本論文為智慧型災害防範系統設計了一套省電的策略，智慧型災難防範系統是指所有利用通用標準化的災難資訊來做防災的應用程式或是裝置，這樣的應用程式或是裝置能幫助人們更快速準確的進行防災的動作，然而，智慧型災難防範系統有可能是利用電池供電的，當他們是利用電池供電的系統時我們就需要考慮電量的消耗問題，若是電量消耗過快就會影響到這個系統的正常使用，正如前面所說，智慧型災難防範系統是透過接收通用標準化的災難資訊來做應用，所有的災害種類都會用同一種格式發出，因此智慧型災難防範系統所接收到的災難資訊未必是他所需要去處理的，只要接收到一個不需要處理的災難資訊系統就會多浪費一分電，我們的省電策略就是針對這個問題進行考慮，讓系統能夠在災接收到不需要處理的資訊時消耗少一點的電。

The intelligent Guards against Disasters (iGaDs) can receive emergency alerts such as CAP messages and take appropriate actions to protect people and their property. However, the performance of mobile iGaDs are limited by the battery life. In this thesis, we present a method to save the energy consumption on a mobile iGaD. We also compare the method to the other exist energy saving methods on mobile devices. Finally, as a primitive attempt, we use evaluation boards to emulate our method.
