Features

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

2. Integrated 2G/3G/4G multiple communication technology, power supply for each module can be separately controlled, which could prevent the system halted.

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

5. Active fault reporting, which can locate and solve the fault instantly.

6. 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 expansion on function in the future;

7. Sealed design

8. Waterproof and UV-resistant, flame retardant material.

9. Advanced data compression and encryption technology

Function

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

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

3. Modularization hardware: 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 mode, and each application module runs independently and does not influence each other, so it can monitor the operation status of each module. When the module runs abnormally, it can recover automatically, thus ensuring the reliability of the software operation. The application software automatically identifies and adapts the GPRS/CDMA/3G/4G/ Ethernet module.

5. With the integration of GPRS/CDMA/3G/4G/ Ethernet and other communication technologies, 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 overseas 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. Function module can be remotely upgraded and remotely maintained, enable future function expansion for system.

11. Advanced data compression and encryption technology
