In the home bus system configured as described above, in many cases, this system is used by a plurality of persons, so that one person uses one terminal device. During the operation, there is a problem that the use is stopped by the control of the home controller without knowing that the other person is using. For example, when one person is using the toilet and turning on the lights, the other person determines that the whole family is going to bed, and the home controller uses the bed control mode (pattern control) to turn on all of the set lights and the like. That's what cuts are all about.

[0008] As described above, it is good to avoid turning off the toilet while in use, but there is a problem that if the user turns off the light after use, the lighting of the toilet remains on.

It is characterized by having.

[0014] Further, there is provided optional setting means for arbitrarily setting a terminal device which can be centrally controlled by the home controller from among terminal devices in a room in which the presence of a person has been detected by the human body detecting means. And

[0015] Then, a plurality of terminal devices installed in a plurality of rooms in the home are connected to a home controller for centrally controlling the terminal devices via a home bus which is a home information transmission path. In a home bus system configured to centrally control devices by the home controller, a human body detecting unit for detecting the presence of a person in each of the rooms is provided, and the human body detecting unit is connected to the home controller via the home bus. In addition to the above, the home controller is provided with storage means for storing the content of centralized control, and timer means having a timer function,
When centralized control is performed by the home controller, central control by the home controller is not immediately performed on terminal devices in a room in which the presence of a person has been detected by the human body detection unit, but the terminal device is concentrated on the storage unit. When the absence of a person is detected by the human body detection means, or immediately after the elapse of a predetermined time set in the timer means, the content of the control is stored in accordance with the content of the centralized control stored in the storage means. The apparatus is characterized in that the apparatus is controlled.

Comparing means for comparing the time zone of the centralized control set by the time zone setting means with the home controller; When the medium control is performed, the central control by the home controller is not immediately performed on the terminal device in the room in which the presence of a person is detected by the human body detection unit, and the content of the central control is stored in the storage unit. Then, when the absence of a person is detected by the human body detecting means, the comparing means compares the current time of the clock means with the time zone of the centralized control set by the time zone means, and When the determination is made, the contents of the centralized control stored in the storage means are executed.

Also, a plurality of terminal devices installed in a plurality of rooms in the home are connected to a home controller for centrally controlling the terminal devices via a home bus which is an in-home information transmission path. In a home bus system in which a room controller that controls the terminal device for each room is connected to a home bus, the room controller performs priority control of the terminal device installed in the room where the room controller is located. A priority control setting means for setting is provided, and by setting the priority control by the priority control setting means, the terminal equipment in the room where the room controller is placed is excluded from the centralized control by the home controller. It is characterized by the following.

When a time period for centralized control is set and the absence of a person in the room where centralized control is suspended is detected,
The current time of the clock means is compared with the time zone of the centralized control, and if the current time is the time zone of the centralized control, the terminal device is controlled by the content of the centralized control stored in the storage means. It is possible to eliminate forgetting to turn off the lighting.

Further, since each room is provided with a room controller capable of controlling the terminal equipment of the room prior to the home controller, the control of the terminal equipment of each room is performed prior to the centralized control of the home controller. Can be set by the controller. This setting can be instructed from the operation unit on the home controller side or from the operation unit on the room controller side. Therefore, when the room controller-side priority control is set, the control by the operation unit on the home controller side does not reach the terminal device for which the device-side control priority is set, and the control on the terminal device side has priority. Therefore, even in the case where central control for turning off a plurality of terminal devices simultaneously by the home controller is performed, terminal devices for which device-side control priority is set can be excluded from the control.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing the embodiments. FIG. 1 is a schematic configuration diagram showing one embodiment of the home bus system of the first invention, and FIG. 2 is a flowchart showing a processing procedure of the home bus system shown in FIG.

In FIG. 1, a home bus 1 installed in a home is an information transmission line composed of a coaxial cable and a twisted pair cable.
(Hereinafter referred to as HC2). An information outlet 3 is arranged at a key point of the HC2,
Each terminal device T1, T2, T3,.
Is connected. Further, the human body detecting means 8 (in this embodiment, the presence of a person is detected by detecting the fluctuation of far-infrared rays emitted by the human body with a pyroelectric infrared sensor.
As another method, when there is a partition as a room, an object detection sensor by an interrupt may be provided at the entrance, and a person may detect a person entering or exiting by blocking a light beam of the interrupt. ) Also the above information outlet 3
It is connected to the.

The IFU 9 inserted between the terminal device T and the human body detecting means 8 and the information outlet 3 is
An interface unit for matching the terminal device T and the human body detecting means 8 with the home bus 1. Further, a security sensor 4 such as a smoke sensor, a security sensor, and a gas sensor, and an environment sensor 5 such as a temperature sensor and a humidity sensor are connected to the home bus 1.
2.

The above-mentioned HC2 connects each terminal device T to each room 10
Each of the rooms 10 is provided with a human body detecting means 8. And the HC2
In addition to performing on / off control of each terminal device, it also performs status monitoring and performs control based on environmental conditions or external input signal information, and also controls based on input signal information from each terminal device. I do. In addition, for the abnormal information from the security sensor 4, an alarm, a report, and the like are executed. Further, it plays a central role in the present system having functions such as an interface with NT (network termination). NT1 corresponds to a television or radio broadcast antenna. NT2 is a two-way communication network, and is usually a CATV termination device. NT3 is a public network terminal, which is usually connected to a telephone line.

In the home bus system configured as described above, it is possible to perform house control for performing automation, monitoring control, and the like of home electric appliances and house equipment. For example, on / off control for remotely turning off lighting, air conditioning, and the like of a room that is not being used from the HC2, or controlling the air conditioning to operate at a comfortable time by using the air conditioning for a predetermined period of time, and in accordance with environmental conditions. Control for switching energy sources such as gas, electricity, solar heat and energy saving operation,
This includes control for crime prevention and disaster prevention using a smoke sensor, security sensor, earth leakage sensor, and the like.

As described above, since the terminal device T can be turned on / off from the HC2, for example, during bedtime, pattern control in which unnecessary lights are collectively turned off except for gate lights, entrance lights, etc. (For example, it is set so that the gate light and the entrance light are left in one key, and other lights are collectively turned off, and the centralized control is performed by pressing one of the set keys.) be able to.

However, when the system is used by a plurality of persons, when the collective turn-off is executed for going to bed as described above, the collective turn-off operation is performed even though one person is in use. A person who turns off the light may not notice it. In order to prevent such adverse effects, a detection signal is sent to the HC 2 from the human body detection means 8 for each room, and when there is a person in that room,
There is provided a means for setting the HC 2 so as not to control the terminal device T in the room. When a person is present in a room, if the terminal device T in the room is set not to be controlled, the terminal device is excluded from the centralized control by the operation unit on the HC2 side, and is excluded from the above-mentioned collective turning off or the like. Become.

The HC2 is provided with means for arbitrarily setting a terminal device T capable of performing centralized control from the HC2 even when there is a person in the room. Therefore, when a person is present in a room, all terminal devices T in that room
The terminal device T that has been set can perform centralized control instead of centralized control.

For example, if the skylights are set so that they can be centrally controlled, the HC2 can automatically perform centralized control according to environmental conditions to open and close the skylights regardless of the presence or absence of a person in the room. . Alternatively, when the security sensor 4 operates to detect a fire, the lights in all the rooms can be turned on and an alarm can be sounded to notify the occurrence of an abnormality.

The processing procedure for setting and controlling the control restrictions of the terminal device will be described with reference to the flowchart shown in FIG. S1 to S10 shown in FIG. 2 indicate the order of steps in the processing procedure.

First, in steps S1 to S4, the contents and conditions of exception pattern control that can be centrally controlled from the HC2 in a room where a person is present, and the terminal equipment T to be excluded from the setting for not performing centralized control are set. Next, in step S5, if there is an instruction to perform centralized control on HC2, step S5 is executed.
At 6, it is determined whether or not exceptional pattern control is set. If the exceptional pattern control is set, the process proceeds to step S9 to control the terminal device T, displays the control result on the display unit of the HC2 in step S10a, and ends a series of operations.

If it is determined in step S6 that the exceptional pattern control is not set, it is determined in step S7 whether or not there is a person in the room of the terminal device T controlled by the signal from the human body detecting means 8. When there is no person in the room, the process proceeds to step S9. Then, when there is a person in the room, it is determined in step S8 whether or not the terminal device T to be controlled is set to be excluded from the devices set out of the target of the centralized control.

If the above exclusion setting has been made, the process proceeds to step S9. In step S8, when the setting for exclusion is not made, the terminal device T is not controlled, and in step S10, it is displayed on the display unit of the HC2 that there is a person in the room and the centralized control cannot be performed. To end.

In step S26, NO, that is,
If the lighting in the room has not been turned off, the process proceeds to step S27, where an instruction to turn off the light is issued via the home bus 1, and the lighting is turned off.

FIG. 7 is a schematic diagram showing an embodiment of the home bus system according to the fourth invention. In FIG. 7 above,
A home bus 11 installed in a home is an information transmission line including a coaxial cable and a twisted pair cable, and a home controller 12 (hereinafter, referred to as an HC 12) is connected to one end of the information bus. An information outlet 13 is arranged at a key point of the HC 12, and the terminal devices T11, T12, T13,... Are connected to the information outlet 13. The room controller 18 is also connected to the information outlet 3.

Then, an IF inserted between the terminal equipment T and the room controller 18 and the information outlet 3
U19 is an interface unit for matching the terminal device T and the room controller 18 with the home bus 11. Further, the home bus 11 has a smoke sensor,
Security sensors 14, such as security sensors and gas sensors,
And an environment sensor 15 such as a temperature sensor and a humidity sensor, and transmits detection information to the HC 12.

The HC 12 connects each terminal device T to each room 2
The setting is made so as to recognize every 0, and the room controller 18 is also provided for each room 20. The HC 12 performs on / off control of each terminal device and the like, performs state monitoring to perform control based on environmental conditions or external input signal information, and performs control based on input signal information from each terminal device. Performs control. In addition, for the abnormality information from the security sensor 14, an alarm, a report, and the like are executed. Further, it plays a central role in the present system having functions such as an interface with NT (network termination). NT11 corresponds to a television or radio broadcast antenna. NT12 is a two-way communication network, and is usually a CATV terminator. NT13 is a public network terminal, which is usually connected to a telephone line.

In the home bus system configured as described above, it is possible to perform house control for performing automation, monitoring control, and the like of home electric appliances and house equipment. For example, on / off control for remotely turning off the lighting, air conditioning, and the like of a room that is not being used from the HC 12 or control such as turning on the air conditioning for a predetermined period of time to bring the temperature to a comfortable temperature during use, or in accordance with environmental conditions. Control of switching energy sources such as gas, electricity, solar heat and energy saving operation, crime prevention by smoke sensor, crime prevention sensor, earth leakage sensor, etc.
This is control for disaster prevention.

As described above, since the terminal device T can be turned on / off from the HC 12, for example, during bedtime, pattern control in which unnecessary lights are collectively turned off while leaving gate lights, entrance lights, etc. (For example, it is set in advance so that the other lights are collectively turned off while leaving the gate light and the entrance light in one key, and the collective control is performed by pressing the set one key.) be able to.

However, when the system is used by a plurality of persons, when the collective turn-off is executed for going to bed as described above, the collective turn-off operation is performed even if one person is in use. A person who turns off the light may not notice it. In order to prevent such adverse effects, the HC 12 includes a room controller 1 for each room.
8 is provided, and priority control setting means is provided, in which control of the terminal device T in the room has priority over control from the room side. Therefore, when the priority control is set, the terminal device T in the room is excluded from the target of the centralized control by the operation unit on the HC 12 side, and is not the target such as the collective turning off as described above. Further, even if the room controller 18 sets a priority control for the terminal device T, the HC 12 has a means for selecting a terminal device T from the terminal device T and performing centralized control from the HC 12 side. Is provided. Therefore, even when the priority control is set, the centralized control of all the terminal devices T in the room cannot be performed from the HC 12, and the terminal devices T are excluded from the terminal devices T which are not set as the targets of the centralized control. The terminal device T
Centralized control is possible.

FIG. 8 shows the exception pattern control setting, the exclusion device setting, and the like during the centralized control of the home bus system shown in FIG.
9 is a flowchart showing a control processing procedure. FIG.
The control procedure will be described.

In steps S31 to S34 of FIG.
In a room where a person is present, the contents and conditions of the exception pattern control that can be centrally processed from the HC 12 and the terminal devices T to be excluded from the settings that are not subjected to the centralized control are set.

Next, at step S35, the HC12
If there is an instruction to perform centralized control, the process proceeds to step S36, and it is determined whether or not an exception pattern / condition is set. If the exception pattern condition has been set, the process proceeds to step S39, where the control of the terminal device T is performed. In step S40a, the control result is displayed on the display unit of the HC 12, and a series of operations ends.

If the exception pattern / condition is not set in step S36, it is determined in step S37 whether the room controller 18 of the room where the terminal equipment T to be controlled is installed is set to the priority control. to decide. If the priority control is not set, the process proceeds to step S39. When the priority control is set, it is determined in step S38 whether or not the terminal device T to be controlled is set to a device excluded from the target of the centralized control, and the terminal device T is excluded from the target of the centralized control. If the device has been set, the process proceeds to step S39,
When the terminal device T is not excluded from the target of the centralized control, the control of the terminal device T is not performed.
A display indicating that centralized control cannot be performed because priority control is set is displayed on the display unit 12, and a series of operations is ended.

FIG. 9 is a flow chart showing a procedure in which the home controller makes a priority setting of device control for each room from the home controller in the home bus system shown in FIG. 7, and the flow chart shown in FIG. A processing procedure for setting the priority control will be described.

First, in step S41, it is determined whether or not it is necessary to set priority control for each room. When setting the priority control, the process proceeds to step S42, where the room controller 18 of the room to be set is designated. Then, step S4
In 3, the terminal device T in the room to which the priority control is set is excluded from the target of the centralized control from the HC 12. And
In step S44, the room for which the priority control has been set is displayed on the display unit of the HC 12.

On the other hand, when canceling the priority control, the priority control is canceled by designating the room controller 18 of the room to be canceled in step S45, and is incorporated in the centralized control of the HC 12 in step S46. In, the display of the priority control is deleted.

In the above-described processing procedure, the case where the centralized control is performed by the HC 12 has been described. However, when a sub-controller is installed in the home bus system, the same terminal device is used when the centralized control is performed from the sub-controller. It is effective to perform the processing procedure for setting and controlling the control restrictions.

[0064]

Since the home bus system of the present invention is constructed as described above, when centrally controlling terminal equipment in another room by a home controller or the like, if there is a person in the room, the home bus system is It can be set so that control cannot be performed. In addition, a terminal device that can perform centralized control even when a person is in the room and a terminal device that does not allow centralized control can be set. Therefore, even when the home controller performs a pattern control for turning off a plurality of terminal devices simultaneously, terminal devices that do not allow centralized control of a room where a person is present are excluded from the control.

Further, in the case of the pattern control / condition from the home controller set in advance, it is possible to centrally control the terminal equipment which is not controlled in the room where the person is located. Even in the case of a terminal device that does not allow centralized control of a room, in the case of a fire or the like, it is possible to perform pattern control of simultaneously turning on the lighting.

Further, according to the second invention, when the absence of a person in the room where the centralized control is suspended is detected, the terminal on which the centralized control is suspended is determined according to the contents of the centralized control stored in the storage means. Since control of the device is performed, forgetting to turn off the lighting can be eliminated.

According to the third aspect of the present invention, the time zone of the centralized control is set, and when the absence of the person in the room where the centralized control is suspended is detected, the current time and the time zone of the centralized control are determined. In comparison, if it is within the time zone, centralized control of the suspended terminal device is performed in accordance with the content of the centralized control stored in the storage means, so that useless use of lighting or the like can be prevented.

Further, according to the fourth invention, when centrally controlling terminal equipment in another room by a home controller or the like,
With the room controller, the terminal device in the room can set priority control that gives priority to control in the room. This setting can also be instructed by the operation unit on the home controller side. When priority control that gives priority to control in the room is set, central control on the home controller side
The control of the terminal devices in the room has priority over the terminal devices in the room for which the priority control is set.

Further, even in a room where priority control is set, a terminal device that can perform centralized control and a terminal device that does not allow centralized control can be set. Therefore, even when pattern control for simultaneously turning off a plurality of terminal devices by the home controller is performed, terminal devices that do not allow centralized control of a room for which priority control is set are excluded from the control.

As described above, contrary to the convenience of centrally controlling everything from the home controller, the adverse effect of unilateral control is eliminated by the present invention by setting the priority of control on the terminal device side as needed.
