[0001] This invention relates to a platform and communication control method for space flight verification, belonging to the field of verification and testing technology. Background Technology

[0002] With the continuous development of the electronics industry, the design of domestically produced new electronic components is becoming increasingly mature. To promote the application of these components and other products in spacecraft, thorough verification is necessary. Flight verification, based on ground verification, relies on an on-orbit test platform to conduct space-enhanced environmental suitability tests on components and other products. This serves two purposes: firstly, it verifies the effectiveness of ground tests; secondly, it monitors the actual operational status of components in orbit, providing data support for their subsequent application and promotion. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art, solve the problem that the test unit has a wide variety of flight verifications and cannot be directly carried out on a large test platform, and improve the reliability of flight verification of components and assemblies.

[0004] The objective of this invention is achieved through the following technical solutions:

[0005] A platform for space flight verification includes a management control unit and a power supply and distribution unit;

[0006] The management and control unit mainly has the following functions: to communicate with information management equipment, receive and respond to external commands, and send system information; to manage the power supply and distribution unit and realize data communication with the power supply and distribution unit; to manage the testing unit and realize data communication with the testing unit; and to monitor its own status information.

[0007] The power supply and distribution unit mainly realizes data communication with the management and control unit, sends status information to the management and control unit, supplies power to the test unit, monitors the key status of the test unit, and realizes the power-on and power-off control of the test unit.

[0008] Furthermore, the communication between the management control unit and the information management equipment includes receiving remote control commands, broadcasting platform messages, uploading files, and sending telemetry data;

[0009] Furthermore, the management and control unit includes a management and control module, a power supply module, and a communication and interface module;

[0010] The external primary power supply is converted by the power supply module to supply power to the management control module and the communication and interface module;

[0011] The communication and interface module mainly communicates with the information management equipment via an external bus, receives remote control commands from the information management equipment and sends them to the management and control module; receives on-orbit data from the management and control module and sends it to the information management equipment via the external bus; and receives test data from the test unit.

[0012] The management and control module receives and parses the instructions sent by the communication and interface module, and manages and controls the power supply and distribution unit and the test unit according to the instructions.

[0013] Furthermore, the power supply and distribution unit includes a control and communication module, a power supply and distribution module, and a data acquisition and monitoring module;

[0014] The external primary power supply is converted by the power distribution module to power the control and communication module, the data acquisition and monitoring module and the test unit.

[0015] The control and communication module communicates with the management and control unit via the internal bus, receives and parses control commands, and performs power-on and power-off operations on the test unit; it also packages and sends its own and the test unit's status information to complete data exchange.

[0016] The acquisition and monitoring module is mainly used to acquire the voltage and current signals of the test unit, perform health monitoring based on the threshold information sent by the management and control unit, and send the voltage and current values ​​and health information to the control and communication module.

[0017] Furthermore, a communication control method for a space flight verification platform includes: (1) an information management device sending an OC command (i.e., a programmable control command) to a management control unit, which then powers on and performs initial configuration; (2) a management control unit receiving a power-on command from the information management device, powering on the power supply and distribution unit, and performing initial configuration after power-on; (3) a management control unit receiving a power-on command from the information management device for a test unit, parsing the command, and sending it to the power supply and distribution unit, which then completes the power-on operation of the test unit; (4) a management control unit receiving a power-on command from the information management device for a test unit. (5) The management control unit receives the test start command sent by the information management device and sends it to each test unit, and each test unit starts the test; (6) The management control unit receives the test stop command sent by the information management device and sends it to each test unit, and each test unit stops the test; (7) The management control unit receives the test unit power off command, and after parsing it, the management control unit sends the test unit power off command to the power supply and distribution unit, and the power supply and distribution unit completes the power off operation of the test unit; (8) The management control unit receives the power off command sent by the information management device and disconnects the power supply and distribution unit; (9) The information management device sends an OC command to the management control unit, and the management control unit disconnects the power.

[0018] Furthermore, the management control unit is equipped with a relay J1 at its front end, the power supply and distribution unit is equipped with a relay J2 at its front end, and the test unit is equipped with a relay Kn at its front end;

[0019] The information management device sends an OC command to the management control unit, which closes relay J1 and powers on the management control unit.

[0020] After receiving the power supply and distribution unit power-on command, the management and control unit sends an OC command to the power supply and distribution unit, closing the front-end relay J2 of the power supply and distribution unit to realize the power supply and distribution unit power-on operation;

[0021] After receiving the power-on command from the test unit, the management and control unit sends the command content to the power supply and distribution unit via the internal bus. After receiving the command, the power supply and distribution unit sends the OC command to the test unit, closes the corresponding front-end relay Kn of the test unit, and realizes the power-on operation of the test unit.

[0022] After the management and control unit sends an OC command to the power supply and distribution unit to power it on, it collects the analog voltage and current of the power supply and distribution unit for telemetry. If the telemetry value exceeds the threshold range, it automatically cuts off the power supply and distribution unit.

[0023] After the power supply and distribution unit is powered on, the management and control unit sends configuration information to the power supply and distribution unit. In the next task cycle after receiving the configuration information, the power supply and distribution unit sends configuration status information to the management and control unit. In subsequent task cycles, the power supply and distribution unit sends status data to the management and control unit normally.

[0024] Furthermore, after the management control unit is powered on, it performs initialization and self-test, queries remote control commands, broadcast platform messages and uploaded files, and performs time synchronization based on the broadcast timecode in the broadcast platform message;

[0025] Furthermore, after receiving the remote control command, the management and control unit needs to first verify the command. The verification method is single-byte summation. Starting from the first byte of the command to the last byte, each byte is added together, and the result is the sum. If the command verification fails, it is discarded directly. If the command verification is correct, the command needs to be checked for duplicates.

[0026] If the instruction passes the verification, and it is the same as the previously executed instruction, and the previously executed instruction was within the first two task cycles of this task cycle, then the instruction is a duplicate instruction and will not be executed; otherwise, the instruction will be executed.

[0027] Furthermore, after the management and control unit receives the upload file, it automatically stops collecting telemetry data of the test unit in the current task cycle, and automatically starts collecting telemetry data of the test unit in the next task cycle after the upload file is received.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] (1) This invention can support various types of test units to carry out on-orbit testing, effectively promoting the application of domestically produced components and other products;

[0030] (2) The flight verification platform of the present invention adopts a multi-level power supply mode. When a certain test unit fails, the power supply of the faulty test unit can be quickly cut off without affecting the on-orbit test of other test units, thereby improving the reliability of the flight verification platform.

[0031] (3) The flight test platform of the present invention can automatically receive the uploaded files, support the software reconstruction of the platform and test unit, realize the rapid recovery of faults and the switching of test tasks, and improve the robustness of the system.

[0032] (4) The flight verification platform of the present invention has command verification and deduplication functions, which will not perform misoperation on erroneous or duplicate commands, ensuring stable operation of the system and improving system security. Attached Figure Description
