Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Field of Industrial Application) The present invention relates to a system control device that comprehensively controls terminal equipment in a home.

(Prior Art) Recently, a system control device has been developed in which a home bus is installed in the home and a main controller, a sub-controller for controlling terminal equipment, and an interface unit for matching terminal equipment are connected to the home bus. , is being put into practical use.

The main controller performs overall control of the system control device, and gives operational instructions to the sub-controller and interface unit.

This operation instruction is based on addresses predetermined for the subcontroller and the interface unit, respectively.

Regarding addresses, each of the subcontroller and the interface unit has an address setting switch, which is set by a maintenance worker or user.

(Problem to be Solved by the Invention) However, when the number of subcontrollers and interface units increases, the same address may be mistakenly set twice, and normal operation will no longer be possible.

This invention was made in view of the above circumstances,
The purpose is to provide a highly reliable system control device that can prevent type 2 address settings and thereby always enable proper operation.

[Configuration of the Invention (Means for Solving the Problems) A sub-controller for controlling terminal equipment, an interface unit for matching terminal equipment, setting addresses of these sub-controllers and interface units, and setting the addresses of the sub-controller and interface unit. and a main controller that gives operation instructions to the unit.

(Function) The main controller automatically sets the addresses of the subcontroller and interface unit.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In Figure 1, 1 is a home bus installed in the home,
The home bus 1 includes a main controller 10, a subcontroller 20. Interface unit (IFU) 40
Connect.

The main controller 10 performs overall control of the system control device, and is a CPU II.

Input/output interface 12. ROM (read only)
Memory) 13, RAM (Random Access Memory) 14. Operator 150 Display 16. and a battery power source 17, and gives operation instructions to the sub-controller 20 and the interface unit 40.

The ROM 13 is for storing operating programs.

The RAM 14 stores an address table, which will be described later, and also stores the sub-controller 20 and interface unit 40.
It is used for registering settings for Atonenos.

The battery power supply 17 is for backup in case of power outage.

On the other hand, the sub-controller 10 is for controlling terminal equipment, and the CPU 21 . Input/output interface 22, ROM23
, RAM24. Confirmation switch 25, display 26. and a battery power supply 27, and the main controller 10
Terminal equipment such as bath equipment 30 according to operation instructions from
control.

The ROM 23 is for storing operating programs.

The RAM 24 is used for address registration and the like.

The battery 1g27 is for backup in case of power outage.

The interface unit 40 is for terminal equipment matching, and is for the CPU 41 . Input/output interface 42, ROM4B
, RAM44. Confirmation switch 45, display 46. and a battery power source 47, and provides operation instructions from the main controller 10 to a terminal device such as an air conditioner 50.

ROM4B is for storing operating programs.

The RAM 44 is used for address registration and the like.

The battery power source 47 is for backup in case of power outage.

Next, the operation of the above configuration will be explained with reference to FIGS. 2 to 5.

2 shows the address registration operation of the sub-controller 30 and the interface unit 40, FIG. 3 shows the address registration operation of the main controller 10, FIG. 4 shows the address table in the main controller 1o, and FIG. 5 shows the sub-controller 30 and the interface unit 40. This shows the address registration operation.

Home bus 1. Main controller 10. Sub controller 20. When the worker turns on the power to the main controller 10 and the sub-controller 20 after the installation of the interface unit 40 is completed, the main controller 10 and the sub-controller 2o become operational.

When the power is turned on, the subcontroller 2o is registered! The request signal and self-device data are transmitted to the main controller 10.

When the main controller 10 receives the registration request signal,
Determine what kind of device it is from the self-device data attached to the registration request signal, and if it is a subcontroller, check the vacant part of the controller side address in the previous stage of the address table (Fig. Select the bit code corresponding to
is stored and registered in the RAM 14 as address data.

Furthermore, the registered address data is sent to the home bus 1.

The sub-controller 20 receives the address data returned from the main controller 10, and stores and registers it in the RAM 24 as its own.

If there are several sub-controllers 20, address data is sequentially selected and registered in the direction of the solid line arrow in the address table.

When a worker turns on the power to the interface unit 40, the interface unit 40 becomes operational.

When the power is turned on, the interface unit 40 transmits a registration request signal and self-device data to the main controller 10.

When the main controller 10 receives the registration request signal,
Determine what kind of device it is from the self-device data attached to the registration request signal, and if it is an interface unit, select the bit code that corresponds to the empty part of the interface unit side address in the latter stage of the address table in RAM 14. and connect it to the interface unit 40
is stored and registered in the RAM 14 as address data.

Furthermore, the registered address data is sent to the home bus 1.

The interface unit 40 is the main controller 1
It receives the address data as a reply from 0 and stores and registers it in the RAM 44 as its own.

When there are several interface units 40, address data is sequentially selected and registered in the direction of the dashed arrow in the address table.

In this way, the main controller 10 automatically sets the addresses of the sub-controller 20 and the interface unit 40, thereby eliminating the need for an address setting operation by an operator or user, which is convenient.

In particular, even if there are a large number of subcontrollers 20 and interface units 40, there is no problem such as double address setting, and proper operation can always be performed.

Furthermore, there is no need to provide an address setting switch on the sub-controller 20 and the interface unit 40, and the number of input ports of the CPU can accordingly be reduced.
The configuration is simple and costs can be reduced.

On the other hand, the confirmation switch 25 in the sub-controller 20
When turned on, the sub-controller 20 displays its own registered address data on the display 26 for a predetermined period of time, for example, one minute. Therefore, the worker or user can easily check whether the address data is reliably registered or what kind of address data has been registered, resulting in excellent reliability.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without changing the gist.

[Effects of the Invention] As described above, according to the present invention, a sub-controller for terminal device control, an interface unit for terminal device matching, and addresses of these sub-controllers and interface units are set, and the sub-controller and a main controller that gives operation instructions to the interface unit, it is possible to prevent duplicate address settings, thereby providing a highly reliable system control device that always enables proper operation. can.
