Certificate

 

Q/GDW 1373-2013, Q/GDW 1374-2013, Q/GDW 1376.1-2013, DL/T 645-1997, DL/T 645-2007

 

Feature

 

1. With the integration of GPRS communication technology, the power supply of the communication module can be controlled separately, which can further prevent the data communication module from crashing.

 

2. It can be connected to various domestic and oversea meter protocols at the same time.

 

3. Safe and reliable control technology with multi-level protective measures;

 

4. It has the function of active fault reporting, which can locate and solve the fault instantly.

 

5. The use of large-capacity electronic disk and embedded file management technology can ensure the preservation of historical data for a long time.

 

6. Function module remote upgrade and remote maintenance, flexibly meet the requirements of system function expansion in the future;

 

7. Advanced data compression and encryption technology.

 

Function

 

1. Using high-performance 32-bit hardware platform.

 

2. Using a stable and reliable real-time embedded Linux operating system software platform.

 

3. Modularization hardware: independent, modular design, matching with the base meter, does not affect the metering function, supports hot-swappable function.

 

4. Modularization software: the application software adopts modular programming, and each application module runs independently and does not affect each other.

 

5. The power supply of the communication module can be controlled separately, which can further prevent the data communication module from crashing.

 

6. Can be connected to various domestic and international meter protocols at the same time.

 

7. Safe and reliable control technology with multi-level protective measures.

 

8. It has the function of active fault reporting, which can locate and solve the fault instantly.

 

9. The use of large-capacity FLASH and embedded file management technology can ensure the preservation of historical data for a long time.

 

10. Remote upgrade and remote maintenance of functional module, flexibly meet the requirements of expansion on system function in the future.

 

11. Advanced data compression and encryption technology
