The utility model relates to a sheet heating pad, which comprises a plurality of control areas, each of which comprises a temperature area control unit, a heater unit, a pressure and temperature sensing unit, a communication unit and a power supply.The temperature area control unit is used to receive the signal of the communication unit to control the heating of the heater unit, the pressure and temperature sensing unit is used to sense the temperature of the heater unit and the pressure it bears, and send the sensing signal back to the temperature area control unit, the communication unit is connected with a central control unit, and receives the command signal from the central control unit to control the heating. In the control area, the power supply provides the power needed for the operation of each unit.In addition to the above-mentioned mattress heating system, the system also includes a central control unit, which connects the plurality of control areas through the partition communication unit of the central control unit, and the central control unit can connect a cloud service server. Users can connect the cloud service server through the mobile communication device. A command is transmitted to the central control unit to control the heating condition of the plurality of control areas.一種床單發熱墊，該床單發熱墊包含複數個控制區域，每一控制區域包括一溫區控制單元，一發熱器單元，一壓力及溫度傳感單元、一通訊單元及一電源。該溫區控制單元用以接收該通訊單元之信號以控制該發熱器單元發熱，該壓力及溫度傳感單元用以感測該發熱器單元之溫度及所承受之壓力大小，並將感測信號重送至該溫區控制單元，該通訊單元連接一中央控制單元，接收來自該中央控制單元之指令信號以控制該控制區域，該電源則提供各單元運作所需要之電力。應用該床單發熱墊更可構建一床單發熱系統，該系統除包括上述之床單發熱墊外，更包括一中央控制單元，透過該中央控制單元之分區通訊單元連接該複數個控制區域，該中央控制單元更可連接一雲端服務伺服器，使用者可透過行動通訊裝置連接該雲端服務伺服器傳送指令至該中央控制單元以控制該複數個控制區域之發熱狀況。
