绪言微处理机用于电梯控制是从自动群监控制系统用于控制多台电梯的运行开始的。近年来,微处理机的应用已扩展到成批生产的标准化电梯的单台电梯运行控制了。同时,对电梯的要求也日益增多了,要它们在建筑物内部节约能源,提高输送设备的效率。这种趋向在使用直流电梯的大型办公楼和高层旅店内最为显著。日立公司为此研制出全固态电梯系统来适
INTRODUCTION Microprocessors for elevator control start from the automatic group supervisory system used to control the operation of multiple elevators. In recent years, the application of microprocessors has been extended to a single elevator operation control of a batch of standardized elevators. At the same time, the requirements for elevators are also increasing. They are required to save energy in buildings and improve the efficiency of transportation equipment. This trend is most noticeable in large office buildings and high-rise hotels that use DC elevators. Hitachi has developed an all-solid-state elevator system for this purpose
