智能水箱水位控制系统设计

Design of Digital Control Current Based on Microcontroller SPCE061A

通过对单片机AT89S52的开发应用,研制了智能水箱水位控制系统,阐述了单片机及外围线路、时钟和继电器控制等电路的设计,介绍了系统实现任意时钟设置、24 h内可以任意设置通、、实现无人值守的模式、实现避开峰电而在谷电期工作、实现水位自动控制等功能;结果表明,设计的系统达到了节水、节电、性价比高、效率高和安全性能好等目的.

Based on the research of single-chip processor AT89S52 manufactured by STC,an intelligentized water stage real monitoring system is developed.Some technical aspects are illustrated in the paper,covering the single-chip processor and its periphery line,the types of the sensors,the signal transmitting and the power source management as well.The design of the software on data acquisition by the upper and the lower unit is also introduced in the paper.The system can implement any clock settings within 24 hours,can achieve unattended mode with lower operating costs,can work in valley electric period than the peak,and can realize automatic control of water level,which is proved to be cost-effective in water and electricity,efficient and safe in operation.
