Communication protocol test driving data automatic generation modeling method and system

Abstract

The invention relates to a communication protocol test driving data automatic generation modeling method, and the method comprises the steps: analyzing a communication protocol, and determining a system connected with the communication protocol and a mutual relation between the systems; determining the composition of user-oriented application data of the system according to the system connected with the determined communication protocol; and establishing a communication protocol storage structure model according to the determined composition of the user-oriented application data of the systemand the mutual relationship between the systems. The invention also relates to a communication protocol test driving data automatic generation modeling system. According to the invention, test drivingdata can be automatically generated, manpower and resources are saved, and the full coverage of protocol testing is achieved.

Description

technical field [0001] The invention relates to a method and system for automatically generating modeling of communication protocol test drive data. Background technique [0002] Aerospace / aviation loads, weapons and equipment are generally composed of multiple systems, and the information exchange between each system requires the use of buses in their respective fields, such as I2C, SPI, RS232 / 422 / 485 / UART, MIL-STD-1553, CAN, ARINC429 Wait. The communication protocol builds data in accordance with the respective bus standards at the physical layer and data link layer, but at the application-oriented application layer, due to the vastly different working methods of system equipment, designers cannot follow a unified application when designing communication protocols at the application layer. Standards, but comprehensive consideration based on the needs of system information interaction. Testing this protocol without a standard format consumes a lot of manpower and resource...

Problems solved by technology

The communication protocol builds data in accordance with the respective bus standards at the physical layer and data link layer, but at the application-oriented application layer, due to the vastly different working methods of system equipment, designers cannot follow a unified application when designing communication protocols at the application layer. Standards, but comprehensive consideration according to the needs of system information interaction

Testing this protocol without a standard format consumes a lot of manpower and resources, and the test results obtained are not satisfactory, and the full coverage of the protocol test cannot be achieved.
