A Portable Rocket Flight Timing Tester

Abstract

The invention relates to a portable rocket flight timing sequence tester, and belongs to the technical field of rocket timing sequence control. Three timers with different functions are integrated ina microcontroller in the timing sequence tester; the first timer is used for generating self-checking square waves, and is matched with a multiplexer to complete self checking of N paths of timing sequence detection channels; the second timer is used for capturing a flight timing sequence timing zero point and recording N paths of flight timing sequence nodes; the third timer is used for capturingand testing timing sequence pulse signals; the two kinds of timers are matched with an optical coupling isolation device, so that the flight timing sequence node and the timing sequence pulse width of each path of initiating explosive device can be obtained, and the test result is stored on a FLASH chip. According to the timing sequence tester disclosed by the invention, the flight timing sequence of the whole simulated flight stage can be directly tested from the butt joint end of the cable net on the rocket and the initiating explosive device, and the tester has the advantages of being small in size, light in weight, high in universality and the like.

Description

technical field [0001] The invention relates to a portable timing tester which is suitable for testing flight timing signals at a timing signal output terminal during the simulated flight stage of rocket electrical system testing, and belongs to the technical field of rocket timing control. Background technique [0002] The timing control system of the rocket plays a vital role in the entire flight phase of the rocket. The timing control system sends timing pulse signals according to the pre-booked timing nodes to complete the separation between stages, the ignition of the secondary engine, the separation of the head and body, and the ignition of the reverse thrust engine. Key actions such as hood throwing, load release, timing nodes and ignition pulse accuracy directly affect the accuracy of the rocket's completion of various key actions, and even affect the success or failure of the rocket mission. [0003] In the development and test stage, the table-top joint test of the...
