Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 and figure 2 As shown, this peripheral intrusion detection and alarm device includes a magnetic field radiation source composed of a high-frequency current source connected to the cable I;

[0014] And a magnetic field detector composed of a connecting cable II of the detection trigger alarm device, the detection trigger alarm device is connected with an alarm.

[0015] The AA' loop formed in the cable I constitutes a magnetic field radiation source, which is connected to a high-frequency current source. Because the magnitude and direction of the current change periodically, the electromagnetic field generated by the current changes periodically, so that in the AA of the cable I 'A periodic alternating magnetic field is generated around the loop. The BB' loop formed in the cable II is in the periodically changing alternating magnetic field g...

Abstract

The invention discloses a perimeter intrusion detection and alarm device. The device comprises a magnetic field radiation source composed by the connection between a high frequency current source and a cable I, and a magnetic field detector composed by connection between a detection trigger alarm device and a cable II. The detection trigger alarm device is connected with an alarm. The perimeter intrusion detection and alarm device is simple in structure, convenient to install, low in cost, high in stability, sensitive in detection, low in false alarm rate, hidden, and capable of realizing all-day work.

Description

technical field [0001] The invention relates to a detection device, in particular to a perimeter intrusion detection and alarm device. Background technique [0002] In some important security areas, in order to prevent illegal intrusion and various sabotage activities, the traditional preventive measures are to set some (such as iron fences, walls, wire fence nets, etc.) barriers or barriers at the outer perimeter of these areas, arrange Personnel stepped up patrols. In the current situation where criminals use advanced science and technology, and criminal methods become more complex and intelligent, traditional prevention methods are difficult to meet the needs of key departments and key unit security work. Manpower prevention is often affected by factors such as time, region, personnel quality and energy, and loopholes and mistakes are inevitable. [0003] With the development of society and the progress of science and technology, the perimeter intrusion detection and al...
