可编程控制器在南通狼山空中缆车中的应用

The application of programmable logic controller in air cable car for Langshan in Nantong

摘要:

介绍了可编程控制器（ＰＬＣ）在南通狼山空中缆车中的应用及该系统的软、硬件结构。系统采用日本ＯＭＲＯＮ公司生产的Ｃ６０Ｐ－ＣＤＲ－Ａ主机、Ｃ６０Ｐ－ＥＤＲ－Ａ扩展机和少量的中间继电器来代替传统的继电－接触器控制系统，各接触器都有辅助触点反馈回ＰＬＣ，采用行程显示技术以实时显示吊厢的实际位置，出进站时的加减速均采用软硬件双重控制，用梯形图编制开／停车逻辑控制、速度给定处理、行程显示、各种紧停及报警处理程序。实践证明，该系统具有有效的故障自诊断能力，灵活的控制方式，检修、维护更简便，可靠性大大提高。

Abstract:

This paper introduces an application of progammable logic controller (PLC) in air cable car for Langshan in Nantong and describes its software and hardware configuration structure. The main machine C60P CDR A, expanding machine C60 EDR A made in Japan and a few relays instead of a lot of contacters to achieve technological specfication process. An auxiliary contact of each contacter feedbacks to the input of PLC. The actual distance of travel of car is displayed by using PLC technology. The deceleration and acceleration as the car arriving at or departing from the station are dual controlled by software or hardware. The procedures about start up and stopping, given value of speed, alarm and display are programmed in ladder diagram language. Facts proved that the system has higher reliability, effective self diagnostic ability, flexible controlling mode. It is very simply and convenient to examine and repair.
