Embodiment Construction

[0015] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] figure 1 Shown is a schematic diagram of the structure of the packet, figure 2 Shown is the flow chart of the design method of the time-sharing communication protocol of the missile-borne equipment, such as figure 1 as well as figure 2 As shown, the method for designing the time-sharing communication protocol of the missile-borne equipment of the present invention comprises:

[0017] Step 1: Divide the commands and feedback packets that need to be sent into four categories. The categories cover product health status monitoring (device fault query commands and fault feedback), product function realization and control (device work commands and work status feedback), memory status monitoring (device memory que...

Abstract

The invention discloses a missile-borne device time division communication protocol design method. The method comprises the steps of S1, dividing instructions and feedback data packets needing to be sent into four classes of data, wherein the classification covers product health condition monitoring, product function realization and control, memory condition monitoring and device information query; S2, designing system communication periods and time slice duration, determining the communication periods according to performance index demands of a system, and dividing each communication period into four time slices with equal duration; S3, designing communication opportunities of various instructions and feedback data packets; and S4, designing a time slice sequence of the four classes of instructions and feedback data packets.

Description

technical field [0001] The invention relates to communication technology, in particular to a method for designing a time-sharing communication protocol for missile-borne equipment. Background technique [0002] In the design of traditional 1553B bus and RS422 bus, there is only one packet of data for communication. All kinds of information occupy one data packet together, and resources are tight. At the same time, regardless of whether the system needs it or not, all kinds of data will be communicated throughout the process, wasting communication resources. As today's requirements for missile functions, performance, support, and testability are getting higher and higher, traditional protocol design methods are difficult to meet current use requirements. [0003] Therefore, a protocol design method based on the principle of time-sharing communication is proposed. Classify the communication data, covering equipment failure information (device failure query command and fault...
