Safety cabinet movement detection device
Technical field
The utility model relates to safety cabinet, particularly a kind of safety cabinet movement detection device.
Background technology
Safety cabinet is a kind of special container, is mainly used to antitheft.And along with the development of various high-new security and guard technology, the breaking techniques that Electronic safe is corresponding also constantly develops, and user is inclined to the safety cabinet of safer, the better protection property of selection.Existing safety cabinet is only limitted to local sound and light alarm, does not well monitor for surrounding environment, when the stolen situation of generation safety cabinet, cannot record stolen process, affect recovering and solving a case of safety cabinet.
The warning function of present safety cabinet is only limitted to report to the police at local acousto-optic-electric, and little to the warning message of user, user can not understand the situation at safety cabinet scene well, and the effect of warning is little, and the potential safety hazard of safety cabinet is still very large.
Utility model content
The purpose of this utility model is to provide a kind of safety cabinet movement detection device, can at least one of solve the problem.
For achieving the above object, according to an aspect of the present utility model, provide a kind of safety cabinet movement detection device, comprise pir sensor, camera, memory, night lamp, light resistor and control device, pir sensor, camera, memory, night lamp is all connected with control device with light resistor, memory is for storing video or the photo of camera acquisition, light resistor is used for testing environment brightness and is controlled the opening and closing of night lamp by control device, pir sensor is for detecting infrared rays and controlling camera collection video or photo by control device.Thus, pir sensor can obtain infrared rays that moving heating object sends and be sent to control device, and then control device controls camera collection radio frequency or photo.The setting of night lamp is convenient to camera and obtains video or photo in dark situation.
In some embodiments, safety cabinet movement detection device also comprises supply unit, and camera is connected with supply unit respectively with control device.Thus, camera is powered separately by supply unit, is convenient to make camera be in opening, can make camera collection video or photo, avoid because of start delay camera collection information when control device receives alarm signal.
In some embodiments, camera comprises the imageing sensor and video encoder that are connected, and video encoder is connected with control device.Thus, the data signal that image tactility apparatus obtains is compressed and is passed to control device by video encoder, is convenient to store.
In some embodiments, camera is pinhole cameras, thus camera can concealedly be arranged, and prevents from being destroyed.
In some embodiments, safety cabinet movement detection device also comprises communicator, and communicator is connected with control device.Thus, control device can control the client that the video of acquisition or photo are sent to user by communicator, is convenient to the security situation that user grasps safety cabinet in time.
The beneficial effects of the utility model are: pir sensor can obtain infrared rays that moving heating object sends and be sent to control device, and then control device controls camera collection radio frequency or photo.The setting of night lamp is convenient to camera and obtains video or photo in dark situation.Control device can control the client that the video of acquisition or photo are sent to user by communicator, is convenient to the security situation that user grasps safety cabinet in time.Therefore, this safety cabinet movement detection device has activity thermal objects, in real time monitoring safe case surrounding environment around detecting safety cabinet, improves the advantage of the security performance of safety cabinet.
Accompanying drawing explanation
Fig. 1 is the structural representation of the safety cabinet movement detection device of the utility model one embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 show schematically show the safety cabinet movement detection device according to a kind of embodiment of the present utility model.As shown in the figure, this device comprises pir sensor 1, camera 2, memory 3, night lamp 4, light resistor 5 and control device 6, pir sensor 1, camera 2, memory 3, night lamp 4 are all connected with control device 6 with light resistor 5, memory 3 is for storing video or the photo of camera 2 acquisition, light resistor 5 is for testing environment brightness and controlled the opening and closing of night lamp 4 by control device 6, and pir sensor 1 gathers video or photo for detecting infrared rays and controlling camera 2 by control device 6.
Pir sensor 1 is passive infrared line detector, can detect moving heating object, the toy of such as movement and people.Pir sensor 1 can obtain the moving heating object around safety cabinet in time, and is that camera 2 starts to gather video or photo, improves the security performance of safety cabinet.
The safety cabinet movement detection device of present embodiment also comprises supply unit 7 and communicator 8, and camera 2 is connected with supply unit 7 respectively with control device 6.The power source of supply unit 7 is battery.Communicator 8 is connected with control device 6.Communicator 8, for being connected with external network, can be LAN or mobile network.Communicator 8 can be network interface.Control device 6 is made up of control chip and control circuit.
Camera 2 comprises the imageing sensor 21 and video encoder 22 that are connected, and video encoder 22 is connected with control device 6.Camera 2 is pinhole cameras.
This safety cabinet course of work of mobile device is:
Supply unit 7 provides power supply for camera 1 and control device 6, opens when camera 1 and alert detecting device 5 switch on power.The alert signals such as alert detecting device 5 monitors ultrasonic wave, infrared report from a liner in real time, unblank, when after acquisition alarm signal, send it to control device 6.After control device 6 receives alarm signal, namely control camera 1 and gather video or photo.The video of collection or photo are sent to storage 2 and preserve by control device 6, by communicator 8, the video of collection or photo are sent to client simultaneously.
Light surface resistance 4 can respond to the change of safety cabinet surrounding brightness, and when brightness is less than or greater than setting value, control device 6 controls luminous lamp and opens or cut out.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
