Description

System for telemetry command execution of satellite and method about, its program stored recording medium}

The present invention relates to a system and method for confirming the execution of a remote command of a satellite, and more particularly to a recording medium storing a program thereof, and more particularly, to a system and a method for confirming the execution of a remote command of a satellite which can automatically confirm the execution of a remote command transmitted to the satellite. And the recording medium on which the program is stored.

The satellite control system receives and processes telemetry data from satellites, analyzes satellite status data, attitude and orbit data, plans tasks, and transmits remote commands to satellites to perform its intended task.

In the above, the telemetry data is the status values for the component equipment and the system of each satellite sub-system, thereby allowing the status of the satellites to be determined. The satellite control system grasps the state of the satellite through telemetry data, and then sends a remote command to the satellite to perform a new task or change the state of the satellite.

At this time, the satellite control system should check the telemetry data transmitted from the satellite to verify that the remote command is properly performed after transmitting the remote command.

That is, when the satellite control system sends a remote command to a satellite to open or close a switch, it reads the value of the telemetry data indicating the state of the switch to confirm that the switch is opened or closed as the operator intended.

Such a remote command of opening and closing the switch can check whether or not the remote command is performed by checking one predetermined telemetry data value, but many other remote commands often need to check one or more telemetry data values.

In this case, a method of checking a plurality of telemetry data values for a single remote command has been proposed by introducing a knowledge base to determine whether to perform a remote command.

However, the method of checking the knowledge base telemetry data is possible only when there are experts who define the rules of the knowledge base, and it is impossible to perform it when there is no such expert or when the response of the telemetry data to the telecommand is not clearly known. There is a problem.

The present invention is to solve the above problems, an object of the present invention is to determine whether to perform the remote command using a data table that stores the change value of the remote command and telemetry data without relying on a knowledge base To provide a satellite remote command performance confirmation system and method, and a recording medium storing the program.

In step a), the data table includes an observation table indicating a change value of the value for observation, and a value table indicating an average rate of change of the telemetry data.

The observation table continuously increases data through the operation of the satellite control system, and the value table is modified as the data of the observation table increases. The observation table comprises the j-th telemetry data (Tc) obtained by transmitting c-th from the set (Tc) of the set of the telecommand and the satellite (Tc) of the satellite on which a specific element (c) of the set of the remote command is executed. The changed values (O _c-ij ) of) are shown in table form.

The value table comprises a set of previously telecommanded and a set of telemetry data (Tc) of satellites on which a particular element (c) of the set of remote commands is executed. When c is transmitted, a value (V _{c-ij, 0} ≦ V _{c-ij ≦} 1) obtained by dividing the number of observations in which the value of the telemetry data T _cj is changed by i is expressed in a table form.

The value table is _{composed of} V _c-0j + V _c-1j + V _c-2j +... For one telemetry data T _cj . … The value of. + V _c-nj converges to one.

Extracting data from the data table in step b),

Exclusion; C) When transmitting c in step a), all T _cj satisfying V _c-hj = 1 (1 ≦ j ≦ m, 1 ≦ _h ≦ n) are found and excluded from the element of Tc, (T _cj , h) registering as an element of the data set Sol = {(T _cj , h)}; D) searching for T _cj when i, with V _c-oj = 0 and V _c-ij > 0, exceeding the reference value, and excluding it from the element of Tc when transmitting c in step a); E) When transmitting c in step a), if there is no T _cj satisfying V _c-oj = 0 and V _c-ij = 1 and the value of i with V _c-ij > 0 does not exceed the reference value, Since the T _cj is associated with the change in T _ck , ((T _cj , i) → (T _ck , _i'k )), the data set (Sol = {(T _cj , h), ((T _cj , i) → registering as an element of (T _ck , i 'k))}); And f) terminating the data extraction process if the number of elements of Tc is less than 1 after performing step d) in step b).

In step b) and step e), the observation table and the value table are rewritten according to the change of Tc. In step d) and e), the reference value of i (1 ≦ i ≦ n) is set to n / 5.

The step of checking whether the remote command is performed in step c) includes the elements of the data set Sol = {(T _cj , h), (T _cj , i) → (T _ck , _i'k )}). When the value of T _cj increases by h, the value of T _cj increases by i and the value of T _ck increases by i 'k, it is confirmed that the remote command (c) is executed. do.

On the other hand, a feature of the satellite remote command performance confirmation system according to the present invention, the signal processing unit for receiving the telemetry data transmitted from the satellite via the antenna to convert the signal into a system processable signal; A telemetry data processor for extracting data available to the operator from the signal of the telemetry data output from the signal processor; A data management unit for creating the data extracted from the remote measurement data processing unit in the form of a data table and outputting remote command confirmation data for confirming whether or not a specific remote command is performed; And a remote command processing unit receiving the remote command confirmation data from the data management unit, analyzing the remote command confirmation data, planning a mission for satellite operation, and transmitting the remote command to the satellite.

The data set Sol = {(T _cj , V _c-ij ), (T _cj , V _c-ij → T _ck , V _c-i'k )},

When the remote command (c) is transmitted, T _cj satisfying V _c -hj = 1 (1 ≦ j ≦ m, 1 ≦ _h ≦ n) is found, and (T _cj , h) is registered as an element, and V _{c- If} there is no T _{cj oj} = 0 and satisfying V _c-ij = 1 and the value of i with V _{c -ij} > 0 does not exceed the reference value, then the T _cj is associated with the change in T _ck .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 illustrates a configuration of a system for confirming remote command execution of a satellite according to an embodiment of the present invention.

As shown in FIG. 1, the satellite control system 200 includes a signal processor 210, a telemetry data processor 220, a data manager 230, and a remote command processor 240. Include.

The signal processor 210 receives the telemetry data transmitted from the satellite 100 through an antenna, converts the signal into a system-processable signal, and burns it to the telemetry data processor 220.

The telemetry data processing unit 220 extracts the signal of the telemetry data output from the signal processing unit 210 as data available to the operator, and the data management unit 230 stores the data extracted from the telemetry data processing unit 220 in a table. It forms and manages the form, and transmits the remote command confirmation data confirming whether or not the remote command is performed through the data table to the remote command processing unit 240.

The remote command processor 240 receives the remote command confirmation data from the data manager to plan a mission for satellite operation, and transmits the remote command to the satellite through the signal processor 210 and the antenna.

FIG. 2 illustrates a configuration of a data management unit that is a part of FIG. 1.

As shown in FIG. 2, the data manager 230 includes a data collector 231, a data extractor 233, and a remote command execution checker 234.

The data collection unit 231 collects telemetry data and remote commands and stores the data in the data table 232. The data extracting unit 233 analyzes the data stored in the data table 232, extracts remote command confirmation data for confirming the execution of a specific remote command, and outputs remote command confirmation data.

The remote command execution confirmation unit 234 determines whether to perform the corresponding remote command using the remote command confirmation data output from the data extraction unit 233.

In the above, the data table 232 stores the observation table and the value table.

First, the observation table (Oc) shows the change of the telemetry data value, that is, the value of the observation value, in the form of a table with respect to the remote command c. The data is continuously increased through the operation of the satellite control system. Can be.

For example, the set of telecommands used for multipurpose practical satellite # 2 control is called CMD, and the set of telemetry data is called TLM.

If Tc = {T _c-1 , T _c-2 , T _c-3, .., T _cm }, the set of TLM elements corresponding to the satellite subsystem in which element c of CMD is executed, Tc ⊂ TLM is do.

When the element c of the CMD is transmitted, the set of changing values of Tc is referred to as Oc, and the element O _{c- ij} denotes the changed value of the j th Tc obtained by transmitting the c ith .

Observation table (Oc) is as shown in Table 1 below, Oc makes a table as many as the number of elements of the CMD, the data can be collected while operating the satellite control system, the number of observations (Obs #) will continue to increase .

On the other hand, as shown in Table 2, the value table (Vc) is a table representing the average value change rate of the telemetry data, it is used as a data table for extracting the telemetry data from the data extraction unit 233. This value table should be modified as the contents of the observation table increase.

That is, the value table is constructed to have a function that aggregates the contents of the observation table because the observation table has difficulty in constructing the case base directly.

In Table 2, the column of Vc is Tc, and the column is a range of values where each T _{c- j} changes when the remote command c is transmitted.

Where V_{c- ij} Is T when remote command c is sent._{c- j} The number of observations for which is changed by i divided by the total number of observations, where 0≤ V_c-ijIt has a value of ≤ 1 and one telemetry data (T_{c- j} V)_{c- 0j} + V_{c-1 j} + V_{c-2 j} + ... + V_{c- ij} + ... + V_{c- nj} = 1

When sending a remote command c that is an element of CMD, we need to find the data set (Sol = {}), which is a set of T _cj and its value, to confirm that c was executed.

At this time, the elements of the dataset should be extracted from Tc using the characteristics of Vc. The characteristics of Vc are listed below.

1) V_{c- 0j} When> 0, T_{c- j} Since T includes no change in Tc when c is sent,_{c- j} Cannot be an element of a data set (Tol) (T_{c- j} Cannot be an element of Sol.)

2) When V _{c- ij} (1 ≤ i ≤ n) = 1, T _{c- j} changes Tc constantly when c is transmitted, so (T _{c- j} , V _{c- ij} ) do.

3) V_{c- 0j} V is 0_{c- ij} If i has a relatively large value of (1? I?_{c- j} Cannot be an element of Sol.

4) V_{c- 0j} = 0 and V_{c- ij} T satisfying (1≤i≤n) = 1_{c- j} Even if there is no_{c- ij} (1≤i≤n)> 0, i is relatively less and they are different T_{c- k} If the change is constant when c is sent in conjunction with a change of (1≤k≤n), then (T_{c- j} , V_{c- ij} T_{c- k} , V_{ci 'k}) Is an element of Sol.

The meaning of 'relatively many' among the above characteristics can be adjusted by the user, but in the embodiment according to the present invention, the value is greater than n / 5.

Looking at the operation of the remote command performance confirmation system of the satellite according to the embodiment of the present invention configured as described above with reference to the accompanying drawings.

Table 3 shows an example of the observation table. The observation table prepared in Table 3 has a total of ten observations, and shows the change of the seven telemetry data values in the form of a table for the remote command c.

Table 4 shows the value table which the observation table of Table 3 summarized based on the content.

3 is a flowchart illustrating a method for confirming remote command execution of a satellite according to an embodiment of the present invention.

As shown in FIG. 3, the data collection unit 231 generates a data set based on Tables 3 and 4, wherein the data set is an empty set (S1).

At S1, Tc = {T _c-1 , T _c-2 , T _c-3 , T _c-5 , T _c-5, T _c-6 T _c-7 }, Sol = {}.

Introducing the characteristics of Vc mentioned above, Tc _-2 and Tc _{-6 are} excluded from Tc by the characteristics of the first Vc, and new observation table (Oc) and value table (Vc) using new Tc are newly created. (S2)

In S2, each newly created table is shown in Tables 5 and 6, with Tc = {T _c-1 , T _c-3 , T _c-4 , T _c-5 , T _c-7 }, Sol = { } Becomes

Next, by introducing the second characteristic of Vc, in Tables 5 and 6, T _{c-3 is} excluded from Tc, (T _c-3 , 1) is added to the data set (Sol), Oc and Vc are newly produced (S3).

In step S3, the newly prepared Oc and Vc are shown in Table 7 and Table 8, respectively, and Tc = {T _c-1 , T _c-4 , T _c-5 , T _c-7 }, Sol = {(T _{c -3} , 1)}.

Introducing a third characteristic of Vc haebomyeon Table 7 and will be excluded from the _{T-1 c} is Tc in Table 8, is produced newly Oc and Vc using Tc is the T _c-1 negative. (S4)

In step S4, the newly created Oc and Vc are shown in Table 9 and Table 10, respectively, and Tc = {T _c-4 , T _c-5 , T _c-7 }, Sol = {(T _c-3 , 1) } Becomes

From the above, it is determined whether the number of remaining elements except for some elements of Tc is greater than 1 by the property of Vc. In step S4, the fourth characteristic of Vc is introduced since the number of elements of Tc is greater than 1 (S5).

As a result, V _{c- 34} and V _c-55 , which have the largest value among V _c-ij , do not find a satisfying T _ck , but V _c-44 represents 1.0 with V _c-55 . (T _c-4 , 4) → (T _c-5 , 5) is included in the data set (Sol), and T _c-4 and T _c-5 are excluded from Tc (S6).

The newly created Oc and Vc in step S6 are shown in Table 11 and Table 12, respectively, and Tc = {T _c-7 ,}, Sol = {(T _c-3 , 1), (T _c-4 , 4) → (T _c-5 , 5)}.

If the number of remaining elements in Tc is less than or equal to 1, then all processes for finding the elements of the dataset are terminated.

Through the data set obtained above, the remote command execution confirmation unit 234 increases the value of T _c-3 by 1, increases the value of T _c-4 by 4, and increases the value of T _c-5 by 5. If all the conditions are met, the remote command c is executed.

The method of the embodiment according to the present invention mentioned above has the flexibility to be easily programmed using a general programming language and to be easily incorporated into a satellite control system since it does not use a special data structure.

As described above, the embodiment according to the present invention does not require an expert to build a knowledge base, and as the satellite operation continues, more data can be collected and more faithful to data analysis, so a 'learning' effect can be expected. In addition, it is possible to automatically compare the telemetry data extracted through the data table with the telemetry data received in real time, thereby minimizing operator intervention.
