The invention discloses a switch machine analog signal multiplexing device and method, and the switch machine analog signal multiplexing device comprises a control unit, a plurality of first-stage multiplexing units, and a second-stage multiplexing unit. Wherein each of the first-stage multiplexing unit and the second-stage multiplexing unit is provided with a plurality of input ports, and each input port is used for collecting different analog signals; a plurality of input ports of the second-stage multiplexing unit are respectively connected with different output ports of the first-stage multiplexing unit, and the second-stage multiplexing unit is used for collecting analog signals output by the first-stage multiplexing unit; and the control unit controls the second-stage multiplexing unit to gate a specified input port in the plurality of input ports and the output port of the second-stage multiplexing unit. According to the embodiment of the invention, multi-channel acquisition is carried out on different analog signals, so that the working efficiency of the mode of acquiring the analog signals by the acquisition single board is improved.
