Online configuration method for gas station SCADA system process flow diagrams

Abstract

The invention provides an online configuration method for gas station SCADA system process flow diagrams. The method comprises the following steps: S1, drawing process flow diagram templates for various station types, and initializing the templates in a company level data storage server; S2, during station level process flow diagram configurations, according to a corresponding template file acquired by each gas station type, carrying out S3 when the actual process flow of each station is identical to the corresponding template, and carrying out S4 when the actual process flow of each station is different from the corresponding template; S3, saving the acquired corresponding template file in a station level data storage server to complete station level configurations; and S4, carrying out operations on the corresponding process flow diagram template file according to the actual situations of each gas station to complete the station level configurations, saving each updated process flow diagram in the station level data storage server of the corresponding station, uploading each updated process flow diagram in a real time manner to the company level data storage server for storage through the WCF / TCP communication mode, and releasing received data on the Ethernet through the WEB page mode. The method provided by the invention can greatly reduce the workload and cost.

Description

technical field [0001] The invention relates to the technical field of SCADA systems of gas filling stations, in particular to an online configuration method for process flow charts of the SCADA system of gas filling stations. Background technique [0002] SCADA (Supervisory Control And Data Acquisition) system, that is, data acquisition and monitoring control system, involves configuration software and data transmission links (such as digital radio, GPRS, etc.). The SCADA system is a computer-based DCS and electric power automation monitoring system, which can monitor and control on-site operating equipment; Data acquisition and monitoring control and process control and many other fields. Due to the different requirements for SCADA in various application fields, the development of SCADA systems in different application fields is not completely the same. [0003] The SCADA system of gas filling station is a data acquisition and monitoring system for LPG, CNG, LNG and othe...

Problems solved by technology

[0005] According to the existing technology, there are many types of gas filling station sites, and the process flow of each site is different, resulting in a large difference in the process flow chart of the SCADA system of the gas filling station. It is necessary to draw a process flow configuration diagram at each station. At the same time, it is necessary to draw the process flow chart on the WEB side according to the different process flow charts of each station on the WEB server side. The workload is extremely huge, and the deployment and maintenance costs are very high. Figure online configuration method
