Design And Implementation Of Electric Energy Remote Intelligent Terminal Software System

The development of economy and science and technology Chinese in recent years very fast, the corresponding level of communication, electronic level,software development level of development is a thousand li a day, and thereforeto a not negligible role in order to bring forth the new through the old electricalenergy of the products. Electric energy remote terminal on the true meaning of the first appeared in the 2005. This year, China Electric Power Research Instituteintroduced the concept of substation electric energy remote terminal unit. Electricenergy remote terminal and composed of electric information acquisition systemcomplete the electric energy data acquisition system of the main station, electric energy meter and communication channel, used in all levels of dispatchingSettlement Center for electric information acquisition.This thesis research is to develop a set of "electric information acquisition systembased on the" power user electric series of standards(2013 Edition) and conform to the electric power dispatching data network dual plane electric energy remote terminal embedded software system, electric energy remote terminal software system on communication through Ethernet communication mode and electricitystation information collection system system of communication, communication isunder the electric energy data reading meter, and stored in the terminal softwaresystem of electric energy remote database. The involved theoretical contentmainly includes the ARM9 clipping kernel version 2.6 of the Linux operating system module, serial port customization module, network and serial port communication layer module, software system application module. A new generation of electric energy remote terminal Ethernet communication port to four, fully adapt to each area dispatching data network communication requirements of dual plane. Now, most manufacturers to develop ARM or PC104 hardware platform based on. According to the optimal stability and product development difficulty of the principle, selection of 32 bit ARM9 kernel processorhardware development platform. Because the hardware development platform based on ARM9 not only developed quite mature, and the use of resources andhigh rate of performance to price ratio. The main task of this thesis is the development of the embedded software system on this hardware platform. The operating system uses embedded operating system Linux. The development of language using standard C language, development tools using gcc compiler.The paper "the electrical design and implementation of" energy remote terminal software system of intelligent electric energy remote terminal accords with the history of the development trend and the development objective law, to enhance the power system of "power user electric energy data acquisition system hasgreat promoting function, making the whole acquisition system tends to be morestable. The electric power market prospective is strong, broad business prospects.
