Material conveyor belt - tear monitoring

The system uses advanced technical means to realize real-time monitoring of the belt status of the transport aircraft 24/7. Once abnormal conditions such as belt tearing are found, an alarm will be triggered immediately, and the signal will be synchronized to the transport aircraft to stop running, thus avoiding greater losses

Running state data collection
Adopt 3D lidar and line scanning laser + vision equipment for real-time monitoring, and accurately collect belt operation data
Data analytics
According to the data collected from lidar and line-scanning laser, data analytics and feature extraction are carried out on the running states of belt movement, no-load, offset, overflow, tear, blockage, and stacking
decision-making basis
Based on the extracted features, it is compared and analyzed with the preset normal operation model and fault characteristic model. With the help of machine learning and artificial intelligence algorithms, it is possible to determine whether the current operating state of the belt conveyor is normal. Once abnormal conditions are found, the type, location and severity of the fault can be located in a timely and accurate manner, and then provide a basis for subsequent alarm prompts or automated intervention decisions.

How to solve the challenges encountered
Mining industry
During the mining process, the conveying belt needs to transport a large amount of ore and other materials. These materials have high hardness and sharp edges, which can easily cause scratches and tears to the belt. Through the belt tear detection system, the belt tear can be detected in time to avoid ore leakage and ensure the smooth progress of production. For example, in the conveying belt system of an open-pit coal mine, a belt tear detection device is installed, which effectively reduces the number of production interruptions caused by belt tears.
Port loading and unloading transportation
The port needs to handle the loading, unloading and transportation of various goods. During the long-term operation of the conveyor belt, it may be torn due to the impact and friction of the goods. The belt tear detection system can monitor the running status of the belt in real time. Once a tear is found, it will be alerted in time to reduce the loss of goods and equipment damage.
Power industry
The coal conveying belt of a power plant is an important equipment for fuel transportation, and the reliability of the belt directly affects the stability of power generation. The belt tear detection system can conduct all-round monitoring of the coal conveying belt, detect potential tear hazards in time, and ensure the normal power generation of the power plant. For example, in the coal conveying system of a thermal power plant, the installation of belt tear detection equipment provides a reliable guarantee for power production.
Reduce material loss
It can detect belt tears in time to avoid material leakage from the tear and reduce material waste and loss. For example, in the chemical industry, the transported materials often have high value. Through the belt tear detection system, the cost of material loss can be effectively reduced.
Reduce the risk of equipment damage
When the belt tear is not detected in time, it may lead to further damage to the belt and even cause other equipment failures. The belt tear detection system can provide early warning, allowing the staff to take timely measures to reduce the risk of equipment damage and prolong the service life of the equipment. For example, in the raw material conveying belt of the cement plant, the belt tear is detected in time to avoid the damage of the crusher and other equipment caused by the belt failure.
Improve production safety
Prevent material leakage from posing safety threats to workers and ensure the safety environment of the production site. For example, in the conveying belt system in the mine, the application of the belt tear detection system effectively avoids safety accidents caused by material leakage.
Complex Environmental Interference
In some industrial sites, there are complex environments such as high temperature, high humidity, dust, mud, and electromagnetic interference, which may affect the normal operation of sensors and monitoring equipment, resulting in inaccurate test results. For example, in the high-temperature material conveying belt scene of a steel plant, high temperature may degrade the performance of the sensor and affect the accuracy of belt tear detection.
Variety of belt materials and operating conditions
The belt materials and operating conditions used in different industries vary, such as rubber belts, nylon belts, etc., as well as different conveying speeds and loads, which increase the versatility and adaptability of the detection algorithm. For example, in the food industry, the food-grade belts used are very different from industrial belts in terms of material and operating requirements, and the detection algorithm needs to be optimized specifically.
Adopt anti-jamming technology
For complex environmental disturbances, sensors and monitoring equipment with resistance to high temperature, high humidity, dust, and electromagnetic interference are selected, and shielding and filtering measures are taken to reduce the impact of environmental factors on the detection results. For example, in high-temperature environments, use high-temperature fiber optic sensors and insulate the sensors; in environments with strong electromagnetic interference, use shielded cables and anti-interference monitoring equipment.
optimization detection algorithm
Through a large number of experiments and data collection, the detection algorithm is trained and optimized for different belt materials and working conditions to improve the versatility and adaptability of the algorithm. For example, the deep learning algorithm is used to learn and train belt tear samples under different materials and working conditions, so that the algorithm can accurately identify belt tears in various situations. At the same time, combined with the adaptive algorithm, the detection parameters are automatically adjusted according to the real-time operating parameters of the belt to improve the accuracy of detection.
