Environmental corrosion can not only affect the appearance of the monitoring equipment, but also affect the performance of the monitoring equipment, thereby reducing the accuracy of environmental monitoring.

[0003] Therefore, while monitoring the environment, it is also necessary to monitor the corrosion rate of the environment around the monitoring equipment. The current method for detecting environmental corrosion rate is to hang polished pure silver or pure copper sheets on site. After a period of time, the corrosion thickness of the corroded pure silver or pure copper sheets is manually observed to obtain the thickness of the corrosion layer, and then the thickness of the corrosion layer is used to calculate the environmental corrosion rate detection result.

[0004] However, this manual observation method is affected by various external factors (such as the state of the observer and the condition of the observation equipment), which has a certain impact on accuracy. How to improve it has become a technical problem that needs to be solved at present.

[0005] With respect to the above-mentioned related technologies, the inventors believe that there is a defect that the accuracy of the environmental corrosion rate detection results is low. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-2 This application is described in further detail.

[0023] The present application embodiment discloses a corrosion rate monitoring remote transmission system based on the resistance method. Figure 1The corrosion rate monitoring remote transmission system based on the resistance method includes a constant current source module 10, a test sheet 20, a reference sheet 30, a first voltage detection module 40, a second voltage detection module 50, a timing module 60, a control module 70, a wireless transmission module 80 and a processing terminal 90. The control module 70 is respectively connected to the timing module 60 and the constant current source module 10, the test sheet 20 is respectively connected to the constant current source module 10 and the reference sheet 30, the constant current source module 10, the test sheet 20 is connected to the constant current source module 10 and the reference sheet 30, the first voltage detection module 40 is connected to the test sheet 20, the second voltage detection module 50 is connected to the reference sheet 30, the first voltage detection module 40 and the second voltage detection module 50 are both connected to the control module 70, the control module 70 is also connected to the wireless transmission module 80, the control module 70 and the processing terminal 90 are connected through the wireless transmission module 80, the surface of the reference sheet 30 is coated with an anti-corrosion coating to prevent the reference sheet 30 from being corroded, and the test sheet 20 is exposed to the environment.

[0024] During operation, the timing module 60 outputs a timing signal to the control module 70. The control module 70 receives the timing signal and outputs a control signal to the constant current source module 10 when the timing signal reaches a preset value. The constant current source module 10 receives the control signal and outputs a stable and constant current. The current passes through the test sheet 20 and the reference sheet 30 in turn. Since the constant current source module 10, the test sheet 20 and the reference sheet 30 are in series, the currents applied to the test sheet 20 and the reference sheet 30 are equal.

[0025] When current passes through the test sheet 20 and the reference sheet 30, the first voltage detection module 40 detects the voltage on the test sheet 20 and outputs a first voltage detection signal, the second voltage detection module 50 detects the voltage on the reference sheet 30 and outputs a second voltage detection signal, the control module 70 receives the first voltage detection signal and the second detection signal, and transmits the timing signal, the control signal, the first voltage detection signal and the second detection signal to the processing terminal 90 via the wireless transmission module 80.

[0026] Since the test sheet 20 has not undergone any anti-corrosion treatment, the test sheet 20 will be corroded by the environment, while the reference sheet 30 will not be corroded because it has undergone anti-corrosion treatment. In addition, since the reference sheet 30 and the test sheet 20 are made of exactly the same material and size, their resistance should theoretically be the same. However, when the test sheet 20 is placed in the environment and corroded, the cross-sectional area becomes smaller. At this time, after applying the same current to the reference sheet 30 and the test sheet 20, the voltages on the reference sheet 30 and the test sheet 20 are different. Similarly, when the same current is applied, the resistance of the reference sheet 30 and the test sheet 20 can be calculated by measuring the voltages on the reference sheet 30 and the test sheet 20 respectively. The cross-sectional size of the reference sheet 30 and the test sheet 20 can then be deduced from the resistance, and the corrosion rate of the environment can be obtained by combining time. The method of calculating the corrosion rate in this way improves the accuracy of the environmental corrosion rate detection results compared to manual observation.

[0027] Therefore, when the processing terminal 90 receives the timing signal, the control signal, the first voltage detection signal and the second detection signal, the environmental corrosion rate can be calculated according to a preset program. The program is a calculation method well known to those skilled in the art and will not be described in detail here.

[0028] In this embodiment, in order to make the reference sheet 30 and the test sheet 20 have good conductive effects, copper foil is used for the reference sheet 30 and the test sheet 20. In order to improve the stability and reliability of signal transmission, the wireless transmission module 80 is a Lora wireless communication module. In other implementation methods, the reference sheet 30, the test sheet 20 and the wireless transmission module 80 can be selected according to actual conditions and are not limited here.

[0029] Reference Figure 2 Furthermore, in order to improve the convenience of system use, the control module 70 is also connected to the power module 300. The power module 300 uses a removable and rechargeable battery. The power module 300 provides the electrical energy required for the constant current source module 10, the first voltage detection module 40, the second voltage detection module 50, the timing module 60, the control module 70 and the wireless transmission module 80 to work.

[0030] In this embodiment, the processing terminal 90 includes a main control chip 902, a wireless receiving module 901 and a display module 903. The main control chip 902 is connected to the wireless receiving module 901 and the display module 903 respectively. The wireless receiving module 901 and the wireless transmission module 80 are communicated and connected to realize the connection between the control module 70 and the main control chip 902. The main control chip 902 is used to receive the signal transmitted by the control module 70 to calculate the corrosion rate and output the display signal. The display module 903 receives the display signal and displays the corrosion rate for the convenience of the staff to view.

[0031] In order to further facilitate the installation and connection of the test sheet 20 and the reference sheet 30, the test sheet 20 and the reference sheet 30 are arranged on the PCB board 100. In addition, a protective box 200 is also arranged on the PCB board 100, and the reference sheet 30 is arranged in the protective box 200, which further prevents the reference sheet 30 from being corroded, thereby indirectly improving the accuracy of the detection result.

[0032] The implementation principle of a corrosion rate monitoring remote transmission system based on the resistance method in an embodiment of the present application is as follows: by setting a test sheet 20 and a reference sheet 30, the test sheet 20 is exposed to the air, and the reference sheet 30 is subjected to anti-corrosion treatment. When the test is performed, the timing module 60 counts, and the preset time control module 70 controls the constant current source module 10 to output a constant current to the test sheet 20 and the reference sheet 30. The voltages on the test sheet 20 and the reference sheet 30 are tested respectively by the first voltage detection module 40 and the second voltage detection module 50, and the voltages are transmitted to the processing terminal 90 through the wireless transmission module 80. The processing terminal 90 calculates the resistance of the test sheet 20 and the reference sheet 30 according to the applied current and voltage, and obtains the current cross-sectional area of ​​the test sheet 20 according to the resistance, and then compares it with the reference sheet 30 to obtain the reduction in the cross-sectional area, and then calculates the corrosion rate of the environment.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
