The multifunctional helmet according to the embodiment of the present invention includes a body 110, a CDS sensor 151, a gas detection sensor 152, a heart rate monitor 153, a distance detection sensor 154, 155, and a controller 170 for controlling the head lamp 120, the buzzer 130, the character matrix 140, the sunglasses 180 and the camera 190, and the sensors 170, And a communication interface 160 for transmitting the information obtained from the external device to the outside.

The multifunctional helmet according to the embodiment of the present invention combines these components to identify various risk factors at the worksite and issue a warning to cope with the worker as well as other workers working around the worker.

Hereinafter, each of the above components will be mainly described.

The mother body 110 has a hemispherical shape and has an inner space opened downwardly to receive an operator's head, and is not so different from other helmets.

The CDS sensor 151 is installed on a part of the outer surface of the mother body 110 to sense ambient illuminance. The CDS sensor 151 is an illuminance sensor having a property of reducing the resistance when the surroundings are bright and increasing the resistance when the surroundings are darkened. The main material is the cadmium sulfide (CdS) which is a compound of cadmium (Cd) and sulfur (S). When the CDS sensor 151 detects light below a predetermined illuminance, the head lamp 120 is turned on under the control of the controller 170. Here, when the CDS sensor 151 detects light below a predetermined illuminance, the head lamp 120 emits white light. Meanwhile, the CDS sensor 151 cooperates with the thermal sensor 155 in a condition different from a condition for irradiating the head lamp 120 to lower the sunglasses 180 during welding. The sunglasses 180 will be described in detail. The CDS sensor 151 may be additionally provided to a suspenders that pass through the right breast among the suspenders worn by an operator.

The gas sensing sensor 152 is installed on the outer surface of the matrix 110 to sense a specific concentration of gas. The gas sensing sensor 152 can be divided into a system using silicon oxide and a semiconductor type gas sensor. In the sensor used in the embodiment of the present invention, when the power is applied in the silicon oxide method, the sensor temperature rapidly increases, and the resistance of the semiconductor sensor sharply decreases. As the temperature rises, the oxygen gas is adsorbed, and the free electrons in the conduction band are trapped by the oxygen gas, thereby increasing the resistance of the sensor. This allows us to measure the concentration of oxygen or other gases. However, since the ion desorption process takes a long time, an initial delay circuit of 1 to 5 minutes is required, and a preheating time is required. Because it measures based on the difference of voltage by the resistance value, it is appropriate to receive DATA value using AnalogPin in Arduino.

In the embodiment of the present invention, the type of gas detected by the gas detection sensor 152 is mainly concerned with lethal carbon monoxide. When the gas sensing sensor 152 is installed, if the concentration of the specific gas detected by the gas sensing sensor 152 is equal to or higher than a predetermined value, the controller 170 recognizes it as a dangerous situation, The color of the light is converted into a red color so as to generate a warning signal, and the buzzer 130 generates a warning sound. Further, the dot matrix 140 is used to display the SOS signal. Information about the gas leakage is provided to the integrated management department installed in the central control room through the controller to designate the dangerous area. Thereafter, the people located in the dangerous area are irradiated with the red light from the head lamp 120.

As shown in FIG. 1, the heart rate monitor 153 is mounted on a suspender which passes through a left breast of a suspenders worn by an operator, and measures the heart rate of an operator. When the heart rate measured by the heart rate meter 153 is less than a predetermined value, the controller 170 issues a warning sound through the buzzer 130 and sequentially displays S, O and S characters through the character matrix 140 . If the heart rate is zero, the worker is considered to be dead and displays a different character indicating death of the worker. For example, D, E, A, and D characters indicating death are sequentially displayed. And blinking the character matrix 140 to alert the attention of surrounding workers.

The distance sensor 154 detects the distance to the surrounding obstacle. When the distance is less than a certain distance, the controller 170 emits a warning sound through the buzzer 130, so that the head collides with the obstacle . The distance sensor 154 may include a first distance sensor 154a installed on the front surface of the matrix 110 and emitting a sensing signal to the front of the matrix 110, A second distance detection sensor 154b installed on the left and right sides of the mother body 110 and emitting a detection signal laterally; a second distance detection sensor 154c installed on the rear surface of the mother body 110 to detect And a fourth distance detection sensor 154d for launching. Here, the distance sensor 154 may be an infrared sensor, but an ultrasonic sensor may be used.

The heat sensing sensor 155 is installed on the front surface of the matrix 110 to sense ambient heat. When the heat sensor 155 senses heat of a predetermined level or higher, the sunglass motor 181 is driven to lower the sunglass 180. As a result, Can be made in a state of wearing. Also, it is preferable that the heat sensing sensor 155 is installed on the front side of the suspenders as shown in the figure.

The head lamp 120 is mounted on the front surface of the matrix 110 as shown in FIG. 6 and includes three primary color (RGB) LEDs 123 to illuminate light in various colors. The head lamp 120 basically performs a function of illuminating the front side of the matrix 110 with white light by being illuminated under the control of the controller 170 when the CDS sensor 151 detects light below a predetermined illuminance . In addition, when the gas sensing sensor 152 senses a gas concentration of a specific type to a predetermined level or more, the controller 170 controls the three primary colors (RGB) LEDs 123 to emit red To light the worker and the surrounding worker.

Furthermore, the head lamp 120 can be detachably attached to the mother body 110 so that the operator can utilize the head lamp 120 as a flashlight. To this end, the head lamp 120 is configured such that cylindrical bodies 121a, 121b, and 121c are stretchably coupled in a multi-step fashion, and a lens 122 and a three-color LED (RGB) When the head lamp 120 is detachable, the head lamp 120 can not receive the support of the main battery 195 when the head lamp 120 is detached from the body 110. Therefore, the head lamp 120 itself is provided with a rechargeable battery And an on-off switch (not shown) is mounted inside the cylindrical body so that it is automatically turned on when the cylindrical bodies are extended.

The buzzer 130 sounds a warning sound under the control of the controller 170 when the distance from the obstacle detected by the distance sensor 154 is less than a certain distance. In addition, under the control of the controller 170, the gas sensor 152 generates a warning sound in a dangerous situation such as when the gas sensor 152 detects a gas having a predetermined concentration or more.

The character matrix 140 may include a character string indicating a dangerous state by the controller 170 when the concentration of a specific type of gas detected by the gas detection sensor 152 is greater than a predetermined value, Display. Especially in a dangerous situation, as shown in FIG. 5, the characters S, O, and S are sequentially displayed, and the attention is turned around by flickering. As described above, if the heart rate measured by the heart rate meter 153 is less than a predetermined value, the buzzer 130 generates a beep sound and sequentially displays the S, O, and S characters through the character matrix 140 . When the heart rate value is 0, it distinguishes it and displays a character indicating death of the worker.

The sunglasses 180 are connected to the shaft 182 of the sunglass motor 181 so that they can be lifted and lowered from the front surface of the mother body 110. Here, the sunglasses motor 181 is installed on the left and right sides of the mother body 110. When the sunglasses 180 are lifted from the front surface of the mother body 110 while being rotated by the sunglass motor 181 as described above, the heat sensor 155 detects the heat of a predetermined level or higher, The sunglasses 180 is lowered to be worn by the operator in order to protect the visual acuity of the worker.

The camera 190 is installed on the front surface of the mother body 110 and can transmit the photographed image to the outside through the communication interface 160. When the photographing camera 190 is installed as described above, an image photographed through the communication interface 160 is transmitted to an external central control center for image monitoring.

The communication interface 160 may include a CDS sensor 151, a gas sensing sensor 152, a heart rate monitor 153, a distance sensing sensor 154, a thermal sensing sensor 155, The information on the operation state of the head lamp 120, the buzzer 130, the character matrix 140, the sunglasses 180 and the camera 190 is transmitted and systematically monitored and managed at the external central control center In particular, when the above information is received from the multifunctional helmet worn by each worker, it is possible to classify a large area in which a plurality of workers are located by the area, that is, the situation of a plurality of workers wearing helmets The integrated management unit of the central control room receiving and monitoring in real time via the communication interface sets the whole area where a plurality of workers are located as a monitoring area, In the case of workers who are at risk in the workplace, the worker who is in a dangerous situation is classified as a hazard area, a warning area, and a safety area, This is done by differentiating the headlamps by inspecting the headlamps with differentiated colors according to the hazardous area, the warning area and the safe area through the controller of the helmets worn by each worker In addition, the integrated management unit displays the status of the entire area being monitored in real time through the monitor, and displays different colors according to the dangerous area, the warning area, and the safe area, thereby facilitating the handling in the central control room.
