Description

  The present invention relates to a system operation panel for monitoring, monitoring, operating, or controlling the operating state of a system including equipment installed in a production plant, a production line, or the like.

  For example, production plants, production lines, production equipment, indoor facilities, etc. (hereinafter also referred to as “plants”) are many and various, such as driving devices such as motors, measuring instruments including passive devices and sensors, etc. It is often configured as a system with various equipment. Many of these equipments are operated individually or in cooperation to operate and operate a production plant or the like so as to achieve a predetermined purpose such as manufacturing a product. A system operation panel as shown in FIG. 17 is often used to monitor, monitor, operate, or control at least a part of these many equipments.

  As shown in FIG. 17, the system operation panel has many and various display devices such as analog meters and digital meters, setting devices, open / close levers, analog setting levers, push buttons, ON / OFF on the panel surface. It has operation devices such as changeover switches, toggle switches, slide switches, rotary switches, lever switches, etc., and the display device displays predetermined signals such as measurement signals received from equipment, and the operation devices are operators. A predetermined signal generated according to the operation of (user) is transmitted to the corresponding equipment. Therefore, an operator operating this equipment monitors and monitors the operating state of each equipment and the status of the manufacturing plant by recognizing a predetermined signal displayed on the display equipment, and operates the operating equipment. Each facility device can be operated and controlled by generating and outputting a predetermined signal.

  Such a system operation panel is, for example, machining a part to which an operation device or a display device (hereinafter simply referred to as “device”) is attached, or a signal line connected to each facility device and each device. Are connected by soldering or wiring. That is, for example, a through hole is formed in the front panel of the system operation panel so that each device can be attached, and each device is arranged in the through hole. And it is necessary to connect a large number of signal lines so that each arranged device can be correctly connected to the equipment device. Therefore, in general, the system operation panel is usually customized and manufactured in accordance with the configuration and arrangement of equipment such as each plant, and is not only very expensive, but once manufactured, It is difficult to change the arrangement position or replace the device. Therefore, it is necessary to fully study the operability of the system operation panel before the production so that there is no such change after the production.

  However, with regard to the operability of the system operation panel, conventionally, it has been possible only to examine the design drawings, etc., and the operator must operate the system operation panel that is actually manufactured and assembled. It is difficult to feel the operability of the board. Therefore, it is often the case that the optimum arrangement position of each device is found after it is actually manufactured and used. As a result, the operator is forced to use a system operation panel that is difficult to use, and additional costs, labor, and time are often required to change the layout of the system operation panel.

  On the other hand, with the recent IT (information technology), a monitoring operation device simulating a system operation panel is created by HMI (Human Machine Interface) using an information processing device such as a computer and a display device such as a monitor. In some cases. In this case, the computer collectively processes signals from various equipment and signals to the equipment. The computer displays a signal from the facility device on the monitor in a manner similar to a display device, or outputs a predetermined signal to each facility device in accordance with an operator's operation on an input device such as a mouse, a keyboard, or a touch panel. .

  However, the operational feeling of operating devices such as setting devices, open / close levers, analog setting levers, push buttons, ON / OFF switch, toggle switch, slide switch, rotary switch, lever switch etc. This is completely different from the operation feeling of touch panels. Further, in the case of an operating device that requires a delicate operation of the operator, such as an analog setting lever or a rotary switch, the operator often controls the delicate operation by the operational feeling of each operating device. It is difficult to replace such a switch with a mouse or the like. Some operators operate a plurality of operating devices at the same time, and it is difficult to realize such an operation with a mouse, a touch panel, or the like. Moreover, since the display area of the display device is limited on the monitor, it is difficult to display a plurality of devices so that they can be viewed simultaneously. Therefore, all system operation panels cannot be changed to HMI or the like.

  Although it is a system operation panel that is difficult to completely replace even with HMI as described above, an operation function reflecting the image of actual equipment is built for offline offline debugging and operator training prior to plant operation. It is also desirable to do. However, as described above, it is difficult to easily construct an operation monitoring panel.

  Therefore, the present invention has been made in view of the above problems, and the present invention facilitates a system operation panel for centrally operating a system composed of a plurality of equipment devices such as a manufacturing plant. A first object of the present invention is to provide a system operation panel that can be configured and can easily change the arrangement of each device even after production. The second object of the present invention is to provide a system operation panel having a flexible arrangement configuration setting function that can be used for studying the operability of the system operation panel prior to production of the system operation panel. To do.

In order to solve the above problems, according to an aspect of the present invention, in a system configured with a plurality of equipment, the system is monitored and monitored by transmitting and receiving predetermined signals connected to the plurality of equipment. A system operation panel for operation or control, each having a device-side connector of the same shape for transmitting the predetermined signal, and a plurality of devices for displaying or generating the predetermined signal, and the device-side connector A panel having a plurality of panel-side connectors connectable to the connector, a connector specifying unit for specifying the panel-side connector connected to the device-side connector, and a device connected to the panel-side connector by the device-side connector, A device information acquisition unit that acquires device information and a panel specified by the connector specification unit based on the device information acquired by the device information acquisition unit. A correspondence determining unit that determines the correspondence between the side connector and the external equipment, and at least a signal input from the equipment based on the correspondence determined by the correspondence determining unit. Connection switching that outputs to the equipment via the panel-side connector corresponding to the equipment or outputs the signal transmitted from the equipment to the panel-side connector to the equipment corresponding to the panel-side connector possess a part, and each device has a storage unit for device information is recorded, the device information acquisition unit and acquires the device information without using the apparatus side connector from the storage unit A system operation panel is provided.

  According to this configuration, each of the plurality of devices has a device-side connector having the same shape, and thus can be arranged at an arbitrary position on the panel where the panel-side connector is formed. When the device is arranged at a desired position on the front surface of the panel, the device-side connector of the device is connected to one panel-side connector. Thereafter, the connector identifying unit can identify the panel-side connector to which the device-side connector is connected, and the device information obtaining unit can obtain device information about the device from the device connected to the panel-side connector. it can. In addition, as for this apparatus information, it is desirable to include the identification information which can specify an apparatus at least, for example. Then, the correspondence relationship determining unit may determine the correspondence relationship between the panel-side connector and the facility device, for example, indicating which facility device the panel-side connector is associated with, based on the device information. it can. As a result, based on this correspondence, the connection switching unit outputs at least a signal input from the equipment to the equipment via the panel-side connector corresponding to the equipment, or the equipment on the panel-side connector. Can be output to the equipment corresponding to the panel-side connector. Therefore, for example, if each device is arranged, the correspondence between the device and the equipment is automatically determined, and each signal is transmitted based on the correspondence. Therefore, wiring and connection work for each device can be omitted. Moreover, even if it is going to change the position of the apparatus once arrange | positioned, the above correlations are performed automatically. Accordingly, the layout can be easily changed while reducing the labor.

Moreover, according to such a structure, an apparatus information acquisition part acquires apparatus information from the memory | storage part of each apparatus, without going through an apparatus side connector. Accordingly, the types of signals transmitted by the panel side connector can be reduced. In addition, since the panel side connector is formed in the same shape, it is desirable to be able to transmit various signals such as digital input, digital output, analog input, and analog output. While these predetermined signals can be used as appropriate even after the system operation panel is manufactured, the device information needs to be transmitted when each device is arranged or when the position is changed. Therefore, by acquiring this device information through another route without passing through the same connector as other signals, the number of terminals in the connector can be reduced and the connector can be downsized. Further, it is not necessary to design a signal path so that the device information passes through the connector, and the device itself can be easily designed.

The storage unit included in the device may be an IC tag in which the device information is recorded, and the device information acquisition unit may acquire the device information wirelessly transmitted from the IC tag.
According to such a configuration, each device has an IC tag, and the device information acquisition unit can acquire device information wirelessly transmitted from the IC tag. By acquiring the device information wirelessly in this way, it is not necessary to provide a separate wiring for the device information between the device and the panel, and manufacturing is easy. Moreover, since it is non-contact communication transmitted by radio | wireless, malfunctions, such as being unable to acquire apparatus information by the poor contact in the connection part between terminals, etc., can be reduced, for example.

  The IC tag may be an active tag that wirelessly transmits the device information when the device-side connector is connected to the panel-side connector.

In addition, the storage unit included in the device is a one-dimensional or two-dimensional code that is arranged on a surface facing the panel and in which the device information is recorded. A hole may be formed, and the device information acquisition unit may acquire the device information by reading the code through the through hole by a code reading unit disposed on the back side of the panel.
According to this configuration, each device has a code, and the code reading means can read the device information recorded in the code through the through hole formed in the panel. Then, the device information acquisition unit can acquire the device information read by the code reading means. In addition, there is no need to provide a separate wiring for the device information between the device and the panel, and it is easy to manufacture and the device information cannot be acquired due to poor contact at the connection between terminals. Can be reduced.

The connector may further include a moving unit that moves the code reading unit, and the connector specifying unit may specify the panel-side connector based on position information of the code reading unit moved by the moving unit.
According to this configuration, the code reading unit can be moved by the moving unit. And the connector specific | specification part can specify a panel side connector based on the positional information on the code reading means. When the code reading unit reads the code, the device information acquisition unit can acquire the device information of the device connected to the panel-side connector.

  As described above, according to the present invention, it is possible to easily configure a system operation panel that can easily change the arrangement of each device even after production. As a result, the system operation panel can be used as a system operation panel having a flexible arrangement configuration setting function that can be used for studying the operability of the system operation panel prior to production of the actual system operation panel.

  Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  In order to operate a plant or the like, the system operation panel according to each embodiment of the present invention collectively monitors, monitors, operates, or controls at least some of the plurality of facility devices arranged in the plant or the like. A plurality of devices are arranged on this system operation panel. Each device is roughly classified into, for example, a display device and an operation device. The display device (monitoring / monitoring component) displays, for example, a signal (hereinafter also referred to as “input signal”) for monitoring the facility device, which represents the operation state or measurement value of the facility device, and the input signal. A predetermined display corresponding to is performed. Examples of the display device include an analog display such as an analog meter and an analog monitor, a digital display such as a digital meter and a digital monitor, and a lamp display. The operation device (operation component) is a predetermined signal (hereinafter also referred to as an “output signal”) for operating each facility device in accordance with a user operation, and is also referred to as an “input / output signal” together with the input signal. ) Is generated and output. Examples of the operation device include a setting device, an open / close lever, an analog setting lever, a push button, various switches such as an ON / OFF switch, a toggle switch, a slide switch, a rotary switch, and a lever switch. In a general system operation panel, wiring for directly connecting such equipment and each facility equipment is required for each signal.

The panel 200 is disposed on the front surface of the system operation panel 10, is formed so that a plurality of devices 100 can be connected, and is connected to the connection control unit 300. In FIG. 1, the panel 200 is illustrated in a planar shape, but it is needless to say that the shape of the panel 200 is not limited to a planar shape and may be a curved surface. And the transmission path of the input / output signal of each apparatus 100 is controlled by the connection control unit 300. Each configuration of the device 100, the panel 200, and the connection control unit 300 will be described.

(Device 100)
FIG. 2 is an explanatory diagram for explaining an example of the device 100 included in the system operation panel according to the present embodiment. FIG. 3 is an explanatory diagram for explaining a device-side connector that each device 100 has for transmitting input / output signals, power, and the like to / from external devices / parts such as equipment.

  As shown in FIG. 2, examples of the device 100 include an analog setting lever 100A, an analog meter 100B, a push button 100C, and a digital meter 100D. However, the device 100 is not limited to these examples.

  As shown in FIG. 3, these devices 100 include a device-side connector 110 and an active tag 120 on the surface (back surface) facing the panel 200.

  The device-side connector 110 has a shape protruding from the back surface of the device 100 and is formed in the same shape as all the devices 100. The device-side connector 110 is formed with a plurality of terminals capable of transmitting input / output signals. The terminal Di_0 is a terminal for confirming insertion of the device 100. When the device 100 is disposed on the panel 200 and the device-side connector 110 is connected to a panel-side connector 210 described later, the device 100 is disposed. It plays a role to notify that. The terminal PWR is composed of two plus / minus terminals, and supplies power to the device 100 and the active tag 120 from the panel 200. The terminals Di_1 and Di_2 are each composed of two plus / minus terminals, and transmit digital input signals from the panel 200 to the device 100. The terminals Do_1 and Do_2 are each composed of two plus / minus terminals, and transmit a digital output signal from the device 100 to the panel 200. The terminals Ai_1 and Ai_2 are each composed of two plus / minus terminals, and transmit an analog input signal from the panel 200 to the device 100. Terminals Ao_1 and Ao_2 are each composed of two plus / minus terminals, and transmit an analog output signal from the device 100 to the panel 200.

  That is, the device-side connector 110 has a digital input / output line and an analog input / output line. Therefore, the same device-side connector 110 can be used for both the analog device 100 and the digital device 100. In addition, since each line includes a plurality of lines, a plurality of input signals and output signals can be transmitted.

  Here, although the connector shape is shown as a quadrangular prism type, this connector shape may be any shape such as a cylindrical side, a triangular prism type, and a polygonal column type. Also, the number of terminals of input / output lines and the number of lines are not limited to the above example.

  The active tag 120 is an example of a storage unit and an IC tag, in which device information is recorded. The active tag 120 is connected to the terminal PWR. When power is supplied to the terminal PWR, the active tag 120 wirelessly transmits device information. That is, the active tag 120 transmits device information when the device 100 is placed on the panel 200. Note that, from the viewpoint of association with a target device to be described later, it is desirable that the device information according to the present embodiment is not output after a predetermined period has elapsed since the power was supplied. The “device information” is information regarding each device 100 and preferably includes identification information for identifying each device 100. Here, an active tag 120 included in each device 100 is given a unique identification number for each device 100, and the tag identification number serves as identification information for each device.

(Panel 200)
Next, the panel 200 will be described with reference to FIG.
FIG. 4 is an explanatory diagram for explaining a panel included in the system operation panel according to the present embodiment.

  The panel 200 is an example of a pedestal portion, and may be formed in a flat plate shape of about 1 m × 1 m and various other shapes, for example. A plurality of panel-side connectors (pedestal receiving portions) 210 are formed on the front surface of the panel 200 facing the operator. For example, as shown in FIG. 4, the panel-side connector 210 is desirably arranged like a grid of equal intervals of about 50 mm, but the arrangement position of the panel-side connector 210 is limited to this example. It is not a thing.

  Each panel-side connector 210 is formed in a shape that can be connected to the device-side connector 110 included in the device 100. Here, the case where the device-side connector 110 is formed in a quadrangular prism shape is shown, so that the panel-side connector 210 is an example in which the square-column-shaped device-side connector 110 can be inserted and formed as a hole having a quadrangular cross section. Show. The device-side connector 110 and the panel-side connector 210 may be formed in any shape as long as they can be engaged with each other. For example, it goes without saying that the panel-side connector 210 may have a shape protruding from the panel 200 and the device-side connector 110 may have a shape recessed from the back surface of the device 100.

  Each panel-side connector 210 is provided with terminals that can be connected to a plurality of terminals of the device-side connector 110. Since each terminal corresponds to each terminal of the device-side connector 110, detailed description thereof is omitted here. Each terminal is connected to the terminal block 220 and is connected to the connection control unit 300 via the terminal block 220.

  Thus, by forming the device-side connectors 110 of all the devices 100 in the same shape and forming a plurality of panel-side connectors 210 to which the device-side connectors 110 can be connected on the panel 200, the devices 100 and 200 It is possible to standardize the shape and size of the attachment part and the standard such as the fixing method and signal contact, and the device 100 can be arranged at an arbitrary position. Note that the number of terminals of the device-side connector 110 and the panel-side connector 210 is not limited to the above example, and can be increased or decreased.

(Connection control unit 300)
The connection control unit 300 will be described with reference to FIG. 1 again. The connection control unit 300 can automatically assign an input / output address (for example, an I / O address, a network address, etc.) to a predetermined signal generated or displayed on the system operation panel 10. As shown in FIG. 1, the connection control unit 300 includes input / output units 310 and 320, a connection position specifying unit 311, a wireless communication unit 312, a device information acquisition unit 313, a correspondence relationship determination unit 314, a tag A table storage unit 315, an I / O table storage unit 316, a correspondence table storage unit 321, and a connection switching unit 322 are included.

  The input / output unit 310 is an interface for input / output signals to the panel 200 and is connected to the terminal block 220.

  The connection position specifying unit 311 is an example of a connector specifying unit, and when the device 100 is connected and the terminal Di_0 of the panel side connector 210 is energized through the terminal Di_0 of the device side connector 110, the device 100 is arranged. The position of the panel-side connector 210 is specified. At this time, as shown in FIG. 4, each panel-side connector 210 is also assigned an identification number, and the connection position specifying unit 311 specifies this identification number (an example of position information) to thereby identify the panel-side connector 210. May be specified. This identification result is output to the correspondence determining unit 314.

  On the other hand, as described above, when the device 100 is arranged on the panel 200, the active tag 120 of the device 100 receives power supply and wirelessly transmits device information. The wirelessly transmitted device information is received by the wireless communication unit 312. The wireless communication unit 312 is a reader / writer of the active tag 120 and reads received device information. Note that the wireless communication unit 312 does not have to have a writer function, but by having the writer function, the device information of the active tag 120 can be rewritten as necessary. In this case, the connection control unit 300 has a device information writing unit 317, and the wireless communication unit 312 is based on the writing information sent from the device information writing unit 317, and the device information of the active tag 120. Update. At this time, the device information writing unit 317 also rewrites the tag table recorded in the tag table storage unit 315 in the same manner as updating the device information.

  The device information acquisition unit 313 acquires the device information read by the wireless communication unit 312 and outputs it to the correspondence determination unit 314. That is, the device information acquisition unit 313 acquires device information from the device 100 connected to the panel-side connector 210 whose position is specified by the connection position specifying unit 311, and the correspondence determining unit 314 is the same device 100. The position information and the device information for are acquired at the same time or during a predetermined period.

  The correspondence determining unit 314 determines the correspondence between the device 100 and the facility device to be connected to the device 100 based on the device information and the position information regarding the same device 100. In other words, the correspondence relationship determination unit 314 associates the device 100 with the facility device. At this time, in addition to the device information and the position information, the correspondence determining unit 314 includes a tag table recorded in the tag table storage unit 315 and an I / O (Input / Output) stored in the I / O table storage unit 316. ) Create a correspondence table based on the table. Then, the correspondence determination unit 314 records the created correspondence table in the correspondence table storage unit 321. The creation of the correspondence table by the tag table, the I / O table, and the correspondence determination unit 314 will be described later.

  The input / output unit 320 is an example of a network communication unit, and is connected via the network 30 to the plant control unit 20 that controls equipment. In other words, the input / output unit 320 plays the role of an interface to the equipment. That is, the input / output unit 320 receives an input signal generated by the equipment and transmitted via the plant control unit 20 and outputs the input signal to the connection switching unit 322, while the panel 100 and the input / output unit 310 from each device 100. The output signal sequentially transmitted to is acquired from the connection switching unit 322 and output to the plant control unit 20 via the network. And the plant control part 20 will operate an installation apparatus based on this output signal. In the present embodiment, the equipment is controlled by the plant control unit 20. However, when the equipment is controlled without going through the plant control unit 20, the input / output unit 320 can be directly connected to the equipment. Connections such as “which output signal is output to which equipment (that is, which equipment is used for the operation)” and “which equipment 100 the output signal from which equipment is transmitted to” The relationship is determined by the correspondence table, and the connection switching unit 322 controls the connection relationship. The control of each input / output signal by the connection switching unit 322 will be described later together with the tag table and the like.

  Before describing the tag table, the I / O table, the correspondence relationship table, and the connection switching unit 322, an example of the plant control unit 20 will be described.

(Plant control unit 20)
The plant control device 20 is a control device that controls each equipment device included in a plant or the like, and includes an input / output unit 21, a plant control unit 22, and a variable table storage unit 23.

  The input / output unit 21 is connected to the system operation panel 10 via the network 30 and serves as an interface to the system operation panel 10 that transmits input / output signals.

  The plant control unit 22 is connected to the equipment and the input / output unit 21, controls the equipment based on an output signal sent from the system operation panel 10 via the input / output unit 21, and sends it from the equipment. The input signal is output to the system operation panel 10 via the input / output unit 21. At this time, each input / output signal is distinguished by a variable table stored in the variable table storage unit 23. This variable table will be described.

(Variable table)
FIG. 5 is an explanatory diagram for explaining the variable table.
As shown in FIG. 5, the variable table is information representing the correspondence between the variable name (that is, the signal name) of each input / output signal and the network address assigned to the signal. That is, for example, the network address “% MX.1.0.0” is assigned to the input / output signal used in the equipment device for starting line operation. The “network address” is identification information for distinguishing each input / output signal. The flow of each signal based on the variable table will be described as follows. That is, when the plant control unit 22 obtains an output signal from the system operation panel 10, the plant control unit 22 identifies a variable name based on the network address assigned to the output signal and the variable table, and uses the signal of the variable name. The equipment is controlled by outputting an output signal or a predetermined signal corresponding to the output signal to the equipment. On the other hand, when the plant control unit 22 acquires an input signal from each facility device, the plant control unit 22 assigns a network address corresponding to the facility device that generated the input signal to the input signal based on the variable table, and assigns the input signal to the system operation panel. 10 is output. The network address of the input signal can be directly included in the input signal by each equipment device. In this case, the input signal may be output to the system operation panel 10 without going through the plant control device.

(Tag table)
Next, the tag table recorded in the tag table storage unit 315 will be described with reference to FIG. FIG. 6 is an explanatory diagram for explaining the tag table.

  As shown in FIG. 6, the tag table represents a correspondence relationship between device information (for example, an identification number of the active tag 120 included in the device 100) and a network address assigned to an input / output signal of the device 100 having the device information. Information. That is, for example, among the input / output signals of the device 100 whose identification number of the active tag 120 is “TAG — 001”, the digital output signal (that is, the output signal transmitted through the terminal Do_1) has the network address “% MX.1. 0.0 "is assigned. When the plant control device 20 is created and the network address of the availability signal used in the plant control device 20 and the device 100 that generates or displays the input / output signal are determined, the tag table is determined. . Therefore, this tag table does not depend on the arrangement position of the device 100, and is changed when, for example, the control target is changed or the control method of the plant control device 20 is changed. Here, the case where the device information stored in the active tag 120 includes an identification number for specifying the device has been described, but the device information may include other information.

(I / O table)
Further, the I / O table recorded in the I / O table storage unit 316 will be described with reference to FIG. FIG. 7 is an explanatory diagram for explaining the I / O table.

  As described above, a network address is assigned to each input / output signal. Separately, an I / O address is assigned to each terminal of each panel-side connector 210 of the panel 200 of the system operation panel 10. . The “I / O address” is identification information for distinguishing the signal line of each signal transmitted from the system operation panel, and different values are assigned to all terminals of the panel side connector 210. That is, as shown in FIG. 7, the I / O address “% 1A.Di.0.0” is assigned to the terminal Di_0 (terminal number 1A-1) among the terminals of the panel-side connector 210 having the identification number 1A. The terminal Di_1 (terminal number 1A-2) is assigned the I / O address “% 1A.Di.0.1”. Such an I / O table is determined when the panel 200 or the like is created. Therefore, the I / O table does not depend on the arrangement position of the device 100 and is hardly changed except when the panel 200 itself is changed, for example.

(Creation of correspondence table by correspondence determination unit 314)
Next, creation of a correspondence table (input / output management database) by the correspondence determining unit 314 will be described.
As described above, the correspondence determination unit 314 determines the correspondence between the device 100 and the facility device based on the device information and the position information regarding the same device 100 and using the tag table and the I / O table. Determine and create a correspondence table. At this time, the correspondence relationship determination unit 314 creates a correspondence relationship table as follows.

  That is, the correspondence determining unit 314 first sets each device 100 as shown in FIG. 8 based on the position information (for example, the identification number of the panel-side connector 210) and the device information (for example, the identification number of the active tag 120). A first correspondence relationship table is created that associates the panel-side connector 210 to which the device 100 is connected. At this time, the position information is determined when the device-side connector 110 is connected to the panel-side connector 210, and the device information is acquired by the device information acquisition unit 313 within a predetermined period from that time. Therefore, the correspondence determining unit 314 can create the first correspondence table by associating the position information acquired within the predetermined period with the device information. In the first correspondence table shown in FIG. 8, for example, the device 100 having the active tag 120 with the identification number “TAG — 001” and the panel connector 210 having the identification number “1A” are associated with each other. Show.

  Next, the correspondence determining unit 314 creates a second correspondence table as shown in FIG. 9 based on the first correspondence table, the tag table, and the I / O table. More specifically, the correspondence determining unit 314 first uses the identification number (position information) of the panel-side connector 210 and the I / O table in the first correspondence table, and each panel-side connector 210 has Specify the I / O address of the terminal. Next, the correspondence determining unit 314 uses the identification number (device information) of the active tag 120 associated with the panel-side connector 210 and the tag table in the first correspondence table, and the input / output used by the device 100. Identify the network address of the signal. Then, the correspondence determining unit 314 associates the identified I / O address with the network address and creates a second correspondence table as shown in FIG. A more specific example will be described. For example, in the first correspondence table shown in FIG. 8, the device 100 having the active tag 120 with the identification number “TAG — 001” is associated with the panel-side connector 210 having the identification number “1A”. The determining unit 314 specifies the I / O address “% 1A.DI.0.0”, “% 1A.DI.0.1”, and the like of the panel side connector 210 based on the I / O table. Then, the correspondence determination unit 314 identifies the network address “% MX1.0.0 (Di_1)” of the input / output signal used by the device 100 based on the tag table. The network address “% MX1.0.0 (Di_1)” is assigned to the corresponding I / O address “% 1A.DI.0.1”. As a result, the correspondence relationship determination unit 314 creates a second correspondence relationship table as shown in FIG. 9, and the correspondence relationship table storage unit 321 also refers to this second correspondence relationship table (hereinafter simply referred to as “correspondence relationship table”). .) Is recorded.

(Control of input / output signals by the connection switching unit 322)
With the correspondence relationship table created in this way, each device 100 and each facility device are associated with each other, and input / output signals are transmitted between them. As described above, the transmission of this input / output signal is controlled by the connection switching unit 322. The control of input / output signals by the connection switching unit 322 will be described as follows.

  For example, when a certain equipment generates an input signal, the network address is attached to the input signal by the equipment itself or the plant control device 20 and is transmitted to the connection switching unit 322 via the network 30 and the input / output unit 320. Is done. The connection switching unit 322 specifies an I / O address based on the network address of this input signal and the correspondence table shown in FIG. Then, the connection switching unit 322 outputs an input signal to a terminal having a corresponding I / O address. Accordingly, the input signal is output to the device 100 associated with the facility device that generated the input signal. On the other hand, for example, when a certain device 100 generates an output signal, the output signal is transmitted to the connection switching unit 322 via the terminal of the panel-side connector 210 to which one I / O address is allocated. The connection switching unit 322 specifies a network address based on the I / O address of the terminal to which the output signal is transmitted and the correspondence table shown in FIG. Then, the connection switching unit 322 assigns the corresponding network address to the output signal and outputs it to the plant control device 20 via the network 30. Therefore, the plant control apparatus 20 can determine by referring to the network address as to which equipment the output signal is related to. Therefore, the output signal can be output to the equipment associated with the equipment 100 that generated the output signal or used for the operation of the equipment.

<Operation of System Operation Panel 10 According to First Embodiment>
Next, the operation of the system operation panel 10 according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 10 is an explanatory diagram for explaining the operation of the system operation panel according to the present embodiment during production or layout change. 11 and 12 are explanatory diagrams for explaining the operation of the system operation panel according to the present embodiment after production.

(Operation during production or layout change)
When the system operation panel 10 is being manufactured or the layout is changed, as shown in FIG. 10, first, in step S <b> 101, the device 100 is placed on the panel 200. Then, it progresses to step S103 and the apparatus side connector 110 of the apparatus 100 is connected to the panel side connector 210 of the panel 200, and each terminal, especially the confirmation terminal Di_0 and the power supply terminal PWR are energized. Next, the process proceeds to step S105.

  In step S105, the connection position specifying unit 311 specifies the panel-side connector 210 (position) to which the confirmation terminal Di_0 is energized, and outputs position information. In step S107, the device information acquisition unit 313 acquires the device information transmitted from the active tag 120 to which power is supplied via the wireless communication unit 312. Note that step S105 and step S107 may be processed simultaneously, or step S105 may be processed after step S107 is processed. After step S107 (or step S105), the process proceeds to step S109.

  In step S <b> 109, the correspondence relationship determination unit 314 creates a first correspondence relationship table as shown in FIG. 8 based on the position information and device information, and records it in the correspondence table storage unit 321. Then, the process proceeds to step S111.

  In step S111, the correspondence determining unit 314 performs the processing shown in FIG. 9 based on the first correspondence table, the tag table as shown in FIG. 6 and the I / O table as shown in FIG. A second correspondence relationship table as shown is created and recorded in the correspondence relationship table storage unit 321. Then, the process proceeds to step S113.

  In step S <b> 113, the correspondence relationship determination unit 314 confirms whether or not all the devices 100 to be arranged on the panel 200 have been arranged. This confirmation is performed, for example, by the correspondence relationship determination unit 314 confirming whether or not all network addresses recorded in the tag table are associated with the I / O addresses in the second correspondence relationship table. Also good. The correspondence determining unit 314 can also determine that all the devices 100 have been arranged according to the user's operation, and when a state in which no new device 100 is arranged continues for a predetermined period, It is also possible to automatically determine that all the devices 100 have been arranged. And when not all the apparatuses 100 are arrange | positioned, the process after step S101 is performed again. In addition, when all the devices 100 are arranged, the production of the system operation panel 10 or the layout change operation ends. With such an operation, when the device 100 is arranged on the panel 200, the connection control unit 300 can associate the device 100 with the facility device. This association is performed every time the arrangement position of the device 100 is changed.

(Operation when transmitting input signal after production)
In the system operation panel 10 manufactured as described above, the second correspondence table is stored in the correspondence table storage unit 321. After production, the transmission path of each input / output signal is determined based on the correspondence table. As an operation of the system operation panel 10 when transmitting an input / output signal, an operation of the system operation panel 10 when an input signal is input from the equipment will be described with reference to FIG.

  First, in step S201, the connection switching unit 322 generates an input signal generated by one facility device and added with a network address by the facility device or the plant control device 20 via the plant control device 20 / network 30 or the like. get. Then, step S203 is processed.

  In step S203, the connection switching unit 322 confirms the network address added to the input signal. In step S205, the connection switching unit 322 further checks the correspondence table (second correspondence table) recorded in the correspondence table storage unit 321. Then, the process proceeds to step S207.

  In step S207, the connection switching unit 322 specifies an I / O address corresponding to the network address confirmed in step S203 based on the correspondence table. Then, the process proceeds to step S209.

  In step S209, the connection switching unit 322 outputs an input signal to the terminal of the panel side connector 210 corresponding to the I / O address specified in step S207, and the operation ends. By such an operation, an input signal generated by one facility device can be transmitted to the device 100 corresponding to the facility device.

(Operation when transmitting the output signal after production)
Next, as an operation of the system operation panel 10 when transmitting an input / output signal, an operation of the system operation panel 10 when an output signal is output to the equipment will be described with reference to FIG.

  First, in step S301, one device 100 generates an output signal in accordance with a user operation or the like. Then, the output signal is sequentially transmitted from the device-side connector 110 to the connection switching unit 322 via the panel-side connector 210, the terminal block 220, and the input / output unit 310. Then, step S303 is processed.

  In step S303, the connection switching unit 322 confirms the I / O address of the terminal of the device-side connector 110 to which the output signal has been transmitted. In step S305, the connection switching unit 322 further checks the correspondence table (second correspondence table) recorded in the correspondence table storage unit 321. Then, the process proceeds to step S307.

  In step S307, the connection switching unit 322 specifies a network address corresponding to the I / O address confirmed in step S303 based on the correspondence table. Then, the process proceeds to step S309.

  In step S309, the connection switching unit 322 adds the network address specified in step S307 to the output signal. And it progresses to step S311 and the connection switch part 322 outputs this output signal to the plant control apparatus 20 via the network 30, and complete | finishes operation | movement. On the other hand, the plant control device 20 that has received this output signal identifies the equipment that uses the output signal based on the added network address and variable table, and transmits the output signal to the equipment. The equipment can be controlled in accordance with the output signal.

  It should be noted that the operation when transmitting the input signal or the output signal after production described here is preferably performed constantly during the operation of the system operation panel 10. Further, in the above description, as an operation after the manufacture, the case where the connection switching unit 322 confirms the correspondence table when the input signal or the output signal is acquired is described. However, the connection switching unit 322 performs the correspondence table. The timing for confirming is not limited to this example. For example, the connection switching unit 322 constantly checks or holds the correspondence table, constantly monitors the transmitted input signal or output signal, and inputs or outputs the input signal or output signal to the corresponding I / O address or network address. May be transmitted.

<Example of effects by system operation panel 10 according to the first embodiment>
The system operation panel 10 according to the first embodiment of the present invention has been described above.
According to the system operation panel 10, the device 100 can be arranged at a desired position on the panel 200 by forming the device-side connector 110 in the same shape and forming a plurality of panel-side connectors 210 on the panel 200. . When the device 100 is arranged, the system operation panel 10 can automatically assign an input / output address to each input / output signal. That is, the system operation panel 10 includes the device 100 and the device 100. Can be automatically associated with equipment that communicates input / output signals. Accordingly, it is possible to omit connection and address assignment processing when the device 100 is arranged or changed. Therefore, the system operation panel 10 can be easily created and the layout can be easily changed even after production. As a result, according to the system operation panel 10, for example, the system operation panel 10 is temporarily manufactured in the production stage of the system operation panel 10, and the operability is verified by the operator actually using the system operation panel 10. After that, it is easy to change the arrangement position of the device 100. Therefore, the production cost of the system operation panel 10 can be reduced.

<Modified Example of System Operation Panel 10 According to First Embodiment>
In the system operation panel 10 according to the first embodiment, every time the device 100 is arranged, the device information acquisition unit 313 acquires the device information, and the connection position specifying unit 311 specifies the connection position. Thus, the case where the correspondence determining unit 314 determines the correspondence with the device 100 has been described. However, the present invention is not limited to this example. That is, for example, after all the devices 100 are arranged, it is also possible to determine the correspondence relationship with respect to those devices 100. In this case, for example, when all the devices 100 are arranged, the connection position specifying unit 311 may sequentially supply power to the power supply terminals PWR of the panel-side connectors 210. Then, device information is transmitted from the active tag 120 of each device 100 in the order in which power is supplied. Therefore, the connection position specifying unit 311 can specify the panel-side connector 210 based on the order in which the power is supplied, and the device information acquiring unit 313 is determined by the connection position specifying unit 311 based on the order and interval in which the device information is acquired. The device information of the device 100 connected to the specified panel-side connector 210 can be acquired. When determining the correspondence relationship for the connected device 100 every time it is connected as in this embodiment, the correspondence relationship is updated for all the devices 100 when the layout of the device 100 is changed. This makes it easy to update the correspondence table.

  Further, in the system operation panel 10 according to the present embodiment, the active tag 120 is illustrated as an example of the device information storage unit and the IC tag, but it is needless to say that the present invention is not limited to this example. For example, a wireless IC tag such as a passive tag can be used instead of the active tag 120. In this case, the wireless communication unit 312 may emit a radio wave for reading the passive tag when the connection position specifying unit 311 specifies the connection position. When using a passive tag, it is also possible to arrange the device 100 after communicating device information between the device 100 to be connected and the wireless communication unit 312. However, when the device information is automatically acquired by arranging the device 100 as in the present embodiment, the labor for arranging the device 100 is reduced, and for example, the device 100 different from the device information. It is possible to prevent the creation of an incorrect correspondence table that may occur when the user has placed the. Further, instead of the active tag 120, another wireless communication device and a storage unit can be attached to the device 100. However, if the active tag 120 is used as in this embodiment, the configuration of the device 100 itself can be reduced. In addition, the active tag 120 can be easily placed on the device 100.

  Further, in the system operation panel 10 according to the present embodiment, the case where device information is transmitted by performing wireless communication has been described, but the present invention is not limited to this example. For example, a terminal for transmitting device information can be newly provided in the panel-side connector 210 and the device-side connector 110, or device information can be transmitted to an existing terminal. However, when device information is transmitted wirelessly as in the present embodiment, it is not necessary to provide a new terminal or add a new line connected to an existing terminal, and each device 100 is easily created. be able to.

  In addition to transmitting the device information wirelessly or by wire as in the system operation panel 10 according to the present embodiment or the modification described here, it is also possible to transmit the device information by other methods. An example of a system operation panel capable of transmitting such device information will be described as a second embodiment.

<Configuration of System Operation Panel 40 According to Second Embodiment>
In the system operation panel according to the second embodiment described below, a configuration for acquiring device information, a configuration for specifying a panel-side connector, and basic configurations and operations other than those operations are the same as those in the first embodiment. This is the same as the system operation panel 10 concerned. Therefore, hereinafter, the description will focus on the differences from the system operation panel 10 according to the first embodiment.

  FIG. 13 is an explanatory diagram for explaining a configuration of a system operation panel according to the second embodiment of the present invention. As shown in FIG. 2, the system operation panel 40 according to the present embodiment includes a device 400, a panel 500, and a connection control unit 600.

(Device 400)
As shown in FIG. 14, the device 400 includes a two-dimensional or one-dimensional code 420 instead of the active tag 120.

  The code 420 is an example of a storage unit, in which device information is recorded, and is arranged on the surface of the device 400 that faces the panel 200. Examples of the code 420 include a QR code (Quick Response Code, registered trademark), PDF417, Data Matrix, and Maxi Code in the case of two dimensions. In the case of a one-dimensional code, for example, a bar code or the like can be given.

(Panel 500)
As shown in FIG. 15, the panel 500 includes a through hole 530 in addition to the other configuration of the panel 200 according to the first embodiment.

  The through hole 530 is formed at a position corresponding to the code 420 on the panel 500, and allows the code 420 to be read even after the device 400 is arranged on the panel 500.

(Connection control unit 600, etc.)
Furthermore, the system operation panel 40 is configured to acquire device information and position information instead of the wireless communication unit 312 and the connection position specifying unit 311 included in the system operation panel 10 according to the first embodiment. , A moving unit 720, a code reading unit 612, and a connection position specifying unit 611.

  The imaging unit 710 and the code reading unit 612 are examples of a code reading unit. The imaging unit 710 is disposed on the back side of the panel 500, and the code reading unit 612 is included in the wireless communication unit 312 according to the first embodiment. Placed instead. Then, the imaging unit 710 images the code 420 from the back side of the panel 500 through the through hole 530. Such an imaging unit 710 can be configured by various imaging means such as a monochrome camera, a color camera, a code reader using infrared rays, and the like. The code reading unit 612 reads the device information represented by the code 420 from the image captured by the imaging unit 710. Then, the code reading unit 612 outputs the read device information to the device information acquisition unit 313.

  The moving unit 720 is an example of a moving unit, and includes, for example, a rotating body such as a motor and a tire, a rail, and the like, and moves the imaging unit 710 along the panel 500. More specifically, the moving unit 720 moves the imaging unit 710 so that the imaging unit 710 images all the through holes 530 (that is, the code 420 via the through holes 530). That is, the imaging unit 710 scans all the through holes 530 from the back surface of the panel 500 by the moving unit 720.

  The connection position specifying unit 611 is an example of a connector specifying unit. The connection position specifying unit 611 acquires position information (such as a two-dimensional coordinate) of the imaging unit 710 moved by the moving unit 720 from the moving unit 720, and the imaging unit is obtained from the position information. 710 identifies the panel-side connector 210 on which the device 400 that captured the code 420 is arranged. Then, the connection position specifying unit 611 outputs an identification number (an example of position information for specifying a connector) corresponding to the specified panel-side connector 210 to the correspondence determining unit 314.

<Operation of System Operation Panel 40 According to Second Embodiment>
As above, the configuration different from the system operation panel 10 according to the first embodiment has been described among the configurations of the system operation panel 40 according to the present embodiment. Next, the operation of the system operation panel 40 according to the second embodiment of the present invention will be described with reference to FIG. The system operation panel 40 is the same as the system operation panel 10 according to the first embodiment except that the operation is different during production or layout change. Therefore, here, the operation during production or layout change by the system operation panel 40 according to the present embodiment will be described.

(Operation during production or layout change)
In the system operation panel 10 according to the first embodiment, the device information is acquired every time a device is arranged. However, the system operation panel 40 according to the present embodiment first processes step S401, and all the operations are performed. Device 400 is placed on panel 500. Then, step S403 is processed, and in step S403, the moving unit 720 moves the imaging unit 710 to a position where at least one of the through holes 530 can be imaged. Then, the process proceeds to step S405.

  In step S <b> 405, the connection position specifying unit 611 acquires position information of the imaging unit 710 from the moving unit 720. Then, the connection position specifying unit 611 specifies the panel-side connector 210 corresponding to the through-hole 530 that the image pickup unit 710 is about to pick up from the position information of the image pickup unit 710, and the position information of the specified panel-side connector 210 ( For example, the identification number) is output to the correspondence determining unit 314. Then, the process proceeds to step S407.

  In step S <b> 407, the imaging unit 710 images the code 420 of the device 400 through the through hole 530. The code reading unit 612 receives this captured image and reads the device information represented by the code 420. Then, the device information acquisition unit 313 acquires the read device information and outputs it to the correspondence determination unit 314. Note that step S405 and step S407 may be processed at the same time, or step S405 may be processed after step S407 is processed. After step S407 (or step S405), the process proceeds to step S409.

  In step S409, the correspondence determining unit 314 creates a first correspondence table as shown in FIG. 8 based on the position information and the device information, and records the first correspondence table in the correspondence table storage unit 321. Then, the process proceeds to step S411.

  In step S411, the correspondence determining unit 314 performs the processing shown in FIG. 9 based on the first correspondence table, the tag table as shown in FIG. 6 and the I / O table as shown in FIG. A second correspondence relationship table as shown is created and recorded in the correspondence relationship table storage unit 321. Then, the process proceeds to step S413.

  In step S413, the correspondence determination unit 314 confirms whether or not all the through holes 530 on the panel 200 have been imaged. This confirmation is performed, for example, by confirming whether or not the imaging unit 710 has passed the positions corresponding to all the through holes 530 based on the movement path of the imaging unit 710 moved by the moving unit 720. Also good. The correspondence determining unit 314 can also determine that all the through holes 530 have been imaged when a predetermined time has elapsed since the imaging unit 710 started imaging. Then, when all the through holes 530 (that is, the code 420 of the device 400) are not imaged, the processing from step S403 is executed again. When all the through holes 530 have been imaged, the production of the system operation panel 40 or the layout change operation ends. By such an operation, the connection control unit 300 can associate the device 400 with the facility device.

<Example of effects by system operation panel 40 according to the second embodiment>
The system operation panel 40 according to the second embodiment of the present invention has been described above.
According to the system operation panel 40, the same effects as those of the system operation panel 10 according to the first embodiment can be obtained. That is, the system operation panel 40 can be easily manufactured, and the layout of each device 400 can be easily changed. Further, according to the system operation panel 40, the imaging unit 710 is unnecessary after manufacture, and can be removed. In this case, for example, when it is desired to change the layout, the layout of the system operation panel 40 can be easily changed in the same manner as described above by arranging the imaging unit 710 again. In addition, it is possible to reduce the manufacturing cost by using an inexpensive code 420 instead of the active tag 120 of the first embodiment. Furthermore, since the cord 420 can be configured as a simple seal, there is no need to consider the thickness of the cord 420 or the like.

<Modification Example of System Operation Panel 40 According to Second Embodiment>
In the present embodiment, the case where the moving unit 720 scans the imaging unit 710 and images all the through holes 530 has been described. However, the present invention is not limited to such examples. For example, the imaging unit 710 can include a plurality of through holes 530 in one captured image and simultaneously capture images. In this case, for example, the code reading unit 612 performs image analysis on the captured image, reads all the codes 420 included in the image, and further outputs position information in the image from which each code 420 is extracted to the connection position specifying unit 611. Output. Then, the connection position specifying unit 611 may specify the panel-side connector 210 based on the position information of the imaging unit 710 and the position information in the image of the code 420.

  In the above embodiment, examples of the code 420 include QR code (registered trademark), PDF417, Data Matrix, Maxi Code, barcode, and the like, but the present invention is not limited to these examples. For example, the code 420 may be a code representing the device information as characters. In this case, the code reading unit 612 includes, for example, an OCR (Optical Character Reader), and may read device information by reading characters included in the captured image.

  As mentioned above, although preferred embodiment of this invention was described in detail, referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present invention.

  For example, in the above-described embodiment, the case of wireless communication or the case of optical reading is described as the device information acquisition unit, but the present invention is not limited to these examples. For example, the device information can be acquired from the devices 100 and 400 using a physical key. In other words, for example, by placing a key having a different shape for each device information unique to each device on the surface that comes into contact with the panel of the device, and by arranging a switch that reads the key at a position corresponding to the key on the panel, It is also possible to acquire device information. In this case, each switch can read the shape of the key (that is, device information), and the device information acquisition unit 313 can acquire the device information.

  Moreover, although the said embodiment demonstrated the case where the identification number of each apparatus was included as apparatus information, this invention is not limited to this example. For example, the device information can include a network address of a signal flowing through a terminal included in each device. In this case, the tag table storage unit 315 can be omitted, and the correspondence determining unit 314 can include the network address included in the device information, the first correspondence table (see FIG. 8), and the I / O table (see FIG. 7). )), It is also possible to create a second correspondence table (see FIG. 9). In addition, the device information can include, for example, the specifications and functions of the device.

  In the above embodiment, the case where the connection switching unit 322 uses the second correspondence table to output an input signal to a terminal having an I / O address corresponding to the network address has been described as an example. . However, the present invention is not limited to this example. The devices 100 and 400 may be connected using an open field network (field bus) such as CC-Link (registered trademark), Interbus, PROFIBUS, or the like. In this case, an address on each field network can be an I / O address address. By using such an open field network, the wiring between the panels 200 and 500 and the devices 100 and 400 can be reduced.

  In the above embodiment, the connection switching unit 322 controls the transmission path by adding an I / O address or a network address to an input / output signal. However, the present invention is also limited to this example. Not. For example, the connection switching unit 322 may be configured with a plurality of switches, switching elements, and the like. In this case, the connection switching unit 322 can control the transmission path of the input / output signal by switching each switch according to the second correspondence table and changing the physical transmission path.

  In this specification, the steps described in the flowcharts are executed in parallel or individually even if they are not necessarily processed in time series, as well as processes performed in time series in the described order. Including processing to be performed. Further, it goes without saying that the order can be appropriately changed even in the steps processed in time series.
