中文摘要：

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.

英文摘要：

Importance of field observations is increasing for scientific research and accurate forecasting.Traditional wired,wireless,or mixed data transferring approaches are generally limited in use due to their possible high costs and construction complexity.They also might face technical issues such data redundancy,error correction and signal interference etc.In this paper,a data acquisition system for near real-time field observation based on Twitter-like services and GSM/SMS network is proposed,in which observation data will be sent to a Twitter service via GSM/SMS,and then be acquired by a client application that can be easily implemented to access the Twitter service with REST APIs.In a more practical case,the client application can be a data center,which will digest data into their large database via Twitter and serve them to public together with other data.The proposed approach,in comparison to traditional ones,is characterized by lower cost,high efficiency,more flexibility and capability of rapid development,and is suitable for scientific data collection,which requires a near real-time data update frequency and low data security.
