The embodiment of the invention provides a telescopic sidewalk alarm based on the Internet of Things. When the alarm controller receives a current red light signal sent by the traffic light alarm, thealarm controller controls the first working head shell and the second working head shell to rise. At the moment, the alarm controller controls the infrared emission device to be started, the alarm works and gives out an alarm signal. When the alarm controller receives a current green light signal sent by the traffic light controller, the alarm controller controls the first working head shell andthe second working head shell to retract. Upon completion of a retraction procedure, the infrared emitter is positioned in the first fixed shell, the infrared receiving device is located in the secondfixing shell, the first fixing shell and the second fixing shell play a role in protecting the infrared transmitter and the infrared receiver, pedestrians are prevented from making direct contact with the infrared transmitter and the infrared receiver, and therefore the damage rate of the infrared transmitter and the infrared receiver is reduced.
本发明实施例提供的一种基于物联网的伸缩式人行道报警器,当报警控制器接收到红绿灯报警器发送的当前为红灯的信号时,报警控制器分别控制第一工作头外壳与第二工作头外壳升起,此时报警控制器控制红外发射装置开启,报警器工作,发出报警信号,当报警控制器接收到红绿灯控制器发送的当前绿灯信号时,报警控制器控制第一工作头外壳与第二工作头外壳缩回,当缩回过程完成后,红外发射器处于第一固定外壳内,红外接收装置位于第二固定外壳内,第一固定外壳与第二固定外壳对上述红外发射器和红外接收器起到保护作用,避免行人直接接触到上述红外发射器和红外接收器,以此来减小红外发射器和红外接收器的损坏率。
