学生公寓电量监控系统的设计

AbstractWith the development and rapid application of information technology,powermanagement has also stepped into the information track rapidly.In order to make upfor the functional and structural defects of the current apartment electric managementsystem,it emphasizes the improvement of the power management system in securitymonitoring and so on and the structure of the system,and strengthens the terminalfunction of the system.This paper analyzes the development trend of collectiveelectricity management in domestic dormitories,and combines the existingconditions to design the current situation of low automation level and high failure ratein the current dormitory power supply network.A monitoring solution for dormitorypower consumption under smart grid is proposed.The system takes the MCUAT89S52 as the control core,and sends the digital amount to the single chipcomputer for data processing,and then displays the real time value of the voltageand current,the power and so on through the LCD liquid crystal.SPI serial bus andanalog and digital function modules are integrated,which simplifies the design ofperipheral circuits.It can realize real-time monitoring of the operation state of thepower grid,remote control the disconnection and closure of high voltage fuse,electric energy measurement and the analysis of the historical electricity use.Compared with traditional design,the system avoids the trouble of wiring and makesthe dormitories look more neat and clean.At the same time,modular design,systemmaintenance is more convenient,expansibility is enhanced,and is suitable formanaging collectivized dormitories.Key words:safe power consumption single chip microcomputerpowerconsumption monitoring.
