Description

Description: TECHNICAL FIELD The present invention relates to a signal transmission system for a deaf school dormitory, which is suitable for being installed in a dormitory school dormitory.

(Prior Art) Many deaf schools have a dormitory to accommodate students. In this way, when accommodating students who are deaf in a school dormitory, it is necessary to observe discipline.Therefore, signals from events starting from waking up in the morning to going to bed at night should be signaled. become. As the signal, since the target person is a deaf person, the signal has been conventionally exclusively emitted by a light emitting means such as a lamp.

(Problems to be solved by the invention) However, in the method of signaling a deaf student by a lamp or the like as described above, when the signal is given, the student happens to be sleeping or not sleeping. But if you are not paying attention to the lamp, the signal will not be communicated to the students. The present invention has been made in view of this point, and is a bed pad (a bed pad to be laid on a mattress of a bed, which is used when a student is sitting or lying when in a room, and is not actually used). 61-140692
No. gazette, Japanese Utility Model Publication No. 63-5788 gazette) or a human body mounted object such as a chair is equipped with a vibration unit, and the waveform of the signal applied to this vibration unit is changed in various ways so that the user can experience the visual sensation regardless of the visual sense. The problem to be solved is to obtain a system for transmitting a signal.

(Means for Solving the Problem) As a means for solving the above problems, the present invention provides a repetitive signal composed of a plurality of types of waveforms suitable for transmission of various contents and a repetitive signal for different emergencies to a body vibration. A signal generating means for generating at a suitable low frequency, a selecting means for selecting a signal having a required waveform from among a plurality of types of signals emitted by the signal generating means, and the emergency means prior to the selecting means. A fire alarm circuit for repeatedly outputting a signal, an amplifier for amplifying a signal generated by the signal generating means, and a vibration unit for vibrating a human body placing object such as a bed pad in response to an output signal of the amplifier. And As the selecting means, a changeover switch or a timer device is specifically used.

(Operation) Since the present invention is configured as described above, various contents such as getting up and going to bed (in addition to eating, learning, roll call, bathing, etc.)
Various waveforms are prepared, and when the vibrating unit is repeatedly vibrated by the signal based on these waveforms and the user feels it, the contents of the transmission can be easily grasped, and the information is surely transmitted if it is placed on a chair or bed. be able to. Moreover, since the fire alarm selects and transmits the emergency signal in preference to the above signal, it is possible to prevent information leakage in an emergency even when the information is transmitted by the above-mentioned signal.

(Example) An example of the present invention will be described below with reference to FIG.
Reference numeral 1 is a signal generator serving as a signal generating means, which is a waveform suitable for each signal of waking up and going to bed (other than meal, learning, roll call, bathing, etc.) and a signal at the time of fire (details will be described later However, basically, two signals having different frequencies are prepared, and these signals are individually or alternately generated to obtain a large number of signals) and output to the amplifiers 2 and 3. . The amplifiers 2 and 3 have different output values, and the number of bed pads 4 and 5 (which may be chairs) accommodating a plurality of vibration units (not shown) connected as loads are different. .

The signal generator 1 has a terminal that outputs the selected signal as it is. Light-emitting diodes 8 and 9 are connected to this line via amplifiers 6 and 7, and a display lamp 12 is connected via amplifiers 10 and 11. , 13 are connected. The light emitting diodes 8 and 9 are attached to each bed one by one, and the display lamps 12 and 13 are attached to each room containing a plurality of beds. The light emitting diodes 8 and 9 and the display lamps 12 and 13 visually transmit signals to deaf students as in the conventional case.

To the control side of the signal generator 1, a changeover switch 14 as a signal selecting means is connected so that an appropriate one can be arbitrarily selected from the signals having various waveforms generated by the signal generator 1. There is. The control side of the signal generator 1 is further provided with a timer device 15 which is a timer means for automatically performing signal selection according to the passage of time, and an emergency waveform signal regardless of the operation of the timer device 15 during a fire. The fire alarm circuit 16 for generating
The connection circuit described above establishes a signal transmission system for the deaf school dormitory, but this system is deaf, but in order to give the deaf person the possibility of transmitting music or speech, mixing to the input side is possible. An amplifier 17 is connected, and the vibration unit is made to vibrate by the music taken in from the microphone 18, the record player 19, the cassette deck 20, and the like.

As the vibration unit in the above circuit, various types such as solenoid type, electrokinetic conversion type, or motor drive type can be considered. However, in response to various changing signals including music, A so-called electrokinetic conversion type mechanism is adopted as a device that obtains vibrations suitable for strength and weakness. This is to obtain vibration by a magnetic interference action when electricity is applied to a magnet and a coil wound near the magnet. According to the vibrating unit having this structure, unlike the other vibrating units, the response and the waveform reproducibility can be remarkably improved.

Next, various waveforms will be described. As described above, the types of signals include an emergency signal such as getting up, going to bed (in addition to meals, learning, roll call, bathing, etc.) and fire. Of these, the waveform as the wake-up signal is, as shown in Fig. 2, a signal of 47Hz (hereinafter referred to as "A signal") and a signal of 35Hz (hereinafter referred to as "B signal") after two beats. For 2 beats, and after a certain time, the B signal is output twice for 2 beats (3 times in total), and this is repeated 4 times to move to the next,
Then, after outputting the A signal for 3 beats, and after a short period of time, outputting the B signal for 3 beats 3 times is repeated 4 times, and further shifts to the A signal for 4 beats, followed by the B signal for 4 beats each. A method in which after outputting six times and then pausing and repeating the above steps after pausing, a good result was obtained as a wake-up signal as a result of the experiment.

Next, as the waveform of the sleeping (sleeping) signal, as shown in FIG. 2, the A signal and the B signal are alternated, and these are attenuated so that they are initially large and then gradually weakened. It has been proved that the sleep-inducing effect is high, but as shown by, only the B signal is used, and the output value of this B signal is changed in magnitude depending on the passage of time, and the one in which this is repeated multiple times has a good sleep-inducing effect. Has been confirmed as something that can be obtained.

What is shown in FIG. 2 is an emergency signal used to evacuate in an emergency such as a fire. This emergency signal requires a fairly violent vibration because it must reliably signal an emergency even when the deaf student has a deep sleep. However, it does not have to be mere rupture, but it must have excellent stimulating ability. Therefore, it is preferable that the A signal and the B signal are alternately and continuously output, and a waveform as shown in the figure is adopted.

Next, an example of a circuit for obtaining the AB signals having the various waveforms will be described. 3 shows a specific circuit of the signal generator 1, 21 is a voltage controlled oscillator, and 22 is a voltage controlled amplifier which receives and amplifies the output signal of the voltage controlled oscillator 21. The voltage controlled oscillator 21 operates by receiving the frequency control output, and the voltage controlled amplifier 22 operates by receiving the envelope control output. These frequency control output and envelope control output can be obtained by the circuits shown in FIGS. 4 to 7 depending on the type of wake-up, sleeping (two types), and emergency signal.

Are connected and formed as shown in the figure through OR gates 29 and 30 and NAND gate 31. The selection of the waveforms indicated by and in FIG. 2 is performed by switching the analog switch 28.

What is shown in FIG. 5 is an example of a circuit for obtaining the waveform of the sleep signal shown by in FIG. In this circuit, an operational amplifier 32 and a flip-flop circuit 33 are connected as shown in the figure. The negative feedback resistor 34 of the free-running multivibrator by the operational amplifier 32 is shorted with a diode 35 to shorten the rise time. A waveform obtained by dividing the frequency by a wave oscillator and a frequency dividing circuit by the flip-flop circuit 33 is obtained, and an envelope control output and a frequency control output as shown in the figure are obtained. Sixth
The one shown in the figure is a simplified version of the one shown in FIG. 5, and an output waveform as shown in the figure can be obtained from which a sleep (sleeping) signal as shown in FIG. 2 can be obtained.

The one shown in FIG. 7 is for obtaining the emergency signal shown in FIG. In this circuit, the output of the clock oscillator 36 is directly used as the frequency control output, and the output of the decimal counter 37 with a decoder is obtained as the envelope control output through the NOR gate 38.

The circuits shown in FIGS. 4 to 7 are connected in parallel inside the signal generator 1 shown in FIG.
The circuit shown in the figure is selected and operated by changing over by the changeover switch 14 or the timer device 15. The emergency circuit of FIG. 7 is independent of the above selections and has priority over the others in an emergency. Although explanation is omitted, meals, learning,
For roll call, bathing, etc., a signal having a waveform that gives the feeling is generated and used.

FIG. 8 shows a concrete circuit of the amplifiers 6 and 7 and the light emitting diodes 8 and 9 shown in FIG. To explain this with different reference numerals for convenience, 39 is a power amplifier which receives the envelope control output and turns on the red light emitting diode 40 and the green light emitting diode 41. The red light emitting diode 40 lights up when an A signal having a high frequency is emitted, and the green light emitting diode 41 emits light when receiving a B signal having a low frequency. Transistors 42 and 43 for controlling energization by receiving a frequency control output are connected to these light emitting diodes 40 and 41, and an inverter 44
So that they are not turned on at the same time.
