摘　　要：河流流量测验与成果管理系统(ITMS)实现了从流速仪测速信息来源性采集到加工处理,自动完成断面测验和分析计算、成果整编工作,由便携式计算机支持测验作业,把传统的测验模式提高到信息化的测验水平。其中的软硬件接口设计是系统目标能否实现的瓶颈,在简单介绍整个系统功能的基础上,对计算机COM端口读写与施测过程设计的成功方法和经验进行叙述,给出了详细的端口通讯协议,可供用户自行研发其它各种工作原理下的流速仪测速信号装置与之配套。Rivers flow test and ITMS achieved from the acquisition of the current meter speed information source to processing,automatic completeness of section test,analytical calculation and the results of compilation. They are supported by portable computer test performance,increasing the traditional test pattern to the informationization level. The interface design of the software and hardware is the key of the realization of the goal. In this paper,based on the brief introduction of the whole system function,the authors described the method and the experience of computer COM port and the measuring process design. Besides that,the authors gave the detailed port communication protocol,available for users to develop other kinds of work under the principle of current meter speed signal device to match.
