Abstract

The invention discloses an ignition time measuring system of an electric ignition head. The system comprises a timer, an ignition power supply and an ignition time measuring component; the ignition time measuring component includes a hidden box, and a photoelectric sensor, a Fresnel lens and a bracket mounted in the hidden box; the electric ignition head connected with the ignition power supply is put on the bracket; the photoelectric sensor is positioned near a focal position of the Fresnel lens, and is connected with the timer; and the electric ignition head is positioned on one side opposite to a focus of the Fresnel lens, and is arranged near the optical axis of the Fresnel lens. The system has such advantages as simple structure, low manufacturing cost, convenience for operation, high measuring precision and sensitivity and accurate and reliable measuring result.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to an ignition time measuring system of an electric ignition head. Background technique [0002] Electric igniter is a general-purpose igniter, widely used in pyrotechnics, civil blasting and other related industries. The ignition time of the electric ignition head refers to the time interval from when the electric ignition head is energized to when it is triggered. This parameter is a key performance parameter of the electric ignition head. The electronic ignition heads used in fireworks display, stage fireworks special effects and dramatic pyrotechnics have very strict requirements on the main performance of electronic ignition heads - ignition time. In the current international standard of the electric ignition head, the measurement accuracy of the delay time of the electronic ignition head is required to reach 0.01 millisecond. At present, there is no report on the mea...
