Time, play and there is, with described, the audio alert file that doubtful incident of violence signal is corresponding；
Wherein, described AT89C51 system areal calculation based on each target corresponding to each frame lift car image is every
The real-time area change rate meansigma methods of one target, specifically, for each target, during according to the shooting of lift car image
Between tandem calculate the area change rate of this target of two frame lift car images of adjacent shooting time, and to being calculated
Multiple area change rates average to obtain the real-time area change rate meansigma methods of this target；
Wherein, described self adaptation recursive filtering unit, described gray processing processing unit, described background gray threshold determine unit,
Described background separation unit, described object-recognition unit and described data extracting unit are realized by different fpga chips respectively,
And be integrated on one piece of surface-mounted integrated circuit；
Wherein, the elevator power supply source in described machine room control equipment includes solar powered device, uninterrupted power source device, city

When controller detects civil power regular supply, described switching switch is switched to described civil power and accesses device to be provided confession by civil power
Electricity, when described switch controller detects that commercial power supply interrupts, is switched to described uninterrupted power source device by described switching switch
Part is to be provided power supply by described uninterrupted power source device, and described switch controller also provides power supply at described uninterrupted power source device
Period, decide whether that controlling described switching switch is switched to described solar energy according to the dump energy of described uninterrupted power source device
Power supply device is to be powered by described solar powered device；
Described image coding unit carries out image compression encoding based on MPEG-4 compression standard to described multiframe lift car image；
Described default gray threshold value is between 0-10, and described default detection time interval value is between the 1-5 second, described pre-
