Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a home automation system that uses commercial 100V power lines as a communication medium to remotely control devices connected to the power lines and distributed. It relates to a controller used in the system.

Prior Art A home automation system (hereinafter referred to as the system) has a configuration as shown in Fig. 3, and a controller 21 used in this system has a configuration as shown in Fig. 4. .

In Figures 3 and 4, 18 is a commercial 100V power line used as a communication medium, and 20a to 20
n is n loads remotely controlled by the controller 21, each with its own adapter 19a to 19.
It is connected to the power line 18 via n. The adapters 19a to 19n receive control signals from the controller 21 and connect to the loads 20a to 19n.
20n, and control result loads 20a to 20n.
A signal indicating the status of is sent back to the controller 21 via the power line 18. 21 is a controller, which has operation keys 7 to 10 and LEDs 11 to 10 operated by the user.
14, changeover switch 15, and depth switch 16
and notification means 17. Operation keys 7-1
The number 0 corresponds to the number of loads 20a to 20n, and each corresponds to an individual load. For example, the load 20c is turned on or off by operating the third operation key 9. It's becoming like that. LEDs 11 to 14 are also arranged in a number corresponding to the number of loads 20a to 20n, and for example, when the load 20c is turned on and a reply signal is received from the adapter 19c, the LED 13 lights up.
Each corresponds to an individual load. The changeover switch 15 is used to change the operation mode of the controller 21, and when the system is installed, the same address as the address of the adapter connected to each load is set to the operation keys 7 to 10 (hereinafter referred to as
It has a setting mode for setting an address (described as setting an address) and a normal mode for returning to normal use after setting, and can be switched manually. The deep switch 16 is connected to each operation key 7 to 1.
This is for setting an address to 0. For example, setting the first one on and the others off represents address 1, and setting the second one on and the others off represents address 2. Reference numeral 17 denotes a notification means that generates a notification sound every time the address setting by the dip switch 16 is completed by one of the n operation keys 7 to 10.

With the above configuration, the controller 21 operates as follows.

First, the changeover switch 15 is set to the setting mode, and the deep switch 16 is used to set the address. Next, when one of the operation keys 7 to 10, for example 7, is pressed, the address set by the deep switch 16 will be set as the address of the operation key 7, and the notification means 17 will notify with a notification sound that the address setting has been completed. do. Next, when a new address is set with the dip switch 16 and another operation key, for example 8, is pressed, the address is set for the operation key 8. In this way, sequentially operate keys 7~
Set address 10. Next, the changeover switch 15 is switched to the normal mode and the system is placed in a normal operating state.

In this normal use state, for example, when the user wants to turn on the load 20c by remote control, he presses the operation key 9. Then, from the controller 21 to the load 2
An on signal to 0c is sent to the adapter 19c via the power line 18, and the load 20c is turned on under the control of the adapter 19c. When the load 20c is turned on, this signal is sent from the adapter 19c to the controller 21 via the power line 18, and the LED 13 lights up, allowing the user to know that the load 20c has been turned on.

Problems to be Solved by the Invention However, with the above configuration, there is a problem in that when setting addresses, it is difficult to know how far the addresses of the operation keys have been set. In other words,
If you can connect the addresses of the n operation keys continuously, it won't be much of a problem, but if you interrupt the setting for other work during the setting of the palace,
It may become unclear which operation key has been used to set the address. In such a case, in the conventional configuration, the notification means 17 makes a notification each time the setting of one operation key is completed, but this notification is for the operation key that was operated, and it is not possible to set the address up to which operation key. It does not indicate whether or not this is being done.

The present invention solves these problems, and provides a controller that can easily determine which operation key has been set for the address of the operation key, and that can prevent address settings from being omitted. It is an object.

Means for Solving the Problems In order to achieve the above object, the present invention provides a storage means having a plurality of storage areas, an input means having a plurality of operation keys, and display contents change by operation of the input means. It is composed of a display means having a display element or a display area having a plurality of display elements, and a storage control means, an input control means, and a display control means for controlling the storage means, input means, and display means, respectively, and the plurality of storage areas. and a plurality of operation keys, respectively, and a plurality of storage areas and a plurality of display elements or display areas, and display whether or not new data has been input to each storage area. The controller is configured to display information based on changes in the number of characters.

Effect With the above configuration, the display element corresponding to the operation key whose setting operation by the input means has been completed lights up, and by checking the lighting state of the display element, the setting/setting operation can be performed.
The controller can easily determine whether or not the setting has been made.

Embodiment An embodiment of the controller of the present invention will be described below with reference to FIGS. 1 and 2. In addition, Figure 3・
The description of members having the same functions as those of the conventional example explained in FIG. 4 will be simplified. FIG. 1 is a block diagram showing a controller of the present invention, and FIG. 2 is a conceptual diagram showing its specific configuration. In the figure, reference numeral 1 denotes an input means operated by the user, which includes operation keys 7 to 10, a changeover switch 15, and a dip switch 16. Reference numeral 2 denotes an input control means that sends a signal to the storage control means 3 to control the storage means 4 so that it can store data when the changeover switch 15 is set to the setting mode. 3 is a storage control means which, when receiving a signal from the input control means 2, specifies a storage area in the storage means 4 and transmits this signal to the storage means 4, and at the same time transmits this signal to the display control means 5; It is. Reference numeral 4 denotes a storage means that has a plurality of storage areas and receives signals received from the storage control means 3.
Reference numeral 5 denotes display control means for driving the display means 6.
Reference numeral 6 denotes display means consisting of a plurality of LEDs 11 to 14, and is attached to each of the operation keys 7 to 10 constituting the input means.

The address setting operation when installing the system using the controller configured as above will be described below.

First, the changeover switch 15 constituting the input means 1 is switched to the setting mode side. When this switching is performed, the input control means 2 operates and the storage control means 3
is driven to make the storage means 4 ready for storage, and at the same time, the display control means 5 constitutes the display means 6.
Turn off all LEDs 11 to 14. Next, the address of the operation key 7 is set to "1", for example.

To make this setting, first turn on the deep switch 16 and turn off switches 2 to 8, press the operation key 7 to drive the memory control means 3, and change the memory location of the memory means 4 to the location corresponding to the operation key 7. This is done by specifying. When the designation of the storage location using the operation key 7 is completed, this signal is input from the storage control means 3 to the display control means 5, and the display control means 5 operates to turn on the LED 11. Following the same procedure, addresses can be set for operation keys 8 to 10, and each time the address setting for one operation key is completed, the address corresponding to that operation key is set.
The LEDs 12 to 14 change from the off state to the on state. Therefore, even if the operator interrupts the address setting operation, the one that is lit among LEDs 11 to 14 indicates that the address setting has been completed, and the address setting is complete. when it's finished
Since all of the LEDs 11 to 14 are lit, there is no possibility that the settings will be omitted.

After setting the addresses of all the operation keys 7 to 10 in this way, the changeover switch 15 is switched to the normal mode side to bring the system into the normal operating state, and the system becomes ready for use. By switching the setting of the changeover switch 15 to the normal mode side, this signal is input from the input control means 2 to the storage control means 3, and the storage control means 3 operates to drive the display control means 5. The display control means 5 controls all of the LEDs 11 to 14 from a lit state to an extinguished state. In this way, preparation for the normal use state is completed, and the LEDs 11 to 14 are turned on and off to indicate the on/off state of the load during normal use as described in the conventional example.

Also, if you wish to change the addresses set for operation keys 7 to 10 for some reason, switch the selector switch 15 back to the setting mode side and
This can be done by turning off the LEDs 11 to 14, operating the deep switch 16, and operating the operation keys 7 to 10 that require address setting changes. In this case as well, operation keys 7 to 10 for which the address setting change has been completed.
Since the LEDs 11 to 14 corresponding to the address are lit, erroneous address setting will not occur. Once you have finished changing the necessary address settings, turn switch 1.
Switch 3 to the normal mode side again, and all LEDs
Turn off lights 11 to 14 and use the system.

In this example, the loads that can be remotely controlled include lighting equipment such as fluorescent lights, audiovisual appliances such as televisions, video tape recorders, and stereos, heating and cooling equipment such as air conditioners and electric stoves, and fire alarms and water leak alarms. These are devices that normally use electricity as an energy source, such as security-related equipment such as.

Further, in this embodiment, the storage control means 3 only had the function of specifying the storage location of the signal for the storage means 4, but the program of the storage control means 3 has been enriched to store the signal. A function for specifying a location and the information stored in the storage means 4 are called up, this called information is compared with the signal input from the input control means 2, and only when the two match, this signal is sent to the display control means 5. The second embodiment of the present invention is configured to output the data.

With this configuration, if a failure or abnormality occurs in the storage means 4, it can be discovered at an early stage, and it is possible to prevent an accident of the entire system.

Effects of the Invention As described above, according to the present invention, it is possible to provide a controller that can prevent address setting from being omitted when installing a home automation system.
