北京理工大学珠海学院2020届本科生毕业论文Multi scene integrated intelligent desk designelectric control system designAbstractThis paper introduces the electronic control design of a kind of intelligent desk.Thiskind of intelligent desk can realize the stepless adjustment of the height of the desktop andmeet the office requirements of standing and sitting.At the same time,the desktop computercan be hidden under the table,save space while keeping the desktop simple.The entire electronic control system consists of STM32 development platform,24Vswitching power supply,power unit and 3.5-inch LCD screen with touch control.The LCDscreen is mounted on the STM32 development platform.Through the keil code developmentplatform,a graphical operation interface with control function is written to STM32.Thepower unit and other peripherals can be controlled by touching on the LCD screen.The powerunit is divided into two parts:one part is the desktop lift,which is composed of a dc driverand an electric push rod;the other part is the desktop lift,which is composed of a steppermotor drive and a stepper motor,both of which are controlled by STM32Key words:writing desk;intelligent STM32;graphical operation interface KEIL
