Roller kiln rod breakage alarm method and system based on visual anti-shake judgment

The invention relates to the technical field of monitoring and alarming, in particular to a roller kiln rod breakage alarming method and system based on visual anti-shake judgment. According to the scheme, ultrasonic sensors are arranged on a kiln body and a roller; the position of a broken rod roller is collected on line through a laser shielding piece and a laser range finder; the actual positions of all the broken bars and the positions of rollers of the broken bars are automatically extracted and stored in historical shaking data; calculating a real-time jitter error on line according to the historical jitter data; when the real-time jitter error meets the jitter margin, determining how to set the current broken rod position; and when the real-time jitter error is less than the jitter margin, determining how to set the current broken rod position. According to the scheme, in the laser judgment process, the vibration process is judged by arranging an ultrasonic sensor and visual perception equipment on a r
