Problems solved by technology

[0004] The working parameters of the traditional self-test signal are pre-set, but during the operation of the system, the working status of the transmitting link and the receiving link changes in real time, and it is impossible to make the self-test signal adaptively adjust its own working parameters, which greatly reduces the The response speed of various real-time changes on the link cannot ensure the stability of the self-inspection signal and the quality of satellite services. Therefore, the present invention proposes a method and system for automatic regulation of the communication system self-inspection signal to solve the problems existing in the prior art. question

Embodiment 1

[0037] according to figure 1 , 2 As shown, this embodiment provides a communication system self-test signal automatic regulation method, including the following steps:

[0038] Step 1. Periodically obtain the current real gain value of the gain adjuster, the self-test signal, the power ratio of the uplink service signal and the current real transmit power of the power amplifier, check and judge whether the current self-test signal level value X is within the self-test signal Level calibration value X 0 ±R range, where X 0 is the level value of the initial calibration of the self-test signal, R is a constant, and the value range is defined according to the actual situation of the system;

[0039] where X 0 Obtained by the following formula

[0040] x 0 =P 0 +10log 10 P 初始自检信号 / P 初始上行业务信号 +G 0

[0041] where P 0 is the output power of the power amplifier initially set, P 初始自检信号 / P 初始上行业务信号 is the power ratio of the self-test signal and the uplink service signal in...

Embodiment 2

[0062] This embodiment provides a communication system self-test signal automatic control system, in order to monitor the reliability of satellite uplink and downlink services in real time, and the stability of the time delay of uplink and downlink equipment, the self-check signal flow of the communication system self-check link Orientation is:

[0063] 1. The sending terminal generates and outputs a self-test signal;

[0064] 2. After the self-test signal is frequency-converted by the up-converter and amplified by the power amplifier, a small amount of signal is coupled by the coupler and enters the receiving link;

[0065] 3. If the RF frequency of the self-inspection signal is inconsistent with the RF frequency of the downlink service signal, the frequency converter is used to change the RF frequency of the self-inspection signal to the RF frequency of the downlink service signal, and at the same time adjust the power of the self-inspection signal; if the self-inspection si...

Abstract

The invention discloses a communication system self-checking signal automatic regulation and control method and system, and a transmitting link, a receiving link, a receiving coupler, a transmitting coupler, a frequency converter and a gain adjustor. The transmitting link comprises a transmitting terminal, an up-converter and a power amplifier; the receiving link comprises a low noise amplifier, a down converter, a sampling terminal, a digital signal processing unit and a monitoring computer, the gain adjuster is used for adjusting the power of a self-checking signal, and the frequency converter is used for changing the radio frequency of the self-checking signal to the radio frequency of a downlink service signal; according to the invention, the working states of the transmitting link and the receiving link are monitored by using the self-checking link, and the self-checking signal level value can intelligently adapt to the real-time working states of the transmitting link and the receiving link through self-confidence signal level regulation and control combined with coarse adjustment and fine adjustment, so that the self-checking signal can be stably and correctly received, and the self-checking efficiency is improved. And meanwhile, the deterioration of the downlink service signal quality can be reduced.
