A Multi-source Shared Far-Short-Range Communication System

Abstract

The invention proposes a multi-source shared long-distance communication system, which comprises an embedded control unit (1), a multi-source signal transmission unit (2) and a signal transmission interface (3). The embedded control unit (1) is respectively connected with the multi-distance multi-frequency signal input unit and the signal transmission interface (3). The present invention integrates all vehicle-mounted 4G, WIFI, GPS and other antenna devices, so that they all receive and send data through the system, avoiding waste of hardware resources and signal interference between antennas of the same type.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a multi-source sharing long-short-range communication system. Background technique [0002] With the development of electronic technology and communication systems, various devices need to be connected to the Internet and the background systems of related manufacturers. However, the bus system needs to be equipped with electronic equipment such as vehicle monitoring, IC card reading equipment, LED indicator lights, and LCD display equipment. Each electronic equipment has its own unique external communication modules such as GPS, 3G, 4G, and WIFI. However, there is no unified external communication signal standard in the public transport system, and the manufacturers of each equipment set the mode and frequency of the communication signal according to the standards of their respective equipment, which leads to the configuration of a large number of communication ...

AI Technical Summary

Problems solved by technology

However, there is no unified external communication signal standard in the public transportation system, and the manufacturers of each equipment set the mode and frequency of the communication signal according to the standards of their respective equipment, which leads to the configuration of a large number of communication antennas in the bus, and among them The types of various communication antennas are repeated, thus causing mutual interference between the same antennas of different devices from different manufacturers and resulting in waste of hardware resources

[0003] In order to solve the above technical problems, the present invention proposes a multi-source shared long-range and short-range communication system. By integrating all vehicle-mounted 4G, WIFI, GPS and other antenna devices, they all receive and send data through the system in a unified manner, avoiding the need for hardware resources. waste and signal interference between antennas of the same type
