[DESCRIPTION]
[invention Title]
ALARM SYSTEM FOR TRAIN ACCESS USING BONE CONDUCTION SPEAKER AND METHOD THEREOF
[Technical Field]
The present invention relates, in general, to a system and method for providing an alarm signaling the approach of a train using a bone conduction speaker, and, more particularly, to a system and method for providing an alarm signaling the approach of a train using a bone conduction speaker, which output a vibrating sound for an alarm when a train is approaching ahead of a maintainer by a predetermined distance in order to prevent fatal and injurious accidents from occurring to the maintainer in the case where the maintainer is conducting maintenance work on a track or signal equipment on the track side of a railway, thus preventing accidents from occurring by allowing the maintainer to cope with dangerous situations .
[Background Art] Generally, when a maintainer conducts maintenance work on a track or signal equipment on the track side of a railway, as one method of securing the safety of the maintainer, safety alarm providers are placed ahead of and behind a work site on the track side by a predetermined distance, separately from the maintainer, in order to prevent collision accidents with a train.
At this time, safety alarm providers monitor whether a train is approaching the work site on the track side, and notifies the maintainer of the approach of the train when the approach of the train is sensed.
For example, such a safety alarm provider transfers information about the approach of a train to the maintainer using hand signals with a flag in the daytime, and using hand signals with a warning lamp at nighttime.
Even though an alarm signaling the approach of a train is provided by safety alarm providers placed ahead of and behind the work site on the track side by a predetermined distance, the maintainer, who is continuously conducting monotonous maintenance work for a long period of time, has his or her senses dulled, and is not aware of an alarm signal from the safety alarm provider as indicated by a flag or a warning lamp, so that the maintainer cannot be aware of the approach of a train even when the train is actually approaching close to the work site, thus causing fatal and injurious accidents attributable to a collision with the train.
In particular, there are problems in that, since the maintainer must be continuously aware of the hand signals from the safety alarm providers even during the conduction of maintenance work, the efficiency of the maintenance work is deteriorated, and in that, since a plurality of safety alarm providers, that is, separate safety personnel, must be placed in addition to the maintainer, personnel expenses are increased.
Further, there is a problem in that, even though safety alarm providers must also continuously monitor the approach of a train, he or she cannot accurately transfer information about whether a train is approaching due to the dulling of the senses, such as the deterioration of his or her powers of concentration, thus making it impossible to provide reliable information about whether a train is approaching.
Furthermore, there is an additional problem in that, in an area where there is serious noise, it is difficult to be aware of an alarm signal from a safety alarm provider, thus further increasing the risk of a collision with a train.
[Disclosure] [Technical Problem]
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a system and method for providing an alarm signaling the approach of a train using a bone conduction speaker, which allow maintainers, who are maintaining a track or signal equipment on the track side of a railway, to be aware of the approach of a train and cope with dangerous situations even though the maintainers have had their senses dulled by continuously conducting monotonous maintenance work for a long period of time.
Another object of the present invention is to provide a system and method for providing an alarm signaling the approach of a train using a bone conduction speaker, which do not require safety alarm providers for securing the safety of maintainers who are maintaining a track or signal equipment on the track side of a railway, or which minimize the number of safety alarm providers, thus minimizing personnel expenses required for maintenance and easily recognizing whether a train is approaching even in an area where there is serious noise.
[Technical Solution]
In order to accomplish the above objects, the present invention provides a system for providing an alarm signaling an approach of a train using a bone conduction speaker, comprising a signal transmitter installed on a train and configured to transmit a train approach signal in a wireless manner; a signal receiver worn by a maintainer, who is conducting maintenance work at a track side work site, and configured to receive the train approach signal when the signal transmitter approaches within a range capable of being sensed; and a bone conduction speaker configured to output a vibrating sound indicating the approach of a train when the signal receiver receives the train approach signal.
In this case, the signal receiver and the bone conduction speaker are attached to a helmet of the maintainer .
Meanwhile, the signal transmitter comprises a signal generation unit for generating the train approach signal, and a signal transmission unit for transmitting the train approach signal generated by the signal generation unit in a wireless manner.
Further, the signal receiver comprises a signal reception unit for receiving the train approach signal transmitted from the signal transmitter in a wireless manner, and a signal control unit for performing control such that an alarm sound generated due to the approach of the train is output through the bone conduction speaker when the train approach signal is received through the signal reception unit.
Further, the present invention provides a method of providing an alarm signaling an approach of a train using a bone conduction speaker, comprising the steps of receiving a train approach signal when a train, on which a signal transmitter for transmitting the train approach signal in a wireless manner is installed, approaches within a range capable of being sensed; and outputting an alarm sound by controlling a bone conduction speaker so as to indicate the approach of the train when the train approach signal is received.
In this case, the bone conduction speaker is attached to a helmet worn by a maintainer who is conducting maintenance work at a track side work site.
[Advantageous Effects] According to the present invention, there is an advantage in that, when a maintainer conducts maintenance work on a track or signal equipment on the track side of a railway, alarm information signaling the approach of a train can be accurately and rapidly perceived in a track side work site in which maintenance is being conducted, thus remarkably reducing the occurrence of fatal and injurious accidents attributable to a collision with a train.
In particular, whether a train is approaching can be accurately perceived even in a work site where there is serious noise by using a bone conduction speaker, and the occurrence of collision accidents with a train can be remarkably reduced by generating an alarm sound regardless of whether a train is approaching ahead of or behind the work site. Further, there is an advantage in that, since a method using a bone conduction speaker is utilized, the ears of a maintainer are not covered, so that the maintainer can immediately hear an alarm sound indicating the approach of a train without experiencing difficulty in conducting the maintenance work, and the worker does not need to wear or install separate equipment in addition to the currently worn safety helmet, thus greatly improving the convenience of use. In addition, there is an additional advantage in that, since separate safety alarm providers for determining and monitoring whether a train is approaching and transferring the results of monitoring to maintainers are not required, or since the number of safety alarm providers is minimized, expenses required for maintenance can be reduced .

[Best Mode] Hereinafter, the features of a system and method for providing an alarm signaling the approach of a train according to the present invention will be understood through embodiments which will be described in detail with reference to the attached drawings. FIG. 1 is a diagram showing the construction of a system for providing an alarm signaling the approach of a train using a bone conduction speaker according to the present invention, FIG. 2 is a detailed block diagram showing the system for providing an alarm signaling the approach of a train using a bone conduction speaker according to the present invention, FIG. 3 is a diagram showing a bone conduction speaker according to the present invention, FIG. 4 is a diagram showing the state of wearing bone conduction speaker according to the present invention; and FIG. 5 is a control flowchart showing a process for providing an alarm signaling the approach of a train using a bone conduction speaker according to the present invention.
First, referring to FIGS. 1 to 4, a system for providing an alarm signaling the approach of a train using a bone conduction speaker according to the present invention is a safety equipment system for reducing the fatal and injurious accidents occurring when a maintainer is not aware of the approach of a train 2 due to the dulling of the senses while maintenance work on a track or signal equipment on the track side 1 of a railway is being conducted .
The above-described system for providing an alarm signaling the approach of a train using a bone conduction speaker according to the present invention includes a signal transmitter 100 installed on the train 2 approaching a track side work site 10, at which a track or signal equipment requiring maintenance work is installed, and configured to transmit a train approach signal in a wireless manner, a signal receiver 200 worn by a maintainer who conducts maintenance work at the track side work site 10 and configured to receive the train approach signal transmitted from the signal transmitter 100 when the signal transmitter 100 approaches within a range capable of being sensed, and a bone conduction speaker 300 configured to output information about the approach of a train to the maintainer in the form of a vibrating sound in response to the train approach signal received from the signal receiver 200.
Hereinafter, the construction of the system for providing an alarm signaling the approach of a train using a bone conduction speaker according to the present invention is described in detail.
First, the signal transmitter 100 is provided in the train 2, which is approaching the track side work site 10, and is configured to transmit a train approach signal having a predetermined frequency in a wireless manner so as to secure the safety of the maintainer. The signal transmitter 100 includes a signal generation unit 110 for generating a train approach signal and a signal transmission unit 120 for transmitting the train approach signal generated by the signal generation unit 110 in a wireless manner.
In this case, the signal generation unit 110 may be preferably implemented as a microcomputer having internal memory capable of storing data about the train approach signal indicating that a train is approaching.
Further, the signal transmission unit 120 is configured to transmit the train approach signal, consistently generated by the signal generation unit 110 installed on the train, in a wireless manner, and may be implemented as a well-known wireless transmission module. Meanwhile, the signal receiver 200 and the bone conduction speaker 300 are attached to the helmet 400 of the maintainer.
In this case, the signal receiver 200 is configured to receive a train approach signal having a predetermined frequency in a wireless manner from the train 2, which is approaching the track side work site 10, in order to secure the safety of the maintainer. The signal receiver 20 includes a signal reception unit 210 for receiving the train approach signal, which has been transmitted from the signal transmitter 100 in a wireless manner, and a signal control unit 220 for performing control such that an alarm sound generated due to the approach of the train is output to the bone conduction speaker 300 when the train approach signal is received through the signal reception unit 210.
Of course, the signal reception unit 210 is configured to receive the train approach signal when the train 2 approaches within a range capable of being sensed, and may be implemented as a well-known wireless reception module .
Therefore, the signal transmitter 100 installed on the train 2 continuously transmits a train approach signal . When the signal receiver 200 attached to the safety helmet 400 of the maintainer senses the train approach signal, it generates an alarm sound toward the maintainer through the bone conduction speaker 300, thus notifying the maintainer of the approach of a train.
In this case, since it is also possible to receive a train approach signal from an opposite train 2 approaching along an opposite track, the maintainer can be aware of whether the train 2 is approaching the current work site at any location on the track.
Meanwhile, the bone conduction speaker 300 outputs an alarm sound to the maintainer under the control of the signal control unit 220 of the signal receiver 200, thus allowing the maintainer to be evacuated to a safe region before the train approaches.
Such a bone conduction speaker 300 uses the principle by which a human being hears sound through the vibration of the cranial bone, and is a well-known component which is generally commercialized.
In particular, the bone conduction speaker 300 needs to be attached to a portion 3 around the ear. For example, the bone conduction speaker 300 may be attached to any portions of the safety helmet 400 in such a way that it is attached to the bottom of the safety helmet 400, thus covering the portion around the ear, or in such a way that it is attached to the safety helmet 400 itself, thus enabling a portion protruding from the bottom of the safety helmet 400 to be omitted. Accordingly, since a headset does not cover the ear, the maintainer has no difficulty in hearing other sounds. Further, the sense of hearing is not influenced even though the maintainer wears the bone conduction speaker 300 for a long period of time. Even in a noisy environment, it is possible to be aware of an alarm sound against the approach of a train. Therefore, the present invention is implemented such that the signal receiver 200 and the bone conduction speaker 300 are integrated into an existing typical safety helmet 400.
The above-described bone conduction speaker 300 is preferably manufactured in a shape capable of covering the portion 3 around the ear, as shown in FIG. 3, and is then fixedly attached to the helmet.
Hereinafter, a control process for providing an alarm signaling the approach of a train using a bone conduction speaker according to the present invention is described in detail with reference to FIGS. 1 to 5.
First, the train 2 moving along the track transmits a train approach signal through the signal transmitter 100 in a wireless manner at step SlOO. The train is moving while continuously transmitting the train approach signal in a wireless manner at step SlOO . When the moving train 2 approaches the track side work site 10 at which a track or signal equipment, requiring maintenance work or currently being maintained, is installed, the train approach signal is received through the signal receiver 200 mounted on the helmet 400 of the maintainer placed at the track side work site 10 at step SIlO.
When the train approach signal is received, the signal receiver 200 outputs an alarm sound by controlling the bone conduction speaker 300 so as to indicate the approach of the train, thus allowing the maintainer placed in the track side work site 10 to be aware of the approach of the train at step S120, at which the maintainer, having been aware of the alarm sound, can escape from the track side work site 10 or can rapidly cope with the dangerous situation.
Therefore, even if the maintainer has his or her senses dulled due to the conduction of the work, such as maintenance work conducted on the track side for a long period of time, the maintainer can accurately and rapidly determine whether the train is approaching in the track side work site 10, thus preventing fatal and injurious accidents from occurring due to a collision with the train 2. In particular, even in the track side work site 10 where there is serious noise, an alarm sound can be accurately sensed, thus further decreasing the occurrence of the risk of a collision with a train.
Although the preferred embodiments of the present invention have been disclosed, the scope of the present invention is not limited to the above embodiments, and extends to the substantial equivalents thereof, and thus various modifications can be implemented by those skilled in the art, without departing from the scope and spirit of the invention.
