Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a human output interface for a microcomputer to which a remote controller having a plurality of operation switches is connected.

<Conventional technology> Generally, for example, in a water heater, a remote controller (hereinafter referred to as a remote control) is provided with operation switches assigned to each function such as an operation switch, a temperature control switch, a reservation switch, etc. The coater (hereinafter referred to as a microcomputer) is connected via an input/output interface, and various control processes are performed in accordance with the operations of the above-mentioned operation switches.

In such devices, some of the operation switches of the remote control may be omitted or the arrangement of the operation switches may be slightly changed depending on the model. For example, as shown in Fig. 3, in a remote control of a certain model A (Fig. If we assume that the remote control is arranged according to function up to °, then in the remote control of another model B (see figure (b)), the operation switches indicated by the symbol Pao and "force ° ° are omitted, and the operation switches indicated by the symbol Pao" are omitted, and the operation switches indicated by The position of the operation switch has been changed to the "O°" position.Furthermore, in the remote control of another model C ((C) in the same figure), the operation switch with the symbol "cover" is omitted compared to model A. And “I゛°
~ “The arrangement of the operation switches up to Opa is shifted one by one.

By the way, conventionally, the output of each operation switch of a remote control is made to correspond to each terminal of an input port of a microcomputer in an I-to-I relationship. Therefore, now, as shown in Figure 4,
If the outputs of the operation switches "A" to "Force" of model A are made to correspond to the function-specific terminals a to f of the input port of the microcomputer, if the operation switch with the symbol "A" is operated, the a terminal will be output. When the operation switch "A" is operated, signals are input to the b terminals, so the microcontroller outputs "A""~"
Performs processing corresponding to each operation switch of power.

However, the key layouts of the remote controllers for models B and C are partially different, so if these remote controllers are connected to a microcontroller with the key layouts unchanged, the functions assigned to the operation switches will be processed differently. Become. For example, for model B, even if you operate the operation switch assigned the function "Engine", the output signal will be input to the terminal indicated by the symbol e on the microcomputer, so the operation switch for the function "O" of model A The same process will be performed.

In order to avoid such inconveniences, the conventional methods were to (1) change the signal wiring of the remote control's operation switch for each model;
Alternatively, (II) the processing program of the microcomputer that recognizes the signal from the operation switch is changed for each model.

<Problem to be solved by the invention> However, in the case of item (i), although it is not necessary to change the processing program of the microcomputer, it is necessary to prepare individual monoyls with different wiring depending on the remote control model. This is disadvantageous in terms of cost. Also, (ii)
In this case, although the remote control modules can be standardized, changing the microcomputer processing program each time depending on the remote control model is extremely complicated and requires a great deal of effort.

The present invention has been made in view of the above circumstances, and even when the arrangement of the remote control operation switches is slightly changed depending on the model, there is no need to change the remote control operation switch module, and, The purpose is to enable various control processes to be performed according to operation switches without changing the main processing program of a microcomputer.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides the following in an input/output interface of a microcomputer to which a remote controller having a plurality of operation switches assigned according to functions is connected. Adopt the composition.

-4~ That is, in the present invention, a model designation switch section that outputs a model designation signal according to each model, a processing procedure memory that stores different switch arrangement conversion processing procedures depending on each model, and a model designation switch section that outputs a model designation signal according to each model, a data selection section that reads out a switch arrangement conversion processing procedure stored in the processing procedure memory based on the model designation signal from the switch section; and a switch arrangement conversion processing section that converts the arrangement of each operation switch of the controller into a standardized terminal arrangement for each function of the microcomputer.

<Operation> In the above configuration, when connecting the remote control to the microcomputer, the model designation switch section is operated according to the model. Then, a model designation signal is output from the model designation switch section, and this signal is given to the data selection section. The data selection section reads out the switch arrangement conversion processing procedure stored in the processing procedure memory based on this model designation signal, and sends the data of this switch arrangement conversion processing procedure to the switch arrangement conversion processing section. The switch arrangement conversion processing section converts human input signals from each operation switch of the remote control into a standardized function-specific terminal arrangement of the microcomputer based on this switch arrangement conversion processing procedure.

Therefore, even if the physical operation switch arrangement of the remote control differs depending on the model, the microcontroller itself will receive signals from the operation switches according to the terminal arrangement for each function, and will respond according to the operation switch of the remote control. This will ensure that the specified processing is executed reliably.

<Embodiment> FIG. 1 is a block diagram including a human output interface of a micro combi coater according to an embodiment of the present invention. In the figure, reference numeral 1 is a remote controller, and 2 is a switch operating section provided on the remote controller 2. This switch operating section 2 is provided with operating switches assigned to each function.

Reference numeral 4 denotes a microcomputer, which is composed of a human horn interface 6 and a microcomputer main body part 8. Then, the microcomputer main unit 8
has input terminals a to f arranged according to standardized functions. IO is a model designation switch section that is selectively operated according to each model. For example, when the remote control 1 having the arrangement of operation switches shown in FIG. 3(a) is connected to the microcomputer 4, both switches 10a , 10b are both turned on,
As a result, the model designation switch section 10 outputs a model designation signal of "OO". Furthermore, when connecting a remote control having the arrangement of operation switches shown in FIG. 3(b), only one switch 10a is turned on, thereby causing the
The model designation signal “l” is output. Also, as shown in Fig. 3 (C)
When connecting a remote controller having the arrangement of operation switches shown in FIG. 1, only the other switch IOb is turned on, thereby outputting a model designation signal of "10". In addition,
In this example, the arrangement of the operation switches on the remote control 1 can only be selected when there are four or less types, but by increasing the number of switches in the model specification switch section, it is possible to accommodate changes in the arrangement of the operation switches in many different types. I can do it.

Reference numeral 12 denotes a processing procedure memory in which switch arrangement conversion processing procedures that differ for each model are stored.

Further, 14 is a data selection unit that reads out the switch arrangement conversion processing procedure stored in the processing procedure memory 12 based on the model specification signal given from the model specification switch unit 10, and 16 is the switch arrangement conversion selected by the data selection unit. This is a switch arrangement conversion processing unit that converts the arrangement of each operation switch of the remote control 1 into a standardized arrangement of input terminals a to f for each function of the microcomputer 4 based on a processing procedure.

Next, the switch arrangement conversion processing operation of the input/output interface in the above configuration will be explained with reference to the flowchart shown in FIG. In this case, the functions assigned to the operation switch inputs ``input'' to ``force'' of model A shown in FIG. shall be allowed to do so.

When connecting the remote controller 1 to the input/output interface 6 of the microcomputer 4, the model designation switch section 10 is operated to generate a model designation signal corresponding to the model. For example, since model B is connected to a remote controller having the operation switch arrangement shown in FIG. 3(b), in this case, one switch 10a of the model designating switch section IO is turned on.

As a result, a model designation signal of "01" is output from the model designation switch section 10, and this model designation signal is given to the data selection section 14. The data selection unit 14 reads out the switch arrangement conversion process procedure corresponding to model B stored in the process procedure memory 12 based on the model designation signal (“01” in this example) given from the model designation switch unit 10. , and sends the data of this switch arrangement conversion processing procedure to the switch arrangement conversion processing section 16.

On the other hand, the microcomputer main body section 8 provides the switch arrangement conversion processing section 16 with a sampling signal that samples the output signal from the switch operation section 2 of the remote control at a constant period. If there is a switch input during this sampling period (step 2), this manual data is taken into the switch arrangement conversion processing section 16 (step 2).

The switch arrangement conversion processing section I6 converts the human input signal from the switch operation section 2 of the remote controller 1 into the standardized function-specific terminals of the microcomputer 4 based on the switch arrangement conversion processing procedure given from the processing procedure memory 12 (step ■). Convert to an array (step ■). That is, compared to the remote control of model A, the remote control of model B has the same arrangement from numbers A to A, but the position of the operation switch for "work" has been changed to the position of "o", and The operation switch shown by the cover is omitted. Therefore, a process is performed in which the "manpower" of the switch is shifted by one bit toward the higher order side, and the lower two bits are rewritten to invalid data. As a result, when each of the operating switches "A" to "Engine" is operated, signals corresponding to these operating switches are input to terminals a to d of the microcomputer main body section 8. Therefore, the process corresponding to the operation switch of the remote controller 1 is reliably executed (step 2). Then, the microcomputer main unit 8
After clearing the input request (step ■), performs other processing until the next sampling period (step ■).

Further, for example, in model C, the remote control 1 having the arrangement of operation switches shown in FIG.
'Turn on Ob. As a result, the model specification switch section I
Since a model designation signal of '10' is output from O, the data selection unit 14 reads the switch arrangement conversion processing procedure corresponding to model C stored in the processing procedure memory 12 based on this model designation signal, The data of this switch arrangement conversion processing procedure is sent to the switch arrangement conversion processing section 16.Compared with model A, in this model C remote control, the operation switches with the code ``A'' are in the same arrangement, and the operation switches with the code ``°°
The operation switches for "I" to "O" are omitted, and the arrangement of the operation switches from "I" to "OPA" is shifted by one. Therefore, the switch inputs from "I" to "O" are changed by "2". At the same time as shifting by one bit towards the position side,
Processing is performed to rewrite the lower 1 bit to invalid data.

As a result, when each of the operation switches "A" to "O" is operated, a signal corresponding to the operation switch is input to the terminals a to d of the microcomputer main body section 8. Therefore, the process corresponding to the operation switch of the remote control 1 is reliably executed.

<Effects of the Invention> According to the present invention, the difference between the physical operation switch arrangement and the function-specific terminal arrangement of the microcomputer main body is eliminated by interposing a simple input/output interface. Even if you slightly change the arrangement of the operation switches on the remote control, there is no need to change the module for the operation switches on the remote control, and the main processing program of the microcontroller can be adjusted according to the operation switches provided on each model. Various control processes can now be performed. As a result, excellent effects such as the ability to use common remote control modules and cost reductions are achieved.
