Abstract
With MCU development, which in complex control systems, intelligent systems have broad application. High-speed large-functional single-chip microcomputer increasingly improved to meet the many complex areas of the "scene control" Its appearance in the major application areas caused a lot of repercussions. And the MCS-51 in the field of computer plays an important role.
Designed to achieve this drying plate keyboard vacuum right time and exposure control. Vacuum pre-set time, the exposure time parameters, and the preservation of the EEPROM, Boot automatically read from the EEPROM parameters. Digital vacuum tube time, exposure time, using LED indicates the current state of work. Work with the countdown displays the remaining time to time when the regular, open or close the corresponding relay.
This paper describes the design of the current, mainly used in the AT89C2051, CD4094. 24C02 chip, involving mainly module and control module, and the application of the tools Protel, such as proteus.
