It can be understood that the above-mentioned scheme can also be used to solve engineering management problems.

[0036] According to this specific embodiment, the gridded landfill tracing module 101 is used to divide the landfill area into a plurality of grid units, and record the fly ash information landfilled in each grid unit, and query and trace the fly ash information;

[0037] The stacking optimization module 103 is used to stack and landfill the fly ash solidified material through stacking equipment, and to monitor and schedule the stacking process in real time.

[0038] The gap processing module 102 is used to compact the fly ash solidified material to be landfilled by means of a compacting machine, fill materials in the gaps of the fly ash solidified material, and monitor and record the gaps in the landfill area in real time.

[0039] The gridded landfill traceability module 101 manages the landfill process in a refined manner by dividing areas and establishing information management, so as to improve the traceability and management efficiency of the landfill process. The stacking optimization module 103 stacks the fly ash solids as landfill units.

At the same time, the stacking optimization module 103 should pay attention to maintaining the tightness of the landfilled fly ash solids during the stacking process to reduce the generation of gaps.

[0040] The information recording unit 105 is connected to the grid division unit 104, and the tracing query unit 106 is connected to the information recording unit 105;

[0041] The grid division unit 104 is used to set and divide a plurality of grid units in the landfill area, each grid unit having a clear number or identification;

[0042] The information recording unit 105 is used to record the type, quantity, source, landfill time, and processing information of the fly ash solidified material landfilled in each grid unit, and establish a database for management;

[0043] The traceability query unit 106 is used to query and trace the fly ash solidification information according to conditions.

[0045] Secondly, the compaction unit 107 is composed of a compaction machine and is used to compact the fly ash solidified material for landfill;

[0046] The filling unit 108 is used to fill materials in the gaps between the fly ash solidified objects.

Among them, the filling device has the function of adjusting the filling amount to ensure the filling effect. The gap detection unit 109 is equipped with a gap detection sensor or camera to monitor and record the gaps in the landfill area in real time, so as to promptly discover and deal with gap problems.

[0049] At the same time, the intelligent scheduling unit 111 is connected to the automated stacking unit 110;

[0050] The automated stacking unit 110 is composed of an automated stacking robot or a mechanical arm device, and is used for stacking fly ash solidified materials;

[0051] The intelligent scheduling unit 111 is used to monitor the stacking process in real time and schedule the automatic stacking unit 110 according to the actual situation and needs of the landfill.

[0052] The automatic stacking unit 110 introduces equipment such as automatic stacking robots or mechanical arms to achieve fast and accurate stacking of fly ash solidified materials. Among them, the automatic stacking equipment has the functions of identifying the position of solidified materials, adjusting the stacking height and angle, etc., to improve the stacking efficiency and stability. Specifically, these devices integrate high-precision sensors, such as photoelectric sensors, distance sensors, etc., and the automatic stacking equipment can accurately identify the specific coordinates of fly ash solidified materials on the conveyor belt, stacking area or other storage locations, and provide accurate guidance for subsequent stacking operations. According to the preset stacking scheme or the scheduling instructions received in real time, the automatic stacking equipment can automatically adjust its working height and angle to ensure that the fly ash solidified materials can be stacked according to the predetermined layers and sequence. This function is realized by the lifting mechanism and rotating mechanism of the equipment to ensure the accuracy and stability of the stacking. The automatic stacking robot or mechanical arm equipped with special clamps, such as suction cups, clamps, etc., can accurately grasp the fly ash solidified materials and place them according to the planned path and position. In this process, the equipment achieves fine adjustment of the grasping force, speed and position by accurately controlling the movement of each axis. The implementation principle of the automatic stacking unit 110 is mainly based on the combination of mechanical motion and control system. Specifically, it includes the following aspects: Sensor technology: By integrating multiple sensors, the environmental changes in the stacking area and the location information of the fly ash solidified material are sensed in real time to provide accurate data support for the equipment. Motion control technology: Using power devices such as motors and servo drives to drive the joints and actuators of the stacking robot or mechanical arm to move precisely. Through programming and algorithm optimization, the precise control of the motion trajectory and speed of the equipment is achieved. Visual recognition and positioning technology: Some high-end equipment is also equipped with a visual system, which captures images through a camera and processes and analyzes them to achieve accurate recognition and positioning of fly ash solidified materials. Automated control system: Comprehensively process and analyze information such as sensor data, motion control instructions and visual recognition results, and realize real-time monitoring and scheduling of the entire stacking process through an automated control system. The intelligent scheduling unit 111 establishes an intelligent scheduling platform to monitor and schedule the stacking process in real time according to the actual situation and needs of the landfill. The intelligent scheduling platform has the functions of optimizing the stacking path, improving stacking efficiency, reducing errors and safety hazards. Specifically, according to the actual situation and needs of the landfill, the intelligent scheduling platform can calculate the optimal stacking path and sequence, reduce the ineffective movement and waiting time during the stacking process, and improve the stacking efficiency. By real-time monitoring of the operating status and stacking progress of the stacking equipment, the intelligent scheduling platform can adjust the scheduling plan in time to ensure the efficient stacking operation. By integrating a variety of sensors and monitoring equipment, the intelligent scheduling platform can monitor the environmental changes and operating status of the stacking area and the equipment in real time, detect and handle abnormal situations in time, and reduce the occurrence of errors and safety hazards. The implementation principle of the intelligent scheduling unit 111 is mainly based on the combination of intelligent algorithms and automatic control technology.Specifically, it includes the following aspects: Intelligent algorithm: Use advanced intelligent algorithms, such as genetic algorithm, particle swarm algorithm, etc., to optimize the calculation of stacking path and sequence. These algorithms can comprehensively consider multiple factors (such as stacking efficiency, safety, energy consumption, etc.) to obtain the optimal scheduling plan. Automatic control technology: Convert the calculation results of the intelligent algorithm into specific control instructions, and realize precise control of the stacking equipment through the automatic control system. In this process, the control system needs to receive sensor data and monitoring information in real time, and make dynamic adjustments as needed. Data communication technology: Through industrial Ethernet, fieldbus and other communication methods, data exchange and information sharing between the intelligent scheduling platform and the stacking equipment are realized. This helps to realize real-time monitoring and scheduling management of the entire stacking process.

[0053] In addition, the comprehensive management module 112 is respectively connected to the grid landfill tracing module 101, the gap processing module 102 and the stacking optimization module 103;

[0054] The comprehensive management module 112 is used to monitor the operating status of each module and the environmental parameters of the landfill process, and is equipped with safety protection facilities.

[0055] The integrated management module 112 serves as the center of the entire system, monitoring and controlling the operating status of each module, as well as key parameters such as temperature, humidity, and pressure during the landfill process, to ensure the safety and stability of the landfill process. It also monitors and records environmental indicators of the landfill in real time, provides data support for the control system, and is equipped with safety protection facilities and emergency response systems including explosion-proof, fire-proof, and anti-toxic to ensure the safety of equipment and personnel. These facilities are closely connected with other parts of the system to form a complete safety protection network.

[0056] A fly ash solidified material stacking landfill system of the present embodiment is used. The landfill area is divided into fine grid units through the grid landfill traceability module 101, and the fly ash information in each grid is recorded in detail, including key data such as type, quantity, and landfill time. This management method greatly improves the transparency and traceability of landfill operations, facilitates subsequent environmental monitoring, risk assessment, and emergency response when necessary, and effectively ensures the environmental safety of the landfill site. The stacking optimization module 103 uses advanced intelligent algorithms and stacking equipment to monitor and intelligently schedule the stacking process of fly ash solidified materials in real time. By optimizing the stacking path, reducing invalid movement and waiting time, the efficiency of stacking operations is significantly improved, and the manpower and material costs are reduced. At the same time, intelligent operation also reduces human errors and improves the safety and accuracy of operations. The gap processing module 102 compacts the landfilled fly ash solidified materials through compaction machinery, effectively reducing the gaps inside the landfill body and improving the overall stability of the landfill body. In addition, filling the gaps with appropriate materials, such as artificial sodium bentonite, soil, sand, municipal sludge, etc., further enhances the sealing and environmental isolation effect of the landfill, prevents the leakage and diffusion of pollutants, and protects groundwater and the surrounding ecological environment. By using environmentally friendly materials such as artificial sodium bentonite to fill the gaps, the exploitation and consumption of natural resources are reduced. At the same time, the reuse of waste such as municipal sludge also reflects the concept of resource recycling and waste reduction, which helps to achieve sustainable development. The modules are closely connected and support each other to form an efficient and coordinated landfill system. From the reception, solidification, stacking to gap processing of fly ash, every link has been carefully designed and optimized to ensure the smoothness and efficiency of the entire landfill process. This systematic management method not only improves the efficiency and quality of landfill operations, but also reduces operating costs and maintenance difficulties.

[0057] When problems occur in the system, this close connection and mutual support ensure that the problems are quickly located and effective solutions are taken.

[0058] Specifically, the grid landfill traceability module 101 provides powerful data support and information query capabilities for the entire system. Once a problem is found, such as leachate leakage, abnormal gas emission or decreased stability of the landfill, the system can immediately query the fly ash information in the relevant grid unit through the traceability query unit 106, including landfill time, type, quantity and treatment measures. This information provides an important basis for the rapid location and cause analysis of the problem. Secondly, the collaborative work between the stacking optimization module 103 and the gap processing module 102 can respond to problems quickly. If it is monitored that there is a stability problem in the landfill or a pollution risk caused by improper gap processing, the stacking optimization module 103 can adjust the stacking path and strategy to avoid further aggravation of the problem; and the gap processing module 102 can immediately start the filling device to fill and seal the found gaps to prevent further spread of pollutants. In addition, the comprehensive management module 112 can monitor various environmental indicators and landfill status of the landfill in real time. The modules adopt a modular design and can be flexibly configured and expanded according to actual needs. When faced with new challenges or new problems need to be solved, the system can adapt to changes by adding new modules or optimizing existing modules to ensure that landfill operations always remain efficient and safe. The landfill system in which each module is closely connected and mutually supportive not only improves the efficiency and quality of landfill operations, but also enhances the stability and safety of the system. When problems arise, the system can quickly locate and take measures to effectively prevent the spread of pollutants and environmental damage, making important contributions to environmental protection and sustainable development.

[0059] The second embodiment of the present application is:

[0060] Based on the first embodiment, please refer to Figure 5 ,in, Figure 5 2 is a principle block diagram of the integrated management module 112 of the second embodiment of the present invention. The integrated management module 112 of this embodiment includes a monitoring unit 201 , a detection unit 202 and a protection unit 203 .

[0061] According to this specific implementation, the detection unit 202 is connected to the monitoring unit 201, and the protection unit 203 is connected to the detection unit 202;

[0062] The monitoring unit 201 is used to monitor the operating status of each module and the temperature, humidity and pressure parameters of the landfill process, as well as to monitor and record the environmental indicators of the landfill in real time, and upload the monitoring data to the detection unit 202;

[0063] The detection unit 202 is used to display the monitoring data and set a threshold. If the monitoring data exceeds the threshold, an early warning message is issued;

[0064] The protection unit 203 is used to be equipped with explosion-proof, fire-proof and poison-proof safety protection facilities.

[0065] Using a fly ash solidified material stacking landfill system of this embodiment, the monitoring unit 201 monitors the working status of each module in real time, such as the operating efficiency of the stacking equipment, the filling status of the gap processing machine, etc., through the sensors and monitoring equipment integrated in each module. Temperature sensors, humidity sensors, pressure sensors, etc. are set in the landfill to monitor the temperature, humidity and pressure changes of the landfill body, as well as the air quality and groundwater conditions of the surrounding environment in real time. The monitored data is transmitted to the detection unit 202 in real time, and stored and recorded for subsequent analysis and tracing. The detection unit 202 intuitively displays the real-time values ​​and change trends of various monitoring data in the form of a graphical interface or a dashboard. According to the design standards and safety requirements of the landfill, reasonable thresholds are set for various monitoring parameters. These thresholds are usually derived based on scientific research and practical experience, and can reflect the safety status and potential risks of the landfill. When the monitoring data exceeds the threshold, the detection unit 202 will automatically trigger the early warning mechanism and send early warning information to relevant personnel through various means such as sound, light, text message, and email. At the same time, the early warning information can also be pushed to the intelligent scheduling platform so that timely measures can be taken for processing. The protection unit 203 is equipped with explosion-proof electrical equipment, explosion-proof lamps, etc. in the landfill to reduce the risk of explosion caused by electrical equipment failure. At the same time, the equipment is regularly inspected and maintained to ensure that it is in good condition. Firefighting equipment and facilities, such as fire extinguishers, fire hydrants, sprinkler systems, etc., are equipped to quickly put out fires when they occur. In addition, detailed emergency plans are formulated and fire drills are organized regularly. Since landfills may produce toxic and harmful gases (such as methane, hydrogen sulfide, etc.), it is necessary to set up gas monitoring systems and ventilation equipment to monitor and remove harmful gases in real time. At the same time, staff should wear personal protective equipment such as protective masks and respirators to reduce the harm of toxic gases to the human body. Through real-time monitoring, early warning and protection measures, the safety risks of landfills can be effectively reduced, and the safety, efficiency and environmental protection of landfill operations can be guaranteed.
