Rent a car design of the control system of the meter Transporting people in the morning from their homes to their works and back in the afternoon has bee a big problem in big cities especially in undeveloped countries. As a partial solution of this problem, the authorities in some countries had,unofficially, left the taxicab drivers to carry different passengers to different places at the sametime. For example, a taxicab with four seats may carry four different passengerswithout any relation between them except that their way of travelling is the same. Accordingly, it has bee very difficult to rely on the present conventional singlechannel taximeter to determine the fare required from each passenger separately. Accordingly, an unfair financial relation was created between the taxicab driver, owner, passengers and the state taxation department. Under these circumstances, taxicab drivers force the passengers to pay more than what they should pay. In some cases passengers had to pay double fare they should pay. With the present conventional singlechannel taximeter, taxicab owners are not able to determine the daily ine of their taxicab. In some cases (a taxicab with four seats) they may only get one quarter of the ine of the taxicab (collected by the taxicab driver). From which they should pay the salary of the taxicab driver as well as the cost of fuel, minor and major repairs in addition to the car depreciation. As a matter of fact the position of the taxicab owners is not so bad as it seems. A general agreement has been reached between the taxicab drivers and owners such that the drivers should guarantee a fixed daily ine to the owners as well as the paying for the cost of fuel as well as the minor repairs. Even though the taxicab drivers still share the large portion of the ine of the taxicab. Also with the presence of the singlechannel taximeter, it has bee very difficult for the state taxation department to know the yearly ine of the taxicab and accordingly it has bee very difficult to estimate the taxes to be paid by the taxicab owners. In order to face this problem, the state taxation department had to impose a fixed estimated 23 tax for each seat of the taxicab whatever the ine of the taxicab. In this paper, we introduced a multichannel taximeter that can deal with more than one passenger simultaneously. I t should be pointed out that by the term passenger we mean a one person or a group of related persons. I t should also be pointed out that our proposed multichannel taximeter is not, simply, a multi display readouts. As a matter of fact it contains logic automatic change circuit the fare per kilometer of travelling distance or per minutes of 39。waiting time according to the number of passengers hiring the taxicab. In the following part and as an example, we will present a plete design for a threechannel diagrams as well as detailed circuit diagrams of the experimental threechannel taximeter are also included. A prototype has been built under grant from the Egyptian Academy for Scientific and Technological Research. 24 外文翻譯 出租車計價器控制系統(tǒng)的設(shè)計 本文提出了一種出租車多通道計價的方案，能同時處理一個以上乘客的情形。為了從理論上說明本方案，提出了一個實驗上的三通道類型的士的完整設(shè)計。 在不發(fā)達(dá)的國家，早上把人們從他們家送到工作的地方，然后下午送回來已經(jīng)成為一個大問題，尤其是在大城市。作為解決這個問題的一部分，在某些國家，出租車用來解決這個問題，送人們從一個地方到另外一個地方。例如，出租車的四個席位可以攜帶四個不同的沒有任何關(guān)系的乘客，除了他們的路線是相同的。 因此，依靠目前的傳統(tǒng)的單車道計價以確定所需的票價，把每個乘客的計費分開，這已經(jīng)成為一個非常困難的問題。因此，在出租車司機，車主，乘客和國家稅務(wù)部門之間存在著不公平的財政關(guān)系。 在這種情況下，出租車司機強迫乘客支付多余他們所應(yīng)付的。在某些情況下，乘客支付了他們應(yīng)付車費的雙倍。 本常規(guī)單頻道計程車，出租車司機不能夠確定出租車日常收入。在某些情況下（出租車的 4個席位），他們可能只有出租車四分之一的收入（大部分的出租車司機）。從這些支付工資的出租車司機以及作為燃料費用外，還要維修以及汽車折舊等費用。事實上，出租車業(yè)主并非如此糟糕。一項在出租車司機與車主之間的協(xié)議已經(jīng)達(dá)成，司機應(yīng)該保證每天固定收入，以及向業(yè)主支付燃料以及維修的費用。即使如此，還是有的出租車司機的很大一部分份額之收入的出租車 。現(xiàn)在還存在的單聲道計價，已經(jīng)變得非常，國家稅務(wù)部門也知道這種困難，每年估計出租車業(yè)主的收入支出，以及應(yīng)支付 的稅務(wù)也很困難。 為了應(yīng)對這以問題，國家稅務(wù)部門已實行固定估計稅，每個座位的出租車不論收入。在本文中，我們介紹了多通道的士計程表，可以處理超過一名乘客同時進(jìn)行的情況。我應(yīng)該指出，我所說的長期旅客指一個人或一組相關(guān)的人 。我同時也應(yīng)該指出，我們提出的多渠道的計價，不是簡單的說，一個可以 顯示 多個 讀數(shù) 的計價器 。作為一個先進(jìn)的事項，事實上它包含邏輯電路，可以自動計算變化的車費以及每公里行走距離或每分鐘的候車時間按照乘客人數(shù)雇傭出租車。在下面的部分，我舉出一個例子，我們將介紹一個完整的三通道計價。框圖以及詳細(xì)的電路圖，實驗三通道計價功能也包括在內(nèi)。原型下已建成。
