Disclosed is a direct heating system for a transport means, which can perform multi-stage heating on a seat requiring direct heating only when a person is seated, by reflecting changes in passenger density in a variety of ways. The direct heating system for a transport means comprises: a power supply unit; a composite material having a structure in which carbon heating fabrics and a piezoelectric film are laminated, and disposed in a seating area of a chair; and a main relay element forming a switching path to supply the power of the power supply unit to the carbon heating fabrics by being switched on as the piezoelectric film is pressurized to generate piezoelectric electricity. Accordingly, the multi-stage heating can be performed on the seat requiring the direct heating by enabling the carbon heating fabrics to receive the power only when the person is seated by utilizing the composite material having the structure in which the carbon heating fabrics and the piezoelectric film are laminated, on the basis of a correction temperature calculated by using a variable load value and a temperature value capable of considering the passenger density.

    사람이 좌석에 앉았을 때만 직접난방을 원하는 좌석에 승객밀도 변화를 다양한 방법으로 반영하여 다단계 난방을 수행할 수 있는 운송수단용 직접난방시스템이 개시된다. 운송수단용 직접난방시스템은, 전원공급부 탄소발열섬유와 압전필름이 적층된 구조를 갖고서, 의자의 착석 구역에 배치된 복합소재; 및 상기 압전필름에 가압이 이루어져 압전전기가 생성됨에 따라, 스위치 온되어 상기 전원공급부의 전원을 상기 탄소발열섬유에 공급되도록 스위칭 경로를 형성하는 메인 릴레이소자를 포함한다. 이에 따라, 탄소발열섬유와 압전필름이 적층된 구조인 복합소재를 활용하여 사람이 좌석에 앉았을 때만 탄소발열섬유가 전력을 인가받아 직접난방을 원하는 좌석에 수행하며승객밀도를 고려할 수 있는 응하중값과 온도값을 이용하여 산출한 보정온도를 기반으로 단계 난방을 수행할 수 있다.
