1. An automatic generation method of a satellite-ground frame table of a PCM telemetry system (as shown in figure 2);

template definition: the telemetry frame comprises a frame head zone, a frame tail zone and a frame data zone, the frame data zone multiplexing mode in a certain telemetry mode is defined by the following table, and the frame data zone is divided into 1 frame/cycle, 4 frames/cycle, 16 frames/cycle, 32 frames/cycle and the like (in a 2-frame mode)ⁿDivided frame/period). Generating a framing basic unit: and processing and generating a basic framing unit (frame element for short) according to a provided telemetering packet cell organization structure table provided by the subsystem.

TABLE 1 certain telemetry mode frame structure template for PCM telemetry

Table 2 remote sensing packet cell organization table

According to the constraint condition of the whole byte, the telemetry packet is divided into a plurality of segments, each segment is an integer byte and comprises a plurality of telemetry cells. According to the same-framing constraint of the telemetering cell (namely, the downloading time of a plurality of cells is consistent), a plurality of segments with the same-framing requirement are bundled into a combined segment, and all sub-segments in the combined segment have the same downloading frequency. The telemetering packet is divided into isolated segments through constraints such as the whole byte of adjacent continuous cell combinations and the same frame performance among cells, and the isolated segments are the minimum scheduling unit of framing, and are called frame elements for short.

For multiplexing the telemetry packet (i.e. one telemetry packet has multiple cell organization forms, and multiple cell organization forms multiplex the same telemetry packet resource in a time-sharing manner), the frame elements of the telemetry packet should be the maximum union set of the frame elements divided by the multiplexing form used by the telemetry packet.

The frame elements have different downloading frequency requirements in different telemetry modes, and different telemetry modes have different telemetry partition templates. And (3) evaluating the bearing capacity of the partition template: and for a certain telemetry mode M, determining the size of each partition (which can be adjusted according to actual conditions) according to the telemetry division of measurement and control and satellite affairs.

And dividing the image into 4-frame areas, 16-frame areas and 64-frame areas according to the template division. Taking the 4-frame sector as an example, the sector is W30-W70 (41 bytes), and the total carrying capacity is 4 × 41-164 bytes. Generating frame elements according to the telemetry packet source data provided by each subsystem, counting the sum of the frame elements of 4 frames/period, and evaluating the bearing capacity of the current partition. And if the data cannot be loaded, considering the frequency requirement of adjusting the source data or adjusting the size of the partition, and ensuring the adaptation of each partition. And the size requirement conditions of the 1-frame area, the 4-frame area, the 16-frame area and the 64-frame area can be evaluated according to the input information requirement of each family, so as to guide the partition, or the input information is fed back to each family, and the frequency requirement of the input information is adjusted to adapt to the wave channel resource.

Automatic arrangement of channels in the subareas: taking the 4-frame area as an example, the schematic diagram of the area is shown in fig. 8, and the 4-frame cycle is divided into four time division multiplexing areas, i.e., one, two, three, and four. Through early evaluation, the bearing capacity can meet the requirement. The frame elements generated by the telemetry packet are placed in the following templates in sequence.

Constraint conditions are as follows: the border area at each subsection (here one, two, three, four W70 for each subsection) must be the end of the finished frame element, i.e. the frame element is not allowed to be divided, i.e. the frame element is not divided in the time domain, and the blank part is temporarily filled with AA. The same-frequency reuse zone is recommended to be a continuous zone, but the practical situation may be changed, such as: there are 4 frame regions distributed over several discrete sections, an example case is shown in fig. 9 partitioning template. The constraints at this time are still: the end of each sub-segment is the end of a frame cell (in the figure, W70, W211 are both one complete frame cell ends), i.e. a frame cell is not allowed to be segmented in a sub-segment of a frame telemetry.

Automatically generating a ground telemetering analysis frame table: the ground describes the location of information in the telemetry packet in terms of (r, c) (packet number, byte location in the packet), so each frame element has its own corresponding (r, c) coordinate interval. As shown in fig. 10.

The frame elements are distributed into the telemetry partition template through the steps, and the frame elements are described by the (r, c) coordinate intervals of the frame elements, so that a ground telemetry frame analysis frame table can be obtained, and the table is shown below.

And (3) automatically generating a star frame table: according to the one-to-one correspondence relationship between the coordinate of the telemetry packet (r, c) and the housekeeping storage management address (such as RAM address, etc.), a housekeeping frame table can be obtained, which is shown in the following table.

And after the star affair frame table is obtained, converting the star affair frame table into a hex configuration file, and programming a star affair frame table configuration ROM. Meanwhile, the ground telemetering analysis frame table can be reversely extracted from the configuration file of the satellite affair frame table according to the reverse capability, and the seamless conversion of the satellite telemetering frame table and the ground telemetering frame table is completed.

Automatically generating an on-orbit telemetry programming number: the channel table of the programming telemetering area in the satellite frame table can be derived and packaged into a programming telemetering packet format, the satellite is injected, the frame table configuration of the satellite is modified, the on-orbit telemetering frame table modification is completed, and meanwhile, the ground measurement and control long pipe center can also be rapidly adapted to the satellite frame table modification.

Automatically generating a telemetering filing file: and the archived telemetry framing file and the telemetry cell parameter processing method file are exported, so that the workload of file writing is reduced, and the file writing error probability is reduced.

2. A satellite-ground frame table automatic generation method of a sub-packet telemetry system (as shown in figure 4);

template definition: the telemetry frame structure is configured to define the interval (W056-W254) and multiplexing period (e.g., 32 frames/period) of the packet zone.

TABLE 3 sub-packet telemetry frame

Generating a framing basic unit: the minimum framing unit (frame element) of packet telemetry is a telemetry packet which is divided into a plurality of inseparable segments according to the constraints of whole bytes, same framing and the like. The telemetry package is cross-frame, namely the telemetry package is divided into two frames, the division point of the telemetry package must be the boundary point of independent segments (for multiplexing the telemetry package, the independent segments of the telemetry package should be the maximum union of the independent segments divided by the multiplexing modes), and one segment is not allowed to be divided into two frames.

Table 4 remote sensing packet cell organization table

And (3) evaluating the bearing capacity of the partition template: firstly, determining the size of a packet partition, and then completing the automatic generation of a packet frame table according to the packet cycle times in the frame table of each family in the telemetry mode.

According to the template division, the packet partition and the whole cycle period are determined, so that the bearing capacity of the packet partition is 'packet partition size x cycle period'. And calculating the telemetry load bearing requirement of 1 long packet times, 2 long packets times, 3 long packets times … … + n long packets times according to the telemetry packets provided by each subsystem and the cycle times in the period. And comparing the packet zone bearing capacity with the telemetering bearing requirement, if the packet zone bearing capacity is not matched with the telemetering bearing requirement, adjusting the packet zone size or the packet frequency requirement, and filling AA (advanced encryption Standard) or using a filling frame in a part of vacant zones. The size of the required packet partition can be determined according to the remote control packet and the frequency requirement of each family, so as to guide the packet partition to be defined.

Automatic arrangement of channels in the subareas: taking fig. 11 as an example, the packet partitions are W56-W255, which total 200 bytes, and the large cycle period is 64, so the total carrying capacity is 200 × 64 bytes.

And calculating the total telemetering space demand according to the telemetering packet and the frequency demand provided by each subsystem, and ensuring that the bearing capacity meets the demand after adjustment. The telemetering packet with multiplexing frequency requirement should ensure that the interval appearing in the large circulation is uniform and certain isochronism is ensured as far as possible.

The above sub-packet telemetry system is a sub-packet system for a fixed scheduling policy according to a large cycle period. For a dynamic frame table using a priority contention mechanism, the frame table cannot be predefined. And framing the satellite by using a priority scheduling strategy, and analyzing the satellite by a ground analysis mode according to a (head pointer + packet structure).

Automatically generating a ground telemetering analysis frame table: the ground describes the information position in the telemetry packet in the form of packet number and packet length, so that each frame element (i.e. telemetry packet) has its own corresponding packet APID and packet length. As shown in fig. 12.

The frame elements are distributed into the telemetry partition template through the steps, and the frame elements are described by the packet numbers and the packet lengths, so that the ground telemetry frame analysis frame table can be obtained.

TABLE 5 packetized telemetry ground telemetry parsing frame table

And (3) automatically generating a star frame table: according to the one-to-one correspondence relationship between the coordinates of the ground telemetering analysis large table (packet number + packet length) and the housekeeping storage management address, a housekeeping frame table can be obtained.

And after the star affair frame table is obtained, converting the star affair frame table into a hex configuration file, and programming a star affair frame table configuration ROM. Meanwhile, the ground telemetering analysis frame table can be reversely extracted from the configuration file of the satellite affair frame table according to the reverse capability, and the seamless conversion of the satellite telemetering frame table and the ground telemetering frame table is completed.
