Monitoring device used for power user electric energy data acquire system

Abstract

The invention discloses a monitoring device used for a power user electric energy data acquire system. The monitoring device comprises a single-chip microcomputer, a power supply, an AC sampler, a FLASH memory, a ferroelectric memory, a button, a display screen, a 485 interface, a meter reading router, a wireless network card, an infrared interface and a carrier communication interface. The single-chip microcomputer is respectively connected with the power supply, the AC sampler, the FLASH memory, the ferroelectric memory, the button, the display screen, the 485 interface, the meter reading router, the wireless network card, the infrared interface and the carrier communication interface. The power supply is connected with the AC sampler. According to the monitoring device, data transmitted by a GPRS communication channel, a power line carrier communication channel and an RS485 communication channel can be monitored simultaneously so that the state of the GPRS communication channel, the state of the power line carrier channel and the state of the RS485 link communication can be better understood.
