| 摘 要： | 基于国内最新型的智能收发器FT3120,设计成采用HOSTBASE结构的新型智能节点的方。利用双口RAM(CY7C026)芯片成功地解决了将下位机数字信号处理器(DSP)控制信息传送到上位节点,而该节点又可将信息通过Lonworks现场总线发送给中央控制机系统,系统的信号传递由于是双向的,所以该节点系统可以通过总线完成数据的智能上传和上位机对下位节点智能编程,它具有智能在线编程控制(IC)的先进特性。通过研究和分析表明,该系统具有广阔的推广前景。

| Abstract: | A late-model intelligent node is designed which based on the update Smart Transceiver FT3120. The special characteristics of the FT3120, and then design a intelligent node system which is in a HOST BASE configuration and can be used in the Lonworks field bus control network. It includes the recent Smart Transceiver FT3120. dual-port RAM CY7C026 and Digital Signal Processor TMS320LF2407A. The lower level state information of the DSP control can be transmitted to the higher level intelligent nodes through the dual-port RAM. And the center IPC control system could send some programs to any intelligent nodes in the Lonworks. The system has good prospects. |
