Hay stackers are the key equipments, Performanc

2、e of the stacker playsan important role. Design and Development of a higher degree of automationStacker Control System become Warehouse trend of development, Thereforerelated research has important theory and application value. This paper introducesapplication and performance of automated High-rise

3、Warehouse basing onapplication and development requirement of modern logistics techniques. And putsemphasis on the researching of control techniques in automated High-riseWarehouse stacker combining modern science and techniques. This paperelaborated on the design of the system of control, as well a

4、s the implementation ofthe systems hardware and the design of the software.Based on the parameter related to the automated storage, this paper presentedthe hardware system of stacker electrical control. Speed of the stacker was thebasic. In order to improve the performance of the stacker, the system

5、 adopts thespeed, position, double feedback control. The horizontal recognize addresses ofsystem using laser rangefinder sensor positioning, and vertical recognition usingphotoelectric switches and address piece combination addressing. Speed-adjustedsystem by S7-226PLC and its extension module EM235
