DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a home bus system applied to home information equipment, etc., and particularly to a home bus system for information transmission and power supply such as housekeeping systems and home telephone systems, and for controlled devices. The present invention relates to a home bus system that is provided between devices and supplies control power for a controller for controlled devices together with command signals from the controller of the system.

Conventional technology In recent years, in connection with the development of home telephone systems, security systems have been developed that use these home information device communication networks as a basic system and also incorporate security devices such as automatic light-off devices and gas leak prevention devices into the system. has been done. Additionally, systems have been developed that collectively control audio and visual equipment such as television systems and audio systems. In these systems, a home bus is connected between peripheral devices such as various household information devices and security devices, and comprehensive control devices such as security controllers and telecontrollers that can control these devices all at once. Ori,
This home bus is used for transmitting control signals and transmitting and receiving power for driving the various peripheral devices mentioned above. The above-mentioned various peripheral devices connected to this home bus are provided with an inter 7/8 unit for the home bus, and a home bus system that opens and closes power lines for driving the devices based on control signals from the above-mentioned general control device. is provided.

Conventionally, in the above-mentioned home bus system, the switch has its own power supply circuit or a power supply circuit such as a dedicated power supply, and various devices are operated by driving power supplied from these power supply circuits. Further, the conventional home bus system is opened and closed by power from a power supply circuit such as the dedicated power supply in response to a control signal from the control device, thereby controlling the drive of controlled devices.

An example of such a conventional home bus system is shown in FIG. In the figure, the home bus system includes a home bus 1, a controller 2 connected to the home bus 1, and a plurality of controlled devices 3 controlled by the controller 2 via the home bus 1.
and a device power line switch 4 provided exclusively for each of the controlled devices 3..., and a central processing unit (CPU) and a latch relay in each circuit of the switch 4... The power supply circuit 5 provided together with the power supply circuit 5, etc. is configured in a variety of ways. Note that the configuration in which the power supply circuit 5 is provided in the switch 4 is just an example, and the point is that the power supply circuit 5 is provided in the switch 4.
A conventional power line switch is provided with a power supply circuit 5 that individually supplies power for CPU control commands to the power line switch.

Problems to be Solved by the Invention However, according to the above-mentioned conventional home bus system, the CPU of each of the various controlled devices, that is, the CPU of each switch.
For each of these, a dedicated power supply circuit 5 is required as an individual power supply circuit, and incorporating this dedicated power supply increases the size of the power line switch etc., which in turn increases the size of the entire home bus system. There was a problem in that it became difficult to apply it as an information device due to space constraints.

This invention was made in order to solve the above-mentioned problems of the conventional home bus system, and a power supply circuit for the control device of each controlled device is provided inside the switch, and the power supply circuit is connected to the controller via the home bus. The object of the present invention is to provide a home bus system that can be downsized by supplying electric power for driving a switch.

Means for Solving the Problems In order to achieve the above object, the home bus system according to the present invention has a switch that accepts a control command signal and electric power from a control bus, and controls a switching means to supply power to a controlled device. It was designed to be supplied to

Function: By configuring the invention as described above, there is no need to provide a power supply circuit for each controlled device connected to the control bus, and the controlled devices can be made smaller and more compact.

Furthermore, by providing a delay means that delays the switching means by a certain period of time when operation commands are issued to multiple controlled devices at the same time, it is possible to prevent operation commands from being issued to multiple controlled devices at the same time. However, it becomes possible to operate the controlled device with a time lag of a certain period of time, and therefore there is no shortage of power supplied to the control bus.

Embodiments Hereinafter, preferred embodiments of the home bus system according to the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 1 to 3 are a functional block diagram, a schematic block diagram, and a characteristic diagram showing an embodiment of the present invention. Constituent parts given the same reference numerals as in FIG. 4 indicate the same or corresponding parts. There is. In FIG. 2 showing the overall concept of the home bus system in this embodiment, reference numeral 11 denotes a home bus as a control bus and a power supply bus for driving control devices such as a CPU. A controller 12 is connected thereto. The controlled devices 3 controlled by this controller 12 are provided with switches 20 corresponding to the number of devices 3.
It is connected to the home bus 11 via...

The detailed configuration of the home bus system having the overall configuration as described above will be explained using FIG. In FIG. 1, the home bus 11 is configured to serve both as a signal bus for control signals and as a power line for supplying power. The switch 20 includes a signal transmitting/receiving section 21 as a control signal receiving means that receives control signals from the controller 12 via the signal bus 11, and a power receiving section 21 that receives power from the home bus 11 as the power line. It basically consists of a power receiving circuit 22 as a means, and a latch relay 23 as a switching means for turning on and off power supplied from an AC power source and supplying it to the controlled equipment 3 .

Further, the switch 20 in this embodiment includes a central processing unit (CPU) 24 connected to each of the signal receiving section 21 and the latch relay 23, and a controller 12 that provides operation commands to a plurality of controlled devices 3. The address switch 25 serves as an operation delay means for closing the latch relay 23 in a time-division manner when the latching relays 23 and 23 are simultaneously activated. The controlled device 3 is connected to the contact 23a side of the latch relay 23, and the AC power source for driving the device is connected to the contact 23b side.

The configuration of the controller 12 includes each controlled device 3...
a control circuit 13 that controls the supply of control signals and drive power to each CPU 24, a power supply circuit 14 that supplies the power to the control circuit 13 and the switch 20, and an AC power supply line 15; For example, a control signal line 16 consisting of a telephone line etc. and supplying a command signal to the control circuit 13;
Keyboard 1 that similarly inputs command signals to control circuit 13
7.

Next, the operation based on the above configuration will be explained.

In the above embodiment, the controller 12 is the switch 20
A control signal using a simultaneous control command is sent to.

This control command is received by the signal transmitting/receiving section 21, analyzed by the CPU 24, and based on the value of the address switch 24, a unique delay time jls j2 or t3 is set as shown in FIG. 3(b) to (d). After elapsed, the CPU 24 outputs a control signal to the latch relay 23 to operate the latch relay 23.

In addition, power is supplied from the home bus 11, and the power receiving circuit 2
It is supplied to each part through 2.

FIG. 3 is a timing chart showing the operating timing of the home bus system of the above embodiment.

As described above, according to the above embodiment, since power is directly supplied from the home bus 11 by the power receiving circuit 22, there is an advantage that a dedicated power source is not required and the device can be miniaturized. Still, according to the above embodiment, after receiving a control command, the device operates with a delay time based on the value of the address switch 25 unique to the device, so it is possible to avoid running out of power supply capacity of the bus due to multiple devices operating at the same time. This also has the effect that a plurality of controlled devices that operate with the same command can be connected on the home bus.

Effects of the Invention As is clear from the above-mentioned embodiments, the present invention provides a switch including a power receiving means for directly receiving power supplied from the control bus and a control signal receiving means for receiving control commands from the control bus.
Since the supply of power supplied to the controlled equipment side is switched and controlled by these receiving means, circuit configurations such as a unique power supply circuit can be omitted, and the entire home bus system can also be downsized.

Furthermore, the power supply capacity of the control bus may be significantly insufficient due to power supply commands being issued to each controlled device at the same time. In order to prevent multiple controlled devices from operating simultaneously, we provide an operation delay function that operates after receiving a control command from the controller and after its own delay time has elapsed. Controlled devices can be connected.
