ABSTRACT
As the standard of living has continued to improve, and the quest for comfortable and
convenient living environment there are increasingly high requirements. It is in the
living environment is an integral part of the water, and invent a lot of utensils to use
water to make it easier for people's lives. For example, a city on the roof top tanks and
rural self-built roof tanks, and so on. But it was in use in the process of water will also
be accompanied by a number, it is difficult to deal with the problem of the control level
in the reservoir, which is particularly striking. Research has found that single-chip
multi-purpose, high-performance, low-voltage, low power, low-price. Therefore, using a
single chip to control level in the reservoir can greatly reduce inputs and has a high
economic value and utility. The tank water level control system design from the main
control chip, test the circuit, circuit, manually indicator circuit, clock circuits, alarm and
water units, with the main control chip is AT C 2051 89, circuit-level water level
sensors to capture high-feed AT C 89 2051, when Upper level in the reservoir water
level is higher than the yellow light comes on, alarm, a water pump, and the stopped,
the water tank to stop; when the water tank level drops below the low water level, when
the blue light comes on, and pump alarms, begin to turn the water tank, and began to
deliver water level in the reservoir, the water level is up and down between the green
light comes on when the original work, and when the level in the reservoir is in a state
of chaos, pump stops, red light is on, and alarm. Circuits for automatic and manual
conversion, full automatic mode, the system automatically determines the water level in
the work and select a different state. In manual mode, the pump can be run manually
control your own actions. Using a single chip to control water tank, and for improving
the productivity and quality of the product, energy conservation, and others have a
positive significance.
Key words: Single chip microcomputer; water tank; water tank of control
