PLC与GPS接收器通讯及定位数据采集技术设计

摘要

Global Positioning System has been extensively used in the world. In this paper a control system based on PLC technologies is designed which uses a RS-232 interface to communicate with a GPS receiver. By analysing the mode of work,the principle of work and data standard, a mathematic model is developed to provide automatic control,real-time analysis and computing. The system collects data by the technology of PLC and communication. The data can be applied in all kinds of automation systems which need position information.%通过设计基于PLC技术的数据采集系统和相应的算法,利用RS-232接口与GPS接收器进行通讯,完成实时分析和计算,自动采集GPS接收器采集到的位置信息.该系统通过以PLC核心控制器,利用通讯、数据分析技术等实施数据采集和利用,获得的定位数据可广泛应用于各类有地理位置信息需求的自动化控制系统.
