The exploration on the network supervision system of the signal equipments in the QingZang Railway

This paper makes a simple analysis of the network supervision system of the signal equipments and gives a proposal about how to improve the system's structure depending on the special geography condition and the air condition. The supervision system has to expand its function and scale to meet the requirements of the customers. The improved system should have high expandability and maintainability, and increasing the productivity of software. In order to satisfy these requirements, a new computer system based on autonomous decentralized system (ADS) architecture, was introduced. The paper explores the structure of the system's hardware and analyzes some problems you should note in software design.
