DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the configuration of terminal equipment in the field of home automation.

BACKGROUND TECHNOLOGY Conventionally, in this type of wireless device, as shown in FIGS.
and a child device registration code 3 stored in advance in the control means 2 to distinguish between a plurality of child devices.
, a registration code switch 24 whose settings can be changed to distinguish wireless devices from neighboring houses in an apartment complex as shown in FIG. a modulation circuit 6 that modulates the data of and an oscillation circuit 7
, an MIx circuit 8 that mixes the output of the modulation circuit 6 and the output of the oscillation circuit 7, an amplifier circuit 9 that amplifies the output of the MIx circuit 8, and an antenna 10, and radio waves are radiated into the air.

The main unit 12 includes a bandpass filter 14 that catches radio waves with an antenna 13 and passes a desired frequency band, an amplifier circuit 15 that amplifies the passed signal, a local oscillation circuit 16, and the amplifier circuit 1.
5 and the output of the local oscillation circuit 16 to output a signal in a low frequency band;
A detection circuit 18 detects the transmission data from the slave device 1 from the signal in the MIx circuit 18, an output signal of the detection circuit 18 (reproducing the registration code of the slave device 1), and a detection circuit 18 that detects the transmission data from the slave device 1 from the signal in the MIx circuit 18.
The control means 19 includes a control means 19 that determines a match with a registration code switch 21 which is located in the switch 2 and whose settings can be changed, and an alarm 23 that displays an alarm when there is a match. Therefore, in order to transmit and receive wireless signals between the slave device 1 and the master device 12, the same registration code switch 24 has been used. Also, only one frequency band was used for transmission and reception between the parent device and the slave device.

Problems to be Solved by the Invention However, with the above-described configuration, the data of the registration code switch 24 must be the same, and in an apartment complex, if the same code is used in neighboring houses, However, they all had the problem of activating alarms in other people's homes, and because they all used the same frequency band, they had the drawbacks of interference and poor reliability of transmitted and received data.

The present invention solves such conventional problems,
To provide a wireless device that can reliably perform transmission and reception between a parent device and a slave device without causing trouble in setting changes using a switch or malfunction in an apartment complex, and does not cause interference.

Means for Solving the Problems In order to solve the above problems, the wireless device of the present invention includes a slave device registration code storage means stored in advance, and a separate device that rewrites the registration code of the slave device using an arbitrary relational expression. a registration code storage means, a master registration code storage means stored in the master unit in advance, and a slave frequency setting storage means for setting and storing the transmission frequency of the slave unit according to an arbitrary relational expression;
The slave unit includes a master unit storage means for storing the master unit registration code storage means and slave unit frequency setting means;
The master device includes a slave device storage means for storing the two registration code storage means of the slave device, a connecting portion for transmitting the contents of the storage means at the time of initial setting of the slave device and the master device, and , the transmitting/receiving frequency band of the parent device is configured by adjusting means.

Effects According to the present invention, with the above-described configuration, at the time of initial setting, the contents of the registration code storage means of the slave device are stored in advance from the slave device through the connection part in the storage means of the master device, and the contents can be changed according to an arbitrary relational expression. The content of the registration code storage means of the child device is stored, while the content of the registration code storage means of the parent device stored in advance from the parent device through the connection part is stored in the storage device of the child device.
The parent device sets the oscillation frequency of the child device using an arbitrary relational expression, and the set frequency is stored.

In other words, the frequency bands used by the master device and slave devices used in one house in the apartment complex are different from those used by the master device and slave devices used in another house.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. In FIG. 1, the difference from the conventional example is that the control circuit in the slave unit 1 stores the slave unit registration code by using the contents of the slave unit registration code storage notebook 3 stored in advance and an arbitrary relational expression (for example, the serial number). The contents of the separate child device registration code storage means 4 that rewrites and stores the contents of the parent device registration code storage means 20 and the contents of the parent device registration code storage means 20 in the parent device storage means 5 at the time of initial setting, The contents of the oscillation frequency at which the oscillation frequency of the child device is set are stored.
That is, at the time of initial setting, the data is stored in the three storage means of the child device through the connection section 11 as shown in FIG. Note that the oscillation frequency bands of multiple slave devices in a certain house are the same.

On the other hand, in the case of a parent device, the control circuit 1 in the parent device 12
9 contains a pre-stored parent device registration code storage means 20 and an arbitrary relational expression (for example, a serial number).
, the contents of the slave frequency setting storage means 21 for setting and storing the transmission frequency of the slave unit, and the contents of the slave frequency setting storage means 22
The contents of slave device registration code storage means 3 and 4 are stored in . Therefore, at the time of initial setting, connection part 1
1, the data will be stored in the three storage means of the parent device as shown in FIG. Note that the master device stores and retains the contents of the storage means 3, 4, and 5 of a plurality of child devices in an initial setting. In this way, the frequency band used by the master unit and slave units in one home is set arbitrarily when the master unit is initially set up, and the master unit and slave units transmit and receive data in that frequency band, so that the master unit and slave units in other homes can communicate with each other. Unlike the frequency band used by the equipment, interference cannot occur in apartment buildings. That is,
At the time of initial setup, registration codes and transmission frequency bands corresponding to the master unit, multiple slave units are set and stored through the connection section at the time of factory shipment.
With this setting, for example, if a frequency corresponding to each serial number is assigned, interference will not occur. The adjustment means 25 for changing the frequency band used changes the capacitance depending on the voltage applied to the variable capacitance diode in the oscillation circuit 7 of the child device and the local oscillation circuit 16 in the main device 12 shown in FIG. It takes advantage of that fact.

Effects of the Invention As described above, according to the wireless device of the present invention, the following effects can be obtained.

(1) At the time of initial setup, simply by connecting the master device and the slave device, the registration code is automatically set to each home's wireless device through the connection section, eliminating the need for a switch to set the registration code and requiring no troublesome operations. An easy-to-use wireless device can be configured.

(2) In large-scale housing complexes, wireless devices in neighboring houses are distinguished by arbitrarily changing the frequency band used in each house, and the frequency is automatically adjusted to prevent interference. In addition, data reliability is not degraded by unnecessary interference waves (radio waves from other devices in other homes), and data can be reliably transmitted and received between the parent device and the child device.
