Engineer safety black box

As China's title of "Infrastructure Maniac" becomes widely known, more and more workers are engaged in dangerous jobs, such as high altitude, underground, tunnels, and engineering vehicles. In order to ensure the safety of these construction workers and ensure timely rescue in the event of an accident, I designed this safety black box for engineering personnel. This equipment can collect the heart rate of construction workers, the temperature and humidity of the surrounding environment, identify the state of movement, and determine whether a fall or collision accident has occurred. It is transmitted to the remote monitoring center through the network. Once the monitoring personnel find an abnormality, they can immediately organize rescue.
