Abstract

The invention provides an anti-interference self-adaptive trunk amplifier, an anti-interference self-adaptive trunk amplifier system and a signal processing system; wherein a downlink amplification link comprises a first variable attenuator, a power amplifier and an operational amplifier, and a downlink signal is output after sequentially passing through a first power divider, a first radio frequency switch, the downlink amplification link and a second radio frequency switch; the first power divider is electrically connected with the first detector; the first comparison circuit judges an output level of the first detector and a first reference level and outputs a result to a switch control signal, and the switch control signal controls the first radio frequency switch and the second radio frequency switch and feeds back the result to the control circuit; the control circuit adaptively sets a first reference level according to the strength of the base station beacon signal received by the first detector; and a control circuit controls the first variable attenuator and the switching control signal. According to the invention, the anti-interference function is realized; wherein the switch overturning caused by an uplink signal is avoided, and an automatic level control function is realized through cooperation of the uplink amplification link and the downlink amplification link.

Description

technical field [0001] The present invention relates to the communication field, in particular to an anti-jamming adaptive trunk amplifier and system, and more specifically, the present invention relates to an anti-jamming adaptive trunk amplifier, a signal processing system and an anti-jamming adaptive system in a hospital. Background technique [0002] As the core of medical clinical informatization, electronic medical records have been developed for 15 years, and mobile ward rounds and bedside care matched with electronic medical records have also become the most important wireless mobile applications in hospitals. In daily nursing work, nurses need to use PDA to view and execute doctor's orders, and perform three checks and seven pairs of work. Since nurses have been carrying out medical orders on the move, they have high requirements for the stability of the wireless network. The traditional WiFi wireless network coverage method adopts the multi-AP method, but this met...
