Embodiment

The utility model is described further below in conjunction with the drawings and specific embodiments.

As shown in figure 1, whole system includes：Intelligent display terminal based on Android platform, embedded digital video camera with Video analysis main frame, PLC power carriers local side, PLC power carriers terminal and PLC interchangers.

PLC electrical carriers local side is by power line and PLC power carrier terminal communications, and PLC power carrier terminals are with being based on Intelligent display terminal, embedded digital video camera, the video analysis main frame of Android platform are connected on PLC interchangers by netting twine Communicated.

In order to ensure the security of the lives and property to greatest extent, whole system is powered using back-up source, and back-up source is respectively PLC power carriers local side, PLC power carriers terminal and PLC interchangers and video analysis main frame are powered, when having a power failure During abnormal failure, whole system still two hours of normal work are can guarantee that, time enough is provided to emergency management and rescue.

In the system, PLC power carrier local sides are arranged at computer room, and a back-up source is provided for it, by PLC electricity Power carrier terminal, PLC interchangers and video analysis main frame are arranged at elevator car top, and provide back-up source for it, by base Intelligent display terminal, embedded digital video camera in Android platform are arranged on inside lift car, again by elevator The back-up source of car roof is powered for it, so as to realize on the basis of original elevator structure is not changed, by each of the system Part is installed.

In said system, the need for actual functional capability, intelligent display terminal, embedded digital video camera or video analysis Main frame is selectable unit (SU).

Intelligent display terminal based on Android platform：It is mainly used to remove monitoring electricity in the state of realization does not change elevator structure The terraced speed of service, the direction of motion, vibration frequency, angle of inclination, rush to summit, the elevator major hidden danger such as crouching bottom；Other intelligent display is whole End is furnished with full duplex video intercom system, deserves full duplex video intercom system and is communicated by PLC, runs into catastrophic failure When, user can one-key start video intercommunication, set up and contact with emergency center or property, remotely also can actively start intercommunication and car Interior personnel link up in time.

Embedded digital video camera and video analysis main frame：Cab interior video is locally deposited in real time by digital camera Storage, by plc communication Cloud Server can be uploaded to when running into abnormality alarming by front and rear 10 frame video data, in addition to influence electricity Terraced normal using causing the behavior of hidden danger to be identified by video analysis main frame, such as object keeps off door, and pin, which is kicked, waits action, simultaneously It is combined using the on off state of video analysis elevator door with the various kinds of sensors of intelligently screen, realizes the non-flat bed switch gate of elevator Judge, and alarm is sent according to default abnormal behaviour.

As shown in Fig. 2 intelligent display terminal, which includes FLASH chip, is used for storage system and supervision elevator data information, DDR Exchanged as internal memory, user processing system caching accelerates the speed of service, LCD-LVDS provides driving for HD video display, Camera1 is video input, and external digital camera, AudioIN is microphone input, is mainly used to receive environmental volume and people Acoustic information, AudioOUT is audio output, and this three and Key are combined as video intercom system, by using six axle gyros Instrument（Acceleration and gravity sensor）Collection number and then gestured computing by CPU, calculate elevator traffic direction information, speed letter Breath, inclination information etc., CPU is as the heart of system, and the intelligent display terminal can be developed based on Android system.

, so can very big basis as shown in figure 3, video analysis is using video capture circuit and analysis circuit independent design User needs flexible selection, using the Video coding based on H264 and image recognition algorithm come the on off state to elevator door, Be acquired and analyze with the demeanor of passenger-in-elevator, when there is abnormality alarming, listened outside such as door area ladder, break, object gear door Behavior of the elevator normally using safety is influenceed, these data and image can be passed through the tunnels of RTSP mono- forwarding intelligence by video capture circuit Display terminal, another road is communicated by PLC and sent and Cloud Server, finally each provides corresponding information by high in the clouds and intelligence screen Prompting is alerted.

Failure diagnostic process decision logic is as follows：

Rush to summit failure：When intelligent screen receive floor data that proximity switch transmits close to attic by gyro Instrument is monitored elevator traffic direction and is determined as failure of rushing to summit when still being continued up with the speed certain more than threshold value

Crouching bottom failure：When intelligent screen receive floor data that proximity switch transmits close to ground floor by gyro Instrument is monitored elevator traffic direction and is determined as crouching bottom failure when still being continued up with the speed certain more than threshold value

Hypervelocity alarm：Velocity sensor detects elevator speed more than threshold value alarm

Vibrations alarm：Gyroscope detects vibrations and exceedes preset value

Door stops ladder outside area：It is without speed or specific less than some that proximity switch detects non-flat bed AND velocity sensors Threshold value

Running open：Video analysis Host Detection is in non-normal working floor to enabling AND proximity switches

Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art Art personnel, without departing from the concept of the premise utility, can also make some improvements and modifications, these improvements and modifications Also it should be regarded as in the utility model protection domain.
