Device and method for realizing energy saving of miniature repeater

Abstract

The invention discloses a device and method for realizing the energy saving of a miniature repeater. The method comprises the following steps of: coupling an uplink signal of an input end of an uplink amplification link, and carrying out filtering treatment; carrying out graining and small-signal amplification processing on the filtered signal; detecting the power energy of the uplink signal after amplification processing, and generating and inputting a direct-current level of the power linear variation of the uplink signal; and comparing the direct-current level with a preset voltage threshold value, if determining that the generated direct-current level value is no greater than the preset voltage threshold value, controlling switches arranged between active components and power sources in the uplink amplification to disconnect the power sources of the active components, and if determining that the direct-current level value is greater than the preset voltage threshold value, controlling the switches to connect the power sources of the active components in the unlink amplification link module. According to the method, the energy saving efficiency of the miniature repeater can be improved.

Description

technical field [0001] The invention relates to the energy-saving technology of repeaters, in particular to a device and method for realizing energy-saving of miniature repeaters. Background technique [0002] The repeater is a radio transmission relay device in the communication network system. In the process of radio frequency signal transmission, the power of the radio frequency signal is enhanced to extend the coverage of the base station, and the coverage of the base station is supplemented to ensure the normal operation of the communication network system. run. [0003] figure 1 It is a structural schematic diagram of an existing miniature repeater. see figure 1 , the micro-repeater includes an outdoor donor antenna, a first duplexer, a downlink amplifying link module, an uplink amplifying link module, a second duplexer and an indoor retransmitting antenna, the first duplexer is connected to the outdoor donor antenna respectively , the downlink amplifying link modu...

Problems solved by technology

[0024] It can be seen from the above that the existing repeaters using energy-saving technology mainly realize the energy-saving efficiency of the repeater by controlling the power consumption of the final power amplifier circuit of the uplink amplification link. For other active components, when the mobile terminal is in an idle state , still in the working state, which increases the power consumption of the repeater and reduces the energy-saving efficiency of the repeater
