摘　　要：具有UDP广播通信功能的以太网通信模块在监控报警等系统中应用广泛。但由于以太网的固有特性,以太网通信模块在实际应用前通常需要根据用户实际需求,进行IP地址等参数的重新配置,因此设计一款具有UDP通信功能且参数配置灵活方便的以太网通信模块是一项具有重要现实意义的工作。为此,本文以微处理器C8051F340与以太网控制器CP2200为核心,设计了一款以太网通信模块,并给出了此模块的软硬件设计及部分相关代码。该模块不仅可实现以太网UDP广播通信,而且可利用USB接口和PC机LabVIEW程序实现模块参数在线配置,同时具有结构简单、配置方便、成本低廉的特点,并已成功应用于纺织厂与武警信息系统。Ethernet communication modules with the function of UDP broadcast communication are widely used in surveillance and alarm system.Due to the intrinsic characteristics of Ethernet,Ethernet communication modules usually need configure IP address and other parameters according to the actual needs of users before practical application.So it is a work with important realistic significance to design Ethernet communication modules which have UDP communication function and flexible and convenient parameter configuration function.Thus,an Ethernet communication module is designed based on microcontroller chip C8051F340 and Ethernet controller chip CP2200,and more detailed information about hardware design,software design and correlative program codes is given in the paper.Using the communication module,users can realize not only the UDP broadcast communication,but also on-line parameters configuration using USB interface circuit of the module and LabVIEW program in PC.At the same time,the module＇s characters such as simple structure,convenient setting and low cost are exhibited,and it has been used in textile mills and information system of armed police.
