RS485 Data Collector in Automatic Meter Reading System for Data Collecting AMI System
Main Functions:
- Data Acquisition: Multifunction energy meter data collection, 2 RS485 ports with least 8 different protocols multifunction energy meters. State variables collection, pulse collection and collection module data.
- Data Processing: Terminal can generate and store real time data, historical daily data, historical month data.
- Remote Communication: Communicate with main station, communicate with AC sampling unit and communicate with energy meter.
- Parameter Setting: Clock test and time hack, TA turns ratio, TV turns ratio, energy meter constant, limit parameter, power control parameter, energy control parameter, terminal parameter, reading parameter, etc.
- Remote Control: Power supply, reject, remote tripping and closing, local power close loop control, month power tariff close loop control.
- Event Logging: Both important event and general event will store latest 255 records. Every record includes event type, time and relevant circumstances.
- Equipment Maintenance: USB interface and maintenance RS 232 interface are used for data backup and upgrade. Software and parameter are able to be upgraded and maintained by GPRS/CDMA.
- Test Alarm: Real time monitor and control big user’s electric load, possessing anti-stealing function. Abnormal information initiative report, including default phase, undervoltage, reverse phase sequence, readings fell, communication failure, door open.
- Terminal Cost Control: Power purchasing and prepayment.
