Description

Technical Field

[0001] The invention relates to a virtual-real electronic fence positioning system and also to a corresponding electronic fence positioning method, belonging to the technical field of security monitoring. Background Art

[0002] In the existing technology, whether it is the use of base stations to collect mobile phone communications or Wi-Fi signals or traffic audits through gateways, it is inseparable from the premise that the physical electronic fence is close to the end user. Moreover, in order to expand the coverage of the electronic fence, multiple physical electronic fences need to cooperate, so the cost is extremely high and the workload is large. If you want to portray the behavior trajectory, you need to set up collection equipment at necessary intersections and nodes. Not only does it require a huge number of hardware devices, but it also requires reasonable prediction and planning, and even a lot of deployment and implementation work. There will be many unexpected situations in actual use, resulting in positioning failure.

[0003] In the Chinese invention application with application number 201810691950.1, a method for generating an electronic fence is disclosed. The generation method includes: obtaining a set of positioning point data; evaluating the set of positioning point data based on the preset electronic fence generation conditions to obtain an evaluation result; if the evaluation result is passed, the electronic fence area is circled according to the pre-input electronic fence setting parameters; extracting the outermost shape of the electronic fence area to generate an electronic fence. In addition, in the Chinese invention application with application number 201811520689.5, a method and system for detecting automobile electronic fences based on V2X is also disclosed. In this method, the electronic fence area of ​​the vehicle corresponding to the user ID is first set; the server sends the electronic fence area to the vehicle positioning terminal of the vehicle corresponding to the user ID through V2X, and the vehicle positioning terminal generates an electronic fence map according to the electronic fence area; the real-time positioning information of the vehicle is obtained, and it is determined whether the position of the vehicle is within the area defined by the electronic fence map.

[0004] However, the prior art only generates an electronic fence based on multiple positioning points; or only determines whether a positioning point falls into a predetermined electronic fence area. The prior art cannot automatically generate an electronic fence based on a single point, nor can it automatically generate an electronic fence based on terrain, and it cannot determine the accurate position of a positioning target (such as a human body or a vehicle) in real time and reliably based on the automatically generated electronic fence combined with the physical electronic fence. Summary of the invention

[0038] The technical content of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] like Figure 1 and Figure 2 As shown, the electronic fence positioning system provided by the embodiment of the present invention includes a background system (usually implemented by a cloud server), multiple virtual electronic fences and physical electronic fences. Each virtual electronic fence and / or physical electronic fence communicates with the cloud server to exchange information collected by the virtual electronic fence and / or physical electronic fence on the terminal (including but not limited to smart phones, personal computers, tablet computers and other electronic devices with Internet access).

[0040] In an embodiment of the present invention, the physical electronic fence includes physical devices such as terminal code detection equipment, Wi-Fi probes and network audit equipment with positioning data collection and reporting functions. Among them, the terminal code detection equipment is an active terminal code detection equipment, which is based on the working principle of wireless communication base stations and Wi-Fi networks, and uses the uniqueness of terminal serial codes to achieve ultra-high-speed feature code IMSI information and MAC address collection, and delimit the mobile range of the terminal. The collection equipment has the technical characteristics of small size, high intelligence, easy maintenance and customized background system function management, and is a fast and effective high-tech investigation equipment. Wi-Fi probes, such as mobile phone electronic fence equipment, simulate the broadcast induction signal of the operator's mobile communication network (Mobile / Unicom / Telecom), so that the terminals in the surrounding standby state (hereinafter taking smart phones as an example) detect changes in the location area, thereby initiating a location area update request, registering, registering, and reporting IMEI information / IMSI information to the mobile phone electronic fence equipment, so as to complete the collection of public network user terminal information in the coverage area, and then transmit the collected IMSI information or IMEI information to the data management system center of the background system in real time through wired or wireless backhaul. Wi-Fi probes can collect mobile phone MAC addresses, support the identification and cleaning of fake MACs, and can transmit data using certificate authentication via the https protocol.

[0041] Physical electronic fences are used to directly collect legal information from unknown users who have not installed the pre-determined mobile client. To use physical electronic fences, you need to enter your account, password, and ID number in the background system, and the account is bound to the physical electronic fence, so others cannot log in on other devices. Physical electronic fences can only collect data after being authorized by the background system. The background system saves records of each data collected by the physical electronic fence (including the time and location of the data). All records of the use of physical electronic fences to obtain data are transmitted to relevant departments to ensure that the data collection behavior is legal.

[0042] The virtual electronic fence obtains data from the terminal's Internet data, Internet database, private database, etc., and sends it to the background system. The virtual electronic fence is based on the systems and data resources built by relevant departments (such as technical investigation, network security intelligence and other functional departments), integrates various other data resources and social data resources, forms a multi-source data fusion center, and relies on relevant websites in various places to build a set of relevant intelligence analysis platforms to achieve the interconnection and complementarity of data and platforms, and at the same time build the correlation sharing and linkage application of data resources and intelligence information between upper and lower levels.

[0043] Under the deployment of relevant departments, the virtual electronic fence directly collects legal information from users who install the predetermined mobile client. In addition, under the authorization of relevant departments to perform tasks, the virtual electronic fence collects information obtained by popular apps installed on smartphones, as well as the MAC address and IMEI information of the mobile phone associated with the app; the physical electronic fence directly collects legal terminal four-code information from mobile phone customers. The virtual electronic fence extracts the location of user clusters, land attributes, and the mutual translation between multiple serial numbers of the terminal. Both the virtual electronic fence and the physical electronic fence exchange information with the background system.

[0044] like Figure 2 As shown, the electronic fence positioning system provided by the embodiment of the present invention is connected to the docking system through the background system (cloud server) to achieve integration with related websites. In the embodiment of the present invention, the collection radius of the physical electronic fence located at the positioning point encloses a closed area; or, the collection radius of the physical electronic fence of all positioning points, together with the area where no positioning point is required, encloses a closed area. In areas with dense Wi-Fi coverage, the physical electronic fence is preferably a Wi-Fi probe; in areas with insufficient Wi-Fi coverage, the physical electronic fence is preferably a terminal detection device.

[0045] The electronic fence positioning system provided by the present invention can realize tracking and positioning of the positioning target to assist in quickly locating the position of the positioning target. The present invention combines the technology of the physical electronic fence with the virtual electronic fence based on Internet data, enriches the data source, can clean up redundant data, and improve the credibility of information; it can use the Internet's tracking ability for smartphone applications to reasonably plan the deployment of smartphone electronic fences, reduce the monitoring range, and save control resources.

[0046] In order to protect personal privacy, the electronic fence positioning system and positioning method provided in the embodiments of the present invention adopt multiple permission control methods, including but not limited to: 1) the system login is protected by a user name, password and verification code; 2) the use of this electronic fence positioning system requires the work certificate number and ID number of the law enforcement officer; 3) authorization to use a specific computer, the same user name and password are invalid when logging in to another computer; or 4) this electronic fence positioning system is only for use by national law enforcement agencies, and a confidentiality agreement with the unit's seal is required when using it.

[0047] The following uses the scenario of finding a positioning target as an example to illustrate the specific implementation steps of the virtual-real electronic fence positioning method provided by the embodiment of the present invention, but this does not constitute a limitation of the present invention. For example, the electronic fence positioning method provided by the present invention can also be used to locate a specific means of transportation. Therefore, the "positioning target" in the present invention refers to a movable object, person, animal, etc.

[0048] <First Embodiment>

[0049] like Figure 1 As shown, the first embodiment of the present invention discloses a virtual-real electronic fence positioning method, which at least includes the following steps:

[0050] S11: Get virtual points based on the information obtained in the task

[0051] Before implementing the task of locating a target, one situation is that the mobile phone number, IMSI information, IMEI information or MAC address of the target has been obtained; another situation is that the location where the target appears has been obtained, such as the house number of the target's home address, the location of the hotel where he has stayed, the Internet cafe he has visited, the coffee shop where he has watched short videos, etc. Using this information, a virtual point can be obtained using a virtual electronic fence.

[0052] The data stored in the SIM card on the terminal for mobile communication includes the International Mobile Subscriber Identity (IMSI), the authentication key (KI), the authentication and encryption algorithm, the telephone directory, etc. The identification of the SIM card usually uses the IMSI information, which is globally unique and is used to identify the only user in the network. The International Mobile Equipment Identity (IMEI) is the serial number of the terminal itself, which is also unique. It has a one-to-one correspondence with the terminal and identifies the only terminal in the GSM and UMTS networks.

[0053] On the other hand, every terminal with Internet access has a network card and therefore has a corresponding MAC address. These MAC addresses can be collected using APP software to form a "MAC address and longitude and latitude comparison database", also known as a "Wi-Fi positioning database". Since there are true and false MAC addresses in the terminal feature data, it is necessary to identify the MAC address. One method is to judge based on the true and false MAC address filtering rules - that is, the definition of a legal MAC address is combined with the global Organization Unique Identifier (OUI) library for identification and distinction, which can be used for real-time judgment of true and false MAC addresses; the other method is to directly compare with the global Organization Unique Identifier (OUI) library to distinguish the authenticity of the MAC address.

[0054] like Figure 4 As shown, the backend system (cloud server) provides a multi-code translation function to mine relevant real identities and / or virtual identities according to the query request.

[0055] like Figure 5 As shown, multi-code translation is based on data mining technology to establish a corresponding relationship between MAC address, IMEI information, IMSI information and mobile phone number (referred to as four codes, other information such as address, time, etc. may also be included in other embodiments), and provide four-code or multi-code query services based on the corresponding relationship. As is well known, the MAC address, IMEI information, and IMSI information collected by existing physical electronic fences are only single data and cannot provide valuable data support. However, the background system in the present invention associates the four codes of the mobile phone. For example, when a user uses an APP, the APP obtains the IMEI information and mobile phone number of the mobile phone, that is, uploads them to the background system, and the background system establishes a connection between these three types of data. Another APP obtains the user's mobile phone number and MAC address and uploads them to the background system. The background system establishes a connection between the mobile phone number and the MAC address, and then the MAC address, mobile phone number and IMEI information are connected, thereby realizing multi-code translation.

[0056] The backend system can also associate the information obtained through the physical electronic fence with the above four codes. For example, if the physical electronic fence obtains one of the four codes of the mobile phone of the positioning target at a certain place, the address and time obtained by the physical fence are associated with the above four codes.

[0057] Utilizing the above-mentioned multi-code translation function, the present invention can extract the location of user clusters based on personnel positioning data, Internet behavior data, and the location coordinates of the acquisition device, and translate the multiple serial numbers of the terminal, etc., to obtain the trajectory and the location and duration of stay. Based on any known mobile phone serial number, it is possible to translate other types of serial numbers, first obtain the location information through the virtual electronic fence, and then control it through the physical electronic fence, collect the real communication signal, and confirm the location of the positioning target; based on the mobile phone serial number obtained through the physical electronic fence, it can also be transferred to the virtual electronic fence through the background system to query the previous movement trajectory of the serial number. Therefore, the positioning efficiency is improved.

[0058] Smartphones' browsing, shopping, gaming, and registration and authentication of certain applications will associate MAC addresses, IMEI information, IMSI information, and mobile phone numbers with related applications. Individual applications will provide good privacy protection, but for positioning targets, when relevant departments are performing official duties and can retrieve relevant information, they will conduct big data analysis on the historical information of multiple APP applications in recent months, and obtain the association of the four codes. They can analyze the specific location and residence time of the mobile phone at certain time points, thereby obtaining relatively accurate virtual points based on Internet information. Virtual points are usually marked with longitude and latitude. For cases with communication and email addresses, the geographical address and house number expressed in Chinese characters will also be displayed, which makes it easier for the control plan generation module to associate the specific address with the local entrance and exit and vehicle and pedestrian passages corresponding to the address, providing the best reference for the deployment of the types and quantities of physical electronic fences, and facilitating readability when humans participate.

[0059] These virtual locations come from the big data analysis engine of the background system. You only need to input one of the four codes of the mobile phone to automatically generate these virtual points. The big data analysis engine includes a database of multiple codes in one for communication equipment, and one code can be associated with multiple other codes. In this embodiment, the four-code-in-one database is used as an example for explanation. The information related to the four codes includes: a record of the device corresponding to the four codes appearing in a certain place at a certain time (which can be obtained by a physical electronic fence or a virtual electronic fence), identity information (photo, ID number, other certificate number), virtual account number, phone number of the person who frequently communicates with the mobile phone corresponding to the four codes, geographic location and identity information of the person who frequently communicates, etc. The big data analysis engine can translate multiple codes and provide relevant information associated with the above four codes to generate a deployment plan for deploying a physical electronic fence.

[0060] S12: Determine the setting range by combining the electronic map near the virtual point.

[0061] According to the virtual point obtained in the above steps, the virtual point is located in the electronic map. Then, with the virtual point as the center and the predetermined distance as the radius (for example, 500 meters), a set range is obtained on the electronic map, such as Figure 1 The range is indicated by the middle shading.

[0062] The reliable collection radius of the virtual electronic fence is 500 meters, which is larger than the collection radius of the existing physical electronic fence. For example, the collection radius of the security-reinforced Wi-Fi probe is 50 meters; the collection radius of the security-reinforced mobile phone code detection electronic fence is 150 meters. That is, the predetermined distance is larger than the collection radius of the physical electronic fence. Preferably, the predetermined distance is 2 to 3 times larger than the collection radius of the physical electronic fence. Precisely because the collection radius of the virtual electronic fence is larger than the collection radius of the physical electronic fence, expanding the scope of each collection can reduce the need for the physical electronic fence while maintaining the collection accuracy, thereby saving related human resources.

[0063] S13: Searching for a location point where a physical electronic fence needs to be set within the set range.

[0064] According to the electronic map, various terrains such as roads, lakes, buildings, and forests within the set range can be found. For each road within the set range, the entrance of the road closest to the virtual point is set as the positioning point; for buildings within the set range, the entrance of the building is set as the positioning point; no positioning point is set for lakes, forests, etc.

[0065] The distance between multiple positioning points should not be too large. It is necessary to ensure that the collection radius of all positioning points encloses a closed area (if there is no lake, forest, etc., there is no need to set up positioning points); or ensure that the collection radius of all positioning points, together with lakes or trees, encloses a closed area, and no fence blind spots are left. In cities, the effective collection radius can be set to 70% of the nominal value, and as little as 8 physical electronic fences can guard the main channels; the distance between multiple positioning points should not be too small, so as to facilitate the deployment of physical electronic fences. For the pursuit of a key target, as little as 8 physical electronic fences can guard the main channels and form a closed area. In order to reduce the number of positioning points, the collection positioning points are mainly set on channels and entrances and exits. High-rise buildings, lakes, etc. can be deployed less or not according to actual conditions.

[0066] In areas with dense Wi-Fi coverage, such as shopping malls, homes, and cafes, Wi-Fi probes are mainly used (Wi-Fi probes are used in combination with mobile phone code detection); in areas with insufficient Wi-Fi coverage, such as squares and mobile phones, mobile phone code detection is mainly used (Wi-Fi probes are used in combination with mobile phone code detection equipment and network audit equipment). For cafes, guesthouses, and hotels that are known in advance and have relatively coordinated collection points, the positioning points should try to deploy network audit equipment in advance to obtain more and more detailed Internet access information of the positioning targets.

[0067] As an alternative, the backend system receives the collected information from all positioning points in real time with the corresponding location information, matches whether the serial code contains the positioning target, analyzes the positioning target and location, and then issues a notification and generates a planning map (i.e., deployment plan) for the positioning points where the physical electronic fence is deployed. The deployment plan is sent to relevant personnel to guide them to deploy the physical electronic fence at the positioning point.

[0068] In an embodiment of the present invention, a specific deployment plan may include: combining the historical trajectory of the virtual electronic fence and map information, generating the type and quantity distribution of the physical electronic fence and the optimal approach route, selecting the optimal deployment intersection / gate, and the optimal signal collection radius and other information.

[0069] S14: Verify that a physical electronic fence has been deployed at the location.

[0070] The background system forms a topology map of the positioning points set in the previous step to guide relevant personnel to deploy physical electronic fences at the positioning points.

[0071] Physical electronic fences can be physical devices such as terminal code detection equipment, Wi-Fi probes, network audit equipment, etc. that can collect the location of specific signals. After the physical electronic fence is installed at the positioning point, it sends positioning information to the background system, which verifies that the physical electronic fence has been deployed to the correct positioning point based on the topology map or planning map.

[0072] As an alternative, if a physical electronic fence has been deployed at the positioning point in advance, in this step, a notification can be directly sent to the physical electronic fence located at the positioning point through the background system according to the topology map or planning map to activate the physical electronic fence.

[0073] At the same time, the background system needs to send specific numbers that need to be collected to the physical electronic fence, such as MAC addresses, IMEI information, etc.

[0074] S15: Acquire the collected information from the physical electronic fence and send it to the background system.

[0075] The physical electronic fence that is deployed or activated collects information from specific numbers and sends it to the background system in real time.

[0076] S16: The background system receives the collected information of all positioning points in real time, analyzes it and issues a notification.

[0077] The background system receives the four mobile phone codes, Internet access information and corresponding location information collected from all positioning points in real time, matches whether any of the four mobile phone codes contains the positioning target, and notifies relevant personnel after analysis to facilitate further control plans.

[0078] The backend system collects information from the Internet through the virtual electronic fence (online content, websites browsed, geographic location of Wi-Fi hotspots, social media accounts, shopping expenditures, shopping platforms, etc.), combined with information obtained through the physical electronic fence (part of the mobile phone four-digit code, online content, browsed websites, social media accounts, etc. obtained by the physical electronic fence), and the location information of the physical electronic fence itself (information such as the latitude and longitude coordinates of the physical electronic fence). It can associate other information not captured by the physical electronic fence, and calculate the credibility of whether the target is a positioning target, thereby informing relevant personnel whether this mobile phone is a target that needs to be tracked.

[0079] After each mission, the relevant experience will be recorded in the background system, indicating which type of physical electronic fence is the most effective at that point, which type is not so effective, and which type can be left unused next time, and fine-tuning the next deployment location. Therefore, after each business execution, it will be found that after deploying physical electronic fences at some positioning points, the actual collected information is not ideal (for example, there is signal interference near the positioning point), and this information will be fed back to the background system. The background system will adjust the position of the physical electronic fence near the positioning point accordingly when planning the topology map next time.

[0080] <Second Embodiment>

[0081] By using the technical solution of the first embodiment, after determining that the positioning target is within the area of ​​the electronic fence, in order to provide the best path to approach the positioning target to the relevant personnel, the following steps are further included:

[0082] S20: Collecting positioning information of each deployed physical electronic fence on the positioning target.

[0083] S21: combining the actual position information of each physical electronic fence and the positioning information of each physical electronic fence on the positioning target, calculating the distance from the positioning target to each physical electronic fence.

[0084] S22: Calculate and select the best path from each physical electronic fence to the positioning target in combination with the electronic map within the electronic fence area. In the embodiment of the present invention, the "best path" includes the path with the shortest time required for walking and / or vehicle movement.

[0085] S23: Issue an optimal path prompt.

[0086] According to the best path prompt, relevant personnel located near different physical electronic fences can choose the path to quickly reach the location of the positioning target.

[0087] <Third Embodiment>

[0088] Combine the following Figure 6 This article introduces how to use the electronic fence positioning method provided by the embodiment of the present invention to locate a person at a predetermined location. As described above, after the user logs in to the backend system through an account, the backend system can compare the location of the physical electronic fence with the location corresponding to the information collection task. If the locations are the same or similar, the user is given permission to use the physical electronic fence to collect data.

[0089] S30: Suspicious information collected at the scheduled deployment location

[0090] Continue to collect information at the scheduled deployment location. If there is suspicious information collected, then query based on the suspicious information, obtain the serial number of other codes corresponding to the suspicious information from the background system through multi-code mutual translation, and then proceed to the next step to start the positioning process; otherwise continue to collect.

[0091] The suspicious information can be any of the four codes of the mobile phone of the target. If the suspicious information is the MAC address, it will be sent to the background system through the virtual electronic fence. Through the big data calculation and comparative analysis of the background system, the IMSI information, mobile phone number and IMEI information of the mobile phone corresponding to the MAC address will be obtained.

[0092] S31: Physical electronic fences deployed at predetermined locations capture information

[0093] Use the physical electronic fence (terminal code detection equipment, Wi-Fi probes, network audit equipment) to obtain the serial number of each terminal within the triggering range of the physical electronic fence.

[0094] S32: Determine the required serial number.

[0095] The serial number captured in the previous step is sent to the background system for judgment. If it is a serial number related to the suspicious number (the required serial number), the required serial number is sent to the background system and then proceeds to the next step; if there is no serial number related to the suspicious number among the captured serial numbers, return to the previous step to continue capturing information.

[0096] S33: Convert the required serial number into a plurality of related numbers.

[0097] The backend system uses the multi-code translation function to convert the required serial number into other related numbers, such as mobile phone number, IMSI information, IMEI information, Internet URL, virtual account of Internet APP, etc.

[0098] S34: The backend system conducts analysis and judgment based on multiple related numbers to determine the positioning target.

[0099] The backend system determines whether the terminal is owned by the positioning target based on the IMSI information, IMEI information, virtual account of the Internet APP, etc., and obtains the recent movement trajectory and time of the positioning target based on the Internet URL and the virtual account of the Internet APP with positioning function, and confirms again whether the positioning target is near the physical fence. If yes, it is confirmed that the positioning target is near the physical electronic fence that captured the position. In this case, the backend system server sends the identity information of the positioning target, the recent movement trajectory and time of the positioning target, the approximate location, the mobile phone number and other information to the physical electronic fence, and ends the process. If not, the position of the physical electronic fence is adjusted according to the new deployment plan given by the backend system.

[0100] <Fourth Embodiment>

[0101] Next, combine Figure 7 The electronic fence positioning method provided by the fourth embodiment is further introduced. In this embodiment, positioning the positioning target based on the predetermined number includes at least the following steps:

[0102] S40: The background system obtains a collection task and obtains a suspicious number.

[0103] The backend system obtains the collection task from the relevant website or other channels. For example, the collection task is a serial number (suspicious number) of a known suspicious object's mobile phone.

[0104] S41: Based on the suspicious number, using the virtual electronic fence, deploying the location points of the physical electronic fence, and obtaining the relevant number.

[0105] By using the aforementioned virtual electronic fence, the virtual location of the suspicious number is determined based on the action trajectory and action pattern related to the suspicious number. Then, the virtual location is used to determine multiple positioning points where physical electronic fences need to be deployed using the method in the first embodiment. In addition, physical electronic fences are deployed at each positioning point.

[0106] At the same time, by utilizing the multi-code translation function of the background system, all related numbers corresponding to the suspicious number are queried and fed back to the deployed physical electronic fence, so that the physical electronic fence can collect any one of the related numbers.

[0107] S42: Collect relevant numbers or suspicious numbers in real time through the physical electronic fence and send them to the background system.

[0108] When collecting mobile phone information, the present invention does not need to pre-install APP software on the terminal, but only needs to collect it through the physical electronic fence, so the mobile phone owner can collect it without any perception. The physical electronic fence at each positioning point collects relevant numbers or suspicious numbers in real time and sends them to the background system.

[0109] S43: Determine whether the collected related number or suspicious number is the required number.

[0110] In this step, the background system can translate the serial number into other formats through the virtual electronic fence to check whether it is the information corresponding to the suspicious number, that is, to determine whether it is the required number.

[0111] S44: The backend system conducts analysis based on multiple related numbers to determine the location target

[0112] This step is the same as S34 and will not be described in detail here. After the dual collection and confirmation of the physical electronic fence and the virtual electronic fence, the collection and comparison process ends.

[0113] The electronic fence positioning system and positioning method provided by the present invention are introduced above. In an embodiment of the present invention, the virtual electronic fence combines the historical trajectory and real geographic information of the smart phone to obtain the correlation between multiple codes, and can analyze the specific location and residence time of the mobile phone at a specific time point, thereby generating the type and quantity distribution of the physical electronic fence, the optimal approach route, the optimal deployment intersection / door, and the deployment plan of the optimal signal collection radius. The physical electronic fence itself has satellite positioning capabilities, and the positioning information is presented in real time on the virtual and real electronic fence management system, and the MAC address, IMSI information, and IMEI information of the collected smart phone are uploaded in real time. These physical electronic fences are approached and compared with the historical positions of the monitored mobile phones marked on the Internet until the physical electronic fence captures the real signal of the monitored mobile phone, thereby realizing the combination of virtual electronic fences and physical electronic fences to narrow the monitoring range, obtain the specific location of the monitored signal in a targeted manner, and save the resources required for deployment (required personnel or physical electronic fences).

[0114] The Internet-collected data provided by the virtual electronic fence can guide the deployment quantity, deployment method and deployment timing of the physical electronic fence, thereby providing the optimal deployment plan; the actual data collected by the physical electronic fence becomes an important reference data for the next data analysis of the virtual electronic fence. The data provided by the virtual electronic fence and the physical electronic fence together provide a complementary basis for the monitoring and analysis of the background system, thereby improving the accuracy and real-time nature of the judgment.

[0115] Therefore, the electronic fence positioning system and positioning method provided by the embodiments of the present invention have the following technical features:

[0116] 1. Using virtual electronic fences, the location, number and radius of virtual collection points can be flexibly deployed to meet various practical needs. Targeted deployment plans can be automatically generated to achieve one deployment plan for one task;

[0117] 2. Use virtual electronic fences to reduce the deployment scope of physical electronic fences, reduce costs, and reduce the resources required for deployment;

[0118] 3. Through the direct collection and analysis of terminal signals by physical electronic fences, there is no need for the cooperation of pre-installed APP when collecting mobile phone information, and the collection is realized without the perception of the mobile phone owner, without the need for his active cooperation, thus expanding the application scenarios;

[0119] 4. Combine the data of the physical electronic fence with the data of the virtual electronic fence to achieve the mutual translation of multiple terminal codes, maximize the use of communication data, Internet data and collected information, and improve the accuracy and effectiveness of positioning.

[0120] The above is a detailed description of the virtual-real electronic fence positioning system and positioning method provided by the present invention. For those skilled in the art, any obvious changes made to it without departing from the essence of the present invention will constitute an infringement of the patent right of the present invention and will bear corresponding legal responsibilities.
