Abstract

The invention relates to a carrier rocket ground test-launch control system, and discloses a PLC (Programmable Logic Controller) and 1553B based portable equivalent device for a carrier rocket test-launch control system. The carrier rocket test-launch control system comprises a comprehensive circuit combination, a PLC combination and an equivalent device emulational terminal, wherein the comprehensive circuit combination is mainly used for isolating and conditioning a rocket-ground signal; the PLC combination is equipped with corresponding functional modules and used for completing functional simulation of an on-rocket power supply and distribution system and a time sequence system; and the equivalent device emulational terminal is mainly used for completing both communication simulation of a rocket-ground 1553B bus and monitoring control of the PLC. The PLC and 1553B based portable equivalent device solves the problems of a conventional equivalent device equipment system, such as complicated constitution, more intermediate adapter cables, poor portability and the like, and obtains the benefits of high system integration level, less adapter cables, good portability and the like.
