控制技術(shù)
DCS在控制上的大特點是依靠各種控制、運算模塊的靈活組態(tài)，可實現(xiàn)多樣化的控制策略以滿足不同情況下的需要使得在單元組合儀表實現(xiàn)起來相當(dāng)繁瑣與復(fù)雜的命題變得簡單，隨著企業(yè)提出的高柔性、益的要求，以經(jīng)典控制理論為基礎(chǔ)的控制方案已經(jīng)不能適應(yīng)，以多變量預(yù)測控制為代表的控制策略的提出和成功應(yīng)用之后，過程控制受到了過程工業(yè)界的普遍關(guān)注。需要強調(diào)的是，廣泛應(yīng)用各種控制與優(yōu)化技術(shù)是挖掘并提升DCS綜合性能有效、直接、也是具價值的發(fā)展方向。

坐標(biāo)
觸摸屏是坐標(biāo)系統(tǒng)，要選哪就直接點那，與鼠標(biāo)這類相對定位系統(tǒng)的本質(zhì)區(qū)別是一次到位的直觀性，坐標(biāo)系的特點是每一次定位坐標(biāo)與上一次定位坐標(biāo)沒有關(guān)系，觸摸屏在物理上是一套立的坐標(biāo)定位系統(tǒng)，每次觸摸的數(shù)據(jù)通過校準(zhǔn)數(shù)據(jù)轉(zhuǎn)為屏幕上的坐標(biāo)，這樣，就要求觸摸屏這套坐標(biāo)不管在什么情況下，同一點的輸出數(shù)據(jù)是穩(wěn)定的，如果不穩(wěn)定那么這觸摸屏就不能坐標(biāo)定位，點不準(zhǔn)，這就是觸摸屏怕的問題:漂移。技術(shù)原理上凡是不能同一點觸摸每一次采樣數(shù)據(jù)相同的觸摸屏，都有漂移這個問題，目前有漂移現(xiàn)象的只有電容觸摸屏。

Control technology
The big feature of DCS in control is that it relies on the flexible configuration of various control and operation modules to achieve a variety of control strategies to meet the needs of different situations, which makes the rather cumbersome and complex propositions realized in the unit combination instrument simple. With the high flexibility and benefit requirements put forward by enterprises, the control scheme based on classical control theory can no longer adapt to it. After the control strategy represented by multivariable predictive control is proposed and successfully applied, process control has been widely concerned by process industry. It should be emphasized that the wide application of various control and optimization technologies is an effective, direct and valuable development direction for mining and improving the comprehensive performance of DCS.

coordinate
The touch screen is a coordinate system, where you want to choose to directly point that, and the essential difference between a relative positioning system such as the mouse is the intuition-in-place, the characteristics of the coordinate system is that each positioning coordinate has no relationship with the last positioning coordinate, the touch screen is physically a set of vertical coordinate positioning system, each touch data is converted to the coordinates on the screen through calibration data, so that, It is required that the set of coordinates of the touch screen in any case, the output data of the same point is stable, if it is unstable, then the touch screen can not coordinate positioning, the point is not correct, which is the problem of the touch screen: drift. In principle, any touch screen that cannot touch the same sampling data at the same point every time has the problem of drift, and at present, only capacitive touch screen has drift phenomenon.
