The invention discloses a monitoring system and method for abnormal state of belt conveyor rollers based on speed detection. The system uses a video acquisition device to mark on the rollers of the belt conveyor to collect video images of the rollers when they rotate. , process the collected images, identify the marks made, and calculate the trajectory of the mark points in real time. By calculating the number of times the marks appear per unit time, calculate the rotational speed of the idler roller, and according to the rotational speed of the idler roller and the conveyor belt conveying The ratio between the speeds determines whether the idler is in an abnormal state, and displays the real-time running data of the rotating speed of the idler, the running speed of the conveyor belt, and whether the idler is in an abnormal state. The invention applies the computer image recognition technology to realize the monitoring of the running state of the idler roller of the belt conveyor based on abnormal speed detection, which is of great significance for ensuring the safe operation of the belt conveyor. The invention has good interactivity and operability, strong practicability and high value of popularization and application.
Description
technical field [0001] The invention relates to a speed detection-based monitoring system and method for the abnormal state of idler rollers of a belt conveyor, belonging to the technical field of mechanical equipment detection. Background technique [0002] Belt conveyors are commonly used transportation equipment in factories and mines. However, in the continuous operation of high-speed, large-capacity, and long-distance transportation, if the idler rollers slip or lock up, it is easy to cause serious accidents such as conveyor belt breakage, which will cause heavy losses to the enterprise. Therefore, it is very important to detect the working state of the idler. [0003] However, many existing monitoring methods and devices for monitoring the abnormal state of belt conveyor rollers have problems such as complex structure, inconvenient operation, and high false alarm rate; poor security issues. Therefore, how to provide a detection method and device that is simple in st...
