zero check and adjustment is a fundamental work of shipborne combat system, and is also the basis and prerequisite for weapon system to attack target precisely 摘要零位檢測與規(guī)正是作戰(zhàn)系統(tǒng)裝艦的基礎(chǔ)工作,也是武器系統(tǒng)準(zhǔn)確打擊目標(biāo)的前提和基礎(chǔ)。
Hardware framework of the system is based on isa buses of general pc or ipc, including 12 _ bit multiplying d / a conversion, time interrupt, pulse receiving, zero check and on-off and warning circuit 該系統(tǒng)硬件結(jié)構(gòu)是基于普通pc機(jī)或工控機(jī)的isa總線而開發(fā),其功能集12位dac轉(zhuǎn)換、定時中斷、脈沖接收、倍頻辨向計數(shù)、零點檢測及使能報警等于一體。
Second, as currently study of hot point, back ? emf, it will discuss the principle of the sub-position examination in detail . based on the principle, it put forward a kind of improving back-emf method of crossing-zero checking turns position . but this did n't resolve to the root problem that the speed scope is very narrow and it need an in expiation of speed error and so on . thus it put forward a new improvement method at next chapter 其次,就目前所研究的熱點??反電勢法,詳細(xì)討論了其轉(zhuǎn)子位置檢測的原理,在此基礎(chǔ)上提出了一種改進(jìn)的反電勢過零點檢測方法,其可直接從電機(jī)端部得出反電勢對地的電壓值,而不是通過電機(jī)中心點電壓來得到反電勢。
In view of the limitation of traditional method of aiming at stars and object calibration, taking weapon system calibration under the special environment encountered in some engineering project for example, analyzes innovative application of weapon system zero check and adjustment under specified environment, puts forward " line calibration method ", in order to provide reference for similar weapon system or combat system calibration 鑒于傳統(tǒng)瞄星方法和標(biāo)定物標(biāo)定方法的局限性,以在工程中遇到的特定環(huán)境下的武器系統(tǒng)標(biāo)定為例,分析了具體環(huán)境下武器系統(tǒng)零位檢測與規(guī)正的創(chuàng)新性運(yùn)用,提出了“線標(biāo)定法”,以為類似情形下的武器系統(tǒng)或作戰(zhàn)系統(tǒng)標(biāo)定提供借鑒。
