【摘要】 基于VB串口通讯代码及有关水利仪器,分析了通讯端口类型、端口参数、仪器参数、命令及数据格式、交互流程和数据校验方法等数据交互内容,指出目前在数据交互领域缺乏统一的标准,导致同类仪器无法共享数据采集系统,增加了数据采集和共享平台建设难度,阻碍了水利信息技术和物联网技术的发展;提出需要统一规范的全国水利仪器数据交互内容,以适用于数据交互各环节,提高数据交互通用性。更多还原

【Abstract】 Based on VB code and some water conservancy instruments,the authors analyze data interactive content,such as the communication type,port parameters,instrument parameters,command and data format,interactive process and data checking method.There was not unified standard to standardize data interaction,which leads to similar instruments can not be shared data acquisition system,increased data collection and sharing platform construction difficulty,and hindered the development of water conservancy information technology and the Internet.The conception of the national water instrument data exchange standard is put forward,and the standardization of data interaction is carried out to improve the commonality of data interaction.更多还原
