Embodiment Construction

[0046] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0047] The invention provides a ground test system for spacecraft equipment, its structure is as follows: figure 1 As shown, including: 1394 bus controller, 1394 bus hub device, 1394 bus storage equivalent device, electric console, at least 1 subrack equivalent device, 1394 bus controller test equipment, 1394 bus analyzer, main control Computers, monitoring stations, servers, power distribution units, fan equipment, cabinets and figure 1 multiple internal temperature sensors not shown.

[0048] The above-mentioned equipment is specifically divided into two types: basic equipment and replaceable equipment.

[0049] Basic equipment refers to the equipment that does not need to be replaced during the entire test process. They form the basis of the entire ground system, including: main control computer, monitoring platform, server, 1394 bus controller test e...

Abstract

The invention discloses a spacecraft equipment ground testing system and a method. An electrical interface, a mechanical interface and a wiring method provided by a cabinet are the same with the actual interface and wiring on a spacecraft; replaceable equipment in the system is arranged in the cabinet; a main control computer power up plug-in box equivalent devices by sending a switch instruction; after power-up, a 1394 bus controller collects the remote sensing data all the plug-in box equivalent devices and sends the data to the main control computer; the main control computer sets a data transmission method of the plug-in box equivalent devices through the 1394 bus controller, sets the transmission contents of the plug-in box equivalent devices through a network bus, and the plug-in box equivalent devices output 1394 data according to the settings; and a monitoring station compares the data output by the plug-in box equivalent devices and a sample packet, and judges if the 1394 transmission is normal. The invention designs the cabinet to stimulate the space limitation, the electrical interface and the mechanical interface on the spacecraft so as to provide a high- simulation test environment for ground joint trial.

Description

technical field [0001] The invention relates to detection technology, in particular to a ground testing system and method for spacecraft equipment. Background technique [0002] Before the spacecraft is designed and put into use, it usually needs to conduct self-inspection and testing of various hardware and software equipment and subsystems installed in it to determine whether the components can work normally and meet the design requirements. [0003] According to the requirements of the spacecraft ground test, the ground test system should first provide a real test simulation environment, provide interface modules that match various aerospace equipment, and simulate the power distribution mode on the spacecraft. Then, in this simulation environment, the hardware and software equipment to be installed on the spacecraft is installed on the interface module, and the simulated power distribution method is used to supply power, and then the working status of the hardware and so...
