Abstract

The invention discloses a power supply module in an integrated modular avionics system, which comprises an RTC chip, a temperature chip, a memory and a main processor, and is characterized in that themain processor executes the following program steps: 1, initializing hardware resources; 2, updating the state data on the memory in real time when a request sent by a general processing module is not received, wherein the state data comprises clock data on an RTC chip, temperature information on the temperature chip, module in-place information on each slot position and fatigue time information;and 3, when a request sent by the general processing module is received, reading a related state from the memory according to the content of the request, and uploading the related state to the general processing module, or controlling the power supply enabling of each slot position. According to the invention, the functions of power supply health monitoring, fault management and the like are realized.

Description

technical field [0001] The invention belongs to the field of airborne computers in avionics systems, in particular to an onboard power supply module in an integrated modular avionics system (IMA) based on single-chip operation. The airborne power supply module realizes power supply health monitoring and fault management And other functions, improve the reliability of the airborne power module. Background technique [0002] With the rapid development of integrated modular avionics systems, avionics equipment tends to be complex and comprehensive. Therefore, the research and application of health management and fault detection technology for avionics equipment is becoming more and more important. [0003] However, for early IMA equipment, IMA equipment stays in the two stages of simple physical synthesis, physical synthesis and partial functional synthesis. IMA equipment requirements. The increasingly integrated and complex IMA technology has put forward new requirements for...
