介绍了以太网控制器芯片RTL8019AS并将TCP/IP协议嵌入单片机PIC16F877中,以便能够和Internet交互数据,下位机把采集到的温度水位信息通信给上位机,并在触摸屏上显示,再将数据远程通信到生产厂家,以便生产厂家对所卖出去的产品进行实时监控和及时维修。给出了系统硬件原理框图和有关实现TCP/IP协议的程序代码,对系统的软硬件架构做了阐述。
Introduces the Ethernet controller chip RTL8019AS and TCP / IP protocol embedded PIC16F877 microcontroller, in order to be able to interact with the Internet data, the next crew to collect the temperature and water level communication to the host computer, and the touch screen display, and then remote data Communication to the manufacturer, so that manufacturers on the sale of products for real-time monitoring and timely maintenance. Given the system hardware block diagram and the program code to achieve TCP / IP protocol, the hardware and software architecture of the system are described.
