【摘要】 起重机力矩限制器是装备在起重机上的重要超载保护装置，它为起重机的安全工作提供保障。本文在对国内外现有的力矩限制器进行了深入详尽的对比和分析基础上，借鉴和传承了它们的成功经验，提出了系统主控单元与显示单元相互分离的设计思想，进行了新型起重机力矩限制器的研制。独特的系统解决方案具有通用性好、多功能、高精度、低建设维护成本以及系统可扩展性强等优点。 本文所述起重机力矩限制器的主控单元是以单片机W77E58为核心部件，对从各传感器采集到的数据进行计算、判断处理，做出各种控制动作；显示单元选用了W78E58作为控制器，并采用了人机交互方便，显示信息量大的点阵液晶显示面板，可动态显示起重机的工况参数。两单元间的数据传输依靠自主开发的通讯协议来保证。 经过实验室实际调试，运行结果表明：系统整体设计合理、性能可靠，实现了预期的设计目标。更多还原

【Abstract】 Crane moment limiter that is equipped on the crane is an important overload protective device. It provides safeguard for the safety work of crane. This paper is based on the efficient experience learnt through the comparison and analysis of the present domestic and foreign moment limiter. In this paper, the author proposes the idea of separating the main control unit of system and the display unit, which can enhance generation and function, greatly reduce building and maintenance costs, increase the precision of control and boost up expansibility of system.MCU W77E58 is used as a core component in the main control unit of system. It samples signals from the sensors, calculates, judges and executes the corresponding control action. In the display unit, the author chooses W78E58 as the controller. Liquid Crystal Display, which can provide both interaction between people and machines and a large amount of information, is applied, so that the parameters of the working conditions of crane can be displayed dynamically. Data transmission between the main control unit and the display one is supported by the communication protocol that is developed by the author.The adjusting and running of the system indicates that the whole design is feasible and reliable, and the presumed functions have been conducted successfully.更多还原
