【摘要】 在水利水电监控系统中,现场级设备常采用串行口与现地控制单元通信,实现数据交换。为了有效管理通信,现地控制单元一般使用有扩展能力的专门系统。串行口通信管理模件就是这样一种有通信管理能力的嵌入式系统。介绍了串行口通信管理模件的功能和特点,详细分析了基于VxWorks嵌入式实时操作系统的串行口通信管理模件的软件设计。更多还原

【Abstract】 In Hydropower Plant Monitoring and Controlling System,serial port was often used to communicate the field level equipment and Local Controlling Unit(LCU) to achieve data exchange.To manage the communication effectively,a specialized system that has capacity of Scalability was used in LCU.Serial Port Communication Management module was such an embedded system with the ability to manage communication.A detailed analysis of the software design of the serial port communications management module based on VxWorks RTOS was introduced,and the introduction of the functions and features of this module were included also.更多还原
