Abstract

The invention provides a general portable satellite power supply and distribution system equivalent device. The equivalent device comprises a machine case, a machine case cover, a touch screen, an ARM board, a simulation board card, an adapting board card, an SD card, an aviation plug adapting cable, an interface expanding board, an internal battery, a power plug and a power adaptor. The equivalent device generates a control command through the touch screen to transmit the control command to the ARM board card, the ARM board card generates an equivalent configuration command, the simulation board card simulates interfaces and functions of a satellite power supply and distribution system, and a ground power supply and distribution test device generates an output signal and transmits the output signal to the ARM board. The ARM board judges whether the ground power supply and distribution test device works normally or not, the interface expanding board is connected with the adapting board card, an external power source is connected with the power plug through the power adaptor, and the internal battery and the external power source back up each other. By means of the general portable satellite power supply and distribution system equivalent device, generalization, miniaturization and digitization of the satellite power supply and distribution system equivalent device are achieved, the design concept of the general portable tool provides a train of thought for future ground test device research and development.

Description

technical field [0001] The invention relates to a universal portable satellite power supply and distribution system equivalent device, which can be used as satellite equivalent equipment of the power supply and distribution system in a satellite comprehensive test system. Background technique [0002] The satellite ground power supply and distribution test system is one of the important equipment in the satellite comprehensive test system. The satellite power supply and distribution system equivalent device simulates the satellite and power supply and distribution system by simulating the measurement and control signals of the relevant parts of the satellite disconnected electrical connector. interface to verify whether the function and performance of the ground power supply and distribution test equipment are normal. In order to ensure the safety of the satellite, the satellite equivalent device needs to be used to check the power supply and distribution test equipment to e...

AI Technical Summary

Problems solved by technology

This has certain disadvantages: every time the development of power supply and distribution test equipment needs to newly develop the corresponding satellite equivalent device, it takes a lot of time and financial costs, and affects the process of test equipment development. Equipped with their own satellite equivalents and corresponding packing boxes, it is inconvenient to store, manage and search for use; because the digital meter itself is large in size and can only display a single parameter of a command under test at the same time, in order to meet the test requirements at the same time If the number of instructions and the total number of parameters are large, the volume of the equipment will be larger. Every time the satellite equivalent device is used, it needs to be carried by multiple people, which is time-consuming and labor-intensive.

This technical solution overcomes the shortcoming that the satellite equivalent device of the prior art does not possess generalization, but its disadvantage is: because different types of satellites need special peripheral interface cables, the quantity of cables and electrical connectors is increased; at the same time , the size of the equipment is still large, and it is inconvenient to store and carry; in addition, when using the satellite equivalent device to check the output voltage of the power supply and distribution system, it is entirely up to the operator to manually operate, measure and record according to the self-check table, which is inconvenient to use

This technical solution overcomes the cumbersome shortcomings of satellite equivalent equipment in the prior art, but its disadvantages are: it can only verify the effectiveness of key instructions such as the electrical separation instruction of the separation plug, the tape unlocking instruction, and the emergency shutdown instruction. The function of the equipment is single, and the interface between the satellite and the power supply and distribution system is not fully simulated, and the function and performance of the ground power supply and distribution test equipment cannot be fully verified
