衡器偏載調(diào)節(jié)的目的是使稱重時(shí)，同樣重量的物體無論重心處于承載器的任何位置，稱重結(jié)果均相同，即誤差不會(huì)超過規(guī)定大允許誤差。這樣的衡器也能保證四支傳感器在該系統(tǒng)內(nèi)的力矩是相等的。

The purpose of weighing instrument's bias load adjustment is to make the weighing result of the same weight object no matter the center of gravity is in any position of the carrier, that is, the error will not exceed the maximum allowable error. Such a weighing instrument can also ensure that the torque of four sensors in the system is equal.

這樣的衡器在稱重時(shí)，四支傳感器所受力值之和就等于被稱物的重量。當(dāng)測重心時(shí)，用傳感器的力矩之差就可計(jì)算出被測物的相對(duì)重心位置，即重心位置的坐標(biāo)是根據(jù)所測的力矩差和承載器幾何尺寸，通過計(jì)算而得到。所以它的測量誤差是可以根據(jù)計(jì)算重心的公式求得的，根本不需要試驗(yàn)來確定，試驗(yàn)方法僅僅是對(duì)測量結(jié)果的旁證。

When such a weighing instrument is weighing, the sum of the force values of the four sensors is equal to the weight of the weighing object. When measuring the center of gravity, the relative center of gravity position of the object can be calculated by the torque difference of the sensor, that is, the coordinates of the center of gravity position are obtained by calculation according to the measured torque difference and the geometric size of the carrier. Therefore, the measurement error can be obtained according to the formula for calculating the center of gravity, and no test is needed to determine it. The test method is only the circumstantial evidence of the measurement results.

但對(duì)于吊掛式集裝箱裝置，由于該裝置沒有承載器，且用來測量的傳感器與固定或類似汽車衡的稱重裝置不同，所以測量結(jié)果與實(shí)際被測的集裝箱的狀況關(guān)系非常大，對(duì)它的校驗(yàn)方法和結(jié)果要由基本力學(xué)原理來設(shè)計(jì)，不要輕易地用一些測量的方法來硬套，否則結(jié)果一定是不可靠、不合理的。

However, for the hanging container device, because the device has no carrier, and the sensor used for measurement is different from the weighing device fixed or similar to truck scale, the measurement result has a great relationship with the actual condition of the container to be measured. The calibration method and result of the device should be designed by the basic mechanical principle, and it is not easy to use some measurement methods to rigidly cover, otherwise the results will be obtained It's not necessarily reasonable and reliable.

由于微處理器、計(jì)算機(jī)在稱重工程中的廣泛運(yùn)用，特別是當(dāng)今互聯(lián)網(wǎng)、大數(shù)據(jù)的飛速發(fā)展，衡器行業(yè)中很多有識(shí)之士都著重借助這些技術(shù)來發(fā)展衡器行業(yè)。但從另一方面考慮，一些初涉及衡器行業(yè)的人往往忽略了衡器的基本原理和規(guī)律，在工作中容易犯一些低級(jí)錯(cuò)誤，產(chǎn)生認(rèn)識(shí)上的混亂，造成工作中的失敗。

Due to the wide application of microprocessor and computer in weighing engineering, especially with the rapid development of Internet and big data, many people with insight in weighing instrument industry focus on these technologies to develop weighing instrument industry. However, on the other hand, some people who are initially involved in the weighing instrument industry often neglect the basic principles and laws of weighing instrument, and are prone to make some low-level mistakes in their work, resulting in confusion in understanding and failure in work.

更遺憾的是，他們往往還不知道錯(cuò)在何處，還試圖通過所謂的“新理念”、“高科技手段”來解決問題，但這些努力是徒勞的。

What's more, they often don't know what's wrong and try to solve problems through so-called "new ideas" and "high-tech means", but these efforts are in vain.
