Disclosure of Invention
In the display device described in patent document 1, the memory capacity is selected in accordance with the maximum capacity in consideration of the fact that various functions are executed. Therefore, there is a problem that the memory capacity required for the storage section and the processing section is increased in size along with the improvement of the function.
In the separately distributed programmable display device described in patent document 2, since the data collection unit generates an image and transmits the image to the touch monitor unit, it is necessary to continuously transmit image data from the data collection unit every time the displayed image is updated. Therefore, there is a problem that a load is concentrated on the data collection unit, and if a failure occurs on the transmission path, the display screen is interrupted, and redundancy is poor.
Further, since the capacity of image data is large compared to the device value, if the touch monitor units are added gradually, the load on the transmission path connecting the touch monitor units and the data collection unit and the load on the data collection unit increase with the increase in the number of touch monitor units. As a result, there is a disadvantage that the number of connectable devices or the specification to which the data collection unit is to be attached is limited.
In addition, in terms of performance of the data collection unit in the current split-distributed programmable display, even when the data collection unit is configured by a plurality of touch monitor units and one data collection unit, the data collection unit can generate only one image data. Therefore, the image data cannot be displayed individually for each touch monitor unit, and the same screen is displayed, so that the application as a display system cannot be expanded. There is a problem that, in order to realize a function of displaying image data individually for each touch panel portion, it is necessary to improve the performance of the data collection portion and create screen data including settings for generating image data, respectively.
In addition, in the current split-distributed programmable display, since the data collection unit transmits the device value only to the touch monitor unit having the request, it is necessary to request the device value from each touch monitor unit. As a result, it is difficult to display a plurality of touch monitor units as a multi-monitor in synchronization.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a programmable display device in which a touch monitor unit for generating display of image data and a data collection unit for collecting data are separated from each other, and in which the memory capacity of the touch monitor unit can be limited to a portion necessary for generating display of image data, and particularly, the remaining memory capacity when a display system using a plurality of touch monitors is configured can be suppressed, and a program executed by the programmable display device.
In order to achieve the above object, a programmable display according to the present invention is a programmable display including a data collection unit and a touch monitor, the data collection unit being provided separately from each other, the data collection unit acquiring a device value from a connected external device, the touch monitor generating and displaying image data corresponding to the device value from the data collection unit, the data collection unit and the touch monitor being connected via a transmission path, the programmable display including: a 1 st data storage unit that stores screen data that is a basis of image data displayed on the touch monitor unit; and a data processing unit that acquires a device value of the external device and transmits the device value to the touch monitor unit, the touch monitor unit including: a display unit; an input section; a 2 nd data storage unit that stores the screen data; a centralized processing unit that acquires the screen data from the data collection unit, stores the screen data in the 2 nd data storage unit, and acquires the screen data associated with an instruction from an operator from the 2 nd data storage unit if the instruction is received via the input unit; and a display generation unit that generates image data from the screen data acquired from the 2 nd data storage unit and the device value acquired from the data collection unit, and displays the image data on the display unit, wherein the display generation unit of the touch monitor unit updates the image data using the updated device value acquired from the data collection unit via the transmission path while the image data is displayed on the display unit.
ADVANTAGEOUS EFFECTS OF INVENTION
According to the present invention, since the memory capacity required for the touch monitor unit can be limited to the portion required for display generation, the memory capacity remaining when the programmable display is configured can be reduced as compared with a case where the maximum capacity is mounted in consideration of various functions.
Further, according to the present invention, since the image data generating function as the high-load processing exists in the touch monitor unit, there is an effect that the load applied to the transmission path and the data collecting unit can be reduced even in a display system using a plurality of touch monitors.

Detailed Description
A programmable display and a display program executed by the programmable display according to an embodiment of the present invention will be described in detail below with reference to the drawings. The present invention is not limited to these embodiments.
Embodiment mode 1
The programmable display device according to embodiment 1 has a configuration in which a data collection unit and a touch monitor unit that are provided independently of each other are connected via a transmission path. Fig. 1 is a block diagram schematically showing a functional configuration of a data collection unit constituting the programmable display according to embodiment 1, and fig. 2 is a block diagram schematically showing a functional configuration of a touch monitor unit constituting the programmable display according to embodiment 1.
The data collection unit 10 includes an external device connection interface 11, a data processing unit 13, a 1 st data storage unit 12, and a separation connection interface 14. The external device connection interface 11 is connected to an external device 50 such as a control target via a cable, a communication line, or the like. The external device 50 is, for example, a control device, a sensor, or the like, and is a device capable of outputting the state thereof as a device value. In addition, 1 or more external devices 50 are connected.
The 1 st data storage unit 12 stores, as log data, screen data, which is the basis of image data generated by the display generation unit 26 of the touch monitor unit 20, and device values acquired from the external device 50 and accumulated when the system is operated. The screen data is data that is the basis of image data generated by the display generation unit 26 of the touch monitor unit 20 and displayed on the display unit 23. The screen data has, for example, a layout structure section and a device value input section. The layout configuration unit is configured to keep the display content unchanged when the display unit 23 of the touch monitor unit 20 displays the device value, and is configured to define a frame or the like for an area where a graph is displayed when the graph is displayed. The layout structure unit further includes association information indicating an association with other screen data, such as a link to other screen data. The device value input unit is configured to change display contents according to an input device value, and in the case of graph display, the device value input unit is a graph or the like drawn in an area where the graph is displayed. There are a plurality of types of screen data, and the screen data used differs according to the instruction from the operator 60.
The data processing unit 13 transmits the screen data stored in the 1 st data storage unit 12 to the touch monitor unit 20 in accordance with an instruction from the touch monitor unit 20. Further, the device values collected from the external device 50 via the external device connection interface 11 are transmitted to the touch monitor unit 20. As the method of transmitting the device value, the device value updated by the external device 50 may be directly transmitted to the touch monitor unit 20, or the device value may be notified to the touch monitor unit 20 that it has been updated, and may be transmitted to the touch monitor unit 20 only when a data transmission request for the updated device value is received from the touch monitor unit 20.
The discrete connection interface 14 communicates with a touch monitor section 20 constituting a programmable display. The transmission path connecting the split connection interfaces 14 and 21 may be a dedicated cable, a general-purpose wired network such as ethernet, or a wireless network.
The touch monitor unit 20 includes a discrete connection interface 21, an input unit 22, a display unit 23, a centralized processing unit 24, a 2 nd data storage unit 25, and a display generation unit 26. The discrete connection interface 21 communicates with the data collection unit 10 constituting the programmable display.
The input unit 22 is a user interface for inputting to the display screen, and is input with a control instruction or the like to the control device by the operator 60. The display unit 23 is a display device that displays a display screen based on the screen data received from the data collection unit 10. As the display unit 23, a liquid crystal display device, an organic el (electro luminescence) display device, or the like can be used. The input unit 22 and the display unit 23 can be provided so as to overlap each other as a touch panel.
The central processing unit 24 stores the screen data received via the separate connection interface 21 in the 2 nd data storage unit 25. The control instruction input from the input unit 22 is transmitted to the data collection unit 10 via the split connection interface 21.
The centralized processing unit 24 constantly monitors the occupancy rate of the transmission path connected to the separation connection interface 21, and requests transmission of other screen data related to the image data currently generated for display in advance in accordance with the occupancy rate until a request from the operator 60 is made, and stores the received screen data in the 2 nd data storage unit 25. Further, since a predetermined number of screen data displayed in the past are also stored in the 2 nd data storage unit 25, when the screen data is selected again, the operation can be performed without increasing the occupancy rate of the transmission path.
The 2 nd data storage unit 25 stores the screen data received from the data collection unit 10. The 2 nd data storage unit 25 may have a capacity capable of storing at least 1 screen data. However, as described above, when a predetermined number of pieces of screen data displayed in the past are stored or screen data are stored in advance, a capacity capable of storing 2 or more pieces of screen data is required.
The display generation unit 26 generates image data to be displayed on the display unit 23 using the screen data stored in the 2 nd data storage unit 25 and the update information of the device value received from the data collection unit 10 via the separate connection interface 21, and displays the image data on the display unit 23.
As described above, the programmable display according to embodiment 1 includes: a data collection unit 10 that acquires a device value from an external device 50; and a touch monitor unit 20 for displaying to the operator 60, in which the programmable display generates image data to be displayed on the touch monitor unit 20 by the data collection unit 10 and transmits the image data to the touch monitor unit 20, and the programmable display transmits the device value from the data collection unit 10 to the touch monitor unit 20 and generates image data on the touch monitor unit 20.
Next, the processing at the time of the first start of the programmable display having the above-described configuration, the image data display processing, and the other screen data collection processing in the display processing will be described in order.
< processing at initial startup >
At the time of initial start-up, the screen data necessary for the generation of the image data is not stored in the touch monitor unit 20, and therefore the screen data necessary for the generation of the image data is transferred from the data collection unit 10 to the touch monitor unit 20. That is, in the touch monitor unit 20 of the programmable display, the separate connection interface 21 receives screen data from the data collection unit 10 at the time of initial start-up, and the centralized processing unit 24 stores the received screen data in the 2 nd data storage unit 25. Then, the screen data corresponding to the instruction of the operator 60 is read.
< image data display processing >
Fig. 3 is a flowchart showing an example of the procedure of the image data display processing of the touch monitor unit according to embodiment 1. First, upon receiving an instruction from the operator 60 from the input unit 22 (step S11), the touch monitor unit 20 retrieves and acquires screen data associated with the instruction received by the central processing unit 24 from the 2 nd data storage unit 25 (step S12). Then, the display generation unit 26 generates image data to be displayed on the display unit 23 based on the acquired screen data (step S13), and displays the generated image data on the display unit 23 (step S14). In addition, predetermined screen data may be provided instead of step S11 and step S12.
On the other hand, the data processing unit 13 of the data collection unit 10 monitors information on the device value of the external device 50 via the external device connection interface 11 (step S15), and determines whether or not the device value has been updated (step S16). If the device value is not updated (No at step S16), the process returns to step S15. In addition, when the device value is updated (Yes at step S16), the data processing unit 13 stores the updated device value (update information of the device value) in the 1 st data storage unit 12 (step S17). Then, the data processing unit 13 notifies the touch monitor unit 20 that the device value has been updated via the separation connection interface 14 (step S18). Note that, although not shown, the processing may be ended after a certain time period when there is no data transmission request from the touch monitor unit 20.
Upon receiving the notification via the separate connection interface 21, the central processing unit 24 of the touch monitor unit 20 determines whether the notified device value is included in the screen data acquired in step S12. If the notified device value is not included in the screen data (No in step S19), the screen data is put into a standby state. In addition, when the screen data is included (Yes at step S19), the centralized processing unit 24 transmits a data transmission request relating to the device value to the data collection unit 10 via the separate connection interface 21 (step S20).
The data processing section 13 of the data collection section 10, if receiving a data transmission request via the separate connection interface 14 (step S21), transmits the device value to the touch monitor section 20 (step S22).
Upon receiving the device value via the separate connection interface 21 (step S23), the central processing unit 24 of the touch monitor unit 20 transfers the device value to the display generation unit 26, updates the image data with the updated device value by the display generation unit 26 (step S24), and displays the updated image data on the display unit 23 (step S25). Then, the end of the display processing is notified to the data collection unit 10 (step S26), and the processing ends. In addition, if the data collection unit 10 receives a notification indicating the end of the display process (step S27), the process ends.
In the flowchart of fig. 3, the data collection unit 10 notifies the touch monitor unit 20 that the device value has been updated, and the touch monitor unit 20 transmits a data transmission request for the notified device value to the data collection unit 10, thereby receiving the device value. However, the processing in steps S18 to S21 may be omitted, and the data collection unit 10 may transmit the updated device value to the touch monitor unit 20 immediately after storing the device value in the 1 st data storage unit 12 in step S17.
< other Picture data Collection processing in display processing >
Fig. 4 is a flowchart showing an example of a procedure of another screen data acquisition process in the image data display process of the touch monitor unit. In the touch monitor unit 20, while the display generation unit 26 displays the image data on the display unit 23, the centralized processing unit 24 monitors the occupancy rate of the transmission path to which the discrete connection interface 21 is connected (step S51), and determines whether or not the occupancy rate is equal to or less than a predetermined value (step S52). If the occupancy rate is greater than the predetermined value (No at step S52), the process returns to step S51.
When the occupancy rate is less than or equal to the predetermined value (Yes at step S52), the centralized processing unit 24 transmits a request for transmission of another screen data associated with the screen data that is the basis of the image data currently displayed on the display unit 23 to the data collection unit 10 (step S53). It is preferable that the request for transmission of the other screen data by the centralized processing unit 24 is performed in advance of the prediction of the request for transmission of the other screen data by the operator 60. In response to a request for transmitting other screen data from the centralized processing unit 24, the data processing unit 13 of the data collection unit 10 extracts the designated screen data from the 1 st data storage unit 12 and transmits the screen data to the touch monitor unit 20. The predetermined value of the occupancy rate used for the determination at step S52 may be a value that enables the screen data to be transmitted without applying a load to the transmission path. Before transmitting the request for transmitting the other screen data in step S53, the central processing unit 24 may determine whether or not the other screen data is stored in the 2 nd data storage unit 25, and may issue the request for transmitting the other screen data if the other screen data is not stored in the 2 nd data storage unit 25.
If the other screen data is received via the separate connection interface 21 (step S54), the central processing unit 24 stores the other screen data in the 2 nd data storage unit 25 (step S55). Then, if an instruction to display other screen data is received from the operator 60 (step S56), the central processing unit 24 extracts other screen data acquired from the data collection unit 10 in advance from the 2 nd data storage unit 25 (step S57). Then, the display generation unit 26 generates image data using the extracted other screen data (step S58), displays the image data based on the other screen data on the display unit 23 (step S59), and the process ends.
In the above description, the input unit 22 and the display unit 23 may be members to which the external device 50 such as a projector, a monitor, and a motion sensor is connected, or the touch monitor unit 20 itself may be an external device 50 such as a tablet or a mobile terminal.
In embodiment 1, since the memory capacity required for the touch monitor unit 20 can be limited to a portion required for display generation, there is an effect that the remaining memory capacity in the case of configuring the programmable display can be reduced as compared with the case of mounting the maximum capacity in consideration of various functions.
The data collection unit 10 and the touch monitor unit 20 constitute a programmable display, and the touch monitor unit 20 acquires screen data, which is the basis of image data to be displayed on the display unit 23, from the data collection unit 10 in advance, generates image data using the screen data and the device value from the data collection unit 10, and displays the image data on the display unit 23. This has the effect that the occupancy rate on the transmission path between the data collection unit 10 and the touch monitor unit 20 can be reduced and the load applied to the data collection unit 10 can be reduced, as compared with the case where the image data is transmitted from the data collection unit 10 to the touch monitor unit 20. In addition, although it is necessary to secure the capacity of the 2 nd data storage unit 25 in the touch monitor unit 20, and the 2 nd data storage unit 25 is used to store the image data transmitted every time the device value is updated, this embodiment 1 does not require the capacity, and therefore, there is an effect that the capacity of the 2 nd data storage unit 25 can be made smaller than that in the related art.
For example, in the current configuration, since the touch monitor unit and the data collection unit are integrated, the memory capacity is selected so that various data including screen data, data used by systems such as the OS and a communication driver with an external device, and log data such as device values used in the past by the data processing unit can be stored. The screen data has a relationship with the resolution, but is configured to be able to store 500 screens at the maximum. On the other hand, in embodiment 1, the screen data and the other data are distinguished, and only a plurality of screen data are stored in the touch monitor unit 20. That is, the memory capacity required for the touch monitor unit 20 is minimized, and the other data is stored by the memory capacity of the data collection unit. This has the effect of reducing the remaining memory capacity when configuring a display system using a plurality of touch monitor units 20.
Further, compared to the conventional programmable display, the touch monitor unit 20 can be reduced in weight and thickness, and a customer can select various screen sizes and resolutions from one data collection unit 10, so that a system with a high degree of freedom in layout can be constructed.
The touch monitor unit 20 monitors the occupancy rate of the transmission path between the touch monitor unit 20 and the data collection unit 10 during the display processing, and acquires, from the data collection unit 10, other screen data associated with the screen data that is the basis of the image data currently being displayed when the occupancy rate of the transmission path is equal to or less than a predetermined value. This enables acquisition of other screen data when the occupancy rate of the transmission path is low in advance before a request from the operator 60 is made. Further, by storing a predetermined number of screen data displayed in the past in the 2 nd data storage unit 25, when the screen data is selected again, it is possible to quickly display the image data without increasing the occupancy rate of the transmission path. Further, the occupancy rate on the transmission path can be smoothed, the occupancy rate on the transmission path can be reduced, and the load applied to the transmission path can be reduced.
Embodiment mode 2
Fig. 5 is a block diagram schematically showing an example of the configuration of the programmable display according to embodiment 2. In this example, the case where a plurality of touch monitor units 20-1 to 20-3 are connected to 1 data collection unit 10 is shown for the programmable display. Note that the configurations of the data collection unit 10 and the touch monitor unit 20 are the same as those described in embodiment 1, and therefore, the description thereof is omitted.
The plurality of data collection units 10 and the touch monitor units 20-1 to 20-3 configured as described above operate such that transmission requests for different device values are transmitted to the data collection units 10 in accordance with the respective touch monitor units 20-1 to 20-3. The data collection unit 10 transmits a device value corresponding to a request for transmitting the device value from each of the touch monitor units 20-1 to 20-3. That is, each of the touch monitor units 20-1 to 20-3 generates image data using screen data and a device value in accordance with an instruction from the operator 60, displays the image data on the display unit 23, and when the device value is updated, acquires the updated device value (update information of the device value) from the data collection unit 10 and performs display processing. Therefore, the data collection unit 10 does not need to generate image data of the plurality of touch monitor units 20-1 to 20-3 and transmit the image data to the touch monitor units 20-1 to 20-3.
In the example of fig. 5, the number of the data collection units 10 is 1, but a plurality of the data collection units 10 may be present.
According to embodiment 2, image data can be displayed on each of the touch monitor units 20-1 to 20-3 based on a plurality of screen data stored in 1 or more data collection units 10, and thus, both scalability as a display system and centralized screen data management can be realized. Further, by collecting the screen data in the data collection unit 10, maintenance can be facilitated.
Embodiment 3
When a plurality of touch monitor units are connected to 1 or a plurality of data collection units, data can be transmitted from the data collection units to the plurality of touch monitor units in synchronization. Fig. 6 is a flowchart showing an example of the procedure of the data transmission method in the case where a plurality of touch monitor units are connected to the data collection unit according to embodiment 3. Here, as shown in FIG. 5, a case where 3 touch monitor units 20-1 to 20-3 are connected to 1 data collection unit 10 is exemplified.
The data processing unit 13 of the data collection unit 10, if it receives a device value transmission request from 1 of the connected touch monitor units 20 (for example, the touch monitor unit 20-1) (step S71), determines whether it is in the synchronous display mode (step S72). This determination is made, for example, by setting whether or not the item data stored in advance in the 1 st data storage unit 12 in the data collection unit 10 is displayed synchronously, and by determining whether or not the item data is displayed synchronously. Here, the item data is data including screen data which is a base of a screen displayed on the display unit 23 of the touch monitor unit 20 and information which associates the screen data and concentrates the screen data. The setting of whether to synchronize the display is made by the user.
In the case of the synchronous display mode (Yes at step S72), the data processing unit 13 of the data collection unit 10 transmits the same device value to all the touch monitor units 20-1 to 20-3 in synchronization (step S73), and the process ends.
On the other hand, in the case where the display format is not the synchronous display format (No at step S72), the data processing unit 13 of the data collection unit 10 transmits only the device value to the touch monitor unit 20-1 (step S74), and the process ends.
The synchronized image may be an image having a resolution that can be displayed by 1 touch monitor unit 20, such as a mirror image display, or may be a multi-monitor display in which the resolution is expanded by combining and linking a plurality of touch monitor units 20.
According to embodiment 3, since the device values corresponding to the requests from 1 touch monitor unit 20 are transmitted from the data collection unit 10 to the other touch monitor units 20 in synchronization with each other, it is possible to generate images synchronized among the touch monitor units 20. In addition, the number of touch monitor units 20 can be easily increased, and synchronization can be easily performed in some cases.
The processing of the data collection unit 10 and the touch monitor unit 20 of the programmable display can be configured as a program in which the processing procedure is stored. The program can be executed by a portable information processing terminal such as the programmable display or the tablet terminal. The program is recorded on a computer-readable recording medium such as a hard Disk, ssd (solid state drive), "フロッピー (flash)" Disk, cd (compact Disk) -ROM, MO (magnetic-Optical Disk), DVD (Digital Versatile Disk or Digital Video Disk). The program can also be distributed via a network (communication line) such as the internet.
