专业综合课程设计Abstract This curriculum project is using monolithic integrated circuit AT89C51, clock chip DS1302, temperature sensor DS18B20 as well as 160*128 liquid crystal unitized design one section simulates ten thousand calendars, realizes the simple demonstration temperature, the time and the date function. The clock chip provides the pulse using monolithic integrated circuits crystal oscillator to control the internal timer, reads the current date and the time, and processes through the connection transmission for the monolithic integrated circuit; Simultaneously the temperature sensor will produce the simulation temperature transmits for the monolithic integrated circuit. The monolithic integrated circuit will accept the data transmission to the monitor on 160128, realizes the temperature, the date and the time at the same time demonstration. This system is mainly by the clock read module, the current temperature read module, the temperature and the time display module and the control circuit four parts is composed. The clock read part real-time provides the current time using clock chip DS1302, and transmits for the monolithic integrated circuit; The temperature extraction is reads the current indoor temperature using DS18b20; The demonstration part uses the LCD160128 liquid crystal display ten thousand calendars and the temperature. The overall system carries on the programming using the C language, meets the curriculum project requirements after the debugging simulation effect.
