[0017] The hierarchical storage adjustment module is used to receive the storage control instructions sent by the intelligent coupling control center module, and store the mine water according to the purpose of the mine water, after the mine water is stored as industrial water or irrigation water, the mine water is adjusted to generate adjusted industrial water or irrigation water, and the adjusted industrial water or irrigation water is transported to the target-oriented purification module through the pipeline.

[0018] In this embodiment, the purpose of designing the hierarchical storage adjustment module is to store the mine water according to the purpose of water use (use), and to monitor the water level and water quality in real time, so as to provide a stable water source for the subsequent purification module, and also to provide a buffer center for the system water quality and quantity; wherein the structure and connection relationship of the hierarchical storage adjustment module is as shown in Figure 3 As shown, including an industrial water adjustment tank module and an irrigation water adjustment tank module, and the industrial water adjustment tank module and the irrigation water adjustment tank module are both provided with a liquid level sensor, a water quality monitoring sensor, and a stirring device.

[0019] The industrial water conditioning pool module is used for receiving water flow distribution direction, stirring start-stop and sewage instruction sent by the intelligent coupling regulation and control center module, receiving and storing mine water removing large impurities, using a liquid level sensor to monitor mine water level in real time, using a water quality monitoring sensor to monitor suspended solids concentration and pH value in mine water in real time, setting periodic sewage, discharging sludge accumulated at the bottom of the pool, finally generating conditioned industrial standby water, and delivering the conditioned industrial standby water to the target guided purification module through a pipeline, and transmitting the storage state data of the conditioned industrial standby water to the intelligent coupling regulation and control center module; wherein the storage state data of the conditioned industrial standby water includes water level, suspended solids concentration and pH value.

[0020] Specifically, the specific process of using the liquid level sensor to monitor the mine water level in real time is as follows: If the mine water level is lower than the preset low water level threshold, a water replenishment request instruction is sent to the intelligent coupling regulation and control center module, otherwise, if the standby mine water level is higher than the preset high water level threshold, a water level warning instruction is sent to the intelligent coupling regulation and control center module, and the mine water delivery is stopped, otherwise, no processing is performed.

[0021] Specifically, the specific process of using the water quality monitoring sensor to monitor the suspended solids concentration in the standby mine water in real time is as follows: According to the suspended solids concentration, it is determined whether the suspended solids are settled, if yes, the stirring device is started for stirring, otherwise, no processing is performed.

[0022] In this embodiment, the industrial water conditioning pool module uses a liquid level sensor to monitor the mine water level in real time, and a low water level and a high water level are arranged in the industrial water conditioning pool of the industrial water conditioning pool module. When the stored mine water is lower than the low water level, a water replenishment request can be sent to the regulation and control center, and when the stored mine water is higher than the high water level, a water level warning instruction is sent to the regulation and control center to stop delivering mine water. In other cases, according to the requirements of subsequent modules, appropriate adjustments are made. Secondly, the module is also provided with a water quality monitoring sensor for monitoring suspended solids concentration, pH value, etc. The purpose is that when the suspended solids settle obviously, the pipeline will be blocked, therefore, a pneumatic stirring device is used for stirring. In addition, the module is also provided with a sewage valve, which is opened according to the instruction when the sludge is accumulated at the bottom of the pool, so as to realize sludge sewage. Synchronously, the module also needs to record the storage state data of the finally conditioned industrial standby water, such as water level, suspended solids concentration and pH value, and feed it back to the regulation and control center for subsequent purification treatment.

[0023] The irrigation water conditioning pool module is used for receiving the water flow distribution direction, stirring start-stop and sewage discharge instructions sent by the intelligent coupling regulation and control center module, receiving and storing the mine water from which large impurities are removed, using a liquid level sensor to monitor the mine water level in real time, using a water quality monitoring sensor to monitor the suspended matter concentration, COD initial value and microorganism quantity in the mine water in real time, setting periodic sewage discharge, discharging the sludge accumulated at the bottom of the pool, finally generating the irrigation standby water, and delivering the irrigation standby water to the target-oriented purification module through a pipeline, and transmitting the storage state data of the irrigation standby water to the intelligent coupling regulation and control center module; wherein the storage state data of the irrigation standby water includes the water level, COD initial value (chemical oxygen demand) and microorganism quantity.

[0024] Specifically, the specific process of monitoring the mine water level in real time by using the liquid level sensor is as follows: It is judged whether the mine water level is lower than the preset low water level threshold, if yes, a water replenishment request instruction is sent to the intelligent coupling regulation and control center module, otherwise, it is judged whether the standby mine water level is higher than the preset high water level threshold, if yes, a water level warning instruction is sent to the intelligent coupling regulation and control center module, and the mine water delivery is stopped, otherwise, no processing is performed.

[0025] Specifically, the specific process of monitoring the suspended matter concentration in the standby mine water in real time by using the water quality monitoring sensor is as follows: According to the suspended matter concentration, it is judged whether the suspended matter is settled, if yes, the stirring device is started to stir, otherwise, no processing is performed.

[0026] In this embodiment, the irrigation water conditioning pool module is provided with a liquid level sensor, a water quality monitoring sensor and a stirring device, and the irrigation water conditioning pool is also provided with a low water level and a high water level to prevent water shortage or excessive storage of mine water, which exceeds the capacity of the conditioning pool and thus overflows; secondly, the water quality monitoring sensor provided in the module is used to monitor the suspended matter concentration, COD initial value and microorganism quantity, because the water quality required by industrial water and agricultural irrigation water is different, the water quality parameters monitored by the two are different; and in actual application, the monitored water quality parameters can be adjusted according to the purpose of water use; secondly, the module also needs to record the storage state data of the final adjusted irrigation standby water, such as the water level, COD initial value and microorganism quantity, and feed it back to the regulation and control center for subsequent purification treatment.

[0027] The target-oriented purification module is used for receiving the purification regulation and control instructions sent by the intelligent coupling regulation and control center module, performing targeted purification treatment on the adjusted industrial standby water or irrigation standby water, generating the industrial standby water or irrigation standby water that meets the standard, and delivering it to the multi-scene utilization module through a pipeline.

[0028] In this embodiment, the purpose of designing the target-oriented purification module is to purify mine water according to the differentiated water quality requirements of industrial production and agricultural irrigation, so as to ensure that the effluent meets the standards, which is the core of the system water purification; the structure and connection relationship of the target-oriented purification module is as shown in Figure 4 , which includes an industrial water purification submodule and an irrigation water purification submodule.

[0029] The industrial water purification submodule is used to receive the reagent dosing instructions, backwashing instructions and hardness adjustment instructions sent by the intelligent coupled regulation center module, store the adjusted industrial water to be used in the industrial water purification tank, generate the industrial water to be used that meets the standards through coagulation sedimentation, quartz sand filtration and hardness adjustment operation, and deliver the industrial water to be used that meets the standards to the multi-scene utilization module through a pipeline, and at the same time, transmit the purification state data of the industrial water to be used that meets the standards to the intelligent coupled regulation center module; wherein the purification state data of the industrial water to be used that meets the standards includes effluent hardness, filtration pressure difference and reagent consumption.

[0030] In this embodiment, the industrial water purification submodule is designed to purify the adjusted industrial water to be used, including coagulation sedimentation, quartz sand filtration and hardness adjustment, specifically as follows: 1) According to the reagent dosing instructions sent by the regulation center, coagulation sedimentation is performed on the adjusted industrial water to be used, that is, polyaluminum chloride (PAC) is dosed according to the instructions, and the mixture is quickly stirred in the industrial water purification tank to form flocs, and then the flocs are settled to remove the suspended solids in the mine water, that is, when the suspended solids are settled, the lower part is the sediment, and the upper part is the clean mine water; 2) The mine water from which the suspended solids are removed is filtered through quartz sand, that is, the settled mine water is input into the filter tank, the filter material particle size and filtration speed are set, and according to the instructions, the filter tank is started for backwashing, so as to generate filtered mine water; 3) The filtered mine water is subjected to hardness adjustment, that is, a scale inhibitor is dosed according to the instructions (in actual industrial application, the scale inhibitor can be selected according to the purpose of water use), so as to control the total hardness, and finally generate the industrial water to be used that meets the standards, and at the same time, the purification state data of the industrial water to be used that meets the standards, such as effluent hardness, filtration pressure difference and reagent consumption, are also needed to be sent to the regulation center.

[0031] The irrigation water purification submodule is used to receive the grid cleaning instructions and disinfection intensity instructions sent by the intelligent coupled regulation center module, store the adjusted irrigation water to be used in the irrigation water purification tank, generate the irrigation water to be used that meets the standards through fine grid filtration, biological contact oxidation and ultraviolet disinfection, and deliver the irrigation water to be used that meets the standards to the multi-scene utilization module through a pipeline, and at the same time, transmit the purification state data of the irrigation water to be used that meets the standards to the intelligent coupled regulation center module; wherein the purification state data of the irrigation water to be used that meets the standards includes effluent COD and microbial quantity.

[0032] In this embodiment, the irrigation water purification submodule is designed to perform targeted purification of the regulated irrigation water, including fine grid filtration, biological contact oxidation, and ultraviolet disinfection, specifically: 1) Fine screen filtration, which involves passing mine water through an automatic cleaning screen with a small aperture to remove residual small particulate impurities; 2) Biological contact oxidation, which involves feeding mine water with small impurities removed into a biological tank for microbial degradation of organic matter to control COD to less than or equal to 60 mg / L; 3) Ultraviolet disinfection: After the mine water has been degraded by microorganisms, the intensity of ultraviolet light is adjusted according to instructions to eliminate bacteria that are harmful to the biological areas of agricultural irrigation, such as E. coli, to ensure irrigation safety. Finally, qualified irrigation water is generated. At the same time, the purification status data of the qualified irrigation water, such as effluent COD and microbial count, are recorded and sent to the control center.

[0033] The multi-scenario utilization module is used to receive supply control instructions sent by the intelligent coupling control center module, and deliver qualified industrial or irrigation water to the corresponding water use scenario for industrial or agricultural water supply utilization.

[0034] In this embodiment, the purpose of designing the multi-scenario utilization module is to accurately deliver qualified mine water to the corresponding water terminals, ensure on-demand supply through real-time feedback of water usage status, and serve as the system's water resource output terminal; the structure and connection relationship of the multi-scenario utilization module are as follows: Figure 5 As shown, it includes an industrial production water unit module and an agricultural irrigation water unit module. The industrial production water unit module is equipped with a pressure sensor and a flow sensor, while the agricultural irrigation water unit module is equipped with a flow sensor and a soil moisture sensor.

[0035] The industrial production water unit module receives frequency and pressure regulation commands from the variable frequency water supply pump sent by the intelligent coupling control center module. It then uses the variable frequency water supply pump to deliver industrial water to the industrial water supply scenario. The module also uses a pressure sensor to monitor the industrial pipeline pressure in real time and a flow sensor to monitor the real-time water consumption. Simultaneously, it transmits the water status data of the industrial production water unit module to the intelligent coupling control center module. The water status data of the industrial production water unit module includes the industrial pipeline pressure and the real-time water consumption.

[0036] In this embodiment, the industrial water supply unit module adjusts the frequency of the frequency conversion water supply pump according to the instruction, and then delivers water to the industrial water scene, such as the underground dust spray system and the equipment cooling system, so as to realize the water supply of the industrial scene, and at the same time, the pressure sensor is used to realize the pressure monitoring of the industrial scene water pipe network, so as to ensure the normal operation of the water terminal. For example, when the water is delivered to the underground dust spray system, if the pipe network pressure is too low, the water mist particles sprayed by the spray system will be too large and the range will be too close, which cannot effectively capture and settle dust, resulting in a significant decrease in dust prevention effect and increasing the safety risk of underground dust explosion. If the pressure is too high, the spray nozzle may be damaged, causing the nozzle to be blocked or broken, which not only affects the dust prevention effect, but also increases the equipment maintenance cost and time. Secondly, the flow sensor is used to monitor the real-time water consumption. At the same time, the water state data such as pipe network pressure and real-time water consumption are recorded and fed back to the control center for real-time adjustment of water supply.

[0037] The agricultural irrigation water unit module is used to receive the flow valve opening degree instruction and the irrigation timing instruction sent by the intelligent coupling control center module, adjust the opening degree of the main pipe network flow valve, deliver the irrigation water to the agricultural water scene, and automatically start and stop the branch pipe network according to the irrigation timing to supply water to the agricultural water scene. The flow sensor is used to record the regional irrigation amount of the agricultural water supply scene, and the soil moisture sensor is used to monitor the regional soil moisture of the agricultural water supply scene to determine whether the irrigation is sufficient. At the same time, the water state data of the agricultural irrigation water unit module is transmitted to the intelligent coupling control center module. The water state of the agricultural irrigation water unit module includes irrigation flow and soil moisture.

[0038] In this embodiment, the agricultural irrigation water unit module adjusts the opening degree of the main pipe network flow valve according to the instruction (such as 50% corresponding to the flow of 80m³ / h), and the branch pipe network automatically starts and stops according to the irrigation timing (such as 2 hours in the morning and evening) to realize the water supply of the agricultural water scene. At the same time, the flow sensor is used to record the regional irrigation amount, the soil moisture sensor is used to assist in determining whether the irrigation is sufficient, and the water state data such as irrigation flow and soil moisture are fed back to the control center.

[0039] The intelligent coupling control center module is used to receive the monitoring state data of all modules, set the initial system control instruction, calculate the water resource utilization rate and system energy consumption, set the constraint conditions for storage and operation, establish the double objective function of maximizing water resource utilization rate and minimizing system energy consumption, use the multi-objective particle swarm optimization method to iteratively solve, and generate the optimal control instruction to realize the hierarchical storage, adjustment and multi-scene water supply of the mine water resource comprehensive utilization system.

[0040] In this embodiment, the purpose of designing the intelligent coupling control center module is to receive monitoring status data from all modules and generate optimal control commands for each module using a multi-objective particle swarm optimization method, thereby achieving system synergistic coupling and serving as the decision-making core for multiple objectives. The inputs to the intelligent coupling control center module include: 1) liquid level (water level) data (industrial / irrigation regulating tank water level) and basic water quality data (suspended solids concentration, pH value, etc.) from the hierarchical storage and regulation module; 2) purification parameter data (such as coagulant dosage, filtration pressure difference, disinfection intensity, etc.) and effluent water quality data (industrial water hardness, irrigation water COD / E. coli, etc.) from the target-oriented purification module; and 3) real-time water usage data (such as industrial / irrigation water consumption, water terminal pressure, etc.) from the multi-scenario utilization module. ;4) Preset multi-objective constraints (storage constraints, equipment operation constraints); its output is: 1) Sending acquisition control commands (such as submersible pump start / stop / frequency) to the multi-source acquisition module; 2) Sending storage control commands (such as water flow distribution direction, stirring device start / stop, pool sewage discharge) to the hierarchical storage control module; 3) Sending purification control commands (such as chemical dosage, backwashing timing, disinfection intensity) to the target-oriented purification module; 4) Sending supply control commands (such as variable frequency pump frequency, flow valve opening) to the multi-scenario utilization module; Secondly, the intelligent coupling control center module can also output system status data (such as the operating parameters of each module, water quality compliance status) to the human-machine interface for real-time display and early warning; In addition, the specific process of generating the optimal control command using the multi-objective particle swarm optimization method is as follows: First, based on the monitoring status data of all modules, the initial system control command is set as follows: , , , They represent the 1st, 2nd, and 3rd respectively. One control command.

[0041] In this embodiment, control commands ~ This is equivalent to all the commands in the previous modules, such as submersible pump start / stop and submersible pump frequency commands.

[0042] Secondly, based on system control commands, the water resource utilization rate and system energy consumption are calculated, namely:

[0043]

[0044] in, This indicates the water resource utilization rate under system control commands. This indicates the total number of water usage scenarios, including industrial water supply scenarios. Indicates the first under system control command The actual water supply for each water use scenario This indicates the usable volume of mine water, representing the total amount of mine water that can be used for industrial production and agricultural irrigation. This indicates the system energy consumption under system control commands. This indicates the total number of power supply devices, which are the devices that provide energy support to all the above modules, such as submersible pumps. Indicates the first Taiwan power supply equipment under control commands The power below, Indicates the first Operating time of the power supply equipment This represents the total number of sub-modules for pretreatment, conditioning, and purification of mine water, i.e., the total number of water treatment units. This refers to the water treatment unit under system control commands. The energy consumption refers to the energy-consuming module among all the modules mentioned above, such as the water pretreatment submodule.

[0045] In this embodiment, by calculating water resource utilization rate and system energy consumption, a dual objective of maximizing water resources and minimizing system energy consumption is established in subsequent steps. This ensures efficient utilization of mine water resources while reducing system operating costs. Furthermore, by using particle swarm optimization to iteratively search for the Pareto optimal solution between the two objectives, the Pareto optimal solution between the two objectives is found. This avoids the disadvantages caused by optimizing a single objective, ensuring that the system does not excessively restrict water supply in pursuit of extreme energy conservation, nor does it significantly increase energy consumption in order to blindly improve utilization rate.

[0046] Then, constraints are established, including storage constraints and device operation constraints, i.e.;

[0047]

[0048] in, Indicates storage constraints, , These represent the upper and lower limits of the mine water level in the water storage tanks (referring to the regulating tank, purification tank, etc. in the above modules), which are the low and high water levels set by each of the above modules. This indicates the actual water level of the mine water in the storage tank. Indicates equipment operating constraints. , Indicates the first The effective range of a control command, such as the frequency command range for a submersible pump being 15Hz~50Hz. Indicates the first One control command.

[0049] Finally, under storage and equipment operation constraints, with the objectives of maximizing water resource utilization and minimizing system energy consumption, a multi-objective particle swarm optimization method is used for iterative solution to generate the optimal control command, specifically: Each particle in the particle swarm corresponds to a set of control commands, including the frequency of each power supply device, the valve opening degree, and the amount of mine water regulated in the water storage tank.

[0050] In this embodiment, each particle corresponds to a set of control commands including the frequency of functional equipment, valve opening degree, and water storage tank adjustment amount, which can comprehensively cover various control parameters of the system; and in subsequent steps, through the dynamic update of particle speed and position, it can quickly respond to changes in monitoring status data such as water quantity and water quality in the mine water system, so that the system can make timely adjustments to the control strategy to adapt to different working conditions, such as changes in water demand at different times.

[0051] Update the particle velocity and position, that is:

[0052]

[0053] in, Indicates the first Particle in the next iteration speed, Indicates inertia weight, , All represent learning factors. , All represent random numbers. Indicates the first Particle in the next iteration speed, Represents particles The individual optimal solution. This represents the globally optimal solution. Indicates the first Particle in the next iteration Location, Indicates the first Particle in the next iteration The location.

[0054] In this embodiment, inertia weight, learning factor, and random number are introduced into the particle swarm optimization method, so that the particle swarm optimization method can explore a wide range of possible control schemes during the iteration process, so as to accurately converge to the vicinity of the optimal solution. Compared with traditional optimization methods, it can find the optimal control command that satisfies the constraints more efficiently, reducing the cost of manual debugging and trial and error.

[0055] Based on the updated particle velocity and position, it is judged whether the maximum iteration state is reached. If yes, the Pareto optimal solution maximizing water resource utilization and minimizing system energy consumption is screened, and the real-time control instruction is generated by matching the current monitoring state data from the optimal solution, otherwise, the iteration optimization is continued.
