Embodiment Construction
[0013] The invention adds a built-in U-disk to the airborne cable, and stores system initial configuration scheme files in the U-disk. The system integrated processor defines the cables of all connected devices by reading the configuration scheme file on the U disk, and completes some system initialization work, so that the system can be converted from hardware configuration to software configuration. Moreover, the U disk is built into the installation cable, and the system redundant equipment and system processor can be loaded and unloaded completely independently of the aircraft, thereby improving the maintainability and expandability of the system. Because the use of the storage device of the current USB interface is very mature and reliable, the cost is low.
[0014] First of all, the solution requires a built-in U disk to be solidified on the installation cable, which is only used as the slave disk of the onboard integrated processor, and the interface connection of the U...

The invention provides an automatic identifying and configuring method for an airborne multi-redundancy device of a general-purpose plane. The method comprises the steps of: solidifying a built-in USB (Universal Serial Bus) flash disk on an installing cable as a Slave disk of an airborne comprehensive processor, wherein system configuration documents are stored in the built-in USB flash disk; defining an interface connecting line of the built-in USB flash disk on an airborne cable interface of the airborne comprehensive processor; executing process of automatically identifying process: electrifying the airborne comprehensive processor; reading the system configuration documents stored in the built-in USB flash disk; according to the system configuration documents, defining all cables connected with the device by the airborne comprehensive processor, and configuring the device interface on software and initializing the system; and identifying the airborne redundancy device. The method provided by the invention cannot only complete configuration information required by system initialization, but also defines connection of each cable, so that the airborne device is agilely defined, the maintainability and expandability of the system are improved, and the production cost is lowered.
Description
technical field [0001] The invention relates to a method for identifying and configuring airborne multi-redundant equipment. Background technique [0002] Adding onboard redundant equipment to eliminate or reduce the impact of faults on the entire airborne system is a general method to improve the reliability of the airborne system. Usually, the identification of multi-redundant equipment on board is defined separately through the cables or buses connected to the equipment so as to achieve the purpose of distinction. This method requires the use of different cables to connect equipment with exactly the same software and hardware. Taking dual-redundancy equipment as an example, two wiring tables are required for the cables of airborne equipment, and two different cables are made, which increases the production cost and reduces the maintainability and scalability of the system. Contents of the invention [0003] The invention provides an automatic identification and configu...
