A system and method for automatic identification of sealing points based on p&id

Abstract

The invention discloses a P&ID (Piping and Instrumentation Diagram)-based seal point automatic identification method. The method comprises the following steps of performing basic application of a P&ID: analyzing and storing the P&ID, and loading the P&ID; performing business application of the P&ID: identifying and annotating the analyzed and stored data information in the basic application of the P&ID, and generating a seal point ledger according to the data information generated in the identification and annotation process, thereby mutual locating of the seal point ledger and the loaded P&ID; and exporting the P&ID: exporting the annotated P&ID in the business application step. The method has the beneficial effects that the problems of low efficiency of manual annotation and seal point information input, non-uniform levels of construction personnel, and non-unified ledger standards of manual identification and input at present are solved; and the data accuracy is improved in an existing LDAR management system, and unified standards of seal point basic data are ensured.

Description

technical field [0001] The invention relates to the technical field of petrochemical sealing point leakage detection and repair, in particular to a P&ID-based automatic sealing point identification system and method. Background technique [0002] In 2015, the Ministry of Environmental Protection promulgated the "Guidelines for the Investigation of VOCs Pollution Sources in the Petrochemical Industry" and "Guidelines for Leakage Detection and Repair of Petrochemical Enterprises". These two programmatic documents guide the leakage management of petrochemical enterprises. [0003] The basis of existing seal point leakage detection and repair is perfect seal point filing. The existing sealing point filing methods are as follows: ①Manually identify the sealing points in the paper drawings of P&ID (Piping and Instrumentation Diagram, that is, the flow chart of process pipeline instrumentation); ②Verify the location on site, record the sealing point information, and detect; Points...
