野外实时数据对于研究和预报工作越来越重要,传统的有线、无线或者混合数据传输方案往往建设难度大、成本高,且需处理数据冗余、信息纠错和信息干扰等实际问题.实验基于当前流行的类Twitter网络服务和GSM短信息服务,提出了一套基于无线短信的满足近实时数据获取要求的水文野外数据获取系统,并对其进行初步试验.方案具有低成本、高效率、构建灵活快速等特点,可以被广泛应用于近实时、保密性要求低的科研生产领域数据采集业务.
Field real-time data is more and more important for research and forecast work, and the traditional wired, wireless or hybrid data transmission schemes are often difficult to build and costly, and need to deal with the practical problems of data redundancy, information error correction and information jamming.Experiments are based on The current popular Twitter network service and GSM short message service put forward a set of wireless field-based data acquisition system based on wireless short message to meet the requirement of near real-time data acquisition and preliminary test.The scheme has low cost, high efficiency, build Flexible and fast, it can be widely applied to the data collection business in scientific research and production field with low real-time and confidentiality requirements.
