[Abstract]:According to the need of continuous position data acquisition, a mobile intelligent monitoring system is developed to realize the control of the intelligent vehicle and the real-time monitoring of the surrounding environment. The system is mainly composed of the upper computer system. The communication system and the lower computer system are composed of three parts. The communication system consists of two ZigBee modules. The lower computer system is composed of intelligent vehicle arm development board and GPS module. The system is based on point-to-point communication of ZigBee2007 protocol, with CC2530 chip as the core and intelligent vehicle as the carrier. The ARM11 microprocessor is the master processor of the lower computer. Effectively reduce the number of ZigBee static nodes, thus reducing the cost of monitoring; With the use of static fixed collection points, it is more convenient to carry out omnidirectional and accurate monitoring. The main research contents and results of this paper include the following aspects: 1) the research status and significance of embedded Linux system, wireless monitoring and intelligent vehicle are summarized, and the shortcomings are analyzed. The research significance of this subject is explained by comparison. 2) according to the research goal of this subject, through the analysis of CPU performance requirements and the comparison of various wireless communication modes, the wireless monitoring implementation scheme based on ARM6410 and CC2530 is put forward. 3) complete the overall scheme of the system and the design of each functional module, including the selection of hardware, the method of software implementation, the design of wireless communication, etc. Build the embedded Linux system platform, complete the related system, drive, application and other software development. Build the ZigBee communication platform software and hardware system. The communication between upper computer and lower computer is realized. 5) the control interface of upper computer is developed, the whole device is debugged and tested synthetically, and the information exchange between intelligent vehicle and control interface is realized. The wireless monitoring system of intelligent vehicle based on embedded ARM-Linux proposed in this paper is also a simulation of modern driverless vehicle monitoring system. Dangerous operation items, and large-scale intelligent driving can not only increase the security of driving, but also be an inevitable application in the future intelligent field.
