Description

Technical Field

[0001] The present invention relates to a maintenance system for a passenger transfer device.

Background Art

[0002] Generally, various types of high-rise buildings constructed for residential, business, commercial, etc. purposes are equipped with elevator devices for the smooth floor movement of passengers entering and leaving the corresponding buildings.

[0003] An elevator device includes an elevator car that moves passengers while moving vertically in a hoistway formed inside a building with passengers on board, a motor unit that generates predetermined power, a hoisting machine, etc., a mechanical unit that moves the elevator car to the corresponding floor by the button operation of passengers, and an elevator control unit that controls the mechanical unit by the button operation of passengers and performs control so that the elevator car can operate smoothly and stably.

[0004] Although such an elevator device cannot avoid the occurrence of failures during use, how quickly repair work is carried out when a failure occurs is a very important factor in elevator maintenance.

[0005] Generally, when a failure report occurs in an elevator device, a repair worker is dispatched to connect a serial cable, etc. to the control panel in the machine room to check the error code generated, the repair worker analyzes the corresponding error code to grasp the cause of the failure, and then performs repair work.

[0006] In this case, since the error code will be checked and analyzed after the repair worker is dispatched to the site, the cause of the failure cannot be grasped in advance.

[0007] In addition, there is a problem that it is difficult to prepare necessary parts, equipment, etc. according to the cause of the failure during the process of dispatching to the site. Therefore, after dispatching to the site and confirming the site, the parts and equipment necessary for the repair work must be prepared afterwards. This not only worsens the setup for the repair work, but also causes problems such as the repair work taking a long time.

[0008] In addition, when an elevator fails, a considerable number of error codes are generated in a short time. Therefore, it is difficult for the repair worker to grasp the exact cause of the failure based on such error codes. Especially in the case of novice repair workers, there is a problem that it becomes extremely difficult to find the main cause of the failure based on multiple error codes.

[0026] The error code information displayed on the repair terminal can include at least one of an error code name, an error code occurrence time, and information on the operating state of the passenger transfer device at the time when the error code occurs.

[0027] The present invention provides a maintenance system for a passenger transfer device, including a failure diagnosis server that collects and stores error code information of the passenger transfer device from a passenger transfer device control panel, and diagnoses a failure cause based on the collected error code information; and a repair terminal connected to the failure diagnosis server, to which the error code information stored in the failure diagnosis server and the diagnosis result for the failure cause are transferred and displayed. The failure diagnosis server classifies a plurality of sequentially generated error code information into one time-series data group at preset reference time intervals, and diagnoses the failure cause by analyzing the corresponding error code information for each time-series data group.

[0034] Also, when the failure diagnosis server receives an information request input signal for the failure diagnosis result from the repair terminal, the diagnosis unit can diagnose the cause of the failure for the error code information of the corresponding time-series data group and transfer the diagnosis result to the repair terminal.

[0035] Further, the diagnosis unit can diagnose the cause of the failure for the error code information of the corresponding time-series data group and derive at least one or more causes of the failure and the occurrence probability information for each cause of the failure together as a diagnosis result.

[0036] On the one hand, the present invention is a control method for a passenger transfer device maintenance system including a fault diagnosis server and a repair terminal. The method includes the steps of: the fault diagnosis server collecting and storing error code information of the passenger transfer device from the passenger transfer device control panel; the fault diagnosis server diagnosing the cause of the fault based on the collected error code information; and the repair terminal being connected to the fault diagnosis server and the error code information stored in the fault diagnosis server and the diagnosis result for the cause of the fault being transferred and displayed. The fault diagnosis server classifies a plurality of error code information generated in sequence into one time-series data group for each preset reference time interval, and diagnoses the cause of the fault by analyzing the corresponding error code information for each time-series data group. A control method for a maintenance system of a passenger transfer device is provided, which is characterized by the above.

[0037] The present invention includes a fault diagnosis server that collects and stores error code information of a passenger transfer device from a passenger transfer device control panel and diagnoses the cause of the fault based on the collected error code information; and a repair terminal connected to the fault diagnosis server, to which the error code information stored in the fault diagnosis server and the diagnosis result for the cause of the fault are transferred and displayed. The repair terminal is configured such that a repair operator can select some of the plurality of error code information displayed on the repair terminal, and can request the fault diagnosis server for the fault diagnosis result for the selected error code information. The fault diagnosis server analyzes the error code information selected by the repair terminal according to the information request signal of the repair terminal, diagnoses the cause of the fault, and transfers the fault diagnosis result to the repair terminal.

[0040] In addition, the display unit includes a first output screen having an error code display area where the error code information is displayed in a state classified by the time series data group. On the first output screen, there can be formed a selection mode conversion button for converting the error code information displayed in the error code display area into a selection screen mode that allows a repair worker to select, and a diagnosis result request input button that can request the failure diagnosis result for the error code information selected in the selection screen mode from the failure diagnosis server.

[0041] In addition, the display unit includes a selection diagnosis output screen on which error code information selected by a repair worker and a failure diagnosis result for the selected error code information are displayed. When an input signal is generated by the diagnosis result request input button, the control unit transfers an information request signal for requesting a failure diagnosis result for the selected error code information to the failure diagnosis server. When the failure diagnosis result is received from the failure diagnosis server according to the information request signal, the control can be operated so that the error code information and the failure diagnosis result are displayed on the selection diagnosis output screen.

[0044] According to the present invention, when a failure occurs in a passenger conveyance device, a repair worker can check error code information in advance before going to the site, and can prepare necessary parts and equipment, thereby improving the maintenance efficiency of the passenger conveyance device.

[0045] According to the present invention, since information on the cause of a failure is provided to the repair terminal device, the repair worker can check the information on the cause of the failure not only at the failure site but also outside the failure site.

[0046] In addition, since the repair worker can prepare in advance the parts and equipment that can handle the failure cause information before going to the site, the setup and repair time of the repair work can be improved.

[0047] In addition, even a novice repair worker can easily determine the failure state and handle the failure.

[0048] According to the present invention, since failure cause diagnosis can be performed based on some of the error code information selected by the repair worker using the repair terminal device, various types of failure diagnosis results can be obtained from a plurality of error codes.

Mode for Carrying Out the Invention

[0058] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, when adding reference numerals to the components of each drawing, it should be noted that for the same components, as much as possible, the same numerals are used even if they are shown on different drawings. Further, in describing the present invention, when it is determined that a specific description of a related known configuration or function may change the gist of the present invention, the detailed description thereof will be omitted.

[0059] First, the passenger conveyance device according to the present invention includes an elevator, an escalator, and a moving walkway. Hereinafter, the description will be based on an elevator.

[0060] FIG. 1 is a drawing conceptually showing the overall configuration of an elevator maintenance system according to an embodiment of the present invention, and FIG. 2 is a drawing conceptually showing the overall configuration of an elevator maintenance system according to another embodiment of the present invention.

[0061] An elevator maintenance system according to an embodiment of the present invention includes a failure diagnosis server 500 that collects error code information from an elevator control panel 100 to diagnose the cause of a failure, and a repair terminal 600 that is connected to the failure diagnosis server 500 and to which error code information and a failure diagnosis result are transferred and displayed.

[0062] First, looking at the overall system configuration, the elevator may include a control panel 100 that controls the operating state of the elevator. The control panel 100 can receive signals for the operating state information of the elevator. The control panel can receive various failure occurrence signals. The operating state information and failure occurrence signals of the elevator may be generated by a number of sensors provided in the elevator. The control panel 100 can receive the operating state information and failure occurrence signals of the elevator through such sensors. Such a control panel 100 can receive and store signals related to the operating state and failures of the elevator. When a failure occurrence signal is generated, the control panel 100 can generate an error code that matches the failure occurrence signal.

[0063] The operation status signal and error code information can be transferred to the central management server 400 in real time through the communication unit 200. As shown in FIG. 1, in the communication unit 200, communication with the central management server 400 can be performed through the modem 310, and the operation status signal and error code information can be transferred. As shown in FIG. 2, 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 transfer the corresponding information.

[0064] The central management server 400 can transfer the received corresponding information to a separate fault diagnosis server 500. The fault diagnosis server 500 can receive the operation status signal and error code information. The fault diagnosis server 500 can be applied as a cloud server and can be connected to the repair terminal 600 through the Internet network. The elevator operation status information and error code information received by the fault diagnosis server 500 can be transferred to the repair terminal 600. In the repair terminal 600, the user can connect to the fault diagnosis server 500 through the application program and receive the elevator operation status information and error code information. Also, the fault diagnosis server 500 can analyze the received error code information to analyze the cause of the fault. The fault diagnosis server 500 can derive the diagnosis result of the cause of the fault. The fault diagnosis result derived in this way can be provided to the repair terminal 600 through the application program of the repair terminal 600.

[0065] When a fault signal occurs in the elevator or a fault report is received, a repair worker can be selected according to the maintenance system. The selected repair worker can be provided with the basic information about the corresponding elevator. The basic information about the elevator provided to the repair worker may include the fault reporting situation or the basic specifications of the elevator, etc.

[0066] In the elevator maintenance system according to an embodiment of the present invention, error codes, diagnosis results of faults, etc. can be transferred to the repair terminal device through the fault diagnosis server 500. The repair operator can prepare the necessary parts and equipment before going out. Thereby, the fault handling time can be shortened, and the fault handling operation becomes easier.

[0067] Hereinafter, the detailed configuration of the elevator maintenance system according to an embodiment of the present invention will be described in more detail.

[0068] FIG. 3 is a block diagram functionally showing the configuration of the fault diagnosis server and the repair terminal device of the elevator maintenance system according to an embodiment of the present invention, FIGS. 4 and 5 are diagrams exemplarily showing the connection method of the repair terminal device to the fault diagnosis server and the display method of the fault diagnosis result in the elevator maintenance system according to an embodiment of the present invention, and FIG. 6 is a diagram exemplarily showing the form of the error code information displayed on the repair terminal device according to an embodiment of the present invention.

[0069] As described above, the elevator maintenance system according to an embodiment of the present invention can include a fault diagnosis server 500 and a repair terminal device 600.

[0070] The fault diagnosis server 500 can collect and store the error code information of the elevator from the elevator control panel 100, and can diagnose the cause of the fault based on the collected error code information. The repair terminal device 600 can be connected to the fault diagnosis server 500, and the error code information stored in the fault diagnosis server 500 and the diagnosis result for the cause of the fault can be transferred and displayed.

[0071] The fault diagnosis server 500 can include a first communication unit 501a, an error code storage unit 502, a diagnosis unit 503, and a second communication unit 501b.

[0072] The first communication unit 501a receives in real time the error code information recorded in the elevator control panel 100. As described above, the error code information recorded in the elevator control panel 100 is transferred to the central management server 400, and the first communication unit 501a can communicate with the central management server 400 and receive the error code information from the central management server 400. In addition to the error code information recorded in the elevator control panel 100, the first communication unit 501a can also receive the operating state information of the elevator. For example, the first communication unit 501a can receive general elevator operating state information such as the speed of the elevator, the floor number, the operating state of the door, and the sensing signals of various sensors. In particular, the first communication unit 501a can receive various information such as the operating state change information of the elevator at the time when the error code occurs.

[0073] The error code storage unit 502 can store the error code information and the elevator operating state information received through the first communication unit 501a. The diagnosis unit 503 can analyze the error code information stored in the error code storage unit 502 to diagnose the cause of the failure. The diagnosis unit 503 can diagnose the cause of the failure when an information request signal is received from the repair terminal 600.

[0074] The second communication unit 501b can communicate with the repair terminal 600 and receive the information request signal of the repair terminal 600. The second communication unit 501b can transfer the error code information stored in the error code storage unit 502 and the failure diagnosis result derived by the diagnosis unit 503 to the repair terminal 600. The second communication unit 501b can also transfer various information such as the elevator operating state information stored in the error code storage unit 502 to the repair terminal 600.

[0075] The fault diagnosis server 500 can collect the error codes and elevator operation status information recorded in the elevator control panel 100 through the first communication unit 501a and store them in the error code storage unit 502. When the fault diagnosis server 500 receives an information request signal from the repair terminal 600, the fault diagnosis server 500 can diagnose the cause of the fault for the error code through the diagnosis unit 503. In addition, the fault diagnosis server 500 can transfer error code information, fault diagnosis results, elevator operation status information, etc. to the repair terminal 600.

[0076] The repair terminal 600 can mean a wireless communication-capable terminal carried by a repair worker. The repair terminal 600 can include an input unit 603, a display unit 602, a terminal communication unit 601, and a control unit 604.

[0077] The input unit 603 can be formed on the repair terminal 600 so that a repair worker can perform an input operation. The input unit 603 can be formed in various forms such as a touch operation method through a touch panel on the repair terminal 600 or separate physical buttons.

[0078] The display unit 602 can display error code information, fault diagnosis results, elevator operation status information, etc. transferred from the fault diagnosis server 500. The display unit 602 can be formed on a display screen formed on the repair terminal 600.

[0079] The terminal communication unit 601 communicates with the second communication unit 501b of the fault diagnosis server 500, and can transfer an information request signal, etc. to the fault diagnosis server 500, and receive error code information, fault diagnosis results, and elevator operation status information, etc. from the fault diagnosis server 500.

[0080] The control unit 604 can control the operations of the input unit 603, the display unit 602, and the terminal communication unit 601 of the repair terminal 600. When a repair operator generates an input signal through the input unit 603, the control unit 604 can control its operation to transfer an information request signal corresponding to the input signal to the fault diagnosis server 500 through the terminal communication unit 601. In accordance with the transfer of such an information request signal, error code information, fault diagnosis results, elevator operating status information, etc. can be received from the fault diagnosis server 500 through the terminal communication unit 601. The control unit 604 can control its operation so that the error code information, fault diagnosis results, elevator operating status information, etc. received from the fault diagnosis server 500 are displayed on the display unit 602.

[0081] When a fault signal of the elevator occurs, a repair operator can be selected, and basic information about the corresponding elevator can be provided to the selected repair operator through the repair terminal 600. In an embodiment of the present invention, error code information and fault diagnosis results can be additionally transferred to the repair terminal 600 through the fault diagnosis server 500.

[0082] At this time, in an embodiment of the present invention, as shown in FIG. 4, a confirmation request notification message requesting the repair operator to confirm the fault diagnosis result can be transferred to the repair terminal 600 of the repair operator. The confirmation request notification message may include the web link address CL of the fault diagnosis server where the fault diagnosis result can be confirmed. As shown in FIG. 4, the confirmation request notification message can be transferred to the repair operator's mobile phone or repair terminal by the SMS transfer method.

[0083] When a repair operator touches the web link address CL included in the confirmation request notification message in the SMS method, a connection input signal for the web link address CL can be generated. The control unit 604 can transfer an information request signal corresponding to the web link address CL to the failure diagnosis server 500 according to such a connection input signal. The control unit 604 can control the operation so that the error code information and the failure diagnosis result received from the failure diagnosis server 500 are displayed on the display unit 602 according to the transfer of the information request signal.

[0084] That is, by touching the web link address CL of the confirmation request notification message transferred to the repair terminal 600 by the repair operator, it is possible to connect to the failure diagnosis server 500 and check the error code, the failure diagnosis result, and the like.

[0085] On the other hand, as shown in FIG. 5, it can be configured so that a repair operator connects to a failure diagnosis server through a separate repair management program provided in the repair terminal. For example, a connection button CB may be formed in the repair management program of the repair terminal. When a repair operator touches the connection button CB, a connection input signal for the failure diagnosis server 500 can be generated. The control unit 604 transfers an information request signal corresponding to the connection button CB to the failure diagnosis server 500 according to such a connection input signal, and controls the operation so that the error code information and the failure diagnosis result received from the failure diagnosis server 500 are displayed on the display unit 602 according to the transfer of the information request signal.

[0086] That is, by touching the connection button CB formed in the repair management program of the repair terminal 600 by the repair operator, it is possible to connect to the failure diagnosis server 500 and check the error code, the failure diagnosis result, and the like. At this time, as shown in FIG. 5, the connection button CB can be formed in a button form on which a message such as "Failure diagnosis connection" is displayed.

[0087] When checking the past failure handling results in the repair management program, if you want to check with reference to the failure information such as the past error code information for the corresponding elevator, you can check the past error code information and the failure diagnosis result through the connection button CB. That is, in the repair management program, the repair operator can touch the connection button CB at any time according to the need to check the error code information and the failure diagnosis result for the corresponding elevator. Through this, the accuracy of the repair work can be improved, and it can also be used as reference information for new employees for repair work.

[0088] To summarize, when a failure occurs in the elevator, the basic information for the corresponding elevator is transferred to the repair terminal of the selected repair operator, and at the same time, a confirmation request notification for the error code and the failure diagnosis result of the corresponding elevator can be transferred. This can be done in the short message method. When a connection input signal is generated through the link address CL included in the short message or the connection button CB of the repair management program, an information request signal is transferred to the failure diagnosis server 500, and the error code and the failure diagnosis result can be received from the failure diagnosis server 500 and displayed on the display unit 602 of the repair terminal 600.

[0089] Therefore, before the repair operator goes to the failure site, they can check the error code and the failure diagnosis result of the corresponding elevator, so they can prepare the necessary parts and equipment in advance and go to the site.

[0090] On the other hand, the error code storage unit 502 of the failure diagnosis server 500 can sort and store the error code information received through the first communication unit 501a in chronological order. The error code storage unit 502 can classify and store the error code information into one time-series data group at preset reference time intervals. The diagnosis unit 503 can analyze the corresponding error code information for each time-series data group stored in the error code storage unit 502 to diagnose the cause of the failure for the time-series data group.

[0091] In addition, as shown in FIGS. 4 and 5, on the display unit 602 of the repair terminal 600, a first output screen 610 can be formed that has an error code display area 611 where error code information is displayed and a diagnosis result display area 612 where a fault diagnosis result is displayed. In the error code display area 611, at least one or more error codes are displayed arranged in chronological order, and can be classified and displayed for each one time series data group classified by the fault diagnosis server 500. That is, it can be formed such that one time series data group is displayed in one error code display area 611. At this time, one diagnosis result display area 612 can be formed to correspond to each one error code display area 611 so that the fault diagnosis result is displayed for each one time series data group.

[0092] In addition, as shown in FIG. 6, each error code information displayed in the error code display area 611 includes an error code name EN, an error code occurrence time ET, and elevator operation state information ED at the time when the error code occurred. In addition to this, activation information EA of the corresponding error code can also be displayed together.

[0093] For example, the error code name EN represents the type of error code and can be displayed like "ER_HUP_BTN_JAM", and the error code occurrence time ET can be displayed in the lower area thereof. Also, the elevator operation state information ED at the time when the corresponding error code occurred can display the floor number, current speed / maximum speed (illustrated as the 3rd floor, current speed 0 / maximum speed 120 in FIG. 6), etc. Also, the activation information EA of the error code represents whether the corresponding error code is currently activated or in an inactivated state. As shown in FIG. 6, when it is displayed as "OFF", it can be understood that the corresponding error code is currently inactivated.

[0094] With such a structure, when a repair worker connects to the fault diagnosis server 500 through the repair terminal 600, error code information and fault diagnosis information for the corresponding elevator will be displayed on the screen of the repair terminal 600. At this time, the error code information includes the error code name, occurrence time, and operating status information of the elevator, etc. Therefore, in addition to the fault diagnosis results provided by the fault diagnosis server 500, the repair worker can also check the basic operating status information of the elevator and can also infer the fault diagnosis results by himself through the relevant error code information.

[0095] That is, in one embodiment of the present invention, by connecting to the fault diagnosis server 500 through the repair terminal 600, the repair worker can check all the error codes generated in the corresponding elevator, so that the situation at the scene can be predicted and judged in advance before going to the scene.

[0096] In this way, in addition to the fault diagnosis results, the error codes and the operating status information of the elevator are provided through the repair terminal 600. In the case of veteran repair workers, they can judge the fault causes different from the fault diagnosis results provided by the fault diagnosis server 500 by themselves, so more accurate prediction and on-site response may be possible. Also, in the case of novice repair workers, they can smoothly carry out on-site response with reference to the fault diagnosis results provided by the fault diagnosis server 500.

[0097] Also, a large number of error codes occur in the time before and after the time of fault occurrence. However, the fault diagnosis server 500 can receive the error code information detected by the elevator control panel 100 in real time. Since all the error code information and the operating status information of the elevator generated in the time before and after the time of fault occurrence can be collected, more accurate fault diagnosis results can be derived.

[0098] Furthermore, error codes that occur in sequence at very short time intervals are separately classified in time-series group units based on the reference time unit, and by diagnosing the cause of the failure in time-series group units, a more rapid and accurate diagnosis result can be derived. The reference time can be set by the error code storage unit 502 of the failure diagnosis server 500.

[0099] For example, the error code storage unit 502 of the failure diagnosis server 500 can set the reference time to 5 minutes and classify and store a plurality of error codes in one time-series data group at 5-minute intervals. When a failure occurs in the elevator, error code information is continuously generated before and after the time of failure, and this can be classified into one time-series data group at 5-minute intervals. In this way, the cause of the failure is diagnosed and provided for each time-series data group. Therefore, error code information that occurs at very short time intervals of several seconds per unit at the time of failure can be quickly classified and analyzed, and through this, a failure diagnosis result can be quickly derived, so that the processing speed and accuracy of the repair work can be improved.

[0100] On the other hand, the failure diagnosis server 500 can be provided with a failure diagnosis program that can analyze error code information and diagnose the cause of the failure. The failure diagnosis program can be configured in a manner that diagnoses the cause of the failure based on information pre-input by veteran technicians.

[0101] Therefore, the failure diagnosis server 500 can include a cause-of-failure storage unit 504 that matches and stores a plurality of pre-specified reference error code information and at least one or more causes of failure corresponding to the reference error code information respectively.

[0102] The diagnosis unit 503 can diagnose the cause of the failure for the error code information based on the data stored in the cause-of-failure storage unit 504. For example, the diagnosis unit 503 can learn the mutually matched error code information and at least one or more causes of failure as learning data, and diagnose the cause of the failure for the error code in a machine learning method.

[0103] In addition, when the repair process work at the repair work site is completed, the repair worker can input the failure processing result. At this time, the input failure processing result can be transferred to the failure diagnosis server 500 through the central management server 400. The failure diagnosis server 500 can change the information stored in the failure cause storage unit 504 by reflecting the information on the failure processing result of such a repair worker.

[0104] Therefore, the failure diagnosis server 500 can include a failure cause update unit 505 that reflects the information on the failure processing result input by the repair worker and newly matches the failure cause for the reference error code information stored in the failure cause storage unit 504.

[0105] Due to the failure cause update unit 505, the information on the error code and the failure cause stored in the failure cause storage unit 504 is newly changed, and the accuracy of the information on the error code and the failure cause can be increased as the data volume of the failure processing result increases. Therefore, the elevator maintenance system according to an embodiment of the present invention can improve the accuracy and reliability of the failure diagnosis result of the failure diagnosis server 500 as the usage period elapses.

[0106] On the other hand, when an error occurs in the communication state among the elevator control panel 100, the central management server 400, and the failure diagnosis server 500 for a certain period of time, the error code information stored in the elevator control panel 100 may not be transferred to the failure diagnosis server 500 during the error occurrence time. In this case, since all the error code information is not transferred to the failure diagnosis server 500, the failure diagnosis result obtained by diagnosing the failure cause based on the error code information in the failure diagnosis server 500 may have a reduced accuracy. To prepare for this, a manual collection button can be formed on the first output screen 610 of the repair terminal 600. When the repair worker touches the manual collection button, the error code information and the like can be collected again from the elevator control panel 100 to the failure diagnosis server 500 for a certain period of time.

[0107] FIG. 7 is a diagram exemplarily showing a method of displaying a fault diagnosis result on a repair terminal according to an embodiment of the present invention.

[0108] As described above, in the elevator maintenance system according to an embodiment of the present invention, when an information request signal is transferred from the repair terminal 600 to the fault diagnosis server 500 according to a connection input signal, an error code and a fault diagnosis result can be transferred from the fault diagnosis server 500 to the repair terminal 600 for each time-series data group and displayed.

[0109] However, when a connection input signal is generated from the repair terminal 600, an information request signal for the error code is transferred to the fault diagnosis server 500, and as shown in FIG. 7, a plurality of error code information can be transferred from the fault diagnosis server 500 to the repair terminal 600 for each time-series data group and displayed. When an information request signal for requesting a fault diagnosis result is transferred through the repair terminal 600, the diagnosis unit 503 of the fault diagnosis server 500 can diagnose the cause of the error for each error code in each time-series data group. The fault diagnosis server 500 can transfer and display the corresponding fault diagnosis result to the repair terminal 600.

[0110] That is, the fault diagnosis result for the error code of one time-series data group is not immediately provided by connecting to the fault diagnosis server 500, but when the repair operator requests the corresponding diagnosis result, the fault diagnosis server 500 diagnoses the cause of the fault through the fault diagnosis program and can be configured to provide the fault diagnosis result to the repair terminal.

[0111] To explain more specifically, when a repair operator touches the link address CL transferred by short message to the repair terminal 600 or touches the connection button CB of the repair management program to generate a connection input signal, the control unit 604 of the repair terminal 600 can control its operation to transfer an information request signal for error code information to the fault diagnosis server 500. When receiving such an information request signal, the fault diagnosis server 500 transfers the error codes stored in the error code storage unit 502 to the repair terminal 600 by time-series data group, and the control unit 604 of the repair terminal 600 can control its operation so that the transferred error codes by time-series data group are displayed on the display unit 602.

[0112] At this time, as shown in Fig. 7(a), the control unit 604 of the repair terminal 600 can control its operation so that a diagnosis result request input button 613 capable of inputting an information request signal for the fault diagnosis result is formed in the diagnosis result display area 612 in a state where the error code information is classified and displayed by time-series data group in the error code display area 611. As described above, since the diagnosis result display area 612 is formed one by one in the error code display area 611 separated by each time-series data group and the diagnosis result request input button 613 is formed in the diagnosis result display area 612, the diagnosis result request input buttons 613 can be formed one by one for each time-series data group.

[0113] In the state thus displayed, when a repair worker touches the diagnostic result request input button 613 of any one time-series data group, an input signal for requesting a failure diagnosis result may be generated. When such an input signal is generated, the control unit 604 of the repair terminal 600 can control its operation to transfer an information request signal for requesting a failure diagnosis result for the error code information of the corresponding time-series data group corresponding to the diagnostic result request input button 613 to the failure diagnosis server 500. The failure diagnosis server 500 diagnoses the cause of failure for the error code of the corresponding time-series data group through the diagnosis unit 503 according to such an information request signal and derives a diagnosis result. The derived failure diagnosis result can be transferred from the failure diagnosis server 500 to the repair terminal 600. The control unit 604 of the repair terminal 600 can control its operation so that the failure diagnosis result of the transferred time-series data group is displayed in the diagnostic result display area 612 of the corresponding time-series data group on the first output screen 610. At the same time, it can control its operation to remove the diagnostic result request input button 613 displayed in the diagnostic result display area 612. That is, when the failure diagnosis result is transferred to the repair terminal 600, as shown in Fig. 7(b), in the diagnostic result display area 612, the diagnostic result request input button 613 is removed and at the same time the failure diagnosis result can be displayed.

[0114] As shown in Fig. 7, the diagnostic result request input button 613 formed in the diagnostic result display area 612 can be formed so as to be touch-operable in a form in which a message of "Call" is displayed.

[0115] With such a structure, the failure diagnosis server 500 can diagnose the cause of failure for a specific time-series data group only when a failure diagnosis result request signal is transferred from the repair terminal 600. Therefore, it is not necessary to repeatedly diagnose the cause of failure for all past error codes, and it is not necessary to separately store the failure diagnosis results for all past error codes, so that the overload of the failure diagnosis server 500 can be prevented and the capacity can be miniaturized.

[0116] On the other hand, in the process of diagnosing the cause of a failure for the error code information of one time-series data group, the diagnosis unit 503 of the failure diagnosis server 500 can derive at least one or more failure causes and the occurrence probability information for each failure cause together as a diagnosis result. The failure causes and the occurrence probability information derived in this way can be displayed together in the diagnosis result display area 612 of the repair terminal 600.

[0117] For example, as shown in FIG. 7(b), firstly, the failure diagnosis result for the time-series data group is displayed as "The upper button at the landing is pinched (100%)". This means that the cause of the failure is that the upper button at the landing is pinched, and the corresponding failure probability is 100%. Secondly, the failure diagnosis result for the time-series data group can be displayed as "Door motor failure (75%), Door pinched (25%)". This can mean that the probability that the cause of the failure is a door motor failure is 75%, and the probability that the door is pinched is 25%.

[0118] By displaying the probability information for the cause of the failure together in this way, the repair operator can determine the work order considering the corresponding probability information in the process of failure handling, and the repair work can be carried out more quickly and accurately.

[0119] On the other hand, when the failure cause and / or the occurrence probability information displayed in the result display area 612 is selected, a repair guide corresponding to the failure cause is displayed. The repair guide may include the parts and / or repair methods that can repair the displayed failure.

[0120] FIG. 8 is a drawing exemplarily showing a screen for displaying a failure diagnosis result for the error code information selected by a user in an elevator maintenance system according to an embodiment of the present invention.

[0121] As described above, the elevator maintenance system according to an embodiment of the present invention can classify several error code information into one time-series data group at each reference time interval and provide a failure diagnosis result based on the error code information for each individual time-series data group. In addition, as shown in FIG. 8, a repair operator can select some of the plurality of error code information, separately analyze the selected error code information, and provide a failure diagnosis result based on the corresponding error code information to the repair terminal 600.

[0122] As described above, the display unit 602 of the repair terminal can include a first output screen 610 having an error code display area 611 and a diagnosis result display area 612. As shown in FIG. 8, a selection mode conversion button 631 can be formed on the first output screen 610 so that the error code information displayed in the error code display area 611 can be converted into a selection screen mode in which a repair operator can select it. When the repair operator touches the selection mode conversion button 631, it can be converted into a selection screen mode in which some of the error code information displayed in the error code display area 611 can be selected. The first output screen 610 illustrated in FIG. 8(a) exemplarily shows a state converted into the selection screen mode. In such a selection screen mode state, a repair operator can touch and select a plurality of error code information. In FIG. 8(a), a state in which three error code information are selected is exemplarily illustrated.

[0123] In addition, a selection diagnosis result request input button 632 is formed on the first output screen 610, which can request the failure diagnosis server 500 for a failure diagnosis result for the error code information selected in the selection screen mode.

[0124] At this time, the selection mode conversion button 631 and the selection diagnosis result request input button 632 may be automatically generated simultaneously when the first output screen 610 is displayed on the display unit 602. However, different from this, as shown in FIG. 8(a), by touching the setting button 630 automatically generated on the first output screen 610, the selection mode conversion button 631 and the selection diagnosis result request input button 632 can be configured to be generated on the first output screen 610.

[0125] After the repair operator touches the selection mode conversion button 631 to convert the first output screen 610 to the selection screen mode state, some error code information can be selected. When the selection of the error code information is completed, the repair operator can touch the selection diagnosis result request input button 632. When an input signal is generated by touching the selection diagnosis result request input button 632, the control unit 604 can control its operation to transfer an information request signal for requesting a failure diagnosis result for the selected error code information to the failure diagnosis server 500. Then, the diagnosis unit 503 of the failure diagnosis server 500 can analyze the cause of the failure for the selected error code information and derive the failure diagnosis result together with the probability information. Then, the derived failure diagnosis result can be transferred to the repair terminal 600.

[0126] On the repair terminal 600, a selection diagnosis output screen 620 that can display the error code information selected by the repair operator and the failure diagnosis result for the selected error code information can be formed. The control unit 604 can control its operation so that the failure diagnosis result transferred from the failure diagnosis server 500 to the repair terminal 600 is displayed on the selection diagnosis output screen 620 together with the selected error code information. At this time, the selection diagnosis output screen 620 can be displayed so as to overlap the first output screen 610 as shown in FIG. 8(b). On the selection diagnosis output screen 620, a selection error code display area 621 for displaying the selected error code information and a selection diagnosis result display area 622 for displaying the failure diagnosis result for the same can be formed in a form similar to the first output screen 610.

[0127] On the other hand, there is no particular limitation on the range in which the repair worker can select the error code information. That is, it is possible to select a part of the error code information within one and the same time-series data group, or it is also possible to select one or more pieces of error code information respectively in different time-series data groups. In FIG. 8, a state in which two pieces of error code information are selected in one time-series data group and one piece of error code information is selected in another time-series data group is illustratively shown.

[0128] In this way, by separately performing a failure diagnosis on the error code information separately selected by the user through the failure diagnosis server, in addition to the failure diagnosis result for the error code information of the time-series data group, it is possible to obtain failure diagnosis results for more diverse error code information according to the user's selection. In particular, through such selection of error code information, it is possible to separately diagnose the cause of failure for error code information in a specific time period, for example, the time when the passenger was trapped. Through this, the efficiency of the repair work can be further improved.

[0129] The above description merely illustratively explains the technical idea of the present invention, and those having ordinary knowledge in the technical field to which the present invention pertains can make various modifications and variations without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are for the purpose of explanation rather than for limiting the technical idea of the present invention, and the scope of the technical idea of the present invention is not limited by such embodiments. The protection scope of the present invention must be interpreted according to the following claims, and all technical ideas within the equivalent scope must be interpreted as being included in the scope of rights of the present invention.
