Description

  The present invention relates to a centralized monitoring device for a cooling device that collectively controls illumination of a plurality of cooling devices.

A system that collectively manages lighting such as a plurality of showcases has been proposed (Patent Document 1).
In this proposed system, it is possible to set a plurality of point / light-off schedules composed of lighting times and light-off times of showcase lighting, and based on a schedule selected from the set point / light-off schedules. The lighting of the showcase is turned on and off. It has also been proposed to assign a turn-on / off schedule for calendar dates.
JP 2001-272161 A

In the proposed system above, multiple lighting / lighting schedules consisting of lighting time and lighting time are set in advance, and the lighting lighting time / lighting time is changed by selecting the lighting / lighting schedule. In the case of a closed day, it is necessary to set all changeover switches to the stop on the night before the closed day and to set the changeover switch to the corresponding point / light-off schedule the next morning after the closed day. For this reason, if the operator forgets to operate on the morning after the closed day, there is a problem that the lighting is not turned on.
In addition, it may be possible to register closed days in an annual calendar set in a system monitoring device that manages multiple showcases at the same time. Only the person who has can change the setting information, and there is a problem that the operation of the system monitoring apparatus is not easy.
In recent years, supermarkets and the like are often open 24 hours a day, and many stores are closed irregularly on special holidays such as the New Year for one or two days. There is a demand for a centralized monitoring device for a cooling device that can easily set a holiday according to such a business form.

The up key 3d and the down key 3e are the contents of the indicators 3a to 3c selected by the selection key 3f (for example, “00” to “23” when the selected indicator is 3a, “ In the case of “00” to “59” and 3c, the operation keys are used to select “on” or “oF”). The content displayed on the display 3a or 3b increases by one every time the up key 3d is operated, and decreases by one every time the down key 3e is operated.
The confirmation key 3g is an operation key for confirming the on time and off time of the schedule control selected by operating the selection key 3f, the up key 3d, and the down key 3e.

FIG. 4B is an enlarged view of the display / operation unit B (25).
As shown in the figure, the display / operation unit B (25) is provided with eight operation keys including schedule keys 4A to 4G corresponding to each day of the week from Sunday to Saturday and an all stop key 4H for designating all stops. Corresponding day-of-week indicators 4a to 4g and a stop indicator 4h are provided on the operation keys 4A to 4H, respectively. For example, LEDs are used as the day of week indicators 4a to 4g and the stop indicator 4h.

(Clock setting)
A method of setting the current time using the display / operation unit A (24) will be described.
When the time has never been set in the clock management unit 26 in FIG. 2, the hour indicator 3a blinks “00”. By selecting the current time “00” to “23” (hours) with the selection key 3f, up key 3d, and down key 3e and pressing the enter key 3g, the hour indicator 3a is continuously displayed, and then the minute The display 3b blinks “00”.
Subsequently, by selecting the current time “00” to “59” (minutes) with the selection key 3f, the up key 3d, and the down key 3e and pressing the enter key 3g, the minute indicator 3b is continuously displayed. The set time (hour, minute) is stored in the clock management unit 26. The clock management unit 26 is provided with a calendar timer and the like, and the time is counted even during a power failure by a battery or the like.
When time correction is necessary, for example, “08” may be assigned to the mode setting display 3c to set the time correction mode. The time setting method may be the same method as described above. Further, when the indicators 3a and 3b are displaying the time, the dot 3t of any of the indicators 3a and 3b may blink.
The day of the week can be set by pressing the schedule keys 4A to 4G corresponding to the day of the week and the confirmation key 3g simultaneously for a predetermined time (for example, 5 seconds).

(Schedule time setting)
The mode setting display 3c of the display / operation unit A (24) has numbers “1” to “7” (1: day, 2: month,..., 7: Saturday) indicating “day of the week”, “on "Or" oF "is displayed, but usually, any number from" 1 "to" 7 "indicating the day of the week is displayed.
When the mode setting indicator 3c is selected by pressing the selection key 3f of the display / operation unit A, “1” indicating Sunday is flashed on the indicator 3c.
At this time, by pressing the up key 3d or the down key 3e, "1" (day) to "7" (Sat) can be selected on the mode setting display 3c. Here, the day of the week ("1" (Sun) to "7" (Sat)) is confirmed by pressing the enter key 3g, and the indicators (4a to 4g) corresponding to the selected day of the week blink.
At this time, “on” is displayed blinking on the mode setting display 3c, and the set ON time is displayed on the hour display 3a and the minute display 3b. When the ON time data is not yet input, for example, only “.” (Dot 3t) of the hour display 3a and the minute display 3b is displayed. By pressing the up key 3d or the down key 3e in this state, it is possible to select “on” or “oF” on the display 3c.
When “on” or “oF” is blinking on the mode setting display 3c, the “on” or “oF” display is continuously lit by pressing the enter key 3g, and the mode is determined. Is done. When “on” is selected, the on-time setting mode is selected, and when “oF” is selected, the off-time setting mode is selected.
Here, when the mode is determined, the hour indicator 3a starts blinking. In this state, pressing the up key 3d or the down key 3e selects the hour ("0" to "23"), and pressing the confirm key 3g confirms the time (hour) of the mode. The indicator 3a is continuously lit, and then the minute indicator 3b flashes. The minutes ("0" to "59") are selected by pressing the up key 3d or the down key 3e in the same procedure as the time display 3a, and the schedule of the mode is pressed by pressing the confirmation key 3g. The time is fixed and stored in the storage unit 23.
In the same manner, the schedule time of the other mode (“on” or “oF”) can be determined.
When the predetermined setting for the corresponding day of the week is completed, the flashing of the indicator (any one of 4a to 4g) corresponding to the corresponding day of the week is turned off, and the set content is stored in the storage unit 23.

The determination unit 27, which is a schedule control means, compares the current time of the clock management unit 26 with the on time and the off time stored in the storage unit 23, and issues an illumination on command when the on time is reached. It transmits to each electronic controller 1 via the communication part 21, and transmits an illumination-off command to each electronic controller 1 when the off time comes.
Each electronic controller 1 performs lighting on / off control of the connected showcase 2 in accordance with the on command or the off command from the host control device 20.
When the schedule key 4H is pressed and the stop indicator 4h is lit, all schedule control is prohibited, and control is performed so that all the showcases 2 are turned off (the electronic controller 1 is turned off). Is sent).

In this embodiment, the operator can prohibit the schedule control ON control for a specific day of the week. Although details will be described later, when any of the schedule keys 4A to 4G is pressed, the indicators 4a to 4g corresponding to the pressed switches are turned on, and the schedule control of the day of the week when the indicator is lit is turned on. It is prohibited only once.
In addition to prohibiting the on-control of schedule control as described above, schedule control based on a specific schedule time set separately can be executed only once. For example, this is effective when it is desired to change the schedule time of a specific day of the week to a special schedule time due to a specific event.
For the special schedule time, for example, when any one of the schedule keys 4A to 4G is pressed, “on” or “oF” is displayed blinking for a predetermined time (for example, 5 seconds) on the mode setting display 3c. During the blinking display, as described above, “on” or “oF” is selected by the up key 3d or the down key 3e, and the schedule time setting operation is started. it can. The set special schedule time is stored in the storage unit 23 separately from the normal schedule time.

FIG. 5 is a diagram illustrating an example of a table referred to in the control process by the determination unit 27 in the present embodiment.
(A) of FIG. 5 is a calendar timer (C · T) provided in the clock management unit 26, and stores data of year, month, day, day of the week, hour, minute, and second, as shown in the figure. It is automatically updated. Here, the data of the day of the week represents Sunday to Saturday with numbers “1” to “7”. The “hour” and “minute” data are the current time in the schedule control.
FIG. 5B is a diagram showing an example of a day of the week pointer (WP) stored in the storage unit 22 and stores data “1” to “7” of the day of the week stored in the calendar timer. Is done. As will be described later, the data stored in the day of the week pointer (WP) is compared with the data of the day of the week stored in the calendar timer (C / T) of the clock management unit 26. The day of the week data stored in C · T of the clock management unit 26 is copied to the day of the week pointer.

FIG. 5C is a view showing an example of a 7-day schedule table (W · S · T) stored in the storage unit 23. As shown in this figure, in this embodiment, the normal schedule on time and off time, and the special schedule on time and off time are stored for each day of the week. Here, “-:-” indicates a null value (null), that is, the set time is not set. In the example shown in this figure, as normal schedules, the schedule time for lighting from 9:00 to 22:00 on Sunday, from 10 to 22:00 on Monday to Friday, and from 8:30 to 23:00 on Saturday Is set, and a special schedule time for lighting is set on Monday from 9:30 to 21:30.
The determination unit 27 refers to the schedule table and transmits an illumination on command and an illumination off command to each electronic controller 1.

The flow of schedule control processing by the control unit 27 in this embodiment will be described with reference to FIGS.
6 is a flowchart showing the flow of the schedule control process (weekly schedule control process) in this embodiment, FIG. 7 is a flowchart showing the flow of the weekly schedule on control process, and FIG. 8 is the flow of the weekly schedule off control process. It is a flowchart which shows.
The weekly schedule control process is activated when any one of the schedule keys 4A to 4G is pressed or every predetermined time (for example, 1 minute).
When the weekly schedule control process is started, first, the day of the week data stored in the day of the week pointer (WP) and the day of the week data stored in the calendar timer (CT) of the time management unit 26 (S11), and if they do not match, the day of the week data stored in the calendar timer (C · T) is copied to the day of the week pointer (W · P) (S12).
Next, it is determined whether or not any of the schedule keys 4A to 4G is pressed (S13), and if not, the process proceeds to the weekly schedule on control (S18).
When any one of the schedule keys 4A to 4G is pressed, the indicators 4a to 4g corresponding to the pressed switch are turned on (S14), and the day of the pressed switch is the day of the week pointer or the day of the week. It is determined whether or not it is equal to the day of the next day (S15). When the determination result is NO, the process proceeds to the weekly schedule on control (S18). On the other hand, when YES, that is, when the day of the pressed switch is the current day or the day after that, the current time is between the off time of the day before the pressed day and the on time of the pressed day. Is determined (S16). When the result is NO, the process proceeds to the weekly schedule on control (S18). When the result is YES, the display corresponding to the pressed switch lit in S14 is selected from the displays 4a to 4g. 4a-4g is made to blink (S17). Then, the process proceeds to the weekly schedule on control (S18).

FIG. 7 is a flowchart showing the processing contents of the weekly schedule on control (S18).
In this process, first, the schedule time is read from the 7-day schedule table (W · S · T) indicated by the day of the week pointer (W · P) (S20), and whether or not a special schedule is set on that day. Is determined (S21).
As a result, when a special schedule is set, it is determined whether or not the current time matches the on-time of the special schedule (S22). If not, the weekly schedule-on control is performed. The process ends. When the current time matches the on-time of the special schedule, the on-time of the special schedule for that day stored in the 7-day schedule table indicated by the day pointer is cleared (“-:-”). (S25), an illumination on command is transmitted to the electronic controller 1 (S26). Thereby, the illumination of the showcase 2 is turned on according to a special schedule.
On the other hand, when a special schedule is not set on the current day (S21 is NO), the process proceeds to step S23, and it is determined whether or not the indicators 4a to 4g corresponding to the current day are blinking. When the indicators 4a to 4g on the current day are not blinking, it is determined whether or not the current time matches the on-time of the normal schedule stored in the 7-day schedule table (W · S · T). If they match (S24), an illumination on command is transmitted to the electronic controller 1 (S26). Thereby, the illumination of the showcase 2 can be turned on according to a normal schedule.
Further, when the lighting of the day is flashing, this weekly schedule on control is terminated as it is. That is, the lighting on control is not performed.
After the weekly schedule-on control process (S18) is completed, the weekly schedule-off control process (S19) is executed.

FIG. 8 is a flowchart showing the flow of the weekly schedule off control process (S19).
In this process, first, it is determined whether or not a special schedule is set on that day (S27).
When a special schedule is set, it is determined whether or not the current time coincides with the special schedule off time (S28). If not, the weekly schedule off control process is terminated. To do.
When the current time matches the off time of the special schedule, clear the off time of the special schedule in the 7th day schedule table (WST) indicated by the day of the week pointer (WP) Then (rewritten to “-:-”) (S30), an illumination-off command is transmitted to the electronic controller 1 (S31). Thereby, the illumination of the showcase 2 can be turned off according to a special schedule.
Then, the corresponding display device (the display device that has been commanded to turn off the illumination, the display device that was blinking) is turned off from the display devices 4a to 4g (S32).
Next, it is determined whether or not the indicators 4a to 4g for the day corresponding to the next day are lit (S33). If there is a lit indicator, the indicator is changed to a blinking state (S34). . Then, the weekly schedule off control process ends.

On the other hand, when a special schedule is not set on the current day (S27 is NO), it is determined whether or not the current time matches the off time of the normal schedule for that day (S29).
As a result, when the current time coincides with the normal schedule off time, the process proceeds to step S31, where an illumination off command is transmitted to the electronic controller 1, and the corresponding display is turned off (S32). When the next day of week display is lit, the display is changed to a blinking state (S34), and the weekly schedule off control process is terminated.
If the current time does not coincide with the normal schedule off time (NO in S29), the weekly schedule off control process is terminated.

Next, such a weekly schedule control operation will be described based on a specific example.
FIG. 9A is a time chart for explaining a weekly schedule control operation when a special schedule is not set, and FIG. 9B is a time chart for explaining a weekly schedule control operation when a special schedule is set.
In FIG. 9A, it is assumed that the schedule key 4B (FIG. 4) corresponding to Monday is pressed at time (1) before the schedule control off time (22:00) on Sunday. At this time, S13 in FIG. 6 is YES, and the display 4b corresponding to the pressed schedule key 4B is turned on (S14). Since the day of WP is Sunday “1”, the determination result in S15 is YES, but since the current time is before the off time (22:00) the day before the pressed day, the determination result in S16 Becomes NO. Next, the weekly schedule-on control process (S18, FIG. 7) and the weekly schedule-off control process (S19, FIG. 8) are executed. S21 is NO, S23 is NO, S24 is NO, and S27 is NO and S29 become NO, and the state is continued as it is.
Similarly, when the weekly schedule control process is repeatedly executed and the current time is the normal schedule off time (22:00 on Sunday), step S29 in FIG. 8 is YES and the illumination of the electronic controller 1 is turned off. A command is transmitted (S31), and the illumination of the showcase 2 is turned off. Further, although S32 is executed, since there is no display corresponding to the illumination off command in the displays 4a to 4g, no display is turned off by this S32. Then, since the display 4b for the next day of the week (Monday) is lit, this is changed to blinking display (S33, S34). That is, at the time of (2), the Monday indicator 4b is changed to blinking display. Thereby, it is displayed that the ON control of the schedule control on Monday is prohibited.

Next, when the current time is 0:00 on Monday, the day-of-week data of the day-of-week pointer (WP) and the day-of-week data of the calendar timer (C / T) of the clock management unit 26 are inconsistent. The day of the week data of the calendar timer (C · T) is copied and updated to the day of the week data of the day of the week pointer (WP), that is, rewritten to “2” of Monday.
After that, the current time becomes the schedule control ON time (10:00) on Monday, but since the display of the day is in a blinking state, the result of S23 is YES. There is no transmission and no on-control is performed.
When the time has elapsed and the current time is the schedule control off time (3) (22:00) on Monday, the determination result in S29 of FIG. 8 is YES, and an illumination off command is transmitted to the electronic controller 1 (S31, Since the illumination is not turned on, nothing is actually executed.) The corresponding indicator (the blinking Monday indicator 4b) is turned off (S32). As a result, it is displayed that the prohibition of the on-control of the schedule control for the day is released. Then, it is determined whether or not the display of the next day of the week (Tuesday) is lit (S33). However, in this example, since it is not lit, the process of this time is ended as it is.
As described above, when any one of the schedule keys 4A to 4G is pressed, any one of the displays 4a to 4g corresponding to the pressed switch is turned on, and the schedule control of the day of the week when the display is lit is performed. On-control is prohibited only once.

FIG. 9B shows that when a special schedule time is set, on / off control of the schedule control is executed only once at the special schedule time instead of prohibiting the on control of the schedule control. Is the case. The special schedule time is deleted by executing the schedule control, and thereafter, the control returns to the normal schedule time control.
As described above, when 4B of the schedule keys 4A to 4G is pressed and within the predetermined time (for example, while the mode setting display 3c is blinking for about 5 seconds), the same operation as the setting operation of the schedule time described above is performed. It can be performed by setting the on time and off time of schedule control as special schedule times by operation. If no key operation is performed within the predetermined time, the control operation prohibits the on-control of the schedule control of the day as shown in FIG. 9A. In this case, the weekly schedule table (WST) has a special schedule time on Monday at 9:30 and off time at 21:30 as in FIG. 5C. Is set.

In this state, it is assumed that the Monday schedule key 4B is pressed at time (1) between the on time and the off time on Sunday. As a result, the Monday indicator 4b is turned on in S14, as described above. Then, as described above, when the Sunday schedule off time (2) (22:00) is reached, the Monday indicator blinks (S34).
When it is Monday and the current time is the special schedule on time (9:30) (YES at S22), the special schedule on time for that day of the weekly schedule table is cleared (S25), An illumination on command is transmitted to the electronic controller 1 (S26). Thereby, the illumination of the showcase 2 is turned on by the on time of the special schedule set on Monday.
When the special schedule off time (21:30) is reached (YES in S28), the special schedule off time in the weekly schedule table is cleared (S30), and an illumination off command is transmitted to the electronic controller 1. (S31), the corresponding display (4b) is turned off (S32). Thereby, the illumination can be turned off at a special schedule off time. In addition, since the special schedule on time and off time are cleared by S25 and S30, control based on the normal schedule time is performed on the next Monday.
When the normal schedule off time (22:00) on Monday is reached, the special schedule has already been deleted, so S27 in FIG. 8 is NO, S29 is YES, and the processing from S31 onward is executed. However, since the illumination of the showcase 2 has already been turned off and the display device has also been turned off, no processing is actually performed.

In the example of FIGS. 9A and 9B, the case where only one schedule key (Monday schedule key 4B in the above example) is operated has been described. It is apparent from the flowcharts of FIGS. As described above, when the schedule keys for a plurality of days of the week are operated, the same processing is performed for each day of the week.
In the above description, it has been described that the lighting of the showcase 2 controlled by the schedule control is one (shelf lighting). Usually, the showcase 2 has two lightings, shelf lighting and a work lamp (canopy). There are different types of lighting.
This work light can be executed by the schedule control together with the shelf lighting. For example, when the work light is controlled by the schedule control together with the shelf lighting, the work light is first turned on before the predetermined time (for example, 30 minutes) of the schedule control on time, and then the shelf lighting is performed at the on time. On-control is executed. Further, the off control of the schedule control may be a mode in which the off control is first executed on the shelf lighting at the off time, and the control for executing the off control on the work light after a predetermined time (for example, 30 minutes) may be added.
As another control mode, schedule times for work lights and shelf lighting may be stored independently so that independent schedule control can be executed.

  In the embodiment described above, an area for storing the on-time and off-time of the special schedule is provided in the 7-day schedule table (W · S · T) ((c) of FIG. 5) of the storage unit 23, When a special schedule is stored when the normal schedule control is prohibited, the schedule control is executed according to the special schedule. However, the on-time and off-time of the special schedule are set in the 7th day schedule table. A function for executing a special schedule may be omitted without providing a storage area.
