Wireless/wired intelligent logical safety theft-proof system

Abstract

The system comprises: a sensing system and a host machine. When the system is at a defenses state and the radio vibration probe of the sensing system detects an invader attempting to open the door, the host machine doesn't give an alarm but only giving three bell sounds, and meanwhile enters into a pre-alarm state; if the damage goes on, then the host machine gives the alarm and dials the phone number of the master; if in a preset time length, there is no second trigger, the host machine enters the defense state again. After combining the infrared probe with the micro vibration probe to build a logic relation, only at the condition in which both probes are simultaneously triggered, then the host machine gives an alarm. The invention is an energy-saving system; one battery can keep a 1-2 year service time.

Description

【Technical field】 [0001] The invention belongs to the technical field of safety protection and alarm, and relates to a wireless / wired intelligent logic safety anti-theft system. 【Background technique】 [0002] Existing alarm systems and devices are a lot, including existing infrared anti-theft alarm and laser anti-theft alarm though it can be found that someone enters the warning area, but it cannot be judged whether it is the owner or the thief. [0003] Existing video monitoring systems require manual monitoring. If hundreds or even thousands of points are to be monitored at the same time, it is expensive and impossible. Existing image recognition anti-theft alarm system can only monitor sixteen points. The monitoring points also need to be fixed areas, such as: bank safes, treasure houses, prisons, etc., and the cost is expensive. [0004] Existing full-automatic multifunctional anti-theft alarm (application number 91226069.6) for identifying the owner is to adopt a cer...

The monitoring points also need to be fixed areas, such as: bank safes, treasure houses, prisons, etc., and the cost is expensive

[0004] The existing fully automatic multi-functional anti-theft alarm for identifying the owner (application number 91226069.6) uses a specific frequency signal to identify the owner. The disadvantage is that it has poor anti-interference performance and poor confidentiality due to the use of wireless transmission and reception methods.

[0008] 1. In this kind of anti-theft system, the wireless transmitting sensor powered by an independent battery must be in the monitoring state at any time 24 hours a day, so it will consume the battery very fast if it is always on, so that there will be intermittent monitoring in the middle;

[0009] 2. This kind of anti-theft device cannot achieve real intelligent anti-theft. The external environment makes the vibrator vibrate, resulting in false alarms
