【Abstract】 By exploiting the operating principle of the temperature-indicating wax label and image processing technology, a novel method for remote on-line temperature detection of substation high-voltage contacts is put forward. A low cost and unmanned warning system based on the method is designed. The principle, configuration, function and some key questions about the hardware and software design of the system are discussed. In- and out-door experiments have proved that the warning system is practical and reliable.更多还原
