Description

technical field [0001] The invention relates to the field of ship network communication, in particular to a ship network multi-channel Beidou communication gateway system. Background technique [0002] The real-time monitoring of ship navigation information in the ship network is an important guarantee for safe navigation of ships. With the increase of types of ship-borne sensors and smart devices, the data lacks effective integration, and valuable data is difficult to transmit to the staff in time, which affects navigation safety; Shipborne instruments responsible for sensing and broadcasting ship navigation information are often limited by factors such as the working frequency band and antenna height, and the communication distance is limited, which makes the monitoring system have blind spots, which cannot well meet the real-time monitoring needs of the shore-based dispatching center for ocean-going ships. . As a global satellite positioning and communication system inde...

Problems solved by technology

However, there are many types of onboard sensors and smart devices, and the data is cumbersome, making it difficult to effectively use the Beidou communication bandwidth.

[0003] The serial channel and processing capacity of a single single-chip microcomputer are limited. With the increase of on-board sensors and the increase in the amount of communication data, it is difficult for the single-chip microcomputer to achieve efficient data processing, and it is difficult to ensure the system operation in the wet and strong electromagnetic interference sailing environment of the ship. reliability and stability

Commonly used serial port expansion methods mainly include software simulation and parallel port expansion serial port. The software simulation method can use the timer and the I / O port of the host computer to simulate the timing of serial communication according to the transmission format of serial communication, so as to achieve the purpose of extending the serial port. The purpose of this method is that it takes up less system resources, is low in cost, and is easy to implement, but its sampling times are low, the accuracy of the data is difficult to guarantee, it cannot simulate too high a baud rate, and it will take up more software resources; the parallel port The function of the extended serial port method is relatively powerful, it can provide communication control signals, and the communication speed is high, but the control is complicated, it takes up more port resources of the MCU, and the price is also higher
