带式输送机能否安全可靠的运行,不仅与它本身的机械结构与设计的可靠性有关,而且与其控制保护系统的安善及可靠性有关。而输送带的速度与加速度则是实现各种控制与保护的主要参量。本文提出了一种线路——简单、可靠性高的速度与加速度检测电路及设计方法。
The safe and reliable operation of the belt conveyor depends not only on the reliability of its own mechanical structure and design but also on the safety and reliability of its control system. The conveyor belt speed and acceleration is to achieve a variety of control and protection of the main parameters. This paper presents a circuit - a simple, high reliability speed and acceleration detection circuit and design method.
