[0009] (Usage statistics system) Fig. 1 is a block diagram showing the configuration of a usage status collecting system 1 according to this embodiment. Fig. 2 is a schematic diagram of an image of a work area 2 according to this embodiment.

[0010] As shown in FIG. 1, the usage status collecting system 1 includes an imaging device 10, a first production facility 20, a second production facility 30, a work tool 40, and a usage status collecting device 50.

[0011] 1. Imaging device The imaging device 10 is installed in a factory. The imaging device 10 captures an image 2A of a work area 2. As shown in FIG. 2, the work area 2 includes a first work location 3 and a second work location 4. The imaging device 10 captures the image 2A of the work area 2 and generates image data representing the image 2A. The image data includes the date and time when the image 2A was captured. The imaging device 10 transmits the generated image data to the usage status aggregation device 50.

[0012] 2. Production Equipment The first production facility 20 is located at a first work location 3. The second production facility 30 is located at a second work location 4.

[0013] The first and second production facilities 20 and 30 are various types of facilities required to produce desired products. A worker W supports the first and second production facilities 20 and 30 by performing predetermined tasks using a work tool 40.

[0014] Each of the first and second production facilities 20, 30 transmits operation status data indicating whether the facilities are in operation or stopped to the usage status collecting device 50. As shown in Fig. 1, the operation status data includes the operation start date and time and the operation stop date and time of the production facilities.

[0015] 3.Work tools The work tool 40 is used by the worker W for a predetermined task. FIG. 3 is a schematic diagram showing the work tool 40 according to this embodiment. The work tool 40 according to this embodiment is a vernier caliper. However, the type of the work tool 40 is not limited as long as it is a tool that the worker W can hold in his / her hand.

[0016] An acceleration beacon 41 is attached to the work tool 40. As shown in FIG.

[0017] The ID storage unit 42 pre-stores an ID that is uniquely set for the work tool 40. The ID of the work tool 40 can be set arbitrarily.

[0018] The accelerometer 43 measures the acceleration of the work tool 40. The accelerometer 43 generates acceleration data that indicates the progress of the acceleration of the work tool 40. The acceleration data includes the date and time when the acceleration was measured. The acceleration data according to this embodiment is an example of "use data" that indicates whether the work tool 40 is being used or not.

[0019] The wireless transmitter 44 wirelessly transmits the ID of the tool 40 and the acceleration data to the usage status collecting device 50 in association with each other.

[0020] 4. Usage status aggregation device 50 The usage status collecting device 50 is installed inside a factory. The usage status collecting device 50 may also be installed outside a factory, in which case it may receive information from the imaging device 10, the first production equipment 20, the second production equipment 30, and the acceleration beacon 41 via a network.

[0021] As shown in FIG. 1, the usage status collecting device 50 includes an acceleration data processing unit 51, an image data processing unit 52, a driving data processing unit 53, and a collecting unit .

[0022] The acceleration data processing unit 51 receives the ID and acceleration data of the work tool 40 from the wireless transmitter 44. The acceleration data processing unit 51 references the ID of the work tool 40 and recognizes that the acceleration data is data related to the work tool 40. The acceleration data processing unit 51 detects whether the work tool 40 is being used or not based on the acceleration data. The acceleration data processing unit 51 according to this embodiment is an example of a "use / non-use data processing unit" that detects whether the work tool 40 is being used or not.

[0023] FIG. 4 is an example of a graph showing the progression of acceleration when the worker W uses the work tool 40 while holding it in his hand. The acceleration data processing unit 51 detects that the work tool 40 is "in use" when the acceleration is greater than an upper limit value TH1. The acceleration data processing unit 51 also detects that the work tool 40 is "in use" when the acceleration is less than a lower limit value TH2. The acceleration data processing unit 51 detects that the work tool 40 is "not in use" when the acceleration is equal to or less than the upper limit value TH1 and equal to or greater than the lower limit value TH2.

[0024] The acceleration data processing unit 51 outputs the detection result to the counting unit 54. Specifically, the acceleration data processing unit 51 outputs to the counting unit 54 whether or not the work tool 40 was used, in association with the date and time.

[0025] The image data processing unit 52 receives image data from the imaging device 10. Based on the image data, the image data processing unit 52 detects the position of the worker W on the image 2A of the work area 2. In the example shown in FIG. 2, the worker W is detected in the first work location 3.

[0026] The image data processing unit 52 can detect the position of the worker W on the image 2A by a determination process of the artificial intelligence using the trained model. The trained model is created in advance by a learning process of the artificial intelligence using the learning image data of the image 2A.

[0027] The image data processing unit 52 outputs the detection result to the counting unit 54. Specifically, the image data processing unit 52 outputs the position of the worker W and the date and time to the counting unit 54 in association with each other.

[0028] The operation data processing unit 53 receives operation status data from each of the first and second production facilities 20, 30. Based on the operation status data, the operation data processing unit 53 detects the operation status of each of the first and second production facilities 20, 30. With reference to the operation status data, the operation data processing unit 53 detects the period from the operation start date and time to the subsequent operation stop date and time as "in operation," and detects the period from the operation stop date and time to the subsequent operation start date and time as "stopped."

[0029] The operation data processing unit 53 outputs the detection result to the aggregation unit 54. Specifically, the operation data processing unit 53 associates the operation states of the first and second production facilities 20, 30 with the date and time, and outputs them to the aggregation unit 54.

[0030] The counting unit 54 counts the usage status of the work tool 40 based on the detection results of the acceleration data processing unit 51. The usage status of the work tool 40 can be evaluated based on the usage time of the work tool 40. The counting unit 54 counts the usage time of the work tool 40 based on the date and time associated with the "used" status of the work tool 40. Alternatively, the usage status of the work tool 40 can be evaluated based on the number of times the work tool 40 is used (frequency of use). The counting unit 54 counts the number of times the work tool 40 is used based on the number of times the work tool 40 is "used."

[0031] Based on the detection results of the image data processing unit 52, the counting unit 54 counts the usage status of the work tool 40 for each of the first and second work locations 3 and 4. The counting unit 54 compares the date and time associated with the location of the worker W with the date and time associated with the "used" status of the work tool 40, and can count the usage time and number of times the work tool 40 has been used for each of the first and second work locations 3 and 4.

[0032] The counting unit 54 counts the usage status of the work tool 40, dividing it into when it is in operation and when it is stopped, based on the detection result of the operation data processing unit 53. The counting unit 54 compares the date and time associated with the operation state of each of the first and second production equipment 20, 30 with the date and time associated with the "used" status of the work tool 40, and can count the usage time and number of times it is used, dividing it into when it is in operation and when it is stopped.

[0033] Fig. 5 is a graph showing an example of the results of tallying the usage time of the work tool 40. In Fig. 5, the usage time of the work tool 40 is tallied for each of the first and second work locations 3 and 4, separately for when the first and second production equipment 20 and 30 are in operation and when they are stopped.

[0034] Fig. 6 is a graph showing an example of the results of counting the number of times the work tool 40 is used. In Fig. 6, the number of times the work tool 40 is used is counted for each of the first and second work locations 3 and 4, separately for when the first and second production facilities 20 and 30 are in operation and when they are stopped.

[0035] As described above, the usage status collection system 1 according to this embodiment can accurately detect whether the tool 40 is being used based on the acceleration data of the tool 40, and therefore can accurately collect usage status of the tool. As a result, the efficiency of use of the tool 40 can be improved.

[0036] Furthermore, since the usage status of the work tool 40 can be grasped for each location where the work tool 40 is used, the usage efficiency of the work tool 40 can be further improved.

[0037] Furthermore, since the usage status of the work tool 40 can be grasped separately for when the first and second production facilities 20, 30 are in operation and when they are stopped, the usage efficiency of the work tool 40 can be further improved.

[0038] (Modification of the embodiment)

[0039] [Variation 1] In the above embodiment, the usage status collection system 1 includes the accelerometer 43 and the acceleration data processing unit 51, but is not limited to this.

[0040] For example, the usage status collection system 1 may include a proximity sensor, instead of the accelerometer 43, that detects whether the tool 40 is in proximity to a predetermined position (e.g., a storage location for the tool 40). The proximity sensor generates proximity status data that indicates a transition in whether the tool 40 is in proximity (or the degree of proximity). The proximity status data includes the date and time when the proximity (or the degree of proximity) was detected. In this case, the usage status collection system 1 includes a proximity status data processing unit instead of the acceleration data processing unit 51. The proximity status data processing unit detects no proximity (or the degree of proximity is equal to or less than a threshold) as "use" of the tool 40. The proximity status data is an example of "use status data" according to the present disclosure, and the proximity status data processing unit is an example of "use status data processing unit" according to the present disclosure.

[0041] Furthermore, the usage status collection system 1 may be provided with a contact sensor, instead of the accelerometer 43, that detects when the worker W holds the work tool 40 in his / her hand. The contact sensor is attached to the grip portion of the work tool 40. The contact sensor generates contact status data that indicates a transition between the presence or absence of contact. The contact status data includes the date and time when the presence or absence of contact was detected. In this case, the usage status collection system 1 is provided with a contact status data processing unit instead of the acceleration data processing unit 51. The contact status data processing unit detects the presence of contact as "use" of the work tool 40. The contact status data is an example of "use status data" according to the present disclosure, and the contact status data processing unit is an example of "use status data processing unit" according to the present disclosure.

[0042] [Variation 2] In the above embodiment, the usage status collecting device 50 includes the image data processing unit 52. However, if it is not necessary to collect the usage status of the work tool 40 for each work location, the usage status collecting device 50 does not need to include the image data processing unit 52. In this case, the usage status collecting system 1 does not need to include the imaging device 10 and the image data processing unit 52.

[0043] [Variation 3] In the above embodiment, the usage status collecting device 50 includes the operation data processing unit 53. However, if it is not necessary to collect information on the usage status of the implement 40 by dividing it into "in operation" and "off-operation," the usage status collecting device 50 does not need to include the operation data processing unit 53. In this case, the usage status collecting system 1 does not need to include the operation data processing unit 53.

[0044] [Variation 4] In the above embodiment, the work area 2 includes the first work location 3 and the second work location 4, but the number of work locations included in the work area 2 may be one or more.

[0045] [Variation 5] In the above embodiment, a case where the worker W uses the work tool 40 has been described, but the number of work tools 40 is not particularly limited. The usage status collecting device 50 can collect the usage status of each work tool 40 by using the ID of each work tool 40. [Explanation of symbols]
