Further, the smart terminal 2 has a function of communicating with the management device 7 via the public line network 6 such as the Internet. The management device 7 holds design drawing data of a work site where the tool 1 is used for work. 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. Below, it demonstrates taking the case of the screw fastening operation | work at the time of fixing a solar cell panel to a mount frame.

When the operator operates the operation unit 24 of the smart terminal 2 and inputs the start of work (S1 in FIG. 4), the signal processing unit 21 performs work to be performed from now on based on the design drawing data read from the storage unit 26. Is displayed on the display unit 23 (S2 in FIG. 4). If the work to be performed is a screw tightening work, the instruction information includes the location where the screw tightening work is performed, the name of the work target (name of the member to be tightened with a screw, such as a solar panel), the number of screws (bolts) to be tightened, and the tightening There is a setting value of force. Note that the signal processing unit 21 of the smart terminal 2 may transmit data on work contents to be performed from the communication unit 22 to the wearable terminal 5 and display the data 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 information on the setting value of the tightening force from the smart terminal 2, the control unit 11 stores information on the setting value of the tightening force in the storage unit 16 (S4 in FIG. 4). The smart terminal 2 may transmit the set value of the tightening force in the next screw tightening operation to the tool 1 every time the screw tightening operation is performed once using the tool 1, or a plurality of operations ( For example, the setting value of the tightening force may be transmitted to the tool 1 in the order in which the operations are performed on the day). In this case, the control unit 11 of the tool 1 stores the set values of a plurality of operations in the storage unit 16 and controls the tightening force of the tightening unit 13 based on the set values read 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, the worker moves to the work place where the work is to be performed and uses the barcode reader 4 to select the member to be worked on. Is read (S5 in FIG. 4). Information read by the barcode reader 4 is output to the smart terminal 2. Based on the information input from the barcode reader 4, the work target information acquisition unit 213 acquires work target information for specifying the work target of the work to be performed (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 for requesting positioning data to the GPS receiver 3 connected to the smart terminal 2. When receiving the positioning command from the smart terminal 2, the GPS receiver 3 measures the current position and outputs the positioning data to the smart terminal 2 (S7 in FIG. 4). When receiving the positioning data from the GPS receiver 3, the position information acquisition unit 212 acquires position information indicating the current position (working place) based on the positioning data (S8 in FIG. 4). Although the GPS measurement error is about a few meters, the measurement error will be about a few centimeters when the operation of the quasi-zenith satellite that passes almost the zenith in Japan is started, and the location information of the construction site is measured more accurately. can do.

When the operator sets the screw on the work target member and operates the operation unit 12, the control unit 11 of the tool 1 rotates the tightening unit 13 to start the bolt tightening operation (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 measurement 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 data of the tightening force measured by the measurement unit 14 to be transmitted as work information from the communication unit 15 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 performs 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 and stored in the storage unit 26 (S11 in FIG. 4). Thereby, since the work information, the position information, and the work target information are associated with each other and stored in the storage unit 26 for the work performed by the operator using the tool 1, any work ( Work place and work content) The information management unit 214 may store the time information when 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. You can manage what happened.

Here, the determination unit 215 compares the work information, position information, and 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 for the work target. It may be determined whether or not it has been broken (S12 in FIG. 4). The determination unit 215 reads a work instruction for the work object specified by the work object information from the design drawing data, and the work location indicated by the position information and the work content (eg, tightening force) indicated by the work information are in accordance with the work instruction. It is determined whether or not.

The work target specified by the work target information is constructed at the location indicated by 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). Then, the determination unit 215 determines that the work content is good and causes the display unit 23 to display it. On the other hand, if the work target specified by the work target information is installed at a location different from the work instruction or the error between the actual tightening force and the work instruction is not within the allowable range, the determination unit 215 performs the work. It is determined that the content is defective and is displayed on the display unit 23. The determination unit 215 may store the work information, position information, and work target information of each work in association with the result of determining the quality of the work content in the storage unit 26. The determination unit 215 may cause the communication unit 22 to transmit a determination result to the wearable terminal 5, and may display a result of determining whether the work is good or bad on the display unit 54 of the wearable terminal 5. 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, the worker can notice that the content of the work is defective. When the determination unit 215 determines that the work content is defective, the signal processing unit 21 may display a display for instructing reworking on the display unit 23 or the display unit 54 of the wearable terminal 5 to improve work quality. Can be achieved. In addition, when the determination unit 215 determines that the work content is defective, the signal processing unit 21 may display a display for instructing a correct work method on the display unit 23 or the display unit 54 of the wearable terminal 5. The skill level of the person can be improved. In addition, since the storage unit 26 stores the result of determining the quality of the work contents in association with the work information, the position information, and the work target information of each work, the work history and the work history for each work are stored. The result of determining the quality of the work contents can be stored in association with each other.

In the work management system of the present embodiment, the control unit 11 of the tool 1 may cause the tool information stored in the storage unit 16 to be transmitted from the communication unit 15 to the smart terminal 2 when transmitting the work information. 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 uses the tool information received from the tool 1 as a tool related to the specification of the tool 1 used for the work. 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. In the design drawing data stored in the storage unit 26, information on the tool 1 used in each work is also registered. Accordingly, 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 in the design drawing data. It can be determined whether or not work has been performed using the tool 1. In addition, when 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. You may display that the tool 1 different from the data instruction | indication was used. As a result, the operator can be prompted to use the tool 1 as instructed in the design drawing data.

By the way, the worker carrying the smart terminal 2 forgets the tool 1 and moves 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. If the communicable distance (threshold value) is exceeded, the communication unit 22 becomes unable to 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 communicate regularly (for example, a period 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. And the signal processing part 21 displays the content which alert | reports that the tool 1 left | separated far from the communicable distance (threshold value) on the display part 23. FIG. In addition, when the communication unit 15 and the communication unit 22 of the corresponding tool 1 become unable to communicate with each other, the signal processing unit 21 of the smart terminal 2 notifies that the corresponding tool 1 is separated from the smart terminal 2 farther than the threshold value. The content to be transmitted may be transmitted from the communication unit 22 to the wearable terminal 5. When the communication unit 52 receives the notification content transmitted from the smart terminal 2, the control unit 51 of the wearable terminal 5 displays the notification content on the display unit 54. Therefore, the operator can confirm that the distance to the tool 1 has exceeded the threshold from the notification content displayed on the display unit 23 of the smart terminal 2 or the display unit 54 of the wearable terminal 5, and misplacement or theft of the tool 1 Can be noticed to the operator.

Further, when the work information acquisition unit 211 of the smart terminal 2 acquires the work information from the tool 1, the video information acquisition unit 217 may cause the communication unit 22 to transmit an imaging command for capturing a video to the wearable terminal 5. When the communication unit 52 receives the imaging command transmitted from the smart terminal 2, the control unit 51 of the wearable terminal 5 causes the imaging unit 53 to capture a video (a still image or a moving image), and an image captured by the imaging unit 53. Data is transmitted from the communication unit 52 to the smart terminal 2. When the communication unit 22 receives the image data transmitted from the wearable terminal 5, the signal processing unit 21 of the smart terminal 2 associates the image data with work information, position information, and work target information about the current work. The data is stored in the storage unit 26. As a result, work information, position information, work target information for each work, and image data of the work site are stored in the storage unit 26 in association with each other. The image shown can also be saved together. Since the storage unit 26 stores an image showing the status of the site where the work is performed for each work, the actual work environment can be grasped from this image. It can also be used to provide guidance to workers who are unfamiliar with work and to improve work methods. Also, it is common to mark a screw after a screw tightening operation at a construction site or the like, but it is useful for construction management by taking an image after marking and storing it in the storage unit 26.

The biometric information thus transmitted is transmitted from the communication unit 52 to the smart terminal 2. When the communication unit 22 receives the biological information transmitted from the wearable terminal 5, the signal processing unit 21 of the smart terminal 2 associates the biological information with work information, position information, and work target information regarding the current work. The data is stored in the storage unit 26. As a result, the work information, position information, and work target information of each work and the biological information of the worker who performed the work are stored in the storage unit 26 in association with each other. Can also be stored together.

Therefore, the biological information of the worker who performed each work can be grasped from the biological information stored in the storage unit 26, which can be used for the health management of the worker. In addition, by monitoring the worker's biological information, it is possible to perform the work while ensuring the safety of the worker, for example, prohibiting a high blood pressure worker from working at a high place or causing heat stroke in a high temperature environment. You can give a break when you are about to develop. Therefore, even in work in a harsh environment, the worker can perform work while paying attention to the health of the worker, and the safety of the worker can be ensured. Note that the information management unit 214 may store the above-described tool information, video information, and biological information in the storage unit 26 in association with the work information, position information, and work target information of each work.
