Embodiment Construction
[0024] In the embodiment of this application, the messages sent by the applications in each partition are received through the message sending interface provided by the middleware, wherein each message has a message number used to identify the delivery mechanism of the message, and then each message, according to the corresponding relationship between the message number of the message and the configured message number and the physical bus, determine the physical bus used when dispatching the message, and then use the determined physical bus to dispatch the message, further , read messages from each physical bus, analyze each read message to obtain the message number of the message, and for messages with the same message number, according to the corresponding relationship between the configured message number and the target application, The destination application corresponding to these messages is determined, and the destination application can receive these messages through th...

The invention relates to the field of the embedded technology, in particular to a message transferring method and device in a multi-partition operating system for solving the problems of complex configuration work and high testing cost of a middle area communication port in the prior art. The message transferring method, which is provided by the embodiment of the invention, in the multi-partitionoperating system comprises the following steps that: through a message sending interface provided by middleware, receiving a message sent from an application in each partition; for each message, according to a configured corresponding relationship between the message number and a physical bus, determining the physical bus used when the message is distributed, and using the physical bus to distribute the message; reading the message from each physical bus, and analyzing each read message to obtain the message number of the message; and for the message with the same message number, according tothe configured corresponding relationship between the message number and a destination application, determining the destination application corresponding to the message, and sending the message to thedestination application through the message receiving interface provided by the middleware.
Description
technical field [0001] The present application relates to the field of embedded technology, in particular to a method and device for message delivery in a multi-partition operating system. Background technique [0002] With the rapid development of Internet technology, the types of avionics software used in the aviation field are becoming more and more diverse. Since avionics software has relatively high requirements for safety and reliability, the security of the operating system that runs avionics software is also required. relatively high. [0003] At present, the ARINC653 operating system with relatively high security is mostly used to develop avionics software. Among them, the ARINC653 operating system can divide electronic equipment into multiple partitions, and run different applications in different partitions. The port provided by the operating system for communication. Since the ARINC653 operating system only provides basic interval communication ports, it is dif...
