Next, the operation of the first embodiment of the on-site support system according to the present invention will be described with reference to FIGS. 1 to 3 and FIGS. Referring to FIG. 6, the inspection work (including inspection after repair) by WPC installation worker 1 is performed according to the following process flow. First, at the start of the inspection work, workers (here, workers A and B) who inspect high-temperature components (mainly turbine blades) of the gas turbine are preparing for the following. The WPC shown in FIGS. 1 to 3 is mounted, and is connected to the work management server 20 via the LAN 23 shown in FIG. 4 via the wireless unit 2-2 of the WPC. Work management server 20
Are the parts database 21 and the work management database 2
2 and it is in a state where such information can be extracted at any time.

At the time of inspection, WPC 2 for worker A (B)
4 (25) sends a request for information necessary for the work (work information such as history data of high-temperature parts related to the work, electronic technical manuals, specifications, drawings, design data, etc.) to the work management server 20 to the radio unit 2-. 2 to output by wireless communication. The work management server 20 receives the request via the LAN. Then, in response to the request, the information is acquired from the parts database 21 and the work management database 22, and the information (history data, work information) necessary for the work is sent to the WPC 24 (25) for the worker A (B). Output. Worker A (B)
WPC 24 (25) uses LAN
23, and is received by the wireless unit 2-2 and stored in the storage unit 2-3.

Further, the operation of acquiring information necessary for the operation from the operation management server 20 before the operation can be performed in real time during the operation. The data (current data) stored by the worker A (B) during the work is
It is stored in the worker A (B) WPC 24 (25).

In the inspection work of the turbine blade, first,
Check whether the turbine blade is new (S10
1). In the case of a new product, the format shown in FIG. 5 is first read (from the HD of the WPC body 2 of the worker A WPC 24 or the work management server 20), and the touch panel 5 serving as the input unit 3
-1 (S102). Then, necessary data is input according to the format, and the status of the turbine blade is confirmed and recorded (S104). Then, the current data is stored in the HD of the WPC body 2 of the worker A WPC 24 (S105).

When the turbine blade is not new and is inspected several times, first, the past history data (format shown in FIG. 5) is read from the HD of the WPC body 2 of the worker A WPC 24 or the work management server 20. ) Read and display on the touch panel 3-1 (S103). Check the past damage status from the displayed content and compare it with the current status. Then, based on the result, the current data is additionally written on the past data to make the current data (S104). If necessary (if the damage situation is different from the past,
In the case where the number of records is so large that the data is difficult to see, or for each inspection, etc.), it is possible to newly create current data in the format of FIG. It is also possible to switch the turbine blades 1-1 and 2 (44 and 45) in the data recording section 43 of FIG. In addition, if there is a risk that the test record alone (Fig. 5) may not be able to clearly convey the situation, HMC8
It is also possible to take a photograph and leave an image record attached as auxiliary data. At that time, it is also possible to record the damage status using a drawing tool or to write characters on the image record. After entry, WPC 24 for worker A
Save the data in the HD of the WPC body 2 (S10)
5). The image data of the photograph is also stored in a form attached to or linked to the current data on the inspection record. Numerical values and character data can be input by voice.

After the saving is completed, the worker A WPC 24
The saved current data is sent to the work management server 20 by the wireless unit 2
-2 by wireless communication. The work management server 20
The current data is added to the history data, and the parts database 2
Save to 1. However, it is also possible to output the current data to the work management server 20 by wireless communication from the wireless unit 2-2 to the work management server 20 in real time during the work, and store the data in the parts database 21.

In the inspection work, WPC 24 for worker A
As described above, it is possible to call the electronic work manual, which is work information, from the work management server 20 as described above, and perform the inspection work based on the voice guidance of the electronic work manual while confirming it with the headphones 9. .

The worker A performs repair work according to the damage situation of each turbine blade. In the repair work, it is possible to call the electronic work manual from the work management server 20 as described above using the worker A WPC 24, and to carry out the work based on the electronic work manual. At that time, voice guidance can be used. Further, in order to refer to similar damage cases in the past, the work management server 20 is caused to search for similar case data in other parts, and a repair method at that time, and
It is also possible to retrieve the status of the part after that. That is, the phenomenon items in the column of the phenomenon 46 in FIG. 5 and the information related to the items (in the case of “2. By inputting (item), the search can be performed by a search engine that searches for similar history data in the component database 22.

In addition, the worker A can communicate with the worker B and the worker A WPC 24 at the time of repair.
It uses a PHS function, a mobile phone function, communication using data communication such as that found in Internet phones, and the like.
Thereby, it is possible to receive the advice of the worker B (skilled worker). The worker A sends the image of the repaired part to the worker B at a remote location on the spot to the worker A WP.
An image can be captured using the HMC 8, which is one of the input units 3 of the C24, and transmitted from the wireless unit 2-2. Therefore,
The worker B is also the HM that is the output unit 4 of the worker B WPC 25.
With D7, the situation can be accurately grasped, and appropriate guidance can be provided. That is, the worker A can search for history data, data of other parts, and receive advice from a skilled person while staying at the work site.

After completion of the repair, the worker A repairs the data relating to the repair as well as the repair record data (FIG. 5
Format), or newly created record data. After the entry, the data is stored on the worker A WPC 24 or on the parts database 21 attached to the work management server 20.

At intervals between the inspection and maintenance work and at the stage when the inspection and maintenance work for one day is completed, the above-mentioned data are stored in the W for the worker A.
When the data is recorded in the HD of the WPC main body 2 of the PC 24, the worker A uploads each data from the WPC 24 for the worker A to the parts database 21 attached to the work management server 20. During inspection and maintenance, each data is transmitted to the work management server 20 in real time, and the parts database 21
This is not necessary if you have saved them.

By the above operation, each data in the inspection / maintenance work can be digitized quickly and in real time or near real time, and can be stored in the parts database 21 of the work management server 20. Therefore, there is no need to perform extra data re-input work, and paperless operation can be achieved, leading to a reduction in time and cost. In addition, since the data can easily include the image data of a photograph, the photograph data can be easily extracted even when a person other than the worker A checks the situation later.

In addition to the image data, the type of damage to each turbine blade, the positions of the starting point and the end point, and the length and depth of the damage are stored as specific numerical values. Therefore, it is easy to retrieve data later.
For example, what kind of treatment was done before for a certain injury,
You can quickly search for what the results are now. Therefore, it can be easily used as effective back data when considering how to deal with a similar situation. This can be done at the work site. That is, it becomes easy to check the history of damage to each turbine blade later. In addition, even when performing a statistical study on damage or repair, the data can be used as it is, data processing can be performed accurately, and an accurate study can be performed.

Room 59, engine room 58 having control equipment 51
Is provided. Then, it is assumed that the worker C50, the worker D61, and the worker E62 are involved in adjustment and inspection.

[0115] The ship 63 is a ship. Ship DCS inside
An inboard LAN 54 (to be described later) having an inboard LAN 53 (to be described later) is provided. The engine room 58 is an engine room in which a marine engine is installed. There are various devices related to engines and their control devices. The control equipment 51 as a measuring device has various measuring devices for controlling the engine. And
Various controls are performed based on the information on the measurement results of these measuring devices. The signals of these measuring instruments are transmitted to the ship DCS 53 via the onboard LAN 54, displayed on the display unit, and based on the information, the ship DCS 53
Performs various information processing and control. The measuring device is adjusted by the adjusting device at the time of inspection. I / O room 59

The ECR 60 is a room in which various devices and control systems for controlling the engine are installed, and the ship DCS 53 is one of the control systems. The ship DCS 53 is a control device that controls the engine of the ship with reference to information from the control equipment 51 and other devices. The measurement results of various measuring devices are displayed on the display unit of the ship DCS 53. These values are adjusted during inspection. In addition, it performs overall control onboard. The worker C50 is the WPC-mounted worker 1 having the worker C WPC 50-1 for inspecting and maintaining the equipment of the ship. The worker D61 and the worker E62 are ordinary workers who perform inspection and maintenance of facility equipment of the ship.

Next, the operation of the second embodiment of the site support system according to the present invention will be described with reference to FIGS. 1 to 3, FIGS. In the present embodiment, the adjustment (calibration) of a pressure gauge, which is one of the measuring devices in the engine room 58 of the ship, will be described as an example. Is possible.

The adjustment of the measuring equipment in the engine room 58 of the ship is usually performed by the following process. First, in FIG. 8, ECR60, I /
The workers E are in the O room 59 and the engine room 58, respectively.
62, an operator D61 and an operator C50 are arranged. next,
In the engine room 58, the worker C50 connects the pressure generator to a pressure gauge, which is a measuring device in the control equipment 51. Then, a constant pressure is generated by the pressure generator to adjust the value of the pressure gauge. At the same time, the worker D61 in the I / O room 59 adjusts so that the output signal of the pressure gauge in the I / O box 52 indicates the adjustment value. At that time, ECR
The worker E62 at 60 confirms that the value of the pressure gauge on the screen, which is the display unit of the vessel DCS53, indicates an adjustment value. Communication between the three workers is made wirelessly. As described above, the workers are arranged at three places at the same time, and the adjustment work is performed jointly by radio. For this reason, there are problems that it is necessary to cooperate well with three people, it takes time, and it takes time and labor.

Therefore, in the present invention, the point that the worker C50 who is the WPC mounting worker 1 performs the work of three persons collectively by one person is different from the conventional method. The WP
The adjustment and inspection work by the C mounting worker 1 is performed according to the following procedure.

First, in FIG. 8, the worker C50 receives the worker C WPC 50- via the wireless section 2-2 of the worker C WPC 50-1 (FIGS. 1 to 3) that he / she wears.
1 establishes communication between the ship DCS 53 and the I / O box 52 via the onboard LAN 54.

Next, the worker C50 enters the WPC for worker C.
Ship DCS53 and I / O from radio unit 2-2 of 50-1
A request is sent to the box 52 via the ship LAN 54, and the current pressure value of the pressure gauge, which is the measuring device to be adjusted this time, which is recognized by each device, is obtained from each device. The worker C WPC 50-1 changes this pressure value during the operation.
Received continuously. Then, the value is referred to as W for worker C.
It is displayed on the HMD 7 of the PC 50-1.

Subsequently, the worker C50 places the pressure gauge (which is a measuring device to be adjusted) at hand (which is a device for adjustment) on the pressure gauge at hand.
A pressure generator is attached, a predetermined pressure for pressure calibration (adjustment) is generated, and a pressure value (a measured value) of a pressure gauge is adjusted. The pressure gauge outputs the adjusted pressure value (adjusted value) by the adjustment by the pressure generator.

At the same time, the worker C50 sets the HMD7
Above, the pressure value recognized by the I / O box 52 and the pressure value recognized by the ship DCS 53 are confirmed. When there is a difference between each pressure value and the adjustment value, the mouse 11 and the wrist keyboard 5 of the worker C WPC 50-1 are used.
Using 2, the pressure value adjusted on the HMD 7 is corrected and input.

The signal of the corrected input pressure value (measured value) is output from the radio unit 2-2 by radio communication, and the LA
N54, I / O box 52 and ship DCS5
3 is sent. Then, the I / O box 52 and the ship DCS 53 adjust (calibrate) the pressure value recognized by each.

With the above operation, the pressure value on the pressure gauge, I
Pressure value recognized by the / O box 52 and the ship DCS5
Three of the pressure values recognized at 3 are adjusted and matched. Then, the adjustment of one pressure gauge is completed.

Since the adjustment work is performed for many measuring instruments, it is important to check the inspection work quickly and shift to the next work. That is, after the work is completed, the worker C
Is stored in the work management server 5 on the worker C WPC 50-1.
6, the adjustment work record format is read out, the adjustment work record is input by a list keyboard or voice input, and output to the work management server 56. This allows the work manager to grasp the progress of the work process in real time. The operator can also save the trouble of inputting the adjustment work record again after one day's work. The worker C5
In the case of 0, the work process table is read, the process is confirmed, and the next work can be promptly performed.

In the inspection work, the worker C WP
Using C50-1, an electronic work manual, which is work information, is called from the work management server 56, and while checking the voice guidance of the electronic work manual with the headphones 9, it is possible to perform an inspection work based on the guidance.

The above operation is performed by the WPC 50 for the worker C.
Using the voice recognition function of -1, it is also possible to execute each operation / work by voice command input and numerical value input using the microphone 10. In particular, in the above case, while operating the pressure generator, confirming the pressure values recognized by the ship DCS 53 and the I / O box 52, and changing those values, the situation in which both hands are occupied may occur. Since it is possible, the voice recognition function is effective.

Up to now, this operation has been performed by three persons at three locations in a coordinated manner as described above. However, the present invention allows one person to perform this operation. As a result, there are tremendous effects such as a reduction in instruction transmission time by wireless communication, an improvement in work quality by eliminating mistakes in listening, a reduction in the number of workers, a reduction in the construction period, and a reduction in cost.

Such operations are not limited to calibration of pressure gauges, but also include adjustment of various measuring instruments and instruments, connection of cables to terminal boards, and operations related to piping while looking at the piping management system drawings. The present invention can be similarly applied to an on-site management operation of an apparatus using an apparatus item detail database. That is, by bringing the WPC to the site, it is possible to obtain the same effect as at the site by grasping information at a plurality of points by one person and simultaneously performing work at a plurality of points. Also, at the site, various information such as drawings, tables, design data, etc. of the upstream system can be referenced in real time, and on the contrary, it is possible to digitize the site information in real time and send it to the upstream system Become.

Although the present embodiment shows an example of inspection of equipment on a ship, not only the case of a ship but also coordination between a plurality of points when inspecting equipment such as a power plant or a chemical plant. The present invention can be similarly applied to a case where there is equipment that needs to perform adjustment work.

(Embodiment 3) A third embodiment of the on-site support system according to the present invention will be described with reference to the drawings. In the present embodiment, an example of application of the present invention to on-site support for grasping the luggage situation of a crane driver in a luggage moving operation using a large crane (such as a large group block crane) will be described. However, the present invention can be applied not only to a large crane but also to a work performed at a remote location without directly viewing the work (a work performed by a worker, which is difficult for the worker to visually recognize).

In operations such as loading and unloading and moving of cargoes and large members with a large crane, since the cargoes and large members attached to the crane are located away from the crane operator's seat, the crane operator can directly observe the situation. It is difficult to do. Therefore, usually, a worker at a loading / unloading site wirelessly communicates the status of luggage and large members, and a crane operator operates the crane while referring to the information.
However, depending on the situation, there may be situations where it is difficult to explain in words, and there are often situations where work is hindered.

In the present invention, when performing operations such as loading and unloading and moving cargo and large members with a large crane,
It is assumed that the crane operator wears the WPC. on the other hand,
A worker at the unloading site carries a handy CCD camera or the like (WPC can be attached) and photographs the situation. Then, the operator transmits the image to the crane operator's WPC using the wireless LAN. The crane driver works while referring to the image and communicating wirelessly. In this way, the crane operator can accurately judge the situation and perform an accurate crane operation.

The configuration of the third embodiment of the on-site support system according to the present invention will be described with reference to FIGS. 1 to 3, FIG. 9, and FIG. 1 to 3 show a WPC mounting worker 1 and the WPC equipment (WPC main body 2 to cable 13).

FIG. 10 is a configuration diagram for explaining an operation site of a large crane. The crane 77 is a large crane such as a large block crane. It is used for moving luggage such as containers, large members, and assembling large structures. Since the crane is large, the operator F70, who is the operator of the crane 77, cannot directly look at the luggage, the members, and the like, and even if it can do so, it looks very small and it is not easy to grasp the details.

The worker F70 is the operator of the crane, and is the WPC mounting worker 1 wearing the WPC.
The crane 77 is operated to move luggage and members. At that time, an explanation of the situation by radio from workers (G, H, etc.) at the unloading work site and reception via wireless LAN,
An appropriate operation is performed based on the image displayed on the HMD 7 of the WPC.

The crane operation room 76 is a room for operating the crane on the crane 77, and the operator F70 operates the crane 77 here. In the case of a large crane, the crane operation room 76 is often separated from the loading / unloading work site.

The worker G71 is a confirmation worker for confirming the status of the load and the members. In addition, the worker G71,
The worker 1 who is a WPC wears the situation of the luggage with the HMC 8, outputs the image to the worker F70 by wireless LAN, and transmits the situation by voice.

The worker H72, like the worker G71, is a confirmation worker for confirming the status of the package, and is a WPC.
It is also the mounting worker 1. In addition, a camera 73 (to be described later) is provided, which captures the situation of the luggage and members, and transmits the captured image to the worker F70 via a wireless LAN via WPC. The photographing is performed while communicating with the worker G71 wirelessly as needed.

Further, the worker G71 or the worker H72.
Here, two workers are shown,
It is not necessary to have only two persons, and it is possible to allocate more personnel depending on the situation.

The load 75 is a load or a member for assembling a large structure which is unloaded by a crane operation.

Next, the operation of the third embodiment of the on-site support system according to the present invention will be described with reference to FIGS. 1 to 3, FIG. 9, and FIG. In the present embodiment, a description will be given by taking as an example the work of loading and unloading luggage and large members by a large crane 77, but the present invention is also applicable to other work at a remote point without directly viewing the work. It is possible.

The loading / unloading operation of a load or a large member by the large crane 77 is usually performed by the following process. In FIG. 10, here, the worker F70, the worker G71, and the worker H72 do not wear the WPC and do not use the camera 73. First, luggage 75
At the unloading site, the worker G71 and the worker H7
A plurality of workers such as 2 are arranged. The luggage 75 is attached to the wire of the crane 77 by the joint work of the worker and the worker F70 who is a crane driver.
The worker F70 moves the luggage 75 to a predetermined place by the crane 77, and lowers the luggage to the predetermined place by the joint work with the worker. When carrying out the joint work, the load 75 attached to the crane is located at a position away from the crane operation room 76, so that the worker F who is the crane operator is
It is difficult for 70 to directly recognize the situation. Therefore, usually, the worker G71 and the worker H72 on the site,
The status of luggage and large items is communicated by wireless voice information,
The operator F70, who is a crane operator, operates the crane while referring to the information. However, depending on the situation, there may be situations where it is difficult to explain in words, and there are often situations where work is hindered.

Therefore, in the present invention, the worker F70, the worker G71, and the worker H7 which are the WPC mounting workers 1 are used.
2 wears a WPC, captures images related to unloading work related to the work, and uses the images to
The operation of the crane and the work related to the crane are different from the conventional method. It is performed according to the following procedure.

First, in FIG. 10, a plurality of workers such as a worker G71 and a worker H72 are arranged at a loading / unloading work site of the baggage 75. And the crane 77
The operator F70, the operator G71 and the operator H72, who are the workers at the work site, are equipped with the worker F WPC 70-1 and the worker G WPC 71-1.
And, the communication by the LAN 74 is mutually established via the wireless unit 2-2 of the worker H WPC 72-1 (FIGS. 1 to 3).

Next, the packages 75 are transferred to the workers (G,
H) is attached to the crane 77 wire by the joint work of the crane operator F70. At this time, the worker G71 and the worker H72 request the worker G70 to use the image captured by the HMC 8 of the worker G WPC 71-1 and the worker H WPC 72-1 or the camera 7
3 is transmitted to the LAN 74 via the wireless unit 2-2.
It is transmitted to the worker F WPC 70-1 via Worker F
The images received by the WPC 70-1 for
Displayed on D7. The operator F70 adjusts the position at which the hook of the crane 77 is lowered with reference to the image. The worker F70 simultaneously receives radio (voice) from the worker G71 and the worker H72 via the wireless unit 2-2 of the WPC.
Work is performed using information (normal wireless communication is also possible).

[0153] The luggage 75 is lifted and moved to a predetermined place.
This is basically the same when the user lowers to a predetermined position. That is, at the request of the worker F70, the worker G71 and the worker H72 can copy the image captured by the HMC 8 of their own WPC or the image captured by the camera 73 via the LAN 74 via the wireless unit 2-2. It transmits to the F WPC 70-1. The worker F70 uses the crane 77 based on the image received by the worker F WPC 70-1 and displayed on the HMD 7.
Perform the above operation. At the same time, the worker F70 is
1 and the wireless (voice) information from the worker H72. Then, the cooperative work with the worker lowers the package to a predetermined place.

Since the worker F70 uses both hands to operate the crane 77, the WPC 70-1 for the worker F is used.
The operation to project the image sent to the HMD7 is WP
The voice recognition function of C is used. That is, the image is selected by voice (whether the image is from the worker G WPC 71-1 or
Or the image from the worker H WPC 72-1) or the image can be enlarged. Worker G71
However, it is desirable to be able to use both hands for the safety of work, so it is desirable to be able to use the voice recognition function. That is, photographing of an image is performed by a command by voice input. Make sure that the latest images are sent as appropriate. Since the worker H72 also covers one hand with the camera, it is desirable that the worker H72 can use the voice recognition function for the safety of the work. This case is the same as the worker G71.

Until now, the worker F70, who has been performing the crane operation by using only voice information, can clearly and clearly recognize the state of the baggage 75.
7 can be performed. In other words, there are very significant effects such as improvement of work efficiency, shortening of construction period, reduction of cost, and improvement of safety by reducing burden on workers on site.

Such a work is not limited to a large crane, but applies to any work in which the operator who operates the apparatus needs to operate while looking at the display.
In this case, by bringing in the WPC, it is possible to read out images from a plurality of cameras by a voice recognition function as needed, exchange images on the screen one after another according to the situation, and operate the apparatus. That is, it is possible to perform the work by properly and accurately recognizing the work without depending on the situation of the work place or depending on the experience.

(Embodiment 4) A fourth embodiment of the site support system according to the present invention will be described with reference to the drawings. The present embodiment describes an example of application of the present invention to on-site support for rocket equipment and equipment maintenance / inspection work performed at a rocket launch site with reference to a huge and complicated material. However, the present invention can be applied not only to rockets but also to the maintenance and inspection of equipment (ships, aircraft, power plants, chemical plants, gas turbines, etc.) performed with reference to vast and complicated materials. It is possible.

For a huge and complicated device such as a rocket, the assembling, maintenance and inspection work requires a large number of steps and must be performed very accurately without error. On the other hand, due to technological innovations related to rockets, the number of updates and revisions of documents has been large and large, and workers involved in assembly, maintenance, and inspection have to refer to vast and complicated documents each time. It is necessary to proceed.

On the other hand, since there are not many materials that can be brought to the site, it is necessary to go to the materials as many times as necessary. Also, when trying to obtain information by wireless inquiry from the site, it may be difficult to quickly find the necessary information, or it may not be possible to accurately grasp the information because of only voice information, which is a big problem for workers. It is a burden. Also, it is necessary to have a work procedure checker in order to eliminate work errors, and it has been difficult to reduce the number of workers and to significantly improve work efficiency.

In the present invention, the WPC mounting worker

By accessing the design data, it is possible to display necessary information on a WPC display while staying at the site. And there is no need to bring a huge amount of manuals and materials to the site. Further, since information retrieval becomes easy, necessary information can be quickly retrieved.
Further, every time one operation is completed, a record of maintenance / inspection can be recorded on the spot, so that there is no omission of recording or entry error, and accurate process management can be performed. The WPC has voice recognition capability and can operate the WPC by voice recognition, so that both hands can use it freely. As described above, the use of the electronic work manual and the voice guidance and the use of the WPC make it possible to improve the efficiency of the work at the launch site of the rocket, thereby shortening the construction period, reducing the number of personnel, and reducing the cost.

FIG. 13 shows the work management server 8 of the launch site R92.
3 shows the relationship between various management servers located in other places. Since launching a rocket is a very large project, it is necessary for several related sites to work together in cooperation. Therefore, a plurality of management servers are connected to each other. Here, a description will be given of the management servers at the four locations of the launch site R92, the support site P93, the support site Q94, and the launch site S95, and the databases belonging thereto.

The support place P93 is a support section for managing a project. Support location P management server 97 as a work management server at a remote location and support location P belonging thereto
The management database 98 is a system belonging to a support place P93 that manages a project. These hold all the data related to the rocket, and also hold all the inspection and maintenance information at each launch site and the inspection and maintenance progress information. It also holds all information about the project and is used to control the entire project.

The launch site R92 is a place for assembling equipment, basic parts, and products assembled up to an intermediate stage to complete a rocket. And finally, launch the rocket. The work management server 83 and the work management database 84 belonging to it are systems belonging to the launch site R92. These functions are as described above. The launch site S95 is also a place where devices, basic parts, and products assembled up to an intermediate stage are assembled to complete a rocket. And finally, launch the rocket.

The launch site S work management server 101 as a remote site work management server and the launch site S work management database 102 belonging thereto are systems belonging to the launch site S95. Basically, it has the same functions as the work management server 83 and the work management database 84 of the launch site R92.

The WAN 103 has a support place P93 and a support place Q
The network connects servers 94, launch site R92, and launch site S95. Although it is possible to use the Internet, there are many cases where higher speed, confidentiality, and reliability are required. Therefore, an ordinary dedicated line or a dedicated line using the satellite communication 96 is usually used.

Next, FIG. 14 will be described. FIG. 14 shows the approximate positional relationship among the above-mentioned support place P93, support place Q94, launch range R92, and launch range S95. The support area P93 and the support area Q94 are in Honshu. The launch site R92 is located in the southeastern islands of Japan. And
The launch site S95 is located in the islands near the equator on the Pacific Ocean.

The artificial satellite 96 is a communication satellite that supports communication between the above-mentioned support site P93, support site Q94, launch site R92, and launch site S95. Since the launch of the rocket needs to be performed without any mistake in the launch preparation process, the support site P93, the support site Q94, and the launch site R92
(Or launch site S95) performs frequent telecommunications to increase the exchange of information. With this communication system, various tasks are performed by referring to instructions, information, and advice from a distance, even with problems during the work.

The operation of the fourth embodiment of the site support system according to the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. In the present embodiment, the maintenance and inspection work of a rocket will be described as an example. However, not only in the case of a rocket, but also in the maintenance and inspection work of facility equipment performed with reference to a huge and complicated material, the present invention Is possible.

In the maintenance and inspection of the rocket, in the case of the conventional method, the WPC is not used in FIG. In the VAB 88, the worker I80 brings a thick work manual and performs maintenance and inspection work with reference to the work manual. At that time, worker J81
Confirms the work procedure of the worker I80. On the other hand, in the BH 87, the worker L86
3 monitors the status of all the devices of the rocket 90 while monitoring changes in the status of the devices due to the work. At this time, the worker I80 who is actually working does not have a device that can grasp the status of other devices, and
Relying on the memory of zero. Therefore, work that affects other devices is performed while relying on the storage of the status of other devices, and thus there is always a concern that a reduction in work efficiency, a work error due to a wrong memory, or the like may occur. Therefore, a worker J81 who performs work confirmation and a worker L86 which performs work management are indispensable. Also, when a problem occurs in the operation, the worker J8
In some cases, the situation may not always be accurately grasped unless the worker L86 of the B1 87 or BH87 actually looks at it.
Takes a sketch or a photo as necessary, interrupts the work, and transfers the sketch or the photo to the worker J81 or the worker L86.
Need to be confirmed by

Therefore, in the present invention, the worker I80 and the worker J81 become the WPC-mounted worker 1 by
A large-volume work manual is obtained as an electronic work manual from the work management server 83 via the HD of the WPC main body 2 or the wireless LAN, displayed on the HMD 7 of the WPC, and performing the work while referring to the work manual. The status of each device of the rocket is determined by the WPC as needed by the work management server 83.
From the wireless LAN, and displaying the information on the HMD 7, it is possible to accurately grasp the status of other devices in operation. Therefore, the possibility of erroneous operation of the device is greatly reduced.
In addition, when a problem occurs in the work, the situation is photographed using the HMC 8 and transmitted to the worker J81 or the worker L86 of the BH87 via the wireless LAN, so that a quick understanding can be obtained and a quick response can be obtained. It is possible to take measures.

In FIG. 12, the worker I8 at the launch site R92
0 performs maintenance and inspection work of the rocket 90. First,
At the start of the maintenance / inspection work, a worker who performs maintenance / inspection work of the rocket (here, worker I80) is preparing for the following. WPC shown in FIGS. 1-3
Is connected to the work management server 83 via the LAN 85 shown in FIG. 11 via the wireless unit 2-2 of the WPC. The work management server 83 is connected to the work database 84 and is in a state where such information can be extracted at any time. In addition, the WAN 103 can be connected to the management servers (97, 99, 101) of other places (support place P93, support place Q94, launch site S95) as needed.

At the time of maintenance and inspection, WPC 8 for worker I
0-1 (FIGS. 1 to 3) transmits a request for information (work information such as an electronic technical manual, specifications, drawings, and design data) required for the work to the work management server 83 from the wireless unit 2-2. Output via communication. The work management server 83 is a LAN 85
Receive that request via. Then, in response to the request, the information is acquired from the work management database 84, and information (work information) necessary for the work is output to the worker I WPC 80-1. WPC80-1 for Worker I
Transmits information necessary for the operation to the wireless communication unit 2 via the LAN 85.
-2 and stored in the storage unit 2-3. Note that the work of acquiring information necessary for the work from the work management server 83 before the work can be performed in real time during the work.

During the operation, the worker I80 operates his own WPC.
Necessary information such as an electronic work manual is read from the HD of the main body 2 (when downloaded in advance) or the work management server 83, and displayed on the HMD 7. And HM
According to the instructions on the screen of D7, maintenance and inspection work is performed.
Since the worker I WPC 80-1 is used, both hands are free, and the work can be executed reliably and efficiently. In addition, since the operation is performed while reading the electronic operation manual, the operation can be performed accurately without any operation error. Furthermore, it is also possible to make the electronic work manual proceed by voice guidance. An image is captured by the HMC 8 as necessary.

When the work is completed, the work completion record is input, and the work management server 83 (or the worker I) is input.
To the HD of the WPC body 2 of the WPC 80-1. Since the work record created at the work site can be used as a record as it is, the trouble of re-input and entry mistakes due to later entry can be eliminated. In the work management, the progress of the work can be grasped in real time.

At the maintenance stage, when it is desired to compare with the past situation or to refer to another drawing or design data, the work I of the work management server 83 is performed by the worker I WPC 80-1. The related maintenance data stored in the management database 84 is accessed and necessary data is read. Then, it is displayed on the HMD 7 and used as a reference for the work. In that case, information to be taken out (information on maintenance and inspection)
Is obtained not only from the work management database 84 of the work management server 83 of the launch site R92 but also to other support points P93 and Q connected to the WAN 103 as shown in FIG.
94, each management server (97, 99, 1) at the launch site S95
01) can also be read. HMD7 in real-time or near real-time with high-speed communication
Can be displayed above.

At the time of maintenance and inspection, the worker I80 and the worker K82 (skilled worker) and the worker I
Communication is possible by communication between 0-1 and WPC 82-1 for worker K. Therefore, even if the worker K82 is not near, the advice can be received. Worker I
Since the image of the repaired part can be photographed on the spot by the HMC 8 and transmitted via the LAN 85 to the worker K82 at a remote position, the worker K82 can also grasp the situation accurately, and Can provide guidance.
The worker K82 is in another support area P93, Q94, launch site S95
Communication can be performed via the WAN 103.

Note that the above-mentioned operations can be executed by voice guidance, voice command input, and numerical value input, using the voice recognition function of the WPC. In particular, in the above case, since the maintenance and inspection is performed while reading the electronic technical manual, there may be a situation where both hands are occupied, so that the voice recognition function is effective.

Heretofore, this operation has been performed by three persons at three locations as described above, and has been performed in a coordinated manner such as work-confirmation-management. The worker J81 who has been checking and the worker L86 which has been managing the workers I80 and J81 are not particularly necessary. That is, the above operation can be performed by one person. As a result, there are tremendous effects such as a reduction in instruction transmission time by wireless communication, an improvement in work quality by eliminating mistakes in listening, a reduction in the number of workers, a reduction in the construction period, and a reduction in cost.

Such a work can be used for all maintenance and inspection work. By bringing the WPC to the site, various information such as drawings, tables and design data of the upstream system can be referenced in real time at the site. And send it to the upstream system. As a result, the progress of the work can be grasped in real time, and accurate process management can be performed.

(Embodiment 5) A fifth embodiment of the site support system according to the present invention will be described with reference to the drawings. This embodiment describes an example of application of the present invention to on-site support for maintenance and inspection of aircraft equipment and equipment performed with reference to huge and complicated materials in aircraft maintenance. However, the present invention can be applied not only to aircraft, but also to maintenance and inspection work on equipment (ships, rockets, power plants, chemical plants, gas turbines, etc.) performed with reference to vast and complicated materials. It is possible.

In a large and complicated device such as an aircraft, the assembling, maintenance and inspection work requires a large number of steps and must be performed very accurately without error. On the other hand, the technology is changing rapidly, the aircraft is constantly improving, and maintenance is becoming more complicated. As a result, technical documents have been updated and revised many times and in large quantities, and workers involved in assembly, maintenance and inspection have to refer to vast and complicated materials each time.

However, since there are not many materials that can be brought to the aircraft maintenance site, it is necessary to go to the materials as many times as necessary. Also, when trying to obtain information by wireless inquiry from the site, it may be difficult to quickly find the necessary information, or it may not be possible to accurately grasp the information because of only voice information, which is a big problem for workers. It was difficult to significantly improve work efficiency due to the burden.

Is checked.

[0220] If an abnormality is found during the inspection, the content of the abnormality is notified by the worker M110 to the WP for the worker M.
The data is transmitted from the C110-1 to the work management server 114 via the LAN 113. Alternatively, the work management server 114 may determine an abnormality based on the check contents. Then, the work management server 114 immediately transmits an electronic work manual regarding the corrective measures to the worker M WPC 110-1 via the LAN 113. The worker M110 performs a corrective action based on the information (S304).

When all the inspection items have been inspected, the inspection ends (S306). The worker M110 is a worker M WPC.
A work report is created on the spot by using 110-1, and the work report is transmitted to the work management server 114 via the LAN.

The maintenance is performed in the same process as the inspection. In the inspection / maintenance stage, when it is desired to compare with the past situation or to refer to another drawing or design data, the work management database 115 of the work management server 114 is transmitted from the worker M WPC 110-1. Access related inspection / maintenance data stored in the system and read out necessary data. Then, it is displayed on the HMD 7 and used as a reference for the work.

Further, even if a skilled worker is not in the vicinity at the time of maintenance / inspection, the skilled worker (supporter) has the supporter WPC 111.
It is possible to receive the advice using the worker M WPC 110-1. Since the worker M110 can photograph and transmit the image of the repair location on the spot to a skilled worker (supporter) at a remote position, the skilled worker can also accurately grasp the situation, and Can provide guidance.

[0224] The above-mentioned operations can be performed by voice guidance, voice command input, and numerical value input using the voice recognition function of the WPC. In particular, in the above case, since the maintenance and inspection are performed while reading the electronic technical manual, there may be a situation where both hands are occupied, so that the voice recognition function is effective.

Such a work can be used for all maintenance and inspection work. By bringing the WPC to the site, various information such as drawings, tables and design data of the upstream system can be referenced in real time at the site. And send it to the upstream system. As a result, the progress of the work can be grasped in real time, and accurate process management can be performed.
And improve work quality, reduce the number of workers, shorten the construction period,

In an apparatus having a complicated structure and a large number of parts, such as a membrane LNG ship, the number of manufacturing and inspection steps and check items are enormous. Moreover, since high-precision manufacturing is required, it is necessary to perform the process very accurately and without error. Usually, the manual of the work is on paper, and the check of the work process is performed on site using the paper. However, when using paper, the manual is large in volume and easily obstructed, and it is impossible to see it while working. Necessary items are not always found immediately. On the other hand, in the case where paper is used for checking a work process, it is difficult to completely prevent human error, and unconfirmed items or unchecked items may remain. However, it is difficult to find them on site, and they are often found by rechecking the paper after the work is completed. In that case, go to the site,
Re-examination may be required in some cases, which is twice as troublesome. These situations are heavy burdens for the workers, and it is difficult to greatly improve the work efficiency.

According to the present invention, the WPC mounting worker
Manufacturing and inspection work shall be performed. By doing so, the worker accesses the electronic work manual, drawings, and design data on the database during the work, and displays information necessary for the manufacturing work on the display of the WPC while staying at the site, or Voice guidance can be provided. In addition, since the work process is checked on the screen of the WPC, the WPC immediately detects and issues a warning when there is a recording omission or an inspection error. Therefore, there is no mistake in checking the work process, and accurate process management can be performed. In addition, the WPC has voice recognition capability and can operate the WPC by voice recognition, so that both hands can be used freely. In this way, the use of electronic work manuals, work process check procedures, etc., and the use of WPCs make it possible to increase the efficiency of work in the manufacture and inspection of membrane LNG ships, shortening the construction period, reducing personnel, Cost reduction becomes possible.

502). The display is displayed in order from the first procedure.

Next, the inspector 121 performs an inspection operation in accordance with the electronic operation manual, and checks the check list every time one inspection is completed. The result of the check is input on the touch panel 5-1 (S503). Until there are no more inspection items in the electronic work manual, S502
And the process of S503 is repeated (S504).

At the stage where all inspections have been completed according to the electronic work manual, check list data is saved (S505). Then, the data of the checklist is transmitted from the wireless unit 2-2 of the inspector WPC 121-1 to the work management server 122 via the LAN 124 by wireless communication.

Check if you have forgotten to check or skipped the work.
Work management server 12 that received checklist data
2 performs a check at that stage. If the user forgets to check or skips the work, the work management server 122 immediately gives an instruction to that effect, and the LAN 124
Is sent to the inspector WPC 121-1 via the. Therefore, the inspector 121 can immediately start over.

At this stage, when performing the next inspection,
The work management server 122 transmits the next inspection instruction (location, inspection content, etc.) to the inspector WPC 121-1 via the LAN 124. The inspector 121 is the inspector WPC 12
The next inspection is performed according to the instruction of the next inspection received in 1-1. In this case, the work management server 122 determines the necessary inspection items from the information on the next inspection work process and location code, and stores the electronic inspection procedure manual and the checklist relating to the inspection items in the inspector WPC 121-1. Send to Further, the inspector 121 can call the work schedule from the work management server 122, and the inspector 121 can determine based on the work schedule.

[0256] The above-mentioned operations can be executed by voice guidance, voice command input, and numerical input using the voice recognition function of the WPC. In particular, in the above case, since the production and inspection are performed while reading the electronic technical manual, there may be a situation where both hands are occupied, so that the voice recognition function is effective.

Such operations can be used for all manufacturing and inspection operations. By bringing the WPC to the site, various information such as drawings, tables and design data of the upstream system can be referenced in real time at the site, and on the other hand, real-time information of the site and manufacturing / inspection records can be obtained in real time. It can be digitized and sent to upstream systems. As a result, the progress of the work can be grasped in real time, and accurate process management can be performed. In addition, there are tremendous effects such as improvement of work quality, reduction of workers, shortening of construction period, and cost reduction. The present invention is also applicable to on-site work assembly and maintenance support for other shipbuilding.

(Embodiment 7) A seventh embodiment of the on-site support system according to the present invention will be described with reference to the drawings. In the present embodiment, an example of application of the present invention to on-site support in process evaluation in manufacturing cost evaluation during ship manufacturing will be described. However, the present invention can be applied to other sites that require a process evaluation by an operator.

In the evaluation of the production cost in the production of a ship, it is important to divide the blocks in the production process and to carry out the construction method in each block. In studying the construction method for each block, it is important to estimate the number of work steps for each operation in the block. In estimating the number of work steps, it is necessary to generate a highly reliable sequence model (standard continuous work). Generation of sequence model
In the field, an observer observes the worker's work, measures time with a stopwatch, makes notes, and summarizes the results. However, this method has a problem that it takes time and effort.

In the present invention, regarding the generation of a sequence model, the WPC mounting operator becomes an observer, and the results of observation at the work site are sequentially converted to a server (or WPC H).
D). The server (or WPC) estimates the number of work steps based on the received result, and automatically generates a sequence model. By doing so, the observer can easily generate a reliable sequence model with only simple input to the WPC without using notes or stopwatches. Then, it can be used for evaluation of manufacturing.

The construction of the seventh embodiment of the on-site support system according to the present invention will be described with reference to FIGS.
This will be described with reference to FIG. 1 to 3 show a WPC mounting worker 1.
And its WPC equipment (WPC body 2 to cable 13)
It is. The WPC mounting worker 1 is an observer who generates a sequence model. When generating a sequence model, work is performed by effectively utilizing the functions of the WPC. In the present embodiment, voice recognition input is possible in the WPC main body 2, and voice input is performed using the microphone 10. A wrist keyboard 5-2 is used as the input device 3. The function of each configuration is described in (A) Outline of WPC, and
(B) As described in WPC Details, the description is omitted.

FIG. 23 shows the relationship between the WPC mounting worker 1 and servers involved in inspection and maintenance. Observer WP
C130-1 is a WPC of the observer 130 involved in an observation operation for generating a sequence model. The above-mentioned (A) WPC outline shown in FIGS. 1 to 3 and (B) W
It has the functions described in PC details. A work management server 132 (to be described later) and a LAN 131
(Described later). The observer 130 uses the observer's WPC 130-1 to electronically input an observation record, transmits the observation record to the work management server 122, and records the observation record.

The work management server 132 is a server that performs information processing for automatically generating a sequence model.
It performs data reading, writing, searching, and data processing related to automatic generation of a sequence model with WPC, and supports automatic generation of a sequence model. Data is,
The data is stored in the work management database 133, searched and taken out as needed, and new data (automatically generated sequence model) is stored in them. Further, in response to an inquiry from the observer 130 about information and data on manufacturing cost evaluation and process evaluation, the data is output.

The work management database 133 is a database having data relating to automatic generation of a sequence model. Also, information and data relating to manufacturing cost evaluation and process evaluation and new data (automatically generated sequence models) are stored.

The LAN 131 is a LAN that connects the work management server 132 and the WPC. Work management server 132
Can be connected to a network either by wire or wirelessly.
On the other hand, the WPC side has a wireless LAN due to its portability and workability.
Make the connection. It is also possible to connect using a PHS or mobile phone function. Although the connection is made on the LAN 131 here, the connection can be made by other networks or direct connection. The worker O13
4 and the observer 130 are selected for the description of the present embodiment, and the work is not necessarily performed by two persons, but is performed by a plurality of workers.

FIG. 23 shows a method of generating a sequence model by work observation. The worker O134 is a worker who performs sample work for generating a sequence model. Perform tasks such as parts handling, tool use, and mechanical handling. The observer 130 is the WPC mounting worker 1. The operation of the operator O134 is observed from behind, and the operation is divided into basic operations.
The work of recording on 0-1 is performed.

Here, the MaxiMost method used for automatically generating a sequence model will be described. Ma
The xiMost method is one of predetermined time standard (PTS) methods for estimating the number of work steps. For example, the worker O134
However, consider the task of walking 16 steps, bending the waist, and putting tape in the tool box. This operation is composed of a sequence of three actions: walking (action walking): A-bending the waist (movement of the torso): B-inserting (removing parts): P. In addition, each time is defined as 1 mHour = 3.6 seconds as one unit (hereinafter referred to as “1 TMU”), walking (action walking): 3 TMU (10.8 seconds) −bending the waist (torso movement): 1 TMU ( (3.6 seconds) -insert (part removal): 1 TMU (3.6 seconds), for a total of 5 TMU (18 seconds). This is expressed as follows. A3B1P1
(*) By using such a simple description method, it is possible to easily and accurately record the observation of the work performed by the operator at the site by the observer.

Next, a sequence model of the MaxiMost method will be described. The sequence model is a model of a certain fixed operation that is often executed in an actual work site, as represented by the above equation (*). In FIG.
Five sequence models are shown. First, the meaning of a symbol representing an individual operation (SubActivity: SA) will be described. The following three meanings (SA) are shown in the upper three parts of the figure, namely, part handling (ABP), tool / device use (ABT), and mechanical handling (ABM). ε: Move to the first working position. A: Action walking B: Trunk movement P: Part removal / positioning T: Tool / device use, M: Machine handling, device use For crane transportation (ATKTPTA), the following meaning (S)
A). ε: Move to the first working position. A: Action T: Conveyance K: Sling, removal of balls P: Positioning of target object The following meaning (SA) is expressed by conveyance by a transport vehicle (ASTLTLTA). ε: Move to the first working position. A: Action walking S: Start and stop T: Transport, L: Loading or unloading The numbers in the circles indicate the actual time taken (the numbers in the figure are simply numbers).

Many operations can be represented by the above-described five basic sequence models, and the observer 130 may actually measure the time and fill in the numbers in the circles. In addition, when there is a work that cannot be expressed by the basic sequence model, the observer 130 creates another new sequence model from the observation result.

The operation of the seventh embodiment of the site support system according to the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. At the stage of starting the observation operation, the observer 130 who is performing the observation operation is preparing for the following. The WPC shown in FIG. 1 to FIG. 3 is attached, and the LAN 131 shown in FIG.
It is connected to the work management server 132. The work management server 132 is connected to the work database 133 and is in a state where such information can be extracted at any time.

Referring to FIG. 26, in the observation operation, observer 130 observes the operation of operator O134 (FIG. 24) in order to create a highly reliable sequence model in estimating the operation man-hours. (S601). Then, the observer 130 is made to correspond to one operation of the worker O134, and every time a new operation is entered, the above-described SA (ε, A, B, P,
T, M, S, L) and select one from
30-1 (S602).

The WPC for observer 130-1 is the same as the previous SA.
From the input time of the operator O1 and the input time of the current SA,
The operation time of the previous SA by 34 is calculated and displayed.
For example, if the previous SA is B and the current SA is T, when T is input, B is calculated from the time when T is input.
Is subtracted, and the difference is
(For example, 3TUS)
... B3T is displayed (S603). Then, the observer WPC 130-1 determines the sequence of the observed SA,
By comparing the above five basic sequence models (FIG. 25), it is determined whether or not a basic sequence model exists. If there is no such basic model, it is newly registered as a unique new sequence model. Then, when the observation of one work is completed, a set of sequence models representing the work (sequence of the work) is completed (S604).
And the sequence of the completed work is W
LAN1 by wireless communication from wireless section 2-2 of PC 130-1
It is transmitted to the work management server 132 via the server 31.

The process for obtaining the sequence of the entire work is performed by the observer's WPC 130-1 by the radio unit 2-.
According to 2, it is also possible to perform the processing while communicating with the work management server 132 via the LAN 131 in real time by wireless communication.

As described above, when the sequence for each work is determined, the work time is determined at the same time.
Then, in the manufacture of a ship that is a collection of these, what kind of sequence is used and how much, how much work time and how much should the worker's estimate be,
This makes it possible to evaluate the cost of a ship.

(Eighth Embodiment) An eighth embodiment of the site support system according to the present invention will be described with reference to the drawings. This embodiment is based on the WP at the time of manufacturing a membrane LNG ship.
An application example regarding improvement of the user interface when C is used will be described. However, the present invention is also applicable to a WPC used in a ship or other manufacturing work site using another WPC.

When a WPC is used in the manufacture of a ship, a display screen on the HMD is used. As a form of use, when it is desired to display a drawing, an image, or a table (hereinafter, referred to as “drawing etc.”), if the size is small, the whole fits in the display screen. It is difficult. Even if it is stored, it is impossible to determine a detailed portion because the reduction rate becomes large. A similar situation can occur when a plurality of drawings and the like are to be displayed side by side. In addition, if a drawing or the like is enlarged to display a detailed portion, it is difficult to grasp the position of the entire drawing. Sometimes it becomes difficult.

In the present invention, a user interface for viewing a local area is introduced into the display unit of the WPC while conscious of the whole. Then, the relationship between the whole and the local area is made easy to grasp. By doing so, even at a work site using WPC, even if the display screen is small for displaying drawings etc., the inconvenience is eliminated,
Work can be performed efficiently using WPC.

The construction of the eighth embodiment of the on-site support system according to the present invention will be described with reference to FIGS.
0 and FIG. 1 to 3 show a WPC mounting worker 1 and the WPC equipment (WPC main body 2 to cable 13). The WPC mounting worker 1 is a worker N120 or an inspector 121 who works using a WPC at a manufacturing site of a membrane LNG ship. The user may proceed with the work while displaying the drawings and the like on the HMD 7 and refer to them, or may issue (receive) instructions based on the drawings and the like. The function of each configuration is as described in (A) Outline of WPC and (B) Details of WPC.
The description is omitted.

FIG. 19 shows the relationship between the WPCs of the worker N120 and the inspector 121 who are the WPC mounting worker 1, and the work management server 122 and the like. FIG. 20 is a configuration diagram for explaining manufacturing and inspection work at a manufacturing and inspection site of a membrane LNG ship. These are described in Example 5
Therefore, the description is omitted.

FIG. 27 shows the characteristics of the display on the display screen of the WPC. The display 140 is a display screen that displays drawings and data. In WPC, it is displayed on the HMD7. It is also possible to display on the touch panel 5-1. FIG. 141 is a diagram showing an entire wall on one side of a tank A126 of the membrane LNG ship. When the whole is displayed, the local area is small and it is hard to see. The spider pointer 142 is a pointer for designating a place to be enlarged or reduced. For the operation, once the spider pointer 142 is displayed on the screen (a pull-down menu or a button is prepared on the screen), and the spider pointer 142 is dragged with the mouse pointer (operated with the mouse 11) to a point to be designated. The drag end point is the designated point. The location once enlarged or reduced (previous designated point 147: described later) is stored, and when the spider pointer 142 moves thereafter, a line segment (guide 144: described later) is displayed between the stored location and the spider pointer. . If no operation is performed on the way, the designated point 1
46 and the spider pointer 142 overlap. The designated point 146 is a point (location) at which the operator N120 or the inspector 121 (hereinafter, referred to as “the operator N120 or the like”) designates a point that he or she currently wants to enlarge or reduce with the spider pointer 142. The previous designated point 147 (-1 to 4) is a point (place) where the worker N120 or the inspector 121 has enlarged or reduced in the past (before the designated point 146 is designated) by the spider pointer 142. The designation can be canceled by specifying again and canceling or deleting (pull-down menu, etc.). The detailed view 143 is the overall view 141
It is a figure showing the local part which expanded. Guide 144 (-1 to
7) is a line segment connecting the designated point 146 and the previous designated point 147. The zooming dial 145 is a dial for continuously designating an enlargement ratio or a reduction ratio when enlarging the entire diagram 141 or reducing the detailed diagram 143, and is operated with a mouse pointer.

In FIG. 27A, four previous designated points 147
And one designated point 146 (same position as the spider pointer 142), and shows a situation where these are related by seven guides. When the figure is enlarged in the state of (a), the state becomes (b). The designated point 146 (the same position as the spider pointer 142), which is the current designated point, is associated with the four guides 144-1 to 144-4, so that the position can be easily grasped.

The operation of the eighth embodiment of the site support system according to the present invention will now be described with reference to FIGS.
This will be described with reference to FIGS. At the beginning of the production and inspection work, the production and production of the membrane LNG carrier 125
The worker N120 or the like who performs the inspection work is preparing for the following. The WPC shown in FIGS. 1 to 3 is mounted, and the LAN 124 shown in FIG.
It is connected to the work management server 122. The work management server 122 is connected to the work database 123 and is in a state where such information can be extracted at any time.

Referring to FIG. 27, worker N120 or the like working at the manufacturing site of the membrane LNG ship sends drawings and the like necessary for the work to work management server 122 or his / her own WPC (worker's WPC). WPC 120-1 for N or WPC 121-1 for inspector: WPC 120 for worker N
-1 etc.)) and display it on the HMD 7. At this time, the initial state of the displayed drawings and the like is as shown in FIG.
7 (a) (however, there is no designated point 146, previous designated point 147, and guide 144 yet). The worker N120 or the like designates a designated point with the spider pointer 142 as necessary, and enlarges a drawing or the like near the designated point with the zooming dial 145 (FIG. 27).
(B)).

When the worker N120 or the like wants to check another place in the drawing, the following is performed. While the drawing or the like is being enlarged, the spider pointer 142 currently at the designated point is dragged with the mouse and moved to a point to be confirmed. And spider pointer 14
Specify the point with 2. At this time, since a line segment (guide) extends from the immediately preceding designated point to the moving spider pointer 142, the direction from the immediately preceding designated point can be known without losing the drawing or the like, and the place on the drawing is not lost. Only At this time, the position (coordinates, etc.) on the drawing is indicated by the spider pointer 1
It is also possible to display it beside 42. For example, the lower left of the overall view is (0, 0) and the upper right is (1.0, 1..
The position in the drawing is displayed as 0).

When the number of points designated by the spider pointer 142 increases, the designated point 14 shown in FIG.
6. The previous designated point 147 (-1 to 4) and the guide 144 (-
1 to 7) are displayed. Then, when the designated point 146 is enlarged, it becomes FIG. 27 (b), and the position on the whole figure can be easily grasped from the relation with the guide.

When the operator N120 or the like wants to check another place on the drawing, the operator zooms out the drawing with the zooming dial 145, specifies the point to be checked with the spider pointer 142, and uses the zooming dial 145 to draw a drawing near the specified point. Is again possible. Also in this case, since the functions of the spider pointer 142 and the guide 144 are provided, it is possible to easily grasp the current position of the designated point after re-enlargement. In particular, when there are many places to be enlarged, it becomes a very effective position checking means. Also, the size of the enlargement can be freely changed by the zooming dial 145, and can be selected according to the work situation.

In this way, when a worker or the like uses a WPC, even if a large drawing or the like is displayed on the HMD 7 or another display device attached to the WPC, the whole and the local area can be displayed simultaneously and continuously. Etc. can be reduced. Therefore, the work efficiency is improved, the construction period can be shortened, and the cost can be reduced.

Ninth Embodiment A ninth embodiment of the site support system according to the present invention will be described with reference to the drawings. The present embodiment describes an application example of the present invention to on-site support for ensuring safety at a site where workers perform various operations, such as a manufacturing site of various ships, aircraft, rockets, etc., an inspection / maintenance site, an installation site, and the like. . However, the present invention can be applied not only to the above-mentioned case but also to a place where safety is required for other work.

At sites where workers perform various operations such as manufacturing sites for various ships, aircraft, rockets, etc., inspection / maintenance sites, and installation sites (hereinafter referred to as “various sites”).
Examples of on-site support measures for ensuring safety include various signs related to safety, signs such as signs, protective fences for preventing intrusion, and warnings for notifying danger. They are, in principle, well-known.
However, if one day or at a certain time suddenly enters a no-go area or danger area, or a worker at an adjacent site who is not familiar with the site arrives, or when a work environment is likely to change, It is not always appropriate and effective in some cases.

Also, in the case of a WPC wearer, the display of the HMD may be distracted and the above-mentioned display may be overlooked or the user may pass over the protective fence. In an explosion-proof area,
Even if the PC is not explosion-proof,
May be left on.

In the present invention, on-site support is provided so that a WPC wearer can safely perform work. For example, at various sites, a warning is automatically displayed on the HMD and an alarm is sounded when a worker enters a restricted area or a dangerous area. When entering the explosion-proof area, the power is automatically turned off immediately. It has a gas sensor, detects the generation of toxic gas or lack of oxygen, automatically displays a warning on the HMD, and sounds an alarm. By adding such a function, the worker can safely and safely perform the above-mentioned various dangers. Further, by monitoring the work condition and physical condition of the worker via the WPC, even a single worker can be performed, which can contribute to improvement of work efficiency and cost reduction.

For such a WPC mounting worker 1,
As a site support method for safety, the method can be constructed from the following viewpoints. (1) Working environment The working environment of the worker. This is because safety measures differ depending on the work environment. The environment includes high-altitude work, exposure environment, high and low temperature work, high and low pressure work, noise work, closed work, underwater work, sea surface work, underground work, designated (special) area, and the like. Working environment conditions in that case. The conditions vary depending on the work environment, and there may be cases where work is possible and cases where work is not possible depending on the range of conditions. The condition is
Altitude, radiation dose, temperature, atmospheric pressure, sound / vibration, atmosphere gas composition, specific gas volume, gas flow, water pressure / water quality / velocity, humidity, off-limits areas, off-limits areas other than those wearing special safety gear, at work sites (For example, when a special material or gas is used).

(2) Situation of Worker The judgment regarding safety differs depending on the situation of the worker. The criteria include position information (work area), worker's ability (experience, qualification), worker's work charge (role), worker's work authorization status / level (position), worker's biometric information (heart rate) Number, body temperature, blood pressure, etc.), worker equipment, etc.

(3) Method of Detecting Environment and Situation The method of detecting the work environment and the situation is very important for collecting materials for determining safety. As a method for obtaining environmental information, a measuring instrument is permanently installed in a work area, and a measurement result is constantly transmitted (such as an infrared information generator having a measuring instrument). , And so on. Also, as a method of obtaining the status of the worker, the personal information is obtained from the database of the worker based on the input of the personal ID, the position information is obtained by the GPS / wireless LAN terminal, and the WPC is equipped with a measuring device for measuring the physical condition. Always measure. The specific area is obtained from information relating to the work area in a database holding information regarding the work.

(4) Object When a safety problem occurs, the person who should be notified and dealt with is basically the worker who wears the WPC. There are a WPC mounting worker (within a certain distance), a work manager, a site safety supervisor, a manager at a remote place, and the like.

(5) Countermeasures When a safety problem occurs, a countermeasure for coping with the problem is important. As an example of response measures, WPC
Warning / response instruction, warning / response instruction and WPC function restriction (HMD / touch panel display screen OFF, mouse / wrist keyboard, etc. input prohibition, image capture prohibition, access to server) Prohibition, etc.), turning off the WPC power after the warning / response instruction (the whole WPC), and confirming the warning / response instruction and the physical condition (consciousness / arousal status, heart rate, blood pressure, etc.). The warning content may be, or is likely to cause, a problem in the work environment, such as work at height, presence of toxic gas, excess or deficiency of oxygen concentration, temperature fluctuation, loud noise, entry into a restricted area. Display status. The corresponding instructions include checking safety equipment for working at heights, wearing gas masks and life gem, indoor ventilation, and reading the text aloud (to know the activity of the brain by the ability to recognize and utter normally), Instruct workers to respond to work environment problems such as wearing warm clothing, checking the operation of the temperature controller, wearing earplugs, and quickly leaving.

At the same time, WPs near managers and workers such as site safety supervisors (WPC mounting workers)
A notification to the C-wearing worker and a specific response instruction, an abnormal situation notification and display to the terminal device relating to the work are performed. Managers such as site safety supervisors (WPC installation workers) and WPC installation workers near the workers give appropriate instructions (such as calling out using WPC and checking the situation directly) as necessary. Do.

As measures for safety when using WPC, various safety functions can be provided in consideration of the above five points (1) to (5).

In consideration of the above five points (1) to (5), the following process is carried out as a method of on-site support regarding safety for a WPC mounting worker.
Referring to FIGS. 1 and 31, first, WPC 1-1 checks the work environment where the worker is located (S701).
(Corresponding to (1) and (3) above). For confirmation, WPC1
A connected small and portable measuring instrument, which is the input unit 3 of -1, is used. For example, gas sensors (toxic toxic gases such as oxygen, carbon dioxide, carbon monoxide, chlorine, and silane, combustible combustible gases such as hydrogen and methane, etc.), pressure sensors (barometric pressure, water pressure, etc.), thermometer,
It is a measuring device that measures the working environment, such as an anemometer, vibrometer, acoustic meter, and radiation meter. The measurement is carried out by carrying (or attaching) measuring instruments considered necessary in consideration of the work environment predicted in advance.

The following method is also applicable. A measuring instrument is installed in a target area in advance, and a measurement relating to a certain environment is appropriately performed. Then, the measured value is always transmitted to the area by the wireless communication system using the infrared light of the measuring device. Then, the worker who has entered the area can grasp the environment of the area by receiving it by the wireless unit 2-2 of the WPC 1-1. That is, the same effect as carrying a small measuring instrument can be obtained. As another method, a measuring instrument is installed in a target area in advance, a measurement relating to a certain environment is appropriately performed, and the measurement result is transmitted to a server that monitors a work environment. When the worker enters the area, the measurement result regarding the environment is transmitted from the server recognizing the area via the wireless LAN.
By receiving it by the wireless unit 2-2 of the WPC 1-1,
Understand the environment in that area. That is, the same effect as carrying a small measuring instrument can be obtained. The above information,
It is sent to the control unit 2-1 of the WPC 1-1, where the work environment where the worker is located is confirmed.

Next, the WPC 1-1 checks the situation where the worker is located (S702) (see (2) above).
(Corresponding to (3)). Confirmation includes information of the worker himself / herself entered (position, role, experience, holding qualifications, etc. at the work site), his / her position information to be confirmed on a GPS or wireless LAN terminal, etc. Content,
This is a situation such as a physical condition (heart rate, body temperature, blood pressure, etc.) of the worker.

[0302] The information of the person is input by the person before the work in advance and is held in the storage unit 2-3. However, by simply inputting the ID of the worker, the WPC 1-1 uses the wireless unit 2-2 to automatically access the database in which the data of the worker is held and acquire the necessary data. It is also possible.

[0303] The location information can be obtained by connecting a GPS to the WPC 1-1 and knowing the location information. When the WPC 1-1 uses the wireless unit 2-2 to transmit and receive data via the wireless LAN, which wireless LAN terminal is used. There is a method of detecting whether or not the terminal is used (outputting a signal from the wireless LAN terminal). As another method, a device for transmitting position information of the place to each area (always transmitting position information to the area by a data communication system using infrared rays) is installed, and the user enters the area. The worker puts it in WPC
The environment of the area can be grasped by receiving by the wireless unit 2-1 of 1-1. The WPC 1-1 can also transmit the position information to a server that monitors the work environment.

The contents of the work currently being performed are input by the person before the work in advance. However, if the work process and the worker in charge are set in advance, the I
Based on D, the WPC 1-1 can automatically access the database holding the data of the business process and the worker in charge by using the wireless unit 2-2 to acquire necessary data. It is.

To check the condition such as the physical condition of the worker,
A connected small and portable measuring instrument, which is the input unit 3 of the WPC 1-1, is used. For an operator in a region where the working environment is particularly severe, it is desirable to continuously measure during the entire operation. The above information is stored in the control unit 2 of the WPC 1-1.
1, where the situation where the worker is located is confirmed.

Next, based on the information in S701 and S702, (the control unit 2-1 of) the WPC 1-1 determines whether the worker is in a situation having a safety problem (S703).
In the determination, regarding the environment, the result of S701 and a general work environment standard (official standard value) or a preset work environment standard (standard value set by a company or an organization)

In the determination, the work environment and the situation where the worker is placed are reconfirmed, and it is determined whether or not the response based on the warning / response shown in S704 is completed. It is also possible to simply perform the same determination as the determination in S703. If the safety problem has been avoided, the corresponding action ends, and the restricted function is restored (S706). If it has not recovered, the process returns to S704, and a corresponding action is performed. In that case,
It is possible to repeat the same response measures, and it is also possible to set to take additional response measures such as issuing a stronger warning.

After recovery of the restricted functions, WPC1-1
(The control unit 2-1) determines whether or not the work of the worker is completed (S707). If it has been completed, the safety-related management process for the operation is completed. If not, the process returns to S701 and continues to monitor the safety of the worker.

[0310] Based on the above-described viewpoints, on-site support for safety is provided. If the environment and situation of the work can be predicted in advance (for example, the worker is approaching the restricted area, the oxygen concentration is decreasing, the temperature is increasing, etc.) It is also possible to set a warning in advance. In addition, the above process is performed by WPC
It is also possible to make settings so that the monitoring server 17 does so instead of 1-1. At this time, the WPC 1-1 supports the monitoring server 17.

The operation of the ninth embodiment of the site support system according to the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. In this example, various ships, aircraft, rockets and other manufacturing sites, inspection and maintenance sites,
An example of application of the present invention to on-site support for ensuring safety at a site where an operator performs various operations, such as an installation location, will be described. However, the present invention can be applied not only to the above-mentioned case but also to a place where safety is required for other work.

At various sites, site support measures for ensuring safety include various signs related to safety, displays such as signs, protective fences for preventing intrusion, warnings for notifying danger, and the like. However, it is not always appropriate and effective in a case where entry is prohibited or a dangerous area is suddenly generated at a certain point in time, or in a case where the work environment is apt to change.

Also, in the case of the WPC mounting worker 1, the HMD
You may be distracted by the display or touch panel, etc., overlooking the above display, wearing a non-explosion-proof WPC, entering the explosion-proof area while the power of the WPC is ON, and paying attention to the voice guidance Various cases are possible, such as the inability to hear the call.

In the present invention, WPC-specific functions are used to provide on-site support so that a WPC wearer can safely work. For example, at various sites, a warning is automatically displayed on the HMD and an alarm is sounded when a worker enters a restricted area or a dangerous area. When entering the explosion-proof area, the power is automatically turned off immediately. It has a gas sensor, detects the generation of toxic gas or lack of oxygen, automatically displays a warning on the HMD, and sounds an alarm. With such a function, the worker can safely perform the work (even if the work is performed alone). And it can contribute to improvement of work efficiency and cost reduction.

With reference to FIGS. 28, 29, and 31, a process for ensuring the safety of the work site will be described. First, at the stage of starting work at various sites, workers (here, worker P150, worker Q151, and site safety supervisor 1)
52) is preparing for the following. The WPC shown in FIGS. 1 to 3 is mounted, and is connected to the monitoring server 153 via the LAN 155 shown in FIG. 28 via the wireless unit 2-2 of the WPC. The monitoring server 153 is connected to the monitoring database 154 and is in a state where the information can be extracted at any time.

[0328] The worker P150 and the worker Q151 are working in the permission area 157. W for worker P
The PC 150-1 and the WPC 151-1 for the worker Q are provided with attached measuring devices (gas sensor, pressure sensor, thermometer,
The working environment is automatically measured by a measuring device that measures the working environment such as an anemometer, a vibrometer, an acoustic meter, and a radiation meter, and the working environment where the worker P150 and the worker Q151 are placed is confirmed ( S701). Allowed area 15 in advance
If it is known that there is no problem in the work environment 7, this step can be omitted.

Next, WPC 150-1 for worker P and WPC 151-1 for worker Q confirm the situation where worker P150 and worker Q151 are located (S702).
The information of the worker himself / herself is stored in advance by the worker P WPC 150-
1 and WPC 151-1 for worker Q. Further, if the position of the worker P150 and the worker Q151 is an outdoor work, the wearable G connected to the worker P WPC 150-1 or the worker Q WPC 151-1 may be used.
It can be grasped by PS. In addition, the confirmation of the physical condition of the worker can be omitted when the problem is not caused in the working environment and there is no problem in the health of the worker.

The location information is grasped by the WPCs, and is transmitted from the radio section 2-2 to the wireless LAN.
The monitoring server 153 is transmitted to the terminal A 159-1, and based on the position information, the monitoring server 153 transmits the worker P150 and the worker Q1.
The position of 51 can be known. When the work site is indoors or when GPS is not used, the worker P150
And the operator Q151 has the wireless LAN terminal A159.
-1, when transmitting and receiving work information,
From the information from the AN terminal A 159-1, the monitoring server 153 can know the positions of the worker P150 and the worker Q151. Based on that information,
C himself can grasp his position.

Next, based on the information in S701 and S702, the worker determines whether there is a safety problem (S703). When the worker P150 is in the permission area 157, there is no problem in both the environment and the situation. Therefore, the step jumps to S707.

However, if the worker P150 enters the restricted area 158 during the work, the position information by GPS or the worker P150
According to the information from the wireless LAN terminal B 159-2 that the work information has begun to be transmitted and received via the 159-2, the worker P WPC 150-1 and the monitoring server 153 cause the worker P150 to enter the restricted area 158. Detect that

The worker P WPC 150-1 is
It is determined that a safety problem has occurred due to the entry of the 150 into the off-limits area 158, and a corresponding measure is performed on the worker P150 (S704). That is, a warning by the screen display of the HMD 7 of the worker P WPC 150-1 and the sound of the headphones 9 is automatically issued. Thereby, the worker P150 can recognize that the user has entered the restricted area 158, and can take appropriate measures.

[0334] It is also possible to adopt a method in which a corresponding measure is executed according to an instruction from the monitoring server 153. That is, the monitoring server 153 refers to the information in the monitoring database 154 and confirms that the current position of the worker P150 is in the restricted area 158. Then, in accordance with the processing method when the user enters the restricted area in the monitoring database 154, a warning or the like is issued to the worker P via the LAN 155.
To the WPC 150-1 for use. WPC15 for worker P
0-1 automatically receives a warning message or the like in the wireless unit 2-2 by wireless communication, and automatically issues a warning message to the worker P WPC.
It is displayed on the HMD 7 of 150-1. At the same time, an audio warning is issued.

The monitoring server 153 is a site safety supervisor W
The operator P150 enters the PC 152-1 in the restricted area 15
8 is notified via the LAN 155. The site safety supervisor 152 similarly recognizes the intrusion of the worker P150. Then, using the WPC 152-1 for the on-site safety supervisor, the position information of each worker recognized by the monitoring server 153 is read, the positions of the worker P150 and other workers are confirmed, and appropriate measures (wireless communication Warning and subsequent confirmation).

A worker who satisfies a certain condition (worker P
In this case, the worker Q151), such as a worker or a person in charge of the work site, which is within a certain distance from 150, is also contacted from the monitoring server 153, and the workers can give mutual attention.

After the corresponding action, WPC 150-1 for worker P
Determines whether a safety problem has been avoided (S
705). The determination is made by the worker P150 in the off-limits area 15
If it is out of step 8, the corresponding action ends (S706).
If the worker P150 is not out of the no-go area 158, the process returns to S704, and a corresponding action is performed. In that case, it is possible to repeat the same response measures,
It is also possible to set to take additional countermeasures such as issuing a stronger warning.

After recovery of the restricted function, the operator P150
It is determined whether or not the work has been completed (S707). If it has been completed, the safety-related management process for the operation is completed. If not, the process returns to S701 and continues to monitor the safety of the worker.

Another process for ensuring the safety of the work site will be described with reference to FIGS. 28, 30, and 31. First,
At the stage of starting work at various sites, workers (here, workers P150, Q151, and site safety supervisor 152) are preparing for the following. 1 to 3
Is attached, and the monitoring server 15 is connected to the LAN 155 shown in FIG. 28 via the wireless unit 2-2 of the WPC.
3 to be connected. The monitoring server 153 is connected to the monitoring database 154 and is in a state where the information can be extracted at any time.

The worker P150 and the worker Q151 are working in the permission area 157. In each of the work areas (the permission area 157 and the off-limits area 158), the infrared information generation devices 160 (-1 to 2) are installed. Then, information on safety in the work area is constantly transmitted from the device. The contents include, for example, the place is a restricted area, an explosion-proof area, a closed place (possible lack of oxygen), a high-temperature area, a high-pressure area, an exposure environment, and the like. Sensors, pressure sensors, thermometers, anemometers, vibrometers,
Information measured by measuring instruments that measure the working environment, such as an acoustic meter and a radiation measuring instrument). Information related to safety, such as warning them, coping methods, and wearing protective equipment and urging them to carry a gas sensor. Accordingly, the worker P WPC 150-1 and the worker Q WPC 151-1 confirm the work environment where the worker P150 and the worker Q151 are placed (S701).

At the same time, WPC1 for worker P
50-1 and WPC 151-1 for worker Q are workers P1
The situation where 50 and the worker Q151 are placed is confirmed (S702). The information of the worker himself has been input to the worker P WPC 150-1 and the worker Q WPC 151-1 in advance. Further, the worker P150 and the worker Q151
Can be grasped from the information from the infrared information generator 160 (-1 to 2). In addition, the confirmation of the physical condition of the worker can be omitted when the problem is not caused in the working environment and there is no problem in the health of the worker.

Next, based on the information in S701 and S702, the worker judges whether there is a safety problem (S703). When the worker P150 is in the permission area 157, there is no problem in both the environment and the situation. Therefore, the step jumps to S707.

However, if the worker P150 enters the no-go area 158 during work, the worker P WPC 15
0-1 receives safety-related information (intruding into the restricted area) constantly generated from the infrared information generating device 160-2. Then, based on the content of the information, the worker P
The WPC 150-1 determines that a safety problem has occurred due to the entry of the worker P150 into the no-go area 158, and performs a corresponding action on the worker P150 (S
704). That is, the worker P WPC 150-1 is
A warning message is automatically displayed on the HMD 7. At the same time, a warning is given by voice. Thereby, the worker P150 can recognize that the user has entered the restricted area 158, and can take appropriate measures.

At the same time, the worker P WPC 15
0-1 automatically transmits the fact of intrusion into the restricted area 158 to the monitoring server 153 via the LAN 155 from the wireless unit 2-2 by wireless communication. Thereby, the monitoring server 1
53 detects that the worker P150 has entered the restricted area 158.

Then, the monitoring server 153 notifies the WPC 152-1 for the on-site safety supervisor that the worker P150 has entered the restricted area 158 via the LAN 155. The site safety supervisor 152 similarly recognizes the intrusion of the worker P150. And WPC15 for site safety supervisor
Using 2-1, the position information of each worker recognized by the monitoring server 153 is read, the positions of the worker P150 and other workers are confirmed, and appropriate measures (warning by wireless communication, subsequent confirmation) Can be.

After the corresponding action, WPC 150-1 for worker P
Determines whether a safety problem has been avoided (S
705). The determination is made by the worker P150 in the off-limits area 15
If it is out of step 8, the corresponding action ends (S706).
If the worker P150 is not out of the no-go area 158, the process returns to S704, and a corresponding action is performed. In that case, it is possible to repeat the same response measures,
It is also possible to set to take an additional countermeasure such as a stronger warning and a restriction on the function of the WPC.

[0347] Similarly, the on-site safety supervisor 152
Recognize 150 intrusions. And W for site safety supervisor
Using the PC 152-1, the position information of each worker recognized by the monitoring server 153 is read, the positions of the worker P150 and other workers are confirmed, and appropriate measures (warning by wireless communication, subsequent confirmation) Can be.

An operator (operator P) who satisfies a certain condition
In this case, the worker Q151), such as a worker or a person in charge of the work site, which is within a certain distance from 150, is also contacted from the monitoring server 153, and the workers can give mutual attention.

After recovery of the restricted function, the operator P150
It is determined whether or not the work has been completed (S707). If it has been completed, the safety-related management process for the operation is completed. If not, the process returns to S701 and continues to monitor the safety of the worker.

With the above-described process, the safety of the work performed by the WPC mounting worker can be surely improved. In addition, accidents can be prevented beforehand, and the work efficiency is improved, and there are tremendous effects such as improvement of work quality, reduction of workers, shortening of construction period, and cost reduction.

[0351]

According to the present invention, it is not necessary to input work and inspection records at the site and then re-input them later, and it is possible to greatly improve work efficiency.

Further, according to the present invention, it is possible to acquire information necessary for work when necessary regardless of the storage location of information, and to effectively use records of work and inspection.
