The power module 190 is installed at the rear end of the helmet body 110, and includes a camera module 120, a light emitting module 130, a speaker module 140, a microphone module 150, an integrated sensing module 160, and a communication module ( 170) and the control module 180 supply operating power required for operation, and enable status notification or display through a separate LED light output.

To this end, the power module 190 includes a battery 191, a charging terminal 192, a status display unit 193, and a voltage detection unit 194, as shown in FIG.

Here, the battery 191 is made of storage of operating power, and charging of the battery 191 is made by supplying power from an external power source through the charging terminal 192.

In addition, in the status display unit 193, as shown in FIG. 1, a plurality of LEDs are sequentially installed on one side of the exterior of the helmet body 110, and whether or not light is emitted according to a signal, the type of light emitted, etc. Depending on the state change, the fact can be easily recognized by nearby workers.

Such a status display unit 193 is supplied with operating power from the battery 191 and emits light under a preset condition. The preset condition is based on the first sensing information generated through the distance sensing unit 163b according to the implementation. When there is an object that can cause a collision in front, or when a call is in progress with a target who has built a wireless communication network with the communication module 170 using the speaker module 140 and the microphone module 150, the GPS part 163a Based on the location information sensed through, it can be variously modified, such as when out of a preset work area.

Finally, the voltage detector 194 corresponds to a voltage sensor that generates operating power supply information by detecting a battery voltage and a battery voltage variation pattern generated as operating power is supplied from the battery 191 .

In connection with this, the control module 180 includes a temperature sensor 181, a microphone control unit 182, a power control unit 183, and a reset setting unit 184 to implement a specific control type.

First, the temperature sensor 181 is a temperature sensor that senses the self-heating temperature of the control module 180, and performs a soft reset when the control module 180 continues to operate and heats up severely. It is expected to provide the standard information for performing the

In this regard, the reset setting unit 184 reboots the operation of the control module 180 when the self-heating temperature of the control module 180 detected by the temperature sensor 181 exceeds a predetermined limit temperature, When the helmet 100 is used for a long time, the control module 180 prevents operation stoppage or error occurrence due to high temperature heat generation in advance.

Next, the microphone control unit 182 is a configuration for enabling transmission of a voice signal during a call only when the volume of the voice signal detected by the volume detector 152 exceeds a preset microphone activation value. .

Through this, the operator does not need to press the PTT button for performing a separate call, and the efficiency of the work can be increased by freeing the hands more.

Specifically, the microphone control unit 182 is generated by the management server 200 through the first communication unit 171 when the volume of the voice signal detected through the volume detection unit 152 exceeds a preset microphone activation value A function of relaying a channel to activate a function of making a call with the management terminal 300 or a function of making a call with another worker wearing a smart helmet 100' at an adjacent location through the second communication unit 172 will activate

Lastly, the power control unit 183 determines that the battery voltage generated as operating power is supplied from the battery 191 based on the operating power supply information generated through the voltage detection unit 194 is at the maximum level within a predetermined appropriate voltage range. If it exceeds or is detected as less than the minimum level, or if the battery voltage fluctuation pattern corresponds to a preset abnormal voltage fluctuation pattern, and abnormal symptoms such as overloading the battery or insufficient remaining power of the battery are determined, the operating power supplied from the battery 191 is saved and Battery 191 abnormal notification information is generated and transmitted to the management server 200 through the first communication unit 171 .

In connection with the smart helmet 100, the management server 200 includes a server communication unit 210, a server storage unit 220, a work area management unit 230, a call management unit 240, and a dangerous situation management unit 250. include

Next, the work area management unit 230 determines the specific work area (T) as shown in FIG. ), set at least one work cluster (T1, T2, T3) by grouping them by adjacent work positions (A1, A2, A3), and set the risk level for each work position to create work area management information. After that, it is recorded and stored in the server storage unit 220.

The work area management information generated through the work area management unit 230 in this way is a work cluster (T1, T2, T3) grouped by adjacent work locations among a plurality of work locations (A1, A2, A3) within a specific work area (T). Information indicating how this was set and information indicating how the risk level (or difficulty level) of each work position was set are reflected.

Accordingly, the work area management unit 230 determines the worker's work location based on the position information and altitude information of the worker received from the first communication unit 171 through the server communication unit 210, and then the server storage unit 220 Using the work area management information recorded and stored in the work area management information, work risk information corresponding to the worker's work position is generated and transmitted to the first communication unit 171 through the server communication unit 210.

As a result, the workers (W1, W2, W3) who are disposed at each of the plurality of work positions (A1, A2, A3) and perform the work identify the risk level of their current work position through the management server 200 and realize it. In one state, you can work more safely according to the degree of risk.

More preferably, when a certain level of risk or higher is set at a specific work position according to the difficulty of each work position (A1, A2, A3), work risk information corresponding only to workers performing work at the work position is generated and supplied. Rather than doing so, it is desirable to design the work risk information to be transmitted to workers performing work in the vicinity of the same work group (T1, T2, T3) so that they can cope with it in advance.

For example, as shown in FIG. 5 , when the work risk at the first work position A1 is at a high risk level based on the first work group T1, the first work position A1 is performed. One worker (W1) receives and checks the work risk information of the first work location (A1) from the management server 200, and at the same time, the second worker (W2) performing work at the nearby second work location (A2) ) and the third worker (W3) performing the work at the third work position (A3) is a first work position having a high risk level of work risk together with work risk information corresponding to each work position from the management server 200 High-risk work progress notification information notifying that the work of (A1) is currently being performed is also provided.

Here, the surrounding high-risk task progress notification information generated by the work area management unit 230 in the management server 200 includes information about where the first work position A1 with a high risk level of work is located in the cluster and the corresponding task It includes information about who is the first worker W1 performing the work at the location.

Next, the call management unit 240 creates a channel for conducting a call based on the voice signal, and among the created channels, a call between the smart helmet 100 and the management terminal 300 connected to the same channel can be performed. It relays and manages transmission and reception of voice signals.

To this end, the call management unit 240 uses the channel management unit 241 to form a channel capable of one-way or two-way communication after connection based on the call channel creation request signal received from the smart helmet 100 or the management terminal 300. include

In addition, the call management unit 240 verifies the access rights of the smart helmet 100 and the management terminal 300 attempting to access the communication channel created through the channel management unit 241, and the smart helmet ( 100) or a channel connection management unit 242 that maintains or releases the connection of the management terminal 300 based on the received command signal.

In addition, the call management unit 240 controls the call method and call volume before or during the call process by the smart helmet 100 or the management terminal 300 connected to the call channel created through the channel management unit 241. A call control unit 243 for performing control is also included.

Finally, the dangerous situation management unit 250 detects work image information received from the first communication unit 171 through the server communication unit 210, environment detection information, biosignal detection information, location information, first detection information, and second detection. Analysis is performed to predict the occurrence of a dangerous situation based on at least one of information and third sensing information, and when the occurrence of a dangerous situation is predicted as a result of the analysis, dangerous situation notification information is generated.

More specifically, the criterion information refers to first criterion information for determining whether a feature point extracted from work image information corresponds to a preset level or higher with a feature point reference model for predicting the occurrence of a preset dangerous situation, environment detection Second criterion information for determining whether at least one of the numerical values or changes in the temperature and humidity around the operator according to the information falls within the range of abnormal values for predicting the occurrence of a predetermined dangerous situation or corresponds to an abnormal change pattern, biometric Third decision criterion information for determining whether at least one of the numerical values and changing patterns of the worker's biological signals according to the signal detection information falls within the range of abnormal values for predicting the occurrence of a predetermined dangerous situation or corresponds to the abnormal changing patterns, According to the location information and the third detection information, the position and altitude of the worker are determined by the fourth decision criterion information for determining whether the location and altitude of the worker are closer than the preset distance to the preset danger area within the work area, and the preset detection information from the worker according to the first detection information. Whether or not the movement pattern of the operator according to the 5th decision criterion information, the 2nd detection information, and the 3rd detection information for determining whether or not there is an object that has approached less than the dangerous proximity distance corresponds to the preset abnormal movement pattern and the preset level or more. Corresponds to at least one criterion information among the sixth criterion information for determining whether

Therefore, as a result of performing an analysis for predicting the occurrence of a dangerous situation in at least one of the respective criterion information through the situation prediction part 251, when the occurrence of a dangerous situation is predicted, the situation notification part 252 notifies the occurrence of a dangerous situation. Information is generated and transmitted to the management terminal 300 first.

Following this, the situation notification unit 252 transmits dangerous situation notification information when a dangerous situation propagation request command is received from itself (immediately when the dangerous situation notification information is generated) or from the management terminal 300 to the server communication unit 210.
