The design model of smart box door access system is a kind of lock. When it is opened, a series of numbers or symbols are used. The text password lock can be divided into: mechanical password lock, digital password lock, etc. The password of the password lock is usually only an arrangement rather than a real combination. Some password locks only use one turntable to rotate several discs or cams in the lock; Some password locks rotate a group of dials engraved with numbers to directly drive the internal machinery of the lock. It does not contain parameters, but can be edited. It can be opened with SOLIDWORKS 2010, and draw good learning materials

be based on PLC Design of planer electric control system based on dsp
The traditional planer control system has poor reliability, difficult maintenance, low processing quality and production efficiency. With the continuous development of PLC technology, it is a simple and feasible method to design the electrical control system with PLC. The electrical control system of gantry planer designed with PLC introduced in this paper not only meets the required control functions, but also has the characteristics of simple structure, stable operation and easy maintenance on the premise of saving money. Especially, the hardware is simple and reliable, the software is rich and flexible, and the operation effect is good. The impact free commutation of the worktable is realized under the condition that the programmable controller detects the speed zero crossing. With the precision potentiometer as the speed setting element, the main motor speed can be adjusted manually and accurately in real time, which fundamentally overcomes a series of shortcomings of the gantry planer, such as large reversing impact, low work efficiency, and large power consumption. The system outputs the real-time speed of the main motor and the armature current with digital display, which is accurate and intuitive. The way and method of using PLC to design the electric control system of gantry planer provides a new idea for improving the design of machine tools, and has certain significance for promoting the technological progress of industrial enterprises. Key words: programmable logic controller; Gantry planer; Control system; DC speed regulation; Planer motion control
