Embodiment
Embodiment is introduced below in conjunction with Fig. 1-Fig. 2
The central processing module of the wagon flow supervisory system that the utility model detects based on live video stream and data processing module adopt STM32F103RB chip, wireless communication module adopts zigbee alarm module to adopt BL-PBZ12085CYB hummer, LCD MODULE adopts TFT color screen, video extraction adopts DS-2CE16F5P-IT5 camera, and data memory module adopts YS-41Micro SD card.
The analog image that video extraction obtains is transferred to data processing module through video signal cable and processes, after vision signal is carried out A/D conversion by data processing module, be real-time transmitted to internal memory to process, the analog picture signal generated is through over-sampling and quantification treatment, becoming digital signal is input in CPU module, carry out computing with the ultrasonic signal that ultrasonic sensor modules obtains, obtain real-time traffic flow data, be shown in face of user by TFT color screen.
Data processing module mainly realizes detecting the vehicle flowrate in video, analyze and adding up, and qualified image data information is outputted to data memory module; Transmit data acquisition pci bus mode, image transmitting speed is 533MB/S, can realize the reliable real-time transmission of video extraction to processor memory.
