摘　　要：现有的Modbus测试软件无法满足我司继电保护产品Modbus通信测试需求,为此,根据公司继电保护产品Modbus通信特点,利用QT开发了一款Modbus通信测试软件。软件基于模块化设计,包括用户交互模块、通信模块和报文解析模块,利用信号与槽机制实现对通信点的查询、控制和结果显示,采用QAxObjcet类实现显示控件和Excel的互相转换,提高通信点信息配置效率。结果表明,新开发的Modbus通信测试软件能够满足我司继电保护产品的测试需求,界面设计直观,操作简单易用,具有较强的实用价值。The existing Modbus testing software cannot meet the Modbus communication testing requirements of our company's relay protection products.Therefore,based on the Modbus communication characteristics of our company's relay protection products,we have developed a Modbus communication testing software using QT.The software is based on modular design,including user interaction module,communication module,and message parsing module.It uses signal and slot mechanism to query,control,and display results of communication points.QAxObjcet class is used to convert display controls and Excel to improve the efficiency of communication point information configuration.The results show that the newly developed Modbus communication testing software can meet the testing needs of the company's relay protection products,with intuitive interface design,simple and easy-to-use operation,and strong practical value.
