[embodiment]
As shown in Figure 1, television set supervisory control system embodiment 1 comprises that television module, simulation camera module and audio frequency and video can record module.Television module comprises CPU, video decode circuit, image processing circuit, image displaying circuit and audio frequency processing circuit.It is the same with television module that camera module and audio frequency and video can be recorded module, all is installed in the casing of television set, forms independently television set supervisory control system.
The simulation camera module comprises video deriving means and audio frequency deriving means, output audio and video analog signal.
Audio frequency and video can be recorded module and be comprised audio A/D change-over circuit (AK5357 chip), video decode circuit (TW9906 chip), audio frequency and video MPEG4 coding/decoding modular circuit (Vweb2010 chip), high-capacity FLASH memory (Samsung K9K8G08U0M 1G Flash storage chip), also comprise 1 USB interface.
The Voice ﹠ Video output of camera module connects audio frequency and video MPEG4 coding/decoding modular circuit by audio A/D change-over circuit, video decode circuit respectively.The Voice ﹠ Video output of audio frequency and video MPEG4 coding/decoding modular circuit connects the audio frequency processing circuit and the image processing circuit of television module respectively.The I/O mouth of audio frequency and video MPEG4 coding/decoding modular circuit connects the FLASH memory, and the control input end of audio frequency and video MPEG4 coding/decoding modular circuit meets the CPU of television module.
The video output terminals of camera module also through the video decode circuit map interlinking of television module as treatment circuit.
Audio frequency and video can be recorded the audio, video data that module sends here front end and carry out decoded digitalization, then digitized audio, video data is sent digital MPEG-4 encoding compression processing (adopting the Vweb2010 chip to realize), the data of handling both can be kept in the inner big capacity Flash memory, also can be stored in external USB equipment by USB interface.
Television module carries out motion detection to the vision signal that camera module is sent here, and whether judge has motion conditions (as people, flame, smog etc.) to occur in the current camera image.When television module detects indoorly when having undesired motion conditions to occur, just transmit control signal immediately, make audio frequency and video can record module and start and can record task, store current audio frequency and video image.
Television module also can be used for can recording the audio, video data that module sends here to audio frequency and video and carries out playback, is convenient to the residence police's post-processed of advocating peace.Its Data Source comprises inner big capacity Flash memory and the external USB equipment that is connected by USB interface.CPU is responsible for the control to video decode, image processing, image demonstration and Audio Processing chip in the television module.
Considering all has the monitoring behavior at daytime and night, and it is bigger that illuminance can differ, and for obtaining better image information, can select the CCD camera of high luminous sensitivity for use.
Camera module also can directly adopt the digital signal output type, and the system configuration schematic diagram as shown in Figure 2 at this moment.
In the embodiment shown in fig. 3, audio frequency and video can be recorded and also be comprised a MCU (TOSHIBATMPR4938 chip) in the module, the control input end of audio frequency and video MPEG4 coding/decoding modular circuit meets MCU, is responsible for the order of video decode in this module and audio frequency and video MPEG-4 coding/decoding chip is controlled by MCU.CPU in the television module connects with this MCU, and MCU keeps communicating by letter with the CPU1 of television module, guarantees order control in order.
Big capacity Flash memory can select to preserve the capacity of 2-8 hour video recording content, is convenient to the user when not having external USB equipment or there is no need to use under the external USB equipment situation and use.The memory that audio frequency and video can be recorded in the module also can adopt harddisk memory.
As shown in Figure 4, the monitoring TV implementation method embodiment handling process of described built-in camera is as follows:
At first, the user adjusts the angle of camera, the monitor key of remote controller or select to enter monitor state by menu, and at this moment, system begins countdown in 10 seconds, is convenient to personnel and withdraws.During this was waited for, if the user has any remote controller or TV set panel button operation, system withdrawed from monitor state, returned the preceding state of button operation.Otherwise system will formally enter monitor state after countdown finishes, and will close screen display and sound playing.
After system entered monitor state, the picture that begins that camera is captured carried out motion detection and judges.
If the picture motion surpasses certain lower threshold, system is judged to be effective exercise.At this moment, if system in video recording, then keeps video recording constant, otherwise, start video process at once.
If the picture motion is lower than certain lower threshold, system just is judged to be lost motion, to avoid misoperation.At this moment, if system, judges further then whether video recording time-delay (promptly the shortest video recording duration) has arrived in video recording, if then stop video recording, otherwise continue to keep video state.Increase the video recording time-delay and mainly be for fear of the frequent starting of video recording action and stop,, avoid occurring a large amount of fragment files to keep monitoring video picture continuity.The user can set this video recording time-delay, and it is 1 minute that present embodiment is set the video recording time-delay.
Whether the key scan program of system monitor user ' at any time pushes ESC Escape, promptly at every turn motion detection judge finish after, judge all whether the user sends the instruction of withdrawing from monitor state.If, then not proceeding motion detection judges; If yes, just the demonstration dialog box waits for that then the user imports password confirming on television screen, and the beginning countdown.In the time that countdown limits, it is correct to input password as the user, just withdraws from monitor state; Otherwise, continue to keep monitor state, guarantee that monitor state is not illegally interrupted.
