In order to improve the reliability of the dangerous load identification of the belt conveyor, it is necessary to ensure the redundancy and robustness of the information collection. Therefore, different types of multi-sensors, such as tension sensors, oil pressure transmitters, etc., are used in the dangerous load warning system. Vibration sensors, shaft encoders, etc. will be used. Under the premise that the belt conveyor meets the system's effectiveness and reliability, the cost of the multi-sensor system should be reduced as much as possible, which is conducive to subsequent promotion.
For the information fusion and the next chapter of signal processing research, the belt conveyor needs to collect load signals under various working conditions through various sensors. However, this part of the pilot research at the coal mine production site will greatly affect the safety and production progress of the conveyor operation of the belt conveyor, so it is necessary to build a process that can not only achieve loading, running, unloading, but also simulate Test equipment for faults such as loading, unloading, loose ropes, and cans, and the load under different working conditions can be recorded by multi-sensor and signal acquisition system.
The motor drives the reel through the reducer, and the lifting and lowering of the conveying container are realized in the forward and reverse directions respectively. The conveying container of the belt conveyor has an opening and closing device, which can be loaded and unloaded, and can simulate the loading and unloading failure; the square tube guiding device and the derrick are bolted together, and the defects such as misalignment and protrusion can be artificially formed to form the slack rope. Card case. Under various working conditions, the signals of the belt conveyor convert the signals such as tension and oil pressure into electric quantity, convert, amplify, filter and collect through the acquisition system, and then transmit the digital signal to the computer to carry out the dynamically changing conveying load. Record, display, and analyze.
In order to improve the reliability of the dangerous load diagnosis of the belt conveyor, multiple or multiple types of sensors are needed for information collection. Whether the redundancy and complementarity of information can be transformed into the reliability and robustness of the system, it is also necessary to select appropriate algorithms for information fusion, increase credibility and reduce ambiguity. For overloading of the belt conveyor, if the overload is not large, an alarm is issued to alert the operation and maintenance personnel. However, if the overload is large, the belt conveyor safety circuit must be disconnected to avoid an accident. The same is true for other dangerous load modes.
