In this way, each induction terminal stores this chip identity information. Subsequently, each induction terminal will generate a connection request based on this chip identity information and periodically send out connection requests. In this way, after receiving the connection request, the mobile terminal will determine whether to connect to the corresponding induction terminal according to the analysis result of the connection request.

In this way, the target object itself and the area near the current location in the natural scenic area garden can be calibrated, which is convenient for subsequent association of the image feature information and the positioning information, and then association of the real-time monitoring information of the target object corresponding to different layout positions, so as to generate the activity path information of the target object in the natural scenic area garden.

Subsequently, each sensing terminal will generate a connection request based on the chip identity information and send the connection request outward periodically. In this way, after the mobile terminal receives the connection request, it will determine whether to connect with the corresponding sensing terminal according to the analysis result of the connection request.

[0084] Preferably, instructing each sensing terminal to generate a connection request based on the NFC hardware identity information and send the connection request outward at a corresponding period, and also changing the period of the next outward connection request according to the connection situation of each outward connection request, includes:

[0085] Step A1, before sending the connection request, use the following formula (1) to add a connection count identifier about the NFC hardware identity information to the connection request, and the response message of the connection request retains the connection count identifier about the NFC hardware identity information and returns the response in the last four digits,
