Description

The family endowment terminal of the video calling for help of collection health service remote nursing and help function

One, technical field

The present invention relates to communication technical field, be particularly related to audio/video encoding/decoding and network transmission technology, the present invention, as family endowment intelligent terminal, can be old man the functions such as family endowment required " health service (receiving health information broadcast and program request, health consultation, Telediagnosis of Electrocardiogram Signals) ", " video is called for help and sought help ", " remote nursing ", " grandparent and grandchild is to looking " is provided.

Two, background technology

Network digital video technique, was widely used in the industries such as traffic, finance, public security, education, national defence, customs, electric power, telecommunications, broadcasting and TV in recent years, became the important means of enterprises and institutions' safety precaution.

Say simply, network digital video technique, after exactly the captured analog video signal of camera being compressed by video server, transmit by the Internet, user can browse on-the-spot real-time video and Video Document by login central platform in any one sensible place of network again.Online video chat, instant (for example QQ) video calling all belongs to typical network digital video technique.The network digital video in past, main transmission medium is cable network.Along with emergence and the fast development of 3G (Third Generation) Moblie technology (3G), network video technique is just towards wireless future development.3G wireless video technology is the perfect adaptation of modern communication technology and video processing technique, is embodying state-of-the-art technology and the trend of digital video technology.

Digital video frequency server (DVS) is a kind of typical network digital video equipment, is the most basic equipment of network video technique, and it bears video compression coding and Internet Transmission task.Current, H.264 the video compression algorithm great majority of network video product all adopt video compression standard of new generation that IEO/IEC and ITU-T Liang great International Standards Organization jointly formulate.On coding, H.264 adopt the compact design of " returning basic ", option that need not be numerous, obtains the compression performance more much better than MEPG-4, can meet the demand of different rates, different resolution and different transmission (storage) occasions.Technically, code flow structure network adaptability is H.264 strong, has increased error resilience, can adapt to well the application of IP and wireless network.In transmission, H.264 can transmit the video flowing based on networking protocol (IP) with lower data rate, at aspects such as video quality, compression efficiency and data packet recovery loss, surmounted existing MPEG-2, MPEG-4 and video communication standard H.26x, be more suitable for narrow band transmission.

In sum, network digital video technique, is the very active research field of current Video processing and the 3G communications field.Various application emerge in an endless stream.But, network digital video technique is applied to old man's family endowment service, also rare.And the present invention takes the course of its own, take network digital video technique as basis, aspect a lot of, do things creatively, be bold in innovation, for the elderly provides a kind of family endowment intelligent terminal, thereby develop a kind of brand-new end product that possesses high intention.

Three, summary of the invention

The object of the invention is for demands such as the required health service of the current the elderly's family endowment of concentrated solution, acute disease are called for help, life is sought help, children's remote nursings, and a kind of intelligent terminal of developing.

Core technology of the present invention, realizes by following technical proposals.

(1) hardware technology scheme: adopt on-chip system chip as central data processing module, by the built-in 3G wireless module of mini-PCI interface, by the built-in wireless receiving module of input/output interface.In addition, also built-in audio-video collection module, camara module, video output and display module, ethernet interface module, large capacity SD card memory module etc.

(2) mode that adopts IP broadcast and IP video intercom to combine, realizes remote health service function.The mode that starts Internet Transmission by button operation realizes the health information video frequency program that receives broadcast or program request health service center, can select a plurality of health service center by button, the health service center of selecting and pointing out current service by the mode that word shows and sound report combines.

(3) adopt a key remote control mode to start Network Video Transmission, when wireless receiving module receives after remote controller signal, equipment is immediately initiatively to first-aid centre or Community Service Center's pushing video, by A Jian Xiang first-aid centre, carry out video calling for help, by B Jian Xiang Community Service Center or children's mobile phone, carry out video and seek help.When video is called for help, video pictures is with address contact information and medical history information; When video is sought help, by the mode exposition need of text addition.

(4) adopt the mode of IP video intercom, by remote controller key alternative, realize the function that user carries out health consultation to health service center doctor on duty, both sides can see the other side's video, can hear the other side's sound, can support to select to seek advice to a plurality of doctors on duty by button.Adopt in the same way, select visual object, can realization and the function of children or other old partner's video intercom.

(5) adopt built-in ethernet module and 3G wireless module, compatible for wired and 3G are wireless two kinds of mode accessing Internets, by sequence number and handset binding, the mode of encrypted code is encrypted mandate again, support is carried out long-distance video by 3G smart mobile phone and is checked, thereby realize the children that live that are not together, old man is carried out to the function of remote nursing.

(6) in order to protect privacy of user, can open and close camera by remote controller key mode, under camera closed condition, when video is called for help, automatically open camera.

(7) adopt 12 buttons to complete all functions operation except video calling for help and seeking help, 12 buttons are respectively: " to code switch ", " emptying code ", " camera selection ", " camera switch ", " last object ", " next object ", " health information ", " information program request ", " cardiac diagnosis ", " to looking switch ", " write switch ", " playing back videos ".

(8) adopt 5 indicator lights to indicate various states, be respectively: be strong and weak with flicker number oftimes indication 3G signal; Adopt the bright or indication camera on off state that goes out of lamp; Adopt green light indication electrocardio normal, when red indication anomalous ecg, whether uncertain bright indication is simultaneously normally, by a bright indication of lamp and memory video, called for help and sent.

(9) adopt mini-USB interface, support to be connected with handheld electrocardiograph, the last electrocardiogram (ECG) data of measuring is pressed serial port protocol packing, by 3G mobile network, is transferred to remote diagnostic center, and diagnostic center diagnostic result directly shows by indicator light in terminal.

(10), by external video input interface and video output interface, support external video camera and external tv machine to show, the built-in or external device by button choice for use.

(11) adopt large capacity SD card memory module, by button mode, start and close video and the local camera video that far-end transmits and record a video, and carry out playing back videos by button operation mode, showing screen display.

(12) after device start not during button operation in holding state, under holding state, loop play scenery picture and music.
