[0015] The following will detail the technical solutions provided in each embodiment of this specification with reference to the accompanying drawings.

[0016] Figure 1 It is a schematic flowchart of a method for handling abnormal conditions in a mine provided in an embodiment of this specification. From a program perspective, the execution entity of the process can be an application server or an application client carrying the program. Such as Figure 1 shown, this method may include the following steps.

[0017] Step 102: Obtain the mine information of the mine.

[0018] Among them, the mine information at least includes mine equipment information, mine structure information, and mine environment information.

[0019] In the embodiments of this specification, the mine equipment information may include hardware equipment information and equipment operation parameter information; the hardware equipment information may include information such as the model, name, shape, operation status of the equipment, and its location in the mine. The types of operation parameter information of different equipment may be different or the same. For example, the operation parameters of ventilation equipment may include information such as wind speed, ventilation rate, and current; the operation parameters of a conveyor belt may include information such as conveyor speed and current.

[0020] In the embodiments of this specification, the mine structure information may include underground building information, mine shape information, location areas of each shaft of the mine, restricted area information, geological information of the mine, and shaft shape information, etc. The mine environment information may include oxygen concentration information, temperature information, humidity information, and gas concentration information in the mine, etc.

[0021] In the embodiments of this specification, the mine structure information and the mine environment information can be obtained through information such as radar, cameras, and sensors; the mine equipment information can be uploaded to the server by the mine equipment itself.

[0022] Step 104: Obtain the user information in the mine.

[0023] Among them, the user information at least includes user location information and user physiological information.

[0024] In the embodiments of this specification, user information can be obtained through a user terminal carried by the user. The user terminal can be a wearable intelligent electronic device, a mobile phone, etc. The user location information can be the coordinate information of the user in the mine. The user physiological information can be information indicating the physiological state of the user. The user physiological information can include heart rate information, blood oxygen information, respiratory rate information, etc.

[0025] Step 106: Determine whether there is an abnormal condition in the mine according to the mine information and the user information.

[0026] In the embodiments of this specification, the abnormal conditions in the mine can include the condition that the physical condition of the workers in the mine is abnormal; it can also include the condition that the equipment in the mine is abnormal; it can also include the condition that the environment in the mine is abnormal; it can also include the condition that the structure in the mine is abnormal, etc.

[0027] Step 108: If there is an abnormal condition in the mine, determine the factor information causing the abnormal condition.

[0028] In the embodiments of this specification, the factor information can include at least one of the root cause and the surface cause of the abnormal condition. The root cause can be the fundamental reason for the occurrence of the abnormal condition. The surface cause can be the superficial reason for the occurrence of the abnormal condition. For example, if the abnormal condition is dust accumulation, which is determined by detecting the dust concentration, then the surface factor can be determined as too high dust concentration; through further investigation, it is determined that due to the abnormal ventilation system, the dust cannot be dispersed, resulting in too high dust concentration, and the root cause is determined as the abnormal ventilation system.

[0029] Step 110: Based on the factor information, determine the risk level corresponding to the abnormal condition.

[0030] In the embodiments of this specification, the risk level can be determined based on the severity indicated by the factor information; the more severe the severity indicated by the factor information, the higher the risk level; the lower the severity indicated by the factor information, the lower the risk level. The severity can be determined based on the degree of harm to the life and health of the user. For example, if the gas concentration is extremely high, there may be an explosion risk, which causes the highest degree of harm to the life and health of the user and is also the most severe, and it can be determined as the highest risk level. The risk level can be multiple levels pre-set based on expert experience.

[0031] Step 112: Generate an abnormal condition handling strategy based on the risk level.

[0032] 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 for generating prompts for the user to perform operations; or it can be a strategy that requires the server and the user to cooperate with each other to complete. During the generation process of the exception handling strategy, corresponding strategies can also be generated based on factor information.

[0033] It should be understood that the order of some steps in the method described in one or more embodiments of this specification can be mutually exchanged according to actual needs, or some of the steps can also be omitted or deleted.

[0034] Figure 1 In the method, by obtaining mine information including mine equipment information, mine structure information, and mine environment information, as well as user information in the mine, and judging whether there is an abnormal situation in the mine according to the mine information and the user information in the mine, when there is an abnormal situation in the mine, the factor information causing the abnormal situation can be determined; based on the factor information, the risk level corresponding to the abnormal situation can be determined, and an exception handling strategy can be generated based on the risk level. Thus, the abnormal situation of the mine can be determined through multi-dimensional information and user information, improving the accuracy of judging the abnormal situation, and further improving the reliability and feasibility of the generated exception handling strategy.

[0035] Based on Figure 1 For the method, embodiments of this specification also provide some specific implementation manners of this method, which will be described below.

[0036] As an implementation manner, optionally, in the embodiments of this specification, the environmental information at least includes oxygen concentration; the user physiological information at least includes blood oxygen saturation; and judging whether there is an abnormal situation in the mine according to the mine information and the user information may specifically include: judging whether the oxygen concentration is within a preset concentration range; if the oxygen concentration is within the preset concentration range, then judging whether the blood oxygen saturation is within a preset blood oxygen range.

[0037] 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 thin oxygen in the mine.

[0038] In the embodiments of this specification, the preset blood oxygen range can be determined based on expert experience; or it can be based on the blood oxygen saturation range of the user in normal air. If the blood oxygen saturation is within the preset blood oxygen range, it is determined that there is no abnormal situation; if the blood oxygen saturation is not within the preset blood oxygen range, it is determined that the user has an abnormal situation.

[0039] In the embodiments of this specification, the server may first determine whether the blood oxygen saturation is within a preset blood oxygen range. After determining that the blood oxygen saturation is within the preset blood oxygen range, it may then determine whether the oxygen concentration is within a preset concentration range. Alternatively, the server may simultaneously determine the oxygen concentration and the blood oxygen saturation. If one of the indicators does not meet the above conditions, it may be determined that there is an abnormal situation in the mine, so as to accurately determine whether an abnormal situation has occurred in the mine.

[0040] As an implementation manner, optionally, in the embodiments of this specification, if there is an abnormal situation in the mine, determining the factor information causing the abnormal situation 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 belongs to the first concentration range, determining that there is a first risk level in the mine; if the target oxygen concentration belongs to the second concentration range, determining that there is a second risk level 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.

[0041] In the embodiments of this specification, the blood oxygen saturation not being within the preset blood oxygen range may indicate that the oxygen concentration in the area where the operator is located is not sufficient to provide sufficient oxygen for the operator, causing the operator's blood oxygen saturation to be within an abnormal range. The operator may be the same concept as the user mentioned above, and both may represent the people in the mine.

[0042] In the embodiments of this specification, the first oxygen detection device may be an oxygen detection device arranged at a fixed position in the mine. The second oxygen detection device may be a portable oxygen detection device carried by the operator; this oxygen detection device may also send the detected data to the digital twin model, facilitating the digital twin model to save relevant oxygen detection data. The digital twin model may be used to assist the server in generating an abnormal situation handling strategy.

[0043] In the embodiments of this specification, the first concentration range and the second concentration range may be determined based on expert experience. The first concentration range may indicate a concentration range where the oxygen concentration is lower than the normal oxygen concentration, but the operator can still work for a short time; the second concentration range may indicate a concentration range where the oxygen concentration is lower than the normal oxygen concentration, but it is not sufficient to support the operator to continue working in this area. The first risk level may indicate a low risk, and the cause of the reduced oxygen concentration may be investigated and repaired; the second risk level may indicate a high risk, and a route needs to be immediately planned to arrange the operator to evacuate from this area.

[0044] In the embodiments of this specification, the server can also obtain the blood oxygen saturation of the operator within a preset time period through the operator's user terminal; based on the blood oxygen saturation of the operator within the preset time period, determine the change trend of the change range of the blood oxygen saturation of the operator within the preset time period; based on the change trend, if it is determined that the change range of the blood oxygen saturation of the operator within the preset time period is less than or equal to the preset range, abnormal factors can be determined through various information in the digital twin model. After determining the abnormal factors, deal with the abnormal factors. If the abnormal factors are successfully processed within the set duration, the operator can continue to work; if the abnormal factors are not successfully processed within the set duration, a safe route can be planned using the digital twin model to prompt the operator to evacuate the work area. Based on the change trend, if it is determined that the change range of the blood oxygen saturation of the operator within the preset time period is greater than the 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 preset area; or it can be obtained based on the area affected by the decrease in oxygen concentration.

[0045] 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 abnormal operation of the ventilation system through the operation parameters of the ventilation system included in the digital twin model; and / or, determine whether the decrease in oxygen concentration is caused by the oxidation of oxygen-containing minerals that are easy to oxidize through the mineral types in the geological structure information; and / or, determine whether the decrease in oxygen concentration is caused by air leakage in the goaf through the goaf in the geological structure information; and / or, determine whether the decrease in oxygen concentration is caused by microbial oxygen consumption through the microbial information in the microbial detection equipment, and so on. After determining the abnormal factors, corresponding measures can be taken to make the oxygen concentration reach the normal level; for example, if the ventilation rate of the ventilation system is too low to reduce the oxygen concentration, the ventilation rate can be increased; or, if there is microbial oxygen consumption to reduce the oxygen concentration, calcium hypochlorite can be sprayed on the ventilation roadway wall for sterilization; or, if there is oxidation of oxygen-containing minerals that are easy to oxidize to reduce the oxygen concentration, an inhibitor can be sprayed to cover the mineral surface, and so on.

[0046] As an implementation method, optionally, the environmental information in the embodiments of this specification at least includes the regional location information of the mine restricted area; the judgment of whether there is an abnormal situation in the mine can specifically include: based on the user location information and the regional location information, judge whether the user is in the mine restricted area; the method can also include: if the user is in the mine restricted area, send a prompt message to the user; the prompt message is used to prompt the user to leave the mine restricted area. Among them, the restricted area can include the goaf, high-risk operation area, blasting and warning area, and so on.

[0047] As an implementation manner, optionally, the mine environment information described in the embodiments of the present specification at least includes gas concentration and wind speed; judging whether there is an abnormal condition in the mine may specifically include: judging 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, then judging whether the wind speed is less than a preset wind speed; if the wind speed is less than the preset wind speed, then based on the ventilation equipment information in the equipment information, judging whether there is an abnormality in the ventilation equipment.

[0048] In the embodiments of the present specification, the first preset gas concentration can be determined based on expert experience in risky situations. For example, the first preset gas concentration can be 0.5%, 0.9%, etc. The preset wind speed can be the wind speed under normal ventilation in the mine determined based on expert experience. When the wind speed is less than the preset wind speed, it may be due to problems with the ventilation equipment. Therefore, it is necessary to detect abnormalities in the ventilation equipment, and then it can be determined whether the high gas concentration is caused by abnormal ventilation equipment.

[0049] As an implementation manner, optionally, the ventilation equipment information described in the embodiments of the present specification at least includes operation parameter information; determining the factor information causing the abnormal condition may specifically include: if the wind speed parameter in the operation 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 condition may specifically include: based on the wind speed parameter, determining the first risk level corresponding to the abnormal condition; based on the risk level, generating an abnormal handling strategy may specifically include: based on the first risk level, adjusting the wind speed of the ventilation equipment.

[0050] In the embodiments of the present specification, an abnormal wind speed parameter can indicate that the wind speed of the ventilation equipment is less 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 condition 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 reaches the normal concentration, adjust the wind speed to the second wind speed; the second wind speed is less than the first wind speed; the second wind speed can represent the wind speed when the ventilation equipment is normal.

[0051] As another implementation, optionally, the ventilation equipment information described in the embodiments of this specification at least includes operation parameter information; the determination of the factor information causing the abnormal condition may specifically include: if the current parameter in the operation parameter information is abnormal, determining the factor information as the current parameter; determining the risk level as the 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, and 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 handling or 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 after processing the mine structure information, mine environment information, mine equipment information, etc. based on a route planning model.

[0052] As an implementation, optionally, the mine environment information described in the embodiments of this specification at least includes gas concentration; the method may further include: determining whether the gas concentration is greater than or equal to a second preset gas concentration; the determination of the risk level corresponding to the abnormal condition may specifically include: if the gas concentration is greater than or equal to the second preset gas concentration, determining the abnormal condition as the second risk level; the generation of an abnormal 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.

[0053] 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 reaching a high-risk level and may be determined based on expert experience, such as 1%, 1.2%, etc.

[0054] In the embodiments of this specification, if the risk level is at the second risk level, non-essential personnel may be prompted to evacuate from the safe route to a safe area. The safe area may be an area that can ensure the safety of users, such as a refuge chamber, outside the mine, an area with a stable structure and not prone to dangerous conditions, etc.

[0055] As another implementation, optionally, in the embodiments of this specification, it may also be determined 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 may 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; all users in the mine are prompted to evacuate to a safe area based on the multiple safe routes. The third preset gas concentration may represent the gas concentration reaching an explosion risk and may be determined based on expert experience, such as 1.5%, 2%, etc.

[0056] 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 the 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, professional users can be prompted to carry out support treatment; if it is the second risk level, users can be notified to evacuate.

[0057] In the embodiments of this specification, the server can also determine whether there is an abnormal situation in the mine based on the frequency of acoustic emission events; an acoustic emission event refers to a transient elastic wave phenomenon generated by the rapid release of internal energy in a material or structure due to stress; if the frequency of acoustic emission events is greater than or equal to the preset frequency, it can be determined that there is an abnormal situation in the mine, and the frequency of acoustic emission events 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, professional users can be prompted to reinforce the structure or material; if it is the second risk level, the user's entry into this area can be restricted through the electronic fence system, and the personnel in the affected area can be guided to evacuate. In practical applications, it is also possible to detect whether there are fire and thermal anomalies based on temperature; it is also possible to detect whether there are abnormal conditions in the winch equipment based on the vibration acceleration of the winch; it is also possible to detect whether there are abnormal conditions in the drainage system based on the rising rate or falling rate of the water flow, and so on. They are not listed one by one here.

[0058] In the embodiments of this specification, in the case of the second risk level, the mine safety exits that are relatively close to each user can be determined, and a safety route including the mine safety exits can be planned, so that each user can escape from the mine according to the safety route.

[0059] In the embodiments of this specification, in the case of 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 in the mine is less than the preset distance, the target safety route including the mine safety exit closest to the user in the safety route can be determined; based on the target safety route, the user can be prompted to escape according to the target safety route, so that the user can leave the mine safely and ensure the user's life safety.

[0060] As an implementation, if the user is far away from the safety exit in the mine, other safety areas closest to the user can be determined, such as safety areas like refuge chambers and sealed areas. Normal ventilation cannot be carried out in the sealed area. Optionally, the safety area described in the embodiments of this specification at least includes the sealed area; the mine environment information at least includes the oxygen density information and oxygen concentration information of the safety area; the mine structure information at least includes the spatial volume information of the sealed area; before planning the safe route, it may further include: obtaining a set oxygen concentration; obtaining a preset rescue duration; based on the user information, determining the oxygen consumption rate of the user in a resting state; based on the set oxygen concentration, oxygen density information, oxygen concentration information, and spatial volume information, determining the total oxygen content; based on the oxygen consumption rate and the preset rescue duration, determining the oxygen consumption of the user within the preset rescue duration; based on the total oxygen content and the oxygen consumption, determining the preset number of users that the sealed area can accommodate; the prompting the user to evacuate to the safety area along the safe route may specifically include: prompting the users corresponding to the preset number of users that can be accommodated to evacuate to the sealed area along the safe route.

[0061] In the embodiments of this specification, the set oxygen concentration can be determined based on the respiratory protection standards stipulated by the Occupational Safety and Health Administration of the United States; or, it can be determined based on expert experience. The preset rescue duration can be determined based on expert experience; or, it can also be the longest rescue duration determined based on historical rescue durations. The resting state can indicate that the user stays quietly in a certain area, without talking, moving, and maintaining a relatively static state. The oxygen consumption rate can be determined based on expert experience; or, it can also be determined by obtaining the oxygen consumption rate of the user in the historical resting state.

[0062] If the safety area is a refuge chamber, the server can obtain the equipment information in the refuge chamber. If there is no ventilation equipment in the refuge chamber or the ventilation equipment cannot operate, etc., the number of users that the refuge chamber can accommodate can be determined based on the method corresponding to the sealed area of the above safety area, and the corresponding number of users can be instructed to go to the refuge chamber. If there is a ventilation equipment in the refuge chamber and the ventilation equipment is normal, the number of users that the refuge chamber can accommodate can be determined 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 users corresponding to the number of users that the refuge chamber can accommodate to evacuate to the refuge chamber along this safe route for refuge, so that the user can escape to the refuge chamber when the distance from the safety exit is far, ensuring life safety.

[0063] In practical applications, during the external rescue process, there may be gaps in the safe area, causing the oxygen content in the safe area to gradually increase. When the server detects that the oxygen content continues to rise based on the oxygen detection device, it can send a prompt message for cooperating with the rescue to each user; the server can send self-rescue measures to each user, and the user can cooperate with the external rescue personnel for auxiliary rescue from the inside based on the self-rescue measures.

[0064] In the embodiments of this specification, if there is an oxygen supply device in the enclosed area, an instruction message can be sent to the users in the enclosed area; the instruction message is used to instruct the users to operate the oxygen supply device so that the oxygen supply device can release oxygen outward to provide oxygen for the users in the enclosed area. If it is detected that the oxygen concentration in the enclosed area is greater than or equal to the preset oxygen concentration, the waiting rescue duration of the user can be determined. The waiting rescue duration can be the longest duration required for the user to wait until rescue from the current moment; it is judged whether the waiting rescue duration is greater than the first preset duration; if it is less than or equal to the first preset duration, the user is prompted to use the first method to reduce the oxygen concentration; if the waiting rescue duration is greater than the first preset duration, it is judged whether the waiting rescue duration is greater than the second preset duration. If the waiting rescue duration is less than or equal to the second preset duration, the user is prompted to use the second method to reduce the oxygen concentration; if the waiting rescue duration is greater than the second preset duration, the user is prompted to use the third method to reduce the oxygen concentration. Among them, the first method can be to place iron powder in the air so that the iron powder can quickly consume oxygen through oxidation. When it is detected that the oxygen concentration reaches the normal concentration, the user is prompted to seal the iron powder to avoid oxygen consumption; the normal concentration can be determined based on the oxygen concentration in the normal external air; the second method can be to connect a nitrogen production vehicle, and the server issues an order to the nitrogen production vehicle to supplement a preset volume of nitrogen so that the oxygen concentration in the air reaches the normal concentration; the third method can be to use a sealed biological bacteria package to absorb oxygen, but it is necessary to avoid the exposure of the biological bacteria package.

[0065] As an implementation, if the user escapes to a safe area such as an enclosed area or a refuge chamber underground through 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 abnormal handling strategy at least includes planning a safe route for the user to reach the safe area; the method further includes: determining each user terminal in the safe area; obtaining the power consumption duration of each user terminal; obtaining a preset rescue duration; determining whether the maximum power consumption duration among each user terminal is greater than the preset rescue duration; if the maximum power consumption duration among each user terminal is greater than the preset rescue duration, setting the first user terminal among each user terminal to a first state, and setting the other user terminals among each user terminal to a second state; the power consumption rate of the second state is less than that of the first state; if the power of the first user terminal is less than or equal to the preset power, setting the second user terminal among the other user terminals to the first state, and setting the first user terminal to the second state.

[0066] The safe area in the embodiments of this specification can be a safe area such as a refuge chamber and an enclosed area underground. The method for determining user terminals in the safe area is specifically to obtain the location information of several user terminals; and determine the multiple user terminals whose location information is located in the location area of the safe area. The power consumption duration can be determined based on the remaining power of each user terminal. The first state is the normal state capable of maintaining communication. The second state is the energy-saving state that cannot communicate but can continuously monitor the user's physiological condition. The preset power can be determined based on expert experience. The preset power can decrease as the waiting rescue duration decreases. The server can change the state of the user terminal based on the power situation, increase the communication duration in the enclosed area, and avoid the situation of personnel losing contact.

[0067] In the embodiments of this specification, if it is detected that the physiological information of the third user does not meet the preset conditions and the third user terminal of the third user is in the second state, the third user terminal can be set to the first state, and a help-seeking message can be sent to an external server; the help-seeking message is a message used to seek help externally; the help-seeking message can include the abnormal information in the user physiological information and the user location information. The user physiological information not meeting the preset conditions can include: the user heart rate information is less than or equal to the preset heart rate information; the user blood oxygen saturation information is less than or equal to the preset blood oxygen saturation information; the user's skin is in an abnormal state, and so on. The server can determine the identification information of other fourth user terminals in the closed area that are in the first state, so that the external server can send a rescue instruction message to the fourth user terminal based on the identification information; the rescue instruction message is used to instruct the fourth user to provide rescue help to the third user according to the rescue operation instructions contained in the instruction message, to prevent the third user from being in danger of life.

[0068] Through the above method, the abnormal conditions in the mine can be detected through multiple dimensions, improving the accuracy of the detection results; it is also possible to determine the causes of the abnormal conditions based on multiple different types of data, determine the corresponding risk levels, generate accurate abnormal handling strategies, and while ensuring the safety of users, it is also possible to handle the abnormal conditions so that the mine is in a normal condition.

[0080] Each embodiment in this specification is described in a progressive manner. For the same and similar parts among the embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments. In particular, for Figure 3 the device shown, since it is basically similar to the method embodiment, the description is relatively simple. For the relevant parts, reference can be made to the partial description of the method embodiment.

[0081] In the 1990s, it was obvious to distinguish whether an improvement to a technology was an improvement in hardware (e.g., improvement to the circuit structures such as diodes, transistors, switches, etc.) or an improvement in software (improvement to the method flow). However, with the development of technology, many improvements to method flows today can be regarded as direct improvements to hardware circuit structures. Almost all designers obtain the corresponding hardware circuit structures by programming the improved method flows into the hardware circuits. Therefore, it cannot be said that an improvement to a method flow cannot be implemented with a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can program by themselves to "integrate" a digital system on a piece of PLD without having to ask a chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in program development and writing. The original code before compilation also has to be written in a specific programming language, which is called a hardware description language (HDL), and there is not only one kind of HDL, but many kinds, 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, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones currently are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also be aware that by simply making a little logical programming of the method flow with the above-mentioned several hardware description languages and programming it into the integrated circuit, it is easy to obtain the hardware circuit that implements the logical method flow.

[0082] The controller can be implemented in any suitable manner. For example, the controller can take the form of, for example, a microprocessor or a processor and a computer-readable medium storing computer-readable program code (such as software or firmware) executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of the controller include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in the form of pure computer-readable program code, it is entirely possible to logically program the method steps to enable the controller to be implemented in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, and embedded microcontrollers, etc., to achieve the same function. Therefore, such a controller can be considered a hardware component, and the devices included therein for implementing various functions can also be regarded as the structures within the hardware component. Or even, the devices for implementing various functions can be regarded as either software modules for implementing the method or structures within the hardware component.
