Problems solved by technology

[0006] There are deficiencies and limitations in the above methods. First, the timeliness is poor, and changes in the protected state of equipment and equipment cannot be discovered in time. Often, the equipment is in good condition during the last unsealing inspection, but it is found that serious corrosion has taken place during the next unsealing inspection, resulting in Irreparable loss; Second, the traditional detection method has low precision, low efficiency, time-consuming and labor-intensive, and has high requirements on the ability of testing personnel
Third, the traditional detection method relies on people's past experience to judge when to unpack the test. After unsealing, the original packaging materials are difficult to reuse, and new packaging materials need to be replaced to repackage the equipment.
Cannot make the best use of packaging materials, resulting in a lot of waste of resources
[0007] At present, existing metal corrosion monitoring methods and sensor inventions such as CN101865815B, CN100424497C, CN105842148A, etc. are all designed for monitoring the corrosion degree of steel bars in concrete environments such as bridges, and are not suitable for metal corrosion in packaging and sealing microenvironments. monitoring, it is impossible to realize the status diagnosis and early warning of anti-rust packaging
There are no relevant mature products and commercial application cases at home and abroad

Abstract

The invention discloses a corrosion early warning monitor based on a weak accumulated current technology. The monitor comprises a corrosion sensor, a temperature / humidity sensor, a central processingunit, an automatic range switching module, an I / V conversion module, a state display module, a communication module and a power supply module. The control end of the central processing unit is respectively connected with the automatic range switching module and the I / V conversion module, a signal acquired by the corrosion sensor 1 enters the central processing unit sequentially through the automatic range switching module and the I / V conversion module, and a signal acquired by the temperature / humidity sensor is directly output to the central processing unit; measurement data is uploaded to anenterprise cloud platform through the communication module of the central processing unit. According to the invention, the accuracy, the stability and the anti-interference capability of corrosion data measurement are improved, the requirements of weak accumulated current test and evaluation in industrial environment, natural environment, logistics storage and other environments can be met, and the device can also be used as an instrument for rapidly evaluating the effect of a gas phase corrosion inhibitor in a laboratory.

Description

technical field [0001] The invention relates to a corrosion early warning monitoring technology, in particular to a corrosion early warning monitor based on weak cumulative current technology. Background technique [0002] Corrosion refers to the metal exposed in the atmosphere in contact with oxygen, moisture and other impurities, chemical or electrochemical reactions occur, causing discoloration or corrosion, resulting in corrosion products that can be observed with the naked eye. For example: metal oxides, hydroxides, etc., the product of its corrosion is rust, commonly known as rust or rust. [0003] Precision instruments and meters, precision machine tools, radio equipment, tanks, artillery, ammunition, aviation spare parts and other large-scale equipment and ordnance equipment have the characteristics of high technical content and high value, and most of them are metal products. They face the risk of corrosion during transportation and storage. Use performance and pre...
