[0003] For traditional patrollers, there are only two storage areas: telemetry data storage area and image data storage area, which are independent of each other and have simple storage logic.

The current storage status is obtained from real-time telemetry for verification to support subsequent planning tasks.

[0004] However, the patroller has a large number of storage areas, the data storage logic is complex, there are associations between the storage areas, and the workload of maintaining the storage status is large. Summary of the invention

[0046] 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.

[0047] Figure 1 FIG. 1 is a flow chart of a method for determining a data storage state of a patroller provided by an embodiment of the present invention. Figure 1 As shown, the data storage status determination method of the patroller provided by the embodiment of the present invention includes:

[0048] Step S1: input storage event related data into the storage event model, and add the corresponding storage events to the corresponding event queue through the storage event model; the storage event model includes the original image storage event model, the compressed image storage event model and the delayed telemetry storage event model.

[0049] Step S2: Process the storage events in each event queue in turn through each storage event model to obtain the calculation result of the data storage state.

[0050] Step S3: Evaluate the execution result of the storage event according to the downlink delayed telemetry data, and correct the calculation result of the data storage state of the storage event that is not correctly executed.

[0051] In the above step S1, the device inputs the storage event related data into the storage event model, and adds the corresponding storage events to the corresponding event queues through the storage event model; the storage event model includes the original image storage event model, the compressed image storage event model and the delayed telemetry storage event model. The device can be a computer device that executes the method, such as a control center server, which can obtain the storage event related data and download the delayed telemetry data and other data required to execute the method. The method of the embodiment of the present invention can simulate the data storage state of the data stored in the rover, and the rover can include an external celestial body rover.

[0052] It is necessary to establish a storage event model in advance, where the storage event model for the original image is:

[0053] Four types of cameras can be installed on the patroller. After being driven by the imaging drive instruction, one or more cameras will start to generate several raw images, which are stored in the corresponding storage areas A1~A4 respectively. The raw image sizes are fixed values ​​S1~S4 (unit Mb). This model defines the generation of a single raw image as a raw image storage event. As shown in Table 1, an imaging drive instruction is usually accompanied by the occurrence of multiple raw image storage events.

[0054] Table 1

[0055]

[0056] The model elements included in the original image storage event model are not limited to the model elements in Table 1, and may also include model elements required by the original image storage event model to process storage events.

[0057] For compressed image storage event model:

[0058] After the image compression remote control injection data is input, the selected multiple images are compressed in sequence according to the numbering order from the specified original image storage area and stored in the compressed image storage area in the form of data frames. This model defines the compression storage of a single original image as a storage event, as shown in Table 2. An image compression instruction is usually accompanied by multiple compressed image storage events.

[0059] Table 2

[0060]

[0061] The model elements included in the compressed image storage event model are not limited to the model elements in Table 2, and may also include model elements required by the compressed image storage event model to process storage events.

[0062] For delayed telemetry storage event model:

[0063] In the patrol detection working state, the patroller writes delayed telemetry data to the three delayed telemetry storage areas at different frequencies; if a storage area stops writing, the storage frequency is considered to be 0. This model defines the remote control command execution related to telemetry mode switching and delayed telemetry storage cycle adjustment as a delayed telemetry storage event, as shown in Table 3.

[0064] Table 3

[0065]

[0066]

[0067] The model elements included in the delayed telemetry storage event model are not limited to the model elements in Table 3, and may also include model elements required for the delayed telemetry storage event model to process storage events.

[0068] The storage event related data can be obtained by receiving uplink remote control data. The storage event related data may include drive instructions and injection parameters related to the storage event, and the corresponding storage events are triggered in sequence; if one instruction corresponds to multiple events in multiple storage areas, they are triggered separately. The corresponding storage events can be triggered in the order of original image storage events, compressed image storage events, and delayed telemetry storage events.

[0069] The storage events are added to the corresponding event queues respectively, including adding the original image storage events to the original image storage event queues L1~L4, adding the compressed image storage events to the compressed image storage event queue L5, and adding the delayed telemetry storage events to the delayed telemetry storage event queues L6~L8.

[0070] In the above step S2, the device processes the storage events in each event queue in turn through each storage event model to obtain the calculation result of the data storage state.

[0071] The storage events in the original image storage event queue are processed by the original image storage event model; conventional processing methods in the art may be used.

[0072] The storage events in the compressed image storage event queue are processed by the compressed image storage event model to obtain the calculation result of the compressed image data storage state; specifically, the method includes:

[0073] The calculation result of the compressed image data storage status is calculated based on the original image size, the number of compressed image data frames corresponding to each single node pointed to by the address pointer, the amount of image data contained in each compressed image data frame, the number of bad blocks between the start address pointer and the record address pointer for executing the current compressed image storage, the number of node addresses corresponding to each bad block, and the compression ratio.

[0074] The number of compressed image data frames that can be stored in each single node pointed to by the address pointer can be set independently according to actual conditions, and can be selected as 4.

[0075] The amount of image data contained in each compressed image data frame is Len bytes. It should be noted that the 4 compressed image data frames of each node need to be fully written during storage. Therefore, when the compressed compressed image data frame is not an integer multiple of 4, 1 to 3 idle frames will be filled.

[0076] The calculation result of the compressed image data storage state is calculated according to the original image size, the number of compressed image data frames corresponding to each single node pointed to by the address pointer, the amount of image data contained in each compressed image data frame, the number of bad blocks between the start address pointer and the record address pointer for executing the current compressed image storage, the number of node addresses corresponding to each bad block, and the compression ratio, specifically including calculation according to the following formula:

[0077] W2=W1+ceil(ceil((Si / r)×1024×1024 / 8 / Len) / 4)+64×M

[0078] Among them, Si is the original image size (Mb), the function ceil(X) means returning the smallest integer greater than X, M is the number of bad blocks between W1 and W2, r is the compression ratio (specific description, as shown in Table 2), and the number of nodes corresponding to a single bad block can be set independently according to actual conditions, and can be selected as 64, which can be explained in Table 2. The W1 of the first event in queue L5 is the initial address W0 of the compressed storage area, and the W2 of the previous event is used as the W1 of the next event, and it is continuously iterated until the entire process of calculating the compressed image data storage state is completed.

[0079] Other model elements can be obtained from instruction information and injection parameters.

[0080] The storage events in the delayed telemetry storage event queue are processed by the delayed telemetry storage event model to obtain the calculation result of the delayed telemetry data storage state; specifically including:

[0081] Determine the count value of the telemetry storage frame, and calculate the result of the delayed telemetry data storage status according to the count value of the telemetry storage frame, the number of telemetry storage frames corresponding to each single node pointed to by the address pointer, the amount of telemetry data contained in each telemetry storage frame, the length of each telemetry storage frame, the number of bad blocks between the start address pointer and the record address pointer for executing the current delayed telemetry storage, and the number of node addresses corresponding to each bad block.

[0082] The number of telemetry storage frames that can be stored in each single node pointed to by the address pointer can be set independently according to actual conditions, and can be selected as 4.

[0083] The amount of image data contained in each telemetry storage frame is Ls bytes, and the length of each telemetry storage frame is Lf bytes.

[0084] Specifically, it is calculated according to the following formula:

[0085] w2=w1+ceil(N×Lf / Ls / 4)+64×m

[0086] Among them, N is the count value of the telemetry storage frame, the number of bad blocks between the start address pointer and the record address pointer for executing the current delayed telemetry storage is m, and the number of nodes corresponding to a single bad block can be set independently according to the actual situation, which can be selected as 64, as shown in Table 2. w1 and w2 are the start address pointer and record address pointer of the current delayed telemetry storage, respectively. w2 of the previous event is used as w1 of the next event, and it is continuously iterated until the entire process of calculating the delayed telemetry data storage state is completed.

[0087] If the delayed telemetry event queue meets T i <T end There are k storage events in total, then the deadline is T end The telemetry data frame count stored at this time is the count value of the telemetry storage frame.

[0088] The data storage state determination method further includes obtaining a delayed telemetry storage execution time, a delayed telemetry storage period, a preset deadline time, and the number of storage events in the delayed telemetry storage event queue; accordingly, determining the count value of the telemetry storage frame includes:

[0089] The count value of the telemetry storage frame is calculated according to the delayed telemetry storage execution time, the delayed telemetry storage cycle, the preset cut-off time and the number of storage events in the delayed telemetry storage event queue. The preset cut-off time can be set independently according to actual conditions. The count value N of the telemetry storage frame can be calculated according to the following formula:

[0090]

[0091] Among them, T k is the delayed telemetry storage execution time corresponding to the kth storage event, T i is the delayed telemetry storage execution time corresponding to the i-th storage event, T end is the preset cut-off time, P k is the delayed telemetry storage period corresponding to the kth storage event, P i is the delayed telemetry storage period corresponding to the i-th storage event.

[0092] In addition, if an erase instruction is encountered, the corresponding event queue is cleared, and the record address pointer of the compressed image and delayed telemetry storage area is restored to the initial address of the memory.

[0093] In the above step S3, the device evaluates the execution result of the storage event according to the downlink delayed telemetry data, and corrects the calculation result of the data storage state of the storage event that is not correctly executed.

[0094] like Figure 2 As shown, the evaluation of the execution result of the storage event according to the downlink delayed telemetry data includes:

[0095] S31: Determine the target parameters for evaluating the storage event according to the downlink delayed telemetry data, and determine the target parameter value range corresponding to the target parameters; if the target parameters for evaluating storage event a are A1 and B2, extract the target parameters A1 and B2 from the downlink delayed telemetry data, and storage event a can be one of the above-mentioned original image storage event, compressed image storage event and delayed telemetry storage event.

[0096] The target parameter value interval of A1 is (a11, a12), and the target parameter value interval of B2 is (b21, b22). The target parameter value interval is a parameter value interval corresponding to the correct execution of a predetermined storage event.

[0097] S32: Determine the evaluation result of the execution result of the storage event according to the comparison result of the target parameter and the target parameter value interval. If A1 and B2 are both in (a11, a12) and (b21, b22) respectively, then determine that the evaluation result is a correctly executed storage event.

[0098] The step of determining an evaluation result of the execution result of the storage event according to a comparison result between the target parameter and the target parameter value interval includes:

[0099] If it is determined that the target parameter is not within the target parameter value range, then the evaluation result is determined to be a storage event that is not executed correctly.

[0100] If at least one of A1 and B2 is not in (a11, a12) and / or (b21, b22), the evaluation result is determined to be a storage event that is not correctly executed.

[0101] The stored events in each event queue are evaluated one by one, and the evaluation results are recorded: "not correctly executed" or "correctly executed"; events that have been evaluated will not be evaluated again.

[0102] The correction processing of the calculation result of the data storage state of the storage event that is not correctly executed includes:

[0103] The storage event corresponding to the calculation result of the data storage state of the storage event that was not correctly executed is deleted, and the relevant data in the corresponding event queue is updated. If a certain original image storage event is not correctly executed, the storage event in the original image storage event queue is deleted, and the "image number" of the subsequent storage event in the original image storage event queue is recalculated. At the same time, the "compressed original image information" of the relevant storage event in the compressed image storage event queue is updated, and the address pointers W1, W2 and the number of bad blocks M are updated according to the calculation method of the compressed image data storage state.

[0104] If a compressed image storage event is not correctly executed, the storage event in the compressed image storage event queue is deleted, and the address pointers W1, W2 and the number of bad blocks M are updated according to the calculation method of the compressed image data storage state.

[0105] If a delayed telemetry storage event is not correctly executed, the storage event in the delayed telemetry storage event queue is deleted, and the address pointers w1, w2 and the number of bad blocks m are updated according to the calculation method of the delayed telemetry data storage state.
