Description

Technical Field

[0001] This invention relates to train signal control systems, and more particularly to an intelligent control system, method, device, and medium for platform screen doors. Background Technology

[0002] Platform screen doors (PSM) are installed at the edge of subway platforms to separate trains from the waiting area. They open and close automatically when trains arrive and depart, creating a safe and comfortable waiting environment for passengers. PSM systems are widely used both domestically and internationally as a safety barrier for passengers waiting on platforms.

[0003] The platform screen door system has a local control box (LCB) above each individual door, allowing staff to control the opening and closing of the doors. Under the current design, if the platform screen door is opened or closed via the LCB, it will exit the safety circuit, displaying a closed and locked indicator, allowing trains to enter and exit the station normally. However, in emergency situations, such as when a person or object is trapped in the platform screen door, if staff mistakenly operate the LCB manually to open or close it, trains could continue to enter and exit the station, potentially causing a very serious safety accident.

[0004] A search of Chinese Patent Publication No. CN115306252A reveals an automatic alignment and isolation system and method for platform screen doors based on online detection. Specifically, it discloses a system including a central controller, a door operator controller (DCU), a drive motor, a local control box (LCB), an electromagnetic lock, a door sensor, a signal system, and a door system. The central controller embeds alignment and isolation software modules that communicate with both the signal system and the door operator controller (DCU). The door operator controller (DCU) is connected to the drive motor, the local control box (LCB), the electromagnetic lock, and the door sensor. The signal system and the door system are communicatively connected. However, this existing patent cannot prevent serious safety accidents caused by misoperation. Therefore, how to achieve effective platform screen door control to avoid serious safety accidents caused by misoperation has become a technical problem that needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art and provide an intelligent control system, method, device and medium for platform screen doors.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] According to a first aspect of the present invention, an intelligent control system for platform screen doors is provided, the system comprising:

[0008] The safety circuit includes an authorized relay node and a manual on / off switch connected in series. When the authorized relay node and the manual on / off switch are simultaneously turned on, the safety circuit is activated.

[0009] The authorization relay coil is connected to the authorization relay node of the safety circuit. When the authorization relay coil is energized, it causes the authorization relay node to be turned on.

[0010] As a preferred technical solution, a non-self-resetting button is provided in the excitation circuit of the authorization enable relay coil. The authorization enable relay coil will only be activated when the non-self-resetting button is pressed.

[0011] As a preferred technical solution, the non-self-resetting button is located on the IBP panel in the vehicle control room and is controlled by personnel in the vehicle control room.

[0012] As a preferred technical solution, the system also includes an authorization indicator light located next to the non-self-resetting button, which is driven by a logic driver.

[0013] As a preferred technical solution, the logic driver acquires the authorization enable relay coil and the manual on / off state, and drives the authorization enable indicator light according to the logic operation result.

[0014] As a preferred technical solution, the result of the logical operation is as follows:

[0015] When the local control box LCB is switched to manual on / off, the authorization permission relay coil is not activated, and the authorization permission indicator light flashes.

[0016] When the local control box LCB is switched to manual on / off, the authorization enable relay coil is energized, and the authorization enable indicator light remains on.

[0017] When the local control box LCB is in automatic mode, the authorization enable relay coil is energized, and the authorization enable indicator light flashes.

[0018] When the local control box (LCB) is in automatic mode, the authorization relay coil is not energized, and the authorization indicator light is off.

[0019] As a preferred technical solution, the system also includes a camera installed above the platform screen door. When the platform screen door is manually operated, the system is activated to upload the video information of the platform screen door to the control room in real time.

[0020] According to a second aspect of the present invention, a method for employing the aforementioned intelligent control system for platform screen doors is provided, the method comprising the following steps:

[0021] Step S1: Perform manual door opening / closing operation;

[0022] Step S2: The logic driver drives the authorization light to flash based on the collected manual door opening and closing information.

[0023] Step S3: Link the camera of the corresponding platform door to push video messages in real time;

[0024] Step S4: Based on the video information, select whether to authorize permission. If yes, proceed to step S6; otherwise, proceed to step S5.

[0025] In step S5, when the option to not authorize is selected, the platform door performs the opening / closing operation, but the safety circuit is not connected, and trains cannot enter or leave the station at this time.

[0026] In step S6, when authorization is granted, the platform door performs an opening / closing operation, the safety circuit is activated, and trains can enter and exit the station normally.

[0027] As a preferred technical solution, in step S1, the door is opened / closed manually by the operator at the local control box (LCB).

[0028] As a preferred technical solution, in step S4, the control room operator selects whether to authorize permission based on the video information.

[0029] According to a third aspect of the present invention, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the program to implement the method described thereon.

[0030] According to a fourth aspect of the present invention, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method described thereon.

[0031] Compared with the prior art, the present invention has the following advantages:

[0032] 1. This invention can effectively control the opening / closing of platform doors in case of accidental operation, thus avoiding serious accidents caused by misoperation.

[0033] 2. The present invention changes the manual control method for opening / closing a single platform door from being uncontrolled by the safety circuit to two modes: controlled by the safety circuit and uncontrolled by the safety circuit. This makes it more flexible and adaptable to more different operational needs.

[0034] 3. The logic-driven controller of this invention can intelligently drive the lamp position display and provide intelligent indication information to the operator.

[0035] 4. This invention can realize the linkage between platform screen doors and video. When the platform screen doors malfunction or are manually operated, the camera will be linked in real time, so that the control room personnel can keep abreast of the actual situation on site.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0043] This invention provides an intelligent control system for platform screen doors (LCBs) to solve serious operational accidents caused by human error in operating the LCBs.

[0044] This invention modifies the safety circuit design of existing platform screen door systems, such as... Figure 6 As shown, there is an LCB local control box with four positions. In automatic mode, the DCU determines whether the platform door is closed and locked. When the door is manually opened or closed, the safety circuit is activated, indicating that it is closed and locked. Figure 5 As shown.

[0045] like Figure 1 As shown, this invention incorporates an authorization relay node in series in the safety circuit of each platform screen door. The safety circuit can only be activated when both the authorization relay and the manual open / close button are simultaneously activated. This effectively prevents accidental manual opening / closing operations on the LCB from directly activating the safety circuit.

[0046] like Figure 2 As shown, the present invention implements an authorization and permission circuit design, which sets up an authorization and permission relay coil. When the authorization and permission relay coil is energized, it will drive all authorization and permission relay nodes to be turned on.

[0047] In the excitation circuit of the authorization relay coil, a non-self-resetting button is installed. The authorization relay will only be activated when the button is pressed. The button can be located on the IBP panel in the vehicle control room (the location can be changed as needed) and controlled by personnel in the vehicle control room to achieve dual-person verification of the safety circuit conduction.

[0048] like Figure 3 As shown, the present invention incorporates an authorization indicator light design. An authorization indicator light is added next to the authorization button, and this light is driven by a logic driver.

[0049] The logic driver acquires the status of the LCB manual on / off knob and the status of the authorized relay.

[0050] The authorization indicator light is driven based on the result of the logical operation, as follows:

[0051] When the LCB is switched to manual on / off mode, the authorization relay is not activated, and the indicator flashes.

[0052] When the LCB is switched to manual on / off mode, the authorization relay is activated, and the indicator light remains on.

[0053] When LCB is in automatic mode, the authorization relay is activated, and the light flashes.

[0054] When the LCB is in automatic mode, if the authorization relay is not activated, the lamp will be off.

[0055] The authorization allows different indicator lights to display different prompts for the operator.

[0056] The invention also incorporates a linkage function design, which involves installing a camera above the platform screen door. When the platform screen door is manually operated, the camera is linked to upload the video information of that door to the control room in real time to assist the operator in making a judgment.

[0057] The above is an introduction to the system embodiments. The following method embodiments will further illustrate the solution of the present invention.

[0058] like Figure 4 As shown, the intelligent control method of the present invention includes the following steps:

[0059] Step 1: Manually open / close the door on the LCB box.

[0060] Step 2: The logic driver drives the authorization light to flash based on the collected manual door opening and closing information.

[0061] Step 3: The system links with the platform door camera to push video messages in real time.

[0062] Step 4: The control room operator, based on the video information, selects whether to authorize permission.

[0063] Step 5: When the control room operator selects not to authorize, the platform door will perform the opening / closing operation, but the safety circuit will not be connected, and the train cannot enter or leave the station.

[0064] Step 6: When the operator in the control room selects authorization permission, the platform door will perform the opening / closing operation, the safety circuit will be activated, and the train can enter and exit the station normally.

[0065] This invention changes the manual control method for opening / closing a single platform door from being uncontrolled by the safety circuit to having two modes: controlled by the safety circuit and uncontrolled by the safety circuit. This makes it more flexible and adaptable to more different operational needs.
