To improve the data quality of agricultural products and realize the timeliness and the effectiveness of information release, a method of agricultural products price information acquisition and early warning system is proposed This system makes use of Google Maps application programming interface and ASP. NET technology, with mobile communication technology and smart client technology to design data acquisition module, data processing module, data release module, early warning module and managing basic data module in this system. The practicality, compatibility and scalability are guaranteed. Experiments show that the system realizes functions such as real time products price data acquisition, processing, release and early warning. This system ensures the validity and accuracy of data, solves the agricultural products information collection lag problem and accelerates the exchange of agricultural products information.%为了实现农产品价格信息采集发布的及时性和有效性,提高农产品数据质量,提出一种农产品信息采集与预警系统的设计方法.通过运用Google Maps提供的应用程序开发接口和ASP.NET技术,并集成移动通讯技术和智能客户端技术,设计了农产品信息的采集、处理、发布,系统数据的预警以及基础数据维护等功能模块,保证了系统的实用性、兼容性和可扩展性.实验结果表明,在农产品价格信息采集方面,该系统实现了农产品价格信息的实时采集、处理、发布及预警功能,保证了数据的有效性和准确性,解决了农产品价格信息采集的滞后性等问题,有利于农产品信息的快速交流.
