Workers at industrial sites, construction sites and many other workplaces should wear safety helmets. Hard hat is equipment to protect worker's head in case of crisis such as falling of dangerous goods or falling of worker at work site.

In general, the hard hat is a head band fixed to surround the operator's head inside the hard outer housing and the outer housing, a cushioning material disposed inside the outer housing to absorb the shock applied from the outside of the outer housing so as not to be transmitted to the operator's head and It is configured to include a wear strap that is connected to the outer housing or the head band and tightened over the lower part of the operator to prevent the helmet from being randomly released from the operator.

Safety helmet of such a configuration must be worn by the operator when tightening the strap securely, but can protect the head of the worker in case of accident. However, in the actual workplace, the worker does not hang on the lower part of the wearing strap due to discomfort or a mistake in wearing, or even when the lower part does not securely tighten.

Recently, as safety awareness is improved, most workers wear hard hats so that the wearing straps are spread over the lower part of the pipe. However, the problem of wearing loose without being properly tightened is still occurring.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In addition, in order to clearly describe the present invention, parts irrelevant to the description are omitted, and the same reference numerals in the drawings indicate the same members.

In addition, the terms "... unit", "... unit", "module", "block", etc. described in the specification mean a unit for processing at least one function or operation, which means hardware, software, or hardware. And software.

1 and 2 are a perspective view and an exploded perspective view of a helmet having a wear detection device according to an embodiment of the present invention, Figure 3 is a view showing the appearance of the wear detection device of Figure 1, Figure 4 is a Shows a schematic configuration of the wear detection device.

1 and 2, the hard hat 10 according to the present embodiment includes an outer housing 110, a head band 120, a cushioning material 130, a wearing strap 140, and a wearing detection device 150. It is configured by.

The outer housing 110 is generally made of a hard plastic or synthetic resin material, and absorbs the impact from the outside at the work site so that it is not directly applied to the worker.

Head band 120 is coupled to the inner side of the outer housing 110 is formed to surround the head of the worker so that the worker can wear a hard hat. At this time, the head band 120 is coupled to be spaced apart from the inner surface of the outer housing 110, to prevent the shock applied to the outer housing 110 is transmitted directly to the head of the worker.

The shock absorber 130 is disposed inside the outer housing 110 together with the head band 120 so that an impact applied from the outside of the outer housing 110 is not transmitted to the head of the worker. As illustrated in FIG. 2, the shock absorber 130 may be implemented as a band in which the shock absorber 130 is coupled to the head band 120 and the outer housing 110 is disposed to be spaced apart from the inside, for example. The absorbent material may be formed to be attached to the inside of the outer housing 110. In addition, even when implemented in a band form, an additional shock absorbing material may be further disposed between the band and the inner side of the outer housing 110.

Meanwhile, the wearing strap 140 is generally coupled to the head band 120 to fix the hard hat 10 together with the head band 120 to the head of the worker. While the head band 120 wraps around the forehead of the worker, the wearing strap 140 is stretched to cover the lower duct including the chin of the worker so that the helmet 10 does not escape from the head of the worker even when the worker's posture changes. .

The wear detection apparatus 200 is coupled to the wear strap 140 to detect whether the chin of the operator and the lower side of the chin close contact, to determine whether the wear strap 140 is tightened stably. That is, the worker senses whether the helmet 10 is normally worn. Here, the wear detection device 200 detects whether the wearer 140 is in close contact with not only the jaw of the worker, but also when the wear strap 140 is in close contact with the worker's jaw, when the wear strap 140 is loosely tightened. Because.

The jaw can be easily adhered to the wearing strap 140 even if the wearing strap 140 is not securely tightened by a part protruding from the operator's face. Therefore, when only detecting whether it is in close contact with the jaw, it can be determined whether the wearing strap 140 is used, but it cannot be determined whether the wearing strap 140 is tightened stably.

When the wearing strap 140 is not normally tightened when the hard hat 10 is worn, the hard hat may be separated from the head of the worker according to the posture or state of the worker. That is, there is a possibility that a problem occurs in the safety of the worker. Therefore, the wear detection apparatus 200 according to the present embodiment senses whether the lower side of the close contact with the chin as well, by tightly tightening the wearing strap 140 to determine whether or not wearing the helmet 10 normally.

The wear detection device 200 is a first detection unit 210 for detecting the close contact of the jaw and the second detection unit 220 for detecting the lower side in order to detect the close contact with the lower tube as well as the jaw. It includes a connection unit 230 for electrically connecting the first sensing unit 210 and the second sensing unit 220. That is, the first and second sensing units 210 and 220 are divided into configurations for sensing the jaw and the lower side of the tube, and the divided first and second sensing units 210 and 220 may be bent according to the shape of the face. By being connected through the connection unit 230 to minimize the inconvenience of the operator at the same time to be able to determine whether the contact more accurately.

Here, the wear detection apparatus 200 may be implemented as a separate configuration from the wear strap 140 as shown in FIG. 2, and may be coupled to or separated from the wear strap 140. To this end, at least one of the first sensing unit 210 and the second sensing unit 220 of the wear detection apparatus 200 may further include a fastening means (not shown) for coupling with the wearing strap 140. . However, the wear detection apparatus 200 may be integrally formed so as not to be separated from the wear strap 140. In addition, the distance between the first sensing unit 210 and the second sensing unit 220, that is, the length of the connection unit 230 may be variously adjusted.

Referring to FIG. 4, each configuration of the wear detection apparatus 200 will be described in detail. The first and second detection units 210 and 220 may be worn sensor units for detecting close contact between the operator's jaw and the lower side of the pipe, respectively. (211, 221). The wear sensor 211 and 221 may be implemented as a proximity sensor (or a touch sensor) as a sensor for detecting human contact, and may be implemented as a capacitive proximity sensor. Proximity sensors of the capacitance correction method can detect proximity to the human body through the change in capacitance, it is possible to detect the close contact between the jaw and the lower side even without direct contact with the human body.

In the present exemplary embodiment, the wear sensor units 211 and 221 may be implemented as a contact sensor that detects whether the human body is in direct contact, not a proximity sensor that detects the proximity of the human body. However, the wear detection device 200 during operation may be exposed to various surrounding environments, particularly outdoor environments affected by weather such as rain or snow, by using a hard hat that may be used in various working environments. It can also be exposed to worker sweat.

Therefore, when the wear sensor unit 211, 221 is implemented as a contact sensor that requires direct exposure to the outside of the wear detection device 200, moisture may be introduced into the inside to greatly reduce the durability of the wear detection device 200. In addition, the detection deviation may be large. Accordingly, the wear detection apparatus 200 according to the present exemplary embodiment seals a substrate in which at least one sensor including the wear sensor units 211 and 221 is disposed in the first and second sensing units 210 and 220, respectively, in the outer case. It is formed integrally, and by implementing the wear sensor 211, 221 as a proximity sensor, it is possible to improve the durability of the wear detection device 200.

For example, the first and second detection units 210 and 220 may arrange a component including at least one sensor on a substrate, insert the substrate on which the component is disposed, into a mold prepared in advance in a shape corresponding to a case, By pouring a liquid resin or the like into the mold and hardening it, an outer case in which the inside is sealed can be formed. The resin case manufactured in this manner has an advantage of excellent sealing effect and low manufacturing cost.

Meanwhile, at least one of the first and second detectors 210 and 220 may include a power supply unit 228 for supplying power to the wear sensor units 211 and 221 and the first and second detectors 210 and 220. The controller 223 may further include a control unit 223 configured to receive the first and second detection signals to determine whether the first and second detection signals are in close contact. In this case, the first and second sensing units 210 and 220 respectively include the power supply unit 228 and the control unit 223, which is inefficient for the wear detection apparatus 200 that must be manufactured at a small cost. Therefore, in the present embodiment, for example, the first sensing unit 210 includes only the first wearing sensor unit 211, and the second sensing unit 220 includes the power supply unit 228 and the second wearing sensor unit 221. It is assumed that an additional configuration such as the control unit 223 is further included. Here, the additional configuration is further included in the second sensing unit 220 instead of the first sensing unit 210, compared to the first sensing unit 210 which is in close contact with the jaw. This is because even if a relatively wide size is implemented, it can reduce the inconvenience to the worker. However, the present invention is not limited thereto.

When the controller 223 is disposed in the second detector 220, the controller 223 receives the first detection signal from the first detector 210 through the connection unit 300, and the second detector 220. The second detection signal is applied to determine whether the worker wears the helmet 10 normally. At this time, the control unit 223 is the first and second detection signals from the first and second detection unit 210, 220 is determined that the operator is in close contact with both the jaw and the lower side of the operator, respectively, the worker wearing the helmet 10 It can be determined that it is worn normally.

The second sensing unit 220 may include additional components in addition to the second wearing sensor unit 221, the control unit 223, and the power supply unit 228. Referring to FIG. 4, the second sensing unit 220 may further include an acceleration sensor unit 222, a location information acquisition unit 224, an alarm unit 225, a communication unit 226, and an additional sensor unit 227. Can be.

The acceleration sensor unit 222 detects an acceleration due to the movement of the wear detecting device 200 and transmits an acceleration signal to the control unit 223. The acceleration sensor unit 222 is provided to detect whether a safety accident, such as a fall of the operator. When the controller 223 determines that the worker wears a hard hat, the controller 223 analyzes the acceleration signal transmitted from the acceleration sensor unit 222 to determine whether a safety accident has occurred to the worker, and when it is determined that the safety accident has occurred. The emergency signal may be transmitted to a work management server (not shown) through a portable terminal of an interworking worker.

The location information acquisition unit 224 acquires the location information of the helmet 10 and transmits the location information to the control unit 223. Here, the helmet 10 confirms the location information including the location information acquisition unit 224 to determine whether the worker is located in a place where the helmet 10 should be worn, and promptly in case of a safety accident of the worker. This is to be able to respond.

The alarm unit 225 generates a warning to the worker under the control of the controller 223. The controller 223 analyzes the first and second detection signals applied from the first and second wearing sensor units 211 and 221 to determine whether the worker wears a hard hat normally, and if it is determined that the user wears the helmet abnormally, an alarm is detected. The control unit 225 generates a warning to the worker.

The communication unit 226 allows the wear detection apparatus 200 to communicate with at least one predetermined external device. In the present embodiment, the communication unit 226 allows the wear detection apparatus 200 to communicate with a portable device of an operator, for example, and may use various wireless communication methods such as Bluetooth, WIFI, and the like. When the wear detection apparatus 200 is configured to communicate with a worker's portable device, since the function of the portable device may be used, the location information acquisition unit 224 and the alarm unit 225 may be omitted.

The additional sensor unit 227 includes various sensors for performing additional functions not directly related to the function of the helmet 10. Workers on site can be located at many different job sites. Therefore, when a variety of additional sensors are provided in the helmet 10 worn by the operator, it is possible to accurately obtain accurate information about each detailed area.

For example, measurement of local environmental information such as fine dust level, humidity, temperature, etc. is currently performed using sensors disposed at predetermined positions. However, sensors that measure the environment in each area are placed at very long distances. Therefore, there is a limit in that accurate environmental information cannot be obtained for each detailed region. On the other hand, the worker wearing the hard hat 10 is to perform the work in a variety of work sites, some workers may perform the work while moving several locations within the designated area range. In addition, in the present embodiment, since the wear detection apparatus 200 may include a location information acquisition unit 224 or communicate with a worker's portable device (not shown) through the communication unit 226, the safety helmet 10 ) Can pinpoint the current position of the.

Therefore, when various additional sensors are included in the wear detection apparatus 200, various pieces of information in each detailed area may be collected. The detailed regional information collected in this way is transmitted to a separate information collection server (not shown) through a portable device, and may be provided as basic data for providing weather information or the like, or may be used later for big data.

Meanwhile, the first and second detectors 210 and 220 are divided, and only the second detector 220 of the first and second detectors 210 and 220 includes a power supply unit 228 and a controller 223. According to the configuration, the wear detection device 200 supplies power to the first detection unit 210 and transmits the first detection signal detected by the first detection unit 210 to the second detection unit 220. It includes a connector 230.

When the first and second detectors 210 and 220 are not connected to the flexible cable 231 and are integrally fixed, the wear detection apparatus 200 may be in close contact with the shape of various workers. Can not. In this embodiment, the first and second sensing units 210 and 220 are connected by using the connection unit 230 formed of the flexible cable 231 so as to be in close contact with the shape of the face of various workers. The connection unit 230 may be implemented as, for example, flexible printed circuits (FPCs) or flexible flat cables (FFCs).

In addition, the connection unit 230 may further include a memory wire 232. The memory wire 232 is formed of a shape memory alloy and has a restoring force to be restored to its original shape even when the shape is deformed by an external force. The memory wire 232 allows the first sensing unit 210 and the second sensing unit 220 to be fixed at a predetermined distance and angle as much as possible. When the first sensing unit 210 and the second sensing unit 220 are connected only by the soft cable 231, the second sensing unit 220 must be tightened very strongly according to the shape of the operator's face. It may be in close contact with the lower tube side. However, tightening the wearing strap 140 will cause inconvenience to the worker to wear a hard hat for a long time. In addition, since the flexible cable 231 is vulnerable to tensile force, the flexible cable 231 may be broken by tightening the wearing strap 140.

The connection unit 230 further includes a memory wire 232 so that the first detection unit 210 and the second detection unit 220 can maintain a fixed distance and angle to the various face shapes of the operator. At the same time reduce the inconvenience, even if the tensile force is applied so that the flexible cable 231 is not broken.

FIG. 5 illustrates a schematic configuration of a work management system using the hard hat wearing detection device of FIG. 1.

Referring to FIG. 5, the work management system may include a hard hat 10, a portable device 20 linked with the hard hat 10, and a work management server 30.

In FIG. 5, as shown in FIGS. 1 and 2, the helmet 10 communicates with the worker's portable device 20, including the wear detection device 200, to display the worker's helmet wearing information. 20). In addition, if it is determined that a safety accident has occurred to the user based on the acceleration signal detected by the acceleration sensor unit 222 of the wear detection apparatus 200, the emergency signal is transmitted to the portable device 20. In addition, the additional information is acquired and transmitted to the portable device 20 according to the additional sensing signal sensed by the at least one sensor of the additional sensor unit 227.

The portable device 20 obtains work position information from which the worker should perform a work from the work management server 30, and if it is determined that the worker has arrived at a position corresponding to the work position information, activates the wear detection apparatus 200. The wear detection apparatus 200 may detect whether the worker wears a hard hat. In some cases, the portable device 20 may determine whether the wear detection apparatus 200 is activated using various other means in addition to the location information. For example, the portable device 20 may activate the wear detection device 200 when the worker executes an app installed on the portable device 20 and configured to work with the wear detection device 200.

When the wearing information of the helmet is transmitted from the wear detecting apparatus 200, the wearing helmet information is transmitted to the work management server 30 together with the position information of the worker. In addition, even when an emergency signal or additional information is transmitted, the emergency management signal and additional information may be transmitted to the work management server 30 together with the location information. In this case, when the location information is not included in the wear detection device 200 of the hard hat 10 because the location information is not applied, the portable device 20 directly obtains the location information and manages the work management server 30. Can be delivered to. And when the alarm unit 225 is not included in the wear detection device 200, it may output a warning to the operator in accordance with the wearing helmet information.

The job management server 30 may transmit job location information to the worker's portable device 20, and receive and store helmet wearing information from the portable device 20. In some cases, the job management server 30 may transmit or output the helmet wearing information to the job manager. When the emergency signal is transmitted, the task management server 30 may transmit the corresponding information to a predetermined medical server, so that the medical institution may respond to the emergency situation for the worker.

On the other hand, the job management system according to the present embodiment may further include an additional information collection server 40. When the additional information collection server 40 is included, the job management server 30 transmits additional information transmitted from the wear detection apparatus 200 through the portable device 20 to the additional information collection server 40, thereby adding the additional information. The information collection server 40 may allow the collected additional information to be stored.

However, in some cases, the portable device 20 may be configured to deliver additional information directly to the additional information collecting server 40. Similarly, when the emergency signal is received from the wear detection apparatus 200, the portable device 20 may directly transmit the emergency signal together with the location information to the medical server.

Figure 6 shows a method of operating a safety helmet wearing detection device according to an embodiment of the present invention.

1 to 5, the operating method of the hard hat wearing detection device according to the present embodiment will be described. First, the wearing detection device 200 coupled to the wearing strap 140 of the hard hat 10 is activated (S11). ). The wear detection apparatus 200 may activate various methods. For example, the wear detection device 200 may be activated by the portable device 20 of a worker who communicates, and the portable device 20 may be configured to execute an app configured to work with the wear detection device 200, or may be located at a current location. May be activated when the location corresponding to the job location information transmitted from the job management server 30 is determined.

The activated wear detection device 200 detects whether the worker's jaw and lower side of the tube is in close contact and obtains first and second detection signals (S12). In this case, the wear detection apparatus 200 may also acquire location information when the location information acquisition unit 224 is included.

When the first and second detection signals are acquired, the wear detection apparatus 200 determines whether the hard hat 10 is in a normal wearing state by analyzing the first and second detection signals (S13). At this time, the wear detection apparatus 200 determines that the worker is in a normal wearing state in which the worker wears the helmet 10 normally only when it is determined that both the jaw and the lower side of the pipe are in close contact.

As a result of the determination, when it is determined that the hard hat 10 is not in a normal wearing state, the wearing detection device 200 outputs a warning to the worker using the built-in alarm unit 225 or the portable device 20 for communicating. (S14). The first and second sensing signals are obtained again.

Meanwhile, when it is determined that the hard hat 10 is in a normal wearing state, the wearing detection device 200 analyzes an acceleration signal obtained through the acceleration sensor unit 222 to determine whether the hard hat 10 has a predetermined reference acceleration or more. Determine (S15). If it is determined that the acceleration is greater than or equal to the reference acceleration, the wear detection apparatus 200 determines that a safety accident such as a fall has occurred to the worker, generates an emergency signal, and transmits the emergency signal to the portable device 20 (S16). The portable device 20 transmits the location information along with the emergency signal to the job management server 30 or the emergency server, so that the worker can receive the emergency rescue.

Meanwhile, the wear detection apparatus 200 obtains an additional sensing signal through at least one additional sensor of the additional sensor unit 227, generates additional sensing information from the obtained additional sensing signal, and transmits the additional sensing information to the portable device 20. . The portable device 20 transmits the location information together with the additional sensing information to the additional information collecting server 40, so that the additional information collecting server 40 collects and collects additional information for each detailed location, and the basic data of the big data in the future. To be used.
