燃料盒14壓力與燃料盒14的充滿度及盒溫度有關。 由設計’燃料盒14的製造廠商掌握了在燃料盒事實上空 並僅有燃料供剩餘燃燒過程之有限次數時的燃料盒壓力 在此情況下,工具可能只能再起動1〇_25次,次數係取 於工具消耗量和溫度。然而,根據燃料盒 容 結合的工具規格以及溫度,使這個值可能有變化= 2適合於與本發明系統3q_起使用之卫具Μ的設計 处人6V的電壓舁貝際上空之燃料盒的-閾值(threshold); 樣’為了指示使用者燃料盒Μ即將須更換,系: 到應:疋在〇·6伏特閾值處以提示使用者這個狀態。監; ;的壓力脈衝㈣這個預定值相比較,或者,在一些情; 的已疋:τ燃燒盒之各種含量或燃料罐充滿/ 的已知值茱編成一表格,LV、ai — 一 測疋燃料罐的實際充滿度。爲 10 I254768 、、’、上述範例,5伏特 - f 了表不孟或罐是滿的,2.5伏特表示半 “ ’ 1·〇伏特表示幾半处 人 工的益’0.6伏表示一實際上空的盒。 充滿度表也可以包含隨溫度的壓力變化。針對諸如,,滿 的’(full), “部分奋、、龙,,γ !刀兄滿(Partly fun)或“空的,,(empty) ,基本讀數,由監測器32給的虔力讀數通常已經足夠,因 7溫度已經包含在壓力中。如果需要更精確的讀數,則可 太、’、料益14的操作附近配置一個用來測量燃料盒溫度的 可選擇溫度感測器4〇。 *如上述’假定燃料狀態監測器32是壓力感測器,則通 $該感測器被配置以輸出與被檢測壓力量成比例的電壓。 k個迅c和由/皿度感_ g 40輸送的任何信號被送至一控 制單元,該控制單元較佳是一微處理器/微控制器、42。較佳 是該微控制器42是已配置在工具10中以執行其他控制和/ 或排序任務,然而也可以預期本發明系統3〇係配置—指定 微控制器^微控制器的功能是否由原本存在的控制器還是 由一獨立單元併入,則取決於具體之應用。 微控制器42設置有若干預定電平(levels)(在上面的範 例中爲5.0伏特,2.5伏特,U伏特和〇·6伏特)並將類 比信號轉變爲數位值(應了解,這些電遷預定值僅爲範例 之用,並可變化以配合具體之應用)。這些值有指定的數字 標該(numerical designations),例如 5 0 你壯—,广 % =255,2·5 伏 特=128」L0伏特=50和〇·6伏特=3〇。由於系統%的主要 目才示疋爲工具1 〇的使用者提供是否燃料盒1步 一 观· 雨要更換的 -和示’所以“實際空的”之基本間值可能是使用者全部 11 I2s4768 所需的資訊。可預期是通過對每一種類型工具ι〇 燃料盒14的試誤過程( 值。 (tnal and error process)會導出一組閾 爲了範例目的,假定燃料盒14是,,實際空的”且於測 ,、·料的信镜。因爲它低於閾值,所以微控制 盗42將檢測到小於3 、, ?工市」 0的數字並發送信號至用來顯示殘留 孟:剩餘燃料量的指示器44。於此較佳具體實施例中, :44可頦不出對應於燃料盒14中燃料含量的一系列
