| 由于本系統(tǒng)送樣動作不需要實時跟蹤，目標(biāo)恒定，只需取樣時保證精確傳送定位即可。伺服舵機由以下幾個部分組成：舵盤、減速齒輪組、位置反饋電位計、直流電機、控制電路板等。其工作過程是，每一種液體流出后移送定位信息進(jìn)入信號控制芯片，獲得直流偏置電壓后與基準(zhǔn)電壓比較，獲得電壓差后輸出，再將電壓差的正負(fù)輸出到電機驅(qū)動芯片，決定電機的正反轉(zhuǎn)。電機轉(zhuǎn)速一定，通過級聯(lián)減速齒輪帶動電位器旋轉(zhuǎn)，伺服舵機用PWM信號控制速度和轉(zhuǎn)角，從而達(dá)到易控制、精度高和速度快的目的。 |

| Because the sample transferring action of this system has no need to real time tracking, the target is consistent and only insure that sample can be transferred back to position only. The servo steering gear consists of the following parts: tiller, reducing gear set, position feedback potentiometer, DC electric generator, and control circuit. The working procedure are sending position information to signal control chip after every fluid flowed out, comparing to standard potential after obtaining DC skewing potential, outputting after obtaining voltage difference and outputting charge of voltage to motion ship to determine the rotation. The constant revolution of generator, rotation of potentiameter of connected reducing gear, and controlling speed and angle by PWM signal by servo steering gear, are designed to goal the easy control, high accuracy and high speed. |
