Suppose that the residents on the 4th floor are going to the 2nd floor. The elevator stops on the 1st floor, the up lights are on, waiting for passengers to ride Simulation analysis Double-click the microcontroller, load elevator.hex in the C program folder, and run the simulation. The whole system construction is as follows: After pressing the desired floor inside the elevator, press the start button, and the elevator will start to run. It should be noted that the start button is used to simulate the elevator door closing. Press the emergency stop button, the elevator stops in an emergency, the digital tube displays the current emergency stop floor, and both the up and down lights are off, indicating that the elevator is in an unavailable state. After long pressing the start button, the alarm will be cancelled and the elevator will resume operation When the elevator is running, press the alarm button, the alarm light will flash, the buzzer will sound, and the elevator will stop running. The digital tube and the LED indicator respectively indicate the current elevator floor and the elevator status the stepper motor simulates the elevator operation process (the motor rotates clockwise to increase, and counterclockwise to decrease).ДЄt the same time, this system has elevator emergency stop and alarm functions. This system uses 51 single-chip microcomputer as the control core, reads the operation buttons inside and outside the elevator in real time, and responds to the riding request in time. When the elevator is unoccupied, it will stay on the first floor by default.Use a stepper motor to simulate elevator lifting, clockwise rotation is rising, and reverse time is falling.With emergency stop and sound and light alarm functions to protect passengers' safety.The elevator floor and lifting status are displayed in real time through digital tubes and LED lights.The elevator is equipped with internal and external keys, press any key, the elevator control system responds.For resource acquisition, please see the description at the end of the article~
