Embodiment

By describing technology contents of the present utility model in detail, realized object and effect, accompanying drawing is coordinated to be explained below in conjunction with embodiment.

The design of the utility model most critical is: by using WIFI unit to replace original UHF signal transmitting unit, improve the anti-interference of intrusion detector.

Please refer to Fig. 1, a kind of intrusion detector, comprise power supply unit 20, processing unit 30 and intrusion sensor 40, also comprise WIFI unit 10, described processing unit 30 is electrically connected with intrusion sensor 40 and WIFI unit 10 respectively, and described power supply unit 20 is electrically connected with processing unit 30 and WIFI unit 10 respectively;

Described power supply unit 20 provides power supply for giving processing unit 30, intrusion sensor 40 and WIFI unit 10;

Described intrusion sensor 40 for detecting in intrusion detector monitoring range whether produce invasion signal, and sends trigger pip by processing unit 30 to WIFI unit 10 when the invasion signal detected;

Described WIFI unit 10 for when receiving described trigger pip to main frame wireless signal emission.

Wherein, Fig. 3 is the power principle figure of WIFI unit 10, and described main frame is the Receiving Host of antitheft security system, and main frame receives the signal that intrusion detector sends, and outwardly sends circular information or warning; Described processing unit 30 is single-chip microcomputer or other microprocessors.

Because WIFI has multiple channel, when detecting that neighbouring WIFI equipment has used certain channel, WIFI unit 10 can skip this channel, selects idle channels to send wireless signal to main frame, makes transmission unlikely loss or disturbed.

Seen from the above description, the utility model intrusion detector use WIFI unit 10 replaces the UHF sending module in original intrusion detector, WIFI is provided with multiple channel, and select idle channels to send wireless signal to main frame, thus reduce between intrusion detector or between intrusion detector and other neighbouring WIFI equipment mutual interference, improve anti-interference and the stability of intrusion detector.
