Abstract
In recent years along with the technical swift development, monolithic integrated circuit's application was moving toward unceasingly thoroughly, simultaneously led the traditional control examination, the Japan crecent moon profit renewal. In the real-time examination and in automatic control's monolithic integrated circuit application system, the monolithic integrated circuit often is takes a core part to use, The monolithic integrated circuit is integrates the main computer functional unit on a chip the microcomputer. It is one kind of collection counting and many connections in a body's micro controller, is widely applied in the intelligent product and in the industrial automation, but 51 monolithic integrated circuits are in a monolithic integrated circuit are most typical and the most representative one kind. The water tank intelligence water level's control system must first be able to examine the water level correctly and can demonstrate correctly that and has the prompt adjustment water level function. The system takes the control core by AT89S51, the monitor, the driving circuit and so on unifies completes the water monitor, has displayed monolithic integrated circuit's performance fully. Its hardware circuit is simple, the software function is perfect, the control system is reliable, has certain use and the reference value.
