Description
Technical field
The present invention relates to a kind of telltale, relate in particular to a kind of alarm.
Background technology
Day by day universal along with broadband internet, video transmission on the internet becomes easily, and network makes the scope of transmission of video no longer be subject to the restriction of wiring distance, so people start to say that Video Applications is in alarm fields such as antitheft, fire prevention.But there is a problem in this application, because unpredictable, to time of fire alarming, can when occur, therefore existing network video signal is all transmission continuously, from start until shutdown or network interruption, video data can continue transmission at network, to prevent from missing potential alert event, but such method of operation can take a large amount of network bandwidth resources, user also needs constantly ceaselessly to note observing the live video transmitting, in order to avoid miss alert event, because behaving, be to be difficult to the long-term notice that keeps high concentration, and adopt this transmission mode, when occurring, real alert event can not effectively highlight, therefore there will be unavoidably the situation about misrepresenting deliberately of failing to report.
The sensor that infrared sensor, gas sensor occur as perception events, in modern warning device, also be widely used, but the status information of these sensors is often independent mutually with other equipment and channel, does not effectively combine with field video signal.
Summary of the invention
The object of the invention is to make up the deficiency that prior art exists, provide a kind of by event driven Internet video alarm.Described alarm will be in the past separately independently vision signal and all kinds of alarm sensor signal integrations to together with, overall treatment will be transferred to user after mutually confirming again.
For achieving the above object, the present invention adopts following technical scheme:
An event driven Internet video alarm, comprising: photographing module, video encoder, microprocessor, ethernet communication module, sensing module;
Described photographing module connects video encoder, and described video encoder, ethernet communication module and sensing module are all connected with microprocessor.
Sensing module by Event triggered after, produce state encoding signal and be transferred to microprocessor, by microprocessor output order, ordering about video encoder encodes the live video of photographing module shooting, and encoded video is passed back to microprocessor, microprocessor, by after encoded video and state encoding signal integration, is transferred to user terminal by ethernet communication module.
Described microprocessor connects memory module, and described encoded video and state encoding signal storage are in memory module.
Further, described sensing module is one or more in infrared sensor, UV sensor, gas sensor, electric parameter sensor, temperature sensor, sound transducer, shock sensor, wireless senser.
Described video encoder is hardware coder or software encoder.
Described ethernet communication module is wired IEEE802.3 module, wireless IEEE802.11 module and one or more in 3G wireless module.
In the present invention, except the trigger event of various sensors can drive microprocessor transmission data, by user or factory setting, fixing or the regularly instruction of transmission of video and state encoding information, and the picture that photographing module is caught changes, all can drive microprocessor to carry out data transmission and storage, make user when there is not sensor-triggered event, also can recognize field conditions.
Compared with prior art, technical scheme provided by the invention has following beneficial effect:
1. without continuous transmission video signal, significantly reduced the expensive campus network that invalid video signal and data are brought;
2. when effectively alert event occurs, user can judge field condition timely and accurately by the field video signal of transmission and each inductor status information transmitting simultaneously, without constantly observing, greatly improve efficiency, reduced the manpower of wrong report loss and loss.
3. sensing module can be set flexibly and arrange in pairs or groups according to different environments for use by multiple sensors, and the confirmation that can mutually combine of the data between each sensor further reduces wrong report probability.
