In sum, a kind of embedded center monitoring of the present utility model system, it has following characteristics:

1, the technical grade standard design is reliable and stable, and the band accumulator can 7 * 24h operate as normal;

2, installation is simple and easy, and deployment in 3 minutes finishes;

3, adopt screen displaying, processing ease, directly perceived;

4,1 road RJ45 network interface is supported the TCP/IP networking, and the centralized management end is powerful, can do interface with operation system;

5, based on the ARM9 embedded OS, safety is virus-free;

6, support local store historical data (SD card and flash);

7, can not rely on central machine room network break-make at autonomous sound and light alarm in this locality etc.;

8, wiring is simple, can be networked directly in the centralized monitoring system.
