Beidou satellite based vehicle integrated control system with four-layer architecture and control method

Abstract

The invention relates to a Beidou satellite based vehicle integrated control system with four-layer architecture. The vehicle integrated control system comprises an air-land road vehicle measurement and control network layer, an air-based road vehicle remote telemetering and control layer, a land-based road vehicle broadband information transmission and control layer and a wireless sensor network system layer at a road and vehicle measurement and control part. A control method provided by the invention comprises the following steps: (a) arranging devices; (b) collecting coordinates; (c) acquiring operation state information; (d) judging a wireless communication state; (e) performing wireless network transmission; (f) performing Beidou data transmission; (g) making a decision by a control center; and (h) performing ground vehicle control. According to the vehicle integrated control system and method provided by the invention, in the situation of normal wireless communication, data is transmitted through a wireless communication network, thereby achieving the effects of low cost, a large amount of transmitted data, safety and reliability; when a ground communication network is damaged or has no signals, the transmission is performed by a Beidou satellite, thereby ensuring continuity of information transmission and being conductive to performing uninterrupted monitoring and control on operation states of vehicles.

Description

technical field [0001] The present invention relates to a vehicle integrated control system and method based on the Beidou satellite four-layer architecture, and more specifically, to a vehicle integrated control system based on the Beidou satellite four-layer architecture that can continuously monitor and control the running state of the vehicle.

Problems solved by technology

[0002] The ice and snow disasters and earthquake disasters that have occurred in recent years have caused large-scale road blockage and damage, and also caused large-scale damage and failure of wired and wireless communication facilities. If the disaster occurs, if the communication cannot be carried out smoothly, it will seriously affect the smoothness of the rescue work. conduct

In addition, in areas such as the west with a vast area and a poor basic communication environment, based on the existing communication methods, it is impossible to monitor and control the running status of vehicles, and it is impossible to solve the safety control problem of transport vehicles such as "two dangers and one passenger".

The current GPS / GSM vehicle positioning and communication mode has exposed fundamental technical defects, and will lose its due role in many cases. technical requirements
