Description

Technical Field

[0001] The present invention relates to the technical field of parking management, and particularly relates to a vehicle following prevention device and a control method for a parking lot. Background Art

[0002] In the related art, during the process of detecting vehicles at the entrance and exit of a parking lot, the induction information of an induction coil is directly obtained to determine whether a vehicle has passed. After the induction information of the induction coil is converted from triggered to untriggered, the barrier gate is controlled to close to manage the vehicles entering and leaving the parking lot.

[0003] However, this method often encounters the situation of vehicle following. That is, when the previous vehicle exits the parking lot, the subsequent vehicle closely follows it. Because the distance between the two vehicles is relatively close, the induction information of the induction coil remains in the triggered state all the time, and the barrier gate will not close. As a result, the subsequent vehicle can directly drive out of the parking lot, which leads to loopholes in the vehicle management of the parking lot and causes property losses to the operator. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems in the above technologies to some extent. For this reason, one object of the present invention is to provide a vehicle following prevention device for a parking lot, which can effectively avoid the occurrence of vehicle following, improve the vehicle management ability of the parking lot, and ensure the property safety of the operator.

[0005] The second object of the present invention is to provide a control method for the vehicle following prevention device for a parking lot.

[0006] To achieve the above object, an embodiment of the first aspect of the present invention provides a following vehicle prevention device for a parking lot, which includes a barrier gate disposed at the entrance and exit of the parking lot for releasing or intercepting vehicles entering and leaving the parking lot when opening and closing; a first sensor disposed on one side of the vehicle driving direction relative to the barrier gate for sensing the vehicle on one side of the vehicle driving direction relative to the barrier gate to obtain first sensing information of the vehicle at this position; a second sensor disposed opposite to the barrier gate for sensing the vehicle at the relative position of the barrier gate to obtain second sensing information of the vehicle at this position; an infrared sensor disposed opposite to the barrier gate for sensing an object at the relative position of the barrier gate to obtain infrared sensing information at this position; a charging unit disposed at the entrance and exit of the parking lot for collecting the parking fees of the vehicle; and a controller respectively connected to the barrier gate, the first sensor, the second sensor, the infrared sensor and the charging unit. The controller controls the charging unit to collect the parking fees of the vehicle according to the first sensing information, controls the barrier gate to open according to the charging result of the charging unit, and controls the opening and closing of the barrier gate according to the second sensing information and the infrared sensing information.

[0007] According to the parking lot anti-following device of the embodiment of the present invention, a barrier gate is set at the entrance and exit of the parking lot. The barrier gate is used to release vehicles when it is opened and intercept vehicles when it is closed, so as to control the vehicles entering and leaving the parking lot. A first sensor is set on one side of the vehicle driving direction opposite to the barrier gate to sense the vehicle at this position through the first sensor. Thus, it can be judged whether there is a vehicle at this position according to the first sensing information obtained by sensing. A second sensor is set at the corresponding position of the barrier gate, so that the vehicle at this position can be sensed through the second sensor, and it can be judged whether there is a vehicle at this position according to the second sensing information obtained by sensing. At the same time, an infrared sensor is set at the corresponding position of the barrier gate to sense the object at this position through the infrared sensor, so that it can be judged whether there is an object at this position according to the infrared sensing information obtained by sensing. A charging unit is set at the entrance and exit of the parking lot to collect the parking fees of the vehicles entering and leaving through the charging unit. A controller is set to be connected to the barrier gate, the first sensor, the second sensor, the infrared sensor and the charging unit respectively. The controller controls the charging unit to collect the parking fees of the vehicle according to the first sensing information sensed by the first sensor, and controls the barrier gate according to the charging result fed back by the charging unit, so that the vehicle can drive out of the parking lot after the barrier gate is opened, and controls the barrier gate to close according to the second sensing information sensed by the second sensor and the infrared sensing information sensed by the infrared sensor, so as to prevent the vehicle behind from following and driving out of the parking lot, thus effectively avoiding the occurrence of following situations, improving the control ability of the parking lot for vehicles, and ensuring the property safety of the operator.

[0008] In addition, the parking lot anti-following device proposed according to the above embodiment of the present invention may also have the following additional technical features:

[0009] Optionally, the first sensor and the second sensor are induction coils.

[0010] Optionally, the charging unit includes a camera. The camera is connected to the controller. The controller controls the camera to take pictures of the side of the vehicle driving direction opposite to the barrier gate according to the first sensing information to obtain the license plate image of the vehicle at this position.

[0011] Optionally, it further includes a server and a communication unit. The communication unit is respectively connected to the controller and the server. The controller sends the license plate image to the server through the connection with the server, so that the server can collect the parking fees of the vehicle according to the license plate image and send the charging result to the controller.

[0012] Optionally, the toll collection unit includes a card dispenser and a card reader. The card dispenser is arranged corresponding to the entrance of the parking lot and is connected to the controller. The controller controls the card dispenser to write time information into the card according to the user's card-taking instruction, and controls the card dispenser to push the card to the user. The card reader is arranged corresponding to the exit of the parking lot and is connected to the controller. The controller reads the time information in the card presented by the user through the card reader, and calculates the parking fee corresponding to the vehicle according to the time information and the current time.

[0013] Optionally, the toll collection unit further includes a cash register, which is connected to the controller. The cash register is used to collect the parking fee according to the parking fee sent by the controller and send the charging result to the controller.

[0014] To achieve the above object, an embodiment of the second aspect of the present invention provides a control method for a following vehicle prevention device in a parking lot, including the following steps: obtaining first induction information and the state information of the gate, and judging whether the first sensor is triggered and whether the gate is in an open state according to the first induction information and the state information; if the first sensor is triggered and the gate is in an open state, obtaining infrared sensing information; judging whether the infrared sensor is triggered according to the infrared sensing information; if the infrared sensor is triggered, obtaining second induction information, and judging whether the second sensor is triggered according to the second induction information; if the second sensor is triggered, judging whether the infrared sensor changes from a triggered state to an untriggered state according to the infrared sensing information; if the infrared sensor changes from a triggered state to an untriggered state, controlling the gate to close.

[0015] According to the control method of the following vehicle prevention device in the parking lot of the embodiment of the present invention, first, obtain the first induction information and the state information of the gate, and judge whether the first sensor is triggered and whether the gate is in an open state according to the first induction information and the state information, that is, judge whether there is a vehicle at the station corresponding to the first sensor and whether the vehicle has met the exit conditions and the gate is open; if so, obtain the infrared sensing information, and judge whether the infrared sensor is triggered according to the infrared sensing information. If the infrared sensor is triggered, it means that there is an object at the station corresponding to the infrared sensor. At this time, obtain the second induction information, and judge whether the second sensor is triggered according to the second induction information. If the second sensor is triggered, it is considered that the object triggering the infrared sensor currently is a vehicle; thus, when the second sensor is triggered, judge whether the infrared sensor changes from a triggered state to an untriggered state according to the infrared sensor information. If so, control the gate to close to prevent subsequent vehicles from following and driving out of the parking lot, so as to effectively avoid the occurrence of following situations, improve the management and control ability of the parking lot for vehicles, and ensure the property safety of the operator.

[0016] In addition, the control method of the anti-tailgating device for a parking lot according to the above embodiments of the present invention may further have the following additional technical features:

[0017] Optionally, after determining that the infrared sensor has switched from a triggered state to an untriggered state based on the infrared sensing information, it further includes: determining whether the first sensor is triggered according to the first sensing information; if so, obtaining the vehicle information of the current vehicle at the position corresponding to the first sensor, and determining whether the current vehicle has paid the fee according to the vehicle information; if so, controlling the barrier gate to remain open; if not, controlling the barrier gate to close.

[0018] Optionally, if it is determined that the current vehicle has paid the fee according to the vehicle information, it is determined whether the vehicle information of the current vehicle is the same as the vehicle information of the previous vehicle leaving the lot; if the same, controlling the barrier gate to close.

[0019] Optionally, after determining that the infrared sensor has switched from a triggered state to an untriggered state based on the infrared sensing information, it further includes: calculating the difference between the current time and the time of the last state change of the infrared sensor; determining whether the difference is less than a preset time threshold; if so, confirming that the current infrared sensing information is fault information and ignoring the current infrared sensing information.

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In the related art, parking lots have poor control over vehicles, and following vehicles often occur, resulting in property losses for operators. According to the parking lot anti-following device of an embodiment of the present invention, the first sensor senses the vehicle on the side of the barrier that is away from the departure direction, the second sensor senses the vehicle at the corresponding position of the barrier, and the infrared sensor senses the object at the shadow position of the barrier; the charging unit collects the parking fee from the vehicle, and the controller is respectively connected to the barrier, the first sensor, the second sensor, the infrared sensor and the charging unit. The controller controls the charging unit to collect the parking fee from the vehicle according to the first sensing information, controls the opening of the barrier according to the charging result of the charging unit, and controls the opening and closing of the barrier according to the second sensing information and the infrared sensing information, thereby effectively avoiding the occurrence of following vehicles, improving the parking lot's control over vehicles, and ensuring the property safety of operators.

[0029] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See also Figure 1 , Figure 1 FIG. 2 is a block diagram of a parking lot following device according to an embodiment of the present invention. Figure 1 As shown, the parking lot anti-following vehicle device includes: a barrier 10, a first sensor 20, a second sensor 30, an infrared sensor 40, a charging unit 50 and a controller 60.

[0032] Among them, the barrier gate 10 is set at the entrance and exit of the parking lot, and the barrier gate 10 is used to release or intercept vehicles entering and leaving the parking lot when opening and closing; that is, when the barrier gate 10 is opened, vehicles are allowed to leave the parking lot through the barrier gate 10, and when the barrier gate 10 is closed, vehicles are intercepted and prohibited from passing.

[0033] The first sensor 20 is arranged on the side of the vehicle driving-in direction relative to the gate 10. It can be understood that after the parking lot is set up, there is a driving route. At the entrance of the parking lot, when the vehicle enters the parking lot from the outside, taking the gate 10 as the dividing line, the outside side is the vehicle driving-in direction, and the inside side of the parking lot is the vehicle driving-out direction; at the exit of the parking lot, when the vehicle drives out of the parking lot, taking the gate 10 as the dividing line, the outside side is the vehicle driving-out direction, and the inside side of the parking lot is the vehicle driving-in direction; the first sensor 20 is used to sense the vehicle on the side of the vehicle driving-in direction relative to the gate 10 to obtain the first sensing information of the vehicle at this position.

[0034] As an example, an induction coil is arranged on the side of the vehicle driving-in direction relative to the gate 10 to sense the vehicle at this position. Thus, when the induction coil is triggered, it can be considered that there is a vehicle driving in at the current position.

[0035] The second sensor 30 is arranged relative to the gate 10, that is to say, the second sensor 30 is arranged at a position opposite to the gate 10 to sense the vehicle at the position where the gate 10 is located, so as to obtain the second sensing information at this position.

[0036] As an example, an induction coil is arranged at a position relative to the gate 10 to sense the vehicle at this position. Thus, when the induction coil is triggered, it can be considered that there is a vehicle driving in at the current position, and when the induction coil changes from the triggered state to the untriggered state, it can be considered that a vehicle has driven out of the parking lot, or the vehicle has reversed.

[0037] The infrared sensor 40 is arranged relative to the gate 10. The infrared sensor 40 is used to sense the object at the position relative to the gate 10 to obtain the infrared sensing information at this position.

[0038] As an example, as Figure 2 shown, the infrared sensor 40 is arranged in parallel with the gate 10 and is arranged on the side of the vehicle driving-out direction with the gate 10 as the dividing line, or it can be arranged directly below the gate 10. Thus, when the infrared sensor 40 is directly below the gate 10 or is extremely close to the gate 10 in the driving-out direction, when the state of the infrared sensor 40 changes from triggered to untriggered, it is considered that the current vehicle has driven out of the parking lot. At this time, controlling the gate 10 to close can effectively prevent the following vehicle from following and driving out of the parking lot.

[0039] The charging unit 50 is arranged at the entrance and exit of the parking lot. The charging unit 50 is used to collect the parking fees of the vehicle.

[0040] The controller 60 is respectively connected to the gate 10, the first sensor 20, the second sensor 30, the infrared sensor 40 and the charging unit 50. The controller 60 controls the charging unit 50 to collect the parking fee of the vehicle according to the first sensing information sensed by the first sensor 20. That is to say, when a vehicle enters on the side of the vehicle driving direction relative to the gate, the charging unit 50 is controlled to collect the parking fee of the currently entering vehicle. After the charging unit 50 collects the parking fee, the controller 60 controls the gate 10 according to the charging result. It can be understood that after the current vehicle completes the payment of the parking fee, the charging unit 50 sends a payment completion message to the controller 60 so that the controller 60 can open the gate 10 to release the current vehicle. The controller 60 controls the opening and closing of the gate 10 according to the second sensing information sensed by the second sensor 30 and the infrared sensing information sensed by the infrared sensor 40.

[0041] It should be noted that when the second sensor 30 and the infrared sensor 40 are triggered simultaneously, it can be considered that the object triggering the infrared sensor 40 at the relative position of the gate 10 is a vehicle, and other objects (such as pedestrians, bicycles, etc.). Thus, when the state of the second sensor 30 changes from triggered to untriggered, the gate 10 can be controlled to close, thereby effectively preventing the following vehicle from leaving the parking lot.

[0042] Among them, there are various ways to set the charging unit 50.

[0043] As an example, as Figure 3 shown, the charging unit 50 includes a camera 51. The camera 51 is connected to the controller 60. The controller 60 controls the camera 51 to take a picture of the side of the vehicle driving direction relative to the gate 10 according to the first sensing information to obtain the license plate image of the vehicle at this position.

[0044] That is to say, when the first sensor 20 senses the first sensing information, it is considered that there is currently a vehicle at this position. Thus, the controller 60 controls the camera 51 according to the first sensing information to obtain the license plate image of the current vehicle, and then the license plate image can be recognized subsequently to obtain the license plate information of the vehicle, so as to calculate the parking fee of the vehicle according to the license plate information.

[0045] As another example, the anti-tailgating device for the parking lot further includes a server 70 and a communication unit 80. The communication unit 80 is respectively connected to the controller 60 and the server 70. The controller 60 sends the license plate image to the server 70 through the connection with the server 70, so that the server 70 charges the parking fee of the vehicle according to the license plate image and sends the charging result to the controller 60. It can be understood that after receiving the license plate image, the server 70 can identify the license plate image according to the image recognition algorithm to obtain the license plate information corresponding to the current vehicle, and then calculate the parking fee of the current vehicle according to the license plate information and charge the parking fee according to the calculation result. Specifically, a charging QR code can be set at the exit of the parking lot. After the user scans the charging QR code with their mobile terminal, enters the license plate information of the current vehicle, and sends the license plate information to the server 70 through the mobile terminal, the server 70 sends the payment order generated according to the parking fee calculation result to the user's mobile terminal according to the received license plate information. Then, after receiving the payment order, the user pays the parking fee according to the payment order to complete the collection of the parking fee. Then, the server 70 sends the charging result to the controller 60 so that the controller 60 controls the barrier gate according to the charging result.

[0046] As yet another example, as Figure 4 shown, the charging unit 50 includes a card dispenser 52 and a card reader 53. Among them, the card dispenser 52 is set at the entrance of the parking lot so that the vehicle can get a card through the card dispenser 52 when entering the parking lot. The card dispenser 52 is connected to the controller 60. The controller 60 controls the card dispenser to write the time information into the card according to the user's card-taking instruction and controls the card dispenser 52 to push the card to the user. The card reader 53 is set at the exit of the parking lot. The card reader 53 is connected to the controller 60. The controller 60 reads the card shown by the user through the card reader 53 to obtain the time information therein, calculates the parking duration of the vehicle according to the time information and the current time of the system, and calculates the parking fee according to the parking duration and the charging rules of the parking lot.

[0047] In some embodiments, the charging unit 50 further includes a cash register 54. The cash register 54 is connected to the controller 60. The cash register 54 is used to collect the parking fee of the vehicle according to the parking fee sent by the controller 60 and send the charging result to the controller 60 so that the controller 60 controls the opening and closing of the barrier gate according to the charging result.

[0048] In summary, for the anti-tailgating device of a parking lot according to an embodiment of the present invention, a barrier gate is provided at the entrance and exit of the parking lot. The barrier gate is used to release vehicles when it is opened and intercept vehicles when it is closed, so as to control the vehicles entering and leaving the parking lot. A first sensor is provided on one side of the vehicle driving direction opposite to the barrier gate to sense the vehicle at this position through the first sensor. Thus, it can be determined whether there is a vehicle at this position according to the first sensing information obtained by sensing. A second sensor is provided at the corresponding position of the barrier gate, so that the vehicle at this position can be sensed through the second sensor, and it can be determined whether there is a vehicle at this position according to the second sensing information obtained by sensing. At the same time, an infrared sensor is provided at the corresponding position of the barrier gate to sense the object at this position through the infrared sensor, so that it can be determined whether there is an object at this position according to the infrared sensing information obtained by sensing. A charging unit is provided at the entrance and exit of the parking lot to collect the parking fees of the vehicles entering and leaving through the charging unit. A controller is connected to the barrier gate, the first sensor, the second sensor, the infrared sensor and the charging unit respectively, and controls the charging unit to collect the parking fees of the vehicle according to the first sensing information sensed by the first sensor, and controls the barrier gate according to the charging result feedback by the charging unit, so that the vehicle can drive out of the parking lot after the barrier gate is opened, and controls the barrier gate to close according to the second sensing information sensed by the second sensor and the infrared sensing information sensed by the infrared sensor, so as to prevent the vehicle behind from tailgating and driving out of the parking lot, thus effectively avoiding the occurrence of tailgating, improving the control ability of the parking lot for vehicles, and ensuring the property safety of the operator.

[0049] To implement the above embodiment, an embodiment of the present invention also proposes a control method for an anti-tailgating device of a parking lot, as Figure 5 shown. The control method of the anti-tailgating device of the parking lot includes the following steps:

[0050] S101, obtain the first sensing information and the state information of the barrier gate, and determine whether the first sensor is triggered and whether the barrier gate is in the open state according to the first sensing information and the state information.

[0051] It can be understood that when the first sensor is triggered and the barrier gate is in the open state, it can be considered that the vehicle currently at the corresponding position of the first sensor has met the exit conditions (for example, there is no parking fee to be paid, monthly rental vehicle, designated released vehicle, etc.). Therefore, the controller controls the barrier gate to open to release the current vehicle.

[0052] As an example, the first sensing information includes 0 and 1. When the first sensing information is 0, it indicates that the first sensor is in an untriggered state. When the first sensing information is 1, it indicates that the first sensor is in a triggered state. The status information of the barrier gate also includes open and closed. Thus, the controller can obtain the triggered state of the first sensor and the open / closed state of the barrier gate based on the first sensing information and the status information.

[0053] S102, if the first sensor is triggered and the barrier gate is in an open state, then obtain the infrared sensing information.

[0054] S103, determine whether the infrared sensor is triggered according to the infrared sensing information.

[0055] S104, if the infrared sensor is triggered, then obtain the second sensing information and determine whether the second sensor is triggered according to the second sensing information.

[0056] S105, if the second sensor is triggered, then determine whether the infrared sensor changes from a triggered state to an untriggered state according to the infrared sensing information.

[0057] S106, if the infrared sensor changes from a triggered state to an untriggered state, then control the barrier gate to close.

[0058] That is to say, if the first sensor is triggered and the barrier gate is in an open state, the vehicle can drive out of the parking lot through the open barrier gate. If the vehicle continues to drive out, it will surely trigger the infrared sensor. Therefore, when the infrared sensor is triggered, further obtain the second sensing information. If the second sensing information is also triggered, it means that the object triggering the infrared sensor currently is a vehicle, rather than other objects. Furthermore, on the premise that the object triggering the infrared sensor currently is a vehicle, determine whether the state of the infrared sensor changes from a triggered state to an untriggered state. If so, control the barrier gate to close, so as to effectively prevent the following vehicle from following and driving out of the parking lot.

[0059] In some embodiments, in order to reduce the opening and closing frequency of the barrier gate and improve the service life of the barrier gate, as Figure 6 shown, after determining that the infrared sensor changes from a triggered state to an untriggered state according to the infrared sensing information, it further includes:

[0060] S201, determine whether the first sensor is triggered according to the first sensing information; if so, execute step S203, if not, execute step S202.

[0061] S202, control the barrier gate to close.

[0062] S203, obtain the vehicle information of the current vehicle at the position corresponding to the first sensor.

[0063] S204. Determine whether the current vehicle has paid the fee according to the vehicle information. If so, execute step S205; if not, execute step S202.

[0064] S205. Control the barrier gate to maintain the open state.

[0065] That is to say, after determining that the infrared sensor has changed from the triggered state to the untriggered state according to the infrared sensing information, further determine whether there is a vehicle at the relative position of the first sensor. If there is a vehicle at the relative position of the first sensor at this time, obtain the vehicle information of the vehicle, and determine whether the vehicle at the relative position of the first sensor has paid the fee according to the vehicle information. If so, control the barrier gate to maintain the open state; if not, directly control the barrier gate to close, thereby effectively reducing the usage frequency of the barrier gate and improving the service life of the barrier gate.

[0066] In some embodiments, in order to further prevent vehicles from following each other out of the parking lot, after determining that the current vehicle has paid the fee according to the vehicle information, it is also necessary to determine whether the vehicle information of the current vehicle is the same as the vehicle information of the previous vehicle leaving the lot. If they are the same, it is considered that the current vehicle is a following vehicle, and the barrier gate is directly controlled to close.

[0067] In some embodiments, in order to exclude misjudgments caused by abnormal device information such as infrared jumps, after determining that the infrared sensor has changed from the triggered state to the untriggered state according to the infrared sensing information, it also includes calculating the difference between the current time and the time of the last state change of the infrared sensor, and determining whether the difference is less than a preset time threshold. If so, confirm that the current infrared sensing information is fault information and ignore the current infrared sensing information to prevent incorrect operations caused by fault information.

[0068] In a specific embodiment of the present invention, as Figure 7 shown, the control method of the anti-following vehicle device in the parking lot includes the following steps:

[0069] S301. Determine whether the first sensing information is 1 and whether the state of the barrier gate is open; if so, execute step S302.

[0070] Among them, when the first sensing information is 1, it means that the first sensor is triggered; when the first sensing information is 0, it means that the first sensor is not triggered.

[0071] S302. Determine whether the infrared sensing information has changed from 0 to 1; if so, execute step S303.

[0072] Among them, when the infrared sensing information is 0, it means that the infrared sensor is not triggered; if the infrared sensing information is 1, it means that the infrared sensor is triggered.

[0073] S303. Determine whether the second sensing information is 1. If it is, execute step S304.

[0074] S304. Determine whether the infrared sensing information changes from 1 to 0. If it is, execute step S305.

[0075] S305. Calculate the difference between the current time and the time when the infrared sensor last changed its state.

[0076] S306. Determine whether this difference is less than a preset time threshold. If it is, return to step S304. If not, execute step S307.

[0077] S307. Determine whether the first sensing information is 1. If not, execute step S308. If it is, execute step S309.

[0078] S308. Control the barrier gate to close.

[0079] S309. Obtain the vehicle information of the current vehicle at the position corresponding to the first sensor.

[0080] S310. Determine whether the current vehicle has paid the fee according to the vehicle information. If it has, execute step S311. If not, execute step S308.

[0081] S311. Control the barrier gate to remain in the open state.

[0082] It should be noted that the above description of the Figure 1 parking lot anti - tailgating device in [the relevant content] also applies to the control method of this parking lot anti - tailgating device, and will not be elaborated here.

[0083] In summary, according to the control method of the parking lot anti - tailgating device in the embodiments of the present invention, first, obtain the first sensing information and the state information of the barrier gate, and determine whether the first sensor is triggered and whether the barrier gate is in the open state according to the first sensing information and the state information. That is to say, determine whether there is a vehicle at the station corresponding to the first sensor and whether the vehicle has met the exit condition and the barrier gate is open. If so, obtain the infrared sensing information, and determine whether the infrared sensor is triggered according to the infrared sensing information. If the infrared sensor is triggered, it means that there is an object at the station corresponding to the infrared sensor. At this time, obtain the second sensing information, and determine whether the second sensor is triggered according to the second sensing information. If the second sensor is triggered, it is considered that the object triggering the infrared sensor currently is a vehicle. Thus, when the second sensor is triggered, determine whether the infrared sensor changes from the triggered state to the untriggered state according to the infrared sensor information. If so, control the barrier gate to close to prevent subsequent vehicles from tailgating out of the parking lot, thereby effectively avoiding the occurrence of tailgating, improving the management and control ability of the parking lot for vehicles, and ensuring the property safety of the operator.
