Human body induction and risk detection system and method for construction safety

The invention relates to a human body induction and risk detection system and method for construction safety, and belongs to the technical field of construction safety guarantee. The system comprisesa human body induction device and a risk monitoring device. The human body sensing device comprises a heat-sensitive sensor for sensing a heat signal similar to the temperature of a human body and a position sensor capable of setting a detection distance according to a dangerous range of a construction site. The risk monitoring device comprises a current sensor used for detecting the working stateof the equipment, a stress sensor used for detecting the load condition of the equipment, a circuit breaker used for terminating the action of the equipment before danger occurs, and an alarm used for sending alarm information to a person threatened by safety. By means of the human body induction device, human bodies and materials can be distinguished, and therefore the problem that moving objects such as the materials or
