Traffic flow information acquisition terminal based on Zynq-7000

Abstract

The invention discloses a traffic flow information acquisition terminal based on Zynq-7000, and belongs to the technical field of a traffic control system signal device. The traffic flow information acquisition terminal based on Zynq-7000 uses a Zynq-7000 chip as a carrier to build an architecture including a video image acquisition sensor, an external memory module and an HDMI display, uses an AXI4 bus to internally interconnect a PS (Processing System) module and a PL (Programmable Logic) module, designs an IP core for accelerating convolutional neural network calculation, implements real-time data interaction between the PS module and the PL module by using an MCU to drive a communication architecture of an AXI4-VDMA IP core and an AXI4-DMA IP core, and integrates the functions of videoimage acquisition, storage, target detection, traffic flow statistics, output display and the like into a single chip, so that digital image processing and data transmission with a high-integration level, high-speed and low-latency can meet the real-time requirements for traffic flow statistics.

Description

technical field [0001] The invention discloses a Zynq-7000-based traffic flow information collection terminal, which belongs to the technical field of traffic control system signal devices. Background technique [0002] With the rapid development of social economy, the number of urban motor vehicles has increased rapidly, the road traffic flow has increased significantly, the overload operation situation has become increasingly prominent, traffic congestion, environmental degradation, frequent accidents and other phenomena have become increasingly serious, and traffic flow monitoring has become a popular Concerned about urban management issues. For this reason, in urban road traffic management, it is urgent to use more effective technology for real-time target detection, traffic flow statistics, and management scheduling for complex road conditions, so as to realize the control of Intelligent Transportation System (ITS, Intelligent Transportation System) and improve urban t...
