Vehicle monitoring data acquisition system

Abstract

The invention discloses a vehicle monitoring data acquisition system, and the system comprises a front-end subsystem, a vehicle-mounted subsystem, an optical fiber transceiving unit, a front-end processing subsystem, a transmission subsystem and a data center management subsystem; the front-end subsystem is connected with the transmission subsystem through the optical fiber transceiving unit and the front-end processing subsystem; the transmission subsystem is in optical fiber connection with the data center management subsystem, and the vehicle-mounted subsystem is connected with the front-end processing subsystem; the front-end processing subsystem comprises a camera shooting module, a snapshot module, a light supplementing module and an image processing module, and the camera shooting module and the snapshot module are connected with the image processing module. The invention has the beneficial effects that the panorama condition of a road can be obtained, the special scene near a lens can be obtained, the success rate of data acquisition is improved, meanwhile, two modes of front-end direct transmission and front-end processing backup transmission are adopted, data transmission is accelerated, and the hysteresis of data transmission is reduced.

Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a vehicle monitoring data acquisition system. Background technique [0002] Data acquisition, also known as data acquisition, is to use a device to collect data from outside the system and input it into an interface inside the system. Data acquisition technology is widely used in various fields, such as cameras and microphones, which are all data acquisition tools. [0003] Based on PC data acquisition, measurement is carried out through the combination of modular hardware, application software and computer. Although data acquisition systems have different definitions according to different application requirements, the purpose of each system to collect, analyze and display information is the same. A data acquisition system integrates signals, sensors, actuators, signal conditioning, data acquisition equipment, and application software. [0004] Today, with the rapid ...

Problems solved by technology

[0005] Although the traditional data acquisition of vehicles can obtain the data information of vehicles on the road, the recognition rate is low, and the data acquisition will fail due to the lighting environment and distance problems. Although the image processing technology has been improved, but for some It is still difficult to identify blurred images due to external factors, especially on some key roads. If data collection fails, it will give illegal personnel an opportunity and add trouble to road traffic maintenance. Traditional vehicle monitoring The front-end data volume of the data acquisition system is large, which also affects the reception of back-end data, resulting in high lag in data transmission
