Description

{Disaster prevention platform based on location information of workers and heavy equipment}

The present invention relates to a disaster prevention platform based on worker and heavy equipment location information, and more specifically, to a system that enables workers to detect heavy equipment through their hard hats around a construction site, thereby ensuring the safety of workers.

At construction sites or industrial sites, there are always risks from machinery, equipment, and facilities, risks from electric shock, risks from fire and explosion, risks from collapse and falling objects, and risks from hazardous substances. Accordingly, safety for workers is essential.

However, since workers are engrossed in their work, there is always a possibility that dangerous situations and accidents can occur. Therefore, construction sites and industrial sites have industrial safety signs installed to notify workers in advance when they approach a dangerous element, in order to prevent accidents.

Meanwhile, various pedestrians may pass around the construction site. Among these pedestrians, workers may also be included. In particular, workers may be vulnerable to safety around the construction site, so separate measures are needed. Therefore, measures to ensure the safety of workers are being devised.

Korean Patent No. 10-1112760

The present invention is intended to solve the problems of the prior art as described above, and its purpose is to detect heavy equipment being moved by workers around a construction site, thereby ensuring the safe movement of heavy equipment and the safety of workers.

In order to achieve the above object, the present invention provides a disaster prevention platform based on worker and heavy equipment location information, which may include: an RFID tag which is provided to a worker and transmits a worker RF signal; a heavy equipment signal unit which is provided to a heavy equipment and transmits a heavy equipment RF signal; and a heavy equipment detection device which receives the worker RF signal and the heavy equipment RF signal, and outputs a danger signal to the heavy equipment when the distance at which the entire RF signal including the worker RF signal and the heavy equipment RF signal is received is within a predetermined distance.

Here, the RFID tag is provided on a safety helmet worn by the worker, and the RFID tag can be attached in a circular shape along the inner surface of the safety helmet.

Additionally, the heavy equipment detection device includes an RFID receiver, and the RFID receiver is capable of receiving the entire RF signal.

In addition, the heavy equipment detection device may further include a notification unit that outputs a danger signal to the heavy equipment based on the entire RF signal.

In addition, when the RFID receiver receives the entire RF signal and the distance at which the entire RF signal is received is less than a predetermined distance, the notification unit can output the danger signal as an audible signal to notify the worker.

Additionally, the notification unit can provide audible notification in stages depending on the distance at which the entire RF signal is received.

In addition, when the distance of the entire received RF signal is a third distance, the notification unit can output a third sound pattern having a low tone, a constant tone, and a long cycle as the auditory signal, when the distance of the entire received RF signal is a second distance, the notification unit can output a second sound pattern having a higher tone, a louder volume, and a shorter cycle than the third sound pattern as the auditory signal, and when the distance of the entire received RF signal is a first distance, the notification unit can output a first sound pattern having a repeated high and low tone, a louder volume, and a shorter cycle than the second sound as the auditory signal.

In addition, when the RFID receiver receives the entire RF signal and the distance at which the entire RF signal is received is less than a predetermined distance, the notification unit can output the danger signal as a visual signal to notify the worker.

In addition, the notification unit can provide visual signals in stages that are different depending on the distance at which the entire RF signal is received.

In addition, when the distance of the entire received RF signal is a third distance, the notification unit can output a third light source pattern having a weak light intensity and emitting light constantly as the visual signal, when the distance of the entire received RF signal is a second distance, the notification unit can output a second light source pattern having a stronger light intensity and a longer light flashing cycle than the third light source pattern as the visual signal, and when the distance of the entire received RF signal is a first distance, the notification unit can output a first light source pattern having a stronger light intensity and a shorter light flashing cycle than the second light source pattern as the visual signal.

In the present invention, a disaster prevention platform based on worker and heavy equipment location information is provided by installing an RFID tag on a heavy equipment signal unit or card carried by a heavy equipment worker, and attaching a receiver that detects an RFID tag to a worker's safety helmet at a construction site, thereby preventing collisions between heavy equipment and workers around a construction site in advance. Accordingly, the safety of the heavy equipment worker is guaranteed.

In addition, it has the effect of improving work efficiency and reliability by relieving workers' anxiety about risk factors and allowing them to perform their work in a safer work environment.

Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings. However, some components that are irrelevant to the gist of the invention will be omitted or compressed. However, the omitted components do not necessarily mean that they are not necessary for the present invention, and can be combined and used by a person having ordinary knowledge in the technical field to which the present invention belongs.

FIG. 1 is a schematic diagram illustrating a heavy equipment detection system according to an embodiment of the present invention.

As illustrated in FIG. 1, a heavy equipment detection system at a construction site according to an embodiment of the present invention may include a safety helmet (100), a heavy equipment signal unit (200), and a heavy equipment detection device (300).

The safety helmet (100) is a device that a worker wears on his head at a construction site. The safety helmet (100) has a cross-section that is roughly semicircular, a circumference that is circular, and an interior that is hollow so that the worker can wear it on his head. In addition, the material can be made of a lightweight and impact-resistant material. Since the safety helmet (100) is a known technology, a detailed description will be omitted.

An RFID tag (110) may be provided on the inner surface of the safety helmet (100). This RFID tag (110) may be formed in a circular shape along the inner surface of the safety helmet (100). The RFID tag (110) provided on the safety helmet (100) may transmit an RF signal to the outside of the worker.

The heavy equipment signal unit (200) is a configuration implemented on one side of the heavy equipment. This heavy equipment signal unit (200), like the safety helmet (100), is equipped with an RFID tag (210) inside and can transmit a heavy equipment RF signal to the outside. At this time, the RF signal transmitted by the heavy equipment signal unit (200) may include the heavy equipment type of the heavy equipment carrying the heavy equipment signal unit (200). For example, the heavy equipment type may be a type that classifies a forklift, a forklift, etc.

The heavy equipment detection device (300) is configured to receive a heavy equipment RF signal and a worker RF signal transmitted from an RFID tag (110, 210) and notify the presence of heavy equipment. This heavy equipment detection device (300) can notify a worker that there is heavy equipment around a construction site and can notify a heavy equipment operator that workers working at the construction site are at a predetermined distance. At this time, the heavy equipment detection device (300) can output different signals depending on the type of heavy equipment. Here, the heavy equipment detection devices (300) can be installed in multiple places at high or low locations around the construction site. Here, the entire RF signal including the heavy equipment RF signal and the worker RF signal is referred to as an RF signal. Therefore, unless otherwise specified, the RF signal can be regarded as the entire RF signal including the heavy equipment RF signal and the worker RF signal.

FIG. 2 is a drawing exemplarily showing an RFID tag (110) equipped on a safety helmet (100) in a heavy equipment detection system according to an embodiment of the present invention.

As shown in Fig. 2, in the heavy equipment detection system according to the embodiment of the present invention, an RFID tag (110) is provided on a safety helmet (100). This RFID tag (110) may be provided on the inner surface of the safety helmet (100). In this case, the RFID tag (110) may be provided in a circular shape along the inner surface of the safety helmet (100).

That is, the safety helmet (100) is generally formed with a cross section that is approximately semicircular, the circumference is formed in a circular shape, and the interior is hollow in order to be placed on the worker's head. An RFID tag (110) can be attached to the inner surface of the safety helmet (100) in the form of a circular band. The RFID tag (110) can transmit an RF signal to the outside in real time or periodically. Here, since the RFID tag (110) is a known technology, a detailed description will be omitted.

FIG. 3 is a block diagram showing the configuration of a heavy equipment detection device (300) in a heavy equipment detection system according to an embodiment of the present invention.

As illustrated in FIG. 3, a heavy equipment detection device (300) according to an embodiment of the present invention may include an RFID receiving unit (310), a control unit (320), and a notification unit (330).

The RFID receiver (310) is configured to receive an RF signal transmitted from an RFID tag (110) equipped on a safety helmet (100). This RFID receiver (310) may be included inside a heavy equipment signal unit (200).

The control unit (320) is configured to control the notification unit (330) based on the received RF signal. The control unit (320) can determine the distance to the RFID tag based on the received RF signal, and control the notification unit (330) to operate differently depending on the distance of the received RF signal. In addition, the control unit (320) can determine the type of heavy equipment based on the received RF signal, and control the notification unit (330) to perform different notifications accordingly.

The notification unit (330) is configured to perform different notifications to the heavy equipment according to the distance of the received RF signal under the control of the control unit (320). This notification unit (330) may be provided on the outside of the heavy equipment detection device (300). Here, the notification unit (330) may include a visual notification means (331) and an auditory notification means (332). Accordingly, the notification unit (330) may perform an auditory notification to the worker using the auditory notification means (332) and a visual notification using the visual notification means (331).

FIG. 4 is a drawing exemplarily showing a heavy equipment detection device (300) receiving an RF signal transmitted by an RFID tag (110) equipped on a safety helmet (100) and an RFID tag (210) equipped on a heavy equipment signal unit (200) in a heavy equipment detection system according to an embodiment of the present invention.

As illustrated in FIG. 4, the heavy equipment detection system according to an embodiment of the present invention can notify workers of danger around a construction site by having the RFID receiving unit (310) equipped in the heavy equipment signal unit (200) receive an RF signal transmitted from an RFID tag (110) equipped in a safety helmet (100) and the notification unit (330) output a danger signal.

Specifically, at a construction site, there may be a large number of workers working. At this time, when heavy equipment is moving around the construction site, workers may be at risk due to vehicles passing by the construction site or heavy equipment.

A safety helmet (100) worn by workers at a construction site may be equipped with an RFID tag (110) in a circular shape on the inside, and an RF signal may be transmitted from the RFID tag (110) in real time or periodically.

In addition, heavy equipment moving around a construction site has a heavy equipment signal unit (200) implemented on one side, and an RF signal can be transmitted in real time or periodically from an RFID tag (210) equipped in the heavy equipment signal unit (200).

Therefore, the RFID receiver (310) can receive an RF signal transmitted from an RFID tag (110, 210).

At this time, the control unit (320) can control the notification unit (330) to output a visual signal or an auditory signal as an auditory notification means (332) or a visual notification means (331) depending on the type of heavy equipment to notify the worker of the danger.

In this way, the control unit (320) controls the notification unit (330) to perform a notification using an auditory notification means (332) or a visual notification means (331) depending on the type of heavy equipment, which can be performed based on the type of heavy equipment included in the signal transmitted by the RFID tag (210) of the heavy equipment signal unit (200). That is, the type of failure of the heavy equipment carrying the heavy equipment signal unit (200) can be registered in advance in the heavy equipment signal unit (200).

Due to this, workers at construction sites can easily detect and avoid heavy equipment, and heavy equipment around construction sites can also easily detect and avoid danger.

FIG. 5 is a drawing exemplarily showing that, in a heavy equipment detection system according to an embodiment of the present invention, a heavy equipment detection device (300) receives an RF signal transmitted from an RFID tag (110) equipped on a safety helmet (100) and an RFID tag (210) equipped on a heavy equipment signal unit (200), and performs an audible notification to a worker differently depending on the distance.

As illustrated in FIG. 5, the heavy equipment detection system according to the embodiment of the present invention can receive an RF signal transmitted from an RFID tag (110) equipped on a safety helmet (100) and an RF signal transmitted from an RFID tag equipped on a heavy equipment signal unit (200) through an RFID receiving unit (310) and can notify a worker and a heavy equipment operator of a danger signal through a notification unit (330).

Here, the notification unit (330) can perform notification differently depending on the distance of the RF signal received by the RFID receiver unit (310). That is, including the distances of the worker RF signal and the heavy equipment RF signal received from the RFID tag (110) equipped on the safety helmet (100) and the RFID tag equipped on the heavy equipment signal unit (200), if the distance is short, it can be determined that the worker is more exposed to danger because the worker is closer to the construction site.

On the other hand, if the distance of the total received RF signal is far, including the distance of the worker RF signal and the heavy equipment RF signal received from the RFID tag (110) equipped on the safety helmet (100) and the RFID tag equipped on the heavy equipment signal unit (200), it can be determined that the worker is less exposed to risk because he is relatively far from the heavy equipment at the construction site.

Accordingly, the notification unit (330) can perform different notifications according to a preset range based on the distance of the entire RF signal received by the control unit (320). These notifications can be applied differently to the auditory notification means (332).

For example, if the notification unit (330) wants to notify workers about a danger at a construction site, the notification can be performed differently using an auditory notification means (332) depending on the distance at which the RFID receiving unit (310) receives the RF signal.

Specifically, the distance at which the RF signal is received can be classified into three stages: the closest first distance, the second distance longer than the first distance, and the farthest third distance, according to the preset distance. Here, the third distance may be approximately more than 70 m and less than or equal to 100 m, the second distance may be approximately more than or equal to 40 m and less than or equal to 70 m, and the first distance may be approximately more than or equal to 0 m and less than or equal to 40 m.

Accordingly, if the control unit (320) determines that the worker at the construction site is in the vicinity of the heavy equipment when the distance of the received RF signal is the third distance, but is relatively less dangerous to the heavy equipment, the control unit (320) controls the auditory notification means (332) to output a sound pattern to warn the worker. At this time, the auditory notification means (332) can output a third sound pattern that is low, constant, and has a long cycle under the control of the control unit (320) to notify the worker of the danger.

In addition, the control unit (320) determines that when the distance of the received RF signal is the second distance, the worker at the construction site is present around the heavy equipment, but is relatively more dangerous from the heavy equipment than at the third distance, and thus controls the auditory notification means (332) to output a sound pattern to strongly alert the worker. At this time, the auditory notification means (332) can output a second sound pattern that is higher in pitch, louder in volume, and shorter in cycle than the third sound pattern under the control of the control unit (320) to notify the worker of the danger.

In addition, the control unit (320) controls the auditory notification means (332) to output a sound pattern to notify that workers at a construction site are very dangerously close to heavy equipment when the distance of the received RF signal is the first distance. At this time, the auditory notification means (332) can output a first sound pattern that has a higher and lower pitch, a louder volume, and a shorter cycle than the second sound pattern, under the control of the control unit (320), to notify the worker that there is a construction site nearby.

FIG. 6 is a drawing exemplarily showing that, in a heavy equipment detection system according to an embodiment of the present invention, a heavy equipment detection device (300) receives an RF signal transmitted from an RFID tag (110) equipped on a safety helmet (100) and an RFID tag (210) equipped on a heavy equipment signal unit (200), and visually notifies a worker differently according to the distance.

As illustrated in FIG. 6, the heavy equipment detection system according to the embodiment of the present invention can receive an RF signal transmitted from an RFID tag (110) equipped on a safety helmet (100) and an RF signal transmitted from an RFID tag equipped on a heavy equipment signal unit (200) through an RFID receiving unit (310) and can notify a worker of a danger signal through a notification unit (330).

Here, the notification unit (330) can perform notification differently depending on the distance of the RF signal received by the RFID receiver unit (310). That is, if the distance of the total received RF signal, including the distance of the worker RF signal and the heavy equipment RF signal received from the RFID tag (110) equipped on the safety helmet (100) and the RFID tag equipped on the heavy equipment signal unit (200), is short, it can be determined that the worker is more exposed to danger because the worker is closer to the construction site.

On the other hand, when the distance of the received RF signal is far, including the distance of each RF signal received from the RFID tag (110) equipped on the safety helmet (100) and the RFID tag equipped on the heavy equipment signal unit (200), it can be determined that the worker is less exposed to risk because the worker is relatively far away from the construction site.

Accordingly, the notification unit (330) can perform different notifications according to a preset range based on the distance of the received RF signal by the control unit (320). These notifications can be applied differently to the visual notification means (331).

For example, if the notification unit (330) wants to notify the worker about a danger at a construction site, the notification can be performed differently using a visual notification means (331) depending on the distance at which the RFID receiving unit (310) receives the RF signal.

Specifically, the distance at which the RF signal is received can be classified into three stages: the closest first distance, the second distance longer than the first distance, and the farthest third distance, as described above, based on the preset distance.

Accordingly, if the control unit (320) determines that a worker at a construction site is present around the heavy equipment when the distance of the received RF signal is the third distance, but that it is relatively less dangerous to the worker, the control unit (320) controls the visual notification means (331) to output a light source pattern to warn the worker. At this time, the visual notification means (331) can output a third light source pattern that has a weak light intensity and emits light consistently under the control of the control unit (320) to inform the worker that there is a construction site nearby.

In addition, the control unit (320) determines that when the distance of the received RF signal is the second distance, although a worker at the construction site is present around the worker, it is relatively more dangerous to the worker than the third distance, and thus controls the visual notification means (331) to output a light source pattern so as to strongly alert the worker. At this time, the visual notification means (331) outputs a second light source pattern with stronger light intensity and a longer light blinking cycle than the third light source pattern under the control of the control unit (320), so as to inform the worker that there is a construction site nearby and that there is danger.

In addition, the control unit (320) controls the auditory notification means (332) to output a light source pattern to notify that a worker at a construction site is very dangerous due to the worker's presence near the worker when the distance of the received RF signal is the first distance. At this time, the visual notification means (331) can output a first light source pattern with a stronger light intensity and a shorter light blinking cycle compared to the second light source pattern under the control of the control unit (320) to notify the worker of the danger.

Additionally, the present invention can transmit signals differently to workers depending on the type of heavy equipment.

The above preferred embodiments of the present invention have been disclosed for the purpose of illustration, and those skilled in the art with common knowledge of the present invention will be able to make various modifications, changes, and additions within the spirit and scope of the present invention, and such modifications, changes, and additions should be considered to fall within the scope of the claims of the present invention.
