Intelligent Meter Reading System Based On The Improved Real-time Kernel And LwIP Protocol Stack

Intelligent household is based on the residence and buildings, using of the Internet of Things technology, network communication technology and automatic control technology. The facilities related furniture combine to build a platform of family information management and control with high availability. As an integral part of intelligent household industry, intelligent meter reading system is particularly important. At present, the meter reading system society had just realized the automation and there are still two important problems are not solved. The network construction cost is higher, and the data acquisition is not intelligent. The second problem is the information solutions are not intelligent, need to rely on server resources of company.This dissertation gave a brief introduction of the concept of meter reading system, the key technology, the domestic and foreign research situation and the application prospects. It describe the problems of the current meter reading system in data collection and information solutions in detail. This dissertation describes the new scheme of meter reading system with data acquisition platform and information platform.In the data acquisition platform, this dissertation presents an improved scheduling algorithm based on the coprocessor and time slice rotation. A new real-time scheduling kernel formed by the algorithm is transplanted in the handset and base station of the data acquisition platform. Experiments show that the proposed kernel has better performance.In the information platform, this dissertation presents a solution Include a Web server with LwIP protocol stack and an Android application. This solution can set up a smart home information management control platform with high availability, provide information service for the users of intelligent terminal effectively.
