Description

  The present invention relates to a system for automatically recording a worker's action, which obtains the work record of the worker and data that can be used by a computer by a method that minimizes the burden of the input operation of the worker.

Japanese Patent Laid-Open No. 2003-84669 (Invention Name: Price Tag with Built-in IC and Price Tag Mounting Device) The present invention is characterized in that product information is included in the IC and the product information can be rewritten. The price tag in which the IC is built is described. In addition, it also describes an IC price tag in which store information is also included in the IC. In addition, an IC price tag having an adhesive on the back surface is also described. A price tag that can be separated into a price tag display part and an IC built-in part is also described. Further, an IC price tag having a structure in which a price tag display part and an IC built-in part are bonded with an adhesive is also described. As described above, IC price tags or price tags containing electronic tags (also referred to as IC tags or small wireless automatic recognition IC chips) are also described. On the other hand, many inventions using an electronic tag (also referred to as an IC tag) have been proposed as an alternative to a conventional tag with a barcode. However, the object of these inventions is mainly for merchandise management.

The present invention is a system for automatically recording the behavior of the worker, and the management in the conventional electronic tag and barcode formed mainly on the product is formed mainly on the handling of the article. It was unsuitable. That is, it is common practice to attach an electronic tag to a moving object (mainly a product) and read the electronic tag provided on the moving object with a fixed reading device. This is mainly because a lightweight electronic tag is provided on the moving side.
However, when an electronic tag is provided on the moving side,
[1] When a reading device is provided on a trajectory on which a moving object moves or on a trajectory that may move, the larger the number of installations, the higher the cost of the entire system. That is, when it is desired to install more reading points, the installation cost increases. In addition, when information obtained from the increasing reading points is integrated and data management is performed, the system for collecting the data increases by the number of reading points, so that the cost for integrating the data also increases.
[2] Comparing the electronic tag and the reader device, the size of the reader device is extremely large. Therefore, if many such large leader devices are installed around the work place, the effective use of the work place deteriorates. Moreover, since the size of the reader device is limited, there is a problem that the target to be detected cannot be set in detail.
[3] On the other hand, in the case of an existing bar code system, the worker's hand is constrained, the reading accuracy depends on the working environment, and the operator's skill is required for the reading accuracy. However, it was not easy to read a bar code in one hand of business, and it was insufficient in actual use.
An object of the present invention is to obtain a system in which a worker's intention and behavior can be transmitted by moving a body such as a limb between one hand of the work and almost without inputting consciousness.

An embodiment of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a perspective view depicting a work place. Also shown in FIG. 1 are a plurality of embodiments for implementing the system of the present invention.
That is, reference numeral 1 denotes a worker who works at the work place. A is a wall part which partitions a work place. B is a floor sheet laid in the passage of the entrance A1 of the wall A. C is a workbench, and C1 is a workbench sheet laid on the entire workbench. D is a belt conveyor and D1 is a belt. E is a guide plate, and E1 is a guide character string drawn on the guide plate. F is a work tool, G is a cloth material for sewing, and a number such as G1, G2, G3,... Can be set as necessary for each material of the cloth.

  FIG. 2 shows an embodiment for explaining a reader device that reads the electronic tag in accordance with the movement of the worker 1, and in FIG. 2, particularly shows a type in which the reader device is mounted on the worker himself. That is, the worker 1 wears the main body 1A supported by the waist belt. The main unit 1A includes a power source, a data memory device, a transmission device that transmits to a host computer (details will be described later) by radio waves (wireless LAN), a transmission device that can activate an electronic tag, and a plurality of reading sensor units. High frequency sources that supply different types of high frequency. A high-frequency receiving unit that analyzes high-frequency signals received by a plurality of reading sensor units. In order to satisfy this configuration, for example, a PDA device having a transmission / reception card capable of configuring an intranet can be used. The plurality of reading sensor units include a wristband type transceiver 1B wound around a wrist, a ring type transceiver 1C connected via the wristband type transceiver 1B, and a type transceiver 1D wound around an ankle. It is shown. Further, it is possible to form reading sensor portions on both the left and right wrists, both the left and right ankles, or fingers as desired. Furthermore, in the figure, 1B 'is a wristwatch type transceiver. The wristwatch-type transmitter / receiver also has a power supply and a wireless function to the host computer, and the band 1B "is formed in a coil shape, and both the radio wave to the electronic tag and the antenna for the wireless function to the host computer or The function of one antenna is given.

  In addition, by separating the reading sensor unit and the main body unit 1A, the sensor unit can be worn at places where it is not good for loads, such as arms and fingertips, and functions sufficiently as a sensor unit. Since the above-described electronic processing is performed by the belt-tightened main body 1A that does not become a burden even if the data is relatively heavy, an ideal reader device can be formed. However, if low power and high density are promoted in the future, it is possible to form a reader device that functions as a single device without being separated from the fingertip or arm.

  FIG. 3 is a perspective view showing the details of the entrance / exit A1, and A2 is a card-type electronic tag {the electronic tag is a tag formed of an IC chip with a large storage capacity and only the reflection of the radio wave depends on the reflection of the tag. It is used as a general term for contactless electronic tags that allow information to be read}. The card-type electronic tag is provided on the back surface and is attached to one corner of the entrance / exit A1 with an adhesive surface. In addition, information corresponding to the position of the doorway A1 is recorded on the card-type electronic tag. When the operator 1 passes through the entrance / exit A1, the transmitter / receiver of any one of the wristband type transceiver 1B, the wristband type transceiver 1B, the ring type transceiver 1C or the type transceiver 1D wound around the ankle and the card type The electronic tag reacts and the information is transmitted to the main body 1A. Further, the main body 1A can obtain information about the operator coming to the vicinity of the entrance / exit A1 to the host computer. If necessary, by providing separate card-type electronic tags inside and outside the entrance / exit A1, by monitoring the reaction time of the electronic tag, whether the worker has gone out through the entrance / exit A1, Alternatively, the host computer can clearly determine whether the employee has returned to work.

  FIG. 4 is a partial cross-sectional perspective view of the floor sheet B1 laid on the floor B described in FIG. In the figure, B2 is a lower sheet member, B3 is an upper sheet member, and B0 is an electronic tag.

The floor sheet B1 includes upper and lower sheets of a lower sheet member B2 and an upper sheet member B3 as shown in the figure, and electronic tags B0 are dotted at equal intervals between both sheets. The electronic tags B0 are not necessarily provided at regular intervals, and can be randomly scattered. The distribution amount of the electronic tag is preferably determined according to the communication distance of the electronic tag. That is, if the communication distance is short, it is effective to arrange them relatively adjacent to each other. If the communication distance is long, it is preferable to arrange them at an interval equivalent to the communication distance. Lower sheet member B2 and upper sheet member On the other hand, it is preferable that the electronic tag B0 is given a different code, and the positional relationship between the code and the floor sheet is registered in advance in a database in the host computer.
The floor sheet B1 and the worktable sheet C1 or the belt D1 are basically the same structure, and the worktable sheet C1 and the belt D1 communicate with the electronic tag more than the floor sheet B1. Select a type with a shorter distance (standard communicable distance). In addition, the work table sheet C1 and the belt D1 are more densely interspersed with the electronic tags than the floor sheet. The reason is to detect the movement of the operator's hand in more detail.

FIG. 5 is a partially broken enlarged perspective view of the guide plate described in FIG. In the figure, E is a board of the bulletin board, E1 is a character string, and E2 is a card type electronic tag E2 inserted between the character string E1 and the board E. The character string can basically be freely set, but the content to be transmitted in the work flow is preferable. In addition, as desired, a term for confirmation such as “registration permission”, “erroneous recognition deletion”, “yes”, “no” and an electronic tag corresponding to the term can be provided in the character string as a set. .
The guide plate configured as described above brings, for example, the wristband type transceiver 1B or the ring type transceiver 1C attached to the operator close to a desired character string. Further, when the character string is approached, the wristband type transmitter / receiver 1B or the ring type transmitter / receiver 1C is brought close to the misidentification deletion term. By doing so, the previous mistake can be deleted.
As described above, the bulletin board E has electronic tags recorded in a card format. If desired, the character string recorded in the electronic tag can be matched with the character string E1, so that it can be read by the wristband type transceiver 1B or the ring type transceiver 1C. Since the transmission data sent to the host computer matches the character string that the operator tried to touch, the host computer does not need to have a corresponding database. Also, if you move a pair of card-type electronic tags that have the same character string as the character string, you can select the correct electronic tag while looking at the character string, and freely place it while looking at the character string. Can do.
If desired, a character string is written on the surface of each sheet type shown in FIG. 4, and the relationship with the electronic tag close to the character string is recorded in a database in the host computer, so that a desired When the operator approaches the character string, the corresponding data can be sent to the host computer.

  FIG. 6 is an embodiment showing an example of an electronic tag of a type worn by an operator. In the figure, an operator is an apron type electronic tag group. The apron H is provided with 16 pockets, and the outer peripheral surface of the pocket is formed of a transparent material such as vinyl. A card-type electronic tag is inserted into this pocket. In this card-type electronic tag, a word “example: work start” related to work and a digital signal equivalent to the content of the word are recorded in an IC memory in the card-type electronic tag on the card surface. . That is, the card-type electronic tag recorded so as to obtain a digital signal substantially related to the contents of the card surface is inserted into this pocket. And preferably, a card in which all 16 different words with different contents are recorded is inserted and used. Also, if the content to be recorded changes, a new card with the desired content can be obtained by reinserting a different card as desired. On the other hand, a ring type transceiver 1C is mounted on the operator's finger. The operator can read the desired content by bringing the ring-type transceiver 1C close to the card-type electronic tag inserted in the apron. Note that the type of electronic tag to be mounted can be applied as it is to a light-reflective vest for ensuring nighttime safety, and can also be applied to a bag for use when going out. In addition, we can propose gloves, socks, shoes, etc. that are equipped with electronic tags. In this way, by providing electronic tags on accessories that are always worn, when attending a meeting between workers, members attending the meeting You don't have to know every single thing, just specify the time and place and ask the host computer to find out who is attending the meeting immediately.

FIG. 7 shows an embodiment showing a state in which a corresponding electronic tag is attached to a sewing cloth material. In the drawing, G1 is a first sewing cloth material, and an electronic tag is provided on one end side thereof. Similarly, G2 is a second sewing material, and this electronic tag is provided with an extension G5 for attachment on at least one end side. And this extension part G5 is formed with the material of a thin wire-like, and the electronic tag is attached by being entangled with the cloth material for sewing. The extension G5 also serves as an antenna for the electronic tag. If desired, the extension G5 is covered with an insulator, and is made of a heat-sealing material, so that the electronic tag can be easily attached by heating and pressing it against the mounted body. It becomes possible.
When the operator 1 approaches the sewing cloth material formed as described above and the ring-type transceiver 1C described in the embodiment of FIG. 2 approaches, the electronic tag installed on the sewing cloth material is react. As a result, for example, the worker 1 is informed that the approach to the sewing material G1 is transmitted to the main body 1A and further transmitted to the host computer by radio waves.
Further, as shown in the drawing, a plurality of electronic tags are attached to one sewing cloth material, and the plurality of electronic tags are assigned different numbers. By doing so, it can be understood that the worker 1 approaches the sewing cloth material and the side on which the reaction has come first is close to the worker 1 among the plurality of electronic tags. The direction is determined. Similarly, if an electronic tag with a different number is attached to one article, it is possible to determine the direction and the moving direction with respect to the worker. Further, if information such as direction and moving direction is not necessary, it is only necessary to provide one electronic tag for one article.

  FIG. 8 is an explanatory diagram showing an electronic flow of the electronic tag, the reader device, the host computer, and peripheral devices. First, an electronic tag approaching a preset distance is read by a reader device worn by an operator. As a result, the information unique to the electronic tag and the time information flow to the intranet network wirelessly (radio wave) via the reader device and are input to the server A1 (this input data is D1). On the other hand, when the electronic tag is provided in a small personal computer, an automation device, or a fax machine, the contents of each job are input to the server A1 via an online intranet. That is, the fax transmission result and time are input to the server A1 as information D1 '. Thereafter, it is input to the storage means described in the figure. The input electronic tag data, the data on which the electronic tag is attached to the fax, the time when the electronic tag data was obtained, and the time when the fax content record was input to the server A1 If it falls within the range of, i.e., if it is found to be common to the above time, for example, if it has a width of around 5 minutes, these data are correlated. Then make them recognize. This determination can be a work in the server. Based on such determination, it is recorded in the server that the worker 1 is near the fax at an arbitrary time and transmits the contents of the registered fax.

The above is an example of a fax machine, but the processed content and the worker who processed it can be recorded even with a personal computer cooperating with multiple people with the same mechanism.
Further, even in an automation machine (for example, the belt conveyor D), a person who has been involved in the production of a certain lot is automatically recorded by the above-described mechanism without recording it one by one.

  On the other hand, the electronic tag provided at the entrance / exit A1 reacts to the passing worker. In this case, it is unclear whether you entered the work room or went out, but if the indoor electronic tag record was just before its passage, you know that you left, and if the previous record is not in the room, It can be determined that the user has entered the room, and by configuring such a mechanism, the number of electronic tags installed can be reduced.

Next, the usage state of the bulletin board E will be described. It has been described with reference to FIG. 5 that the bulletin board E has the character string E1 and the card-type electronic tag E2 provided near the character string E1 associated with each other. Then, the worker brings the reader device closer to the character string in the bulletin board E, reads the electronic tag for the purpose of reporting and reporting the worker, and inputs the result to the server A1 via the intranet.
In the server A1, a database corresponding to the character string is recorded in advance, and only the number data of the electronic tag E2 has actually arrived at the server A1, but the database corresponding to the number data is sent to the bulletin board. Data similar to the described character string is substantially recorded in the server A1. By doing so, for example, the operator can record the content of the communication with one touch without describing the fixed report content in the daily report. The recorded time is also automatically recorded, and according to the degree of urgency, the recorded content is transmitted to the server A1 in real time rather than being transmitted near the end of the day, like a daily report. The administrator is further notified according to the contents. Alternatively, the administrator can check data with high urgency within a certain range, and can respond according to the situation.

The reader device described in detail with reference to FIG. 2 can further take the following forms as desired.
In addition to the above, the sensor unit, which is an element of the reader device, may be a shoe wearing sensor, a glove wearing type, a sock wearing type, a helmet wearing type, a hat wearing type, or the like. In addition, it is ideal that the main body 1A is provided in the same place as the sensor unit, but in order to solve the problem that the capacity of the power source and the shape and weight of the output amplifiers of various transmitters cannot be sufficiently reduced. In addition, as shown in FIG. 2, a separate type is one solution. Further, when the transmission output is large, it is preferable to provide it at a position as far as possible from the worker's abdomen and head. For example, it is preferable to have the worker so that positioning can be performed below the hip.

Effects of the Invention The present invention defined in claim 1 has the following effects.
When capturing the movement of a moving object with a sensor, the sensor is generally fixed, and when the moving object passes or approaches, the sensor reacts and moves. It is usually done to identify the movement of the. In such a case, it is effective when the number of moving objects is sufficiently large. However, for example, when the number of workers is small as compared with the work space, the number of leader devices is large, which greatly increases the work cost. Therefore, a reader device is attached to an operator who is a moving object, and an electronic tag that reacts to the reader device is attached to a desired position in a relatively wide space, so that the reader device needs only the number of workers. On the other hand, electronic tags that need to be provided in large quantities are advantageous in that they are extremely small in size and “generally about rice grains” and can save installation costs and installation space. Furthermore, even when communicating with the host computer, if the number of reading sensors is large, the number of wireless systems or wired systems is required, so that the installation cost and the installation space become huge. However, the problem can be solved by adopting the configuration of the present invention.
In addition, a small electronic tag is installed in the workplace finely and the position of the electronic tag is read by the reader device. Therefore, unlike a conventional method of grasping work by installing a camera, it becomes a shadow of a person or a device. The situation is such that the behavior is completely unknown. In other words, it is possible to obtain information such as shadow portions and subtle timing of hand handling, which was impossible with a camera. Further, the timing information can be used as a trigger for image separation for each work content of the camera information used together.

The present invention defined in claim 2 has the following effects.
By configuring the reader device so that the reading sensor unit can be mounted on the tip side of the operator's leg, it is possible to collect information linked to the number of steps.

The present invention defined in claim 3 has the following effects.
Among the configurations of the reader device, the reading sensor unit is configured so that it can be attached to the tip side from the operator's arm, so that the movement related to the swinging of the left and right hands is read, and the information related to the left and right Collection is possible.

The present invention defined in claim 4 has the following effects.
Since the plurality of electronic tags are configured to be interspersed in a sheet-like material at a constant interval, there is no need to attach the electronic tag, and since it is in the form of a sheet, a specially attached electronic tag There is no need for landmarks, and positioning of the electronic tag can be completed simply by laying it down where it is needed.

The present invention defined in claim 5 has the following effects.
A plurality of electronic tags are formed on a sheet-like material, and a meaning corresponding to the electronic tag is written in a reading area of an arbitrary electronic tag of the sheet-like material. By bringing the reader device provided by the worker closer, the reading sensor unit worn by the worker can read the data corresponding to the meaning. You can quickly input standard sentences that are indispensable for communication and daily reports, and there is no need to input the time and the input person one by one, and easy-to-understand daily reports (or real-time responses) are obtained. It is done.

The present invention defined in claim 6 has the following effects.
By configuring the host computer to collect both the data read by the reading sensor unit worn by the worker and the information indicating the work content in association with the time data, not only a record of the worker's behavior Since the work contents obtained in association with the behavior of the worker are recorded in association with each other, not only the movement of the worker but also the record corresponding to the result can be obtained together, so that an accurate behavior record of the worker can be obtained. .
