Modular design is adopted in digital modulation system . in this way digital modulation system consist of vedio process module , synchronized drive module , semiconductor laser modulation and system control module 數(shù)字化調(diào)制系統(tǒng)采用模塊化設(shè)計(jì)方法,把系統(tǒng)分為四個(gè)功能模塊,即視頻信號(hào)處理、同步驅(qū)動(dòng)、半導(dǎo)體激光調(diào)制和系統(tǒng)控制模塊。
Synchronized drive module produces horizontal drive signal in synchronization with horizontal synchronization signal and field drive sawtooth in synchronization with vertical synchronization signal . these signal drive scaning sytem of slltv 同步驅(qū)動(dòng)模塊產(chǎn)生與行、場(chǎng)同步的行同步驅(qū)動(dòng)信號(hào)和場(chǎng)鋸齒波驅(qū)動(dòng)信號(hào),用于驅(qū)動(dòng)激光電視的掃描系統(tǒng)。
In order to improve the dynamic and static performances , and to increase the load ability of the system , the problem of synchronized drive of multiple motors must be taken seriously , thus , the synchronized control of multiple motors is very important 為了提高多電機(jī)傳動(dòng)系統(tǒng)的動(dòng)態(tài)和穩(wěn)態(tài)性能,以及滿足一些特定系統(tǒng)對(duì)于多電機(jī)精確同步的要求,多電機(jī)同步控制方法的研究也變得越來越重要。
It can be used to grind straight line fiat edge , pencil edge , og edge , etc . it adopts synchronized belts two belts , two side holding and synchronized drive to transmit glass , the upper belt can be adjusted vertically according to the glass thickness , two groups of spindles are distributed symmetncally , it can grind two sides at the same time , one of the two groups of spindles is fixed while the other can move horizontally , spindles adjustment can be made in three directions vertical rise and fall , horizontal forward and backward 可用于磨削直線平邊圓邊og邊等采用同步皮帶雙帶雙側(cè)夾持同步驅(qū)動(dòng)傳送玻璃。上帶可根據(jù)加工玻璃厚薄作上下調(diào)整,兩組唐頭對(duì)稱分布,平行雙邊同時(shí)磨削,兩組磨頭其中一組固定。另一組相對(duì)可作平行移動(dòng),磨頭調(diào)整有三種運(yùn)動(dòng)垂直升降水平進(jìn)退以及翻轉(zhuǎn)。
