[0009] Hereinafter, embodiments of an elevator control device and an elevator control method according to the present invention will be described in detail with reference to the drawings. Note that the same components in each embodiment are designated by the same reference numerals, and duplicated descriptions of the same components will be omitted.

[0010] First Embodiment Figure 1 is a schematic diagram of an elevator system having an elevator control device according to a first embodiment. The elevator system 100 shown in this figure includes a car 2, a drive mechanism 3, a display unit 4, an external communication device 5, a maintenance switch 6, and an elevator control device 7. The elevator control device 7 includes an inspection information management unit 71 that manages warning information to notify the user that a statutory inspection of the elevator system 100 has not been carried out. Each component of the elevator system 100 will be described below.

[0011] <Riding basket 2> The car 2 travels within a running path provided in the building. The car 2 is equipped with a car door 2a, and by opening the car door 2a in an elevator hall facing the running path where the car 2 arrives, passengers can freely get on and off the car 2.

[0012] <Drive mechanism 3> The drive mechanism 3 includes, for example, a door opening / closing device for opening and closing the car door 2a. Although not shown in the drawings, the drive mechanism 3 also includes, in addition to the door opening / closing device, a hoist for a main rope connected to the passenger car 2.

[0013] <Display section 4> The display unit 4 is disposed inside the car 2 and displays various contents such as the destination floor of the car 2. Although not shown here, the display unit 4 may also be provided in the elevator hall where the car 2 arrives. Such a display unit 4 also functions as an output unit that outputs attention-calling information when an inspection item is required to be inspected among the inspection items in the statutory inspection of the elevator device 100.

[0014] <External Communication Device 5> The external communication device 5 is arranged inside the car 2, and is equipment for making calls with the outside of the car 2. Such an external communication device 5 is, for example, a parent-child interphone. In the parent-child interphone, an interphone slave 5a is arranged inside the car 2 as the external communication device 5, and is capable of making calls with an interphone master 5b arranged outside the car 2, for example, in a management center.

[0015] <Maintenance switch 6> The maintenance switch 6 is a switch for slowing down the traveling speed of the elevator car 2 of the elevator system 100 to facilitate inspection work when inspecting the elevator system 100. It is also a switch for stopping operation. This maintenance switch 6 is operated only by the worker inspecting the elevator system 100, and is installed, for example, inside the elevator car 2.

[0016] <Elevator control device 7> The elevator control device 7 is configured by a calculator installed in a control panel. The calculator is hardware used as a so-called computer. The calculator may include a CPU (Central Processing Unit), RAM (Random Access Memory), and a non-volatile storage unit such as a ROM (Read Only Memory) or HDD (Hard Disk Drive), and may also include a network interface to enable communication with an external terminal device 10. The elevator control device 7 configured by such a computer includes an operation control unit 70 and an inspection information management unit 71.

[0017] The external terminal device 10 may be, for example, a portable terminal as a maintenance tool carried by a maintenance worker of the elevator device 100, or a terminal device installed in a control center of the elevator device 100. For example, an instruction to temporarily erase the display of the warning information displayed on the display unit 4 is input to this terminal device 10, and the input instruction is transmitted to the elevator control device 7. It is preferable that the input of the instruction to temporarily erase is an operation that requires, for example, input of a code.

[0018] -Operation Control Unit 70- The operation control unit 70 stores a control program related to the operation of the elevator apparatus, including the travel of the car 2 and the opening and closing of the car doors 2a, in a nonvolatile storage unit, and controls the operation of the elevator apparatus 100 by executing processing based on the stored control program. The operation control unit 70 also stops the operation of the elevator apparatus by operating the maintenance switch 6, for example.

[0019] -Test Information Management Department 71- The inspection information management unit 71 stores a management program for managing the output of warning information to the display unit 4 in a non-volatile storage unit, and executes processing based on the stored management program. Here, the warning information is information for notifying users of the elevator device 100 that an inspection has not been carried out when there is an item that has not been inspected among the inspection items that are required to be inspected periodically for the elevator device 100.

[0020] The test information management unit 71 has functional units that execute a management program for managing the output of warning information, including a test item storage unit 71a, a test completion determination unit 71b, a non-test period count unit 71c, a temporary deletion operation determination unit 71d, a count value subtraction processing unit 71e, a warning necessity determination unit 71f, a warning information output unit 71g, and a temporary deletion implementation status determination unit 71h.

[0021] Of these, the unexecuted test period counting unit 71c, the warning necessity determining unit 71f, and the warning information output unit 71g constitute an output processing unit that outputs unexecuted test warning information to the output unit, which is the display unit 4. In addition, the temporary deletion operation determining unit 71d, the count value subtraction processing unit 71e, and the temporary deletion implementation status determining unit 71h constitute a temporary deletion processing unit that causes the output processing unit to temporarily delete the output of the warning information. Each component of the test information management unit 71 will be described below.

[0022] [Test Item Storage Unit 71a] The inspection item storage unit 71a is a part that stores information on important inspection items that require periodic inspection for the elevator device 100. The inspection item storage unit 71a stores an inspection procedure and an inspection completion determination condition for each important inspection item in association with each other.

[0023] [Inspection completion determination unit 71b] The inspection completion determination unit 71b determines whether or not the inspection of each important inspection item stored in the inspection item storage unit 71a has been completed. The inspection completion determination unit 71b performs this determination based on whether or not the inspection completion determination conditions stored in the inspection item storage unit 71a have been satisfied.

[0024] [Untested Period Counting Unit 71c] The non-examination period counting unit 71c is a part that constitutes the output processing unit, and counts the non-examination period during which the examination of each important examination item stored in the examination item storage unit 71a has not been performed.

[0025] FIG. 2 is a process diagram illustrating an inspection schedule for an elevator system. As shown in FIG. 2, statutory inspections E1, E2, ... and periodic inspections C1, C2, C3 are performed as inspections for the maintenance and management of an elevator system 100. The statutory inspections E1, E2, ... are required to be performed every year. The periodic inspections C1, C2, C3 are performed between the annual statutory inspections E1, E2, ... and are performed at intervals independently set by the elevator system maintenance and management company. In the illustrated example, the schedule is such that periodic inspections C1, C2, C3 are performed every three months, but the intervals between periodic inspections may be set at any interval.

[0026] For these statutory inspections E1, E2, ... and periodic inspections C1, C2, C3, scheduled inspection periods are set, so for example, if the scheduled period for statutory inspections E1, E2, ... is the month of August each year, then the statutory inspections should be carried out during that month. In this case, the scheduled periods for periodic inspections C1, C2, C3 are November, February, and May.

[0027] Returning to FIG. 1, the no-inspection-period counting unit 71c counts, for each important inspection item, the time that has elapsed since the statutory inspection was actually carried out as the no-inspection period.

[0028] [Temporary deletion operation determination unit 71d] The temporary erasure operation determination unit 71d is a part that constitutes the temporary erasure processing unit. The temporary erasure operation determination unit 71d determines whether or not an instruction to erase the output of the attention-calling information has been received from the terminal device 10, and if it determines that an instruction has been received, it instructs the attention-calling information output unit 71g to erase the output of the attention-calling information. The procedure for determination by this temporary erasure operation determination unit 71d will be described in detail below in the elevator control method.

[0029] [Count value subtraction processing unit 71e] The count value subtraction processing unit 71e is a component of the temporary deletion processing unit. When the temporary deletion operation determination unit 71d determines that an instruction to delete the output of the warning information has been issued, the count value subtraction processing unit 71e performs a process of subtracting the count value counted by the non-inspection period counting unit 71c. In this case, the count value subtraction processing unit 71e has a count value subtraction processing unit that subtracts at least the length of the interval between inspections from the non-inspection period counted by the non-inspection period counting unit 71c. The procedure for the subtraction process by the count value subtraction processing unit 71e will be described in detail below in the elevator control method.

[0030] [Caution necessity determination unit 71f] The warning necessity determination unit 71f is a part that constitutes the output processing unit. The warning necessity determination unit 71f determines whether the uninspected period counted by the uninspected period count unit 71c has reached a predetermined period. Based on this determination, the warning necessity determination unit 71f determines whether a warning is necessary. The determination procedure by this warning necessity determination unit 71f will be described in detail in the elevator control method below.

[0031] [Warning information output unit 71g] The warning information output unit 71g is a part that constitutes the output processing unit. When the warning necessity determination unit 71f determines that the untested period has reached a predetermined period, the warning information output unit 71g outputs and displays warning information on the display unit 4. This predetermined period is a value held by the warning information output unit 71g,

[0032] 3 is a diagram showing an example of a display of unperformed inspection alert information. As shown in this figure, the display unit 4 displays an unperformed inspection item (e.g., item A1) and the period of time for which the inspection has not been performed (one year or more) as unperformed inspection alert information 41. This notifies users of the elevator device 100 that the inspection has not been performed.

[0033] Furthermore, when the inspection completion determination unit 71b determines that the inspection is completed, the warning information output unit 71g erases the warning information that has been output to the display unit 4. The timing of outputting and erasing the warning information by the warning information output unit 71g will be described in detail in the following elevator control method.

[0034] [Temporary deletion execution status determination section 71h] Returning to FIG. 1 , the temporary erasure implementation status determination unit 71h is a component of the temporary erasure processing unit. The temporary erasure implementation status determination unit 71h determines whether the number of times the warning information displayed on the display unit 4 has been temporarily erased is equal to or less than a preset number of times. The temporary erasure implementation status determination unit 71h instructs the warning information output unit 71g to temporarily erase the output of the warning information only when it determines that the number of times is equal to or less than a preset number of times. This number of times is a value held by the temporary erasure implementation status determination unit 71h, and is typically one, but may also be a value changed by a value input from the terminal device 10, for example. The determination by the temporary erasure implementation status determination unit 71h is made based on the determination information from the temporary erasure work determination unit 71d. The timing of the determination by the temporary erasure implementation status determination unit 71h will be described in detail below in the elevator control method.

[0035] <Elevator control method> Next, an elevator control method implemented by the elevator control device 7 of the elevator system 100 described above will be described.

[0036] Fig. 4 is a flowchart showing an elevator control method according to the first embodiment. The procedure shown in this flowchart is a procedure for controlling the output of attention-calling information to the display unit 4 in accordance with the attention-calling information management program possessed by the inspection information management unit 71 described using Fig. 1. Below, the procedure of the elevator control method will be described along the flowchart of Fig. 4 with reference to Figs. 1 to 3.

[0037] [Step S101] In step S101, the warning necessity determination unit 71f determines whether the count value of the non-test period counted by the non-test period count unit 71c has reached a predetermined value. The warning necessity determination unit 71f performs this determination individually for all test items.

[0038] As explained above with reference to FIG. 2, the schedule for the mandatory inspections E1, E2, ... is set for every year, with a scheduled implementation period of one month. Therefore, the warning necessity determination unit 71f holds 13 months, which includes the scheduled implementation period of the two mandatory inspections, as the predetermined period, and makes this determination using the count value corresponding to this predetermined period (13 months) as the predetermined value. When the count value in the non-inspection period count unit 71c reaches the predetermined value corresponding to 13 months, the warning necessity determination unit 71f determines that the predetermined value has been reached (YES) and proceeds to step S102.

[0039] For example, assume that all items were inspected during the scheduled period (August) for the statutory inspection E1 of last year (year x1 in FIG. 2). In this case, the uninspected period counting unit 71c counts the number of days for all items for which the statutory inspection E1 was performed, with the date of the statutory inspection E1 set to zero. If the inspection of item A1, for example, is incomplete when 13 months have passed since the scheduled period for the statutory inspection E2 of this year (year x2 in FIG. 2) has ended, the warning necessity determining unit 71f determines that the count value for the uninspected period for item A1 has reached the predetermined value (13 months) (YES), and proceeds to step S102.

[0040] On the other hand, if there is no test item whose count value has reached 13 months, the warning necessity determination unit 71f determines that it has not reached that time (NO) and repeats the determination of step S101. Note that the untested period count unit 71c cancels the count value and resets it to zero for items that were tested during the scheduled period for the statutory test E2.

[0041] [Step S102] In step S102, the warning information output unit 71g causes the display unit 4 to display warning information that the test has not been performed. As a result, as shown in Fig. 3, the display unit 4 displays a warning that the test has not been performed due to an omission in the mandatory test E2 for the test item (e.g., item A1) whose count value has reached 13 months.

[0042] By displaying the warning information on the display unit 4, elevator users are notified that an inspection has not been carried out, and the elevator manager is notified that an inspection has not been carried out. This allows the elevator manager to instruct a maintenance worker to carry out an inspection, for example, on the same day or during the next regular inspection.

[0043] [Step S103] In step S103, the alert necessity determination unit 71f determines that the test completion flag has not been detected for the test item (item A1 in this case) for which it was determined in step S101 that the count value of the untested period has reached the predetermined value. In this case, the alert necessity determination unit 71f makes this determination based on information from the test completion determination unit 71b. That is, if the test completion flag for item A has not been set in the test completion determination unit 71b, the alert necessity determination unit 71f determines that the test completion flag has not been detected (YES) and proceeds to step S104.

[0044] On the other hand, if the examination completion determination unit 71b detects that the examination completion flag for item A1 is set, the warning necessity determination unit 71f determines that the examination completion flag has not been detected (NO) and proceeds to step S104a.

[0045] [Step S104a] In step S104a, the warning information output unit 71g erases the display of the warning information indicating that the test has not been performed on the display unit 4. Thereafter, the process ends.

[0046] [Step S104] Meanwhile, in step S104, the temporary erasure work determination unit 71d determines whether or not an instruction to erase the warning information has been received from the terminal device 10. This terminal device 10 is operated by an elevator manager or a maintenance worker, and if it determines that an instruction to erase the warning information has been received from the terminal device 10 (YES), the process proceeds to step S105. On the other hand, if it determines that no instruction has been received (NO), the process returns to step S103, and the warning necessity determination unit 71f repeats the determination of whether or not the inspection completion flag for item A1 has been detected.

[0047] [Step S105] In step S105, the temporary erasure implementation status determination unit 71h determines whether the instruction to erase the warning information in step S104 is an instruction that has been issued the nth (=1)th time or less. The temporary erasure implementation status determination unit 71h makes this determination based on the determination information from the temporary erasure work determination unit 71d, and if it is determined that the instruction is the nth (=1)th time or less (YES), the process proceeds to step S106. On the other hand, if it is determined that the instruction is not the nth (=1)th time or less (NO), the process returns to step S103. This limits the number of times an instruction to erase the warning information is accepted to the preset nth (=1)th time or less, and only if the instruction is the nth (=1)th time or less, the process proceeds to the next step S106.

[0048] [Step S106] In step 106, the warning information output unit 71g erases the display of the warning information indicating that the test has not been performed on the display unit 4. After that, the process proceeds to step S107.

[0049] [Step S107] In step S107, the count value subtraction processing unit 71e performs subtraction processing on the count value of the non-examination period counted by the non-examination period counting unit 71c.

[0050] 2, the periodic inspection C1 will be carried out three months after the statutory inspection E2 of this fiscal year (fiscal year x2). Therefore, the count value subtraction processing unit 71e performs subtraction processing of the count value to erase the warning information until the first periodic inspection C1 is carried out after erasing the output of the warning information, at least until the periodic inspection C1 is completed.

[0051] Specifically, the count value subtraction processing unit 71e performs a process of subtracting at least the length of the interval between inspections from the count value of the period during which no inspection has been performed. The length of the interval between inspections is a value stored in advance by the count value subtraction processing unit 71e, and is assumed to be a value input from the terminal device 10, for example. In the example shown in FIG. 2, the length of the interval between inspections, including statutory inspections and periodic inspections, is three months. Therefore, in order to ensure that the warning information is deleted before the periodic inspection C1 is completed, a process of subtracting four months, which is one month added to three months, from the count value of the period during which no inspection has been performed, is performed.

[0052] In the example of FIG. 2, because the inspection for item A1 was not performed in the statutory inspection E2 in August, warning information is output and displayed on September 1st. In this situation, if an erasure instruction is given on September 1st, the count value subtraction processing unit 71e subtracts four months from the count value of 13 months as of September 1st, setting the count value as of September 1st to approximately nine months. As a result, the warning information is erased until approximately January 1st, four months after September 1st, when the count value becomes approximately 13 months, that is, until the scheduled period for the regular inspection C1 has passed and the scheduled period for the regular inspection C1 ends. The regular inspection C1 is the first inspection to be performed after the output of the warning information is erased in step S106. The scheduled period for the regular inspection C1 is a value previously stored in the count value subtraction processing unit 71e and corresponds to one of the four months subtracted from the count value of the period for which the inspection has not been performed.

[0053] In this situation, if an erasure command is given on October 1st, the count value subtraction processing unit will subtract 4 months from the count value of 14 months as of October 1st, making the count value as of October 1st approximately 10 months. As a result, the warning information will be erased until around January 1st, three months later, when the count value from October 1st will be approximately 13 months, in other words, until the scheduled period for periodic inspection C1 has passed.

[0054] Thereafter, the process proceeds to step S101. Then, in step S101, the state in which the warning information is erased is maintained until the count value for item A1 reaches a predetermined value (13 months), that is, until the grace period C1a for the next periodic inspection C1.

[0055] <Effects of the first embodiment> According to the first embodiment described above, after warning information that an inspection has not been carried out due to an oversight in a statutory inspection is notified to users by displaying it on the elevator display unit 4, the warning information can be temporarily erased from the display unit 4 by an instruction from the terminal device 10 operated by the elevator manager or maintenance worker. This makes it possible to ensure the integrity of the elevator by notifying the elevator manager of the missing inspection through the user without causing excessive anxiety to the user, and also makes it possible to enhance integrity by resuming the output of the warning information.

[0056] Second Embodiment Fig. 5 is a schematic configuration diagram of an elevator system having an elevator control device according to a second embodiment. The elevator system 200 of the second embodiment shown in this figure differs from the elevator system 100 of the first embodiment shown in Fig. 1 in that the inspection information management unit 72 of the elevator control device 7 additionally includes a maintenance work determination unit 71i; the other configurations are the same. Therefore, the configuration of the maintenance work determination unit 71i will be described below.

[0057] <Elevator control device 7> -Inspection Information Management Department 72- [Maintenance work determination section 71i] The maintenance work determination unit 71i is a component of the temporary deletion processing unit and is used as a maintenance work determination unit that determines whether maintenance work has been performed on the elevator apparatus 100. For example, the maintenance work determination unit 71i determines whether maintenance work has been performed based on the on / off state of the maintenance switch 6 provided on the elevator apparatus 200. As described above, the maintenance switch 6 is a switch for stopping the operation of the elevator apparatus and is operated by a maintenance worker when performing an inspection or testing for maintenance management of the elevator apparatus 100. The maintenance work determination unit 71i determines whether maintenance work has been performed on the elevator apparatus 200 based on whether the maintenance switch 6 has been turned on. When the maintenance switch is turned on while the output of the warning information is temporarily turned off (i.e., maintenance work has been performed), the maintenance work determination unit 71i stops the temporary deletion of the output of the warning information and resumes the output of the warning information from the display unit 4. The maintenance work determination unit 71i may also determine that maintenance work has been performed on the elevator apparatus 100 based on a work execution report input by a maintenance worker to the terminal device 10.

[0058] <Elevator control method> Next, an elevator control method implemented by the elevator control device 7 of the elevator system 200 described above will be described.

[0059] Fig. 6 is a flowchart showing an elevator control method according to the second embodiment. The procedure shown in this flowchart is a procedure for controlling the output of warning information to the display unit 4 in accordance with the warning information management program held by the inspection information management unit 72 described with reference to Fig. 5. The flowchart shown in Fig. 6 is obtained by adding steps S108 and S109 to the flowchart showing the elevator control method according to the first embodiment described with reference to Fig. 4 after the subtraction process of the count value is performed in step S107. Therefore, steps S108 and S109 will be described below.

[0060] [Step S108] Step S108 is a step performed after the count value subtraction processing unit 71e subtracts the count value for the untested period in step S107. In step S108, the maintenance work determination unit 71i determines whether the maintenance switch 6 has been turned on (maintenance work has been performed). If the maintenance work determination unit 71i determines that the maintenance switch 6 has been turned on (YES), the process returns to step S102. This stops the temporary deletion of the output of the warning information, and resumes the display of the warning information (see FIG. 3) that the test for item A1 has not been performed.

[0061] On the other hand, if the maintenance work determining unit 71i determines that the maintenance switch 6 is not turned on (NO), it determines that an inspection has not been carried out, and the process proceeds to step S109.

[0062] [Step S109] In step S109, the warning necessity determination unit 71f determines whether the count value of the untested period counted by the untested period count unit 71c has reached a predetermined value. This determination is made on the count value after subtraction for item A for which it was determined in step S101 that the count value of the untested period has reached the predetermined value. If the count value after subtraction has reached 13 months, it is determined that the period has been reached (YES), and the process returns to step S102. This resumes the display of the untested warning information for item A1 (see FIG. 3).

[0063] On the other hand, if the subtracted count value has not reached 13 months, the warning necessity determination unit 71f determines that it has not reached that time (NO) and returns to step S108, where it repeats the determination of whether the maintenance switch has been turned on.

[0064] <Effects of the second embodiment> According to the second embodiment described above, when the maintenance switch is turned on in a state in which the warning information has been temporarily erased, the display of the warning information is resumed, thereby notifying the maintenance worker who turned on the maintenance switch that item A1 has not been inspected. Therefore, in addition to the effects of the first embodiment, it is possible to make the maintenance worker who turned on the maintenance switch aware again that item A1 has not been inspected, and it is possible to further improve the maintainability of the elevator.

[0065] Third Embodiment Fig. 7 is a schematic diagram of an elevator system having an elevator control device according to a third embodiment. The elevator system 300 of the third embodiment shown in this figure differs from the elevator system 100 of the first embodiment shown in Fig. 1 in that the inspection information management unit 73 of the elevator control device 7 is equipped with a temporary deletion period counting unit 71e' instead of the count value subtraction processing unit 71e. Since the other configurations are the same as those of the first embodiment, the configuration of the temporary deletion period counting unit 71e' will be described below.

[0066] <Elevator control device 7> -Inspection Information Management Department 73- [Temporary erasure period counting unit 71e'] The temporary erasure period counting unit 71e' is a part that constitutes the temporary erasure processing unit. When the temporary erasure operation determination unit 71d determines that an instruction to erase the output of the warning information has been issued and the warning information output unit 71g temporarily erases the display of the warning information, the temporary erasure period counting unit 71e' counts the period from the time of erasure as the temporary erasure period.

[0067] <Elevator control method> Next, an elevator control method implemented by the elevator control device 7 of the elevator system 300 described above will be described.

[0068] Fig. 8 is a flowchart showing an elevator control method according to the third embodiment. The procedure shown in this flowchart is a procedure for controlling the output of attention information to the display unit 4 in accordance with the attention information management program held by the inspection information management unit 73 described using Fig. 7. The flowchart shown in Fig. 8 is a flowchart showing the elevator control method according to the first embodiment described using Fig. 4, with step S201 and subsequent steps added instead of step S107. Therefore, the steps following step S201 will be described below.

[0069] [Step S201] Step S201 is a step that occurs after the warning information output unit 71g issues an instruction in step S106 to erase the display of warning information indicating that the test has not yet been performed on the display unit 4. In step S201, the temporary erasure period counting unit 71e' starts counting the period from the time when the warning information display was erased in step S106. This period is counted as the temporary erasure period for the warning information display.

[0070] [Step S202] In step S202, the attention necessity determination unit 71f determines whether the temporary erasure period of the attention information display counted by the temporary erasure period counting unit 71e' has ended. At this time, the attention necessity determination unit 71f determines that the temporary erasure period has ended (YES) if the temporary erasure period counted by the temporary erasure period counting unit 71e' has reached a preset expiration period. This expiration period is set so that the attention information is erased until the first regular inspection C1 that is performed after the output of the attention information is erased, or at least until the regular inspection C1 is completed, and is held in the attention necessity determination unit 71f.

[0071] Specifically, the expiration period is set to at least the length of the interval between inspections. In the example shown in Figure 2, the interval between inspections, including statutory inspections and periodic inspections, is three months. Therefore, in order to ensure that the warning information is deleted before the periodic inspection C1 is completed, the expiration period is set to four months, which is one month longer than the three months.

[0072] If the warning necessity determination unit 71f determines that the temporary deletion period has ended (YES), the process proceeds to step S203. On the other hand, if the warning necessity determination unit 71f determines that the temporary deletion period has not ended (NO), the process proceeds to step S204.

[0073] [Step S203] In step S203, the temporary deletion period counting unit 71e′ resets the count value of the temporary deletion period, and the process returns to step S102. As a result, the display of the untested warning information for item A1 (see FIG. 3) is resumed regardless of the count status of the untested period by the untested period counting unit 71c.

[0074] [Step S204] Meanwhile, in step S204, the alert necessity determination unit 71f determines whether the test completion flag is set for the test item (item A1 in this case) for which it was determined in step S101 that the count value of the non-test period has reached the predetermined value. In this case, the alert necessity determination unit 71f makes this determination based on information from the test completion determination unit 71b. That is, if the test completion flag for item A is set by the test completion determination unit 71b, the alert necessity determination unit 71f determines that the test completion flag is set (YES) and proceeds to step S205.

[0075] On the other hand, if the test completion determination unit 71b cannot detect that the test completion flag for item A1 is set, the warning necessity determination unit 71f determines that the test completion flag has not been detected (NO) and returns to step S202.

[0076] [Step S205] In step S205, the temporary erasure period counting unit 71e' resets the count value of the temporary erasure period, and the process ends.

[0077] <Effects of the third embodiment> According to the third embodiment described above, similarly to the first embodiment, after warning information that an inspection has not been carried out due to an oversight in a statutory inspection is notified to users by displaying it on the elevator display unit 4, the warning information can be temporarily erased from the display unit 4 in response to an instruction from the terminal device 10 operated by the elevator manager or maintenance worker. This makes it possible to ensure the integrity of the elevator by notifying the elevator manager of the missing inspection through the user without causing excessive anxiety to the user, and also makes it possible to enhance integrity by resuming the output of the warning information.

[0078] Fourth Embodiment FIG. 9 is a schematic configuration diagram of an elevator system having an elevator control device according to a fourth embodiment. The elevator system 400 of the fourth embodiment shown in this figure is a modified version of the elevator system 300 of the third embodiment shown in FIG. 7, and has a configuration in which a maintenance work determination unit 71i is added to the inspection information management unit 74 of the elevator control device 7. The other configurations are the same as those of the third embodiment. The maintenance work determination unit 71i is the same as that described in the second embodiment, so a description thereof will be omitted here.

[0079] <Elevator control method> Next, an elevator control method implemented by the elevator control device 7 of the elevator system 400 described above will be described.

[0080] Fig. 10 is a flowchart showing an elevator control method according to the fourth embodiment. The procedure shown in this flowchart is a procedure for controlling the output of attention information to the display unit 4 in accordance with the attention information management program held by the inspection information management unit 74 described using Fig. 9. The flowchart shown in Fig. 10 performs step S204a instead of steps S204 and S205 of the flowchart showing the elevator control method according to the third embodiment described using Fig. 8. Therefore, step S204a will be described below.

[0081] [Step S204a] Step S204a is a step to which the process proceeds when it is determined in step S202 that the temporary erasure period for the warning information display has not ended (NO). In step S204a, the maintenance work determination unit 71i determines whether the maintenance switch 6 has been turned on (whether maintenance work has been performed).

[0082] If the maintenance work determination unit 71i determines that the maintenance switch 6 has been turned on (YES), the process proceeds to step S203. As a result, in step S203, the temporary erasure period counting unit 71e′ resets the count value of the temporary erasure period, and then the process returns to step S102, where the temporary erasure of the output of the warning information is stopped, and the display of the warning information indicating that the inspection for item A1 has not been performed (see FIG. 3) is resumed.

[0083] On the other hand, if the maintenance work determination unit 71i determines that the maintenance switch 6 has not been turned on (NO), the process returns to step S202 and the temporary erasure implementation status determination unit 71h repeats the determination of the end of the temporary erasure period for the warning information display.

[0084] <Effects of the Fourth Embodiment> According to the fourth embodiment described above, when the maintenance switch is turned on in a state in which the warning information has been temporarily erased, the display of the warning information is resumed, thereby notifying the maintenance worker who turned on the maintenance switch that item A1 has not been inspected. Therefore, in addition to the effect of the third embodiment, it is possible to make the maintenance worker who turned on the maintenance switch aware again that item A1 has not been inspected, and it is possible to further improve the maintainability of the elevator.

[0085] The present invention is not limited to the above-described embodiments and modifications, and includes various other modifications. For example, the above-described embodiments have been described in detail to clearly explain the present invention, and are not necessarily limited to those including all of the described configurations. Furthermore, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment, or to add the configuration of another embodiment to the configuration of one embodiment. Furthermore, it is possible to add, delete, or replace part of the configuration of each embodiment with other configurations. [Explanation of symbols]
