Description

Technical Field

[0001] This invention relates to the field of pit-type parking garage technology, and in particular to a pedestrian and vehicle fall prevention system and method based on a pit-type intelligent three-dimensional parking garage. Background Technology

[0002] With the widespread application of intelligent automated parking systems, more and more different types of intelligent automated parking systems have been developed. Underground intelligent automated parking systems, located below ground level, are one such type. These systems typically use elevator shafts to move vehicles to their respective parking levels. However, the construction pit within these pits has become a significant safety hazard, with incidents of vehicles plunging into them being commonplace, potentially causing injuries or fatalities. Therefore, there is an urgent need to develop a fall protection system and method to improve the safety performance of parking systems. Summary of the Invention

[0003] The purpose of this invention is to propose a vehicle and pedestrian fall prevention system and method based on a pit-type intelligent three-dimensional parking garage, which solves the problem of vehicles accidentally falling into the building foundation pit in the prior art.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A pedestrian and vehicle fall prevention system based on a pit-type intelligent three-dimensional parking garage includes a building pit, a lift frame, a lift, a parking hall platform sealing plate, a fall prevention protection platform, and guide wheel seats;

[0006] The elevator frame is installed inside the building foundation pit, the elevator is movable up and down and installed on the elevator frame, and the hall platform sealing plate is installed at the pit opening of the building foundation pit;

[0007] The guide wheel seat is installed on the inner wall of the building foundation pit. The fall protection platform includes a fall protection frame and a column. One end of the column is connected to the fall protection frame, and the other end of the column is slidably installed on the guide wheel seat. The bottom of the other end of the column can abut against the elevator.

[0008] Furthermore, the fall protection platform also includes a connecting frame, which has a first waist-shaped hole and a second waist-shaped hole. The column can be detachably installed in the first waist-shaped hole, and the fall protection frame can be detachably installed in the second waist-shaped hole.

[0009] Specifically, the fall protection platform also includes a blocking component and a buffer pad. The blocking component is installed on the column, and the buffer pad is installed on the bottom surface of the blocking component. The bottom surface of the buffer pad can abut against the top surface of the guide wheel seat.

[0010] Preferably, it also includes a parking hall located above the building foundation pit, the parking hall having an entrance, and the top surface of the fall arrestor frame being higher than the ground level of the entrance.

[0011] In some embodiments, the fall protection platform further includes a fall arrestor installed on the fall protection frame, the fall arrestor being used to cover the open area of ​​the fall protection frame.

[0012] Furthermore, the guide wheel seat includes a fixed seat, a mounting block, a guide wheel, an adjusting component, and a locking component;

[0013] The guide wheel is rotatably mounted on the mounting block and abuts against the column. The adjusting member is mounted on the fixed base and its end abuts against the mounting block. The locking member is mounted on the fixed base and its end is connected to the mounting block.

[0014] Specifically, it also includes a wheel seat support assembly, which is located below the vehicle hall platform sealing plate. One end of the wheel seat support assembly is installed on the inner wall of the building foundation pit, and the other end of the wheel seat support assembly is equipped with the guide wheel seat.

[0015] Preferably, the wheel seat support assembly includes a mounting strip, a connecting strip, and a mounting component;

[0016] The two ends of the connecting strip are respectively connected to the mounting strip, one end of each of the two mounting strips is respectively equipped with the mounting component, and the other end of the two mounting strips is equipped with the same guide wheel seat. The mounting component is installed on the inner wall of the building foundation pit.

[0017] In some embodiments, the elevator is provided with a support member located below the guide wheel seat, and the top surface of the support member can abut against the bottom surface of the column;

[0018] It also includes a power-off switch and a contact rod. The entrance is equipped with a first lifting door. The power-off switch is installed on the inner wall of the building foundation pit and is electrically connected to the first lifting door. The contact rod is installed on the support member and can contact the power-off switch.

[0019] A method for preventing pedestrian and vehicle falls based on a pit-type intelligent automated parking garage includes the following steps:

[0020] Step 1: When parking, the user drives the car into the range of the ground induction coil at the entrance. The ground induction coil at the entrance detects the car and sends a signal to the PLC. If the touch bar contacts the power-off switch, the first lifting door at the entrance will be controlled. If the touch bar does not contact the power-off switch, the first lifting door at the entrance cannot be controlled to open.

[0021] Step 2: After the first elevator door at the entrance opens, the user drives the car into the elevator inside the building foundation pit. The building foundation pit is equipped with a detection device, which is used to detect information such as the length, height and whether the wheels are in place of the vehicle.

[0022] Step 3: After the car is parked within the designated area, the user gets out of the car and leaves the parking hall, and performs the parking operation on the LCD screen at the entrance. After confirming the vehicle information, the PLC receives the signal feedback and controls the first lifting door to close.

[0023] Step 4: The elevator begins to descend, and the fall protection platform also descends synchronously until the column separates from the elevator. After the fall protection frame covers the foundation pit, the trolley moves the car to the corresponding parking space after the elevator has descended to the correct position. Then the elevator rises back to the position for the next round of parking.

[0024] Step 5: When retrieving the vehicle, the user performs the vehicle retrieval operation on the LCD screen at the entrance. After confirming the vehicle information, the elevator begins to descend, and the fall protection platform also descends synchronously until the column separates from the elevator. The fall protection frame covers the foundation pit of the building. After the elevator descends to the set position, the transport trolley moves the car to the elevator, and then the elevator rises. During this process, the elevator gradually lifts the fall protection platform. When the contact bar and the power-off switch are not in contact, neither the first elevator door at the entrance nor the second elevator door at the exit can be opened.

[0025] Step 6: After the elevator rises to the correct position and the contact bar contacts the power-off switch, the second exit door opens. The user gets into the car and drives away. The ground sensor at the exit detects the car leaving and sends a feedback signal, closing the second exit door.

[0026] Compared with the prior art, one of the above technical solutions has the following beneficial effects:

[0027] 1. By using the elevator, fall protection platform, and vehicle platform sealing plate, the fall protection platform descends synchronously with the elevator during descent. This not only eliminates the need for additional drive to control the fall protection platform, reducing production costs, but also allows the bottom of the fall protection frame to slowly abut against the top of the guide wheel seat, preventing the fall protection frame from impacting the guide wheel seat with greater gravitational potential energy during free fall, thus avoiding damage to the fall protection frame and guide wheel seat, thereby improving the service life of the personnel and vehicle fall protection system.

[0028] 2. With the fall protection platform, when the fall protection platform is blocked by the guide wheel seat, the fall protection frame covers the pit opening formed after the elevator descends, thereby preventing other cars from entering the pit opening of the building foundation and causing safety accidents.

[0029] 3. By installing four guide wheel seats at the four corners of the building foundation pit, the fall arrestor frame is installed stably. Even if a car runs into the pit, the fall arrestor frame can support the car well, stabilize the car's center of gravity, and prevent it from overturning, thus improving the safety performance of the people and vehicle fall arrestor system.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0043] In one embodiment of the present invention, such as Figure 1-10As shown, a vehicle and pedestrian fall prevention system based on a pit-type intelligent automated parking garage includes a building pit 1, a lift frame 2, a lift 3, a parking platform sealing plate 4, a fall prevention protection platform 5, and guide wheel seats 6. The lift frame 2 is installed inside the building pit 1, the lift 3 is vertically movable and installed on the lift frame 2, and the parking platform sealing plate 4 is installed at the pit opening of the building pit 1. The guide wheel seats 6 are installed on the inner wall of the building pit 1. The fall prevention protection platform 5 includes a fall prevention frame 51 and a column 52. One end of the column 52 is connected to the fall prevention frame 51, and the other end of the column 52 is slidably installed on the guide wheel seats 6, and the bottom of the other end of the column 52 can abut against the lift 3. In this embodiment, the top surface of the guide wheel seat 6 is flush with the top surface of the parking platform sealing plate 4, and the top surface of the parking platform sealing plate 4 is flush with the top surface of the elevator 3. During operation, the elevator 3 rises to its highest point, that is, to the top of the elevator frame 2. At this time, the top surface of the elevator 3 is flush with the top surface of the parking platform sealing plate 4. The bottom of the column 52 rests against the elevator 3. The fall arrestor 51 is erected above the parking platform sealing plate 4 via the column 52. Then, the user drives the car onto the top surface of the elevator 3. At this time, the car is located between the fall arrestor 51 and the elevator 3. After the user parks the car, the user gets out of the car and stands on the parking platform sealing plate 4. After the user leaves the parking hall 9, the elevator 3 descends, and the fall arrestor 5 also descends synchronously. The elevator 3 has a frequency conversion mode. Through the frequency conversion mode, the speed of the elevator 3 is adjusted. Starting from zero, the elevator accelerates and descends at the same speed as the fall arrestor platform 5. After descending a certain distance, the bottom of the column 52 separates from the elevator 3. At this time, the bottom of the fall arrestor frame 51 abuts against the top surface of the guide wheel seat 6, covering the pit opening formed after the elevator 3 descends. Then, the elevator 3 accelerates its descent. When the elevator 3 descends to near the set position, it decelerates until it stops smoothly at the set position. A transport trolley is provided on one side of the building pit 1. The transport trolley transports the car parked on the elevator 3 to the underground garage. Finally, the elevator 3 rises. During the ascent, the elevator 3 contacts the bottom of the column 52, thereby lifting the column 52 until the elevator 3 rises to the highest point of the elevator frame 2. At this time, the fall arrestor frame 51 returns to its original position.This application utilizes the elevator 3, the fall protection platform 5, and the vehicle platform sealing plate 4. During descent, the fall protection platform 5 descends synchronously with the elevator 3. This eliminates the need for additional drive to control the fall protection platform 5, reducing production costs. Furthermore, it allows the bottom of the fall protection frame 51 to slowly abut against the top of the guide wheel seat 6, preventing the fall protection frame 51 from impacting the guide wheel seat 6 with significant gravitational potential energy during free fall, thus preventing damage to both the fall protection frame 51 and the guide wheel seat 6 and extending the service life of the vehicle and passenger fall protection system. Further, when the fall protection... With the fall protection platform 5 blocked by the guide wheel seats 6, the fall protection frame 51 covers the pit opening formed after the elevator 3 descends, thereby preventing other vehicles from entering the pit opening of the building foundation pit 1 and causing safety accidents. Preferably, there are four columns 52 and four guide wheel seats 6, which are installed at the four corners of the building foundation pit 1, thus making the fall protection frame 51 stable. Even if a vehicle enters, the fall protection frame 51 can support the vehicle well, stabilize the vehicle's center of gravity, and prevent overturning, thereby improving the safety performance of the vehicle and personnel fall protection system.

[0044] like Figure 4-7 As shown, the fall protection platform 5 also includes a connecting frame 53, which has a first waist-shaped hole 531 and a second waist-shaped hole 532. The column 52 is detachably installed in the first waist-shaped hole 531, and the fall protection frame 51 is detachably installed in the second waist-shaped hole 532. In this embodiment, the column 52 is detachably installed in the first waist-shaped hole 531 of the connecting frame 53, and the fall arrestor 51 is detachably installed in the second waist-shaped hole 532. Specifically, a bolt-assembled connection structure is adopted, so that the end of the column 52 can move along the length direction of the first waist-shaped hole 531, thereby adjusting the verticality of the column 52 after installation and preventing the column 52 from sliding in the guide wheel seat 6 in a figure-eight shape. Moreover, a large error tolerance is allowed in the processing and installation steps, which greatly reduces the installation difficulty and achieves the effect of improving the structural reliability and installation efficiency of the personnel and vehicle fall arrestor system. Furthermore, both the fall arrestor 51 and the column 52 are detachably installed in the connecting frame 53, which facilitates processing, painting and transportation, and allows for independent size adjustment and gap adjustment.

[0045] like Figure 4-7As shown, the fall protection platform 5 also includes a blocking member 54 and a buffer pad 55. The blocking member 54 is installed on the column 52, and the buffer pad 55 is installed on the bottom surface of the blocking member 54. The bottom surface of the buffer pad 55 can abut against the top surface of the guide wheel seat 6. In this embodiment, each column 52 is respectively equipped with the blocking member 54 and the buffer pad 55. When the fall protection platform 5 descends, specifically, the column 52 slides within the guide wheel seat 6 until the guide wheel seat 6 abuts against the blocking member 54. The buffer pad 55 is installed on the bottom surface of the blocking member 54, which helps to reduce the noise generated when the guide wheel seat 6 contacts the blocking member 54.

[0046] like Figure 1 As shown, the system also includes a parking hall 9, located above the building foundation pit 1. The parking hall 9 has an entrance 91, and the top surface of the fall arrestor frame 51 is higher than the ground level of the entrance 91. In this embodiment, when the blocking member 54 abuts against the guide wheel seat 6, the fall arrestor frame 51 is higher than the ground level of the entrance 91. Specifically, the distance between the top surface of the fall arrestor frame 51 and the ground level of the entrance 91 is 200mm. By setting the top surface of the fall arrestor frame 51 higher than the ground level of the entrance 91, the fall arrestor frame 51 has a blocking function, thereby preventing other vehicles from entering the building foundation pit 1 and causing safety accidents, thus improving the safety performance of the vehicle and pedestrian fall arrestor system.

[0047] like Figure 8 As shown, the fall protection platform 5 also includes a fall protection component 56, which is installed on the fall protection frame 51 and is used to cover the hollow area of ​​the fall protection frame 51. In this embodiment, the fall protection component 56 can be a cover plate or a pull plate mesh. The cover plate is installed on the top surface of the fall protection frame 51, thereby covering the hollow area of ​​the fall protection frame 51. It should be noted that the fall protection frame 51 is a hollow frame, and its main function is to prevent vehicles from falling. Therefore, the cover plate is set to cover the screw hole area of ​​the fall protection frame 51, thereby preventing people from falling. Preferably, the pull plate mesh is used, as its mesh structure is translucent and will not affect the lighting in the building foundation pit 1, thereby improving the safety performance of the personnel and vehicle fall protection system.

[0048] like Figure 3As shown, the guide wheel seat 6 includes a fixed seat 61, a mounting block 62, a guide wheel 63, an adjusting member 64, and a locking member 65; the guide wheel 63 is rotatably mounted on the mounting block 62 and can abut against the column 52; the adjusting member 64 is mounted on the fixed seat 61 and its end abuts against the mounting block 62; the locking member 65 is mounted on the fixed seat 61 and its end is connected to the mounting block 62. In this embodiment, the column 52 is a square column, and the number of mounting blocks 62 and guide wheels 63 is eight. Four mounting blocks 62 and four guide wheels 63 form a layer, that is, each side of the column 52 has two guide wheels 63 abutting against each other. Each mounting block 62 is equipped with one adjusting member 64 and two locking members 65. The adjusting member 64 is an adjusting bolt, and the locking member 65 is a locking bolt. When the column 52 slides in the guide wheel seat 6, specifically, the column 52 passes through the... The fixed base 61 is provided, and the column 52 abuts against the guide wheel 63, and the guide wheel 63 is driven to rotate by friction. Through the rolling friction structure, not only can wear be reduced and service life increased, but also noiseless operation and smooth movement of the column 52 can be improved. Furthermore, the adjusting member 64 is rotated to move the mounting block 62, thereby adjusting the gap between the guide wheel 63 and the column 52 or adjusting the verticality of the column 52. Finally, the locking member 65 is rotated to lock and fix the mounting block 62.

[0049] like Figure 9 As shown, it also includes a wheel seat support assembly 7, which is located below the vehicle platform sealing plate 4. One end of the wheel seat support assembly 7 is installed on the inner wall of the building foundation pit 1, and the other end of the wheel seat support assembly 7 is installed with the guide wheel seat 6. In this embodiment, there are four wheel seat support assemblies 7. The guide wheel seats 6 are installed on the inner wall of the building foundation pit 1 through the wheel seat support assemblies 7, which helps to improve the installation stability of the guide wheel seats 6.

[0050] like Figure 9-10 As shown, the wheel seat support assembly 7 includes mounting strips 71, connecting strips 72, and mounting members 73. The two ends of the connecting strips 72 are respectively connected to the mounting strips 71. The mounting members 73 are respectively mounted on one end of each of the two mounting strips 71, and the same guide wheel seat 6 is mounted on the other end of each of the two mounting strips 71. The mounting members 73 are installed on the inner wall of the building foundation pit 1. In this embodiment, the two mounting strips 71 and the connecting strips 72 form an H-shaped installation structure. This structure helps improve the structural stability of the wheel seat support assembly 7, making the guide wheel seat 6 firmly installed and less prone to loosening.

[0051] like Figure 1-2 and Figure 9As shown, the elevator 3 is equipped with a support member 31, which is located below the guide wheel seat 6. The top surface of the support member 31 can abut against the bottom surface of the column 52. It also includes a power-off switch 81 and a contact rod 82. The entrance 91 is equipped with a first lifting door. The power-off switch 81 is installed on the inner wall of the building pit 1 and is electrically connected to the first lifting door. The contact rod 82 is installed on the support member 31 and can contact the power-off switch. In this embodiment, there are four support members 31. Because the guide wheel seat 6 is located on the outside of the elevator 3, two support members 31 are provided on each side of the elevator 3, so that the column 52 can abut against the support member 31. In this embodiment, when the elevator 3 is at the highest point of the elevator frame 2, i.e., no car enters the building pit 1, the power-off switch 81 contacts the contact bar 82. At this time, the first lifting door of the entrance 91 is in a controllable state. However, when the elevator 3 is not at the highest point of the elevator frame 2, the power-off switch 81 does not contact the contact bar 82. At this time, the first lifting door of the entrance 91 is in a closed state and cannot be controlled, i.e., the first lifting door cannot be opened. This can prevent cars from entering the building pit 1 and improve the safety performance of the vehicle and personnel fall prevention system.

[0052] like Figure 1-10As shown, a method for a vehicle and pedestrian fall prevention system based on a pit-type intelligent automated parking garage includes the following steps: Step 1: When parking, the user drives the car into the range of the ground induction coil of entrance 91. The ground induction coil of entrance 91 detects the car and sends a signal to the PLC. If the contact rod 82 contacts the power-off switch 81, the first lifting door of entrance 91 is controlled. If the contact rod 82 does not contact the power-off switch 81, the first lifting door of entrance 91 cannot be controlled to open; Step 2: After the first lifting door of entrance 91 opens, the user drives the car into the elevator 3 in the building pit 1. The building pit 1 is equipped with a detection device, which is used to detect information such as the length, height, and whether the wheels are in place; Step 3: After the car is parked within the set area, the user gets out of the car and leaves the parking hall 9, and performs the parking operation on the LCD screen at the door. After confirming the vehicle information, the PLC receives the signal feedback and controls the first lifting door to close. Step 4: The elevator 3 begins to descend, and the fall protection platform 5 also descends synchronously until the column 52 separates from the elevator 3. After the fall protection frame 51 covers the pit of the building foundation pit 1, the elevator 3 descends to the designated position, and the trolley moves the car to the corresponding parking space. Then the elevator rises back to the position for the next round of parking. Step 5: When retrieving the car, the user performs the retrieval operation on the LCD screen at the door. After confirming the vehicle information, the elevator 3 begins to descend, and the fall protection platform 5 also descends synchronously until the column 52 separates from the elevator 3. After the fall protection frame 51 covers the pit of the building foundation pit 1, the elevator 3 descends to the set position, and the trolley moves the car to the elevator 3. Then the elevator 3 rises. During this process, the elevator 3 gradually lifts the fall protection platform 5. When the contact bar 82 and the power cut-off switch 81 are not in contact, the first elevator door of the entrance 91 and the second elevator door of the exit 92 cannot be opened.Step 6: After the elevator 3 rises to its designated position and the contact rod 82 contacts the power-off switch 81, the second elevator door of exit 92 opens. The user gets in and drives away. The ground sensor at exit 92 detects the car leaving and sends a feedback signal, closing the second elevator door of exit 92. In this embodiment, the power-off switch 81 is electrically connected to both the first and second elevator doors. When parking, the user drives the car into the ground sensor at entrance 91. The ground sensor at entrance 91 detects the car and sends a signal to the PLC. If the elevator 3 is at the top of the elevator frame 2 (i.e., the contact rod 82 contacts the power-off switch 81), the first elevator door of entrance 91 opens. If the elevator 3 is not at the top of the elevator frame 2 (i.e., the contact rod 82 contacts the power-off switch 81), the first elevator door of entrance 91 does not open, thus preventing the vehicle from falling into the pit. After the first elevator door of entrance 91 opens, the user drives the car onto the top surface of the elevator 3. The detection device inside the construction pit 1 detects the length, height, and wheel position of the vehicle. If the vehicle is too long or too tall, an alarm is triggered, and the user is guided out of the construction pit 1 using a screen. If the wheels are not parked correctly, the user is guided to park again using a screen. After the user parks the vehicle correctly, they turn off the engine, close the rearview mirrors, get out of the car, and leave the parking hall 9. Then, the user goes to the LCD screen at the entrance to confirm the vehicle information. After confirming the license plate, engine off status, door closed status, and rearview mirror closed status, the user clicks the "Confirm Parking" button. Upon receiving the signal, the PLC closes the first lifting door at entrance 91, and then the elevator 3 begins to descend. The fall arrestor platform 5 also descends synchronously until the upright 52 separates from the elevator 3. The fall arrestor frame 51 covers the pit opening, and the contact bar 82 and the power cut-off switch 81 are not in contact. Neither the first nor the second elevator door can be opened, preventing vehicles from falling into the pit and greatly improving parking safety. After the upright 52 separates from the elevator 3, the elevator 3 begins to accelerate downwards. Once the elevator 3 is ready to descend to the set position, it begins to decelerate, bringing it to a smooth stop. The trolley then moves the car to an empty parking space, and the elevator 3 rises back to its initial position for the next round of parking. When retrieving the car, the user performs the retrieval operation on the LCD screen at the entrance. After the user confirms the vehicle information and clicks "Confirm Vehicle Pickup", the PLC receives the signal and the elevator 3 begins to descend. During the descent, the contact bar 82 does not contact the power-off switch 81, and neither the first nor the second elevator door can be opened. After the elevator 3 descends to the set position, the transport trolley moves the car onto the elevator 3, and then the elevator 3 lifts the car up. During the ascent, the elevator 3 lifts the fall protection platform and makes the contact bar 82 contact the power-off switch 81, opening the second elevator door of the exit 92. The user enters the building pit 1 and gets into the car. After the user drives the car past the ground sensor at the exit 92, the PLC receives the signal and the second elevator door of the exit 92 closes.This method, through the contact bar 82 and the power-off switch 81, prevents the first and second lifting doors from opening during the movement of the elevator 3, thus preventing vehicles from entering. It should be noted that even maintenance personnel cannot open them after the power is cut off. Furthermore, if the first and second lifting doors malfunction and cannot close, the fall protection platform 5 can prevent vehicles from falling into the pit. Additionally, the detection device monitors the height, length, and wheel positioning of the vehicles, further preventing accidents. Moreover, the variable frequency elevator improves vehicle storage and retrieval efficiency, thereby enhancing the safety performance and storage efficiency of the vehicle and pedestrian fall prevention system based on the pit-type intelligent automated parking garage.

A method for using a pedestrian and vehicle fall prevention system based on a pit-type intelligent automated parking garage as described in any one of claims 1-6, characterized in that, Includes the following steps: Step 1: When parking, the user drives the car into the range of the ground induction coil at the entrance. The ground induction coil at the entrance detects the car and sends a signal to the PLC. If the touch bar contacts the power-off switch, the first lifting door at the entrance will be controlled. If the touch bar does not contact the power-off switch, the first lifting door at the entrance cannot be controlled to open. Step 2: After the first elevator door at the entrance opens, the user drives the car into the elevator inside the building foundation pit. The building foundation pit is equipped with a detection device, which is used to detect the length, height and whether the wheels are in place of the vehicle. Step 3: After the car is parked within the designated area, the user gets out of the car and leaves the parking hall, and performs the parking operation on the LCD screen at the entrance. After confirming the vehicle information, the PLC receives the signal feedback and controls the first lifting door to close. Step 4: The elevator begins to descend, and the fall protection platform also descends synchronously until the column separates from the elevator. After the fall protection frame covers the foundation pit, the trolley moves the car to the corresponding parking space after the elevator has descended to the correct position. Then the elevator rises back to the position for the next round of parking. Step 5: When retrieving the vehicle, the user performs the vehicle retrieval operation on the LCD screen at the entrance. After confirming the vehicle information, the elevator begins to descend, and the fall protection platform also descends synchronously until the column separates from the elevator. After the fall protection frame covers the foundation pit, the elevator descends to the set position, and the transport trolley moves the car onto the elevator. Then the elevator rises. During this process, the elevator gradually lifts the fall protection platform. When the contact bar and the power-off switch are not in contact, neither the first elevator door at the entrance nor the second elevator door at the exit can be opened. Step 6: After the elevator rises to the correct position and the contact bar contacts the power-off switch, the second exit door opens. The user gets into the car and drives away. The ground sensor at the exit detects the car leaving and sends a feedback signal, closing the second exit door.
