Radio communication type comprehensive power distribution measuring and recording instrument

Abstract

The present invention is one comprehensive monitoring and recording instrument for power distribution system. The instrument includes ADC, CPU1 as digital signal processor, system clock and parameter memory, program and data memory, peripheral logic circuit I, communication module interface contained to CPU1 and GPRS communication card, which includes CPU2, program memory II, outer logic circuit II, communication interface module, GPRS module and SIM card.CPU2 is connected to CPU1 via the communication module and serial communication interface for data exchange while being connected to GPRS module and SIM module via serial-to-parallel converting module for data exchange. GPRS module is also connected to an antenna for data signal emission via the antenna.

Description

technical field [0001] The invention relates to a comprehensive monitoring and recording device for power quality in a power distribution system. The device integrates data collection, data analysis, data storage and data transmission, and is used for real-time monitoring and regular analysis and evaluation of power quality in the power distribution system. Background technique [0002] At present, the power quality monitoring devices commonly used in power distribution systems are composed of electrical quantity acquisition (transformer), data analysis and storage (16-bit single-chip microcomputer or DSP), data display, and communication interface (RS232 or RS485). The monitored power quality indicators are scrolled and displayed on the LCD screen, which can be viewed at the monitoring site, or the technicians regularly take a special meter reading device to the site to read the meter, and bring the read data back to the monitoring center, and input it into the computer for ...
