Abstract

The invention discloses a method for automatically generating a pipeline meter flow diagram. The method comprises the following steps that original data of the pipeline meter flow diagram are acquired and converted into standard data ordered according to names and attribute values; corresponding graph blocks are retrieved from a graphic base according to the names of pipeline meters in the standard data, and attribute values of the retrieved graph blocks are modified according to corresponding attribute values in the standard data, wherein the graphic base is established in advance according to the categories of the pipeline meters. The categories of the pipeline meters comprise meter bodies, pipelines and devices. The graph blocks in the graphic base are categorized according to the meter bodies, the pipelines and the devices. Each graph block comprises the name and the attribution value of a corresponding pipeline meter. The pipeline meter flow diagram is generated according to all the retrieved graph blocks.

Description

technical field [0001] The invention relates to the field of chemical instruments, in particular to a method for automatically generating a pipeline instrument flow chart. Background technique [0002] Innovating working methods and improving technical means are shortcuts to improve work efficiency and work quality with low input and high output. P&ID (ProcessandInstrumentDiagram, flow chart of pipeline instrumentation) utilizes uniformly stipulated graphic symbols and text codes to map all the equipment, instruments, pipelines, valves and main pipe fittings required for the establishment of chemical process equipment according to their respective functions and processes. The requirements are combined to play the role of describing the structure and function of the process equipment. The design of P&ID is completed on the basis of PFD (ProcessFlowDiagram, process material balance diagram). P&ID is the basis for professional design of process, instrumentation, piping and eq...
