Abstract

PROBLEM TO BE SOLVED: To obtain a plurality of control signals at the same time by using magnetic bricks or clay magnets as magnetic recording media and guiding a person or vehicle equipped with a magnetic information sensing device by a guide path side guide consisting of a road surface or wall surface where the magnetic recording media are laid. SOLUTION: The magnetic recording media are formed by magnetizing the surfaces of the magnetic bricks or clay magnets into the S and N poles and the person or vehicle equipped with the magnetic information sensing device is guided by the guide path side guide consisting of the road surface or wall surface where the magnetic recording media are laid. For example, the person which moves as shown by an arrow keeps on moving by sending magnetic information S0N (0: unmagnetized layer) recorded in the onward bricks 5, but once magnetic information N0N recorded in an attention brick 5 is sensed, the moving speed is reduced and when magnetic information N0S recorded in a stop block 7 is sensed, the person stops. Consequently, the blind, for example, can know his or her present position.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention allows a person or a vehicle equipped with a magnetic information sensing device to enter a predetermined area in which a magnetic recording block having magnetic information is laid, so that a plurality of control signals are transmitted once. The present invention relates to a magnetic recording block guide device.

2. Description of the Related Art Conventionally, as means for providing various kinds of information regarding guidance of passersby, for example, cable broadcasting, radio waves, NEC
A method using a visually impaired guidance system made by environmental engineering is known.

In wired broadcasting, speakers connected by wires are arranged at predetermined intervals, and audio information from the ground station is flown through the speakers. In the case of radio waves, a passerby carrying a receiver receives the radio wave information transmitted from a transmitter installed in the guide device by the receiver when necessary. In addition, the method using the NEC Environmental Engineering guidance system for the visually impaired allows a passerby to use a soft magnetic material detection stick while following a guide made of a soft magnetic material laid on the road surface or a guide equipped with an AC power generator. Get informed.

Conventionally, as a means for providing various kinds of information regarding guidance of a passing vehicle, for example, a method using radio waves or paint applied to the road surface is known.

As for radio waves, a passing vehicle carrying a receiver receives radio wave information transmitted from a transmitter installed in a guide device by the receiver when necessary. Characters or symbols created by applying paints of various colors on the road surface are read by a vehicle driver or a symbol reading device to obtain road surface information.

[0006]

As described above, since cable broadcasting provides information to an unspecified number of people by using sound waves, when sound waves are blocked or reflected by obstacles, Often no information is available,
For example, route guidance information by a sound wave at an intersection for a visually handicapped person also causes a traffic accident due to absorption, reflection, and refraction of the sound wave by the obstacle.

Further, the means for transmitting information to pedestrians and vehicles by radio waves is, in particular, an underpass or a tunnel, because when the radio waves propagate, absorption, reflection and refraction of the radio waves occur due to obstacles. , It is difficult to effectively exhibit its performance in a large building.

[0008] Further, in the method using the NEC Environmental Engineering system for guiding visually impaired persons, a method of forming a road surface guide with a soft magnetic material and obtaining information while following the guide with a soft magnetic material detecting cane ,simply,
It only senses whether a soft magnetic material is laid there, and no further information can be obtained. In addition, the method of inducing with an AC current generator laid on the road surface is difficult to use in a place where power supply is difficult to obtain, and the construction cost,
A large amount of electricity and other costs are required.

Further, the method of obtaining road surface information from characters or symbols prepared by applying paints of various colors on the road surface has a problem that the period of use is very short due to dirt, abrasion, deformation, etc. of the road surface. Is being watched.

[0010]

In order to achieve the above object, the present invention provides a magnetic brick which is inexpensive to manufacture, has a high coercive force, is excellent in bending strength and abrasion resistance, and is also water absorbent. Alternatively, a clay magnet is used as a magnetic recording medium, and a guide path side guide including a road surface or a wall surface on which a magnetic recording block formed by joining the clay magnets is laid is provided.

Further, according to the present invention, a magnetic information sensing device constructed by combining one or several magnetic sensors detects magnetic recording when passing over a magnetic recording block and outputs a plurality of control signals at a time. Since it can be generated, this control signal enables everything from a lightweight cane that sounds several buzzers with different tones, playback as voice, and speed control of the vehicle by microcomputer control. .

[0012]

According to such a magnetic recording block guide device, various kinds of information can be obtained by causing no radio wave or sound wave interference and passing through a guideway side guide for recording and storing a large amount of information as magnetic information. Things are possible. For example, in the case of a blind person, it is possible to know where he is by reading the magnetic information buried in the sidewalk.

Further, a vehicle passing a road on which a guideway side guide is laid can detect the presence of an obstacle such as a pedestrian crossing or an obstacle nearby from the magnetic information recording of the laid magnetic recording block. .

Further, a vehicle passing through the road on which the guideway side guide is laid can be automatically driven by the magnetic information of the laid magnetic recording block. For example, a vehicle equipped with a magnetic sensor and a control device such as a drive control motor is capable of consistent automatic driving from start to acceleration, deceleration, and stop by a magnetic guidance device.

FIG. 2 shows a magnetic sensor Hall IC of the present invention.
FIG. 2 is a laying view of the magnetic recording block created in FIG. 1 as an example of a guideway side guide for a vehicle. Now, a passerby traveling in the traveling direction of FIG. 2 senses the magnetic information S0N (where 0 means a non-magnetized layer) recorded in the traveling block 5 and continues traveling, but in the caution block 6 When the recorded magnetic information N0N is sensed, the traveling speed is reduced, and when the recorded magnetic information N0S is sensed in the stop block 7, it is stopped.

The micro switch of (3) operates to form the circuit shown in FIG. 3B, and the magnetic information of the magnetic recording block is read. In the example, the magnetic information of the magnetic recording block of FIG. 2 magnetized to about 200 gauss was accurately read and operated. When the return path is followed, the return path microswitch 13 operates to perform the same operation.

FIG. 4 is a block diagram using the magnetic sensor Hall IC of FIG. In this embodiment, a photocoupler is used, and the output signal thereof is input to the input of the microcomputer to control the generation of three types of sounds having different timbres. However, control is
It is also possible to control the generation of sound.

The Hall IC used as the magnetic sensor of this embodiment has a characteristic that it is turned on by the S pole of the magnetic pole.
The operating current is weak. In order to further reduce the weight, a reed switch can be used as the magnetic sensor, so that the magnetic sensor can be extremely miniaturized. However, in this case, since the difference between the S pole and the N pole of the magnetic pole cannot be detected, the magnetization method of the magnetic recording block of the guide path side guide in FIG. 2 must be changed.
