[0017] Embodiment 1
[0018] As Figure 1 shown, this application provides an explosion-proof detection method for the electric control cabinet of an intelligent warehouse. The method includes:
[0019] P10: When the intelligent warehouse generates warehousing item change information, trace the historical warehousing environment of the warehousing item type, and generate the warehouse characteristic temperature and the warehouse characteristic air pressure;
[0020] Specifically, when there is a change in the warehousing items in the target intelligent warehouse, trace the historical warehousing environment information according to the type of the warehousing items, that is, through data mining, screen out the common environment information of each type of warehousing item from the historical warehousing environment information, including the common warehousing temperature and the common warehousing air pressure, and use this as the warehouse characteristic temperature and the warehouse characteristic air pressure, which can be used as a reference for the parameter setting of the electric control cabinet.
[0021] P20: Configure the constant air pressure of the electric control cabinet according to the warehouse characteristic air pressure;
[0022] It should be understood that, with reference to the warehouse characteristic air pressure, configure the constant air pressure of the electric control cabinet of the target intelligent warehouse. Generally, the constant air pressure of the electric control cabinet should be greater than the warehouse characteristic air pressure to ensure the safety of the electrical equipment in the electric control cabinet.
[0023] P30: Interact with the electric control cabinet, receive the electrical working parameters of the electric control cabinet, perform control mode segmentation on the electrical working parameters of the electric control cabinet, and generate multiple groups of continuous electrical working parameters of the electric control cabinet;
[0024] Furthermore, as Figure 2 shown, step P30 of the embodiment of this application further includes:
[0025] P31: The electrical working parameters of the electric control cabinet include the first-timing electrical working parameters of the electric control cabinet and the second-timing electrical working parameters of the electric control cabinet, where the first timing and the second timing are adjacent timings;
[0026] P32: Evaluate the deviation distance of the electrical operating parameters of the first sequential electrical control cabinet and the electrical operating parameters of the second sequential electrical control cabinet to generate a modal distance coefficient;
[0027] Further, step P32 of the embodiment of the present application further includes:
[0028] P32-1: Traverse the attributes of the electrical operating parameters and configure the attribute deviation threshold;
[0029] P32-2: Calculate the deviation of the electrical operating parameters of the first sequential electrical control cabinet and the electrical operating parameters of the second sequential electrical control cabinet to generate a modulus of the deviation of the electrical operating parameters;
[0030] P32-3: Extract the mean value of the modulus of the deviation of the electrical operating parameters that is greater than or equal to the attribute deviation threshold and set it as the modal distance coefficient.
[0031] P33: Based on the modal distance threshold and in combination with the modal distance coefficient, perform adjacent time-sequence clustering on the electrical operating parameters of the electrical control cabinet to generate multiple groups of initial continuous electrical operating parameters of the electrical control cabinet;
[0032] P34: Traverse the multiple groups of initial continuous electrical operating parameters of the electrical control cabinet to extract the central values of the electrical operating parameters to generate the multiple groups of continuous electrical operating parameters of the electrical control cabinet.
[0033] Optionally, interact with the target electrical control cabinet and receive the electrical operating parameters of the electrical control cabinet, that is, the pre-configured operating parameters of the target electrical control cabinet, such as operating voltage, operating current, operating temperature, protection level, etc. The electrical operating parameters of the electrical control cabinet include multiple groups of electrical operating parameters at multiple different time periods. Exemplarily, the electrical operating parameters of the electrical control cabinet include the electrical operating parameters of the first sequential electrical control cabinet and the electrical operating parameters of the second sequential electrical control cabinet, and the first time sequence and the second time sequence are two adjacent time periods.
[0034] Further, the deviation distance between the electrical operating parameters in any two adjacent time series is evaluated. Exemplarily, the deviation distance between the electrical operating parameters of the first-time-series electrical control cabinet and the second-time-series electrical control cabinet is evaluated. First, the attributes of the electrical operating parameters are traversed, and a corresponding attribute deviation threshold, that is, the maximum parameter deviation, such as the pressure deviation threshold, is configured for each electrical parameter. Further, the deviation between each electrical parameter in the electrical operating parameters of the first-time-series electrical control cabinet and the second-time-series electrical control cabinet is calculated, such as calculating the operating current deviation and operating voltage deviation between the first time series and the second time series, and the corresponding electrical operating parameter deviation modulus is generated. Similarly, the deviation between the electrical operating parameters in any two adjacent time series is calculated using the same method, and multiple electrical operating parameter deviation moduli are generated. Further, the moduli of the electrical operating parameter deviation moduli that are greater than or equal to the attribute deviation threshold are extracted, and the modal distance coefficient of the corresponding operating parameter is calculated through the average value of the moduli.
[0035] Further, taking the modal distance threshold as the clustering criterion, the adjacent time series clustering of the electrical operating parameters of the electrical control cabinet is performed with reference to the modal distance coefficient. The electrical operating parameters with the same modal distance coefficient are classified into one category, and the electrical operating parameters with different modal distance coefficients are classified into different categories, that is, the electrical operating parameters of adjacent time series with smaller deviations are classified into one category, and multiple groups of initial continuous electrical control cabinet electrical operating parameters are generated. Each group of initial continuous electrical control cabinet electrical operating parameters contains multiple operating parameter sequences with different attributes.
[0036] Further, the central tendency analysis is respectively performed on the multiple groups of initial continuous electrical control cabinet electrical operating parameters. First, the discrete values are identified through the outlier analysis method. For example, the quartile range method is used to screen out the outliers in the electrical operating parameters of each attribute in any group of initial continuous electrical control cabinet electrical operating parameters and delete them. Then, the mean value of the remaining values is calculated to obtain the central value of the electrical operating parameters of each attribute. By analogy, the central values of the electrical operating parameters of each attribute in the multiple groups of initial continuous electrical control cabinet electrical operating parameters are obtained, and the multiple groups of continuous electrical control cabinet electrical operating parameters are generated.
[0037] P40: In combination with the characteristic temperature of the warehouse, the multiple groups of continuous electrical control cabinet electrical operating parameters are sequentially retrieved, and the air pressure change prediction channel is activated for training to generate an air pressure change prediction curve;
[0038] Further, as Figure 3 shown, step P40 of the embodiment of the present application further includes:
[0039] P41: Based on big data, a warehouse temperature monitoring data set, an electrical control cabinet electrical operating parameter record data set, an initial air pressure record data set, and an air pressure change curve monitoring data set are collected;
[0040] P42: Based on the long short-term memory neural network, build the topological structure of the air pressure change prediction channel;
[0041] P43: Construct the loss function for air pressure change prediction:
[0042]
[0043] where LOSS represents the training loss value, y ij represents the predicted air pressure value at the j-th moment of the output value of the i-th training, y ij0 is the monitored air pressure data at the j-th moment of the air pressure change curve monitoring data set of the i-th training, M represents the pre-configured prediction duration, and N represents the number of training times for statistical training loss;
[0044] P44: According to the air pressure change prediction loss function, retrieve the warehouse temperature monitoring data set, the electrical control cabinet electrical working parameter record data set, the initial air pressure record data set, and the air pressure change curve monitoring data set to configure the topological structure of the air pressure change prediction channel, and generate the air pressure change prediction channel;
[0045] In a possible embodiment of the present application, based on big data, collect the electrical working parameters of the intelligent warehouse electrical control cabinet, obtain the warehouse temperature monitoring data set, the electrical control cabinet electrical working parameter record data set, the initial air pressure record data set, and the air pressure change curve monitoring data set. Further, based on the long short-term memory neural network, build the topological structure of the air pressure change prediction channel. The long short-term memory neural network is a type of time-recursive neural network with long-term memory ability, and its network structure consists of one or more units with forget and memory functions, which is suitable for processing and predicting important events with very long intervals and delays in time series.
[0046] Further, construct the loss function for air pressure change prediction:
[0047]
[0048] where LOSS represents the training loss value, y ij represents the predicted air pressure value at the j-th moment of the output value of the i-th training, y ij0The air pressure monitoring data at the j-th moment of the air pressure change curve monitoring dataset for the i-th training. M represents the pre-configured prediction duration, and N represents the number of training times for statistically calculating the training loss. According to the air pressure change prediction loss function, the warehouse temperature monitoring dataset, the electrical cabinet electrical working parameter record dataset, the initial air pressure record dataset, and the air pressure change curve monitoring dataset are retrieved as training data to train the air pressure change prediction channel topology structure, and the topology structure is adjusted according to the output result until the training loss value meets the preset loss requirement, indicating that the air pressure change prediction channel topology structure converges, and the air pressure change prediction channel is generated.
[0049] P45: According to the air pressure change prediction channel, receive the characteristic temperature of the warehouse and the constant air pressure of the electrical cabinet, and sequentially retrieve the multiple groups of continuous electrical cabinet electrical working parameters for training to generate the air pressure change prediction curve.
[0050] Further, step P45 of the embodiment of the present application further includes:
[0051] P45-1: The multiple groups of continuous electrical cabinet electrical working parameters include the first group of electrical cabinet electrical working parameters and the first working duration, the second group of electrical cabinet electrical working parameters and the second working duration, until the L-th group of electrical cabinet electrical working parameters and the L-th working duration;
[0052] P45-2: Activate the air pressure change prediction channel, receive the characteristic temperature of the warehouse, the constant air pressure of the electrical cabinet, and the first group of electrical cabinet electrical working parameters to perform the prediction for the first working duration, and generate the first air pressure change prediction curve, where the first air pressure change prediction curve has the first curve end point air pressure;
[0053] P45-3: Activate the air pressure change prediction channel, receive the characteristic temperature of the warehouse, the first curve end point air pressure, and the second group of electrical cabinet electrical working parameters to perform the prediction for the second working duration, and generate the second air pressure change prediction curve, where the second air pressure change prediction curve has the second curve end point air pressure;
[0054] P45-4: Repeat the iteration until the L-th air pressure change prediction curve is generated;
[0055] P45-5: Connect the first air pressure change prediction curve, the second air pressure change prediction curve until the L-th air pressure change prediction curve in sequence to generate the air pressure change prediction curve.
[0056] Exemplarily, through the air pressure change prediction channel, the characteristic temperature of the warehouse and the constant air pressure of the electric control cabinet are received, and the multiple sets of continuous electrical working parameters of the electric control cabinet are sequentially retrieved as training data to perform training on the air pressure change prediction curve. The multiple sets of continuous electrical working parameters of the electric control cabinet include the first set of electrical working parameters of the electric control cabinet and the first working duration, the second set of electrical working parameters of the electric control cabinet and the second working duration, until the Lth set of electrical working parameters of the electric control cabinet and the Lth working duration, a total of L sets of electrical working parameters of the electric control cabinet.
[0057] Further, activate the air pressure change prediction channel, and use the characteristic temperature of the warehouse, the constant air pressure of the electric control cabinet, and the first set of electrical working parameters of the electric control cabinet. Based on the first working duration, perform air pressure change prediction, and generate a first air pressure change prediction curve according to the air pressure prediction result. The first air pressure change prediction curve has a first curve end air pressure, which can be used as the starting air pressure of the second air pressure change prediction curve. Similarly, through the air pressure change prediction channel, receive the characteristic temperature of the warehouse and the first curve end air pressure, and use the second set of electrical working parameters of the electric control cabinet to perform air pressure change prediction based on the second working duration to generate a second air pressure change prediction curve. And so on, repeat the iteration until the Lth air pressure change prediction curve is generated. Finally, connect the first air pressure change prediction curve, the second air pressure change prediction curve until the Lth air pressure change prediction curve in chronological order to generate the air pressure change prediction curve.
[0058] P50: Monitor the internal air pressure of the electric control cabinet and construct a reference curve for air pressure change;
[0059] Specifically, through the air pressure monitoring device installed inside the electric control cabinet, the change of the internal air pressure of the electric control cabinet is monitored in real time, and the air pressure monitoring data within a period of time is obtained, and a reference curve for air pressure change is drawn, that is, the actual air pressure change curve inside the electric control cabinet, which can be used to verify the accuracy of air pressure prediction data.
[0060] P60: Perform deviation analysis on the air pressure change prediction curve and the reference curve for air pressure change to generate an air pressure control deviation coefficient;
[0061] Further, step P60 of the embodiment of the present application further includes:
[0062] P61: Configure an air pressure deviation threshold, and count the ratio of the number of air pressures greater than or equal to the air pressure deviation threshold in the air pressure change prediction curve and the reference curve for air pressure change, which is set as the air pressure control deviation coefficient.
[0063] Optionally, perform air pressure deviation analysis on the air pressure change prediction curve and the air pressure change reference curve, that is, calculate the difference between the predicted air pressure and the actual air pressure. First, configure the air pressure deviation threshold, that is, the minimum deviation between the predicted air pressure and the actual air pressure. Further, count the number of air pressure values in the air pressure change prediction curve and the air pressure change reference curve where the air pressure deviation is greater than or equal to the air pressure deviation threshold, and calculate the proportion of the number of air pressure values to the total number of air pressure values, which is used as the air pressure control deviation coefficient to reflect the control deviation of the system.
[0064] P70: Add the air pressure control deviation coefficient to the explosion-proof detection result of the electric control cabinet.
[0065] Further, step P70 of the embodiment of the present application further includes:
[0066] P71: When the air pressure control deviation coefficient is less than or equal to the control deviation coefficient threshold, generate a stable air pressure control identifier for the electric control cabinet and add it to the explosion-proof detection result of the electric control cabinet;
[0067] P72: When the air pressure control deviation coefficient is greater than the control deviation coefficient threshold, perform multiple air pressure control verifications on the electric control cabinet with the warehouse characteristic temperature and the constant air pressure of the electric control cabinet as constraints, and generate electric control cabinet air pressure control record data, where the electric control cabinet air pressure control record data includes the recorded values of the electrical working parameters of the electric control cabinet, the recorded values of the air pressure control deviation coefficient, and the recorded values of the air pressure deviation vector;
[0068] P73: Use the recorded values of the electrical working parameters of the electric control cabinet and the air pressure control deviation coefficient as inputs and the recorded values of the air pressure deviation vector as outputs to construct an air pressure deviation vector fitting component;
[0069] P74: Collaborate with the air pressure deviation vector fitting component and the air pressure change prediction channel to perform air pressure control on the electric control cabinet.
[0070] It should be understood that adding the air pressure control deviation coefficient to the explosion-proof detection result of the electric control cabinet can be used for verifying the accuracy of air pressure prediction and as a reference for adjusting the air pressure control parameters in the future. When the air pressure control deviation coefficient is less than or equal to the control deviation coefficient threshold, it indicates that the air pressure control deviation of the system is within the allowable range, and a stable air pressure control identifier for the electric control cabinet is generated and added to the explosion-proof detection result of the electric control cabinet to feedback that the current explosion-proof detection result of the electric control cabinet is in a stable state and no parameter adjustment is required in the future.
[0071] Optionally, when the air pressure control deviation coefficient is greater than the control deviation coefficient threshold, it indicates that the air pressure control deviation of the current system exceeds the allowable range and there is a safety risk. Therefore, it is necessary to calibrate and compensate the predicted air pressure value through the auxiliary module. Exemplarily, with the constraint of the warehouse characteristic temperature and the constant air pressure of the electric control cabinet, the air pressure control results of the electric control cabinet are verified multiple times, that is, the control deviation of multiple air pressure control results is evaluated to generate the electric control cabinet air pressure control record data. The electric control cabinet air pressure control record data includes the recorded value of the electric control cabinet electrical working parameters, the recorded value of the air pressure control deviation coefficient, and the recorded value of the air pressure deviation vector. The recorded value of the air pressure deviation vector can reflect whether the air pressure deviation direction is too large or too small.
[0072] Further, using the recorded value of the electric control cabinet electrical working parameters and the air pressure control deviation coefficient as input data, and the recorded value of the air pressure deviation vector as output data, combined with machine learning, such as a BP neural network, a air pressure deviation vector fitting component is constructed, and supervised training is performed through the input data and output data until the output of the air pressure deviation vector fitting component converges to obtain the air pressure deviation vector fitting component. Using the air pressure deviation vector fitting component as an auxiliary module, the output result of the air pressure change prediction channel is calibrated and compensated to realize the air pressure control of the electric control cabinet and obtain a good explosion-proof effect.
[0073] In summary, the embodiments of the present application at least have the following technical effects:
[0074] The present application receives the electrical working parameters of the electric control cabinet, generates multiple groups of continuous electrical working parameters of the electric control cabinet, combines the warehouse characteristic temperature, trains to generate an air pressure change prediction curve, monitors the internal air pressure of the electric control cabinet, constructs an air pressure change reference curve, performs deviation analysis on the air pressure change prediction curve and the air pressure change reference curve, generates an air pressure control deviation coefficient, and adds it to the explosion-proof detection result of the electric control cabinet.
[0075] It achieves the technical effect of improving the explosion-proof performance of the electric control cabinet by dynamically predicting the internal air pressure change of the electric control cabinet and dynamically adjusting the real-time air pressure.
