Miniaturized and high-reliability test launch control system based on PowerPC and working method

Abstract

The invention discloses a miniaturized and high-reliability test launch control system based on a PowerPC. The system is characterized in that: a video format conversion control module is used for receiving display information of a processor and sending the display information to a display; a switching value control module is used for sending collected internal state quantities of an unmanned aerial vehicle and a test launch control system to the processor and transmitting power distribution and time sequence control signals sent by the processor to the unmanned aerial vehicle; a UART controller is used for sending RS422 communication content to the processor and transmitting a test sending instruction sent by the processor to the unmanned aerial vehicle; an AD acquisition control module is used for transmitting analog quantity data in the unmanned aerial vehicle and the test launch control system to the processor, and the processor is further used for performing health diagnosis according to the received analog quantity data and judging whether to send an alarm signal to test launch control remote control equipment; and a CAN controller is used for transmitting CAN communication content sent by a programmable power supply to the processor, analyzing a CAN communication control instruction transmitted by the processor and sending the CAN communication control instruction to the programmable power supply. The miniaturized and high-reliability test launch control system realizes light weight and miniaturization.
