大家知道,包果收寄机收寄包果,用的是专用扇面秤。在原秤面背后,有一块模拟印刷电路板;它的刻度与原秤面相同。机器工作时,摆针触头接触模拟印刷电路板,印刷电路板将相应的重量数据变成电位信号送出,完成重量到电信号的转换。至于包果资费的计算,即包果单价和重量相乘,收寄机是以百克为单位,将单价一次一次地累加完成的(此外还要加2角手续费)。显然,为了准确计算资费,第一,机器要能自动控制累加次数,保证累加
We all know that the package fruit receipt and mail machine to receive the package fruit, using a special fan scale. Behind the original scale, there is an analog printed circuit board; it has the same scale as the original scale. Machine work, the pendulum contacts touch the analog printed circuit board, the printed circuit board will be the corresponding weight data into a potential signal sent to complete the weight of the electrical signal conversion. As for the calculation of the baguette tariff, that baguette unit price and weight multiplying, receiving machine is a hundred grams as a unit, the unit price is accumulated again and again (in addition to plus 2 fee). Obviously, in order to accurately calculate the tariff, first, the machine must be able to automatically control the cumulative number of cumulative
