Problems solved by technology

On the one hand, if the background service center fails, it will directly lead to the paralysis of the entire system; on the other hand, if the connection mode of wired IP or E1 link is used, if the link is interrupted, the base station will form an isolated island, which will affect the normal operation of other base stations.

Abstract

The invention provides a distributed same-frequency simulcast signal transmission device and system, and relates to the field of mobile communication. According to the distributed same-frequency simulcast signal transmission device and system, communication signals sent by an intelligent terminal are received only through the communication unit of each base station; each base station obtains the signal strength of the received communication signals through a signal strength obtaining unit and issues the signal strength to the other base stations through the communication unit; each base compares the signal strength of own received communication signals with the signal strength sent the other base stations through a comparison unit, so that a master base station is determined; the master station issues received communication signals sent by the intelligent terminal to the multiple base stations and a receiving terminal. The master base station is unnecessarily selected by a cloud server. When one base station is damaged, the multiple base stations still can work normally. The phenomenon that the whole distributed same-frequency simulcast signal transmission system is paralyzed can be avoided. The reliability and stability of the distributed same-frequency simulcast signal transmission system can be improved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a distributed co-frequency and co-broadcast signal transmission device and system. Background technique [0002] Digital co-frequency and simulcast systems are often used as emergency communications. High reliability and high stability are important indicators for judging the quality of digital co-frequency and simulcast systems. At present, the digital co-frequency and co-broadcasting system is used to achieve large-area coverage of communication signals. Usually, multiple base stations are connected to the Internet with wired IP or E1 links, and the data source is judged and selected under the unified control of the background service center; the selected The base station uploads the voice to the switch and distributes the communication signal to each base station; finally, each participating base station controls the synchronous delivery of data and frequency lockin...
