[0001] The present application relates to the field of elevator technology, and in particular to an elevator control method, system, intelligent terminal and storage medium. Background Art

[0002] An elevator is a device used to transport people or goods vertically in multi-story buildings. It achieves transportation between floors by moving one or more cabins up and down in a shaft.

[0003] In the related art, a safety system is usually configured in the control system of the elevator. When the control power of the elevator is cut off, the safety system will start, thereby activating the brake, which will fix the elevator car on the guide rail to prevent it from falling freely.

[0004] With regard to the above-mentioned related technologies, when the brake fixes the elevator car on the guide rail, the people in the car usually feel anxious because they are in an unsafe environment, and thus try to force open the car door or climb out of the car, which can easily cause the people in the car to fall from the car, resulting in low safety of the elevator control system, and there is still room for improvement. Summary of the invention

[0005] In order to improve the safety of an elevator control system, the present application provides an elevator control method, system, intelligent terminal and storage medium.

[0006] In a first aspect, the present application provides an elevator control method, which adopts the following technical solution: An elevator control method, comprising: Get the power-off trigger signal of the elevator; According to the power-off trigger signal, the preset brake is controlled to brake the preset car, and the preset backup power supply is started to supply power to the elevator; Get the real-time operating parameters of the elevator; The brake is controlled to release the brake on the car, and the backup power supply is controlled to assist the elevator operation according to the real-time operating parameters.

[0007] By adopting the above technical solution, when the power-off trigger signal of the elevator is detected, the brake is controlled to brake the car, thereby preventing the car from falling freely and causing personal injury, and the backup power supply is controlled to assist the elevator operation according to the real-time operating parameters of the elevator, so that people can reach the required floor as much as possible and leave the car safely, thereby preventing people from feeling anxious in the closed car and further taking dangerous actions, thereby improving the safety of the elevator control system.

[0008] Optionally, the step of controlling the backup power supply to assist the elevator operation according to the real-time operation parameters includes: Analyze real-time operating parameters to determine the elevator's elevator operating status; Determine whether the elevator operation status meets the requirements of the preset parking status; If it meets the requirements, the brake will continue to be controlled to brake the car, and the personnel will be prompted to leave the car according to the preset leaving prompt information; If not, the real-time operating parameters are analyzed to determine the floors to be moved and the power-off floors of the elevator; Analyze the floors that need to be moved and the floors without power supply to determine the floors where the elevator stops; Get the remaining power of the backup power supply; The backup power supply is controlled according to the remaining power of the power supply and the elevator stop floor to assist the elevator operation.

[0009] By adopting the above technical solution, when the elevator operating state meets the parking state requirements, it means that the elevator is just parked at a floor, so the brake is controlled to brake the car and remind people to leave the car as soon as possible; when it does not meet the requirements, it means that the elevator is in operation, so the backup power supply is controlled according to the remaining power of the power supply and the elevator parking floor to assist the elevator operation, thereby improving the safety and convenience of elevator control.

[0010] Optionally, the step of controlling the backup power supply to assist the elevator operation according to the remaining power of the power supply and the elevator stop floor includes: Analyze the remaining power of the power supply to determine the maximum mobile parking floor; Determine whether the elevator stop floor meets the requirements of the maximum moving stop floor; If not, determine whether the maximum mobile stop floor meets the preset minimum mobile stop floor requirements; If the minimum moving stop floor requirement is not met, the brake will continue to be controlled to brake the car; If the minimum moving stop floor requirement is met, the backup power supply is controlled to assist the elevator in running according to the preset nearest stop trigger signal; If it meets the requirements, the backup power supply will be controlled according to the elevator stop floor to assist the elevator operation.

[0011] By adopting the above technical solution, when it is determined that the elevator stop floor does not meet the requirements of the maximum moving stop floor and does not meet the requirements of the minimum moving stop floor, it indicates that the backup power supply has less power, so the brake is controlled to brake the car. When it meets the requirements of the minimum moving stop floor, it indicates that the backup power supply can support the elevator to move to the minimum floor, so that the backup power supply is controlled according to the most recent stop trigger signal to assist the elevator operation, thereby improving the safety of elevator control.

[0012] Optionally, the step of analyzing the remaining power of the power supply to determine the maximum mobile stop floor includes: Analyze real-time operating parameters to determine the real-time movement type and real-time load weight of the elevator; Determining whether the real-time movement type is a preset ascending movement type or a preset descending movement type; If it is an ascending movement type, the maximum moving stop floor is determined based on the real-time load weight, the remaining power of the power supply and the preset power ascending floor relationship; If it is a descending movement type, the maximum moving stop floor is determined based on the real-time load weight, the remaining power of the power supply and the preset power descent floor relationship.

[0013] By adopting the above technical solution, the real-time movement type is analyzed to determine whether the elevator is ascending or descending, and then the maximum moving stop floor is determined according to the relationship between the floors when the power level increases and the floors when the power level decreases, as well as the real-time load-bearing weight of the elevator and the remaining power of the power supply, thereby improving the accuracy of the maximum moving stop floor.

[0014] Optionally, the step of controlling the backup power supply to assist the elevator operation according to the preset nearest stop trigger signal includes: Analyze real-time operating parameters to determine the elevator's power-off height; Analyze the power-off height and the preset elevator parking height to determine the elevator moving distance difference corresponding to the elevator parking height; Sorting and analyzing the elevator moving distance differences to determine the shortest moving distance; Get the actual stop floor corresponding to the shortest moving distance; The backup power supply is controlled according to the actual stop floor to assist the elevator operation.

[0015] By adopting the above technical solution, the power-off height and the elevator stopping height are subtracted to obtain the elevator moving distance difference. After comparing all the elevator moving distance differences, the shortest moving distance is selected, and the actual stopping floor corresponding to the shortest moving distance is called. The backup power supply is controlled according to the actual stopping floor to assist the elevator operation, so that the elevator can transport people to the nearest floor as soon as possible, thereby improving the safety of elevator control.

[0016] Optionally, the steps of controlling the backup power supply to assist the elevator operation include: When the backup power supply assists the elevator in operation, the reconnection trigger signal of the preset main power supply is obtained in real time; Control the standby power supply to shut down according to the reconnection trigger signal, and control the main power supply to supply power to the elevator; Control the main power supply to assist the elevator operation according to the real-time operating parameters.

[0017] By adopting the above technical solution, during the process of the backup power supply assisting the elevator operation, once the reconnection trigger signal of the main power supply is detected, the main power supply and the backup power supply are controlled to switch to power the elevator, and the main power supply continues to be controlled according to the original real-time operating parameters to assist the normal operation of the elevator, thereby improving the convenience of elevator control.

[0018] Optionally, after the backup power supply is controlled to assist the elevator in running according to the real-time operating parameters, a step of leaving the supervision is also included, and the specific steps include: Get the elevator's parking trigger signal; Control the car to open according to the parking trigger signal, and prompt people to leave the car according to the preset departure prompt information; Acquire a car detection image of the car; Perform image recognition analysis on the car detection image to determine whether there are preset human features in the car detection image; If it exists, continue to prompt the person to leave the car according to the leaving prompt information, and continue to obtain the car detection image of the car for cyclic judgment; If it does not exist, the car will be controlled to close and lock.

[0019] By adopting the above technical solution, when the elevator's stop trigger signal is detected, the car is immediately controlled to open, and the personnel are reminded to leave the car as soon as possible. The car detection image is collected and image recognition is performed. When it is determined that there are no human features in the car detection image, the car is closed and locked to prevent people from entering the car again, thereby improving the safety of elevator control.

[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The embodiment of the present application discloses a control method for an elevator power failure emergency stop, specifically disclosing a processing terminal, a backup power supply, a brake and an elevator. The processing terminal is respectively connected to the backup power supply, the brake and the elevator through data wires to realize data interaction and control. When the processing terminal receives a power failure trigger signal of the elevator, the processing terminal controls the brake to brake the elevator car to prevent the car from falling freely, and starts the backup power supply to power the elevator. At this time, the real-time operating parameters of the elevator are called to control the brake to release the brake on the car, and the backup power supply is controlled according to the real-time operating parameters to assist the elevator operation, so as to transport people to the required floors as much as possible without keeping people in a closed car all the time, avoiding anxiety and making dangerous actions, thereby improving the safety of elevator control.

[0036] Reference Figure 1 , the embodiment of the present application discloses an elevator control method, comprising the following steps: Step S100: Obtain the power-off trigger signal of the elevator.

[0037] Among them, the power-off trigger signal refers to a signal indicating that the elevator is powered off. The power monitoring circuit continuously detects the status of the main power supply. Once it is determined that the main power supply is powered off, the power-off trigger signal is immediately sent to the processing terminal.

[0038] Step S101: Control a preset brake to brake a preset car according to a power failure trigger signal, and start a preset backup power supply to power the elevator.

[0039] Among them, when the processing terminal receives a power-off trigger signal, it indicates that the main power supply of the elevator is cut off. Therefore, the processing terminal controls the brake to brake the car to prevent the car from falling freely, and starts the backup power supply to power the elevator, providing basic support for the continued operation of the elevator.

[0040] The brake is a safety device that stops the elevator quickly. Disc brakes can be used. The car is the part of the elevator that moves passengers or goods. The backup power supply is the power supply that powers the elevator when the main power supply of the elevator is cut off. The specific type is determined by the operator according to the actual situation.

[0041] Step S102: Acquire the real-time operating parameters of the elevator.

[0042] Among them, real-time operating parameters refer to the specific parameters of the elevator during operation, including the operating status of the elevator, such as parking, rising and falling, including the floor to which people need to move, the floor when the power is off, the height when the power is off, and the weight carried. They are detected by various sensors installed on the elevator and sent to the processing terminal.

[0043] Step S103: Control the brake to release the brake on the car, and control the backup power supply to assist the elevator operation according to the real-time operation parameters.

[0044] After the processing terminal receives the real-time operation parameters, the processing terminal controls the brake to release the brake on the car, so that the car is in a movable state, and controls the backup power supply to assist the elevator operation according to the real-time operation parameters. The specific method is referred to Figure 2 Steps are taken to enable the elevator to transport people to the required floors as much as possible, preventing people from feeling anxious in the closed cabin and making further dangerous actions, thereby improving the safety of elevator control.

[0045] Reference Figure 2 The steps of controlling the operation of the backup power supply to assist the elevator according to the real-time operation parameters include: Step S200: Analyze the real-time operating parameters to determine the elevator operating status of the elevator.

[0046] The elevator operation status refers to the state of the elevator before power failure, including two states: parking and moving. The processing terminal identifies and calls the elevator state in the real-time operation parameters.

[0047] Step S201: Determine whether the elevator running state meets the preset parking state requirements.

[0048] The parking state refers to the state in which the elevator is in a parking state, and the parking state requirement refers to being consistent with the parking state, which are all stored in the processing terminal by the operator. The processing terminal determines whether the elevator operation state is consistent with the parking state, thereby determining whether the car is parked at a floor.

[0049] Step S2011: If it meets the requirements, continue to control the brake to brake the car, and prompt the person to leave the car according to the preset departure prompt information.

[0050] Among them, if the processing terminal determines that the elevator operating status is consistent with the parking status, it means that the car is parked at a floor. At this time, for the safety of the personnel, the brake continues to be controlled to brake the car, and the car is no longer controlled to continue moving. The personnel are prompted to leave the car according to the departure prompt information, thereby ensuring the safety of the personnel to the greatest extent.

[0051] The departure prompt information refers to the information that prompts people to leave the car. Voice and lighting effects can be used to prompt people.

[0052] Step S2012: If not, the real-time operating parameters are analyzed to determine the floors to be moved and the power-off floors of the elevator.

[0053] Among them, if the processing terminal determines that the elevator operating status is inconsistent with the parking status, it means that the car is in a moving state when the power is turned off. At this time, the car needs to be moved to a floor to allow people to leave the car safely. Therefore, after analyzing the real-time operating parameters, the floors that need to be moved and the power-off floors are determined to provide data support for the subsequent control of the elevator to continue operating.

[0054] The floor to be moved refers to the floor to which the people in the elevator need to move, and the power-off floor refers to the floor of the car when the elevator loses power. The processing terminal identifies and calls the floor to be moved and the power-off floor in the real-time operating parameters.

[0055] Step S202: Analyze the floors to be moved and the power-off floors to determine the elevator stop floors.

[0056] Among them, the elevator stop floor refers to the number of floors the elevator can move to and the specific floor it stops at after moving. The processing terminal identifies the floor closest to the power-off floor among the floors to be moved, and defines this floor as the stop floor. The difference between the two floors is then calculated to get the number of floors, thereby ensuring that some people can reach the floors they need to reach and that all people can leave the car as soon as possible.

[0057] Step S203: Obtain the remaining power of the backup power supply.

[0058] The remaining power of the power supply refers to the remaining power of the backup power supply, which is obtained by the battery management system detecting the power of the backup power supply and sending it to the processing terminal.

[0059] Step S204: Control the backup power supply to assist the elevator operation according to the remaining power of the power supply and the elevator stop floor.

[0060] Among them, after the processing terminal determines the remaining power of the power supply, the backup power supply is controlled to assist the elevator operation according to the remaining power of the power supply and the elevator stop floor. The specific method is referred to Figure 3 steps, thereby ensuring the operation of the elevator according to the actual situation of the backup power supply, thereby improving the safety of elevator control.

[0061] Reference Figure 3 The steps of controlling the backup power supply to assist the elevator operation according to the remaining power of the power supply and the elevator stop floor include: Step S300: Analyze the remaining power of the power supply to determine the maximum mobile stop floor.

[0062] The maximum mobile stop floor refers to the maximum number of floors that the backup power supply can support the car to move in the current state. It is determined by the processing terminal after analyzing the remaining power of the power supply. The specific method is referred to Figure 4 steps.

[0063] Step S301: Determine whether the elevator stop floor meets the requirement of the maximum moving stop floor.

[0064] The requirement of the maximum movable stop floor refers to not exceeding the number of floors corresponding to the maximum movable stop floor. The processing terminal determines whether the number of movable floors corresponding to the elevator stop floor does not exceed the number of floors corresponding to the maximum movable stop floor, thereby determining whether the backup power supply can support the car to move to the stop floor corresponding to the elevator stop floor.

[0065] Step S3011: If not, determine whether the maximum moving stop floor meets the preset minimum moving stop floor requirement.

[0066] Among them, the minimum mobile stop floor refers to the moving floor is 1, the minimum mobile stop floor requirement refers to the number of floors not less than the minimum mobile stop floor, which are stored in the processing terminal by the operator. If the processing terminal determines that the number of movable floors corresponding to the elevator stop floor exceeds the number of floors corresponding to the maximum movable stop floor, it means that the backup power supply cannot support the car to move to the stop floor corresponding to the elevator stop floor. Therefore, it is judged whether the number of floors corresponding to the maximum movable stop floor is not less than the number of floors corresponding to the minimum movable stop floor, so as to determine whether the backup power supply can support the movement of the car.

[0067] Step S30111: If the requirement of the minimum moving stop floor is not met, continue to control the brake to brake the car.

[0068] Among them, if the processing terminal determines that the floor number corresponding to the maximum moving stop floor is less than the floor number corresponding to the minimum moving stop floor, it means that the backup power supply cannot support the movement of the car, so the brake continues to be controlled to brake the car to prevent the car from falling freely.

[0069] Step S30112: If the minimum moving stop floor requirement is met, the backup power supply is controlled to assist the elevator in running according to the preset nearest stop trigger signal.

[0070] If the processing terminal determines that the number of floors corresponding to the maximum mobile stop floor is not less than the number of floors corresponding to the minimum mobile stop floor, it means that the backup power supply can support the car to move to the nearest floor. Therefore, the backup power supply is controlled according to the nearest stop trigger signal to assist the elevator to run. For specific methods, refer to Figure 5 steps to ensure personnel safety within the capabilities of the backup power supply.

[0071] The nearest stop trigger signal is a signal that controls the backup power supply to assist the elevator operation and moves the elevator car to the nearest floor, and is stored in the processing terminal by the operator.

[0072] Step S3012: If it meets the requirements, the backup power supply is controlled to assist the elevator operation according to the elevator stop floor.

[0073] Among them, if the processing terminal determines that the number of movable floors corresponding to the elevator stop floor does not exceed the number of floors corresponding to the maximum movable stop floor, it means that the backup power supply can support the car to move to the stop floor corresponding to the elevator stop floor. Therefore, the backup power supply is controlled to assist the elevator operation and move the car to the stop floor corresponding to the elevator stop floor, so that some people can reach the floor they need to reach and all personnel can leave the car.

[0074] Reference Figure 4 , the steps of analyzing the remaining power of the power supply to determine the maximum mobile stop floor include: Step S400: Analyze the real-time operation parameters to determine the real-time movement type and real-time load-bearing weight of the elevator.

[0075] Among them, the real-time movement type refers to the movement state of the elevator car, including rising and falling, and the real-time load-bearing weight refers to the weight carried by the elevator car, which is obtained by the processing terminal identifying and calling the real-time movement type and real-time load-bearing weight in the real-time operation parameters.

[0076] Step S401: determining whether the real-time movement type is a preset ascending movement type or a preset descending movement type.

[0077] The ascending movement type refers to the movement type of the car being ascending, and the descending movement type refers to the movement type of the car being descending, both of which are stored in the processing terminal by the operator.

[0078] The processing terminal determines whether the real-time movement type is an ascending movement type or a descending movement type, thereby determining whether the car is ascending or descending, providing data support for the subsequent determination of the maximum moving stop floor of the elevator.

[0079] Step S4011: If it is an ascending movement type, the maximum moving stop floor is determined based on the real-time load weight, the remaining power of the power supply and the preset power ascending floor relationship.

[0080] Among them, if the processing terminal determines that the real-time movement type is an ascending movement type, it means that the car was in an ascending state before the power was cut off. Therefore, the power ascending floor relationship is called to determine the maximum moving stop floor based on the real-time load weight, remaining power of the power supply and the power ascending floor relationship.

[0081] The relationship between power level and rising floors refers to the correspondence between power level, load-bearing weight and rising floors. When the power level is determined, the greater the load-bearing weight, the smaller the rising floors. The operator actually changes the power level, and conducts experiments with different load-bearing weights under different power states, and records the rising floors under this state. Finally, the three are matched one by one to form a mapping table.

[0082] The maximum mobile stop floor in this step is consistent with the maximum mobile stop floor in step S300, and is obtained by searching the mapping table corresponding to the power increase floor relationship by the processing terminal according to the real-time load weight and the remaining power of the power supply.

[0083] Step S4012: If it is a descending movement type, the maximum moving stop floor is determined based on the real-time load weight, the remaining power of the power supply and the preset power descending floor relationship.

[0084] Among them, if the processing terminal determines that the real-time movement type is a descending movement type, it means that the car was in a descending state before the power was cut off. Therefore, the power reduction floor relationship is called to determine the maximum moving stop floor based on the real-time load weight, remaining power of the power supply and the power reduction floor relationship.

[0085] The relationship between power level and floors descended refers to the correspondence between power level, load-bearing weight and floors descended. When the power level is determined, the greater the load-bearing weight, the smaller the floors descended. The operator changes the power level in practice, and conducts experiments with different load-bearing weights under different power levels, and records the floors descended under this state. Finally, the three are matched one by one to form a mapping table.

[0086] The maximum mobile stop floor in this step is consistent with the maximum mobile stop floor in step S300, and is obtained by searching the mapping table corresponding to the power reduction floor relationship by the processing terminal according to the real-time load weight and the remaining power of the power supply.

[0087] Reference Figure 5 The steps of controlling the operation of the elevator with a backup power supply according to the preset nearest stop trigger signal include: Step S500: Analyze the real-time operating parameters to determine the power-off height of the elevator.

[0088] The power-off height refers to the height of the elevator car when the elevator is powered off, and is obtained by the processing terminal identifying and calling the power-off height in the real-time operating parameters.

[0089] Step S501: Analyze the power-off height and the preset elevator parking height to determine the elevator moving distance difference corresponding to the elevator parking height.

[0090] The elevator stop height refers to the height of the car when it stops at each floor. The operator inputs the elevator stop height according to the actual situation and stores it in the processing terminal. The elevator moving distance difference refers to the distance when the car moves from the current height to the remaining floors. The processing terminal calculates the absolute value of the difference between the power-off height and the elevator stop height.

[0091] Step S502: sort and analyze the elevator moving distance differences to determine the shortest moving distance.

[0092] The shortest moving distance refers to the shortest distance that the elevator moves from the current height to the remaining floors. The processing terminal sorts the elevator moving distance differences, and selects the smallest elevator moving distance difference to obtain the shortest moving distance.

[0093] Step S503: Obtain the actual stop floor corresponding to the shortest moving distance.

[0094] Among them, the actual stopping floor refers to the floor where the car can actually stop. The processing terminal determines the corresponding elevator stopping height according to the shortest moving distance, and then determines the floor according to the elevator stopping height and the corresponding relationship between the height and the floor.

[0095] Step S504: Control the backup power supply to assist the elevator in running according to the actual stop floor.

[0096] Among them, after the processing terminal determines the actual stopping floor, the processing terminal controls the backup power supply to assist the elevator operation, thereby controlling the movement of the car and stopping at the actual stopping floor, so that people can leave the car as soon as possible.

[0097] Reference Figure 6 , the steps of controlling the backup power supply to assist the elevator operation include: Step S600: When the backup power supply assists the elevator in running, a reconnection trigger signal of the preset main power supply is obtained in real time.

[0098] Among them, when the backup power supply assists the elevator operation, the re-trigger signal of the main power supply is detected in real time to provide data support for the subsequent control of the elevator operation.

[0099] The main power supply refers to the main power supply for the operation of the elevator. The reconnection trigger signal refers to the trigger signal for the reconnection of the main power supply. The power monitoring circuit continuously detects the status of the main power supply. Once the main power supply is reconnected, the re-trigger signal is sent to the processing terminal.

[0100] Step S601: Control the backup power supply to shut down according to the reconnection trigger signal, and control the main power supply to supply power to the elevator.

[0101] Among them, when the processing terminal receives the re-trigger signal, it indicates that the main power supply can supply power to the elevator. Therefore, the processing terminal controls the backup power supply to shut down and controls the main power supply to supply power to the elevator, thereby meeting the normal use of the elevator.

[0102] Step S602: Control the main power supply to assist the elevator operation according to the real-time operation parameters.

[0103] Among them, after the processing terminal controls the main power supply to supply power to the elevator, the processing terminal controls the main power supply to assist the elevator operation according to the real-time operating parameters, so that the elevator can transport personnel to the corresponding floors according to normal personnel needs, ensuring the normal use of the elevator.

[0104] Reference Figure 7 After the standby power supply is controlled to assist the elevator in running according to the real-time operating parameters, it also includes the step of leaving the supervision. The specific steps include: Step S700: Obtain the elevator's parking trigger signal.

[0105] Among them, the stop trigger signal refers to the trigger signal for the car to stop at a certain floor. The photoelectric sensing device installed on each floor senses the movement of the car, and when it determines that the floor is the floor that needs to stop, it controls the car to stop moving and sends the stop trigger signal to the processing terminal.

[0106] Step S701: Control the car to open according to the parking trigger signal, and prompt the person to leave the car according to the preset departure prompt information.

[0107] Among them, after the processing terminal receives the stop trigger signal, it indicates that the car is stopped at a floor, so the processing terminal controls the car to open, and prompts the personnel to leave the car according to the departure prompt information, thereby ensuring the safety of the personnel.

[0108] The leaving prompt information in this step is consistent with the leaving prompt information in step S2011, and will not be repeated here.

[0109] Step S702: Acquire a car detection image of the car.

[0110] Among them, the car detection image refers to the image inside the car, which is photographed by a camera installed in the car and sent to the processing terminal.

[0111] Step S703: performing image recognition analysis on the car detection image to determine whether there are preset human features in the car detection image.

[0112] After receiving the car detection image, the processing terminal controls the trained personnel recognition model to perform image recognition analysis on the car detection image, thereby determining whether there are personnel features in the car detection image, thereby determining whether there are personnel staying in the car. Personnel features refer to features representing personnel in the image.

[0113] Step S7031: If it exists, continue to prompt the person to leave the car according to the leaving prompt information, and continue to obtain the car detection image of the car for cyclic judgment.

[0114] Among them, if the processing terminal determines that there are still human features in the car detection image, it means that there are still people staying in the car. Therefore, the people are prompted to leave the car according to the departure prompt information, and the car detection image continues to be collected, so as to continue to pay attention to the situation in the car.

[0115] Step S7032: If it does not exist, control the car to close and lock.

[0116] Among them, if the processing terminal determines that there are no human features in the car detection image, it means that there is no person staying in the car, so the car is closed and locked to prevent people from entering the car again, thereby ensuring the safety of the people.
