Embodiment

[0138] When designing the computer program of the star service center, a polling control parameter configuration area is established in the storage area with the address "9000:0000H" in the electrically erasable programmable read-only storage area (EEPROM). The configuration area includes "polling arrangement" Timing Table" and "Polling Priority Table". Create a multi-dimensional array "polling control setting table" and various related variables in the memory area (RAM).

[0139]When the satellite is powered on, the initialization operation is performed, and the parameters in the "9000:0000H" address configuration area are used to assign values ​​​​to the "poll priority" and "poll arrangement timing" in the memory. The "polling priority" variable of each telemetry packet occupies 1 byte. Assuming that the polling period of the satellite is 32 seconds, the "polling arrangement timing" variable occupies 4 bytes. Change the telemetry parameter, "Polling Priority" is 1, which me...

Abstract

The invention discloses an intelligent remote metering polling control method. According to actual use conditions and requirements, a plurality of remote metering polling time sequence changing means such as automatic optimization and manual adding are designed, remote metering resources spared by turn-off operation of one lower computer and off-line operation of one polling package are reasonably distributed to other turned-on lower computers or other online remote metering packages, therefore, the problem of spare remote metering resource waste is solved, the effective utilization rate of the remote metering resources is increased, remote metering management for users and tasks is realized, different working conditions can be satisfied and task requirements can be met. By the adoption of the method, the problem that in a static remote metering polling control method, the effective utilization rate of remote metering resources is low is solved, the intelligent level of satellite remote metering management is improved, data guarantee is provided for satellite in-orbit fault removing, and safety and reliability of satellite in-orbit operation are enhanced.

Description

technical field [0001] The invention relates to an intelligent telemetry polling control method, which is applied to all spacecrafts performing telemetry polling based on the CCSDS subpackage telemetry standard. Background technique [0002] During the operation of small satellites in orbit, a large amount of telemetry data is generated, including the status of satellite equipment, task execution, signal level and temperature conditions, which play an extremely important role in monitoring satellite operating status, realizing autonomous management of satellites, and dealing with on-orbit failures. . The small satellite telemetry system is based on the CCSDS sub-packet telemetry standard, and integrates the characteristics of format telemetry and sub-packet telemetry to form a telemetry format compatible with sub-packet telemetry and format telemetry. The telemetry code rate is 4096bps, 4 frames of telemetry are downloaded per second, the transmission frame length is 128 by...
