The utility model relates to a multi-channel bearing state remote monitoring device. The device comprises a data acquisition module, a data preprocessing module, an upper computer and a display module, the data acquisition module is composed of a plurality of composite sensors; the data preprocessing module comprises a channel switching circuit, a signal conversion unit and a signal processing unit; the wireless communication module is used for transmitting the sensor data file processed by the data preprocessing module to an upper computer and receiving an instruction of the server to control the data acquisition module to acquire data regularly; the upper computer is used for analyzing the received sensor data file and prompting abnormity; and the display module is used for receiving and displaying the abnormity prompt of the upper computer. According to the utility model, the data pre-processing module and the sensor are separately designed, so that the miniaturization of the sensor is facilitated, the sen
