Microcomputer Monitor System For Pay-for-Use Train TV

With the development of the society and the information technology,Pay-for-Use system is widely used in various situations, making people's lives more convenient.This project introduces Microcomputer Monitor System for Pay-for-Use Train TV. There are four major components in this paper as follow:the mobile Pay-for-Use host,submachine imbedded the TV player, wireless receiver, management server.In this paper, the Train TV Pay-for-Use System as the background, the main research is based on the hardware and software development of the Pay-for-Use System and the methods of safety precaution. The system using Single-chip microcomputer as the control core, improves DES encryption methods with rolling key which is making use of the random number and the IC-MAC address. This system solves the problem of communications serurity between the Pay-for-Use system and the submachine to prevent the illegal actions.After the testing of the hardware and the software, it's proved that the whole scheme of the system presenting in this paper is available and valid.The system solves some of the drawbacks of the traditional charging models, and also suitable for other Pay-for-Use places as well.
