Circuit switch data transmission service 线路交换数据传输服务
The author designed the logic circuit to control the synchronous & asynchronous signal switch and other logics used by FPGA, realized the data exchange between the host computer and Smart-Communication Board used by the Dual-Ported RAM, and finally designed a high-speed Smart-Communication Board. 设计中用FPGA来实现同异步的转换以及逻辑控制电路,并用双口RAM来实现上位机与智能通信板的数据交换,设计出一种高速的智能通信板。
Hardware circuit design included analog input-output channels, switch output channel and relevant choice of hardware, including the sensors, frequency converter, data acquisition card, and etc. The development of the software was introduced and the program was worked out in detail in the paper. 硬件电路设计,主要包括模拟量输入、输出通道,开关量输出通道等的设计及相关硬件的选择,包括传感器、变频器、采集卡等:详细介绍软件的开发与编制;
