基于ARM的电梯超载控制系统设计

A Design of the Control System for Overloaded Elevator Based on ARM

为实现电梯轿厢的安全运行,避免电梯超载判定单一依靠重力传感器所引发的安全事故,研究设计了基于ARM处理器实现的轿厢人数检测结合重力传感器的双重判定控制系统。系统以ARM Cortex A8处理器为主控制器,视频采集电路模块、语音报警电路模块、Linux2.6.32内核及智能识别算法等软硬件构成,实现对电梯轿厢人数检测、双重判定、语音报警和电梯运行等控制。系统通过仿真调试,运行可靠、控制准确,具有一定的推广价值。

For safe operation of the elevator car and avoidance of safety accidents caused by elevator overloading with sole detection of the gravity sensor,a control system with dual sensors is developed and designed based on ARM that could perform both detections of the number of persons in the car and the gravity. This system adopts ARM Cortex A8 processor as the main control and is integrated with a series of hardware and software including video capture circuit module,voice alarm circuit module,Linux2. 6. 32 kernel and intelligent recognition algorithm etc. to achieve the detection of the number of persons in the elevator car,double determination,voice alarm and elevator control. Through simulation debugging it proves that the system is reliable in operation and accurate in control with certain promotional value.
