摘　　要：针对目前各种电动轮椅仅具备制动功能,缺少对乘坐者的安全保障这一问题,因此,设计了一种针对电动轮椅安全的监控系统。该系统以意法半导体的STM32为主控芯片,以轮椅位置、座椅压感、电机运行状态及乘坐者体温等一系列指标作为监测对象,对这些信息进行采集并分析做出相应的响应信息,将响应信息通过无线传输模块,采取MQTT协议上传至云端服务器进而传送至手机端,通过手机端进行对轮椅安全状况的实时监测和对轮椅的远程控制。对硬件进行连接并进行大量实验后,该系统即时性高,操作简便,能够对轮椅出现的各种情况进行实时监测并进行远程控制,具有较好的应用前景。At Aiming at the problem that all kinds of electric wheelchairs only have braking function and lack of safety protection for passengers, this paper designs a monitoring system for wheelchair safety. The system takes STM32 of STM semiconductor as the main control chip, and takes a series of indicators such as wheelchair position, seat pressure, motor running status and passenger′s body temperature as the monitoring objects. These information are collected and analyzed to make corresponding response information. The response information is uploaded to the cloud server by mqtt protocol through the wireless transmission module, and then transmitted to the mobile phone It can monitor the safety of wheelchair and control the wheelchair remotely. After connecting the hardware and doing a lot of experiments, the system has the advantages of high instantaneity, simple operation, real-time monitoring and remote control of various situations of wheelchair, and has a good application prospect.
