Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a shared control device. Specifically, the present invention, according to the embedded model and the model used,
The present invention relates to a shared control device that allows setting of a model of an operation unit side controller and a main body side controller.

[Background Art] For example, in an automatic bathtub, an operation unit side controller incorporated in an operation panel provided in a bathroom and a main body side controller incorporated in a main body heat source device are connected by a signal line. . Further, also in the case of a gas stove or the like, the operation unit side controller provided on the front operation panel and the internal main body side controller are connected by a signal line. These control devices are generally shared so that they can be used for different models, so when incorporating them into the equipment, the controller on the operation unit side and the controller on the main body side should be matched according to the function of the model. It is necessary to set the model of.

FIG. 5 shows a configuration of a conventional shared control device, in which the operation unit side controller 31 includes an operation unit side CPU3.
3 is built in, and the main body side controller 32 has a main body side C
Built-in PU34. Transmitting port P ₃ of the operation unit side CPU33
A serial transmission line 35 connects between the main body side CPU 34 and the reception port P ₂ of the main body side CPU 34. Further, in the controller 31 on the operation unit side, a pull-up resistor R ₂ and a model switch 36 such as a DIP switch or jumper wire are inserted in series between the power supply line and the ground, and the midpoint of these is connected to the CPU 33 of the operation unit side. Connected to model selection port P ₄ . Therefore, by switching the model selector 36 on or off and setting the input level to the model selection port P ₄ to L or H, it is possible to switch to either of two models. Similarly, in the controller 32 on the main unit side, connect the middle point of the model changeover device 37 such as DIP switch or jumper wire and the pull-up resistor R ₁ to the model selection port P ₁ of the CPU 34 on the main body side to turn on the model changeover device 37 or By switching it off, it can be set to either of two types.

Therefore, both the operation unit side controller 31 and the main body side controller 32 read the levels of the respective model selection ports P ₄ and P ₁ and independently set the models according to the procedure shown in the flowchart of FIG. That is, when the device is turned on (S41), the initialization routine is executed (S41).
42) After that, read the input level of the model selection port P (S4
3), determine the level of model selection port P ₄ or P ₁ (S4
Four). If the level is L, for example, it is determined as model A (S
45) A flag indicating model A is set in the model determination flag, and if the level is H, it is determined to be model B, for example (S46), and a flag indicating model B is set in the model determination flag.

In the conventional example, the serial transmission line 35 was used only for transmitting changes in the states of the operation switches and buttons on the operation panel to the main body controller.

[Problems to be Solved by the Invention] In the conventional shared control device, as described above, the operation unit side controller and the main body side controller are individually provided with the model changer, and perform the model setting work independently. .

For this reason, when incorporating this shared control device into a device, it is necessary to switch the model selector such as a DIP switch on both the controller on the operation unit side and the controller on the main unit to set the device. It took a lot of time. In addition, there is a problem that the DIP switch is apt to be mistakenly switched and the device does not operate properly unless the setting model of the operation unit side controller and that of the main body side controller match.

The present invention has been made in view of the above-mentioned drawbacks of conventional examples, and an object of the present invention is to facilitate the model setting work and to make the model setting mismatch between the operation unit side controller and the main body side controller. To prevent.

[Means for Solving the Problems] A shared control device of the present invention includes an operation unit side controller including a model switching device, and a main body side controller connected to the operation unit side controller by a signal transmitting unit, When sending data from the controller on the operation unit side to the controller on the main unit side, the model code for distinguishing the model set by the model change is included in the sent data, and the model setting for the main unit controller is performed. It is characterized by being configured to.

[Operation] In the present invention, the model changer is provided only in the operation unit side controller, and the model setting in the main body side controller includes the model code in the transmission data from the operation unit side controller to the main body side controller. It is done by doing.

Therefore, the model setting work only needs to be performed for the operation unit side controller, and the model setting work when the shared controller device is incorporated in the device can be easily performed. Moreover, since the model setting of the main body controller is performed automatically, there is no discrepancy in the setting model between the operating unit side controller and the main body side controller as in the conventional example, and the reliability of the shared control device is improved. Can be improved.
