Abstract

The invention discloses a multi-channel bus data simulation system to help development or test personnel achieve zero encoding and common bus different information formulas rapidly. According to the technical scheme, multi-channel bus data simulation software operating at a computer terminal assembles information and messages according to a bus formula and data, a data packaging module pushes the data to a data sending queue management module to be sent, and a data analysis module calls Ethernet TCP drive according to bus configuration information and sends sending queue data to corresponding bus data bus engines corresponding to bus Ethernet. An engineering management module calls a data storage engine to achieve data reading and writing and pushes the received bus data to a receiving data cache. A receiving data management module calls a simulation configuration information management module to return analysis formulas and transmit to a data analysis module after receiving notices. The data analysis module calls a data type conversion module to achieve data receiving and analysis.

Description

technical field [0001] The present invention relates to a device simulation process based on bus communication, which is mainly used for various bus protocol data including multiple buses, Ethernet, MIL-STD-1553B bus, CAN bus, RS232 bus, RS422 bus and RS485 bus Simulation System. Background technique [0002] With the rapid development of modern computer technology and testing technology, computer simulation is used in the design of electronic integrated systems to simulate or analyze the communication data of multiple buses of electronic equipment to form a matching and testing environment for software development, which is very important for improving the system. Design efficiency and quality are of great significance. With the help of protocol management and message format management of configuration management in the simulation system, each team in the system development can uniformly control the bus protocol and message format; with the help of simulation and analysis ...
