This article proposed one kind of intelligent monitoring and the dispatch automated system with low power loss using modern examination technology, the GPRS wireless communication technology and the hypothesized instrument，in order to solve traditional industrial control emerges several regrets such as low efficiency and resource wasting. this system can achieve some function such as real-time monitor the electrical network running status, long-range control high voltage fuse separation and closed and the electrical energy measurement as well as the history uses electricity the condition to carry on the analysis and so on. The system adopts the idea of modularization design, which includes the electrical network parameter gathering, the long-range control, the system charge, pressure examination and so on. It uses With 8051 F330D as its testing and controlling center, which has abundant hardware resource. 8051 F330D integrates SPI serial bus and digital functions. The designing of electric circuits are easier by using the same MCU. Using trusty communication protocols, the system can meet the requirements of high dependability. The gathering module selects three-phase electrical energy special-purpose DSP chip ATT7022A, this chip transforms 16 A/D with 24 DSP technologies combines, increased the survey precision greatly; The MCU and ATT7022A transfer data by SPI serial bus which adopt Principal and subordinate way. In view of electrical network monitoring to communications system's request and full consideration correspondence moves under the low cost premise, selected GPRS to realize the monitor terminal and the monitoring center correspondence; The computer and MCU can achieve transfer parameter and remote control through the GPRS wireless network, thus the design is realized to real-time monitor the power network conditions. The system’s software adopt the test software under the LabWindows/CVI6.0 which includes data processing program, the dynamic data exchange (DDE) and so on, it can complete data statistical processing and instruction data analysis. simultaneously we have established the visualization program to realize the data monitor, analyses power consumption Status and Make report forms functions.The system has abundant functions and has many merits, such as convenient operation, low cost, convenient to setup and maintenance, easy to development and extend.
