Application Research On LONWORKS Fieldbus In Automatic Parking System

With the growth of economy and development of Urbanization, Automobiles have been increasing gradually in people's life, but the communication construction behind it, leading the situation of traffic congestion getting worse and worse. As the biggest developing Country, there is no time to wait to solve the problem of traffic congestion, especially improve the Parking system to ease the problem of Parking. Then, we should learn from foreigner's experiences, combining our own situation of city traffic, vigorously developing the machinery Parking, at the same time, an effective management system must be constructed, only in this way, the Parking situation in our Country will be improved.This paper firstly introduces development of fieldbus at home and abroad, emphases the characteristic of LonWorks, on the basis of this, expatiate on the Research significance in detail. By analysis on tranditional control method, comparing the traditional control method in Machinery Parking with the LonWorks control system, giving prominence to the advantages of LonWorks. Then, design the hardware of the key module base on 3510 chip in detail and show the work performance of 1212D. In the design process of system software, according to the scene, the control system was divided into two types: one motor control some car boards, one motor control one car board. We establish control models according to the actual situation, and program of these control models. As the function of the up module and the down module is different, program the applications separately.Last, install nodes of the network system and debug them. During the debugging, according to different debug needs, use three different methods to monitor, and cite some problems during the debugging and those solutions...
