Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home bus system used in home automation and the like.

0002

[Prior Art] Conventionally, this type of home bus system
Each device connected to the main unit via a bus line is equipped with a presence/absence setting switch, and by pressing this setting switch, the presence/absence mode of the pressed device can be switched. The device is configured so that the presence/absence mode of the entire system can be switched by a dedicated switch provided on the device.

FIG. 4 shows the configuration of a conventional home bus system. In FIG. 4, 1 is the main device, 2 is a bus line, 3 and 4 are multiple devices connected to bus line 2 and have different system mode operating conditions such as at home, away from home, at night, etc., and 5 and 6 are each device. A presence/absence setting switch is provided at 3 and 4 to individually switch the mode of the device itself, and 7 is a dedicated switch to switch the mode of the entire system.

Next, the operation of the above conventional example will be explained. In FIG. 4, the mode of the device 3 can be switched by pressing the presence/absence setting switch 5. Furthermore, by pressing the dedicated switch 7, the mode of the entire system including the main device 1, other devices 3, etc. in addition to the device 4 can be switched.

[0005] As described above, even in the above conventional home bus system, if presence/absence setting switches are provided for each device and the entire system, the system mode can be arbitrarily set.

[0006]

[Problems to be Solved by the Invention] However, in the conventional home bus system described above, it is not possible to switch the presence/absence mode of a single device and the presence/absence mode of the entire system with a single switch. The problem was that it was confusing because it was done with one switch. Also,
Switching the mode of the entire system at once requires pressing a dedicated switch provided on a specific device, or pressing all specific switches on each individual device, which is cumbersome.

The present invention solves these conventional problems and provides a home bus system in which the presence/absence mode of a single device or the entire system can be switched using a single switch provided on the device itself. The purpose is to provide a system.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention connects a switch for setting the presence/absence mode of its own device to a counter section for detecting the time when the switch is pressed. The alarm output is changed depending on the time the switch is pressed, and the presence/absence mode of a single device or the entire system can be selectively switched.

[0009]

[Operation] Therefore, according to the present invention, the presence/absence mode of a single device or the entire system can be switched by detecting the pressing time of the presence/absence setting switch, so there is no need to provide a dedicated switch. The presence/absence mode of the entire system can be changed using the switch. Therefore, it is possible to solve the confusion of having two setting switches, and by providing such a counter section in all devices,
This has the effect of solving the conventional trouble of pressing the setting switch of each device to switch the presence/absence mode. Furthermore, since the alarm output can be changed depending on the pressing time of the presence/absence setting switch, it is possible to prevent erroneous recognition of mode switching.

Embodiment FIG. 2 shows the system configuration of a home bus system in an embodiment of the present invention. In Figure 2,
11 is a main device that controls the entire system; 12 is an answering machine for recording messages when you are not home; 13 is a teleconverter unit for controlling the system by telephone from outside; and 14 is a device that regularly sends home information even when you are not home. An automatic notification device capable of making an emergency call, 15 an image recording unit capable of recording an image of a visitor when the guest is absent, and 16 another device having different system mode operating conditions such as at home, absent, at night, etc. Each of these devices 12 to 16 is connected to the main device 11 by a bus line 17.

FIG. 1 shows the main parts of each of these devices 12 to 16 according to the present invention. In Figure 1, 18 is C
PU, 19 is a communication circuit section, 20 is an alarm output section, 21
22 is a counter section, and 22 is a presence/absence setting switch section.

Next, the operation of the above embodiment will be explained. In the above embodiment, when the presence/absence setting switch section 22 is pressed, the counter section 21 starts monitoring the pressing time. The detection and determination of the press time is as shown in FIG.
If the pressing time t is less than or equal to t1, it is detected that the device is switching to the single mode, and the alarm output section 20 outputs an alarm with a "beep" sound, and a command to switch the presence/absence mode of the single device is sent to the CPU 18. When the press time t exceeds t1, it is detected that the system mode has been switched, a beeping sound is output from the alarm output unit 20, and the CPU 18 switches the presence/absence mode of the own device and all other devices. Commands are sent. Upon receiving this, the CPU 18 sends a control signal to the communication circuit section 19 to switch the presence/absence mode of the own device and to switch the presence/absence mode of all other devices connected to the bus line 17. send commands to. When a control signal is sent from the communication circuit section 19, all other devices receive this control signal with their own communication circuit section 19,
The data is sent to the CPU 18 of the own device, and
Switch to Away mode.

As described above, according to the above embodiment, each of the devices 12 to 16 connected to the bus line 17 is provided with the counter section 21 for detecting the pressing time of the presence/absence setting switch section 22. Since the presence/absence mode of a single device or the entire system can be selectively switched depending on the pressing time of the presence/absence setting switch section 22, the presence/absence mode of a single device or the entire system can be switched simply by pressing the setting switch of a certain device, without providing a dedicated switch. You can switch between presence/absence mode. Further, since the alarm output is changed depending on the pressing time of the presence/absence setting switch section 22, it is possible to prevent erroneous recognition of mode switching.

[0014] In the above embodiment, each device 12 to
Although the present invention has been applied to all 16 devices, the present invention can be applied to only one or more specific devices. Further, as the alarm output, in addition to the above-mentioned alarm sound, a voice display, a text display, etc. can be used.

[0015]

Effects of the Invention As is clear from the embodiments described above, the present invention provides a counter unit that detects the time when a presence/absence setting switch is pressed in a device connected to a bus line, and outputs an alarm depending on the time when the switch is pressed. In addition to changing the presence/absence mode of a single device or the entire system, it is possible to switch the presence/absence mode of a single device or the entire system with a single switch without the need for a dedicated switch. .

Further, according to the present invention, by providing such a counter section in all devices connected to the bus line, the presence/absence of all devices in the entire system can be checked by simply pressing the setting switch of a certain device. You can switch to absentee mode.

[0017] Therefore, it is possible to solve the conventional problem of pressing the setting switch of each device to switch the presence/absence mode, or the confusion of having two setting switches.

Furthermore, since the alarm output can be changed depending on the pressing time of the presence/absence setting switch,
This has the effect of preventing erroneous recognition of mode switching.
