Description

The present invention is a technology related to safety management when performing non-stationary processing such as repair work or modification work on production line equipment. In particular, the present invention is a technology that can improve reliability and work efficiency when canceling condition settings that have been set as non-stationary states.

When carrying out repair or modification work on production line equipment, the following procedures are generally carried out to ensure safety before construction begins.
Before construction, first, each piece of equipment is stopped and set to an unsteady state, and various related parties such as factory operators, maintenance personnel, and construction workers confirm that each piece of equipment is in a safe state. At this time, in order to declare that it is safe to enter the production line, safety measures (called condition setting) are taken, such as hanging condition setting tags (operation prohibition tags) on switches that are in the "OFF" state to ensure that switch operation is prohibited.
In addition, when the work is completed and the equipment is put back into operation, all the condition setting tags attached to the switches of each piece of equipment are collected prior to restarting the equipment. Then, once the condition setting tags attached to the switches have been removed, it is determined that no one has entered the production line, and the switches for the entire line are turned "ON" as a safety measure (called condition setting release or setting release).

Here, when carrying out repair or modification work, there are many production lines that have a large number (for example, 400 locations) of equipment that is subject to safety measures, such as switches, valves, mechanical stoppers, etc. In such cases, it has traditionally taken a lot of time and effort to check the safety of all the equipment using condition setting tags and to confirm that the safety measures are being taken according to the standards.
In addition, in recent years, factory operators and maintenance workers are often working with a small number of people. For this reason, situations such as construction workers waiting for their turn to be instructed by maintenance workers on where to hang condition setting tags can occur, and there is a need to strengthen cooperation between construction and maintenance. Furthermore, due to the decrease in skilled workers, it has become essential to pass on skilled skills. As such, there are cases where reliability is lacking in terms of reliable condition setting and release for safety management.

Conventionally, there is a technology related to work safety, for example, the technology disclosed in Patent Document 1. This technology allows only specific people to enter a specific area and efficiently manages entrance and exit. Specifically, this technology is an entrance and exit management system in which workers wear helmets equipped with IC tags and access the information on the IC tags at the site gate to manage the entrance and exit of workers to and from the site.
Furthermore, Patent Document 2 discloses a technique for managing safety by having workers carry transceivers and detecting whether or not there are any workers within a danger zone of a construction machine.
Furthermore, although not related to production lines, there is also a technology described in Patent Document 3. Patent Document 3 discloses a safety monitoring system that observes the amount of rainfall, wind speed, river water level, etc. to determine the presence or absence of danger at the work site and monitors the presence or absence of causes that pose a direct danger to workers.

However, none of the techniques in Patent Documents 1 to 3 is intended for setting and canceling conditions during repair or modification work on production line equipment, and they do not address reliable, easy, and efficient safety management of condition setting and cancellation.
In response to this, Patent Document 4 discloses a system for preventing erroneous operation of equipment such as a plant, which prevents erroneous operation of equipment such as power supply equipment in advance.
The technology described in Patent Document 5 is premised on attaching a fixed tag to each piece of equipment. Patent Document 5 also describes a method of performing a comparison between the information on the fixed tag, a list such as a condition setting list, and information on an RFID tag attached to the condition setting tag at the site. This allows for reliable, easy, and efficient safety management of condition setting and cancellation.

JP 2006-22524 A JP 2006-72719 A JP 2009-271628 A JP 2006-146749 A JP 2016-192206 A

However, the technology described in Patent Document 5 reads three pieces of information on-site: the fixed tag attached to the equipment, the RFID tag attached to the tag, and the list information. This means that RFID's unique feature of being able to read multiple items at the same time cannot be used, and the efficiency is insufficient, especially for operators with a certain level of experience.

In other words, the technology described in Patent Document 5 requires reading the fixed tag of the equipment, the RFID tag of the tag, and the list data in front of each piece of equipment. For this reason, for example, if an inexperienced worker tries to perform this at a site where there are many similar pieces of equipment, it may take a long time to find the target equipment. In other words, there is a problem that it is difficult to narrow down the equipment. In addition, the location of the target equipment is not always a place where the equipment and switches are neatly lined up and easy to find, such as an operator's cab or an electrical room. There may be cases where it is necessary to find a valve for which conditions should be set or released, or a switch for which conditions should be set or released on the operation panel of an equipment hidden behind a large machine, among the complex piping at the site. And a common pattern of past mistakes is insufficient confirmation due to the haste to start up quickly, but even if the location is known, performing three-point matching can actually take more time.

Furthermore, since there are a large number of target locations, for example, 400 or more locations, there is an issue that performing the above three-point matching work for each piece of equipment takes a lot of time.
Similarly, in the technique disclosed in Patent Document 4, there is a problem in that it takes time to perform the matching for each device on-site.
Another issue is that during startup preparation, maintenance personnel frequently contact the system to inquire about the status of the settings release, which often places a heavy burden on the cab operator.

The present invention was made with the above points in mind, and aims to further improve the reliability and work efficiency of matching work in safety management when performing non-stationary processing on a production line.

In order to solve the problem, one aspect of the present invention is a safety management method in which, when performing non-stationary processing such as repair work or modification work on a production line, multiple pieces of equipment selected from the equipment of the production line are set to a non-stationary state, a condition setting tag is attached to the equipment to be in the non-stationary state to set the equipment to a condition setting state, and when the non-stationary processing is completed, the condition setting tag attached to the equipment is collected and set to a setting release state. The method includes an RFID tag attached to the condition setting tag and storing information about the equipment corresponding to the attached condition setting tag, a reader capable of reading information in the RFID tag by near-contact communication, a memory unit that stores a condition setting list having information about at least the condition setting and setting release states of the equipment to be in the non-stationary state, and the RFID tag read by the reader. The method includes a verification unit that compares the information with the condition setting list and detects, by computer processing, data in the condition setting list that corresponds to the equipment identified by the information on the RFID tag, and a setting update unit that changes, by computer processing, the setting release state of the equipment in the data corresponding to the equipment identified by the information on the RFID tag detected by the processing of the verification unit to a state in which the condition setting tag has been collected. The method collects the multiple condition setting tags placed on each piece of equipment, reads the RFID tag attached to each of the multiple condition setting tags after collection with the reader to execute the processing of the verification unit and the setting update unit, and checks whether the setting release of the target equipment has been completed based on the data in the condition setting list after the execution.

According to this aspect of the present invention, when canceling settings, the RFID tags attached to the collected condition setting tags are read in sequence at the same location to perform a matching operation. As a result, the reading operation is time-saving, and the read information is also automatically matched, ensuring the reliability of the matching. In particular, compared to performing matching operations each time the equipment is moved to each facility on-site, this aspect of the present invention performs the matching operation collectively, making it possible to perform the matching operation stably and improving the reliability of the matching operation. Furthermore, as described above, this aspect of the present invention also improves work efficiency.

The results of the comparison are stored as a condition setting list. Therefore, when using a cloud (server), it is possible to simultaneously view the setting release status, including maintenance. This reduces the need for radio and telephone communication to understand progress, and also has the effect of allowing the operator in the cab to concentrate on their work during test runs.

Next, an embodiment of the present invention will be described with reference to the drawings.
(Safety Management System)
A safety management system used in the safety management method of this embodiment will be described.
As shown in FIG. 1, the safety management system of this embodiment includes a condition setting tag 1, a mobile terminal 3, a PC 5 (personal computer), and a server 4.
The mobile terminal 3, the PC 5, and the server 4 are configured to be capable of wireless communication via the Internet or other known communication means.

<Condition setting card 1>
For example, an ID or a name of a target facility (such as a switch or a valve) is written on each condition setting tag 1. The ID refers to an identifier such as an identification symbol that identifies the target.
In addition, an RFID tag 2 is attached to the condition-setting tag 1. The RFID tag 2 is fixed to the condition-setting tag 1 with tape or the like. The RFID tag 2 may be detachably attached to the tag 1. The RFID tag 2 is, for example, an IC tag, and includes a CPU, an antenna, and a memory unit.
Information on the corresponding equipment is stored in the RFID tag 2. For example, as shown in Fig. 2, the RFID tag 2 stores information such as the ID of the corresponding equipment and the location number.

<Server 4>
The server 4 includes a storage unit 7, a collation unit 4A, and a setting update unit 4B.
The storage unit 7 stores data of a condition setting list 7A and map information 7B.

[Condition setting list 7A]
The condition setting list 7A, as shown in FIG. 3, for example, has data for each piece of equipment that makes up the production line, and each piece of data has items in which information such as "position no.", "ID", "condition setting status", and "setting cancellation status" are stored.
The location number is a number given to the facility location on the map.
The ID is an identifier (ID) given to the equipment.
The condition setting status includes setting information and set information. Condition settings are set for equipment that is to be set to a non-steady state during construction. The non-steady state is usually a stopped state. The "setting" status is information that is set in advance for equipment to which condition setting tag 1 is hung. In Figure 3, ◎ indicates equipment that has been set. "Done" information is information on whether or not condition setting tag 1 has actually been hung on equipment. In Figure 3, "○" is a status display indicating that condition setting tag 1 has been hung.
The setting release status is a field that displays the status of whether or not the condition setting tag 1 has been collected.

In this way, the condition setting checklist contains information such as the equipment name and the list status (tag preparation, condition setting, setting cancellation, etc.). Items with different condition setting timings should be identified by shape or color, and items that require special attention (such as items that are not good if done in a random order) should be identified by color or shape.

[Map information 7B]
The map information 7B is information for displaying a map relating to the position of each piece of equipment in the production line.
[Collation unit 4A]
The matching unit 4A is activated when the tag information read from the RFID tag 2 is input.
The collation unit 4A performs a condition setting process and a setting release process.

First, the condition setting process will be described.
When the collation unit 4A receives a setting processing command, it searches the data in the condition setting list 7A using the ID of the tag information as a key, and determines whether data with that ID is present. If data is present, it determines whether the status of "◎" is set in the setting column for the condition setting status of that data. If the conditions are met, the process proceeds to the setting update unit 4B for processing the setting information. On the other hand, if the conditions are not met, an error message is sent.

Next, the setting cancellation process will be described.
When the collation unit 4A receives a setting release command, it searches the data in the condition setting list 7A using the ID of the tag information as a key to determine whether data with that ID exists. If data exists, it determines whether the status of "◎" is set in the setting column for the condition setting status of that data. If the condition is met, the process proceeds to the setting update unit 4B to process the release information. On the other hand, if the condition is not met, an error message is sent.

[Settings Update Unit 4B]
When the setting update unit 4B acquires the setting information from the collation unit 4A, it sets the status of "O" (status of tagged) in the "Completed" column of the condition setting status for the data of the corresponding ID.
Furthermore, when the setting update unit 4B obtains the release information from the collation unit 4A, it sets the status of "○" (status of the bill having been collected) in the "Release Setting" column for the data of the corresponding ID.
Here, the processing of the collation unit 4A and the setting update unit 4B may be provided in the terminal 3, the PC 5, etc., but assuming that there are multiple terminals 3, etc., the processing is executed commonly by the server 4.
For the same reason, the condition setting list 7A is also set in the server 4.

<Mobile Terminal 3>
As shown in FIG. 4, the terminal 3 includes a display unit 3A, an operation unit 3B, a CPU 3C, a storage unit 3D, a communication unit 3E, and a reader processing unit 3F.
[Reader processing unit 3F]
The reader processing unit 3F is a processing unit that performs near-contact communication with the RFID tag 2, and may have a known configuration. The communication is performed using, for example, Bluetooth (registered trademark) technology, which is one of the short-range wireless communication standards for digital devices. The reader processing unit 3F may have a function of writing to the RFID tag 2.

[Memory unit 3D]
As shown in FIG. 1, the storage unit 3D stores programs such as a map processing unit 3Da and a list processing unit 3Db in the form of applications.
[Communication unit 3E]
The communication unit 3E is a functional unit that performs wireless communication with the server 4 and the like.

[Map processing unit 3Da]
When the map processing unit 3Da receives tag information from the RFID tag 2 via the reader processing unit 3F, it acquires map information 7B from the server 4 and performs processing to display the positions of each equipment for which conditions are set, including the equipment position corresponding to the RFID tag 2, as a map on the display unit 3A. It is not necessary to display the positions of all equipment for which conditions are set, and it is sufficient that at least the positions of the selected equipment and equipment in the vicinity are displayed. This map display processing may employ a known processing method. For example, the information of the condition setting list 7A is read onto the map information 7B including the equipment positions of the target production line, and the layer of the position number for the equipment specified in the condition setting list 7A is superimposed and displayed as shown in FIG. 4. Note that in FIG. 4, the equipment map of the production line itself (passages, etc.) is omitted for ease of understanding.
In the example of Fig. 4, the location number of the facility corresponding to the tag information is illuminated and displayed. In the example of Fig. 4, the location number of the facility for which the condition setting status of the condition setting list 7A is set to "set" is displayed in a double circle. In the example of Fig. 4, the navigation information to the facility for which the condition setting is set with the next number is also displayed.

The map processing unit 3Da is also configured to be able to execute the above process by selecting the location number of the equipment displayed in the condition setting list 7A. For example, the map processing unit 3Da is configured to be activated by selecting the location number item while the condition setting list 7A is displayed on the display unit 3A.

[List processing unit 3Db]
The list processing section 3Db executes processing relating to the condition setting list 7A.
The list processing unit 3Db executes, for example, the following processes.
When list display is selected, the list processing unit 3Db acquires data of the condition setting list 7A from the server 4, and displays the condition setting list 7A as shown in FIG.
In addition, when tag information is input from the RFID tag 2 as condition setting, the information is transmitted to the server 4, and update information for the updated list is input, and an update process for the displayed condition setting list 7A is performed. As a result, the status displayed is changed from "Completed".
Furthermore, when tag information is input from the RFID tag 2 as a setting cancellation, the information is transmitted to the server 4, and update information of the updated list is input, and an update process of the displayed condition setting list 7A is performed. As a result, the status of "setting cancellation" is changed and displayed.

<PC5>
The PC 5 is disposed in a central control room such as a driver's cab. A reader device 6 capable of inputting and outputting information from the RFID tag 2 is connected to the PC 5. The PC 5 may be configured as the terminal 3 having the above-mentioned configuration.
The PC 5 includes a condition setting unit 5A that performs a process of setting the "set" status of the condition setting in the condition setting list 7A. That is, the PC 5 processes the condition setting list 7A to create basic data.
In this embodiment, it is not essential to assign a fixed tag to each piece of equipment.

(Safety Management Methods)
The safety management method of the present embodiment is executed by utilizing the above-mentioned safety management system.
<When setting conditions>
First, the main steps of the safety management process for setting conditions will be described below.
(1) Prepare a condition setting tag 1 with an RFID tag 2 attached to hang it at a location where conditions are set (operation part of the equipment). In some cases, 400 or more tags will be prepared.

(2) The prepared condition setting tag 1 with the RFID tag 2 is read by a reader device in the driver's cab, and a condition setting table is created in the PC 5, and a setting process is performed for the "Set" status of the condition setting in the condition setting list 7A. Then, by referring to the condition setting list 7A, the equipment for which conditions are to be set becomes clear.
(3) Move to each actual facility, set the conditions (unsteady state) for each facility, and hang a condition setting tag 1 with an RFID tag 2 on the corresponding facility.
During this process, if the location of the tag becomes unknown, the RFID tag 2 attached to the next condition setting tag 1 to be hung is read by the reader processing unit 3F of the terminal 3, and a map is displayed on the terminal 3, and the location can be confirmed using the map display. Since the condition setting operation for each piece of equipment is performed by one person, the worker generally has the skills to identify the location of the equipment without checking it against a map. In addition, even young workers or those who have been transferred can easily identify the location if the map display is available.

(4) After hanging the condition setting tags 1, input "condition setting complete" on the terminal 3 to update the contents of the condition setting list 7A. In other words, turn on the "Completed" status in the condition setting list 7A. Note that this input timing for turning on the "Completed" status does not have to be done every time a tag is hung. In this embodiment, the user confirms and inputs that the prepared tags have been hung and used at each work interval.

(5) The administrator refers to the condition setting list 7A on the PC 5 to grasp the situation in real time.
If the condition setting is to be added or re-set (when it is necessary to set the condition again after it has been released once), the condition setting is registered by processing in the PC 5 in the driver's cab. Also, it is possible to check on the terminal 3 whether the creation and registration of the condition setting list 7A has been completed.

If all the "Done" statuses corresponding to the "Set" statuses in the condition setting list 7A are set, it is clear that the condition setting is complete. Also, since the original data of the condition setting list 7A is stored in the server 4, the latest status can be confirmed in various places, and there is no need to inquire at the driver's cab. This is also true when canceling the settings.
Furthermore, if there are any necessary documents such as standards and related books other than the condition setting list for checking, they can be linked and stored in the server 4 for viewing.

<After setting conditions>
Once the conditions have been set, workers carry out the actual repair or modification work (non-routine processing).
<Cancel>
Once the construction is completed, the conditions must be lifted and the equipment made ready for use.

First, while referring to the condition setting list 7A displayed on the terminal 3, the user goes to the site and collects the condition setting tags 1 that have been hung on each piece of equipment. If there are many tags to be collected, not all of the tags are collected at once.

In this embodiment, at the end of the tag collection work, the process selection of the list processing unit 3Db is operated to the setting cancellation setting in a place such as the driver's cab or a rest area near the work site, and each RFID tag 2 attached to the multiple condition setting tags 1 that have been collected is read in order by the terminal 3. This automatically activates the comparison unit 4A and the setting update unit 4B, and the status of the setting cancellation column on the condition setting list 7A is automatically updated to collected. The display of the condition setting list 7A displayed on the terminal 3 is also automatically updated.

After that, the updated list display allows the user to confirm that they have not forgotten to retrieve the tags from the locations they visited to deactivate within a section. Also, since the RFID is not read every time at the equipment location of each site, the processing time is shortened. Furthermore, by reading the information all at once, each RFID tag 2 can be read stably, improving reliability.
In addition, operators in the cab or electrical room can also grasp the progress. In other words, list information can be shared without having to return to the cab, and traffic flow is smoother. In addition, by allowing others to grasp the progress, unnecessary communication can be reduced, which has the effect of allowing them to concentrate on canceling settings and preparing for test runs.

Furthermore, by taking advantage of the characteristics of the RFID tag 2 and reading a plurality of tags at the same time as described above, it is possible to significantly reduce the time. It is preferable to provide a display of a list of tags that have not yet been released, so that users can easily notice that they have forgotten to release the tag.
Then, power is turned on and test runs are started for the section where collection of condition setting tags 1 has been completed. Furthermore, once it has been confirmed that all tags on the list have been returned, the main switch in the driver's cab is turned on to start operations.

As described above, by adopting this embodiment, it is possible to improve reliability and work efficiency when setting and canceling conditions when carrying out repair work or modification work on production line equipment.

Here, this embodiment was applied to the regular maintenance of an actual hot rolling line. It was confirmed that the time required to prepare the plates the day before was reduced by 15%. The time required to set the conditions was roughly the same. However, if there was any uncertainty, it is believed that this amount could be reduced by checking the map. The time required to check the plates after the settings were released was reduced by 75%. The comparison was made with a case in which the management method in Prior Art 5 was applied.
