摘　　要：为了能够方便准确地测出电点火具点火时间,提出一种新的电点火具点火时间测试方法。利用光纤作为传感器,FPGA进行信号处理,提高了系统测试精度。对该系统进行模拟实验,并利用本系统与已有的测试系统对电点火具的点火时间进行对比测试。试验证明,系统具有抗电磁干扰、灵敏度高、测试精度高、成本低和操作简单等优点。In order to conveniently and accurately measure the electric igniter ignition time, a new method for measuring electric igniter ignition time was proposed.Using the fiber as the sensor and FPGA for signal pro- cessing,the measuring precision of the system is enhanced. Simulation experiment and comparison experiment with the existed measuring system for electric igniter ignition were performed. Test results proved that the sys- tem has the features of electromagnetic interference, high sensitivity, high precision, low cost, and simple oper- ation.
