Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It should be noted that the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
It should be noted that, with the development of network technology, in the field of public security, various security systems are used to ensure people's daily life and prevent illegal criminal activities. However, at present, each security system is an independent security system fixed at a specific position, and each independent security system can only monitor a fixed area and cannot share monitoring data. The technical scheme provided by the embodiment of the application can realize the sharing of the monitoring data of each independent security system and improve the target tracking efficiency.
Specifically, as shown in fig. 1, the structure diagram of the security system provided in the first embodiment of the present application is shown. As can be seen from fig. 1, the security system 1 provided in the embodiment of the present application includes a server 10 and at least one terminal 11, and it can be understood that the number of the terminals 11 may be 1 or any integer greater than 1. The server 10 is in communication connection with each terminal 11, the server 10 is configured to send a tracking instruction for a target object to each terminal 11, and generate a motion trajectory of the target object according to position information of the target terminal, where the tracking instruction carries identity characteristic information of the target object, and the target terminal is the terminal 11 that sends tracking success information to the server 10 from all terminals 11. Each terminal 11 is configured to respond to the tracking instruction, determine whether the target object is tracked according to the identity information acquired in real time and the identity characteristic information of the target object, and send a tracking success message to the server 10 when the target object is tracked.
It is understood that, in practical applications, the server 10 and each terminal 11 need to be connected to the internet, so that a communication connection can be established between the server 10 and each terminal 11. After the communication connection is established between the server 10 and each terminal 11, the server 10 controls each terminal 11 to perform tracking of the target object by transmitting a tracking instruction for the target object to each terminal 11.
By way of example and not limitation, the server 10 is a server of a public safety organization, such as a server of a public safety system, and the terminal 11 is a control terminal of a security subsystem of the public safety organization, such as a control terminal of an entrance guard subsystem, a control terminal of a parking lot management subsystem, a control terminal of a hotel management subsystem, a control terminal of a video monitoring management subsystem, and the like. It can be understood that, in order to further improve the control efficiency of the server 10 on the terminals 11, and implement that the identity characteristic information carrying the corresponding category is selectively sent according to the information categories of the identification information of different terminals 11, in an alternative implementation manner, before the server 10 sends the tracking instruction for the target object to each terminal 11, each terminal 11 registers on the server 10 and uploads the information type of the corresponding identification information to the server 10, and the server 10 may send the tracking instruction for the target object to each terminal 11 according to the registered information of each terminal 11 and the information type of the corresponding identification information of each terminal. It can be understood that, when each terminal 11 registers on the server 10, it needs to upload corresponding registration information, where the registration information may be at least one of basic data information such as an address, a name, and a security type corresponding to each terminal 11.
For example, each security subsystem of the public security organization sends a registration application to a server of the public security organization, and after the application is received, each security subsystem realizes logical connection with the public security organization, and the identity recognition devices of each security subsystem, such as a fingerprint reading device, a human face capturing device, an iris reading device, a number plate photographing recognition device, a voiceprint reading device, a second-generation identity card reading device, and the like, become each terminal 11 of the public security system 1. Thus, the server sends the identity feature information of the target object, such as the suspect a, to each terminal 11, which is equivalent to that the search comparison of a is performed on all terminals registered on the server 10 in a city or even a country, and the effect of searching the suspect a by each terminal is obviously wider, more accurate and more efficient than the search range of criminal investigation/technical investigation personnel in a database at the bottom of a case.
As an example and not by way of limitation, when the subsystems register, the information types of the identification information corresponding to the subsystems can be uploaded to the server through the control terminals, after the server receives the information types of the identification information of the security subsystem uploaded by the control terminals, the received information types can be stored, and when a tracking instruction for a target user needs to be sent, the tracking instruction carrying the corresponding desired information types is sent to the terminals by referring to the information types. Understandably, the terminal 11
In this embodiment, the server may store the information type in a pre-established detection information pool, where the information detection pool is used to store the identity characteristic information of the target object (person or object) searched by the public safety organization. For example, if the searched target object is a case suspect, the identity characteristic information includes at least one of information such as a fingerprint, a face photo, a conversation record, an identity card number, a photo and the like of the case suspect; if the searched target object is a traffic accident vehicle, the identity characteristic information comprises a vehicle photo, license plate information and the like of the accident vehicle, the server classifies the identity characteristic information of the target object, and sends different types of identity characteristic information to corresponding terminals according to the information types of the received identification information of each terminal, for example, if the terminal is a monitoring device of a certain cell, the information type of the corresponding identification information can be image information comprising a human face or fingerprint information, and the server can send a target object tracking instruction carrying the human face image information and/or the fingerprint image information to the terminal; if the terminal is a management device of the parking lot, the information type of the corresponding identification information is a license plate number, and the server can send image information carrying the license plate number to the terminal. It should be noted that the server 10 may perform operations such as updating, adding, deleting, and the like on the detection data in the detection information pool at regular time, so that the detection information pool can provide more accurate detection data.
It can be understood that, since the installation location of each terminal 11 is fixed and there is a time record in the tracking process, each terminal 11 uploads the respective location information and timestamp information to the server 10 while sending the tracking success information, and the server 10 can determine the motion trajectory of the target object according to the location information of the target terminal tracked to the target object and the tracked timestamp information, thereby providing a good clue and means for tracking the target object.
It should be noted that, in an alternative implementation manner, the tracking success information may include the timestamp information, and when each terminal 11 registers on the server 10 and uploads the information type of the corresponding identification information to the server 10, it may also upload the corresponding location information to the server 10.
It can be understood that, when the server 10 receives the tracking success information and determines the motion trajectory of the target object according to the position information and the timestamp information of the target terminal, and then the tracking task of the target object is completed, the server 10 may send a tracking stop instruction for the target object to each terminal 11, and each terminal 11 deletes the response process of the tracking instruction after receiving the tracking stop instruction.
According to the target object tracking method, a server of a security system sends a tracking instruction for a target object to at least one terminal of the security system, each terminal responds to the tracking instruction and judges whether the target object is tracked according to identity information acquired in real time and identity characteristic information of the target object, and after the target terminal tracks the target object, tracking success information is sent to the server, and after the server receives the tracking success information sent by the target terminal, the server generates a motion track of the target object according to position information of the target terminal. The server controls each terminal in at least one terminal to track the target object in real time, and further generates the motion track of the target object according to the position information of each target terminal tracking the target object, so that the purpose that a plurality of terminals in a security system track the target object in real time is achieved, and the tracking efficiency of the target object is improved.
Fig. 2 is a schematic diagram of an interaction process of implementing target object tracking by the security system shown in fig. 1 according to the second embodiment of the present application. As can be seen from fig. 2, the interaction steps between the server 10 and each terminal 11 when the security system of the present application tracks a target object are as follows:
s201, the server 10 sends a tracking instruction for the target object to at least one terminal 11, where the tracking instruction carries identity characteristic information of the target object.
It should be noted that, since the communication process between the server 10 and each terminal 11 is the same, in the embodiment shown in fig. 2, only one terminal 11 is shown for convenience of display, and in practical applications, the number of terminals 11 may be 1 or any integer greater than 1. Specifically, after receiving a target object tracking instruction triggered by a user, the server 10 needs to acquire identity feature information of the target object, where the identity feature information may be uploaded by the user or acquired from a pre-established detection information pool. It is understood that, in order to improve the working efficiency of each terminal 11, the server 10 may select to send the identity feature information including the information type of the corresponding identification information to different terminals 11 according to the information type of the corresponding identification information uploaded by each terminal 11 in advance.
Further, the server 10 may transmit a tracking command for the target object to each of the terminals 11 according to the information type of the identification information corresponding to each of the terminals 11. It can be understood that the target object tracking instruction carries identity feature information of a type matching the information type of the identification information of the corresponding terminal.
In an optional implementation manner, in order to ensure communication security between the server 10 and each terminal 11, before the server 10 sends a tracking instruction for the target object to each terminal 11 according to an information type of the identification information corresponding to each terminal 11, detection data in a first preset format is generated according to the identity characteristic information of the target object and a preset first field, and the detection data is sent to a downlink stack of a preset information exchange stack of each terminal 11. The downlink stack is used for storing the detection data sent by the server 10.
As shown in fig. 3, which is a schematic structural diagram of the detection data in the first predetermined format, as can be seen from fig. 3, the detection data in the first predetermined format includes: category, sequence number, command, data and check code; the category represents a data type, the sequence number is generated by the server 10 according to the sequence of the target object tracking task in the task to be executed, the command is the execution task sent by the server 10 to each terminal 11, and is generally composed of binary digits with preset meanings, for example, "00" represents the start of search, and "11" represents the end of search, and the like, the data is the identity characteristic information of the target object, and the check code is generated by the server according to the identity characteristic information, so that the function of preventing errors in the transmission process or data field information from being forged can be achieved.
S202, each terminal 11 responds to the tracking instruction, and judges whether the target object is tracked or not according to the identity information acquired in real time and the identity characteristic information of the target object.
It should be noted that each terminal 11 is pre-established with a user identity template, the user identity template is established by the terminal 11 according to the user identity characteristic information collected historically, when the terminal 11 responds to the tracking instruction, the identity template of the target object may be generated according to the identity characteristic information of the target object, and the identity templates of all users detected within a preset time period are dynamically compared to search the target object.
It can be understood that, for the security of data communication, in an optional implementation manner, each of the terminals 11 obtains the detection data from the downlink stack of the information exchange stack, executes a corresponding instruction according to the detection data, if the detection data includes a start search instruction, executes a tracking instruction for the target object, and determines whether to track the target object according to the identity information acquired in real time and the identity feature information of the target object included in the detection data. And if the detection data comprises a search stopping instruction, deleting all responses for executing the tracking task by the terminal, and finishing searching.
S203, if the terminal 11 tracks the target object, sending a tracking success message to the server 10.
And S204, the server 10 generates a motion track of the target object according to the position information of the target terminal, wherein the target terminal is a terminal which sends tracking success information to the server 10 from the at least one terminal 11.
In an optional implementation manner, in order to ensure communication security, if the terminal 11 tracks the target object, detecting identification information in a second preset format is generated according to respective corresponding location information and a preset second field, and the detecting identification information is stored in an uplink stack of the information exchange stack, where a mapping relationship exists between the detecting identification information and the detecting data. It should be noted that, when the terminal 11 stores the detection identification information in the uplink stack of the information exchange stack. Correspondingly, after receiving the tracking success information, the server 10 obtains the detection identification information from the uplink stack of the information exchange stack, and determines the motion trajectory of the target object according to the detection identification information.
Further, the server 10 transmits a stop tracking instruction for the target object to each terminal 11, and each terminal 11 deletes a response progress of the tracking instruction after receiving the stop tracking instruction. Further, after receiving the instruction to stop tracking, each terminal 11 ends the dynamic search process for the target object by deleting the identity template of the target object.
Fig. 4 is a schematic diagram of the detection identification information in the second predetermined format. As shown in fig. 4, the detecting identification information in the second predetermined format includes: category, serial number, callback, time, template number. The type and the sequence number are correspondingly consistent with those in the detection data, the reply instruction is a reply instruction generated according to a command in the detection data, the reply instruction is also composed of a binary number with a preset meaning, for example, "01" indicates that a search template is established, the search is started, "10" indicates that the matched data is found, that is, the tracking is successful, the reply is made to the instruction sent by the server 10, the time filling is the time stamp information for searching the target object, and the template number is mapped with the check code in the detection data. Thus, after receiving the detection identifier word sent by the terminal 11, the server 10 can obtain the time and the place of the target object according to the detection identifier word, and further can generate the motion trajectory of the target object according to the time and the place.
As can be seen from the above analysis, in this embodiment, a server of a security system sends a tracking instruction for a target object to at least one terminal of the security system, each terminal responds to the tracking instruction, determines whether the target object is tracked according to identity information acquired in real time and identity characteristic information of the target object, and sends tracking success information to the server after the target terminal tracks the target object, and the server generates a motion trajectory of the target object according to position information of the target terminal after receiving the tracking success information sent by the target terminal. The server controls each terminal in at least one terminal to track the target object in real time, and further generates the motion track of the target object according to the position information of each target terminal tracking the target object, so that the purpose that a plurality of terminals in a security system track the target object in real time is achieved, and the tracking efficiency of the target object is improved.
Fig. 5 is a schematic diagram of an interaction process between the server and the terminal shown in fig. 1 according to a third embodiment of the present application. As shown in fig. 5, in this embodiment, compared with the embodiment shown in fig. 2, the implementation processes of S502 to S505 are the same as the implementation processes of S201 to S204, except that the following interaction process is further included before S502:
s501, each terminal 11 registers on the server 10, and uploads the information type of the corresponding identification information to the server 10.
Specifically, the process of registering each terminal 11 on the server 10 is described in detail in the embodiment of fig. 1, and is not described herein again.
Fig. 6 is a schematic diagram illustrating an interaction process between the server and the terminal shown in fig. 1 according to a fourth embodiment of the present application. As shown in fig. 6, compared with the embodiment shown in fig. 5, the present embodiment has the same implementation process from S601 to S605, except that after S604, the following interaction process is further included:
s605, if the terminal 11 receives the instruction for stopping tracking of the target object sent by the server 10, the terminal 11 deletes the response process of the tracking instruction.
That is, after the server 10 generates the motion trajectory of the target object, it determines that the tracking task for the target object is completed, at this time, the server 10 sends a stop tracking instruction to each terminal 11, and when the terminal 11 receives the stop tracking instruction for the target object sent by the server, the terminal deletes the response process of the tracking instruction.
For example, suppose a person a who lives in S city is reported by family for a plurality of days to lose contact, the contact ways such as telephone, social networking and the like are interrupted, and the family can only provide a photo of a. The public security department in the S city submits the photo and the ID card number of the person A to a public security system in the S city, and a server of the public security system pushes the photo and the ID card information of the person A to be searched to a downlink stack of an information exchange stack of a corresponding terminal in a data word detecting mode according to the information type of the identification information corresponding to each registered security subsystem. And respectively searching the A corresponding to the terminals for identity authentication by using the face recognition technology and the identity card, and sending tracking success information to the server after the identity information of the A is searched, wherein the server can generate the motion track of the target object according to the position information of the terminals for identity authentication by using the face recognition technology and the identity card and the timestamp information in the tracking success information. Specifically, each terminal which performs identity authentication by using a face recognition technology and an identity card correspondingly can create an identity template of a according to a photo and the identity card of the terminal a, dynamically compare the identity template of the terminal a with the identity template corresponding to the user detected in a preset time period, create an uplink stack in which a detection marker word is written in an information exchange stack, and inform a server that the terminal has started to search if the content of a response field of the detection marker word is '01'. And in the subsequent identification process of the user, the A is identified. After the information of the A is identified, the terminal creates a new detection identifier word, the command return field is set to be 10, the person A is found, and the detection identifier word is written into an uplink stack of the information exchange stack; the server establishes the motion track of the searched person A according to the detection identifier words retrieved from different terminals. For example, the server learns that an attendance/entrance guard rule of an enterprise has appeared by face recognition of a person A according to the detection identification word information of a plurality of terminals, and the person A is paid by face brushing through an online shopping platform and is checked to enter a station by using an identity card at a railway station, and the public security department can find the person A who is lost in contact through the movement track of the person A. Further, after the search work of the lost contact person is finished, the server pushes the detection data carrying the "search end" command to the downlink stack of the information exchange stack of the relevant terminal, and the content of the command field is "11", which indicates that the search work of the person is finished. And after receiving the search ending instruction, each related terminal deletes the process for executing the search A, and the scheme is ended.
As can be seen from the above analysis, in the embodiment of the present application, on the basis of the embodiment shown in fig. 2, the server 10 further sends an instruction to stop tracking the target object to each terminal 11 after the tracking is successful, and each terminal 11 deletes the response process of the tracking instruction after receiving the instruction to stop tracking the target object, so that each terminal 11 can be protected from being affected while ensuring information security.
