FIG. 2 is a diagram showing a hardware configuration example of the center device 2, and is a diagram illustrating a computer configuration.

The center device 2 has a controller 101, an input device 110, and an output device 111. The controller 101 controls each hardware operating inside the center device 2. The controller 101 has the following configuration.

The CPU 102 (CPU: Central Processing Unit) is a processing device that expands a program stored in a ROM 104 (ROM: Read only memory) or a storage 105 into a RAM 103 (RAM: Random access memory) and executes an operation. The CPU 102 comprehensively controls each hardware inside the controller 101 by executing a program. The RAM 103 is a volatile memory, which is a work memory when the CPU 102 processes. The RAM 103 temporarily stores necessary data while the CPU 102 calculates and executes the program.

The ROM 104 is a non-volatile memory, and stores the BIOS (Basic Input / Output System) executed by the CPU 102 when the center device 2 is started, and the firmware.

The storage 105 is an auxiliary storage device that stores data non-volatilely, such as a hard disk drive. The storage 105 stores a program executed by the CPU 102 and control data. In this embodiment, a program or database that provides each function described below is introduced and constructed in advance.

The network I / F 106 is an interface board that controls data communication performed with an external device. The network I / F 106 controls communication between the monitoring device 52 and the customer operation terminal 7 via the wide area network 60 and 70.

The input I / F 107 is an interface that controls the input / output of signals to / from the input device 110. The output I / F 108 receives an instruction from the CPU 102 and causes the output device 111 to draw an image.

The input device 110 is, for example, a keyboard or a mouse, and the output device 111 is a flat monitor or a display.

The customer operation terminal 7 and the mobile terminal 9 shown in FIG. 1 include the same configuration as the hardware shown in FIG. 2, but the input device and the output device may be replaced with a touch panel display. Further, the control device 51 and the monitoring device 52 also include the same configuration as the hardware shown in FIG. 2, but some functions may be implemented by an ASIC (application specific integrated circuit) to control the elevator 50. You may add an interface to do this.

FIG. 3 is a block diagram showing a configuration example of the elevator system 500, and is a diagram mainly showing a main configuration of each device. FIG. 3 also shows the configuration of the maintenance work management system 100 included in the elevator system 500. The maintenance work management system 100 has at least a center device 2 and a monitoring device 52. Further, the maintenance work management system 100 may have a configuration including a mobile terminal 9, a control device 51, and a customer operation terminal 7, or may have a configuration including an elevator 50 to be maintained.

The center device 2 includes a control unit 30, a transmission / reception unit 31 (reception unit), a work record registration determination unit 32 (determination unit), a schedule registration unit 33, and a storage unit 34. Each of these parts is realized by the CPU 102 loading a program stored in advance in the storage 105 into the RAM 103, executing the program, and cooperating with each hardware.

The control unit 30 is a functional unit that comprehensively controls the operation in the center device 2, and activates and cooperates with each functional unit in the center device 2 to input data between the functional units. Control the output. The transmission / reception unit 31 is a functional unit that connects to the wide area network 60 and 70 and transmits / receives various data.

The work record registration determination unit 32 is a functional unit that determines whether or not the maintenance work has been performed according to a regular procedure. The work record registration determination unit 32 determines whether or not the work result determination program 34C, which is stored in advance in the storage unit 34, has been executed according to the normal procedure. The schedule registration unit 33 is a functional unit that re-registers work items determined by the work record registration determination unit 32 that have not been performed in the normal procedure to the next schedule. The operations of the work record registration determination unit 32 and the schedule registration unit 33 will be clarified by an explanation using a flowchart described later.

The transmission / reception unit 31 receives the captured data transmitted from the monitoring device 52 and stores it in the storage unit 34 as the captured data 34A. The transmission / reception unit 31 also has a function of transmitting a work report to the customer operation terminal 7 by e-mail.

The storage unit 34 is a storage area for storing data, and stores captured data 34A, inspection schedule 34B, work record determination program 34C, pre-confirmation work record data 34D, and confirmed work record data 34E.

The captured data 34A is data in which the operating states of each device of the elevator 50 captured (collected) by the monitoring device 52 during maintenance and inspection are stored in chronological order.

The inspection schedule 34B is data of the inspection work plan of the elevator 50, and is patrol schedule data for managing and storing each item (implementation item described later) performed as maintenance work and the inspection execution date and time. In the inspection schedule 34B, it is common for a specific operator to manually register the work contents for the next month in advance, but a schedule generated by another planning system (not shown) is stored in the storage unit 34 as the inspection schedule 34B. It may be registered.

The work record determination program 34C is a sub-module (determination program) for determining whether the maintenance work has been performed correctly, and is activated by the work record registration determination unit 32. The work performance determination program 34C is provided in advance for each maintenance work implementation item. Although one work record determination program 34C is shown in FIG. 3, a work record determination program 34C is provided for each action item performed as maintenance work. The work record registration determination unit 32 selects the work record determination program 34C to be activated based on the action items registered in the inspection schedule 34B. The work performance determination program 34C inputs the captured data 34A, determines whether or not the inspection work has been performed normally, and outputs the determination result. In the present embodiment, it is assumed that the work performance determination program 34C is hard-coded with the condition logic for performing this determination. As described above, the work performance determination program 34C is provided in advance for each implementation item as determination information for determining whether or not each implementation item to be performed in the maintenance work is correctly performed.

The pre-confirmation work result data 34D is data that summarizes various data such as the implementation and non-execution status of each item to be performed in the maintenance work, and the value measured during the maintenance work. The pre-confirmation work record data 34D includes data input by the worker using the mobile terminal 9 during maintenance work and measured values obtained by the monitoring device 52, and includes data obtained from the mobile terminal 9, the monitoring device 52, and a wide area. It is transmitted to the center device 2 via the line network 60.

The finalized work record data 34E is the main registration of the pre-fixed work record data 34D, and in the present embodiment, the final registration is performed by executing the flowchart of FIG. 7 described later.

The monitoring device 52 includes a control unit 21, a transmission / reception unit 22 (transmission unit), an operation state acquisition unit 23, an acquisition data transmission control unit 24, a floor height measurement operation command unit 25, a floor height data calculation unit 26, and a storage unit 27. ..

The control unit 21 and the transmission / reception unit 22 have the same functions as the control unit 30 and the transmission / reception unit 31 in the center device 2. The operation state acquisition unit 23, the acquisition data transmission control unit 24, the floor height measurement operation command unit 25, and the floor height data calculation unit 26 are each functional unit activated and executed by the control unit 21. The storage unit 27 is a storage area for storing data, and stores captured data 27A and floor height data 27B.

The operation state capturing unit 23 captures (collects) the operation of each device in the elevator 50 and the operation of the control device 51 one by one, and performs a process of registering the operation in the captured data 27A of the storage unit 27. The captured data transmission control unit 24 performs a process of transmitting the captured data stored in the captured data 27A to the storage unit 34 of the center device 2 one by one via the transmission / reception unit 22. That is, the same data is always stored in the captured data 34A of the center device 2 and the captured data 27A of the monitoring device 52. If the captured data 27A also includes data during normal operation, the amount of data will be enormous. In this case, the captured data transmission control unit 24 may be implemented to transmit the captured data one by one in real time only during maintenance work (only when the maintenance SW28B is in the ON state).

The elevator 50 includes a main power supply 28A, a maintenance SW28B (SW: switch), and a stop SW28C, and FIG. 3 shows a rotary encoder 28D as an example of the equipment of the elevator 50. The main power supply 28A, maintenance SW28B, and stop SW28C may be provided on the control device 51 side depending on the configuration.

The main power supply 28A is a power circuit breaker (FFB) that switches on / off the power power supply of the elevator 50. The maintenance SW28B is a switch that the maintenance worker turns on when starting the maintenance work of the elevator 50. The maintenance SW28B is generally installed in a locked box under the operation panel in the car and can be operated only by an operator. When this switch is turned on, the elevator 50 switches to the maintenance operation mode and does not accept the operation of the push button installed at the landing. The stop SW28C is a safety device that prevents the car of the elevator 50 from inadvertently operating. The stop SW28C is installed in the same box as the maintenance SW28B, and is always turned on when parts are replaced or adjusted for the safety of the operator. The rotary encoder 28D is installed in the motor of the elevator 50 and is a device for detecting the position and speed of the car. Here, the work of replacing the rotary encoder 28D will be described as an example.

The floor height measurement operation command unit 25 of the monitoring device 52 is a functional unit that gives an execution instruction for the floor height measurement operation that must be performed after the rotary encoder is replaced. The floor height measurement operation command unit 25 receives an instruction telegram from the maintenance worker's mobile terminal 9 via wireless communication, and starts executing the floor height measurement operation. The floor height measurement operation is a dedicated operation that redefines the position where the car stops, and is a position detector installed in the tower of the elevator 50 when operating at low speed from the top floor to the bottom floor. Is calculated and determined by the floor height data calculation unit 26 based on the detection position and the like. The value determined by the floor height data calculation unit 26 is stored in the storage unit 27 as the floor height data 27B. A known technique may be used for the operation of the floor height measurement operation command unit 25 and the floor height data calculation unit 26.

In the case of an implementation in which the floor height measurement operation is started by a predetermined operation on the push button installed at the landing, the floor designation button in the car, or the door open / close button, the elevator user accidentally performs the operation. There is a possibility of going. Therefore, in the present embodiment, it is assumed that the floor height measurement operation is started by the mobile terminal 9 held by a professional worker.

FIG. 4 is a flowchart showing a rotary encoder replacement work as an example of maintenance work performed by an operator. Further, FIG. 5 is a sequence diagram showing an output signal of the device of the elevator 50 when the maintenance work of FIG. 4 is performed. The same number as the code of the processing step shown in FIG. 4 is also attached to the sequence diagram of FIG.

It is assumed that the flowchart of FIG. 4 shows the correct maintenance work contents without any omissions or deficiencies. In addition, the worker has taken the manual according to the flowchart shown in FIG. 4 into the mobile terminal 9 in advance or brought it on paper, and the worker shall perform the work while referring to this.

First, FIG. 5 will be described. FIG. 5 depicts the work performed between 10:00 and 11:00. The vertical axis shows the operating state of each device, and the horizontal axis is a time series.

In FIG. 5, the car position indicates the floor position (1F to 3F) of the car. The power supply indicates an on / off state of the main power supply 28A. The maintenance SW indicates an ON / OFF state of the maintenance SW 28B. The stop SW indicates an on / off state of the stop SW 28C. The floor height measurement operation indicates the operation execution state on and off. The floor height data T8a, T8b, and T8c indicate changes in the floor height data 27B. While the power is turned off, each device holds the state immediately before the power is turned off.

The flowchart of FIG. 4 will be described. When the operator starts the maintenance work, the maintenance SW28B in the car is first turned on to switch to the inspection mode (S001). At that time, the signal of the maintenance SW in FIG. 5 becomes an output indicating from off to on.

Next, the worker moves to the top floor in a car to move to the elevator machine room on the roof (S002). At that time, the signal at the car position in FIG. 5 becomes an output indicating 1F to 3F in conjunction with the movement of the car.

The operator turns on the stop SW28C for the purpose of safety (S003). At that time, the stop SW signal in FIG. 5 becomes an output indicating from off to on.

Next, the worker enters the elevator machine room and turns off the main power supply 28A of the elevator 50 in consideration of safety such as prevention of electric shock when replacing parts (S004). At that time, the signal output of the power supply shown in FIG. 5 changes from on to off. As a result, all the devices are in an invariant state until the main power supply 28A is turned on.

Next, the operator replaces the rotary encoder 28D. The procedure for the replacement work is determined in advance, and the estimated time required for the replacement work is determined for each elevator model and device to be replaced. In the description here, it is assumed that it takes at least 30 minutes no matter how smart the worker works.

Then, when the replacement work is completed, the worker turns on the main power supply 28A of the elevator 50 (S101). At that time, the power signal of FIG. 5 becomes an output indicating ON.

Next, the operator turns off the stop SW28C in the car in order to return the elevator 50 (S102). At that time, the stop SW signal in FIG. 5 becomes an output indicating from on to off.

Next, the operator operates the mobile terminal 9 and instructs the elevator 50 to perform the floor height measurement operation (S103). After replacing the rotary encoder 28D of the elevator 50, it is necessary for the floor height data calculation unit 26 to recalculate the floor height data 27B. If this is not done, the elevator 50 may detect a failure and recover. Can not. Therefore, after the work, the floor height measurement operation is carried out. At that time, the floor height measurement operation of FIG. 5 is switched to the on state indicating that the operation is being executed.

Since the floor height measurement operation is a measurement method in which the vehicle operates at a low speed from the top floor to the bottom floor, the car position shown in FIG. 5 shows a gradual signal change from the 3rd floor to the 1st floor. Further, the floor height data 27B is temporarily reset to 0 (zero) immediately after the start of the floor height measurement operation, and the data is set again after the measurement operation is completed. Therefore, the floor height data T8a, T8b, and T8c of FIG. 5 show 0 immediately after the execution of the floor height measurement operation, and then show each value in order from the floor where the measurement is completed.

Next, the operator performs a reciprocating operation between the top floor and the bottom floor in order to confirm that the elevator 50 has returned to normal (S104). At that time, the car position in FIG. 5 is a signal output indicating that the car has reciprocated between the 1st floor and the 3rd floor. Here, the reciprocating operation is performed twice.

Finally, the operator turns off the maintenance SW28B (S105), and the rotary encoder replacement work is completed. At that time, the maintenance SW in FIG. 5 becomes a signal indicating from on to off. If there are other inspections and maintenance, the worker will continue the maintenance work.

The operating state capturing unit 23 of the monitoring device 52 inputs this series of operation signals from the control device 51 and outputs a log as captured data 27A. Further, the captured data transmission control unit 24 operates in parallel with the operating state capture unit 23 to transmit the captured data 27A to the center device 2. As a result, the center device 2 can obtain the captured data 34A, which is the same data as the captured data 27A.

FIG. 6 is an example of captured data 27A and 34A. The captured data 27A and 34A include date and time information of the implementation date (year / month / day) and time (hour / minute / second), identification information (“C0032” in the figure) that uniquely indicates the owner (customer) of the elevator 50, and work. It has a data structure in which identification information (“G001” in the figure) indicating the number of the elevator that has been performed and the operation content are recorded as one record. Hereinafter, the identification information uniquely indicating the owner (customer) of the elevator 50 is referred to as a customer ID, and the identification information indicating the elevator unit is referred to as a customer unit ID.

FIG. 7 is a flowchart showing the operation by the center device 2. In the present embodiment, the determination process is performed by the work record registration determination unit 32 of the center device 2, but the monitoring device 52 or the mobile terminal 9 may perform this process. The flowchart of FIG. 7 will be described as determining whether or not the work of the operator described with reference to FIGS. 4 and 5 has been performed correctly.

When the worker registers the work record on the mobile terminal 9 after the inspection is completed, the work record data is transmitted from the mobile terminal 9 using this as an opportunity. The work record data includes work report data manually input by the worker. When the transmission / reception unit 31 of the center device 2 receives the work record data, it stores it in the storage unit 34 as the pre-determination work record data 34D. The work record registration determination unit 32 waits until this registration is performed (S201: No loop), and when the registration is performed (S201: Yes), starts processing.

The work record registration determination unit 32 acquires the captured data 34A from the storage unit 34, and extracts the date / time information, the customer ID, and the customer machine ID from the captured data 34A. Then, the work record registration determination unit 32 refers to the inspection schedule 34B and acquires the schedule ID and the action item ID using the extracted date and time information, the customer ID, and the customer unit ID as search keys.

FIG. 8 is a diagram showing an example of the inspection schedule 34B. The inspection schedule 34B is data in which a schedule ID, an implementation date (including a scheduled implementation date), a worker ID (including a scheduled person in charge), a customer ID, a customer machine ID, and one or more implementation item IDs are set. It is composed. The action item ID is information that uniquely identifies the specific contents (implementation items) of inspection and maintenance. The work record registration determination unit 32 acquires the corresponding schedule ID from the inspection schedule 34B and also acquires the action item ID based on the date / time information, the customer ID, and the customer unit ID described in the captured data 34A. Here, it is assumed that the schedule ID: S0452 is acquired, and the action item IDs: Z0078 (rotary encoder replacement) and Z0029 (brake overhaul inspection) are acquired.

The work record registration determination unit 32 activates the work record determination program 34C associated with the acquired action item ID. In the present embodiment, the association between the action item ID and the work record determination program 34C is performed by the file name of the work record determination program 34C. That is, the action item ID is included in the file name of the work performance determination program 34C and stored in the storage unit 34. Then, the work record registration determination unit 32 starts the work record determination program 34C that includes the action item ID acquired in step S202 in the file name. In addition to this, there are various mapping methods such as using a database.

The following steps S301 to S308 are processes when the work record registration determination unit 32 executes the work record determination program 34C associated with the work item ID: Z0078 (rotary encoder replacement).

The work record registration determination unit 32 extracts the operating state of the device of the elevator 50 during the inspection time zone from the captured data 34A (S302). Here, it is assumed that the data shown in FIG. 6 is extracted. The work record registration determination unit 32 determines S302 to S306 based on the captured data 34A. S302 determines whether the maintenance SW signal is on. S303 determines whether the state in which the stop SW is on continues for 30 minutes or more. S304 determines whether the floor height measurement operation is started after the stop SW is turned off. S305 determines whether or not there is a state change (after 0, then reset) of the floor height data T8a, T8b, and T8c. After resetting the floor height data, S306 determines whether the car position has reciprocated between the top floor and the bottom floor. The determination operations of S302 to S306 are merely examples. If the item is an action item other than the rotary encoder replacement, the work result determination program 34C is processed according to the action item, and naturally the determination process is different from that of S302 to S306.

If even one of the determinations in S302 to S306 is not performed correctly (at least one of the determinations in S302 to S306 is No), the work record registration determination unit 32 does not determine the pre-confirmation work record data 34D. .. Then, the work result registration determination unit 32 activates the schedule registration unit 33, and the schedule registration unit 33 performs the planning process of the next schedule (S308). The processing of the schedule registration unit 33 will be described later with reference to FIG. On the other hand, in the determination of S302 to S306, when all the operations are correctly performed (all the determinations of S302 to S306 are Yes), the work record registration determination unit 32 uses the pre-confirmation work record data 34D as the confirmed work record data. This is officially registered in 34E (S307).

When the operation by the work record determination program 34C is completed, the work record registration determination unit 32 determines whether all the action item IDs acquired in S202 have been processed (S210). If there is an unprocessed action item ID (S211: No), the process is returned to S203 to perform a determination process for the unprocessed action item ID. In this example, the operation for the action item of Z0029 (inspection of brake overhaul) is continuously performed.

When the determination process is completed for all the action item IDs (S210: Yes), the work record registration determination unit 32 derives an evaluation value according to the determination result (S211). This process will be described later with reference to FIG. The work record registration determination unit 32 then sends a work report mail to the customer of the elevator (S212). The content of the e-mail sent here will be a part or all of the work record data confirmed in S307, or a rescheduling notification.

FIG. 9 is a diagram showing an example of a data structure including the evaluation value derived in step S211. In the present embodiment, if any of the judgment results for each action item ID (the results for each item in the figure and the judgment results for S302 to S306 above) is inadequate, the maintenance work results for the inspection and maintenance are non-conforming. Treat as (NG). On the other hand, if all the results for each item are good, the maintenance work results for the inspection and maintenance are treated as conformity (OK).

Further, the work record registration determination unit 32 derives the evaluation rank based on the result for each item and stores it in the storage unit 34. The evaluation rank is from A rank to C rank in this embodiment. In the example of FIG. 9, if all the results for each item are conforming results, the rank is A, and if there is even one nonconforming result, the rank is C. In addition to this, all maintenance items such as equipment replacement and cleaning are conformity results, but if only one of the inspection items (visual confirmation and operation confirmation) is nonconformity, it will be ranked as B rank. good.

It should be noted that what kind of action item is inadequate to make the maintenance work result non-conforming is appropriately adjusted and set. In addition, what kind of action items should be ranked when there is a defect is appropriately adjusted and set.

Since the evaluation rank shown in FIG. 9 and the person in charge ID shown in FIG. 8 are linked via the schedule ID and stored in the storage unit 34, it is possible to aggregate the evaluation rank for each person in charge. .. Therefore, it is possible to extract workers who need re-education, which can be useful for improving the quality of work.

FIG. 10 is a diagram illustrating an embodiment when reschedule a work item that has a defect. FIG. 10 illustrates a case in which there was a defect in the door-related maintenance (execution item ID: Z0156) carried out on February 15, 2018. The schedule registration unit 33 reschedules the existing schedule scheduled to be implemented next month for the relevant customer and the relevant elevator unit by adding items for door-related maintenance that have been defective. Further, since the work time is increased by reschedule, the schedule registration unit 33 adjusts either or both of the start time and the end time. The work record registration determination unit 32 attaches the result of such reschedule to the work report mail and sends it to the customer.

In the present embodiment, the rotary encoder replacement work has been described as an example, but it can be applied to the replacement of other devices and the inspection work that does not require replacement by arbitrarily creating the determination conditions.

In the present embodiment, for example, as shown in S304, S305, and S306 of FIG. 7, the order of work can be defined in the determination conditions. It is also possible to define only whether or not the corresponding item has been performed regardless of the work order. Further, as shown in S303 of FIG. 7, it is possible to define whether the time required for the work is equal to or longer than the specified time (or within the specified time) and evaluate it. Further, in the case of work in which an alternative method other than the formal method exists, it is possible to determine whether either the formal method or the alternative method has been performed. In addition to these, by coding the work performance determination program 34C as needed, it is possible to perform a somewhat complicated determination process.

By switching the program (judgment information) used for the judgment processing for each execution item performed in the maintenance work as in the present embodiment, it is possible to make a more specific judgment for each execution item instead of a uniform judgment. can.

In the above embodiment, it is assumed that the operation start command is output from the mobile terminal 9 and the floor height measurement operation is started according to the output. In addition to this, the mobile terminal 9 may perform some or all of the device operations such as the maintenance SW on / off operation, the car movement operation, the stop SW on / off operation, and the main power off. .. The communication between the mobile terminal 9 and the monitoring device 52 may be either wired or wireless. Further, the communication between the two may be either encrypted communication or unencrypted communication, but from the viewpoint of security, it is better to use encrypted communication that can be deciphered by both the mobile terminal 9 and the monitoring device 52. Is preferable. As in the present embodiment, by performing some or all of the implementation items in accordance with the command from the mobile terminal 9, access is restricted only from the control operation device (mobile terminal) owned by the maintenance worker. be able to. That is, it is possible to eliminate a physical operation caused by an outsider's intention or error.

The data structure and operation described in the above embodiment are merely examples, and are not limited thereto.

By determining whether the captured data indicating the operation of each device corresponds to the work of the maintenance worker when the corresponding maintenance work is performed correctly as in the present embodiment, an objective judgment can be made. Evaluation can be performed. Further, for example, even in the case of parts replacement, as shown in S303 of FIG. 7, the actual working time can be measured based on the output signal of the peripheral device, and it is possible to determine and evaluate whether or not the actual work time has been performed correctly.

As described above, according to this embodiment, it is possible to evaluate whether the maintenance work is performed correctly.

The present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the described configurations. Further, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. Further, it is possible to add / delete / replace a part of the configuration of each embodiment with another configuration. Further, each of the above configurations, functions, processing units, processing means and the like may be realized by hardware by designing a part or all of them by, for example, an integrated circuit. Further, each of the above configurations, functions, and the like may be realized by software by the processor interpreting and executing a program that realizes each function. Information such as programs, tables, and files that realize each function can be placed in a memory, a hard disk, a recording device such as an SSD (Solid State Drive), or a recording medium such as an IC card, an SD card, or a DVD.
