Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method and device for indirect transmission and comparison of spacecraft injection data. Background Art

[0002] The control modes of spacecraft are complex. During the multi-target collaboration process, the spacecraft measurement and control link may be blocked by other spacecraft, making it impossible to issue direct commands to them. Therefore, the ground control center needs to implement uplink control through indirect transmission of commands.

[0003] The control method in which the ground control center forwards the uplink control data of the control target spacecraft (referred to as the control target) through the proxy routing spacecraft (referred to as the proxy routing) is called indirect proxy control. When implementing indirect proxy control, the ground control center sends uplink control data to the control target through the measurement and control link of the proxy routing.

[0004] The ground control center is responsible for framing the injection chain according to the injection format requirements of the routing number tube, and the ground control center implements the injection.

[0005] The ground control center can send injection chains to the control target by indirect transmission through different forward channels of ground stations and relays. Different injection chains need to be sent in different uplink modes, and then the injection chain indirect transmission comparison and judgment are performed through the real-time telemetry data returned by the spacecraft. However, the existing transmission routing technology needs to forward the injection data to the control target only after the injection chain is executed. It is suitable for injection chains that only send injection data. For some types of injection chains, it is impossible to obtain sufficient telemetry data within the comparison time, which makes the comparison result calculation inaccurate.

[0048] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily.

[0049] Figure 1 FIG. 1 is a flow chart of a method for indirect transmission and judgment of spacecraft injection data provided by an embodiment of the present invention. Figure 1 As shown, an indirect transmission comparison and judgment method for spacecraft injection data provided by an embodiment of the present invention is performed through a transmission comparison and judgment process and a control target comparison and judgment process, and the indirect transmission comparison and judgment method for spacecraft injection data includes:

[0050] Step S1: determining the injection chain type through the proxy comparison process, and determining the generation time of the virtual comparison application according to whether the injection chain corresponding to the injection chain type contains the result of sending the user instruction.

[0051] Step S2: calling the virtual comparison application at the generation time through the control target comparison process, and generating a corresponding self-comparison application.

[0052] Step S3: Calculate the start time of the injection link corresponding to the injection chain type in the message queue of the control target comparison process by using the uplink delay of the proxy routing, the downlink delay of the control target and the generation time.

[0053] Step S4: Calculate the comparison time of the injection chain corresponding to the injection chain type according to the preset comparison cycle number and the preset current telemetry mode frame cycle through the control target comparison process, receive telemetry data within the comparison time, and obtain the comparison result of the injection chain according to the telemetry data.

[0054] In the above step S1, the device determines the injection chain type through the proxy comparison and judgment process, and determines the generation time of the virtual comparison and judgment application according to whether the injection chain corresponding to the injection chain type contains the result of sending the user instruction. The device can be a computer device that executes the method, for example, it can include a management device of a ground control center. The proxy comparison and judgment process and the control target comparison and judgment process are both processes in the management device, and respectively execute the indirect proxy comparison and judgment method of spacecraft injection data.

[0055] Determining the injection chain type through the transmission comparison process may include: if the injection chain does not contain a send user instruction, determining the injection chain type to be the first injection chain type, corresponding to injection chain A, applicable to relay link A, using CCSDSAOS format, and the first injection chain type only contains one item of injection data; wherein CCSDS AOS is a common professional term in the field of aviation flight.

[0056] Determining the injection chain type through the said transmission comparison process may include: if the injection chain includes sending user instructions, then determining the injection chain type as the second injection chain type, corresponding to injection chain B, suitable for relay link B, using PCM remote control format, the second injection chain type includes remote control door opening, data injection, remote control door closing and sending user instructions; wherein PCM is a common professional term in the field of aviation flight.

[0057] The step of determining the generation time of the virtual comparison application according to whether the injection chain corresponding to the injection chain type contains the result of sending the user instruction comprises:

[0058] The time at which the injection data in the injection chain corresponding to the first injection chain type is sent is used as the time at which the virtual comparison application is generated. Figure 2 As shown, T0g is the time when the injected data is sent.

[0059] The step of determining the generation time of the virtual comparison application according to whether the injection chain corresponding to the injection chain type contains the result of sending the user instruction comprises:

[0060] The time at which the user instruction is sent in the injection chain corresponding to the second injection chain type is used as the time at which the virtual comparison application is generated. Figure 3 As shown, T3 is the time when the user instruction is sent.

[0061] In the above step S2, the device calls the virtual comparison application at the generation time through the control target comparison process, and generates a corresponding self-comparison application. That is, the target comparison process calls the virtual comparison application generated in the proxy comparison process, and generates a corresponding self-comparison application in the target comparison process.

[0062] In the above step S3, the device calculates the start judgment time of the injection link corresponding to the injection link type in the message queue of the control target judgment process by using the uplink delay of the proxy routing, the downlink delay of the control target and the generation time. The uplink delay and the downlink delay can be obtained in advance.

[0063] The uplink delay of the proxy routing, the downlink delay of the control target and the generation time are used to calculate the start judgment time of the injection chain corresponding to the injection chain type in the message queue of the control target comparison process, including:

[0064] The generation time of the virtual comparison application corresponding to the first injection chain type and the second injection chain type respectively, and the sum of the injection chain delays are used as the start judgment time of the injection chain corresponding to the injection chain type; wherein the injection chain delay sum is the sum of the uplink delay and the downlink delay.

[0065] Reference Figure 2 , the injection chain A start judgment time Tqg = injection data sending time T0g + injection chain delay sum ΔTs.

[0066] Reference Figure 3 , the injection chain B start judgment time Tqs = the user instruction sending time T3 + injection chain delay and ΔTs.

[0067] In the above step S4, the device calculates the comparison time of the injection chain corresponding to the injection chain type according to the preset comparison cycle number and the preset current telemetry mode frame cycle through the control target comparison process, receives telemetry data within the comparison time, and obtains the comparison result of the injection chain according to the telemetry data. The comparison is described as follows:

[0068] The execution results of the injection chain are judged according to the design binding criteria through the real-time telemetry data returned by the spacecraft.

The preset comparison and judgment cycle number can be set independently according to actual conditions, and can be selected as 24 cycles.

[0071] The preset current telemetry mode frame period can be set independently according to actual conditions and can be selected as 512ms.
