一种232转红外的电路设计

Design of circuit to turn digital signal to infrared pulse through 232 serial port

在现代电子行业中无线通讯技术的应用越来越广泛,红外通讯作为无线通讯的一种技术备受各个领域的欢迎。而在实际通讯使用中,采用串口通讯占据着大量的工业市场,尤其是在电能表行业,红外通讯已经成为新型电子式电能表必不可少的功能之一。设计可靠的电路实现PC机的232串口转红外工具,完成电脑232串口转红外的通讯,实现对产品的实时操作。在此主要介绍一种简单便捷的电路设计来实现串口转红外技术。

The wireless communication technology in modern electronics industry is widely used. The infrared communica-tion as a technology in wireless communication field is paid close attention. In actual communication application,serial commu-nication occupies a large number of industrial markets,especially in the energy meter industry,infrared communication has be-come one of the essential functions for new type of electronic meters. Reliable circuit design to achieve PC’s RS232 serial port instrument to turn digital signal to infrared pulse can complete infrared communication through computer RS232 serial port and realize real-time operation of the product. A simple and easy circuit design technology for implementing the conversion is de-scribed in this paper.
