The control unit 120 controls the environment monitoring module 100 including the sensor unit 140.

Since the environment monitoring module 100 is an apparatus that an operator should carry, it is necessary to periodically charge the power source or replace the battery. If the power is exhausted while the worker is in the workspace, the worker can no longer monitor the air in the work environment or check whether the worker has an accident. Therefore, it is important for the environmental monitoring module 100 to minimize power consumption.

Accordingly, the controller 120 drives the sensor unit 140 according to a predetermined period during connection with the smartphone 10 of the operator, in order to save power consumption due to the driving of the sensor unit 140. [

The predetermined period of time during which the sensor unit 140 is driven may be 1 second to 1 minute or more depending on the situation, and the sensors included in the sensor unit 140 may be driven at different intervals. The control unit 120 may supply power to the sensors of the sensor unit 140 so that the sensor unit 140 is powered on and the sensor unit 140 is activated when the detection values are obtained from the sensors.

The power source (Batterty) of the environmental monitoring module 100 is charged when a charging circuit is connected. An ISL9301 battery charging device may be used for the charge circuit. The battery of the environmental monitoring module 100 may be used as a lithium polymer battery of the 3V / 50mA standard, but this detailed standard may be easily changed as an embodiment.

The power supply of the environmental monitoring module 100 is first transferred to the constant voltage transformer / supply element (VCC LDO) (LDO). The constant voltage converting / supplying element (VCC LDO) can be implemented by SPX3819, and is connected to various configurations of the control unit 120 as a 3.3V specification to supply power. The constant voltage supply / supply element (VCC LDO) directly supplies power to the MCU, supplies 3.3V (VDD) to the LMP91000 device which controls each sensor (red line) (Blue line) as a reference voltage Vref necessary for operation.

The MCU of the control unit 120 is connected to an LMP91000 element for controlling each sensor through a GPIO (General Purpose Input Output), which is a signal input / output port, to perform control. The MCU of the control unit 120 may be implemented as a CC2650 / CC2541 device that controls BLE communication and other peripheral devices.

 The MCU can select and operate the LMP91000 device through the GPIO and I2C.

I2C (Inter Integrated Circuit) is a serial computer bus developed by Philips and is used to connect low-speed peripherals to motherboards, embedded systems, and mobile phones.

Analog to digital conversion (ADC) is an electronic circuit or device that converts an analog electrical signal into a digital electrical signal.

For example, if the remaining amount of the power of the environment monitoring module 100 is less than 10%, if the operator is still staying in the work space, the application 200 may start the driving cycle of the sensor unit 140 set in the controller 120 Can be set to be delayed.

4 to 6, the environment monitoring module 100 may be detachably coupled to the smartphone 10 physically. The environment monitoring module 100 further includes a housing 110 detachably coupled to the smartphone 10 of the operator and supporting the sensor unit 140, the control unit 120, and the communication unit 180.

The control unit 120 and the communication unit 180 may be housed in the housing 110. [

When the sensor unit 140 is received in the housing 110, a hole may be formed in the housing 110 where the sensor unit 140 is housed so that outside air can be circulated. In another embodiment, the sensor unit 140 may be implemented as a sensor disposed outside the housing 110 so that the sensor can be replaced.

The housing 110 may be provided on one side of the smartphone 10 so as to be coupled with the smartphone 10 by pressing the edge of the smartphone 10 as an embodiment for combining the environment monitoring module 100 and the operator's smartphone 10. [ A recessed groove 111 in which a lower portion of the smartphone 10 is seated is formed in the seating groove 111 and is coupled with the housing 110 so as to be pulled downwardly of the smartphone 10 seated in the seating groove 111, And a fixing portion 112 formed with a gripper 113 for catching the upper edge of the smartphone 10.

In another embodiment, the retention of the securing portion 112 in the downward direction may be accomplished by seating the smartphone 10 in the housing 110, manually pulling the securing portion 112, 112 may be fixed by a mechanical device.

In addition, it is preferable that the gripper 113 has a shape that wraps around both upper edges of the smartphone 10 so that the operator's smartphone 10 can be stably fixed.

The fixing part 112 pulls the smartphone 10 from the upper direction to the lower direction and is brought into close contact with the housing 110 so that the smart phone 10 is firmly fixed to the housing 110, The housing 10 can be easily fixed to the housing 110.

In addition, the gripper 113 may be padded with soft material so that the smartphone 10 may not be damaged even if the environment monitoring module 100 coupled with the smartphone 10 is accidentally dropped.

The power supply of the environment monitoring module 100 may be connected to the smartphone 10 of the housing 110 in order to connect the power supply of the environment monitoring module 100 to the smartphone 10 through the input / 10 includes a terminal 182 protruding corresponding to an input / output port of the smartphone 10, and the environmental monitoring module 100 includes a terminal 182 And shares the power source with the smartphone 10 of the worker through the network.

The housing 110 is formed with an opening to allow the movement of the terminal 182 and the terminal 182 is connected to the housing 110 so that the terminal 182 can move in the horizontal direction and the vertical direction in the housing 110. [ Or may be connected to the battery or control unit 120 installed therein by a flexible cable so as to be movable in a hole formed in the housing 110. Since the terminal 182 can be moved, the terminal 182 can be connected to the input / output port even if the size and the size of the smartphone 10 are different.

The power source of the environmental monitoring module 100 can be implemented by a rechargeable lithium polymer battery.

The smartphone 10 can be charged through an input / output port, and when a device such as a flash memory, a mouse, and a keyboard is connected to the input / output port, power can be supplied to the connected device.

If the power of the environment monitoring module 100 is charged through the power of the smartphone 10 when the power of the environment monitoring module 100 is insufficient or when the power of the environment monitoring module 100 is insufficient, Charging is done by the power source so that power can be shared between the two devices.

The physical connection with the smartphone 10 via the terminal 182 of the environmental monitoring module 100 can be selectively performed only when necessary.

The input / output port of the smartphone 10 may be a commonly used micro 5 pin, a lightning 8 pin or a USB-C type port. The terminal 182 of the environment monitoring module 100 may be a smart phone 10, And the terminal 182 can be replaced in response to the input /

The power supply of the environment monitoring module 100 can be charged by a charger of the smartphone 10 by applying a port of the same size as the input / output port of the smartphone 10 to one side of the housing 110 for easy charging .

The environment monitoring module 100 further includes a phone connection sensing unit 150 that detects whether the smartphone 10 is detached from the housing 110 and the operator and transmits a detection signal to the control unit 120, A lamp 170 which is coupled to the outer circumferential surface and is lit when the housing 110 and the smartphone 10 of the operator are physically separated from each other in a state where wireless communication is connected, and a wire 115 fixed to the housing 110 are wound The housing 110 may further include a receiving groove 114 in which the reel 116 is received.

Since the environment monitoring module 100 and the smartphone 10 of the operator can be connected to each other by the short distance wireless communication through the communication unit 180, they can communicate with each other even if the two devices are physically separated.

Therefore, as an example of use, the operator physically separates the environment monitoring module 100 and the smartphone 10 before entering the work space, puts only the environment monitoring module 100 into the space to be entered, It can be used by checking the environmental condition first (see FIG. 7).

The phone connection sensing unit 150 can be applied as a proximity sensor such as a switch that is physically pressed when the smartphone 10 is coupled to the housing 110. When the terminal 182 is configured in the environment monitoring module 100 , It is possible to determine the physical connection state even if the terminal 182 is connected to the input / output port of the smartphone 10.

When the environment monitoring module 100 is first inserted into a space in which an operator enters the work space, the work space may be a dark place without illumination. Therefore, in order to illuminate the entered position, A lamp 170 may be installed on the housing 110 when the environment monitoring module 100 and the smartphone 10 are separated from each other.

The lamp 170 may be composed of a light emitting element such as an LED or the like.

The wire 115 and the reel 116 connected to the housing 110 are configured to easily retrieve the environment monitoring module 100 that has been put into a target site where environmental detection is to be performed.

The wire 115 is preferably wound within the reel 116 and the reel 116 may be configured to automatically wind the wire 115 by including a spiral wound spring- have.

The operator can check the state of the air remotely by sufficiently pulling the wire 115 from the reel 116 and then throwing the environmental monitoring module 100 into the throwing position. If the checked position is a risk of suffocation If the gas is present and can not enter, the environment monitoring module 100 can be withdrawn by pulling the wire 115.

A loop 117 is formed on one side of the reel 116 so as to be hung on clothes or equipment of an operator so that the loop 117 of the reel 116 is hung on the clothes, 110 may be prevented from dropping.

A housing groove 114 for receiving the reel 116 is formed on one side of the housing 110 so that the operator may feel uncomfortable while carrying the environment monitoring module 100. The reel 116 and the wire 115 The reel 116 may be inserted into the receiving groove 114 to improve portability.

When the environment monitoring module 100 is powered by a lithium polymer battery, it is possible to supply more power to the operator's wireless communication with the smartphone 10 than a general small battery. The smartphone 10 of the present invention can communicate more reliably even at a long distance.

In addition, one embodiment of the present invention includes a central control server 400 connected to the application 200 by radio communication to receive detection values of the sensor unit 140 (see FIG. 1).

The central control server 400 has the same configuration as a typical web server that performs functions of a computer in terms of hardware. However, it contains a program module which is implemented in C language, C ++, Java, Visual Basic, Visual C, etc. and performs various functions in software.

The web server is generally connected to an unspecified number of clients or other servers through a network such as the Internet, receives a request for performing a job from a client such as the application 200 or another web server, derives a result of the job, And the computer software (web server program) installed for that purpose.

The central control server 400 may be installed inside the vessel if it is a dried vessel or may be installed outside the vessel if it is being dried.

The application 200 installed in the operator's smartphone 10 communicates with the central control server 400 through wireless communication means such as a wireless telephone network or Wi-Fi.

The central control server 400 is connected to the application 200 installed in the smartphone 10 of the workers who have entered the monitoring target area and collects the information detected through the environment monitoring module 100, .

For example, if an environmental monitoring module 100 detects that there is a risk of suffocation in the area where a worker is located, or if a noxious gas has leaked, the central control server 400 may detect a dangerous situation to all workers or nearby It is possible to notify the application 200 of the operator located.

It is possible to quickly arrange an operator who has an accident through the central control server 400. To this end, the environmental monitoring module 100 further includes a fall detection unit 160 for detecting a physical impact applied to the housing 110 to detect a fall accident of the worker and transmitting the detected amount of physical impact to the control unit 120, 120 transmits an impulse value to the application 200 when the impulse detected by the fall detector 160 is equal to or greater than a preset reference value. The application 200 determines whether a fall incident has occurred using the received impulse value, It can transmit a rescue request to the central control server 400. [

The fall detection unit 160 may be a MEMS (Micro Electro Mechanical System) sensor that detects the acceleration in the three-dimensional direction.

In order to minimize the error in determining whether or not a fall occurred in the application 200, the application 200 compares the amount of change in the value detected by the gyro sensor built in the smartphone 10 of the operator when the impact value is received If the impact value and the change amount of the gyro sensor are equal to or greater than a preset reference, the smart phone 10 outputs a message asking whether or not the fall occurred, and if there is no response to the message for a preset time, And send a rescue request to central control server 400.

Generally, since the smartphone 10 incorporates a gyro sensor, the value of the gyro sensor of the smartphone 10 as well as the fall detection unit 160 greatly changes when an operator falls or falls. Accordingly, the application 200 monitors the amount of change of the gyro sensor of the smartphone 10, detects that the value of the gyro sensor has changed greatly, and also transmits the impact value of the fall detection unit 160 in the environment monitoring module 100 It can be judged that an impact has been applied to the worker.

However, since it is difficult to accurately determine whether an operator has an accident in this way, the application 200 can output a message for receiving feedback of an operator before determining that a fall accident has occurred.

The message for feedback of the operator is a message to touch the button displayed on the display of the smartphone 10 or to lightly tap the environment monitoring module 100 if an accident has occurred through the display or speaker of the smartphone 10 .

If the operator does not provide feedback within a predetermined time after the message is output, the application 200 can automatically send a rescue request to the central control server 400.

At this time, the application 200 may be used to determine whether or not an accident has occurred by monitoring the change of the gyro sensor value of the fall detection unit 160 or the smartphone 10 by an amount of change due to the activity of a general worker .

The central control server 400 receiving the rescue request immediately notifies the surrounding worker that there is an operator who needs the rescue or informs the rescue staff of the fact that the rescue worker can get the rescue quickly in the golden time have.

The presence of multiple bulkheads, such as a ship or an underground facility, or the enclosed space is very limited in the range of the wireless communication. Therefore, it is necessary to install an access point (AP) in various places in the workplace so that the smartphone 10 of the worker can be connected to the central control server 400 through wireless communication.

Accordingly, an embodiment of the present invention provides a lighting system that is connected to a power line installed on a ship and is illuminated, and performs a wireless communication with the application 200 to allow the application 200 and the central control server 400 to communicate with each other. And further includes a beacon (300).

Since the beacon function of the beacon 300 is included in the inside of the ship, it is easy to install the beacon 300 since it is not necessary to separately connect the power line to the AP device.

8, the illumination beacon 300 includes a power input unit 310 for receiving an AC voltage from a power source line, an AD / DC converter for converting an AC voltage to a first DC voltage, And a beacon module 340 connected to the regulator 330 for receiving a second DC voltage and using a BLE (Bluetooth Low Energy) protocol based near field wireless communication do.

The power input unit 310 may receive a generator installed in an offshore structure or an externally generated AC voltage. The AC voltage refers to a commonly used AC voltage such as 110V or 220V.

The AC / DC converter 320 converts the input AC voltage into a first DC voltage. At this time, the AC / DC converter 320 is connected to the power input unit 310 to receive the AC voltage. Here, the first direct current voltage means a direct current voltage required for the illumination 20 to operate. Therefore, it is preferable to set the first DC voltage converted by the AC / DC converter 320 differently according to the type of the illumination 20 used in the offshore structure. In addition, the illumination 20 means any means capable of emitting light using electricity such as an incandescent lamp, a fluorescent lamp, and an LED lamp 170.

For example, when the AC voltage supplied to an offshore structure is 220V and the illumination 20 used is a fluorescent lamp driven by a DC voltage of 12V, the AC / DC converter 320 receives an AC voltage 220V from the power input unit 310 Receives the input, converts it to a DC voltage of 12V, and supplies it to the illumination unit 20.

The regulator 330 receives the first DC voltage and converts the first DC voltage into a second DC voltage. Here, the second direct current voltage means a direct current voltage required for operation of the beacon module 340. Therefore, it is preferable to set the second DC voltage converted by the regulator 330 differently depending on the type of the beacon module 340 used in the offshore structure.

For example, when an AC voltage supplied to an offshore structure is 220V, and the lighting 20 used therefor is driven by a DC voltage 12V and the beacon module 340 is driven by a DC voltage 3V, the AC / 220V and converts the DC voltage to 12V and supplies the DC voltage 12V to the lighting unit 20 to operate the lighting unit 20. The regulator 330 receives the DC voltage 12V converted and output by the AC / DC converter 320, DC voltage of 3V and supplies it to the beacon module 340.

The beacon module 340 is connected to the regulator 330 and receives the second DC voltage.

The beacon module 340 is a device that transmits a certain signal with a specific frequency to enable a user to locate a user within a certain range and to transmit a message. As described above, since the main power source of the beacon module 340 according to an embodiment of the present invention is not a battery but an electric power that is always supplied from an AC voltage by being converted into a second direct current voltage, Of the beacons installed in the offshore structure of the battery does not have to check and replace each one is easy to manage. Also, since the beacon module 340 receives the power of the illumination 20, which is relatively much larger than the conventional beacon using the battery, the beacon module 340 can transmit and maintain the signal at a maximum intensity, Suitable.

In particular, the beacon module 340 can adjust the second DC voltage output from the regulator 330 to adjust the signal intensity. Thus, by adjusting the output voltage of the regulator 330, the beacon module 340 can adjust the sensing range of the portable terminal.

In another embodiment of the present invention, the beacon module 340 may use short-range wireless communication based on Bluetooth low energy (BLE) protocol.

Accordingly, while the beacon module 340 can grasp the indoor location using the GPS, the beacon module 340 enables the indoor and outdoor workers to be located within a radius of about 50 to 70 m, and the BLE beacon detection of the smartphone 10 is low- So that it is possible to grasp a precise position.

In another embodiment of the present invention, the beacon module 340 may include an auxiliary battery for storing the auxiliary power from the second direct voltage. Even if electricity is not supplied to the power input unit 310, it is possible to install the auxiliary battery in the beacon module 340 so that the beacon module 340 Can be continuously maintained. Thus, even if an accident occurs and electricity is cut off to the offshore structure, the beacon module 340 continuously operates using the auxiliary battery, so that the position of the operator can be quickly detected and secured.

At this time, the beacon module 340 may charge the auxiliary battery when the AC voltage is supplied to maintain the auxiliary power, and operate the auxiliary battery when the AC voltage is interrupted. When the power supply to the power input unit 310 is stopped, the beacon module 340 operates using the power of the auxiliary battery. When the power supply to the power input unit 310 is started again, And the auxiliary battery is charged. When the power supply to the power input unit 310 is smooth, the beacon module 340 periodically checks the remaining amount of the auxiliary battery. If the auxiliary battery is discharged, the beacon module 340 maintains the standby mode in the buffered state. The standby mode is maintained. Since the charging of the auxiliary battery can be efficiently managed, the beacon module 340 can be operated for a long time even if the time during which electricity is not supplied to the power input unit 310 due to an accident occurs in the offshore structure is maintained for a long time, Since the operator 340 can continuously grasp the position of the operator, the life structure can be effectively performed.

In another embodiment of the present invention, the regulator 330 may be connected to the AC / DC converter 320 to receive the first DC voltage.

For example, when an AC voltage supplied to an offshore structure is 220V, and the lighting 20 used therefor is driven by a DC voltage 12V and the beacon module 340 is driven by a DC voltage 3V, the AC / DC converter 320 is connected to the output terminal of the AC / DC converter 320. The AC / DC converter 320 converts the DC voltage into a DC voltage of 12V, And converts the DC voltage to 3V and supplies the DC voltage to the beacon module 340. [

In another embodiment of the present invention, the beacon light 300 further includes an output unit 350 for supplying a first voltage to the illumination unit 20, and the regulator 330 is connected to the output unit 350, DC voltage may be input.

For example, when an AC voltage supplied to an offshore structure is 220V, and the lighting 20 used therefor is driven by a DC voltage 12V and the beacon module 340 is driven by a DC voltage 3V, the AC / 220V is converted into a DC voltage 12V and supplied to the lighting unit 20 to operate the lighting unit 20. The regulator 330 is connected to the output unit 350 that supplies the DC voltage 12V to the lighting unit 20 The DC voltage 12V output from the output unit 350 may be received and converted to a DC voltage of 3V to be supplied to the beacon module 340. [

As described above, the regulator 330 includes a configuration that receives and converts the voltage output from the AC / DC converter 320 to use the beacon module 340 and the configuration in which the output unit 350 that supplies the first voltage to the illumination unit 20 The beacon module 340 may be replaced by a beacon module 340. The beacon module 340 may include a beacon module 340 that converts a voltage output from the beacon module 340, And 340 may be supplied with various power sources.
