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 smooth floor movement of passengers entering and leaving the corresponding building.

[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 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 terms of 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 arrives at the site, the cause of the failure cannot be grasped in advance.

[0007] Furthermore, there is a problem in that it is difficult to prepare necessary parts and equipment based on the cause of the malfunction during the on-site dispatch process. Therefore, since the necessary parts and equipment for repair work must be prepared only after the on-site inspection, this not only makes the repair work process inefficient but also leads to problems such as longer repair times.

[0008] Furthermore, when an elevator malfunctions, a considerable number of error codes are generated in a short period of time, making it difficult for repair workers to accurately determine the cause of the malfunction based on these error codes. In particular, it is extremely difficult for inexperienced repair workers to pinpoint the main cause of the malfunction based on multiple error codes.

[0020] Furthermore, when the control unit receives a connection input signal from a repair worker via a link address transmitted to the repair terminal via a short message, it can transmit an information request signal corresponding to the link address to the fault diagnosis server, and control the operation to display at least one of the error code information and fault diagnosis results received from the fault diagnosis server upon transmission of the information request signal on the display unit.

[0021] Furthermore, when the control unit receives a connection input signal from a repair worker via a connection button in a pre-set repair management program, it can transfer an information request signal corresponding to the connection button to the fault diagnosis server, and control the operation to display at least one of the error code information and fault diagnosis results received from the fault diagnosis server as a result of the transfer of the information request signal on the display unit.

[0022] Furthermore, when a connection input signal is generated for the link address and a connection input signal is generated through the repair management program, the control unit can transfer an information request signal for the error code information to the fault diagnosis server and control the operation to display the error code information received from the fault diagnosis server on the display unit.

[0023] Also, when an information request input signal for requesting the failure diagnosis result is generated by the input operation of the repair worker, the control unit transfers an information request signal for the failure diagnosis result to the failure diagnosis server, and controls the operation so that the failure diagnosis result received from the failure diagnosis server is displayed on the display unit together with the error code information.

[0024] The failure diagnosis server further includes a failure cause storage unit that stores by matching a plurality of preset reference error code information and at least one or more failure causes respectively corresponding to the reference error code information, and the diagnosis unit can diagnose the failure cause for the error code information based on the data stored in the failure cause storage unit.

[0025] The failure diagnosis server can further include a failure cause update unit that newly matches the failure cause for the reference error code information stored in the failure cause storage unit by reflecting the information on the failure processing result input by the repair worker.

[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 of error code occurrence.

[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 and the diagnosis result for the failure cause stored in the failure diagnosis server are transferred and displayed. The failure diagnosis server classifies a plurality of sequentially generated error code information into one time-series data group for each preset reference time interval, and analyzes the corresponding error code information for each time-series data group to diagnose the failure cause.

[0028] At this time, the failure diagnosis server includes a first communication unit that receives in real time the error code information recorded in the passenger transfer device control panel; an error code storage unit that arranges and stores the error code information received through the first communication unit in chronological order, and classifies and stores it into one time-series data group for each preset reference time interval; a diagnosis unit that analyzes the corresponding error code information for each time-series data group stored in the error code storage unit to diagnose the cause of the failure for the time-series data group; and a second communication unit that receives the information request signal of the repair terminal and transfers the error code information stored in the error code storage unit and the failure diagnosis result by the diagnosis unit to the repair terminal. When receiving an information request signal from the repair terminal, the error code information and the failure diagnosis result can be transferred to the repair terminal.

[0029] In addition, the repair terminal can include an input unit that can be operated by an input operation of a repair operator; a display unit that displays at least one of the error code information and the failure diagnosis result transferred from the failure diagnosis server; a terminal communication unit that communicates with the second communication unit and receives at least one of the error code information and the failure diagnosis result from the failure diagnosis server; and a control unit that transfers an information request signal to the failure diagnosis server through the terminal communication unit when an input signal is generated by the repair operator, and controls the operation to display at least one of the error code information and the failure diagnosis result received from the failure diagnosis server on the display unit according to the transfer of the information request signal.

[0030] In addition, the display unit can include 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, and a diagnosis result display area where the failure diagnosis result for the error code information can be displayed for each time-series data group.

[0031] Furthermore, when a repair worker generates a connection input signal to the fault diagnosis server, the control unit can transfer an information request signal for the error code information to the fault diagnosis server and control its operation to display the error code information received from the fault diagnosis server in the error code display area in a state classified by time-series data group according to the information request signal.

[0032] Furthermore, the control unit can control the operation so that, when the error code information is displayed in the error code display area classified by time-series data group, a diagnostic result request input button is formed in the diagnostic result display area, which can input an information request signal for the fault diagnosis result.

[0033] Furthermore, when an input signal is generated requesting the fault diagnosis result via the diagnostic result request input button, the control unit can transfer an information request signal to the fault diagnosis server requesting the fault diagnosis result for the error code information of the corresponding time-series data group corresponding to the diagnostic result request input button. When the fault diagnosis result is received from the fault diagnosis server in accordance with the information request signal, the control unit can remove the diagnostic result request input button from the diagnostic result display area and simultaneously control the operation to display the fault diagnosis result.

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

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

[0036] On the other hand, the present invention provides a control method for a passenger transport device maintenance system including a fault diagnosis server and a repair terminal, comprising the steps of: the fault diagnosis server collecting and storing error code information of the passenger transport device from the passenger transport device control panel; the fault diagnosis server diagnosing the cause of the failure based on the collected error code information; and the repair terminal connecting to the fault diagnosis server to transfer and display the error code information and the diagnosis results for the cause of the failure stored in the fault diagnosis server, wherein the fault diagnosis server classifies a plurality of error code information that has occurred in sequence into a time-series data group for each predetermined reference time interval, and analyzes the corresponding error code information for each time-series data group to diagnose the cause of the failure.

[0037] The present invention provides a maintenance system for a passenger transport device, comprising: a fault diagnosis server that collects and stores error code information of a passenger transport device from a passenger transport device control panel and diagnoses the cause of a failure based on the collected error code information; and a repair terminal that connects to the fault diagnosis server and receives and displays the error code information and diagnostic results for the cause of the failure stored in the fault diagnosis server, wherein the repair terminal is configured to allow a repair worker to select some of the error code information from a plurality of error code information displayed on the repair terminal and to request a fault diagnosis result for the selected error code information from the fault diagnosis server, and the fault diagnosis server analyzes the error code information selected by the repair terminal in accordance with the information request signal from the repair terminal to diagnose the cause of the failure and transfers the fault diagnosis result to the repair terminal.

[0038] At this time, the fault diagnosis server includes a first communication unit that receives the error code information recorded in the passenger transport device control panel in real time; an error code storage unit that arranges and stores the error code information received through the first communication unit in chronological order; a diagnosis unit that analyzes the error code information selected through the repair terminal from the error code information stored in the error code storage unit to diagnose the cause of the fault; and a second communication unit that receives an information request signal from the repair terminal and transfers the error code information stored in the error code storage unit and the fault diagnosis results from the diagnosis unit to the repair terminal. Upon receiving an information request signal from the repair terminal, the server can transfer the error code information and fault diagnosis results to the repair terminal.

[0039] Furthermore, the repair terminal may include an input unit that a repair worker can input; a display unit that displays the error code information and fault diagnosis results transferred from the fault diagnosis server; a terminal communication unit that communicates with the second communication unit and receives the error code information and fault diagnosis results from the fault diagnosis server; and a control unit that, when an input signal is generated by a repair worker, transfers an information request signal to the fault diagnosis server via the terminal communication unit, and controls the operation to display at least one of the error code information and fault diagnosis results received from the fault diagnosis server on the display unit in accordance with the transfer of the information request signal.

[0040] Furthermore, the display unit includes a first output screen having an error code display area in which the error code information is displayed in a state classified by the time-series data group, and the first output screen may have a selection mode conversion button that converts the error code information displayed in the error code display area into a selection screen mode that can be selected by a repair worker, and a diagnostic result request input button that can request a fault diagnosis result for the error code information selected in the selection screen mode from the fault diagnosis server.

[0041] Furthermore, the display unit includes a selection diagnostic output screen that displays error code information selected by the repair worker and the fault diagnosis result for the selected error code information. When an input signal is generated by the diagnostic result request input button, the control unit transmits an information request signal to the fault diagnosis server requesting the fault diagnosis result for the selected error code information. When the fault diagnosis result is received from the fault diagnosis server in accordance with the information request signal, the control unit can control the operation so that the error code information and the fault diagnosis result are displayed on the selection diagnostic output screen.

[0042] Furthermore, the selection diagnostic output screen can be displayed so as to overlap with the first output screen.

[0043] On the other hand, the present invention provides a control method for a passenger transport device maintenance system including a fault diagnosis server and a repair terminal, comprising the steps of: the fault diagnosis server collecting and storing error code information of the passenger transport device from the passenger transport device control panel and diagnosing the cause of a failure based on the collected error code information; and the repair terminal being connected to the fault diagnosis server and the diagnostic results for the error code information and the cause of the failure stored on the fault diagnosis server being transferred and displayed, wherein the repair terminal is configured so that a repair worker can select some of the error code information of a plurality of error code information displayed on the repair terminal and can request a fault diagnosis result for the selected error code information from the fault diagnosis server, and the fault diagnosis server analyzes the error code information selected by the repair terminal in accordance with the information request signal from the repair terminal to diagnose the cause of the failure and transfers the fault diagnosis result to the repair terminal. [Effects of the Invention]

[0044] According to the present invention, when a passenger transport device malfunctions, repair workers can check the error code information in advance before being dispatched to the site, and prepare the necessary parts and equipment, thereby improving the maintenance efficiency of the passenger transport device.

[0045] According to the present invention, since information regarding the cause of the failure is provided to the repair terminal, repair workers can check the information regarding the cause of the failure not only at the site of the failure but also at locations other than the site of the failure.

[0046] Furthermore, repair workers can prepare parts and equipment in advance to address the cause of the malfunction before being dispatched to the site, thus improving the planning and time required for repair work.

[0047] Furthermore, even novice repair workers can easily assess the malfunction and take appropriate action.

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

[0049] Furthermore, since the cause of the failure can be diagnosed separately for error code information that occurred during a specific time period, the failure diagnosis process can be further subdivided, improving the accuracy of the failure diagnosis.

[0050] Furthermore, repair workers can prepare parts and equipment corresponding to the cause of the malfunction in advance before being dispatched to the site, which improves the planning and time required for repair work and enhances the efficiency of maintenance work.

[0058] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. First, when assigning reference numerals to the components in each drawing, it should be noted that the same components should have the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present invention, if a specific description of a related known configuration or function is deemed to deviate from the gist of the present invention, such detailed description will be omitted.

[0059] First, the passenger transport device according to the present invention includes elevators, escalators, and moving walkways. The following description will focus on elevators.

[0060] Figure 1 is a conceptual diagram illustrating the overall configuration of an elevator maintenance system according to one embodiment of the present invention, and Figure 2 is a conceptual diagram illustrating the overall configuration of an elevator maintenance system according to another embodiment of the present invention.

[0061] An elevator maintenance system according to one embodiment of the present invention comprises a fault diagnosis server 500 that collects error code information from the elevator control panel 100 and diagnoses the cause of the failure, and a repair terminal 600 that connects to the fault diagnosis server 500 and receives and displays the error code information and fault diagnosis results.

[0062] First, looking at the overall system configuration, an elevator may include a control panel 100 that controls the elevator's operating status. The control panel 100 can receive signals related to the elevator's operating status information. The control panel can receive various fault signals. The elevator's operating status information and fault signals may be generated by numerous sensors installed in the elevator. The control panel 100 can receive the elevator's operating status information and fault signals through these sensors. Such a control panel 100 can receive and store signals related to the elevator's operating status and faults. When a fault signal is generated, the control panel 100 can generate an error code that matches the fault signal.

[0063] Operating status signals and error code information can be transmitted in real time to the central management server 400 via the communication unit 200. As shown in Figure 1, the communication unit 200 can communicate with the central management server 400 via the modem 310 and transmit operating status signals and error code information. As shown in Figure 2, if a separate monitoring panel exists, the communication unit 200 can communicate with the central management server 400 via the monitoring panel server 320 and transmit the relevant information.

[0064] The central management server 400 can forward the received information to a separate fault diagnosis server 500. The fault diagnosis server 500 can receive operating status signals and error code information. The fault diagnosis server 500 can be configured as a cloud server and connected to the repair terminal 600 via the internet network. The elevator operating status information and error code information received by the fault diagnosis server 500 can be forwarded to the repair terminal 600. On the repair terminal 600, the user can connect to the fault diagnosis server 500 through an application program to receive the elevator operating status information and error code information. The fault diagnosis server 500 can also analyze the received error code information to analyze the cause of the failure. The fault diagnosis server 500 can derive a diagnosis result for the cause of the failure. The fault diagnosis result thus derived can be provided to the repair terminal 600 through the application program on the repair terminal 600.

[0065] When an elevator malfunction signal is generated or a malfunction report is received, a repair worker may be selected according to the maintenance system. The selected repair worker may be provided with basic information about the elevator in question. This basic information may include the malfunction report status or the elevator's basic specifications.

[0066] In one embodiment of the present invention, an elevator maintenance system can transmit error codes and fault diagnosis results to a repair terminal via a fault diagnosis server 500. Repair workers can prepare necessary parts and equipment before being dispatched. This can shorten the fault handling time and make fault handling work easier.

[0067] The following describes in more detail the detailed configuration of an elevator maintenance system according to one embodiment of the present invention.

[0068] Figure 3 is a block diagram functionally illustrating the configuration of a fault diagnosis server and a repair terminal in an elevator maintenance system according to one embodiment of the present invention; Figures 4 and 5 are diagrams illustrating, in an example, the fault diagnosis server connection method and fault diagnosis result display method of the repair terminal in an elevator maintenance system according to one embodiment of the present invention; and Figure 6 is a diagram illustrating, in an example, the form of error code information displayed in a repair terminal according to one embodiment of the present invention.

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

[0070] The fault diagnosis server 500 collects and stores elevator error code information from the elevator control panel 100 and can diagnose the cause of the fault based on the collected error code information. The repair terminal 600 connects to the fault diagnosis server 500 and can receive and display the error code information and diagnostic results for the cause of the fault stored in the fault diagnosis server 500.

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

[0072] The first communication unit 501a receives error code information recorded in the elevator control panel 100 in real time. As mentioned 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 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 elevator operating status information. For example, the first communication unit 501a can receive general elevator operating status information such as elevator speed, floor number, door operating status, and sensing signals from various sensors. In particular, the first communication unit 501a can receive a variety of information, such as information on changes in the elevator operating status at the time the error code occurred.

[0073] The error code storage unit 502 can store error code information and elevator operating status information received through the first communication unit 501a. The diagnostic unit 503 can diagnose the cause of the failure by analyzing the error code information stored in the error code storage unit 502. The diagnostic 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 information request signals from the repair terminal 600. The second communication unit 501b can transfer error code information stored in the error code storage unit 502 and fault diagnosis results derived by the diagnostic unit 503 to the repair terminal 600. Various types of information, such as elevator operating status information stored in the error code storage unit 502, can also be transferred to the repair terminal 600 by the second communication unit 501b.

[0075] The fault diagnosis server 500 can collect error codes and elevator operating status information recorded in the elevator control panel 100 via 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 corresponding to the error code via the diagnosis unit 503. The fault diagnosis server 500 can also transfer error code information, fault diagnosis results, elevator operating status information, etc., to the repair terminal 600.

[0076] The repair terminal 600 may refer to a wireless communication 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.

[0077] The input unit 603 can be formed on the repair terminal 600 so that repair workers can perform input operations. The input unit 603 can be formed on the repair terminal 600 using a touch operation method via a touch panel, or it can be formed in various forms such as separate physical buttons.

[0078] The display unit 602 can display error code information, fault diagnosis results, and elevator operating status information 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 information request signals, etc., to the fault diagnosis server 500, and receive error code information, fault diagnosis results, elevator operating status information, etc., from the fault diagnosis server 500.

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

[0081] When an elevator malfunction signal is generated, a repair worker is selected, and basic information regarding the elevator in question can be provided to the selected repair worker via the repair terminal 600. In one embodiment of the present invention, error code information and fault diagnosis results may be additionally transmitted to the repair terminal 600 via the fault diagnosis server 500.

[0082] In one embodiment of the present invention, as shown in Figure 4, a confirmation request notification message requesting confirmation of the fault diagnosis results may be sent to the repair worker's repair terminal 600. The confirmation request notification message may include a web link address CL of a fault diagnosis server where the fault diagnosis results can be confirmed. The confirmation request notification message can be sent to the repair worker's mobile phone or repair terminal via SMS forwarding, as shown in Figure 4.

[0083] A connection input signal for the web link address CL can be generated when a repair worker touches the web link address CL included in an SMS-based confirmation request notification message. The control unit 604 can forward an information request signal corresponding to the web link address CL to the fault 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 fault diagnosis results received from the fault diagnosis server 500 are displayed on the display unit 602 according to the forwarding of the information request signal.

[0084] In other words, by touching the web link address CL of the confirmation request notification message transferred to the repair terminal 600, the repair worker can connect to the fault diagnosis server 500 and check the error code and fault diagnosis results, etc.

[0085] On the other hand, as shown in Figure 5, the system can be configured so that a repair worker connects to the fault diagnosis server through a separate repair management program provided on the repair terminal. For example, a connection button CB may be formed in the repair management program of the repair terminal. When a repair worker touches the connection button CB, a connection input signal to the fault diagnosis server 500 may be generated. The control unit 604 can transmit an information request signal corresponding to the connection button CB to the fault diagnosis server 500 in accordance with such a connection input signal, and can control the operation so that the error code information and fault diagnosis results received from the fault diagnosis server 500 are displayed on the display unit 602 in accordance with the transmission of the information request signal.

[0086] In other words, by touching the connection button CB formed in the repair management program of the repair terminal 600, the repair worker can connect to the fault diagnosis server 500 and check the error code and fault diagnosis results. At this time, the connection button CB can be formed in the form of a button displaying a message such as "Fault Diagnosis Connection," as shown in Figure 5.

[0087] In the repair management program, while reviewing past fault handling results, if it is necessary to refer to past error code information and other fault information for the relevant elevator, past error code information and fault diagnosis results can be accessed via the connection button CB. In other words, the repair management program allows repair workers to check error code information and fault diagnosis results for the relevant elevator at any time as needed by touching the connection button CB. This improves the accuracy of repair work and allows new employees to use this information as reference for repair work.

[0088] In summary, when an elevator malfunction occurs, basic information about the elevator is transmitted to the repair terminal of the selected repair worker, and at the same time, a confirmation request notification regarding the elevator's error code and fault diagnosis result may be transmitted. This can be done using a short message system. When a connection input signal is generated through the link address CL or the connection button CB of the repair management program included in the short message, an information request signal is transmitted to the fault diagnosis server 500, and the error code and fault diagnosis result are received from the fault diagnosis server 500 and can be displayed on the display unit 602 of the repair terminal 600.

[0089] Therefore, repair workers can check the error code and fault diagnosis results of the elevator in question before dispatching to the scene of the malfunction, allowing them to prepare the necessary parts and equipment in advance.

[0090] On the other hand, the error code storage unit 502 of the fault diagnosis server 500 can store error code information received through the first communication unit 501a in chronological order. The error code storage unit 502 can classify and store error code information into a single time-series data group for 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 and diagnose the cause of the failure for that time-series data group.

[0091] Furthermore, the display unit 602 of the repair terminal 600 may have a first output screen 610, as shown in Figures 4 and 5, which includes an error code display area 611 for displaying error code information and a diagnostic result display area 612 for displaying fault diagnosis results. The error code display area 611 may display at least one error code arranged in chronological order, and may be classified and displayed according to a time-series data group classified by the fault diagnosis server 500. In other words, one time-series data group may be displayed in one error code display area 611. In this case, one diagnostic result display area 612 may be formed to correspond to one error code display area 611, so that a fault diagnosis result is displayed for each time-series data group.

[0092] Furthermore, as illustrated in Figure 6, each error code information displayed in the error code display area 611 includes the error code name EN, the time the error code occurred ET, and the elevator's operating status information ED at the time the error code occurred. In addition, activation information EA for the corresponding error code may also be displayed.

[0093] For example, the error code name EN represents the type of error code and may be displayed as "ER_HUP_BTN_JAM," with the time ET of the error code occurrence displayed in the area below it. The elevator operating status information ED at the time the error code occurred may display the floor number, current speed / maximum speed (Figure 6 shows it as 3rd floor, current speed 0 / maximum speed 120), etc. The error code activation information EA indicates whether the error code is currently activated or deactivated. As shown in Figure 6, if it displays "OFF," it means the error code is currently deactivated.

[0094] With this structure, when a repair worker connects to the fault diagnosis server 500 via the repair terminal 600, the repair terminal 600 displays error code information and fault diagnosis information for the elevator in question. At this time, the error code information includes the error code name, the time of occurrence, and the operating status information of the elevator. 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 infer the fault diagnosis result themselves from the related error code information.

[0095] In other words, in one embodiment of the present invention, a repair worker can connect to the fault diagnosis server 500 via the repair terminal 600 to check all error codes that have occurred in the elevator in question, allowing them to predict and judge the situation at the site in advance before dispatching to the site.

[0096] In this way, in addition to fault diagnosis results, error codes and elevator operating status information are provided through the repair terminal 600. This allows experienced repair workers to independently determine fault causes that differ from the fault diagnosis results provided by the fault diagnosis server 500, potentially enabling more accurate predictions and on-site responses. Furthermore, novice repair workers can use the fault diagnosis results provided by the fault diagnosis server 500 as a reference to perform on-site responses more smoothly.

[0097] Furthermore, although a large number of error codes occur in the time immediately before and after a malfunction occurs, the fault diagnosis server 500 can receive error code information detected by the elevator control panel 100 in real time. Because it can collect all error code information and elevator operating status information that occurred in the time immediately before and after the malfunction occurs, it can derive more accurate fault diagnosis results.

[0098] Furthermore, by classifying error codes that occur sequentially at very short time intervals into time-series groups based on a reference time unit, and diagnosing the cause of failure on a time-series group basis, it is possible to derive faster and more accurate diagnostic results. The reference time can be set by the error code storage unit 502 of the fault diagnosis server 500.

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

[0100] On the other hand, the fault diagnosis server 500 can be equipped with a fault diagnosis program that can analyze error code information to diagnose the cause of a fault. The fault diagnosis program can be configured to diagnose the cause of a fault based on information pre-entered by an experienced technician.

[0101] To this end, the fault diagnosis server 500 may include a fault cause storage unit 504 that matches a plurality of pre-specified reference error code information with at least one fault cause corresponding to each reference error code information and stores them.

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

[0103] Furthermore, once the repair work at the repair site is completed, the repair worker can input the fault processing results. At this time, the input fault processing results can be transferred to the fault diagnosis server 500 via the central management server 400. The fault diagnosis server 500 can then modify the information stored in the fault cause storage unit 504 by reflecting the information regarding the fault processing results from the repair worker.

[0104] To this end, the fault diagnosis server 500 may include a fault cause update unit 505 that reflects information on the fault processing results entered by the repair worker and newly matches the fault cause with the reference error code information stored in the fault cause storage unit 504.

[0105] The fault cause update unit 505 updates the information on error codes and fault causes stored in the fault cause storage unit 504, and the accuracy of the information on error codes and fault causes can increase as the amount of fault processing result data increases. Therefore, in the elevator maintenance system according to one embodiment of the present invention, the accuracy and reliability of the fault diagnosis results of the fault diagnosis server 500 can improve as the period of use increases.

[0106] On the other hand, if an error occurs in the communication state between the elevator control panel 100, the central management server 400, and the fault 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 fault diagnosis server 500 during the period of the error. In this case, since not all error code information is transferred to the fault diagnosis server 500, the accuracy of the fault diagnosis result obtained by the fault diagnosis server 500 based on the error code information may decrease. To address this, a manual collection button can be provided on the first output screen 610 of the repair terminal 600. When a repair worker touches the manual collection button, error code information and other data can be collected again from the elevator control panel 100 to the fault diagnosis server 500 for a certain period of time.

[0107] Figure 7 is a diagram illustrating an exemplary method for displaying fault diagnosis results in a repair terminal according to one embodiment of the present invention.

[0108] In one embodiment of the present invention, as described above, when an information request signal is transmitted from the repair terminal 600 to the fault diagnosis server 500 in accordance with the connection input signal, the fault diagnosis server 500 transmits error codes and fault diagnosis results to the repair terminal 600 for display in time-series data groups.

[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 Figure 7, multiple 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 requesting a fault diagnosis result is transferred through the repair terminal 600, the diagnostic unit 503 of the fault diagnosis server 500 can diagnose the cause of the fault for each error code for each time-series data group. The fault diagnosis server 500 can then transfer and display the corresponding fault diagnosis result to the repair terminal 600.

[0110] In other words, instead of providing fault diagnosis results for an error code in a time-series data group immediately by connecting to the fault diagnosis server 500, the fault diagnosis server 500 can be configured to diagnose the cause of the failure through a fault diagnosis program and provide the fault diagnosis results to the repair terminal when a repair worker requests the relevant diagnosis results.

[0111] To explain in more detail, when a repair worker touches the link address CL, which has been transmitted to the repair terminal 600 via a short message, or touches the connection button CB of the repair management program, generating a connection input signal, the control unit 604 of the repair terminal 600 can control its operation to transmit an information request signal regarding error code information to the fault diagnosis server 500. When the fault diagnosis server 500 receives such an information request signal, it transmits the error codes stored in the error code storage unit 502 to the repair terminal 600 in time-series data groups, and the control unit 604 of the repair terminal 600 can control its operation so that the transmitted time-series data group-specific error codes are displayed on the display unit 602.

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

[0113] In this display state, if a repair worker touches the diagnostic result request input button 613 for any one of the time-series data groups, an input signal requesting a fault 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 to the fault diagnosis server 500 requesting a fault diagnosis result for the error code information of the time-series data group corresponding to the diagnostic result request input button 613. The fault diagnosis server 500 diagnoses the cause of the fault for the error code of the time-series data group in accordance with such an information request signal through the diagnosis unit 503 and derives a diagnosis result. The derived fault diagnosis result may be transferred from the fault diagnosis server 500 to the repair terminal 600. The control unit 604 of the repair terminal 600 can control its operation to display the transferred fault diagnosis result of the time-series data group in the diagnostic result display area 612 of the first output screen 610 for the corresponding time-series data group. 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. In other words, when the fault diagnosis result is transferred to the repair terminal 600, as shown in Figure 7(b), the fault diagnosis result can be displayed in the diagnostic result display area 612 at the same time that the diagnostic result request input button 613 is removed.

[0114] The diagnostic result request input button 613 formed in the diagnostic result display area 612 can be configured to allow touch operation in a form that displays the message "Call".

[0115] With this structure, the fault diagnosis server 500 can diagnose the cause of a fault for a specific time-series data group only when a fault diagnosis result request signal is transferred from the repair terminal 600. Therefore, it is not necessary to iteratively diagnose the cause of faults for all past error codes, and it is not necessary to separately store fault diagnosis results for all past error codes, thus preventing overload on the fault diagnosis server 500 and reducing its capacity.

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

[0117] For example, as illustrated in Figure 7(b), the first fault diagnosis result for the time-series data group is displayed as "Platform Up Button Entrapment (100%)". This means that the cause of the failure is the up button on the platform being caught, and the probability of this failure is 100%. The second fault diagnosis result for the time-series data group may be displayed as "Door Motor Failure (75%), Door Entrapment (25%)". This may mean that there is a 75% probability that the cause of the failure is a door motor failure, and a 25% probability that the cause is door entrapment.

[0118] By displaying probability information related to the cause of the failure, repair workers can consider this information when determining the order of operations during the failure resolution process, enabling them to perform repair work more quickly and accurately.

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

[0120] Figure 8 is a diagram illustrating an example of a screen that displays the fault diagnosis results for error code information selected by the user in an elevator maintenance system according to one embodiment of the present invention.

[0121] As described above, the elevator maintenance system according to one embodiment of the present invention can classify several error code information into a time-series data group for each reference time interval and provide fault diagnosis results based on the error code information for each individual time-series data group. In addition, as shown in Figure 8, a repair worker can select some of the error code information from multiple error code information, and the selected error code information can be separately analyzed and a fault diagnosis result based on the corresponding error code information can be provided to the repair terminal 600.

[0122] As described above, the display unit 602 of the repair terminal may include a first output screen 610 having an error code display area 611 and a diagnostic result display area 612. The first output screen 610 may have a selection mode conversion button 631, as shown in Figure 8, which converts the error code information displayed in the error code display area 611 into a selection screen mode that allows the repair worker to select an error code. When the repair worker touches the selection mode conversion button 631, the screen 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 shown in Figure 8(a) exemplifies the state when it has been converted to selection screen mode. In this selection screen mode, the repair worker can select multiple error code information by touch operation. Figure 8(a) exemplifies the state in which three error code information has been selected.

[0123] Furthermore, the first output screen 610 includes a selection diagnostic result request input button 632 that allows the user to request a fault diagnosis result from the fault diagnosis server 500 for the error code information selected in the selection screen mode.

[0124] In this case, the selection mode conversion button 631 and the selection diagnostic result request input button 632 may be automatically generated at the same time that the first output screen 610 is displayed on the display unit 602. However, as shown in Figure 8(a), the selection mode conversion button 631 and the selection diagnostic result request input button 632 can be generated on the first output screen 610 by touching the setting button 630 which is automatically generated on the first output screen 610.

[0125] After a repair worker touches the selection mode conversion button 631 to switch the first output screen 610 to the selection screen mode, they can select some error code information. Once the selection of error code information is complete, the repair worker can touch the selection diagnostic result request input button 632. When an input signal is generated by touching the selection diagnostic result request input button 632, the control unit 604 can control its operation to transfer an information request signal requesting a fault diagnosis result for the selected error code information to the fault diagnosis server 500. Subsequently, the diagnostic unit 503 of the fault diagnosis server 500 can analyze the cause of the fault for the selected error code information and derive a fault diagnosis result along with probability information. The derived fault diagnosis result can then be transferred to the repair terminal 600.

[0126] The repair terminal 600 may have a selection diagnostic output screen 620 that can display error code information selected by the repair worker and the fault diagnosis results for the selected error code information. The control unit 604 can control the operation so that the fault diagnosis results transferred from the fault diagnosis server 500 to the repair terminal 600 are displayed on the selection diagnostic output screen 620 together with the selected error code information. At this time, the selection diagnostic output screen 620 can be displayed so as to overlap the first output screen 610, as shown in Figure 8(b). The selection diagnostic output screen 620 may have a selection error code display area 621 where the selected error code information is displayed and a selection diagnostic result display area 622 where the fault diagnosis results for that information are displayed, in the same form as the first output screen 610.

[0127] On the other hand, there are no particular restrictions on the range of error code information that a repair worker can select. In other words, it is possible to select some of the error code information within the same time-series data group, or to select one or more error code information from different time-series data groups. Figure 8 illustrates an example where two error code information is selected from one time-series data group and one error code information is selected from another time-series data group.

[0128] In this way, by separately diagnosing error code information selected by the user through the fault diagnosis server, it is possible to obtain fault diagnosis results for a wider variety of error code information, depending on the user's selection, in addition to the fault diagnosis results for the error code information of the time-series data group. In particular, by selecting such error code information, it is possible to separately diagnose the cause of the failure targeting error code information for a specific time period, for example, the time when passengers were trapped. This can further improve the efficiency of repair work.

[0129] The above description is merely illustrative of the technical concept of the present invention, and a person with ordinary skill in the art to which the present invention belongs can make various modifications and variations within the bounds of the essential characteristics of the present invention. Therefore, the embodiments disclosed herein are for illustrative purposes only and not to limit the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by such embodiments.
