The invention relates to a power consumption signal acquisition device integrated with various interfaces, and is used for acquiring power consumption signals of chips of corresponding interfaces during operation in the field of information security. A plurality of communication main interfaces including I2C, SPI, SWP, UART and the like are integrated in a reader-writer, the reader-writer can communicate with a target chip of a corresponding slave interface, the reader-writer is connected with a current probe in series to supply power to target equipment, and the power consumption change of the target chip is represented by collecting signals of the current probe. The device is characterized in that the communication interface of the reader-writer is controlled to communicate with the target chip through a computer, an oscilloscope is triggered through a port (TRIG OUT) of the reader-writer, and the oscilloscope is connected with a current probe in series connection between the reader-writer and the target ch
