Description

Technical Field

[0001] This application relates to, but is not limited to, the field of computer technology, and in particular to a cross-regional event early warning method, device, equipment, and medium. Background Technology

[0002] Cycling races, car races, motorcycle races, and marathon races are all sporting events with a large number of participants. During the race, the entire event is monitored by video surveillance. However, due to the large number of participants at the race site, as well as factors such as lighting and weather conditions, the usable information provided by the video surveillance images is limited. Therefore, the video surveillance images alone cannot accurately identify situations where relevant personnel (such as participants or accompanying personnel) leave the race site without authorization, thus affecting the order of the race. Summary of the Invention

[0003] This application provides a cross-regional event early warning method, device, equipment, and medium that can accurately identify personnel who leave the competition venue without authorization during the competition and issue early warnings, effectively ensuring the order of the event.

[0004] In a first aspect, embodiments of this application provide a cross-regional event early warning method applied to an early warning system. The early warning system includes multiple early warning devices and multiple regional checkpoints. The system has a pre-set list of participants and multiple competition areas. The list of participants includes information on multiple participants. The regional checkpoints are located at the boundary between two adjacent competition areas. Each early warning device is equipped with a RIFD transmitter and a BeiDou positioning device. Each early warning device is uniquely bound to one participant's information. Each regional checkpoint is equipped with a RIFD receiver. The method includes:

[0005] The early warning device that is in an active state is identified as the target device, and the real-time location of each target device is determined based on each of the Beidou positioning devices.

[0006] The checkpoint corresponding to the RIFD receiver that first detects the RFID signal is determined as the target checkpoint, and the competition path between the two competition areas corresponding to the target checkpoint is determined as the target path.

[0007] The contestant information corresponding to the target device corresponding to the RFID signal obtained at the target checkpoint is determined as the contestant information that has crossed the finish line;

[0008] In the target path, the target device whose real-time position is last and which is in a moving state is identified as the calibration device;

[0009] When the over-line contestant information corresponding to the calibration device is acquired at the target checkpoint, and all the acquired over-line contestant information does not completely match all the contestant information, a first early warning prompt information is generated.

[0010] In some embodiments, the two adjacent competition areas corresponding to the target detection point are a first area and a second area, the path direction of the target path is the direction of a line connecting a position point of the first area, the target detection point and a position point of the second area in sequence, the target device whose real-time position is at the last position and in a moving state is determined as the calibration device, and the method comprises:

[0011] determining a reference position in all the real-time positions of the devices located in the first area;

[0012] determining a reference distance between each reference position and the target checkpoint;

[0013] determining the reference position corresponding to the reference distance with the largest value in all the reference distances as the calibration device corresponding to the target device.

[0014] In some embodiments, the number of contestant information in the contestant list is a target number, when the over-line contestant information corresponding to the calibration device is acquired at the target checkpoint, and all the acquired over-line contestant information does not completely match all the contestant information, a first early warning prompt information is generated, and the method comprises:

[0015] matching each over-line contestant information currently acquired at the target checkpoint with each contestant information in the contestant list to determine each first matching result;

[0016] determining a reference number of over-line contestant information corresponding to the first matching result;

[0017] when the reference number is less than the target number, and all the first matching results represent a matching success, generating a first early warning prompt information according to the contestant information in the contestant list which is not matched with the over-line contestant information;

[0018] or,

[0019] when the reference number is less than the target number, and all the first matching results do not completely represent a matching success, generating a first early warning prompt information according to the contestant information in the contestant list which is not matched with the over-line contestant information and the over-line contestant information corresponding to the first matching result representing a matching failure;

[0020] Or,

[0021] When the reference quantity is equal to the target quantity, and all the first matching results do not completely represent matching success, a first early warning prompt information is generated according to the overline player information corresponding to the first matching result representing matching failure.

[0022] In some embodiments, the area checkpoint is further provided with a first camera, and each of the player information is associated with a reference image. When the overline player information corresponding to the target device is acquired at the target checkpoint, and all the overline player information acquired at present does not completely match all the player information, a first early warning prompt information is generated, including:

[0023] When the target checkpoint acquires the RFID signal, the first camera is controlled to acquire a first player image;

[0024] The first player image is associated with the overline player information corresponding to the target device corresponding to the RFID signal;

[0025] The first player image associated with each of the overline player information is matched with each of the reference images to obtain each second matching result, and each second matching result is associated with the corresponding first matching result;

[0026] In the case where the reference quantity is less than the target quantity, and all the first matching results represent matching success, when the second matching result corresponding to the first matching result representing matching success represents matching failure, a first early warning prompt information is generated based on the overline player information corresponding to the second matching result representing matching failure and the player information in the player list that does not match the overline player information;

[0027] Or,

[0028] In the case where the reference quantity is less than the target quantity, and all the first matching results do not completely represent matching success, when the second matching result corresponding to any of the first matching results represents matching failure, a first early warning prompt information is generated for each of the overline player information corresponding to the first matching result representing matching failure, the player information in the player list that does not match the overline player information, and the overline player information corresponding to the second matching result representing matching failure;

[0029] Or,

[0030] In the case that the reference quantity is equal to the target quantity and all the first matching results do not completely represent matching success, when any second matching result corresponding to the first matching result represents matching failure, first early warning prompt information is generated according to the overline contestant information corresponding to the first matching result representing matching failure and the overline contestant information corresponding to the second matching result representing matching failure.

[0031] In some embodiments, the area checkpoint is further provided with a first camera, and each of the contestant information is associated with a reference image. When the overline contestant information corresponding to the target device is acquired at the target checkpoint, and all the overline contestant information acquired at present does not completely match all the contestant information, first early warning prompt information is generated, including:

[0032] controlling the first camera to acquire a second contestant image in real time;

[0033] matching the second contestant image with all the reference images to obtain each third matching result, monitoring whether any RFID signal of the target device is acquired at the target checkpoint at present to obtain a first monitoring result corresponding to each third matching result, and monitoring whether any Beidou positioning signal of the target device is detected at the target checkpoint at present to obtain a second monitoring result;

[0034] when any third matching result represents matching success, regardless of whether the first monitoring result corresponding thereto represents that the RFID signal of the corresponding target device is acquired at the target checkpoint at present, and regardless of whether the second monitoring result corresponding thereto represents that the Beidou positioning signal of the corresponding target device is acquired at the target checkpoint at present, the contestant information associated with the reference image matched with the second contestant image is marked as first exceptional contestant information, and no early warning prompt operation is triggered;

[0035] in the case that any third matching result represents matching failure, when the first monitoring result corresponding thereto represents that the RFID signal of the corresponding target device is acquired, or the second monitoring result corresponding thereto represents that the Beidou positioning signal of the corresponding target device is acquired, the contestant information associated with the reference image matched with the second contestant image is marked as second exceptional contestant information, and no early warning prompt operation is triggered;

[0036] when the third contestant image acquired by the first camera does not match all the reference images, and the first monitoring result corresponding thereto represents that the RFID signal of the corresponding target device is not acquired, and the second monitoring result corresponding thereto represents that the Beidou positioning signal of the corresponding target device is not acquired, the first early warning prompt information is generated according to the third contestant image and the monitoring result.

[0037] In some embodiments, each of the contestant information is associated with a companion account, after marking the contestant information associated with the reference image matched with the second contestant image as exceptional contestant information, the method further comprises:

[0038] detecting an exceptional real-time location of a target device corresponding to the exceptional contestant information;

[0039] generating a device supply prompt information based on the exceptional real-time location and the exceptional contestant information;

[0040] sending the device supply prompt information to the companion account associated with the exceptional contestant information.

[0044] generating a second early warning prompt information when the getting-on personnel image does not match the getting-off personnel image.

[0048] This application provides a cross-regional event early warning method, device, equipment, and medium. The method includes: identifying the early warning device in an active state as a target device; determining the real-time location of each target device based on each BeiDou positioning device; identifying the area checkpoint corresponding to the RIFD receiver that first detects an RFID signal as a target checkpoint; identifying the competition path between the two competition areas corresponding to the target checkpoint as a target path; identifying the participant information corresponding to the target device obtained from the RFID signal at the target checkpoint as the finish line participant information; identifying the target device whose real-time location is last and in a moving state as a calibration device in the target path; and generating a first early warning message when the finish line participant information corresponding to the calibration device is obtained at the target checkpoint, and the currently obtained finish line participant information does not completely match the total participant information. According to the solution provided in the embodiments of this application, in cross-regional competitions, the target detection point at the border of two locations is used as a reference point. By determining the early warning device corresponding to the contestant ranked last in the current competition, and using the information of the contestant who has crossed the line obtained from the reference point as a trigger to compare all the information of the contestants who have crossed the line with the information in the preset list, an early warning is issued based on the comparison result. In this way, the availability of the information of the contestants who have crossed the line for comparison and the accuracy of the comparison result can be guaranteed. In this way, it is possible to accurately identify the personnel who leave the competition venue without authorization during the competition and issue an early warning, effectively ensuring the order of the competition.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] It is to be understood that, although functional modules are divided in the device schematic diagram, and logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in a manner different from the module division in the device or the order in the flowchart. The terms "first", "second", and the like in the specification, claims, or above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0054] Bicycle races, car races, motorcycle races, and marathons are sports events with a large number of participants. During the event, the entire event is monitored by video. However, due to the large number of participants in the competition site, the influence of on-site lighting, and weather factors, the image data obtained by video monitoring can provide less useful information. Therefore, the image data obtained by video monitoring cannot accurately identify the situation that relevant personnel (such as participants or accompanying personnel) leave the competition site during the competition, which affects the order of the event.

[0055] To solve the above-mentioned problems, the embodiments of the present application provide a cross-regional event early warning method, device, equipment, and medium. The method comprises the following steps: determining a pre-warning device in an activated state as a target device, determining the real-time position of each target device based on each Beidou positioning device; determining the area checkpoint corresponding to the RFID receiver that first detects an RFID signal as a target checkpoint, and determining the competition path between the two competition areas corresponding to the target checkpoint as a target path; determining the participant information corresponding to the target device corresponding to the RFID signal obtained by the target checkpoint as over-line participant information; in the target path, determining the target device located at the last position and in a moving state as a calibration device; when the over-line participant information corresponding to the calibration device is obtained at the target checkpoint, and the current obtained all over-line participant information does not completely match all participant information, a first early warning prompt information is generated. According to the scheme provided by the embodiments of the present application, in a cross-regional event, the target detection point at the junction of two places is taken as a reference point, the pre-warning device corresponding to the participant ranked at the last position in the current event is determined, and the over-line participant information of the pre-warning device obtained at the reference point is taken as a trigger for comparing the current received all over-line participant information with the information in the preset list. The comparison result is used for early warning. In this way, the availability of the over-line participant information used for comparison operation and the accuracy of the comparison result can be ensured, and the personnel who leave the competition site during the competition can be accurately determined and early warning can be performed, thereby effectively ensuring the order of the event.

[0056] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0057] Reference Figure 1 , Figure 1 is a step flow chart of a cross-regional event early warning method provided by an embodiment of the application. The embodiment of the application provides a cross-regional event early warning method. The method is applied to an early warning system. The early warning system includes a plurality of early warning devices and a plurality of regional checkpoints. The early warning system is preset with a list of participants and a plurality of competition regions. The list of participants includes a plurality of participant information. The regional checkpoints are located at the junction of two adjacent competition regions. The early warning devices are provided with RIFD transmitters and Beidou positioning devices. The early warning devices are uniquely bound to one participant information. The regional checkpoints are installed with RIFD receivers. The method includes but is not limited to the following steps:

[0058] Step S10, determining the early warning devices in the active state as target devices, and determining the real-time positions of the target devices based on the Beidou positioning devices.

[0059] Specifically, the early warning devices in the embodiment are wristbands worn by the participants or tracking locators and identity identifiers installed on the racing tools (such as bicycles, cars or motorcycles) of the participants, which can help the event organizers accurately locate the participants and track the riding tracks of the participants.

[0060] Specifically, the early warning devices in the active state are the early warning devices in the powered-on state that enter the signal range of the competition regions. According to the description of the above embodiment, since the early warning devices are the tracking locators closely connected to the participants, the tracking locators in the active state can provide effective support for monitoring the positions and action tracks of the participants.

[0061] Specifically, the Beidou positioning device of each early warning device in the embodiment is used to facilitate the system to obtain the real-time positions of the corresponding participants in real time, to determine the participant ranking last in the current competition, and to further determine when to trigger the operation of comparing the participant information (such as the RFID signal) currently collected with the information in the list of participants. Those skilled in the art can also use a GPS device instead of the Beidou positioning device, which can achieve the real-time position information of the target devices in the active state.

[0062] Step S20, determining the regional checkpoint corresponding to the RIFD receiver that first detects the RFID signal as a target checkpoint, and determining the competition path between the two competition regions corresponding to the target checkpoint as a target path.

[0063] Specifically, the regional checkpoint of the embodiment is located at the junction of two adjacent competition areas, the competition venue is divided into multiple competition areas, for example, the competition spans city A and city B, a regional checkpoint is set at the junction of the two cities, or according to the preset area range of the competition venue, for example, in the competition venue, a regional checkpoint is set every preset distance (i.e. the pass race course), so that the position monitoring and identity recognition verification of the participating players can be realized multiple times during the competition, and the participating players leaving the competition venue without authorization can be more effectively avoided. Figure 2 The competition area 1 and the competition area 2 are two adjacent competition areas in the multiple competition areas of the competition of the embodiment, and there is a regional checkpoint between the competition area 1 and the competition area 2. The target device 1, …, the target device n in the embodiment correspond to the participating players ranked in the current competition in order, the target device 1 corresponds to the participating player ranked first in the current competition, when the regional checkpoint located between the competition area 1 and the competition area 2 detects the RFID signal for the first time, i.e. the target device 1 passes through the regional checkpoint, after the RIFD receiver of the regional checkpoint detects the RFID signal emitted by the target device 1, the regional checkpoint is determined as the target checkpoint, and the competition path between the two competition areas corresponding to the target checkpoint is determined as the target path, the target checkpoint triggers to record the RFID signal of each passing target device, so that the identity recognition and tracking positioning of each early warning device detected in the competition area 1 before entering the competition area 2 can be realized, thereby providing an effective data basis for subsequent determination of the location of the calibration device of the participating player ranked last and comparison with the information in the participating player list.

[0064] Specifically, each regional checkpoint of the embodiment is a pass base station, and the RFID transmitter in the early warning device has a unique code. When the participating player passes through the regional checkpoint, the RFID receiver of the regional checkpoint reads the unique code to detect the RFID signal, and quickly identifies and records the identity of the participating player.

[0065] Step S30, the participating player information corresponding to the target device corresponding to the RFID signal obtained by the target checkpoint is determined as the over-the-line player information.

[0066] Step S40, in the target path, the target device whose real-time position is in the last position and is in a moving state is determined as the calibration device.

[0067] Specifically, as shown in Figure 2As shown, in the current competition, the contestants are passing through the target path between competition area 1 and competition area 2. In this embodiment, the calibration device is the early warning device corresponding to the contestant ranked last in the current target path. It can be understood that the comparison operation between the currently collected information of contestants who have crossed the line and the information in the contestant list, as well as the subsequent early warning operation for contestant information with abnormal comparison results, are performed once for each segment of the race path corresponding to each area checkpoint. Moreover, the execution of these two operations is only meaningful after the contestant ranked last in the current race passes through the target checkpoint of the current segment and the information of the contestant who has crossed the line corresponding to the calibration device is collected. Otherwise, it is impossible to determine which contestant has missed or which early warning device is abnormal. Therefore, in this embodiment, after the area checkpoint at the junction of the current competition area 1 and competition area 2 is marked as the target checkpoint, the GPS device of each target device determines the target device whose real-time position is last in the target path and is in a moving state. The device is marked as the calibration device and the calibration device is monitored in real time, so as to determine when the information comparison operation of step S50 is triggered.

[0068] Specifically, in this embodiment, the first detection of an RFID signal at a regional checkpoint located at the boundary of two adjacent competition areas is used as the trigger condition. After the regional checkpoint detects an RFID signal for the first time, the regional checkpoint is marked as a target checkpoint. The RFID signals passing through the target checkpoint are recorded in sequence, and the information of the athletes crossing the line for each RFID signal is determined. This provides an effective data basis for the information comparison operation in step S50 when the target checkpoint collects the information of athletes crossing the line from the calibration device.

[0069] Specifically, in some embodiments, the two adjacent competition areas corresponding to the target detection point are the first area and the second area, and the path direction of the target path is the direction of the line connecting the position points of the first area, the target detection point, and the position points of the second area in sequence. Figure 1 Step S40 includes, but is not limited to, the following steps:

[0070] Step S41: Determine the location in the first region from all real-time device locations as the reference location;

[0071] Step S42: Determine the reference distances between each reference position and the target checkpoint;

[0072] Step S43: Among all the reference distances, the reference position corresponding to the reference distance with the largest value is identified as the calibration device.

[0073] It is understood that this embodiment determines the location in the first region among all real-time device locations as the reference location, determines each reference location and each reference distance between the reference location and the target check point, and determines the target device corresponding to the reference distance with the largest value among all reference distances as the calibration device, thereby providing an effective data basis for determining when to trigger the information comparison operation of step S50.

[0074] Additionally, it should be noted that when a participant withdraws during the competition, accompanying personnel use an RFID handheld device to scan the withdrawing participant's wristband and upload the information to confirm the withdrawal. This updates the participant list in real time and removes all information about the withdrawing participant from the list. Thus, when updating the participant list, this embodiment re-executes steps S41 to S43 to recalibrate the device, effectively ensuring the accuracy of information comparison results and early warnings in exceptional circumstances.

[0075] Step S50: When the information of the contestants who have crossed the line corresponding to the calibration device is obtained at the target checkpoint, and the information of all the contestants who have crossed the line obtained at this time does not completely match the information of all the contestants, a first warning message is generated.

[0076] Specifically, in this embodiment, the information format of the contestant information and the information of the contestants who crossed the finish line is the same, corresponding to the information of the RFID signal. By matching whether the contents are the same, it can be determined whether there is an anomaly in the race path corresponding to the current target checkpoint. It can be understood that when the information of the contestants who crossed the finish line corresponding to the calibration device is obtained at the target checkpoint, it triggers the comparison and matching of all the information of the contestants who crossed the finish line collected at the current target checkpoint with all the information of the contestants in the contestant list. If the information of all the contestants who crossed the finish line obtained at the current time does not completely match the information of all the contestants, it indicates that there is a risk that the contestants have left the competition venue without authorization. At this time, the first warning message is generated to effectively ensure the order of the event.

[0077] Specifically, situations where the information on all qualified players does not completely match the information on all participants include situations where the number of qualified players is greater than the number of participants in the list of participants, or the number of qualified players is less than the number of participants in the list of participants, or the content of the qualified players' information partially or entirely does not match the content of the participants' information in the list of participants.

[0078] Specifically, the number of target checkpoints in this application embodiment is determined by the actual cycling speed of the participants. When there are multiple target checkpoints, each target checkpoint will trigger an operation to compare the information of the participants who have crossed the line collected by the current target checkpoint with the information in the list of participants after detecting the information of the participants who have crossed the line from the calibration device. Since each target checkpoint is located at the boundary of two adjacent competition areas, that is to say, every time the current participant passes through a section of the race route, a warning check will be carried out on all the participants in the current race, so as to accurately identify the personnel who leave the race site without authorization during the race and issue a warning, effectively ensuring the order of the event.

[0079] Specifically, in some embodiments, the number of contestant information entries in the contestant list is a target number. Figure 1 Step S50 includes, but is not limited to, the following steps:

[0080] Step S501: Match the information of each cross-line contestant currently obtained at the target checkpoint with the information of each contestant in the contestant list to determine each first matching result;

[0081] Step S502: Determine the reference number of qualified players' information corresponding to the first matching result;

[0082] Step S503: When the number of references is less than the target number, and all the first matching results indicate successful matching, generate the first warning message based on the information of the contestants in the contestant list that does not match the information of the contestants who passed the line.

[0083] or,

[0084] Step S504: When the number of references is less than the target number, and all the first matching results do not completely represent successful matching, generate a first warning message based on the contestant information in the contestant list that does not match the information of qualified contestants and the qualified contestant information corresponding to the first matching results that represent failed matching.

[0085] or,

[0086] Step S505: When the reference number equals the target number, and all the first matching results do not completely represent successful matching, generate the first warning message based on the information of the qualified players corresponding to the first matching results that represent failed matching.

[0087] Specifically, the first matching result in this embodiment is the result of matching the information of each qualified player currently obtained at the target checkpoint with the information of all the qualified players in the list of qualified players. The first matching result includes two cases: successful matching and failed matching. When the first matching result indicates successful matching, it means that the qualified player corresponding to the matching source information (i.e. the qualified player information) is normal. When the first matching result indicates failed matching, it means that the qualified player corresponding to the matching source information (i.e. the qualified player information) is abnormal.

[0088] It is understandable that, referring to the description of the above embodiments, since the operation of comparing the information of the qualified contestants with the information of the contestant list is triggered by the qualified contestant information of the calibration device corresponding to the last ranked contestant detected by the current target checkpoint, this embodiment compares the reference number of the first matching result representing a successful match with the number of contestant information in the contestant list (i.e., the target number). When the reference number is different from the target number, for example, when the reference number is less than the target number, it is necessary to issue an early warning based on the specific information of the first matching result. The early warning method of this embodiment includes: (1) when the reference number is less than the target number, and all the first matching results represent a successful match, it indicates that the contestant information corresponding to the contestant information in the contestant list that does not match the qualified contestant information has the risk of leaving the competition venue without authorization. (1) The first warning message is generated based on the information of the contestants whose hand information is matched with the target number; (2) When the reference number is equal to the target number, and all the first matching results do not completely indicate a successful match, it means that the contestants whose information does not match the information of the qualified contestants in the contestant list and the contestants whose information of the qualified contestants indicates a failed match are at risk of leaving the competition venue without authorization. The first warning message is generated based on the information of the contestants whose information does not match the information of the qualified contestants in the contestant list and the qualified contestants whose information of the first matching results indicates a failed match; (3) When the reference number is equal to the target number, and all the first matching results do not completely indicate a successful match, it means that the contestants whose information of the qualified contestants indicates a failed match are at risk of leaving the competition venue without authorization. The first warning message is generated based on the qualified contestants whose information of the first matching results indicates a failed match. According to the warning scheme of this application, the target personnel who leave the competition venue without authorization can be accurately identified from multiple aspects, thereby effectively ensuring the order of the event.

[0089] Specifically, in some embodiments, the area checkpoints are also equipped with a first camera, and each contestant's information is associated with a reference image. Figure 1 Step S50 includes, but is not limited to, the following steps:

[0090] Step S504: When the target checkpoint receives an RFID signal, control the first camera to acquire an image of the first contestant;

[0091] Step S505: Associate the first contestant's image with the information of the contestant who crossed the finish line corresponding to the target device corresponding to the RFID signal;

[0092] Step S506: Match the first contestant image associated with each contestant who has passed the finish line with each reference image to obtain each second matching result, and associate each second matching result with the corresponding first matching result;

[0093] Step S507: When the reference number is less than the target number and all the first matching results indicate successful matching, when the second matching result corresponding to the first matching result indicating successful matching indicates failed matching, a first warning message is generated based on the qualifying player information corresponding to the second matching result indicating failed matching and the information of the participating players in the list of participating players that does not match the qualifying player information.

[0094] or,

[0095] Step S508: When the number of references is less than the target number and all the first matching results do not completely represent successful matching, when the second matching result corresponding to any first matching result represents a failed match, generate a first warning message for each participant information that does not match the qualifying participant information in the participant list, the qualifying participant information corresponding to the first matching result representing a failed match, and the qualifying participant information corresponding to the second matching result representing a failed match.

[0096] or,

[0097] Step S509: When the reference number equals the target number and all the first matching results do not completely represent successful matching, when the second matching result corresponding to any first matching result represents a failed matching, a first warning message is generated based on the qualifying player information corresponding to the first matching result representing a failed matching and the qualifying player information corresponding to the second matching result representing a failed matching.

[0098] Specifically, the second matching result in this embodiment is the matching result between the first contestant image associated with each contestant information that has passed the line obtained at the target checkpoint and the corresponding reference image in the contestant list. The second matching result includes two cases: successful matching and failed matching. When the second matching result indicates successful matching, it means that the contestant corresponding to the matching source information (i.e., the corresponding contestant information that has passed the line) is normal. When the second matching result indicates failed matching, it means that the contestant corresponding to the matching source information (i.e., the corresponding contestant information that has passed the line) is abnormal.

[0099] Understandably, in order to more accurately identify and protect participants who leave the competition venue without authorization during the event, as well as to ensure the accuracy of early warnings and maintain the order of the event, this embodiment performs identity verification checks on each participant at each area checkpoint. In addition to using RFID technology, it also uses facial image recognition technology, combining the two to detect whether the information of the participants who pass through the target checkpoint is consistent with the information of the participants in the participant list.

[0100] Specifically, in this embodiment, the acquisition of RFID signals at the target checkpoint is used as the trigger condition for capturing contestant images. Each time a first contestant image is captured, the first contestant image is associated with the information of the contestant who crossed the finish line corresponding to the target device corresponding to the RFID signal, providing an effective data foundation for subsequent information matching and image matching operations.

[0101] It is understood that in this embodiment, if any one of the following three conditions is not met—that is, the reference number is different from the target number, and / or the first matching result indicates that the information of the qualified contestant has failed to match with the information of each contestant, and / or the second matching result indicates that the image of the first contestant has failed to match with the corresponding reference image—it is considered that there is an anomaly, and a first warning message is generated accordingly. The specific warning scheme is as follows: (1) When the reference number is less than the target number and all the first matching results indicate that the match is successful, when the second matching result corresponding to the first matching result indicating that the match is successful indicates that the match is unsuccessful, a first warning message is generated based on the information of the qualified contestant corresponding to the second matching result indicating that the match is unsuccessful and the information of the contestants in the contestant list that does not match the information of the qualified contestant. (2) When the reference number is less than the target number and all the first matching results do not completely represent successful matching, when the second matching result corresponding to any first matching result represents a failed match, a first warning message is generated for each participant information that does not match the qualifying participant information in the participant list, the qualifying participant information corresponding to the first matching result representing a failed match, and the qualifying participant information corresponding to the second matching result representing a failed match; (3) When the reference number is equal to the target number and all the first matching results do not completely represent successful matching, when the second matching result corresponding to any first matching result represents a failed match, a first warning message is generated based on the qualifying participant information corresponding to the first matching result representing a failed match and the qualifying participant information corresponding to the second matching result representing a failed match.

[0102] In addition, this embodiment also discloses a scheme for acquiring images of personnel passing through the target checkpoint in real time using a first camera. After the information of the contestants crossing the line from the calibration device is acquired at the target checkpoint, not only is the RFID identification and matching scheme described in the embodiment of steps S501 to S505 triggered, but also all personnel images identified at the target checkpoint are matched one by one with the reference images associated with the contestant information. When the reference number of the first matching result is less than or equal to the target number, the number of personnel images detected by the first camera is more than the reference number. This embodiment generates a third warning message based on the personnel images that fail to match with the reference images, which can accurately identify the situation where non-contestants have entered the competition venue and issue a warning.

[0103] Specifically, in some embodiments, the area checkpoints are also equipped with a first camera, and each contestant's information is associated with a reference image. Figure 1 Step S50 includes, but is not limited to, the following steps:

[0104] Step S510: Control the first camera to acquire images of the second contestant in real time;

[0105] Step S511: Match the second contestant image with all reference images to obtain each third matching result; monitor whether the current target detection point has obtained the RFID signal of any target device to obtain the first monitoring result corresponding to each third matching result; and monitor whether the current target detection point has detected the Beidou positioning signal of any target device to obtain the second monitoring result.

[0106] Step S512: When any third matching result indicates a successful match, regardless of whether the corresponding first monitoring result indicates that the current target detection point has obtained the RFID signal of the corresponding target device, and regardless of whether the corresponding second monitoring result indicates that the current target detection point has obtained the Beidou positioning signal of the corresponding target device, the contestant information associated with the reference image that matches the second contestant image is marked as the first exceptional contestant information, and no warning prompt operation is triggered.

[0107] Step S513: If any of the third matching results fails to match, when the corresponding first monitoring result obtains the RFID signal of the corresponding target device, or the corresponding second monitoring result obtains the Beidou positioning signal of the corresponding target device, the contestant information associated with the reference image that matches the second contestant image is marked as the second exceptional contestant information, and no warning prompt operation is triggered.

[0108] Step S514: When the first camera acquires a third contestant image that does not match any of the reference images, and the corresponding first monitoring result indicates that the RFID signal of the corresponding target device has not been acquired, and the corresponding second monitoring result indicates that the Beidou positioning signal of the corresponding target device has not been acquired, a first warning message is generated based on the third contestant image and the monitoring results.

[0109] Understandably, considering that during the competition, the warning devices worn by contestants may fail to detect RFID signals at checkpoints due to drops, impacts, or other reasons, this embodiment prioritizes the third matching result corresponding to image matching as a highly weighted factor to prevent the contestant from being considered an abnormal contestant when passing through the target checkpoint. If any third matching result indicates a successful match, and the corresponding monitoring result indicates that the current target detection point has not obtained the RFID signal of the target device corresponding to the contestant information associated with the reference image matching the second contestant's image, the contestant information associated with the reference image matching the second contestant's image is marked as first-class abnormal contestant information, and no warning prompt is triggered; when the first camera... If the first camera acquires a third contestant image that does not match any of the reference images, it needs to combine the first and second monitoring results to determine whether to issue a warning. If either the first or second monitoring result indicates that a corresponding signal has been detected, the contestant information associated with the reference image that matches the second contestant image is marked as the second exception contestant information, and no warning prompt is triggered. If the first camera acquires a third contestant image that does not match any of the reference images, and the corresponding first monitoring result indicates that the RFID signal of the corresponding target device has not been acquired, and the corresponding second monitoring result indicates that the Beidou positioning signal of the corresponding target device has not been acquired, a first warning prompt message is generated based on the third contestant image and the monitoring results.

[0110] In addition, in some embodiments, each participant's information is associated with an accompanying person's account. After executing step S512, which marks the participant information associated with the reference image that matches the second participant's image as exceptional participant information, the cross-regional event warning method of this application embodiment also includes, but is not limited to, the following steps:

[0111] Step S5121: Detect the real-time location of the target device corresponding to the information of the exceptional contestant;

[0112] Step S5122: Generate equipment replenishment prompt information based on the exceptional real-time location and exceptional player information;

[0113] Step S5123: Send the equipment replenishment notification to the accompanying personnel account associated with the exceptional player's information.

[0114] Similarly, considering that the warning devices worn by the contestants may fall off due to impacts or other reasons during the competition, this embodiment detects the real-time location of the target device corresponding to the exception contestant information, generates a device replenishment prompt based on the exception real-time location and the exception contestant information, and sends the device replenishment prompt to the accompanying personnel account associated with the exception contestant information so that the accompanying personnel can replenish the warning devices for the exception contestant in a timely manner.

[0115] In addition, in some embodiments, the early warning system also includes multiple accompanying vehicles, each equipped with a second camera and door access control device. The early warning system has multiple sets of information on accompanying personnel, each set of information on an accompanying person is uniquely associated with an accompanying vehicle, and an accompanying vehicle is associated with one or more sets of information on accompanying personnel. The cross-regional event early warning method of this application embodiment also includes, but is not limited to, the following steps:

[0116] Step S61: When the door access control device of any accompanying vehicle detects that the door is open, control the second camera to acquire the image of the person getting out of the vehicle;

[0117] Step S62: When the door access control device detects the door opening again, it controls the second camera to acquire images of the passengers boarding the vehicle.

[0118] Step S63: When the image of the person boarding the vehicle does not match the image of the person boarding the vehicle, a second warning message is generated.

[0119] It is understood that this embodiment also discloses a scheme for issuing an early warning for accompanying personnel leaving the competition venue without authorization. The specific scheme includes: installing a second camera and a door access control device inside each accompanying vehicle. When the door access control device of any accompanying vehicle detects that the door is open, it controls the second camera to acquire an image of the person getting out of the vehicle. When the door access control device detects that the door is open again, it controls the second camera to acquire an image of the person getting on the vehicle. This provides an effective data basis for detecting whether the accompanying personnel getting on and off the vehicle are consistent. When the image of the person getting on the vehicle does not match the image of the person getting on the vehicle, a second early warning message is generated.

[0120] In addition, to prevent the RFID receiver at the target checkpoint from failing, this embodiment is equipped with an RFID handheld device in power-on state as an emergency plan, and a Beidou positioning module is integrated into the early warning device. If the RFID receiver at the target checkpoint fails and the contestant's data cannot be read, the Beidou positioning data collected and transmitted by each early warning device can be received through the system backend. The system backend can analyze the position deviation. If it is within the error range, it is considered as compliant operation. If it is outside the error range, an early warning is issued.
