[0075] Controller 6 is installed outside the concrete lining 1 of the shaft, and controller 6 is electrically connected to solenoid valve 4 and electromagnetic flow meter 5.

[0077] As an optional implementation, the temperature and humidity sensing unit includes a plurality of temperature and humidity sensors 7, which are evenly arranged along the height direction of the curing chamber, and the temperature and humidity sensors 7 are electrically connected to the controller 6.

[0078] As an optional implementation, the fault diagnosis alarm component includes:

[0079] The current sensor 8 is electrically connected to the solenoid valve 4 and is used to detect the current signal of the solenoid valve 4.

[0080] Fault detector 10 is electrically connected to current sensor 8;

[0081] Buzzer 9 is electrically connected to fault detector 10.

[0082] Temperature and humidity sensors 7 are installed at different heights inside the curing chamber; water pump 2 is installed on the upper part of the vertical shaft lining concrete 1, water pump 2 is electrically connected to control panel 11, and the water output of water pump 2 is controlled by control panel 11. The water outlet pipe 3 of water pump 2 extends into automatic guide rail system 13 and is connected to spray device 12.

[0083] The controller 6 is connected to all temperature and humidity sensors 7, solenoid valves 4 and electromagnetic flow meters 5; the controller 6 is connected to the control panel 11 and controls the water output of the water pump 2 based on the temperature and humidity data fed back by the temperature and humidity sensors 7 in the curing chamber.

[0084] When the temperature and humidity sensor 7 detects that the temperature of the vertical shaft lining concrete 1 is higher than the set threshold T and the humidity is lower than the set threshold RH, the controller 6 adjusts the opening of the solenoid valve 4 according to the difference between the temperature and humidity of the vertical shaft lining concrete 1 and the threshold, so as to adjust the water flow rate obtained from the water outlet pipe 3 by the spray pipe 14, and the water is sprayed out from the nozzle 15 to achieve the function of humidifying and cooling the concrete in the vertical shaft.

[0085] Furthermore, when the electromagnetic flowmeter 5 detects that the water flow rate reaches the spray volume V, it sends a signal to the controller 6 to control the solenoid valve 4 to shut off; initial water output... The calculation method is as follows:

[0086]

[0087] in, Let the radius of the shaft be . The depth of the concrete lining of the shaft. This refers to the concrete moisture content coefficient. Initially, input the well depth on control panel 11. ,radius The output water of pump 2 is controlled by parameters such as these.

[0088] The solenoid valve 4 is equipped with a current sensor 8, which is used to collect the current signal of the solenoid valve 4 and is connected to the fault detector 10 to transmit the current signal into it. The fault detector 10 is connected to the buzzer 9.

[0089] The current sensor 8 detects the current signal of the solenoid valve 4, and the fault detector 10 processes and diagnoses the fault. If a fault occurs, the buzzer 9 will sound an alarm, which can promptly notify the mine personnel to intervene and avoid further damage.

[0090] Furthermore, the specific fault diagnosis method is as follows:

[0091] First, the solenoid valve current signal acquired by the PLC is input into the preprocessing module. The signal is first decomposed into 5 levels of discrete wavelet decomposition using the Daubechies4 (db4) wavelet basis to extract the high-frequency detail coefficients. Then, SURE adaptive soft thresholding is used for denoising. Finally, the signal is reconstructed together with the unthresholded low-frequency coefficients to recover the main components. Next, linear normalization is performed on the reconstructed signal according to...

[0092]

[0093] The amplitude is compressed to the [0,1] interval to eliminate the influence of the unit and speed up the convergence of subsequent algorithms;

[0094] Secondly, the normalized current signal enters the Variational Mode Decomposition (VMD) module, which decomposes it into several Intrinsic Mode Functions (IMFs). Typically, five modes are set to cover the main frequency bands of the signal. For each IMF, its energy ratio (i.e., the proportion of energy of each IMF to the total energy), center frequency, and spectral entropy (measuring the uncertainty of the power spectrum distribution) are calculated to obtain time-frequency feature vectors of several dimensions, which comprehensively reflect the energy distribution and variation of the signal in different frequency bands and provide input information for the classifier.

[0095] Finally, using historical labeled data, the aforementioned time-frequency features and the corresponding solenoid valve states are input into a support vector machine (SVM) classifier for training. Through cross-validation and hyperparameter optimization, the optimal kernel model is selected, and its support vectors, dual coefficients, biases, and kernel parameters are extracted. After training, these model parameters are converted into an embedded, callable inference module and integrated into the MCU environment. During online operation, the PLC collects the current every 100ms and sequentially performs preprocessing → VMD feature extraction → SVM inference. If the inference result is a "fault" class, the PLC outputs a digital signal to drive the buzzer and alarm light, issuing a fault alarm in real time.

[0096] As an optional implementation, a cross-shaped partition wall is provided in the middle of the vertical shaft lining concrete 1, which divides the vertical shaft lining concrete 1 into four circumferentially spaced curing chambers.

[0097] Automatic guide rail system 13 is installed in each of the four sector-shaped areas of the vertical shaft lining concrete 1.

[0098] Example 2:

[0099] refer to Figure 4 The difference between this embodiment and Embodiment 1 is that the Z-axis lifting guide rail 18 includes:

[0100] Slide rail 1801 is fixed to the inner wall of the curing chamber;

[0101] The threaded rod 1802 is rotatably mounted within the slide rail 1801;

[0102] Motor 1803 is fixedly connected to the top of slide rail 1801, and the output shaft of motor 1803 is connected to threaded rod 1802.

[0103] The threaded block 1804 is threadedly engaged with the threaded rod 1802. The threaded block 1804 slides vertically within the slide rail 1801. The threaded block 1804 is used to fix the X-axis fixed guide rail 16 and the Y-axis fixed guide rail 17. Two diagonal braces 1805 are fixed to one end of the threaded block 1804. The other end of the diagonal braces 1805 is fixed to the corresponding X-axis fixed guide rail 16 / Y-axis fixed guide rail 17.

[0104] The diagonal brace 1805 provides support and fixation for the X-axis fixed guide rail 16 and the Y-axis fixed guide rail 17. When lifting is required, the motor 1803 drives the threaded rod 1802 to rotate, causing the threaded block 1804 to move up along the slide rail 1801 under the action of the thread.
