In order to develop a new tool for preventing freezing injury in plastic film greenhouses in southern China, a intelligent warming device for plastic-film greenhouses was designed and evaluated. After these temperature data were analyzed by a program in the micro controller, a rotating signal was sent to the micro motor that drives the device cover. In order to ensure device reliability, the ignition system keeps working until the wick s ignited or the ignition system starts 3 times. The device was made of iron, and it was designed to seal. It is safe for the device to work on any alcohol level in tank. A 7.4V lithium battery was used to power the device. Based on that design, it can control the heat supply precisely following the variation of greenhouse temperature. This experiment showed that the intelligent warming device has convenient operation, lower cost, rapid warming characteristics, and will satisfy environmental protection objectives.
