City Intelligent Public Transportation Arrgeand Management System Vehiele Terminal Key Technology And Realization

Along with the strategy for pubic transport priority was confirmed, public transport plays more and more important role in relieving traffic congestion.Compare with the need, the urban public transport has a great difference in our country.The public transport intelligentize is a important devlopment direction for public transport and a important means to enhance radically the public transport service level.The data of public transport vehicles and passenger flow is a base to establish dispatching scheme, obtaining passenger flow data timely and correctly to come true the real time and dynamic public transport dispatching,put forward higher request for the intelligentize of bus carring equipment.To find the dispatching scheme answering for the situation of our country yet has many works to do.Firstly beginning with the researching general situation both at home and abroad,the paper introduces the researched content,target and method in brief; Secondly, it analyzes the hardware and software arehiteeture of embedded terminal; it shows the anaiysis and design for the component of embedded pplieation.The software and hardware components of the system and the function of each component in the system are researched.Then the key technologies of the GPS-GPRS Vehicle Monitoring System are studied.this paper introduces GPS global position technology , GPRS(General Packet Radio Service)technology. the iniroduetion of GPRS technology includes the development of GPRS, the advantages and shortcomings, and problems existing in GPRS.
