摘要
介绍了采用嵌入式微机SC-12和USB接口芯片FT245BM的智能控制终端,它具有3种灵活的数据接口方式:以太网、USB和RS485串行口。通过以太网连接可以实现灵活的远程数据获取与控制;通过USB串口总线,可以方便地进行现场数据的存取和设备的调试;而通过RS485总线可以使得一个嵌入式微机SC-12与40个挂接在总线上的控制模块进行通讯。
This paper presents an embedded controller of SC-12 and the USB chip of FT245BN used in an intelligent control terminal,which has three sorts of data access interfaces:ethernet,USB and RS485 serial port.To realize remotely controlling and acquiring data,the system adopts the intranet communication.In order to realize the debugger of facilities and the access of the intelligent control module data,the system adopts the RS-485 series.At the same time,one embedded controller of SC-12 can make communication with 40 general control modules through the RS485 series.
