Telemetry has been widely used in the field of satellite technology, where a satellite system transmits telemetry data in the form of telemetry frames to a ground system via a telemetry channel for personnel to monitor the applications and equipment on the satellite system.

Satellite systems typically transmit telemetry to terrestrial systems in two ways: 1) According to the conventional telemetry, a scheduling application on a satellite system periodically triggers a plurality of applications and/or a plurality of devices to perform corresponding detection according to preset telemetry scheduling information (namely, first scheduling information), sends a conventional telemetry packet (namely, a first telemetry packet) containing a detection result to the telemetry application, and frames and transmits the first telemetry packet to a ground system by the telemetry application; 2) And inquiring telemetry, wherein the satellite system receives an inquiry command sent by the ground through a remote control channel, triggers a target application and/or a target device to perform corresponding detection according to the inquiry command, and sends an inquiry telemetry packet containing a detection result to the telemetry application.

However, both of the above telemetry approaches have deficiencies. Conventional telemetry generally monitors a plurality of applications and/or a plurality of devices on a satellite system according to deployed telemetry schedule information (i.e., first schedule information), so that the conventional telemetry cannot provide telemetry data of a target application and/or a target device to a worker, and the ground system also needs to extract telemetry data of a target application and/or a target device designated by the worker from the conventional telemetry data, thus being inconvenient to use. The inquiry telemetry can only trigger a plurality of applications and/or a plurality of devices to carry out corresponding detection in real time according to the inquiry command of the ground system and return an inquiry telemetry packet. It is therefore inconvenient to have the surface system continuously send query commands if it needs to continuously obtain telemetry data for the target application and/or target device.

When the telemetry data of a plurality of objects is transmitted to a ground system by using conventional telemetry, the telemetry data of a target application and/or a target device cannot be provided; when the remote measurement data of the target application and/or the target equipment is transmitted to the ground system by using the query remote measurement, the ground system needs to continuously transmit query instructions to the satellite system, so that the technical problem of complicated operation process is solved, and an effective solution is not provided at present.

Disclosure of Invention

The embodiment of the disclosure provides a telemetry method, a device and a storage medium based on configuration information, which at least solve the problem that telemetry data of a target application and/or a target device cannot be provided when telemetry data of a plurality of objects are sent to a ground system by using conventional telemetry in the prior art; when the remote measuring data of the target application and/or the target equipment is sent to the ground system by using the inquiry remote measuring, the ground system needs to continuously send inquiry instructions to the satellite system, so the technical problem of complicated operation process is solved.

According to an aspect of the embodiments of the present disclosure, there is provided a telemetry method based on configuration information, applied to a satellite system, including: triggering a plurality of objects to generate a first telemetry package according to first scheduling information deployed on the satellite system, wherein the first scheduling information indicates a scheduling period for conventional telemetry of the plurality of objects on the satellite system; extracting a second telemetry packet corresponding to the target object from the first telemetry packet according to first configuration information deployed in the satellite system, wherein the first configuration information is used for indicating the target object selected from the plurality of objects; generating a corresponding first telemetry frame from the second telemetry packet; and downlink the first telemetry frame to the surface system.

According to another aspect of the embodiments of the present disclosure, there is also provided a telemetry device based on configuration information, applied to a satellite system, including: a processor; and a memory coupled to the processor for providing instructions to the processor for processing the following processing steps: triggering a plurality of objects to generate a first telemetry package according to first scheduling information deployed on the satellite system, wherein the first scheduling information indicates a scheduling period for conventional telemetry of the plurality of objects on the satellite system; extracting a second telemetry packet corresponding to the target object from the first telemetry packet according to first configuration information deployed in the satellite system, wherein the first configuration information is used for indicating the target object selected from the plurality of objects; generating a corresponding first telemetry frame from the second telemetry packet; and downlink the first telemetry frame to the surface system.

According to the technical scheme of the disclosure, firstly, a telemetry application triggers a plurality of objects to generate a first telemetry package (namely, a conventional telemetry package) according to first scheduling information (namely, telemetry scheduling information) deployed in a satellite system. Wherein the first scheduling information is used to indicate a scheduling period for conventional telemetry of a plurality of objects on the satellite system. The telemetry application then extracts a second telemetry package (i.e., a configuration telemetry package) corresponding to the target object from the first telemetry package based on the first configuration information deployed at the satellite system. Wherein the first configuration information is used to indicate a target object selected from a plurality of objects. And wherein the second telemetry package includes telemetry data for the target object. In addition, the telemetry application generates a corresponding first telemetry frame (i.e., a configuration telemetry frame) from the second telemetry packet. Finally, the telemetry application downlinks the first telemetry frame to the surface system.

Since in the technical solution of the present disclosure, the telemetry application can generate the first telemetry frame according to the second telemetry packet, and the second telemetry packet is extracted from the first telemetry packet according to the first configuration information, the telemetry application in the satellite system can continuously transmit the first telemetry frame corresponding to the target object to the ground system. And the ground system can directly receive the first telemetry frame corresponding to the target object, which is sent by the telemetry application in the satellite system, so that the ground system can directly send the first telemetry frame corresponding to the target object to a worker, and the telemetry data of the target object does not need to be additionally obtained from the conventional telemetry data. Therefore, the technical scheme of the disclosure achieves the technical effects that the working personnel can directly acquire the telemetering data of the target object transmitted by the satellite system and the operation process of acquiring the telemetering data of the target object is simplified. Further, the problem that telemetry data of a plurality of objects cannot be provided when conventional telemetry is used for sending the telemetry data of the objects to a ground system in the prior art is solved; when the remote measuring data of the target application and/or the target equipment is sent to the ground system by using the inquiry remote measuring, the ground system needs to continuously send inquiry instructions to the satellite system, so the technical problem of complicated operation process is solved.

Fig. 3 is a schematic diagram of a measurement and control system in the ground system 20 according to an embodiment of the present application. Referring to fig. 3, a user interface, a measurement and control module, a remote control module, and a telemetry module are disposed in the measurement and control system. The measurement and control module further comprises a conventional measurement and control unit and a configuration measurement and control unit. The staff can interact with the measurement and control module through the user interface. Specifically, the staff sets first scheduling information related to conventional telemetry in the conventional measurement and control unit through a user interface. Wherein the first scheduling information is used to indicate a scheduling period for conventional telemetry of a plurality of objects on the satellite system 10, so that the satellite system 10 can periodically return telemetry data of each object (e.g., application or device) according to the scheduling period. The staff member can also set first configuration information related to configuration telemetry in the configuration measurement and control unit through the user interface, wherein the first configuration information is used for indicating a target object on the satellite system 10 so as to periodically acquire telemetry data of the target object in real time. Then, the conventional measurement and control unit sends the first scheduling information to the remote control module, and the configuration measurement and control unit sends the first configuration information to the remote control module. The remote control module transmits the first scheduling information and the first configuration information to the satellite system 10.

Fig. 4 is a block diagram of software applications in the satellite system 10 according to an embodiment of the present application, and referring to fig. 4, the satellite system 10 includes applications 0 to m. In addition, the satellite system 10 includes scheduling applications, telemetry applications, bus management applications, and data transmission management applications. Wherein the satellite system 10 may establish a remote control channel with a remote control module of the ground system 20 via a remote control application and may also establish a telemetry channel with a telemetry module of the ground system 20 via a telemetry application. For example, the staff sends the first scheduling information for obtaining the telemetry packets of the plurality of objects to the remote control application in the satellite system 10 through the remote control module of the measurement and control system in the ground system 20. And the remote control application sends the first scheduling information of the plurality of objects to the scheduling application. And the scheduling application carries out conventional telemetry according to the scheduling period indicated by the first scheduling information, and periodically sends a request for acquiring the telemetry packets of the multiple objects to the applications 0-m. And responding to the request for acquiring the telemetry packets of the plurality of objects by the application 0-application m, detecting, generating a conventional telemetry packet (namely a first telemetry packet) according to a detection result, and transmitting the conventional telemetry packet to the telemetry application. The telemetry application generates a corresponding conventional telemetry frame (i.e., a second telemetry frame) from the conventional telemetry packet. The telemetry application transmits conventional telemetry frames in real time over a telemetry channel to a telemetry module in the surface system 20. The worker may receive conventional telemetry frames transmitted by the telemetry module in real time through the user interface.

Further, for example, the staff member transmits the first configuration information of the telemetry packet for acquiring the target object to the remote control application in the satellite system 10 through the remote control module in the ground system 20 so as to periodically acquire the telemetry data of the target object. The target object can be, for example, an application 0 in applications 0 to m, or a certain satellite-borne device in a plurality of satellite-borne devices. The remote control application sends the first configuration information of the telemetry packet of the acquired target object to the scheduling application. The scheduling application periodically sends a request to the telemetry application to obtain a telemetry package for the target object according to the first configuration information. The telemetry application responds to the request to obtain the telemetry packet for the target object and generates a configuration telemetry packet (i.e., a second telemetry packet) from the conventional telemetry packet. Wherein the configuration telemetry packet is a telemetry packet transmitted by the target object indicated by the first configuration information to the telemetry application. The telemetry application then generates a configuration telemetry frame (i.e., a first telemetry frame) from the second telemetry packet. The telemetry application transmits the configuration telemetry frame to a telemetry module in the surface system 20 via a telemetry channel. The configuration telemetry frame transmitted by the telemetry module may be received by the worker through the user interface.

In the operating environment described above, according to a first aspect of the present embodiment, a method for telemetry based on configuration information is provided, which is implemented by a processor shown in fig. 2A. Fig. 5 shows a flow diagram of the method, which, with reference to fig. 5, comprises:

s502: triggering a plurality of objects to generate a first telemetry package according to first scheduling information deployed on the satellite system, wherein the first scheduling information is used for indicating a scheduling period of conventional telemetry of the plurality of objects on the satellite system;

s504: extracting a second telemetry packet corresponding to the target object from the first telemetry packet according to first configuration information deployed in the satellite system, wherein the first configuration information is used for indicating the target object selected from the plurality of objects;

s506: generating a corresponding first telemetry frame from the second telemetry packet; and

s508: the first telemetry frame is downlink to the surface system.

Specifically, fig. 6 is a flowchart of a method for transmitting configuration telemetry frames (i.e., first telemetry frames) from the satellite system 10 to the ground system 20 in real time according to an embodiment of the present application; fig. 7 is a flowchart of a method for a satellite system 10 to delay sending configuration telemetry frames to a surface system 20 according to an embodiment of the present application, and fig. 8 is a diagram of a telemetry application generating configuration telemetry frames from conventional telemetry packets according to an embodiment of the present application.

Referring to fig. 3 to 8, after receiving first scheduling information, which is transmitted by a worker through a user interface and acquires conventional telemetry packets corresponding to a plurality of objects, a conventional measurement and control unit in the ground system 20 sends the first scheduling information to a remote control application in the satellite system 10 through a remote control module. So that the first scheduling information is deployed to the satellite system 10. In addition, after receiving the first configuration information transmitted by the staff through the user interface, the configuration measurement and control unit in the ground system 20 sends the first configuration information to the remote control application in the satellite system 10 through the remote control module. Such that the first configuration information is deployed to the satellite system 10.

Thus, the scheduling application triggers the plurality of objects to generate the normal telemetry packet (i.e., the first telemetry packet) according to the scheduling period indicated by the first scheduling information, based on the first scheduling information deployed on the satellite system 10 (S502). Wherein the first scheduling information is used to indicate a scheduling period for conventional telemetry of a plurality of objects on the satellite system 10. Specifically, the scheduling application periodically sends a request for obtaining the conventional telemetry packet to the plurality of objects according to a scheduling period for performing conventional telemetry on the plurality of objects in the first scheduling information. The plurality of objects detect in response to a request sent by the scheduling application to retrieve a conventional telemetry packet, generate a conventional telemetry packet, and then send the conventional telemetry packet to the telemetry application. For example, the scheduling period for conventional telemetry of the plurality of objects indicated in the first scheduling information is 1s, and the plurality of objects on the satellite system 10 may include, for example, a plurality of applications such as a time management application, a health monitoring application, and a thermal control management application, and a plurality of on-board devices such as a GNSS module. The scheduling application periodically sends a request for acquiring a conventional telemetry packet to objects such as a time management application, a health monitoring application, a thermal control management application and the like every 1s. Then, objects such as the time management application, the health monitoring application and the thermal control management application respond to a request sent by the scheduling application for acquiring the conventional telemetry packet, detect the request and generate the conventional telemetry packet. And finally, the objects such as the time management application, the health monitoring application, the thermal control management application and the like respectively send the generated conventional telemetry package to the telemetry application.

Table 1 shows a schematic table of objects such as a time management application, a health monitoring application, and a thermal management application generating a conventional telemetry packet every 1s.

TABLE 1

Referring to table 1, in response to a request for acquiring a conventional telemetry packet sent by a scheduling application, an object such as a time management application, a health monitoring application, and a thermal control management application is in a range of 5; in 5.

In addition, the telemetry application extracts a configuration telemetry packet (i.e., a second telemetry packet) corresponding to the target object from the conventional telemetry packets according to the first configuration information deployed on the satellite system 10 (S504). Wherein the first configuration information is used to indicate a target object selected from a plurality of objects. For example, the conventional telemetry packet includes a conventional telemetry packet corresponding to a time management application, a conventional telemetry packet corresponding to a health monitoring application, a conventional telemetry packet corresponding to a thermal management application, and a conventional telemetry packet corresponding to a power management application. The target objects indicated in the first configuration information include a time management application and a thermal management application. And the telemetry application reads the information indicated in the first configuration information and extracts the configuration telemetry packet corresponding to the health monitoring application and the configuration telemetry packet corresponding to the thermal control management application from the conventional telemetry packet according to the information indicated in the first configuration information.

Table 2 shows a schematic table of a telemetry application extracting configuration telemetry packets corresponding to a target object from conventional telemetry packets.

TABLE 2

Referring to table 2, the telemetry application is 5:10: 00.50 (i.e., 5 hours, 10 minutes, 0 seconds, 500 milliseconds), the slave thermal management is applied at 5:10:00 extracts the configuration telemetry packet from the generated conventional telemetry packet. Telemetry application 5:10: 01.50 (i.e., 5 hours, 10 minutes, 1 second, 500 milliseconds), the slave thermal management is applied at 5:10:01, and extracting the configuration telemetry packet from the generated conventional telemetry packet. And, the telemetry application is 5:10: 02.50 (i.e., 5 hours, 10 minutes, 2 seconds, 500 milliseconds), the slave thermal management is applied at 5:10:02 extracts configuration telemetry packets from the generated conventional telemetry packets. And so on. As can be seen from the above, the telemetry application periodically extracts configuration telemetry packets from conventional telemetry packets corresponding to a plurality of objects. Preferably, configuring the telemetry packet is performed within the same scheduling period as a corresponding conventional telemetry packet.

Further, the first configuration information sent by the ground system 20 may be a configuration information table corresponding to the target object.

Table 3 shows a table of configuration information for retrieving a configuration telemetry package corresponding to a target object.

TABLE 3

Referring to table 3, it can be seen that the configuration telemetry packet acquisition requests of different target objects correspond to different sequence numbers, the different sequence numbers correspond to data stream numbers of the different target objects, and the meanings of the data stream numbers of the different target objects are different. For example, the data stream number of the target object with sequence number 1 is APP-SCH-0.020. The meaning of APP-SCH-0.020 is that the configuration telemetry packet request with the time management application is acquired, and the transmission frequency of the configuration telemetry packet request with the time management application is 1s.

Then, the telemetry application extracts a conventional telemetry packet corresponding to the target object from the conventional telemetry packet according to the configuration information table, and generates a configuration telemetry packet corresponding to the target object according to the extracted conventional telemetry packet. After the telemetry application generates configuration telemetry packets corresponding to different target objects, configuration telemetry packet output tables corresponding to the different target objects are generated.

Table 4 shows that the telemetry application generates a table of configuration telemetry packet outputs corresponding to different target objects.

TABLE 4

Referring to table 4, the configuration telemetry packets of different target objects correspond to different configuration telemetry packet serial numbers, the different configuration telemetry packet serial numbers correspond to data stream numbers of the configuration telemetry packets of different target objects, and the data stream numbers of the configuration telemetry packets of different target objects have different meanings. For example, the data stream number of the target object with the configuration telemetry packet number of 1 is APP-TM-0.020.APP-TM-0.020 means a configuration telemetry package corresponding to a time management application.

Further, the telemetry application generates a corresponding configuration telemetry frame (i.e., a first telemetry frame) from the configuration telemetry packet (S506).

Finally, the telemetry application downlinks the configuration telemetry frame to the surface system 20 (S508). Specifically, the telemetry application downlinks the configuration telemetry frames to a telemetry module in the surface system 20 over a telemetry channel. And after receiving the configuration telemetry frame, the telemetry module sends the configuration telemetry frame to a configuration measurement and control unit in the measurement and control module. The configuration measurement and control unit transmits the configuration telemetry frame (i.e., the telemetry data corresponding to the target object) to the staff through the user interface.

In the technical solution of the present disclosure, the telemetry application sends the configuration telemetry frame to the ground system 20, and the configuration telemetry frame is generated according to the configuration telemetry packet, which is periodically extracted from the conventional telemetry packet according to the first configuration information, so that the telemetry application in the satellite system 10 can continuously send the configuration telemetry frame corresponding to the target object to the ground system 20.

That is, in the technical solution of the present disclosure, in the process of performing the conventional telemetry and generating the conventional telemetry frame, the telemetry application extracts the conventional telemetry packet corresponding to the target object specified in the first configuration information from each object generation telemetry packet and generates a corresponding configuration telemetry packet, and then generates a corresponding configuration telemetry frame.

In turn, because the ground system 20 is able to directly receive the configuration telemetry frames corresponding to the target object sent by the telemetry application in the satellite system 10, the ground system 20 is able to directly send the configuration telemetry frames corresponding to the target object to the personnel. Such that the operator may periodically obtain telemetry data for the target object from the satellite system 10 by sending configuration information to the satellite system 10 only once. And because the technical scheme of the present disclosure is to extract the configuration telemetry packet corresponding to the target object from the conventional telemetry packet, the telemetry data of the target object can be returned to the surface system 20 in each scheduling period only by extracting in each scheduling period of the conventional telemetry.

Therefore, the technical scheme of the disclosure achieves the technical effects that the staff can directly acquire the telemetering data of the target object transmitted by the satellite system 10 and simplify the operation process of acquiring the telemetering data of the target object. Further, the problem that telemetry data of target applications and/or target devices cannot be provided when conventional telemetry is used for sending telemetry data of a plurality of objects to the ground system 20 in the prior art is solved; when transmitting the telemetry data of the target application and/or the target device to the ground system 20 by using the query telemetry, the ground system 20 needs to continuously transmit the query command to the satellite system 10, and thus the operation process is complicated.

Optionally, the operation of generating a corresponding first telemetry frame from the second telemetry packet comprises: extracting third telemetry packets corresponding to different target objects from the second telemetry packet respectively; and generating a first telemetry frame corresponding to a different target object from the third telemetry packet.

Specifically, referring to fig. 6 and 7, in the process of generating a configuration telemetry frame (i.e., a first telemetry frame) from a configuration telemetry packet (i.e., a second telemetry packet), the telemetry application periodically scans the configuration telemetry packet and extracts a configuration telemetry packet (i.e., a third telemetry packet) corresponding to a different target object that meets scheduling requirements from the configuration telemetry packet. For ease of description, configuration telemetry packets extracted from conventional telemetry packets will be referred to herein as first configuration telemetry packets (i.e., second telemetry packets), and configuration telemetry packets extracted from first configuration telemetry packets corresponding to different target objects will be referred to herein as second configuration telemetry packets (i.e., third telemetry packets). Thus, the telemetry application generates second configuration telemetry frames corresponding to different target objects from the first configuration telemetry packet extracted from the conventional telemetry packet.

For example, the period for the telemetry application to scan for the first configuration telemetry packet is 10ms, and the first configuration telemetry packet includes a configuration telemetry packet corresponding to the time management application, a configuration telemetry packet corresponding to the health monitoring application, and a configuration telemetry packet corresponding to the thermal management application. And among the plurality of first configuration telemetry packets, only the configuration telemetry packet corresponding to the time management application and the configuration telemetry packet corresponding to the health monitoring application satisfy the scheduling requirement. Thus, the telemetry application first extracts the second configuration telemetry packet (i.e., the third telemetry packet) corresponding to the time management application, and after a 10ms interval, extracts the second configuration telemetry packet (i.e., the third telemetry packet) corresponding to the health monitoring application. Then, the telemetering application adds a frame head and a frame tail to a second configuration telemetering packet corresponding to the time management application to generate a configuration telemetering frame corresponding to the time management application; and the telemetry application adds a frame head and a frame tail to a second configuration telemetry packet corresponding to the health monitoring application to generate a configuration telemetry frame corresponding to the health monitoring application.

Thus, by extracting the operation for the second configuration telemetry packet from the telemetry packet, a technical effect is achieved that provides a necessary basis for generating the configuration telemetry frame corresponding to the second configuration telemetry packet.

Furthermore, the above is merely exemplary to illustrate the case where the number of second configuration telemetry packets (i.e., third telemetry packets) that satisfy the scheduling requirements is less than the number of first configuration telemetry packets (i.e., second telemetry packets) extracted from the regular telemetry packets. It should be apparent to those skilled in the art that the number of second configuration telemetry packets that meet scheduling requirements may be the same as the number of first configuration telemetry packets extracted from conventional telemetry packets.

Further, the above is only an exemplary description, and the configuration telemetry packet corresponding to the time management application is extracted first, and then the configuration telemetry packet corresponding to the thermal control management application is extracted. However, it should be clear to those skilled in the art that the order in which the telemetry application extracts configuration telemetry packets corresponding to different target objects is not limited.

Optionally, the method further comprises: a second telemetry frame is generated from the first telemetry packet and input to the first frame queue for real-time transmission.

Specifically, referring to fig. 6 and 7, first, in a conventional telemetry process, a telemetry application receives a conventional telemetry packet (i.e., a first telemetry packet) transmitted by a plurality of objects. The telemetry application then adds the conventional telemetry packet to the header and trailer and generates a conventional telemetry frame (i.e., a second telemetry frame). Finally, the telemetry application inputs the regular telemetry frames into a regular frame queue (i.e., the first frame queue) for real-time transmission. Wherein conventional telemetry frames input to the conventional frame queue can be transmitted to the surface system 20 in real time.

Thus, the technical effect of transmitting telemetry data of a plurality of objects to the surface system 20 in real time through conventional telemetry is achieved through the above operation.

Optionally, the operation of downlink the first telemetry frame to the surface system comprises: inputting the first telemetry frame to a second frame queue for real-time transmission; and real-time scheduling the first frame queue and the second frame queue to form a telemetering downlink frame queue for downlink.

Specifically, fig. 9 is a data flow diagram of a telemetry frame (i.e., a first telemetry frame) configured downstream by a telemetry application according to an embodiment of the present application. Referring to fig. 6 and 9, first, after the telemetry application generates configuration telemetry frames corresponding to different target objects from the second configuration telemetry packet (i.e., the third telemetry packet), the configuration telemetry frames are input to a configuration frame queue for real-time transmission (i.e., the second frame queue). Wherein configuration telemetry frames input to the configuration frame queue can be transmitted to the surface system 20 in real time.

The telemetry application then schedules the regular and configuration frame queues in real-time in response to the trigger information sent by the scheduling application. Namely, the conventional frame queue and the configuration frame queue are combined into a telemetry downlink frame queue. Wherein, the telemetry downlink frame queue comprises configuration telemetry frames (namely, first telemetry frames) and conventional telemetry frames (namely, second telemetry frames). The period for the scheduling application to send the trigger information may be, for example, 1s, and may be adjusted according to the downlink rate of the telemetry frame. And wherein the configuration telemetry frames in the configuration frame queue correspond to portions of the telemetry frames of the regular telemetry frames in the regular frame queue, as the regular frame queue and the configuration frame queue are both queues for real-time transmission.

Finally, the telemetry application takes frames downstream from the telemetry downstream frame queue and transmits the conventional telemetry frames and the configured telemetry frames to the surface system 20 in real time.

For example, the regular frame queue includes regular telemetry frames corresponding to objects such as time management applications, health monitoring applications, and thermal management applications. When the target object indicated by the first configuration information is a time management application and a thermal control management application, the telemetry application inputs a configuration telemetry frame corresponding to the time management application and a configuration telemetry frame corresponding to the thermal control management application into a configuration frame queue for real-time transmission.

Then, the telemetry application responds to the trigger information sent by the scheduling application, and carries out real-time scheduling on a conventional frame queue containing conventional telemetry frames corresponding to objects such as a time management application, a health monitoring application and a thermal control management application, and a configuration frame queue containing configuration telemetry frames corresponding to the time management application and configuration telemetry frames corresponding to the thermal control management application. Thus, a telemetry downlink frame queue for downlink is composed.

Finally, the conventional telemetry frame corresponding to the objects such as the time management application, the health monitoring application, the thermal control management application and the like in the telemetry downlink frame queue and the configuration telemetry frame corresponding to the time management application are downlink to the ground system 20 in real time.

Therefore, the technical effect of being capable of descending the telemetering data of a plurality of target objects and the telemetering data of a target object in the plurality of objects to the surface systems and 20 in real time together is achieved through the operation.

Optionally, the operation of downlink the first telemetry frame to the surface system comprises: storing the first telemetry frame to a preset storage file; responding to trigger information for descending a first telemetry frame, and acquiring the first telemetry frame from a storage file; inputting the acquired first telemetry frame into a third frame queue; and real-time scheduling the third frame queue and the first frame queue to form a telemetering downlink frame queue for downlink.

Specifically, referring to fig. 7 and 9, in the process of sending the configuration telemetry frame down to the surface system 20, first, the telemetry application queries whether there is a configuration telemetry frame in the configuration frame queue. And under the condition that the configuration frame queue has the configuration telemetry frame, the telemetry application acquires the configuration telemetry frame in the configuration frame queue and writes the configuration telemetry frame into a storage file. The storage form of the storage file comprises platform storage and load storage.

The telemetry application then reads the configuration telemetry frame from the memory file for the entire frame in response to the trigger information sent by the scheduling application. The period of sending the trigger information by the scheduling application is 1s, and the scheduling application can adjust the period according to the downlink rate of the telemetry frame.

Then, the telemetry application acquires the configuration telemetry frame previously stored in the storage file from the storage file, and since the configuration telemetry frame at this time is delayed in the downlink with respect to the time at which the configuration telemetry frame is generated, it is input to a delay frame queue (i.e., a third frame queue) for delayed downlink.

And then the telemetry application carries out real-time scheduling on the telemetry frames in the delay frame queue and the current conventional frame queue to form a telemetry downlink frame queue for downlink. Notably, since the configuration telemetry frames are stored in the memory file for a certain time in advance, the configuration telemetry frames read by the telemetry application do not correspond to the telemetry frames in the regular frame queue. For example, the regular telemetry frames in the current regular frame queue are generated with a scheduling period that is later than the scheduling period for generating the configuration telemetry frames.

Finally, the telemetry application takes frames downstream from the telemetry downstream frames, and transmits the configured telemetry frames and the conventional telemetry frames in the conventional frame queue to the surface system 20 in real time.

For example, the regular frame queue includes regular telemetry frames corresponding to objects such as a time management application, a health monitoring application, and a thermal management application. The target object indicated by the first configuration information is a time management application and a thermal control management application. And the telemetry application stores the configuration telemetry frame corresponding to the time management application and the telemetry frame corresponding to the thermal control management application to a preset storage file.

Then, the telemetry application responds to the trigger information sent by the scheduling application, and acquires a configuration telemetry frame corresponding to the time management application from the storage file. In addition, the telemetry application inputs the acquired configuration telemetry frame corresponding to the time management application and the configuration telemetry frame corresponding to the thermal control management application into the delay frame queue, and real-time scheduling is carried out on the current conventional telemetry frame corresponding to the objects of the time management application, the health monitoring application, the thermal control management application and the like contained in the conventional frame queue. Thus, a telemetry downlink frame queue for downlink is composed.

Finally, the configuration telemetry frame corresponding to the time management application, the configuration telemetry frame corresponding to the thermal control management application, and the current conventional telemetry frame corresponding to the objects such as the time management application, the health monitoring application, the thermal control management application, and the like in the telemetry downlink frame queue are downlink to the ground system 20 in real time.

Therefore, through the above operation, even when the number of the remote measurement data of the target object needs to be acquired by the worker, the remote measurement data of the target object can be transmitted to the ground system 20 in batch.

Optionally, the operation of storing the first telemetry frame in a preset storage file includes: determining whether the first telemetry frame is a full frame; and storing the first telemetry frame to a storage file if the first telemetry frame is a full frame.

In particular, fig. 10 is a diagram illustrating a telemetry application storing a configuration telemetry frame (i.e., a first telemetry frame) in a storage file according to an embodiment of the present application. Referring to fig. 6, 7 and 10, the telemetry application maintains a state of waiting for the trigger information when the trigger information transmitted by the scheduling application is not received. After the telemetry application receives the trigger information sent by the scheduling application, it responds to the trigger information and determines whether the configured telemetry frame is a full frame. In the event that the configuration telemetry frame is a full frame, the telemetry application stores the configuration telemetry frame to a storage file. In the event that the configuration telemetry frame is not a full frame, the telemetry application re-waits to receive the trigger information sent by the scheduling application.

Therefore, the technical effect that the configuration telemetry frame can be stored in the storage file under the condition that the configuration telemetry frame is full is achieved through the operation, so that more configuration telemetry packets can be combined in the same configuration telemetry frame, and a necessary basis is provided for transmitting the telemetry data of the target object to the ground system 20 in batches.

Optionally, the operation of generating a first telemetry frame corresponding to a different target object from the third telemetry packet comprises: determining whether the third telemetry packet is permitted to downlink; in the event that the third telemetry packet permits downlink, a first telemetry frame corresponding to a different target object is generated from the third telemetry packet.

Specifically, referring to fig. 6, 7 and 9, when the trigger information transmitted by the scheduling application is not received, the telemetry application remains in a state of waiting for the trigger information. The telemetry application, upon receiving the trigger information sent by the scheduling application, generates a first configuration telemetry packet (i.e., a second telemetry packet) in response to the trigger information. The telemetry application then extracts a second configuration telemetry packet (i.e., a third telemetry packet) from the first configuration telemetry packet that meets the scheduling requirements and determines whether the second configuration telemetry packet is permitted to downlink to the surface system 20. Under the condition that the second configuration telemetry packet permits downlink, the telemetry application adds a frame head and a frame tail to the second configuration telemetry packet to generate a configuration telemetry frame; in the event that the second configuration telemetry packet is prohibited from descending, the telemetry application re-waits to receive the trigger information sent by the scheduling application.

Therefore, by determining in advance whether the second configuration telemetry packet is permitted to downlink to the ground system 20, and generating a corresponding configuration telemetry frame under the condition that the second configuration telemetry packet is permitted to downlink, the technical effects of simplifying the framing process and avoiding wasting resources are achieved.

Optionally, the plurality of objects includes a plurality of applications and a plurality of devices, and the first telemetry package includes a fourth telemetry package corresponding to the plurality of applications and/or a fifth telemetry package corresponding to the plurality of devices, and the operation of the plurality of objects to generate the first telemetry package is triggered according to the first scheduling information deployed in the satellite system, including: sending a request for acquiring a fourth remote test packet to a plurality of applications according to the scheduling period in the first scheduling information; and generating a fourth telemetry packet in response to the request to acquire the fourth telemetry packet.

Specifically, referring to fig. 6 or 7, a plurality of objects requiring conventional telemetry are provided in the satellite system 10. Wherein the plurality of objects comprises a plurality of applications and/or a plurality of devices.

In the normal telemetry process, first, the scheduling application periodically sends a request for acquiring a normal application telemetry packet (i.e., a fourth telemetry packet) to the plurality of applications according to a scheduling period for normal telemetry of the plurality of applications indicated by the first scheduling information. And the plurality of applications respond to the request for acquiring the conventional application telemetry packet sent by the scheduling application, perform detection and generate the conventional application telemetry packet according to the detection result.

For example, the scheduling period indicated by the first scheduling information for conventional telemetry of the plurality of applications in the satellite system 10 is 1s. The plurality of applications in the satellite system 10 include time management applications, health monitoring applications, and thermal management applications.

And the scheduling application sends a request for acquiring the conventional application telemetry packet to the time management application, the health monitoring application, the thermal control management application and other applications at intervals of 1s according to the scheduling period for performing conventional telemetry on the time management application, the health monitoring application, the thermal control management application and other applications indicated by the first scheduling information. The time management application, the health monitoring application, the thermal control management application and other applications respond to a request for acquiring the conventional application telemetry package sent by the scheduling application, respectively detect the request, and respectively generate the conventional application telemetry packages corresponding to the time management application, the health monitoring application, the thermal control management application and other applications according to the detection result.

Furthermore, it should be apparent to those skilled in the art that the number of objects in the satellite system 10 that require conventional telemetry may be greater than or equal to the number of applications. That is, the plurality of objects may include a plurality of applications and a plurality of devices, or may include only a plurality of applications. In the case where the plurality of objects includes only a plurality of applications, the number of conventional telemetry packets is the same as the number of conventional application telemetry packets.

Therefore, the technical effect of generating the conventional application telemetry package corresponding to the plurality of applications is achieved through the operation.

Optionally, triggering the plurality of objects to generate the first telemetry package according to the first scheduling information deployed in the satellite system, including: sending a request for acquiring a fifth telemetry packet to the bus management application according to the scheduling period in the first scheduling information; sending a request to obtain a fifth telemetry packet to the plurality of devices; and generating a fifth telemetry packet in response to the get fifth telemetry packet request.

Specifically, referring to fig. 6 or fig. 7, first, the scheduling application periodically sends a request for obtaining a regular device telemetry packet (i.e., a fifth telemetry packet) to the bus management application according to a scheduling cycle for regular telemetry of the plurality of devices indicated by the first scheduling information. The bus management application sends a request to the plurality of devices to obtain a conventional device telemetry packet. And the plurality of devices respond to a request for acquiring the conventional device telemetry packet sent by the scheduling application, perform detection and generate the conventional device telemetry packet according to the detection result.

For example, the scheduling period indicated by the first scheduling information for conventional telemetry of the plurality of devices in the satellite system 10 is 1s. The plurality of devices in the satellite system 10 include a GNSS module, a fiber optic gyroscope, a high-moment flywheel, and the like.

And the scheduling application sends a request for acquiring a telemetry packet of the conventional equipment to the bus management application every 1s according to a scheduling period for performing conventional telemetry on the equipment such as the GNSS module, the optical fiber gyroscope, the large-torque flywheel and the like indicated by the first scheduling information. The bus management application periodically sends a request for obtaining a conventional device telemetry package to devices such as a GNSS module, an optical fiber gyroscope, a high-torque flywheel and the like. The GNSS module, the optical fiber gyroscope, the large-moment flywheel and other devices respond to a request sent by the scheduling application for acquiring the telemetry packet of the conventional device, respectively detect the requests, and respectively generate the telemetry packet of the conventional device corresponding to the GNSS module, the optical fiber gyroscope, the large-moment flywheel and other devices according to the detection result.

Therefore, the technical effect of generating the conventional device telemetry packet corresponding to the plurality of devices is achieved through the operation.

Optionally, the method further comprises: receiving second scheduling information and second configuration information from the ground system; and updating the first scheduling information and the first configuration information according to the second scheduling information and the second configuration information.

Specifically, fig. 11 is a schematic data flow diagram of a telemetry application for acquiring a second telemetry packet in response to a scheduling application according to an embodiment of the present disclosure, and fig. 12 is a schematic flow diagram of a method for a terrestrial system 20 to transmit second scheduling information and second configuration information to a satellite system 10 according to an embodiment of the present disclosure. Referring to fig. 11 and 12, first, the measurement and control module in the ground system 20 transmits the received second scheduling information and second configuration information to the remote control module. The second scheduling information is scheduling information different from the first scheduling information, and the second configuration information is configuration information different from the first configuration information. For example, the scheduling period for conventional telemetry of a plurality of objects on the satellite system 10 indicated by the first scheduling information is 1s. The scheduling period for conventional telemetry of the plurality of objects on the satellite system 10 indicated by the second scheduling information is 2s. The target object of the plurality of objects indicated by the first configuration information is a time management application and a GNSS module. The target object in the plurality of objects indicated by the second configuration information is a time management application and a measurement and control unit.

The remote control module in the ground system 20 then transmits the second scheduling information and the second configuration information to the remote control application on the satellite system 10 through the remote control channel. And the remote control application transmits the received second scheduling information and second configuration information to the scheduling application.

Further, after receiving the second scheduling information and the second configuration information, the scheduling application updates the original first scheduling information and the original first configuration information inside. That is, the internal first scheduling information is replaced with the second scheduling information and the internal first configuration information is replaced with the second configuration information.

Finally, the scheduling application transmits the second scheduling information and the second configuration information to the telemetry application. And after receiving the second scheduling information and the second configuration information, the telemetering application updates the original first scheduling information and the original first configuration information in the telemetering application. That is, the internal first scheduling information is replaced with the second scheduling information and the internal first configuration information is replaced with the second configuration information.

Therefore, through the operation, the technical effect of timely updating the scheduling period required for performing the conventional telemetry on the plurality of objects and the target object in the plurality of objects can be achieved.

In the technical scheme of the disclosure, the telemetry application carries out conventional telemetry and sends the configuration telemetry frame to the ground system, the configuration telemetry frame is generated according to the configuration telemetry packet, and the configuration telemetry packet is periodically extracted from the conventional telemetry packet according to the first configuration information, so that the telemetry application in the satellite system can continuously send the configuration telemetry frame corresponding to the target object to the ground system. That is, in the technical solution of the present disclosure, in the process of performing the normal telemetry and generating the normal telemetry frame, the telemetry application extracts the configuration telemetry packet corresponding to the target object specified in the first configuration information from the respective object generation telemetry packets and generates the corresponding configuration telemetry frame. And the ground system can directly receive the configuration telemetry frame corresponding to the target object, which is sent by the telemetry application in the satellite system, so that the ground system can directly send the configuration telemetry frame corresponding to the target object to the staff. Therefore, the staff can periodically acquire the telemetering data of the target object from the satellite system only by sending the configuration information to the satellite system once. And because the technical scheme of the disclosure is to extract the configuration telemetry packet corresponding to the target object from the conventional telemetry packet, the telemetry data of the target object can be returned to the ground system in each scheduling period only by extracting in each scheduling period of the conventional telemetry. Therefore, the technical scheme of the disclosure achieves the technical effects that the working personnel can directly acquire the telemetering data of the target object transmitted by the satellite system, and the operation process of acquiring the telemetering data of the target object is simplified. Further, the problem that telemetry data of a plurality of objects cannot be provided when conventional telemetry is used for sending the telemetry data of the objects to a ground system in the prior art is solved; before sending the telemetering data of the target application and/or the target equipment to the ground system by using the inquiry telemetering, the ground system needs to continuously send an inquiry instruction to the satellite system, so the technical problem of complicated operation process is solved.

s1372: and the telemetry application stores the configuration telemetry frame into a preset storage file, acquires the configuration telemetry frame from the storage file and inputs the acquired configuration telemetry frame into a delay frame queue. And scheduling the delay frame queue and the conventional frame queue in real time to form a telemetry downlink frame queue for downlink, and then downlink the configuration telemetry frame and the conventional telemetry frame in the telemetry downlink frame queue to the ground system 20.

Further, referring to fig. 2A and 2B, according to a second aspect of the present embodiment, there is provided a storage medium. The storage medium comprises a stored program, wherein the method of any of the above is performed by a processor when the program is run.

Further, the problem that telemetry data of a target application and/or a target device cannot be provided when telemetry data of a plurality of objects is sent to the ground system 20 by using conventional telemetry in the prior art is solved; before sending the telemetry data of the target application and/or the target device to the ground system 20 by using query telemetry, the ground system 20 needs to continuously send query instructions to the satellite system 10, so that the operation process is complicated.
