(Hereinafter referred to as HC2) is connected. And, the information outlet 3 is arranged at a key part of the HC2,
Each terminal device T1, T2, T3 ...
.. are connected. Further, the human body detecting means 8 (in this embodiment, a pyroelectric infrared sensor detects the fluctuation of far infrared rays emitted by the human body to detect the presence of a person.
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 block the light beam of the interrupt to detect the entrance and exit of the person. ) Is also the 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 smoke sensor, a crime prevention sensor, a security sensor 4 such as a gas sensor, and an environment sensor 5 such as a temperature sensor and a humidity sensor are connected to the home bus 1, and the detection information is stored in the HC.
2 is transmitted.

In the above HC2, each terminal device T is connected to each room 10
The human body detection means 8 is also set for each room 10 so as to be recognized for each room. Then, the above HC2
In addition to performing on / off control of each terminal device, it also performs state monitoring to control based on environmental conditions or external input signal information, and control based on input signal information from each terminal device. I do. In addition, with respect to the abnormality information from the security sensor 4, an alarm, a notification, etc. are executed. Furthermore, it plays a central role in this system, which has functions such as an interface with NT (Network Termination). NT1 corresponds to a television or radio broadcasting antenna. NT2 is a two-way communication network and is usually a CATV terminating device. NT3 is a public network terminating device, 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 automating and monitoring control of home electric appliances and household appliances. For example, on / off control to turn off lighting and air conditioning in an unused room from the HC2 by remote control, or to control the air conditioning from a predetermined time before it reaches a comfortable temperature according to environmental conditions. Control for switching energy sources such as gas, electricity, and solar heat, and for energy-saving operation,

Since the terminal device T can be controlled to be turned on / off from the HC 2 as described above, for example, at bedtime, pattern control in which unnecessary lights are collectively turned off while leaving gate lights, entrance lights, etc. (For example, the gate light and the entrance light are left in one key in advance and the other lights are collectively turned off, and the centralized control is performed by pressing the set one key.) be able to.

However, in the case where a plurality of people are using the system, when the collective extinguishment is performed for sleeping as described above, the operation of extinguishing the collective extinction is performed even if one person is in use. It happens that the person who turns off turns off the light without noticing it. In order to prevent such an adverse effect, the detection signal from the human body detecting means 8 is sent to the HC 2 for each room, and when there is a person in that room,
HC2 is provided with means for setting so as not to control the terminal device T in the room. When there is a person in the room, if it is set not to control the terminal device T in the room, it is excluded from the target of the centralized control by the operation unit on the HC2 side, and is excluded from the above-described batch extinction. Become.

Further, the HC 2 is provided with means for arbitrarily setting the terminal device T capable of performing centralized control from the HC 2 even when there is a person in the room. Therefore, when there is a person in the room, all the terminal devices T in the room are HC2
It is not possible to perform centralized control from above, but the set terminal device T can perform centralized control.

For example, if the skylight is set to be able to be centrally controlled, the HC2 can automatically perform the centralized control according to environmental conditions to open and close the skylight regardless of the presence or absence of a person in the room. .. Alternatively, when the security sensor 4 operates to detect a fire, it is possible to turn on the lights of all the rooms and sound an alarm to notify the occurrence of the abnormality.

The procedure of setting / controlling the control restriction of the terminal device will be described with reference to the flowchart shown in FIG. S1 to S10 shown in FIG. 2 indicate the step sequence of the processing procedure.

First, in steps S1 to S4, the contents / conditions of the exceptional pattern control that can be centrally controlled from the HC 2 in a room where a person is present, and the terminal device T to be excluded from the setting that does not perform the centralized control are set. Next, in step S5, if the HC2 is instructed to perform centralized control, step S5 is performed.
At 6, it is determined whether or not the exceptional pattern control is set. Then, when the exception pattern control is set, the process proceeds to step S9, the terminal device T is controlled, the control result is displayed on the display unit of the HC 2 in step S10a, and the series of operations ends.

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 are no people in the room, the process proceeds to step S9. Then, when there is a person in the room, in step S8, it is determined whether or not the terminal device T to be controlled is set to be excluded from the devices set as the target of the centralized control.

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

Further, according to the fourth aspect of the invention, when the home controller or the like centrally controls terminal devices in other rooms,
The room controller allows the terminal device in the room to set priority control that gives priority to control in the room. This setting can also be commanded by the operation unit on the home controller side. When priority control that prioritizes control in the room is set, centralized control on the home controller side
It does not reach the terminal device in the room for which the priority control is set, and the control of the terminal device in the room is given priority.

Further, even in a room in which priority control is set, it is possible to set a terminal device that may perform centralized control and a terminal device that does not allow centralized control. Therefore, even if the home controller performs the pattern control for turning off a plurality of terminal devices all at once, the terminal devices that do not allow the centralized control of the room in which the priority control is set are excluded from the control.

Thus, contrary to the convenience of controlling everything from the home controller, the disadvantage of unilateral control is set by the present invention so that the control on the terminal device side is given priority at any time. By making it possible, the home bus system can be made more effective.
