In view of the above, the embodiments of the present invention provide a fast scheduling system for unmanned aerial vehicle resources, which is used for solving the technical problems involved in the foregoing.
Example 1
Fig. 1 is a schematic system structure diagram of a fast scheduling system for unmanned aerial vehicle resources according to an embodiment of the present invention, as shown in fig. 1, where the system includes: unmanned aerial vehicle task control device, communication satellite, satellite terminal and satellite resource management and control center of communication satellite.
The unmanned aerial vehicle task control device receives a satellite resource use application sent by at least one unmanned aerial vehicle user and sends the satellite resource use application to a satellite communication terminal of a communication satellite.
And the satellite communication terminal forwards the satellite resource use application to the satellite resource management and control center through the communication satellite.
The satellite resource management and control center determines a satellite resource allocation plan based on available satellite resources and satellite resource use applications sent by at least one unmanned aerial vehicle user, and sends the satellite resource allocation plan to the satellite terminal through the communication satellite.
And the satellite communication terminal forwards the satellite resource allocation plan to the unmanned aerial vehicle task control device.
The unmanned aerial vehicle task control device loads a satellite resource allocation plan to organize a link between the unmanned aerial vehicle and a satellite ground station based on the satellite resource allocation plan, so that the unmanned aerial vehicle can complete a specified task based on the allocated satellite resource.
In the embodiment of the invention, the satellite resource management and control center establishes a special satellite network specially used for the unmanned aerial vehicle to apply for satellite resources, and authorized unmanned aerial vehicle users join the special satellite network to maintain a satellite link with the satellite resource management and control center in a normalized mode. The satellite resource management and control center simultaneously develops special unmanned aerial vehicle resource management system software, and deploys the special unmanned aerial vehicle resource management system software on the special satellite communication network, and all terminals in the special satellite communication network are provided with the unmanned aerial vehicle resource management system software. By accessing the software, the unmanned aerial vehicle user can acquire the current applicable quantity of the residual satellite resources, the satellite resource history records applied by the unmanned aerial vehicle user, and the like.
When unmanned aerial vehicle user has satellite resource use plan, will send satellite resource use application to unmanned aerial vehicle task control device rather than communication connection through the interaction with the software terminal, unmanned aerial vehicle task control device be with a plurality of unmanned aerial vehicle user keep the system architecture of normal connection, can interact with unmanned aerial vehicle user, still provide the data transmission passageway with between the satellite resource for unmanned aerial vehicle.
After receiving the satellite resource use application sent by at least one unmanned aerial vehicle user, the unmanned aerial vehicle task control device sends the satellite resource use application to the communication satellite through a satellite communication terminal of the communication satellite, wherein the satellite communication terminal of the communication satellite refers to a data terminal deployed on the ground and is a data forwarding platform of the communication satellite and an authorized user thereof.
After receiving the application for using the satellite resources, the communication satellite forwards the application to a satellite resource management and control center, and after receiving the application for using the resources, the satellite resource management and control center determines an application queue of the unmanned aerial vehicle after completing resource conflict resolution (users all need to apply for a certain section of resources and overlap in time, so that conflict resolution is needed, generally 2 resolution methods are staggered in time and frequency), and priority order, and performs resource allocation according to a preset algorithm, thereby preparing a satellite resource allocation plan, wherein the satellite resource allocation plan is to determine that a certain section of resources of a certain satellite are allocated to a certain unmanned aerial vehicle user for use in a certain period of time.
After the satellite resource management and control center determines the satellite resource allocation plan, the satellite resource allocation plan is sent to the satellite communication terminal through the communication satellite, and the satellite communication terminal forwards the satellite resource allocation plan to the unmanned aerial vehicle task control device. After the unmanned aerial vehicle task control device obtains the satellite resource allocation plan, each unmanned aerial vehicle which is organized according to the plan and uses the satellite resource in a batch builds a chain with the satellite ground station in each plan time period, so that the unmanned aerial vehicle completes the appointed task based on the allocated satellite resource.
For ease of understanding, it is assumed that the unmanned aerial vehicle users transmitting the satellite resource usage applications are a, B, C, and D, but only the satellite resource usage applications of a, B, and C are approved due to the resource occupation conflict, so the satellite resource allocation plan includes at least a first satellite resource approved by a and an authorized resource occupation time (denoted as a first plan time period), a second satellite resource approved by B and an authorized resource occupation time (denoted as a second plan time period), and a third satellite resource approved by C and an authorized resource occupation time (denoted as a third plan time period).
After the unmanned aerial vehicle task control device loads the satellite resource allocation plan, the unmanned aerial vehicle user A and the satellite ground station are organized to build a chain at the starting time of the first planning time period, so that the unmanned aerial vehicle user A can complete the appointed task through the first satellite resource. And so on, organizing the link establishment between the unmanned aerial vehicle user B and the satellite ground station at the starting time of the second planning time period so that the unmanned aerial vehicle user B completes the appointed task through the second satellite resource; and organizing the link establishment between the unmanned aerial vehicle user C and the satellite ground station at the starting time of the third planning time period so that the unmanned aerial vehicle user C completes the appointed task through the third satellite resource.
The invention provides a rapid unmanned aerial vehicle resource scheduling system, which comprises: unmanned aerial vehicle task control device, communication satellite, satellite terminal and satellite resource management and control center of communication satellite. The system builds a special satellite communication network special for the unmanned aerial vehicle to apply for satellite resources, and after the unmanned aerial vehicle user joins the satellite communication network and sends a satellite resource use application to the satellite resource management and control center through the network, the satellite resource management and control center can automatically generate and transmit back a satellite resource allocation plan, so that the technical problem of low resource scheduling efficiency in the existing unmanned aerial vehicle resource scheduling method is effectively solved.
In an alternative embodiment, the satellite resource usage application includes: usage frequency band, beam class, forward bandwidth, reverse bandwidth, forward data transmission rate, reverse data transmission rate, usage period, flight zone, and mission level.
The satellite resource management and control center determines a satellite resource allocation plan based on available satellite resources and a satellite resource usage application transmitted by at least one unmanned aerial vehicle user, comprising:
and determining the priority of each unmanned aerial vehicle user based on the task level in the satellite resource use application sent by at least one unmanned aerial vehicle user.
Determining an application queue of the unmanned aerial vehicle users according to a preset ordering rule and the priority of each unmanned aerial vehicle user; the preset ordering rule comprises the following steps: the higher priority is ranked earlier than the lower priority, the earlier the same priority take-off time is, the earlier the ranking is.
And sequentially receiving satellite resource use applications of each unmanned aerial vehicle user according to the application queue, and distributing available satellite resources based on a preset algorithm to determine a satellite resource distribution plan.
The satellite resource management and control center rejects the satellite resource use application with the resource application conflict, and feeds back the reject reason to the corresponding unmanned aerial vehicle user.
In the embodiment of the invention, when the unmanned aerial vehicle user submits the application of using the satellite resources on the resource management software according to the flight plan of the unmanned aerial vehicle user, the use frequency band, the beam type, the forward bandwidth, the reverse bandwidth, the forward data transmission rate, the reverse data transmission rate, the use period, the flight region and the task level are required to be provided, wherein the use frequency band, the beam type, the forward bandwidth, the reverse bandwidth, the forward data transmission rate, the reverse data transmission rate and the flight region are basic parameter limits of the satellite resources to be applied, and because the basic parameters of different satellite resources may have differences, the unmanned aerial vehicle user is required to be allocated with the satellite resources meeting the requirements to complete the appointed task.
The usage period, i.e. the period of time in which satellite resources are planned to be occupied, the tasks performed by the unmanned aerial vehicle include: training, testing, maintaining and the like, system management personnel should configure corresponding task levels for each task according to actual needs, and when the application is submitted, unmanned plane users need to report the corresponding task levels according to the specific executed tasks.
After receiving the satellite resource use application sent by at least one unmanned aerial vehicle user, the satellite resource management and control center firstly determines the priority of the corresponding unmanned aerial vehicle user according to the task level in each satellite resource use application. For example, the higher the task level, the higher the priority, with the lowest priority for the primary task. If the task level of the unmanned aerial vehicle user A is one level, the task level of the unmanned aerial vehicle user B is one level, and the task level of the unmanned aerial vehicle user C is two levels, then the priority of the unmanned aerial vehicle user C is highest, and the unmanned aerial vehicle user A and the unmanned aerial vehicle user B are both low priority.
Then, the satellite resource management and control center sorts all unmanned aerial vehicle users submitting satellite resource use applications according to a preset sorting rule according to the determined priority of each unmanned aerial vehicle user and the departure time of each unmanned aerial vehicle user (namely the starting time of the planned time period), so as to obtain an application queue of the unmanned aerial vehicle users. Known preset ordering rules include: the higher the priority is ranked ahead than the lower priority, the earlier the take-off time of the same priority is, the more ahead the ranking is, so along with the above example, the highest priority of the unmanned aerial vehicle user C is known, so that the unmanned aerial vehicle user C is ranked at the first position of the application queue, the unmanned aerial vehicle user a and the unmanned aerial vehicle user B are both low priority, the take-off time of the unmanned aerial vehicle user a is assumed to be earlier than that of the unmanned aerial vehicle user B, then the unmanned aerial vehicle user ranked at the second position of the application queue is denoted as a, and the unmanned aerial vehicle user B is ranked at the last position of the application queue.
After the application queue of the unmanned aerial vehicle users is determined, the satellite resource management and control center sequentially receives satellite resource use applications of each unmanned aerial vehicle user according to the sequence in the queue, and allocates available satellite resources according to a preset algorithm to determine a satellite resource allocation plan. In the process of planning, if the conflict exists between the resource utilization plan and the determined satellite resource allocation plan when the satellite resource utilization application of a certain unmanned aerial vehicle user is accepted, the satellite resource management and control center rejects the satellite resource utilization application of the unmanned aerial vehicle user and feeds the rejection reason back to the corresponding unmanned aerial vehicle user. And then the unmanned aerial vehicle user can report the satellite resource use application to the satellite resource management and control center again after adjusting the flight plan according to actual conditions.
After the unmanned aerial vehicle user finishes the designated task by using the allocated satellite resources, in an optional implementation manner, the unmanned aerial vehicle task control device is further used for receiving a satellite resource use ending application sent by the target unmanned aerial vehicle user and sending the satellite resource use ending application to the satellite communication terminal.
And the satellite communication terminal forwards the satellite resource use ending application to the satellite resource management and control center through the communication satellite.
And the satellite resource management and control center releases the corresponding satellite resources to the idle resource pool according to the application of ending the use of the satellite resources.
Specifically, considering that various accidents may occur in the unmanned aerial vehicle in the flight process, the flight time is prolonged, so if other unmanned aerial vehicle users also use satellite resources occupied by the target unmanned aerial vehicle users in the self-defined time period after the planned time period, the unmanned aerial vehicle task control device automatically cuts off the communication link between the target unmanned aerial vehicle and the satellite ground station according to the ending time of the planned time period; otherwise, the target unmanned aerial vehicle user can not disconnect the use of the satellite resources until the target unmanned aerial vehicle user sends an application for ending the use of the satellite resources. The target drone user represents any one of a plurality of drone users that perform a specified task with the allocated satellite resources.
After the target unmanned aerial vehicle flies, the resource occupation condition is terminated through resource management software, and the satellite resource use ending application and the satellite resource use application have the same data flow direction, which are all unmanned aerial vehicle task control devices, satellite communication terminals, communication satellites and satellite resource management and control centers. After receiving the application of ending the use of the satellite resources, the satellite resource management and control center releases the corresponding satellite resources to the idle resource pool so as to recover the resources and facilitate the subsequent task resource allocation. The satellite resource management and control center can grasp the satellite resource allocation, use and residual conditions in real time through resource management software.
In an alternative embodiment, the unmanned aerial vehicle task control device includes: unmanned aerial vehicle mission planning system, satellite data chain subsystem and unmanned aerial vehicle control system.
The unmanned aerial vehicle task planning system is used for interacting with unmanned aerial vehicle users and determining a link construction plan of the unmanned aerial vehicle and a satellite ground station based on a satellite resource allocation plan.
The unmanned aerial vehicle control system is used for providing a data transmission channel for the unmanned aerial vehicle, the unmanned aerial vehicle task planning system and the satellite data link subsystem.
The satellite data link subsystem is used for providing a data transmission channel for the unmanned aerial vehicle and satellite resources.
After receiving the satellite resource allocation plan, the unmanned aerial vehicle task control device directly injects the allocation plan into a satellite data link subsystem, and functions such as beyond-sight real-time remote control and remote measurement of the unmanned aerial vehicle, beyond-sight real-time transmission of the unmanned aerial vehicle reconnaissance image information and the like can be realized through the satellite data link subsystem. The satellite resource management and control center can also master the resource use state of the unmanned aerial vehicle in real time when flying beyond the line of sight through unmanned aerial vehicle resource management software.
In an alternative embodiment, the satellite resource management center includes: the system comprises a guard device and an unmanned aerial vehicle resource management software server, wherein the guard device is in communication connection with the unmanned aerial vehicle resource management software server.
The satellite communication device is used for carrying out data communication with a communication satellite.
