一种实现RS232接口一对多通信的方法

An Implementation Method of One-to-many Communication with RS232

RS232是一种应用广泛的串行通信接口,但传统的RS232只允许一对一通信,这种通信方式在复杂的设备中经常不能满足使用要求。针对此问题,提出一种实现RS232接口一对多通信的方法,并论述了详细的硬件和软件设计方案。该方法经过不断改进,成功地解决了通过密闭设备的一个物理接口与设备内多个RS232接口通信的难题,并在工程中得到了实际应用,拓宽了RS232的应用范围。

RS232 is a widely used serial communication interface. However,traditional RS232 only allows one-to-one communication. Generally, this point-to-point communication method can not meet the needs of complex equipment. To address the issue, an imple- mentation method for one-to-many communication is proposed, and the detailed design of the hardware and software is described. Through continuous improvement,the method addresses the challenge of communication betwwen one physical interface and multiple RS232 interfaces inside a closed equipment. The design is used in engineering practice,which broadens the application scope of RS232.
