UPGRADED electricity meters, to work with the SAP ERP system

摘要

The present utility model relates to electric engineering, commercial accounting of electric power monitoring and alarm state of the three-phase electrical network, in particular to multifunction multirate instrument of electric energy designed for the operative control of electric power parameters, power and state electrical network in power supply systems for energy facilities, with the possibility of transmission of information in the software database SAB ERP system via radio. Upgraded electrometer, working with SAB ERP system comprising a terminal block that connects the power supply and blocks voltage sensors and current to the mains, the microcontroller is connected via an analog-digital converter to supply voltage and current sensors, and coupled to the RS-485 interface, an LCD screen , LED display of the device, an optical port, radio unit connected to the power unit and supporting, but not limited to data transmission standards GSM, CDMA and IEE 802.11, redundant IP regular enrollment supply built into the microcontroller clock and power unit, the nonvolatile memory comprises a connector for connecting additional memory registers, in one of which the recorded geographical coordinates and operative here device installation location, the smooth operation of the device provides a battery connected through a backup power source connection socket to the power supply, as the connector is connected to the microcontroller and radio unit. device feature consists in that the nonvolatile memory comprises a further memory register containing the access code into the soft SAB ERP system and location information about technical technical object to which the device is attached.
