Description

The multi-purpose intelligent burglar alarm

Technical field

The utility model relates to a kind of burglar alarm, is a kind of multi-purpose intelligent burglar alarm, is applicable to the burglar alarm on ground such as family, office, warehouse, can be used as to give the correct time and time switch etc. under non-alarm condition.

Technical background

The burglar alarm of Chu Xianing in the market, can roughly be generalized into two big classes from realizing that function is distinguished: a class is the warning of non-paging formula, promptly when taking place, larceny utilize sensor signal to trigger acoustics, sound with burst frightens the thief away, but stolen scene or near during unmanned, will lose the warning effect, and the lawless person can also destroy warning device according to sound source, so audible alarm there is the shortcoming of poor reliability; Another kind of is the warning of paging formula, after the schedule time that monitored door, window are illegally opened, replace telephone set to dial automatically by alarm, utilize telephone wire to send preassigned number again by owner, as dial ordinary telephone set, call out beeper or mobile phone etc., stolen incident has taken place so that owner in time takes measures in the owner of notice called phone machine, beeper or mobile phone.The paging formula alarm of this kind structure, can be with alarm access in parallel telephone wire with room telephone, being installed in very hidden place and alarm procedure is difficult for being found by the burglar, thereby the warning reliability is improved, but when the lawless person at telephone set off-hook or drag telephone wire in advance before the dialing automatically, owing to send out number failure, also can lose the warning effect, in addition, this kind paging formula alarm can not be installed in the place with Device for anti-fraudulent use telephone line, therefore still has the shortcoming that reliability is relatively poor, function is few.Other has a kind of radio paging type alarm, and though improved major step on reliability, there are shortcomings such as cost is higher, degree of intelligence is relatively poor, function singleness, unfavorable popularization in above-mentioned relatively paging formula alarm, and the utmost point has improved necessity.

Summary of the invention

The purpose of this utility model is a kind of multi-purpose intelligent burglar alarm of design, can overcome the shortcoming of existing paging formula burglar alarm, when monitored door and window is illegally opened, needn't utilize telephone set just can trigger the calling alarm action snugly, send the telephone number signal that owner presets by telephone wire, stolen incident has taken place in the owner-monitoring place of notice designated telephone machine or pager or mobile phone, can improve the reliability and the degree of intelligence of warning significantly, simultaneously, this alarm also has the function except that burglar alarm, under non-alarm condition, can realize giving the correct time, timing function can a tractor serves several purposes.
