4月18日,由我院电子系和湖南益阳电梯总厂合作研制的“TKJ1000/0. 75-JXW 微机控制双速自动化乘客电梯”由湖南省科委主持通过省级鉴定,微机控制自动化电梯的研制成功,把微机控制与拖动主回路相结合作为一个完整产品,填补了国内空白。随着微电脑技术的迅速发展,电梯的控制方式采用微型计算机国外已很普遍,但目前国内生产的电梯其控制系统均采用50年代的继电集选逻辑控制,它的主要缺点是不能适应不同的运载要求、功能单一、可靠性差,而且楼层数增加时要求增加大量的作为逻辑控制的继电器,从而使成本增加、体积增大,安装和维修困难。
On April 18, “TKJ1000 / 0. 75-JXW microcomputer-controlled two-speed automated passenger elevator” developed by the Department of Electronics of our college and Hunan Yiyang Elevator Factory was presided over by Provincial Science and Technology Commission and passed provincial appraisal. The microcomputer-controlled automatic elevator The success of the development, the computer control and drag the main loop as a complete product, to fill the gaps. With the rapid development of microcomputer technology, the control mode of elevator has been widely used in microcomputer abroad. However, the control systems of elevators in China are all controlled by the relay set-selection logic of the 1950s. Its main disadvantage is that it can not adapt to different Carrying requirements, single function, poor reliability, and increase the number of floors require a large number of logic control as a relay, so that the cost increases, the volume increases, installation and maintenance difficulties.
