Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram of a vibration switch according to the present invention, and FIG. 2 is a perspective view of a cable-type vibration sensor of the vibration switch.

As shown in FIG. 1, a vibration switch A according to the present invention has a sensor section 1 which is a vibration sensor for detecting vibration, and a signal which is a signal processing section for processing a signal inputted from the sensor section 1. And a processing unit 2. The sensor section 1 includes a detection member 3 and a cable-type vibration sensor 5.

The cable-type vibration sensor 5 includes a vibration detection cable 5A.
As shown in FIG. 2, a conductive core wire 5a and an insulating layer 5b made of a piezoelectric member, for example, a piezoelectric plastic, etc.
And a shield layer 5c having conductivity, and an outer coating layer 5d having insulation properties.

The vibration detection cable 5A has a core wire 5a and a shield layer 5c at one end, which is the terminal end, of 1M.
1M, which is connected via a terminating resistor 4 of about .OMEGA.
It is connected to the other end of the pull-up resistor 6 of about Ω.
When the cable-type vibration sensor 5 vibrates due to an external force applied thereto, the piezoelectric layer 5b converts the energy of the vibration into electric energy to generate an electric signal.

If there is no vibration, the potential at one end of the pull-up resistor 6 is a DC potential that is approximately 1/2 of the power supply voltage obtained by dividing the power supply voltage by the two resistors 4 and 6. The potential on the other end of the pull-up resistor 6 fluctuates. When the cable vibration sensor 5 is disconnected, the potential on the other end of the pull-up resistor 6 rises to the power supply voltage.

Then, the cable type vibration sensor 5 is
As shown in FIG. 5, the detection member 3 is fixed by a stopper 7 so as to be in contact with the wooden or synthetic resin plate-like detection member 3, and when the detection member 3 is hit, the vibration is caused by a cable vibration. The signal is transmitted to the sensor 5. It is desirable that the cable-type vibration sensor 5 is fixed to the back side of the detection member 3 so that the cable-type vibration sensor 5 is not directly touched and deteriorated as shown in FIG.

As shown in FIG. 3, the signal processing unit 2 amplifies a signal (waveform signal) detected by the cable vibration sensor 5 and a signal S amplified by the amplifying circuit 8.
And a microcomputer 10 for processing the signal S.

Therefore, the waveform signal detected by the cable type vibration sensor 5 and input to the signal processing section 2 is amplified to an appropriate level by the amplifier circuit 8, and after noise and the like are removed by the filter 9, The processing is performed by the microcomputer 10. After the processing, when it is determined that the input signal is artificial, the signal processing unit 2 issues an output signal for an alarm or the like.

The criteria used by the microcomputer 10 for the judgment include the signal level and the signal duration. For example, if the reference of the signal level is set lower, the sensitivity is improved, so that a system that operates reliably in an emergency can be constructed.

FIG. 5 shows an example in which the vibration switch A according to the present invention is installed in a corridor in a hospital. The sensor unit 1 of the vibration switch A is installed on both sides or one side of the corridor at a height where a person can reach. If the height of the installation is about the height of the waist of the person, the vibration switch A can be used as a handrail and can be operated from a wheelchair.

If the detection member 3 is installed at the height of the waist of a person, the detection member 3 can be used not only as an emergency switch but also as a handrail in a corridor or a staircase. In this case, both a vibration that strikes the detection member 3 for the purpose of operating the emergency switch and a vibration that occurs when a person passing through the corridor or stairs touches as a handrail occur, and both signals are generated. The signal is input to the signal processing unit 2.

However, the vibration generated when a person hits the detection member 3 for the purpose of operating the vibration switch A is larger than the vibration when a person touches the detection member 3 as a handrail. Utilizing this, the vibration switch A can be operated only when a person hits the discrimination of these two signals.

Further, the signals of the two members can also be distinguished by making the structure of the detection member 3 as shown in FIGS. 6 (a) to 6 (d).

As shown in FIG. 6A, when a person has a handrail, the upper part of the handrail is used. It is made of a material having high properties so that vibration is hardly transmitted to the cable vibration sensor 5. The lower half 3B, which is the vibration detection portion of the detection member 3, is used as a component of the vibration switch A, and is made of a material such as a wooden board or a metal plate to which vibration is easily transmitted. Then, the upper and lower halves 3A and 3B of the detection shaped member 3 are installed on the wall (installation surface) 12 by columns 11A and 11B, respectively. Lower half 3 of shape member 3 for detection
In order to use B as a component of the vibration switch A, a cable-type vibration sensor 5 is arranged behind the lower half 3B.

With the detection member 3 having such a structure, vibration when the lower half 3B of the detection member 3 is hit is transmitted, and vibration generated when a person touches as a handrail. Is absorbed by the upper half 3A of the detecting member 3 and is not transmitted to the cable-type vibration sensor 5;
The signal processing unit 2 is provided with the vibration switch A originally intended.
Only the vibration for operating can be input.

This is because, as shown in FIG. 6B, the detecting member 3 is made of a single material such as wood or metal which is easy to transmit vibration. Upper half 3
It can also be realized by covering only A with a cover 13 made of a material such as a sponge which easily absorbs vibration.

The same object can be achieved by a structure as shown in FIG. That is, the upper half 3 used as a handrail portion uses the structure of the detection shaped member 3.
A and a lower part 3B used as a constituent member (vibration detection part) of the vibration switch A, and a cable vibration sensor 5 is attached to the back side of the lower part 3B. Then, the upper half 3A and the lower half 3B are partially connected to each other by the relay rods 14 so that the vibration to the upper half 3A of the detecting member 3 is not transmitted to the lower half 3B. When the upper half 3A is touched, the vibration is less likely to be transmitted to the signal processor 2 of the vibration switch A. In this case, the upper and lower halves 3A and 3B of the detection shape member 3
It is installed on the wall (installation surface) 12 by 5A and 15B.

Alternatively, the shape of the detection member 3 is changed to the shape shown in FIG.
As shown in (d), only the upper half 3A is fixed to the wall surface (installation surface) 12 by the support 16 and the shape of the lower half 3B is made to have an inverted L-shaped section. Wall 12
, And the cable-type vibration sensor 5 is arranged behind the lower half 3B.

With this structure, when the lower half 3B of the detecting member 3 is hit, the lower projection 17 of the lower half 3B collides against the wall surface 12, and strong vibration is generated by the cable vibration sensor 5.
It will be transmitted to. Thereby, it is possible to more easily determine the signal generated when the detection member 3 is hit as a switch and the signal generated when the detection member 3 is touched as a handrail.

Instead of attaching the cable-type vibration sensor 5 to the detection member 3 as described above, the cable-type vibration sensor 5 is embedded in a wall surface, and a mark is placed on the wall surface so that its position can be recognized. Sometimes, the vibration switch A may be operated by hitting a wall surface.

Next, an example of use having a security function that allows only a specific person to operate the vibration switch A will be described with reference to FIG.

When it is desired to give the right to operate the vibration switch A only to a specific person, for example, when it is necessary to judge the administrator to stop the specific device, the person who gives the right can use the specific jig. This can be realized by forming

As a jig, a jig having a vibration waveform different from that when struck by a human hand, such as a metal rod, is used. A waveform when a vibration is applied to the detection forming member 3 using this jig is input to the signal processing unit 2 in advance, and the characteristics of the waveform are stored in a storage device 18 as storage means attached to the signal processing unit 2. To memorize it. The characteristic of the waveform stored in the storage device 18 is compared with the characteristic of the input waveform, and the vibration switch A is operated only when the two coincide with each other. Only can be reacted.

As shown in FIG. 7, the number of output signals 1, 2,... N of the vibration switch A according to the present invention may be plural. When a plurality of types of vibration waveforms when a vibration is applied by a specific jig or a pattern of hitting the detection forming member 3 are stored in the storage device 18, and a waveform that matches the stored waveform pattern is input. ,... N output in advance with respect to the waveform pattern.

In particular, since the cable type vibration sensor 5 outputs a vibration waveform having an amplitude depending on the tapping strength, it is possible to output different output signals in accordance with the tapping strength to perform different processing. it can. For example, it is used as a switch such as a lighting fixture capable of continuously adjusting the brightness. When the brightness is particularly desired, the vibration switch A is strongly hit, and when the brightness is small, the vibration switch A is strongly hit. It can be used.
