The utility model provides a smart power grids dispatch terminal all -in -one, is embedded terminal all -in -one system, and with ethernet controller, power supply circuit, crystal oscillator circuit, reset circuit, JTAG interface, memory module, AT91RM9200 microprocessor is integrated together, constitutes the main control board, the integration of modem subtotal digital process part constructs moulding together and plans digital channel intergral template, and intergral template is the integrated circuit board pattern, pegs graft with the main control board and constitutes together the terminal all -in -one. With analog -to -digital conversion board / digital revolution letter stencil on the framework, data signal changes the integration of network signal device and at a terminal equipment, has removed outside physics connecting wire, has adopted the relation of connection of integrated circuit and contact pin. Hardware adopts the embedded type design, and software adopts the modularized design, and the implementation method is simple, has shortened the development time greatly. Powerful data redundancy has satisfied the requirement of smart power grids intelligent dispatching system to data equipment.
