Multi-serial-port navigation information simulation integrated system

Abstract

The invention relates to a multi-serial-port navigation information simulation integrated system, which is characterized in that hardware thereof includes a PC104 architectural computer, a monitoring display, an input device, an RS232 / RS485 asynchronous serial interface chip and an interface device. The monitoring display and the input device are connected with the PC104 architectural computer directly, the interface device is a drive card with eight serial ports and is connected with the PC104 architectural computer through the RS232 / RS485 asynchronous serial interface chip, the PC104 architectural computer realizes simulation of information of navigation equipment, a man-machine interaction interface is displayed in the monitoring display, and the interface device is connected with target equipment and can be provided with eight serial ports. The multi-serial-port navigation information simulation integrated system has the advantages of low dependence on hardware structure, low cost, high flexibility, convenience in carrying and use and reliable performance, and has the friendly man-machine interface.

Description

Technical field: [0001] The invention relates to a multi-channel navigation information simulation integration system, which belongs to the technical field of computer software. In particular, it relates to a multi-channel navigation information simulation integrated system designed for testing and maintaining various navigation equipment and integrated navigation display consoles. Through the simulation test of the signal, the device can be quickly detected and fault located. Background technique: [0002] The navigation system should provide the necessary navigation information for the safe navigation of the ship to ensure the correct and safe navigation of the ship. The navigation systems (or equipment) equipped on modern ships mainly include ship inertial navigation system, platform compass, Roland C receiver, Omega navigation receiver, Meridian satellite navigation receiver, Navigator Global Positioning System receiver (GPS receiver or GLONASS receiver). At the same ...

AI Technical Summary

Problems solved by technology

At present, there are many dedicated simulator products on the market, such as GPS receivers, etc. Using a dedicated real simulator corresponding to each navigation device is not only expensive, but also has a single function, and it is not conducive to joint testing of multiple devices, and it is relatively difficult to carry at the same time. Inconvenient and not conducive to daily routine testing and other situations
