Satellite communication is communication performed between two or more earth stations by using an artificial earth satellite as a relay station to relay radio waves, and is an important wireless communication means. The system has been widely applied to a plurality of fields such as military affairs, ocean, rescue and relief work, aviation communication, remote medical treatment and the like for a long time. Satellite communication has traditionally been a highly available backup communication means that provides users with a unique means of communication when terrestrial and other wireless communication conditions are not available.

How to effectively manage, monitor and present on-board resources in the satellite communication process has become an integral part of satellite resource management. Meanwhile, since the information of the satellite communication resources is various and the logical relationship is complex, it is difficult to uniformly manage various satellite resources. With the increasing variety of utilized satellite resources, the traditional satellite resource management method has low efficiency and cannot accurately monitor and display the state of the satellite resources in real time. How to realize uniform and efficient management of different satellite resources has been a difficult problem in the industry.
The invention provides a satellite resource state obtaining and displaying mode, which is characterized in that a forwarding model and a communication resource model are established by analyzing the logical hierarchical relation of satellite resources, and relevant information of the satellite resources is displayed in a WEB page according to the methods of satellite presentation and frequency band presentation.
Disclosure of Invention
The invention aims to provide a method for acquiring and displaying the state of satellite resources. The invention is realized by the following steps.
Firstly, a hierarchical relationship of satellite communication resources is established, the satellite communication resources are displayed in four layers according to the hierarchical relationship of the communication satellite, namely, the communication satellite, the antenna, the wave beam and the transponder, the hierarchical relationship is shown in fig. 1, the first layer of the communication satellite communication resources comprises the satellite, a plurality of antennas contained in the satellite form the second layer, a plurality of wave beams contained in each antenna form the third layer, and a plurality of transponders contained in each wave beam form the fourth layer.
Secondly, a satellite signal forwarding model is established by analyzing the existing communication satellite forwarding mode, wherein the satellite signal forwarding model is shown as the following formula:
wherein transiIndicates a certain transponder i, id indicates a transponder number, fsDenotes the starting frequency, feIt is indicated that the frequency of termination is,
show the combination gateIs described. ModelTIndicating a certain satellite signal retransmission, comprising an up-transponder and a down-transponder, i.e. signal retransmission by transponders transi(upstream) and repeater transj(downstream) combining is completed. For the satellite signal forwarding model, the uplink transponder information and the downlink transponder information are input, and finally, the link relation of satellite signal forwarding is output. And designing a database table for signal forwarding according to the established satellite signal forwarding model.
The model can be applied to the following forwarding modes of the known communication satellite:
1) fixed frequency band cut-through forwarding: the uplink and the downlink have the same frequency band, the same wave beam and fixed configuration;
2) fixed frequency band link forwarding: the uplink and the downlink have the same frequency band, different wave beams and fixed configuration;
3) fixed link forwarding: the uplink and downlink are fixed in different frequency bands, different wave beams and configurations;
4) the straight-through and cross-linking are variable: the forwarding channel is configured with a plan and switched according to the use requirement and the load state;
5) fixed digital processing forwarding: the exchange configuration of the uplink and downlink channels is fixed, and only digital channels are provided;
6) fixed analog processing forwarding: the exchange configuration of the uplink and downlink channels is fixed, and only analog channels are provided;
7) variable digital processing forwarding: the uplink and downlink channels can be configured to be digital processing forwarding, can also be configured to be transparent forwarding, are configured with a plan, and can be switched as required;
8) variable analog processing forwarding: the uplink and downlink channels can be configured to be analog processing forwarding, can also be configured to be transparent forwarding, are configured with a plan, and can be switched as required;
9) digital-analog processing and forwarding: the uplink and downlink channels can work in digital processing and forwarding, can also work in analog processing and forwarding, are configured with a plan, and are switched according to requirements.
The core resource of the satellite communication network refers to a payload resource on a communication satellite and comprises an antenna, a frequency converter, a combiner, a power amplifier, various switches, switching equipment and the like. In the context of logical channels, the signal processing device of the payload provides a plurality of channels C of continuous frequency range, we call the processing part of the received signal the up channel Cu, and the processing part of the transmitted signal the down channel Cd. The geographic service range of each channel is determined by the particular beam B formed by the antenna to which it belongs. The uplink and downlink channels form a hinge relation R through a branching and combining device, a switch, exchange equipment and the like. The power amplifier equipment of the communication satellite can provide signal power amplification processing for a plurality of downlink channels, and the power factor of the power amplifier equipment is an important index for channel signal forwarding, so that a plurality of channels sharing the power amplifier equipment are called as repeaters T. Thus, the payload resource S provided by a communication satellite may be identified by the following five-tuple
S=(B,Cu,Cd,R,T) (2)
Wherein, B is a beam set represented by a beam central point p and an active range thereof; cu is an uplink channel, Cd is a downlink channel, and each channel can be described by a central frequency point f, a bandwidth c and a beam b to which the bandwidth c belongs; the repeater set T is a division of a downlink channel set Cd; the hinge relation R is the mapping from the set Cu to the set Cd, namely R belongs to Cu → Cd.
When the switch state in the satellite payload changes, the hinge relationship R in the satellite transponder will change, as will the beam to which the channel belongs. Thus, a particular switch state of a communication satellite is referred to as payload mode M, the corresponding payload model S under M model, also referred to as communication satellite payload model SM.
And thirdly, designing a database table for signal forwarding. In order to support the formal representation of the satellite signal forwarding model, data representation of the upper and lower repeaters and their relationship of the satellite is required in a database, and the database table contains a satellite identifier, a beam identifier, an uplink repeater identifier, a forwarding model, a repeater identifier and a downlink repeater identifier. The satellite signal forwarding model is mixed, so that the satellite signal forwarding model has not only transparent cross-link forwarding of analog signals, but also switched forwarding of baseband data signals, and also has a forwarding mode based on inter-satellite links, so that the satellite signal forwarding model has a simpler direct-through mode and a switching mode similar to a network topology.

The signal forwarding topology means that when signals are forwarded through a forwarding device located at a satellite or through a ground gateway station switching device, a signal forwarding topology is formed between the forwarding and switching devices.
And finally, displaying the state of the satellite communication resources, and displaying the satellite communication resources and the satellite communication network resources respectively. The display of the satellite communication network resources is displayed according to the inheritance relationship of the communication network, and the inheritance relationship is divided into three levels, namely a communication network type, a network and a virtual subnet.
The method comprises the following steps of dynamically displaying state information of satellites, beams, repeaters and frequency bands in the satellite communication resources, such as specific states, quantity, utilization rate, names and other data, wherein the specific states of the satellite communication resources comprise an idle state (initial state), an assignment state, an allocation state, an occupation state and a labeling state, and the meaning of each state is as follows:
idle state (initial state): a satellite communication resource configuration or an initial state after loading from a database;
assignment state: a state after the satellite communication resources are assigned to a particular communication network type;
and (3) allocation state: a state in which the satellite communication resources have been allocated to a specific task by the resource dynamic management system;
and (3) an occupied state: the state of carrier signals on the satellite communication resources comprises signals such as legal carrier occupation, illegal carrier occupation and interference;
marking the state: when the satellite communication resources are marked as reserved or used by the ad hoc network.
The transition relationship among the five states is shown in fig. 2, and there are five states of idle, allocation, occupation, labeling and assignment, wherein the idle, occupation and assignment states can be converted into four states except for self, the allocation state can be converted into an idle state, an occupation state and an assignment state, the labeling state can be converted into an idle state, an occupation state and an assignment state, and the red arrow in the figure indicates the illegal use condition of the resource.
The satellite communication resource has the following three state changes in the idle state (— > represents the state transition, and other state changes are also applicable):
the idle state- > is distributed, the system directly distributes the satellite communication resource to the specific task in the communication network, at the moment, the satellite communication resource enters into the distribution state, and the satellite communication resource is occupied by the task;

The idle satellite communication resources may be assigned to a communication network, may be directly allocated to a specific provisioning task under the communication network, and may also be marked as reserved for emergency use. Satellite communication resources assigned to the communication network may also be assigned to specific tasks or reserved for emergency use. The satellite communication resources can be occupied by terminal service communication and can also be illegally occupied.

Detailed Description
The technical solution of the present invention will be described in detail with reference to two specific examples.
The first embodiment is as follows:
when the satellite communication resource state is displayed, the information is displayed in three modes of resource overview page information, single satellite communication resource information and information presentation according to the frequency band.
The resource overview page information is displayed mainly by a graph and in a form of a table in an auxiliary mode, and relevant data information of satellites, beams, repeaters and frequency bands is displayed in a browser by using the technologies of an Html, a Css and a JavaScript front end.
The overview page graphically displays the main statistical information of the currently used communication satellite, including objects such as satellite, beam, transponder and frequency, and if more detailed information is desired to be viewed, the "detailed information" hyperlink can be clicked, and the detailed attributes of each object can be displayed in a table form after clicking (for example, when a list displays all the attributes, only the main attributes of the object are displayed by default). Some of the hyperlinks may be set as appropriate for certain attributes in the list.
According to the page design for resource browsing of a single satellite, the beam, the transponder, the frequency resource and the utilization rate of the allocated resource are mainly displayed on the page by using the technologies of the Html, the Css and the JavaScript front end. When the wave beam resources are displayed, the wave beam resources are classified and refined to the combination of the frequency band type and the wave beam type, and the WEB service acquires information by calling the unified data access service and dynamically generates a displayable graph. When the repeater resources are displayed, the repeater types and the frequency band types are classified and refined, and the WEB service acquires information by calling the uniform data access service and dynamically generates displayable graphs. When frequency resources are displayed, the frequency resources are subdivided into three types of allocated, idle and unassigned, and the WEB service acquires information by calling a uniform data access service to dynamically generate a displayable graph. When the utilization rate of the allocated resources is displayed, the resources of one satellite are assigned to be allocated to different types of networks, so that the utilization rate statistics needs to be carried out according to the network types and the frequency band types, the statistical particle rate is not less than 1 day (taking day as a unit), the utilization rate statistics is reported or actively obtained after being calculated by using units (networks, subnets and tasks), and then is obtained after being normalized by background resource dynamic management service, and is a statistical mean value, the weight of each reported statistic in the final calculation is related to the amount of the resources allocated to the statistic, and the resource utilization rate calculation formula of the allocated specific frequency band f is as follows:
λfi＝(ωn1×n1λi+ωn2×n2λi+...+ωnk×nkλi)×αf(3)
where i denotes the ith sampling time point, ωnkRepresents the weight of the kth network, nk λiIndicating the utilization of network k at the ith sample point, αfAnd (3) representing the allocation rate of resources, a special table needs to be designed to store statistics in units of single satellite frequency band types.
The page display design presented by frequency band includes two parts of content: the first part is the accumulated information of all satellites in a certain frequency band, including total, assigned (distributed, idle), public (not assigned), beam number and transponder number; the second part is the utilization ratio of the frequency band frequency resource, the utilization ratio of the frequency band on a certain time granularity is displayed, the time granularity is not less than 1 day, and the frequency utilization ratio calculation formula of the specific frequency band f is as follows:
where i denotes the ith sampling time point within the statistical time period, n denotes the total number of sampling points, bandiRepresenting the amount of bandwidth used, band, acquired at a sample pointfRepresenting the amount of bandwidth allocated at the sampling point.
In the graph region of the utilization rate, information on the number of intersections of the vertical line of the mouse point and the utilization rate curve is displayed in a Hint fashion as the mouse is moved. Paging according to frequency bands, wherein each frequency band occupies one page, and if the current browsing is according to the frequency bands, a pull-down selection frame is adopted to enable a display page to rotate among different frequency band pages.
The statistical information and the utilization rate information are obtained by calling a data access service of a background. And designing a special table for storing statistics in unit of single satellite frequency band types. The background service performs normalization calculation on the utilization rate information of the related frequency band resources through the acquired task networks, stores the information into a statistical table taking the frequency band as a statistical object, can store the information by taking a single satellite as a unit, and can push the information to the WEB service after normalization calculation is performed during data access.
Example two:
firstly, a model is represented in a data manner, and the structure of a database is determined according to the hierarchical relationship among satellites, antennas, beams and forwarding. Wherein the design of the satellite data base table is shown as a table.

| 1 | Satellite identification | Satellite identification, all uniqueness guaranteed | |
| 2 | Satellite name | Satellite name |
The design of the library table for the antenna model datamation representation is shown as a table. Since the satellite antenna parameters are related to power calculation, the required parameter information can be increased as required.

The design of the library table for the beam model datamation representation is shown as a table. The beam is a shape formed on the earth surface by electromagnetic waves emitted from a satellite antenna, and mainly includes a global beam, a spot-shaped beam and a shaped beam. They are shaped by the transmitting antenna.

The design of a library table for a transponder model data representation is shown as a table

The hierarchical relationship of the satellite, the antenna, the beam and the transponder is shown through the foreign key constraint relationship of the database, the satellite forms a first layer of communication resources of the communication satellite, a plurality of antennas included in the satellite form a second layer, a plurality of beams included in each antenna form a third layer, and a plurality of transponders included in each beam form a fourth layer, as shown in fig. 3. Fig. 3 shows a multi-level list, which is widely applied to WEB, GUI, APP, or the like, and can clearly show the hierarchical relationship of resources.
Thirdly, a database table for signal forwarding is designed according to a formula for establishing a satellite signal forwarding model, wherein the model represents that a satellite signal is forwarded by an uplink repeater transiAnd downstream repeater transjThe combination of (a) and (b) is completed. In order to support a formal representation of the satellite signal forwarding model, data representation of the satellite's context transponders and their relationships in a database is required. Because the satellite signal forwarding model is relatively mixed, the model has not only transparent cross-link forwarding of analog signals, but also switched forwarding of baseband data signals, and also a forwarding mode based on inter-satellite links, so that the model has a relatively simple through mode and a switching mode similar to a network topology, as shown in table 6.
Table 6 signal transfer relation data table
After the signal forwarding relationship is determined, the satellite frequency resource generally refers to a certain range of resources selected from the satellite signal forwarding combination relationship, but due to the variability of the satellite signal combination relationship, in order to make the satellite frequency model not affected by the signal forwarding, the frequency resource forms an individual data table, as shown in table 7, only the range of the downlink frequency needs to be concerned, and the range of the uplink frequency can be estimated through the forwarding relationship in the table.
TABLE 7 frequency resource data
And finally, according to the state of the frequency resource stored in the system database, the state of the satellite communication resource can be displayed, and the display can be performed in a histogram mode. As shown in FIG. 4, the bar of the rectangle represents a segment of the resource, and the number in the bar, for example, 20-1, where 20 represents occupied bandwidth and 1 represents type allocation.
