Embodiment Construction

[0048] It should be pointed out that the following detailed description is exemplary and intended to provide further explanation to the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0049] A switch matrix network has multiple inputs and multiple outputs. One input terminal can have multiple output terminals, and one output terminal can have multiple input terminals. Each input and output are connected by microwave switches and microwave devices, resulting in numerous and complicated routes. In theory, a matrix with n inputs and m outputs can have n*m ​​routes. For a matrix with 100 input terminals and 100 output terminals, there will be 10,000 routes in theory, and the traditional control software development technology basically cannot be developed, but the present invention is not limited by the number of input...

Abstract

The invention discloses an autonomous path finding switch matrix network control method and system based on a script configuration type. The method comprises the following steps: abstracting a switchmatrix network into a digraph, and abstracting microwave nodes in the switch matrix network into internal cascading nodes of the digraph; configuring a script file, and storing a digraph connection relationship of all microwave device nodes in the switch matrix network; if an internal routing structure of the switch matrix network changes, only changing the routing configuration of the changing microwave nodes in the corresponding script file; searching all paths between an input end and an output end in the switch matrix network via a depth-first search algorithm according to the digraph connection relationship of the nodes; establishing a routing table of the switch matrix network according to all searched paths; and opening corresponding paths in the routing table according to the actually controlled routing. The script control technology is introduced to solve the problems of repeated development, time wasting and labor wasting in the software development of the switch matrix network.

Description

technical field [0001] The invention belongs to the technical field of automatic testing, in particular to an autonomous pathfinding switch matrix network control method and system based on script configuration. Background technique [0002] As the scale and integration of automatic test systems increase, an automatic test system often includes a variety of test instruments, which requires a switch matrix network for input and output interconnection. After the traditional switch matrix network design is finalized, the matrix access and control software are also fixed, which brings three problems: 1) To modify the switch matrix hardware, the control software needs to be modified. 2) The matrix path is complex, the number of cascading layers is large, and the software development is difficult. 3) Traditional switch matrix network software is not reusable. To develop a switch matrix, a set of control software needs to be maintained. [0003] The switch matrix network is widel...
