Embodiment 1

[0048] The present invention proposes a system design scheme for detecting a test board with a universal load manager, such as figure 1 As shown, the hardware consists of a load manager ground inspection board, which is connected to the ground inspection PC host computer and the load manager of the device to be tested. Used to test common functional interfaces of load managers of different mission models.

[0049] The ground inspection PC is equipped with a bus card, such as 1553B card, CAN bus card, RS422 card or LVDS card; the platform bus and high-speed data interface are directly connected to the ground inspection PC of the analog platform by the traditional scheme, and the upper Machine-to-load management is tested. The other common functional interfaces of the load manager, such as the telemetry and remote control input and output interface, the load scientific data interface, and the load command / engineering response interface, are completed by the detection test board...

Abstract

The invention discloses a universal load manager ground detection test board card, which is deployed between an upper computer and a load manager of a device to be tested, is used for testing common function interfaces of load managers of different task models, and is characterized in that the test board card comprises a load configuration management module and a common function interface module; wherein the load configuration management module is used for storing a load format configuration table sent by an upper computer in an external load configuration table Flash; the reading module is used for reading configuration information pre-stored in an external load configuration table Flash and performing corresponding processing according to a command sent by an upper computer; the communication module is used for sending the generated scientific data, the control signal and the acquisition signal to an external common function interface module, and is also used for sending an execution result of the ground detection test board card to an upper computer; and the common function interface module is used for realizing a connection circuit with a common function interface of the load manager.

Description

technical field [0001] The invention relates to the technical field of aviation and aerospace electronics integration, in particular to a general-purpose load manager detection test board. Background technique [0002] While on-board product research and development, it is also necessary to purchase or design corresponding ground inspection equipment (referred to as ground inspection) to test the functions and performance of on-board products to ensure that on-board products meet mission requirements. [0003] Since the interfaces and protocols of the satellite platform and payload in each mission are different, the satellite will be configured with a payload manager for communication between the satellite and the payload. As a result, the functions and interfaces of the load managers of different types of tasks are also different, so the hardware and software of the ground inspection of the load managers of different types of tasks also need to be designed in a targeted man...
