基于短信息的农业生产过程数据采集系统

Data Acquisition System of Agriculture Production Process Based on Short Message

目前的GPRS/CDMA无线监控系统一般采用TCP/IP或UDP模式进行数据传输,适用于数据量大、速度要求高的场合。针对农业生产分布范围广、监控参数变化缓慢的特点,本设计利用移动通信网络的短消息业务,通过CDMA1X无线模块实现Linux监控中心对各现场数据终端的无线数据采集和控制,大大降低了数据通信的费用,适用于大面积的农田、鱼塘或森林等的数据监控管理。

Most of the data transmissions of GPRS/CDMA wireless monitoring systems were used TCP/IP or UDP mode,which are fit for great quantity and high speed data transmission.The production of agriculture is widespread,and the monitored parameters usually change slowly.Based on the short message service of mobile communication network,with CDMA1X DTU,wireless data acquisition and control of the monitoring center which runs Linux to field data terminals are realized.The expenditure of data traffic was dropped down by the design,which could be applied to the data monitoring and management of farmland,stew and forest.
