Bypass control method for two-path bidirectional tower amplifier

Abstract

The invention relates to a bypass control method for a two-path bidirectional tower amplifier, which comprises the two-path bidirectional tower amplifier and is characterized in that: a receiving antenna and a transmitting antenna of the amplifier are respectively connected with a duplexer through a radio-frequency switch; the radio-frequency switch is controlled by an MCU of the amplifier; the MCU is connected with a failure detection unit circuit; and alarms processed by the MCU comprise an over-temperature alarm, a stationary wave alarm, an amplifier failure alarm, a low noise amplifier failure alarm, a power-fail alarm, a power failure alarm and an overpower alarm. Through the method, judgement of each failure of a monitoring equipment system can be checked without misjudgement and faulted and unbypassed phenomena; after equipment is bypassed and each failure recovers, the equipment is in normal working order; remote control and inquiry can be carried out; and the method has better market value.

Description

technical field [0001] The invention relates to a tower-mounted amplifier bypass control technology in the communication field, in particular to a bypass control method of a dual-way bidirectional tower-mounted amplifier. Background technique [0002] The main function of the tower mount amplifier is to enhance the signal strength and increase the coverage. Generally, only uplink signal amplification is supported, without compensation for signal fading caused by equipment introduction. When the system fails, the corresponding bypass switching loss is too large, which affects the effect of the original coverage area. Due to the incomplete mechanism of controlling the switching bypass, it is impossible to judge the failure of the tower top amplifier. If there is no bypass, the equipment cannot work normally without bypass, which will affect the coverage of the original network. The control bypass switching mechanism of the existing ordinary equipment is relatively simple, onl...

Generally, it only supports uplink signal amplification, and does not compensate for signal fading caused by equipment introduction. When the system fails, the corresponding bypass switching loss is too large, which affects the effect of the original coverage area.

Due to the incomplete mechanism for controlling switching bypass, it is impossible to judge the failure of the tower top amplifier. If there is no bypass, the equipment cannot work normally without bypass, which will affect the coverage of the original network.

The control bypass switching mechanism of the existing ordinary equipment is relatively simple, only the low noise amplifier failure, power failure, and power failure alarm, due to the lack of alarm conditions, when the equipment fails, it cannot bypass and report the alarm, resulting in equipment failure Unable to work, affecting the original communication system and affecting normal communication

Failure to maintain equipment in a timely or effective manner increases the difficulty of equipment and network construction
