Detailed Product Description

General Introduction:
Mini-wireless concentrator is the key equipment inAMR system: adopting 32-bit ARM as processor; large-capacity FLASH as storage space for historical data; high-performance RF chips as transceiver for wireless data; the SETNET wireless network for meter reading. Main station management related to on-site meter can be carried out through concentrator which is in line with the PRC Power Industry Standard DL/T 698-1999 Technical Requirements of LV Auto Meter Reading (AMR) System.

Functions and Features:
1. Administrative capacity: 1260 meters.
2. Automatically collect and store the meter data of total, sharp, peak, shoulder and off-peak.
3. Store daily consumption data at the zero point in favor of the calculation of line losses.
4. Automatically store the consumption data monthly.
5. Automatically store the consumption data of primary consumer hourly.
6. Automatically store the load curve of meter fitting to transformer distribution area.
7. Report data on its own.
8. Full-auto functions: network organization, routes optimization, nodes searching and deletion.
9. 10-class routing, maximum support: up to 1024 nodes.
10. Robust mesh structure with stable performance and high reliability.
11. Plug and play; auto network organization without the on-site artificial setting.
12. Wireless measure frequency (470-510MHz) for free, multi-frequency can be set.
13. Strong penetrability at long bowls with over 4Km network coverage radius outside.
14. Carrier communication with 3-class auto-routing.
15. Auto add-reading.
16. Pick-reading.
17. Remote monitor.
18. Broadcast freezes.
19. Remote stitching control.
20. Flexible uplink channel (optional: standard RS-232, MODEM, OPRS, CDMA).
21. RS-232 flexible protocol supports breakpoint resume.
22. Lightning proof.
23. Auto broadcast time synchronization.
24. Remote software upgrade for concentrator through GPRS and the MODEM from the main station.
25. Local software upgrade for concentrator through RS232 from the main station.
26. Cascade connection function: concentrators can be connected as a whole via RS485 and then communicate with main station
27. directly or in virtue of GPRS to facilitate meter reading in residential area.
