With the increasing number of city vehicles, traffic neodymium magnets congestion has become a worldwide concern. In order to effectively alleviate the traffic blocking
Plug, car navigation information terminal system has been more extensively studied. This thesis solar panel powered car navigation terminal
For the study, research center based dynamic navigation and car navigation terminal solar-powered car key technologies, covering
Motor control, power electronics, wireless communications, artificial intelligence, geographic information systems and database technology and other subject matter.

Major research paper as follows:
(1) system introduces the concept of dynamic navigation information systems and solar-powered car servo
Service system development and research status.
(2) type in the center of discussion of the basic principles of dynamic navigation system, the system results
Structure and main functions, based on the analysis of several key vehicle dynamic navigation technology, research and design of the vehicle unit and navigation server
Communication between the http://www.chinamagnets.biz/Neodymium/Ball-Neodymium-Magnets.php protocol with reference to the NTCIP standards, in line with central computer to the ITS field device communication protocol (C2F) interchangeability, each
Operational requirements.
(3) large-scale urban road network in order to obtain traffic information, to achieve a transport speed based on FCD
Degree of estimation, the realization of dynamic navigation data sources; proposed a modified Dijkstra path search algorithm is adopted
Arc with a map - arc structure that network structure, and relationships through the arcs of certain restrictive storage network traffic information and a priori information
Improve the search efficiency, solve the city's road network traffic information is difficult to express the restricted problem.
(4) servo system for solar energy,
In the analysis of permanent magnet synchronous motor (PMSM) based on the mathematical model to study the neural network control and fuzzy control technology in the PMSM control
System applications. Neural network were discussed in direct control, neural network predictive control and fuzzy-PI control strategy in the PMSM control
Control and Matlab / Simulink platform, built on permanent magnet synchronous motor and controller model.
(5) Discussion
Solar intelligent navigation on the car terminal, the servo system structure and implementation methods, and the establishment of a permanent magnet synchronous servo motor fuzzy PI control
Controller simulation model, based on adaptive connection weights based on the revised fuzzy controller PI regulator and the different control values, with
When completed the PMSM controller software and hardware design, and conduct the relevant tests and testing.
Relevant experimental results show that, on
Wen made the center of the traffic information collection Dynamic navigation and path planning algorithms, as well as permanent magnet synchronous motor servo system design
And the method is effective and feasible, to meet the requirements of vehicle intelligent terminal, a solar-powered car for the dynamic navigation terminal of the push
Wide and used to provide a theoretical basis. Degree Year: 2009
