Description

Technical Field

[0001] The present invention relates to the technical field of remote monitoring and control, and more particularly to a remote monitoring and control system for soil remediation equipment based on OPC communication and remote networking. Background Art

[0002] Industrial waste, agricultural fertilizers, chemical leaks and other factors may lead to the presence of various pollutants in the soil, which not only threatens the soil ecosystem, but also poses a potential risk to human health. In order to restore the health of contaminated soil, soil remediation technology is widely used.

[0003] Soil Vapor Extraction (SVE) is one of the common soil remediation technologies. It installs extraction wells underground and uses negative pressure to extract volatile organic compounds (VOCs) and other gaseous pollutants in the soil, thereby effectively reducing the concentration of pollutants in the soil. Although this method is highly efficient in treating soil pollution, its implementation process also faces many challenges in equipment management and monitoring.

[0004] In traditional soil remediation projects, the management and control of equipment often rely on on-site operations. The adjustment of equipment operating parameters, fault diagnosis and system maintenance usually require the participation of on-site personnel. This method is not only time-consuming and labor-intensive, but also may cause delays in the remediation process when equipment fails, affecting the remediation effect and project progress.

[0005] Therefore, how to provide a remote monitoring and control system for soil remediation equipment, which can not only save time and effort, but also detect and handle equipment failures in a timely manner, thereby avoiding affecting the remediation effect and project progress, is an urgent problem that technical personnel in this field need to solve.
