[0020] Figure 2 is a detailed block diagram of an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0021] Next, in combination with Figure 1 , Figure 2 the present invention will be further described.

[0022] Referring to Figure 1 and Figure 2, the typical architecture of the intelligent power supply control technology for the communication payload in this embodiment includes an intelligent power supply management module 1, a data routing module 6, a satellite resource management module 5, a digital baseband processing module 2, a microwave frequency conversion module 3, and a phased array antenna 4. The digital baseband processing module 2 includes digital baseband processing modules 2-1 to 2-N, the microwave frequency conversion module 3 includes microwave frequency conversion modules 3-1 to 3-N, and the phased array antenna 4 includes phased array antennas 4-1 to 4-N.

[0023] Among them, the basic functions of the phased array antennas 4-1 to 4-N are power amplification and transmission of wireless signals and electronically controlled beam pointing. Additionally, in the present invention, each single receiving or transmitting channel of the phased array antennas 4-1 to 4-N needs to be designed with two modes: standby mode and working mode. In the standby mode, except for the control function being powered on, all other functional modules are in a power-off state, and the power consumption in this mode is very low. In the working mode, all functional modules are normally powered on. The switching between the standby mode and the working mode is controlled by the intelligent power supply management module 1. The basic functions of the microwave frequency conversion modules 3-1 to 3-N are up and down frequency conversion of radio frequency signals and gain adjustment. Additionally, each single receiving or transmitting channel needs to be designed with two modes: standby mode and working mode. In the standby mode, except for the control function being powered on, all other functional modules are in a power-off state, and the power consumption in this mode is very low. In the working mode, all functional modules are normally powered on. The switching between the standby mode and the working mode is controlled by the intelligent power supply management module 1. The basic functions of the digital baseband processing modules 2-1 to 2-N are to convert analog signals into digital signals and perform modulation, demodulation, and decoding on the signals. Additionally, the digital baseband processing modules 2-1 to 2-N need to be designed with two modes: standby mode and working mode. In the standby mode, except for the control function being powered on, all other functional modules are in a power-off state, and the power consumption in this mode is very low. In the working mode, all functional modules are normally powered on. The switching between the standby mode and the working mode is controlled by the intelligent power supply management module 1.

[0024] The data routing module 6 realizes the routing and forwarding of data and works with long-term power-on.

[0025] The intelligent power supply management module 1 controls the working modes of the phased array antennas 4-1 to 4-N, the microwave frequency conversion modules 3-1 to 3-N, and the digital baseband processing modules 2-1 to 2-N in real time according to the satellite resource allocation and usage situation provided by the satellite resource management module 5. When resources are occupied, it is set to the working mode, and when resources are released, it is set to the standby mode.

[0026] The brief working principle of the present invention is as follows:

[0027] The digital baseband processing module 2, microwave frequency conversion module 3, and phased array antenna 4 are typical component architectures for processing and forwarding communication satellites and are also payload components with high power consumption in the satellite. The digital baseband processing module 2 completes the modulation and demodulation functions of baseband digital signals, the microwave frequency conversion module 3 completes the up and down frequency conversion functions of radio frequency signals, and the phased array antenna 4 completes the functions of wireless signal transmission and beamforming. Therefore, two modes, namely standby mode and working mode, are required for the three payloads of the digital baseband processing module 2, microwave frequency conversion module 3, and phased array antenna 4. The intelligent power supply management module 5 controls the modes of the digital baseband processing module 2, microwave frequency conversion module 3, and phased array antenna 4. According to the requirements of the top-level services provided by the satellite resource management module 5, it intelligently and automatically controls the working modes of the three devices, namely the digital baseband processing module 2, microwave frequency conversion module 3, and phased array antenna 4, to achieve the purpose of intelligent management of energy use and device use.
