System and method for simulating information of CAN (Controller Area Network) bus navigation equipment

Abstract

The invention relates to a system and method for simulating information of CAN (Controller Area Network) bus navigation equipment. A system hardware part comprises a PC104 framework computer, a monitoring display, input equipment, a CAN interface chip SJA1000 and an interface device, wherein the monitoring display and the input equipment are directly connected with the PC104 framework computer; the interface device is connected with the computer through the CAN interface chip SJA1000; two CAN communication interfaces are provided by using the CAN interface chip; software consists of a main control module, a display module, a configuration module, a communication module and an information generating module; the main control module is used for coordinating and controlling the other modules to work; the configuration module is used for providing setting of a transmission information format and an information prompting color; during transmission of information, the main control module is used for transmitting a command of an interactive interface to the information generating module; and the information generating module is used for generating corresponding information as required, and transmitting the information to the communication module for transmitting.

Description

Technical field: [0001] The invention relates to a system and method for information simulation of CAN bus navigation equipment. In particular, it relates to a CAN bus navigation equipment information simulation system designed for the testing and maintenance of a variety of navigation equipment. Through the simulation of the signal, the CAN network can be analyzed, which is convenient for non-technical personnel to quickly detect and locate the equipment. It belongs to the field of computer software technology. Background technique: [0002] CAN stands for Controller Area Network, which belongs to the category of industrial fieldbus. Compared with the general communication bus, CAN bus data communication has outstanding reliability, real-time and flexibility. Because of its good performance and unique design, the CAN bus has attracted more and more attention. The communication medium can be twisted pair, coaxial cable or optical fiber. The communication rate can reach 1MBPS...

AI Technical Summary

Problems solved by technology

However, this not only requires a higher price, but also is very unintuitive for the user of the device

The number of CAN bus extension frames is 29 bits. When writing frame numbers for information simulation, displacement operations are involved, which is also very inconvenient for users

In addition, on a large ship, there are many devices, and the use of an independent CAN analyzer is not conducive to system integration
