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.

Description

technical field [0001] The invention relates to a launch vehicle ground measurement and launch control system, in particular to a portable launch vehicle measurement launch control system equivalent device based on PLC and 1553B. Background technique [0002] The equivalent device simulates the electrical system of the launch vehicle, completes the self-inspection test of the ground measurement, launch and control system, and ensures that the ground measurement, launch and control system works normally before docking with the rocket, including the coordination and reliability of the software and hardware. [0003] In the past, the composition of the equivalent equipment system was relatively large, figure 1 It is the system connection composition diagram of the equivalent device in the past. The system includes the first and second signal transfer boxes, the integrated circuit combination, the module transfer box, the VXI chassis, the equivalent device control computer, the ...
