Description

Technical Field

[0001] This application relates to the field of mine anomaly handling technology, and in particular to a method, apparatus and equipment for handling abnormal conditions in mines. Background Technology

[0002] During coal mining, abnormal situations may occur in the mine. To ensure the safety of the working environment and personnel, it is necessary to detect these abnormalities so that corresponding measures can be implemented upon detection. Current technologies typically rely on video surveillance or sensors for anomaly detection. However, video surveillance requires manual monitoring, which can fail in dusty environments. Sensor data is often isolated and lacks correlation, and is prone to malfunction, leading to inaccurate data acquisition and inaccurate anomaly detection. This results in inaccurate anomaly detection, preventing the generation of appropriate strategies and ultimately failing to guarantee worker safety.

[0003] Therefore, how to provide a method that can accurately detect and handle abnormal conditions in mines is an urgent technical problem to be solved. Summary of the Invention

[0037] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with the relevant laws, regulations and standards of the relevant regions, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0038] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0039] Figure 1 This is a flowchart illustrating a method for handling abnormal conditions in a mine, provided as an embodiment of this specification. From a programming perspective, the entity executing the process can be an application server or an application client carrying the program.

[0040] like Figure 1 As shown, the method may include the following steps.

[0041] Step 102: Obtain the mine information of the mine.

[0042] The mine information includes at least mine equipment information, mine structure information, and mine environment information.

[0043] In the embodiments of this specification, mine equipment information may include hardware equipment information and equipment operating parameter information; hardware equipment information may include equipment model, equipment name, equipment shape, equipment operating status, and equipment location in the mine. The types of operating parameter information may be different or the same for different equipment. For example, the operating parameters of ventilation equipment may include information such as wind speed, ventilation rate, and current; the operating parameters of conveyor belts may include information such as conveying speed and current.

[0044] In the embodiments of this specification, the mine structure information may include underground building information, mine shape information, location areas of each mine shaft opening, restricted area information, mine geological information, and shaft opening shape information, etc. Mine environmental information may include oxygen concentration information, temperature information, humidity information, and methane concentration information within the mine, etc.

[0045] In the embodiments described in this specification, mine structure information and mine environment information can be obtained through radar, cameras, sensors, etc.; mine equipment information can be uploaded to the server by the mine equipment itself.

[0046] Step 104: Obtain user information within the mine.

[0047] The user information includes at least user location information and user physiological information.

[0048] In the embodiments described in this specification, user information can be obtained through a user terminal carried by the user. The user terminal can be a wearable smart electronic device, a mobile phone, etc. User location information can be the user's coordinates in the mine. User physiological information can be information representing the user's physiological state. User physiological information may include heart rate information, blood oxygen information, respiratory rate information, etc.

[0049] Step 106: Based on the mine information and the user information, determine whether there is any abnormality in the mine.

[0050] In the embodiments of this specification, abnormal conditions in the mine may include abnormal physical conditions of the workers in the mine; abnormal equipment conditions in the mine; abnormal environmental conditions in the mine; abnormal structural conditions in the mine, and so on.

[0051] Step 108: If there is an abnormal situation in the mine, determine the factors causing the abnormal situation.

[0052] In the embodiments of this specification, factor information may include at least one of the root cause and surface factors that cause the abnormal situation. The root cause may be the fundamental reason for the occurrence of the abnormal situation. The surface factor may be the superficial reason for the occurrence of the abnormal situation. For example, if the abnormal situation is dust accumulation, which is determined by detecting dust concentration, then the surface factor can be determined to be excessively high dust concentration; through further investigation, it is determined that the excessively high dust concentration is caused by an abnormal ventilation system, preventing dust dispersion, thus determining the root cause to be an abnormal ventilation system.

[0053] Step 110: Based on the factor information, determine the risk level corresponding to the abnormal situation.

[0054] In the embodiments of this specification, the risk level can be determined based on the severity represented by the factor information; the more severe the severity represented by the factor information, the higher the risk level; the lower the severity represented by the factor information, the lower the risk level. Severity can be determined based on the degree of harm to the user's life and health. For example, extremely high gas concentrations may pose an explosion risk, posing the highest and most severe harm to the user's life and health, and can be determined as the highest risk level. The risk level can also be based on multiple pre-defined levels of equipment based on expert experience.

[0055] Step 112: Generate an anomaly handling strategy based on the risk level.

[0056] In the embodiments of this specification, the exception handling strategy can be a strategy that the server can directly execute through a communication connection; it can also be a strategy generated to prompt the user to perform an operation; or it can be a strategy that requires cooperation between the server and the user. During the generation of the exception handling strategy, a corresponding strategy can also be generated based on factor information.

[0057] It should be understood that the order of some steps in the methods described in one or more embodiments of this specification may be interchanged according to actual needs, or some steps may be omitted or deleted.

[0058] Figure 1 The method described above acquires mine information, including mine equipment information, mine structure information, mine environment information, and user information within the mine. Based on this information, it determines whether any abnormal conditions exist in the mine. When abnormal conditions are found, it identifies the contributing factors. Based on these factors, it determines the corresponding risk level of the abnormal condition and generates anomaly handling strategies. This multi-dimensional approach, utilizing both information from various dimensions and user data, improves the accuracy of anomaly assessment and enhances the reliability and feasibility of the generated anomaly handling strategies.

[0059] based on Figure 1 In addition to the method described herein, this specification also provides some specific implementation methods of this method, which will be described below.

[0060] As one implementation method, optionally, the environmental information described in the embodiments of this specification includes at least oxygen concentration; the user physiological information includes at least blood oxygen saturation; the step of determining whether there is an abnormal condition in the mine based on the mine information and the user information may specifically include: determining whether the oxygen concentration is within a preset concentration range; if the oxygen concentration is within the preset concentration range, then determining whether the blood oxygen saturation is within a preset blood oxygen range.

[0061] In the embodiments of this specification, the preset concentration range can be determined based on expert experience or based on the oxygen concentration in normal air; for example, if the oxygen concentration in normal air is 20.9%, the preset concentration range can be set to 20%-21%. If the oxygen concentration is not within the preset concentration range, it can be determined that there is an abnormal situation of low oxygen in the mine.

[0062] In the embodiments described in this specification, the preset blood oxygen range may be determined based on expert experience; or it may be determined based on the user's blood oxygen saturation range in normal air. If the blood oxygen saturation is within the preset blood oxygen range, it is determined that there is no abnormal condition; if the blood oxygen saturation is not within the preset blood oxygen range, it is determined that the user has an abnormal condition.

[0063] In the embodiments described in this specification, the server can first determine whether the blood oxygen saturation is within a preset blood oxygen range. After confirming that the blood oxygen saturation is within the preset blood oxygen range, it can then determine whether the oxygen concentration is within a preset concentration range. Alternatively, the server can simultaneously determine both the oxygen concentration and the blood oxygen saturation. If either indicator fails to meet the above conditions, it can be determined that an abnormal situation exists in the mine, thereby accurately determining whether an abnormal situation has occurred in the mine.

[0064] As one implementation method, optionally, the method described in this specification for determining the factors causing the abnormal situation if an abnormal situation exists in the mine may specifically include: if the blood oxygen saturation is not within the preset blood oxygen range, determining that the oxygen concentration detected by the first oxygen detection device is abnormal; obtaining the target oxygen concentration detected by the second oxygen detection device; if the target oxygen concentration is within a first concentration range, determining that a first risk level exists in the mine; if the target oxygen concentration is within a second concentration range, determining that a second risk level exists in the mine; the second concentration range is smaller than the first concentration range; the risk of the second risk level is higher than the risk of the first risk level.

[0065] In the embodiments described in this specification, if the blood oxygen saturation is not within the preset blood oxygen range, it means that the oxygen concentration in the area where the worker is located is insufficient to provide enough oxygen for the worker, causing the worker's blood oxygen saturation to be outside the normal range. The term "worker" can be the same concept as the "user" mentioned above, both referring to people in the mine.

[0066] In the embodiments described in this specification, the first oxygen detection device can be an oxygen detection device deployed at a fixed location in the mine. The second oxygen detection device can be a portable oxygen detection device carried by the operator; this oxygen detection device can also send the detected data to the digital twin model, so that the digital twin model can save the relevant oxygen detection data. The digital twin model can be used to assist the server in generating anomaly handling strategies.

[0067] In the embodiments of this specification, the first concentration range and the second concentration range can be determined based on expert experience. The first concentration range can represent the concentration range where the oxygen concentration is lower than the normal oxygen concentration, but workers can still work for a short period of time; the second concentration range can represent the concentration range where the oxygen concentration is lower than the normal oxygen concentration, but insufficient to support workers continuing to work in the area. The first risk level can represent low risk, which can be addressed by investigating the cause of the oxygen concentration reduction and carrying out maintenance; the second risk level can represent high risk, which requires immediate route planning and evacuation of workers from the area.

[0068] In this embodiment, the server can also obtain the operator's blood oxygen saturation within a preset time period through the operator's user terminal; based on the operator's blood oxygen saturation within the preset time period, determine the trend of the operator's blood oxygen saturation change within the preset time period; based on the trend, if it is determined that the operator's blood oxygen saturation change within the preset time period is less than or equal to a preset range, then anomalies can be identified using information from the digital twin model. After identifying the anomalies, they are addressed. If the anomalies are successfully addressed within a set time period, the operator can continue working; if the anomalies are not successfully addressed within the set time period, a safe route can be planned using the digital twin model to prompt the operator to evacuate the work area. Based on the trend, if it is determined that the operator's blood oxygen saturation change within the preset time period exceeds a preset range, a safe route can be planned using the digital twin model to prompt the operator to evacuate the work area. The work area can be a pre-defined area; or it can be obtained based on the area affected by the decrease in oxygen concentration.

[0069] In the embodiments of this specification, if it is necessary to determine abnormal factors through various information in the digital twin model, the server can determine whether the decrease in oxygen concentration is caused by an abnormality in the ventilation system by using the operating parameters of the ventilation system contained in the digital twin model; and / or, by using the mineral types in the geological structure information, determine whether the decrease in oxygen concentration is caused by the oxidation of easily oxidizable oxygen-containing minerals; and / or, by using the goaf in the geological structure information, determine whether the decrease in oxygen concentration is caused by air leakage in the goaf; and / or, by using the microbial information in the microbial detection equipment, determine whether the decrease in oxygen concentration is caused by microbial oxygen consumption, etc. Once the abnormal factors are identified, corresponding measures can be taken to address them so that the oxygen concentration returns to normal levels; for example, if the ventilation rate of the ventilation system is too low, causing a decrease in oxygen concentration, the ventilation rate can be increased; or, if microbial oxygen consumption is causing a decrease in oxygen concentration, calcium hypochlorite can be sprayed on the ventilation tunnel walls for sterilization; or, if easily oxidizable oxygen-containing minerals are oxidizing, causing a decrease in oxygen concentration, an inhibitor can be sprayed to cover the mineral surface, etc.

[0070] As one implementation method, optionally, the environmental information described in the embodiments of this specification includes at least the regional location information of the mine restricted area; the determination of whether there is an abnormal situation in the mine may specifically include: determining whether the user is in the mine restricted area based on the user's location information and the regional location information; the method may further include: if the user is in the mine restricted area, sending a prompt message to the user; the prompt message is used to prompt the user to leave the mine restricted area. The restricted area may include goaf areas, high-risk work areas, and blasting and warning areas, etc.

[0071] As one implementation method, optionally, the mine environment information described in the embodiments of this specification includes at least gas concentration and wind speed; the step of determining whether there is an abnormal condition in the mine may specifically include: determining whether the gas concentration is greater than or equal to a first preset gas concentration; if the gas concentration is greater than or equal to the first preset gas concentration, determining whether the wind speed is less than a preset wind speed; if the wind speed is less than the preset wind speed, determining whether there is an abnormality in the ventilation equipment based on the ventilation equipment information in the equipment information.

[0072] In the embodiments of this specification, the first preset methane concentration can be determined based on expert experience, and may be subject to risks. For example, the first preset methane concentration can be 0.5%, 0.9%, etc. The preset wind speed can be the wind speed under normal ventilation conditions in a mine, determined based on expert experience. If the wind speed is lower than the preset wind speed, it may be due to a problem with the ventilation equipment. Therefore, it is necessary to perform anomaly detection on the ventilation equipment to determine whether the excessive methane concentration is caused by an malfunction in the ventilation equipment.

[0073] As one implementation method, optionally, the ventilation equipment information described in the embodiments of this specification includes at least operating parameter information; the step of determining the factor information causing the abnormal situation may specifically include: if the wind speed parameter in the operating parameter information is abnormal, then determining the factor information as the wind speed parameter; based on the factor information, determining the risk level corresponding to the abnormal situation may specifically include: based on the wind speed parameter, determining the first risk level corresponding to the abnormal situation; based on the risk level, generating an abnormality handling strategy may specifically include: based on the first risk level, adjusting the wind speed of the ventilation equipment.

[0074] In the embodiments of this specification, an abnormal wind speed parameter can indicate that the wind speed of the ventilation equipment is lower than the preset wind speed; the preset wind speed can be determined based on expert experience. The first risk level can indicate that the abnormal situation is in a low-risk state. Adjusting the wind speed of the ventilation equipment, specifically, the server can adjust the wind speed to the first wind speed; after determining that the gas concentration has reached the normal concentration, the wind speed is adjusted to the second wind speed; the second wind speed is lower than the first wind speed; the second wind speed can represent the wind speed under normal ventilation equipment conditions.

[0075] As another implementation, optionally, the ventilation equipment information described in the embodiments of this specification includes at least operating parameter information; the determination of the factor information causing the abnormal situation may specifically include: if the current parameter in the operating parameter information is abnormal, then determining the factor information as the current parameter; determining the risk level as a second risk level based on the current parameter; based on the second risk level, stopping the power supply to the ventilation equipment and generating a safe route, prompting non-essential personnel to evacuate according to the safe route. Non-essential personnel may be those who do not have the ability to directly participate in emergency response or who have professional emergency skills. The risk represented by the second risk level may be higher than the risk represented by the first risk level. The safe route may be a route that can help users escape, output after processing mine structure information, mine environment information, and mine equipment information based on a route planning model.

[0076] As one implementation method, optionally, the mine environment information described in the embodiments of this specification includes at least the gas concentration; the method may further include: determining whether the gas concentration is greater than or equal to a second preset gas concentration; determining the risk level corresponding to the abnormal situation may specifically include: if the gas concentration is greater than or equal to the second preset gas concentration, then determining the second risk level of the abnormal situation; generating an anomaly handling strategy based on the risk level may specifically include: planning a safe route based on the second risk level; prompting the user to evacuate to a safe area according to the safe route.

[0077] In the embodiments of this specification, the second preset gas concentration may be greater than the first preset gas concentration; the second preset gas concentration may represent the gas concentration that reaches a high risk level, and may be determined based on expert experience, such as 1%, 1.2%, etc.

[0078] In the embodiments described in this specification, if the risk level is at the second risk level, non-essential personnel can be prompted to evacuate to a safe zone via a safe route. A safe zone can be an area that ensures user safety, such as a refuge chamber, outside a mine shaft, or an area with a stable structure where dangerous situations are unlikely to occur, etc.

[0079] Alternatively, in another implementation, the embodiments of this specification may also determine whether the gas concentration is greater than or equal to a third preset gas concentration; if the gas concentration is greater than or equal to the third preset gas concentration, the risk level can be determined as the third risk level; the risk represented by the third risk level is greater than the risk represented by the second risk level; based on the third risk level, multiple safe routes are planned; based on the multiple safe routes, all users in the mine are prompted to evacuate to a safe area. The third preset gas concentration can represent the gas concentration that reaches the explosion risk, and can be determined based on expert experience, such as 1.5%, 2%, etc.

[0080] In the embodiments of this specification, the server can also determine whether there is an abnormal situation in the mine based on the roof displacement rate; if the roof displacement rate is greater than or equal to a preset rate, it can be determined that there is an abnormal situation in the mine, and the roof displacement rate can be used as factor information to determine the corresponding risk level, and the corresponding strategy can be determined based on the risk level; for example, if it is the first risk level, the professional user is prompted to carry out support treatment; if it is the second risk level, the user is notified to evacuate.

[0081] In the embodiments described in this specification, the server can also determine whether there are abnormal conditions in the mine based on the frequency of acoustic emission events. Acoustic emission events refer to transient elastic wave phenomena generated by the rapid release of internal energy due to the impact of materials or structures. If the frequency of the acoustic emission event is greater than or equal to a preset frequency, it can be determined that there are abnormal conditions in the mine. The frequency of the acoustic emission event can be used as factor information to determine the corresponding risk level, and a corresponding strategy can be determined based on the risk level. For example, if it is the first risk level, professional users can be prompted to reinforce the structure or materials; if it is the second risk level, an electronic fence system can be used to restrict users from entering the area and guide personnel in the affected area to evacuate. In practical applications, it can also detect the presence of fire and thermal anomalies based on temperature; it can also detect the presence of winch equipment malfunctions based on the vibration acceleration of the winch; it can also detect the presence of drainage system malfunctions based on the rate of increase or decrease of water flow, and so on. These will not be listed here.

[0082] In the embodiments of this specification, under the second risk level, the nearest mine safety exits to each user can be determined, and a safe route containing the mine safety exits can be planned so that each user can escape the mine according to the safe route.

[0083] In the embodiments of this specification, under the third risk level, the distance between the user and the safety exit in the mine can be determined; if the distance between the user and the safety exit is less than a preset distance, a target safety route containing the nearest mine safety exit to the user is determined; based on the target safety route, the user is prompted to escape along the target safety route, so that the user can safely leave the mine and ensure the user's life safety.

[0084] As one implementation method, if the user is far from the safety exit in the mine, other safe zones closest to the user can be identified, such as refuge chambers and enclosed areas. Normal ventilation is not possible in enclosed areas. Optionally, in the embodiments of this specification, the safe zone includes at least an enclosed area; the mine environment information includes at least the oxygen density and oxygen concentration information of the safe zone; the mine structure information includes at least the spatial volume information of the enclosed area; before planning the safe route, the process may further include: obtaining a set oxygen concentration; obtaining a preset rescue duration; determining the user's oxygen consumption rate in a resting state based on the user information; determining the total oxygen content based on the set oxygen concentration, oxygen density, oxygen concentration, and spatial volume information; determining the user's oxygen consumption within the preset rescue duration based on the oxygen consumption rate and the preset rescue duration; determining the preset number of users that the enclosed area can accommodate based on the total oxygen content and the oxygen consumption; and prompting the user to evacuate to the safe zone according to the safe route, which may specifically include: prompting the preset number of users to evacuate to the enclosed area according to the safe route.

[0085] In the embodiments described in this specification, the oxygen concentration can be set based on the respiratory protection standards stipulated by the U.S. Occupational Safety and Health Administration; or it can be determined based on expert experience. The preset rescue duration can be determined based on expert experience; or it can be the longest rescue duration determined based on historical rescue durations. The resting state can represent the user quietly staying in a certain area, in a state of not speaking, not moving, and remaining relatively still. The oxygen consumption rate can be determined based on expert experience; or it can be determined by obtaining the user's historical oxygen consumption rate in the resting state.

[0086] If the safe zone is a refuge chamber, the server can obtain equipment information from the refuge chamber. If the refuge chamber lacks ventilation equipment or the ventilation equipment is malfunctioning, the server can determine the number of users the refuge chamber can accommodate based on the aforementioned method of corresponding enclosed areas of the safe zone, and instruct the corresponding number of users to go to the refuge chamber. If the refuge chamber contains ventilation equipment and the ventilation equipment is functioning normally, the server can determine the number of users the refuge chamber can accommodate based on the volume of the refuge chamber; determine the safe route where the refuge chamber with ventilation equipment is located, and then instruct the number of users the refuge chamber can accommodate to evacuate to the refuge chamber according to the safe route. This allows users to escape to the refuge chamber even when they are far from the safe exit, ensuring their safety.

[0087] In practical applications, during external rescue operations, gaps may appear in the safe area, causing the oxygen content to gradually increase. The server can also send prompts to users to assist in the rescue if the oxygen detection equipment detects a continuous rise in oxygen levels. The server can also send self-rescue measures to users, who can then coordinate with external rescue personnel to assist in the rescue effort.

[0088] In this embodiment of the specification, if an oxygen supply device exists in the enclosed area, an instruction message can be sent to the user in the enclosed area. This instruction message instructs the user to operate the oxygen supply device, enabling it to release oxygen to the user in the enclosed area. If the detected oxygen concentration in the enclosed area is greater than or equal to a preset oxygen concentration, the user's waiting time for rescue can be determined. This waiting time can be the longest time the user needs to wait from the current moment until rescue. The system then determines whether the waiting time is greater than a first preset time. If it is less than or equal to the first preset time, the user is prompted to use a first method to reduce the oxygen concentration. If the waiting time is greater than the first preset time, the system determines whether the waiting time is greater than a second preset time. If the waiting time is less than or equal to the second preset time, the user is prompted to use a second method to reduce the oxygen concentration. If the waiting time is greater than the second preset time, the user is prompted to use a third method to reduce the oxygen concentration. The first method could be to place iron powder in the air, allowing it to rapidly consume oxygen through oxidation. When the oxygen concentration reaches a normal level, the user would be prompted to seal the iron powder to prevent further oxygen consumption. The normal concentration could be determined based on the normal oxygen concentration in the outside air. The second method could be to connect to a nitrogen generator truck, with the server issuing a command to the truck to replenish a preset volume of nitrogen, thus bringing the oxygen concentration in the air to a normal level. The third method could be to use sealed bio-bacterial bags to absorb oxygen, but the bio-bacterial bags should not be exposed.

[0089] As one implementation method, if a user escapes to a safe area underground, such as a confined space or refuge chamber, via a safe route, the user terminal can be processed to maintain normal communication with the outside world. Optionally, in the embodiments of this specification, the anomaly handling strategy includes at least planning a safe route for the user to reach the safe area; the method further includes: identifying each user terminal in the safe area; obtaining the battery usage duration of each user terminal; obtaining a preset rescue duration; determining whether the maximum battery usage duration of each user terminal is greater than the preset rescue duration; if the maximum battery usage duration of each user terminal is greater than the preset rescue duration, then setting the first user terminal among the user terminals to a first state, and setting the other user terminals among the user terminals to a second state; the power consumption rate of the second state is less than the power consumption rate of the first state; if the battery level of the first user terminal is less than or equal to a preset battery level, then setting the second user terminal among the other user terminals to the first state, and setting the first user terminal to the second state.

[0090] The safe zone in the embodiments of this specification can be a refuge chamber in a mine or a confined area, etc. Specifically, the method for determining user terminals in the safe zone involves acquiring the location information of several user terminals and identifying multiple user terminals whose location information is located within the safe zone. The battery usage time can be determined based on the remaining battery power of each user terminal. The first state is a normal state where communication can be maintained. The second state is an energy-saving state where communication is not possible, but the user's physiological condition can be continuously monitored. The preset battery power can be determined based on expert experience. The preset battery power can decrease as the waiting time for rescue decreases. The server can change the state of the user terminals based on the battery power to increase the communication time in the confined area and avoid situations where personnel are out of contact.

[0091] In this embodiment of the specification, if the physiological information of a third user is detected to be inconsistent with preset conditions, and the third user's terminal is in a second state, the terminal can be set to a first state, and a distress message can be sent to an external server. The distress message is used to seek external assistance and may include abnormal information in the user's physiological information and the user's location information. Inconsistent physiological information may include: the user's heart rate being less than or equal to a preset heart rate; the user's blood oxygen saturation being less than or equal to a preset blood oxygen saturation; the user's skin being in an abnormal state, etc. The server can determine the identification information of other fourth user terminals in the first state within the enclosed area, enabling the external server to send rescue instruction information to the fourth user terminals based on the identification information. The rescue instruction information is used to instruct the fourth user to provide rescue assistance to the third user according to the rescue operation instructions contained in the instruction information, thus preventing the third user from being in life-threatening danger.

[0092] The above methods can detect abnormal conditions in the mine from multiple dimensions, improving the accuracy of the detection results. They can also determine the causes of abnormal conditions based on multiple different types of data, identify the corresponding risk levels, and generate accurate anomaly handling strategies. This ensures user safety while also handling abnormal conditions, keeping the mine in a normal state.

[0119] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on its differences from other embodiments. In particular, for... Figure 3 As the device shown is basically similar to the method embodiment, the description is relatively simple, and relevant parts can be found in the description of the method embodiment.

[0120] In the 1990s, improvements to a technology could be clearly distinguished as either hardware improvements (e.g., improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the methodology). However, with technological advancements, many methodological improvements today can be considered direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved methodology into the hardware circuit. Therefore, it cannot be said that a methodological improvement cannot be implemented using hardware physical modules. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logic function is determined by the user programming the device. Designers can program and "integrate" a digital system onto a PLD themselves, without needing chip manufacturers to design and manufacture dedicated integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing integrated circuit chips, this programming is mostly implemented using "logic compiler" software. Similar to the software compiler used in program development, the original code before compilation must also be written in a specific programming language, called a Hardware Description Language (HDL). There are many HDLs, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, and RHDL (Ruby Hardware Description Language). Currently, the most commonly used are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also understand that by simply performing some logic programming on the method flow using one of these hardware description languages ​​and programming it into an integrated circuit, the hardware circuit implementing the logical method flow can be easily obtained.

[0121] The controller can be implemented in any suitable manner. For example, it can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicon Labs C8051F320. A memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also recognize that, in addition to implementing the controller in purely computer-readable program code form, the same functionality can be achieved by logically programming the method steps to make the controller take the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers. Therefore, such a controller can be considered a hardware component, and the means included therein for implementing various functions can also be considered as structures within the hardware component. Alternatively, the means for implementing various functions can be considered as both software modules implementing the method and structures within the hardware component.
