The invention belongs to the field of instrument control, and particularly relates to a multi-program control instrument control method based on SCPI command. The method comprises the following steps: S1, establishing an SCPI command integration library: establishing the SCPI command integration library of product subsystem commands; s2, packaging the SCPI command integration library: packaging the established SCPI instruction integration library; s3, instrument networking: networking the to-be-networked instrument by using an LAN interface of the to-be-networked instrument and using a switch; s4, identifying the networked instrument: identifying the networked instrument through an IEEE general instruction; and S5, data acquisition: acquiring data of the networked instrument. According to the invention, the interface of the program-controlled instrument is unified, the connection and communication steps of the PC and the program-controlled instrument are greatly simplified, a user does not need to memorize a complex SCPI command, control and data reading of various types of instruments are realized, synchronous data transmission of various measuring instruments can be realized, and the method is suitable for complex measuring conditions.
Description
Technical field [0001] The present invention relates to the field of instrument control technology, and more particularly to the multi-program control method based on SCPI commands. Background technique [0002] Under the boom of intelligent factories and industrial network, the technology that uses program-controlled instruments to remotely detect control over production environments, more and more attention. And with the improvement of production and research and development environment, people's speed and accuracy of the program-controlled instrument and host exchange data and multi-instrument collaborative control are increasingly higher. [0003] The SCPI directive is a set of standard grammar and commands for controlling programmable measurement instruments based on IEEE488.2. It uses a set of tree-hierarchical structures that propose a universal general instrument model. There are two kinds of commands, one for the IEEE general command such as * CLS, * idn (query), * RCL (...
