The invention relates to the technical field of elevator fault alarm, in particular to an automatic alarm system for people trapped in an elevator based on the Internet of Things. The automatic alarm system for people trapped in the elevator based on the Internet of Things comprises a shell, a monitoring component used for monitoring the safety of the elevator is installed in an installation cavity formed in the shell, and a thermal imager used for detecting thermal imaging of human bodies in an elevator car and a temperature sensor used for detecting the temperature in the elevator car are embedded in the shell; and the protection part is located on the inner top wall of the elevator, and fire extinguishing treatment is conducted in the elevator car through the protection part. According to the elevator trapped person automatic alarm system based on the Internet of Things, the monitoring component is matched with the thermal imager, after the potential difference value and the thermal imager transmit electric signals to the controller at the same time, the controller transmits an alarm signal to the elevator monitoring room, trapped persons can be quickly rescued, and the safety of the elevator is improved. And the falling speed of the elevator can be provided for subsequent safety investigation by utilizing the recorded potential difference value.
本发明涉及电梯故障报警技术领域,尤其涉及一种基于物联网的电梯困人自动报警系统。所述基于物联网的电梯困人自动报警系统包括壳体,所述壳体内设的安装腔中安装有用于监测电梯安全性的监测部件,所述壳体上嵌合有用于检测电梯厢内人体热成像的热成像仪以及用于检测电梯厢内温度的温度传感器;防护部件,位于电梯的内顶壁上,通过所述防护部件对电梯厢内进行灭火处理。本发明提供的基于物联网的电梯困人自动报警系统通过监测部件配合热成像仪,使得电势差值和热成像仪同时向控制器传送电信号后,由控制器向电梯监控室内传送报警信号,使其可以快速解救被围困人员,而利用记录的电势差值可以为后续安全调查提供电梯下坠的速率。
