Research About Optic Power Meter Of Network

With the development of the microelectronics technology, embedded-system is adopted in the fields of the family and the industry, etc. But embedded-system is generally outside of the Internet. In the modern society, Internet has become one of the important basal communication establishments. People are used to browsing all kinds of the information via Internet. So it has become a more and more important how to connect the embedded-system to Internet.This thesis is about how to connect the embedded-system to Internet. I design the Optic power meter as the embedded-system. The mini controller of the Optic power meter is TI' s TMS320vc5410A. We design relevant hardware and software to meet the performances that the Optic power meter demand. From many means , we select the means that using net interface card chip to connect the Optic power meter to internet. This means is support by high speed microprocessor and embedded-system.With Lhc development of the microelectronics technology and digital signal process technology, the performance of DSP has been highly enhanced and the price has been reduced. Especially with the development of science and technology, structure and control algorithms of intelligence system is more and more complex. Traditionally we use PC to complex compute and simply control. And we use single chip processor to simply compute and complex control. The traditional structure is collapse. And the new structure is established. The new structure is that using high speed information processes in local and using PC as the controller in global. Another new structure is that mainly using high DSP to deal with the core complex compute and embedded control system. As long as the development of the internet, the problem that integrate the internet and embedded system is acute. This article study that how to embedded the internet into DSP system.First, the article introduces the DSP technology and thedevelopment of the signal chip nets. Comparing the existing net projects, the article adopts a project that adds the embedded TCP/IP for DSP system to reality embedded internet. Second, the article analyzes the Ethernet protocol, ARP, ICMP, IP, UDP, TCP etc. Basis of the demand of the DSP technology, the article proves the algorithms of these protocols. Ensuring compactable to the protocols, the article edited the traditional algorithm. And we test all the edited embedded TCP/IPS. At last the article analyzes the HTTP and presents a new method to realize the embedded web in DSP system.
