The Embedded Remote Monitor And Control System Based On Ethernet

At present , to combine the embedded system with the intellectual node that can link with network is a hot research focus in many research fields including automation control, communication, computer science, etc. The system can be constructed by complicated and expensive industrial real-time control equipments, or the intellectual electrical home appliances of small size and low cost.Job of this paper devoted to transplanting the RTOS uC/OS-II and the TCP/IP protocols to the 51 serial MCU platform. Such a system is established by Winbond's W5168EBP MCU with built-in 64K programmable flash memory, 32K expanded data memory and Ethernet network interface control chip- RTL8019AS.The most remarkable strength of this system is having realized the HTTP protocol on the 8bits MCU platform. After the system has been configured correctly, it will be a node with independent IP address in the Ethernet. Then any PC inside the same network can visit the system as a website through IE browser without any special software or hardware. You can input this IP address into the address bar of the IE browser, then you can visit the hypertext page stored in the system, through operating the control button on the page directly, the I/O output level of the MCU can be changed according to your operation.The purpose and the value of such a system are:1 The originally isolated control node will be transformed and can be merged into automation control network and information network.2 The TCP/IP protocols are open and free, it is not controlled by a certain manufacturer. It makes possible to develop the system with independent intellectual property right.This paper focuses on the following aspects:1 Transplanting the uC/OS-II RTOS to the specific platform;2 Realizing part of the TCP/IP protocols according to the system demand .The most remarkable point is the realization of the HTTP protocol in an 8bits MCU platform; 3 Researching EMC of hardware system design and ability technology design of software .4 Analyzing the system's real-time performance with data from experiment, finding out the most important factor that determines the real time performance; And researching on Performance Testing of the Embedded System.5 Applying the system to the Simulation Research on Joint Operation of Multiple Power Generating Method in Marine Power Station on the fields of network communication and remote control.
