Lack of sleep can cause military personnel's lack of concentration, slowed reaction time, decreased responsiveness, memory problems, decreased decision-making ability, and other mental disorders. Therefore, the sleep factor should be taken into account in military operations and the risks associated with lack of sleep should be minimized.

  • a body (2) consisting of all kinds of helmets used by military personnel,
  • PCB board (3) which is a layered board with flat, rigid and insulating properties, containing conductors and thin structures, and an EEG sensor,
  • Gyro sensor (5) integrated into the PCB board (3), which measures the external measurements and coordinates of the people wearing the helmet body (2), as well as the independent rotan value, and detects the position information of the people such as sitting, standing, leaning on something.
  • the inventive sleep tracking and warning system (1) has innovative and unique aspects; such as providing real-time physiological and neurological traceability of military personnel in the operational field, following up and analyzing the electrical activities of the NREM sleep stage, which is defined as the first stage of sleep, taking the necessary measures by considering the equivalent product that is currently used in the measurement of damage / impact after brain traumas in the foreign market, minimizing the human factor, which is the main component of all kinds of safety warning systems, specifically for the needs of the defense industry, of the system to be developed.
  • sleepiness One of the most important factors that can affect the performance of military personnel in operational actions that require attention and focus, or in situations that require long-term waiting, follow-up and watch, is sleepiness. It is critical that sleepiness can be monitored and analyzed on the basis of military personnel, in terms of measures to be taken and its consequences. Military personnel performing their field duties under very different geographical, difficult seasonal and atmospheric conditions; as an active precaution against human-induced vulnerabilities and errors, the detection of sleepiness in the phase just before entering the sleep phase and the sleep tracking analysis and warning system (1), which is an active warning system against this detected situation, can fulfill their duties in the most effective and severe conditions.

  • Sleep Onset Latency (SOL) Sleep Start Delay period constitutes the main operating constraint, Autocorrelation Values are determined in the low-class SOL range between 0-0.3, since all the valuations to be made on the basis of the project will be taken while standing and performing a task but these values can be changed optionally.
  • the human nervous system contains nearly ten billion nerve cells. A significant portion of these nerves are located in the brain, while the rest are located in the spine and related nerves throughout the body. Each brain cell communicates with 5000 to 50000 nerve cells. This communication between nerves causes electrical fluctuations in the brain.
  • the electrical activity of the brain changes during sleep and wakefulness, while doing daily activities, looking at a picture or focusing on a task.
  • the starting point for the sleep tracking analysis and warning system (1) which is the subject of the invention, is exactly these electrical activities.
  • the above-mentioned electrical activity changes of the brain are detected by means of the EEG sensor and gyro sensor (5) placed in the helmets/helmets that is to be worn by the users, is the most extreme unit of the system (1), this electrical data is drawn on the server where all the management of the system will be made through the Point to Point WI-FI wireless data transmission system.
  • the terminals (body (2)) will have an Id assignment from the system. In this way, an identity is assigned to the terminal, data is drawn from these defined units and analyzes are made according to this assignment. Since the physical environment where the system (1) will be used is far from the center where the main control unit is located, the PCB board (3) is transferred directly to an RF base station instead of the network and the mentioned base stations can also communicate among themselves and all these base stations are connected to the server. Terminal units can be connected to different base stations and the information of which terminal will be connected to which base can be assigned from the management program.
  • Base stations can transfer the data they receive from the terminal units to the server with a uart converter, thus creating the desired visual and management interface in the Android/Windows environment and transferring the data to the database.
  • the major advantage of this design is that it does not impose an unnecessary load on the network and at the same time, the security level is kept at a high level. In this architecture, RF communication to be used in base stations is also performed securely.
  • the EEG sensor and gyro sensor (5) transfer data to the PCB board (3) on the body (2), the PCB board (3) transfers the data from the EEG sensor and gyro sensors (5) to the RF base station.

From server to base station HelmetID field, unit No. and a few more special fields can be created in line with similar end-user requests.

  • the latest generation EEG sensors that allow dry type, contactless and wireless communication are preferred in the inventive sleep tracking analysis and warning system (1). There are many reasons for choosing this EEG sensor type. First of all, since it is a dry type, some liquids do not need to be applied before each use. Secondly, the ability to transmit data with wireless technology complies with ergonomic requirements.

The temporal and spatial summation of electrical currents originating from postsynaptic potentials is accepted as the source of different electroencephalogram waves. This whole process starts with the detection of Autocorrelation Values of the EEG sensor.
  • a wireless communication protocol must be used between the PCB board (3) and the central software.
  • the communication protocol used should transmit data over long distances with the lowest level of data loss in peripheral environments where military personnel will be present. For these reasons, SPI communication protocol is used during the transmission of the data transferred from the EEG sensor and gyro sensor (5) to the PCB board (3) to the RF base station.
