Description

[Detailed Description of the Invention] A) Industrial Application Field Is the present invention applicable to ultrasonic waves from the location where it is introduced? This invention relates to a remote control device that remotely controls all electrical equipment as a transmission medium.

口）Prior Art Conventionally, there have been remote control devices that remotely control ventilation fans, electric kettles, and other devices. A wired C binary system, a wireless system, etc. have been proposed.

However, the flexibility between the controller and the electrical equipment was problematic because it required two people (two wirings) and the cost involved.

Also, for those that rely on wireless, and those that use external lines, even if there are only 9 candies controlled in the same room.

Even if I closed the room and tried to control the outlet in the next room, it would be impossible because the infrared rays would be blocked.

In addition, even if it is placed in front of the detection unit (2 W%), the infrared rays will be blocked and it will not work, which greatly hinders the advantages of the remote control.

It's inconvenient. On the other hand, for transmission media that utilizes all radio waves, it is difficult to select the frequency to use due to the possibility of radio wave interference. Generally, the 600MHz2 band is used, but the high frequency of the 300MHz band (2) makes it difficult to design a single circuit and is disadvantageous in terms of cost.Moreover, if the neighbor's house uses the same timer device , there is an extremely high possibility that it will malfunction accidentally.
Since there is always a chance of someone being pranked, safety must be taken to the extreme (2).

Furthermore, as a method that uses the existing power distribution lines inside the house (ri
This is a method that superimposes high-frequency control signals of about 100 KHz on existing power lines (2) and detects and controls them at the outlet.The load on the outlet is 2, for example, a microcomputer or personal computer that is sensitive to noise. If you use all of the above, it is possible that the control signal will malfunction.In addition, if the power transmission line between the house and the house next door is supplied from the same pole transformer, the control signal will be transmitted to the house next door. If both are using the same timer device.

There is a possibility of malfunction. Therefore, it is inferior in terms of safety.

C) Purpose of the Invention The purpose of the present invention is to solve these problems and provide an inexpensive and highly reliable remote control device.

2) Structure of the Invention The present invention uses ultrasonic waves as the signal transmission medium from the controller to the controlled electrical equipment, and uses house structures such as reinforcing bars and icicles as the signal transmission medium.

E) Embodiment FIG. 1 shows the internal structure of the device ζ of the present invention: the controller used, and FIG. 2 shows the control output section used in the present invention.

The control unit in FIG. 1 includes an input unit (11) consisting of a number of keys for giving control commands, an OPU[2+, and a remote control signal based on input information input at the input unit (11 and processed at 0PtJ121). A display section (3) that displays all the output status, etc.;
It consists of an encoder (4) that encodes the remote control signal and an ultrasonic output section (5).

In addition, the control output section shown in FIG.
lO), a decoder (111), a comparator (131) that performs all the comparisons between the encoder αD output and the reference signal from the reference signal source [121], and a comparator (131) that performs all the comparisons between the encoder αD output and the reference signal from the reference signal source [121], It consists of an output control circuit (151) that generates a control signal and a display section (161) that displays the control status.

Then input a series of data such as the code number and output control data of the electrical equipment to be controlled from the input section (1).
,P U (21 + two people.,0PU121,
Analyze this series of data and use it as a control signal.

It is output as parallel data from the output port.

The encoder section (4) converts it into serial data.

The ultrasonic generator (5) generates a control signal modulated by serial data (2).The central processor (2) also generates a control signal modulated by the serial data (2).

It is also possible to create serial data and input it to the ultrasonic generator (5), and it can be selected depending on the performance of the apuf2).

In the control output section of FIG. 2, the ultrasonic control signal modulated by the serial data is received by the ultrasonic receiving section;
Amplify and detect that weak signal.

At the same time, it shapes the waveform and removes all noise components.

Shape into a beautiful waveform. The shaped signal is.

It is input to the decoder section and compared with the data of the reference signal section α2 in the comparator [131, and the input control (i11
It is determined whether the signal specifies the control output section. If specified, output controller α according to control signal C2
In step 5), the controlled electronic device (2) is turned ON or 0FFi, and the entire status display unit (161) is notified by means such as lighting, blinking, or color change of a light emitting diode.

In the present invention, in the case of a single-family house, the pillars of the house are used as the medium for the ultrasonic waves, instead of the air. When air is used as a medium (21) When the room is closed, it is even blocked from the next room by shoji, sliding doors, doors, etc.
Their characteristic acoustic impedance is extremely different from that of air (≦2), so the control signal does not reach the next room due to total reflection.

When the pillars are used as a medium, the characteristic acoustic impedance is considered to be the same, and the reflection of the control signal due to the mismatch ζ2 at the joints between the pillars is also considered, but since the pillars are firmly connected to each other, This means that there is no total reflection and the control signal is reliably transmitted.

Second, the number of cycles of use is 40 K Hz ~ 40 KHz for wooden structures, based on experiment C2, because of the difference in characteristic acoustic impedance between wooden structures and reinforcing bars. 60 KHz, frequency for reinforcing steel! Good results were obtained between 4100 KHz and 500 KHz.

Therefore, in order to give a control command from the direct control unit force λ to the control output unit, what is the ultrasonic generation unit of the control unit? When the two pillars of the house come into contact with each other (2. The ultrasonic receiving section (10) of the control output section), the hand C binary value when the two pillars C come into contact with the entire line is executed.

f) Effects of the Invention According to the present invention, by simply attaching the control f4 part to the pillar of the house, even if one room is closed, it is free as long as it is in the same house.
It is possible to control any controlled electronic device 6. Also, if you are using it in a single-family home, there is no need to worry about interference even if your neighbor's house uses the same system.
Furthermore, since a power supply or distribution line is not used as a signal transmission medium, low-cost and highly reliable remote control is possible.
