[0084] Figure 4 to Figure 19 It is the existing bus structure and data transmission format on the bus.

[0085] Introduction to Bus

[0086] MIL-STD-1553B bus is abbreviated as 1553B bus, which was originally the standard bus of the US military avionics integrated system. Due to the high reliability and safety of the 1553B bus, it is widely used in aviation, aerospace, navigation and other weapon equipment systems, and is known as "a net covering three armies". The research and application of 1553B bus in foreign countries has a history of decades. In 1973, in order to simplify the connection between different aviation equipment interfaces and improve the safety of data transmission, the US military and government announced MIL-STD-1553 Standard, the military adopted this standard for the first time in F16 fighter jets. This standard replaces the huge equipment used to transfer data between various parts of the aircraft and greatly optimizes the performance of the aircraft. In ...

Abstract

The invention provides a fault signal simulation device of an MIL-STD-1553B bus node based on an arbitrary function generator, relates to the field of MIL-STD-1553B bus system fault testing, and aims at solving the problem of poor universality caused by the fact that the whole bus system is comprehensively tested by using the special MIL-STD-1553B customized output data to generate the required fault signals. A fault adding module inputs MIL-STD-1553B protocol suite words, the fault signals are added to the suite words and waveform points are generated from the suite words; the arbitrary function generator outputs MIL-STD-1553B signal waveform to an MIL-STD-1553B level adapter according to the waveform points; and the MIL-STD-1553B level adapter converts the signals into the level standards to transmit messages to the MIL-STD-1553B bus. The fault signal simulation device is used for simulating the fault signals of the bus node.

Description

Technical field [0001] The invention relates to a fault simulation device, in particular to a MIL-STD-1553B bus fault signal simulation based on an arbitrary function generator. It belongs to the field of failure testing of MIL-STD-1553B bus system. Background technique [0002] The MIL-STD-1553B bus system is widely used in the aerospace field. Because in this environment, there are higher requirements for system stability. Therefore, before the MIL-STD-1553B bus system is established, it is necessary to check each node on the bus. , Including the bus controller (BC) and each remote terminal (RT) to conduct a comprehensive test to observe whether it can ensure correct communication under different bus data transmission states. And, if there is a bus failure, whether the bus nodes can implement the correct error handling mechanism. [0003] In the process of testing it, if a dedicated MIL-STD-1553B node device is used, the corresponding manufacturer must have conducted a comprehe...
