[0002] A waterproof socket generally consists of a socket body and a waterproof cover. After the waterproof socket is produced, a waterproof quality inspection will be carried out. The waterproof performance test result is determined by spraying water on the waterproof cover and observing the moisture content in the waterproof cover. However, because the waterproof cover of the waterproof socket often has cable passages at the bottom or other locations, these passages may not cause water ingress during the waterproof performance test due to their location. However, due to the water spraying environment, the humidity in the waterproof cover will increase significantly, thereby affecting the normal operation of the circuit. The existing water spraying test does not take into account the impact of the humidity in the waterproof cover on the electrical performance of the socket, resulting in the obtained waterproof performance test results being biased high and the test results being inaccurate.

[0009] Furthermore, the socket current detection module also includes a periodic fluctuation abnormality comparison unit; the periodic fluctuation abnormality comparison unit is used to determine whether the periodic fluctuation abnormality is greater than a preset abnormality threshold.

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation, structure, features and effects of a waterproof socket proposed according to the present invention in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0026] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0027] A specific solution of a waterproof socket provided by the present invention is described in detail below with reference to the accompanying drawings.

[0028] The waterproof socket of the embodiment of the present invention comprises a socket body, and a waterproof cover is installed on the socket body. A socket waterproof performance detection system is also installed in the socket body. The socket waterproof performance detection system is used to correct the waterproof performance test result. In the embodiment of the present invention, the waterproof performance test uses an initial water spraying pressure to perform a water spraying test in the initial stage, and an initial waterproof performance test result can be obtained based on the test process of the initial water spraying pressure, that is, the socket waterproof performance detection system corrects the initial waterproof performance test result.

[0029] It should be noted that the brief process of the waterproof performance test in the embodiment of the present invention is as follows:

[0030] 1. Perform a water spray pre-test before testing to ensure that the direction and pressure of the sprinkler are set correctly, and that the water flow coverage and water pressure meet the test requirements.

[0031] 2. Record all the setting parameters of the sprinkler, including position, angle, height, water pressure and spray pattern, for subsequent analysis and reproduction of test conditions, so that subsequent adjustments to the spray pressure will not affect the test results due to changes in other parameters.

[0032] 3. Perform a safety check before formal testing to ensure that no personnel or other equipment are in the danger zone.

[0033] 4. Start the sprinkler to conduct a water spray test. After obtaining the test results, a test report can be prepared, which should include information such as test conditions, current fluctuation data, pressure adjustment records, and final waterproof level assessment.

[0034] See also Figure 1 , which shows a structural block diagram of a socket waterproof performance detection system provided by an embodiment of the present invention. The socket waterproof performance detection system includes a socket current detection module 101, a water spray pressure adjustment module 102 and a waterproof level correction module 103.

[0035] It should be noted that the socket waterproof performance detection system is only installed when the waterproof socket is tested for waterproof performance, and the installation can be canceled after the test is completed. Therefore, the socket waterproof performance test system can be implemented in hardware through simple and detachable hardware chips such as FPGA. For example, the system may include a current detection device and a processing chip. The current detection device monitors the current data by inserting a plug into the socket. After detecting the current data, it is converted into a current signal and transmitted to the processing chip. The processing chip analyzes and processes the current data and feeds back the processing signal. The processing signal can be used to control the pressure of the water spray device, or control visual hardware such as a display screen to display the waterproof performance results. That is, the processing chip executes the functions of the socket current detection module 101, the water spray pressure adjustment module 102 and the waterproof level correction module 103.

[0036] The socket current detection module 101 is used to obtain current data during the waterproof performance test. It should be noted that the continuous current data in time sequence constitutes a current signal. There is a current signal for each moment, that is, the end moment of the current signal is the corresponding moment.

[0037] If the humidity inside the waterproof cover of the socket changes, the increase in humidity will affect the fluctuation stability of the current signal. For a normal current signal, it should show an obvious sinusoidal change and have a certain periodic stability. Therefore, the socket current detection module 101 obtains the periodic fluctuation anomaly of the current data in real time based on the fluctuation change of the current data under the initial water spray pressure. That is, the greater the periodic fluctuation anomaly, the more the electrical performance of the socket is affected at this time, and the initial water spray pressure adjustment time can be determined based on the periodic fluctuation anomaly.

[0038] Preferably, in one embodiment of the present invention, the socket current detection module further includes a fluctuation analysis unit. The fluctuation analysis unit is used to segment the time period of the real time and its historical time according to a preset cycle step to obtain multiple cycle segments. That is, each cycle segment can be considered as a cycle on the current signal.

[0039] If the current signal is stable, the data between the periodic segments are similar and there will not be a large difference; if the current signal is unstable, not only will there be obvious differences, but the distribution of the differences will also show obvious randomness. Therefore, the fluctuation analysis unit further obtains the difference sequence between two adjacent periodic segments; the difference sequence between the periodic segment at the real-time moment and its adjacent periodic segment is the real-time difference sequence; the initial volatility is obtained according to the variance and average element value of the real-time difference sequence. That is, the average element value represents the degree of difference of the real-time difference sequence, and the variance represents the distribution of the difference; the larger the average element value and the larger the variance, the stronger the current volatility at this time, and the stronger the initial volatility.

[0040] In a specific implementation of the embodiment of the present invention, the product of the variance of the real-time difference sequence and the average element value is used as the initial volatility.

[0041] The fluctuation analysis unit further combines the characteristics of all difference sequences to analyze the fluctuation trend of the entire current signal at this time. If the fluctuation changes more and more, it means that the electrical performance at the real time is more affected. Therefore, the variance of each difference sequence is composed of a variance sequence. For each element in the variance sequence, the element greater than the previous element is recorded as an increasing element. The more increasing elements there are, the stronger the fluctuation change of the current signal tends to become. Therefore, the proportion of increasing elements is obtained; the proportion of increasing elements is multiplied by the initial volatility to obtain the abnormality of periodic fluctuations.

[0042] In one embodiment of the present invention, the preset cycle step is set to 3 seconds, that is, the current signal is intercepted every 3 seconds to obtain multiple cycle segments.

[0043] Preferably, the socket current detection module further includes a periodic fluctuation abnormality comparison unit, which is used to determine whether the periodic fluctuation abnormality is greater than a preset abnormality threshold, and if it is greater than the preset abnormality threshold, the corresponding moment is used as the initial water spray pressure adjustment moment. In one embodiment of the present invention, after the periodic fluctuation abnormality is normalized, the preset abnormality threshold is set to 0.6.

[0044] It should be noted that, in one embodiment of the present invention, the waterproof socket is continuously sprayed with water using the initial water spray pressure, and the abnormality of periodic fluctuations is detected in real time. As the water spraying time continues, the humidity in the waterproof cover will increase, and then the initial water spray pressure adjustment time will be detected. If there is no initial water spray pressure adjustment time after the preset time period, it can be directly considered that the current waterproof performance test result does not need to be corrected, and the current waterproof performance test result is directly output as the final result. The preset time length in the embodiment of the present invention can be set according to the specific model of the waterproof socket, and is not limited here.

[0045] After the initial water spray pressure adjustment moment is detected, the water spray pressure adjustment module 102 is used to reduce the initial water spray pressure according to the periodic fluctuation abnormality at the initial water spray pressure adjustment moment to obtain the updated water spray pressure. That is, the greater the periodic fluctuation abnormality, the greater the impact of the initial water spray pressure on the electrical performance of the socket, and the more it is necessary to significantly reduce the initial water spray pressure to obtain the updated water spray pressure. After obtaining the updated water spray pressure, the waterproof socket continues to be sprayed with water. Because the pressure decreases, the water content will also decrease, and the impact on the electrical performance of the socket will also be weakened. Therefore, it is necessary to evaluate the magnitude of the impact on the electrical performance before and after the update. If the impact on the electrical performance is reduced, the current signal will be close to stability, and there will be no abnormal current data fluctuations, and the frequency information will be weakened. That is, the stronger the frequency difference of the current data before and after the update, the closer the current updated water spray pressure is to the waterproof limit value of the waterproof socket; further combined with the periodic fluctuation abnormality after the update, the greater the periodic fluctuation abnormality, the more it is necessary to further adjust the updated water spray pressure. By iteratively updating the updated water spray pressure until the frequency difference meets the preset conditions, the update can be stopped to obtain the final water spray pressure. That is, the final water spray pressure represents the water spray pressure with the least effect on the electrical performance of the socket.

[0046] Preferably, in one embodiment of the present invention, the water spray pressure adjustment module further includes an adjustment amount calculation unit; the adjustment amount calculation unit is used to normalize the periodic fluctuation abnormality of the initial water spray pressure adjustment moment and then multiply it by the preset maximum pressure adjustment value to obtain the pressure adjustment amount; the pressure adjustment amount is used to adjust the initial water spray pressure to obtain the updated water spray pressure. That is, the updated water spray pressure can be obtained by subtracting the pressure adjustment amount from the initial water spray pressure. It should be noted that the preset maximum pressure adjustment value can be specifically set according to the model of the waterproof socket, which will not be elaborated or limited here.

[0047] Preferably, in one embodiment of the present invention, the water spray pressure adjustment module further includes a current frequency analysis unit; the current frequency analysis unit is used to:

[0048] The current data before and after the update are respectively subjected to signal decomposition to obtain a number of first signal components before the update and a number of second signal components after the update. Signal decomposition can further refine the frequency characteristics, analyze the frequency differences at each frequency level, and make the obtained frequency differences more referenceable. In a specific implementation of an embodiment of the present invention, signal decomposition adopts EMD decomposition, that is, the decomposed signal components are IMF components.

[0049] The first signal component and the second signal component are matched to obtain a component matching pair. The similarity between the first signal component and the second signal component in the component matching pair is obtained. A component matching pair with a large similarity indicates that there is no obvious difference between the two components at the corresponding frequency level. In order to save the amount of calculation, the component matching pair with a similarity less than a preset similarity threshold can be regarded as an abnormal matching pair, and the abnormal matching pair is analyzed in detail. The frequency difference is obtained based on the frequency difference between the first signal component and the second signal component in the abnormal matching pair.

[0050] In a specific implementation of an embodiment of the present invention, the matching algorithm of the first signal component and the second signal component adopts KM matching, taking the first component signal as the left node, taking the second signal component as the right node, and taking the cosine similarity between the components as the edge weight for one-to-one matching. And the similarity calculated subsequently is also the cosine similarity. It should be noted that KM matching and cosine similarity calculation are both technical means well known to those skilled in the art, and will not be elaborated here.

[0051] Preferably, in one embodiment of the present invention, obtaining the frequency difference according to the frequency difference between the first signal component and the second signal component in the abnormal matching pair includes:

[0052] The frequency of the first component signal in each abnormal matching pair is normalized according to the frequency range of the first component signal in all abnormal matching pairs to obtain a frequency weight. The larger the frequency weight, the greater the fluctuation of the current signal before the update, the more obvious the frequency difference information at this frequency level, and the stronger the reference. In a specific implementation of an embodiment of the present invention, the normalization method uses the sum of the frequencies of the first component signals in all abnormal matching pairs as the denominator, and the frequency of the first component signal in each abnormal matching pair as the numerator to obtain the frequency weight.

[0053] For each abnormal matching pair, the frequency difference between the first signal component and the second signal component is obtained. The frequency difference in all abnormal matching pairs is weighted and summed using the frequency weight to obtain the frequency difference. That is, the greater the frequency difference, the greater the impact of the electrical performance in this update, and the closer the update water spray pressure of this update is to the limit water spray pressure of the waterproof socket.

[0054] Preferably, in one embodiment of the present invention, considering that the greater the frequency difference, the greater the change in the impact on the electrical performance in this update, the closer the updated water spray pressure of this update is to the limit water spray pressure of the waterproof socket, the less it is necessary to continue to significantly reduce the updated water spray pressure; and the greater the abnormality of the updated periodic fluctuation, the more it means that the updated water spray pressure of this update still has a certain impact on the electrical performance of the waterproof socket, and the more it is necessary to significantly reduce the updated water spray pressure. Therefore, the water spray pressure adjustment module also includes a water spray pressure iterative update module; the water spray pressure iterative update module is used to map and normalize the negative correlation of the frequency difference to obtain a pressure update coefficient. The periodic fluctuation abnormality of the updated current data is multiplied by the pressure update coefficient, and the product is normalized to obtain an update factor, and the update factor is multiplied by the updated water spray pressure to obtain the updated updated water spray pressure.

[0055] It should be noted that, in one embodiment of the present invention, each time the water spray pressure is updated, a cycle segment after the update is used as the calculation basis for the updated period fluctuation abnormality and frequency difference. The end moment of a cycle segment after the update is calculated according to the above-mentioned calculation method for period fluctuation abnormality; the current signal composed of the end moment of a cycle segment after the update and its historical moment is used as the updated current data signal for signal decomposition. The current signal composed of the start moment of a cycle segment after the update and its historical moment is used as the updated current data signal for signal decomposition.

[0056] In one embodiment of the present invention, the method of negative correlation mapping and normalization is: grouping the opposite groups of frequency differences into powers of an exponential function with a natural constant as the base, and using the output of the exponential function as a pressure update coefficient.

[0057] Preferably, in one embodiment of the present invention, considering that the frequency difference indicates the change in the electrical performance of the socket after the water spray pressure is adjusted, the preset condition is set to the case where the frequency difference is 0. That is, if the frequency difference is 0, it means that there is no change in the electrical performance when the water spray pressure is updated at this time, and it can be considered that the waterproof socket has reached the water spray pressure limit value, and no update operation is required.

[0058] The waterproof level correction module 103 is used to obtain the pressure difference between the final water spray pressure and the initial water spray pressure. The greater the pressure difference, the smaller the water spray pressure actually required for the waterproof socket to ensure that the electrical performance is not affected, and the more the performance test result needs to be corrected. Therefore, it is determined whether the waterproof performance test result needs to be corrected based on the pressure difference, and the waterproof performance test result that needs to be corrected is corrected.

[0059] Preferably, in one embodiment of the present invention, the waterproof level correction module further includes a pressure difference analysis unit; the pressure difference analysis unit is used to take the ratio of the final water spray pressure to the initial water spray pressure as the pressure difference. Because the pressure adjustment is always reduced, the pressure difference is always a value greater than 0 and less than 1.

[0060] Preferably, in one embodiment of the present invention, the waterproof grade correction module determines whether the waterproof performance test result needs to be corrected, and corrects the waterproof performance test result that needs to be corrected, including: if the pressure difference is less than the preset pressure difference threshold, it is determined that no correction is needed; if the pressure difference is not less than the preset pressure difference threshold, it is determined that correction is needed, and the waterproof grade of the obtained waterproof performance test result is adjusted down. In a specific implementation of the embodiment of the present invention, the waterproof grade of the obtained waterproof performance test result is reduced by one grade as the corrected waterproof grade.

[0061] In summary, in order to accurately evaluate the waterproof performance test results of the waterproof socket, the embodiment of the present invention sets a socket waterproof performance detection system in the waterproof socket. The socket waterproof performance detection system mainly takes into account that the change of the water spray pressure will cause the humidity in the waterproof cover to change. If the socket has excellent waterproof performance, it will maintain a stable electrical performance under a strong water spray pressure. Therefore, the system first updates and adjusts the initial water spray pressure by using the abnormality of the periodic fluctuation of the current data, and then uses the frequency characteristics of the current data before and after the update to characterize the stability of the electrical performance until a water spray pressure that does not affect the electrical performance is obtained, that is, the final water spray pressure. The pressure difference between the final water spray pressure and the initial water spray pressure can be used to determine whether the waterproof performance test results need to be corrected and obtain accurate waterproof performance after correction. The embodiment of the present invention corrects the waterproof performance test results of the socket by analyzing the influence of the water spray pressure and the electrical performance of the socket, and obtains an accurate and reference-based test result.
