Description

  The present invention relates to a lift monitoring system for remotely monitoring a lift such as an elevator or an escalator from a monitoring center.

  Elevator remote monitoring systems that remotely monitor elevator operations such as elevators and escalators at a monitoring center via communication lines have been put into practical use. In such a remote monitoring system, for example, there is a case where a diagnostic function for performing automatic diagnosis on the elevator at a predetermined cycle such as once a month is incorporated.

  In the case of an elevator, for example, in the case of an elevator, it is considered that a virtual hall call or car call is generated during a time when there is no elevator user such as midnight, and the elevator is actually tested and operated. It is done. Then, it detects whether the car has moved normally to the designated floor and whether the moving speed is within the specified range. Also, the vibration of the car during movement, the stop position error in the car on each floor, the motor current value, the elevator The overall power consumption and the like are measured, and it is determined whether or not each measured value falls within a predetermined allowable range.

  Moreover, the monitoring terminal incorporated in the elevator transmits the determination result as a diagnosis result to the monitoring device of the monitoring center. The operator (monitor) of the monitoring center looks at the diagnosis result displayed on the display panel and confirms the normality / abnormality of each elevator.

  In addition to the automatic diagnosis described above, maintenance personnel belonging to the maintenance management company that operates the monitoring center visit each elevator such as an elevator or escalator to perform maintenance inspection work on each elevator, and the maintenance inspection results Is reported to the monitoring center.

  For example, in the case of an elevator, the maintenance worker performs maintenance and inspection work such as motors, sheaves, car hoisting machines, ropes, control panels, and other components in the machine room above the elevator hoistway. There are degree, inspection of each electrical component, confirmation of emergency contact (interphone) to the monitoring center, oil leak check, etc. Furthermore, there are replacement of parts that are exhausted and simple repair of parts.

  However, as described above, there is still the following problem to be improved in the elevator remote monitoring system that incorporates a diagnosis function for the elevator to be monitored.

  That is, for example, it is assumed that a maintenance staff replaces a specific part with a new part in the inspection and maintenance work. However, failures often occur immediately after replacement of parts. This is because there is a causal relationship of failure occurrence rate characteristics between the elapsed time from the start of use of each component and the failure occurrence rate. This failure rate characteristic is referred to as a bathtub characteristic, and is a phenomenon in which the failure rate in the initial period and the final period in the life time of a part is extremely higher than the failure rate in the middle period.

  However, since conventional automatic diagnosis is carried out at regular intervals, such as once a month, it is not possible to find a defect immediately after replacing a part in a short time, and as a result, it is impossible to grasp the discovery of a failure in advance. . Similarly, there is a concern that the same situation may occur in the end of life. Conversely, in the middle period of the service life, although the failure rate is low, as a result, frequent diagnosis is performed, and the communication line of the monitoring center is occupied unnecessarily, and the processing burden is reduced. Increase.

  This invention is made | formed in view of such a situation, and it aims at providing the remote monitoring system of the elevator which can implement efficiently the diagnosis of elevators, such as an elevator and an escalator to be monitored.

  The present invention relates to an equi-elevator equipped with a monitoring terminal that performs diagnosis on the elevator built into the elevator and a monitoring device that performs remote monitoring on the elevator based on a diagnosis result received from the monitoring terminal via a communication line. In the remote monitoring system, the monitoring device performs diagnosis in the elapsed time region where the failure occurrence rate is high based on the failure occurrence rate characteristic indicating the relationship between the elapsed time from the start of use of the components constituting the elevator and the failure occurrence rate. A parts database that stores a diagnosis execution pattern in which the execution period is set short and the execution period is set long in the elapsed time region where the failure rate is low, and part replacement information that specifies the date of replacement of the elevator and the parts constituting the elevator In response to the input, a diagnosis schedule including actual diagnosis execution date information was created from the diagnosis execution pattern of the part in the parts database, and the parts were replaced. And a diagnosis schedule transmission means for transmitting through the communication line to the disembarkation of the monitoring terminal. Then, the monitoring terminal performs diagnosis according to the diagnosis schedule received from the monitoring device.

  In another invention, the parts replacement information in the elevator remote monitoring system of the above invention is included in a maintenance inspection result transmitted from a portable terminal used by a maintenance worker who performs maintenance inspection of the elevator to a monitoring device via a communication line. It is.

  In another aspect of the invention, the monitoring device in the elevator remote monitoring system according to the invention is created in accordance with a setting diagnosis schedule memory for storing and holding the diagnosis schedule transmitted to the elevator monitoring terminal and a new part replacement information input. And a diagnostic schedule synthesizing means for synthesizing the diagnostic schedule and the diagnostic schedule stored in the set diagnostic schedule memory and transmitting the synthesized schedule to the monitoring terminal of the elevator whose parts have been replaced.

  Another invention relates to the above-described invention in which a monitoring terminal incorporated in an elevator for diagnosis of the elevator, a portable terminal used by maintenance personnel for maintenance of the elevator, and a communication line for the monitoring terminal and the portable terminal. And is applied to a remote monitoring system for an elevator including a monitoring device that performs remote monitoring on the elevator based on a diagnosis result and a maintenance inspection result received from the monitoring terminal and the portable terminal.

  In another invention, the above-described invention is incorporated into an elevator, a monitoring terminal that performs diagnosis and monitoring of the occurrence of abnormality of the elevator, a portable terminal that is used by each maintenance person who performs maintenance and inspection of the elevator, a monitoring terminal, and a portable terminal Remote monitoring of an elevator equipped with a monitoring device for remotely monitoring the elevator based on diagnosis results, monitoring results and maintenance inspection results received from a monitoring terminal and a portable terminal. Applied to the system.

  In the elevator remote monitoring system of the present invention, it is possible to efficiently carry out diagnosis of elevators such as elevators and escalators to be monitored.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic diagram showing a schematic configuration of a remote monitoring system for an elevator according to an embodiment of the present invention. In the following description, an elevator is exemplified as an elevator, but the present invention can also be applied to other elevators such as an escalator.

  In each building 1 distributed in the same area, one or a plurality of elevators 2 as monitoring targets are provided. Each building 1 incorporates a monitoring terminal 3 that constantly monitors the operating state of each elevator 2 in one or a plurality of elevators 2 incorporated in the building 1 and automatically executes diagnosis for the elevator 2. It is. Each monitoring terminal 3 is connected to a monitoring device 6 in the monitoring center 5 via a communication line 4 made of, for example, a public telephone line.

  The elevator maintenance management company that operates the monitoring center 5 allows the maintenance staff 7 to carry the portable terminal 8. The mobile terminal 8 has a function of exchanging various types of information including a voice call to the operator 23 via the mobile phone line 9 with the monitoring center 5 and monitoring the monitoring center 4 via the Internet 10. A site provided in the device 6 can be accessed.

  FIG. 2A is a schematic configuration diagram of each elevator 2. In the machine room 12 provided in the upper part of the elevator hoistway 11, the three-phase alternating current supplied from the external three-phase alternating current power supply 13 is controlled based on the operation command from the operation control unit 29. 14, power is converted (AC → DC → AC) and supplied to a motor (induction motor) 15. The motor 15 controls the rotation of the main sheave 16. A rope 20 having a car 18 and a counterweight 19 attached to both ends is wound around the main sheave 16 and the sub sheave 17.

  As shown in FIG. 2 (b), an operation panel 21 operated by a user of the elevator 2 is attached in the car 18 of each elevator 2. The operation panel 21 includes a car call button 22 for designating a destination floor of the car 18, an emergency button 24 to be pressed when calling the operator 23 of the monitoring center 5 when a confinement accident occurs, and an abnormality in the operator 23 of the monitoring center 5. A microphone 25 for informing the state, a speaker 26 for outputting voice instructions from the operator 23, and the like are provided.

  Further, a sticker of a two-dimensional code 27 is affixed to the operation panel 21. The two-dimensional code 27 is composed of, for example, a QR code (registered trademark). In this embodiment, the address of the building 1, the customer name (company name or the owner name of the building), the elevator 2 unit, the individual Each information such as a machine ID for identifying the elevator 2 is included.

  The operation control unit 29 in FIG. 2 (a) sends a drive signal to the power conversion unit 14 according to the car call and the hall call of the car call button 22 in the car 18 and the hall call button 28 provided in the elevator hall on each floor. Is applied to drive the motor 15 to control the movement of the car 18 to the floor designated by the car call and the hall call.

  As shown in FIG. 3, the mobile terminal 8 possessed by each maintenance staff 7 is transmitted from the input unit 30 for inputting a communication destination telephone number, URL, maintenance inspection result data, and the like, and the monitoring center 5. A display unit 31 for displaying various data including a map, an antenna 32 used for communication with a base station, and a camera 33 for reading a two-dimensional code 27 for specifying the elevator 2 are provided.

  Furthermore, each maintenance person 7 receives a part card 34 on which a dimension code 35 for each part including information such as a part name, a standard (size), and a part ID of each part to be replaced relatively frequently of the elevator 2 is printed. In possession.

  And each maintenance worker 7 goes around the elevator 2 of each building 1 according to a predetermined schedule, and performs maintenance inspection work. Specifically, prior to the start of the maintenance inspection, each maintenance staff 7 takes a picture of the two-dimensional code 27 attached to the car 18 of the elevator 2 to be inspected by the camera 33 of his / her portable terminal 8. Within the terminal 8, the two-dimensional code 27 is decoded and maintenance inspection start information is generated. This maintenance / inspection start information is automatically transmitted to the monitoring device 6 of the monitoring center 5 via the mobile phone line 9. After that, the actual maintenance inspection work will be carried out.

  As described above, the maintenance and inspection work performed by the maintenance staff 7 includes the motor 15, sheaves 16 and 17, the hoisting machine for the car 18, the rope 20, and the power conversion unit in the machine room 12 above the elevator hoistway 11. 14, each component of the control panel, the degree of wear of each part, inspection of each electrical part, confirmation of emergency contact (interphones 24, 25) to the operator 23 of the monitoring center 5, oil leak check, and the like. Furthermore, there are replacement of parts that are highly consumed, simple repair of parts, and the like.

  When the maintenance inspection work is completed, the maintenance staff 7 creates a maintenance inspection result on the display screen of the display unit 31 of the portable terminal 8. In this case, when component replacement is included, the two-dimensional code 35 of the corresponding component in the component card 34 shown in FIG. Finally, when the two-dimensional code 27 pasted in the car 18 is read again by the camera 33, the two-dimensional code 27 is decoded and maintenance inspection end information is generated. This maintenance / inspection end information is automatically transmitted to the monitoring device 6 of the monitoring center 5 via the mobile phone line 9 or the Internet 10. The above is one maintenance inspection work for the elevator 2 performed by the maintenance staff 7.

  FIG. 5 is a schematic configuration diagram of each monitoring terminal 3 incorporated in the elevator 2 of each building 1. The monitoring terminal 3 transmits and receives information to and from the monitoring unit 6 that automatically diagnoses the elevator 2, the monitoring unit 37 that monitors the occurrence of an abnormality in the elevator 2, and the monitoring device 6 of the monitoring center 5 via the communication line 4. The receiving unit 38 and the receiving unit 39 are configured to perform the above.

  A diagnosis sequence for the elevator 2 is stored in the diagnosis sequence memory 40 in the diagnosis unit 36. For example, in the time zone when there is no user of the elevator 2 such as midnight, the operation control unit 29 is activated by actually generating a virtual hall call or car call, and the elevator 2 is actually tested. Then, along with operations such as whether the car 18 has normally moved to the designated floor and whether the moving speed is within a specified range, vibration of the car 18 during movement, stop position error in the car on each floor, current value of the motor 15 The power consumption of the entire elevator 2 is measured, and it is determined whether or not each measured value falls within a predetermined allowable range.

The diagnosis schedule memory 41 stores a diagnosis schedule 46 for diagnosis stored in the diagnosis sequence memory 40 as shown in FIG. The diagnosis schedule 46 includes a plurality of execution periods 46a (t _{1 to} t ₂ ), (t _{2 to} t ₃ ), and (t _{3 to} t ₄ ) indicated by actual dates (months and days). 46a (t ₁ ~t _2), are set (t ₂ ~t _3), carried period 46b in _{(t 3 ~t 4) (T} A, T B, T C). The diagnostic schedule 46 is transmitted from the monitoring device 6 of the monitoring center 5 to the receiving unit 38 via the communication line 4 and is written in the diagnostic schedule memory 41.

  The clock circuit 42 determines which implementation period 46 a in the diagnosis schedule 46 stored in the diagnosis schedule memory 41 corresponds to the current date. Then, every time a period 46 a corresponding to the current implementation period 46 a elapses, a drive command is sent to the test operation command output unit 43 and the operation detection unit 44. The test operation command output unit 43 and the operation detection unit 44 that have input the drive command automatically execute the diagnostic procedure stored in the diagnostic sequence memory 40.

  The motion detection unit 44 sends the above measured values and the like to the determination unit 45. The determination unit 45 determines whether or not each measurement value described above falls within the allowable range, and transmits the diagnosis result to the monitoring device 6 of the monitoring center 5 via the transmission unit 39 and the communication line 4.

  In the monitoring unit 37 of the monitoring terminal 3, power failure detected by each monitoring sensor 47, pit inundation, occurrence of an earthquake, etc., operation of the emergency button 24, sound from the microphone 25, and the like are input to the input interface 50. When the abnormality determination unit 51 determines that these are abnormalities to be transmitted to the monitoring center 5, the abnormality occurrence information transmission unit 52 attaches the elevator ID for identifying the elevator 2 and the abnormality occurrence time to the abnormality type. The “abnormality occurrence information” is generated and transmitted to the monitoring device 6 of the monitoring center 5 via the transmission unit 39 and the communication line 4.

  When a voice instruction for the trapped user is input from the operator 23 of the monitoring center 5 to the reception unit 38, the voice instruction is output from the speaker 26 via the voice output unit 53.

  The monitoring terminal 3 configured in this manner executes diagnosis / monitoring processing for the monitored elevator 2 according to the flowchart shown in FIG.

  When an abnormality such as a power failure, pit inundation, earthquake occurrence, etc. detected by each monitoring sensor 47, operation of the emergency button 24, voice from the microphone 25, etc. are input to the input interface 50, the abnormality determination unit 51 determines that these are abnormal. (Step S1), the abnormality occurrence information transmission unit 52 creates “abnormality occurrence information” in which the elevator ID identifying the elevator 2 and the abnormality occurrence time are added to the abnormality type (S2), and the transmission unit 39, communication line 4 to the monitoring device 6 of the monitoring center 5 (S3). Then, the process returns to S1.

If no abnormality occurs, the current date of the clock circuit 42 is read (S4), and the read current date corresponds to the corresponding period 46a and the corresponding period 46a in the diagnosis schedule 46 stored in the diagnosis schedule memory 41 shown in FIG. The period 46b is read (S5). The elapsed days from the date of the previous diagnosis to the current date are calculated (S6), and when the elapsed days have reached the period 46b (S7), the test operation command output unit 43 and the operation detection unit 44 are driven. A command is transmitted to perform diagnosis (S8). In addition, when the date of the diagnosis performed last time is not stored, the date of the diagnosis performed last time is set as the _first date t ₁ in the diagnosis schedule 46). And a diagnostic result is transmitted to the monitoring apparatus 6 of the monitoring center 5 (S9). Then, the current diagnosis execution date is stored and retained (update of the previous execution date) as the date of the previous diagnosis (S10).

  In S7, when the number of days elapsed since the previous time does not reach the period 46b, it is checked whether or not the reception unit 38 has received a new diagnosis schedule 46 from the monitoring device 6 of the monitoring center 5 (S11). If so, the diagnostic schedule 46 stored in the diagnostic schedule memory 41 is updated to the newly received diagnostic schedule 46 (S12). Thereafter, the process returns to S1.

  As described above, the monitoring terminal 3 in each building 1 constantly monitors the occurrence of abnormality in the elevator 2 and automatically performs diagnosis according to the diagnosis schedule 46 stored in the diagnosis schedule memory 41.

  FIG. 8 is a block diagram illustrating a schematic configuration of the monitoring device 6 provided in the monitoring center 5. In this monitoring device 6, there is a telephone line for communicating with each monitoring terminal 3 of each building 1 via the communication line 4 and communicating with the portable terminal 8 possessed by the maintenance staff 7 via the portable telephone line 9. A communication unit 54 and an Internet communication unit (Web browser) 55 having a site where the portable terminal 8 of the maintenance staff 7 is accessed via the Internet 10 are provided.

  The transmission / reception processing unit 56 transfers various types of information received by the telephone line communication unit 54 and the Internet communication unit 55 to the control unit 57 that performs various types of information processing. Further, the transmission / reception processing unit 57 sends a diagnosis schedule 46, various instructions to the maintenance staff 7 and the like of each building 1 through the telephone line communication unit 54 and the Internet communication unit 55 based on instructions from the control unit 57. The data is transmitted to the monitoring terminal 3 and the portable terminal 8 of the maintenance staff 7.

  Further, in the monitoring device 6, a display unit 59 for displaying the position of each elevator 2 to be monitored and the position of each maintenance person 7 on a map 58 as shown in FIG. 16 and an operator 23 of the monitoring center 5 are provided. An input unit 60 for inputting instructions to the maintenance staff 7 and performing various operations, and a telephone terminal 61 for carrying out a voice call between the operator 23 of the monitoring center 5 and the passenger of the elevator 2 when a confinement accident occurs are provided. ing.

  In the storage unit 62 for storing various information, a parts database 63, a monitoring target database 64, a setting diagnosis schedule memory 65, a maintenance staff database 66, a monitoring / diagnosis / maintenance inspection data memory 67, and a map database 68 are provided. .

  In the parts database 63, as shown in FIG. 9, for each part that is replaced relatively frequently in the elevator 2, a part ID (B01, B02, B03,...) That identifies the corresponding part, a part name, and a standard. (Dimensions etc.) and a diagnosis execution pattern 69 are stored. The diagnosis execution pattern 69 for each component will be described using the failure occurrence rate characteristic 70 shown in FIG.

As described above, each component has the failure rate characteristic 70 indicating the relationship between the elapsed time A from the start of use (A = A ₁ ) and the failure rate B. This failure rate characteristic 70 is referred to as a bathtub-tub curve, and an initial period (A = A _{1 to} A ₂ ) and an end period (A = A = A ₅ ) in the average life time (A = A ₅ ) of this part. Although the failure rate B in A _{3 to} A ₄ ) is high, the failure rate B in the medium period (A = A _{2 to} A ₃ ) is small. A high elapsed time regions fault incidence B initial period (A = A ₁ ~A ₂₎ and shortening the implementation period T of the diagnosis to the final period _{(A = A 3 ~A 4)} (T = T A, T = T _C ), and the execution period T is set longer (T = T _B ) in the medium-term period (A = A _{2 to} A ₃ ), which is an elapsed time region where the failure occurrence rate B is low, for example, T _B > T _A > T _C , or T _B > T _C > T _A , or T _B > T _A = T _C were set.

In FIG. 10, t = t ₁ , t ₂ ,..., T ₅ are actual dates corresponding to each period. Therefore, t = t ₁ is the date when this part is actually attached to the elevator 2.

  The diagnosis execution pattern 69 of the part database 63 stores the diagnosis execution period in each period when the failure occurrence rate characteristic 70 for each part is classified into, for example, three periods of initial, middle period, and period.

  In the monitoring target database 64, as shown in FIG. 11, information of each elevator 2 to be monitored in the monitoring device 6 is stored. That is, for each unit ID (E01, E02,...) That identifies each elevator 2, the location, the building name (elevator unit), and many parts incorporated in the elevator 2 are replaced relatively frequently. A predetermined part ID of each part and a date when the corresponding part is replaced (attached) are stored.

  For example, it is shown that the elevator with the machine ID = E01 is attached with the part with the part ID = B01 on November 8, 2005 and the part with the part ID = B02 is attached on September 1, 2005.

  In the set diagnosis schedule memory 65, as shown in FIG. 14, the diagnosis schedule 46 that is actually set at the present time in the diagnosis schedule memory 41 of the monitoring terminal 3 of each elevator 2, and the diagnosis schedule memory 41 The latest update date (transmission date of the diagnostic schedule 46) 65a is stored.

Next, a method for obtaining the actual diagnosis schedule 46 from the diagnosis execution pattern 69 of each part in the part database 63 will be described with reference to FIGS. 10 and 13. That is, as described above, the current date t ₁ when the component is attached is set to the initial value A = A ₁ = t ₁ of the initial initial period in the diagnosis execution pattern 69. When the top value A = A ₁ = t ₁ diagnostic exemplary pattern 69 is determined, each date t ₁ ~t ₅ of each value A ₂ to A ₅ since it automatically determined from the date interval.

  FIG. 13 shows a procedure for creating one diagnosis schedule 46 by combining the diagnosis execution patterns 69 of two parts. First, diagnostic schedules 46A and 46B are created individually for each of the two components, and then two diagnostic schedules 46A and 46B are combined to create one diagnostic schedule 46C, as shown in the bottom row. As a result, the number of periods increases up to 6 times the maximum. In this case, when two different types of periods occur, the shorter period T is employed in this period for safety.

  If the two diagnosis schedules 46A and 46B do not overlap in time, the combined diagnosis schedule 46C is obtained by connecting the two diagnosis schedules 46A and 46B in series in time.

  In the maintenance worker database 66, as shown in FIG. 12, for each maintenance worker ID (H01, H02,...) That identifies each maintenance worker 7, the name, telephone number (mobile phone number), and “ The current status of “maintenance / inspection work” or “moving” and the ID number of the corresponding elevator 2 in the case of maintenance / inspection work are stored. Specifically, when the maintenance inspection disclosure information decoded from the two-dimensional code 27 is input from the portable terminal 8 of the maintenance staff 7, the current status of the maintenance staff 7 is changed to “under maintenance inspection”, and the corresponding elevator 2 No. machine ID is set. Further, when maintenance inspection end information (maintenance inspection result) is input, the current status of the maintenance staff 7 is changed to “moving”, and the car ID of the corresponding elevator 2 is cleared.

  As shown in FIG. 15, the monitoring / diagnosis / maintenance / inspection data memory 67 sequentially stores an abnormality monitoring result 67a, a diagnostic result 67b, and a maintenance / inspection result 67c for each elevator ID that identifies each elevator 2. At the same time, the current state 67d indicating whether maintenance or inspection work is in progress is stored.

  The diagnosis result 67b is stored with the diagnosis execution date added. The maintenance inspection result 67c is a set of the implementation date and each maintenance inspection result. In addition to “no abnormality”, “part replacement, part B01”, “oil leak”, etc. are written in the maintenance inspection result 67c.

  A map is stored in the map database 68. When a position indicated by address notation is designated, a map 58 is read and displayed on the display unit 59 as shown in FIG.

  On the map 58 displayed and output on the display unit 59, a “◯” mark is displayed at the position of the monitored elevator 2, and a “X” mark is displayed at the position of the maintenance staff 7. The map 58 shown in FIG. 16 is always displayed on the display unit 59 while the monitoring device 6 of the monitoring center 5 is in operation.

  And the control part 57 of the monitoring apparatus 6 of this monitoring center 5 performs monitoring control with respect to each elevator 2 according to the flowchart shown to FIG. 17, FIG.

  When maintenance check start information is input from the mobile terminal 8 possessed by the maintenance staff 7 to the telephone line communication unit 54 via the mobile telephone line 9 (step Q1), the current state of the corresponding maintenance staff in the maintenance staff database 66 is displayed. “Maintenance / inspection” is set, and the state 67d of the corresponding elevator 2 in the monitoring / diagnosis / maintenance / inspection data memory 67 is set to “in operation” (Q2).

  When maintenance inspection end information (maintenance inspection result) is input from the mobile terminal 8 possessed by the maintenance staff 7 via the telephone line communication section 54 or the Internet communication section 55 (Q3), the corresponding maintenance in the maintenance staff database 66 is performed. The current state of the worker is set to “moving”, and the inputted maintenance inspection result 67 c is additionally written in the maintenance inspection result area of the corresponding elevator 2 in the monitoring / diagnosis / maintenance inspection data memory 67. At the same time, the “working” state 67d is cleared (Q4).

If the maintenance inspection result 67c does not include the replacement date (maintenance inspection date) and the part replacement information specifying the part ID (Q5), the process returns to Q1. When the part replacement information is included in the maintenance inspection result 67c, the diagnosis execution pattern 69 of the part with the corresponding part ID stored in the part database 63 of FIG. 9 is read. Then, as described above, by setting the current date (maintenance check date) to the initial value A = A ₁ = t ₁ of the initial initial period of the diagnosis execution pattern 69, the actual date is obtained from the diagnosis execution pattern 69. The entered diagnostic schedule 46 is created (Q6).

  Next, it is checked whether or not the diagnosis schedule 46 is already set in the column of the elevator 2 that has undergone the current maintenance check in the setting diagnosis schedule memory 65 of FIG. 14 (Q7). If not set (Q8), the diagnosis schedule 46 created this time is newly set in the column of the corresponding elevator 2 (unit ID). At the same time, the current date (maintenance inspection date) is written as the last update date 65a (Q9).

  When the diagnosis schedule 46 has already been set (Q8), the already set diagnosis schedule 46 and the currently created diagnosis schedule 46 are combined using the method described in FIG. Then, the previous old diagnosis schedule 46 is rewritten to the new diagnosis schedule 46 synthesized. At the same time, the current date (maintenance inspection date) is written as the last update date 65a (Q10).

  Then, the newly set or updated diagnosis schedule 46 of the corresponding elevator 2 in the setting diagnosis schedule memory 65 is read and transmitted to the monitoring terminal 3 of the elevator 2 whose parts have been replaced via the communication line 4 (Q11). And it returns to Q1.

  In Q12 of FIG. 17, when a diagnosis result is input from the monitoring terminal 3 to the telephone line communication unit 54 via the communication line 4, this diagnosis result 67b is stored in the monitoring / diagnosis / maintenance inspection data memory 67 shown in FIG. Is added to the diagnosis result column of the corresponding elevator 2 and written (Q13). And it returns to Q1.

  In Q14 of FIG. 17, when abnormality occurrence information is input from the monitoring terminal 3 of the elevator 2 to the telephone line communication unit 54 via the communication line 4, this abnormality occurrence information is stored in the monitoring / diagnosis / maintenance inspection data memory 67. The result is additionally written as the monitoring result 67a in the area of the monitoring result of the corresponding elevator (Q15). Then, whether or not an abnormality in the abnormality occurrence information needs to be handled by the operator 23 such as a confinement accident is automatically determined by a predetermined abnormality type (Q16).

  When the monitoring staff (operator) 23 needs to respond, the telephone line 61 connects the telephone line via the communication line 4 to the monitoring terminal 3 that is the transmission source of the abnormality occurrence information (Q17). As a result, the operator 23 of the monitoring center 5 has a conversation with the user of the elevator 2 confined in the car by using the interphone composed of the telephone terminal 61 and the microphone 22 and the speaker 23 in the car 18 of the elevator 2. Can give appropriate instructions.

  Furthermore, when the abnormality in the received abnormality occurrence information is below a level that requires a predetermined maintenance staff 7 dispatch (Q18), the process returns to Q1.

  When the level that requires the dispatch of the maintenance staff 7 is exceeded, the maintenance staff set to “moving” in the current status in the maintenance staff database 66, that is, the maintenance staff 7 not in the maintenance inspection work is extracted (Q19). . Then, a call is automatically made to the extracted portable terminal 8 of each maintenance staff 7. When the maintenance staff 7 responds, the operator 23 inquires the maintenance staff 7 about the current position (Q20). When the address of the current position is notified from the maintenance staff 7 (Q21), the operator 23 inputs the address from the input unit 60, and the map shown in FIG. For example, the current position of the maintenance staff 7 who is not working at the present time is displayed in a blinking manner in FIG.

  The operator 23 actually goes to rescue from among the maintenance personnel 7 who are not “working” at the current position indicated by the blinking “O” mark indicating the occurrence of an abnormality and the blinking “X” mark. When one or a plurality of maintenance personnel 7 are designated by the input unit 60 (Q23), only the elevator position indicated by the “◯” mark to be rescued and the maintenance personnel position indicated by the “×” mark of the selected maintenance personnel 7 Edit the map where is displayed. Then, the information is transmitted to the portable terminal 8 of the selected maintenance worker 7 together with the position information of the elevator 2 and the instruction to perform the rescue operation (Q24).

  Therefore, the selected maintenance staff 7 refers to the position of the rescue target elevator 2 marked “O” and the current position of the maintenance staff 7 marked “X” on the display screen of his portable terminal 8. Then, go to rescue 2 elevator.

In the elevator remote monitoring system configured as described above, each component that is relatively frequently replaced in each monitored elevator 2 is stored in the component database 63 of the storage unit 62 of the monitoring device 6 of the monitoring center 5. A diagnosis execution pattern 69 is stored. The diagnosis execution pattern 69 is created by using a failure occurrence rate characteristic 70 indicating the relationship between the elapsed time A from the start of use of each component and the failure occurrence rate B. That is, in the initial period (A = A _{1 to} A ₂ ) and the final period (A = A _{3 to} A ₄ ), which are the elapsed time regions in which the failure occurrence rate B is high in the average life time of this part, the diagnosis execution period T Is set short (T = T _A , T = T _C ), and the execution period T is set long (T = T) in the middle period (A = A _{2 to} A ₃ ), which is an elapsed time region where the failure rate B is low. _B ) The diagnosis schedule 46 is obtained by setting an actual date for parts replacement in the diagnosis execution pattern 69.

  As the parts of each elevator 2 are replaced, the diagnosis schedule 46 corresponding to the failure rate characteristic 70 of the corresponding part is automatically set along with the replacement. Then, actual diagnosis is performed according to the diagnosis schedule 46. The diagnosis result is transmitted to the monitoring device 6 each time and stored in the monitoring / diagnosis / maintenance inspection data memory 67.

  During the period when the failure occurrence rate is high, the actual diagnosis cycle for the elevator 2 is short, and during the period when the failure occurrence rate is low, the diagnosis cycle is long. Therefore, it is possible to reduce the number of communications of the monitoring center by performing a diagnosis frequently even though the failure occurrence rate cannot be detected in a short time even though the failure occurrence rate is high and the failure occurrence rate is low. A situation in which the processing load is unnecessarily occupied and an increase in processing load is prevented, and automatic diagnosis for the monitored elevator 2 can be efficiently performed.

  In addition, this invention is not limited to embodiment mentioned above. For example, it goes without saying that the elevator may be an escalator or the like in addition to the elevator.

  Furthermore, parts replacement in each elevator 2 is performed not only during maintenance inspections that are regularly performed by the maintenance staff 7, but also by the maintenance terminal 7 visiting the corresponding elevator 2 in response to the occurrence of an abnormality in the elevator 2. It is also possible to implement. Even in this case, the maintenance staff 7 needs to immediately report parts replacement to the monitoring center 5.
