DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to the accompanying drawings for the understanding of the present invention. It should be noted that the following embodiments are examples of embodying the present invention and do not limit the technical scope of the present invention. Figure 1
2 is a configuration diagram of an embodiment home bus system, FIG. 2 is an explanatory diagram showing a connection relationship between a home bus and a terminal device, and FIG. 3 is a flowchart showing a processing procedure of device-side control priority setting.
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, and has a home bus controller 2 (hereinafter referred to as HB) at one end thereof.
C2) is connected, the information outlet 3 is arranged at a key point, and each terminal device T1, T2, T3 is connected to the information outlet 3. The IFU 9 inserted between the terminal device T and the information outlet 3 is an interface unit for matching the terminal device T and the home bus 1. Further, the home bus 1 is connected to a security sensor 4, such as a smoke sensor, a crime prevention sensor, a gas sensor, and an environment sensor 5 such as a temperature sensor and a humidity sensor, and transmits detection information to the HBC 2. HBC2
In addition to performing on / off control of each terminal device T, etc., it performs state monitoring to control based on environmental conditions or external incoming information, and also controls based on incoming information from each terminal device. To do. Further, an alarm, a report, etc. are executed for the abnormal information from the security sensor 4. Moreover,
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 automation and monitoring control of home appliances and household equipment. For example, on / off control to turn off lighting, air conditioning, etc. in an unused room from the HBC2 by remote control, or to activate the air conditioning from a certain time before to bring it to a comfortable temperature, according to environmental conditions. This includes control for switching energy sources such as gas, electricity, and solar heat and energy-saving operation, crime prevention by smoke sensor, crime prevention sensor, leak sensor, etc., and control for disaster prevention.

In the on / off control of each terminal equipment T in this embodiment, as shown in FIG. 2, the on / off of the power supply of each terminal equipment T is controlled from the HBC 2 through the home bus 1. For example, when the terminal device T1 is a lighting device, when the terminal device T1 is turned on by the operation unit provided in the HBC2 to turn on the lighting device, the operation activates the relay 8 through the home bus 1, and the terminal device T1 is turned on. The lighting device that is T1 is turned on. On the other hand, it is turned on at the terminal device T side.
To turn off, in the case of the lighting device in the above example, by operating the operation unit 10 of the lighting device (such as a wall switch in the room where the lighting device is installed), the operation is performed from the home bus 1 to the HBC 2. It is transmitted, the relay 8 is operated from the HBC 2, and the illumination is turned on and off. Since the terminal device T can be controlled to be turned on / off from the HBC 2 as described above, for example, at bedtime, a batch light extinction is performed in which unnecessary lights are collectively extinguished by leaving gate lights, entrance lights, etc. be able to. In this case, if the target of the terminal device T (lighting device in this example) to be turned off collectively is set in advance,
The relay 8 of the terminal device T to be set is operated. However, when multiple people are using the system, when the person turns off all the lights for sleeping, as in the above example, the person who turns off all the lights even if one person is in use However, it may turn off the light without noticing it. In order to prevent such an adverse effect, the HBC 2 is provided with device-side control priority setting means for giving priority to control on the terminal device T side. When the device-side control priority is set, the terminal device T to which the device-side control priority is set is excluded from the target of the centralized control by the operation unit on the HBC2 side, and becomes an exclusion target such as collective light-off as described above. The processing procedure for setting the device-side control priority will be described with reference to the flowchart shown in FIG. S1 to S5 shown in the figure show the step sequence of the processing procedure. First, in S1, it is determined whether or not there is a device-side control priority setting. When the device side control priority is set, the process proceeds to S2, and the terminal device T to be set is designated. Here, the terminal device T designated as device-side control priority is excluded from the centralized control of the HBC 2 (S3). The terminal device T set as device-side control priority is displayed on the display unit of the HBC 2 (S4).
When the device-side control priority is canceled, if No in the determination in S1, the setting is canceled by designating the terminal device T to be canceled in S5, and H is set in S6.
This is incorporated into the centralized control of the BC2, and the device-side control priority display is deleted (S7). When setting the device-side control priority from the terminal device T, the priority setting signal is input to the HBC 2 through the home bus 1 by operating the terminal device T for the priority setting, and the processing from S1 of the above processing procedure is performed. Then, the priority setting process is performed in the same manner.

[0008]

According to the present invention, in the home bus controller, the device side control for each terminal device by the operation unit on the terminal device side is set to the device side control priority, which has priority over the centralized control by the home bus controller. be able to. This setting can be instructed from the operation unit on the home bus controller side or from the operation unit on the terminal device side. Therefore, when the device side control priority setting is made, the operation unit on the home controller side can be used for centralization. The control does not reach the terminal device for which the device side control priority is set, and the control on the terminal device side is prioritized. Therefore, even when the home controller performs batch control for turning off a plurality of terminal devices at once, the terminal device for which the device-side control priority is set is excluded from the control. In this way, contrary to the convenience of centrally controlling everything from the home bus controller, the adverse effect of unilateral control can be set according to the present invention by giving priority to control on the terminal device side at any time. By doing so, the home bus system can be made more effective.
