Fluid food oral cavity sensing and electroencephalogram signal synchronous marking system and method

The invention discloses a fluid food oral cavity sensing and electroencephalogram signal synchronous marking system and method, and belongs to the field of neurophysiological electric signal acquisition and processing. The synchronous marking system comprises a hardware control module, a software control module, an oral cavity sensing module, a signal synchronous marking module and a terminal control module, components adopted by all the modules can be manufactured through a mature technology or directly adopt existing standard components, and compared with an existing commercial injection pump or peristaltic pump scheme, the manufacturing cost of the system is remarkably reduced; the Arduino main control board is rich in interface, friendly in programming environment and capable of being additionally connected with a Bluetooth module, the functions of controllable injection capacity, injection sequence and injection speed, synchronous marking of electroencephalogram signals and the like can be achieved witho
