The invention discloses a dual-DSP architecture-based special line user energy-saving diagnosis apparatus and energy-saving diagnosis method. The special line user energy-saving diagnosis apparatus includes a prepositioned wiring part, a signal sampling unit, a DSP signal processing unit, a man-machine interface unit and a power supply unit; the signal sampling unit, the DSP signal processing unit and the man-machine interface unit are connected with one another sequentially; the signal sampling unit comprises a signal sensing unit, a signal conditioning unit and an ADC sampling unit which are connected with one another sequentially; and the DSP signal processing unit comprises a 1# DSP unit, a dual-port RAM and a 2# DSP unit, wherein the 1# DSP unit, the dual-port RAM and the 2# DSP unit are connected with one another sequentially. According to the special line user energy-saving diagnosis apparatus of the invention, a dual-DSP structure is adopted, and the dual-port RAM is adopted as a communication bridge between the DSPs, and therefore, data processing fast and accurate. The special line user energy-saving diagnosis apparatus has the advantages of simple operation, low cost portable, probable convenience, easiness in popularization, high precision, strong anti-interference ability and the like.
