Description

  The present invention relates to a work management system for managing work such as maintenance, inspection, and repair related to equipment.

  When performing maintenance work such as equipment maintenance, inspection, and refurbishment, it may be required to work on a plurality of related equipment without omission.

  For example, a railroad crossing, which is one of railway signal facilities, is configured as a set of a plurality of facilities such as a power supply device, an alarm device, and a breaker. For this reason, when inspecting a level crossing, it is required to inspect all of these related facilities without omission. Normally, each equipment that constitutes a railroad crossing is connected to the equipment box by an electric cable, so the maintenance work is proceeded by checking the related equipment by following the electrical cable coming out of the equipment box at the railroad crossing. It was.

  In addition, each equipment subject to work has an inspection table that describes the work procedure, and the operator carries the inspection table of the corresponding equipment to the work site and refers to this to perform work on each equipment. The work was managed in such a way that the result of the work was entered in the inspection table at the site, and this was taken back to the office for storage.

  Conventionally, since the related equipment was confirmed by the method of following the electrical cable coming out of the instrument box as described above, there was a risk of leakage in grasping the related equipment. Workers also had to carry a number of inspection charts for use at each site during the day's work.

  For such problems, for example, in the lifeline field where facilities to be worked are scattered over a wide range such as water, gas, electricity, etc., the position information is wirelessly transmitted from the portable terminal held by the worker to the server computer. When the mobile terminal approaches the field device in question, the simultaneous maintenance information, which is information about other field devices that should be maintained at the same time as the field device, is wirelessly transmitted from the server computer to be displayed. A maintenance support system is proposed (for example, see Patent Document 1). In the maintenance support system, when an operator leaves the site in the middle of work on a plurality of field devices to be maintained at the same time, this is detected and a warning is issued, thereby preventing work leakage.

There is also a problem that communication costs for wireless communication increase.

  Furthermore, in the above system, a warning is issued when the user leaves the work site during work. However, there may be a case where the day is closed during work. It is desirable to be able to correctly recognize to which equipment the work has been completed and from which equipment the work should be continued when the work is resumed at a later date.

  The present invention has been made in view of the above-mentioned problems, and without connecting to a server from the field, a plurality of related equipment can be specified by a portable terminal and work can be proceeded without omission. The purpose is to provide a work management system that can manage the progress information while leaving it on site.

In addition, the work procedure file 16a includes reference values for determining pass / fail of inspection results, past inspection data, fixed phrases indicating the contents of voice guidance to be output at the start and end of work, and other fixed display information. Etc. are also registered. The items and contents registered in the work procedure file 16a may be appropriately changed according to work contents and inspection contents.

  FIG. 6A shows information registered in the device IC tag 41. In the device IC tag 41, a unique IC tag number assigned to the device IC tag 41, work progress information, a worker ID, a work end date and time, and a work result are registered.

  FIG. 7 shows a schematic configuration of the mobile terminal 20. The portable terminal 20 includes an IC tag input / output processing unit 23, a storage unit 24, a speech recognition unit 25, a speech synthesis unit 26, an operation display unit 28, a control unit 22 mainly composed of a CPU, ROM, RAM, and the like. An input / output unit 29, a clock unit 31, and the like are connected.

  The IC tag input / output processing unit 23 is a reader / writer for reading and writing information with respect to the device IC tag 41 and the name IC tag 42. The storage means 24 stores a work procedure file 16a downloaded from the management apparatus 10. The voice synthesis unit 26 synthesizes and amplifies voice signals for voice guidance for each work process based on the work procedure file 16 a stored in the storage unit 24, and outputs the voice signal to the speaker 21 a of the headset 21. A phoneme / dictionary file 26a serving as basic data for synthesizing a voice signal is connected to the voice synthesizer 26.

  The voice recognition unit 25 has a function of capturing and analyzing a voice signal input from the microphone 21b of the headset 21 and recognizing the contents as words.

  The operation display unit 28 includes a small liquid crystal display, a touch panel provided on the screen, and various switches. The input / output unit 29 functions to exchange data with an external device. For example, data is exchanged with the management apparatus 10 through the terminal I / F unit 13. The clock unit 31 measures the date and date (hour, minute, second). For example, the time measured by the clock unit 31 at the end of the work is set as the work end time.

  The control means 22 controls the operation of the entire mobile terminal 20 based on a program such as the work support program 33 stored in the ROM. When the IC tag input / output processing unit 23 reads information from the device IC tag 41, the work support program 33 is activated.

  The work support program 33 is configured with programs for realizing functions such as a work procedure extraction unit 33a, a work procedure processing unit 33b, a history storage processing unit 33c, a voice input / output unit 33d, and an end / interruption processing unit 33e.

  The work procedure extraction unit 33a uses the IC tag number (specific information) read from the device IC tag 41 provided in the representative equipment FR of each area E as a key, and the IC tag number same as this IC tag number is the header unit 51. The function of extracting the work procedure file 16a registered in the storage means 24 is fulfilled. Further, the function of determining which work process in the work procedure file 16a should start voice guidance based on the progress information read from the device IC tag 41 is achieved. The IC tag number may be included in the file name of the work procedure file 16a, and the corresponding work procedure file 16a may be extracted from the comparison between the IC tag number and the file name.

  The work procedure processing unit 33b performs a voice guidance for each work process from the start position determined by the work procedure extraction unit 33a using the work procedure file 16a extracted by the work procedure extraction unit 33a. Here, when a work end notification is received from the worker M for the work process in which the voice guidance is output from the voice synthesis unit 26, the voice synthesis unit 26 is controlled to output the voice guidance for the next work process. . More specifically, after outputting voice guidance for a certain work process from the voice synthesizer 26, when a specific phrase such as “OK” is recognized by voice, it is determined that an end notification for the work process has been received and the next We are proceeding to the work process.

  The history storage processing unit 33c performs processing for registering the work history of the work process in the work history registration field 53 of the work procedure file 16a for each work process. In addition, it may be configured to measure the work time required for each work process and to store this as one work history. The work time is, for example, the time from when the voice guidance for a certain work process is output to the time when the word “OK” is recognized (received completion notification) (except during the break) Keep time.

  The voice input / output unit 33d receives the text data output as voice guidance from the work procedure processing unit 33b and outputs it to the voice synthesis unit 26, or delivers the words recognized by the voice recognition unit 25 to the work procedure processing unit 33b. Fulfills the interface function.

  The end / interrupt processing unit 33e displays progress information indicating the progress status of the work at that time, the worker ID of the worker M who was performing the work, and the like when the work is interrupted or finished. To control writing to the device IC tag 41.

  Next, the work flow in the work management system 5 will be described.

  Preparation work is performed in the management apparatus 10 before the start of work on site. It is assumed that the equipment ledger 14a and work plan data 15a are created and stored before this preparation work. In addition, the device IC tag 41 and the name IC tag 42 are assumed to have necessary initial data recorded therein, provided in the corresponding representative facility FR, and passed to the worker M.

  When the management device 10 inputs an instruction to start a maintenance work process with a designated work period by an administrator or the like, the control unit 11 of the management apparatus 10 is a device that should perform the work during the designated work period ( The first crossing etc.) is extracted from the work plan data 15a. In the example shown in FIG. 8, “January” is designated as the work period, and the first and second railroad crossings planned to be executed during that period are extracted from the work plan data 15a (P1).

  Next, the control unit 11 extracts the facility information J corresponding to the work target device (such as the first railroad crossing) extracted from the work plan data 15a from the equipment ledger 14a (P2). Further, a work procedure file 16a corresponding to all devices to be worked extracted from the work plan data 15a is extracted from the work procedure data storage unit 16 (P3). In the example of FIG. 8, a work procedure file 16a (K1) corresponding to the first level crossing and a work procedure file 16a (K2) corresponding to the second level crossing are extracted.

  Thereafter, these work procedure files 16a (K1, K2) and the previously extracted equipment information J are downloaded to the portable terminal 20 via the terminal I / F unit 13 and stored in the storage means 24 (P4).

  Thus, if the management apparatus 10 registers work plan data 15a such as an annual plan in advance, the work procedure file 16a relating to work to be performed during the work period can be automatically extracted just by specifying the work period. Therefore, the work of the manager is reduced and human error is unlikely to occur, and the work procedure file 16a necessary for the work at that time is downloaded to the portable terminal 20 quickly and reliably.

  Next, the work of the worker M will be described.

  FIG. 9 shows a flow of work by the worker M. The worker M goes to the planned site with the portable terminal 20 having the necessary work procedure file 16a downloaded as described above. At this time, first, the portable terminal 20 is held over the own name IC tag 42 to cause the portable terminal 20 to read the worker ID and the like from the name IC tag 42 (step S101).

  When the worker M arrives at the corresponding area E (for example, the place where the first railroad crossing), the apparatus IC tag is held by holding the mobile terminal 20 over the apparatus IC tag 41 provided in the representative facility FR of the area E. Information is read from 41 (step S102). Here, the power supply device is the representative facility FR. The portable terminal 20 specifies the work procedure file 16a corresponding to the area E from the storage unit 24 using the IC tag number (specific information) read from the device IC tag 41 attached to the representative facility FR as a key. Then, based on the progress information read from the device IC tag 41, voice guidance is started from the corresponding work process in the specified work procedure file 16a. The worker M advances the work of each work process according to the voice guidance flowing from the speaker 21a connected to the mobile terminal 20 (step S103).

  For example, when work is performed from the first work process on the first level crossing using the work procedure file 16a shown in FIG. 5, first, work steps a1-01 to a1-N relating to the power supply device of the first level crossing are performed. Voice guidance is sequentially output in accordance with the progress of the operator's work. When the last work process for the power supply device is completed, a voice guidance such as “Please check the alarm next” is output, and the worker M is prompted to move to the alarm.

  After that, the work from the work steps a2-01 to a2-N for the first level crossing alarm device is performed according to the voice guidance, and when the operation for the alarm device is completed, a voice such as "Next, check the circuit breaker." The guidance is output and the operator M is prompted to move to the breaker. Furthermore, work steps a3-01 to a3-N for the first level crossing are performed according to voice guidance, and when the work for the circuit breaker is completed, “This area is over. This is the end information for the device IC tag. Voice guidance such as “Please write” is output. The worker M operates the portable terminal 20 according to this voice guidance to write end information to the device IC tag 41. Thereafter, for example, the worker M is prompted to move to the next area.

  When the work process for all the facilities F in a certain area E is completed, or when the work is interrupted at any work process due to the end of working hours, the worker M performs an operation of ending or suspending the work (end button Or the operation of the interruption button or the utterance of “end”, “interruption”, etc.) to the portable terminal 20, the portable terminal 20 is placed on the device IC tag 41 provided in the representative facility FR of the area E. Hold it over (step S104). As a result, completion information such as the work progress status (work process number), worker ID, and time information (work end date / time) at that time is written in the device IC tag 41, and the device IC tag 41 is registered. The content is updated.

  When the worker M moves to the next area E and continues the work (step S105; Y), the worker M moves to the area E and performs the same work from step S102. When ending today's work in this area E (step S105; N), it returns to the office, uploads the work history recorded in the portable terminal 20 to the management device 10 (step S106), and the work ends ( End). This upload operation may be performed by an administrator. In addition, it may be configured to provide voice guidance to return to the office when the closing time is near or when all the work scheduled for today is completed.

  Here, the management apparatus 10 extracts data related to the work history stored in the work procedure file 16a uploaded from the mobile terminal 20, and stores it in the maintenance information storage unit 15 as a separate history file (work history data 15b). It is like that. The management apparatus 10 statistically processes the work time of each work process, each equipment, or the area E from the accumulated work history data 15b, and calculates the standard work time.

  FIG. 6B shows an example of registered contents of the device IC tag 41 when the previous work is completed. Reading the information of the device IC tag 41 reveals the following. Since the progress information is “completed”, the previous work was completed for all the facilities in the area E. The previous work was performed by the worker with worker ID “A001”. The previous work end date and time is 4:20:30 on June 20, 2006. The previous work has been completed successfully. For example, when the device IC tag 41 is read by the mobile terminal 20, the above information may be displayed on the screen of the mobile terminal 20.

  FIG. 6C shows an example of registration contents of the device IC tag 41 in which the end-of-work information is written due to the interruption of work. In this example, the work up to the work process of work process number “a2-02” is completed, the worker ID of the worker M is “M005”, and the work end date and time when the work is interrupted is 2007. The fact that it is 5:00 am on February 12, etc. is recorded in the device IC tag 41.

  The next day, when the worker M comes to this area E and starts the work shown in FIG. 9, the information shown in FIG. 6C is read from the device IC tag 41 in the work of step S102. Based on this information, the portable terminal 20 starts the audio guidance of the work from the work process next to the work process number “a2-02”.

  FIG. 6D shows an example of registered contents of the device IC tag 41 when all work processes are completed and the end information is written. “Complete” is registered in the progress information column. In this example, it is registered that the worker ID is “M005” and that the work end date and time is 1:33:00 on February 13, 2007.

  For example, a warning period (for example, two months) for duplicate work for the same area E is set in advance, information read from the device IC tag 41 indicates completion of work, and the current date and time is within the warning period from the work end date and time. In such a case, it may be configured to automatically issue a warning to prevent the occurrence of duplicate work.

  FIG. 10 shows a flow of processing performed by the mobile terminal 20. When the worker M holds the portable terminal 20 over the name IC tag 42, the portable terminal 20 reads the worker ID from the name IC tag 42 and stores it in the internal memory (step S201). When the worker arrives at the site area E and holds the portable terminal 20 over the device IC tag 41 provided in the representative facility FR, the IC tag number (specific information) or Information such as progress information is read and stored in the internal memory (step S202). Next, the work procedure file 16a corresponding to the read IC tag number is searched in the storage means 24 of the own terminal 20 (step S203). If the corresponding work procedure file 16a is not stored in the storage means 24 (step S204; N), an error notification to that effect (output of warning sound or display of error message) is performed (step S205) and the process is terminated. (End)

  When the work procedure file 16a matching the IC tag number read from the device IC tag 41 is stored in the storage means 24 (step S204; Y), the progress information (work process number) read from the device IC tag 41 is included. The corresponding work process is set as the voice guidance start position (step S206).

  Next, voice guidance data (work contents) corresponding to the work process is read from the corresponding work procedure file 16a, and a voice signal corresponding to the guidance voice data is synthesized by the voice synthesizer 26, and the speaker 21a of the headset 21 is synthesized. Is output as voice guidance (step S207).

  After outputting the voice guidance, the mobile terminal 20 enters a voice recognition process execution state for the voice of the worker M input from the microphone 21b (step S208). Here, when a specific phrase such as “OK” is recognized (step S209; Y), the work result is registered in the work history registration field 53 corresponding to the current work process (“normal” in case of OK), and the work is completed. A work history such as time and worker ID is stored (step S210).

  After storing the work history, the process proceeds to the next work process (step S211). Here, when the next work process is registered in the work procedure file 16a (step S212; N), the process returns to step S207 to execute the voice guidance output process for the next work process. If the next work process is not registered in the work procedure file 16a, the work related to the work procedure file 16a (this area E, for example, the first level crossing) is completed (step S212; Y), and the device IC tag 41 is read. Then, end information for work completion as shown in FIG. 6D is written (step S214), and the process is ended (END).

  If a work interruption operation is received in the middle of the work (step S213; Y), the work interruption end information as shown in FIG. 6C is written to the device IC tag 41 (step S214). ), The process ends (END).

  Although omitted in the flowchart shown in FIG. 10, the speech recognition also recognizes words other than “OK”, such as “Start”, “End”, “Stop”, “Ended”, etc. Then, processing according to the recognition result is performed. Furthermore, although omitted in FIG. 10, various operation buttons are also accepted, and processing corresponding to those operations is also performed.

  As described above, in the work management system 5 according to the present embodiment, the device IC tag 41 is provided only in one of the plurality of facilities F (representative facility FR) arranged in the area E, and this device IC tag. In 41, specific information (IC tag number) for specifying a plurality of facilities F in the area E and work progress information in the area E are stored. For this reason, based on the specific information read from the device IC tag 41, all the facilities F existing in the area E can be specified, and work leakage such as work missing for any of the facilities F can be prevented. it can.

  Even when there are a plurality of areas E, the work procedure file 16a for the area E is correctly identified based on the identification information read from the device IC tag 41 provided in the representative equipment FR of the area E. No erroneous work is performed based on the work procedure file 16a for the area E.

  Further, even if the work is interrupted halfway, the progress information at the time of interruption is written in the device IC tag 41. Therefore, when the work is resumed later, which work process of which equipment is determined by the progress information read from the device IC tag 41. It is possible to recognize whether the work has been completed, and the work can be resumed from the work process according to the progress, that is, the work process following the previous interruption.

  Furthermore, since work progress information is recorded and managed only in one device IC tag 41 in the area E, progress information for a plurality of facilities F in the area E is centrally managed in the area E as a unit. Further, since the progress information of the work is recorded in the device IC tag 41 provided at the site, the worker M does not connect the portable terminal 20 to the office server or the like by wireless communication at each site (region E). It is possible to know the progress information of the work in E. Furthermore, even if there is a mess such as the mobile terminal 20 being mistaken for another worker, the work guidance is started based on the progress information recorded in the device IC tag 41. Work can be resumed correctly from the equipment and work process.

  Even when the portable terminal 20 does not have the function of specifying the work procedure file 16a and guiding the work, for example, the specific information and progress information read from the device IC tag 41 are displayed on the display screen of the portable terminal 20. If the information is displayed on the screen or the content is notified to the worker M by voice, the worker M confirms the work target equipment F in the area E and the progress of work on the equipment F. Can be used for work.

  In addition, since the work contents of each work process are voice-guided, the worker M can proceed with the work without memorizing the work procedure manual. Further, each work process is voice-guided according to the work procedure file 16a, and a response such as “OK” is confirmed and the process proceeds to the next work process. Therefore, the work is performed according to the work procedure registered in the work procedure file 16a. Is strictly observed. Further, since the fact that the word “OK” has been recognized is recorded as the work history, it can be recorded in the history that the work has been performed reliably as in the work procedure file 16a.

  Moreover, since the words and phrases spoken by the worker M are recognized by voice and instructions and responses from the worker M are accepted, the operation load of the worker M on the portable terminal 20 is reduced.

  Furthermore, since the work history during work is stored in the mobile terminal 20, the work history can be uploaded to the management device 10 from the mobile terminal 20 brought back to the office by the worker M, and the work result is wirelessly transmitted from the site to the management device 10. There is no need to send. In addition, the uploaded work history is accumulated in the management apparatus 10 to enable comprehensive management. For example, the work plan data 15a can be automatically corrected or reviewed by the administrator according to the progress of the work.
