Abstract
This paper mainly introduces the subject background, the research status at home and abroad, the research purpose and significance, the basic concept, the working principle, the development course and the current situation of PLC (Programmable Logic Controller).In the industrial production of the No.Smart cabinets are specifically designed specifically for the actual situation of the increasing use of household items.This paper briefly introduces the use, development and operation mode of the intelligent storage cabinet, introduces the characteristics and uses of the configuration software, and describes the overall framework and hardware structure of the control system in detail.
This paper uses PLC technology to reasonably design the intelligent storage cabinet control system, mainly using Mitsubishi FX2N series PLC to control the intelligent storage cabinet, clarify the control requirements of the intelligent storage cabinet, and provide the design and distribution of solutions to meet the requirements. Reasonable input and output node ladder diagram uses the existing experimental equipment to debug the control system, complete the communication between PLC and configuration software, and achieve the expected purpose of using PLC external hardware switch and ladder diagram.Control the simulation animation in the configuration software.According to the final results, the control system designed by PLC is stable, reliable and convenient.

3.1 System design requirements
3.1.1 Hardware requirements
Intelligent storage cabinet , The control system is required to realize two modes of automatic operation and manual operation . The operation is simple and fast , Easy to use , Safe and reliable , Little maintenance , Use environmental protection and safety [10].
（1） The intelligent storage cabinet control system mainly has the following aspects ：
testing ： Intelligent storage uses sensors to scan the size of objects , Determine that the size of the cabinet is roughly equivalent to its storage . It is not allowed to store two objects in the same cabinet . The user enters the fast number for identification , And delete the corresponding object . Therefore, there must be photoelectric detection and other facilities , Find out the storage of articles and mails in time , Avoid more than one inventory , Picking up the wrong goods .
Fast and smooth ： Make sure the object is intact , Users don't need to wait for a long time , The drive is required to run at high speed , At the same time, the driver is required to have automatic acceleration and deceleration function , To ensure safety and low noise , Start and brake smoothly .
（2） The overall design task of intelligent storage cabinet system ：
The intelligent storage cabinet is made of PLC Unified management and monitoring of intelligent storage cabinets , There are two modes, automatic and manual , There are two ways to use it , adopt PLC Control the transmission device to complete the access operation of objects .
Send it ： The size of the sensor to the items sent by the user 、 Destination address 、 The recipient number and other received signals are converted into electrical signals or other required signals according to certain rules and input to PLC,PLC Move the control panel up, down, left and right , Put the sent items into a storage cabinet of appropriate size for storage [14].
Pick up ： The valid number entered by the user, such as article number 、 ID number 、 Mobile phone number, etc , The corresponding cabinet door is opened , The express is transmitted to the express outlet through the mechanical transmission device .
Besides , After the express arrives, send a text message to the user who needs to pick it up , If there is still no pick-up after two days, the second notice , If there is no pick-up after two days, notify the goods company .
The system is equipped with an emergency stop switch at the panel , In case of accident or other necessary circumstances , Press the emergency stop switch , Cut off the power supply of all motors , Stop the intelligent storage cabinet .
3.1.1 save 、 Requirements for parts taking control
Intelligent storage cabinet has storage 、 Take two functions , The following are the specific settings of the intelligent storage cabinet ：
（1） stored procedure ：
① The incoming and outgoing motors are reversed , Take out the load tray in the cabinet , The incoming and outgoing motor stops .
② The traverse motor rotates forward , Move the load tray to the leftmost end , The traverse motor stops .
③ The vertical motor rotates forward , Move the load tray down to the bottom , The vertical motor stops .
④ The window opens 4 minute , Users put items into the tray , Then close the window .
⑤ The vertical motor reverses , Move the load tray upward to the corresponding cabinet layer , The vertical motor stops .
⑥ The traverse motor reverses , Move the load tray to the corresponding cabinet door , The traverse motor stops .
⑦ The incoming and outgoing motors rotate forward , Put the load tray into the cabinet , The traverse motor stops .
⑧ It is detected that the entire intelligent storage cabinet is full , If it's already full , The display is full , And contact the goods company .
（2） Picking up process , This procedure is similar to a stored procedure , The same part is not elaborated , Here is the difference . Users need to enter the corresponding password first when picking up things , Only when the password is correct , The objects in the corresponding cabinet will be taken out , The specific steps are as follows ：
① The user enters the retrieval password .
② Whether the system identification password is correct , If correct , Show “ Welcome to use ” And carry out the following extraction process .
③ The incoming and outgoing motors are reversed , Take out the load tray in the cabinet , The incoming and outgoing motor stops .
④ The traverse motor rotates forward , Move the load tray to the leftmost end , The traverse motor stops .
⑤ The vertical motor rotates forward , Move the load tray down to the bottom , The vertical motor stops .
⑥ The window opens 4 minute , Users take items out of the tray , Then close the window .
⑦ The vertical motor reverses , Move the load tray upward to the corresponding cabinet layer , The vertical motor stops .
⑧ The traverse motor reverses , Move the load tray to the door of the corresponding cabinet , The traverse motor stops .
⑨ The incoming and outgoing motors rotate forward , Put the load tray into the cabinet , The incoming and outgoing motor stops .
