【摘要】：如今电刷镀技术普遍应用在生产修复中,同时对电刷镀电源的可靠性的要求也相应地提高。研制一种能够快速准确测试电刷镀电源的仪器不仅对电刷镀电源的发展起到促进作用,同时还能推动电刷镀技术的发展。传统的测试方法主要由专业测试人员使用独立仪器对电刷镀电源进行测试,这种测试方法耗时长、效率低,无法满足工业化自动测试的要求。如何在现场实现对电刷镀电源的高效测试是目前电源测试领域急需解决的问题。因此,本学位论文设计了DSD系列高频电刷镀电源测试仪,该测试仪能够对电刷镀电源高压和低压重要参数进行提取,为现场工作人员提供精度较高的检测结果,便于现场工作人员分析数据和维护电源,有效地提高维修效率。首先,根据DSD系列高频电刷镀电源的工作原理及电源测试基本方法设计了信号调理电路(包括高压参数、低压参数以及IGBT相关参数的信号调理电路)、人机接口电路和外围电路等,针对电源实际工作产生数据的特点,分模块地采集和显示数据。其次,利用单片机STC12C5616AD作为整个测试仪的核心控制器件,结合单片机的PCA硬件捕捉模式对脉冲频率进行测量,并且采用拉格朗日插值算法对纹波数据进行处理,有效提高了纹波幅度的测量精度。最后,为了验证测试仪的准确性及可靠性,达到使用测试仪与传统的人工测试相对比的目的,分别使用本测试仪和独立仪器对现场电源进行测试,对比其测试数据,对测试仪的硬件电路进行了调试和验证。实验结果表明,本测试仪硬件电路稳定可靠,能够快速得到精度较为理想的电源参数采样值,符合电源智能化测试的要求。通过验证,该测试仪充分考虑了现场测试的实际需要,使得电刷镀电源测试变得快捷简单、准确有效。
[Abstract]:Nowadays, brush plating technology is widely used in production and repair, and the reliability requirement of brush plating power supply is also raised accordingly. The development of an instrument which can test the power supply of brush plating quickly and accurately can not only promote the development of brush plating power supply, but also promote the development of brush plating technology. The traditional test method is mainly used by the professional tester to test the brush plating power supply. This test method is time-consuming and inefficient, and can not meet the requirements of industrial automatic testing. How to realize the efficient test of brush plating power is an urgent problem in the field of power supply testing. Therefore, this thesis designed DSD series high frequency brush plating power source tester, this tester can extract the important parameters of high voltage and low voltage of brush plating power supply, and provide high precision test results for field workers. Easy for site staff to analyze data and maintain power supply, effectively improve maintenance efficiency. Firstly, according to the working principle of DSD series high frequency brush plating power supply and the basic method of power supply test, the signal conditioning circuit (including high voltage parameters) is designed. The signal conditioning circuit of low-voltage parameters and IGBT parameters, man-machine interface circuit and peripheral circuit, etc., are used to collect and display data in modules according to the characteristics of actual operation of power supply. Secondly, the pulse frequency is measured by using MCU STC12C5616AD as the core controller of the whole tester, and the ripple data is processed by Lagrange interpolation algorithm. The precision of ripple amplitude measurement is improved effectively. Finally, in order to verify the accuracy and reliability of the tester and achieve the purpose of comparing the test instrument with the traditional manual test, the test instrument and the independent instrument are used to test the field power supply, and the test data are compared. The hardware circuit of the tester is debugged and verified. The experimental results show that the hardware circuit of the tester is stable and reliable, and the sampling value of the power supply parameters with relatively high precision can be obtained quickly, which accords with the requirement of intelligent test of power supply. The test results show that the testing instrument takes full account of the actual needs of the field test, and makes the test of brush plating power source quick, simple, accurate and effective.
