Design of elevator condition evaluating device based on STM32 and Android

文中针对目前大部分电梯检测方案存在的不易操作的问题,提出了一种便捷的基于STM32和安卓的电梯状态检测装置设计方案,并完成系统的软硬件设计。系统主要由速度、加速度、温湿度、光强检测模块及智能手机组成。各采集模块完成数据采集与基本处理后,将数据通过蓝牙传给手机软件。手机软件分析处理测量数据,按照国标阈值对测量值进行初步分析,再使用层次分析法得到对电梯的总体评分。使用该系统对学校电梯了进行检测,评分结果与各电梯实际情况相符合,实验结果表明该系统可以较为准确地评估电梯状态。

In this paper, we design an elevator condition evaluating device based on STM32 and Android in order to make elevator condition evaluation more convenient. We complete the design of hardware and software in this system, which consist of speed, acceleration, temperature, humidity and light intensity detection module as well as a smartphone. Sensors collect the corresponding data, and then it was transmitted to a smartphone using Bluetooth. After that, the application in smartphone analyses those measured data according to the national standard of China. And the score of the elevator condition was calculated using Analytic Hierarchy Process. During the experiment, we tested elevators in our school. The results were in accordance with the ground truth, which shows that this system can assess the condition of the elevator accurately.
