Railway dispatching system wireless communication switching device and working method

Abstract

The invention relates to a railway dispatching system wireless communication switching device, which comprises a wireless cluster transfer wired interface, a 3G (The 3rd Generation Telecommunication) transfer wired interface, a GSM (Global System for Mobile Communications) transfer wired interface, a CDMA (Code Division Multiple Access) transfer wired interface, a control inversion module and a wired communication system, wherein the wireless cluster transfer wired interface, the 3G transfer wired interface, the GSM transfer wired interface and the CDMA transfer wired interface respectively receive corresponding signals and output the signals to an input end of the control conversion module; the control conversion module accesses the processed signals to the wired communication system through an output end; the control conversion module controls the wireless cluster transfer wired interface, the 3G transfer wired interface, the GSM transfer wired interface and the CDMA transfer wired interface. The railway dispatching system wireless communication switching device has the advantages that railway dispatching system wireless communication switching is realized, meanwhile the aims of joint management and coordination work of a dispatching system including wired users and wireless users are achieved, the connection time and speed are improved, the number of maintenance personnel is reduced, and the internal communication cost is almost zero.

Description

technical field [0001] The invention relates to a wireless communication switching device and a working method of a railway dispatching system. Background technique [0002] The traditional railway dispatching system is mainly based on wired communication, and it is usually assisted by wireless intercom. With the development of communication technology, wireless communication occupies an increasing proportion in the communication system due to its mobility and convenience. bigger. [0003] There are many existing mobile products and technologies, including traditional trunking intercom, advanced 3G communication technology, and widely used wireless communication technologies such as GSM and CDMA. These products are mature and widely used, but wired communication is still In an irreplaceable position, wireless communication and existing wired communication systems coexist in the railway dispatching system, resulting in serious waste of resources and low efficiency, which req...
