Based on embedded Linux remote update design and implement
ABSTRACT
Along with the technical fast development and extensive universalities of information and networks, the people's need to the Internet is also more and more big, the advantage that Internet bring also gets materialize more and more now, make equipments, such as many information appliances and the intelligence appearance... etc .connect go into the Internet to make possible, thus carry out the network to turn, the centralized management that intelligence turn, bring the people the more fascinating and more convenient life style.
Considering that the demand of electric power is increasing ceaselessly in recent years, and the supply become more and more embarrassed. In order to assure the safety of the electricity supply and put the running of electricity into a right commercial way, a powerful and exactly computing system to gain the data automatically is essential.So,it also need to design a system to make it update automatically. This paper is considering how to design and implement the remote update system which based on the embedded Linux.
Updating system by manual work exist two disadvantage.First,it must waste a lost of manpower and time.Second,manual work usually make mistakes, to be contrary, the computer can make the work much more efficiently and correctly. This subject is studying how to implement the remote update of data collect system by the application. this paper detailed discusses the thought of the system analysis, and the implement of the system function, and the principle of continue transferring from breakpoint which make use of the stipulations of an agreement designed by myself. At the same time , it also introduce the multithreading design, simply encrypt and compress method and so on.
Keywords: long-distance update, multithreading design, continue transferring from breakpoint
