ABSTRACT:
A method and apparatus for preventing an accident or a fault of a device due to heat generation by calculating a temperature of a device expected after data transmission is finished to predict a temperature of the device is provided. In this method and apparatus, first, transmission data is applied, data transmission time and the expected device temperature when transmission is finished are calculated. And data transmission is started when the calculated temperature is lower than a set value and an alarm is generated for a user and transmission remains on standby when the calculated temperature is higher than the set value. Whether or not the data transmission is performed is selected with a user interface such as a display section and dial keys. When performing the data transmission is selected, a data transmission speed is decreased and the step of calculating the transmission time and the expected device temperature is repeated. During the data transmission, temperature monitoring is performed such that the device temperature is measured to continue the transmission when the temperature is lower than the set temperature and stop the transmission when the temperature goes higher than the set temperature.
