Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to a local control panel simulation device for controlling platform screen doors in subway underground stations. Background Technology

[0002] In subway operation, the platform screen door system is an important device to ensure passenger safety and train operation order. Its controller is usually installed on the platform or in the train control room and operated by the subway driver or control personnel. After the train arrives at the station and comes to a complete stop, the platform screen door will open or close synchronously with the train door.

[0003] However, when the platform screen doors malfunction, the driver must understand the situation and take action through the local control panel of the platform screen doors. But in actual training, due to safety and operational considerations, trainees cannot directly operate the actual local control panel of the platform screen doors. This results in insufficient training experience and difficulty in effectively mastering the emergency response procedures for the platform screen doors. There is a potential risk that operational delays or even passenger safety may be affected due to lack of proficiency in operation. Utility Model Content

[0004] The purpose of this invention is to provide a local control panel simulation device for controlling platform screen doors in underground subway stations, so as to solve at least one of the above-mentioned technical problems.

[0005] The technical problem solved by the utility model can be achieved by the following technical solutions:

[0006] A local control panel simulation device for controlling platform screen doors in subway underground stations includes a subway driving simulation device, which includes a simulated car door, a simulated platform screen door, and a simulated platform screen door frame, as well as a control logic judgment system and an alarm device.

[0007] The control logic judgment system includes a normally closed reflective optical proximity switch, which is installed on the simulated shielding door frame with its sensing direction facing the simulated car door. The simulated car door is provided with a reflective strip that cooperates with the normally closed reflective optical proximity switch.

[0008] When the simulated car door is closed, the reflective strip is located within the effective reflection area of ​​the normally closed reflective optical proximity switch;

[0009] The control logic judgment system also includes a normally open contact trigger switch, which is located on the simulated shielded door leaf and is triggered when the simulated shielded door leaf closes.

[0010] The normally closed reflective optical proximity switch and the normally open contact trigger switch form a series structure and are connected to the alarm device.

[0011] In the above design, when the simulated car door is open and the simulated shielding door is closed, the normally closed reflective optical proximity switch remains closed because it has no reflective strip in front of it, and the normally open contact trigger switch is closed by pressure when the shielding door is closed, which enables the control logic judgment system to conduct and triggers the alarm device to alarm, so as to prompt the operator to handle the fault situation. Through multiple fault practice, the operator can properly handle the fault situation in actual application.

[0012] In subway driving simulation equipment, PLC logic triggering is complex and has a heavy operating burden. In this patent application, deterministic logic triggering that does not require programming changes is removed from the PLC. This is to ensure the stability and reliability of operation, reduce the operating burden of the PLC, reduce the difficulty of PLC programming, and avoid uncertainty in deterministic logic triggering caused by PLC triggering errors or programming errors.

[0013] Preferably, the normally closed reflective optical proximity switch is mounted on the simulated shielding door frame via a universal adjustment bracket; a plastic protective cover is fixed on the universal adjustment bracket outside the normally closed reflective optical proximity switch, the plastic protective cover has a light-transmitting hole facing the simulated car door, and the surface of the plastic protective cover is coated with a light-absorbing coating.

[0014] Preferably, the simulated shielding door frame is provided with contacts that cooperate with a normally open contact trigger switch. When the simulated shielding door is closed, the normally open contact trigger switch contacts the contacts and closes.

[0015] Preferably, it also includes a metal chassis, which houses an industrial control computer and a power supply; the industrial control computer has a PLC interface, which adopts a push-pull self-locking connection structure, and the PLC interface is connected to the subway simulation driving simulation equipment via a cable; the power supply is electrically connected to the industrial control computer, the control logic judgment system, and the alarm device, and the power supply provides power to the above components.

[0016] Preferably, the sound-generating component of the alarm device is an integrated sound and light alarm, which is based on a miniature voice recording and playback chip and electrically connected to a piezoelectric ceramic buzzer and a speaker.

[0017] Preferably, the bottom of the metal chassis is detachably and fixedly connected to a base, and each of the four corners of the base is provided with a brakeable pulley.

[0018] Preferably, a wire tie rod is provided on the rear side of the metal chassis. The wire tie rod is horizontally placed and its two ends are fixedly connected to the outer wall of the metal chassis.

[0019] In summary, this utility model has the following beneficial effects:

[0020] By setting up a control logic judgment system and alarm device that works in conjunction with the subway simulation driving equipment, a safe and repeatedly practiced fault handling environment is created, enabling trainees to master fault identification and emergency handling skills for subway platform screen doors without affecting actual operations. This solves the problem of lack of fault experience in practical training for subway platform screen doors. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model will be further explained below with reference to specific illustrations.

[0027] refer to Figures 1 to 4 A local control panel simulation device for controlling platform screen doors in subway underground stations includes a subway driving simulation device, which includes a simulated car door 1, a simulated platform screen door 2, a simulated platform screen door frame 3, and also includes a control logic judgment system and an alarm device 8.

[0028] The control logic judgment system includes a normally closed reflective optical proximity switch, which is located on the simulated shielding door frame 3 and its sensing direction is towards the simulated car door 1. The simulated car door 1 is provided with a reflective strip that cooperates with the normally closed reflective optical proximity switch.

[0029] When the simulated car door 1 is closed, the reflective strip is located within the effective reflection area of ​​the normally closed reflective optical proximity switch.

[0030] The control logic judgment system also includes a normally open contact trigger switch, which is located on the simulated shielding door 2 and is triggered when the simulated shielding door 2 closes.

[0031] A normally closed reflective optical proximity switch and a normally open contact trigger switch are connected in series to the alarm device 8.

[0032] When the simulated car door 1 is open and the simulated shielding door 2 is closed, the normally closed reflective optical proximity switch remains closed because it has no reflective strip in front of it, and the normally open contact trigger switch is closed by pressure when the simulated shielding door 2 is closed, which enables the control logic judgment system to conduct and triggers the alarm device 8 to alarm, so as to prompt the operator to handle the fault situation. Through multiple fault practice, the operator can properly handle the fault situation in actual application.

[0033] In subway driving simulation equipment, PLC logic triggering is complex and has a heavy operating burden. In this patent application, deterministic logic triggering that does not require programming changes is removed from the PLC. This is to ensure the stability and reliability of operation, reduce the operating burden of the PLC, reduce the difficulty of PLC programming, and avoid uncertainty in deterministic logic triggering caused by PLC triggering errors or programming errors.

[0034] A normally closed reflective optical proximity switch is mounted on the simulated shielded door frame via a universal adjustment bracket. A plastic protective cover is fixed to the universal adjustment bracket, surrounding the normally closed reflective optical proximity switch. The plastic protective cover has a light-transmitting hole facing the simulated door 1, and its surface is coated with a light-absorbing coating. The universal adjustment bracket includes a spherical hinge and a locking nut for locking the spherical hinge, allowing for adjustment and fixation of the normally closed reflective optical proximity switch's rotation angle. The plastic protective cover provides protection and light shielding, preventing ambient light interference and physical impacts from affecting the operation of the normally closed reflective optical proximity switch.

[0035] The simulated shielding door 2 has contacts on its frame that cooperate with a normally open contact trigger switch. When the simulated shielding door 2 is closed, the normally open contact trigger switch contacts the contacts and closes.

[0036] It also includes a metal chassis 4, which houses an industrial control computer and a power supply. The industrial control computer has a PLC interface with a push-pull self-locking connection structure. The PLC interface is connected to the subway driving simulation equipment via a cable. The power supply is electrically connected to the industrial control computer, the control logic judgment system, and the alarm device 8, and supplies power to these components. The power supply specifically uses a 24V 18650mAh lithium battery. The push-pull self-locking connection structure of the PLC interface prevents the cable from becoming loose in a vibrating environment or due to accidental pulling, ensuring the reliability of the communication connection during training. The push-pull self-locking connection structure is an existing structure and will not be described in detail here.

[0037] The front of the metal chassis 4 is equipped with a control panel 5, which has buttons 6 and corresponding indicator lights 7 for triggering the opening and closing of the simulated car door 1, the opening and closing of the simulated shielding door 2, and the closing of the simulated shielding door 2, respectively; buttons 6 and indicator lights 7 are electrically connected to the industrial control computer.

[0038] Operators can clearly see the status of the simulated door 1 and the simulated platform screen door 2 by observing the indicator lights 7 on the control panel 5. They can manually control the opening and closing of the simulated door 1 and the simulated platform screen door 2 through the various buttons 6. This improves the realism of the training, enhances the efficiency and safety of the simulation training, and strengthens the operator's ability to handle malfunctions of the platform screen door and the simulated door 1.

[0039] The sound-generating component of the alarm device 8 is an integrated sound and light alarm, which is based on a miniature voice recording and playback chip and electrically connected to a piezoelectric ceramic buzzer and a speaker. The alarm device 8 is located on the control panel 5.

[0040] The metal chassis 4 has a detachable base 9 fixedly connected to its bottom, and each of the four corners of the base 9 is equipped with brakeable casters 10. This allows the metal chassis 4 to be moved to any subway simulation driving simulator that needs to be used.

[0041] A cable tie rod is located on the rear side of the metal chassis 4. The cable tie rod is horizontally positioned, and its two ends are fixedly connected to the outer wall of the metal chassis 4. Cables are secured to the cable tie rod with cable ties or Velcro, which not only neatly and secures the cables but also prevents them from tripping over operators, reducing safety hazards.

[0042] When in use, move the metal chassis 4 to the required subway driving simulation equipment, and connect the PLC interface on the industrial control computer to the subway driving simulation equipment through a cable to enable communication between the industrial control computer and the PLC controller of the subway driving simulation equipment, and turn on the power.

[0043] The control panel 5 is equipped with buttons 6 and corresponding indicator lights 7 for triggering the opening and closing of the simulated vehicle door 1, the opening and closing of the simulated platform door 2, and the closing of the simulated platform door 2. It is also equipped with buttons for triggering operation permission switch and interlock release switch, as well as front operation permission indicator lights, middle operation permission indicator lights, and rear operation permission indicator lights. All the above indicator lights and buttons are connected to the industrial control computer.

[0044] The operation permission switch is a key-operated rotary switch. When the operator inserts the corresponding key and rotates the operation permission switch from the automatic position to the manual position, at least one of the operation permission indicator lights at the front, middle, and rear of the vehicle will light up, indicating that the equipment is in an activated state. When the operator rotates the operation permission switch from the manual position to the automatic position, the operation permission indicator lights at the front, middle, and rear of the vehicle will turn off, indicating that the equipment is in an inactive state.

[0045] During the door opening simulation, the operator presses button 6 to trigger the opening of simulated vehicle door 1 and simulated shielding door 2. After receiving the signal, the industrial control computer controls the opening of simulated vehicle door 1 and simulated shielding door 2, and the corresponding indicator light 7 lights up. The normally closed reflective optical proximity switch remains closed because it has no reflective strip in front of it, and the normally open contact trigger switch remains open because the simulated shielding door 2 is open. The control logic judgment system is not conducting, and the alarm device 8 does not sound.

[0046] When the door closing simulation is performed, the operator presses button 6 to trigger the closing of simulated door 1 and simulated shielding door 2. After receiving the signal, the industrial control computer controls the closing of simulated door 1 and simulated shielding door 2, and the corresponding indicator light 7 lights up. The normally closed reflective optical proximity switch is disconnected because of the reflective strip in front of it, and the normally open contact trigger switch is closed by pressure because the simulated shielding door 2 is opened. The control logic judgment system is not conducting, and the alarm device 8 does not sound.

[0047] When a fault occurs where simulated door 1 is closed and simulated shielding door 2 is open, the normally closed reflective optical proximity switch remains closed because it has no reflective strip in front of it, and the normally open contact trigger switch is closed due to pressure caused by the simulated shielding door 2 being closed. The control logic judgment system is activated, and the alarm device 8 sounds an alarm, prompting the operator to handle the fault.

[0048] The foregoing has shown and described the basic principles and main features of the utility model, as well as its advantages. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the utility model. Various changes and modifications can be made to the utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
