However, the equipment device controller 2, particularly the air conditioning equipment controller 2 a, may be embedded in the wall or installed behind the ceiling for each floor in the building.

FIG. 2 shows the configuration of the equipment control device applied to the building equipment management system shown in FIG. The equipment device group 1 shown in FIG. 2 represents one of the equipment devices group 1 (air conditioning equipment group 1a, lighting equipment group 1b) shown in FIG. The same applies to the equipment device controller 2, and the equipment device controller 2 shown in FIG. 2 is one of the equipment equipment controllers 2 (air conditioning equipment controller 2a, lighting equipment controller 2b) shown in FIG. This is representative.

The equipment device controller 2 includes equipment state monitoring means 9, average control necessity determination means 10, equipment group information storage means 11, control object determination means 12, and equipment control means 13.
The equipment state monitoring means 9 monitors the operating state of each of the plurality of equipment devices constituting the equipment device group 1. And it detects that the operating state of at least any one of the some installation apparatus which comprises the installation apparatus group 1 changed.

In addition, although illustration is abbreviate | omitted here, each equipment apparatus (air conditioning equipment and lighting equipment) which comprises the equipment equipment group 1 (the air conditioning equipment group 1a and the lighting equipment group 1b) is a switch for changing the operating state. Etc. are provided. The user of the facility equipment can change the desired facility equipment constituting the equipment group 1 to a desired operating state by operating the operation means.

When the equipment state monitoring means 9 detects a change in the operating state of the equipment, the average control necessity determination means 10 is a facility that constitutes the equipment group 1 to which the equipment that has detected the change in the operating state belongs. Determine whether the device needs to be controlled. The determination as to whether or not this control is necessary is performed based on the average operating state of the equipment that constitutes the equipment group 1 to which the equipment that has detected a change in the operating state belongs.

The equipment group information storage means 11 stores in advance a correspondence relationship to which equipment equipment group 1 each equipment installed in the building belongs. The average control necessity determination means 10 first refers to the correspondence stored in the equipment group information storage means 11, and the equipment to which the equipment whose operating state change is detected by the equipment status monitoring means 9 belongs. Group 1 is identified. Next, it is specified by referring to the correspondence stored in the facility group information storage means 11 which equipment is included in the specified equipment group 1. Then, based on the specified information, the operating state of each equipment device constituting the equipment device group 1 is acquired via the equipment state monitoring means 9.

Subsequently, the average control necessity determination means 10 calculates the average of the acquired operating states of the respective facility devices, so that the facility devices constituting the facility device group 1 to which the facility devices in which the change in the operating state is detected belong. Find the average operating condition. Then, the average control necessity determination means 10 compares the average operating state thus obtained with a predetermined reference value, thereby determining the facility device group 1 to which the facility device in which the change in the operating state is detected belongs. It is determined whether or not the facility equipment to be configured needs to be controlled.

When the average control necessity determination means 10 determines that it is necessary to control the equipment constituting the equipment group 1 to which the equipment in which the change in the operating state is detected belongs, the control target determining means 12 Determine the equipment to be controlled.

The equipment to be controlled is selected from the equipment constituting the equipment group 1 to which the equipment whose operating state has been detected by the equipment state monitoring means 9 belongs. At this time, however, the equipment for which the change in the operating state is detected by the equipment state monitoring means 9 is excluded from the target. Here, the priority order of the equipment to be determined as a control target may be determined in advance and stored in the equipment group information storage unit 11.

In the case of the air conditioning equipment group 1a, the priority order of the air conditioning equipment determined as the control target may be determined by the measured value of the indoor thermometer. Furthermore, in the case of the lighting equipment group 1b, the priority order of the lighting equipment determined as the control target may be determined based on the measurement value of the indoor illuminometer.

The facility control means 13 controls the operating state of the equipment in the equipment group 1 determined as the control target by the control target determination means 12. As a result of this control, the operation state control is such that the average operation state of each facility device constituting the facility device group 1 conforms to the reference value used for determination by the average control necessity determination means 10.

In the example described here, the operating state of the facility equipment group 1 is the lighting state of the lighting equipment group 1b, and the average of the equipment constituting the equipment device group 1 used for determination by the average control necessity determination unit 10 is used. A typical operating state is the lighting rate of the lighting equipment which comprises the lighting equipment group 1b.

First, in step S1, the equipment state monitoring means 9 confirms whether or not the lighting state of the lighting equipment of the lighting equipment group 1b has changed. When the lighting state of the lighting equipment has changed, the process proceeds to the next step S2. In step S2, it is confirmed whether or not the change in the lighting state of the lighting equipment in step S1 is lighting of the lighting equipment. When the change in the lighting state of the lighting equipment is not lighting off but lighting, the process proceeds to step S3. On the other hand, when the change in the lighting state of the lighting equipment is not lighting of the lighting equipment but off, the process returns to step S1.

In step S3, the average control necessity determination means 10 confirms whether or not the number of lighting fixtures constituting the lighting fixture group 1b to which the lighting fixture whose lighting state has changed in step S1 belongs is equal to or less than a specified value. . Here, the specified value can be calculated by multiplying the reference lighting rate by the total number of lighting equipments constituting the focused lighting equipment group 1b. Specifically, for example, when the lighting rate as a reference is 80% and the lighting equipment group 1b of interest is composed of 50 lighting equipments, the specified value is 40.

In this step S3, if the number of lighting of the lighting equipment constituting the focused lighting equipment group 1b is equal to or less than a specified value, the lighting rate of the lighting equipment constituting the focused lighting equipment group 1b is set as a reference lighting. Since it is less than the rate, the process returns to step S1. On the other hand, in step S3, when the lighting number of the lighting equipment which comprises the focused lighting equipment group 1b exceeds the regulation value, it progresses to step S4.

In this step S4, the control object determining means 12 determines the lighting equipment to be turned off from the lighting equipment group 1b of interest. At this time, the lighting equipment in which the change in the lighting state is detected in step S1 is excluded from the control target. By doing in this way, the situation where the lighting installation turned on by the user will be automatically turned off immediately after that can be avoided.

After step S4, the process proceeds to step S5. In this step S5, the equipment control means 13 turns off the lighting equipment determined as the target of the turn-off control in step S4. After step S5, the process returns to step S1.

In addition to confirming the lighting rate in the lighting equipment group 1b when any one of the lighting equipments is turned on as described here, the lighting rate in the lighting equipment group 1b is regularly checked every time a certain time elapses. Confirmation may be performed.

The equipment control apparatus configured as described above includes a monitoring unit that detects that the operating state of at least one of a plurality of equipment constituting the equipment group has changed, and the equipment by the monitoring means. When a change in the operating state is detected, the facility device group is configured based on the average operating state of each facility device that configures the facility device group to which the facility device in which the change in the operating state is detected belongs. Necessity determining means for determining the necessity of control of the equipment and the equipment constituting the equipment apparatus group when the necessity determining means determines that the control of the equipment constituting the equipment apparatus group is necessary. Among the devices, there are a control target determining means for determining a control target from equipment other than the equipment whose operating state is detected by the monitoring means, and a control target equipment determined by the control target determining means. And Gosuru control means is those with.

For this reason, when a user performs an operation that increases the power consumption for a certain equipment that constitutes the equipment device group, the power consumption in other equipment belonging to the equipment device group is reduced. Can be controlled automatically. Accordingly, it is possible to suppress an increase in power consumption in the entire equipment group before and after an operation by the user.

Based on the above, the necessity of each facility device is maintained without pre-setting the control conditions for each facility device, while keeping the power consumption of the entire facility device group within the specified range. Accordingly, it is possible to automatically perform control so that a facility device required by the user is operated and an unnecessary configuration device is not operated.

This will be specifically described using the example described in the first embodiment. For example, in a lighting equipment group composed of 50 lighting equipments, consider the case where the number of lighting equipments that are lit is 40 or less. In this case, when the lighting equipment is turned on by the user's operation and the number of lighting equipment turned on exceeds 40, lighting equipment other than the lighting equipment that was turned on immediately before is automatically turned off. . And every time the lighting state of the lighting equipment is changed by the user, it is necessary according to the situation at that time while keeping the number of lighting equipments turned on to 40 or less by performing such control. It is possible to automatically control lighting equipment to be turned on and unnecessary lighting equipment to be turned off.

For this reason, when a user changes a control target value that increases the power consumption of a certain equipment that constitutes the equipment device group, the power consumption of other equipment belonging to the equipment device group Can be automatically controlled so as to reduce. Accordingly, it is possible to suppress an increase in the power consumption of the entire equipment group before and after the change of the control target value by the user.

Based on the above, the necessity of each facility device is maintained without pre-setting the control conditions for each facility device, while keeping the power consumption of the entire facility device group within the specified range. Thus, it is possible to automatically perform control so that an appropriate control target value corresponding to is set.

This will be specifically described using the example described in the third embodiment. For example, let us consider a case where it is desired to set the average temperature of the air conditioning equipment to 20 ° C. or less in an air conditioning equipment group composed of 50 air conditioning equipment. In this case, when the set temperature of the air conditioning equipment is changed by the user and the average value of the set temperatures in the air conditioning equipment group exceeds 20 ° C., the setting of the air conditioning equipment other than the air conditioning equipment whose set temperature has been changed immediately before The temperature is automatically lowered. Each time the set temperature of the air conditioning equipment is changed by the user, such control is performed so that the average value of the set temperature of the air conditioning equipment is kept below 20 ° C. It can be automatically controlled to a state where the required set temperature is reached in the equipment.

In addition, the example given here is an example of keeping the power consumption within the specified range by setting the average value of the set temperature to a reference value or less when performing heating operation in winter. In addition to this example, for example, in the case of cooling operation in summer, it is also possible to keep the power consumption within a specified range by setting the average value of the set temperatures to a reference value or more.

The present invention can be used for, for example, a control device for equipment that controls the operating states and control target values of a plurality of equipment installed in a building or facility such as a building.
