The Design And Implement Of The Power Load And Distribution Monitoring Terminal Based On ARM

The power load and distribution monitoring terminal is an information acquisition,processing and real-time monitoring system with computer application technology,modern communication technology and automatic control technology.It is an important part of power load management system,it plays an important role in realization of power marketing,customer service,demand side management and so on.With the opening of electricity markets around China,power companies are looking for ways to improve their efficiency and confidence to gain client's preference and confidence.Electrical equipment through real-time monitoring of management will enable enterprises to better power supply to provide quality services to customers. For special transformer,state Area,and other large users of electricity scattered occasions,it is necessary to realize the scene management of electricity,electric energy remote communication technology is very important.Because GPRS wireless network technology has entered the mature stage,it can meet the demand of the enterprise.The power load and distribution monitoring terminal based on GPRS has been programmed and researched in this thesis aiming at the problem of data communication for the automatic reading meter system.In hardware design,AD's energy measurement chip ADE7758 is used to acquire the parameters of the power grid after comparing with the common solutions.In accordance with the national standards for power quality,the solution combined the chip ADE7758with the LPC2134 of ARM7 series featuring high processing speed and pipeline organization.So the whole system will realize several functions such as electric energy acquisition,data storage,malfunction alarm,etc.Meanwhile,the module of GPRS TM900 is used to report the fault to the upper machine and clients accurately and timely.And it realizes network of power quality monitoring.he whole software design is based on ADS 1.2,the ARM development platform. The modular design method is applied in the software.It is good for the software's modification and debugging.At the same time,a new design architecture under the patterns of timer-triggered is applied in this paper and it resolves the difficulty of dispatching multitask.The experiment results show that the monitor works effectively and has a good stability,strong anti-interference capability.It also matches the national standards and could be in operation.
