More Information
Summary:The invention discloses a cage personnel number and limb extension monitoring device and method. A microcontroller (5) collects and processes the light intensity values of first LED lamps (1) on the safety helmets of miners through a light signal sensor and the light intensity value of a second LED lamp (3) at the top of a cage door, and transmits processed electric signals to an external server (6). The external server processes the received electric signals to obtain light frequency information, namely light frequency values and a light frequency power value. A worker in a monitoring centerobtains the number of the miners in the cage according to the number of the obtained different light frequency values, and judges whether the limbs of the miners stretch outwards or not according to the change of the light frequency power value. According to the invention, the number of people and limb extension can be monitored in real time by using a visible light communication technology, the technical configuration is
