摘　　要：以某消声水池研制为基础,由与编码器之间的通信,结合理论知识,在总线匹配、网络连接方式和接地等问题上,对RS-485串行总线通信问题进行了详细分析。综合考虑消声水池现场的实际限制因素,给出了硬件相应解决方法和软件通信实现开发方面需注意的问题,再予以验证,有效地提高了其通信的可靠性。Based on the development of the anechoic pool,this paper makes a detailed theoretical analysis on the communication of RS-485 serial bus on issues ranging from bus matching,network connection to ground connection which communicates with the encoder.Taking the practical limiting factors of the anechoic pool into consideration,the problems in the practical design of hardware's solutions and the implementation of software communication are also discussed in detail and then proved,which effectively improves the reliability of its communication.

关 键 词：消声水池 RS-485 总线 软件通信实现
