Abstract

PURPOSE:To easily discriminate proper combination by devising the device such that one device generates an identification signal to apply a display of inadequate combination if the combination between one device and other device is not proper. CONSTITUTION:Upon the receipt of data including an identification signal from a bath use remote controller 4, a main body 3 uses a discrimination means 24 so as to discriminate whether or not the sent identification signal is suitable for the main body 3. Moreover, the main body 3, when the data including an identification is sent from a main remote controller 5, uses the discrimination means 24 so as to discriminate whether or not the sent identification signal is suited to the main body 3. If the main body 3 and the bath use remote controller 4 are not matched with each other, an error signal generating means 25 sends a device type error signal to the bath use remote controller 4 and the main remote controller 6 based on the result of discrimination of the discrimination means 24. Furthermore, when the device type error code is blinked on display means 26, 27, the operation by the bath use remote controller 4 and the main remote controller 5 is disabled. Then it is reset by taking out the power cord.

Therefore, there may be an inconvenience that the model of the main body and the model of the remote control do not match at the time of installation.

If a remote control of a different model is connected to the main body of a certain model, the main body may not be able to be operated by the remote control, the main body may malfunction, or the main body may not operate.

Therefore, when installing the remote control, the installer needs to determine whether or not the main body and the remote control are compatible. However, it has been difficult to require the worker who installs the device to check the product number etc. for each device to be installed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a transmitting device that can easily determine whether or not one transmitting device is compatible with the other receiving device. The purpose is to provide an identification device.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a transmitting device that transmits data from at least one device 101 to another device 102, as shown in FIG. 101 includes identification signal generating means 103 for generating an identification signal to the other device 102;
The determination means 104 determines whether the identification signal transmitted from the one device 101 is compatible, and the determination means 1
and an error signal generating means 105 which generates a signal indicating non-conformity when 04 is determined to be non-conforming, and display means which displays the non-conformity upon receiving a signal indicating non-conformity from the error signal generating means 105. The technical means is to have 10G.

Note that the display means 106 may be provided integrally with the other device 102 or may be provided separately from the other device 102. In addition, in the case where one device 101 and the other device 102 perform transmission and reception, the display means 106 is displayed on one device 101.
It may be provided integrally with the

[Operation] Connects one device to the other device. Next, one device transmits an identification signal to the other device.

When the other device receives an identification signal from one device, the determining means determines whether the identification signal is a signal of one device that is compatible with the other device.

If the determination result of the determining means is at least non-conformity, the error signal generating means outputs a signal indicating non-conformity to the display means. When the display means receives a signal indicating nonconformity from the error signal generation means, the display means uses a display means such as a visual means using a liquid crystal, a light emitting diode, a lamp, etc., or an audible means using a speaker, a buzzer, a chime, etc. ,
Non-conformance will be indicated to the user and installer.

[Effects of the Invention] According to the present invention, if the combination of one device and the other device is not appropriate, when one device generates an identification signal, the display means displays an indication of non-compatibility. Therefore, when installing equipment, operators and users can check the compatibility of one equipment with another without having to perform troublesome work such as confirming product numbers.
Nonconformity can be easily determined.

Note that the 24-bit signal transmitted at one time consists of an address, an operation code, an operand, and a parity. When transmitting a 24-bit signal, as shown in Fig. 3, a start signal of 800μ5eclli is generated at the beginning of the signal, and after that, every time 1 bit is transmitted, a start signal of 200μ5eclli is generated.

In addition, each communication section 7.16.21 has a length of 100 m5 if another device starts transmitting data after the main unit 3, bath remote control 4, or main remote control 5 has finished transmitting data.
It is set to allow ec waiting time.

Next, the identification device of the present invention will be explained.

The communication unit 16 of the bath remote control 4 includes an identification signal generating means 22 that outputs, for example, a 6-bit identification signal set according to the model of the bath remote control 4 to the main body 3 when power supply is started from the main body 3.

When the bath remote control 4 receives power from the main body 3, it sends 24-bit data including an identification signal to the main body 3 16 times in succession after 1111113 (IC).

When the main body 3 receives data including an identification signal from the bath remote control 4, the determining means 24 determines whether the sent identification signal is compatible with the main body 3. 0 In this embodiment, the main body 3 and the bath remote control 4
are compatible, so proceed to the next step.

When 112 msec has passed after data transmission from the bath remote control 4 to the main unit 3 is completed, the main remote control 5
sends 24-bit data including an identification signal to the main body 3 16 times in succession.

When the main unit 3 receives data including an identification signal from the main remote controller 5, the determining means 24 determines whether or not the sent identification signal is compatible with the main unit 3. In this embodiment, the main body 3 and the bath remote control 4 are
