Description

Technical Field

[0001] The present invention relates to the field of safety control, and particularly to a safety control system and method for depot doors in the full-automatic driving mode of urban rail transit. Background Art

[0002] With the continuous development of technology, rail transit can achieve fully automatic unmanned driving (Fully Automatic Operation, FAO). There is an interface between the interlocking subsystem in FAO and the depot doors to control and monitor the status of the depot doors, and transmit the door status to the Train Integrated Automation System (TIAS) and Zone Controller (ZC) through network devices. When the depot door is in the open and locked state, the train is allowed to conduct static and dynamic tests. After the departure signal is opened, the Movement Authority (MA) calculated by the ZC for the train can extend out of the depot.

[0003] In the current protection technical solution for depot doors, there is still a protection blind spot for depot doors in the "bypass" state. For example, when the depot door is in the "bypass" state due to a door failure, the signal system no longer checks the status of the depot door and defaults the door to the open state. The interlocking can arrange the departure route and open the departure signal, and the ground ATP (Automatic Train Protection) can calculate the Movement Authority (MA) for the train to depart from the depot, and the train departs normally. In this scenario, if the depot door is in the closed state and the door bypass is executed, it may cause the train in the FAO driving mode to collide with the depot door.

[0004] Therefore, how to avoid the safety hazards caused by the signal system defaulting the depot door to the open state when the depot door is in the "bypass" state has become an urgent problem to be solved. Summary of the Invention

[0048] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0049] First, the following content is introduced:

[0050] Figure 1 It is a schematic diagram of the MA for opening the depot door in the current FAO system provided by the related art. When the depot door is opened, the outbound route can be selected and arranged, and the CK01 signal is opened to allow the train to leave the depot.

[0051] Optionally, the interlocking system monitors in real time whether the depot door is in the open state or the closed state, and whether the field / section route can be selected and arranged. When selecting and arranging the CK01 to CK02 route and opening the CK01 signal, the interlocking system monitors that the depot door is open and locked. When the depot door is open and locked, the CK01 to CK02 route can be arranged, the CK01 signal is opened, the zone controller ZC sends the information that the depot door has been opened to the train, and the movement authorization calculated for the train can leave the depot to the front of the CK02 signal and retract the safety margin, and the train can leave the depot normally.

[0052] Figure 2 It is a schematic diagram of the MA for the garage door to close under the current FAO system provided by the related technology. When the garage door is closed, the outbound route cannot be selected or arranged, the CK01 signal is closed, and the train is not allowed to leave the depot.

[0053] Optionally, when the depot door is in the closed state, the outbound route cannot be selected, arranged, or opened. The zone controller ZC sends the information that the depot door is closed to the train, calculates the moving authorization for the train to the front of the CK1 signal and retracts the safety margin, and the on-board ATP protects the train and does not allow it to leave the depot.

[0054] Figure 3 It is a schematic diagram of the MA for the garage door to be bypassed and the depot door to be open under the current FAO system provided by the related technology. When the garage door is bypassed and the depot door is in the open state, the interlocking no longer checks the state of the garage door, the outbound route can be selected and arranged, and the CK01 signal can be opened, allowing the train to leave the depot.

[0055] Optionally, when the garage door has been opened but the signal system cannot receive the open state of the garage door, the open state of the garage door is bypassed through the manual bypass switch of the garage door. When the garage door system collects that the manual bypass state of the garage door is valid and the signal system collects that the bypass is valid, it is considered that the garage door is open and locked, and the train leaves the depot normally.

[0056] Figure 4 It is a schematic diagram of the MA for the garage door to be bypassed and the depot door to be closed under the current FAO system provided by the related technology. When the garage door is bypassed and the depot door is in the closed state, the interlocking no longer checks the state of the garage door, the outbound route can be selected and arranged, and the CK01 signal can be opened, allowing the train to leave the depot.

[0057] Optionally, when the garage door has been closed but the signal system cannot receive the closed state of the garage door, the closed state of the garage door is bypassed through the manual bypass switch of the garage door. When the garage door system collects that the manual bypass state of the garage door is valid and the signal system collects that the bypass is valid, it is considered that the garage door is open and locked. At this time, the train will try to leave the depot and ram the garage door. Therefore, in the current protection technical solution for the garage door, there is still a protection blind area for the garage door in the "bypass" state. For example, if the garage door is in the "bypass" state due to a door failure, the signal system will default that the garage door is in the open state, allowing the train to leave the depot normally. In this scenario, if the garage door is in the closed state and the door bypass is executed, it may cause the train in the FAO driving mode to ram the garage door.

[0058] The present invention provides a safety control system and method for the depot door in the full-automatic driving mode of urban rail transit, which can improve the safety of the unmanned automatic driving system.

[0059] The following describes the safety control system for the depot door in the full-automatic driving mode of urban rail transit provided by the present invention:

[0062] Optionally, the way for the user to determine that the garage door has been opened may be to manually observe whether the garage door has been opened.

[0063] In one embodiment, Figure 6 FIG. Figure 5 is a schematic diagram of a garage door control box provided by the present invention. The garage door control module may be a garage door control box, including:

[0064] Light display status: door opening light, door closing light, bypass light, and fault light;

[0065] Mode switch: automatic, bypass, and manual;

[0066] Operation buttons: manual door opening button, manual door closing button, manual door open confirmation button, and manual door close confirmation button.

[0067] Optionally, in the garage door control box, "manual door open confirmation" and "manual door close confirmation" relay contacts are respectively connected in series in the bypass circuit of the garage door system. "Manual door open confirmation button" and "manual door close confirmation button" are added in the operation box. The two buttons and the door bypass mode switch are sealed in an operation box. When the garage door needs to perform a bypass operation due to a fault, after the user is authorized, the seal can be broken. First, the bypass mode switch is turned on (indicating that the state of the garage door is in a bypass state), and then the "manual door opening button" or "manual door closing button" is activated. After the operation is completed, the operator confirms the state of the garage door and activates the corresponding "manual door open confirmation button" and "manual door close confirmation button".

[0068] Optionally, the first input may be to activate the "manual door open confirmation button" in the garage door control box.

[0069] Optionally, the activation of the "manual door close confirmation button" may be that the user presses the "manual door close confirmation button".

[0070] The signal system detection module 520 is configured to send a first message to the interlock when it detects that the garage door control module has received the first input. The first message is at least used to indicate that the state of the garage door is in a bypass state and the garage door has been opened.

[0078] Optionally, in the present invention, through the garage door control module, in the state where the garage door is bypassed, the user can actively input information determining that the depot door is open (for example, the user presses the "manual door open confirmation button" on the garage door control box). When the garage door control module receives the information determining that the depot door is open, it sends information that the depot door is in a bypass state and the depot door is open to the interlock, and the interlock sends this information to the area controller ZC, and then the area controller ZC sends this information to the on-vehicle ATP of the train. After receiving this information, the on-vehicle ATP allows the train to perform static tests, dynamic tests, and enter and leave the depot.

[0079] The garage door control module described in the present invention allows the user to actively input information determining that the depot door is open in the state where the garage door is bypassed, transmits this information through the signal system detection module, the interlock, and the area controller ZC, and finally enables the on-vehicle ATP of the train to receive information that the garage door is in a bypass state and the garage door is open. The on-vehicle ATP allows the train to perform static tests, dynamic tests, and enter and leave the depot, effectively avoiding potential safety hazards caused by the signal system defaulting that the depot door is open when the garage door is in the "bypass" state, and realizing the safety protection of the garage door by the system.

[0080] Optionally, the garage door control module is specifically configured to: in the case where the state of the depot door is in a bypass state and the depot door is closed, receive a second input from the user to open the depot door, and after the depot door is opened, receive a first input from the user to determine that the depot door is open.

[0093] Step 740: After the interlock receives the information that the library door is in the bypass state and determines that the library door has been opened, it sends this information to the area controller ZC;

[0094] Step 750: The area controller ZC sends the status information that the library door has been opened to the train;

[0095] Step 760: After the train receives the status information that the library door has been opened, when the forward route and signal conditions are met, the on-board ATP allows the train to leave the depot.

[0096] Optionally, when the garage door is in the bypass state and the depot door is closed, the user can control the opening of the depot door through the garage door control module. After the depot door is opened, the user confirms that the depot door has been opened through the garage door control module. After receiving the information that the depot door is in the bypass state and it is determined that the depot door has been opened, the interlock sends this information to the zone controller ZC, and then the zone controller ZC sends the depot door opening information and the information that the depot door is in the bypass state to the on-board ATP of the train.

[0106] Step 850: After the train receives the status information that the depot door has been opened, when the forward route and signal conditions are met, the on-board ATP allows the train to leave the depot.

[0107] Optionally, when the garage door is in the bypass state and the depot door is open, the user can confirm that the depot door has been opened through the garage door control module. Then, after receiving the information that the depot door is in the bypass state and it is determined that the depot door has been opened, the interlock sends this information to the zone controller ZC, and then the zone controller ZC sends the depot door opening information and the information that the depot door is in the bypass state to the on-board ATP of the train. After receiving this information, the on-board ATP allows the train to leave the depot.

[0108] Through the garage door control module, the present invention can, when the garage door is in the bypass state and the garage door is closed, allow the user to remotely open the garage door and confirm that the garage door is open. After the interlock receives the information that the garage door is in the bypass state and determines that the garage door is open, it sends this information to the zone controller ZC, and then the zone controller ZC sends this information to the on-board ATP of the train. After receiving this information, the on-board ATP allows the train to leave the depot, effectively avoiding the safety hazards caused by the signal system defaulting that the garage door is open when the garage door is in the "bypass" state, and realizing the safety protection of the garage door by the system.

After receiving them, the on-vehicle ATP allows the train to perform static tests, dynamic tests, and enter and leave the depot, avoiding the safety hazards brought by the signal system defaulting that the library door is in the open state when the garage door is in the "bypass" state, and improving the safety of operations when the garage door is in the bypass state.

[0164] In one embodiment of the present invention, a train inspection depot and a car wash are usually configured in the vehicle depot / parking lot. For each track in the train inspection depot, a garage door is set, and a garage door is set at each end of the car wash. Under normal circumstances, the garage door control is in the automatic gear. According to the plan, the signal subsystem sends an opening command to the garage door. If the inspection conditions are met, the garage door opens, and the train can perform car washing, static tests, and dynamic tests. If the garage door fails to open within the specified time, an alarm will be given at the train operation control workstation, and then manual intervention will be carried out, which is divided into the following four situations:
