Description

[Detailed Description of the Invention] [Summary] The present invention is a time schedule operation system for equipment in a building such as a building management system, in which the operation time data of the equipment is created for each scheduled operation group, and the operation of the equipment is controlled for each equipment. Using the provided control request counter, the status value given from the operation time data is added or subtracted every time elapsed, and the operation is performed according to the result.When the operation time data is changed, the operation control of equipment belonging to multiple groups is performed. This makes management easier.

[Industrial application field]

The present invention relates to an improvement in a time schedule operation system for equipment.

For example, in scheduled operation in a building, the lights and air conditioning equipment in each room are operated according to a certain schedule for each room, and devices belonging to a certain room are treated as one group and are usually controlled to start and stop. .

However, within a group, there are devices such as electric lights that can be controlled without being related to other groups, and devices such as air conditioners that are related not only to the group but also to multiple groups. When there is a request to change the operating time data of such equipment, it is desired to provide an operating system that can easily implement the change.

[Conventional technology]

In conventional building management systems, when there is equipment that is shared between multiple groups, the shared equipment is considered as one independent group, and the earliest startup time among the multiple groups is given as the startup time. , the operation time is set using the stop time of the latest stop group as the stop time.

FIG. 4 is a simple block diagram showing an example of the equipment configuration to be operated on a schedule, FIG. 5 is a line diagram showing an example of operation time setting, and FIG. 6 is a diagram showing the schedule operation process for each group.

In Figure 4, 1 is room A, 2 is room B, 3 is the air conditioner,
Room A has electric light 1-1.1-2, -1 Room B' has electric light 2.
-1.2-2, - etc. are equipped with equipment to be operated on a schedule. The air conditioner 3 is shared by rooms ^ and B.

In FIG. 5, room A has electric lights and an air conditioner as equipment, and is started at 8:10 a.m. and stopped at 16:55.

Furthermore, room B is equipped with electric lights and an air conditioner as equipment, and these equipments are started at 8:10 and stopped at 21:10.

In Fig. 6, the schedule operation group is divided into three common groups, room ^, section MB1, indicated by group names.For example, room A consists of the components of light 1-11-2-, and the common group It consists of an air conditioner 3.

Each group is based on the time settings shown in Figure 5. The group to the room starts at 8:10 and stops at 16:55, and the group in room B starts at 8:10 and stops at 21:10. For the common group, a scheduled operation process of starting at 8:01 o'clock and stopping at 21:01 o'clock is determined.

Here, the schedule of the common group is determined by the earliest starting time in the group, 8:10 o'clock, and the latest stopping time in the group, that is, 21:10 for room B, as described above.

For example, in a building management system, the operating time period determined by the start and stop times described above is managed by a building manager.

[Problem that the invention seeks to solve]

As mentioned above, in the conventional scheduled operation method, equipment that is used jointly between groups becomes an independent group, and the setting of the operation time is determined by the administrator checking the operation time for all groups that are jointly used. After that, it must be done.

However, for example, when there are a huge number of scheduled operating groups, such as in modern high-rise buildings, it is extremely time-consuming for building managers to check the operating times of all groups and manage the operating times of common equipment. be. This becomes impossible to deal with, especially when the usage time changes constantly for each group.

In addition, the conventional scheduled operation method uses simple operation pattern,
For example, the operation pattern on -day is only a single on-off operation, but there is no operation pattern that repeats multiple on-off operations, making detailed operation impossible and making efficient operation impossible. There is a problem.

[Means for solving problems]

The problem mentioned above is that each schedule operation group 7° has operation time data for the group's constituent devices.

In addition, a control request counter is installed for each device, and according to the passage of time of the reference clock, 1 or -1 is added to the control request counter according to the device operating state from the operation time data, and scheduled operation is performed based on the result. This problem is solved by the time-scheduled operation method of the equipment according to the present invention, which is configured to perform the following steps.

[Effect]

According to the present invention, the operation time data of the component equipment is set for each schedule operation group including common equipment, and the control request counter provided corresponding to each equipment is The system counts the set operating time data and controls the operating status of each device according to the time, so the administrator does not have the ability to set special operating times for common devices, and can control the operation of devices. Since this is done flexibly, efficient schedule operation is possible.

〔Example〕

The gist of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the equipment schedule operation method according to the present invention, FIGS. 2(a) and 2(b) are detailed diagrams of scheduled operation data and a control request counter, and FIG. 3 is a diagram of a control request counter. A state transition diagram is shown.

In the figure, 4 is a reference clock, 5 is scheduled operation time data, 6 is a search means, 7 is a control request counter,
8 is a start/stop means; 9 is a control request counter provided corresponding to each device provided in the control request counter 7; 10 is a flag for indicating that control has been completed; 11.12 is a device that is shared especially between groups; The air conditioner control request counter and control completed display flag are shown.

In Fig. 1, schedule operation time data is stored in a non-volatile memory, and its details are as shown in Fig. 2 (a).
Operation time data is specified for each component within the group.

The search means 6 uses the search program as the reference clock 4.
The clock is activated, for example, at -minutes, and the current time is compared with the time of the scheduled operation time data 5.

As a result of this comparison, if there is a device to be activated at the current time, one is added to the control request counter 9 or 11 provided corresponding to the device in the control request counter 7.

Further, if there is a device to be stopped, 1 is subtracted from the control request counter provided corresponding to the device. If the control request counter is already 0, it is not subtracted.

As shown in FIG. 2(b), the control request counter 7 has a controlled flag 10.12 corresponding to the device, and this flag consists of a pair of an OFF ON flag and an OFF OFF flag. is always O.

The on flag can be 1 when the control request counter 9 or 11 is 1 or more, and the off flag can be 1 when the control request counter 9 or 11 is 0.

The start/stop means 8 includes a start/stop program, which is started by the search program of the search means 6.

The start/stop means checks the control request counters of each device one by one, and determines the following two conditions: i) the control request counter has a count value of 1 or more, and the on flag is 0, and it) the operation of the device is off. When the above is satisfied, the corresponding device 1-1-
Outputs an on signal to 13 etc.

Also, when the following two conditions are met: i) the control request counter is 0 and the off flag is O, and ii) the device is in the on state, the device 1-1 =
Outputs an off signal for the 3rd class.

When the start/stop means 8 outputs an on signal to a device, it clears the off flag of the device.

Also, if an off signal is output, the on flag is cleared.

FIG. 3 shows the transition states of the control request counters 9.11 and controlled flags for the device 1-1 electric light, device 2-1 electric light, and device 3 air conditioner, and each device is operated according to scheduled operation time data.

When the operation starts at 8:10, the control request counter 9
．． 11 counts 1 at this time, but the counter 11 for the equipment 3 air conditioner, which is shared between the groups, is counted from the two groups of room A and room B, so it becomes 2.

When each device is started, that is, turned on via the start/stop means 8, the controlled flag 10.12 becomes 0 as the off flag is cleared.
Therefore, the on flag becomes 1.

When the time reaches 16:55, based on the driving time data,
Since it is the stop time for the device 1-1 electric light and the device 3 air conditioner to the room, 1 is subtracted from the control request counter 911 of the device. That is, the counter becomes 0 for the electric light 1-1, and 1 for the air conditioner 3.

The start/stop means 8 stops the electric light 1-1 and clears the ON flag of the controlled flag 9. However, regarding the air conditioner 3, since the control request counter 11 does not become O but remains 1, no change is given to the controlled flag 12.

Next, when the time reaches 21:40, in the group of room B, the electric light of device 2-1 and the air conditioner of device 3 reach the stop time, and 1 is subtracted from the control request counter of the device. As a result, both counters 911 become O.

Therefore, the start/stop means 8 turns off the electric light 1-1 and the air conditioner 3, that is, stops them, and clears the ON flag of the controlled flag 1012 of the device.

According to the embodiment of the present invention, the controlled flag can prevent unnecessary on/off signals from being output to the device. That is, after turning on the output at 8:10, it is possible to prevent the output from turning on at 8:11.

〔Effect of the invention〕

As described above, according to the present invention, it is easy to manage the operation of equipment that is used redundantly between groups, and even when there is a change in operating hours between groups, it is easy to change schedule operation time data. be.

Furthermore, when organizing each group, it is possible to divide the groups according to the purpose of the equipment, and for example, it is possible to configure the system so that the operating status of equipment in a building can be easily grasped intuitively.

Furthermore, shared equipment that is used repeatedly is often turned on and off repeatedly due to irregular usage times, but according to the method of the present invention, it is possible to deal with this flexibly.
Its effects are extremely remarkable, such as making the scheduled operation of equipment extremely efficient.
