The storage unit 26 stores the work information, the position information of the work place, and the work target information (work target information) in association with each other. Further, the storage unit 26 stores design drawing data of the construction site.

As this kind of design drawing data, for example, there is data called BIM (Building Information Modeling). The BIM contains not only the data of the building itself but also the data of furniture, and the data of the construction process is also registered. That is, in the design drawing data stored in the storage unit 26, information on the construction location and the work content (for example, the name of the member to be fixed with the screw, the tightening force, etc.) is registered for each of the plurality of objects. By aligning the reference point of the building in the design drawing data with the reference point of the work site, the actual position on the work site can be obtained from the position on the drawing for each object.

Further, the smart terminal 2 has a function of communicating with the management device 7 via a public line network 6 such as the Internet. The management device 7 holds design drawing data of a work site where work is performed using the tool 1. The smart terminal 2 stores the design drawing data downloaded from the management device 7 via the public line network 6 in the storage unit 26. The smart terminal 2 may download all the design drawing data of the work site and store it in the storage unit 26, or download a part of the design drawing data (for example, the design drawing data of only the work area where the work is performed on the day). Then, it may be stored in the storage unit 26.

Next, the operation of this work management system will be described with reference to FIG. In the following, the screw tightening work when fixing the solar cell panel to the gantry will be described as an example.

When the operator operates the operation unit 24 of the smart terminal 2 to input the start of the work (S1 in FIG. 4), the signal processing unit 21 will perform the work to be performed based on the design drawing data read from the storage unit 26. Is displayed on the display unit 23 (S2 in FIG. 4). When the work to be performed is screw tightening work, the instruction information includes the place where the screw tightening work is performed, the product name of the work target (name of the member to be tightened with the screw, for example, the solar cell panel), the number of screws (bolts) to be tightened, and the tightening. There are force settings and so on. The signal processing unit 21 of the smart terminal 2 may transmit the data of the work content to be performed from the communication unit 22 to the wearable terminal 5 and display it on the display unit 54 of the wearable terminal 5. Further, the signal processing unit 21 of the smart terminal 2 transmits information on the set value of the tightening force from the communication unit 22 to the tool 1 (S3 in FIG. 4). In the tool 1, when the communication unit 15 receives the information on the set value of the tightening force from the smart terminal 2, the control unit 11 stores the information on the set value of the tightening force in the storage unit 16 (S4 in FIG. 4). In addition, the smart terminal 2 may send the set value of the tightening force in the next screw tightening work to the tool 1 each time the screw tightening work is performed by using the tool 1, or the work (a plurality of times). For example, the set value of the tightening force may be transmitted to the tool 1 in the order of performing the work (work performed on the day). In this case, the control unit 11 of the tool 1 stores the set values of the plurality of operations in the storage unit 16, and controls the tightening force of the tightening unit 13 based on the set values read out in order from the storage unit 16. do it.

When the worker confirms the instruction information displayed on the display unit 23 of the smart terminal 2 or the display unit 54 of the wearable terminal 5, he / she moves to the work place of the work to be performed and uses the barcode reader 4 to move the member to be worked. The bar code attached to is read (S5 in FIG. 4). The information read by the barcode reader 4 is output to the smart terminal 2. The work target information acquisition unit 213 acquires work target information for specifying the work target of the work to be performed based on the information input from the barcode reader 4 (S6 in FIG. 4).

When the work target information acquisition unit 213 acquires the work target information, the position information acquisition unit 212 outputs a positioning command requesting positioning data to the GPS receiver 3 connected to the smart terminal 2. When the GPS receiver 3 receives the positioning command from the smart terminal 2, it positions the current position and outputs the positioning data to the smart terminal 2 (S7 in FIG. 4). When the position information acquisition unit 212 receives the positioning data from the GPS receiver 3, the position information acquisition unit 212 acquires the position information indicating the current position (working place) based on the positioning data (S8 in FIG. 4). The GPS measurement error is about several meters, but once the operation of the quasi-zenith satellite that passes through the zenith of Japan is started, the measurement error will be about several centimeters, and the position information of the construction site will be measured more accurately. can do.

When the operator sets a screw on the member to be worked and operates the operation unit 12, the control unit 11 of the tool 1 rotates the tightening unit 13 to start the bolt tightening work (S9 in FIG. 4). .. The control unit 11 controls the rotation of the tightening unit 13 so that the tightening force measured by the measuring unit 14 matches the set value of the tightening force read from the storage unit 16. When the error between the tightening force measured by the measuring unit 14 and the set value falls within a predetermined allowable range (for example, ± 20% of the set value), the control unit 11 stops the operation of the tightening unit 13. The control unit 11 causes the communication unit 15 to transmit the tightening force data measured by the measurement unit 14 as work information to the smart terminal 2 (S10 in FIG. 4).

When the communication unit 22 of the smart terminal 2 receives the work information from the tool 1, the information management unit 214 has the work information, the position information acquired by the position information acquisition unit 212, and the work target acquired by the work target information acquisition unit 213. The information is associated with the information and stored in the storage unit 26 (S11 in FIG. 4). As a result, regarding the work performed by the worker using the tool 1, the work information, the position information, and the work target information are stored in the storage unit 26 in association with each other. You can manage whether you have done the work place and work contents). The information management unit 214 may store the time information in which the work is performed in the storage unit 26 in association with the work information, the position information, and the work target information for each work, and when each work is performed. You can control what was done.

Here, the determination unit 215 compares the work information, the position information, and the work target information stored in the storage unit 26 with the instruction content based on the design drawing data, and performs the work according to the instruction content to the work target. It may be determined whether or not it has been damaged (S12 in FIG. 4). The determination unit 215 reads the work instruction for the work target specified by the work target information from the design drawing data, and the work place indicated by the position information and the work content (for example, tightening force) indicated by the work information are as in the work instruction. Judge whether or not.

The work target specified in the work target information is installed at the location specified in the design drawing data, and the error between the actual tightening force and the work instruction is within a predetermined allowable range (for example, 10% of the set value). If so, the determination unit 215 determines that the work content is good and displays it on the display unit 23. On the other hand, if the work target specified by the work target information is installed in a place different from the work instruction, or if the error between the actual tightening force and the work instruction is not within the permissible range, the determination unit 215 works. It is determined that the content is defective, and the display unit 23 displays the content. The determination unit 215 may store the work information, the position information, the work target information of each work in the storage unit 26 in association with the result of determining the quality of the work content. Further, the determination unit 215 may transmit the determination result from the communication unit 22 to the wearable terminal 5, or may display the result of determining the quality of the work on the display unit 54 of the wearable terminal 5. The operator can notice that the content of the work is defective based on the determination result displayed on the display unit 23 of the smart terminal 2 or the display unit 54 of the wearable terminal 5. When the determination unit 215 determines that the work content is defective, the signal processing unit 21 may display a display instructing the work rework on the display unit 23 or the display unit 54 of the wearable terminal 5, improving the quality of the work. Can be planned. Further, when the determination unit 215 determines that the work content is defective, the signal processing unit 21 may display a display instructing the correct work method on the display unit 23 or the display unit 54 of the wearable terminal 5. It is possible to improve the skill level of the person. Further, since the storage unit 26 stores the result of determining the quality of the work content in association with the work information, the position information, and the work target information of each work, the work history and the work history are stored for each work. , The result of determining the quality of the work content can be saved in association with the result.

In the work management system of the present embodiment, when the control unit 11 of the tool 1 transmits the work information, the tool information stored in the storage unit 16 may be transmitted from the communication unit 15 to the smart terminal 2. When the communication unit 22 of the smart terminal 2 receives the tool information transmitted from the tool 1, the tool information acquisition unit 216 is a tool related to the specifications of the tool 1 used for the work based on the tool information received from the tool 1. Get information. In this case, the information management unit 214 can store the tool information in the storage unit 26 in association with the work information, the position information, and the work target information for each work. Information on the tool 1 used in each operation is also registered in the design drawing data stored in the storage unit 26. Therefore, the determination unit 215 collates the tool information of the tool 1 actually used for each work with the information of the tool 1 registered in the design drawing data, and as instructed by the design drawing data. It can be determined whether or not the work has been performed using the tool 1. If the tool information received from the tool 1 and the information of the tool 1 registered in the design drawing data do not match, the signal processing unit 21 displays the design drawing on the display unit 23 or the display unit 54 of the wearable terminal 5. It may be displayed that the tool 1 different from the instruction of the data is used. This can encourage the operator to use the tool 1 as instructed in the design drawing data.

By the way, a worker carrying the smart terminal 2 forgets to move the tool 1 or the tool 1 is stolen, and the distance between the smart terminal 2 and the tool 1 is between the communication unit 15 and the communication unit 22. When the communicable distance (threshold value) of the above is exceeded, the communication unit 22 cannot communicate with the communication unit 15 of the tool 1. The communication unit 22 of the smart terminal 2 and the communication unit 15 of the corresponding tool 1 are communicating periodically (for example, a cycle of several tens of seconds to several minutes), and the communication unit 22 cannot communicate with the communication unit 15. Then, the signal processing unit 21 determines that the corresponding tool 1 is farther than the communicable distance. Then, the signal processing unit 21 causes the display unit 23 to display the content notifying that the tool 1 is farther than the communicable distance (threshold value). The signal processing unit 21 of the smart terminal 2 notifies that when the communication unit 15 and the communication unit 22 of the corresponding tool 1 cannot communicate with each other, the corresponding tool 1 is farther from the smart terminal 2 than the threshold value.
