一種采用自動校正的ups蓄電池組巡檢系統的設計

摘要：介紹一種采用普通數字光耦實現了蓄電池組的每一節單體電池電壓的無源耦合，利用軟件二次曲線補償的方法解決了因普通數字光耦的信號耦合引起的非線性問題，利用線性光耦對電池組整體電壓進行采樣，可以計算出電池每伏電壓的補償量，從而解決了普通數字光耦的溫度漂移，為實際工程應用提供了一種可行的方案。 敘詞：數字光耦 線性光耦 二次曲線補補 溫度漂移 自動定標 Abstract： Introduce a scheme of solveing the temperature drift of ordinary digital optocoupler ,The process as follows.Adopting ordinary digital optocoupler achieves passive coupling about the voltage of per haploid batteries which belongs to accumulator battery. The nonlinear signal coupling problem is solved by the conic compensation of software. The voltage of the battery bank is sampled by linear optocoupler. Through the upper steps, we can calculate the compensation rate of the per voltage,In order to solve a common digital optocoupler temperature drift ,The scheme provides the feasibility of actual projects.
