Abstract

The invention relates to a road transport comprehensive monitoring early warning system. The system comprises an embedded type industrial computer, a PC extension piece, an ADAM card, a displayer, sensors for collecting on-road running information of vehicles and dangerous goods, a GPS module and a GPRS module, wherein the sensors are arranged on the dangerous cargo carrying vehicle and dangerous goods containers, the signals collected are transmitted in a wired or wireless mode to ADAM module ports; all ADAM modules are connected in series; the ADAM modules, the GPS module, the GPRS module and the displayer are communicated with the industrial computer by RS232 or RS485 serial ports. The system of the invention monitors, identifies, diagnoses and evaluates relative signal indexes to judge the dangerous states of the dangerous cargo carrying vehicle and the dangerous goods containers, thereby realizing the early warning for the road transport of the dangerous goods as well as the active remote control in the particularly emergent state.

Description

Technical field: [0001] The invention relates to a road transportation comprehensive monitoring and early warning device, that is, a vehicle-mounted system that integrates information collection, information processing, monitoring, early warning, and communication. It can be used for road and road vehicle management, and is used for vehicle managers, drivers, and monitoring centers. , Cargo comprehensive monitoring, and provide early warning function, especially suitable for road transportation management of dangerous goods, belonging to the technical field of road transportation management. Background technique: [0002] At this stage, the main technical means for road transportation management of dangerous goods are GPS tracking and positioning and vehicle driving recorder. The main characteristics of these two technical methods are: GPS can only send back vehicle location and speed information to the monitoring center, and the information recorded by the vehicle driving record...
