Research Of Pumping Station Temperature Monitoring System Based On Embedded And Field Bus Technology

With enhancement of pumping station automatization, the development of embedded microprocessor, network communication, field bus technology, made pumping station remote monitoring system enable. In this paper, we realize the remote monitoring system of pumping station with embedded Internet technology and field bus technology at same time.Firstly, in this paper, we introduces the development of monitoring control system,embedded operation system,embedded Internet technology, field bus technology both here and abroad. The second part of this paper bring up the whole scheme of this pumping station temperature monitoring system and recite the mission of each part at same time. The third part of this paper we explaint the kernel structure ofμC/OS-II and describe the procedure about how to portingμC/OS-II on high speed SOC microcontroller C8051F040, the OS is the based of carrying out embedded WEB server. The fourthly part of this paper introduces hardware circuit of embedded WEB server,analyses some standard Internet protocols like Ethernet,ARP,IP,ICMP,UDP,and TCP,describe the hypertext transport protocols HTTP in detail and realize a embedded WEB servers at same time. The fifth part of this paper recite main content of CAN bus in detail and bring up hardware circuit of CAN node in the system, as well as,introduces software implementation of CAN corresponding. The sixth part of this paper introduces the hardware circuit of field detection part and software implementation of this system in detail. At the end of this paper,we summarize all the work which has done ,what's more, do some expectation the technology about pumping station remote monitoring system.
