fig. 2 is a flowchart of a communication satellite energy-saving control method in an embodiment.
Detailed Description
The energy-saving control method for the communication satellite in the embodiment can be applied to the system shown in fig. 1. The system shown in fig. 1 includes a communication satellite, a satellite signal receiving tower and a central control center, wherein the communication satellite operates in space, the satellite signal receiving tower and the central control center are disposed on the ground, the communication satellite is connected to the central control center through the satellite signal receiving tower, the communication satellite can transmit data to the central control center and also can receive data transmitted by the central control center, and the central control center can transmit a control command to the communication satellite to control the operation of the communication satellite.
In this embodiment, the energy-saving control method for a communication satellite may be executed by the central control center in fig. 1, or may be executed by a control unit provided in the communication satellite, and the energy-saving control method for a communication satellite executed by the central control center is described as an example. In this embodiment, referring to fig. 2, the method for controlling energy conservation of a communication satellite includes the following steps:
s1, acquiring a ground image shot by a communication satellite;
s2, determining characteristic information of a region where the communication satellite passes according to the ground image;
and S3, controlling an energy-saving working mode of the communication satellite according to the characteristic information.
In this embodiment, steps S1 to S3 may be performed within a short time calculated in seconds, that is, the time of the whole execution process of the energy-saving control method for a communication satellite is short, so that the whole execution process of the energy-saving control method for a communication satellite may be regarded as being performed in real time.
In this embodiment, the communication satellite is provided with a camera instrument facing the ground direction, and can shoot ground images on the ground above the ground through which the communication satellite runs. The ground may be land or sea. The camera is oriented in the same direction as an antenna on the communication satellite that communicates with the ground.
When the central control center performs step S1, that is, the step of acquiring the ground image captured by the communication satellite, the following steps may be performed:
s101, acquiring the width of a communication signal transmission main lobe of a communication satellite;
s102, generating shooting parameters; the shooting parameters can set the size of a shooting visual angle, and the size of the shooting visual angle is related to the width of a main lobe of communication signal emission;
s103, sending the shooting parameters to a communication satellite;
and S104, controlling the communication satellite to shoot the ground image according to the shooting parameters.
In step S101, the central control center may obtain the transmission main lobe width of the communication signal of the communication satellite by sending a query instruction to the communication satellite or querying a local database. Under the condition that the height of the communication satellite relative to the ground is not changed and the antenna direction of the communication satellite is not changed, the signal coverage of the communication satellite on the ground is determined by the main lobe width of the communication signal transmission of the communication satellite, and the signal coverage of the communication satellite on the ground can be inquired and determined through step S101.
In step S102, the central control center generates shooting parameters, wherein the shooting parameters can control parameters such as resolution, aperture, shutter, exposure, and focal length used by a shooting instrument of the communication satellite when shooting the ground image. The central control center can control the size of the angle of view of the ground image shot by the communication satellite by adjusting the size of the focal length therein, for example, the larger the focal length used is, the smaller the angle of view is, under the condition that other conditions are not changed. The central control center can also intercept the central part of the ground image originally output by the shooting instrument of the communication satellite, and control the view angle of the ground image shot by the communication satellite by controlling the area proportion of the central part in the original ground image, for example, under the condition that other conditions are unchanged, the view angle is smaller when the area proportion of the intercepted central part in the original ground image is larger.
Referring to fig. 1, the central control center transmits the photographing parameters to the communication satellite through the satellite signal receiving tower in step S103, and instructs the communication satellite to photograph the ground image according to the photographing parameters in step S104. The communication satellite shoots and obtains a ground image by using the focal distance set by the shooting parameters, or a part of the ground image is cut out from the center of the ground image obtained by primary shooting by using the cutting proportion set by the shooting parameters, and the ground image (or the part thereof) finally returned to the central control center by the communication satellite has the shooting view angle size related to the width of the main lobe of the communication signal emission.
By executing steps S101 to S104, the central control center can determine the size and position relationship between the terrestrial signal coverage area of the communication satellite and the terrestrial area included in the terrestrial image according to the relationship between the size of the shooting angle of view of the terrestrial image obtained by shooting with the communication satellite and the size of the communication signal emission main lobe width by using the geometrical optics principle, so as to calculate the terrestrial signal coverage area of the communication satellite according to the terrestrial area included in the terrestrial image, and the central control center determines the terrestrial signal coverage area of the communication satellite in the electronic map thereof to execute the subsequent steps.
Alternatively, when steps S101 to S104 are executed, the size of the shooting angle of view set by the shooting parameters in step S102 is related to the width of the main lobe of the communication signal transmission, so that the terrestrial signal coverage area of the communication satellite on the ground is overlapped with a larger part of the terrestrial area included in the terrestrial image, and in case of neglecting the signal side lobe and other factors, the terrestrial area included in the terrestrial image can be considered as the terrestrial signal coverage area of the communication satellite on the ground, thereby providing a theoretical basis for executing steps S2 to S3.
Since the ground area contained in the ground image is related to the signal coverage area of the communication satellite on the ground, even the ground area contained in the ground image is the same as the signal coverage area of the communication satellite on the ground, the ground image can be used for determining the signal coverage area of the communication satellite on the ground without analyzing the signal coverage area of the communication satellite on the ground, and the cost generated in the process of shooting and returning the ground image through the communication satellite is lower than the cost generated in the process of analyzing the signal coverage area of the communication satellite on the ground, so that the resource requirements of the steps S101-S104 on the communication satellite, the central control center and other equipment are low, the occupation of too many resources of the communication satellite and the central control center is avoided, and the influence of the energy-saving control process on the communication service is reduced.
When the central control center performs step S2, that is, the step of determining the characteristic information of the region through which the communication satellite passes according to the ground image, the central control center may specifically perform the following steps:
s201, carrying out image recognition on the ground image;
s202, determining the region position information of the region where the communication satellite passes according to the image recognition result;
and S203, inquiring the communication service operation information of the region where the communication satellite passes according to the region position information.
In step S201, the central control center may operate the first neural network, input the ground image into the first neural network, and perform feature recognition processing on the ground image by the first neural network. Wherein the first neural network may be an artificial intelligence model such as a trained CNN network. The first neural network performs feature recognition processing on the ground image to extract feature information included in the ground image, and in step S202, the position information of the region included in the ground image, that is, the region position information of the region through which the communication satellite passes can be determined by the feature information included in the ground image. Specifically, the region location information of the region through which the communication satellite passes may be represented by data such as longitude and latitude coordinates corresponding to the ground image center point.
In step S203, the central control center may determine the communication service operation information of the region according to the region location information of the region through which the communication satellite passes. For example, if the region location information indicates that the region where the communication satellite passes is an unmanned region such as an ocean, a desert, a tropical rainforest, or a south-pole continent, it may be directly determined that no communication service is running in the region where the communication satellite passes; if the area location information indicates that the area where the communication satellite passes is other areas, the central control center can inquire communication service operation information such as the base station distribution of the area, the current service load of each base station, the service demand of a communication user and the like from a communication service operator.
Before performing steps S201-S203, the central control center may train the first neural network. The central control center can acquire a large number of sample images of the same type as the ground images, mark position information (such as longitude and latitude coordinates of a central point of the sample images) of the sample images, take the sample images as input information of the first neural network, take the position information corresponding to the sample images as expected output information of the first neural network, and train the first neural network. The first neural network used in performing steps S201-S203 is a trained neural network.
When the central control center performs step S3, that is, the step of controlling the energy saving operation mode of the communication satellite according to the characteristic information, the central control center may specifically perform the following steps:
s301, determining the service demand of the region where the communication satellite passes according to the communication service operation information;
s302, when the service demand is smaller than a preset threshold value, the communication satellite is controlled to enter an energy-saving working mode in a first time period.
In step S301, the central control center may predict a service demand of an area through which the communication satellite passes according to communication service operation information, such as base station distribution of the area, current service load of each base station, and service demand of a communication user, which is queried from a communication service provider, where the service demand may be expressed as data such as data transmission amount and number of call paths.
In step S302, the central control center may preset a threshold, compare the service demand with the threshold, and if the service demand is smaller than the preset threshold, it may be determined that the service demand of the area where the communication satellite currently passes is too small, and the communication satellite operates over the area to provide communication service, which lacks value, and may control to enter the energy saving operating mode in the first time period in the future.
Specifically, when the central control center controls the communication satellite to enter the energy-saving working mode within the first time period, the central control center may control the communication satellite to weaken the transmission intensity of the communication signal, reduce the transmission range of the communication signal, and/or close part of the built-in equipment within the first time period, wherein the transmission intensity of the communication signal and/or the transmission range of the communication signal may be weakened by reducing the transmission power of the antenna on the communication satellite, and the part of the built-in equipment may be closed by closing unnecessary frequency bands on the communication satellite, so as to reduce the energy consumption of the communication satellite, so that the communication satellite enters the energy-saving state, which is beneficial for the communication satellite to reduce the power consumption requirements on the solar battery and the chemical battery.
In this embodiment, the first time period set in step S302 may be set according to the area of the ground image, and specifically, the length of the first time period is positively correlated to the area of the ground image, that is, the larger the area of the ground image is, the longer the length of the first time period is, that is, the longer the area of the ground image is, the longer the communication satellite is kept in the energy-saving operation mode is. Since the execution of steps S1-S2 can determine that the communication service demand of the region included in the ground image, that is, the region over which the communication satellite is passing, is low or even zero, the longer the time for the communication satellite to maintain the energy-saving operation mode while passing over the region included in the ground image, the higher the value of energy saving can be exerted, and by setting the length of the first time period to be positively correlated with the area of the ground image, the time period for the communication satellite to pass over the region included in the ground image can be made to be approximately the same as the time period for the communication satellite to pass over the region included in the ground image, and the value of energy saving of the communication satellite can be better exerted.
In this embodiment, the center control center may further perform the following steps:
s4, acquiring working state parameters of the communication satellite;
s5, inputting the ground image and the working state parameters into a second neural network;
s6, performing feature recognition processing on the ground image and the working state parameters by the second neural network;
and S7, controlling an energy-saving working mode of the communication satellite according to the identification result of the second neural network.
In step S4, the central control center queries the communication satellite, or the communication satellite reports the working state parameters of the current orbit number, the electromagnetic frequency used for communication, the current remaining capacity of the chemical battery, the current generated power of the solar battery, the current service load and the like to the central control center.
When step S5 is executed, the central control center may operate the second neural network, input the ground image and the working state parameters obtained in step S4 into the second neural network, and perform feature recognition processing on the ground image and the working state parameters by the second neural network. Before the ground image and the working state parameters are input into the second neural network, the ground image and the working state parameters can be spliced, so that the ground image and the working state parameters form a group of input data for being processed by the second neural network. Wherein the second neural network can be an artificial intelligence model such as a trained CNN network. In step S6, the second neural network carries out feature recognition processing on the data formed by splicing the ground image and the working state parameters, and feature information contained in the ground image and the working state parameters is extracted.
In step S7, the second neural network may directly indicate whether to control the communication satellite to enter the energy-saving operating mode through the output value, for example, indicate to control the communication satellite to enter the energy-saving operating mode through the output value "0", and indicate not to control the communication satellite to enter the energy-saving operating mode or control the communication satellite to exit the energy-saving operating mode through the output value "1".
By executing the steps S4 to S7, the second neural network can be used to identify the ground image and the working state parameter, and determine whether to control the communication satellite to enter the energy-saving working mode, where the second neural network can also determine whether to control the communication satellite to enter the energy-saving working mode by combining the working state parameter of the communication satellite with the geographical information feature included in the ground image, where an influence of the working state parameter of the communication satellite on determining whether to control the communication satellite to enter the energy-saving working mode may be embodied in that if the working state parameter of the communication satellite satisfies a certain condition (for example, the current orbit lacks other communication satellites to provide communication services, and an electromagnetic frequency channel used for communication is an emergency service channel, so that the communication satellite is not suitable for entering the energy-saving mode to exit the service, the current remaining electric quantity of the chemical battery is large and does not need to save energy, the current power generation power of the solar battery is high and does not need to save energy, and the current service load capacity is heavy and cannot enter the energy-saving mode, and even if the region corresponding to the ground image belongs to a region with low communication demand such as an unmanned region, the communication satellite does not need to enter the energy-saving working mode.
Before performing steps S4-S7, the central control center may train the second neural network. The central control center can obtain a large number of sample images of the same type as the ground images and a large number of sample parameters of the same type as the working state parameters, splice one sample image and one sample parameter into a group of input samples, mark the energy-saving working mode representation values corresponding to the input samples (for example, "0" represents that the communication satellite is controlled to enter the energy-saving working mode, and "1" represents that the communication satellite is not controlled to enter the energy-saving working mode), use the input samples as the input information of the second neural network, use the energy-saving working mode representation values corresponding to the input samples as the expected output information of the second neural network, and train the second neural network. The second neural network used in performing steps S4-S7 is a trained neural network.
The energy-saving control method for a communication satellite in the present embodiment may be implemented by writing a computer program for implementing the energy-saving control method for a communication satellite in the present embodiment, writing the computer program into a computer device or a storage medium, and executing the energy-saving control method for a communication satellite in the present embodiment when the computer program is read out and run, thereby achieving the same technical effects as the energy-saving control method for a communication satellite in the present embodiment.
