摘要
为提高合成试验的控制水平,笔者提出了一种数字化同步控制方法。该系统以单片机为核心,能自动根据用户设定的试验参数计算出电压源回路与延弧回路的投入时间常数,通过在线调整D/A转换器的输出来控制电压源回路及延弧回路的投入时刻,系统还具有自动调零和误差在线修正等功能,提高了控制精度。笔者给出了系统的硬件电路,并编写和调试了软件。试验表明,所提出的合成试验同步控制方法实时性好、精度高,能有效地保证合成试验的成功率。
In order to improve the reliability and accuracy of synthetic test, a digitized synchronous control method is presented. The system, taking the single chip processor as its core, can calculate automatically the operation time of voltage source circuit and prolong arc circuit according to the testing parameter set by users, and adjust the injecting time through adjusting the output of D/A converter on line. The system has such functions as automatic zero adjustment and on line error modification to improve the control accuracy. The hardware circuit is designed and the corresponding program is coded and debugged. The experimental result indicates that the digitized synchronous control method is of better real time and high precision, which ensure the success rate of synthetic test.
