基于8051单片机的水箱水位控制系统的的设计.doc

摘 要 随着生活水平的不断提高，人们追求舒适、便利的居住环境的要求也越来越高。人们居住环境中不可或缺的是水，发明创造了大量的器具来使用水以求方便人们的生活。比如，城市楼顶蓄水池和农村居民自建房顶蓄水箱等等。但是人们在使用水的过程中伴随着也会出现许多难以处理的问题，其中水箱水位的控制尤为突出。科研中发现单片机具有多功能、高性能、低电压、低功耗、低价格的显著特点。所以利用单片机对水箱进行控制可以极大的减少投入，具有很高的经济价值与实用性。利用单片机实现水箱控制，对于提高劳动生产率和产品质量，节约能源等都有着积极意义。 关键词：单片机；水箱；水位控制  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 peoples 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 automatical
