Description

Technology Field

[0001] The present invention relates to a smart safety helmet system, and more specifically, to a smart safety helmet system used in hazardous work that provides wearability and safety to the worker. Background Technology

[0002] Workers in industrial settings are exposed to various risks depending on the type of work. For example, in industrial sites such as construction and shipbuilding, major risk factors include falls, collisions with fixed or moving objects, and gas contamination in confined spaces. To protect against falls and collisions among these risks, workers wear safety helmets to safeguard their heads.

[0003] Generally, a safety helmet refers to a head covering designed to protect the head from dangers caused by flying or falling objects while a worker is performing tasks, to prevent head injuries in the event of a fall during loading and unloading operations, and to prevent industrial accidents during electrical work where there is a risk of electric shock to the head.

[0004] Employers must ensure that safety helmets are worn during certain tasks where there is a risk of danger, and workers must also comply if they are instructed to wear them. Safety helmets generally consist of a helmet body, attachments (straps, headbands, straps, etc.), a shock-absorbing liner, a chin strap, etc., and those who manufacture or import safety helmets must undergo type inspection by a type inspection agency.

[0005] Recently, smart safety helmets equipped with broadcasting from a control center, information and communication at the work site, and location tracking functions are being developed for worker safety management at work sites.

[0006] Compliance regulations are in place at construction sites to mandate safety training for workers before work begins. Accordingly, supervisors or managers gather the workers, conduct safety training, and then deploy them to their respective work sites before starting operations.

[0007] However, since workers have different workplaces for each work area, it is difficult for them to easily gather in one place at the same time, and they end up gathering at different times and places to receive safety training.

[0008] Accordingly, safety training is currently conducted for each work part, or pre-programmed safety training messages are transmitted from the management center to each worker and delivered through the speaker of the safety helmet.

[0009] The existing safety helmets used at this time, which are capable of providing safety training, were configured to broadcast safety training via one-way communication, making it difficult for the control center to verify whether the worker had received or understood the safety broadcast.

[0033] This main board (10) can be placed in the occipital area corresponding to the back of the safety helmet, and the first sub-board (20) can be placed in the side walls corresponding to the sides of the safety helmet.

[0034] The main board (10) and the first sub-board (20) are powered by a battery (18) mounted on the main board (10), and peripheral devices such as a lantern (31), a camera (33), and sensors connected to the main board (10) are also powered by the main board (10) and operated.

[0035] The battery (18) is provided as a lithium-ion battery (18) equipped with a protection circuit and connected to a USB (17). A standardized cylindrical battery (18) that is easy to replace, manage, and secure in place can be used, but is not necessarily limited thereto.

[0036] USB (17) can use the C-Type which is mainly used in recent smart devices, but is not limited to this and can be changed appropriately according to the environment of use.

[0037] Among the multiple communication units (13, 14), the Bluetooth communication chip (13) responsible for Bluetooth communication is configured to perform short-range communication within a working radius of about 20m, and provides wireless communication that can link the smart safety helmet with a smart device, such as a smartphone carried by the wearer. This Bluetooth communication chip (13) can be replaced with another communication chip having a similar bandwidth and communication distance, and is not necessarily limited to a communication chip that uses the Bluetooth communication protocol.

[0038] In this embodiment, digitally processed voice or image information from the control unit (11) is transmitted to a terminal (60), such as a smartphone, using a Bluetooth communication chip (13) and an antenna, and can be transmitted to a remote location such as a control center (95) through the terminal (60), and conversely, voice information transmitted from a remote location through the smartphone can be received through the Bluetooth communication chip (13).

[0039] Additionally, the digital wireless communication chip (DMR, 14) is configured to transmit digitally processed voice information of the wearer, mainly from the control unit (11), to wearers wearing a smart safety helmet with a DMR function in the same frequency band, and conversely, to receive and process the information from the control unit (11) and transmit it to the wearer, thereby providing a radio function that can be used as a self-contained wide-area radio within the work area of ​​the smart safety helmet equipped with the smart safety helmet system.

[0040] The first sub-board (20) is equipped with a microphone (21) and connected to a plurality of speakers (26, 27), and is responsible for the main input / output functions related to the wearer's voice. At this time, the plurality of speakers (26, 27) may include earphones worn on the wearer's ears.

[0041] The control unit (11) is configured to output external information received by any one of the multiple communication units (13, 14) through one or more of the multiple speakers (26, 27) provided in the outer shell, receive the wearer's voice and transmit it through any one of the multiple communication units (13, 14), and can be configured to output an individual call through one of the multiple speakers (26, 27) and output a group call through another.

[0042] The control unit (11) is connected to a terminal (60) equipped with a safety management app that collects unique information of the wearer from an identification code provided on the outer shell via a Bluetooth communication chip (13), which is one of a plurality of communication units (13, 14), and can store wearer information that is synchronized with the unique information and personal information that can identify the wearer in the storage unit (15) by communicating with the terminal (60).

[0043] The control unit (11) receives external information including one or more work instructions and safety education messages from a control server through one of a plurality of communication units (13, 14) in response to the ON of either the first or second microphone button (22, 24) of the safety helmet, and outputs it to the wearer through one or more of a plurality of speakers, and can transmit one or more reply authentication information corresponding to one or more ONs of the other first or second microphone button (22, 24) of the safety helmet to the control server of the control center (95) through one of the plurality of communication units (13, 14).

[0044] The control unit (11) can perform voice wireless communication between wearers through a digital wireless communication chip (DMR, 14), which is another of the multiple communication units (13, 14).

[0045] A plurality of microphone buttons (22, 23) may include a first microphone button (22) for transmitting and receiving with the outside, and a second microphone button (24) for transmitting and receiving with the outside.

[0046] One of the first and second microphone buttons (22, 23) can be set in the control unit (11) to perform an individual call, and the other of the first and second microphone buttons (22, 23) can be set to perform a group call.

[0047] The wearer can perform a group call function by pressing the first microphone button (22) and perform an individual call function by pressing the second microphone button (24).

[0048] A plurality of microphone buttons (22, 23) are configured in the control unit (11) to individually operate a plurality of speakers (26, 27) and a microphone (21) to communicate through one of the control unit (11) and a plurality of communication units (13, 14), and when the first microphone button (22) on one side is pressed, group calls are possible, and when the second microphone button (24) on the other side is pressed, individual calls are possible.

[0049] Individual calling is a function of a wearer to make a single call with a specific wearer of the smart safety helmet or a control center (95), and group calling is a function of a call with all wearers in the work area, a specific work group, or the entire group including the control center.

[0050] Individual calls can be primarily used for the exchange of information including voice and captured images with a specific wearer through either a Bluetooth communication chip (13) or a digital wireless communication chip (DMR, 14), and group calls can be used for the exchange of information including a group of all wearers, or a specific work group or control center (95).

[0051] The control unit (11) can be configured to output external information received by any one of the multiple communication units (13, 14) of the main board (10) through any one of the multiple speakers by turning ON one of the first and second microphone (21) buttons, and when the output of the speaker is completed, to transmit reply authentication information corresponding to one or more ONs of the other one of the first and second microphone (21) buttons to the outside one or more times through any one of the multiple communication units (13, 14).

[0052] For example, a group call function is performed through the first speaker (26) linked to the first microphone button (22), and general work safety training for the whole, work safety training for specific areas, or work instructions are transmitted from the control center (95). That is, after the wearer activates the smart safety helmet app on a smartphone, receives and familiarizes themselves with the voice information through the first speaker (26) via a group call, and then presses the second microphone button (24) to transmit a reply authentication information confirming familiarity.

[0053] First and second speaker volume keys (23, 25) are provided to correspond to the first and second microphone buttons (22, 24), respectively.

[0054] These first and second speaker volume keys (23, 25) are connected to the first speaker (26) and the second speaker (27) to provide respective volume control functions.

[0055] The first sub-board (20) may be provided with an LED button (28) connected to an emergency warning LED (29) to activate the emergency warning LED (29). That is, an emergency warning LED (29) indicating danger detection may be placed on the safety helmet, and the emergency warning LED (29) is configured to be activated by the LED button (28) provided on the first sub-board (20).

[0056] In this embodiment, one or more cameras (33) connected to the main board (10) and capable of capturing one or more directions of the wearer may be mounted, and one or more other sub-boards, namely a second sub-board (30), may be further included, which are equipped with a lantern (31) and a lantern button (32).

[0057] In this embodiment, external shooting using the camera (33) or the light function using the lantern (31) and lantern button (32) is not necessarily mounted on the second sub-board (30), but if the placement area of ​​the first sub-board (20) is inevitably narrow due to the characteristics of the limited circuit placement area of ​​the safety helmet, the second sub-board (30) may be provided and configured.

[0058] The second sub-board (30) can be placed on the front of the safety helmet due to the characteristics of the light and shooting function for the wearer's front.

[0059] In this embodiment, a sensor module (40) may be further included, which is connected to the main board (10) and is provided on the outer shell to detect one or more of the wearer's surrounding environment and current state. Such sensor modules (40) may be provided in combination in the sensor bay (60), or one or more may be arranged individually.

[0060] The plurality of sensors of this sensor module (40) may include at least two of the following: a temperature and humidity sensor (41) for detecting external temperature and humidity, a proximity sensor (42) provided to detect the wearing of a safety helmet on the wearer's head, a non-contact temperature sensor (43) for detecting external temperature, an impact sensor (44) for detecting sudden movement and impact of the wearer, a GPS sensor (45), a gas detection sensor (48) for detecting harmful gases in the work environment, and a body temperature sensor (49) for detecting the wearer's body temperature. Two or more sensors may be placed in a single sensor bay (60).

[0061] The control unit (11) of the main board (10) stores information collected through the camera (33) and one or more pieces of information measured by the temperature and humidity sensor (41), proximity sensor (42), non-contact temperature sensor (43), shock sensor (44), GPS sensor (45), gas detection sensor (48), and body temperature sensor (49) in the storage unit (15) and transmits it to the outside through one or more of the communication units (13, 14), and can detect the location and condition of the wearer and environmental safety risks based on two or more pieces of information from the temperature and humidity sensor (41), proximity sensor (42), non-contact temperature sensor (43), shock sensor (44), GPS sensor (45), gas detection sensor (48), and body temperature sensor (49), and can provide warning information to one or more of other wearers and the outside.

[0062] These warning information can be output externally through automatic messages or signals using communication functions, captured video, or warning emergency warning LEDs (29).

[0063] Meanwhile, in this embodiment, the main board (10), the first sub-board (20), and the second sub-board (30) are manufactured and applied to the smart safety helmet, but this is not limited thereto. That is, the main board (10) can be implemented as a one-chip controller by a circuit design method based on a custom manufacturing method in which major functions are provided on the main board (10) without using a general-purpose microcontroller. That is, the first sub-board (10) and the second sub-board (20) can be manufactured more compactly and manufactured in the form of a single chip or a board on which the chip is mounted. Due to the characteristics of the custom circuit design, the functions of the third sub-board (30) may be added and implemented in such a chip or board.

[0064] Hereinafter, we examine a smart safety helmet to which the smart safety helmet system according to one embodiment of the present invention described above is applied. Meanwhile, it should be noted that the smart safety helmet described below merely presents an implementable embodiment to which the smart safety helmet system described above is applied, and is not limited to the following classification areas describing the circuit arrangement, and may be modified for optimal arrangement.
