Description

  The present invention relates to an on-site control / monitoring apparatus that manages operations associated with operation and monitoring of plant equipment and maintenance and inspection of equipment.

  In general, for the operation of plant equipment such as industrial plants and power plants, a control device for monitoring and controlling the plant equipment is provided, and an operator console with a display device and an input device installed in a central operation room by the operator is provided. The control operation is performed using a remote control operation performed by outputting a control command via the control device, or automatic control using a plant operation control panel. In addition, in the case of equipment maintenance, inspection work, or when an abnormality occurs, in addition to remote control operation from the central operation room, individual direct operation of plant equipment is performed by field workers. Conventionally, when a field worker performs individual direct operation of plant equipment for maintenance or inspection work of plant equipment or unsteady operation such as when an abnormality occurs, operation restrictions on the plant equipment are implemented. When restricting operation, install a tag to notify the operation restriction in the vicinity of the plant equipment at the site and operate the system on the console screen to restrict remote control operations from the central operation room. There was a setting for restriction (called billing setting).

  FIG. 9 shows an example of the conventional billing setting operation. The operation restriction of the plant equipment is such that the field worker 22 installs the tag 13 for notifying the operation restriction of the plant equipment 20 in the vicinity of the equipment on the work site and restricts the remote control operation from the central operation room to the plant equipment 20. In order to do this, it is necessary to contact the operator 21 in the central control room and perform a setting operation to limit the operation on the site control / monitoring device. The operation restriction setting operation was performed by the operator 21 inputting the billing setting of the target plant equipment using a screen such as a billing setting screen displayed on the input / output device 12 of the central operation room. . In addition, because information such as the period and reason for restricting operations was manually communicated and managed, even if the deadline for removing the tag has passed or it is possible to remove it, it will not be removed, and it will recognize the removal-missed tag It took time to.

  Note that “tagging” refers to the operation of placing a tag to notify the operational restriction when restricting direct operations on plant equipment, and “tagging setting operation” is remote operation from a central control room or the like. This is an operation for setting the billing using an input / output device such as a console by the billing function on the system of the on-site control / monitoring device.

In Patent Document 1, an operation personal computer for operating and monitoring plant equipment and a wireless LAN transmission / reception device are installed in the field, and the operation personal computer is used for operation and monitoring of the plant equipment on site. Discloses an example of an on-site monitoring / operating device that enables setting / cancelling of the tagging operation from the site.
JP 2003-216231 A

  In the operation of conventional plant equipment, there was a mixture of individual direct operation of plant equipment by field workers and remote operation by screen operation using the console of the on-site control / monitoring device installed in the central control room. . Therefore, when restricting the operation of plant equipment, it cannot be centrally restricted, and it is necessary to set up the tagging on site control / monitoring equipment as well as on-site equipment. There was a problem that the procedure of was complicated.

  In addition, double management of on-site actual billing operation and billing setting operation on the system was necessary. The on-site monitoring / operation device disclosed in Patent Document 1 can also be used for setting up bills on site, but it also uses actual bills and requires double management. As a result, erroneous operations occur due to time differences between on-site actual billing operation and billing setting operations on the system, and mismatching restrictions due to billing / removal omissions, etc., resulting in equipment damage and loss of raw materials and products. There was a risk of being connected.

  The present invention has been made in view of the above points, and an object thereof is to provide a field control / monitoring apparatus capable of centrally managing billing information related to operation restrictions on plant equipment.

  In addition, the tagging device reads the tag information recorded on the wireless IC tag of the tag, and transmits the IC tag reader provided at the tag placement position and the tag information read by the IC tag reader to the control device. Means, tag information storage means for storing the tag information read by the IC tag reader, and tag information management processing means for storing the tag information read by the IC tag reader in the tag information storage means and managing the data.

  According to the present invention, without restricting the conventional on-site billing operation procedure, the operation restriction information to the plant equipment is transmitted to the control device at the same time as the actual on-site billing operation, thereby centralizing management of the operation restriction information Is possible. As a result, it is possible to omit the billing setting operation on the system by operating the screen of the console, and it is possible to display the billing status at the site and leakage of the removal of the bill on the console screen of the central operation room. Can be easily confirmed. Furthermore, since the on-site operation of the plant equipment and the remote operation from the console screen can be restricted and released in synchronization, erroneous operation can be prevented and safety can be improved.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 shows a configuration example of an on-site control / monitoring apparatus according to this example. The configuration of this example will be described with reference to FIG. The on-site control / monitoring device according to this example collects information about the plant equipment 20 and connects to the control equipment 11 that performs control, and the control equipment 11 via the network 17, and the operator monitors and controls the plant equipment 20. The input / output device 12 includes a display device such as a monitor that displays a screen for performing the operation and an input device such as a keyboard, a mouse, and operation buttons. As an output device, a voice output device 18 or an alarm device for notifying the state or abnormality of the plant equipment can be provided.

  Next, the configuration of the billing device 14 will be further described. FIG. 2 shows a configuration example of the billing device 14. The bill hanging device 14 according to this example is a device for reading, displaying, and managing the operation restriction information of the plant equipment by installing it on the site and arranging the bill.

  The billing device 14 of this example includes an IC tag reader 41 that reads information of the wireless IC tag 31 added to the tag 13, and the wireless communication means 42 of the IC tag reader 41 and the wireless communication means 32 of the wireless IC tag 31. By performing wireless communication, information written in the IC tag is read and written. The tagging device 14 is provided with tag information storage means 44 for storing tag information read by the IC tag reader 41, and stores the read tag information as tag information storage data. The tag information read by the IC tag reader 41 is stored in the tag information storage unit 44 by the tag information management processing unit 43 and delivered to the transmission processing unit 45. The transmission processing unit 45 transmits the tag information input from the tag information management processing unit 43 to the control device 11. Furthermore, the tagging device 14 of this example is provided with a display device 48 and an input device 49. The tag information storage means 44 is referred to by the tag information display processing means 46, and the display device 48 is based on the tag information storage data. The operation restriction information is displayed, and the information in the tag information storage unit 44 is rewritten based on the information input from the input device 49 by the tag information editing processing unit 47. The rewritten tag information is transmitted by the tag information management processing means 43 to the control device 11 via the transmission processing means 45.

  Next, the structure of the bill hanging device 14 according to this example will be described. FIG. 3 is an explanatory diagram showing a structural example of the bill hanging device 14. 3, FIG. 3 (A) is a front view of the bill hanging device 14, and FIG. 3 (B) is a sectional view taken along lines a and a ′ in FIG. 3 (A). The bill hanging device 14 according to this example includes a holder 51 for arranging and fixing the bill 13 on the front surface of the base plate 50, a display device 48, and an input device 49, and an IC tag reader 41 on the back surface of the base plate 50. The display device 48 may be any device that can display the information of the IC tag, such as a liquid crystal display or electronic paper. The input device 49 refers to information on the displayed IC tag, and is used by a field operator to correct or add information, and includes a keyboard and a touch panel.

  3 shows an example in which three combinations of the holder 51, the display device 48, the input device 49, and the IC tag reader 41 are configured. However, the position of the site where the bill hanging device 14 is installed and the target device. What is necessary is just to comprise by the number according to the situation. In this example, a plurality of input devices 49 are provided in accordance with other devices. However, one input device is provided for one bill hanging device, and information on tags placed in a plurality of holders is set to 1. It can also be configured to be rewritten by a single input device.

  Next, a description will be given of an operation example in the case where billing is performed on site by the site control / monitoring apparatus according to this example. FIG. 4 is an explanatory diagram showing the cooperation with the central operation room when tagging is performed on site for plant equipment that performs operation restrictions for inspection, repair, and the like.

  First, the site operator 22 attaches the tag 13 with the wireless IC tag 31 in which the operation restriction information such as the operation restriction contents and the period of the target plant equipment is written to the tag device related to the plant equipment installed on the site. Place in the holder of the device 14. In this example, the act of placing a bill in the holder of the bill hanging device 14 corresponds to “filing”. Next, the IC tag reader 41 of the tagging device 14 reads the information of the wireless IC tag 31 of the tag 13 by wireless communication means and stores it in the tag information storage means 44 of the tagging device 14, and also by the transmission processing means 45. The data is transmitted to the control device 11 via the network 17. The control device 11 accumulates the operation restriction information of the device in the tag information management database 15, and performs system restrictions such as setting a billing state for the device and prohibiting the control operation from the screen. Further, the fact that the billing is set for the device is displayed on the billing display screen of the input / output device 12. Further, a message notifying that the billing has been set is automatically displayed on the screen of the input / output device, or the voice output device 18 is notified that the billing has been set, and the billing is set from the speaker 19. You may make a voice report.

  Further, when releasing the tagging, the site operator 22 takes out the tag 13 from the holder of the tagging device 14 at the site. As a result, the IC tag reader 41 of the tagging apparatus 14 recognizes that the tag has been removed, deletes the information from the tag information storage means 44 by the tag information management processing means 43, and releases the tagging by the transmission processing means 45. The request is transmitted to the control device 11. The control device 11 deletes the operation restriction information of the device from the tag information management database 15, cancels the tagging state of the device, and releases system restrictions such as prohibition of control operation from the screen. Thereby, control operation from the screen of the plant equipment becomes possible. Also, the tag display of the device on the tag display screen of the input / output device 12 is canceled. In addition, a message notifying that the tagging has been released is automatically displayed on the screen of the input / output device, or the voice output device 18 is notified that the tagging has been released, and the billing release setting is made from the speaker 19. You may be notified by voice.

  As a result, the on-site operator can automatically set or cancel the billing on the system in the control device by installing or removing the bill from the billing device at the site. As a result, it is no longer necessary for the operator in the field to contact the operator in the central control room, and the operator in the central control room recognizes the status of billing setting and release, etc. by displaying the screen of the input / output device and voice notification. And can be confirmed.

  Furthermore, since the operation restriction information transmitted from the billing device 14 is accumulated in the tag information management database 15, the bill remains on the site even if the control device 11 satisfies the billing deadline or the removal condition. Can be determined. When the control device 11 detects a removal omission such as a billing deadline exceeding, it can output a message notifying the display device 12 of the omission of the tag removal. Further, by sending a notice of removal leakage via the network 17 to the tagging device 14 on the site where the removal leakage tag is placed from the control device 11, the tag of the billing device 14 is placed. It is also possible to display a message notifying the omission of removal of the tag on the display device 48 at the place where the card is placed.

  In this way, in the present invention, it is possible to automatically recognize the operator of the central operation room by the tagging operation at the site, when the plant operator is doing what with which plant equipment, Incorrect operation and output can be prevented, and the safety of device operation can be further improved.

  Next, an example of a method for managing and operating tag information to be written on a tag to which the wireless IC tag of this example is attached will be further described. FIG. 5 is an explanatory diagram showing a tag information management method and operation method according to this example.

  First, a tag information management method in this example will be described. In this example, information to be written to the IC tag is managed by the tag information management device 16 connected to the control device 11 via the network 17, and the process of writing information to the wireless IC tag added to the tag is performed by the tag information management device. This is implemented by 16 tag information updating means 61. Note that the tag information management device 16 has a function of performing tag information update, data management of a tag information management database, and the like on a computer such as a personal computer equipped with a wireless IC tag information read / write means. . Tag information managed by the tag information management device 16 is stored in a tag information management database 15 connected via the network 17. The tag information management database 15 includes tag information management data 71, a tag information code table 72, and bill tag information storage data 73. The tag information management data 71 defines information to be written to the wireless IC tag attached to the tag, and assigns an identification number to the wireless IC tag, and defines data such as operation restriction information using the identification number as a key. is there. The tag information code table 72 is a table in which the content of tag information defined in the tag information management data 71 is coded and the content of the data corresponding to the code is defined. In the tag information management data 71, a code corresponding to each data item is defined. This is because the data is coded and managed in order to reduce the amount of data written to the wireless IC tag. The tagging tag information storage data 73 is information in which the control device 11 stores the information on the tagging wireless IC tag received from the tagging device 14 in the field corresponding to the arrangement position of each tagging device. This is for managing the actual billing state.

  Next, a tag information operation method in this example will be described. First, the field operator places the tag 13 related to the target plant device in the tag information management device 16 and reads the information written in the wireless IC tag using the tag information update means 61. Based on the read information, information such as the content of the work to be performed, the operation restriction period, and the operation restriction content is edited, and a predetermined tag No. in the tag information management data 71 is edited. Is rewritten ((a) of FIG. 5). Next, the tag information update unit 61 writes the updated data to the wireless IC tag 31 of the tag 13 ((b) of FIG. 5).

  The site operator brings the bill 13 with the updated data to the site ((c) in FIG. 5), and places it in the holder of the tagging device 14 on the site. Then, the IC tag reader 41 of the tagging device 14 reads out the tag information and stores it in the tag information storage means 44 ((d) in FIG. 5), and transmits it to the control device 11 via the network 17 for the tag information management database. The data is stored in the 15 bill tag information storage data 73 ((e) of FIG. 5). The information stored in the tag information storage unit 44 is displayed on the display device of the tagging device 14 at the site. When the site operator refers to the displayed information and determines that addition or change is necessary, the site operator adds or changes tag information with the input device 49 ((f) in FIG. 5). The contents changed at the site are stored in the tag information storage unit 44 of the tagging device 14, transmitted to the control device 11, and stored in the tagging tag information storage data 73 of the tag information management database 15. Thereby, the information changed in the field is reflected also in the tag information management database 15, and unified management of information can be performed.

  Next, a configuration example of each data in the tag information management database 15 will be described.

  FIG. 6 shows an example of the data structure of the tag information management data 71. The tag information management data 71 includes a tag number, which is an identification number assigned to the wireless IC tag attached to the tag. 711 as a key and tag No. For each 711, work details such as a device name 712, work content 713, work period 714, work manager 715, and operation restriction information such as an operation restriction content 716, an operation restriction period 717, and supplementary information 718 are defined. Information such as the device name and work contents is coded, and the corresponding code is defined as the data defined in the tag information management data 71. Data defined here is written in the wireless IC tag as tag information.

  FIG. 7 shows an example of the data configuration of the tag information code table 72. In this example, the tag information code table 72 is defined as being divided into a plurality of tables. However, these data may be defined as one database. 7A shows an example 721 of the equipment code for identifying the plant equipment, FIG. 7B shows an example 722 of the work code indicating the work content, and FIG. 7C shows the operation. A definition example 723 of the operation restriction code indicating the restriction content and FIG. 7D show a definition example 724 of the work supervisor code indicating the work supervisor. In this way, work information and operation restriction information to be written on the wireless IC tag attached to the tag are defined as codes, and tag information to be written on the IC tag is managed by the code.

  FIG. 8 shows an example of the data structure of the bill tag information storage data 73. The tagging tag information storage data 73 is data for managing information on the tags placed in all the tagging devices installed at the site, and the tagging device No. which is an identification number assigned to the tagging device. 731 and the billing position 732. The bill hanging position 732 indicates the position of the holder provided in the bill hanging apparatus, and the bill hanging position is represented as 1, 2, 3,... According to the number of holders. When a tag is placed on the tagging device at the site, information read from the placed tag is transmitted from the tagging device to the control device 11, and the control device 11 receives the corresponding billing device number. 731, data is stored in the billing position 732. Here, a tag number for identifying the IC tag of the tag placed is shown. 733 and the billing start date and time 734 are stored. Tag No. If the tag information is known, the tag information written in the tag can be understood by referring to the tag information management data 71. Can be identified only by the date and time when it was detected that the tag was placed.

  Further, among the tag information written in the IC tag, data that can be changed and data that cannot be changed are defined, and information that can be changed from the input device 49 of the tagging device 14 by the field operator can be limited. . For example, if the operation restriction content cannot be changed but the operation restriction period and supplementary information can be changed, or if the field operator changes data from the input device 49, the billing device 14 sends the changed data to the control device 11. The information is updated when the control device 11 stores the information in the tagging tag information storage data 73. FIG. 8 shows an example in which an operation restriction period change column 735 and a supplemental information column 736 are provided as changeable data items so that information changed on site can be stored.

  In this example, the tag hanging device in the field, have defined how pre tags which plant equipment is located, if the tags wrong plant equipment is placed, ticketing display tags hanging device It is possible to notify the field operator by displaying a message notifying the erroneous posting. In large-scale plants such as industrial plants and power plants, there are many similar devices, and there are cases where multiple systems of similar equipment configurations are in parallel, so the target equipment may not be easily identified. is there. For this reason, there is a case where a tag is mistakenly placed on the work target device. In this example, the tag information of the tag on which the billing device is placed can be read, so that an erroneous posting of the tag can be detected, an erroneous operation can be prevented, and the work can be performed safely.

  Further, in this example, an example is described in which tags are managed for each plant device, but in that case, the number of tags becomes large and management becomes complicated. Therefore, it is possible to manage the tag for each work content, not for each device. In that case, the tag information may be recorded in advance with work contents and operation restriction contents, and only information such as the target device and work period may be updated before the tag is actually used.
