Design of Signal Generator for Opening/Closing Doors of Subway Trains Based on Touch Screen
When debugging subway train doors,multiple door opening and closing tests are required and the number and cycle of each test are different.Traditional testing devices cannot quickly modify the number and cycle of door opening and closing tests.To improve the efficiency of subway vehicle door opening and closing tests,a 7-inch touch screen based subway vehicle door opening and closing signal simulation generator has been developed.The device consists of a 7-inch touch screen and a motherboard,and the two communicate through USART for data exchange.The motherboard is an independently developed integrated circuit board,with the Atmega16 microcontroller as the core,controlling two high/low level signals to drive subway vehicle door opening/closing signals and one micro buzzer signal.This design scheme can fully achieve preset functions and has the advantage of intelligence,which is worth promoting and applying in the industry.
