Description

  The present invention relates to a work support device, a work support system, a work support method, and a program.

  The work management for confirming the work to be performed according to the determined procedure at each stage is either management based on information entered by the user or management in its own memory. However, in such work management, there is a problem that when a person forgets a work record, a work omission cannot be warned in a timely manner. Therefore, a work support system has been proposed as an alternative work management.

  For example, Patent Document 1 proposes a work data management method that allows maintenance work and the like to be easily performed even by non-experts. Further, in Patent Document 2, a sign of a failure of a construction machine is detected before an actual failure occurs, and a maintenance worker efficiently visits the user to perform sufficient maintenance response. A maintenance system has been proposed.

  Patent Document 3 proposes a maintenance support system that can reduce the burden on the operator and save labor in maintenance and inspection work for on-site equipment such as power plants and substations. Has been. In the maintenance support system of Patent Document 3, a server including a plurality of databases holding information related to maintenance / inspection work is provided. On the other hand, for the portable terminal carried by the worker, the progress situation is photographed for each predetermined process of the maintenance work by the camera attached to the helmet worn by the worker and transmitted to the server. The server extracts data necessary for the work from the database according to the progress photographed by the camera, and provides information necessary for the work from the display attached to the helmet worn by the worker.

  Thereafter, the worker confirms the work procedure displayed on the display and performs maintenance / inspection work. When there is an excess or deficiency of jigs, tools, parts, or materials required for maintenance / inspection work, the server alerts the worker by giving a warning sound such as a buzzer to the worker via the network and mobile terminal. . Then, when the jigs, tools, parts, and materials required for maintenance / inspection work are appropriate, the server reads the work procedure for the maintenance / inspection target device from the work procedure database and displays the next work content on the display. indicate.

  Furthermore, Patent Document 4 proposes an error work warning system that can select whether or not to issue an alarm according to the contents of the error work even if there is an error work. In the erroneous work warning system of Patent Document 4, the server determines whether the content and procedure of the work that the worker is performing at that time is correct based on various types of monitor information, and the worker tries to make a wrong work. If it is determined that the alarm is present, it is determined whether an alarm may be issued to the worker based on the monitor information at that time. For example, if there is a possibility of causing another mistake by giving an alarm, the alarm is not issued. When it is determined that a warning can be given to the worker, the server drives a vibrator, a speaker, and further a red rotating light to give a warning to the worker. However, no warning is issued when it is determined that the worker cannot be alerted.

  However, in the maintenance support system described in Patent Document 3, the mobile terminal always transmits information to the server via the network. Thereafter, the server analyzes the transmitted information and alerts the worker via the network and the mobile terminal. Further, in the erroneous operation warning system described in Patent Document 4 described above, the nurse can only use the environment where the wearable sensor unit can be connected to the server via the network. In addition, warning information issued by light or sound information directed to a worker who has performed an erroneous operation cannot alert a worker or the like in an environment where the light or sound information is blocked.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

  In this embodiment, a series of work includes a plurality of work, and any work included in the plurality of work has a relationship between a standard work order and any other work included in the plurality of work. This is what is prescribed. The work order relationship is the order of start or end between two works. The relationship between the work orders is that when the second work is started after the start of the first work, when the second work is started after the end of the first work, the first work is started. It includes any of the case where the second work is finished later and the case where the second work is finished after the end of the first work. The relationship between work orders may be inevitably defined depending on the contents of work, and may be arbitrarily defined regardless of the contents of work.

  A plurality of work orders may be defined between the two works. For example, there may be a work order relationship in which the second work is started after the start of the first work, and the first work is finished after the end of the second work. One work may have a relationship between a plurality of other works and a work order. In addition, regarding the start or end of one work, the relationship between the start or end of other works and the work order may be defined. In this case, the work sequence with the start or end of other work may be logical product (AND condition), logical sum (OR condition) or exclusive logical sum (Exclusive OR condition), or There may be a combination of these.

  A work is said to be independent of a series of work if the relation of the work order is not defined with any work included in the series of work. If there are two series of work and any work included in the series of work is independent of the other series of work, the two series of work are said to be independent of each other. In the present embodiment, one series of work is taken up and described. However, the work support system and the work support apparatus of the present embodiment have two or more independent series of works separately or concurrently. Needless to say, work support processing can be performed.

(Embodiment 1)
FIG. 1 shows a configuration example of a work support system according to an embodiment of the present invention. This work support system supports a worker so that each work is performed in a standard work order when a series of work is performed by a plurality of workers. The network of the work support system includes a work support device 1, a home server terminal 4, and a center server terminal 5. The home server terminal 4 and the center server terminal 5 are connected to the Internet VPN. The work support device 1 and the home server terminal 4 are connected by wireless communication. The home server terminal 4 stores work standard data of a series of work performed by a plurality of workers in cooperation. The center server terminal 5 stores work standard data for various work.

  In the first embodiment, the work support apparatus 1 includes a user wearing terminal 3 and a mobile server terminal 2. The user wearing terminal 3 is worn by each worker who performs the work. For example, it is a terminal in which a microphone or the like is attached in the form of headphones, or a sensor is built in and can be worn on the arm. Each worker carries the mobile server terminal 2 together with the user wearing terminal 3. For example, it is attached to the operator's waist or installed near the operator's work site. The user wearing terminal 3 and the mobile server terminal 2 are connected by wireless communication. The mobile server terminals 2 are connected by an ad hoc wireless LAN 6.

  Before starting work, work standard data necessary for work performed by all workers from the center server terminal 5 is stored in the home server terminal 4 in advance. The home server terminal 4 is connected to the mobile server terminal 2 of each worker via wireless communication, encrypts work standard data of work to be performed by each worker, and transmits the work standard data. The work standard data includes information such as work contents and work order. Work standard data of work to be performed is stored in the mobile server terminal 2 of each worker.

  FIG. 2 is a block diagram showing a configuration example of the work support apparatus according to Embodiment 1 of the present invention. In the first embodiment, as described above, the work support device 1 includes the user wearing terminal 3 and the mobile server terminal 2. The user wearing terminal 3 includes a start / end information acquisition unit 31 and a warning information display unit 32. The mobile server terminal 2 includes a work standard database 21 (hereinafter referred to as work standard DB 21), a start / end information storage unit 22, a determination unit 23, and a transmission / reception unit 24. The work standard data transmitted from the home server terminal 4 described above is stored in the work standard DB 21.

  FIG. 3 is a diagram showing an example of work standard data according to Embodiment 1 of the present invention. For example, work standard data as shown in FIG. 3 is stored in the work standard DB 21 of the mobile server terminal 2 of each worker. In FIG. 3, it is shown that the worker in the column performs the work in the row in the column where the circle is marked. For example, a series of work performed by all workers is work names A, B, C, D, E, F.F. . . It is assumed that this work is included. Each operation A, B, C, D, E, F. . . On the other hand, workers α, β, and γ are assigned. For each work, for example, a work order condition is set such that work B can be performed only after work A starts. There is no need to assign information to each worker.

  The conditions in FIG. 3 define the conditions of the work order for starting each work. As described above, the conditions of the work order for completing each work may be defined. The (start) condition of the work F in FIG. 3 is “none”, but it is assumed that the start or end of the work F is defined as a start or end condition in the subsequent work X that is not described in FIG. .

  Hereinafter, assuming the case where a series of work is performed by a plurality of persons, the operation of the work support apparatus 1 during actual work will be described. First, the operation of the work support device 1 at the start of work will be described.

  When the worker starts work, first, the start / end information acquisition unit 31 of the user-mounted terminal 3 acquires the content of the work to be started and start information indicating that the work is started. The start / end information acquisition unit 31 acquires information indicating that work is started by a camera, a microphone, a sensor, or the like attached to the user wearing terminal 3 of the worker. For example, the start information may be acquired by inputting the start or end of a specific work by the operator operating the switch while viewing the display of the user wearing terminal 3. Alternatively, the user's voice is input with the microphone of the user wearing terminal 3 and the user's voice such as “work XX start” or “work XX end” is recognized to obtain information on the start or end of a specific work. You may make it do. Furthermore, the user mounting terminal 3 may be provided with a camera, and a work target or a tool may be detected from an image captured by the camera to determine the start or end of the work.

  The acquired start information is sent from the start / end information acquisition unit 31 to the determination unit 23 of the mobile server terminal 2. The determination unit 23 determines what kind of information is sent or whether start information or end information conforms to a work standard, which will be described in detail later. When the determination unit 23 determines that the information to be sent is start information, the start information is sent to and stored in the start / end information storage unit 22. The start / end information storage unit 22 stores information on the work that the worker and other workers have started / finished so far. FIG. 4 shows an example of data in the start / end information storage unit according to the first embodiment. For example, data relating to the start / end of work as shown in FIG. 4 is stored in the start / end information storage unit 22 of the mobile server terminal 2 of each worker. In the example shown in FIG. 4, start information and end information are stored for the work A of the worker α, and only start information is stored for the work C of the worker α. However, no information is stored yet for the work D of the worker β.

  The determination unit 23 compares the start information and / or end information stored in the start / end information storage unit 22 with the work standard data, and the start or end of a certain work included in a series of work is set as the work standard. Judge whether it fits. In determining, the determination unit 23 reads work information necessary for determination from the data stored in the start / end information storage unit 22 and the work standard DB 21. As described above, the work standard DB 21 contains work standard data indicating the contents of a series of work and the standard work order, and the start / end information storage unit 22 has started and ended by workers and other workers so far. Stores information about completed work. Based on these pieces of work information, it is determined whether or not the work standards are met.

  In the example shown in FIG. 3 and FIG. 4, when the start information of the work C of the worker α is sent, the work standard DB 21 has the condition of (after the end of A) ∩ (after the end of B). Read data. Further, from the start / end information storage unit 22, the end information of the work A of the worker α, the end information of the work A of the worker γ, and the end information of the work B of the worker β are read. Based on these data, the determination unit 23 determines whether the work started by the worker conforms to the work standard. That is, it is determined whether or not the work to be started conforms to the standard work order. In this example, since the work A and the work B are completed before the work C is started, it is determined that the start of the work C conforms to the work standard.

  If the determination unit 23 determines that the work standard is met, the determination unit 23 sends the received start information to the transmission / reception unit 24. The mobile server terminals 2 of the work support apparatus 1 are connected by an ad hoc wireless LAN 6, and can be wirelessly communicated with other mobile server terminals 2 by the transmission / reception unit 24. The transmission / reception unit 24 encrypts the start information and transmits it to the mobile server terminal 2 of another worker. The mobile server terminal 2 of another worker receives the start information by the transmission / reception unit 24. In other mobile server terminals 2, the received start information is sent to the determination unit 23 and is stored in the start / end information storage unit 22 when it is determined that the start information is start information.

  If the determination unit 23 determines that the start of work does not conform to the work standard, the determination unit 23 wirelessly sends warning information to the warning information display unit 32 of the user wearing terminal 3. In the example shown in FIG. 3, for example, the work of B is started before the work of A is finished, and it is determined that the work has been started in the wrong work order. When the warning information is sent, the warning information display unit 32 displays the warning information to the worker by means such as sound, light, vibration or display on the display. In this case, the determination unit 23 sends warning information to the warning information display unit 32 and also sends warning information to the transmission / reception unit 24. The transmission / reception unit 24 encrypts the warning information and transmits it to the mobile server terminal 2 of another worker wirelessly.

  The mobile server terminal 2 of another worker receives the warning information by the transmission / reception unit 24. The received warning information is sent to the determination unit 23. When determining that the information is warning information, the determination unit 23 wirelessly transmits the warning information to the warning information display unit 32 of the user wearing terminal 3. When the warning information is sent to the warning information display unit 32, the warning information is also displayed to other workers holding the user wearing terminal 3 by means such as sound, light, vibration or display on the display.

  Hereinafter, the operation of the work support apparatus 1 at the end of the work will be described.

    When the worker finishes the work, first, the start / end information acquisition unit 31 of the user wearing terminal 3 acquires the end information. Details such as the end information acquisition means are the same as the start information. The start / end information acquisition unit 31 sends the acquired end information to the mobile server terminal 2. The end information sent to the mobile server terminal 2 is sent to the determination unit 23. When determining that the sent information is end information, the determination unit 23 stores the end information in the start / end information storage unit 22. Further, the determination unit 23 sends the end information to the transmission / reception unit 24. The transmission / reception unit 24 encrypts the end information and transmits it to the mobile server terminal 2 of another worker. In addition, the determination unit 23 determines whether or not all the operations in the series of operations have been completed based on the completion information. When all the work of a series of work is completed by a certain end information, the work support process is ended.

  When the transmission / reception unit 24 of the mobile server terminal 2 of another worker receives the end information, the transmission / reception unit 24 sends the received end information to the determination unit 23. If the determination unit 23 determines that the received information is end information, the determination unit 23 stores the end information in the start / end information storage unit 22.

  The determination unit 23 determines whether the end information conforms to the work standard in the same manner as the start information. If it is determined that it conforms to the work standard, the received end information is sent to the transmission / reception unit 24. The transmission / reception unit 24 encrypts the end information and transmits it to the mobile server terminal 2 of another worker. The mobile server terminal 2 of another worker receives the end information by the transmission / reception unit 24. In another mobile server terminal 2, the received end information is sent to the determination unit 23 and is stored in the start / end information storage unit 22 when it is determined that the end information is the end information.

  If the determination unit 23 determines that the start of work does not conform to the work standard, the determination unit 23 wirelessly sends warning information to the warning information display unit 32 of the user wearing terminal 3. In such a situation, the start information (or end information) of the first work is defined when the procedure stipulates that the second work is ended after the start (or end) of the first work. Occurs when the end information of the second work is acquired before acquiring. When the warning information is sent, the warning information display unit 32 displays the warning information to the worker by means such as sound, light, vibration or display on the display.

  The determination unit 23 also sends warning information to the transmission / reception unit 24. The transmission / reception unit 24 encrypts the warning information and transmits it to the mobile server terminal 2 of another worker wirelessly. In the mobile server terminal 2 of another worker, the received warning information is sent to the warning information display unit 32 of the user wearing terminal 3 and displayed in the same manner as when it is determined that the start information is not suitable.

  The determination unit 23 determines whether or not all work in a series of work has been completed based on the end information. If all work has been completed, the work support process is terminated. As shown in the example of FIG. 3, if the work standard data does not have a work order condition for the work end, it is determined that all the end information conforms to the work standard and is stored in the start / end information storage unit 22. .

  The work support apparatus 1 according to the embodiment stores work standard data, start information, and end information, determines whether or not the work standard is satisfied, and transmits warning information (work support apparatus in a narrow sense). And an alarm display device that receives and displays the warning information. From this viewpoint, the work determination device (work support device in a narrow sense) includes a start / end information acquisition unit 31, a work standard DB 21, a start / end information storage unit 22, a determination unit 23, and a transmission / reception unit 24. The alarm display device includes a transmission / reception unit 24, a determination unit 23, and a warning information display unit 32. If the warning information display unit 32 is added to the work determination device, warning information related to the worker's unsuitable work can be displayed to the worker. The work support device 1 of the present embodiment has a symmetrical configuration including a work determination device and a warning display device.

  FIG. 5 is a flowchart showing an example of the work recording / judgment operation of the work support system according to Embodiment 1 of the present invention. The worker's own work record and the judgment operation associated therewith will be described. When this work support system is started, the system is first waiting for an event (step S101). Next, the determination unit 23 determines whether there is an event input (step S102). If there is no event input (step S102; NO), the process returns to waiting for an event (step S102).

  If there is an event input (step S102; YES), the determination unit 23 stores the start information or end information of the event in the start / end information storage unit 22 (step S103). Further, the start information and / or end information is read from the start / end information storage unit 22, and the work standard data stored in the work standard DB 21 is read (step S104).

  Next, the determination unit 23 determines whether the start information or the end information conforms to the work standard (step S105). When it is determined that it conforms to the work standard (step S105; YES), the start information or the end information is sent to the transmission / reception unit 24 and transmitted to the work support device 1 of another worker by wireless communication (step S106). ). Further, the determination unit 23 determines whether or not all work has been completed based on the end information (step S107). If all work has not been completed (step S107; NO), the process returns to the event waiting state in step S101. If all the work is finished (step S107; YES), the work recording / determination process is finished.

  When the determination unit 23 determines that the start information or the end information is not suitable for the work standard (step S105; NO), the determination unit 23 sends the warning information to the warning information display unit 32, and the warning information is a means such as sound or light. Is displayed (step S108). The determination unit 23 also sends the warning information to the transmission / reception unit 24, and transmits the warning information to the work support device 1 of another worker by wireless communication (step S109).

  FIG. 6 is a flowchart showing an example of a work recording / judgment operation of another worker of the work support system according to the first embodiment. A description will be given of a work record and a judgment operation associated therewith when receiving some information from another worker. When this work support process is started, it is in a state of waiting for received data (step S201). Next, the determination unit 23 determines whether there is received data (step S202). If there is no received data (step S202; NO), the process returns to waiting for an event (step S201).

  If there is received data (step S202; YES), the determination unit 23 determines whether the received data is start information, end information, or warning information (step S203). If it is start information (step S203; start), the received start information is stored in the start / end information storage unit 22 (step S204). If it is determined that it is end information (step S203; end), the end information is sent to and stored in the start / end information storage unit 22 (step S205). Further, the determination unit 23 determines whether or not all work has been completed based on the end information (step S207). If all work has not been completed (step S207; NO), the process returns to step S201 and waits for received data. Repeat from. If all work is finished (step S207; YES), this work support process is finished.

  If it is determined in step S203 that the received data is warning information (step S203; warning), the warning information is sent to the warning information display unit 32, and the warning information is displayed by means such as an alarm or light (step S206). ). And it returns to step S201 and repeats the above process from reception data waiting.

  As described above, according to the first embodiment, it is possible to notify other workers that a certain worker performs a non-conforming operation in a plurality of tasks. That is, since the work support devices 1 are connected to each other by wireless means, the start / end information of all workers can be shared. Therefore, if the start / end information is different from the work standard, Warning information can be issued to the person himself / herself, and warning information can also be issued to other workers. As a result, it can be expected to work properly in the joint work with a plurality of people without any work omission and to prevent troubles resulting from the work omission. This is particularly effective in construction sites where it is difficult to communicate directly due to noise, or in elevator repairs where remote joint work is required.

  In the first embodiment, since the mobile server terminals 2 of a plurality of workers are connected by the ad hoc wireless LAN 6, each worker can directly connect without going through a wireless hub, a wireless router, a base station, or the like. Wireless communication is possible. Therefore, even if an infrastructure such as a wireless hub, a wireless router, or a base station is not installed, it is possible to notify other workers that a certain worker performs a non-conforming work in the work of a plurality of persons.

(Embodiment 2)
The second embodiment of the present invention is different from the first embodiment in that the work time is also determined. The network of the work support system according to the second embodiment is the same as that of the first embodiment, and has a configuration as shown in FIG. 1, for example. Similarly, the work support apparatus 1 includes a mobile server terminal 2 and a user wearing terminal 3. The operation of storing work standard data via the network before starting work is the same as that in the first embodiment.

  FIG. 7 is a block diagram showing a configuration example of the work support apparatus according to Embodiment 2 of the present invention. The second embodiment is different from the first embodiment in two points. First, the work standard DB 21 and the start / end information storage unit 22 include information related to work time. FIG. 8 is a diagram illustrating an example of work standard data according to the second embodiment. For example, work standard data as shown in FIG. 8 is stored in the work standard DB 21 of each worker's mobile server terminal 2. In the second embodiment, work standard data about work time is also included. In the example shown in FIG. 8, for example, a condition of a start time limit is defined such that the work B must start within 20 minutes from the start of the work A.

  Although the example of FIG. 8 describes only the time limit for starting each work, the time limit for ending a certain work may be defined as the time limit. For example, there may be a time limit condition in which the operation D must be completed within x minutes after the operation B is started. In addition, the starting point of the time limit is not limited to the start of work, and the time limit from the end of a work may be defined. The work at the start point and the work at the end point of the time limit are not necessarily adjacent to each other in the work standard data.

  Formally, the time limit is the time until the second work starts after the start of the first work, the time until the second work starts after the end of the first work, The time until the second work is finished after the start of the first work, the time until the second work is finished after the end of the first work, or from the start of a certain work Includes any time until the end of the work. The time limit condition may define the elapsed time from the start or end of other tasks. In this case, the time limit condition from the start or end of other tasks may be logical product (AND condition), logical sum (OR condition) or exclusive logical sum (Exclusive OR condition). Or a combination thereof. Note that the start point or end point of the time limit and the start or end conditions of the work may be defined independently.

  FIG. 9 shows an example of data in the start / end information storage unit according to the second embodiment. The start / end information storage unit 22 stores not only the information about the start / end described in the first embodiment, but also information about when a specific work is started, that is, when the start information is acquired. In FIG. 9, hx: my (hour: minute) following “start” represents the time when the start information is acquired. For example, in the example shown in FIG. 9, not only the start / end information about the work B of the worker β but also the information that the start information about the work B of the worker β is acquired at h3: m3 is stored. .

  The second difference is that the mobile server terminal 2 includes a work time measuring unit 25. The work time measuring unit 25 measures the elapsed time from the start or end of the work that is the starting point of the time limit of the work standard data. Basically, the time from when the start information or the end information of the work that is the starting point of the time limit is acquired until the time limit elapses is measured. The work time measuring unit 25 does not always measure the time limit. For example, in order to give a notice of the time limit, a time shorter than the time limit (notice time) may be measured. In addition, there may be a case where a time longer than the time limit (grace time) is measured in order to grace the warning.

  Hereinafter, assuming the case where a series of work is performed by a plurality of persons, the operation of the work support apparatus 1 during actual work will be described. When receiving the start information or the end information, the determination unit 23 checks whether the start information or the end information is the start point of the time limit of the work standard data. When the start information or the end information is the start point of the time limit for work, the determination unit 23 sets a predetermined time calculated from the time limit in the work time measurement unit 25 and starts measurement. The predetermined time calculated from the time limit (hereinafter referred to as “working time”) is the time limit itself or the aforementioned notice time or grace time.

  Alternatively, when the start information or the end information is the start point of the time limit for the work, the determination unit 23 adds the time when the start information or the end information is acquired to the start information or the end information of the work. And stored in the start / end information storage unit 22. In that case, the work time measuring unit 25 outputs the current time data. Whether the work time has elapsed can be determined from the time of the stored start information or end information and the current time.

  A process for determining whether the work time conforms to the work standard will be described by taking the work start time as an example. The embodiment is that when the worker starts work, the start / end information acquisition unit 31 of the user-mounted terminal 3 acquires the start information and sends the start information from the start / end information acquisition unit 31 to the mobile server terminal 2. Same as 1. In the second embodiment, the determination unit 23 determines whether the work time has elapsed before the start information of a specific work is acquired. For example, in the example shown in FIG. 8, whether 20 minutes have elapsed since the start information of work A was acquired (when the work time is the same as the time limit) before the start information of work B is acquired. Judge whether or not.

  In making the determination, work time information necessary for the determination is read from the data stored in the start / end information storage unit 22 and the work standard DB 21. For example, in the example shown in FIGS. 8 and 9, when work C is started, data on the condition of 40 minutes from the start of B is started from the work standard DB 21, and B is started from the start / end information storage unit 22. Read data at time (h3: m3). By comparing these with time information (current time) measured by the work time measuring unit 25, it is determined whether or not a predetermined work time has elapsed.

  When determining that the predetermined working time has elapsed, the determining unit 23 wirelessly transmits warning information to the warning information display unit 32 of the user wearing terminal 3. In the example shown in FIG. 8, 20 minutes have passed since the start of the work A before the start information of the work B is input. Upon receiving the warning information, the warning information display unit 32 displays a warning to the worker by means such as sound, light, vibration, or display on the display. The determination unit 23 sends warning information to the warning information display unit 32 and also sends warning information to the transmission / reception unit 24. The transmission / reception unit 24 encrypts the warning information and transmits it to the mobile server terminal 2 of another worker wirelessly.

  The reception operation of the other work support apparatus 1 is the same as the warning information due to the mistake in the work order described in the first embodiment, and the mobile server terminal 2 of the other worker receives the warning information by the transmission / reception unit 24. . The received warning information is sent to the determination unit 23. When the determination unit 23 determines that the warning information is warning information, the warning information is wirelessly transmitted to the warning information display unit 32 of the user wearing terminal 3. When the warning information is sent to the warning information display unit 32, another worker is also warned by means such as sound, light, vibration or display on the display.

  The operation of the work support apparatus 1 after the predetermined work time has not elapsed and the start information or the end information is acquired is substantially the same as that of the first embodiment. In addition to the operation of the first embodiment, the determination unit 23 checks whether the start information or the end information is the start point of the time limit for work standard data. When the start information or the end information is the start point of the work time limit, the determination unit 23 sets the work time in the work time measurement unit 25 and starts measurement. Alternatively, the determination unit 23 adds the time when the start information or the end information is acquired to the start information or the end information of the work and stores it in the start / end information storage unit 22.

  Even when the time limit for completing the work is specified, it is determined whether the work time conforms to the work standard in the same manner as the start of the work. That is, the determination unit 23 conforms to the work standard when the work time (predetermined time calculated from the time limit) elapses before the work end information for which the time limit for completion is specified is acquired. It is determined that it has not been performed, warning information is displayed, and the warning information is transmitted to another work support apparatus 1.

  FIG. 10 is a flowchart illustrating an example of a work recording / determination operation of the work support apparatus according to the second embodiment. The work recording / judgement operation of other workers in the work support system according to the second embodiment is the same as that of the first embodiment (that is, the same as in FIG. 6). Hereinafter, the work record of the worker himself / herself and the determination operation associated therewith in the second embodiment will be described.

  When the work support process is started, the process is first waiting for an event (step S301). Next, the determination unit 23 determines whether or not a predetermined time (working time) has elapsed (step S302). At this time, work time information necessary for determination is read from the data stored in the start / end information storage unit 22 and the work standard DB 21 (not shown). If it is determined that the predetermined time has passed (step S302; YES), the warning information is sent to the warning information display unit 32, and the warning information is displayed by means such as sound and light (step S303). The warning information is also sent to the transmission / reception unit 24 and transmitted to the work support device 1 of another worker by wireless communication (step S303). After that, the process returns to step S301 to wait for event input.

  If it is determined that the predetermined time (working time) has not elapsed (step S302; NO), the determination unit 23 determines whether there is an event input (step S304), and if there is no event input. (Step S304; NO), it returns to the state of waiting for an event. If there is an event input (step S304; YES), the determination unit 23 stores the start information or end information of the event in the start / end information storage unit 22 (step S305). Further, the start information and / or end information is read from the start / end information storage unit 22, and the work standard data stored in the work standard DB 21 is read (step S306).

  At this time, if at least the acquired start information or end information is the start point of the time limit, the start / end information storage unit 22 stores the time when the start information or end information is acquired. When the start information or the end information is the end point of the time limit, the work time measured by the work time measurement unit 25 is reset. If the start information or the end information is the start point of the time limit, the measurement of the work time is started (step S307).

  Next, it is determined whether the start information or the end information matches the work standard (step S308). The subsequent operation is the same as that of the first embodiment. That is, steps S308 to S311 are the same as steps S105 to S109 in FIG. In FIG. 10, step S108 and step S109 of FIG. 5 are combined into one and represented by step S311.

  As described above, according to the second embodiment, similar to the first embodiment, it is possible to notify other workers that a certain worker performs a non-conforming work in a plurality of work. That is, since the work support devices 1 are connected to each other by wireless means, the start / end information of all workers can be shared. Therefore, if the start / end information is different from the work standard, Warning information can be issued to the person himself / herself, and warning information can also be issued to other workers. As a result, it can be expected to work properly in the joint work with a plurality of people without any work omission and to prevent troubles resulting from the work omission. This is particularly effective in construction sites where it is difficult to communicate directly due to noise, or in elevator repairs where remote joint work is required.

  In the second embodiment, as in the first embodiment, since the mobile server terminals 2 of a plurality of workers are connected by an ad hoc wireless LAN 6, a wireless hub, a wireless router, a base station, or the like is used. Each operator can communicate directly and wirelessly without intervention. Therefore, even if an infrastructure such as a wireless hub, a wireless router, or a base station is not installed, it is possible to notify other workers that a certain worker performs a non-conforming work in the work of a plurality of persons.

  Furthermore, in the second embodiment, warning information may be displayed to the worker himself / herself and other workers when the time limit for the task has elapsed before acquiring the work start information or end information. it can. As a result, it can be expected that work can be efficiently performed in joint work by a plurality of persons. For example, in the work at a construction site, when the next work must be performed within a predetermined time from the start of one work, or the work may not be performed even after the predetermined time has passed, the possibility that an abnormality has occurred in another worker It is effective to detect. It is also effective as a means for the supervisor to monitor whether or not the worker is appropriately performing the work.

  In the embodiment, the example in which the network of the work support system is configured by the work support device 1, the home server terminal 4, and the center server terminal 5 has been described for the convenience of managing the work standard information. However, the home server terminal 4 and the center server terminal 5 are not essential components of the present invention, and the work support system may be configured by only the work support device 1 without including them.

  In the embodiment, an example in which only warning information is displayed has been described, but start / end information may be displayed in addition to the warning information. If the start / end information is displayed, it is possible to perform work while confirming the work status of other workers when working with a plurality of persons.

Further, in the embodiment, the example in which the user wearing terminal 3 and the mobile server terminal 2 are communicated by radio is described, but they may be connected by wire.

  In the embodiment, the example in which the work support devices 1 are connected to each other by the ad hoc wireless LAN 6 has been described. However, the communication between the work support devices 1 is not limited to the ad hoc wireless LAN 6. For example, the work support apparatuses 1 may be configured to communicate with each other wirelessly such as a wireless LAN, a mobile phone, or a PHS. Further, the work support devices 1 may be connected to each other by a wired connection such as a LAN or a telephone line. When the mobile server terminals 2 are connected to each other by wire, if the mobile server terminal 2 and the user wearing terminal 3 communicate with each other wirelessly, the worker is not restricted by the communication line.

  Further, in the embodiment, it has been described on the assumption that each worker wears and carries the work support apparatus 1 according to the present invention, but not only the worker but also the manager / supervisor of the work monitors. The work support apparatus 1 may be provided. In this case, the work support device 1 held by the administrator may be an alarm display device that does not have the start / end information acquisition unit 31 and that only receives and displays the warning information. The work support device 1 according to the embodiment stores work standard data, start information, and end information, determines whether or not the work standard is met, and receives warning information. It can be regarded as a symmetric configuration provided with each alarm display device.

  In the embodiment, the user wearing terminal 3 that acquires start / end information and displays warning information has been described. However, information such as precautions regarding work is stored in the mobile server terminal 2 in advance, and the user wearing terminal 3 May be able to receive.

  In the second embodiment, the example is described in which only the start time is stored and the measurement is reset every time the next work is started. However, not only the start time but also the end time is measured, and a new condition is set for the work time. May be attached.
