The invention discloses a detection system for remotely monitoring people in an elevator. The detection system comprises a signal acquisition mechanism, an elevator Internet of Things terminal and an elevator Internet of Things platform, the signal acquisition mechanism comprises a plurality of voice and infrared sensors and a plurality of weighing sensors, and the voice and infrared sensors are installed at the four corners of a ceiling of an elevator car so as to detect voice signals and infrared signals in the car; the weighing sensors are installed at the four corners of the car bottom so as to detect load signals in the elevator; and the elevator internet-of-things terminal obtains the voice signals, infrared signals and load signals and transmits the signals to the elevator internet-of-things platform, and the elevator internet-of-things platform judges whether a person exists in the elevator or not according to the three signals so as to generate a person-in determining signal. Whether a person exists or not is judged through the voice and infrared sensors at the four corners of the ceiling and the weighing sensors at the four corners of the car bottom, the detection modes are diversified, and the detection accuracy is high. The invention further discloses a corresponding monitoring system for remotely monitoring people trapped in the elevator.
本发明公开了一种用于远程监测电梯有人的检测系统,检测系统包括信号采集机构、电梯物联网终端和电梯物联网平台,信号采集机构包括语音与红外传感器、称重传感器,语音与红外传感器有多个并安装于电梯轿厢吊顶四个角以检测轿厢内语音信号和红外信号;称重传感器有多个并安装于轿底四个角以检测电梯内载重信号;电梯物联网终端获取语音信号、红外信号和载重信号并将其输送至电梯物联网平台,电梯物联网平台依据三种信号判断电梯是否有人以生成有人确定信号。本发明通过吊顶四个角的语音与红外传感器、轿底四个角的称重传感器判断是否有人,检测方式多样,检测准确性高。本发明还公开了对应的远程监测电梯困人的监控系统。
