Abstract: Longitudinal breakages of conveyor belts in modern coal mines can lead to significant economic costs due to downtime of mine equipment and expensive repairs. Currently, many longitudinal breakage detection devices on a conveyor belt (LBDD) are known. One of the promising directions for solving the problem of detecting a longitudinal breakage can be considered the transmission of energy in the form of electromagnetic fields along the cross-section of the conveyor belt. The disadvantages of this solution include difficulties in reading information by the receiver due to a large number of interferences in the loop built into the conveyor belt in mine conditions. In order to improve the reliability of the LBDD operation, the Departments of Mining Machines and Complexes and Electric Drive and Automation of the Kuzbass State Technical University named after T.F. Gorbachev (KuzSTU) have developed a device in which the transmitter and power source are located in the conveyor belt, several variants of the LBDD structural diagrams have been proposed, and the requirements for the transmitter and receiver have been determined. The conveyor belt longitudinal break sensor includes a transmitter, the parameters of which are determined at the design stage. The receiver is part of the logical block located on the conveyor frame. One of the promising schemes of conveyor belt break sensors can be considered a scheme made using a Wiegand sensor, which, with sufficient magnetic induction from a magnet located on the conveyor frame, forms a voltage pulse at the output for short-term power supply and operation of the transmitter circuit. The purpose of the work is to study the possibility of using Wiegand sensors in the LBDD for minimizing the impact of electromagnetic interference, ensuring high sensitivity and reliability of the system when detecting a break in the conveyor belt, low probability of false alarm, low cost and energy consumption.
