Abstract

The present invention relates to a split elevator communication system based on TD network mode, which includes a master unit and a slave unit; the master unit includes a first antenna for receiving and sending TD network signals, a coupler, a first signal processing module, and a synchronization module, a first modem module, a first combiner and splitter, and a second antenna; the slave unit includes a third antenna, a second combiner and splitter, a second signal processing module, and a second modem module , and the fourth antenna. The split elevator communication system of the present invention adds a modulation and demodulation module for modulating and demodulating synchronous signals in the host unit and the slave unit, which not only realizes the signal synchronization control function, but also does not need to use expensive synchronization modules in the slave unit, greatly Reduced system cost.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a split elevator communication system based on TD network mode. Background technique [0002] People rely more and more on mobile communication networks, but indoor areas are always difficult for signal coverage. The population density of the city is high, and there are many high-rise buildings. There is often a phenomenon that there is no signal in the elevator. The elevator coverage system is born to solve the problem of elevator mobile network coverage. The elevator coverage system generally consists of a host unit and a follower unit, and the host unit is installed above the elevator machine room or shaft. The slave unit is installed on the elevator car, and the master unit and the slave unit transmit mobile communication network signals in space. When the elevator car is at the top, the car unit and the host unit adjust to reduce the system gain to en...
