Description

Technical Field

[0001] This utility model relates to the field of corrosion monitoring equipment technology, specifically to a corrosion early warning system. Background Technology

[0002] Rusting refers to the chemical or electrochemical reaction that occurs when metal exposed to the atmosphere comes into contact with oxygen, moisture, and other impurities, causing discoloration or corrosion and producing corrosion products that can be observed with the naked eye, such as metal oxides and hydroxides. The corrosion product is rust, commonly known as corrosion or rusting. For some high-value equipment, products, and even weaponry, once rust forms, the resulting economic and safety losses are irreparable. For example, large equipment and military equipment such as precision instruments, precision machine tools, radio equipment, tanks, artillery, ammunition, and aviation spare parts are characterized by high technical content, high value, and most components being metal products. Improper storage during transportation and warehousing will inevitably lead to rusting, affecting performance and accuracy. Therefore, to prevent rusting during transportation and storage, packaging technologies such as vapor phase rust prevention, complete encapsulation, and vacuum packaging are commonly used. Even so, the above packaging can still fail, and such failures are often difficult to detect. There are frequent instances of equipment and gear rusting due to delayed detection of packaging failures. Therefore, it is particularly necessary to monitor the rust-prevention function of the packaging. While some existing equipment includes rust monitoring devices, these are primarily limited to temperature and humidity monitoring, and oxygen content monitoring, resulting in poor and delayed monitoring effectiveness.

[0026] The technical solutions of the present application will be described in detail hereinafter with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0028] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict between them.

[0029] The embodiment describes a corrosion early warning system, which comprises:

[0030] The signal acquisition module is used for acquiring the environmental temperature and humidity, oxygen concentration and corrosion current of the product to be measured.

[0031] The communication module is connected with the signal acquisition module and is in communication connection with the server end at a remote end.

[0032] The server end receives the data fed back by the signal acquisition module and comprehensively judges whether the environment of the product to be measured has a corrosion risk, and issues an alarm.

[0033] The corrosion early warning system of the embodiment combines the corrosion current detection performed by the temperature and humidity, oxygen concentration and new structure corrosion detector, and comprehensively realizes corrosion detection, so that the detection sensitivity can be improved. The diaphragm type corrosion detector of the application can cause corrosion in advance when the internal equipment is damaged and the corrosion possibility condition (certain humidity and oxygen condition) is met, issue an alarm or a corresponding prompt of the corrosion condition, give a warning before the equipment or product protected by the rust-proof packaging is corroded, facilitate the management personnel to perform corresponding processing, improve the rust-proof protection performance and reduce the corrosion risk.

[0034] Specifically, the signal acquisition module comprises a temperature and humidity sensor and an oxygen concentration sensor, which are used for acquiring the environmental temperature and humidity and oxygen concentration of the product to be measured, and sending the acquired data to the server end through the communication module.

[0035] In addition, the signal acquisition module comprises a diaphragm type corrosion detector, wherein,

[0036] As shown in the figure, the diaphragm type corrosion detector comprises: Figure 2

[0037] The substrate 1 is made of a rigid insulating material with good adhesion to iron, such as aluminum oxide;

[0038] ​The metal film layer 2 is formed on at least one side of the substrate 1 and arranged in a regular shape.

[0039] The metal film layer 2 is made of 2N or higher high-purity iron.

[0040] When the corrosion detector is used for corrosion detection, the corrosion detector made of the measuring material is installed in the rust-proof package, and the change of the potential or current on the surface of the measuring material is measured to evaluate whether rust occurs. If rust occurs, it means that the rust-proof package meets the rust condition and needs to be treated. If the corrosion detector can detect corrosion of the internal equipment or product in advance, the corresponding treatment can be performed before the equipment or product is rusted.

[0041] The corrosion detector provided in the embodiment can simulate the corrosion performance of the material of the high-end equipment made of 2N or higher high-purity iron, but can generate a rust change in advance to cause a change in potential and current, thereby feeding back the environmental condition in the rust-proof package and giving a rust-proof reminder.

[0042] The metal film 21 is made by a magnetron sputtering process on the substrate 1. The magnetron sputtering process uses high-energy ions generated by the collision between high-speed electrons and target atoms (2N or higher high-purity iron as the target material) to sputter the target atoms from the surface and deposit them on the substrate 1 to form a thin film.

[0043] In addition, the metal film layer 2 can be arranged on one side of the substrate 1 or on both sides of the substrate 1, which can be adjusted and changed according to design requirements and should be protected by the present application.

[0044] Specifically, the metal film layer 2 includes a plurality of strip-shaped metal films 21, each metal film 21 has a width of 0.1-0.2 mm and a thickness of 1-2 μm. Since liquid droplets and dust are important factors for inducing rust, when the size of the liquid droplets and dust reaches a certain size, for example, 0.1 mm, it becomes a key factor for rust to occur. When the size of the liquid droplets or dust reaches or exceeds the distance between the two metal films 21, it will quickly cause a change in the electrical signal of the metal film layer 2, and the electrical signal will be collected and uploaded in time. In addition, since the metal film 21 is very thin, when rust occurs, the resistance will change significantly, and the electrical signal will also change significantly, which can be collected and uploaded for alarm. It can be said that the small distance and thin line of the metal film 21 are also extremely favorable conditions for early warning of rust occurrence, which can not only detect the presence of liquid droplets or dust, but also detect rust of the protected equipment in advance and give an alarm.

[0045] Optionally, the metal film layer 2 is arranged with the metal thin films 21 evenly spaced, and the metal thin films 21 are arranged in parallel to form a ring-shaped pattern, and the spacing between the metal thin films 21 is 0.05-0.15 mm.

[0046] As shown in Figure 3 the metal film layer 2 includes a plurality of strip-shaped metal thin films 21, and each metal thin film 21 is arranged to form a U-shaped or C-shaped pattern. The metal thin films 21 are closely and regularly arranged, and in the energized state, once contacted with water vapor, the potential difference between adjacent metal thin films 21 can accelerate corrosion, so that the change of the environment can be better fed back. The minimum monitoring impedance sensitivity of the diaphragm type corrosion detector is in the order of uΩ.

[0047] Optionally, when the metal thin films 21 are arranged to form a U-shaped pattern, the middle position of the middle connecting portion of each metal thin film 21 has an n-shaped protrusion protruding in the same direction, and the widths of the n-shaped protrusions on the adjacent two metal thin films 21 are arranged in equal difference. This design can make the metal thin film 21 have multiple protrusions, whether the protrusions at the corners of the U-shaped metal thin film 21 or the protrusions at the corners of the n-shaped protrusion are typical structures of corrosion occurrence, so corrosion of the metal device always starts from the protrusions at the corners first. Therefore, the structure of multiple protrusions and multiple corners can improve the detection sensitivity. In addition, this symmetrical design can effectively utilize the surface space of the substrate, maximize the effective test surface, facilitate the external processing circuit to test the current change of the diaphragm type corrosion detector, make the calculation process more accurate, and improve the detection sensitivity of the diaphragm type corrosion detector.

[0048] When the metal film layer 2 in the diaphragm type corrosion detector is connected to the external detection processing circuit, a conductive hole can be provided on the substrate 1, and the detection processing circuit is connected through a conductive wire. Alternatively, one end of the conductive wire can be welded to the metal film layer 2, and the other end is connected to the detection processing circuit. In addition, a guide electrode 3 can be provided on the substrate 1, the guide electrode 3 is connected to the metal film layer 2, and the thickness or width of the guide electrode 3 can be adjusted as needed to facilitate connection with the conductive wire and further ensure the reliability of conduction, so that the width and thickness of the metal film layer 2 can better meet the design requirements.

[0049] Optionally, the diaphragm type corrosion detector further comprises a guide electrode 3, the guide electrode 3 is formed on the same side as the metal film layer 2, and the two ends of the metal film layer 2 are respectively connected to a guide electrode 3. The guide electrode 3 is used to connect the external detection processing circuit, and the guide electrode 3 is formed on the side of the substrate 1 together with the metal film layer 2.

[0050] The corrosion early warning system of the application can be applied to the logistics transfer process or warehouse packaging of the product to be detected.

[0051] The corrosion early warning system of the application can have the beneficial effects in the logistics process, which are as follows:

[0052] 1. In the logistics process, remote background real-time monitoring can be performed, such as product packaging damage or abnormality, real-time early warning can be performed, and risk hidden danger information can be conveyed to relevant personnel in the early stage of occurrence, so as to reserve time for subsequent remedial measures.

[0053] 2. In the scene where the logistics time is long and there is no 4G signal, such as sea transportation, after the product arrives at the destination (with 4G signal), the data will be packaged and uploaded to the server, and the background will be updated, so as to facilitate understanding of the actual situation of the goods packaging.

[0054] 3. Through data collection and storage, for the packaging failure, the time characteristics and reason collection of packaging failure can be found according to the data law, so as to provide data support for subsequent upgrading and optimization of packaging.

[0055] 4. The packaging product effectiveness data is traceable.

[0057] 1. In the case of product storage, if packaging failure occurs during the product storage process, abnormal information will be sent to the background at a frequency of 30 minutes for early warning, so as to leave time for timely processing of abnormal packaging.

[0058] 2. In the case of multiple products in a common warehouse, the failed packaging can be accurately determined, so as to save time for the warehouse management personnel, and product loss caused by packaging failure can be basically eliminated.

[0059] 3. An alarm indicator light (a small indicator light is used to save power) and an alarm indicator interface (an audible and visual alarm, which consumes more power and needs to increase the battery capacity) are added to the monitoring terminal, if the product packaging fails, not only data abnormal alarm is provided in the background, but also alarm reminder is provided on the monitoring terminal to prompt the relevant personnel to deal with it as soon as possible, and abnormal information is recorded in the storage and cloud data center, so as to facilitate subsequent analysis of the cause.
