摘要
针对高速电梯控制系统不断增加的功能需求以及电梯智能化、安全性、可靠性等方面不断提高的要求,用ARM构建电梯主控制器硬件平台并完成了BootLoader及uCLinux操作系统的移植;编写了CAN总线等相关驱动程序;设计了高速电梯的跑层逻辑控制算法以及基于多目标规划和支持向量机的电梯群控算法;采用SQLite实时数据库快速实现电梯运行参数的存储与读取;同时采用CPLD和AVR单片机设计主、辅两套高速计数电路,保证了电梯在高速运行状态下的稳定性与可靠性。在电梯模拟控制台上的实际测试验证了该电梯主控制器设计的合理性与可靠性。
In order to meet the increasing function needs of express elevator control system and the growing improved requirements of the elevator in intelligence,security and reliability,in this paper the ARM chip is used for the construction of hardware platform of elevator＇s main controller.Bootloader and uCLinux operating system are ported on this platform,and corresponding drivers such as CAN-bus are designed as well.Express elevator＇s operation logical control algorithm and elevator group control algorithm based on multi-objective programming and support vector machine are designed.SQLite real-time database is introduced into this system to implement rapid store and access of elevator operation parameters.CPLD-based main high speed counter is designed while the auxiliary one is implemented with AVR MCU,this redundant architecture of high speed counter guarantees the stability and reliability of elevator system.Practical tests carried out on elevator simulation platform verify the correctness and reliability of the design of elevator＇s main controller.
