[0030] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0031] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0032] If similar descriptions of "first / second / third" appear in the application documents, the following description is added. In the following description, the terms "first / second / third" are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It is understandable that "first / second / third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the invention described herein can be implemented in an order other than that illustrated or described herein.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.

[0034] In a corrosive gas environment, such as H2S atmosphere, the metal parts in the electronic circuit are prone to corrosion, causing circuit failure. The sensor can monitor the concentration of corrosive gases, but it cannot monitor the corrosion process. If the circuit fails suddenly due to corrosion, it will cause losses.

[0035] Based on the problems existing in the related art, the present invention can realize progressive warning of the degree of corrosion failure by configuring corrosion warning circuits with different Cantor set structures, provide warning information for circuit failure, and thus achieve the effect of predictive maintenance of the circuit.

[0036] The embodiment of the present invention provides a corrosion warning circuit, including: a PCB body and a grounding resistor, wherein:

[0037] The PCB body is arranged according to N groups of Cantor sets according to the warning requirements, where each group of Cantor sets has a different shape and N is a positive integer;

[0038] One end of a PCB line in a PCB body corresponding to each Cantor set is connected to the grounding resistor and then grounded, and the other end is connected to a detection module to test the corrosion degree of the PCB line.

[0039] It should be noted that:

[0040] The Cantor set is a self-similar set constructed by continuously deleting intervals. The formation process is as follows:

[0041] Initial stage:

[0042] Start from the closed interval [0,1].

[0043] Step 1 (delete the middle one-third interval):

[0044] Divide the interval [0,1] into three subintervals of equal length, namely [0,1 / 3], [1 / 3,2 / 3] and [2 / 3,1].

[0045] Delete the open interval in the middle (1 / 3,2 / 3) and keep the two closed intervals on the left and right [0,1 / 3] and [2 / 3,1].

[0046] Step 2 (delete the middle one-third of the remaining interval again):

[0047] For the two intervals [0,1 / 3] and [2 / 3,1] remaining in the previous step, divide them into three subintervals of equal length respectively.

[0048] Delete the open intervals (1 / 9,2 / 9) and (7 / 9,8 / 9) in the middle of each interval, and keep the four closed intervals [0,1 / 9], [2 / 9,3 / 9], [6 / 9,7 / 9], and [8 / 9,1].

[0049] Step 3 and beyond:

[0050] Repeat this process: for each remaining closed interval, remove the middle third of the open intervals again. This process will continue forever.

[0051] As this process proceeds, the remaining intervals become more and more numerous and smaller.

[0052] The resulting Cantor set is the set of points that remain after all these deletions.

[0053] In this embodiment, the corrosion warning circuit only needs a limited number of Cantor sets, and the first few sets or several of them can be selected according to the prediction granularity requirements.

[0054] In this embodiment, after connecting different groups of Cantor set structures through the detection module, the corrosion degree of PCB lines in different Cantor set PCB bodies is collected. Due to the different shapes of the Cantor set and the different corrosion accuracies of the Cantor set structure, the corrosion conditions of different positions and different severity levels can be obtained, thereby realizing progressive early warning of the degree of corrosion failure.

[0055] The detection module may be completed by connecting a digital signal conversion module or an analog signal conversion module on a circuit board.

[0056] The PCB body material of the Cantor set structure can be set to a copper clad layer structure.

[0057] Combined with the detection results of digital or analog signals in the circuit, a progressive early warning of the degree of corrosion failure can be achieved.

[0058] In some implementations, the circuit structure arrangement formed by the Cantor set can be changed in proportion to adjust the thickness, length and width, and can be flexibly changed according to the circuit arrangement requirements.

[0059] Exemplarily, the detection modules may be connected one by one according to a structure that is gradually subdivided from one end to the other end according to the Cantor set construction.

[0060] In some embodiments, M of the PCB lines are connected in parallel, where M is a positive integer ≥2.

[0061] In some embodiments, the corrosion warning circuit further includes: a digital signal conversion module, wherein M PCB lines are connected in parallel, one end of which is connected to a grounding resistor and then grounded, and the other end is connected to a detection module via a digital signal interface module.

[0062] See also Figure 1 , Figure 1 The structure diagram of a corrosion warning circuit provided is shown in the figure, and the connection example of the digital circuit is shown in the figure. When the corresponding PCB line is corroded, the corresponding digital IO will change from low level to high level.

[0063] In some embodiments, the corrosion warning circuit also includes: a voltage source, a voltage divider resistor and an analog signal conversion module. After the M PCB lines are connected in parallel, one end is connected to the grounding resistor and then grounded, and the other end is connected to one end of the voltage divider resistor. The other end of the voltage divider resistor is respectively connected to the voltage source and the analog signal conversion module, and the analog signal conversion module is connected to the detection module.

[0064] In some embodiments, the detection module includes an ADC module.

[0065] See also Figure 2 , Figure 2 As shown in the structural diagram of another corrosion warning circuit provided, when the corresponding PCB line is corroded, the corresponding analog AIO will change its level, and the corrosion progress can be obtained from the voltage reading by connecting to the ADC.

[0066] For example, the grounding resistor is set to R, and the voltage divider resistor can be selected to be 6R. When the PCB is corroded, the output voltage will change. If the grounding resistor is set to R, the voltage divider resistor can be selected to have different values, so that different output voltages can be achieved after different PCB lines are corroded.

[0067] In this embodiment, a PCB designed with a geometric pattern using a Cantor set is implemented, with copper-clad circuits of different geometric patterns of the Cantor set, and copper-clad circuits of different thicknesses are connected to different digital IOs in the detection module or the main control circuit or connected to analog IOs after a series resistor. In a corrosive gas environment, the copper-clad layer will fail in sequence from thin to thick, the digital circuit output will change to 0 / 1, or the signal detection voltage of the analog IO will change, and reading the detection signal can achieve a progressive early warning of the degree of corrosion failure.
