Abstract

The invention discloses a device for monitoring the whole course of expressway on the basis of integrated navigation, which includes a shell and a monitoring circuit. The device is characterized in that: the monitoring circuit essentially comprises a digital signal processor DSP, a receiver GPS, an electronic compass, a twin-wheel decoder, a wireless data transmission module GPRS and a serial ports extended chip which are electrically connected; serial communication ports of the receiver GPS, the twin-wheel decoder and the electronic compass are connected with a corresponding substring port of the serial ports extended chip respectively; a maternal port of the serial ports extended chip is connected with the corresponding serial communication port of the digital signal processor respectively; a communication port of the wireless data transmission module GPRS is connected with a corresponding CAN communication port of the digital signal processor DSP. The invention can feed back the operation information of vehicle to a monitoring center in the process of vehicle operation forwardly so that the trouble and shortcoming due to passive collection of vehicle operation information by the monitoring center can be avoided and the drivers can try to avoid over-speed driving subjectively. Therefore, incidence of the traffic accidents can be greatly reduced.

Description

technical field [0001] The invention relates to the field of vehicle traffic monitoring, in particular to a monitoring device for running positions, speeds and other running states of vehicles traveling on expressways and high-grade roads. Background technique [0002] At present, the comparatively general traffic monitoring system both at home and abroad generally adopts the method of closed-circuit television monitoring and speed measurement and taking pictures. Although the closed-circuit television monitoring system can understand the traffic conditions and vehicle running conditions more intuitively, effectively and quickly: but the closed-circuit television monitoring system cannot grasp the running speed of the vehicle well, and the system consumes a lot of power, which is not convenient for long-distance monitoring. Transmission, the transmitted picture quality is poor, low resolution, strong flicker, etc. Although the mobile radar Doppler effect speed measuring and...
