the instruction receiving and telemetering sending module presets a storage area and divides the storage area;
the command receiving and telemetering sending module reads the external bus command content in real time according to the receiving control time sequence sent by the time sequence control module, wherein the bus command content comprises the following components: instruction code content identification and instruction parameter content;
according to the instruction code content identification in the bus instruction content, the instruction code content identification and the instruction parameter content corresponding to the instruction code content identification are stored in a partition mode; the preferable buses used include a CAN bus, an MIL-STD-1553B bus and the like, the time sequence, the address and the data of bus interfaces are not completely the same, the CAN bus is taken as an example for explanation, and fig. 3 shows a preferable process flow for identifying the instruction to be judged by the CAN bus of the intelligent processing system for the bus control parameter instruction of the space remote sensing camera; the command receiving & telemetry transmitting module preferably instructs the receiving & telemetry transmitting module to transmit 8-bit address data of address signals AD 7-AD 0 when the receiving/reading control timing signal transmitted by the timing control module is at an active-high level (preferably active-high level, low level as a default, preferably the shortest active level duration suggested by the chip manual) according to the reading cycle timing shown in fig. 4, selects the read data address of the SJA1000 chip to be read, and after a period of time, the bus data reading timing signal transmitted by the timing control module (preferably including the receiving/reading control timing signal, the chip identification signal, the chip enable signal, the read data signal, and the write data signal) is active-low to allow the current SJA1000 chip to perform a reading operation, and at the same time, the read data signal is active-low to read the stored data in the corresponding data address of the SJA1000, after the read data signal is read continuously for a period of low level validity (preferably, the shortest valid level duration is suggested according to a chip manual), the system finishes the data reading work of the SJA1000 chip, and the chip enable signal returns to the high level to finish the bus data receiving and reading work. And the SJA1000 chip returns a data valid signal to the time sequence control module to mark that the bus data reading is completed. Wherein the chip enable signal active duration is greater than the read data signal active duration. According to the bus DATA write cycle timing shown in fig. 5, when the receive/read control timing signal sent by the timing control module is at an active level (preferably, the high level is active, and the default condition is low level), an 8-bit address signal to be written is sent, meanwhile, the bus DATA read timing signal sent by the timing control module is sent, when the chip identification signal is high and active, the chip enable signal is low and active, so that the current SJA1000 chip can perform write operation, and simultaneously, the write DATA signal is low and active, and simultaneously, the command receive & telemetry send module sends 8-bit DATA of the bus DATA 7-DATA 0 to be written, and after the chip enable signal and the write DATA signal are both active, the DATA to be returned to the bus by the system is sent to the storage space in the corresponding address of the SJA 1000. After the write data signal and the chip enable signal need to be valid for a period of low level (preferably, according to a chip manual, the recommended duration of the minimum valid level), the chip enable signal returns to high level, and the data write operation of the SJA1000 chip is completed. So far, the system and the bus perform data reading and writing exchange operation.
In the data exchanged with the bus, the address signal and the bus data are transmitted through the same channel, and the received, read, sent and written bus data contain instruction code content identification and instruction parameter content.
And the instruction type judging module reads the instruction code content identification part from the storage area of the instruction receiving and telemetering sending module according to a judging enabling signal sent by the time sequence control module, preferably the high level, and screens the instruction code content identification and the instruction parameter content storage partition which need to be intelligently processed according to the instruction type judging condition which needs to be intelligently processed and is preset by the system.

TABLE 1 decoding/correlation constraint judgment execution condition table in intelligent processing system for bus control parameter instruction of space remote sensing camera
As shown in table 1, preferably, according to the instruction code content identifier and the instruction parameter content that are analyzed by the instruction type determining module and need to be processed intelligently, the instruction code content identifier having the correlation constraint relationship is identified first, and then the instruction parameter content under the current instruction code content identifier is processed intelligently according to the constraint condition between the instruction parameter contents in the instruction code content identifiers having the pre-stored instruction correlation, so as to generate the instruction parameter content meeting the requirements.
The data area to be sent preferably sends the instruction execution state telemetering data to the instruction receiving and telemetering sending module when the sending execution state signal sent by the time sequence control module is highly effective;
all modules in the system of the present invention preferably use the same set of system master clock and reset signals. The master clock generates a reference clock for the time sequence of each module for synchronous work, and the synchronous work of the system can be ensured. The reset signal can enable the time sequence signals used by all the modules at the beginning stage of the system work and set the signals to be in an inactive level.
When the system of the invention has a mutual constraint relation between two or more instructions, preferably only the instruction code content identification in the instruction type judging module needs to be preset and stored correspondingly. The constraint instruction of the system has no upper limit theoretically and can be set at will according to the requirements of the satellite platform system. It should be noted that as the constraint relationship is complicated, the storage space required accordingly increases.
The system of the invention can preferably carry out multilayer time sequence constraint, and the preferable scheme is that after the received instruction code content identifier 1 finishes judging the instruction parameter content of the instruction code content identifier 1 and the pre-stored instruction parameter content of the instruction code content identifier 2 and outputs the instruction parameter content of the instruction code content identifier 1, the instruction parameter content of the instruction code content identifier 1 and the instruction parameter content of the pre-stored instruction code content identifier 3 of the result are judged. The multi-layer mode only needs to update the instruction code content identification needing to be judged by the instruction type judgment condition module, and updates the constraint condition between the instruction parameter content corresponding to the instruction code content identification needing to be intelligently processed and the instruction parameter content of the instruction code content identification with instruction correlation, which is prestored in the decoding & correlation constraint judgment execution condition module.
The system of the invention can preferably carry out unidirectional receiving communication with the bus, only the module of the data area to be sent is needed to be cancelled, the time sequence control module does not output the sending execution state signal, and does not output the sending control time sequence, and the system does not realize the data writing operation to the bus any more, and does not have the data writing bus any more. At the moment, the system can still correctly respond to the bus instruction and carry out intelligent judgment processing.
The system has the advantages that the condition content prestored by the instruction type judgment condition module and the decoding & correlation constraint judgment execution condition module is key data for intelligent judgment processing, and backup design can be carried out on the prestored space of the module;
the pre-stored condition content in the instruction type judgment condition module and the decoding & correlation constraint judgment execution condition module of the system can be pre-stored by the system, can also be set by a bus in real time, and can be updated in real time according to the actual instruction sending condition;
the master clock frequency range of the present system, which is related to the actual system complexity, preferably does not exceed 200 MHz. The more complex the system, the lower the master clock frequency that can be supported. The duty cycle of the master clock frequency is preferably 45% to 55%, the limit being preferably 40% to 60%.
The instruction code content of the system identifies the 1 st and 2 nd bytes of the received bus data, and the corresponding instruction parameter content generally corresponds to the 3 rd byte to the last byte of the received bus data (the maximum byte number of a group of instructions of the bus is uncertain, 8 bytes are used). The instruction code content identification and the number of bytes of bus data occupied by the corresponding instruction parameter content can be adjusted according to the actual system requirement.
The system can automatically judge and process the instruction, thereby avoiding the risk of system execution error caused by violation of instruction constraint during manual transmission. The measurement and control reliability of the system is improved;
the system returns the telemetering data of the instruction execution state after the instruction is executed, and can output the processing result of the intelligent judgment processing system of the remote sensing camera parameter instruction in real time. As an objective basis for verifying whether the system is correct in the working process, the system is a feedback closed-loop system;
the system is applied to the in-orbit remote sensing camera system, so that the operation constraint condition of an in-orbit instruction sending operator is greatly reduced, and the remote sensing camera instruction sending system is greatly simplified.
Those skilled in the art will appreciate that those matters not described in detail in the present specification are well known in the art.
