[0028] The monitoring and alarm module is used to alarm abnormal situations according to the data analysis results and provide a real-time monitoring interface. The monitoring and alarm module consists of monitoring software, an alarm system, and a display screen.

[0029] The data acquisition module monitors the mine environmental parameters in real time through sensors and converts analog signals into digital signals. The data acquisition card collects these signals and performs preliminary processing.

[0030] The data collected by the data transmission module is sent to the ground monitoring center through the mine intrinsically safe transmission substation using Ethernet, RS485 or Wi-Fi, LoRa communication methods.

[0031] The data processing module receives data through the ground server, analyzes and calculates it through the data processing software, and stores the data in the database for historical data analysis and query.

[0032] The monitoring and alarm module uses monitoring software to display the mine environmental parameters in real time. Once an abnormal situation is detected, the alarm system is immediately triggered. The alarm can be made through sound, light signal or mobile notification.

[0033] The specific steps of the data processing module are:

[0034] S1: Data receiving, receiving data stream from the data transmission module;

[0035] S2: Data preprocessing: first, denoising, using filtering algorithms (such as sliding average filtering, Kalman filtering, etc.) to remove random noise in the data; then calibrating, calibrating the data according to the calibration parameters of the sensor to ensure the accuracy of the data; then filling in missing values, using interpolation and other methods to fill in missing data caused by transmission interruption and other reasons;

[0039] S6: Decision support: Based on the analysis results, provide decision support for the adjustment and optimization of the mine system.

[0040] Take the wind speed sensor as an example:

[0041] The workflow is as follows: Data acquisition: The wind speed sensor is installed at an appropriate location in the mine to monitor the wind speed underground in real time. When the wind flows through the sensor, the sensing element in the sensor (such as a hot wire or an impeller) generates a signal proportional to the wind speed. This analog signal is converted into a digital signal by a built-in signal converter for easy transmission and processing. Data transmission: The converted digital signal is sent to the ground monitoring center through a mine intrinsically safe transmission substation via wired (such as RS485 communication line) or wireless (such as Wi-Fi, Bluetooth). Data processing: After receiving the wind speed data, the server at the ground monitoring center uses special data processing software for analysis. The software may calculate statistical information such as average wind speed, maximum wind speed, and minimum wind speed. Monitoring and alarm: The monitoring software displays the wind speed data in real time and compares it with the preset safety standards. If the wind speed exceeds or falls below the safety range, the system will trigger an alarm.

[0042] The data acquisition module is used to monitor and accurately measure wind speed in real time to ensure the reliability and real-time nature of the data. The data transmission module is used to safely and stably transmit wind speed data to the ground monitoring center to ensure the continuity and integrity of the data. The data processing module is used to process wind speed data to generate valuable statistical and analytical results to provide decision support for mine ventilation management. The monitoring and alarm module is used to monitor wind speed changes in real time and issue an alarm in a timely manner when the wind speed is abnormal to ensure the safety of mine workers.

[0043] Processing and analysis methods include:

[0044] Signal processing technology: time domain analysis, directly analyzing the time series of wind speed signals, such as observing the changes in wind speed through waveform graphs; frequency domain analysis, using Fourier transform and other methods to analyze the frequency components of wind speed signals.

[0045] Statistical analysis: Descriptive statistics, calculating the mean, median, mode, variance, etc. of wind speed data; hypothesis testing, testing whether the wind speed data conforms to specific statistical hypotheses through methods such as t-test and chi-square test.

[0046] Data mining technology: pattern recognition, identifying specific patterns in wind speed data, such as periodic changes, outliers, etc.; predictive analysis, using time series analysis, machine learning and other methods to predict future wind speed changes.

[0047] Visualization technology: Graphic display, using line graphs, bar graphs, pie charts, etc. to display the statistical results of wind speed data; real-time monitoring, using dynamically updated charts or dashboards to monitor wind speed status in real time.

[0048] Through these steps and methods, the data processing module can ensure the accuracy and availability of wind speed data, provide a scientific basis for mine ventilation management, and thus ensure safe production in mines.

[0049] This system has many advantages: 1. Real-time, real-time monitoring of wind speed, rapid response to wind speed changes, and timely adjustment of the ventilation system; 2. Accuracy, high-precision wind speed measurement to ensure the scientificity and effectiveness of ventilation management; 3. Safety, through real-time monitoring and alarm systems, to prevent mine accidents caused by improper wind speed; 4. Stability, the design of the mine intrinsically safe transmission substation and sensor meets the mine intrinsic safety requirements and can work stably in harsh environments; 5. Easy maintenance, the system design is simple, easy to install and maintain, and reduces long-term operating costs.

[0050] Through the specific application examples of wind speed sensors, we can see the important role of the real-time data analysis system of the mine intrinsically safe transmission substation in mine safety production, especially in ventilation management.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
