Method for monitoring and managing industrial on-site bottom layer device through expression analysis

Abstract

The invention provides a method for monitoring and managing an industrial on-site bottom layer device through expression analysis. The method comprises the steps that firstly, expression configuration is conducted by a user, wherein an operand belonging to the name of a monitoring unit in operands contained in an expression is surrounded by two single quotes, an operational character contained in the expression must belong to operational characters defined in advance, and an immediate operand contained in the expression must be within a value range defined in advance; secondly, the legality of the expression is verified; thirdly, expression analysis and calculation are conducted, a calculation result is stored for monitoring and managing the industrial on-site bottom layer device. According to the method, identification of the operand in the expression analysis process is achieved, the legality of the expression can be better verified, the types of stack elements can be rapidly identified in the process of expression calculation, rapid calculation is facilitated, the operation performance of a data statistical system is improved, and control feedback of the on-site bottom layer device is rapidly achieved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for realizing the monitoring and management of bottom-layer equipment in industrial sites by using expression analysis. Background technique [0002] In the monitoring and management of the underlying equipment on the industrial site, the statistical system is the core sub-module of the data statistical analysis subsystem in the real-time database system. Usually, the statistical system collects the required data from the underlying equipment, then analyzes and calculates the expressions configured by the user (usually the on-site underlying equipment manager), and stores the calculation results for further statistical analysis. The results of statistical analysis can be used to assist field equipment managers to implement or directly perform corresponding control operations on the underlying equipment. From this process, it can be seen that the "parsing" of the expre...
