A generalized design method for satellite ground power supply and distribution test equipment

Abstract

A satellite ground power supply and distribution test equipment generalization design method relates to the satellite ground power supply and distribution test equipment design field. A largest envelope which makes that equipment resource configuration reaches demands of all the researched-satellite-to-ground power supply and distribution test equipment is included. Enough redundant backups and extensible resources are reserved and a construction rule of various kinds of resources in the equipment is made. Aiming at different requirements of different satellites to a cell on-off interface circuit and the like, a driving power supply in the power supply and distribution test equipment and a passive contact point of an electromagnetic relay are simultaneously led out to an equipment output interface, and each satellite can complete control mode conversion through a special design of a cable plug according to a detailed design of a satellite power supply controller. The test equipment can be applied to a subsequent satellite without any reconstruction. Material resource cost is greatly reduced and rapid interchange of the test equipment among the different satellites is realized. Simultaneously, a processing unit can realize production line type development and a development period of the equipment is greatly shortened.

Description

technical field [0001] The invention relates to the design field of satellite ground power supply and distribution test equipment, in particular to a generalized design method for satellite ground power supply and distribution test equipment. Background technique [0002] Power supply and distribution test equipment is the key equipment for satellites to provide wired commands and collect wired parameters. At present, due to the different power, wired command control, wired parameter collection quantity, content and satellite-ground interface of each model, it is necessary to develop a special for each satellite. This method not only causes a great waste of resources, but also when a certain type of power supply and distribution test equipment fails and cannot be repaired quickly, the equipment of other satellites cannot be used due to the incompatibility of equipment between models. Testing on this model may affect the progress of satellite testing. [0003] The functions ...

[0002] The power supply and distribution test equipment is the key equipment for providing wired commands and collecting wired parameters for satellites. At present, due to the different power, wired command control, wired parameter collection quantity, content and satellite-ground interface of each model, it is necessary to develop a special for each satellite. This method not only causes a great waste of resources, but also when a certain type of power supply and distribution test equipment fails and cannot be repaired quickly, because the equipment between models is not common, the equipment of other satellites cannot be used. Tested on this model, it may affect the satellite test progress

[0003] The functions of the current power supply and distribution test equipment are relatively unified. For example, a satellite ground power supply and distribution test system based on PLC and Profibus field bus disclosed in the utility model patent application number CN200720173870.4, although it can meet the test requirements of satellites, but Not universal, there are many deficiencies: due to the relatively fixed internal hardware design of the dedicated power supply and distribution test equipment, all the peripheral resources corresponding to the digital module are not fully equipped and led to the external interface of the equipment, the equipment of a certain satellite Interfaces, indicators, and resources cannot be applied to other models, and each satellite needs to be equipped with dedicated power supply and distribution test equipment, which wastes a lot of material costs; it is necessary to organize satellite power supply and distribution test post designers to provide power supply and distribution for each satellite It consumes a lot of manpower cost to prepare documents such as production technical requirements and interface design for testing equipment; the contracting unit needs to make separate structures, circuits, and contacts for each satellite’s power supply and distribution testing equipment, and draw relevant drawings, greatly It reduces the development and production efficiency of equipment, and cannot adapt to the current rapidly increasing number of models and the needs of parallel testing and rapid testing of multiple satellites
