Description
Technical Field
The application relates to the technical field of rocket test, in particular to a test method and device of a rocket bus switcher, a computer readable storage medium, a processor and a rocket test system.
Background
The active main stream carrier rocket avionics system mostly adopts a communication scheme based on a 1553B main line, the 1553B main line mainly comprises a main line (BUS) and a sub-line (STUB), and in order to improve the reliability of communication, matching resistors are required to be connected to two ends of the main line respectively for impedance matching so as to improve transmission waveforms and improve the anti-interference capability.
The carrier rockets are all in a multi-stage relay working design mode and are mostly in a series configuration, namely after one-stage combustion is exhausted, the carrier rockets throw off the residual shells of one-stage through a separation design and ignite a second-stage engine to continue flying, so that the carrying capacity is improved. The disconnection of the multi-stage carrier rocket can cause the disconnection of the main line of 1553B, and for this reason, a switch is often designed at the upper stage of the disconnection surface, and a matching resistor is added at the tail end of the main line through the control of a relay.
The functions of the switcher are generally tested when 1553B cables leave a factory, however, once the switcher is installed on a launch vehicle, the test coverage is not enough, and certain hidden dangers exist.
The test of the carrier rocket is generally divided into factory test and shooting range test of a general assembly plant, the test states of the general assembly plant and the shooting range test are generally approximate, and the test states are divided into test in a half rocket loading state and test in a full rocket loading state.
The launch vehicle adopting the 1553B architecture generally leads 1553B to ground measurement, launch and control, and RT and MT nodes are arranged on the ground measurement, launch and control for control and monitoring. In order to obtain monitoring data during the test process, the switch is not generally controlled to switch the matching resistor during the total inspection test under the condition of full arrow loading. The switching test of the matching resistor is usually performed under the condition of half-loading arrow, generally performed in a technical area, and by designing a special general inspection, the actual separation of the connector from the connector is performed in the general inspection test process, and the control of the switcher is performed.
However, this test method has a fatal defect that the test coverage is seriously insufficient because: 1553B is very reliable in design and large in waveform identification margin, even if a single end does not have a terminal resistor, normal communication can still be performed under most conditions, but waveform distortion can be found to be serious through an oscilloscope. This may result in that even if the switch or the switch control circuit is abnormal, the normal test flow is completely undetectable, and the test flow design has the hidden trouble of insufficient coverage.
