Elevator Control System Based On Network Technology - The Branch Subsystem Software Design

Remote elevator monitor is significant to safe work and maintain of elevator. On the basis of analyzing the technology of remote elevator monitor throughout the world, this dissertation uses technologies of network, software and embedded system to put forward the system architecture of Remote elevator monitor based on network. That system is mainly composed of embedded terminal, monitor center and filiale subsystem. Embedded terminal collects and deals with elevator information; monitor center receives elevator status signal and sends elevator commands by communicating with embedded terminal; filiale subsystem collects monitor requests of filialeusers.This dissertation mainly focuses on the design of filiale subsystem. Filiale subsystem sofiware uses B/S three layers framework, SQL Server database, technologies of ASP, ADO and ActiveX component to realize functions, such as installation, review elevator information, seal-time monitor, at-once monitor, alert monitor, data analysis, event analysis and so on. The paper detailedly describes design flow of system functions, and puts emphases on the design flow of real-time monitor, at-once monitor and alert monitor. Refering to testing technology, this dissertation brings forward a special test scheme for filiale subsystem software and also put it intopracrice.
