Abstract

The invention provides an acquisition method and apparatus for a reflected voltage in a specified location of a 1553B network. According to the acquisition method provided by the invention, an incident voltage and a reflected voltage of a load terminal are analyzed and processed by using a time-domain analyzing method (such as a travelling wave method) or a frequency domain analyzing method (such as an S domain solving method), and simulation processing is performed; and finally according to a processing result of the simulation, waveform quality is vitrified. According to the voltage acquisition method provided by the invention, a loss effect of a transmission line in a time domain can be simulated better, and a to-be-verified target bus topological structure can be simulated accurately.

Description

technical field [0001] The invention relates to the field of bus verification, in particular to a method and a device for acquiring reflected voltage at a designated position in a 1553B network. Background technique [0002] The 1553b bus is an information transmission bus standard formulated by the US military for aircraft equipment. It is widely used in the military field due to its good real-time performance, reasonable error control measures, unique mode commands, and high bus efficiency. ; At present, the 1553B bus is often used in the control system of missile weapons to provide a message path between the bus controller in the above-mentioned control system and all relevant remote terminals. [0003] Among them, the above-mentioned missile weapon control system has the characteristics of high real-time performance, one-time use and short working time, high reliability requirements, and the need for inter-stage separation operation during flight, and the use of the 1553...
