Abstract
Now the computer technology in the swift development, the microcomputer application day by day popularizes thoroughly, the microcomputer in aspects and so on correspondence automation, industry automatic control, electronic surveying, information management and information system obtains the widespread application. The embedded computer system is take the application as a center, take the computer technology as the foundation, the software and hardware may cut out, adaptation application system to function, reliability, cost, volume, effect and so on strict request specialized computer system. It application is at first based on the monolithic integrated circuit. Monolithic integrated circuit exquisite nimble, the cost is low, easy production. It faces the control, can the pointed solution from the simplicity to complex each kind of control duty. present, the domestic solar-powered water heater is also at the research and development stage, this kind of controller only has the temperature and the water level demonstration function, does not have the temperature control function. Because the heating-up time cannot control causes the overroasting, thus wastes the massive electrical energies. This design is take the 89c51 monolithic integrated circuit as the examination control center, uses the ds12887 real-time clock, has realized the temperature, the water level, the time three kind of parameter real time display functions.
