[0062] Reference Figure 5 , Figure 5 It is an MCU peripheral circuit that provides logic control for the entire system and is the heart of the entire system. This module uses Fourier transform and wavelet transform algorithms to perform advanced data analysis to extract advanced features from temperature and humidity data. Data processing helps create a predictive model that correlates the temperature, humidity, and conductive properties of insulating materials. In this embodiment, the STM32F103C8T6 chip is used.

[0065] Reference Figure 8 , Fig. 9 , Fig.10 as well as Fig.11 These are the basic circuits of the STM32F103C8T6 chip. Figure 8 It is the reset circuit of the STM32F103C8T6 chip. When receiving a signal, it can reset the chip to return to its initial state. Fig. 9 The crystal oscillator circuit of the STM32F103C8T6 chip is one of the basic circuits of the chip, ensuring that the chip runs at the correct rhythm; Fig.10 It is the test circuit of the chip, used to transmit debugging information and program data; Fig.11 The middle one is the voltage stabilizing circuit of STM32F103C8T6 chip, which is also the basic circuit of STM32F103C8T6 chip. It provides stable voltage for STM32F103C8T6 chip and ensures the normal operation of the chip.

[0066] Reference Fig.12 , which is the interface circuit of the chip STM32F103C8T6, where U4 is the interface of the device, and the model used is ZX-XH2.54-4PZZ. Its 2nd and 3rd pins are the input port and output port of the data respectively. One end is connected to the PA0 and PA10 ports of the chip, and the other end is used to connect the temperature and humidity sensor to transmit the device information to the internal processing of the chip.

[0067] Reference Fig.13 , which is the circuit for controlling the fan, where CN5 is the interface for directly connecting the hardware device of the fan body, and the other end is connected to the power supply and the PA0-WKUP interface of the chip through a SS8050 transistor model to control the rotation of the fan through the chip.

[0068] Reference Fig.14, which is the control circuit of the dehumidifier, where P1 and P2 are two interfaces respectively, P1 is used to connect the power supply, P2 is connected to the constant temperature dehumidifier 101b, the constant temperature dehumidifier 101b is connected to the K1 relay of HF41F / 12-ZS type, and the relay K1 is connected to the PB12 port of the chip. The constant temperature dehumidifier 101b is controlled by the chip to work. When the ambient humidity exceeds the set value, the dehumidification temperature control mode is turned on.

The operation of the buzzer is directly controlled by the chip. When the constant temperature dehumidifier 101b works for a long time but still cannot reduce the humidity to the safety threshold, an alarm is issued.

[0071] Example 3, reference Figures 1 to 17 , which is the third embodiment of the present invention, and further provides a constant temperature and humidity control method. It includes S1: collecting temperature and humidity data inside the tool box;

[0072] S2: Extract periodic and / or short-term characteristics of temperature and humidity data;

[0073] S3: Calculate the conductivity of the measuring component according to the characteristics;

[0074] Preferably, for most metal conductors, their conductivity decreases when the temperature rises. This is because the increase in temperature intensifies the thermal vibration of atoms in the metal, causing more scattering of electrons during conduction, thereby increasing resistance; when humidity increases, the surface of the insulator may absorb moisture to form a thin layer of water film. Water has a certain conductivity, which will reduce the surface resistance of the insulator, thereby increasing the risk of leakage. For some porous insulating materials, moisture may also penetrate into the material, further reducing its insulation performance.

[0075] S4: Determine whether the temperature and humidity exceed the standard at this time;

[0076] If yes, then S5: adjust the temperature and humidity inside the box, if no, then return to S1;

[0077] S6: Determine whether the temperature and humidity continue to drop to the threshold value;

[0078] If yes, then return to S1, if no, then S6: alarm.

[0079] Periodic feature extraction uses Fourier transform to extract temperature and humidity features.

[0080] Preferably, humidity data usually changes over time and may contain periodic fluctuations, such as diurnal or seasonal changes. Fourier transform can be used to convert humidity time series data into frequency domain representation in order to identify potential periodic features. By analyzing the frequency components of humidity, periodic fluctuations of high humidity and low humidity are found. Humidity data may contain noise, and Fourier transform can remove high-frequency noise to make the data smoother.

[0081] Short-term features include temperature and humidity features extracted using wavelet transforms.

[0082] Model building through wavelet transform: Wavelet transform is used to analyze the short-term characteristics of humidity data. Wavelet analysis can decompose the time series data of humidity to identify the change patterns on different time scales. The results of wavelet analysis can be used as feature input to further improve the accuracy of the prediction model. Through these models, the conductive properties of insulating materials at different humidity levels can be effectively predicted, thereby maintaining the insulating properties of the materials in real-time monitoring.

[0083] The MCU peripheral circuit, that is, the circuit part in Example 2, provides logic control for the entire system and is the heart of the entire system. This module performs advanced data analysis using Fourier transform and wavelet transform algorithms to extract advanced features from temperature and humidity data. Data processing helps create a predictive model that correlates the temperature, humidity, and conductive properties of insulating materials.

[0084] Based on the sampled signal time series, the microcontroller MCU performs spectrum analysis of the humidity signal through fast Fourier transform FFT to obtain the frequency components of the signal and accurately reflect the dynamic characteristics of the humidity value.

[0085] The fast Fourier transform FFT process is as follows:

[0086] FFT is a fast algorithm of DFT, which can convert the signal from time domain to frequency domain and analyze the frequency components of the signal.

[0087] Given a discrete signal x(n) of length N, the formula for its DFT is:

[0088] For a continuous-time signal x(t), its Fourier transform is defined as:

[0089]

[0090] For discrete-time signals (DFT), it is defined as:

[0091]

[0092] in:

[0093] N is the number of sampling points of the signal;

[0094] x(n) is the signal sequence in the time domain.

[0095] X[k] is the frequency domain signal.

[0096] K is the frequency component index.

[0097] j is the imaginary unit.

[0098] FFT is a fast method to calculate the above formula, and the time complexity is O(N 2 ) is reduced to O(NlogN).

[0099] Algorithm steps:

[0100] Read the discrete humidity signal x(n).

[0101] Apply FFT to convert the signal from time domain to frequency domain and obtain the spectrum X[k].

[0102] The frequency characteristics of the signal can be understood by analyzing the amplitude and phase information in X[k].

[0103] The formula of wavelet transform is relatively complicated, and is generally obtained by using the mother wavelet function Scaling and translation are performed to obtain a set of wavelet basis functions:

[0104]

[0105] Where a is the scale factor and b is the translation factor. The continuous wavelet transform of the signal x(t) is defined as:

[0106]

[0107] Processed data and feature extraction enable the chip to evaluate changes in conductive properties based on environmental conditions. The system can determine if conditions are within safe limits.

[0108] In summary, the temperature and humidity are initially collected through the chip STM32F103C8T6, and then Fourier transform and wavelet transform are used to analyze the temperature and humidity data, extract more advanced features, and establish a relationship model between temperature, humidity and the conductivity of insulating materials through the conductivity of the insulating rod input inside the chip. The established model is applied to the actual environment, and the conductivity of the insulating material is predicted by real-time monitoring of temperature and humidity data. The desired conductivity of the insulating rod is calculated through the temperature threshold set on the screen, and a comparison is performed to ensure that the conductivity of the insulating rod is always at the preset value in the box environment, and an alarm can be issued when the box environment is unbalanced and cannot be automatically balanced.
