Remote Online Update And Maintenance System Design Based On Intelligent Instrument

With the computer of development, Embedded system that is a new technologyappears on in order to meet people’s needs. In recent years, the development of embeddeddevices has penetrated into every aspect of people’s life, we have mobile phone, tablet,computer, and have satellite communications, the Shenzhou spacecraft launch, missilelaunch and so on. Has now become the most widely used flied.Currently, with embedded industry intelligent instrument upgrades and maintenance ismore and more quilkly, a new electronic product are generally released during a litterperiod or products that have been applied for the maintenance require the relevant technicalpersonnel to the scene for debugging, which increases the cost of investment. And with therapid development of network technology, network communication has become a stageduring which people communicate, an essential part of a network for a bettercommunication system can give individuals, to businesses to bring endless benefits.The subject is proposed based on the device’s remote online upgrades and maintenance,in order to reduce the cost of products late research conducted in the Internet networkcommunication.To achieve online upgrade equipment and upgrades, network communication isinsurmountable, so here there is a learning network protocol layers and applications, aswell as the preparation of the application layer protocols. Network communication, C/Smodel has been applied in most network programming, so here it is used to build theserver and client data reception. Moreover, network traffic is now the most important thingis not transmitted, but the network security, the encryption and decryption of the data it isessential. Finally, the data received was used for equipment upgrades and maintenance.
