Holley: Data Concentrator

Data Concentrator can communicate with software through GSM/PSTN network, or RS232. One DC can carry the energy meter nodes quantity up to 400~500pcs. Due to the geographical barriers or environment conditions, the communication distance between meters and data concentrator is very different.

For the purpose of extending the communication distance, each meter can act as a repeater up to 3 levels depth. DC has intelligent self learning ability to determine the best pathway to communicate with any specific meter. The concentrator manages meters and other devices on the downlink network and provides data transfers between these devices and the utility's System Software with uplink channel.

The main parameters of the concentrator:

• Maximum capacity for energy meter is 500pcs
• DC communicates with management system via GSM/PSTN/RS232 network, communicate baud rate is 9600bps.
• DC has Real Time Clock. RTC error is less than 0.5s per day.
• DC can freeze, read & save the meter data at setting time. It can save 31 days Daily Frozen Data of the meter (Up to maximum capacity), and 12 month� monthly frozen data. Even the power off the data can remain for at least 6 month.
• Parameters can be stored for 10 years when power is cut off suddenly.
• Password protection assures the security of the data.

• DIN-SO pulse output for KWh, high-light LED indicated for accuracy test

LED Functionality:

Recharging the meter

• After purchasing credit, the user will receive a 20 digit STS TOKEN
• The STS TOKEN is entered into the meter using the UIU keypad
• Entering the token, 10 seconds between inputting of consecutive digits is allowed. Exceeding this will result in the user having to restart the inputting process.
• The back one space clear button allows errors to be corrected.
• Once all digits have correctly being keyed in, the accept button transmits the token to the MCU meter
• The meter configuration software can also be used to enter the token into the meter

On entry of the token, one of the following responses are received:

Measurement and Billing:

• Active energy (import and export).
• Remaining credit.
• Instantaneous Measurement (V, I, kW, f, power factor).

Displays:

• Metering Unit:
• - LED indicators provide visual indication for active power consumption rate, credit status, load switch status, alarms, mains power and "communication to CIU" status.
