In sum, under normal circumstances, anchor ear 3 is connected in protection pipe 2, the infrared ray quilt being sent by transmitter module 12 Protection pipe 2 is separated, and makes receiver module 13 cannot receive infrared ray, thus exporting low level infrared detection signal to three poles The base stage of pipe Q.

Meanwhile, together with the wing plate 4 on anchor ear 3 is securely fixed with body of wall by bolt 5, make between wing plate 4 and metope Pressure value is higher than reference pressure value, makes the voltage higher than its inverting input for the homophase input terminal voltage of comparator A, thus exporting High level signal, to the input of not gate N2, exports low level pressure detecting signal to audion Q's finally by not gate N2 Base stage.

Because pressure sensing cell 6 and infrared detection unit 11 all export low level signal, make to be coupled to above-mentioned both The audion Q of outfan is in cut-off state all the time, and buzzer SP does not report to the police.

If bolt 5 is unloaded by stealer, the pressure value between wing plate 4 and metope is reduced to below reference pressure value, makes The homophase input terminal voltage of comparator A is less than the voltage of its inverting input, thus it is defeated to not gate N2 to export low level signal Enter end, export the base stage of the pressure detecting signal of high level to audion Q finally by not gate N2.

If protection pipe 2 is detached in anchor ear 3 by stealer together with cable body 1, receiver module 13 can receive to be sent out Penetrate the infrared ray that module 12 is sent, thus exporting the base stage of the infrared detection signal of high level to audion Q.

When the base stage of audion Q receives high level signal, audion Q turns on, and buzzer SP sounds the alarm, to carry Awake staff comes to the spot, and stops pilferage behavior in time.
