Problems solved by technology

Since the CCD image sensor is greatly affected by the external weather and lighting environment, the detection signal of the CCD image sensor will be mixed with various noises or interference components, thereby reducing the detection sensitivity of the CCD measurement system, reducing the working dynamic range, and reducing the image signal. quality, leading to deviations in the collection of traffic flow data, which largely limits the application functions of the big data information management system

Abstract

The invention discloses a big data information management system. The system comprises a traffic flow monitoring module, a wireless transmission module and a background management server. The trafficflow monitoring module comprises a CCD image acquisition unit, an analog / digital conversion unit and an FPGA chip. The CCD image acquisition unit comprises a CCD image sensor for acquiring a traffic flow video image; a detection signal of the CCD image sensor is sent to the following filter circuit, the signal amplification conditioning circuit and the dark current suppression circuit for processing; the analog / digital conversion unit is used for converting an output signal of the signal amplification conditioning circuit into a digital quantity and then sending the digital quantity into the FPGA chip for processing; according to the urban road traffic intelligent management and control system based on the FPGA, various noise or interference components in image detection signals are well restrained, the image signal quality is improved, and intelligent management and control over urban road traffic are achieved through the big data processing technology.

Description

technical field [0001] The invention relates to the technical field of traffic information management, in particular to a big data information management system. Background technique [0002] Aiming at the serious uneven and unpredictable temporal and spatial distribution of vehicle traffic in the urban road traffic system, which can easily cause traffic congestion, based on the massive video data collected in the urban traffic monitoring system, combined with video image recognition technology and big data mining technology, the establishment of urban The road traffic big data information management system is used to command and mobilize the daily travel mode of vehicles. Existing methods for monitoring traffic flow mainly collect video images of traffic flow by setting a CCD image sensor at the front end of the monitoring host, and the collected video images are processed by an image acquisition unit and then transmitted to a data processor. Since the CCD image sensor is ...
