Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
With the increasing popularity of civil and commercial use of satellites, the functional demands of the market for satellites have also changed greatly. For example, conventional satellites operate periodically around the earth, with each period being capable of communicating with ground stations only for a period of time, and full time coverage is not possible. Through networking among multiple satellites and centralized management and control of a ground station on a satellite network, the problem of coverage blind areas caused by periodic operation of the satellites can be solved, and all-weather satellite coverage is realized. The ground station can communicate with a certain satellite in the satellite network at any time, so that the communication with any satellite in the satellite network is indirectly realized.
In order to complete the above scheme, a necessary premise is to establish a satellite network. In the prior art, all satellites in a satellite network are typically almost "new satellites"; i.e. artificial satellites that are in orbit are deliberately launched for the networking needs. And undoubtedly, the large number of "new satellites" transmitted entails a significant cost.
In practice, however, a part of the "old satellites" that are currently already in orbit can also meet the basic requirements of the satellite network in terms of their own hardware. But not adapted at the software level, and therefore cannot be incorporated into the satellite network and cannot be invoked by the satellite network.
In view of this, the present invention provides a satellite invoking method. Referring to fig. 1, a specific embodiment of a satellite calling method provided by the present invention is shown. In this embodiment, the method includes:
step 101, determining a corresponding program package of the target satellite according to the type of the satellite-borne equipment of the target satellite.
The target satellite is an old satellite whose hardware condition can meet the basic requirement of the satellite network, and is also an object to be incorporated into the satellite network and further called by the satellite network. Under the current technical conditions, the hardware transformation of the old satellite can hardly be carried out, so the hardware condition of the old satellite can meet the requirement of a satellite network, and can meet the precondition of becoming a target satellite. The basic requirements of a satellite network for hardware conditions generally require that the processor on which the target satellite is mounted has sufficient computational power and that the memory on which it is mounted has sufficient memory space. In other words, the whole hardware architecture is required to meet a certain performance standard, and corresponding programs can be installed to complete software-defined or intelligent software layer transformation. At the same time, the target satellite should also typically have a specific on-board device. By controlling the on-board device, certain specific functions may be achieved. For example, the on-board device may include an optical camera, an infrared camera, and the like.
According to the type of the satellite-borne equipment of the target satellite, a corresponding program package of the target satellite can be determined. The package includes a series of software programs that need to be installed in the target satellite. The hardware condition of the target satellite meets the basic requirements of the satellite network, which means that it has a hardware basis for installing the series of software programs. After the installation of the series of software programs, the "software definition" or "intellectualization" of the target satellite is achieved. The program package may include: and operating a system program and a control program corresponding to the satellite-borne equipment of the target satellite. The control programs corresponding to the satellite-borne devices are different according to the types of the satellite-borne devices.
Step 102, the program package is sent to the target satellite, so that the target satellite installs the program package.
The package may be transmitted by the ground station to the target satellite. After receiving the package, the target satellite will install the package itself. Specifically, the operating system program may be installed in the target satellite first. Thereafter the target satellite may run the operating system program.
Various applications can be installed in the operating system program. The application is typically a control program for the on-board device. That is, after the target satellite has an operating system, the corresponding control program in the package may be installed under the operating system.
Step 103, establishing a virtual main body in the target satellite after installing the program package, and connecting the virtual main body to a satellite network.
After the target satellite has an operating system, a virtual body may be further established in an operating system program installed in the target satellite. The virtual body is similar to a virtual machine in the computer domain. I.e. a virtually existing satellite is established in the operating system. The virtually existing satellites also rely on the hardware of the target satellite itself and can also control the satellite-borne equipment of the target satellite.
It should be noted that the target satellite itself often has an inherent purpose. In order to not affect the inherent purpose and function of the satellite network after the satellite network is incorporated into the satellite network in the present embodiment, a virtual main body is selected to be established, that is, a "virtual satellite" is simulated in an operating system. It is believed that the satellite network will eventually incorporate a "virtual host", i.e., a "virtual satellite", into the satellite network. While the target satellite itself, the "subject" continues to perform its original function. The two are not interfered with each other.
Also, the virtual body has a virtual body identification such that it is equivalent to a "true satellite" and at the same time conforms to the communication standard prescribed by the satellite network. The virtual body identification may include information such as satellite name, satellite number, communication address, etc.
After the virtual body is established, the virtual body is further connected to the satellite network and incorporated into the satellite network. Because the virtual main body has the virtual main body identification and accords with the communication standard regulated by the satellite network, the virtual main body can be directly connected to the satellite network by utilizing the virtual main body identification so as to establish communication connection. A so-called satellite network typically includes a plurality of other satellites, as well as computing devices in ground stations. After the virtual principal connects to the satellite network, free communication with other principals (other satellites and computing devices) in the satellite network is enabled. At this time, the virtual body may be considered to be in a callable state, i.e., the satellite network may call the virtual body at any time to perform a specific operation.
Step 104, invoking a virtual main body in the target satellite through the satellite network.
After the virtual principal is connected to the satellite network and in a callable state, the virtual principal can be invoked through the satellite network, if necessary. I.e. invoking the virtual body to control the on-board device of the target satellite via the virtual body to perform the corresponding function. The virtual body may be part of a satellite network similar to other "new satellites". Therefore, the method is equivalent to incorporating an old satellite into a satellite network, saves the cost of adding a new satellite in the satellite network, and realizes the efficient utilization of satellite resources.
According to the technical scheme, the beneficial effects of the embodiment are as follows: the software definition transformation of the target satellite is realized by installing the program package on the target satellite, and the target satellite is incorporated into the satellite network by establishing the virtual main body, so that the high cost caused by launching a new satellite is avoided, and the efficient utilization of satellite resources is realized.
Fig. 1 shows only a basic embodiment of the method according to the invention, on the basis of which certain optimizations and developments are made, but other preferred embodiments of the method can also be obtained.
Fig. 2 shows another embodiment of a satellite call method according to the present invention. This embodiment will further describe the procedure of calling the target satellite to control the on-board device to perform a specific function based on the foregoing embodiment. In this embodiment, the method further includes the following steps on the basis of the foregoing embodiment:
step 201, determining a control program corresponding to the satellite-borne equipment.
In this embodiment, the virtual host in the target satellite can run the operating system, and a corresponding control program is already installed in the operating system. The control program is specially used for controlling the on-board device to enable the on-board device to execute various operations.
Under the operating system, the control program can be developed by the design manufacturer of the satellite or the design manufacturer of the on-board device; the operating system authority can also be opened for other software development mechanisms/personnel to develop. I.e., an application development mode similar to "smart devices".
In this step, if it is determined that a specific on-board device needs to be controlled to perform a related operation to implement some specific functions, the corresponding control program should be defined first. For example, the control program may be initiated to be in an interactable, executable state in order to perform a subsequent flow of the method.
Step 202, determining a control instruction for the on-board device; and determining a control scheme corresponding to the control instruction by utilizing the control program.
And aiming at a control instruction of the satellite-borne equipment, namely an instruction signal which triggers the satellite-borne equipment to execute related operation and describe specific operation content. The command signal may be input to the virtual body by the satellite network. Specifically, the control instruction may be a control instruction input by a person, that is, an instruction specifically input when the worker wishes to perform the related operation. Or may generate control instructions based on the operational state of the satellite. The control instructions are automatically generated, for example, according to a predetermined mechanism, when the satellite operation reaches a specific condition (e.g., reaches a specific location, or a time period).
In the control instructions, control actions and control parameters may be included. The control action is the action which needs to be completed by the satellite-borne equipment. The control parameters, namely various parameter data specifically related to the control action. The control scheme may be generated using control actions and control parameters in the control instructions. The control scheme is a specific scheme which needs to be executed by a subsequent control program in the process of controlling the on-board equipment.
And 203, controlling the on-board equipment by using the control program to execute the control scheme.
After the control scheme is determined, the on-board device can be controlled by a control program to execute the control scheme. Thereby causing the on-board device to perform the operations described in the control instructions. Thus, in this embodiment, the control of the satellite-borne device of the target satellite is realized through the satellite network.
For example, when the on-board device is an optical camera, a control program corresponding to the optical camera should be further determined. With a preset mechanism it can be set that the satellite should take 3 shots of the earth in 1 operating cycle. Assuming that one cycle of satellite operation is 24 hours, this means that the control command can be automatically generated every 8 hours. The control instruction can carry various information such as shooting times, shooting angles, related shooting parameters and the like. A control scheme may be generated based on the control instructions.
The satellite network then invokes the optical camera by controlling the virtual body. I.e. the optical camera is started and the right to control the optical camera is assigned to the control program. Then, the control program can control the optical camera to execute the control scheme. That is, the ground photographing is performed in accordance with the photographing times, photographing angles, and photographing parameters described in the control instruction.
Or when the spaceborne equipment is a momentum wheel, a control program corresponding to the momentum wheel can be further determined. When the satellite network needs to adjust the attitude of the target satellite, a control instruction is manually input. The control instruction can carry specific information such as the rotation direction, the rotation speed, the rotation angle and the like of the momentum wheel. I.e. the momentum wheel rotates according to the specific information mentioned above, the satellite attitude can be adjusted to the desired state. A control scheme may be generated based on the control instructions.
The satellite network then invokes the momentum wheel by controlling the virtual body. I.e. the momentum wheel is started and the right to control the momentum wheel is assigned to the control program. The control program then controls the momentum wheel to execute the control scheme. Namely, the satellite attitude adjusting device rotates according to the rotation direction, the rotation speed and the rotation angle described in the control instruction, thereby achieving the effect of adjusting the satellite attitude
