Abstract

The utility model discloses an automatic surveillance camera machine of recording a video can cut off power supply, including image gathering module, code control module, transmission interface module, power module, power management module, storage module, wherein storage module is used for preserving the video video recording, power management module is used for charging for the battery to during the external power source disconnection, through its inside switching, can use the battery to supply power for the camera, the utility model discloses have energy -conserving efficiency, when the use is battery powered, can fall the frame code to the video flowing voluntarily for reduce the camera consumption. The utility model discloses also can normally record and preserve the image when external power source and transmission line disconnection, energy -conserving optimization under the battery powered mode in addition can prolong the live time of camera.

Description

Can the CCTV camera of power-off automatic video recording
Technical field
The utility model belongs to field of picture communication, particularly a kind of can the CCTV camera of power-off automatic video recording.
Background technology
Along with the progress and development of society, family and public safety more and more rely on CCTV camera.And in many occasions, especially in some social hotspots events or case dispute, monitoring video is the most direct evidence all the time.In actual applications, normal two the most critical factors obtaining camera review, first is power supply, and second is store.
The existing CCTV camera overwhelming majority is by external low-voltage DC power supply, and inside there is no other stand-by power supplies, and thus once occur to have a power failure or sabotage, video camera cannot work.
In addition, video camera itself does not generally possess memory function, and image is sent by the transmission medium such as coaxial line or netting twine, and stored by other equipment.And once transmission line disconnects, even if shooting function obtains image, also cannot preserve, perform practically no function.
Therefore, if improvement can be made in above two, to normally obtaining video recording, have very important significance.
Summary of the invention
The utility model relies on externally fed completely to solve existing video camera, do not have stand-by power supply, do not possess from memory function, and do not have the shortcomings such as power saving design, and a kind of of proposition can the CCTV camera of power-off automatic video recording.
The utility model internal battery, also can normally use when external power source disconnects, built-in memory module, also can preserve image when transmission line disconnects; In addition do energy saving optimizing for battery powered pattern, extend the service time of video camera.
The utility model has carried out following improvement to existing video camera:
Memory module is added, for preserving video record in video camera inside; Back-up source is integrated into video camera inside simultaneously, and Real-Time Monitoring is carried out to outside electric power thus supplied, once external power source disconnects, enable front end immediately and store video recording.Further, when the design is also for powered battery, in order to reduce power consumption, extend working time, energy saving optimizing is done to video camera, when external power source disconnects, automatically can fall frame coding to video flowing, for reducing the power consumption of the many coding control module of power consumption in video camera, extend the service time of video camera.
Accompanying drawing explanation
Fig. 1 is system connection layout of the present utility model.
Fig. 2 is working-flow figure of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be described in detail.
Can the CCTV camera of power-off automatic video recording, comprise photoelectric conversion module, image processing module, coding control module, coffret module, power module, power management module, battery, memory module; As shown in Figure 1, the part in dotted line frame is the basic module of CCTV camera to connected mode between each module.Wherein,
Image capture module, is converted to the signal of telecommunication by light signal, generates original digitized image; And further by image processor, original digitized image is transformed the digital picture close with real image.
Digital picture carries out encoding and compressing by coding control module, stores and transmission to facilitate; For mega pixel web camera common on market today, the image control mold meeting per second sends 25 frames or more view data to coding control module, so large data volume, need the electric energy that expends also very large in compression coding process, when powered battery, electric energy is limited, therefore in order to save electric energy, falls frame coding under this pattern to video flowing; Relatively conventional mode is in two continuous frames data, gives up a frame, only encodes to a wherein frame, so just can save electric energy, extend the service time of battery, fall the video flowing after frame coding, have slight card during broadcasting to pause, but be also to meet most of demand monitored.
Image after coding is sent by transmission cable or wireless network mode by coffret module.
Power module is used for providing electric energy for other all modules.
Power management module inside comprises battery, charging circuit and testing circuit, and when externally fed is normal, the electric energy from outside is supplied to power module by power management module, for providing the electric energy of camera operation; Charged the battery by charging circuit simultaneously, detect externally fed in real time by testing circuit and whether exist; When externally fed disconnects, power management module automatically can carry out control and switch, battery is used to power for power module, and can by this information by level indicating signal informed code control module, when using externally fed, level indicating signal is high level, and when using powered battery, level indicating signal is low level.Coding control module, by detecting the level height of level indicating signal, just can judge current powering mode.
Memory module comprises storage control and memory, and wherein storage control obtains the view data after coding from coding control module, and by its write memory; Memory is nonvolatile memory, and after power down, data are not lost.
Backup battery uses lithium polymer battery, and the life-span is long, and capacity is large, good stability.
The real system of above-mentioned module composition, workflow can with reference to the description of figure 2.After video camera start, light signal is converted to digital video frequency flow and issues coding control module by image capture module in real time, coding control module detects the height of level indicating signal in real time, when level indicating signal is high level, image capture module presses default setting to digital coding video data, and gives other equipment by coffret module transfer; When external power source breaks down or disconnect, energy supply control module switches power supply source rapidly, be power module transmission of electric energy by battery, level indicating signal is become low level simultaneously, coding control module detects that level indicating signal becomes low level, will change current coding rule, changes into and falls frame coding, to save electric energy, extend the use duration of battery.
