  The work information 151a shown in FIG. 7 and the media information 151e shown in FIG. 8 are managed by being associated with each other by an ID.

  Returning to FIG. 6, next, the work instruction generation unit 153 extracts work items from the work information storage unit 151 according to the organization information in which when, where, and the like are determined, and the combination of the worker and the date A work instruction temporary file is generated for each job (S11). In the first embodiment, the organization information includes work date and time (work start date and work finish date), worker ID, work target (property ID, machine ID, work place ID and target equipment ID), ID, total work time And work order. Organization information may be input by the administrator, or may be reflected from an automatically generated organization schedule. The organization information is input as an editing information file separately created using software such as Excel (registered trademark), which has a GUI (Graphical User Interface) in the work instruction file generation unit 152 and is directly input by the administrator. The work instruction file generation unit 152 is input by a method such as being input or being input as a formation information file automatically created by the formation schedule software. The organization information input to the work instruction file generation unit 152 is stored in the work information storage unit 151, for example.

  Next, in the work instruction temporary file generated by the work instruction generation unit 153, the priority setting unit 154 generates a work instruction file by setting the priority and the work time for each work item and each work target. To do (S12). The work instruction file is divided into, for example, a category of a property, a machine, a work place, a target device, and a work item, and priority and work time can be set to each category.

FIG. 9 is a schematic diagram showing an example of a work instruction file according to the first embodiment.
The work instruction file 155a shown in FIG. 9 includes a property column 155b, a priority column, an operation time column 155d, a machine column 155e, and a priority column 155f. Working time (No.) column 155g, Working place column 155h, Priority (place) column 155i, Working time (place) column 155j, Target equipment column 155k, Priority (machine) column 155l, Working time It is table information including (machine) column 155 m, work item column 155 n, priority (term) column 155 o, and work time (term) column 155 p.

The property column 155b stores a property ID which is property identification information for uniquely specifying a property to be a work target such as a building and a hospital. The property has one or more units.
The priority (object) column 155 c stores the priority of the corresponding property.
The working time (object) column 155 d stores the working time for the corresponding property.

The unit array 155e stores a unit ID that is unit identification information for uniquely identifying an elevator to be a work target. Note that the car has one or more work places.
The priority (No.) column 155f stores the priority of the corresponding elevator.
The working time (No.) column 155g stores the working time in the corresponding elevator.

The work place column 155 h stores a place ID which is place identification information for uniquely specifying a place where a work is to be performed, such as a machine room, each floor, and a PIT. The work place has one or more target devices.
The priority (place) column 155i stores the priority of the corresponding work place.
The work time (place) column 155 j stores the work time at the corresponding work place.

The target device row 155k stores a device ID which is device identification information for uniquely identifying a device to be a work target, such as a rope, a brake, and a door. The target device has one or more work items.
The priority (machine) column 1551 stores the priority of the corresponding target device.
The working time (machine) column 155m stores the working time of the corresponding target device.

The work item column 155 n stores IDs of work items such as a rope state check and a rope tension check. The work item has one or more media for instructing work.
The priority (term) column 155o stores the priority of the corresponding work item.
The work time (term) column 155p stores the work time in the corresponding work item.

  Further, the data in the work instruction file 155a are arranged in the order of work from the top in consideration of work paths such as movement paths and switch on / off timings at the time of generation of the work instruction temporary file, and the priority is taken into consideration. If not, work instructions are displayed in order from the top.

  As described above, work objects are classified into categories of property, machine number, work place, and target device. Each category is configured such that the upper category includes one or more lower categories, and the target device which is the lowest category includes one or more work items. Generally, upper categories have more work items than lower categories.

Here, the method of setting the priority will be described in detail.
First, to distinguish between work items that should be performed and work items that can be carried forward among work items, in the work information 151a, the work items that should be performed must have a priority value of 0 and can be carried forward For the work items in question, the priority value is set to 1 or more. When setting the priority value to one or more, for example, the value may be set as follows.
When the work item is carried forward, the value of the priority of the work item to which the number of visits increases is set to 1, for example, it is necessary to visit again before the planned next inspection. The value of the priority of the work item for which the work efficiency is deteriorated, such as increased preparation work at the next work, is set to 2. The priority value of the work item that does not affect the work efficiency at the next work is set to 3.

  Then, the priority setting unit 154 stores the priority of the corresponding work item in the priority (item) column 155 o based on the work information 151 a.

  Next, the priority setting unit 154 sets the value of the priority (machine) column 1551 of the target device from the values stored in the priority (term) column 155o of the work item. For example, when the corresponding target device includes a work item with priority 0, the target device must be checked without fail. Therefore, the priority setting unit 154 sets 0 in the priority (machine) column 155l. Set

  On the other hand, when the corresponding target device does not include the work item of priority 0, the priority setting unit 154 stores the value stored in the priority (term) column 155o of the work item included in the corresponding target device. Is set as the value of the priority (machine) column 155l of the target device. For example, as shown in FIG. 9, “device 3” includes work item 1 (priority (term) = 3), work item 2 (priority (term) = 2), work item 3 (priority When (section) = 2) is included, 7 (= 3 + 2 + 2) is set in the priority (machine) column 1551 of the device 3.

  Similarly, from the value stored in the priority (machine) column 1551 of the corresponding target device, the value of the priority (field) column 155i of the corresponding work place is set, and the priority (place) of the corresponding work place From the values stored in the column 155i, the values in the corresponding machine priority (No.) column 155f are set, and from the values stored in the corresponding machine No. (No) column 155f, the corresponding property priorities The value of the column 155c is set.

Each priority value is compared for each category, and the lower the priority value, the higher the priority is processed. In other words, work items with a priority value of 0 have the highest priority, and the larger the priority value, the lower the degree of necessity. Therefore, the larger the priority value, the easier it is to be excluded later.
Thereby, the comparison of priority can be performed for each category. Also, the priority of the upper category can be automatically set only by setting the priority value to the work item.

Next, the method of setting the working time will be described in detail.
First, based on the work information 151a, the priority setting unit 154 stores the work time of the corresponding work item in the work time (term) column 155p.

  Next, the priority setting unit 154 adds the total value of the working times stored in the working time (section) column 155p of the work item included in the corresponding target device to the working time (machine) column 155m of the corresponding target equipment Store in For example, as shown in FIG. 9, in the "device 1", work item 1 (work time (term) = 0: 05), work item 2 (work time (term) = 0: 10) and work item When 3 (working time (term) = 0: 10) is included, 0: 25 is set in the working time (machine) column 155 m of the device 1.

  Similarly, from the value stored in the working time (machine) column 155m of the corresponding target device, the value of the working time (field) column 155j of the corresponding working place is set, and the working time (place) of the corresponding working place From the values stored in column 155j, the value of working time (No.) column 155g of the corresponding car is set, and from the values stored in the working time (No.) column 155g of the corresponding No. machine, the working time of the corresponding property The value of the column 155d is set.

This makes it possible to calculate how much work time can be reduced when excluding work items or work targets with low priorities.
Moreover, the work time of the upper category can be calculated only by setting the work time of the work item.

In FIG. 9, for convenience of explanation, the work instruction file 155a has been described in a table format, but as in the work instruction file 155q shown in FIG. 10, the work instruction file may be configured in XML. . In that case, the entire work is tagged as <WORK>, the property is <FIELD>, the unit is <CAR>, the work location is <POSITION>, the target device is <TARGET>, and the work item is <CHECKITEM>. Priorities and working times can also be set as attributes of elements.
In FIG. 10, the <CONTENT> tag has an attribute of an instruction type, and is configured to include a combination of a plurality of work instruction media <TITLE>, <TEXT>, <IMG> and <INPUT>.

Next, on the basis of the home screen image displayed on the display unit 111, the display processing unit 124 receives a selection of a display target from the worker in the input reception unit 112, and sequentially displays the work instruction screen image on the display unit 111. Display (S32).

  At this time, when it is necessary to instruct to input the work result as the work instruction, the display processing unit 124 causes the work instruction screen image of the display unit 111 to display the input instruction of the work result, and the input accepting unit 112 , Receives an input of work result from the worker (S33).

  In addition, when it is necessary to instruct to input work evidence as a work instruction, the display processing unit 124 causes the work instruction screen image of the display unit 111 to display the input instruction of the work evidence, and the input reception unit 112 Receive input of work evidence from the worker (S34).

  Then, when the “next” button in the work instruction screen image displayed on display unit 111 is pressed (Yes in S35), display processing unit 124 advances the process to step S36.

  In step S36, the work progress management unit 126 performs work progress management processing. This process will be described later.

  In the work progress management process of step S36, when the work progress management unit 126 determines that the work is completed (Yes in S37), the process proceeds to step S38. If the work progress management unit 126 determines that the work is not completed (No at S37), the process returns to step S32, and the display processing unit 124 causes the display unit 111 to display the work instruction screen image of the next work item. Display.

  In step S38, the portable terminal 110 ends the work instruction display processing unit 120.

When the work of the work item is not completed, “not performed” is displayed in the result column 161 b.
When the work is completed, the worker displays a work list display screen, confirms that there is no work omission, and ends the work.

15 and 16 are flowcharts showing work progress management processing in the work instruction system 100 according to the first embodiment.
First, the work progress management unit 126 manages the presence or absence of the remaining item which is the remaining operation item, and checks whether there is a remaining item (S40). The remaining items are calculated by the difference between the work item described in the work instruction file 155a and the work item whose state has been completed by the work result input processing unit 125. The work progress management unit 126 can manage the remaining items by referring to the display history acquired by the display processing unit 124. If there is a remaining item (Yes in S40), the process proceeds to step S41. If there is no remaining item (No in S40), the process proceeds to step S45.

  In step S41, the work progress management unit 126 confirms the presence or absence of the remaining work time. If there is no remaining work time (No in S41), the process proceeds to step S42. If there is a remaining work time (Yes in S41), the process proceeds to step S48 in FIG.

  In step S42, the work progress management unit 126 checks whether the remaining items of the work instruction file 155a include a work item having a value of 0 in the priority (term) column 155o. If there is a work item in which the value of the priority (arrangement) column 155o is 0 (Yes in S42), the process proceeds to step S43, and if there is no work item with a value of 0 in the priority (arrangement) column 155o (No in S42) In S42, the process proceeds to step S44.

In step S43, the work progress management unit 126 increases the remaining work time because the work item to be performed is not yet performed. At this time, the time to be increased may reflect the total work time of the remaining items in the priority (term) column 155o of 0, or the worker may manually input the result adjusted with the customer. Then, the process returns to step S41.
On the other hand, in step S44, since there is no work item to be performed, the work progress management unit 126 sets the remaining item to "carry forward". Then, the process proceeds to step S47.

  If it is determined in step S40 that there are no remaining items (No in S40), the process proceeds to step S45, and the work progress management unit 126 checks whether there are any work items excluded. If there is a work item excluded (Yes in S45), the process proceeds to step S46. If there is no work item excluded (No in S45), the process proceeds to step S47.

In step S46, the work progress management unit 126 adds the excluded work item to the remaining item.
On the other hand, in step S47, the work progress management unit 126 determines that the work is completed, and instructs the display processing unit 124 to display the work result screen image on the display unit 111, and ends the process.

In step S48 in FIG. 16, the work progress management unit 126 compares the remaining work time with the total work time (necessary work time) of the remaining items, and whether the remaining work time is longer than the total work time of the remaining items Decide whether or not. If the remaining work time is longer than the total work time of the remaining items (Yes in S48), the process proceeds to step S49, and the remaining work time is less than or equal to the total work time of the remaining items (No in S48) Then, the process proceeds to step S50.
In step S49, the work progress management unit 126 determines that the work is not completed, and ends the process.

On the other hand, in step S50, the priority determination unit 127 can not complete the remaining items within the remaining operation time, and thus performs priority determination processing. The method of the priority determination process will be described later.
The work progress management unit 126 excludes, from the remaining items, the work items included in the work items excluded from the priority determination processing or the work objects excluded from the exclusion (S51). By excluding the work item to be excluded, it is possible to reduce the working time for the work item.

  Then, the process returns to step S48, and the work progress management unit 126 compares the remaining work time with the total work time of the remaining items again, and if the remaining work time is larger (Yes in S48) The process proceeds to step S49. On the other hand, if the remaining work time is equal or the remaining work time is shorter (No in S48), the priority determination unit 127 performs the priority determination process again (S50), and the work progress management unit 126 is excluded. Exclude the target work item (S51). Then, the process returns to step S48.

  FIG. 17 is a flowchart showing priority determination processing in the work instruction system 100 according to the first embodiment.

Operations such as elevator maintenance are not independent for each work item, but have a group that enables efficient work. For example, when checking a certain device, if work is performed in the flow of preparation, work item 1, work item 2, work item 3 and post-cleaning, if work item 2 is carried forward, advance preparation, work at the next work Item 2 and post-cleaning work occur, and additional pre-preparation and post-cleaning work may occur to carry out only work item 2, which may result in poor work efficiency.
Therefore, when excluding the remaining items as a result of the priority determination process, it is desirable to exclude them in a unit having a unity. Therefore, in the priority determination process according to the first embodiment, as shown in the work instruction file 155a of FIG. 9, a unit (category) in which a plurality of work items such as a property, a machine, a work place and a target device are grouped. ), The priority determination process is performed.

  First, the priority determination unit 127 determines the value of the priority (object) column 155c of the property of the work instruction file 155a (S60). Then, the priority determination unit 127 determines whether there is a property having a value other than 0 and the highest priority value (the property with the lowest priority), which does not include the work item already performed. To do (S61). If there is such a property (Yes in S61), the priority determination unit 127 ends the process with such a property as an exclusion target. On the other hand, when there is no such property (S61: No), the process proceeds to step S62.

  In step S62, the priority determination unit 127 determines the value of the priority (number) column 155f of the machine number of the work instruction file 155a. Then, the priority determination unit 127 determines whether there is a machine having a value other than 0 and the highest priority value (the machine with the lowest priority), not including the work item already performed. (S63). If there is such a car (Yes in S63), the priority determination unit 127 ends the process with the car being excluded. On the other hand, if there is no such machine (S63: No), the process proceeds to step S64.

  In step S64, the priority determination unit 127 determines the value of the priority (place) column 155i of the work place in the work instruction file 155a. Then, the priority determination unit 127 determines whether there is a work place having a value other than 0 and having the highest priority value (work place having the lowest priority) without including the work item already performed. (S65). If there is such a work place (Yes in S65), the priority determination unit 127 ends the process with the work place as an exclusion target. On the other hand, when there is no such work place (S65: No), the process proceeds to step S66.

  In step S66, the priority determination unit 127 determines the value of the priority (machine) column 1551 of the target device in the work instruction file 155a. Then, the priority determination unit 127 determines whether there is a target device having a value other than 0 and the highest priority value (the target device with the lowest priority) without including the work item already performed. To judge. If there is such a target device (Yes in S67), the priority determination unit 127 ends the process with such a target device as an exclusion target. On the other hand, if there is no such target device (No in S67), the process proceeds to step S68.

In step S68, the priority determination unit 127 determines the value of the priority (argument) column 155o of the work item in the work instruction file 155a. Then, among the work items that have not been implemented yet, the priority determination unit 127 processes the work item having a value other than 0 and the highest priority value (work item having the lowest priority) as an exclusion target. Finish.
At this time, with respect to the excluded work items, when there are no remaining items after the exclusion, the work items of the excluded work items are added to the remaining items and within the remaining time.

  As described above, by managing work items in units of units, such as a property, a machine, a work place, and a target device, it is possible to determine an exclusion target without decreasing the efficiency of the carryover work as much as possible. In addition, if work items can be excluded by category such as property at the beginning of priority determination, work time can be secured, and thereafter priority determination processing is performed until there are no remaining items or no remaining work time. Instead, the work can be carried out, and the processing load can be reduced.

  In the first embodiment, as shown in FIG. 17, priority comparisons are performed sequentially from the top categories in the work target category, in other words, from the category including a large number of work items. However, the first embodiment is not limited to such an example. For example, the priority determination unit 127 may exclude work objects in order from work items with lower priorities, instead of excluding the work objects. In such a case, it is not necessary for the priority setting unit 154 of the server device 150 to calculate the priority and work time for each work target and set the work instruction file.

  FIG. 18 is a flowchart showing post-processing in the work instruction system 100 according to the first embodiment.

First, after returning from the work site to the office, the worker activates the work instruction display processing unit 120 to connect to the network in the office (S70).
When the work instruction display processing unit 120 is activated, the upload unit 122 uploads the work result and the like to the server apparatus 150 via the communication unit 114 in accordance with the instruction from the input reception unit 112 (S71).

  As described above, according to the work instruction system 100 according to the first embodiment, in the case where all remaining items can not be implemented within the remaining work time according to the progress of the work, the priority of the remaining items is considered. Work instructions can be displayed. In this way, even if all work items can not be completed in time due to work delays due to lack of skills, sudden work occurrences, customer requests, etc., workers can be made to carry out work items with high priority. it can.
