Research And Development Of Amlu2000 Automatic Torque Limiter

The moment limiter for crane is one important overload protector, it is very essential for crane to work safely. On the basis of studying of the moment limiter at home and abroad, this paper develops an advanced moment limiter named AMLU2000, which takes advantage of the progress of technology in the field such as electronic, computer, sensing and testing. With function related is all ready, AMLU2000 not only can run reliably, but also provides convenient operational mode. It possesses the general function such as detecting, controlling, real-time displaying and so on, as well as the voice interface for reporting parameter and prompting work state, the module of black-box function for recording data of overload state, which realize the higher intelligence. This paper applies itself to perfect the function of the moment limiter and improve the advancement and credibility. To simplify the system designing, this paper adopt serial device with the way of modeling designing. 0n the basis of over-all designing of the moment limiter, this paper develops the whole limiter system, designing entirely circuit and compiling the controlling program with C-5 1 language. In addition, this paper adopts a series of hardware and software protecting measures to enhance the ability of anti-jamming. The final result of the experiment indicates that the whole system works accurately and credibility realizing the presumed object.
