| Abstract: | This paper describes an automatic landing system to control construction hoist cage. It uses programmable controller FXZN-40MR as a major control unit. The counting frequency of the high speed counter is up to 5 KHz. The counting value can keep valid during electricity cutoff. Landing accuracy is in high level. High speed programming can suit to the change of environment. |
