Expressway traffic fault information collection and transmission system

Abstract

The invention discloses an expressway traffic fault information collection and transmission system comprising multiple traffic fault collection and release networks formed by multiple traffic fault collection terminals, a traffic fault release terminal and a monitoring computer. Each traffic fault collection terminal comprises a DSP (digital signal processor) module, a first voltage conversion circuit module, a first ZigBee wireless communication module, a data storage circuit module, an RFID card reader module, a CCD camera, an early warning lamp and an anti-fog lamp. The traffic fault release terminal comprises an ARM microcontroller module, a second voltage conversion circuit module, a second ZigBee wireless communication module and a GPRS wireless communication module. The expressway traffic fault information collection and transmission system has the advantages of novel and reasonable design, quick response, convenient use and operation, high reliability and complete functions. The defects and shortcomings in the prior art, for example, fault treatment and early warning are inconvenient, response is slow, warning and prompt information cannot be timely sent to subsequent vehicles, are solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic systems, and in particular relates to a highway traffic failure information collection and transmission system. Background technique [0002] With the progress and development of intelligent transportation systems, people gradually realize the importance of transportation for daily life and urban construction and development. More and more researchers integrate advanced technologies and means into the field of traffic management and control, hoping to To optimize and improve urban road traffic conditions, traffic fault detection is an important part of it. At present, the traffic fault detection methods existing at home and abroad can be divided into two types: automatic traffic anomaly detection (Automated Incident Detection, AID) and non-automated traffic anomaly detection (NonAutomated Incident Detection, NAID). AID usually uses an automatic road anomaly detection algorithm to dete...
