| Abstract: | Elevators controlled by relay have high fault ratio and low dependability which have affected the security of elevators. PLC is a new industry controller, has excellent performance and becomes the first project of elevator alteration . Elevators become a fan of building stakeout and control system with building automation developing. The paper takes an elevator in SHENZHEN as an example, introduces the application of MIISUB-ISHI Programmable Logical Controller and Direct Digital Controller in elevator stakeout and control system, the system achieves good effect in practical application. |
