摘要
串行通信接口技术以其硬件设计简单、控制方便、成本低廉、传输距离远等优点在工程中广泛使用。详细阐述了目前比较流行的RS-485,RS-232串行通信接口在实际工程中的设计方法,同时以基于串口通信的磁特性测量系统为例给出了串口通讯设计和使用的方法。最后对设计中的存在的问题进行了分析,为实际工程中串口通信技术的应用提供了一套完整的解决方案。
The serial communication interface has many merits such as simple design hardware, more convenient control, lower cost, far transmit distance and etc. So it is widely used in many engineering projects. The paper introduces methods of designing the serial communication interface in practical engineering based on RS -485 and RS - 232 serial communication interfaces and gives a design and a using method of the serial communication interfaces based on the example of magnetism measuring system. In the end, the paper analyzes the existing problems in design, gives a set of solution for the serial communication interfaces in engineering projects.
