【摘要】：針對航空電纜檢測國內(nèi)大部分航空制造企業(yè)仍然沿用手工檢測、少部分國內(nèi)航空企業(yè)使用自動檢測設(shè)備但分辨率低下、國外自動檢測設(shè)備價格昂貴等問題,研制了航空電纜自動檢測系統(tǒng)。本系統(tǒng)能提高電纜檢測效率,可靠性,節(jié)省人力,減少人為錯誤,防止誤連接,實現(xiàn)電纜檢測智能化,快速修復(fù)損傷電纜。本系統(tǒng)實現(xiàn)了在不帶插座轉(zhuǎn)換模塊的情況下,可以測試所有128腳型號插頭的航空電纜。在帶插座轉(zhuǎn)換模塊的情況下,可以測試所有型號航空電纜。本系統(tǒng)具有自檢功能、清零和校準(zhǔn)功能、電纜庫功能。如果被測電纜還沒有添加到電纜庫中,用戶可以選擇全自動檢測,全自動檢測會逐點掃描一個點與另外所有點的連接情況。如果被測電纜已經(jīng)添加到電纜庫中,用戶可以選擇快速檢測,快速檢測根據(jù)電纜庫中該電纜的指標(biāo)要求,只對要求檢測的管腳進行點對點測量。本系統(tǒng)為了保障系統(tǒng)內(nèi)部電阻不引起測量誤差,對前面板插座的每個管腳進行內(nèi)阻測量,存入內(nèi)阻庫,測試電纜時減去相應(yīng)的內(nèi)阻。用戶可定時對內(nèi)阻庫進行校準(zhǔn)更新。為了避免相同電纜再次測試時還要進行錄入電纜操作,應(yīng)建立了電纜庫,提高了測試效率。用戶可以自行增加、修改、刪除被測電纜。本系統(tǒng)在硬件方面采用高精度萬用表板卡,繼電器矩陣板卡來實現(xiàn)功能。采用繼電器矩陣控制多芯電纜實現(xiàn)自動檢測。軟件由采用美國國家儀器(NI)公司機構(gòu)的CVI9.0編程軟件來編寫。航空電纜自動檢測系統(tǒng)可節(jié)省了一半以上人力。與人工檢測相比,快速檢測大約可節(jié)省十分之九的時間;全自動檢測大約可節(jié)省十分之五的時間。能提高了準(zhǔn)確度,能時快速顯示電纜阻值及定位故障,提高企業(yè)電纜檢測效率。
[Abstract]:To solve the problem that most domestic aviation manufacturing enterprises still use manual inspection, a small number of domestic aviation enterprises use automatic detection equipment but the resolution is low, and the price of foreign automatic detection equipment is expensive, etc. This system can improve the efficiency and reliability of cable detection, save manpower, reduce human error, prevent wrong connection, and realize intelligent cable detection. Fast repair of damaged cable. This system can test all 128 pin plug cable without socket conversion module. In the case of socket conversion module, Can test all types of aerial cable. This system has self-checking function, zero checking and calibration function, cable library function. If the cable under test has not been added to the cable library, the user can choose automatic detection, Automatic detection scans the connection of one point to all other points point by point. If the cable under test has been added to the cable library, the user can choose to quickly detect the cable according to the requirements of the cable in the cable library. In order to ensure that the internal resistance of the system does not cause measurement error, the internal resistance of each pin of the front panel socket is measured and stored in the internal resistance storehouse. When testing the cable, subtract the corresponding internal resistance. The user can calibrate and update the internal resistance library regularly. In order to avoid the input cable operation when the same cable is tested again, the cable bank should be established. The test efficiency is improved. The user can add, modify and delete the tested cable by himself. The system adopts high precision multimeter board card in hardware. Relay matrix board card to achieve the function. Using relay matrix control multi-core cable automatic detection. The software is compiled by using the CVI9.0 program software of the national instrument company. The aeronautical cable automatic detection system can be used. More than half of the manpower saved. Compared with manual testing, Fast detection can save about 9/10 time, automatic detection can save about 5/10 time. It can improve accuracy, quickly display cable resistance and locate faults, and improve the efficiency of cable detection in enterprises.
