Thermosetting powder coating of low - temperature curing type is a newly - developed powder coating which is used on the things that are not suitable for high - temperture baking . this type of powder coating opens up wider application by lowering curing temperature to 108 - 130 . it can be used for surface coatings on such things as flaw detectors , auto water tanks , springs , electrical appliances with coils , instruments , equipment with tin welding seams . it can also be used on the products made of aluminum and magnesium materials , glass , plastics and wood etc 低溫固化型粉末涂料是針對那些不宜高溫烘烤的產品,而最新研制的新品種,它不僅具備一般粉末涂料的特征,而且可以把固化溫度降低到108 - 130 ,從而拓寬了粉末涂料的應用領域;適用于擦傷機械、汽車水箱、發動機、彈簧、線圈電器、儀器儀表、錫焊條接縫設備、鉛鎂材質、玻璃、塑料、木材等制品的表面涂裝。

Following notebook computer being used broadly in field detectiong , peripheral which have usb interface are prepotent more and more . the ultrasonc flaw detector we ' re designing will be connect with notebook computer in field detection , so we elect usb interface to accomplish transmission between detector and pc . the article not only introduces basic knowledge about usb briefly and gives detailed develop process of usb peripheral and flow diagrams of usb controller , but also operating against our device ' s functions , gives develop process of device driver and important api function being used . in addition , an exclusive interface being used to control and display is designed 我們所設計的探傷儀外置盒在現場作業時是與筆記本電腦相連接的,因此選用usb接口來實現數據在探傷儀外置盒與pc機間的傳輸。這里簡單的介紹了有關usb接口的基礎知識,給出了探傷儀usb接口的詳細開發過程及usb控制器的程序流程圖,并且針對于本儀器要實現的功能,給出了pc機端的設備驅動程序開發過程及關鍵的api函數調用程序。此外這里還設計了一個專用的控制及顯示界面。

Some testing devices are of advanced ones , such as scanning electronic microscope , microfocus circular radioscope , water - immersed ultrasonic flaw detector , 3 - axis measuring machines , large - sized projector , etc . for the production of non - aero products , there are large - sized die - casting equipment , and nearly 100 pieces of specialized gear machine tools including worm - gear grinding machine , etc . it has some specialized production lines for piston , crankshaft , cylinder and housing , etc . , as well as 4 flexible production lines advanced at home for motorcycle engine , and a complete set of automatic inspection test eqiuipment for motorcycle engine 計算機輔助設計輔助加工技術正在普遍使用。在非航空產品生產方面有大型壓鑄設備殼型鑄造,包括鍋桿輪磨在內的輪專用機床100多臺,以及活塞曲軸汽缸殼體等專業化生產線。此外,還建成了具有國內領先水平的4條摩托車發動機柔性生產線,以及成套的摩托車發動機檢測設備,可進行測試數據分析,改進檢定測試方法等。

In the digital ultrasonic flaw detectors , backward - wave signal is sampled and changed through the highspeed a / d converter , and we ' ll get a large number of datas . because datas are not all be used to draw testing curve , they must be compacted . lt is necessary to compress so much datas , so data - compaction instrument must be designed and used . here introduces the principle of data - compaction instrument , and designs a exclusive instrument using isp which may change compression point and automatically provide 1024 consecutive addresses of outside data storage unit 在數字化超聲波探傷中,回波信號經高速a d采樣變換后,會得到大量的采集數據。但在探傷曲線的描繪中并不是用到所有數據,因此要對這些數據進行壓縮處理,這就需要用到數據壓縮器,這里介紹了一種應用在線可編程技術及器件實現對大量采樣數據進行快速壓縮的方法,并設計了一種新型的專用isp數據壓縮器,該壓縮器具有壓縮點數可調,可自動提供1024個連續的外部數據存儲單元的地址等特點。

For the purpose of ensuring the quality of our products , our company has invested 4 million rmb in building multi - purpose lab , and introducing almighty experiment machine , impulsion testing machine , ultrasonic digital thickness - testing device , full - automatic ultrasonic thickness - testing device , sclerometer , ultrasonic flaw detector , x - ray machine , magnetic particle flaw detector and other advanced quality inspecting devices 為了確保產品的質量,公司投資400多萬元建起了多功能實驗室,配備了機械式萬能試驗機沖擊試驗機超聲波數字測厚儀全自動超聲測厚儀里氏硬度計超聲波探傷儀x射線機磁粉探傷儀等先進的質量檢測設備。

Through program technique on line in combination with usb , the box of ultrasonic flaw detector being controlled and displayed by pc is designed , which not only improves device performance , reduces cost , makes device handy , but also caters for tendency to development of peripheral of pc 通過在線可編程技術及通用串行接口技術的結合應用,把探傷儀外置盒設計成基于pc機控制和顯示的儀器,既提高了儀器的性能,降低了成本,又方便了使用,迎合了pc機外圍接口設備的發展趨勢。
