[0024] The excavation control module is used to control the excavation equipment according to the excavation strategy.

[0025] The cloud data server is used to generate a tunneling strategy according to the tunneling target location, including: The cloud data server obtains the power control parameters of the excavation equipment according to the set target excavation speed and the excavation equipment parameters; and obtains the estimated concentration of the environmental monitoring target according to the excavation speed, and obtains the equipment operating parameters of the environmental control device; the power control parameters of the excavation equipment, the equipment operating parameters of the environmental control device and the target excavation parameters constitute the excavation strategy.

[0026] The excavation data acquisition module is used to collect excavation data of the excavation process, wherein the excavation data includes excavation speed and environmental parameters; The excavation speed is the moving speed of the excavation equipment per unit time, and the speed difference with the target excavation speed is obtained according to the excavation speed; the environmental parameters are the concentration data of the preset environmental monitoring target and the change of the concentration data.

[0027] The said modification of the excavation strategy according to the excavation data comprises: If the concentration of the environmental monitoring target is less than the concentration threshold, and the difference between the excavation speed and the target excavation speed is less than the set difference threshold, the excavation strategy continues to be executed; otherwise, the equipment operating parameters of the environmental control device are adjusted according to the concentration of the environmental monitoring target to obtain a revised excavation strategy, or the excavation speed is adjusted according to the concentration of the environmental monitoring target to obtain a revised excavation strategy.

[0028] The method of adjusting the equipment operating parameters of the environmental control device according to the concentration of the environmental monitoring target to obtain a revised excavation strategy, or adjusting the excavation speed according to the concentration of the environmental monitoring target to obtain a revised excavation strategy, includes: If the concentration of the environmental monitoring target is greater than the concentration threshold, and the difference between the excavation speed and the target excavation speed is less than the set difference threshold, the excavation speed of the excavation equipment is adjusted according to the concentration change per unit time of the environmental monitoring target to obtain the adjusted excavation speed, and the excavation speed of the excavation strategy is adjusted to the adjusted excavation speed to obtain the revised excavation strategy; If the concentration of the environmental monitoring target is greater than the concentration threshold, and the difference between the excavation speed and the target excavation speed is greater than the set difference threshold, the equipment operating parameters of the environmental control device are adjusted according to the concentration change per unit time of the environmental monitoring target to obtain the adjusted equipment operating parameters, the equipment operating parameters of the excavation strategy are adjusted to the adjusted equipment operating parameters, and the excavation speed of the excavation strategy is adjusted to the current excavation speed to obtain the revised excavation strategy.

[0029] The method of adjusting the excavation speed of the excavation equipment according to the concentration change per unit time of the environmental monitoring target to obtain the adjusted excavation speed includes: According to the change in concentration per unit time, the increase per unit time of the environmental monitoring target is obtained. According to the increase per unit time of the environmental monitoring target discharged by the environmental control device, the required discharge time is obtained. According to the discharge time and the excavation speed, the excavation length is obtained. The adjusted excavation speed is: The unit excavation length is the length of excavation per unit time according to the excavation speed.

[0030] The device operating parameters of the environmental control device are adjusted according to the concentration change per unit time of the environmental monitoring target to obtain the adjusted device operating parameters, including: According to the change in concentration per unit time, the increase in the environmental monitoring target per unit time is obtained. According to the power required by the environmental control device to discharge the increase in the environmental monitoring target per unit time, the power in the equipment operating parameters of the environmental control device in the excavation strategy is corrected to the sum of the original power and the required power.

[0031] The intelligent control system of a pit excavation device described in the present invention mainly includes the following core modules: Excavation data acquisition module: This module is responsible for collecting key data in the excavation process in real time, including but not limited to excavation speed, environmental parameters (such as dust concentration, gas concentration, temperature, humidity, etc.). These data are acquired through high-precision sensors and directly transmitted to the data processing module for analysis. In particular, the excavation data acquisition device is subdivided into environmental data acquisition devices and excavation data acquisition devices to ensure the comprehensiveness and accuracy of data collection.

[0032] Cloud data server: As the "brain" of the system, the cloud data server receives data from the excavation site, and uses big data analysis and machine learning algorithms to intelligently generate initial excavation strategies based on geological information of the excavation target location, historical excavation data, etc. At the same time, the server can also dynamically adjust the excavation strategy based on real-time feedback of excavation data to ensure the efficiency and safety of excavation operations.

[0033] Excavation control module: Based on the excavation strategy provided by the cloud data server, the excavation control module accurately controls the operating status of the excavation equipment, including excavation speed, power distribution, etc., to ensure that the excavation operation is carried out according to the optimal strategy.

[0034] Environmental control device: In response to environmental problems that may be encountered during excavation, such as excessive dust and water accumulation, environmental control devices (including ventilation devices, drainage devices, etc.) are automatically adjusted according to the analysis results of the data processing module to maintain a good working environment. These devices are closely connected with the data processing module to achieve real-time monitoring and intelligent control of environmental parameters.

[0035] Data processing module: As the information processing center of the system, the data processing module is responsible for receiving, integrating and analyzing data from various modules, providing decision-making basis for the cloud data server, and directly controlling the operation of the tunneling control module and environmental control device.

[0036] Communication module: ensures efficient and stable communication between all components of the system, and enables seamless data transmission whether it is a tunneling site deep underground or a remote cloud server.

[0037] How it works Intelligent generation and modification of tunneling strategies Initial strategy generation: The cloud data server calculates the optimal excavation equipment power control parameters and environmental control device operating parameters through an algorithm model based on the geological characteristics of the excavation target location, equipment performance parameters and the preset excavation target speed, and forms an initial excavation strategy.

[0038] Dynamic correction: During the excavation process, the excavation data acquisition module continuously collects data and uploads it to the cloud. The server automatically determines whether the excavation strategy needs to be adjusted based on the comparison of real-time data (especially the concentration data of environmental monitoring targets and excavation speed) with the preset threshold. For example, when the dust concentration exceeds the safety threshold or the excavation speed deviates too much from the target, the system will adjust the power of the ventilation device, excavation speed, etc. accordingly to ensure safe and efficient operation.

[0039] Environmental Adaptive Control Intelligent ventilation and drainage adjustment: The environmental control device automatically adjusts the ventilation volume and drainage efficiency according to the analysis results of the data processing module, effectively responding to the challenges brought by environmental changes during the excavation process. For example, the ventilation volume is increased when the dust concentration rises, or the drainage is strengthened when the groundwater level rises, to ensure the comfort and safety of the working environment.

[0040] Intelligent adjustment of excavation speed and equipment power The system can dynamically adjust the excavation speed and equipment power according to the concentration changes of the environmental monitoring target, achieving a balance between excavation efficiency and environmental protection. In particular, when encountering emergencies (such as a sudden increase in gas concentration), the system can respond quickly, reduce the excavation speed or suspend operations, while enhancing ventilation to ensure personnel safety.

[0041] Example 1: Application of intelligent control system in coal mine excavation In a large coal mine project, the intelligent control system of the pit excavation device described in the present invention is deployed. The system collects key data in the excavation process in real time through the excavation data acquisition module, including environmental parameters such as excavation speed, gas concentration, dust concentration, and the operating status information of the excavation equipment. These data are immediately transmitted to the data processing module for analysis and processing.

[0042] Tunneling strategy generation and modification: Generation of initial excavation strategy: The cloud data server generates an initial excavation strategy based on the excavation target position of the coal mine, the set target excavation speed, and the specific parameters of the excavation equipment (such as power, efficiency, etc.), including the power control parameters of the excavation equipment and the operating parameters of the environmental control devices (such as ventilation devices).

[0043] Strategy modification during excavation: As excavation progresses, the excavation data acquisition module continues to collect data. When the system detects that the gas concentration exceeds the preset threshold, and the difference between the excavation speed and the target excavation speed is less than the set difference threshold, it indicates that there are safety hazards in the current excavation environment but the excavation efficiency is acceptable. At this time, the system automatically adjusts the power of the ventilation device according to the change in gas concentration per unit time to speed up gas discharge and ensure safety. If the gas concentration continues to rise and the excavation speed drops significantly, the system will further adjust the excavation speed, reduce the excavation intensity, and increase ventilation until the environmental parameters return to a safe range.

[0044] Specific implementation: When the gas concentration suddenly rises to 1.5% (assumed to be the concentration threshold) and the excavation speed is only slightly lower than the target speed, the system calculates the increase in gas concentration per unit time and adjusts the power of the ventilation device to the maximum accordingly, while keeping the excavation speed unchanged to quickly reduce the gas concentration.

[0045] If the gas concentration continues to rise to 2% and the excavation speed slows down significantly, the system will automatically reduce the excavation speed by 20% and further optimize the operating parameters of the ventilation device to ensure that the excavation operation is carried out in a safe environment.

[0046] Example 2: Application of intelligent control system in underground tunnel excavation In a complex underground tunnel excavation project, the intelligent control system of the present invention also plays an important role. The system not only monitors the excavation speed, but also pays close attention to key environmental parameters such as groundwater level and air quality (such as oxygen content and harmful gas concentration).

[0047] Dynamic adjustment of excavation strategy: Initial strategy formulation: The cloud data server generates an initial excavation strategy including excavation speed, equipment power control and drainage device operating parameters based on the tunnel design drawings, geological conditions and the performance of the excavation equipment.

[0048] Strategy revision and optimization: Abnormal environmental parameter handling: During the excavation process, if the system detects an abnormal rise in the groundwater level, threatening the safety of excavation, and the excavation speed is not much different from the target speed, the system will immediately start the drainage device and adjust its drainage capacity according to the water level rise rate to ensure that the excavation area remains dry.
