摘　　要：为了解决目前国内种子加工设备通用性较差,开发效率低的问题,设计开发了一套种子加工设备的通用控制系统,在硬件方面采用模块化思想设计,在软件上移植有嵌入式操作系统。为保证系统内部通信可靠,机器能够正常工作,设计了一套通信协议。通过仿真验证,在该通信协议下,接收方错误接收数据的概率大为降低。现通用控制系统已成功应用于种子风力筛选机。实践表明,该控制系统功能完善,性能优良,可以实现提高开发效率的预期效果。To improve the universality of domestic seed-processing equipment,this paper proposed and developed a set of universal control system for the equipment.To provide reliable communication for the control system,and make the system work normally,this paper designed a set of communication protocols.The simulation result shows that the probability of receiving wrong data is decreased greatly with this protocol.Now the universal control system has successfully been applied to the seed selecting machine.The result indicates that the control system can help develop the seed-processing equipment efficiently.
