Design of Intelligent Anticorrosion Monitoring Device for Grounding Grid of Military Equipment Manufacturing

为解决军工制造生产现场接地网易遭受土壤环境的电化学腐蚀,同时还遭受泄流电流引起的电腐蚀,严重危害军用装备制造和人身安全的问题,提出一种基于PLC的军用制造行业接地网电化学保护和腐蚀监控智能控制设计方案。采用外加电流阴极保护,硬件部分结合西门子S7-300平台,软件部分运用Step7软件,实现对生产现场接地网的免开挖防腐和控制。结果表明:该方案能满足对离散制造行业生产现场接地网的远程控制与监控,确保军用生产设备的安全、经济、稳定运行。

In view of the military manufacturing production site, the grounding grid not only by the electrochemical corrosion of soil environment, but also caused by discharge current electric corrosion, which caused serious damage to the equipment and personal safety. In order to overcome the above problems, this paper presented an intelligent control design scheme for electrochemical protection and corrosion monitoring of grounding grid in military manufacturing industry based on PLC, the design adopted the impressed current cathodic protection, hardware used the Siemens S7-300 experiment platform and software used Step7, which realized the free of the excavation of grounding systems located in soil corrosion protection and control, at the same time, the system integrated data processing, collection, analysis and feedback command. The results show that the design satisfied the remote control and monitoring of the grounding grid in the discrete manufacturing industry and ensured the safety, economic and stable operation of the military production equipment.
