【摘要】：電磁式繼電器廣泛應(yīng)用于航空航天、通信傳輸、工業(yè)控制等領(lǐng)域當(dāng)中。作為控制器件,其性能及可靠性往往決定了其所在系統(tǒng)的可靠性。如果能夠依靠繼電器初態(tài)信息預(yù)測(cè)出其壽命,將有著重大意義。預(yù)測(cè)繼電器壽命需要建立其壽命與其參數(shù)關(guān)系的模型,這就需要一種精準(zhǔn)測(cè)量繼電器各類參數(shù)的檢測(cè)設(shè)備。論文研究了可為壽命預(yù)測(cè)模型提供數(shù)據(jù)支撐的電磁繼電器參數(shù)檢測(cè)系統(tǒng),論文的主要工作如下:(1)通過對(duì)電磁繼電器性能退化過程進(jìn)行研究,分析出電磁繼電器性能退化對(duì)繼電器各個(gè)參數(shù)的影響,并從這些參數(shù)中選擇典型的參數(shù)進(jìn)行檢測(cè),圍繞這些參數(shù)提出了本檢測(cè)設(shè)備的功能需求。(2)通過分析對(duì)系統(tǒng)的功能需求合理建立檢測(cè)系統(tǒng)的具體設(shè)計(jì)方案,根據(jù)該設(shè)計(jì)方案以工控機(jī)搭載高速數(shù)據(jù)采集卡為硬件核心,完成了實(shí)驗(yàn)設(shè)備硬件的搭建,以圖形化編程語言虛擬儀器開發(fā)平臺(tái)編寫了軟件系統(tǒng)。該系統(tǒng)操作簡(jiǎn)單,人機(jī)互動(dòng)友好。檢測(cè)設(shè)備根據(jù)高速數(shù)據(jù)采集卡所采集到的波形計(jì)算直流繼電器各個(gè)參數(shù),并將波形與參數(shù)自動(dòng)顯示,同時(shí)將參數(shù)儲(chǔ)存在工控機(jī)中。經(jīng)過實(shí)驗(yàn)驗(yàn)證,實(shí)驗(yàn)設(shè)備的硬件軟件系統(tǒng)可以正常工作,能夠按照實(shí)驗(yàn)要求采集數(shù)據(jù),計(jì)算儲(chǔ)存繼電器各個(gè)參數(shù)。(3)選擇具體的繼電器試品使用本系統(tǒng)進(jìn)行完全壽命實(shí)驗(yàn),并按照本系統(tǒng)程序的設(shè)定將繼電器試品的所有參數(shù)數(shù)據(jù)儲(chǔ)存在相應(yīng)的電子文檔中,并利用上述數(shù)據(jù)進(jìn)行數(shù)據(jù)處理和分析,發(fā)現(xiàn)了以下規(guī)律:接觸電阻有逐漸變大的趨勢(shì),吸合時(shí)間隨著動(dòng)作次數(shù)的增加有減小的趨勢(shì),時(shí)間常數(shù)在繼電器壽命后期有明顯增加的趨勢(shì),而超程時(shí)間隨著動(dòng)作次數(shù)增加有變短的趨勢(shì)。
[Abstract]:Electromagnetic relay is widely used in aerospace, communication transmission, industrial control and other fields. As a control device, its performance and reliability often determine the reliability of its system. If the relay initial state information can be relied on to predict its life, it will be of great significance. In order to predict the life of relay, it is necessary to establish a model of the relationship between its life and its parameters, which requires a kind of equipment for accurately measuring all kinds of parameters of relay. The main work of this paper is as follows: (1) through the study of the degradation process of the electromagnetic relay performance, the main work of this paper is as follows: (1) the electromagnetic relay parameter detection system which can provide data support for the life prediction model is presented in this paper. The influence of the degradation of electromagnetic relay performance on the parameters of relay is analyzed, and the typical parameters are selected from these parameters to detect. The functional requirements of the testing equipment are put forward around these parameters. (2) through analyzing the functional requirements of the system, the concrete design scheme of establishing the detection system is reasonably established. According to the design scheme, the industrial control computer is equipped with a high-speed data acquisition card as the hardware core. The hardware of the experiment equipment is built, and the software system is compiled by the graphical programming language virtual instrument development platform. The system is simple in operation and friendly in human-computer interaction. The testing equipment calculates the parameters of the DC relay according to the waveform collected by the high-speed data acquisition card, and automatically displays the waveforms and parameters, and stores the parameters in the industrial control computer at the same time. Through the experimental verification, the hardware and software system of the experimental equipment can work normally, can collect the data according to the experimental requirements, calculate and store the parameters of the relay. (3) choose the specific relay test material to carry on the full life experiment with this system. According to the system program, all the parameter data of the relay test are stored in the corresponding electronic documents, and the data processing and analysis are carried out by using the above data. The following rules are found: the contact resistance has the tendency of increasing gradually, and the contact resistance has the tendency of increasing gradually, and using the above data to process and analyze the data. The absorption time decreases with the increase of the action times, and the time constant increases obviously at the end of the relay life, while the overrun time decreases with the increase of the action times.
