[0012] If the system redundancy mode fails, further switch to the remote operation mode, allowing the control center to directly control the platform screen doors in case of emergency;

[0013] When the train makes a local turn-back at the platform, use the dual local control panels to directly control the train;

[0014] Debug and monitor the daily operation of the retrofitted rail transit platform screen door system.

[0015] Preferably, the step of further switching to the remote operation mode and allowing the control center to directly control the platform screen doors in case of an emergency when the system redundancy mode fails specifically includes: after the train stops at the station, when the train doors or the platform screen doors fail to open normally, the train sends an alarm message to the control center, and the dispatcher confirms the status of the train doors; when the train doors are in the "enabled" state, the dispatcher sends a remote door opening command to the train or arranges the station staff to press the platform door opening button to open the train doors and the platform screen doors synchronously; when the train doors or the platform screen doors fail to close normally, the train sends an alarm message to the control center, and the dispatcher confirms the status of the train doors; when the train doors are in the "enabled" state, the dispatcher sends a remote door closing command to the train or arranges the station staff to press the platform door closing button to close the train doors and the platform screen doors synchronously; if the train doors are in the "disabled" state when the opening and closing of the train doors fail, the driver needs to board the train, cut off the ATC control and activate the "door enable bypass" switch to manually restore the train door fault.

[0016] Preferably, the step of directly controlling the train using the dual local control panel when the train makes a local reversal at the platform specifically includes: the station staff operates the local control panel at one end of the subway platform to issue door opening and closing commands. After being received and processed by the logic signal interface box, the valid signals are sent to the platform screen door controller, and the platform screen door controller controls the screen doors to perform opening and closing actions; at the same time, the logic signal interface box sends a prohibition work command to the local control panel at the other end to keep the local control panel in the closed state; when the station staff closes the currently operated local control panel, the originally closed local control panel at the other end will restart and be in the working state.

[0017] Compared with the prior art, the present invention provides a transformation solution for the rail transit platform screen door system. By transforming the platform screen door system with three modules: adding redundant circuit design, remote control, and dual local control, when a fault occurs in the main circuit of the platform screen door system, the redundant circuit is switched in time; if the redundancy mode fails, the remote operation mode is further switched, and the operation personnel ensure the safety of the train entering and leaving the station, enabling the controlled train to ignore the fault status of the platform screen doors when entering or leaving the station; when the train makes a local reversal at the platform, the dual local panel is used to directly control the train. The three modules jointly ensure the operation, safety, and efficiency of the platform screen door system, significantly improving the reliability and stability of the platform screen door system, and having important significance for enhancing the safety and reliability of the rail transit system.

[0023] The present invention will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all fall within the protection scope of the present invention.

[0024] Specifically, the present invention provides a system for transforming a platform screen door of rail transit, as Figure 1 shown, the system includes a redundant circuit design module, a remote control module, and a dual local control module.

[0025] The redundant circuit design module includes a main control circuit and a standby control circuit. At the interface between the signal system and the platform screen door system, a main control circuit and a standby control circuit parallel to it are set. The main control circuit is responsible for daily signal transmission and instruction execution, while the standby control circuit is in a standby state and does not participate in daily operations. When the main control circuit fails, the system can automatically detect the failure and quickly switch to the standby control circuit to ensure the normal opening and closing of the platform screen door and the normal operation of the signal system. The standby control circuit can not only take over the work of the main control circuit, but also has a fault diagnosis function, and can detect and repair the main control circuit during the switching process. Once the main control circuit returns to normal, the system will automatically switch back to the main control circuit.

[0026] As Figure 2As shown in the figure, the remote control module is used to allow the control center to directly control the platform screen doors in case of emergency. After the train stops at the station, when the train doors or platform screen doors fail to open normally, the train sends an alarm message to the control center, and the dispatcher confirms the status of the train doors. If the train doors are in the "enabled" state, the dispatcher sends a remote door opening command to the train, or arranges for station personnel to press the platform door opening button to open the train doors and platform screen doors synchronously. When the train doors or platform screen doors fail to close normally, the train sends an alarm message to the control center, and the dispatcher confirms the status of the train doors. If the train doors are in the "enabled" state, the dispatcher sends a remote door closing command to the train, or arranges for station personnel to press the platform door closing button to close the train doors and platform screen doors synchronously. If the train doors are in the "disabled" state when the door opening and closing fail, the driver needs to board the train, cut off the ATC control, and activate the "door enable bypass" switch to manually restore the door failure.

[0027] As Figure 3 shown in the figure, the dual local control module includes two local control panels. At the other end of the platform where the local control panel has been installed, an additional local control panel is added. The two local control panels achieve priority interlock through signal processing of the logic signal interface box, and each local control panel can control the platform screen doors. At the same time, the operations of the two local control panels are monitored by the human-machine interface HMI in the platform screen door electrical system. On the premise that both the front and rear ends of the train can operate the local control panel to control the platform screen doors, fewer additional components are required, which is convenient for installation and suitable for the transformation of existing projects.

[0028] Furthermore, the present invention also provides a method for transforming a rail transit platform screen door, as Figure 4 shown in the figure, the method includes the following steps:

[0029] S1: Install a standby control circuit in the platform screen door system. When the main control circuit fails, the system can automatically detect the failure and switch to the standby control circuit;

[0030] Specifically, a main control circuit and a parallel standby control circuit are set in the platform screen door system. When the main control circuit fails, the system can automatically detect the failure and quickly switch to the standby control circuit to ensure the normal opening and closing of the platform screen doors and the normal operation of the signal system. The standby control circuit can not only take over the work of the main control circuit but also has a fault diagnosis function, which can detect and repair the main control circuit during the switching process. Once the main control circuit returns to normal, the system will automatically switch back to the main control circuit.

[0031] S2: If the system redundancy mode fails, further switch to the remote operation mode to allow the control center to directly control the platform screen doors in case of emergency;

[0032] Specifically, after the train stops at a station, when the train doors or platform screen doors do not open normally, the train sends an alarm message to the control center, and the dispatcher confirms the status of the train doors. When the train doors are in the "enabled" state, the dispatcher sends a remote door-opening command to the train or arranges for station staff to press the platform door-opening button to synchronously open the train doors and platform screen doors. When the train doors or platform screen doors do not close normally, the train sends an alarm message to the control center, and the dispatcher confirms the status of the train doors. When the train doors are in the "enabled" state, the dispatcher sends a remote door-closing command to the train or arranges for station staff to press the platform door-closing button to synchronously close the train doors and platform screen doors. If the train doors are in the "disabled" state when the door-opening and door-closing operations fail, the driver needs to board the train, cut off the ATC control, and activate the "door enable bypass" switch to manually restore the door fault.

[0033] S3: When the train makes a local reversal at the platform, use the dual local control panel to directly control the train.

[0034] Specifically, station staff operate the local control panel at one end of the subway platform to issue door-opening and door-closing commands. After being received and processed by the logic signal interface box, the valid signals are sent to the platform screen door controller, and the platform screen door controller controls the screen doors to perform the opening and closing actions. At the same time, the logic signal interface box sends a prohibition work command to the local control panel at the other end, making the local control panel at that end in the closed state. When the station staff close the currently operated local control panel, at this time, the originally closed local control panel at the other end will restart and be in the working state.

[0035] S4: Debug and monitor the daily operation of the transformed rail transit platform screen door system.

[0036] Specifically, after the equipment installation is completed, joint commissioning of the system is carried out. First, functional tests are performed on individual equipment to ensure its normal operation. Then, joint commissioning of the overall system is carried out to simulate various control scenarios and fault conditions, and check the effectiveness and reliability of redundant design, remote control, and dual local control. During the operation of the rail transit platform screen door system, the operation status of the platform screen doors and the working conditions of each device are monitored in real time through the monitoring system. Key attention is paid to the devices and parameters related to redundant design, remote control, and dual local control. Once any abnormal situation is found, it is analyzed and processed in a timely manner.

[0037] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific implementation manners. Those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention. Without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
