In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a block diagram of a power control apparatus applied to a communication apparatus, the communication apparatus includes a signal output apparatus 11, and the power control apparatus includes an adjustment module 12 and a control module 13;
the output end of the signal output device 11 is connected with the input end of the adjusting module 12, the output end of the adjusting module 12 is the output end of the power control module 13, and the output end of the control module 13 is connected with the control end of the adjusting module 12;
the control module 13 is configured to generate a control signal according to the target output power and the actual output power;
the adjusting module 12 is configured to adjust an amplification factor of itself according to the control signal to amplify the power of the communication signal output by the signal output device 11, so that the actual output power of the power output device is stabilized at the target output power.
Big dipper localization tracking is widely used on civil aircraft, and the control accuracy of the transmitting power of the short message system of the aircraft is very critical, and the power control of the current short message transmitting channel mainly uses the power amplification factor of the fixed amplification factor to amplify the power of the communication signal output by the signal output device 11, and is generally limited to the dynamic adjustment capability of the signal output device 11 of small signals. Specifically, the prior art has several disadvantages in controlling power: first, the power adjustment range of the communication signal of the signal output device 11 is limited, and when a long cable is required for installation, the power consumed by the cable is large, and the corresponding compensation capability is insufficient. Secondly, the signal output device 11 and the communication channel in the prior art lack a power detection feedback mechanism, and cannot realize closed-loop control. Thirdly, the linearity of the small-signal output device 11 is good, and the accurate control of the output power can be generally realized, but the non-linearity of the power amplifier in the corresponding epitaxial channel cannot realize the accuracy of the power output through the epitaxial channel.
In order to solve the technical problem, the design idea of the application is as follows: and taking the nonlinear factors in the epitaxial channel into consideration, and then adjusting the output power of the epitaxial channel in real time according to the actual output power output by the epitaxial channel.
Based on this, the power control device in the present application is provided with a control module 13 and an adjusting module 12, wherein the control module 13 generates a control signal according to the actual output power of the power control device and the target output power of the user, and then adjusts the amplification factor of the adjusting module 12 in real time based on the control signal, so that the power output by the power control device is stabilized at the target output power, thereby implementing the closed-loop control of the power control device. When a long cable is required to be installed, the amplification factor of the adjusting module 12 can be dynamically adjusted to realize dynamic compensation of the output power.
It should be noted that the target output power in the present application may be a target output power preset by a user, and may also be an ideal output power corresponding to a communication signal output by the signal output device 11 without considering loss, which is specifically limited herein.
It should be noted that the signal output device 11 in the present application can be, but is not limited to, a radio frequency chip.
Therefore, in the application, the amplification factor of the adjusting module 12 can be adjusted through the actual output power and the target output power, so that the output power of the power output device can be adjusted in a closed loop manner, the output power is stabilized at the target output power, and the output power of the communication signal can be accurately controlled.
