Problems solved by technology
[0002] At present, the commonly used method for measuring the action time of electric igniters is the target line method, which requires the testing personnel to have sufficient experience to complete, otherwise due to the degree of tightness of the winding of the fuse, the location of the binding, the selection of the fuse or the action of the electric igniter. Factors such as the impact of the residue on the quality of the next wiring will cause data distortion
In addition, the method is cumbersome, time-consuming and labor-intensive

The invention discloses an action time testing system for an electric igniter, and the system comprises a photoelectric coupler, optical fibers, photoelectric detectors, a signal processor, an FPGA data processing circuit, and an LCD. An ignition head of the electric igniter is in series connection with one photoelectric coupler, and two to-be-tested points of the igniter are provided with two optical fibers. The two optical fibers are respectively connected with one photoelectric detector. The photoelectric coupler and the photoelectric detectors are connected to the signal processor, and then a time value is disposed on the LCD through the FPGA data processing circuit. The system employs the optical fibers to serve as a sensor, employs the FPGA to carry out signal processing, improves the testing precision, is resistant to electromagnetic interference, is high in sensitivity, is high in testing precision, is low in cost, and is simple in operation.
Description
technical field [0001] The invention relates to a test system for the action time of an electric igniter, which belongs to the technical field of photoelectric information. Background technique [0002] At present, the commonly used method for measuring the action time of electric igniters is the target line method, which requires the testing personnel to have sufficient experience to complete, otherwise due to the degree of tightness of the winding of the fuse, the location of the binding, the selection of the fuse or the action of the electric igniter. Factors such as the impact of the residue on the quality of the next connection will cause data distortion. In addition, the method is cumbersome, time-consuming and labor-intensive. Contents of the invention [0003] Purpose: In order to overcome the deficiencies in the prior art, the present invention provides a test system for the action time of an electric igniter. [0004] Technical solution: In order to solve the a...
