DETAILED DESCRIPTION

[0011] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0012] In the relevant technology, the reliability of the power supply system is crucial in mining operations, especially in remote mining areas far away from the mains power grid. Traditional power supply methods usually rely on generator sets or batteries, but these methods face many challenges in practical applications. For example, diesel generator sets require regular maintenance and fuel transportation costs are high, while battery charging and discharging management requires precise control, and charging efficiency is limited by the stability of the power supply.

[0013] In the mining environment, there is a compressed air power source system underground in the coal mine, which can provide energy for pneumatic tools. Therefore, using a pneumatic motor to drive a generator to power the equipment has become a viable alternative. This method can not only effectively utilize the existing resources of the mine, but also reduce the maintenance cost of traditional power generation equipment. However, due to the instability of the air supply, the output power of the pneumatic motor may fluctuate, which poses a challenge to the subsequent power supply and the overall stability of the system. Therefore, how to effectively utilize the power generation capacity of the pneumatic motor while ensuring the stable power supply of the rechargeable battery and the load is a technical problem that needs to be solved.

[0014] like Figure 1 As shown, this embodiment provides a power supply control method, which can be executed by a controller, and the controller can be configured in a power supply system, which may include: Step S102: Determine the operating parameter data at the current moment; wherein the operating parameter data at least includes: the power generation power of the power generation device, the load power consumption and the energy storage battery charging power; wherein the power generation device is powered by a pneumatic motor.

[0015] In this embodiment, the action of determination may be determined actively or passively by condition triggering. For example, active determination may be that the controller actively obtains the current operating parameter data regularly according to a preset time interval. The period may be one minute or two minutes, etc. The specific number of minutes is not limited in this embodiment. Passive triggering may be that when a specific condition change is detected (such as a sudden increase in load or a fluctuation in the air supply of the pneumatic motor), the acquisition process of the operating parameter data is automatically triggered.

[0016] In this embodiment, the operating parameter data may include the power generation of the electrical device, the power consumption of the load, and the charging power of the energy storage battery. It may also include: charging time data and power change data of the energy storage battery. In some embodiments, the operating parameter data may also include: operating status data of the pneumatic motor, air source supply status data, ambient temperature and humidity data, and load status data, etc. It is understandable that the operating status data of the pneumatic motor may further include the speed of the pneumatic motor, the input air pressure, the air flow rate, etc., which can help determine the working efficiency and current load conditions of the pneumatic motor. The air source supply status data may further include the pressure of the air source, the gas flow rate, the air source temperature, etc., which are helpful to monitor the stability of the air source and the air supply condition of the pneumatic motor. The load status data may further include the real-time power demand of the load, the working mode of the load (such as standby, operation, peak, etc.), which are helpful to dynamically adjust the power supply strategy to adapt to different load requirements.

[0017] In this embodiment, the controller can uniformly extract the above-mentioned operating parameter data from a database, which collects and stores the operating parameter data from the corresponding equipment or devices in advance. It is also possible that the controller extracts the operating parameter data from the corresponding equipment or devices respectively. For example, for the power generation of a power generation device, the power generation power can be measured by a power sensor or an electric meter connected to the output end of the power generation device. For the load power consumption, the actual power consumption of the load device can be monitored, for example, using a preset power meter or energy meter to measure the power consumption of the current load. For the charging power of the energy storage battery, the battery charging power can be monitored in real time through a battery management system (BMS) or a power sensor installed on the charging line.

[0018] In this embodiment, the power generation device is powered by a pneumatic motor, which is driven by an air source. The air source can be provided by a compressed air power source system in an underground coal mine working environment. In other words, the air source can be compressed air. It is also understandable that in an underground coal mine environment, the temperature and humidity vary greatly, and the dust concentration is also high, and traditional power equipment is easily affected by these factors. However, due to the relatively simple structure, good sealing and strong durability of the pneumatic motor and the power generation device, they can operate stably for a long time in such a harsh environment.

[0019] In this embodiment, the pneumatic motor may be a vane pneumatic motor, a piston pneumatic motor, a turbine pneumatic motor, or the like.

[0020] In this embodiment, the power generation device may be a brushless DC generator, a synchronous AC generator or an asynchronous AC generator, etc. It is understandable that if the power generation device adopts a synchronous AC generator or an asynchronous AC generator, a rectifier may also be provided, and the rectifier is used to convert the AC power generated by the power generation device into DC power so as to supply power to the energy storage battery and other DC loads.

[0021] In this embodiment, the load may be lighting equipment, communication equipment, monitoring equipment, pneumatic drilling rigs, pneumatic rock drills, pneumatic wrenches, etc.

[0022] In this embodiment, the energy storage battery can be a lithium-ion battery or a lead-acid battery, etc.

[0023] Step S104: Match the operating parameter data with a preset power supply control strategy set to determine a target power supply control strategy.

[0024] In this embodiment, the power supply control strategy set may include multiple power supply control strategies, and each power supply control strategy may also correspond to a trigger condition in the power supply control strategy set. The trigger condition is used to match the operating parameter data. When the trigger condition is matched, the corresponding power supply control strategy is hit, and the controller can execute the corresponding power supply control strategy.

[0025] In this embodiment, the structure of the power supply control strategy set may be as shown in the following table. It is understood that the trigger conditions and power supply control strategies in this embodiment are not limited to only two. The embodiment does not limit the specific number of trigger conditions and power supply control strategies.

[0026] In a possible specific implementation scheme, the power supply control strategy set may include a priority power supply strategy when power is insufficient, a load distribution strategy when power generation is in excess, and a pneumatic motor adjustment strategy when the air source fluctuates, etc.

[0027] 1. For the priority power supply strategy when power supply is insufficient, the triggering conditions can be: The power generation of the power generation device is less than the load power consumption + the minimum charging power of the energy storage battery. And the remaining power of the energy storage battery is less than 20%.

[0028] Priority power supply policies when power supply is insufficient may include: Reduce the power supply priority of non-critical loads and give priority to powering critical equipment (such as communication equipment and monitoring equipment). Suspend the charging of energy storage batteries and supply all available power to the loads.

[0029] 2. For the load distribution strategy when there is excess power generation, the triggering conditions can be: The power generation of the power generation device is greater than the load power consumption + the maximum charging power of the energy storage battery. And the remaining power of the energy storage battery is greater than 80%.

[0030] Load distribution strategies when there is excess power generation may include: Increase the power supply to all loads and use the excess power to quickly charge the energy storage battery. If the energy storage battery is full, the excess power is used to drive backup equipment or for energy recovery.

[0031] 3. For the pneumatic motor adjustment strategy when the air source fluctuates, the triggering conditions can be: The gas supply status (such as gas pressure or gas flow) fluctuates by >10% (the set stable range).

[0032] The pneumatic motor adjustment strategy when the air source fluctuates may include: Adjust the opening of the control valve to stabilize the air flow of the pneumatic motor to maintain the stable output power of the generator. If the air source fluctuates and cannot be stabilized, start the backup air source or switch to the backup generator.

[0033] Step S106: Execute the target power supply control strategy so that the power generation device can stably supply power to the load and the energy storage battery.

[0034] In this embodiment, the executed action can be represented as the controller generating corresponding control signals according to the target power supply control strategy, and sending these signals to relevant hardware components (such as pneumatic motors, control valves, power generation devices, energy storage battery management systems, etc.). The controller adjusts the operating state of the device by sending signals, including starting or stopping the device, changing the working mode of the device, adjusting the power output, etc. For example, if the target power supply control strategy requires reducing the power output of the pneumatic motor, the controller will send a signal to the control valve to adjust the valve opening to reduce the gas flow entering the pneumatic motor.

[0035] In this embodiment, the controller will continuously monitor key parameters in the system (such as power generation power, load power, energy storage battery status, etc.) while executing the target power supply control strategy. If the monitored parameters do not meet expectations after executing the target power supply control strategy, the controller can adjust the target power supply control strategy to perform new control actions. For example, after reducing the power of the pneumatic motor, the controller can monitor the output power of the power generation device in real time to ensure that it reaches the expected stable level. It is understandable that during the execution process, if the operating parameters change, the controller can re-evaluate the effectiveness of the current strategy and switch to another power supply control strategy if necessary. During the execution process, the controller can also record the operating status and execution results of each device to provide data support for subsequent system optimization and maintenance.

[0036] In summary, in this embodiment, by determining the operating parameter data and matching it with the preset power supply control strategy set, the optimal power supply control strategy is determined and executed, which effectively addresses the power fluctuation problem of the pneumatic motor driven generator under different working conditions. This method can not only ensure the stable power supply of the load and energy storage battery under various power supply conditions, but also improve the overall efficiency of the system, reduce unnecessary energy waste and resource consumption, extend the service life of the equipment, and significantly improve the reliability and economy of the power supply system.

[0037] In some implementations, the step of matching the operating parameter data with a preset power supply control strategy set to determine a target power supply control strategy includes: When the power generation power of the power generation device is less than the sum of the load consumption power and the energy storage battery charging power, the corresponding operating parameter data is matched with the preset power supply control strategy set to obtain a first target control strategy; wherein, the first target control strategy at least includes: reducing the energy storage battery charging power, so that the power generation power of the power generation device is greater than or equal to the load consumption power and the energy storage battery charging power.

[0038] In this embodiment, the controller can use the current operating parameter data to compare with the trigger conditions in the power supply control strategy set to obtain the first target control strategy. The current operating parameter data is the operating parameter data in which the power generation of the power generation device is less than the sum of the load power consumption and the energy storage battery charging power.

[0039] It is understandable that after determining the first target control strategy, the controller can generate one or more control signals according to the preset power supply control strategy. The controller then sends the one or more control signals to the battery management system (BMS), instructing it to reduce the output charging current, thereby directly reducing the charging power. In some cases, the controller can also instruct to reduce the charging voltage, which can reduce the battery's absorbed power and avoid over-fast charging.

[0040] In this embodiment, by dynamically adjusting the charging power of the energy storage battery when the power generation of the power generation device is lower than the sum of the load power consumption and the charging power of the energy storage battery, the power demand of the load can be prioritized to avoid the shutdown of key equipment or system instability due to insufficient power supply. This strategy achieves the optimal configuration of limited resources through intelligent power distribution, which not only ensures the reliability of the power supply system, but also extends the service life of the energy storage battery, reduces unnecessary energy waste in the system, and improves the overall energy utilization efficiency.

[0041] In some embodiments, the pneumatic motor is driven by a gas source by providing gas power. When the power generation power of the power generation device is less than the sum of the load power consumption and the energy storage battery charging power, the first target control strategy further includes: The gas source is controlled to increase the gas supply to the pneumatic motor to increase the power supply of the power generation device, so that the increased power supply can be greater than or equal to the load consumption power and the energy storage battery charging power.

[0042] In this embodiment, the output power of the pneumatic motor is increased by dynamically adjusting the gas supply, thereby increasing the power supply capacity of the power generation device and effectively coping with the situation of insufficient power generation. When the power supply of the power generation device is lower than the sum of the load consumption power and the energy storage battery charging power, the controller can promptly increase the gas power input of the pneumatic motor so that the power generation power is quickly increased to a level that meets the system requirements, thereby ensuring the continuous power supply of key equipment, quickly responding to load changes, optimizing energy utilization, and avoiding system shutdown or instability due to insufficient power supply. At the same time, this method can also reduce the long-term operation of the pneumatic motor under low load, extend the life of the equipment, enhance the flexibility and stability of the power supply system, and ensure efficient and reliable operation of the system.

[0043] In some implementations, the step of matching the operating parameter data with a preset power supply control strategy set to determine a target power supply control strategy includes: When the power generation of the power generation device is greater than the sum of the load power consumption and the energy storage battery charging power, and the difference between the power generation of the power generation device and the sum of the load power consumption and the energy storage battery charging power meets the first threshold, the corresponding operating parameter data is matched with the preset power supply control strategy set to obtain a second target control strategy; wherein the second target control strategy includes: The charging power of the energy storage battery is increased, so that at least the difference between the power generation power of the power generation device and the sum of the load power consumption and the charging power of the energy storage battery is lower than a first threshold.

[0044] In this embodiment, the first threshold value may be a fixed value, such as a 5% or 10% power margin. That is, when the power generation of the power generation device is 5% or 10% higher than the sum of the load power consumption and the energy storage battery charging power, the second target control strategy is started. The first threshold value may be a dynamic range, for example, a percentage range that can be adjusted in real time according to load changes or energy storage battery status.

[0045] In this embodiment, the controller can generate a corresponding control signal according to the current charging power and battery status (such as battery voltage, current, temperature, etc.), instructing the charging control module to increase the charging current or voltage. The controller sends a control signal to the battery management system (BMS) to increase the charging power of the battery. After increasing the charging power, the controller can continuously monitor the output power of the power generation device and the charging status of the energy storage battery to confirm the effect of the adjustment. If the difference of the system is still higher than the first threshold, the controller can further increase the charging power until the difference drops below the first threshold.

[0046] It can be understood that at least making the difference between the power generation of the power generation device and the sum of the power consumption of the load and the charging power of the energy storage battery lower than the first threshold means that the controller increases the charging power of the energy storage battery to ensure that the difference between the power generation of the power generation device and the sum of the power consumption of the load and the charging power of the energy storage battery is reduced to a level not exceeding the first threshold, or further reduced to a range smaller than the first threshold. For example, if the state of the energy storage battery allows a higher charging power, the controller can further adjust so that the difference is significantly smaller than the first threshold to achieve better system efficiency and energy utilization.

[0047] In this embodiment, when the power generation of the power generation device is only slightly higher than the sum of the load power consumption and the charging power of the energy storage battery (that is, when the first threshold is met), the power balance of the system can be accurately adjusted by increasing the charging power of the energy storage battery. This strategy can effectively absorb excess power generation, so that the output of the power generation device is more in line with system requirements, avoiding energy waste or excessive operation of power generation equipment due to excess power. At the same time, this method not only ensures efficient use of energy by optimizing the charging efficiency of the energy storage battery, but also achieves stable operation of the power supply system without significantly adjusting other system parameters, thereby improving the response speed and reliability of the overall system and ensuring that the power supply system is always in the best state under various operating conditions.

[0048] In some implementations, the step of matching the operating parameter data with a preset power supply control strategy set to determine a target power supply control strategy includes: When the power generation of the power generation device is greater than the sum of the load power consumption and the energy storage battery charging power, and the difference between the power generation of the power generation device and the sum of the load power consumption and the energy storage battery charging power meets the second threshold, the corresponding operating parameter data is matched with the preset power supply control strategy set to obtain a third target control strategy; wherein the second threshold is higher than the third threshold, and the third target control strategy at least includes: The gas source is controlled to reduce the gas supply to the pneumatic motor to reduce the power supply of the power generating device, so as to at least make the difference between the power generated by the power generating device and the sum of the load consumption power and the charging power of the energy storage battery lower than a second threshold.

[0049] It can be understood that the third target control strategy is determined when the power generation of the power generation device is greater than the sum of the load power consumption and the energy storage battery charging power, and the difference between the power generation of the power generation device and the sum of the load power consumption and the energy storage battery charging power meets the second threshold. In addition to the above control strategy, the third target control strategy may further include the second target control strategy, that is, to increase the charging power of the energy storage battery, so as to at least make the difference between the power generation of the power generation device and the sum of the load power consumption and the energy storage battery charging power lower than the first threshold.

[0050] In other words, in this embodiment, when the power generation of the power generation device is greater than the sum of the load power consumption and the charging power of the energy storage battery, and the difference reaches or exceeds the second threshold, the system can determine the above-mentioned third target control strategy. The third target control strategy can not only include reducing the power supply of the power generation device by reducing the gas supply of the pneumatic motor so that the difference drops below the second threshold, but also further include the second target control strategy, that is, increasing the charging power of the energy storage battery, thereby further reducing the difference to at least below the first threshold. By combining the two control strategies, the system can more effectively optimize energy utilization, avoid over-powering, and ensure the stability and efficiency of the power supply system under various load conditions.

[0051] In this embodiment, when the difference between the power generation of the power generation device and the sum of the load power consumption and the charging power of the energy storage battery exceeds the second threshold, the gas supply to the pneumatic motor is reduced by controlling the gas source, thereby effectively reducing the power supply power of the power generation device, thereby avoiding energy waste or excessive operation of the equipment due to excess power. Since the second threshold is higher than the first threshold, this strategy intervenes in time when the gap between the power generation and the system demand is large, and by accurately regulating the output of the power generation device, the difference is reduced to below the second threshold, or even closer to the system demand, thereby ensuring the stability of the power supply system and energy efficiency. This method can optimize resource utilization, extend equipment life, and reduce unnecessary energy consumption while ensuring the stable operation of the system.

[0052] like Figure 2 As shown, in some embodiments, a control valve is provided between the pneumatic motor and the air source, and when the target power supply control strategy is the third target control strategy, the step of executing the target power supply control strategy so that the power generation device can stably supply power to the load and the energy storage battery includes: Step S1062: Detecting the opening state information of the control valve; wherein the opening state information is used to represent the actual opening state of the control valve.

[0053] In this embodiment, the controller may detect the opening state information of the control valve through a valve opening sensor or a valve state feedback device.

[0054] In this embodiment, the control valve may be an electric control valve, a pneumatic control valve or a solenoid valve.

[0055] Step S1064: Generate an adjustment signal based on the opening state information and the difference between the power generation of the power generation device and the sum of the load power consumption and the energy storage battery charging power.

[0056] Step S1066: Sending the regulating signal to the control valve to reduce the opening state of the control valve, thereby reducing the gas flow entering the pneumatic motor, and thereby reducing the rotation speed and output power of the pneumatic motor.

[0057] In this embodiment, by setting a control valve between the pneumatic motor and the gas source and performing precise valve control under the third target control strategy, the gas supply to the pneumatic motor can be effectively reduced, thereby reducing the output power of the power generation device. First, by detecting the opening state information of the control valve, the system can accurately grasp the actual opening of the current valve, and then generate a precise adjustment signal based on this information and the difference between the power generation power and the load demand. Subsequently, by sending an adjustment signal to the control valve to reduce the opening of the valve, the system can finely control the gas flow entering the pneumatic motor and reduce its speed and output power. This process ensures that the power generation device can respond in time when there is excess power, reduce energy waste, avoid excessive operation of equipment, and ultimately achieve stability and efficiency of the power supply system.

[0058] In some embodiments, the operating parameter data further includes: charging time data and power change data of the energy storage battery, and the method further includes: The charging efficiency of the energy storage battery is determined based on the charging time data and the power change data of the energy storage battery.

[0059] In this embodiment, the controller determines the charging efficiency by comparing the change in the amount of electricity in the energy storage battery within the preset charging time and calculating the ratio between the actual input electric energy and the amount of electricity stored in the battery. Specifically, the controller records the charging current and voltage of the battery within a certain period of time, calculates the total input electric energy in combination with the time data, and monitors the actual increase in the amount of electricity in the battery. The charging efficiency can be the amount of electricity change / input electric energy. The controller can determine the charging performance and health status of the battery by analyzing this ratio.

[0060] Determine whether the charging efficiency of the energy storage battery is abnormal.

[0061] In this embodiment, the controller determines whether the charging efficiency of the energy storage battery calculated in real time is abnormal by comparing it with the preset normal efficiency range or historical data. If the current charging efficiency is significantly lower than the normal range or significantly lower than the historical average efficiency, the controller will determine that the charging efficiency is abnormal.

[0062] If it is determined to be abnormal, an alarm command is sent to the alarm device.

[0063] In this embodiment, when the charging efficiency is judged to be abnormal, the controller can send an alarm instruction to the alarm device. The alarm device can be a variety of notification devices, including an audible and visual alarm, which is used to send sound and flash signals to remind the operator; an alarm module in a remote monitoring system, which sends alarm information to the central control room or relevant maintenance personnel through the network; or a text message / email notification system, which sends the alarm information directly to the mobile phone or email of the relevant personnel.

[0064] In this embodiment, by monitoring the charging time data and power change data of the energy storage battery, the charging efficiency is calculated and judged in real time whether it is abnormal, and the battery performance degradation or potential failure can be discovered in time. When the charging efficiency is abnormal, the system immediately sends an alarm instruction to the alarm device, prompting the operator to take necessary maintenance or adjustment measures. This method can identify problems in the battery charging process at an early stage, avoid power outages or system instability caused by battery failure, improve the overall reliability and safety of the power supply system, and at the same time extend the service life of the energy storage battery to ensure the continuous and efficient operation of the system.
