Receiving a wireless signal having a strength in sequence (S44) or if the wireless signal arrival time is delayed more than the threshold (S46) it is recognized as an intrusion state and generates an alarm signal (S48) to the outside (S40).

이때 (e) 상기 (d) 단계에서 무선신호의 세기가 설정시간이상 임계치 이하로 유지되거나 무선신호도달시간이 임계치 이상으로 지연되면, 상기 태그(10) 및 억세스포인트(20) 간의 무선신호의 송수신 주기를 더 짧게 하여 정확도를 향상시키는 단계(S50)가 더 포함된다.At this time, (e) when the intensity of the radio signal is maintained below the threshold value for more than the predetermined time or the delay time of the radio signal arrival time is greater than the threshold value in (d), the transmission and reception of the radio signal between the tag 10 and the access point 20 Further shortening the period to improve the accuracy (S50) is further included.

상기 (a) 내지 (e) 단계의 수행주체 및 효과는 전술한 통신을 이용한 농작물 방범 시스템(100)에서 상술한 바 있으므로 그 설명을 생략한다.
The subjects and effects of the steps (a) to (e) are described above in the crop crime prevention system 100 using the aforementioned communication, and thus description thereof will be omitted.

한편 본 발명의 일 실시예에 따른 통신을 이용한 농작물 방범방법은 (f) 억세스포인트(20)가 침입정보를 관리서버(40)로 전송하고(S62), 상기 관리서버(40)는 유무선통신망을 통해 접속된 사용자단말기(50)로 침입정보를 전송(S64)하는 단계(S60)가 더 포함된다.On the other hand, the crop security method using the communication according to an embodiment of the present invention (f) the access point 20 transmits the intrusion information to the management server 40 (S62), the management server 40 is wired and wireless communication network A step S60 of transmitting intrusion information to the user terminal 50 connected through S64 is further included.

따라서 억세스포인트(20)로부터 침입정보를 전송받은 관리서버(40)는 유무선통신망을 통해 접속된 사용자단말기(50)로 침입정보를 전송함으로써, 지리정보시스템(GIS)과 연동하여 지도에 침입위치를 표시하여 관리자에게 제공할 수 있게 된다.
Accordingly, the management server 40 receiving the intrusion information from the access point 20 transmits the intrusion information to the user terminal 50 connected through the wired / wireless communication network, thereby integrating the intrusion position on the map in cooperation with the Geographic Information System (GIS). It can be displayed and provided to the administrator.
