Example Embodiment

[0053] The first embodiment of the intelligent monitoring method

[0054] Such as figure 1 As shown, the intelligent monitoring method includes the following steps:

[0055] S101: When the identity information of the target object is received and the target object wearing the target electronic tag moves in the monitoring area, record the time when the target object is at each position point.

[0056] The target electronic tag (Radio Frequency Identification, RFID) is composed of a coupling element and a chip. Each target electronic tag has a unique electronic code. The high-capacity target electronic tag has storage space for users to write, and it is attached to the object to identify the target Object.

[0057] The target electronic tag is placed on the target object, and the target object can be a person, pet, object, etc. that need to be monitored. For example, the target electronic tag can be fixed or worn on people or pets. The movement of the target object will drive the movement of the target electronic tag, that is, the movement of the target object is the movement of the target electronic tag. When the target object moves in the monitoring area, the radio frequency identification reader can receive the radio frequency signal of the target electronic tag, and the camera can also shoot the target object in real time.

[0058] The radio frequency identification server will receive the radio frequency signal sent by the radio frequency identification reader in real time and record the time at the same time. The time when the radio frequency signal is first received is the time when the target electronic tag enters the monitoring area. When the target object moves in the monitoring area, the time of each location point will also be recorded. From the time the target object enters the monitoring area to when it leaves the monitoring area, the time at each location is recorded.

[0059] S102: Calculate the distance between the target object and the radio frequency identification reader.

[0060] The RFID reader is fixed at a fixed position in the monitoring area. Each RFID reader will have a fixed coordinate position of its own and an identity number that identifies its identity, and associate and store the identity number and the coordinate position. In the radio frequency identification server, the coordinate position corresponds to the geographic location. When the radio frequency identification server receives the signal, it will look up the pre-stored identification number and coordinate position according to the identification number of the radio frequency identification reader that sent the signal to obtain the geographic location of the radio frequency identification reader.

[0061] When calculating the distance, it is necessary to calculate the distance between the two RFID readers and the target object. The two RFID readers are the two RFID readers closest to the target object.

[0062] S103. Determine the geographic location of the radio frequency identification reader, and calculate the geographic location of the target object at each location point based on the distance and combined with the geographic location of the radio frequency identification reader.

[0063] Since the geographic location of the RFID reader is known, the distance between the target object and the two adjacent RFID readers is also calculated, and the geographic location of the target object at each location point can be obtained.

[0064] S104: Calculate the frequency of the target object moving back and forth according to the time of each location point and the geographic location of each location point, and determine whether the target object is in a hovering state based on the frequency.

[0065] When judging whether it is in a hovering state, it mainly depends on whether the frequency of the target object moving back and forth in the monitoring area reaches the preset condition. The intelligent monitoring method of the present invention calculates the frequency of the target object moving back and forth according to the time of the target object at each location point and the geographic location of each location point, and judging by the frequency, the target object can determine whether the target object is in a hovering state. The party can directly derive from the received information whether the target object is hovering in the monitoring area, which facilitates the monitoring of the target object by the monitoring party and improves the user experience.

Example Embodiment

[0066] The second embodiment of the intelligent monitoring method

[0067] Such as figure 2 As shown, the steps S201 to S204 of the smart monitoring method are the same as the steps S101 to S104 in the first embodiment. For details, please refer to the first embodiment of the smart monitoring method. Based on the first embodiment of the intelligent monitoring method, the method further includes the following steps:

[0068] S205: Control the camera to shoot the target object, and obtain the captured image.

[0069] When the camera receives the shooting instruction sent by the radio frequency identification server, it will shoot the target object. When shooting, the camera will automatically focus. When the target object moves in the monitoring area, the camera will rotate with the movement of the target object so that the target object can be captured.

[0070] The camera sends the captured images to the radio frequency identification server for storage or other operations. The images acquired by the radio frequency identification server include both graphics and images.

[0071] When the surveillance area is large, when a camera cannot clearly capture the entire surveillance area, the surveillance area needs to be divided into several perception areas. In order to facilitate monitoring, a radio frequency identification reader and a camera are distributed in each sensing area. The camera arranged in the sensing area is bound to the radio frequency identification reader in the sensing area. When the target object moves from one sensing area to another, correspondingly, the radio frequency identification reader that reads the radio frequency signal of the target electronic tag is also transformed by the change of the sensing area.

[0072] The target object is in motion and will move from one perception area to another. For ease of description, the two adjacent perception areas to which the target object will move are named the first perception area and the second perception area. When the target object moves in the first sensing area, the radio frequency identification reader in the first sensing area perceives the radio frequency signal of the target electronic tag, and sends information to notify the radio frequency identification reader. The camera in the first sensing area is controlled by the radio frequency identification reader to shoot. When the target object moves from the first sensing area to the second sensing area, the radio frequency identification reader in the second sensing area reads the radio frequency signal of the target electronic tag on the target object and sends information to notify the radio frequency identification reader. The camera in the second sensing area is controlled by the radio frequency identification reader to shoot the target object.

[0073] S206: Send the image and the information that the target object is in a hovering state to the monitoring party of the target object. Only when the wandering state occurs, will the information of the wandering state be sent to the monitoring party, if the wandering state does not occur, the information will not be sent.

[0074] The monitoring party can be a monitoring platform, a monitor of the target object, a third party who needs to monitor the target object, and so on.

[0075] For example, when the monitoring party is a monitoring platform, the whereabouts and analyzed data of all target objects wearing target electronic tags entering the monitoring area can be viewed in real time in the monitoring platform. For another example, when the monitoring party is the monitoring person of the target object, the radio frequency identification server will only send the whereabouts of one, two or more target objects wearing target electronic tags that the monitoring person needs to monitor to the monitoring person, without contacting the monitoring person. The monitor will not receive the whereabouts of the target object associated with the monitor.

Example Embodiment

[0076] The third embodiment of the intelligent monitoring method

[0077] Such as image 3 As shown, the steps S301 to S304 of the smart monitoring method are the same as the steps S101 to S104 in the first embodiment. For details, please refer to the first embodiment of the smart monitoring method. Based on the first embodiment of the intelligent monitoring method, the method further includes the following steps:

[0078] S305. Import the geographic location of the target object at each location point into the electronic scene map.

[0079] Importing the coordinates of the geographic location into the electronic scene map can more intuitively reflect the location of the target object, and it is also convenient for the monitoring party to quickly find the target object based on the electronic scene map.

[0080] S306: Send an electronic scene map loaded with the geographic location of the target object at each location point to the monitoring party of the target object.

[0081] When sending, you can send the electronic scene map, image, wandering information and other information to the monitoring platform first, and the monitoring platform will send the electronic scene map, image, wandering status, etc. to each through the interactive platform through the monitoring party’s API interface. Monitoring party.

[0082] The API (Application Programming Interface) interface can provide applications and developers with the ability to access a set of routines based on certain software or hardware without having to access the source code or understand the details of the internal working mechanism. The API interface may be an interface of various social software, for example, the API interface of WeChat, the API interface of QQ, the API interface of School News, etc. Then the WeChat platform, QQ platform, School News and other platforms send the information to each monitoring party through the corresponding API interface, for example, to the WeChat of the guardian of the child friend. Using the platform of the intermediate party to send information to each monitoring party can save the network bandwidth and hardware cost of the system, and at the same time, it also reduces the user's network equipment investment cost and traffic usage fee.

[0083] The fourth embodiment of the intelligent monitoring method

[0084] In the above three embodiments, step 102, calculating the distance between the target object and the RFID reader, can be specifically subdivided into the following steps:

[0085] S1021. Control the radio frequency identification reader to transmit a signal to the target electronic tag on the target object, and record the transmission time of transmitting the signal. The transmitted signal may be an electromagnetic wave signal.

[0086] S1022: Record the receiving time when the RFID reader receives the feedback signal. The receiving time is the time when the target electronic tag receives the signal and feeds it back to the radio frequency identification reader.

[0087] S1023. Calculate the time difference between the receiving time and the transmitting time, and calculate the distance between the target object and the radio frequency identification reader according to the time difference and the propagation speed of the signal.
