Real-time embedded LINUX operating system software platform;
High performance 32-bit embedded RISC CPU (ARM9 core) hardware platform;

1. Meter reading function: 16 separate optical communication interface for the connection of 16 optical fiber meters to read the accumulative energy and other information of the meters automatically according to preset reading cycles, capable of multi-tariff and multi time frames reading, and provided with the functions to perform real-time general reading and random reading according to the control center commands received;Supporting DL/T 645 and other communication protocols; 

2. Remote communication: supporting multiple communication interfaces for the users to select according to their requirements: GPRS/ /CDMA/Ethernet/EPON and others;

3. File automatic reporting: separate channel for every down link meter reading channel, supporting initiative reporting of meter address and other parameters, as well as new installation, meter removal and other events;

4. Power failure reporting: provided with super-capacitor backup power supply, capable to operate for a period after main supply failure, so as to complete power failure event reporting;

5. Abnormal monitoring alarm: capable of initiative reporting when it monitors and Energy consumption abnormal of the users;

6. Timing function: supporting master station remote timing, supporting the timing by meter and other devices capable of timing functions;

7. Supplementary reading function: supplementary reading will be implemented to the energy meters not read in specified period, until the data of the meters being collected; And the energy meters that no data has been read in the specified reading interval will initiatively send the alarm to master station, and store a certain amount of abnormal records for the master station to call for inspection.

8. Event logging: to classify important events and ordinary events for records according to the preset event attributes; Supporting initiative reporting of alarm information of important events to the master station under balanced transmission channel; Capable of storing nearly 500 event records; 

9. Interface indication: the upper panel is provided with power supply indicator, alarm indicator, uplink communication indicator, Ethernet indicator, 16 POF optical fiber connection indicator for relevant function indication respectively; The lower panel of the terminal is provided with power supply indicator and network indicator, for GPRS module power supply status and GPRS network connection status indication respectively;
