该梯是中国建筑科学研究院建筑机械化研究所继湖南益阳、湖北电梯厂之后,与国营中原电梯厂联合研制的交流调速电梯的第三个新产品。其主要特点是采用8031单片机来对电梯进行实时控制,同时保留了原主要技术指标以及起、制动,运行各段实施的方法。该系统原理图见图1。图中GM为光电脉冲转换部分,输出脉冲序列CP既可表示位置,也可处理成电机转速。μP为微机系统,采用以8031单片机为核心,配置少量的外围器件组
The ladder is China Building Research Institute of Building Mechanization, following the Hunan Yiyang, Hubei Elevator Factory, with the State-owned elevator factory jointly developed the third exchange speed elevator products. Its main feature is the use of 8031 microcontroller to real-time control of the elevator, while retaining the original main technical indicators and starting, braking, running the implementation of the various methods. The system schematic shown in Figure 1. In the figure, GM is the photoelectric pulse conversion part, the output pulse sequence CP can represent the position, and can also be processed into the motor speed. μP for the computer system, using 8031 microcontroller as the core, configure a small amount of peripheral device group
