CN103345807A - Security and protection monitoring system and method based on acceleration sensor - Google Patents

The invention discloses a security and protection monitoring system and method based on an acceleration sensor. The method includes the steps that acceleration is generated when a monitored target (3) is moved or when a door (4) of the monitored target (3) is opened, the acceleration sensor (1) senses the acceleration, converts the acceleration into an analog signal and outputs the analog signal to a main controller (2), and the main controller (2) triggers a control signal of a monitoring device after receiving the analog signal and controls the monitoring device to operate. False triggering will not be made any more when a person just passes and does not conduct any operation on the target, and the judgment standard is more scientific and reliable. The acceleration sensor senses the monitored target to judge whether the monitored target is moved or not or whether the door of the target is opened or not, and therefore, whether dangers exist or not is judged, the judgment standard is scientific and feasible, the sensing flexibility is strong, and accuracy is high. When dangers are sensed in the target, a sound-light alarm can be triggered, and interference and deterrent are timely given to the stealing behavior.

A kind of safety defense monitoring system and method based on acceleration transducer

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 realizes by infrared monitoring probe that usually infrared monitoring probe reach is extensive, can monitor that target to be monitored on every side very on a large scale, but infrared monitoring probe can't be monitored at specific object, can't monitor the undesired use of certain objects.

The course of work based on the safety defense monitoring system of infrared monitoring probe is: whether infrared monitoring probe has personnel to pass through around detecting target to be monitored, as long as infrared monitoring probe has personnel to pass through around sensing target to be monitored, even he does not carry out any operation (target to be monitored not being caused any threat) to target to be monitored, also can be judged to be potential safety hazard by system, and then the false triggering camera is taken pictures.

In order to address the above problem, some safety defense monitoring systems based on acceleration transducer have also appearred at present on the market, but the acceleration transducer of traditional safety defense monitoring system all is fixedly mounted on the body of target to be monitored (as proof box) usually, induction targets is better by the effect that integral body moves, but whether the door of perception target well is opened.In addition, traditional safety defense monitoring system only supports camera to take pictures, record a video, and can effectively record the figure and features feature of stealer, but can not in time be disturbed in stealer is committed theft process and frighten, and can't directly reduce user's property loss.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of novel safety defense monitoring system and method based on acceleration transducer are provided, integral body that not only can the perception target moves, also at 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; Perceiving target when dangerous, can trigger camera and take pictures, record a video, can trigger sound and light alarm simultaneously, in time the behavior of committing theft is disturbed and frightened, effectively reduce user's property loss.

The objective 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 transducers, one or more watch-dog and master controller, whether acceleration transducer is installed on the target to be monitored, is moved for detection of target to be monitored, watch-dog is arranged at the target to be monitored periphery, is used for target to be monitored is realized monitoring that master controller is used for realizing data operation and control; Acceleration transducer links to each other with the collection signal input part 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 and the master controller; Further, also be connected by wireless network communication between master controller and the monitoring probe.

As a further improvement on the present invention, described watch-dog comprises any one or the multiple combination in camera, alarming horn and the warning lamp.

A kind of security-protecting and monitoring method based on acceleration transducer, it may further comprise the steps:

S1: degree of will speed up sensor is installed on the target to be monitored, and sets up the communication between acceleration transducer and master controller, master controller and the watch-dog;

S2: when target to be monitored is moved or the door of target to be monitored when being opened, produce acceleration;

S3: acceleration transducer is sensed this acceleration, is converted to simulating signal and exports master controller to;

S4: master controller is judged to be " target to be monitored is moved or the door of target to be monitored is opened " after receiving this signal;

S5: master controller triggers the control signal of watch-dog, the work of control watch-dog.

As a further improvement on the present invention, degree of will speed up sensor is installed on the door of target to be monitored, and whether the door that is used for the induction target to be monitored is opened.

Further, described step S5 comprises following substep:

(1) master controller triggers the control signal of camera, and the control camera is taken pictures or recorded a video target to be monitored periphery situation;

(2) master controller triggers the control signal of alarming horn, and the control alarming horn sounds the alarm;

(3) master controller triggers the control signal of warning lamp, the flicker of control warning lamp.

The invention has the beneficial effects as follows:

1) replace the traditional infrared probe by acceleration transducer, for just through and the personnel that target do not carried out any operation no longer make false triggering, criterion is science, reliable more, can play the effect that reduces system loss simultaneously;

2) whether be moved by acceleration transducer perception target to be monitored or whether the door of target is opened, thereby judge whether target exists stolen danger, criterion science, feasible, and induction sensitivity is strong, accuracy height, good reliability;

3) perceiving target when dangerous, can trigger camera and take pictures, record a video, in time record the figure and features feature of stealer; Simultaneously can trigger sound and light alarm, in time the behavior of committing theft be disturbed and frightened, can effectively reduce user's property loss.

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 2, a kind of security-protecting and monitoring method based on acceleration transducer, it may further comprise the steps:

S2: when proof box is moved or the door 4 of proof box when being opened, produce acceleration;

S4: master controller 2 is judged to be " proof box is moved or the door 4 of proof box is opened " after receiving this signal;
