FIG. 1 shows a work record management system 100 according to an embodiment of the present technology.

The work record management system 100 includes a client 110 including a processor and a memory, and a server 120 including a processor and a memory, which are directly or via a network such as the Internet, a LAN (Local Area Network), or a WAN (Wide Area Network). , Communicably connected. In the present application, “memory” refers to semiconductor storage devices such as random access memory (RAM) and read only memory (ROM) as well as auxiliary storage devices such as hard disk drive (HDD) and solid state drive (SSD). Including.

The work record management system 100 further includes a robot 130, a device controller 140, a sensor 150, and an integrated interface non-compliant device 160, which are communicably connected to the server 120 via a network or directly. In the present application, the robot 130, the device controller 140, the sensor 150, and the integrated interface non-compliant device 160 may be collectively referred to as an IoT device.

The client 110 stores application software 112 and database middleware 114 in memory, which can be run on a processor. The application software 112 is a program having a function of issuing a request to an IoT device or processing an event from the IoT device. For example, a production management system such as Hybrid Denno (trademark), GRANDIT (trademark), etc. General application software that can connect to databases such as ERP (Enterprise Resource Planning) system, other business system software, MS Excel, MS Access, BI (Business Intelligence) tools, ETL (Extract / Transform / Load) tools, etc. , And may be developed using package software. The application software 112 may be connected to the database using database connection means such as ODBC (Open Database Connectivity), JDBC (JavaTM Database Connectivity), OLE DB (Object Linking and Embedding DataBase).

The database middleware 114 converts the request from the application software 112 into a request for the database 122 and / or the IoT gateway service 124, and also responds from the database 122 and / or the IoT gateway service 124 to the application software 112. It has a function to convert. The database middleware 114 may be, for example, general-purpose database management software such as Oracle (trademark), SQL Server, MySQL, DB2, and the like.

The server 120 stores a database 122, an IoT gateway service 124, an integrated device interface connection add-in 126, a connection by device add-in 128, and an integrated device interface 129 in a memory, which can be executed on a processor.

The database 122 stores the request from the application software 112 and / or the response and event data from the IoT gateway service 124 in the memory together with the database middleware 114. In the present specification, the database middleware 114 and the database 122 may be collectively referred to as a database server.

Send to The device connection add-in 128 converts the instruction from the IoT gateway service 124 into an instruction corresponding to the integrated device interface non-compliant device 160 and sends it. The device-specific connection add-in 128 is prepared and executed according to the type of device.

FIG. 2 shows an exemplary sensor layout 200 of the work record management system according to an embodiment of the present technology.

The sensor arrangement example 200 includes a work bench X210, a work bench Y220, a work bench Z230, a worker A212, a worker B214, a worker C222, a worker D224, a sensor s260, a sensor t270, and a sensor u280.

A workbench is a place for performing a specific process, and a process is assigned to each workbench. The workbench X210, the workbench Y220, and the workbench Z230 may be places where different processes are performed, or may be places where the same work is performed.

Workers perform the work of the specific process assigned at the workbench. The worker A 212 and the worker B 214 perform the work of the assigned process on the work bench X 210.

Similarly, the worker C222 and the worker D224 carry out the work of the assigned process at the workbench Y220.

There is no process assigned to the work platform Z230, and there are no workers.

Each worker has a radio wave beacon and transmits a tag ID associated with the worker. For example, Ubisense's Series 9000 compact tag is used as the radio wave beacon. The radio wave beacon can measure the accurate three-dimensional position information of the tag with an accuracy of about 15 cm by combination with a sensor described later. The ultra-wide band, low pulse signal of 8.5 to 9.5 GHz makes it possible to always track thousands of objects at precise timings without interfering with other wireless systems in the factory. Furthermore, the radio wave beacon may have a vibration sensor, and when it is detected that there is no movement for a certain period of time, it may be determined as an abnormal value such as a misplacement of the radio wave beacon. Furthermore, it is possible to enable two-way communication with a sensor to be described later, so as to be able to detect lack of strength of the transmitted radio wave due to lack of remaining battery power or the like.

The radio wave beacon may be attached to a work clothes worn by the worker or may be attached to an ID card worn by the worker.

As used herein, “worker” may refer to a worker and / or a radio beacon attached to the worker.

A sensor s260, a sensor t270, and a sensor u280 are antennas for receiving the tag ID transmitted from the radio wave beacon, and have a function of measuring position information based on the incident angle of the signal received by each sensor and the arrival time difference. For example, Ubisense's Series 9000 IP sensor is used as the sensor. Two or more sensors are used for two-dimensional positioning, and three or more sensors are used for three-dimensional positioning. Positioning can be performed 40 times / sec by combining the radio beacon and sensor, and the position of 40 workers may be calculated every 1 second, and the position of 200 workers every 5 seconds It may be calculated to The sensor may measure the position information by the intensity difference of the signal received from the beacon.

The sensor s 260, the sensor t 270 and the sensor u 280 transmit positioning data including tag ID and position information to the server directly or via the network.

On the other hand, in the server, work range X218 including a plane or space near work bench X210, work range Y228 including a plane or space near work bench Y220, and work range Z238 including a plane or space near work bench Z230 Defined in the database of The server determines that the worker having the tag ID is performing the task assigned to the workbench X210 when the position information of the tag ID is included in the work range X218, and the workbench Y220 when included in the work range Y228. It is determined that the work assigned to the work table Z230 is being performed when it is included in the work range Z238. The work range may be defined as two-dimensional plane coordinates, or may be defined as three-dimensional space coordinates.

In FIG. 2, position information of tag IDs of the worker A 212 and the worker B 214 is included in the work range X 218, respectively. Therefore, the server determines that worker A 212 and worker B 214 are performing the work of the process assigned to workbench X 210.

Similarly, position information of tag IDs of the worker C222 and the worker D224 is included in the work range Y228. Therefore, the server determines that worker C 222 and worker D 224 are performing the work of the process assigned to workbench Y 220.

FIG. 3 shows another sensor arrangement example 300 of the work record management system according to the embodiment of the present technology.

Similar to the sensor arrangement example 200 of FIG. 2, the sensor arrangement example 300 includes the work bench X310, the work bench Y320, the work bench Z330, the worker A312, the worker B332, the worker C322, the worker D334, the sensor s360, and the sensor t370. , Sensor u380, work range X318, work range Y328, and work range Z338.

Unlike the sensor arrangement example 200 of FIG. 2, positional information of tag IDs of the worker B332 and the worker D334 is included in the work range Z338. Therefore, it is determined that worker B332 and worker D334 are performing the work of the process assigned to workbench Z330.

FIG. 4 shows a flowchart of a work record management method according to an embodiment of the present technology.

The work record management method 400 starts in step 410, and in step 420, the sensor receives the beacon from the tag, obtains the tag ID and the position information, and transmits it to the server.

Next, at step 430, the time, worker and work process are calculated and recorded from the tag ID and position information received by the server and the timer built in the server. In addition, you may use the time of the timer which a sensor has time.

Here, the tag ID may be associated in advance with each worker. Further, in the work process, the work range and the work process may be associated in advance. Furthermore, the association between the work range and the work process may be changed according to the time zone.

An example of the association between the work range and the work process is shown in Table 1. When the position information of the tag ID is included in the work range X, if the time is 8:00 to 12:00 or 13:00 to 17:00, it is determined that the work is performed in the manufacturing process, and the time is 12: If it is 00-13: 00, it is judged that the work is not performed.

When the position information of the tag ID is included in the work range Y, it is determined that the work is performed in the packaging process if the time is 8:00 to 12:00 or 13:00 to 17:00, and the time is 12: If it is 00-13: 00, it is judged that the work is not performed.

When the position information of the tag ID is included in the work range Z, if the time is 13:00 to 17:00, it is determined that the product shipment is performed, and if the time is 8:00 to 13:00 It is judged that the work is not done.

Table 1 is stored on the server as a database table and may be changed as needed.

When the processing of step 430 is completed for all tag IDs set in advance or all tag IDs detected by the sensor, it is determined at step 440 whether a predetermined time has elapsed or a predetermined time has been reached.

The predetermined time may be set arbitrarily, and may be, for example, 10 minutes, 30 minutes, 1 hour, half a day or 1 day. The predetermined time may be set arbitrarily, and may be 10 o'clock, 12 o'clock or 17 o'clock.

If it is determined in step 440 that the predetermined time has not elapsed and the predetermined time has not been reached, the process returns to step 420 and repeats the processing of steps 420 to 440.

In the database, repeated recorded data is accumulated as shown in Table 2.

Table 2 shows an example in which data is recorded at one minute intervals. Worker A was recorded as having worked in the manufacturing process between 8: 00-12: 00 and 13: 00-17: 00. It is recorded that worker B worked in the manufacturing process between 8:00 and 12:00 and worked on product shipment between 13:00 and 17:00. Worker C is recorded as having worked in the packaging process between 8:00 and 12:00 and between 13:00 and 17:00. It is recorded that worker D worked in the packaging process between 8:00 and 12:00 and worked on product shipment between 13:00 and 17:00.

If it is determined in step 440 that the predetermined time has elapsed or the predetermined time has been reached, the process proceeds to step 450, and the times, workers and work processes recorded so far are collected and stored.

The work manager may grasp the work status by viewing the tabulated report, and may issue a new work instruction or change the arrangement of workers as needed.

Next, in step 460, it is determined whether the end time has been reached.

If the end time has not been reached, the process returns to step 420 and repeats the processing of steps 420 to 460.

When the end time is reached, for example, when the work of one day is finished, the work record management method 400 ends at step 470.

The report summarized and stored in step 450 may be used as a daily work report immediately before the end of step 470.

Table 3 shows an example of the daily work report created in this manner.

In Table 3, worker A visits the office at 8:00, performs work of the manufacturing process at 8: 00-12: 00, takes a break at 12: 00-13: 00, 13: 00-17: 00. The work process of the manufacturing process is carried out, and a work daily report is announced at 17:00 stating that he left the company. The daily work report further indicates that the working hours of worker A on that day are eight hours, of which eight hours are spent on the manufacturing process.

Similarly, worker B visits the office at 8:00 and works at the manufacturing process from 8:00 to 12:00, takes a break from 12:00 to 13:00, and from 13:00 to 17:00. Work on product shipment is done, and at 17:00, a work daily report is created to the effect that you have left the company. The daily work report further indicates that the working hours of worker A on that day are 8 hours, of which 4 hours are spent on manufacturing process tasks, and 4 hours are spent on product shipping tasks.

Similarly, worker C visits the office at 8:00 and works at the packaging process at 8: 00-12: 00, taking a break at 12: 00-13: 00, and at 13: 00-17: 00. Work on the packaging process is carried out, and at 17:00, a daily work report to the effect of leaving the company is prepared. The daily work report further indicates that the working time of worker A on that day is 8 hours, of which 8 hours are spent on the packaging process.

Similarly, worker D visits the office at 8:00 and works at the packaging process at 8: 00-12: 00, takes a break at 12: 00-13: 00, and at 13: 00-17: 00. Work on product shipment is done, and at 17:00, a work daily report is created to the effect that you have left the company. The daily work report further indicates that the working hours of worker A on that day are 8 hours, of which 4 hours are spent on the packaging process and 4 hours are spent on the product shipping.

[Personnel cost and labor cost management]
The work record management system of the present technology can be used to manage labor costs such as labor costs of work processes. In the present specification, “labor cost” includes “labor cost” but is not limited thereto.

Table 4 shows the correspondence table between workers and unit price per hour (yen).

As shown in Table 4, the unit price of worker A is 1500 yen per hour, the unit price of worker B is 1400 yen per hour, the unit price of worker C is 1200 yen per hour, and the unit price of worker D is 1000 yen per hour. It is. Table 4 is stored on the server as a database table and may be changed as needed.

From the data of Table 3 and the unit price data of Table 4, data of labor costs for each process shown in Tables 5, 6 and 7 can be obtained from data of quantity obtained from the IoT device.

Table 5 shows the hourly labor cost in the manufacturing process and the labor cost per product

In Table 5, for example, at 8: 00-9: 00, Worker A and Worker B are working on the manufacturing process (see Table 3), and the hourly unit price of Worker A and Worker B is 1,500 yen each. Since the cost is 1,400 yen (see Table 4), the labor cost per hour of the manufacturing process is 2,900 yen. On the other hand, the data of the quantity acquired from the IoT device is 100 pieces, and the labor cost of the manufacturing process per product in this time zone is 29 yen. After that, the labor cost of the manufacturing process per product also fluctuates with the fluctuation of the production quantity.

From 13:00 to 14:00, only the worker A is working on the manufacturing process (see Table 3), and the unit price of the worker A is 1,500 yen (see Table 4). Labor costs will be 1,500 yen. On the other hand, the data of the quantity acquired from the IoT device is 50 pieces, and the labor cost of the manufacturing process per product in this time zone is 30 yen. After that, the labor cost of the manufacturing process per product also fluctuates with the fluctuation of the production quantity.

When the data is collected at the end of the day's work, the total labor cost of the manufacturing process is 17,600 yen, the manufacturing quantity is 600, and the labor cost of the manufacturing process per product is 29 yen.

Similarly, with regard to the packaging process and product shipment, as shown in Table 6 and Table 7, respectively, the labor cost and the labor cost per product can be stored as a total for each time zone or one day. The work manager may grasp labor costs associated with production by viewing the tabulated reports, and may issue a new work instruction or change the arrangement of workers as necessary.

The present technology makes it possible, for example, to obtain more accurate, detailed and easy labor costs such as work performances performed by workers and labor costs associated therewith.
