Description

  The present invention relates to an operation prohibition tag and an operation prohibition tag management system for displaying that the operation of devices such as a circuit breaker related to the operation of various devices and systems at a work site is prohibited.

  In order to maintain safety in factories or work sites, the use of operation prohibition tags is known. For example, in order to prevent an erroneous operation of a power distribution breaker attached to an electrical wiring in a factory or the like, it is common to hang an operation prohibition tag on the front surface of the circuit breaker (see Patent Document 1). The operation prohibition tag indicates that the operation is prohibited on the premise that the circuit breaker is cut off, and the name of the company belonging to the operator, that is, the person who suspended the tag, the name of the operator, etc. Yes.

  In addition, not only one person works on the assumption that the same circuit breaker is broken, but the work may be performed at a plurality of other locations related to the circuit breaker. In this case, another operator's operation prohibition tag is hung on the same circuit breaker. Often, 3 to 5 operation prohibition tags are hung in one place.

  This operation prohibition tag ensures the safety of workers who work at the site, and the facility safety management officer at the work site patrols the site to check whether the operation prohibition tags are suspended as planned. Must be confirmed. In this case, the facility safety manager will check visually, but when multiple operation prohibition tags are hung in one place, this confirmation / check will require a lot of labor, and there will be no check omissions. Danger is a concern.

  For example, as shown in a front view in FIG. 6A and a side view in FIG. 6B, a hanging string 12 is provided at the upper end of the operation prohibition tag 11, and an operation prohibition mark 13 is shown on the surface. Has been. Furthermore, the company's name AAA14 and the worker's name 15 are listed.

  As shown in FIG. 7, the operation prohibition tag 11 having such a configuration has three circuit breakers, such as a first circuit breaker 17a, a second circuit breaker 17b, and a third circuit breaker 17c, installed at positions adjacent to each other. It is hung by the 1st-3rd hooks 18a, 18b, and 18c provided in each lower part or the circuit breaker front. In FIG. 7, three operation prohibition tags 11 are hung on each hook 18a, 18b, 18c as shown in the figure, and the operation prohibition tags 11 of each hook are shown in FIG. This is called group C. There are various types of circuit breakers. For example, the average distance between the centers of adjacent circuit breakers is 150 mm to 200 mm, and the distance between the side surfaces is 50 mm.

  In this case, as shown in FIG. 7, when three operation prohibition tags 11 are hung on each of the hooks 18a, 18b, 18c, the operation prohibition tags 11 in the groups A, B, C overlap each other. The operation prohibition tags 11 between the groups also overlap each other.

  As mentioned above, the facility safety manager in the field is responsible for checking and supervising whether or not the operation prohibition tag is properly installed and managed, and for that purpose, the inspection is carried out.

At this time, the confirmation of the operation prohibition tag must be visually read by distinguishing the data of the operation prohibition tag 11 suspended for each of the A group, the B group, and the C group, that is, for each circuit breaker. As a result, in tags within the same group that overlap each other, the data of the tags hidden in the front tag is read out, or in adjacent tags, it is mistaken as a tag of a group different from the original group. Inaccurate reading will result in serious problems in safety confirmation.

  An embodiment according to the present invention will be described with reference to the drawings. FIG. 1 is a view showing a bill constituting one embodiment of the present invention. Detailed description of the same parts as those in FIG. 6 is omitted. In other words, the operation prohibition tag 11 includes the name of the company 14 performing the construction, the name of the worker 15 and the like, and a tag wireless tag 16 in which management data is stored. Although the figure shows an example in which the tag wireless tag 16 is pasted on the back side of the operation prohibition tag 11, it can be incorporated in the tag.

  As data stored in the wireless tag 16, at least identification data that is a unique code unique to the operation prohibition tag is stored. In addition, the wireless tag 16 may store data such as a company name and a worker name associated with the identification data.

  Reading data stored in the tag wireless tag of the operation prohibition tag in which such a tag wireless tag is incorporated can be performed in a non-contact manner by radio wave transmission / reception using a so-called reader / writer. Now, a situation when reading an operation prohibition tag in which such a tag wireless tag is incorporated will be described with reference to FIG. The A group, the B group, and the C group in the figure correspond to the groups shown in FIG. 7, and illustrations and explanations of portions that overlap with FIG. 7 are omitted.

  Here, three operation prohibition tags 11a, 11b, and 11c are installed in each group corresponding to a circuit breaker (not shown). Each of the operation prohibition tags 11a, 11b, and 11c is substantially the same as the configuration shown in FIG. 6, and each of the operation prohibition tags 11a, 11b, and 11c includes a wireless tag that stores various data, but is not provided with a hanging strap.

  If the reader / writer 19 separates and reads the operation prohibition tags 11a, 11b, and 11c of each group, for example, when reading the data of the operation prohibition tag 11b of the B group in FIG. Since they are close to each other, the data of the operation prohibition tags 11a of the A group and the C group that should not be read as shown by the dotted line are also read.

  Therefore, in the present invention, as shown in FIG. 3, the operation prohibition tags 11a, 11b, and 11c of these groups are stored in the first folder 20a, the second folder 20b, and the third folder 20c, respectively. The folders 20a, 20b, and 20c are formed in a box shape having an upper end opened. A first position wireless tag 21a, a second position wireless tag 21b, and a third position wireless tag 21c are attached to the front surface of each folder 20a, 20b, 20c. Various data such as data specific to the corresponding circuit breaker corresponding to the installation position of each folder and data specific to the installation position are stored in the first position wireless tag to the third position wireless tag 21c.

  In FIG. 3, the position wireless tag is attached to each folder.

This makes it possible to specify the circuit breaker to be checked. In addition, various data stored in the wireless tags of the three operation prohibition tags 11b stored in the second folder 20b are read.

  In this way, a check is performed by the same operation for each group. However, since a plurality of operation prohibition tags are stored in the folder, they are not separated as shown in FIG. 2 and FIG. Only operation prohibition tags stored in folders for each group are to be read. For this reason, the radio wave intensity from the reader / writer 19 may be set to an intensity for reading only each folder. In this way, it is possible to read data accurately without adjacent operation prohibition tags being mixed and reading data.

  Now, a management system according to the present invention will be described with reference to FIG. Each of the first folder wireless tag 21a to the third folder wireless tag 21c has individual number information. Each wireless tag of the operation prohibition tag also has individual number information. When an operator starts a new operation and inserts an operation prohibition tag into the folder, and when the inserted operation prohibition tag is taken out of the folder, the operation prohibition tag administrator uses the reader / writer 19 to set the wireless tags 21a of the folders 20a to 20c. ~ 21c and the wireless tags of the operation prohibition tags 11a to 11c inserted in the folder are collectively read.

  The read information is transmitted via the wireless communication terminal 22 to the operation prohibition tag management system computer 23 which is an operation prohibition tag management device. The operation prohibition tag management system computer 23 compares the previous operation prohibition tag folder read information stored in the database 25 with the operation prohibition tag presence / absence detection unit 24, and stores and removes the operation prohibition tag in the folder, that is, Detects the presence or absence of operation prohibition tags.

  The detection information is newly stored in the database 25, transmitted to the reader / writer 19, and displayed on the reader / writer 19. The operation prohibition tag administrator can confirm that the operation storage / extraction processing has been performed correctly by checking the storage / extraction information of the operation prohibition tag displayed on the reader / writer 19. At this time, if storage or extraction information of an unscheduled operation prohibition tag is displayed, it can be understood that the operation prohibition tag has not been processed in a predetermined procedure.

  The operation prohibition tag information registration unit 26 performs initial registration of the operation prohibition tag folder 20 and the wireless tag of the operation prohibition tag 11, and the operation prohibition tag folder 20 stores operation prohibition tag attachment location information and the operation prohibition tag. 11 is registered with information on the owner of the operation prohibition tag, serial number information for each owner, and the like.
