Alarm system and alarm method
First Claim
1. An alarm system for a vehicle, wherein the vehicle comprises a fuel pump and an engine, the alarm system comprises:
- a measuring device configured to read and obtain a plurality of rotation speed values of the engine in a real-time basis, and respectively measure a plurality of running times respectively corresponding to the rotation speed values;
a computing device configured to calculate a plurality of consuming times of the fuel pump corresponding to the rotation speed values according to the running times of the rotation speed values, respectively, wherein when one of the rotation speed values reaches a threshold, the computing device multiplies one of the running times corresponding to the one of the rotation speed values by a weighted index and then takes the one of the running times multiplied by the weighted index as one of the consuming times of the fuel pump, wherein the weighted index is positively related to the one of the rotation speed values; and
a warning device configured to generate a warning message when an accumulating consuming time accumulated by the consuming times reaches a default critical value.

Abstract
An alarm system is used for a vehicle including a fuel pump and an engine. The alarm system includes a measuring device, a computing device and a warning device. The measuring device is used to read a current rotation speed of the engine and respectively measures a plurality of running times of a plurality of rotation speed values of the current rotation speed. The computing device calculates a plurality of consuming times of the fuel pump corresponding to the rotation speed values according to the running times of the rotation speed values, respectively. When an accumulating consuming time accumulated by the consuming times reaches a default critical value, the warning device generates a warning message.
