USB接口微型无线串口设计

RS-232是异步通信中应用广泛的通讯协议之一,广泛应用于终端设备之间的相互通信。无线通信取代有线通信是技术发展的趋势,小巧精致便携是技术应用的需要,为此,文中利用主流USB接口加无线通信技术,开发出简单实用的USB无线串口。介绍了USB接口微型无线串口的制作方法,尺寸仅为54 mm×18 mm,体积小巧、携带方便、传输距离＞100 m、性能稳定可靠,可广泛应用于各种实际场合。

Design of Mini Wireless Serial Communication with USB Interface

RS-232 is one of the widely used communications protocols in asynchronous communication.It is widely used in the communication between terminal equipment.The replacement of wired communication by wireless communications is a technical trend,which requires compact and portable applications.To this end,the article develops a simple and practical compact USB wireless serial port using the USB interface of the mainstream Canadian wireless communications technology.The miniature wireless USB interface serial production methods are presented.The interface by the methods has the advantages of small size(only 54 mm×18 mm),great stability and a transmission distance greater than 100 m and therefore can be widely used in various practical situations.
