A test equipment for star service subsystem based on fpga framework

Abstract

The invention discloses satellite task system testing equipment based on a field programmable gate array (FPGA) architecture. The testing equipment comprises a master control module, a TM and TC module, a power supply module, a direct instruction module, a temperature control monitoring module, an OC instruction monitoring module and an analog quantity module. All the hardware modules can be integrated into primary and secondary boxes, the primary box can be independently applied to a stand-alone test, and the secondary box is matched with the primary box for testing and is used for finishing the test of a satellite task subsystem; the operations of the various modules are scheduled in a unified mode by the master control module, only a computer is required during the test, and seamless connection between equipment is realized; compared with a conventional testing system, the testing equipment has the advantages that the number of the equipment is reduced, that the wiring complexity is reduced, and that the testing stability, safety and operability are improved; meanwhile, the testing equipment meets the design requirement on portability.

Description

technical field [0001] The invention relates to a testing device applied to a satellite sub-system of a small satellite, in particular to a testing device for a sub-system of a satellite based on an FPGA framework, and belongs to the technical field of testing. Background technique [0002] The satellite service subsystem is responsible for the scheduling and management of the entire satellite data, which is an indispensable part of the normal operation of the satellite. The quality of the star service sub-system is directly related to whether the whole star can work normally. Testing and evaluating the performance of the satellite subsystem is of great significance to the normal operation of the entire satellite in orbit. At present, in the small satellite satellite service sub-system equipment test, the satellite service test system used is composed of several independent chassis equipment. The system consists of figure 1 As shown, when the system is working, each devic...

Problems solved by technology

In actual application, the system has the following problems: when the system is used, the connection is complicated, the operation is cumbersome, and the various devices cooperate with each other, it is difficult to achieve seamless connection, there are many hidden dangers, and it is easy to break down; there are many devices, and it is difficult to carry and transport. Extremely inconvenient; the entire system has single functions, poor compatibility, and basically no upgrade capability. Every time the star service equipment is changed, the corresponding monitoring equipment needs to be replaced, which is costly and takes a long time; Instruction sending, state simulation and telemetry acquisition are processed by different equipment, which splits the relationship between the incentive and response of the star service subsystem, resulting in the impossibility of automated testing

In summary, the existing satellite equipment testing system is not only complicated to operate and inconvenient to carry, but also has problems such as poor compatibility and difficult upgrades, which is not suitable for further application in the small satellite testing process

With the continuous development of small satellite technology, the design of the star service subsystem is becoming more and more complex, the test work on the star service equipment is becoming more and more in-depth, and the test content is becoming more and more complicated
