Power transformer test is simulanted in test - room, try to prove that online measure of transformer test is feasible. the test results are satisfaction. in the end, there is software design : the instrumented - test - interface is developed ; location computer entering to sample state is the same time, and after the same " log time ", it stops the data sample note. every test signal data keeping in the data note memorizer is at the same time, so it realizes data synchronization collection. some blocking design in the process of software design can apply to the other software
文章的最後，針對變壓器試驗微機測試系統對電流、電壓、功率等變量數據採集的特殊要求，分析了同步誤差的產生原因，給出了同步軟體采樣的無差條件；建立了電壓電流有效值和平均功率測量誤差的數學模型，提供了減小測量誤差的措施；應用「同步軟體采樣技術」 ，不需要增加采樣周期數，不需要硬體同步環節，較好地解決了同步誤差對測量精度的影響。That did not use double slope integral amplifier to realize equivalent sampling. in the course of testing the use of two methods designed to achieve equivalent sampling, the final selection of one of the best ways to be able to meet the demand of users results and performance indicators
該方案的優點是運用了大規模可編程邏輯器件fpga來實現隨機等效采樣而不是採用典型的基於雙斜率電容充放電的電路來實現的。在設計過程中試驗用兩種方法來實現等效采樣，最後選用了一種最好的方法，得到的結果能夠滿足用戶的要求和性能指標
