Description

Bridge navigation warning system using biometric information {BNWAS USING BIOMETRICS}

The present invention relates to a bridge navigation warning system using biometric information, and more specifically, to a bridge navigation warning system using biometric information that generates an alarm by grasping the health and working status of the worker by using the biometric information of the worker. .

As the volume of traffic through the ocean increases, the number of ships to handle the volume of traffic is increasing, and due to the increased number of ships, there are frequent cases of accidents during sailing.

As of January 1, 2011, according to Res MSC282(86) adopted by the 86th International Maritime Organization (IMO) Maritime Safety Committee (MSC) to prevent such maritime accidents, warning on the mission of the missionary navigation of SOLAS Chapter V 19 Regulations The mandatory loading requirement for the Bridge Navigational Watch Alarm System (BNWAS) has come into effect.

In order to prevent maritime accidents caused by negligence of watch duty, such as drowsiness and absence of a mission officer during a voyage, the bridge navigation watch alarm system counts down by setting a certain time, and if there is no reset input by the sail watcher until the end, it is normal. It is a device that generates a step-by-step alarm when it is judged that the on-call activity is not performed.

Korean Patent Registration No. 10-1310344 (Sailboat Voyage Watch Alert System) is disclosed.

However, the prior art as described above has the following problems.

According to the Seafarers Act, ship crew members are divided into captains and seamen, and depending on whether they have a license, they can be divided into advanced sailors (commissioned officers) and general sailors, and they can be divided into three fields: navigation/organization/communication. In this way, the ship's crew is divided into each role and class, and the corresponding crew members must be properly placed in their own positions to adequately cope with emergencies, and smooth sailing can be achieved.

However, in the prior art, even if a low-level ship crew member who is unable to work at the corresponding place of work is arranged and worked, the prior art mission warning system may not be properly assigned manpower because there is no separate system for sanctioning it.

In order to solve this problem, Korean Patent Application Publication No. 10-2015-0122358 allows the captain to directly arrange a watch-worker suitable for each work site, and periodically authenticates the watch-worker himself through biometrics, so that the ship can be operated safely. Initiate an alert system on the bridge navigation watch that can be used.

However, there is still a problem in which it is difficult to know whether a worker is able to work properly in a predetermined position.

The bridge navigation warning system according to the present invention includes a wearable device 100 including a sensor that detects a bio-signal including one or more of a worker's blood pressure, heart rate, body temperature, and an electrocardiogram, and a worker receiving a bio-signal from the wearable device. The mobile device 200 may be configured with a mobile device 200 that determines a health state, and a monitoring system 300 that receives information on a worker's health state from the mobile device and generates an alarm when a biological signal is out of a normal range.

The wearable device 100 may be a device worn on a wrist, such as a commercially available Galaxy Watch, and is transmitted to the mobile device 200 by detecting a user's biometric signal. The mobile device 200 may be a personal terminal such as a smart phone.

The wearable device 100 and the mobile device 200 may exchange data with each other through short-range communication such as Bluetooth communication.

The wearable device 100 includes a biosensor that senses one or more of a blood pressure, a heart rate, a body temperature, and an electrocardiogram of a sensor worker.

In addition, the wearable device 100 may further include an acceleration sensor and a gyro sensor for detecting the amount of exercise of a worker.

In addition, the wearable device 100 may further include a speaker and a vibration unit.

In addition, it may further include a display unit for displaying the sensing result, a GPS module, and the like.

When a warning sound is generated from an alarm unit to be described later, the speaker and the vibrating unit may generate a warning sound or vibrate so that a worker can know it.

The mobile device 200 may include a health status determination unit that receives a biosignal from the wearable device and compares it with a biosignal in a normal range to determine the health status of a worker. The bio-signals in the normal range may be stored in the mobile device or may be received from the monitoring system 300. The health state determination unit of the mobile device is referred to as a first health state determination unit to be distinguished from that installed in the monitoring system.

The first health state determination unit may be installed in the mobile device in the form of an app.

The monitoring system 300 receives information on a worker's health status from the mobile device and generates an alarm when the biosignal is out of a normal range.

The monitoring system 300 includes a biometric information storage unit that stores a medical history of an individual worker, a normal blood pressure, a heart rate, a body temperature and an electrocardiogram, and a facial image; An alarm unit generating an alarm sound; A worker authentication unit that photographs the worker and compares the images stored in the biometric information storage unit to verify whether the worker is a worker; A second health status determination unit that compares the biometric information received from the mobile device with the biometric signal stored in the biometric information storage unit to determine the working status and health status of the worker when the worker is authenticated; And a controller configured to store and update the biometric information received from the mobile device in the biometric information storage unit, and control the alarm unit to operate when the biosignal is out of a normal range.

In addition, the biometric information storage unit stores biometric information of workers working in the ship. Each worker's medical history or family history, normal body temperature, heart rate, electrocardiogram (ECG), and a photo of the worker's face are stored, and biometric information received from the mobile device is updated and stored.

The alarm unit is for generating an alarm sound, and may include a first alarm unit for generating a first alarm sound and a second alarm unit for generating a second alarm sound. The first alarm sound is an alarm sound that is generated when a worker's health condition is slightly out of the normal range, and the second alarm sound is an alarm sound that is generated when a worker's health state is much out of the normal range. For example, when the biosignal is out of the normal range by about 10%, a first alarm sound may be generated, and if the biosignal exceeds this, a second alarm sound may be generated.

The worker authentication unit stores a face recognition algorithm, and authenticates a worker by comparing a photographed image received from a mobile device with a face image in which biometric information is stored.

The control unit may control the alarm unit to sound according to the bio-signal received from the mobile device, but control the first alarm sound or the second alarm sound to sound according to a range of the bio-signal. In the case of a worker's negligence such as drowsiness, the first alarm sound may sound, and in the case of unconsciousness or serious condition, a second alarm sound may sound. That is, the control unit may cause the first alarm unit to operate when the biosignal falls within the first reference range, and the second alarm unit to operate when the biosignal falls outside the first reference range and falls within the second reference range. have. The first reference range and the second reference range can be set by an administrator.

The first and second health state determination units may determine whether a worker is in a drinking state or a drowsy state by analyzing a bio-signal received from the wearable device. In general, when you are drowsy, your heart rate decreases by about 10% compared to when you are in a normal state. Therefore, if the heart rate decreases by about 10%, it is determined as drowsy and an alarm sound can be made. For example, if it decreases by 8% to 12% or more from the normal state, it is determined as drowsy, and the first alarm sound sounds, and if it decreases by 13% or more from the normal state, a second alarm sound sounds. Can be done. If it decreases to within 8%, it is judged as a normal state and a separate alarm sound may not be generated.

The second health state determination unit is a sleep analysis algorithm, alcohol analysis algorithm, health abnormal state analysis algorithm, fatigue and psychological state analysis algorithm, work place departure analysis algorithm, exercise amount and life pattern analysis algorithm, guide generation algorithm for crew health management It may include.

The alcohol analysis algorithm may determine whether to drink alcohol based on a worker's behavior pattern. In general, when drinking alcohol, there are characteristics such as not being able to properly control the body or maintaining the same posture. Accordingly, the alcohol consumption analysis algorithm may determine whether the user is drinking alcohol by analyzing a user's behavior pattern received from the gyro sensor and the acceleration sensor.

The second health state determination unit may determine the health state of the worker using the algorithms, optimize the algorithm by referring to data received from the mobile device, and transmit the optimized algorithm to the mobile device. Accordingly, the mobile device receives the optimized analysis algorithm and updates the algorithm of the first health state determination unit.

The initial biometric information stored in the biometric information storage unit may be average biometric information of an ordinary person. In this state, the ID of each worker can be checked from the mobile device, and biometric information for each individual can be optimized and stored. In addition, since the biometric information for each individual may gradually change over time, the biometric information for each individual received may be updated in real time.

The second health state determination unit determines and optimizes the health ecology based on the updated biometric information. The optimized biometric information may be transmitted to the mobile device and stored in the mobile device.

The monitoring system may further include a work information storage unit for storing information on a work schedule, work location, work range, and operation log of a worker.

When a worker is authenticated by the worker authentication unit, the worker and working hours may be updated by automatically storing work-related details in the work information storage unit in the work information storage unit.

The second health status determination unit may receive the location information of the worker from the mobile device, determine whether the worker is in the working position, and control the alarm unit to operate when the worker is not in the working position.

The location of the worker can be determined using a GPS signal and an AP signal of Wi-Fi. In this case, if the amount of exercise is excessively large or there is no movement based on the amount of exercise information received from the wearable device, the alarm sound may be determined as an abnormal state. In particular, if there is no movement at all, there is a possibility of an emergency, so an alarm sound is generated immediately so that the manager can know.

In ships, designated workers must work at designated locations, and violations of this may lead to accidents, so it is necessary to monitor this.

In addition, the controller may receive a bio-signal from the mobile device, analyze a worker's fatigue level, mental state, exercise amount, and life pattern, and update it to be stored in the biometric information storage unit.

The control unit may send a message about a working location, working hours, cautions, etc. before working hours to a working person based on the information in the work information storage unit.

In addition, the controller may control the alarm to sound even when the worker disassembles the wearable device and biometric information is not received.

With the configuration as described above, the monitoring system can prevent an accident by generating an alarm sound when a worker leaves the work place and is not in the correct position, has a poor health condition, or is suspected of negligence.

When an alarm sound occurs, a preset manager can be notified of the alarm occurrence.

In addition, when an alarm sound is generated, the mobile device is transmitted, and the mobile device and the wearable device receive it, so that the worker can guide it with vibration and voice.

The monitoring system may be installed in a ship, and related signals may be transmitted to the outside through the Internet. The same system as the monitoring system can be placed externally and synchronized. Therefore, the control center can also monitor workers' working status and health information in real time.

In the embodiment of FIG. 2, a case in which the health state determination unit is installed in both the mobile device and the monitoring system has been described.

As shown in FIG. 3, the health state determination unit may be installed only in the monitoring system, or may be installed only in the mobile device as in FIG. 4.

Although the embodiments have been described above, these are only examples and do not limit the present invention, and those of ordinary skill in the field to which the present invention belongs are not exemplified above without departing from the essential characteristics of the present embodiment. It will be seen that various modifications and applications are possible. For example, each component specifically shown in the embodiment can be modified and implemented. And differences related to these modifications and applications should be construed as being included in the scope of the present invention defined in the appended claims.
