Embodiment 1

[0050] As mentioned in the background technology, the existing 1553B bus message scheduling method cannot be applied to the 100Mbps high-speed 1553 bus network, resulting in low data transmission efficiency

[0051] In order to solve the above problems, this embodiment discloses a time-sharing scheduling method for bus messages, which is used to sequentially transmit messages to be sent on the bus, and the bus includes multiple nodes.

[0052]The time-sharing scheduling method provided in this embodiment adopts a time-triggered method for scheduling, where time-triggered means that all activities on the network are planned and scheduled as time progresses. Maintain a global time and rely on this time to schedule the synchronization process, so all communication in the system can be simplified into a schedule table, in which the signal definition, timing change and scheduling assignment are all done offline.

[0053] The method follows the steps below:

[0054] Step 1. Obtain ...

Embodiment 2

[0106] A bus message time-sharing scheduling system, the system includes a time-sharing scheduling processor, and the time-sharing scheduling processor is used to implement the bus message time-sharing scheduling method in Embodiment 1.

[0107] In this embodiment, a time-sharing scheduling system is provided, and the system is used to implement the scheduling method in the first embodiment.

[0108] Through the description of the above embodiments, those skilled in the art can clearly understand that the present invention can be realized by means of software plus necessary general-purpose hardware, and of course also by hardware, but in many cases the former is a better embodiment . Based on this understanding, the essence of the technical solution of the present invention or the part that contributes to the prior art can be embodied in the form of a software product, and the computer software product is stored in a readable storage medium, such as a floppy disk of a computer...

Abstract

The invention discloses a bus message time-sharing scheduling method and system, which adopts a time-triggered manner to schedule network services, maintains a global time, and relies on this time to schedule the synchronization process, so that all communications in the system can be simplified It is a scheduling table, in which the signal definition, timing change and scheduling assignment are all completed offline; the present invention designs a virtual link scheduling table and divides specific time slots for each virtual link for data transmission , improve the utilization rate of the bus bandwidth, compared with the previous method of scheduling according to the message, the actual use efficiency of the single function service is improved; secondly, the data transmission is carried out after setting the whole network time to be consistent, which further improves the efficiency of the data transmission.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a bus message time-sharing scheduling method and system. Background technique [0002] At present, the main bus standard in the field of aerospace is MIL-STD-1553 (1553B), and its full name is the time-division command-responsive multiplex data bus inside the aircraft. Because of its reliability, flexibility, and certainty, the U.S. military regards it as the interconnection communication standard for airborne equipment. [0003] In the past 30 years, the U.S. military has successfully applied MIL-STD-1553B to a variety of fighters, and successfully applied to other control fields, such as missile control, ship control, etc., in the weapons and maintenance systems of the navy and army Has begun to adopt 1553B bus. [0004] With the construction of national defense modernization and the upgrading of weapon systems, as the corresponding standard of the national military sta...
