Problems solved by technology

Therefore, cause existing SCPI command set method to have following shortcoming: SCPI command set is very complicated, and command format comprises uppercase character, lowercase character, full-case character and abbreviation character, and command set comprises command part and parameter part, and command part may save Go to multiple parent node commands (the default command); instrumentation mainly uses embedded development tools, and it is difficult to quickly identify and classify ASCII characters and complex SCPI command formats, etc.

Abstract

The invention provides a method and device for analyzing a SCPI command. The method comprises the steps: reading a created XML file which comprises a plurality of SCPI commands of a preset type and command labels corresponding to the SCPI commands; receiving an SCPI command of a preset type or other types, and matching the received SCPI command with a plurality of SCPI commands of one preset typein the XML file according to a preset algorithm; and acquiring a command mark number corresponding to the successfully matched SCPI command, and calling a corresponding underlying function according to the acquired command mark number. According to the embodiment of the invention, when the SCPI commands of other types are received, a flexible preset algorithm is adopted to be matched with the SCPIcommands in the XML file, so that the XML file can automatically support the SCPI commands of other different types only by describing the SCPI commands of one type.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a method and device for analyzing SCPI commands. Background technique [0002] SCPI (Standard Commands for Programmable Instruments, Standard Commands for Programmable Instruments) defines a set of standard syntax and commands for controlling programmable test and measurement instruments. The SCPI command is an ASCII (American Standard Code for Information Interchange, American Standard Code for Information Interchange) character string, which is transmitted to the instrument through the physical transport layer. A command consists of a series of keywords, and some of them also need to include parameters. The SCPI programmable instrument standard command is an important command set for instrument development. The user of the instrument controls the instrument through the SCPI command to perform related control, query, and data acquisition operations. The instrume...
