Description

Technical Field

[0001] The present disclosure relates to an elevator maintenance management system. Background Art

[0002] When a failure occurs in an elevator device, even if the failure is remotely diagnosed, elevator maintenance management personnel can go to the site to repair the failure after the failure occurs. Therefore, passengers cannot use the elevator during the repair period. Therefore, it is quite important to predict elevator failures in advance.

[0007] Technical Problem

[0008] The present disclosure provides an elevator maintenance management system that senses signs of elevator failures.

[0009] The present disclosure provides an elevator maintenance management system that improves the accuracy of the judgment result for judging signs of elevator failures.

[0010] The present disclosure provides an elevator maintenance management system that sends an attention signal or a warning signal before an elevator actually fails so that maintenance and repair can be performed.

[0011] Solution to the Problem

[0012] The present disclosure provides an elevator maintenance management system, which is characterized by including a maintenance terminal carried by maintenance staff and a central management server. The central management server collects and stores the operation status signals of the elevator from the elevator control panel, analyzes the collected and stored operation status signals, judges the failure sign information according to each inspection item of the elevator, and transmits it to the maintenance terminal. The maintenance terminal displays the judgment result of the failure sign information of each inspection item of the elevator.

[0013] At this time, the failure sign information may include a failure attention state and a failure warning state. In addition, in the maintenance terminal, an attention warning display screen is formed. The attention warning display screen displays the judgment results of the failure attention and failure warning states of each inspection item of the elevator, and an evaluation input part for maintenance staff to input evaluation opinions on the judgment results of the failure attention and failure warning states displayed according to each inspection item of the elevator can be formed in the attention warning display screen.

[0014] In addition, the central management server collects and stores the evaluation opinions input through the evaluation input unit, and can judge the failure attention and failure warning status of the inspection items regarding the elevator by considering the evaluation opinions collected and stored in the past.

[0015] In addition, a regular inspection creation screen for inputting the regular inspection process of the elevator is formed on the maintenance terminal. An attention warning confirmation button for confirming the judgment result of the failure attention and failure warning status is formed on the regular inspection creation screen. When the attention warning confirmation button is operated, the attention warning display screen can be displayed.

[0018] In addition, the first judgment criterion includes: a first critical value criterion for setting an allowable range of the signal value of the action state signal for each inspection item; and a first critical number criterion for setting an allowable range of the number of times the signal value of the action state signal for each inspection item exceeds the first critical value criterion. The attention warning judgment unit can compare the action state signal information of each inspection item stored in the action signal storage unit with the first critical number criterion to judge whether it corresponds to the failure attention state for each inspection item.

[0019] In addition, the attention warning judgment unit can newly set at least one of the first critical value criterion and the first critical number criterion based on the evaluation opinion information stored in the evaluation opinion storage unit.

[0020] In addition, the second judgment criterion includes: a second critical value criterion for setting an allowable range of signal values of the operation status signals for each of the inspection items; and a second critical number criterion for setting an allowable range of the number of times the signal values of the operation status signals for each of the inspection items exceed the second critical value criterion. At least one of the second critical value criterion and the second critical number criterion has a larger allowable range than the first critical value criterion and the first critical number criterion. The attention warning judgment unit can compare the operation status signal information of each inspection item stored in the operation signal storage unit with the second critical number criterion, and judge whether each inspection item corresponds to a failure warning state.

[0021] In addition, the attention warning judgment unit can newly set at least one of the second critical value criterion and the second critical number criterion based on the evaluation opinion information stored in the evaluation opinion storage unit.

[0059] Figure 1 It is a diagram conceptually showing the overall configuration of an elevator maintenance management system according to an embodiment of the present disclosure. Figure 2 It is a diagram conceptually showing the overall configuration of an elevator maintenance management system according to another embodiment of the present disclosure.

[0060] The elevator maintenance management system according to an embodiment of the present disclosure may include a maintenance terminal (500) carried by maintenance staff and a central management server (400). The central management server (400) collects and stores the operation status signals of the elevator from the elevator control panel (100), and analyzes them to judge the fault indication information according to each inspection item of the elevator. The fault indication information may include a fault attention state and a fault warning state. The description of the fault attention state and the fault warning state will be described below.

[0061] The central management server (400) can transmit the judgment results of the fault attention and fault warning status to the maintenance terminal (500). The maintenance terminal (500) can display on the screen the judgment results of the fault attention and fault warning status of each inspection item of the elevator received from the central management server (400).

[0062] In this embodiment, the case where the central management server (400) judges the fault sign and transmits the judgment result to the maintenance terminal (500) will be described. On the other hand, as another embodiment, the fault sign can also be judged by at least one of the elevator control panel (100), the central management server (400), and the maintenance terminal (500). When judging the fault sign by more than two components, the reliability of the fault judgment can be improved.

[0063] First, the overall system configuration will be described. Generally, an elevator may include a control panel (100) for controlling the operating state of the elevator. The control panel (100) receives various operating state signals generated from the elevator. These operating state signals may include normal signals, abnormal signals, and fault signals. A normal signal may mean a signal generated when the corresponding inspection part is normal. A fault signal may mean a signal generated when a fault occurs in the corresponding inspection part. An abnormal signal may mean a signal generated when the operating state signal occurring in the corresponding inspection part exceeds the normal range but is not completely in a fault state. In one embodiment, the abnormal signal may include an attention signal and a warning signal. In one embodiment, the operating state signals may include signals related to the actual operation of elevator components.

[0064] The operating state signals of the elevator may be generated by a plurality of sensors provided in the elevator. The control panel (100) can receive the operating state signals of the elevator through such sensors. All signals regarding the operating state of the elevator can be received and stored in the control panel (100).

[0065] The operating state signals of the elevator can be transmitted to the central management server (400) in real time through the communication unit (200). As Figure 1 shown, in the communication unit (200), it can communicate with the central management server (400) through its own modem (310) and transmit the operating state signal information of the elevator. As Figure 2 shown, when there is a separate monitoring panel, the communication unit (200) can communicate with the central management server (400) through the monitoring panel server (320) and transmit the corresponding information.

[0066] The central management server (400) can store the operation status signals of the elevator transmitted from the elevator control panel (100) through the communication unit (200). The central management server (400) analyzes the operation status signals and can judge the fault attention and fault warning status according to each inspection item of the elevator. In one embodiment, a terminal (not shown) can sense the information of the control panel (100) and send it to the central management server (400).

[0067] Such a central management server (400) can be applied to various forms of servers according to the needs of users. In addition, the central management server (400) can be connected to the maintenance terminal (500) through the Internet. Information such as the operation status signal information of the elevator can be transmitted from the central management server (400) to the maintenance terminal (500). In the maintenance terminal (500), the operation status signal information of the elevator and the judgment results of the fault attention and fault warning status, etc. can be received by connecting to the central management server (400) through an application. More specifically, in the maintenance terminal (500), the number of fault attention or fault warning codes accumulated by each part of the elevator, the expected reasons, and guidelines for necessary confirmation items, etc. provided through the Application Program Interface (API) at the central management server (400) can be displayed

[0068] The fault attention (Warning) status may mean that a sign of elevator fault occurrence is sensed and the status of the corresponding inspection part needs to be checked with attention. The fault warning (Alert) status may mean that a sign of elevator fault occurrence is sensed to be higher than the fault attention status and the status of the corresponding inspection part needs to be checked with more attention. For example, when the central management server (400) senses an abnormal signal in the operation status signal of the elevator, it can consider the signal value and occurrence times of the abnormal signal to judge the fault attention status or the fault warning status. Of course, when the central management server (400) senses a fault signal in the operation status signal of the elevator, it will generate a separate fault occurrence signal and handle the corresponding fault signal through a fault handling process

[0069] On the other hand, for example, the fault attention status may be something that needs to be selectively confirmed when maintenance staff go out on the grounds of inspection, etc. The fault warning status may be something that must be confirmed when maintenance staff go out on the grounds of inspection, etc. Of course, when a fault is sensed, the maintenance terminal (500) can display a notice that they must go out

[0070] In the present disclosure, when an abnormal signal rather than a fault signal is sensed in the operation status signal of an elevator, the fault attention and fault warning status can be judged based on this. By providing the judgment result to the maintenance terminal (500), it is possible to guide maintenance staff to check the inspection items of the fault attention and fault warning status when visiting the corresponding elevator site. Therefore, elevator failures can be prevented in advance.

[0071] Hereinafter, the detailed configuration of the elevator maintenance management system according to an embodiment of the present disclosure will be described in more detail.

[0072] Figure 3 It is a block diagram functionally showing the configuration of the central management server and the maintenance terminal of the elevator maintenance management system according to an embodiment of the present disclosure. Figure 4 It is an operation flowchart showing the process of judging the fault attention and fault warning status of the elevator maintenance management system according to the operation process according to an embodiment of the present disclosure. Figure 5 It is a diagram exemplarily showing the regular inspection creation screen and the attention warning confirmation button displayed on the maintenance terminal according to an embodiment of the present disclosure. Figure 6 It is a diagram exemplarily showing the attention warning display screen and the evaluation input part displayed on the maintenance terminal according to an embodiment of the present disclosure.

[0073] The elevator maintenance management system according to an embodiment of the present disclosure may include a maintenance terminal (500) and a central management server (400).

[0074] The central management server (400) may include a first communication unit (401a), an operation signal storage unit (402), an attention warning judgment unit (404), and a second communication unit (401b). In addition, the central management server (400) may further include an evaluation opinion storage unit (403).

[0075] The first communication unit (401a) communicates with the communication unit (200) of the elevator and can receive in real time the operation status signal recorded on the elevator control panel (100). The operation status signal of the elevator received through the first communication unit (401a) can be stored in the operation signal storage unit (402) of the central management server (400). The operation status signal of the elevator may include various operation status signals such as the speed of the elevator, the floor number, the door operation status, and the sensing signals of various sensors.

[0076] The operation signal storage unit (402) can classify and store the operation status signal information of the elevator collected from the elevator control panel (100) according to each inspection item of the elevator through the first communication unit (401a). The inspection items of the elevator can be various inspection items such as the traction motor, inverter, main rope, door drive motor, floor sensor, etc. set in advance according to the needs of the user. The operation signal storage unit (402) can separately extract the signals related to these inspection items from the operation status signals of the elevator collected from the elevator control panel (100), classify them, and store them according to each inspection item.

[0077] The attention warning judgment unit (404) can compare the operation status signal information of each inspection item stored in the operation signal storage unit (402) with the first judgment criterion and the second judgment criterion set for each inspection item to judge the fault attention and fault warning status. The judgment result of the attention warning judgment unit (404) can be transmitted to the maintenance terminal (500) through the second communication unit (501b).

[0078] The second communication unit (501b) can communicate with the maintenance terminal (500) and receive the information request signal of the maintenance terminal (500). The second communication unit (501b) can transmit the judgment result of the attention warning judgment unit (404) to the maintenance terminal (500).

[0079] Regarding the judgment result of the attention warning judgment unit (404), the maintenance staff can store the evaluation opinion information input through the maintenance terminal (500) according to each inspection item. The attention warning judgment unit (404) reflects these evaluation opinion information during the process of judging the fault attention and fault warning status for judgment.

[0080] To elaborate in more detail, such as Figure 4As shown, first, the central management server (400) can collect and store the elevator operation status signal (S10) from the elevator control panel (100). The central management server (400) can analyze the stored operation status signal and judge the fault attention and fault warning status (S20) according to each inspection item of the elevator. The process of judging the fault attention and fault warning status (S20) includes steps S21 to S25. First, the central management server (400) can analyze the operation status signal of each inspection item of the elevator and judge whether it corresponds to the fault attention status (S21). If the central management server (400) does not correspond to the fault attention status, the central management server (400) can judge it as normal (S23). If it corresponds to the fault attention status, the central management server (400) can analyze the corresponding operation status signal and judge whether it corresponds to the fault warning status (S22). If it does not correspond to the fault warning status, the central management server (400) judges it as the fault attention status (S25), and if it corresponds to the fault warning status, the central management server (400) can judge it as the fault warning status (S24). As described above, after judging the fault attention and fault warning status (S20), the corresponding judgment result can be transmitted from the central management server (400) to the maintenance terminal (500) (S30). The maintenance terminal (500) can display the judgment result of the received fault attention and fault warning status (S40).

[0081] During the use of the elevator, the elevator operation status signal can continue to be collected and stored. In addition, during the use of the elevator, whenever a new operation status signal is collected and stored, the attention warning judgment unit (404) can judge the fault attention and fault warning status. The attention warning judgment unit (404) has been programmed with a judgment method and can also be included in the control panel and the maintenance terminal in addition to the central management server.

[0082] The judgment process (S20) of the attention warning judgment unit (404) will be described in more detail. The attention warning judgment unit (404) can compare the operation status signal information of each inspection item stored in the operation signal storage unit (402) with the first judgment criterion set for each inspection item to judge whether the corresponding inspection item is in the fault attention status (S21). When the attention warning judgment unit (404) judges it as the fault attention status, it can compare the corresponding operation status signal information with the second judgment criterion set for each inspection item to judge whether the corresponding inspection item is in the fault warning status (S22).

[0083] The first judgment criterion may include: a first critical value criterion for setting an allowable range of signal values of the operation status signals for each inspection item; and a first critical number criterion for setting an allowable range of the number of times the signal values of the operation status signals for each inspection item exceed the first critical value criterion. The attention warning judgment unit (404) may compare the operation status signal information of each inspection item stored in the operation signal storage unit (402) with the first critical number criterion, and judge whether it corresponds to a fault attention state for each inspection item. That is, when the number of times the signal value of the operation status signal exceeds the first critical value criterion exceeds the first critical number criterion, the attention warning judgment unit (404) may judge it as a fault attention state.

[0084] The second judgment criterion may include: a second critical value criterion for setting an allowable range of signal values of the operation status signals for each inspection item; and a second critical number criterion for setting an allowable range of the number of times the signal values of the operation status signals for each inspection item exceed the second critical value criterion. The attention warning judgment unit (404) may compare the operation status signal information of each inspection item stored in the operation signal storage unit (402) with the second critical number criterion, and judge whether it corresponds to a fault warning state for each inspection item. That is, when the number of times the signal value of the operation status signal exceeds the second critical value criterion exceeds the second critical number criterion, it may be judged as a fault warning state.

[0085] At least one of the second critical value criterion and the second critical number criterion may have a larger allowable range than the first critical value criterion and the first critical number criterion.

[0086] For example, when the current value of the door drive motor is set to a normal range of up to 100A and a fault range of 200A or more, if the current value of the door drive motor is from 0A to 100A, it is a normal signal, if it is 200A or more, it is a fault signal, and if it is from 101A to 200A, it may correspond to an abnormal signal. In this case, the first critical value for judging the fault attention state may be set to 100A, and the first critical number may be set to, for example, 300 times. The second critical value for judging the fault warning state may be set to the same 100A as the first critical value. The second critical number may be set to 400 times, which is greater than the first critical number. Of course, the second critical value may also be set to 150A, which is greater than the first critical value, and the second critical number is set to 300 times, which is equal to the first critical number. On the contrary, the second critical value may be set to 150A, which is greater than the first critical value, and the second critical number may be set to 400 times, which is greater than the first critical number. These critical value criteria and critical number criteria are exemplary and can be set diversely according to the needs of users.

[0087] As described above, in the state where the first judgment criterion and the second judgment criterion are set, if the number of times the current value of the door drive motor is sensed to be between 101A and 200A is 300 times or more, the attention warning judgment unit (404) can judge that the door drive motor is in a fault attention state. After that, as the usage time increases, if the number of times the current value of the door drive motor is sensed to be between 101A and 200A is 400 times or more, the attention warning judgment unit (404) can judge that the door drive motor is in a fault warning state. At this time, the time range of the number of times the current value of the door drive motor is between 101A and 200A can be set as the time range from the new setting date of the corresponding inspection item to the current time, but it can also be set as the time range within a certain time from now, for example, the period from now to 30 days ago. That is, the attention warning judgment unit (404) can limit the number of times the signal value of the elevator's operation state signal exceeds the first critical value criterion or the second critical value criterion to the number of times sensed within the preset specified period, so as to judge the fault attention and fault warning states.

[0088] In the above-described case, although the door drive motor has not failed, abnormal signals beyond the normal range occur repeatedly, so it can be judged that a fault sign has occurred. And the central management server (400) can judge whether it is in a fault attention state or a fault warning state through the first judgment criterion and the second judgment criterion, and notify the maintenance staff of the fault sign state. Therefore, even if no fault has occurred, the central management server (400) can sense the fault sign and guide the maintenance staff to check the corresponding inspection item. In addition, inspection measures can be completed before a fault occurs, thus preventing faults.

[0089] On the other hand, the central management server (400) can include the evaluation opinion storage unit (403) as described above. The attention warning judgment unit (404) can judge the fault attention and fault warning states by reflecting the evaluation opinion information of the maintenance staff stored in the evaluation opinion storage unit (403). At this time, the attention warning judgment unit (404) can newly set the first judgment criterion and the second judgment criterion by reflecting the evaluation suggestion information. In addition, the attention warning judgment unit (404) can judge the fault attention and fault warning states based on the newly set judgment criteria.

[0090] To elaborate in more detail, first, the maintenance terminal (500) can include a terminal communication unit (501), a display unit (502), an input unit (503), and a control unit (504), as Figure 3 shown.

[0091] The input unit (503) is formed on the maintenance terminal (500) and can be formed by means of touch operations on a touch panel or in various forms such as separate physical buttons, etc., so that maintenance staff can perform input operations.

[0092] The display unit (502) displays the operation status signal information of the elevator transmitted from the central management server (400), the fault attention and fault warning judgment result information, etc., and can be formed as a display screen formed on the maintenance terminal.

[0093] The terminal communication unit (501) can communicate with the second communication unit (401b) of the central management server (400), and transmit an information request signal, etc. to the central management server (400) or receive the fault attention and fault warning judgment result information, etc. from the central management server (400).

[0094] The control unit (504) can perform operation control on the input unit (503), the display unit (502) and the terminal communication unit (501) of the maintenance terminal (500). When a maintenance staff generates an input signal through the input unit (503), the control unit (504) can perform operation control by transmitting an information request signal corresponding to the corresponding input signal to the central management server (400) through the terminal communication unit (501). According to the transmission of these information request signals, the fault attention and fault warning judgment result information, etc. can be received from the central management server (400) through the terminal communication unit (501). The control unit (504) can perform operation control by displaying the fault attention and fault warning judgment result information, etc. received from the central management server (400) on the display unit (502).

[0095] The display unit (502) of the maintenance terminal (500) may include a caution warning display screen (530), and the caution warning display screen (530) displays the judgment results of the fault attention and fault warning states for each inspection item of the elevator, as Figure 6 shown. The judgment results of the fault attention and fault warning states transmitted from the central management server (400) can be displayed on the caution warning display screen (530).

[0096] The display unit (502) of the maintenance terminal (500) may include a regular inspection creation screen (510) for inputting the regular inspection process of the elevator, as Figure 5 shown. According to the management regulations, the elevator must go through a regular inspection process, and the regular inspection creation screen (510) can be displayed on the maintenance terminal (500) to input inspection results during such a regular inspection process.

[0097] In the regular inspection creation screen (510), a caution warning confirmation button (520) for confirming the judgment results of failure caution and failure warning status can be formed. When a touch operation on the caution warning confirmation button (520) is performed, action control can be carried out to display the caution warning display screen (530). The caution warning display screen (530) can be displayed overlappingly on the regular inspection creation screen (510) as shown in Figure 6 , but alternatively, it can also be displayed separately in the form of screen transition.

[0098] In one embodiment, in the regular inspection creation screen (510), the elevator number (lift number), address, inspection period, inspection item, inspection content, etc. can be displayed.

[0099] In the caution warning display screen (530), a plurality of inspection item display areas (532) for displaying the failure caution and failure warning status of each inspection item can be formed. In each inspection item display area (532), information such as the code, judgment result (classification), diagnosis location (monitoring panel, inverter, etc.), occurrence count, occurrence count in the previous month, etc. regarding each inspection item can be displayed. Additionally, a detection period display area (531) can be formed to display information about the detection period for judging the corresponding failure caution and failure warning status.

[0100] In such a caution warning display screen (530), an evaluation input section (540) can be formed for maintenance staff to input evaluation opinions on the judgment results of the failure caution and failure warning status displayed for each inspection item of the elevator. The evaluation input section (540) can form the inspection item display areas (532) respectively. When a touch operation is performed on each inspection item display area (532), detailed information (detection conditions, code description, purpose, occurrence start time, etc.) corresponding to the respective inspection item display areas (532) can be displayed, and at the same time, the evaluation input section (540) regarding the judgment result of the corresponding inspection item can be displayed. The caution warning display screen (530) can include a details button (545). Clicking the details button (545) can show the associated detailed information - for example, expected causes (rated load abnormality, increased mechanical interference, occurrence of error, parameter error, etc.).

[0101] The evaluation input section (540) is used to input the evaluation opinions of maintenance staff, such as Figure 6As shown, it can be formed into a button form that can be input by touch operation. For example, when agreeing to the judgment result of the central management server (400), it can be formed into the form of a "consistent" button for touch operation, and when disagreeing to the judgment result of the central management server (400), it can be formed into the form of a "non-consistent" button for touch operation. Additionally, for example, the evaluation input unit (540) can be formed in a way that inputs whether a failure has occurred and whether the actual on-site state is a caution state or a warning state.

[0102] As described above, by forming the caution warning confirmation button (520) on the regular inspection creation screen (520), it is possible to guide the maintenance staff to confirm the failure caution and failure warning states of the corresponding elevator through the caution warning confirmation button (520) during the regular inspection. At this time, when the judgment result of the central management server (400) is a failure caution or a failure warning state, the caution warning confirmation button (520) displays a lamp with a different color compared to the normal state in a form with different recognition capabilities, enabling the maintenance staff to more easily recognize the failure caution or failure warning state.

[0103] In addition, the caution warning display screen (530) can be displayed on the regular inspection creation screen (510). Therefore, the maintenance staff can confirm the failure caution and failure warning states of the elevator during the regular inspection. In particular, the maintenance staff can directly conduct on-site inspections of the inspection items in the failure caution or failure warning state to confirm whether there are signs of failure. Through such a confirmation process, it is possible to evaluate whether the judgment results of the failure caution and failure warning states of the central management server (400) are appropriate or inappropriate. Based on whether they agree with the judgment results, the maintenance staff can input evaluation opinions through the evaluation input unit (540) formed by the "consistent / inconsistent" buttons as described above.

[0104] As described above, the judgment criteria of the central management server (400) for the failure caution and failure warning states can be newly updated based on the evaluation opinions input by the maintenance staff, and by repeating such a process, the judgment results of the central management server (400) for the failure caution and failure warning states can be made more accurate. That is, when there are many "inconsistent" opinions in the evaluation opinions of the maintenance staff, the central management server (400) can newly change the first judgment criterion and the second judgment criterion and obtain a new judgment result. If the "inconsistent" opinions in the evaluation opinions for the new judgment result decrease and the "consistent" opinions increase, it can mean that the accuracy of the evaluation results of the central management server (400) has improved. Therefore, by reflecting these evaluation opinions of the maintenance staff and newly adjusting the judgment criteria, the accuracy of the judgment results for the failure caution and failure warning states can be improved.

[0105] As described above, during the process of inputting the evaluation opinions on the fault attention and fault warning status after the regular inspection by the maintenance staff, the Figure 6 displayed attention warning display screen (530) can be used. Although not shown, before going to the site for regular inspection, the maintenance staff can also display a separate attention warning display screen (not shown) on the maintenance terminal. Before going to the site for elevator inspection, the maintenance staff can confirm the fault attention and fault warning status of the attention warning display screen (530) displayed on the maintenance terminal to identify the problem occurrence frequency, site characteristics, etc. of the corresponding site.

[0106] The reason for forming a "disagreement" button in the evaluation input unit (540) in addition to the "agreement" button is to filter out the information where the judgment result of the fault attention and fault warning status is inconsistent with the actual site conditions. If there is only the "agreement" button, it may be difficult for the maintenance staff to confirm the information when the information before going out is inconsistent with the information after going out.

[0107] Figure 7 is a block diagram showing an example of an elevator maintenance management system according to an embodiment of the present disclosure. Figure 8 is a block diagram showing an example of an elevator maintenance management system according to an embodiment of the present disclosure. Refer to Figure 7 and Figure 8 , the elevator maintenance management system includes an elevator side (800) component, a central management server (400) side component, and a service side component. Figure 7 The elevator side (800) of Figure 8 is of the monitoring panel type for managing multiple elevators,

[0108] Refer to Figure 7 , the elevator side (800) includes multiple elevators (810a, 810b, 801c). Each elevator (810a, 810b, 801c) is connected to a corresponding control panel (820a, 820b, 820c). Each control panel (820a, 820b, 820c) is connected to a terminal (830). The terminal (830) is managed by a monitoring panel program (840). In one embodiment, the terminal (830) and the monitoring panel program (840) can be referred to as a monitoring panel.

[0109] The central management server (400) includes an attention / warning code management unit (450) and a server management unit (460). The service side includes a maintenance terminal (500), a customer portal (600), and a remote management system (700).

[0110] Hereinafter, the hierarchy of the elevator side is defined as the upper layer in the order of elevator (810a, 810b, 801c) - control panel (820a, 820b, 820c) - terminal (830) - monitoring panel program (840). In addition, the attention / warning code management unit (450) of the central management server (400) that receives the code sent by the monitoring panel program (840) is defined as the upper layer of the monitoring panel program (840).

[0111] In one embodiment, each mechanical component, electronic component (e.g., motor, door, inverter, door inverter, etc.), control panel (820a, 820b, 820c), and terminal (830) included in the elevator (810a, 810b, 810c) can generate a code (W / A code) representing an abnormal signal (which may be included in the above-mentioned operation status signal) and send it to the component in the upper layer. At this time, the W / A code can be transmitted in real time or sent at a certain period. When the W / A code is transmitted at a certain period, the occurrence count and occurrence time can be sent simultaneously. That is, each mechanical component and electronic component included in the elevator (810a, 810b, 810c) can send the W / A code to the corresponding control panel (820a, 820b, 820c), the control panel (820a, 820b, 820c) can send the W / A code to the terminal (830), the terminal (830) can send the W / A code to the monitoring panel program (840), and the monitoring panel program (840) can send the W / A code to the attention / warning code management unit (450) of the central management server (400). The component in the upper layer (e.g., control panel (820a, 820b, 820c)) can relay the W / A code received from the component in the lower layer (e.g., elevator (810a, 810b, 810c)) to the component in the even higher layer (e.g., terminal (830)). Therefore, the attention / warning code management unit (450) can collect the W / A codes from each elevator (810a, 810b, 810c), control panel (820a, 820b, 820c), terminal (830), and monitoring panel program (840). Each component of the elevator side (800) can be configured to store the judgment criteria for generating each W / A code.

[0112] In addition, various operation status signals, including the speed, floor number, door operation status, button operation status, status of the OperatePanel Board (OPB), sensing signals of various sensors, etc., of the above elevator can be transmitted to the central management server (400) through the control panels (820a, 820b, 820c), the terminal (830), and the monitoring panel program (840). The central management server (400) can generate a W / A code based on the various operation status signals collected. The central management server (400) can generate a W / A code (e.g., a code starting with 5) with the central management server (400) as the diagnosis subject based on a preselected criterion, such as the duration of a specific condition, the number of occurrences, etc.

[0113] The W / A code and its corresponding description can be referred to in Table 1 below.

[0114] [Table 1]

[0115]

[0116] The codes shown in Table 1 are exemplary and can be set by the user to classify desired information. In one embodiment, the W / A code can include a code configured to represent the diagnosis subject and a code representing the diagnosis content (which can include problems, causes, etc.). The diagnosis subject can be the generation subject that generates the W / A code. For example, taking the W / A code 20016 in the first row of Table 1 as an example, 2 is the inverter as the diagnosis subject, and 16 is the code indicating a problem with the landing distance. More specifically, when the corresponding attention condition occurs in the inverter, a signal can be sent to the control panel through a preset bit in the inverter-control panel communication protocol. The attention condition (e.g., the criterion for abnormal signals) can be preselected or set and changed by the administrator. For example, the inverter as an elevator component can generate a W / A code based on a preselected criterion. The W / A code can be sensed in the terminal and sent to the central management server. More specifically, when an abnormal condition of the inverter is sensed, a W / A code is generated, and the W / A code can be stored in a specific memory in the control panel (electrically) connected to the information. The terminal uses the change value of the code value to sense whether a W / A code is generated, and when it senses the generation, it transmits the value to the server.

[0117] In one embodiment, the codes for the inverter as the detection subject can include codes associated with speed deviation, torque current, motor voltage, direct current (DC) link, initial value, inverter torque analysis in the constant speed range, landing distance, elevator car load, inverter torque, door speed deviation, door overload current, door encoder, door current offset, door communication status, etc.

[0118] In one embodiment, as will be described below, attention signals and warning signals can be generated based on the W / A code and a preselected reference. In contrast, as shown in Table 1, the W / A code can include information on attention signals and warning signals from the beginning. For example, both 20016 and 21011 are W / A codes generated by the inverter, and both have the same detection subject (here, the inverter). The difference between 20XXX and 21XXX refers to the same detection subject, i.e., the inverter, but it can be represented as 20 in the case of an attention signal and 21 in the case of a warning signal. That is, even for the same diagnostic subject, depending on the degree of abnormality of the operating state, a W / A code corresponding to a warning can be generated immediately. The degree, reference, etc. of these W / A codes can be preselected.

[0119] As another example, taking the W / A code 30001 in the second row of Table 1 as an example, the terminal confirms the inverter torque current feedback signal (hereinafter referred to as current Fbk) in the interval where the elevator is moving at a constant speed. When the time that the current Fbk exceeds 100% is longer than a predetermined time (e.g., 100 ms), the terminal generates 30001 and sends it to the server. The reference for generating and sending these W / A codes can be preselected and can be set and changed by the administrator.

[0120] In one embodiment, the code of the terminal as the diagnostic subject can include a code related to the communication state.

[0121] As another example, taking the W / A code 50150 in the fifth row of Table 1 as an example, the central management server (400) can generate the W / A code 50150 based on the action state signal. More specifically, the central management server (400) receives, through the control panel (820a, 820b, 820c), the terminal (830), and the monitoring panel program (840), one of the signals representing the action state, i.e., the landing button state abnormal signal (e.g., 150), and the central management server (400) can generate the W / A code 50150 corresponding to the cumulative amount of the landing button state abnormal signal reaching more than a predetermined number of times. In one embodiment, the signal representing the action state can be configured not to represent the generation subject or the diagnostic subject. That is, the signal representing the action state includes the landing button state abnormal signal, the door error signal, the communication state abnormal signal, etc., and can be configured to only represent the abnormal state of the components constituting the elevator.

[0122] In one embodiment, the code of the central management server (400) as the diagnostic subject can include codes related to the communication state with the OPB board, brake-related information, door errors, landing buttons, landing devices, rope elongation, multi-beam sensor-related information, etc.

[0123] For example, comparing 2XXXX with 5XXXX is described as follows. Corresponding to the driving of the inverter beyond a preset reference such as overloading operation of the inverter, an abnormality of the inverter is sensed and a WA code corresponding to 2XXXX is generated. The generated W / A code is sensed and stored by the control panel. The control panel transmits the 2XXXX W / A code to the central management server through the terminal.

[0124] 5XXXX is a W / A code generated by the central management server. For example, for 50150, the central management server can continuously receive the operation status of the elevator numbered 150 (e.g., landing call button problem), and based on a preselected reference, the central management server determines it to be in an attention state or a warning state (even if temporarily normalized), and the central management server can generate a W / A code of 50150.

[0125] In one embodiment, the control panel can be configured to store the W / A codes and abnormal operation status generated from elevator drive components such as inverters. The terminal can be configured to sense the information stored in the control panel and transmit it to the central management server.

[0126] As described above, the central management server (400) can store the W / A codes transmitted from the lower layer, and generate and store W / A codes based on the operation status signals.

[0127] Similarly, the terminal (830) and the monitoring panel program (840) can also generate W / A codes based on the received operation status signals according to preselected judgment references and send them to the upper layer.

[0128] This disclosure may include cases where the main body (diagnostic main body) generating the W / A code is the same as the diagnostic object and cases where the diagnostic main body is different from the diagnostic object.

[0129] The above W / A codes 20016 and 30001 are codes formed by combining the codes representing the diagnostic main body and the problem. Different from this, the codes representing the diagnostic main body and the codes representing the problem can also be generated and sent separately. That is, this disclosure includes the following: the constitution of the elevator side (800) sends codes (or their equivalents) formed in a manner representing the diagnostic main body and the problem to the constitution of the upper layer. Here, the problem can be formed in a manner representing at least one of the code content, cause, and code description.

[0130] In one embodiment, when the diagnostic main body sends a W / A code, it can simultaneously send the location (e.g., address, unit information). When the diagnostic main body sends a W / A code, it can simultaneously send at least any one of the occurrence times and occurrence times.

[0131] Refer to Figure 8, the elevator party (800) includes an elevator (810). The elevator (810) is connected to a control panel (820). The control panel (820) is connected to a terminal (830). The terminal (830) is connected to the attention / warning code management unit (450) of the central management server (400), and sends the W / A codes from the components of the elevator (810), the control panel (820), and the terminal (830) to the attention / warning code management unit (450). Figure 8 The control panel (820) and the terminal (830) respectively correspond to Figure 7 the control panels (820a, 820b, 820c) and the terminal (830) shown.

[0132] In one embodiment, the attention / warning code management unit (450) includes a W / A code collection unit (452) and a W / A code database (454). The W / A code collection unit (452) is configured to receive W / A codes from the elevator party (800). Various protocols can be used. As an example, the W / A code collection unit (452) receives W / A codes from the elevator party (800) in the JavaScript Object Notation (JSON) format. In one embodiment, the W / A code collection unit (452) may include an API.

[0133] The W / A code database (454) is configured to store the collected W / A codes. The W / A code database (454) is configured to store the W / A codes generated in the central management server (400). The W / A code database (454) can store information for interpreting the W / A codes. For example, the information for interpreting the W / A codes can store information about the elements constituting the W / A codes, such as information indicating which diagnostic subject and what problem. The W / A code database (454) can store the W / A codes, and the diagnostic subjects, diagnostic objects, locations, problems, problem causes, occurrence times, occurrence frequencies, etc. related to the W / A codes. The W / A code database (454) can store the W / A codes and the detection conditions, problems, problem causes, confirmation items, registration / modification times, etc. associated with the corresponding W / A codes. The W / A code database (454) can include attention / warning judgment criteria including threshold values, threshold frequencies, and time ranges. The W / A code database (454) can match and store the W / A codes, the addresses related to the W / A codes, building names or numbers, unit numbers, occurrence times, and diagnostic objects. The W / A code database (454) can store information to allow the creation of the table in Table 1. The W / A code database (454) can store the project number, site name, building and unit number (B / D and Line), W / A code, starting time, and detection object, and store information to allow the creation of the table as shown in Table 2 below. Although not shown, the occurrence time can include hours, minutes, and seconds.

[0134] [Table 2]

[0135]

[0136] In one embodiment, the W / A code database (454) can perform the functions of the above-mentioned action signal storage unit (402). In one embodiment, the server management unit (460) can include a fault processing unit (462) and a judgment unit (464). The fault processing unit (462) is configured to receive a fault code (which can correspond to the above-mentioned fault signal) from the elevator side (800). The fault processing unit (462) can collect and sense the fault code from the elevator side (800) in real time. The fault processing unit (462) is configured to analyze the fault code and generate a new fault code.

[0137] In one embodiment, the judgment unit (464) can receive the W / A code and identify which diagnostic subject and problem the W / A code represents. In addition, the judgment unit (464) can receive the W / A code and identify the cause of occurrence corresponding to the W / A code. The judgment unit (464) can generate a W / A code based on the action status signal.

[0138] In one embodiment, the determination unit (464) may execute the functions of the above-mentioned attention warning determination unit (404).

[0139] In one embodiment, the determination unit (464) may be configured to generate a new code based on the W / A code stored in the W / A code database (454) and the determination criteria, or generate at least one of an attention signal, a warning signal, and a failure signal. The determination unit (464) may send the generated attention signal, warning signal, and failure signal to at least any one of the maintenance terminal (500), the customer portal (600), and the remote management system (700). In one embodiment, the attention signal, warning signal, and failure signal may include a signal for setting the state of the elevator inspection items.

[0140] The determination criteria may include at least one of a critical number of times and a time range. In one embodiment, the determination criteria for the attention signal may include at least one of the attention signal critical number of times and the attention signal time range. The determination criteria for the warning signal may include at least one of the warning signal critical number of times and the warning signal time range. The determination criteria for the failure signal may include at least one of the failure signal critical number of times and the failure signal time range. The determination criteria may be set by an administrator.

[0141] For example, when the occurrence frequency of a specific W / A code is equal to or greater than the attention signal critical number of times and less than the warning signal critical number of times, the determination unit (464) may generate an attention signal and match it with the corresponding W / A code. When the occurrence frequency of a specific W / A code is equal to or greater than the warning signal critical number of times and less than the failure signal critical number of times, the determination unit (464) may generate a warning signal and match it with the corresponding W / A code. When the occurrence frequency of a specific W / A code is equal to or greater than the failure signal critical number of times, the determination unit (464) may generate a failure signal and match it with the corresponding W / A code. That is, since the corresponding W / A code has occurred a certain number of times, the current state being an attention state, a warning state, or a failure state can be notified to at least any one of the maintenance terminal (500), the customer portal (600), and the remote management system (700).

[0142] In addition, if within a preset time range (attention signal time range), the occurrence count of a specific W / A code is above the attention signal threshold count and less than the warning signal threshold count, the determination unit (464) may generate an attention signal. If within a preset time range (warning signal time range), the occurrence count of a specific W / A code is above the warning signal threshold count and less than the failure signal threshold count, the determination unit (464) may generate a warning signal. When within a preset time range (failure signal time range), the occurrence count of a specific W / A code is above the failure signal threshold count, the determination unit (464) may generate a failure signal. The preset time ranges (attention signal time range, warning signal time range, failure signal time range), such as 1 week, 2 weeks, 3 weeks, 4 weeks, 1 month, etc., can be set by the administrator.

[0143] In one embodiment, the judgment criteria for generating at least any one of the attention signal, warning signal, and failure signal may include comparing the occurrence count in a first preselected interval with the occurrence count in a second preselected interval. For example, comparing the occurrence count of a specific W / A code on a certain day in the interval from January 1st to January 31st with the occurrence count of the same specific W / A code in the interval from December 1st to December 31st, the determination unit (464) may generate at least any one of the attention signal, warning signal, and failure signal. Here, the interval from January 1st to January 31st is the first preselected interval, and the interval from December 1st to December 31st is the second preselected interval.

[0144] The comparison of the occurrence count in the first preselected interval with the occurrence count in the second preselected interval can be set by the administrator. For example, the determination unit (464) may generate an attention signal corresponding to a judgment that the occurrence count in the first preselected interval is 150% of the occurrence count in the second preselected interval, a warning signal corresponding to a judgment of 200%, and a failure signal corresponding to a judgment of 250%. That is, assuming that a specific W / A code occurred 30 times in the second preselected interval (e.g., from December 1st to December 31st), the determination unit (464) may generate an attention signal corresponding to the occurrence of 45 times of the specific W / A code on January 15th (any date), a warning signal corresponding to the occurrence of 60 times of the specific W / A code on January 20th (any date), and a failure signal corresponding to the occurrence of 75 times of the specific W / A code on January 28th (any date).

[0145] In one embodiment, the ratio of the number of occurrences in the first preselected interval to the number of occurrences in the second preselected interval may also be the ratio as described above, or may be an arithmetically determined value. For example, whenever the number of occurrences in the first preselected interval increases by 10 times compared to the number of occurrences in the second preselected interval, the determination unit (464) may sequentially generate a notice signal, a warning signal, and a failure signal.

[0146] It should be understood that the ratio or arithmetic value may be set by an administrator, and the determination criterion may be determined in other ways.

[0147] In one embodiment, the determination unit (464) may be configured to generate and notify a notice signal according to a predetermined number of times, and then generate and notify a warning signal. For example, the determination unit (464) may be configured to notify a warning signal once after notifying a notice signal three times.

[0155] In one embodiment, the central management server (400) can be implemented by a processor, a memory, and a communication unit. The processor can be an application specific integrated circuit (ASIC), a digital signal processor (DSP), a digital signal processing device (DSPD), a programmable logic device (PLD), a field programmable gate array (FPGA), a controller, a microcontroller, a microprocessor, or any form of processor or controller for performing other functions. The communication unit can be configured for the central management server (400) to communicate with other devices, such as an elevator party (800), a maintenance terminal (500), a customer portal website (600), and a remote management system (700), etc. The communication unit can be a hardware module such as a data bus, a network interface card, a network interface chip, and a network interface port for transmitting / receiving data and / or information, or a software module such as a network device driver or a network program. The memory can store multiple application programs or applications, data and commands that can be read by the processor. For example, the storage device can include various storage spaces such as a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a read only memory (ROM), a random access memory (RAM), an erasable programmable read only memory (EPROM), a flash drive, a hard disk drive, and cloud using a network, etc.

[0156] Figure 12It is a flowchart of steps for a central management server of an elevator maintenance management system to learn according to an embodiment of the present disclosure. Figure 12 The method can be executed in the central management server (400). It should be understood that Figure 12 the method can be executed in a conventional computing device.

[0157] The learning of the present disclosure can be executed using an artificial intelligence model. That is, the central management server (400) can include an artificial intelligence model. The artificial intelligence model can refer to a model that learns a learning model including an Artificial Neural Network (ANN) through a large amount of learning data in the present disclosure, optimizes the parameters inside the artificial neural network, and participates in the action of a system (not shown) using the learned learning model. In one embodiment, an artificial intelligence module (not shown) can learn through Machine Reading Comprehension (MRC). In one embodiment, the artificial neural network model for the artificial intelligence module has at least any one or a combination of a Convolutional Neural Network (CNN), a Deep Neural Network (DNN), a Recurent Neural Network (RNN), a Restricted Boltzmann Machine (RBM), a Deep Belief Network (DBN), a Bidirectional Recurrent Deep Neural Network (BRDNN), a Variational Auto Encoder (VAE), or a Deep Q-Networks, etc., but is not limited to the foregoing examples. The learning method can include: Rule-based Reasoning that generates a service by inferring data that meets specific rules among input data based on rules defined by a user, Case-based Reasoning that matches consistent / similar cases based on past cases to solve the problem of the current case, etc. In addition, inference techniques using supervised learning, unsupervised learning, reinforcement learning, neural networks, etc. can be utilized, but are not limited thereto.

[0158] In step S905, an abnormal signal is defined in or through the central management server (400). The abnormal signal may mean a signal that occurs when the action of the corresponding component exceeds the normal range but is not in a complete failure state. The abnormal signal may include the above-mentioned W / A code. The definition of the abnormal signal can be changed or set by the administrator. In the case where it is not necessary to change the definition of the determined abnormal signal, step S905 can be omitted.

[0159] In step S905, the central management server (400) collects abnormal signals. In one embodiment, the central management server (400) collects W / A codes. The central management server (400) can collect W / A codes, the addresses where W / A codes occur, elevator numbers, occurrence times, etc.

[0160] In step S915, the judgment criteria are changed. The judgment criteria include the criteria for the central management server (400) to generate attention signals, warning signals, and fault signals based on the occurrence times of W / A codes, the time range of occurrence, etc. The change of the judgment criteria can be executed by the administrator. Alternatively, the central management server (400) can change the judgment criteria. Since learning can be performed without changing the judgment criteria, step S915 can be omitted. In one embodiment, the judgment criteria can be the judgment criteria referred to Figure 7 and Figure 8 described. If the judgment criteria are changed in step S915, the status set in step S920 will change, so more learning data can be ensured.

[0161] In step S920, the central management server (400) sets an attention state and a warning state based on the judgment criteria. In one embodiment, the central management server (400) can set a normal operation state, a fault state, and an abnormal state where there is no fault but maintenance is required. The abnormal state can include an attention state and a warning state. For example, the W / A code, the occurrence times, the occurrence interval, and the attention / warning / normal / fault state can be matched.

[0162] In step S925, the central management server (400) receives the actual status of the components included in the elevator party (800). In one embodiment, the actual status can include a normal operation state, a fault state, and an abnormal state where there is no fault but maintenance is required. Additionally, the abnormal state can include an attention state and a warning state.

[0163] In step S930, the central management server (400) matches the set status with the actual status received in step S925 based on the judgment criteria set in step S920, and uses it as learning data to train the artificial intelligence model. In one embodiment, the learning data can include W / A codes and associated information, the status according to the judgment criteria, and the actual status.

[0164] In step S930, the artificial intelligence model reflects the learning result.

[0165] Figure 13 It is a flowchart showing the process of judging the attention and warning states of an elevator maintenance management system according to an action flow according to an embodiment of the present disclosure.

[0166] In step S1300, elevator components, such as inverters, traction motors, main ropes, door drive motors, etc., generate action status signals and first W / A codes. In one embodiment, the elevator components may perform actions outside a fixed range corresponding to the actions of the elevator components to generate action status signals. For example, there may be cases where the actions of elevator components are judged to have unstable communication states when performing actions outside a fixed range, cases where the time for pressing a landing button is judged to be longer than a specified time, cases of door errors, cases where the inverter torque deviates from the fixed range, etc.

[0167] In one embodiment, the elevator component includes an inverter, and the inverter may include a controller. The controller included in the inverter can confirm the action state of the inverter and generate a W / A code according to a preset standard.

[0168] In step S1305, the control panel senses and stores the action status signal and the first W / A code. For example, the control panel may be configured to sense and store the first W / A code generated in the inverter. In order to sense the working states of the components constituting the elevator, sensors may be installed on each component (traction motor, main rope, door drive motor, etc.).

[0169] In step S1310, the control panel generates a second W / A code. The control panel sends the action status signal, the first W / A code, and the second W / A code to the terminal. The control panel can sense the actions of the elevator components and generate an action status signal corresponding to the judgment of performing actions outside a fixed standard. The control panel can generate an action status signal based on the action states of the control panel components. The control panel can send the first W / A code and the action status signal received from the elevator components, the second W / A code generated by the control panel, and the action status signal to the terminal.

[0170] For example, in order to sense the action states of the components constituting the elevator, sensors may be installed on each component (such as traction motors, main ropes, door drive motors, etc.). The control panel can confirm the action states of the elevator components through the sensors, generate and store a second W / A code according to a preset standard, and can send the second W / A code to a higher-level entity, such as a terminal. In one example, the control panel may include a controller and a memory. The control panel may be configured to generate, store, and send a second W / A code according to the control of the controller.

[0171] In step S1315, the terminal generates a third W / A code and sends the action status signal, the first W / A code to the third W / A code to the central management server. The terminal can generate the third W / A code based on the action status signal received from the control panel. For example, the inverter torque current value is received within the rated operating range of the elevator, and the third W / A code can be generated based on this. The terminal can generate the action status signal based on the action status of the terminal components. The terminal can send the first W / A code, the second W / A code, and the action status signal received from the control panel, the third W / A code generated by the terminal, and the action status signal to the central management server.

[0172] In step S1320, the central management server stores the received action status signal and the first W / A code to the third W / A code.

[0173] In step S1325, the central management server generates and stores a fourth W / A code based on the received action status signal. For example, when it is determined that the time for which the landing button is pressed is longer than the specified time, the fourth W / A code can be generated corresponding to the number of times the generated action management signal is greater than the predetermined number of times.

[0174] In step S1330, the central management server determines the attention status or warning status based on the first W / A code and the fourth W / A code. The central management server can further determine the normal status or failure status based on the first W / A code and the fourth W / A code. The judgment criteria for the attention status or warning status are as described above.

[0175] In one embodiment, the W / A code can be configured to include only the problem without indicating the diagnostic subject.

[0176] In the present disclosure, the inverter can include an inverter for controlling the speed and torque of the elevator and an inverter for controlling the door.

[0177] In the present disclosure, the elevator drive components can include a traction machine, a traction rope, a drive sheave, a gearless motor, a power regeneration device, a brake, a rope brake, an overspeed regulator, an anti-pinch device, a multi-beam, a door safety device, a door suspension, etc.

[0178] In the present disclosure, when a component malfunctions, the load, torque abnormality, current abnormality, etc. can be sensed in the connected inverter to generate a W / A code associated with the abnormal operation of the corresponding component. For example, the inverter can sense an abnormality in the traction machine.

[0179] In the present disclosure, the control panel can monitor the abnormal operation of the components. For example, the control panel can sense the voltage application amount, control signal omission, etc. of the control panel and generate an associated W / A code.

[0180] In the present disclosure, the storage capacity of the terminal may be greater than that of the control panel. The terminal can monitor the data stored in the memory of the control panel and generate a W / A code based on the accumulated data.

[0181] The method according to the present disclosure can be implemented as a processor-readable code on a processor-readable recording medium included in a server, system, device, computer, integrated control device, etc. used by a certain entity.

The processing device can execute an operating system (OS) and one or more software applications executed on the operating system. In addition, the processing device can respond to the execution of software and access, store, operate, process, and generate data. For ease of understanding, it is sometimes described as using one processing device, but for those skilled in the relevant technical field, it is understood that the processing device may include multiple processing elements and / or multiple types of processing elements. For example, the processing device may include multiple processors or one processor and one controller. In addition, other processing configurations such as a parallel processor can also be achieved.

[0183] Software may include a computer program, code, instruction, or a combination of more than one of them, and may constitute a processing device, or independently or collectively command a processing device to operate as desired. In order to interpret or provide commands or data to a processing device, software and / or data may be permanently or temporarily embodied in any type of machine, component, physical device, virtual equipment, computer storage medium or device, or transmitted signal wave. Software is distributed in computer systems connected to a network, and thus may also be stored or implemented in a distributed manner. Software and data may be stored in more than one computer-readable recording medium.

[0184] The embodiments described in this disclosure may also be implemented in a distributed computing environment where certain tasks are performed by remote processing devices connected through a communication network. In a distributed computing environment, program modules may be located in both local memory storage devices and remote memory storage devices.
