    "patent_abstract": "A brake system for a conveyor system. The brake system includes a brake, a distance detection device and a controller. The brake includes a brake arm and a brake lining connected to the brake arm. The distance detection device is arranged on the brake for detecting a first distance and a second distance between the brake arm and a brake drum, where the first distance is a distance between the brake arm and the brake drum when the brake is in an open state, and the second distance is a distance between the brake arm and the brake drum when the brake is in a closed state. The controller is used for determining a brake performance of the brake based on a difference between the first distance and the second distance detected sequentially, and for generating and sending warning signals when the difference is not within a preset range.",
    "precision_class": "structural",
    "invention_explanation": "A brake with a sensor measures the gap between its arm and drum when open and closed, allowing a controller to identify brake operation or wear.",
