Elevator The Trapped Ladder Appease System Design And Implementation

Elevator of modern architecture is one of the most common kind of vertical transport vehicles, it is People's Daily life, at the same time, provides the convenience for people to save time and energy. But because of elevator control system and structure is complex, so to ensure the safe operation, monitor elevator status and fault management, supervision, become elevator maintenance and operation safety of urgent need, at the same time, along with the development of technology of telecommunications, GSM/GPRS technologies are widely used in various fields.This article is divided into six parts. The first chapter is an introduction, it analyzes the domestic and foreign similar researching situation and existing problems, and puts forward the main purpose of the design and content. ChapterⅡ- related technology research, it describes the use of embedded systems, ARM processor and S3C2440A. ChapterⅢ- the overall design about the pacify system of the trapped elevators, the main components of the system, the overall program, function description, and the overall design work process. ChapterⅣ- to achieve the hardware of the pacify system of the trapped elevators, focuses on the elevator operation monitoring terminal hardware and circuit design. ChapterⅤ- to design the software of the pacify system of the trapped elevators, focuses on embedded system design and interface application kernel driver. ChapterⅥ- summary, it summaries the function and achievement of the pacify system of the trapped elevators, also collects more data available and provides the reliable information for the product design.Therefore using the ARM and GSM/GPRS technologies developed a PC can the remote monitoring and control of elevator trapped ladder intelligent security system for the elevator, discover and analysis, and identify the fault belongs to the elevator, as happened trapped ladder fault fault trapped ladder through GSM/GPRS technologies timely and regulators and maintenance personnel, promptly rescue, while in the process of the elevator's being soothed and personnel that some elevators. Using the independent testing, the elevator control system is separated, won't destroy the elevator control system, the use of safe, can apply to all kinds of elevator. Using the wireless communication of on-line can greatly reduce each elevator communication costs, easy to large scope.
