Detailed description of the invention
The utility model mainly with ARM Cortex A8 treater for hardware core video acquisition module, voice alarm module and memory module etc. are formed hardware peripherals; Software section is by the embedded OS Linux3.2 kernel transplanted and Intelligent Recognition Algorithm constitution.System is after elevator door is opened, video image is gathered by the image capture device in lift car, video data passes to system platform after video module pretreatment, system platform built-in intelligence identification counting algorithm starts, if detect and exceed early warning number, voice module sends warning, sends instruction simultaneously and suspends elevator startup, until car number meets the requirements, will audio alert be stopped and sending enabled instruction.Soft and hardware system architecture of the present utility model as shown in Figure 1.Mainly contain hardware and software two parts to form, hardware components is with ARM Cortex A8 treater for core, and video acquisition module, power supply and interface module, voice alarm module and memory module etc. form hardware peripherals; Software section is by the Intelligent Recognition Algorithm constitution of operating system layer (the embedded OS Linux3.2 kernel of transplanting) and application layer.
A. hardware system
System hardware platform is using ARM Cortex A8 treater as hardware core as shown in Figure 2, connects the external equipment of image capture module and necessity, as modules such as storage equipment, voice cue module, power supply and string interfaces.Processor A RM Cortex A8 is based on ARMv7 framework, support High Performance low power consumption technology, processing speed brings up to more than 1GHz from 600MHz, and High Performance media processing supported by 128 SIMD engines, and complete MMU makes CortexA8 can run rich operating system in various application program; Image capture module realizes the pretreatment of image acquisition, encoding and decoding and frame figure; Power supply and interface module provide electric energy for whole system and realize corresponding string and and the interface function such as USB; The operation of memory module principal security efficient stable and storage environment.The integrated system block diagram that hardware components is is control core with ARM Cortex A8 treater, ARM Cortex A8 treater mainly realize to whole system run management and control.When elevator door is opened, apparatus for controlling elevator sends a triggering command to ARM Cortex A8 treater by interface module, and whole checking system starts.Arm processor issues image acquisition and coding module control signal, and the video capture device in car gathers image and carries out the pretreatment work such as decoding, then passes by interface module the view data handled well back arm processor; Arm processor calls intelligent image identification counting algorithm and determines number concrete in car, if number exceedes the regulation number that takes a lift, arm processor will carry out audio alert to voice cue module control signal, give the enabled instruction of an apparatus for controlling elevator time-out elevator simultaneously, the number until car number conforms with the regulations, arm processor sends respectively to voice cue module and apparatus for controlling elevator and stops audio alert and elevator actuation signal.Memory module principal security arm processor runs and actv. storage environment the efficient stable of video data process; Power module provides electric energy for whole detecting device.B. software system
Software section operating system layer is transplanted and is met application and realize the control of software and hardware, scheduling and coordination through the Linux3.2 kernel of cutting, and application software layer is then programming image acquisition and Intelligent treatment algorithm.Fig. 3 is operating system layer linux kernel software development flow, mainly completes under cross compile system, realizes cutting and the transplanting of linux kernel.Fig. 4 is image acquisition and treatment scheme, represents the idiographic flow of the Acquire and process of frame of video figure, realizes the process of car number Intelligent Recognition.
The above-mentioned elevator based on the embedded lift car person number detection device of ARM is installed, has there is overload protection device simultaneously and comprise weight sensor and person number detection device, be double insurance elevator.
Principle of work: system is after elevator door is opened, video image is gathered by the image capture device in lift car, video data passes to system platform after video module pretreatment, system platform calls built-in intelligence identification counting algorithm, if detect and exceed early warning number, voice module sends warning, sends instruction simultaneously and suspends elevator startup, until car number meets the requirements, will audio alert be stopped and sending enabled instruction.This is practical is the embedded lift car person number detection device of arm processor based on Cortex A8, and this device has that volume is little, low in energy consumption, antijamming capability is strong and the feature such as processing speed is fast.This invention has good promotion prospect.
