Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent security, and in particular relates to an intelligent security alarm for a smart park. Background Art

[0002] In today's rapidly developing urbanization process, the park, as an important carrier of urban economic, cultural and social activities, its security issue has become the focus of attention. The construction of smart parks aims to use advanced technical means to improve the management efficiency and safety level of the park, and create a safe, comfortable and convenient environment for enterprises and residents in the park.

[0003] Although the traditional smart park security system has played a certain role in video surveillance, access control, etc., it still has many shortcomings in parking space management and security alarm. On the one hand, the existing system is often unable to accurately monitor the parking space. When the parking space is occupied without authorization, it cannot be discovered and the alarm cannot be issued in time, resulting in the owner of the parking space who was originally authorized to park in the parking space unable to use the parking space normally, affecting the parking order of the park. On the other hand, for the situation of non-standard parking of vehicles, the system lacks an effective alarm and processing mechanism, which may hinder traffic and affect the normal operation of the park. For this reason, we propose a smart security alarm for a smart park. Summary of the invention

[0004] The purpose of the present invention is to provide a smart security alarm for a smart park to solve the problem raised in the above background technology that the number of vehicles in the park is increasing, the difficulty of parking space management is increasing, and how to achieve efficient use of parking spaces, timely detect and deal with the problems of illegal occupation of parking spaces and non-standard parking of vehicles.

[0005] To achieve the above object, the present invention provides the following technical solution: a smart park intelligent security alarm, including a collection module, a registration module, a parking space monitoring module, an alarm module and a personnel terminal module, characterized in that:

[0006] The acquisition module communicates with the access control system and the monitoring system to obtain vehicle information and store it in the database. It marks the target vehicles that need to enter the park and matches the license plate numbers. It generates a release signal or a temporary parking signal based on the matching results, and registers the personnel information of the vehicles that have not been successfully matched; it assists in calculating the parking time of the target vehicle and sends it to the parking space monitoring module, and identifies the vehicle parking area at the same time;

[0007] The registration module is used for the park car owners to register their vehicle information and send the registration information to the database for storage;

[0008] The parking space monitoring module monitors the parking space usage status in the park. After receiving the temporary parking signal, it matches the target vehicle with the temporary parking space according to its characteristics and outputs the matching parking space location information. It processes non-standard parking areas and ensures that the vehicle is parked in a standardized manner through distance comparison and contour detection.

[0009] When the target vehicle does not leave the park within the parking time in the drive-away area, the alarm module generates a drive-away alarm signal and sends it to the personnel terminal module, while assisting in handling non-standard parked vehicles;

[0010] After receiving the signal from the alarm module, the personnel terminal module dispatches patrol personnel to handle the target vehicle; the most suitable patrol personnel is determined by considering the distance between the patrol personnel and the target vehicle, the task status and the transportation mode.

[0011] Preferably, the process of the acquisition module acquiring vehicle information and generating a release signal or a temporary stop signal according to the matching result is:

[0012] Vehicle information includes: license plate number, size, shape, height and owner's mobile phone number, which are sent to the database for storage;

[0013] The acquisition module marks the vehicle that needs to enter the park as a target vehicle. When the target vehicle arrives at the entrance of the park, the access control system controls the access control device to intercept the target vehicle trying to enter the park; the monitoring system controls the camera to shoot the target vehicle and capture the license plate number of the target vehicle. The acquisition module receives the license plate number of the target vehicle sent by the monitoring system and matches it with the license plate number in the vehicle information stored in the database; if the match is successful, the acquisition module generates a release signal and sends it to the detection access control system. When the access control system receives the release signal, it controls the access control device to release the target vehicle;

[0014] If the match fails, first register the mobile phone number and ID number of the person who needs to enter the park. After the registration is completed, the acquisition module generates a temporary parking signal for the target vehicle and sends it to the parking space monitoring module.

[0015] Preferably, the processing process of the parking space monitoring module after receiving the temporary parking signal is:

[0016] The target vehicle’s features are retrieved from the acquisition module, and matched with the idle temporary parking spaces in the park. The location information and number of the parking space matched by the target vehicle are output and sent to the acquisition module. After the acquisition module receives the location information of the parking space matched by the target vehicle, the location information and number of the parking space matched by the target vehicle are displayed on the access control system display screen, and the vehicle is released;

[0017] The target vehicle temporary parking space matching process is as follows:

[0018] Compare the length, width and height of the target vehicle with the dimensions of each temporary vacant parking space in the park, preset a parking matching threshold excess coefficient interval, multiply the length and width of the target vehicle by the preset parking matching threshold excess coefficient interval, obtain a temporary parking space that matches the length and width of the target vehicle, screen the temporary parking spaces that match the length and width of the target vehicle, select the temporary parking spaces whose height is greater than the height of the target vehicle, and mark them as preliminary matching parking spaces;

[0019] Get the distance MCd that the target vehicle travels to each preliminary eligible parking space, where d is the number of the parking space, d=1, ..., g, and g represents the total number of parking spaces; at the same time, extract the traffic flow value Ld of the target vehicle traveling to the area where each preliminary eligible parking space is located, using the formula: , obtain the parking space matching preference value PZd, where a1 and a2 are preset weight coefficients, select the parking space with the largest parking space matching preference value PZd as the matching parking space for the target vehicle, obtain the location information and number of the matching parking space for the target vehicle and send it to the acquisition module, where the larger the preference value PZd is, the more matching the corresponding temporary parking space is.

[0020] Preferably, the process in which the acquisition module assists in calculating the parking time of the target vehicle is:

[0021] Control the access control device to release the target vehicle, obtain the distance Hi between the target vehicle and the corresponding exclusive parking space or matching parking space, i=1,...,n; i is the number of the target vehicle, set a preset basic parking time for all vehicle types, and the vehicle types include small cars, medium-sized cars, and large cars; match the target vehicle type with all vehicle types to obtain the preset basic parking time Si corresponding to the vehicle type, and retrieve the traffic flow value Li of the vehicle leading to the corresponding exclusive parking space through the monitoring system. Use the formula: ZTi=(Si+Hi)×t1+Li×t1 to obtain the predicted total parking time ZTi of the target vehicle, where t1 is the parking time adjustment coefficient, and send the predicted total parking time ZTi of the target vehicle to the parking space monitoring module.

[0022] Preferably, the parking space monitoring module monitors the parking space usage status in the park as follows:

[0023] The parking space monitoring module starts timing to monitor whether the target vehicle is parked in the corresponding parking space within the predicted total parking time ZTi. If the target vehicle is successfully parked in the exclusive parking space within the predicted total parking time ZTi, the parking space monitoring module confirms the parking status and marks the parking space corresponding to the target vehicle as an occupied parking space;

[0024] If the vehicle fails to complete parking within the predicted total parking time ZTi, the acquisition module uses the monitoring system to identify the parking area of ​​the target vehicle based on the vehicle information of the target vehicle, and sends the parking area information of the target vehicle to the parking space monitoring module. The parking space monitoring module monitors whether the target vehicle leaves this area within the specified time.

[0025] Preferably, the process of removing the area is as follows:

[0026] After receiving the target vehicle monitoring area information sent from the acquisition module, the parking space monitoring module marks the area where the target vehicle is parked as the drive-away area, obtains the traffic flow value of the drive-away area, presets multiple temporary parking traffic flow value intervals, where each temporary parking traffic flow value interval corresponds to a temporary parking duration, matches the traffic flow value of the drive-away area with the preset multiple temporary parking traffic flow value intervals, obtains the temporary parking duration LSi corresponding to the traffic flow value of the drive-away area, and uses the formula: QTi=LSi×t2 to obtain the parking duration QTi of the drive-away area, where t2 is the parking duration adjustment coefficient;

[0027] If the target vehicle leaves the park after being parked in the drive-away area for QTi, no processing will be performed; if the target vehicle does not leave the park after being parked in the drive-away area for QTi, a target vehicle drive-away alarm signal will be generated and sent to the alarm module. After receiving the target vehicle drive-away alarm signal, the alarm module obtains the location and license plate number of the target vehicle and combines them into one message and sends it to the personnel terminal module. The personnel terminal module will dispatch inspection personnel to process the target vehicle.

[0028] Preferably, the specific process of the personnel terminal module dispatching patrol personnel to handle the target vehicle is as follows:

[0029] Assume that there are p patrol officers in the park, marked as P=1, ..., t, where t represents the total number of patrol officers; the position coordinates of each patrol officer are (Xp, Yp), and the position coordinates of the target vehicle are (Xi, Yi). Using the formula: , get the distance Dp between the inspection personnel and the target vehicle;

[0030] Set a task status variable Sp for each inspector. Sp = 0 means there is no task being processed, and Sp = 1 means there is a task being processed.

[0031] Set a speed coefficient Vpm for each patrol officer, m=1, ..., k, k represents the total number of speed coefficient types; use the formula Tpm = Dp / Vpm to obtain the time Tpm required for each patrol officer to reach the target vehicle position;

[0032] The best matching patrol personnel are determined as follows: first, the patrol personnel with task state variable Sp = 0 are screened out, and then the patrol personnel with the shortest arrival time Tpm are selected from these personnel as the best matching patrol personnel;

[0033] After determining the most matching patrol officer, the alarm module combines the location and license plate number of the target vehicle into one message and sends it to the most matching patrol officer. After receiving the message, the patrol officer immediately goes to the location of the target vehicle. After arriving at the scene, the patrol officer drives the target vehicle out of the park or guides the vehicle to the corresponding parking space. After completing the task, the patrol officer sends a task completion instruction to the parking space monitoring module. After receiving the task completion instruction, the parking space monitoring module marks the parking space corresponding to the target vehicle as occupied.

[0034] Preferably, the process of marking the parking space corresponding to the target vehicle as an occupied parking space after the parking space monitoring module confirms the parking state is as follows:

[0035] Obtain the coordinates (Xi, Yi) of the target vehicle and the coordinates (Xd, Yd) of the exclusive parking space or matching parking space corresponding to the target vehicle, and use the formula: to obtain the distance value Dip between the target vehicle and the corresponding parking space, preset the parking error threshold, and compare the distance value Dip between the target vehicle and the corresponding parking space with the preset parking error threshold. If Dip is less than the preset parking error threshold, perform parking standard detection. If Dip is less than the preset parking error threshold, it means that the target vehicle is parked in the correct parking space. If Dip is greater than the preset parking error threshold, a parking error signal is generated and sent to the alarm module. After the alarm module receives the parking error signal, it obtains the location information, license plate number, and owner's mobile phone number of the target vehicle and merges them into one message, which is sent to the personnel terminal module. After receiving the message, the personnel terminal module notifies the relevant management personnel to call the owner of the target vehicle to notify the owner to park in the corresponding exclusive parking space or matching parking space.

[0036] The outline of the target vehicle is set as a rectangle, and the coordinates of the four vertices are obtained. At the same time, the coordinates of the four vertices of the target vehicle corresponding to the exclusive parking space or the matching parking space are obtained. If all the vertices of the target vehicle are within the rectangular range surrounded by the four vertex coordinates of the parking space, the parking standard of the target vehicle is determined. At this time, the parking space monitoring module confirms the parking status and marks the parking space where the target vehicle is parked as an occupied parking space. Otherwise, it is determined that the parking of the target vehicle is not standard. The parking space monitoring module generates a non-standard parking signal and sends it to the alarm module. After the alarm module receives the non-standard parking signal, it obtains the location information, license plate number, and owner's mobile phone number of the target vehicle and merges them into one message, which is sent to the personnel terminal module. After receiving the information, the personnel terminal module notifies the relevant management personnel to call the owner of the target vehicle to notify the owner to park correctly in the corresponding parking space.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] (1) This intelligent security alarm for a smart park can quickly obtain vehicle information and match license plate numbers through the connection of the acquisition module with the access control and monitoring system. Vehicles that are successfully matched can be quickly released and the parking time can be calculated. Vehicles that fail to match can be registered in time and a temporary parking space can be arranged by the parking space monitoring module, which greatly improves the efficiency of vehicles entering the park. At the same time, the parking space monitoring module accurately matches the idle temporary parking spaces in the park according to the characteristics of the vehicle, and selects the optimal parking space considering factors such as size, distance and traffic flow, thereby improving the rationality and efficiency of parking space allocation. The parking space monitoring module can monitor the usage status of parking spaces in the park in real time, and can accurately grasp the occupancy status of both exclusive parking spaces and temporary parking spaces; by monitoring and predicting the parking time of the target vehicle, it can timely discover vehicles that fail to complete parking within the specified time, and take corresponding measures to avoid waste and confusion of parking space resources.

[0039] (2) This intelligent security alarm for a smart park uses a parking space monitoring module to confirm the parking status in a rigorous and meticulous manner. It uses distance comparison and contour detection to accurately determine whether the vehicle is parked in the correct location and whether it meets the parking standards. If the parking is not standardized, the alarm module will notify the management staff to contact the owner to make adjustments to ensure that the vehicle is parked in a standardized manner, thereby improving the accuracy and orderliness of the park's parking space management. At the same time, measures such as the preset parking matching threshold excess coefficient interval are used to ensure the compatibility of temporary parking spaces with target vehicles, thereby avoiding parking spaces being occupied by mistake and wasting space.

[0040] (3) This kind of intelligent security alarm for a smart park, when the target vehicle has been parked in the evacuation area for a long time without leaving the park, the alarm module will promptly generate an evacuation alarm signal, and the personnel terminal module will dispatch the most suitable patrol personnel to handle it; by comprehensively considering the distance between the patrol personnel and the target vehicle, the task status and the mode of transportation, the best candidate is determined to ensure that the patrol personnel can arrive at the scene quickly to evacuate the vehicle or guide it to park, thereby improving the park's ability to handle non-standard parked vehicles, improving the park's security level, and ensuring the safety and order of the park. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Figure 1 It is a flowchart of the present invention; DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1

[0044] See also Figure 1 ,The present invention provides a smart park intelligent security alarm, including a collection module, a registration module, a database, a parking space monitoring module, an alarm module, and a personnel terminal module;

[0045] The acquisition module communicates with the access control system and monitoring system in the park to obtain vehicle information of vehicles entering and leaving the community. The vehicle information includes: license plate number, vehicle characteristics (size, shape, height, and mobile phone number of the owner), and is stored in the database;

[0046] The registration module is used for the owners of the park to register their vehicle information. The vehicle information includes the license plate number, the owner's mobile phone number, the vehicle size, the vehicle picture, and the exclusive parking space number, and is sent to the database for storage;

[0047] The parking space monitoring module monitors the usage status of parking spaces in the park through surveillance cameras. The parking spaces in the park are divided into exclusive parking spaces and temporary parking spaces;

[0048] The specific working process of the present invention is:

[0049] Step 101: Marking and intercepting target vehicles: The acquisition module marks the vehicles that need to enter the park as target vehicles. When the target vehicles arrive at the park entrance, the access control system controls the access control device to preliminarily intercept the target vehicles that attempt to enter the park.

[0050] Step 102: License plate number matching: the monitoring system controls the camera to shoot the target vehicle and capture the license plate number of the target vehicle. The acquisition module receives the license plate number of the target vehicle sent by the monitoring system and matches it with the license plate number in the vehicle information stored in the database;

[0051] Step 103: Matching success processing: If the match is successful, the acquisition module generates a release signal and sends it to the detection access control system. When the access control system receives the release signal, it controls the access control device to release the target vehicle and calculates the time required for the target vehicle to park. The specific process is as follows:

[0052] Obtain the distance Hi between the target vehicle and the corresponding exclusive parking space, i=1, ..., n; i is the target vehicle number, n is the total number of target vehicles, set a preset basic parking time for all vehicle types, and the vehicle types include small cars, medium-sized cars, and large cars; match the target vehicle type with all vehicle types to obtain the preset basic parking time Si corresponding to the vehicle type, retrieve the traffic flow value Li of the vehicle leading to the corresponding exclusive parking space through the monitoring system, and use the formula: ZTi=(Si+Hi)×t1+Li×t1 to obtain the total predicted parking time ZTi of the target vehicle, where t1 is the parking time adjustment coefficient;

[0053] Step 104: Matching failure processing: If the matching fails, first register the mobile phone number and ID number of the person who needs to enter the park. After the registration is completed, the acquisition module generates a temporary parking signal of the target vehicle and sends it to the parking space monitoring module. After the parking space monitoring module receives the temporary parking signal, it retrieves the characteristics of the target vehicle from the acquisition module, matches it with the idle temporary parking space in the park, outputs the location information of the parking space matched by the target vehicle, and sends it to the acquisition module. After the acquisition module receives the location information of the parking space matched by the target vehicle, it displays the location information and number of the parking space matched by the target vehicle on the access control system display screen, and releases it. At the same time, in the same way as above, calculate the total predicted parking time ZTi of the target vehicle;

[0054] Step 105: Parking monitoring and processing: The predicted total parking time ZTi of the target vehicle is sent to the parking space monitoring module, and the parking space monitoring module starts timing to monitor whether the target vehicle is parked in the corresponding parking space within the predicted total parking time ZTi. If the target vehicle is successfully parked in the exclusive parking space within the predicted total parking time ZTi, the parking space monitoring module confirms the parking status and marks the parking space corresponding to the target vehicle as an occupied parking space;

[0055] If the vehicle fails to complete parking within the predicted total parking time ZTi, the acquisition module uses the monitoring system to identify the parking area of ​​the target vehicle based on the vehicle information of the target vehicle, and sends the parking area information of the target vehicle to the parking space monitoring module, which monitors whether the target vehicle leaves this area within the specified time;

[0056] Step 106: driving away area processing: after receiving the target vehicle monitoring area information sent from the acquisition module, the parking space monitoring module marks the area where the target vehicle is parked as the driving away area, obtains the traffic flow value of the driving away area, presets a plurality of temporary parking traffic flow value intervals, wherein each temporary parking traffic flow value interval corresponds to a temporary parking duration, matches the traffic flow value of the driving away area with the preset plurality of temporary parking traffic flow value intervals, obtains the temporary parking duration LSi corresponding to the traffic flow value of the driving away area, and uses the formula: QTi=LSi×t2 to obtain the parking duration QTi of the driving away area, wherein t2 is the parking duration adjustment coefficient; wherein the driving away area traffic flow value is obtained by: using the flow monitoring equipment set in the driving away area, taking the number of vehicles and pedestrians passing through the area per hour as the measurement index of the traffic flow value, that is, the traffic flow value per unit time=the number of vehicles×α+the number of pedestrians×β, wherein α and β are preset weight coefficients;

[0057] The process of matching the traffic flow value of the drive-away area with a plurality of preset temporary parking traffic flow value intervals to obtain the temporary parking duration LSi corresponding to the traffic flow value of the drive-away area is as follows:

[0058] The preset multiple temporary parking traffic flow value intervals are divided into a low temporary parking traffic flow value interval, a medium temporary parking traffic flow value interval and a high temporary parking traffic flow value interval according to the high and low traffic flow values, and each temporary parking traffic flow value interval corresponds to a temporary parking duration. The higher the temporary parking traffic flow value interval, the shorter the corresponding temporary parking duration. If the traffic flow value of the drive-away area falls within the medium temporary parking traffic flow value interval, the temporary parking duration corresponding to the traffic flow value of the drive-away area is the temporary parking duration corresponding to the medium temporary parking traffic flow value interval.

[0059] Step 107: Alarm and patrol personnel processing: If the target vehicle leaves the park after being parked in the drive-away area for QTi, no processing will be performed. If the target vehicle does not leave the park after being parked in the drive-away area for QTi, a target vehicle drive-away alarm signal is generated and sent to the alarm module. After receiving the target vehicle drive-away alarm signal, the alarm module obtains the location and license plate number of the target vehicle and combines them into one message and sends it to the personnel terminal module. The personnel terminal module will dispatch patrol personnel to process the target vehicle. The specific process of the personnel terminal module dispatching patrol personnel to process the target vehicle is as follows:

[0060] Assume that there are p patrol officers in the park, marked as P=1, ..., t, where t represents the total number of patrol officers; the position coordinates of each patrol officer are (Xp, Yp), and the position coordinates of the target vehicle are (Xi, Yi). Using the formula: , get the distance Dp between the inspection personnel and the target vehicle;

[0061] Determine whether the inspector has a task currently being processed, and set a task state variable Sp for each inspector. Sp = 0 means there is no task being processed, and Sp = 1 means there is a task being processed;

[0062] Set a speed coefficient Vpm for each patrol officer, m=1, ..., k, k represents the total number of speed coefficient types; for example: speed coefficient Vp1 for patrol officers on foot, speed coefficient Vp2 for patrol officers on bicycles, speed coefficient Vp3 for patrol officers driving patrol cars, etc.; use the formula Tpm = Dp / Vpm to obtain the time Tpm required for each patrol officer to reach the target vehicle position, where Vp3> Vp2> Vp1;

[0063] The best matching patrol personnel are determined as follows: first, the patrol personnel with task state variable Sp = 0 are screened out, and then the patrol personnel with the shortest arrival time Tpm are selected from these personnel as the best matching patrol personnel;

[0064] After determining the most matching patrol officer, the alarm module combines the location and license plate number of the target vehicle into one message and sends it to the most matching patrol officer. After receiving the message, the patrol officer immediately goes to the location of the target vehicle. After arriving at the scene, the patrol officer drives the target vehicle out of the park or guides the vehicle to the corresponding parking space. After completing the task, the patrol officer sends a task completion instruction to the parking space monitoring module. After receiving the task completion instruction, the parking space monitoring module marks the parking space corresponding to the target vehicle as occupied.

[0065] It should be noted that the acquisition module is connected to the access control system and the monitoring system, and can quickly and accurately obtain vehicle information, including license plate number, vehicle features, owner's facial features and mobile phone number, etc.; when a vehicle enters the park, the license plate number can be matched in time, and successfully matched vehicles can be quickly released and the parking time can be calculated. Vehicles that fail to match will be registered, and temporary parking spaces will be arranged by the parking space monitoring module, which greatly improves the efficiency of vehicles entering the park; at the same time, by detecting whether the target vehicle has completed parking within the predicted total parking time, if not, the parking time will be adjusted according to the traffic flow of the target vehicle parking area and the temporary parking time and parking time. The coefficient can be used to analyze the temporary parking time of the target vehicle in this area; this design is intended to allow the situation of sending people to the park or entering the park to pick up people in a short time; however, when the stay time exceeds the allowed parking time and may affect the traffic in the park, the alarm module will generate an expulsion alarm signal and send it to the personnel terminal; the personnel terminal will comprehensively consider factors such as the distance between the patrol personnel and the target vehicle, the transportation method of the patrol personnel, and whether the patrol personnel has a task arrangement, and determine the patrol personnel who can quickly reach the location of the target vehicle to drive away or guide the vehicle to park, thereby improving the park's ability to handle non-standard parked vehicles and improving the park's security level.

[0066] Embodiment 2

[0067] Step 201: The acquisition module generates a temporary parking signal of the target vehicle and sends it to the parking space monitoring module. After receiving the temporary parking signal, the parking space monitoring module retrieves the characteristics of the target vehicle from the acquisition module, matches it with the idle temporary parking space in the park, and outputs the location information of the target vehicle matching the parking space. The specific process is as follows:

[0068] After receiving the temporary parking signal, the parking space monitoring module retrieves the characteristics of the target vehicle from the database, compares the length, width and height of the target vehicle with the sizes of each temporary vacant parking space in the park, presets the parking matching threshold excess coefficient interval, and multiplies the length and width of the target vehicle by the preset parking matching threshold excess coefficient interval to obtain a temporary parking space that matches the length and width of the target vehicle; for example, the preset parking matching threshold excess coefficient interval is (1.1, 1.3), and the length and width of the target vehicle are multiplied by the preset parking matching threshold excess coefficient interval to obtain a temporary parking space that exceeds the length and width of the target vehicle by 10% to 30%;

[0069] Screen the temporary parking spaces that match the length and width of the target vehicle, select the temporary parking spaces whose height is greater than the height of the target vehicle, and mark them as preliminary eligible parking spaces;

[0070] Get the distance MCd that the target vehicle travels to each preliminary eligible parking space, where d is the number of the parking space, d=1, ..., g, and g represents the total number of parking spaces; at the same time, extract the traffic flow value Ld of the target vehicle traveling to the area where each preliminary eligible parking space is located, using the formula: , obtain the parking space matching preference value PZd, where a1 and a2 are preset weight coefficients, select the parking space with the largest parking space matching preference value PZd as the matching parking space for the target vehicle, obtain the location information and number of the matching parking space for the target vehicle and send it to the acquisition module, where the larger the preference value PZd is, the more matching the corresponding temporary parking space is.

[0071] Step 202: After the parking space monitoring module confirms the parking status, the process of marking the parking space corresponding to the target vehicle as an occupied parking space is as follows:

[0072] Parking space verification: Get the coordinates of the target vehicle (Xi, Yi) and the coordinates of the exclusive parking space or matching parking space corresponding to the target vehicle (Xd, Yd), using the formula: , obtain the distance value Dip between the target vehicle and the corresponding parking space, preset a parking error threshold, compare the distance value Dip between the target vehicle and the corresponding parking space with the preset parking error threshold, if Dip is less than the preset parking error threshold, perform parking space parking standard detection, Dip is less than the preset parking error threshold, indicating that the target vehicle is parked in the correct parking space, if Dip is greater than the preset parking error threshold, then generate a parking error signal and send it to the alarm module, after the alarm module receives the parking error signal, it obtains the location information, license plate number, and owner's mobile phone number of the target vehicle and merges them into one message, and sends it to the personnel terminal module, after receiving the information, the personnel terminal module notifies the relevant management personnel to call the target vehicle owner to notify the owner to park in the corresponding exclusive parking space or matching parking space;

[0073] Parking standard detection: Set the outline of the target vehicle as a rectangle, obtain the coordinates of the four vertices, and at the same time obtain the four vertex coordinates of the target vehicle's corresponding exclusive parking space or matching parking space. If all the vertices of the target vehicle are within the rectangular range surrounded by the four vertex coordinates of the parking space, the parking standard of the target vehicle is determined. At this time, the parking space monitoring module confirms the parking status and marks the parking space where the target vehicle is parked as an occupied parking space. Otherwise, it is determined that the target vehicle is parked non-standardly. The parking space monitoring module generates a non-standard parking signal and sends it to the alarm module. After the alarm module receives the non-standard parking signal, it obtains the target vehicle's location information, license plate number, and owner's mobile phone number and merges them into one message, which is sent to the personnel terminal module. After receiving the information, the personnel terminal module notifies the relevant management personnel to call the owner of the target vehicle to notify the owner so that the owner can park correctly in the corresponding parking space.

[0074] It should be noted that after receiving the temporary parking signal of the target vehicle generated by the acquisition module, the parking space monitoring module compares the size of the target vehicle with the temporary vacant parking spaces in the park, and uses the preset parking matching threshold coefficient interval to screen out temporary parking spaces that meet the length and width requirements. Then, the parking spaces with a height greater than the height of the target vehicle are further selected and marked as preliminarily eligible parking spaces. Then, the distance traveled by the target vehicle to each preliminarily eligible parking space and the traffic flow value of the area are comprehensively considered, and the parking space matching optimization value is calculated using the formula. Finally, the parking space with the largest optimization value is selected as the matching parking space for the target vehicle, thereby improving the allocation of temporary parking spaces. Reasonableness and efficiency; The parking space monitoring module is rigorous and meticulous in confirming the parking status. Through parking space verification, it uses a formula to calculate the distance between the target vehicle and the corresponding parking space, and compares it with the preset parking error threshold, so as to accurately determine whether the target vehicle is parked in the correct position; if the distance value is less than the threshold, the parking space parking standard detection is performed, the outline of the target vehicle is approximated as a rectangle and compared with the rectangular range of the parking space to determine whether the parking is standard; if the parking is not standard, the alarm module will send relevant information to the personnel terminal module, notify the management personnel to contact the owner for adjustment, ensure the vehicle parking specifications, and improve the accuracy and orderliness of the park parking space management.
