Problems solved by technology

[0003] Thieves often use windows or balconies to burglary. When installing through-beam detectors and curtain detectors on balconies or windows, due to the frequent opening and closing of windows, through-beam detectors and curtain detectors cannot distinguish indoor Alarms triggered by personnel during normal activities require frequent arming and disarming of the system using remote controls or keyboards
If you forget to disarm when the system is armed, it may trigger a large number of false alarms; if you forget to arm the system when it is disarmed, it may be illegally sneaked into or broken into by illegal personnel, which greatly reduces the practicality and popularity

Embodiment 1

[0035] Such as figure 1 The shown anti-intrusion alarm for preventing entry by climbing over a balcony or a window includes: a first sensing unit for sensing the direction of movement of people; for sensing the movement of indoor people inside the sensing area of ​​the first sensing unit The second sensing unit; the controller judging the intrusion status according to the sensing conditions of the first sensing unit and the second sensing unit; an alarm circuit that works when the controller judges as intrusion.

[0036] In the present invention, the sensing area of ​​the first sensing unit is the monitoring area, and the sensing area of ​​the second sensing unit is the buffer zone, so as to realize the judgment of the normal activities of the indoor personnel and reduce the false alarm rate of the alarm.

[0037] The first sensing unit and the second sensing unit of the present invention can use technologies such as infrared, microwave, laser, video detection, smoke sensing, ...

Embodiment 2

[0039] Such as figure 1 As shown, this embodiment is optimized on the basis of the above embodiments, that is, the alarm circuit includes a local alarm unit and / or a signal transmission device. The local alarm unit can use sound alarm, light alarm, sound and light alarm or other alarm equipment to realize local alarm. The signal transmission device realizes the remote transmission of the alarm signal, realizes the connection with the residents' handheld terminal, property supervision system, public security system and other equipment, so that the emergency systems of the residents can take timely anti-theft measures after being invaded.

Embodiment 3

[0041] Such as figure 1 As shown, this embodiment is optimized on the basis of the above embodiments, that is, when sensing people, the infrared technology is specifically used. The first sensing unit adopts a curtain type sensing unit, and its sensing area 1 is a curtain type; the second sensing unit adopts a wide-angle sensing unit, and its sensing area 2 is a monitoring area with a certain angle and forms a certain angle with the first sensing unit , to form a buffer. Such as figure 2 , 3As shown, the distribution diagram of the sensing area of ​​the first sensing unit and the second sensing unit, the first sensing unit detects the moving direction of the person, and the direction curtain detector is preferred, and its sensing area is small, which can reduce misjudgment , to avoid interference from outdoor objects. The direction curtain detector is based on the infrared principle, combined with the infrared sensing element and the corresponding curtain Fresnel lens, it...

Abstract

A trespass prevention alarm configured to prevent someone from breaking into a house through a balcony or a window and a trespass prevention method. The alarm comprises: a first sensing unit, configured to sense a movement direction of a person; a second sensing unit, configured to sense a movement of an indoor person in a predefined range in a sense area (1) of the first sensing unit; a controller, configured to determine, according to sense results of the first sensing unit and the second sensing unit, a trespass condition; and an alarm circuit, configured to operate when trespass is determined. The above alarm can differentiate trespass and a normal activity of an indoor person without setting or resetting an alarm, and has a low false alarm rate.

Description

technical field [0001] The invention relates to the field of anti-theft alarms, in particular to an anti-intrusion alarm used to prevent entry into a room by climbing over a balcony or a window. Background technique [0002] There are many anti-intrusion devices on the market today, which are based on infrared detection technology. The beam detector and curtain detector based on infrared detection technology are the most widely used front-end detection devices of the anti-intrusion system. The principle of the through-beam detector is: the light emitter emits pulsed infrared rays, which are received by the light receiver after being focused by the optical mirror. When the infrared pulse beam is blocked or the light receiver cannot receive infrared rays, the alarm host will control the alarm. The principle of the curtain detector is: the infrared ray emitted by the human body is refracted by the curtain Fresnel lens group, and when it is received by the pyroelectric sensor e...
