河工模型数据通信协议的智能化识别方法

Intelligent Identification of Communication Protocols for Data of River Model

河工模型试验测量参数多、仪器多,数据交互难度大,为此,建立了数据库的通信协议智能化识别方法。将功能码和数据码分别存储至对应数据表,数据采集时打开相应功能码表调用命令,发送给对应仪器;同时,接收仪器返回数据,再打开数据码表进行数据解析,从而实现不同通信协议仪器的数据交互。以赣江南昌段河工模型为例,运用智能识别方法采集流速、水位等数据,试验结果表明,该智能化识别方法可准确完成不同仪器数据采集,简化了数据交互程序,提升了上位机应用系统通用性和生命周期。

Because of large numbers of measurement parameters,instruments and communication protocols,it is difficult to solve the problem of data interaction,a kind of communication protocol of intelligent recognition method is established based on ACCESS database. The method is used to manage instruments and communication protocols. The command function code and data code are stored to their corresponding data table frame. The corresponding functional clock is called through database field command when data are collected,and then sent to the corresponding instruments. At the same time,the receiving instrument returns data,and the returned data shall be carried out in accordance with the corresponding communication protocol for data analysis. It realizes the interaction of different communication protocol data. The flow velocity and water level data are collected by using the intelligent recognition method in Nanchang section of Ganjiang river. The testing results show that the intelligent identification method can be accurate to complete data collection,simplifies data interactive program,strengths application system of PC and the life cycle.
