Abstract

The invention belongs to the field of marine corrosion detecting technology and relates to an ocean ship corrosion factor comprehensive detection method based on measurement nodes, a bus and a control supervisory computer. The computer carries out united control and centralized management for the measurement nodes through the bus to achieve comprehensive detection. The control supervisory computer and software carry out control and management for the measurement nodes through the data bus to achieve parameters setting, data upload and download, status inquiry and real-time monitoring of the measurement nodes. Corrosion measurement nodes are used for measuring, converting and storing corrosion potential, corrosion current, corrosion speed and electrochemical noise data. Environmental factor measurement nodes carry out measurement, conversion and storage of temperature, moisture, oxygen content, and salinity parameters and depth parameters of sea water. Mechanical parameters measurement nodes carry out measurement, conversion and storage of stress strain parameters, vibration parameters, impact parameters. The ocean ship corrosion factor comprehensive detection method is simple in detecting steps, convenient to operate and high in automation degree, intelligent degree and online detection efficiency, and has a lot of data collection nodes.

Description

Technical field: [0001] The invention belongs to the technical field of marine environment ship corrosion detection, and relates to a distributed comprehensive detection method for seawater corrosion of ship materials and use environment factors by using a computer-based test system device, in particular to a method for comprehensive detection of marine ship corrosion factors. Detection method. Background technique: [0002] At present, in the marine environment, ships have been in a harsh corrosive environment for a long time. Under the action of seawater and salt spray, various corrosion phenomena often occur on the hull, interior cabins, pipelines and various auxiliary equipment, which not only reduces the The strength of the ship shortens the service life of the ship, and reduces the technical performance of the ship, endangering the safety of the ship, and even causing marine accidents in severe cases. Past experience shows that the corrosion of materials cannot be fun...
