Description

Technical Field

[0001] The present invention relates to a repair terminal for inputting a failure processing result by a selection method of a repair worker and a passenger transfer device maintenance system using the same, and further relates to a passenger transfer device maintenance system with improved input accuracy of a failure processing result.

Background Art

[0002] Generally, various types of high-rise buildings constructed for residential, business, commercial, etc. purposes are equipped with elevator devices for smooth floor-to-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 a predetermined power, a hoisting machine, etc., a mechanical unit that moves the elevator car to the corresponding floor by a passenger's button operation, and an elevator control unit that controls the mechanical unit by a passenger's button operation and controls so that the elevator car can operate smoothly and stably.

[0004] Such an elevator device cannot avoid the occurrence of failures during use, but how quickly repair work is performed 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 that has occurred, the repair worker analyzes the corresponding error code to grasp the cause of the failure, and performs repair work.

[0006] When the repair work is completed, the repair worker inputs the fault handling result into the repair terminal. However, since such a process of inputting the fault handling result is carried out in a way that the repair worker directly creates and inputs it by handwriting, it is difficult to accurately input the entire process of fault handling. In particular, there are problems such as cases where part of the processing process of the fault handling work performed by the repair worker is omitted. In this case, it is difficult to perform accurate post-processing on the fault handling result, and there are problems such as hindering the utilization of fault handling data such as statistical creation.

[0041] 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 the same components should have the same numerals as much as possible 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.

[0042] 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.

[0043] FIG. 1 is a diagram conceptually showing the overall configuration of an elevator maintenance system according to an embodiment of the present invention, and FIG. 2 is a diagram conceptually showing the overall configuration of an elevator maintenance system according to another embodiment of the present invention.

[0044] 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.

[0045] 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 regarding 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 can 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 regarding 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.

[0046] The operating state 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 operating state 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.

[0047] The central management server 400 can transfer the received relevant information to a separate fault diagnosis server 500. The fault diagnosis server 500 can receive the operating state signal and error code information. The fault diagnosis server 500 can be applied as a cloud server and connected to the repair terminal 600 through the Internet network. The elevator operating state information and error code information received by the fault diagnosis server 500 can be transferred to the repair terminal 600. At the repair terminal 600, the user can connect to the fault diagnosis server 500 through the application program and receive the elevator operating state 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.

[0048] 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 of the elevator provided to the repair worker may include the fault reporting situation or the basic specifications of the elevator, etc.

[0049] In the elevator maintenance system according to an embodiment of the present invention, error codes, fault diagnosis results, etc. can be transferred to the repair terminal through the fault diagnosis server 500. The repair worker can prepare the necessary parts and equipment before going out. Thereby, the fault handling time can be shortened and the fault handling work becomes easier to perform.

[0050] Hereinafter, the detailed configuration of the elevator maintenance system according to an embodiment of the present invention will be described in more detail.

[0051] FIG. 3 is a block diagram functionally illustrating the configuration of a failure diagnosis server and a repair terminal of an elevator maintenance system according to an embodiment of the present invention. FIGS. 4 and 5 are diagrams exemplarily illustrating a failure diagnosis server connection method and a failure diagnosis result display method of a repair terminal in an elevator maintenance system according to an embodiment of the present invention. FIG. 6 is a diagram exemplarily illustrating a form of error code information displayed on a repair terminal according to an embodiment of the present invention.

[0052] As described above, an elevator maintenance system according to an embodiment of the present invention can include a failure diagnosis server 500 and a repair terminal 600.

[0053] The failure diagnosis server 500 can collect and store error code information of the elevator from the elevator control panel 100, and can diagnose the cause of the failure based on the collected error code information. The repair terminal 600 can be connected to the failure diagnosis server 500, and the error code information stored in the failure diagnosis server 500 and the diagnosis result for the cause of the failure can be transferred and displayed.

[0054] The failure 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.

[0055] 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 an error code occurs.

[0056] The error code storage unit 502 can store the error code information received through the first communication unit 501a and the operating state information of the elevator, etc. 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. When an information request signal is received from the repair terminal 600, the diagnosis unit 503 can diagnose the cause of the failure.

[0057] 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 operating state information of the elevator stored in the error code storage unit 502 to the repair terminal 600.

[0058] 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.

[0059] The repair terminal 600 may mean a wireless communication-enabled terminal carried by a repair worker. The repair terminal 600 may include an input unit 603, a display unit 602, a terminal communication unit 601, and a control unit 604.

[0060] 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.

[0061] 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.

[0062] 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, elevator operation status information, etc. from the fault diagnosis server 500.

[0063] 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.

[0064] When a fault signal of the elevator occurs, a repair operator is 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.

[0065] 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. The confirmation request notification message can be transferred to the repair operator's mobile phone or repair terminal in the SMS transfer method, as shown in FIG. 4.

[0066] By touching 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 fault diagnosis server 500 according to such a connection input signal. According to the transfer of the information request signal, the control unit 604 can control the operation so that the error code information and the fault diagnosis result received from the fault diagnosis server 500 are displayed on the display unit 602.

[0067] 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 fault diagnosis server 500 and check the error code, the fault diagnosis result, and the like.

[0068] On the other hand, as shown in FIG. 5, it can be configured so that the repair operator connects to the fault 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. By touching the connection button CB by the repair operator, a connection input signal for the fault diagnosis server 500 can be generated. The control unit 604 transfers an information request signal corresponding to the connection button CB to the fault diagnosis server 500 according to such a connection input signal, and according to the transfer of the information request signal, controls the operation so that the error code information and the fault diagnosis result received from the fault diagnosis server 500 are displayed on the display unit 602.

[0069] 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 fault diagnosis server 500 and check the error code, the fault diagnosis result, and the like. At this time, as shown in FIG. 5, the connection button CB can be formed in a button form with a message such as "Fault diagnosis connection" displayed.

[0070] 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 as needed 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.

[0071] In summary, 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 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 failure diagnosis result can be received from the failure diagnosis server 500 and displayed on the display unit 602 of the repair terminal 600.

[0072] Therefore, before the repair operator goes to the failure site, they can check the error code and failure diagnosis result of the corresponding elevator, so they can prepare the necessary parts and equipment in advance and go to the site.

[0073] On the other hand, the error code storage unit 502 of the failure diagnosis server 500 can arrange 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 it into one time series data group at each preset reference time interval. 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.

[0074] In addition, as shown in FIGS. 4 and 5, on the display unit 602 of the repair terminal 600, a first output screen 610 having 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 can be formed. In the error code display area 611, at least one or more error codes are displayed so as to be 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 so as to correspond to one error code display area 611 respectively, so that the fault diagnosis result is displayed for each one time series data group.

[0075] 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 point when the error code occurs. In addition, activation information EA of the corresponding error code can also be displayed together.

[0076] 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. In addition, the elevator operation state information ED at the time point when the corresponding error code occurs can display the floor number, the current speed / maximum speed (illustrated as the 3rd floor, current speed 0 / maximum speed 120 in FIG. 6), etc. In addition, the activation information EA of the error code represents whether the corresponding error code is currently activated or deactivated. As shown in FIG. 6, when it is displayed as "OFF", it can be seen that the corresponding error code is currently deactivated.

[0077] 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 are displayed on the screen of the repair terminal 600. At this time, since the error code information displays the error code name, the occurrence time, and the operating state information of the elevator, etc., in addition to the fault diagnosis results provided by the fault diagnosis server 500, the repair worker can check the basic operating state information of the elevator and can also infer the fault diagnosis results by himself through the relevant error code information.

[0078] That is, in one embodiment of the present invention, the repair worker can connect to the fault diagnosis server 500 through the repair terminal 600 to 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.

[0079] In this way, in addition to the fault diagnosis results, the error codes and the operating state information of the elevator are provided through the repair terminal 600. In the case of a veteran repair worker, he can judge the fault causes different from the fault diagnosis results provided by the fault diagnosis server 500 by himself, so that more accurate prediction and on-site response can be achieved. Also, in the case of a novice repair worker, on-site response can be carried out smoothly with reference to the fault diagnosis results provided by the fault diagnosis server 500.

[0080] Also, a large number of error codes occur in the time before and after the fault occurrence time, but 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 state information of the elevator generated in the time before and after the fault occurrence time can be collected, more accurate fault diagnosis results can be derived.

[0081] Furthermore, error codes that occur in sequence at very short time intervals are separately classified in time series group units based on a 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.

[0082] 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 into 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 at the time of failure can be quickly classified and analyzed, and through this, a failure diagnosis result can be quickly derived, improving the processing speed and accuracy of the repair work.

[0083] 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.

[0084] 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 each reference error code information.

[0085] 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 manner.

[0086] In addition, when the repair processing 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.

[0087] 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.

[0088] By 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] However, when a connection input signal is generated from the repair terminal 600, an information request signal for an 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 time-series data group with respect to the error code. The fault diagnosis server 500 can transfer and display the corresponding fault diagnosis result to the repair terminal 600.

[0093] 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.

[0094] 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 the 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 separately for each time series data group, and the control unit 604 of the repair terminal 600 can control the operation so that the error codes for each transferred time series data group are displayed on the display unit 602.

[0095] At this time, as shown in Fig. 7(a), the control unit 604 of the repair terminal 600 can control the 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 separately for each 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 for 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.

[0096] In the state thus displayed, when a repair worker touches the diagnosis result request input button 613 of any one time-series data group, an input signal for requesting a failure diagnosis result can be generated. When such an input signal is generated, the control unit 604 of the repair terminal 600 controls the 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 diagnosis result request input button 613 to the failure diagnosis server 500. The failure diagnosis server 500 diagnoses the cause of the failure for the error code of the corresponding time-series data group through the diagnosis unit 503 in accordance with 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 the operation so that the failure diagnosis result of the transferred time-series data group is displayed in the diagnosis result display area 612 of the corresponding time-series data group on the first output screen 610. At the same time, the operation can be controlled to remove the diagnosis result request input button 613 displayed in the diagnosis result display area 612. That is, when the failure diagnosis result is transferred to the repair terminal 600, as shown in FIG. 7(b), the diagnosis result request input button 613 is removed from the diagnosis result display area 612, and at the same time, the failure diagnosis result can be displayed.

[0097] As shown in FIG. 7, the diagnosis result request input button 613 formed in the diagnosis result display area 612 can be formed so as to be touch-operable in a form in which a message of "Call" is displayed.

[0098] With such a structure, the failure diagnosis server 500 can diagnose the cause of the 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 the failure for all past error codes, and it is not necessary to separately store the failure diagnosis results for all past error codes. Thus, the overload of the failure diagnosis server 500 can be prevented and the capacity can be miniaturized.

[0099] On the one hand, during 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 occurrence probability information derived in this way can be displayed together in the diagnosis result display area 612 of the repair terminal 600.

[0100] For example, as shown in FIG. 7(b), firstly, the failure diagnosis result for the first 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 second 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%.

[0101] By displaying the probability information for the cause of the failure together like this, the repair operator can determine the work order considering the corresponding probability information during the failure handling process, and can perform the repair work more quickly and accurately.

[0102] On the other hand, when the failure cause and / or 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.

[0103] The above described the process of diagnosing the cause of a failure for the error code through the failure diagnosis server 500 and displaying the diagnosis result on the repair terminal 600 when a failure occurs in the elevator, that is, the process before the failure handling. Through such a process before the failure handling, as described above, the failure handling work can be performed more quickly and efficiently. After the failure handling work is completed, the repair operator inputs the failure handling result into the repair terminal 600.

[0104] Hereinafter, with reference to FIGS. 8 to 11, the configuration of the repair terminal 600 that can input such a failure processing result accurately without input errors or omissions will be described.

[0105] FIG. 8 is a drawing exemplarily showing a basic information input screen on a processing result input screen of a repair terminal according to an embodiment of the present invention. FIG. 9 is a drawing exemplarily showing a component selection input screen in a selection input screen of a processing result input screen according to an embodiment of the present invention. FIG. 10 is a drawing exemplarily showing an additional selection input screen in a selection input screen of a processing result input screen according to an embodiment of the present invention. FIG. 11 is a drawing exemplarily showing an error code selection input screen in a selection input screen of a processing result input screen according to an embodiment of the present invention.

[0106] Referring to FIG. 8, a repair terminal 600 according to an embodiment of the present invention may include a processing result input screen 690 through which a repair operator can input a failure processing result after completion of a failure processing operation.

[0107] The processing result input screen 690 may include a basic information input screen 691 for inputting basic information of a failure processing operation and a plurality of selection input screens 692 for inputting a failure processing result in a manner of selecting through a plurality of selection buttons.

[0108] As shown in FIG. 8, a basic information input area 691a for inputting basic information regarding a failure processing operation may be formed on the basic information input screen 691. The basic information input area 691a can be formed so as to input various information related to the failure processing operation. For example, in the basic information input area 691a, a summary of the failure, detailed content, etc. can be handwritten. An auxiliary inspector can be selected through an auxiliary inspector selection menu. When the failure processing has not been completed, the reason for non-processing can be selected through a "reason for non-processing" menu formed in the basic information input area 691a.

[0109] On the basic information input screen 691, a completion button 691b for switching the screen to the selection input screen 692 described later can be formed. After the repair operator inputs the basic information through the basic information input area 691a and touches the completion button 691b, the selection input screen 692 can be displayed on the display screen of the repair terminal device.

[0110] Referring to FIGS. 9 to 11, information regarding the failure part of the elevator can be input on the selection input screen 692. A plurality of selection input screens 692 can be formed so as to be displayed in order according to the operation of the repair operator. On each selection input screen 692, a plurality of selection buttons for displaying failed parts, additional information regarding the failure, error codes, etc. can be formed. Such a selection input screen 692 can include a part selection input screen 693, an additional selection input screen 694, and an error code selection input screen 695.

[0111] The part selection input screen 693, the additional selection input screen 694, and the error code selection input screen 695 can be displayed in order according to the input operation of the repair operator. That is, when the selection operation for the selection buttons on the part selection input screen 693 is completed, the additional selection input screen 694 is displayed, and when the selection operation for the selection buttons on the additional selection input screen 694 is completed, finally the error code selection input screen 695 is displayed. The repair operator can complete the input operation of the failure processing result through the selection operation for the selection buttons on the error code selection input screen 695.

[0112] In this way, on each of the plurality of selection input screens 692: 693, 694, 695, a separate screen switching tap for screen switching can be formed in the upper area, and screen switching for the plurality of selection input screens can be performed in such a way that the repair operator touches the screen switching tap. Of course, different from the screen switching tap, a separate selection completion button (not shown) can be displayed on each selection input screen, and it can also be configured to be switched to the next-order selection input screen when the selection completion button is touched. The screen switching method can be set in various ways.

[0113] In this way, among the multiple selection buttons formed on each of the plurality of selection input screens 692:693, 694, 695 that are switched in sequence on the screen, since the failure processing result can be input by selecting a specific selection button, the handwriting input process is excluded in the process of inputting the failure processing result, and there is no input error or omission of the failure processing result, and the failure processing result can be accurately input. Even a novice repair operator can easily input the failure processing result without difficulty.

[0114] Hereinafter, the selection input screen 692 will be described more specifically.

[0115] First, the component selection input screen 693 can be formed so that the repair operator can select and input the failed component. In other words, on the component selection input screen 693, information regarding the failure location can be selected and input. The component selection input screen 693 is formed such that a plurality of failure-related selection buttons 6931, 6932, 6933 for respectively displaying the failure areas, failure locations, and failed components that can occur in the elevator can be selected by the repair operator.

[0116] Such a component selection input screen 693 can include, as shown in FIG. 9, a one-step selection input screen 693a, a two-step selection input screen 693b, and a three-step selection input screen 693c.

[0117] On the one-stage selection input screen 693a, a plurality of major classification selection buttons 6931 for classifying and displaying areas that may malfunction in the elevator at the first stage can be formed so as to be selectable by the repair worker. As shown in Fig. 9(a), the major classification selection button 6931 can be formed in a manner of displaying the corresponding position together with the visualization image of the elevator. Four major classification selection buttons 6931 can be formed on the major classification selection button 6931, which largely classify the areas where elevator failures may occur into four areas. For example, major classification selection buttons 6931 can be formed that classify the areas where elevator failures may occur into four major classifications: the machine room, the elevator car (cage), the hoistway / pit, and the landing (hall). The repair worker can make a primary selection of the failure area at the major classification stage by touching and selecting any one of such major classification selection buttons 6931. Of course, this is exemplary, and it is also possible to form the major classification selection buttons 6931 by classifying the areas where elevator failures may occur into various numbers such as three or five.

[0118] On the two-stage selection input screen 693b, a plurality of failure part selection buttons 6932 for displaying failure parts where failures may occur in the failure area corresponding to the major classification selection button 6931 selected through the one-stage selection input screen 693a can be formed so as to be selectable by the repair worker. For example, as shown in Fig. 9(b), when the major classification selection button 6931 for the machine room is selected on the one-stage selection input screen 693a, failure part selection buttons 6932 for displaying failure parts where failures may occur in the machine room, such as the control panel PCB, the inverter, and control panel parts, can be formed on the two-stage selection input screen 693b.

[0119] The three - stage selection input screen 693c can be formed such that a plurality of faulty component selection buttons 6933, which display the faulty components where a fault can occur at the faulty part corresponding to the fault part selection button 6932 selected through the two - stage selection input screen 693b, can be selected by the repair operator. For example, as shown in (c) of FIG. 9, when the fault part selection button 6932 for the control panel PCB is selected on the two - stage selection input screen 693b, on the three - stage selection input screen 693c, faulty component selection buttons 6933 can be formed that display the faulty components where a fault can occur in the control panel PCB, such as the main board (Main Bd), safety board (Safety Bd), power board (Power Bd), etc.

[0120] When the selection operation by the repair operator is completed on each of the one - stage selection input screen 693a, two - stage selection input screen 693b, and three - stage selection input screen 693c, the selection input screens of the next stage can be sequentially displayed.

[0121] For example, as described above, when the selection of the major - classification selection button 6931 for the machine room is completed on the one - stage selection input screen 693a, the two - stage selection input screen 693b is displayed on the display screen of the repair terminal. When the selection of the fault part selection button 6932 for the control panel PCB is completed on the two - stage selection input screen 693b, the three - stage selection input screen 693c is displayed on the display screen of the repair terminal. When the selection of any one or more, for example, the faulty component selection button 6933 for the main board is completed on the three - stage selection input screen 693c, the additional selection input screen 694 described later is displayed. At this time, on each selection input screen, as described above, a screen - switching tap or a separate selection - completion button can be formed, and screen switching can be performed through this.

[0122] When the selection input process for the component selection input screen 693 including such three selection input screens 693a, 693b, and 693c is completed, the additional selection input screen 694 can be displayed on the display screen of the repair terminal.

[0123] As shown in FIG. 10, the additional selection input screen 694 can be formed so that additional information regarding a failure can be selected and input. On the additional selection input screen 694, a plurality of additional selection buttons 6941, 6942, 6943 for displaying the cause of the failure, the subject of the failure, and the type of failure processing work can be formed so as to be selectable by the repair worker.

[0124] Such an additional selection input screen 694 may include a failure cause selection input screen 694a, a failure subject selection input screen 694b, and a processing work selection input screen 694c.

[0125] The failure cause selection input screen 694a can be formed so that a plurality of failure cause additional selection buttons 6941 for respectively displaying the causes of failure that can occur in the elevator are selectable by the repair worker. For example, as shown in FIG. 10(a), a plurality of failure cause additional selection buttons 6941 for respectively displaying types of failure causes such as component defect, installation defect, contact defect, etc. can be formed.

[0126] The failure subject selection input screen 694b can be formed so that a plurality of failure subject additional selection buttons 6942 for respectively displaying the subjects of failure for failures that can occur in the elevator are selectable by the repair worker. For example, as shown in FIG. 10(b), a plurality of failure subject additional selection buttons 6942 for respectively displaying types of failure subjects such as inspection items, user's fault, power outage, etc. can be formed.

[0127] The processing work selection input screen 694c is formed so that a plurality of processing work additional selection buttons 6943 for respectively displaying the types of failure processing work for failures that can occur in the elevator are selectable by the repair worker. For example, as shown in FIG. 10(c), a plurality of processing work additional selection buttons 6943 for respectively displaying types of failure processing work such as adjustment, replacement, removal, etc. can be formed.

[0128] The failure cause selection input screen 694a, the failure entity selection input screen 694b, and the processing operation selection input screen 694c can display the next-stage selection input screens in sequence when the selection operations by the repair operator are completed on their respective selection input screens.

[0129] For example, as described above, on the failure cause selection input screen 694a, if the selection of the failure cause addition selection button 6941 for component failure is completed, the failure entity selection input screen 694b can be displayed on the display screen of the repair terminal. If the selection of the failure entity addition selection button 6942 for inspection items is completed on the failure entity selection input screen 694b, the processing operation selection input screen 694c can be displayed on the display screen of the repair terminal. If the selection of the processing operation addition selection button 6943 for adjustment is completed on the processing operation selection input screen 694c, the error code selection input screen 695 described later is displayed. At this time, on each selection input screen, a screen switching tap or a separate selection completion button can be formed as described above, and screen switching can be performed through this. Also, on each addition selection input screen 694, one selection button or multiple selection buttons can be set to be selectable.

[0130] When the selection input process for the addition selection input screen 694 including such three selection input screens 694a, 694b, and 694c is completed, the error code selection input screen 695 can be displayed on the display screen of the repair terminal. Such an error code selection input screen 695 can be configured to be displayed after the selection input process of the addition selection input screen 694. However, since the addition selection input screen 694 is for inputting additional information for the failure, the addition selection input screen 694 can be omitted as needed, and the error code selection input screen 695 can also be configured to be displayed after the selection input process of the component selection input screen 693.

[0131] As shown in FIG. 11, the error code selection input screen 695 can be formed such that a plurality of error code selection buttons 6951 for respectively displaying error codes that may occur for the failed component selected through the component selection input screen 693 are selectable by the repair operator. For example, the repair operator can select the component selection button 6933 for the final failed component (main board) on the three-stage selection input screen 693c through the stages of the one-stage to three-stage selection input screens 693a, 693b, and 693c in the component selection input screen 693. At this time, on the error code selection input screen 695, a plurality of error code selection buttons 6951 for respectively displaying all the error codes that may occur for the selected failed component can be formed.

[0132] The repair operator can finally complete the input operation of the failure processing result by touching and selecting the error code selection button 6951 corresponding to the error code for which the repair operator has completed the failure processing among such a plurality of error code selection buttons 6951.

[0133] When a failure occurs in the elevator, since a plurality of error codes are generated, the repair operator can select a plurality of error code selection buttons 6951 on the error code selection input screen 695. FIG. 11 exemplarily shows a case where six error code selection buttons 6951 are selected. As shown in FIG. 11, the six selected error code selection buttons 6951 can be displayed in a different color or shape so as to be distinguishable from the unselected error code selection buttons 6951.

[0134] In addition, on the error code selection input screen 695, in the process where the repair operator touches and selects a plurality of error code selection buttons 6951, the corresponding order can be displayed in a one-side area of the error code selection button 6951 according to the selection order of the error code selection buttons 6951. Exemplarily, in FIG. 11, for such a selection order, the corresponding order can be displayed in the form of red round numbers in the upper right area of the error code selection button 6951.

[0135] In this way, when the repair operator inputs the failure processing result by selecting a plurality of selection buttons instead of handwriting on the repair terminal, the failure processing result can be input without input error or omission and accurately. Also, a novice repair operator can easily input the failure processing result.

[0136] On the other hand, since the failure processing result input to the repair terminal in such a manner has a high accuracy, it can be collected by the failure diagnosis server 500 described in FIGS. 1 to 7 and reflected in the failure cause diagnosis process of the failure diagnosis server 500.

[0137] As described above, the elevator maintenance system according to an embodiment of the present invention is such that the failure diagnosis server 500 can collect and store the error code information of the elevator from the elevator control panel 100. The failure diagnosis server 500 can diagnose the cause of failure based on the collected error code information. The error code information and the failure diagnosis result can be transferred to the repair terminal and displayed.

[0138] At this time, the failure diagnosis server 500 can collect the failure processing result input through the selection input screen 692 of the repair terminal 600. The failure diagnosis server 500 can diagnose the cause of failure by reflecting the failure processing result collected in the past in the process of diagnosing the cause of failure based on the error code information.

[0139] More specifically, the failure diagnosis server 500 may include, as described above, a failure cause storage unit 504 and a failure cause update unit 505 in order to improve the failure diagnosis accuracy of the diagnosis unit 503. The failure cause update unit 505 can newly match the cause of failure for the reference error code information stored in the failure cause storage unit 504 by reflecting the information on the failure processing result input by the repair operator.

[0140] Therefore, the higher the accuracy of the failure processing result input by the repair operator, the more the failure diagnosis accuracy of the diagnosis unit 503 can be improved.

[0141] In one embodiment of the present invention, since the failure processing result is input in a selection input manner through the selection input screen 692 of the repair terminal 600, the accuracy can be improved. Since such a highly accurate failure processing result is reflected in the failure cause storage unit 504 through the failure cause update unit 505, the failure diagnosis accuracy of the diagnosis unit 503 can be further improved. In particular, as the data amount of highly accurate failure processing results accumulates, the accuracy of information on error codes and failure causes can increase. Therefore, in the elevator maintenance system according to one embodiment of the present invention, the accuracy and reliability of the failure diagnosis results of the failure diagnosis server 500 continue to improve as the usage period elapses.

[0142] FIG. 12 is a drawing exemplarily showing a highlighted display form of a predicted error code selection button in an error code selection input screen according to one embodiment of the present invention.

[0143] As described above, on the error code selection input screen 695 according to one embodiment of the present invention, a plurality of error code selection buttons 6951 that can be selected and input by the repair worker can be formed. At this time, in order to guide the repair worker's error code selection input operation, the error code selection button 6952 corresponding to the error code predicted as the failure cause can be displayed so as to be distinguishable from the other error code selection buttons 6951.

[0144] To explain more specifically, as described above, the failure diagnosis server 500 can diagnose the cause of a failure based on the error code information collected from the elevator control panel 100, and extract the error code corresponding to the cause of the failure calculated through the diagnosis result. The error code generated by one cause of failure can be one or more. Therefore, the failure diagnosis server 500 can extract one or more error codes corresponding to the cause of failure predicted through the failure cause diagnosis. Also, the cause of failure predicted by the failure diagnosis server 500 can be multiple as described above. In this case, a plurality of error codes corresponding to each cause of failure can be extracted. The process of diagnosing the cause of failure by the failure diagnosis server 500 can be performed in the manner of applying the data stored in the failure cause storage unit 504 to the machine learning model as described above.

[0145] By such a method, the failure diagnosis server 500 can extract the error code predicted as the cause of failure. The repair terminal 600 can receive the error code information predicted as such a cause of failure from the failure diagnosis server 500. The control unit 604 of the repair terminal 600 can display the error code selection button 6952 corresponding to the error code predicted as the cause of failure on the error code selection input screen 695 (hereinafter referred to as the predicted error code selection button) so as to be distinguishable from other error code selection buttons 6951.

[0146] Such a predicted error code selection button 6952 can be displayed so as to have a different color or form from other error code selection buttons 6951.

[0147] On the other hand, the failure diagnosis server 500 can separately predict the main inspection target error code corresponding to the cause of failure for the corresponding elevator through the machine learning model in the process of diagnosing the cause of failure, and extract the predicted error code. The predicted error code selection button 6952 corresponding to the predicted error code extracted in this way can be controlled to be different from the display of other error code selection buttons 6951.

[0148] In this way, among the multiple error code selection buttons 6951 displayed on the error code selection input screen 695, the predicted error code selection button 6952 corresponding to the error code predicted as the cause of the failure by the failure diagnosis server 500 can be made to be different from the display of the other error code selection buttons 6951. Through this, in the process of the repair worker inputting the error code for which the failure has been processed, the error code predicted as the cause of the failure can be easily recognized by the repair worker. Therefore, the repair worker can input the error code more accurately with reference to such a predicted error code selection button 6952, and mistakes such as omission of error code input can be prevented.

[0149] On the other hand, even though the display of the predicted error code selection button 6952 is different on the error code selection input screen 695, the repair worker may select another error code selection button 6951 other than the predicted error code selection button 6952. In preparation for such a case, on the error code selection input screen 695, a separate selection confirmation button (not shown) for confirming whether the selection of the corresponding error code selection button 6951 is accurate can be generated.

[0150] Through such a selection confirmation button, the repair worker can be made to confirm again whether the input of the error code is accurate, so that input mistakes of the error code can be more perfectly prevented.

[0151] In this way, due to the different display of the predicted error code selection button 6952 on the error code selection input screen 695, the accuracy of the error code input by the repair worker can be further improved. Through this, the accuracy of the failure processing result input by the repair worker can be improved. Therefore, as described above, the accuracy of the failure diagnosis result of the failure diagnosis server 500 is further improved, and the accuracy of the failure diagnosis result is improved again by the data accumulation of the failure processing result over time. Finally, the error code predicted as the cause of the failure by the failure diagnosis server 500 can be the same as the error code that actually occurred at the actual site. In this case, the input items in the process of inputting the failure processing result by the repair worker can be reduced, and the overall input work of the failure processing result can be greatly simplified. Furthermore, the overall repair work can also be carried out quickly and easily.
