Description

  The present invention relates to a monitoring control apparatus used in a remote monitoring control system that performs load monitoring control by communication.

  2. Description of the Related Art Conventionally, a technique is known in which a transmission signal including switch on / off information is transmitted through a communication line in order to perform remote monitoring control of a load, and a relay for turning on / off a load is opened / closed by the transmission signal.

  As this type of remote monitoring control system, for example, an operation terminal having a switch and a control terminal having a relay for turning on / off a load are provided as a terminal device, and a centralized control type provided with a transmission unit as a center device There are things. A plurality of operation terminals and control terminals may be provided. The transmission unit, the operation terminal, and the control terminal are connected to a two-wire communication line, and the transmission unit is connected to the operation terminal and the control terminal using terminal addresses set individually for the operation terminal and the control terminal. Recognize each control terminal separately.

  The transmission unit includes a memory that stores a control table that is a data table in which operation terminals and control terminals are associated with each other by addresses. When this switch unit is notified of switch ON / OFF information in any of the operation terminals using a transmission signal (using a time division multiplex transmission signal), the transmission unit is associated with the operation terminal by the control table. An instruction to open / close the relay is transmitted to the control terminal using the transmission signal. In response to this instruction, the relay is opened and closed in the control terminal. Therefore, the load is controlled according to the on / off state of the switch.

  By the way, in the above-described remote monitoring and control system, a monitoring control device that is used by being connected to a communication line has been proposed as one capable of monitoring and controlling a large number of loads at one place (for example, see Patent Document 1). .

  The monitoring and control apparatus described in Patent Document 1 includes a display device including a liquid crystal display device, a transparent touch switch arranged so as to overlap the screen of the display device, a load corresponding to display control of the display device and operation of the touch switch. A control unit that performs control, and each of the touch switches is defined as an area defined by an operation button displayed on a display screen. That is, the user can control the load corresponding to the operation button by touching the operation button on the screen of the display. Further, the operating state of each load to be controlled is displayed on the display. In this configuration, which operation button on the display screen is associated with which load is determined by an address assigned to each operation button.

  For this type of monitoring and control device, a function of automatically turning off the screen display of the display when the touch switch is not operated for a predetermined time or longer and resuming the screen display when the operation of the touch switch is resumed is added. Thus, it is considered to reduce wasteful power consumption and extend the life of the display.

  Here, when the monitoring control device having the above-described configuration is used, the number of operation buttons displayed on one screen of the display unit increases as the number of loads increases. Since the interval between the buttons is also narrowed, erroneous operation of the operation buttons is likely to occur. Therefore, an operation page that is displayed on the display unit according to a user's operation is displayed on the display unit with an operation page that is alternatively selected from a plurality of operation pages including a plurality of operation buttons of different combinations. It can be considered to be switchable. Thereby, it is possible to display operation buttons corresponding to a large number of loads by switching the display content of the screen while relatively reducing the number of operation buttons displayed per screen of the display.

The monitoring control device 1 displays the operating state of the load L based on the received load control response.

  By such an operation, the operation of the monitoring control device 1 can be reflected in the control of the load L.

(Embodiment 1)
As shown in FIG. 4, the monitoring control device 1 of the present embodiment includes a display 2 in which a backlight is integrated with a liquid crystal display, and a transparent plate-like shape that is disposed on the screen (front) of the display 2. The touch switch 3 is provided on the front surface of the body 4. The display device 2 is not limited to a liquid crystal display device, and may be, for example, an electronic paper or an organic EL display.

  The display 2 uses a matrix display type in which a large number of pixels are arranged in a matrix form vertically and horizontally, and displays graphics and characters in color according to the combination of pixels. The touch switch 3 is a resistive pressure-sensitive touch switch that arranges a large number of contact portions made of transparent electrodes on a transparent sheet-like member, and outputs which part of the sheet-like member is touched when a finger touches the sheet-like member It constitutes a touch panel display together with the display 2. The touch switch 3 is not limited to the resistance pressure-sensitive method, and may be, for example, a capacitive method or an optical type.

  The touch panel display is for accepting an operation input from the user, and the area defined by the operation button displayed on the screen of the display unit 2 in the touch switch 3 is a load control switch. That is, the user can control the load L corresponding to the operation button by touching the operation button on the screen of the display 2.

  As shown in FIG. 1, the monitoring control device 1 includes a power supply circuit 6 that is connected to a power supply terminal portion 5 for connecting a power supply line Lp and supplies DC power to an internal circuit, and a communication terminal portion 7 for connecting a communication line Ls. And a control circuit 10 that performs display control of the display 2 and load control according to operation input of the touch switch 3. The control unit 10 has a microcomputer as a main component, and operates according to programs and data written in the control information storage unit 16 and the communication information storage unit 17. The control information storage unit 16 stores information necessary for load control such as a control table indicating a correspondence relationship between the switch (operation button) and the address of the control terminal T, and the communication information storage unit 17 stores information necessary for communication. The address (self-monitoring control device 1) and the like are stored. Further, a clock unit 18 that outputs time information indicating the current time to the control unit 10 and a page information storage unit 19 to be described later are provided. As the communication circuit 8, for example, a serial transmission circuit such as RS-485, an Ethernet (registered trademark) transmission circuit, or the like is applicable.

  Furthermore, the monitoring control device 1 generates an operation sound when the touch switch 3 is operated, the activation switch 9 that constitutes an operation input unit for accepting the user's operation together with the touch switch 3, the LED 20 indicating power on / off, and the touch switch 3. A buzzer 21 is provided, and a socket 22 into which an external storage medium such as a memory card can be mounted. The start switch 9 is a mechanical switch disposed below the display unit 2 on the front surface of the body 4 and is used to start the touch panel display and cause the display unit 2 to start screen display. The external storage medium is used for settings relating to load control. Note that the control unit 10, the communication circuit 8, and the like in the monitoring control device 1 may be separated from the user interface such as the display 2 and the operation input unit and provided as a separate parent device.

  Here, the control unit 10 sends out a communication command (load control request) on the communication line Ls in accordance with the operation of the switch (operation button), and a setting mode for assigning addresses and making various settings for each switch. These two operation modes can be switched. Switching between these operation modes is performed by a predetermined operation such as a long press of the start switch 9, for example.

  In the operation mode, the control unit 10 displays the load state (the operation state of the load L) on the display 2 based on the communication command (load control response) acquired by the communication circuit 8, and is associated with the display content. The load control according to the operation of the touch switch 3 is performed. That is, the display device 2 is also used as a state display unit that displays the current operation state of each load to be monitored and controlled, and the user can control the load by operating the touch switch 3 according to the display. It becomes.

  Specifically, as shown in FIG. 5, the control unit 10 displays a plurality of operation buttons B11 to B14, B21 to B24, B31 to B34 on the screen of the display device 2 (hereinafter, unless otherwise distinguished, simply “ An operation screen including “operation button B” is displayed, and an area of the touch switch 3 that overlaps each operation button B on the screen of the display 2 is a switch. The user can give an operation input for load control by touching each switch of the touch switch 3 (part corresponding to each operation button B). Therefore, the user can control the load L corresponding to the operation button B by touching any operation button B.

  The control terminal T that constructs the remote monitoring control system together with the monitoring control device 1 is connected to the power supply terminal portion 25 for connecting the power supply line Lp as shown in FIG. 6, and the power supply circuit 26 that supplies DC power to the internal circuit. And a communication circuit 28 that is connected to the communication terminal unit 27 for connecting the communication line Ls and transmits / receives a communication command, and a control unit 30 that mainly includes a microcomputer. The control unit 30 operates according to the program and data written in the control information storage unit 31 and the communication information storage unit 32, and the load control unit 34 turns on / off the power output from the load terminal unit 33 to the load L. Control the operating state of L.

  By the way, since the monitoring and control apparatus 1 targets a large number of loads L11 to L14, L21 to L24, and L31 to L34, operations corresponding to all the loads L11 to L14, L21 to L24, and L31 to L34 are assumed. When the buttons B11 to B14, B21 to B24, and B31 to B34 are displayed on one screen of the display device 2, the display size of each operation button B becomes small, and it becomes difficult to see the display of the load state, or the area of each operation button B May become smaller and difficult to touch.

  Therefore, in the present embodiment, in order to relatively reduce the number of display of the operation buttons B per screen of the display 2, display control means for causing the control unit 10 to display the operation buttons B separately on the display 2. 11 and a function as page switching means 12 for switching the operation button B displayed on the display 2. Here, the display control means 11 selects operation pages P1 to P3 that are alternatively selected from a plurality of operation pages P1 to P3 including a plurality of operation buttons B of different combinations as shown in FIG. The page switching means 12 is displayed on the display device 2 and switches the operation pages P1 to P3 to be displayed on the display device 2 in accordance with a user operation.

  Here, operation pages P1 to P3 each capable of displaying four operation buttons B are adopted, and tab-like page switching buttons D1 to D3 displayed above each operation page P1 to P3 are alternatively selected. As a result, any one of the operation pages P1 to P3 is displayed.

  Each operation page P1 to P3 includes a combination of operation buttons B corresponding to the loads L in the same installation areas A1 to A3. For example, the page switching button D1 is selected as shown in FIG. In the state (highlighted state), the operation page P1 including the operation buttons B11 to B14 corresponding to the loads L11 to L14 in the installation area A1 is displayed. When the page switching button D2 is selected in this state, the screen display of the display device 2 is updated and includes operation buttons B21 to B24 corresponding to the loads L21 to L24 in the installation area A2, as shown in FIG. The operation page P2 is displayed. Similarly, when the page switching button D3 is selected, an operation page P3 including operation buttons B31 to B34 is displayed as shown in FIG. 5C. In each of the operation pages P1 to P3, two operation buttons B are respectively displayed in the vertical direction (up and down direction in FIG. 5) on the screen and in total in four rows in the horizontal direction (left and right direction in FIG. 5). . Here, it is assumed that an operation page P1 including operation buttons B11 to B14 is displayed as an initial screen when the monitoring control apparatus 1 is turned on.

  The plurality of operation buttons B only have to be distributed to the operation pages P1 to P3 according to their attributes, and the corresponding operation pages B of the corresponding load L installation areas A1 to A3 are assigned to the same operation page. For example, the operation buttons B having the same load L type (for example, different lighting equipment and air conditioning equipment) may be distributed to the same operation pages P1 to P3.

  Each operation button B is also used for displaying the operating state of the corresponding load L. For example, if all of the loads L21 to L24 are in an off state, the operation buttons B21 to B24 are displayed with dotted lines as shown in FIG. 5B, whereas if the load L21 is turned on, the operation buttons B21 to B24 correspond to the load L21. The peripheral edge of the operation button B21 to be displayed is indicated by a solid line as shown in FIG. At this time, the display color of the operation button B is also changed according to the on / off state of the load L (for example, off: green, on: red).

  By the way, the monitoring control device 1 of the present embodiment controls the function of the display interruption means 13 for turning off the screen display of the display device 2 when the touch switch 3 and the start switch 9 that are operation input units are not operated for a predetermined time or longer. 10 to have. Further, the control unit 10 has a function as the display restarting means 14 for restarting the screen display of the display device 2 when the operation of the start switch 9 is operated while the screen display is turned off.

  That is, the display interruption means 13 turns off the backlight of the display device 2 and turns off the screen display of the display device 2 (that is, the liquid crystal display) when the operation at the operation input unit is not detected for a predetermined auto-off time or longer. Stop the output to the device. On the other hand, when the display restarting means 14 detects a predetermined operation (here, the start switch 9 is pressed) in the operation input unit with the display 2 turned off, the backlight is turned on and the screen of the display 2 is displayed. Resume display. Accordingly, when the operation input unit is not operated for a long time, the backlight and the liquid crystal display can be turned off to extend the life of the display 2 and reduce the power consumption. The auto-off time is set in the setting mode.

  Here, as shown in FIG. 1, the control unit 10 determines the operation pages P <b> 1 to P <b> 3 to be displayed first on the screen of the display device 2 when the display resuming unit 14 resumes the screen display. It has the function as. Furthermore, the page information storage unit 19 stores a schedule table in which operation pages P1 to P3 designated in advance for each time zone are associated with the time zone as designated pages. When the screen display is resumed, the page determination unit 15 refers to the schedule table and first displays a designated page corresponding to the time zone to which the resume point belongs. Therefore, even if operation pages P1 to P3 with high operation frequency differ depending on the time zone, by selecting operation pages P1 to P3 with high operation frequency for each time zone individually as designated pages, in any time zone Also, the screen display can be resumed from the operation pages P1 to P3 having a high operation frequency. Here, the designation page for each time zone in the schedule table is arbitrarily designated by a user operation in the setting mode.

  Specifically, one day (24 hours) is morning (6:00 to 8:59), daytime (9:00 to 17:59), and night (18:00 to 5:59) depending on the time of day. The schedule table in which the designated page is designated for each time zone (morning, noon, and night) is stored in the page information storage unit 19. Here, as an example, the loads L11 to L14 in the installation area A1 are frequently operated in the morning time zone, the loads L21 to L24 in the installation area A2 are frequently operated in the morning time zone, and the night time zone is Assume that the loads L31 to L34 in the installation area A3 are frequently operated. Therefore, the operation page P1 including the operation buttons B11 to B14 in the morning time zone, the operation page P2 including the operation buttons B21 to B24 in the daytime time zone, and the operation page P3 including the operation buttons B31 to B34 in the night time zone. Each page is designated.

  In this case, as shown in FIG. 8, when the start switch 9 is pressed in a state where the screen display is off (S1: Yes), the control unit 10 acquires time information indicating the current time from the clock unit 18, Whether the current time belongs in the morning (6:00 to 8:59), noon (9:00 to 17:59), or night (18:00 to 5:59) Is determined (S2). At this time, if the current time belongs to the morning time zone, the operation page P1 shown in FIG. 5A is first displayed when the screen display is resumed (S3). On the other hand, when the current time belongs to the noon time zone, the operation page P2 shown in FIG. 5B is displayed first (S4), and when the current time belongs to the night time zone, FIG. The operation page P3 shown is first displayed (S5).

  Next, the operation of the monitoring control device 1 of the present embodiment will be described with reference to the sequence diagram of FIG. Here, an operation for turning off the load L21 is illustrated in the daytime period when the loads L21 to L24 in the installation area A2 are frequently operated.

  When the auto-off time elapses without operating either the touch switch 3 or the start switch 9, the control unit 10 turns off the screen display of the display device 2 (S11). Thereafter, when the start switch 9 is pressed (S12), the control unit 10 displays the operation page P2 which is a designated page corresponding to the time zone (9:00 to 17:59) to which the current time belongs, as a page information storage unit. 19 is read out (S13). And the screen display of the display 2 is restarted from the state (screen of FIG. 7) which displays the said operation page P2 (S14).

  When the operation button B21 corresponding to the load L21 is touched while the operation page P2 is displayed (S15), a load control request is transmitted from the monitoring control device 1 to the control terminal T21 (S16). ). Upon receiving the load control request, the control terminal T21 analyzes the received communication command (load control request) and recognizes that it is a load control request, so that the control terminal T21 turns on the load L21 according to the control content. The power supply control circuit 34 is controlled (S17). Thereafter, the control terminal T21 returns a load control response indicating that the load L21 is on to the monitoring control device 1 (S18).

  Upon receiving the load control response, the monitoring control device 1 analyzes the received communication command (load control response), and recognizes that it is a load control response, the operation button B21 corresponding to the load L21 according to the control content. The display state is changed and a screen as shown in FIG. 7 is displayed (S19). This display can inform the user of a change in the operating state of the load L21.

  As described above, the user can operate the operation button B21 without switching the operation pages P1 to P3 to turn off the load L21 after the screen display is resumed. The process (S16 to S19) can be executed by the monitoring control device 1.

  According to the monitoring control device 1 having the configuration described above, the operation buttons B corresponding to each load L are displayed in a plurality of operation pages P1 to P3, and the number of operation buttons B displayed on one screen is reduced. However, when the screen display is resumed, the operation pages P1 to P3 designated in advance for each time period can be displayed first. Therefore, even when the user's behavior pattern depends on the time zone, and the operation pages P1 to P3 with high operation frequency differ for each time zone, the operation pages P1 to P3 with high operation frequency for each time zone. Is designated as the designated page, it is possible to save the trouble of switching the operation pages P1 to P3 after the screen display is resumed. That is, after the screen display is resumed, an operation for switching the operation pages P1 to P3 to operate the operation button B having a high operation frequency becomes unnecessary, and the operation button B can be operated immediately, so that the operability is improved.

  In the present embodiment, morning, noon, and night are illustrated as time zones in the schedule table. However, the time zone may be determined in one day (24 hours), and the time zone can be specifically set. Whether to classify according to such rules is not limited to the above example. In addition, here, the schedule table having the same contents is repeatedly used in a daily cycle, but the contents of the schedule table may be changed every day.

(Embodiment 2)
The monitoring control apparatus 1 of the present embodiment is different from the monitoring control apparatus 1 of the first embodiment in that the time zone in the schedule table is determined in units of one day with a period of one week.

  Specifically, one week is divided into three periods of weekdays (Monday to Friday), Saturday, and Sunday according to the day of the week, and each period (weekday, Saturday, Sunday) is set as a time zone in the schedule table. Here, as an example, the loads L11 to L14 in the installation area A1 are frequently operated on weekdays, the loads L21 to L24 in the installation area A2 are frequently operated on Saturdays, and the loads L31 to L34 in the installation area A3 on Sundays. Suppose that is frequently operated. Therefore, the operation page P1 including the operation buttons B11 to B14 on weekdays, the operation page P2 including the operation buttons B21 to B24 on Saturday, and the operation page P3 including the operation buttons B31 to B34 on Sunday are respectively specified pages. Here, the control unit 10 can acquire not only the time information but also day information indicating the day of the week from the clock unit 18.

  In this case, as shown in FIG. 10, when the start switch 9 is pressed while the screen display is off (S21: Yes), the control unit 10 acquires day information indicating the day of the week from the clock unit 18. Then, it is determined whether the current day belongs to a weekday (Monday to Friday), Saturday, or Sunday (S22). At this time, if the current day belongs to a weekday, the operation page P1 shown in FIG. 5A is first displayed when the screen display is resumed (S23). On the other hand, when the current day is a Saturday, the operation page P2 shown in FIG. 5B is displayed first (S24). When the current day is a Sunday, the operation page P3 shown in FIG. 5C is displayed first. (S25).

  According to the configuration described above, the operation pages P1 to P3 that are initially displayed on the display device 2 when the screen display is resumed can be designated in advance for each time zone divided by day of the week. Therefore, even when the user's behavior pattern depends on the day of the week and the operation pages P1 to P3 with high operation frequency are different for each day of the week, the operation pages P1 to P3 with high operation frequency are specified for each time zone. If the page is designated, it is possible to save the trouble of switching the operation pages P1 to P3 after the screen display is resumed.

  In this embodiment, weekday, Saturday, and Sunday are illustrated as time zones in the schedule table. However, the time zone may be determined in units of one day with a period of one week. Whether to classify according to such rules is not limited to the above example.
