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.

LED Functionality:

LED Display Indicator status
Rate of consumption (Red LED)
Flashing Red LED indicates the rate of electricity consumption. A fast flash indicates high usage while a slow flash indicates low usage
Alarm/relay status/ communication (bi-colour LED)
RED: indicates relay disconnected (high priority) FLASHING RED: indicates tamper event occurred GREEN: MCU and UIU communicating
Remaining Credit Status (bi-colour LED)
GREEN: Remaining credit exceed the high credit threshold RED: Remaining credit below the high credit threshold FLASHING RED: Remaining credit below the lowlow credit threshold
FLASHING RED with BUZZER: Remaining credit below the critical credit threshold. Note: when the meter in the postpaid mode, LED is GREEN

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:

Display Description
Recharge successfully
Recharge credit is 132.50kWh
Recharge unsuccessful
Entered TOKEN has previously being entered
Recharge unsuccessful
Entered TOKEN code is correct but this recharge credit plus remaining credit exceeds maximum credit threshold
Recharge unsuccessful
Entered TOKEN older than the oldest TOKEN in the meter log (Overdue TOKEN)
Recharge unsuccessful
Entered TOKEN incorrectly entered
Recharge unsuccessful
The security key of the Entered TOKEN has expired
