The Research And Design On Remote Distributed And Monitoring Terminal Based On ARM And μC/OS-Ⅱ

With the rapid development of the economy of my country, the requirement of electric power increases quickly in all enterprises. For the sake of saving energy, we increase capacity of the generate electricity at one time, and enhance the Demand-Side Management (DSM) is no time to delay, the terminal of distribute and monitor in power consumption field is a important department of DSM, it is an emergent problem that electricity supply department should solve, it has been continuously developed with the development of electric power system management automation. With the development of the management automation technology, the design of the terminal has wide foreground.The paper summarizes actuality of the terminal on DSM in different countries, analyses the status and function of the terminal on domestic DSM, and the technology level of the terminal and its design method. It provides a method to research and design the terminal based on the order of electric power company of Jiangxi province.Several technologies researched and applied in research of the thesis which includes the technique of electric energy measurement, the remote and automatic reading meter, GPRS, embedded system and remote update application in terminal. The system has advantage of execution efficiency, software cubage, and response speed and communication expense.Aim at the current practical situation, a kind design procedure is presented on terminal which based on ARM andμC/OS-Ⅱ, and selects the ARM microprocessor and operating system combine with the demand of the subject. It designs the hardware system based on the LPC2124 and the periphery interface chipset, and implements the transplantation ofμC/OS-Ⅱon the LPC2124, compiles the hardware drivers and the API based onμC/OS-Ⅱ, the system introduces multitask based on dispatching priority to solve the disadvantage of the Foreground/Background System. A kind of project on remote update software based on GPRS and IAP is presented, and discusses the reliability in the end.
