(1-1) be arranged on circuit board;
(1-2) be arranged in the mounting hole on protective cover.
(2) abnormal signal detects and processes: when infrared sensor detects foreign matter, block over setting-up time or magnetic sensors and detect the interval during over setting-up time of departing from normal magnetic field value, can determine abnormal, and to monitoring terminal, transmit abnormal signal by receive/hair device of signal, monitoring terminal, by the feedback of abnormal signal, is taked corresponding abnormality processing;
Wherein, described setting-up time can be self-defined according to different machinery requirements, only needs to guarantee can not judge normal running by accident, and in the present embodiment, selecting 60s is setting-up time;
The mode of described abnormality processing has following 4 kinds:
(2-1) stop user's operation;
(2-2) shutting down refusal user uses;
(2-3) provide alerting signal to terminal management person;
(2-4) directly connecting public security system reports to the police.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, utilize infrared sensor to prevent that lawless person from installing pseudo-keyboard additional and recording and steal user's bank card information on keyboard, utilize the variation of magnetic sensors by induced field to judge whether code keypad has simultaneously and install the pseudo-device that infrared sensor cannot be detected additional, as the membrane keyboard that is difficult for discovering etc., the variation of Real-Time Monitoring code keypad top and surrounding environment, abnormal alarm, effectively crime prevention behavior.
