摘要： A spark detector indicates the presence of a spark by analyzing sound waves generated when an electrical spark is produced from an electrical spark generator located on an igniter rod. The spark detector includes an acoustic sensor that is in communication with the igniter rod to determine the time for the spark sound wave to travel through the igniter rod to the acoustic sensor. If a spark is not detected, the spark detector may output a signal indicating at least one of (i) the spark was not detected, (ii) to replace the electrical spark generator immediately, or (iii) replace the electrical spark generator soon such as at the next scheduled maintenance. Furthermore, the spark detector may be calibrated based on current temperature of the igniter rod based upon time of propagation of a pulse sound wave, generated by a pulse-echo generator, to reflect off an end of the igniter rod.
摘要翻译： 火花探测器通过分析当位于点火器杆上的电火花发生器产生电火花时产生的声波来指示火花的存在。 火花探测器包括声学传感器，其与点火器杆连通以确定火花声波穿过点火器杆行进到声学传感器的时间。 如果未检测到火花，则火花检测器可以输出指示（i）未检测到火花，（ii）立即更换电火花发生器，或（iii）立即更换电火花发生器中的至少一个的信号 就像在下一次计划维护一样。 此外，基于由脉冲回波发生器产生的脉冲声波的传播时间来基于当前点火器杆的温度来校准火花检测器以反射离开点火器杆的端部。
