Sensing technology detection method, system and device of safety grating and medium

The invention provides a sensing technology detection method, system and device of a safety grating and a medium. Acquiring first working information of the safety grating; determining a first working state of mechanical equipment related to the safety grating; determining a first safety range based on the first working state; obtaining the working position of a first type of working personnel and the interaction information among the first type of working personnel, the safety grating and the mechanical equipment; and determining a first safety value based on the working position, the first safety range and the interaction information. Infrared rays or laser beams and the like are adopted to detect whether an object enters or passes through an obstacle, so that extremely high accuracy can be realized; once an object is detected to enter or pass through an obstacle, a signal is immediately sent to the control system to trigger emergency shutdown, so that accidents are avoided; and effective physical isolation
