"基于80C196KC单片机的胶带输送机智能软启动器设计与应用研究"。

ue to the development of the national economy, the mechanization and automation level of coal production in China has been continuously improving, leading to the increasing use of long-distance, high-volume, high-power belt conveyors. In particular, they are widely used in industrial sectors such as coal mines. The domestic belt conveyor is also developing towards long-distance, high belt speed, large inclination angle, and high power. The soft starting problem of high-power belt conveyors has become increasingly prominent, and has become a bottleneck for the development of belt conveyors. Currently, some soft starting technologies have been adopted domestically, such as hydraulic coupling technology and constant speed technology (CST), but each has its own drawbacks. This paper, based on the starting characteristics of belt conveyors, combined with the high-speed processing capability of the 16-bit single-chip microcomputer Intel 80C196KC, researched and designed an intelligent soft starter for belt conveyors based on the phase-controlled voltage regulation theory of thyristors, with the single-chip microcomputer Intel 80C196KC as the control core and the thyristor as the main control device. It has achieved soft start, soft stop, and various protection functions for belt conveyors. The significance of researching belt conveyor soft starters lies not only in ensuring smooth start-up and braking, but also in reducing the cost of belt conveyors and ensuring safety in production.
