Remote sensing satellite load test system and test method, equipment and medium

The invention provides a remote sensing satellite load test system and test method, equipment and a medium. The test system comprises an upper computer, a load test device and a load, wherein the load testing device is used for determining an input interface and an output interface of load data according to an instruction sent by the upper computer and sending a remote control instruction to a load; the load is used for responding to the remote control instruction and sending load data to the load testing device through the input interface; the load testing device is used for processing load data according to an instruction sent by the upper computer, and is further used for performing data format conversion on the processed load data and sending the processed load data to the upper computer through an output interface; and the upper computer is used for testing the converted load data and determining a load test result. Therefore, the real operation state of the load can be better simulated, the functions of
