A user-defined serial open bus

Abstract

The invention provides a serial open bus with a self-customized bus structure, which relates to bus design. The open bus of the invention is used for completing communication between a main control module and each functional module. The serial open bus comprises: a reset bus, which is used for sending unified instructions to each module, so that all modules are restored to initial state value at the same time; a power supply bus connected with a power supply for supplying a desired voltage to each module; a network bus, which is used for providing network connection for each module and is alsoused for debugging a module separately; and a user-defined bus, used to add the corresponding functional bus according to the requirements. With embedded technology and computer technology as the core, a DSP, an ARM, a single-chip microcomputer, an FPGA and other high-performance devices are used to construct the user-defined bus, which exhibits high autonomy. Each module can customize the bus structure according to the specific military test requirements, resources are saved, the environmental test can be past, and the localization rate of the equipment is improved.

Description

technical field [0001] The invention relates to bus design, in particular to a self-defined serial open bus. Background technique [0002] Since the United States developed testing equipment for military electronic equipment in the 1950s, the types have continued to increase, and related research work has received more and more attention. With the improvement of the tactical performance and internal structure complexity of weapons and equipment, the requirements for supporting test equipment in the process of research and development, production and use of weapons and equipment are getting higher and higher. Since the mid-1970s, my country has carried out research on automatic test equipment for missiles. After decades of exploration and practice, it has successively developed and equipped multiple sets of missile comprehensive test equipment for the army. At present, missile testing equipment is mostly realized by VXI, PXI or LXI bus, among which VXI bus is mostly used. H...

Problems solved by technology

However, the application of the LXI bus is mostly concentrated in the distributed test occasions. For highly integrated portable devices, although it has a good development prospect, it has not been well applied.

[0005] Although the above-mentioned VXI, PXI, and LXI buses have powerful test functions and are supported by instrument standards, they are all in the form of commercial buses after all. Their resource configuration and management cores are relatively closed and will not be completely open to users. It is not conducive to the fault location and analysis of military equipment at the grassroots level

On the other hand, due to the relatively low test depth of missiles at the grass-roots level of the army, and fewer restrictions on the test process, the demand for standard instruments is relatively low; and the remaining resources of standard instruments may affect the portability and reliability of equipment.
