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, comprising: abstracting the switch matrix network as a directed graph, and abstracting the microwave nodes in the switch matrix network as an internal cascade node of the directed graph; The configuration script file saves the directed graph connection relationship of all microwave device nodes in the switch matrix network; if the internal routing structure of the switch matrix network changes, only the routing configuration of the changed microwave nodes in the corresponding script file needs to be changed; Directed graph connection relationship, through the depth-first search algorithm, search all paths between the input end and the output end of the switch matrix network; according to all the paths searched, establish the routing table of the switch matrix network; according to the actual control route, open the route corresponding path in the table. By introducing the script control technology, the problems of repeated development and time-consuming and laborious in the software development of the switch matrix network are solved.

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...
