The multi-channel signal acquisition equipment comprises a main control chip STM32, a lip language sensor signal acquisition module, a data transmission module and a data storage module, the data transmission module comprises a wired data transmission part and a wireless data transmission part, the wired data transmission part comprises an RS232 serial port transmission part and a USB2.0 transmission part, and the wireless data transmission part comprises a wireless data transmission part and a wireless data transmission part. The wireless data transmission part comprises Bluetooth V2.1 + EDR transmission, and the data storage module comprises a flash chip used for short-term data storage and an SD card used for long-term large-capacity data storage. The defects that a traditional data acquisition device is few in signal acquisition channel and data is prone to being lost are overcome, similar lip languages can be distinguished through difference signals of different sites in multi-site signal acquisition, an
