Abstract

This invention discloses a factory equipment operation status monitoring system and method based on graphene photoelectric sensing, relating to the field of suspended ball monitoring technology in industrial equipment. It is suitable for non-visual position detection of suspended balls inside glass containers in dusty environments. It can monitor the position of suspended balls inside glass pipes on hundreds of pieces of equipment in a factory to determine whether the equipment is operating normally. This invention uses a graphene photoelectric sensor installed on the outside of the glass pipe, detecting the suspension position of the ball through changes in the graphene photocurrent signal, achieving non-contact, non-visual monitoring. The system includes a graphene photoelectric sensor module, a laser module, and a data transmission and alarm module. It can monitor multiple devices in real time, supports wireless networking, and is suitable for industrial environments with severe dust pollution. This overcomes the shortcomings of traditional visual monitoring in dusty environments, achieving reliable position detection of suspended balls inside glass pipes, and is cost-effective and easy to operate and install.
