Taking care of patients requiring intensive-care or bedridden patients is extremely difficult, especially when cleaning up urine and feces of the patients. By using a smart bed system of the present invention, the angle of a bed can be automatically adjusted when a patient defecates, so that the patient can conveniently defecate and the guardian can be notified of the defecation to take care of the patient more comfortably. A smart supporter or a defecation container of the smart bed system generates a sensing value when sensing the urine and feces, and transmits the sensing value to a smart device of the guardian so that the guardian can adjust the angle of the upper or lower side of the bed.중증환자 또는 와상환자를 돌보는 것이 무척 힘들다특히 대소변을 처리하는 것이 힘들다.스마트침대시스템을 이용하여 대소변시 침대기울기를 자동으로 조정하여 환자가 편하게 대소변을 보게 하고 보호자에게 대소변을 알려주어 환자를 좀 더 편하게 돌보게 하는 방법이다
