A kind of safety defense monitoring system based on acceleration transducer and method
Technical field
The present invention relates to a kind of safety defense monitoring system based on acceleration transducer and method.
Background technology
At present, safety monitoring is realized by infrared monitoring probe usually, and infrared monitoring probe reach is extensive, can to monitor around target to be monitored very on a large scale, but infrared monitoring probe cannot be monitored for specific object, cannot monitor the abnormal use of certain objects.
The course of work based on the safety defense monitoring system of infrared monitoring probe is: whether infrared monitoring probe detects around target to be monitored has personnel to pass through, as long as infrared monitoring probe senses have personnel to pass through around target to be monitored, even if he does not carry out any operation (not causing any threat to target to be monitored) to target to be monitored, also can be judged to be potential safety hazard by system, and then false triggering camera is taken pictures.
In order to solve the problem, some safety defense monitoring systems based on acceleration transducer are also there are at present on the market, but the acceleration transducer of traditional safety defense monitoring system is all fixedly mounted on the body of target to be monitored (as proof box) usually, whether induction targets is better by the effect that moves integrally, but can not the door of perception target well be opened.In addition, traditional safety defense monitoring system is only supported that camera is taken pictures, is recorded a video, and effectively can record the figure and features feature of stealer, but can not be disturbed in time in stealer commits theft process and frighten, and directly cannot reduce the property loss of user.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of novel safety defense monitoring system based on acceleration transducer and method are provided, not only can the moving integrally of perception target, also on the door of target to be monitored, acceleration transducer is installed, when the door of target is opened by stealer, also can timely and effective perception; When perceiving target and being dangerous, camera can be triggered and carry out taking pictures, recording a video, can sound and light alarm be triggered simultaneously, in time the behavior of committing theft disturbed and frighten, effectively reduce the property loss of user.
The object of the invention is to be achieved through the following technical solutions: a kind of safety defense monitoring system based on acceleration transducer, it comprises one or more acceleration transducer, one or more watch-dog and master controller, whether acceleration transducer is installed on target to be monitored, for detecting target to be monitored and is moved, watch-dog is arranged at target to be monitored periphery, for realizing monitoring to target to be monitored, master controller is used for realizing data operation and control; Acceleration transducer is connected with the collection signal input end of master controller, and the control signal output terminal of master controller is connected with watch-dog.
As a further improvement on the present invention, acceleration transducer can be installed on the door of target to be monitored.
Further, be connected by wireless network communication between acceleration transducer with master controller; Further, be also connected by wireless network communication between master controller with monitoring probe.
As a further improvement on the present invention, described watch-dog comprises any one or multiple combination in camera, alarming horn and warning lamp.
Based on a security-protecting and monitoring method for acceleration transducer, it comprises the following steps:
S1: degree of will speed up sensor is installed on target to be monitored, and set up acceleration transducer and master controller, communication between master controller and watch-dog;
S2: when target to be monitored is moved or the door of target to be monitored is opened, produces acceleration;
S3: acceleration transducer senses this acceleration, is converted to analog signal output to master controller;
S4: master controller is judged to be after receiving this signal " target to be monitored is moved or the door of target to be monitored is opened ";
S5: master controller triggers the control signal of watch-dog, controls watch-dog work.
Whether as a further improvement on the present invention, degree of will speed up sensor is installed on the door of target to be monitored, be opened for the door responding to target to be monitored.
Further, described step S5 comprises following sub-step:
(1) master controller triggers the control signal of camera, controls camera and takes pictures to target to be monitored periphery situation or record a video;
(2) control signal of master controller trigger alarm loudspeaker, controls alarming horn and sounds the alarm;
(3) control signal of master controller trigger alert lamp, controls warning lamp flicker.
The invention has the beneficial effects as follows:
1) replace traditional infrared by acceleration transducer to pop one's head in, for just through and target is not carried out to the personnel of any operation, no longer make false triggering, criterion science, reliable more, the effect reducing system loss can be played simultaneously;
2) whether to be moved by acceleration transducer perception target to be monitored or whether the door of target is opened, thus to judge whether target exists stolen danger, criterion science, feasible, and induction sensitivity is strong, accuracy is high, good reliability;
3) when perceiving target and being dangerous, camera can be triggered and carry out taking pictures, recording a video, in time the figure and features feature of record stealer; Can sound and light alarm be triggered simultaneously, in time the behavior of committing theft disturbed and frighten, effectively can reduce the property loss of user.

Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, a kind of safety defense monitoring system based on acceleration transducer, it comprises one or more acceleration transducer 1, one or more watch-dog and master controller 2, acceleration transducer 1 is installed on target to be monitored 3(proof box) above, whether be moved for detecting proof box, watch-dog is arranged at proof box periphery, for realizing monitoring to proof box, master controller 2 is for realizing data operation and control; Acceleration transducer 1 is connected with the collection signal input end of master controller 2, and the control signal output terminal of master controller 2 is connected with watch-dog.
As a further improvement on the present invention, acceleration transducer 1 can be installed on the door 4 of proof box, is specially the inner side of cabinet door 4.
Further, be connected by wireless network communication between acceleration transducer 1 with master controller 2; Further, master controller 2 is also connected by wireless network communication with between watch-dog.Wireless network can adopt 315M, 433M or BT network etc.
As a further improvement on the present invention, described watch-dog comprises any one or multiple combination in camera 5, alarming horn 6 and warning lamp 7.
As shown in Figure 2, a kind of security-protecting and monitoring method based on acceleration transducer, it comprises the following steps:
S1: degree of will speed up sensor 1 is installed on proof box, and set up acceleration transducer 1 and master controller 2, communication between master controller 2 and watch-dog;
S2: when proof box is moved or the door 4 of proof box is opened, produces acceleration;
