Abstract

The monitoring device includes multiple channels in radio frequency, power supply management circuit, interface circuit and centralized setup processing module. The power supply management circuit is in use for supplying power, toggling power switch, and testing input current. The interface circuit provides interfaces of power supply, communication and radio frequency signal for all channels to connect with upper layer. The processing module includes parts: correction control unit for controlling data correction of all channel; protection control unit in use for carrying out real time calculation and process locally based on tested data in order to generate control command for protecting channels; communication unit in use for transferring notification and command to up layer system. Further, real time calibration for each channel circuit can be completed locally. Under condition of ensuring reliability, rapidity and maintainability are raised, and cost is lowered.

Description

technical field [0001] The invention relates to a monitoring device for realizing a radio frequency transceiver end of a wireless communication system, in particular to a real-time centralized monitoring device for a time division duplex (TDD) system radio frequency transceiver end. Background technique [0002] The real-time monitoring device at the RF transceiver end of the TDD system is the data acquisition, control and communication core of the RF part of the entire outdoor base station communication system. It is used in the TDD wireless communication system to perform multi-channel two-way transceiver monitoring on the wireless signals transmitted by the base stations in the system. [0003] The development of modern communication technology requires that the capacity of a single base station can be larger, so more radio frequency channels need to be added, and base stations with four channels or more have greater market potential. At the same time, the maintenance wo...
