Defecation sensing, identifying and processing system

The invention provides a defecation sensing, identifying and processing system, which comprises a bed pan, a bed pan sensing plate arranged in the bed pan and a bed pan host communicated with the bed pan sensing plate. The system is characterized in that a main control chip, a defecation and urine sensing numerical value calculating and processing chip connected with the main control chip, and a urine sensing area, an auxiliary sensing area and a defecation sensing area which are respectively communicated with the sensing numerical value calculating and processing chip and are arranged in sequence are arranged in the bed pan sensing plate; the defecation sensing numerical value calculation processing chip can judge whether an excrement signal or a urine signal is sent to the main control chip, and then the main control chip enters a defecation processing mode and a urine processing mode according to excrement and urine information. By means of the specific capacitive sensing chip arrangement and calculation m
