Abstract

PURPOSE:To effectively deal with the swoons and consciousness reduction of a pilot by outputting a blood flow deficiency signal with a blood flow judging means when the size of the downward acceleration G applied to the pilot exceeds the preset value. CONSTITUTION:When the blood flow reaches to a dangerous level by the action of the excessive downward acceleration G and a pilot A swoons as a result, a blood flow deficiency signal S1 and an acceleration excess signal S2 are outputted to an AND circuit 7 from an output judging unit 3 and a G judging unit 6, respectively, and the AND circuit 7 outputs a consciousness loss signal S3 to an automatic pilot 8 for automatic steering. A crash accident or the like can be effectively prevented. No consciousness loss signal S3 is outputted unless the acceleration excess signal S2 is outputted even if the blood flow deficiency signal S1 is outputted, thus the automatic pilot 8 is not easily operated by the noise or the like of the blood flow sensor 1, and the reliability of a system is improved.

[Prior Art] For example, in modern aircraft with high maneuverability, excessive acceleration G acts on passengers when the aircraft performs a sudden maneuver. In particular, when a sudden turn is made, a large downward acceleration G acts on the occupant from the upper body to the lower body, and as a result, the occupant's blood concentrates in the lower body, resulting in insufficient blood flow to the brain. You may experience fainting or near-fainting.

[Effects] If the configuration according to claim 1 is provided, when the blood flow reaches the syncope level due to the action of excessive downward acceleration G and the passenger faints due to this, the blood flow determination means will generate a blood flow insufficient signal. is output. At this time, since the magnitude of the downward acceleration G acting on the passenger exceeds the set value, the acceleration determining means outputs an acceleration excess signal. and,
The unconsciousness determination means that receives both signals outputs a loss of consciousness signal. This allows safety measures to be activated in a timely manner to prevent accidents caused by the passenger's fainting. On the other hand, even if the loss of consciousness signal is output, if the excess acceleration signal is not output, it is not determined that the device is in a syncope state, so that malfunctions due to noise or the like can be prevented.

Furthermore, if the configuration according to claim 2 is provided, the degree and tendency of a decrease in the level of consciousness can be ascertained based on the magnitude of the acceleration G and the blood flow state, so if the blood flow state suddenly deteriorates or the acceleration G suddenly increases. When the level of consciousness increases, for example, it is determined that there is a possibility of syncope, and a decreased consciousness signal is output by the consciousness level determining means in advance. This makes it possible to issue a warning to the passenger and have him or her take appropriate measures to avoid fainting. Moreover, if the safety means is activated after such a warning, the safety means can be activated at a more appropriate time.

The consciousness level determining means 9 is constituted by, for example, a general-purpose microcomputer, and includes a program for predicting a sign of syncope in the passenger A based on the relationship between blood flow and acceleration G, such as their respective magnitudes and fluctuation rates. The data is stored. In other words, the blood flow rate is an index for determining the level of consciousness of passenger A at that time, and the magnitude and rate of increase of acceleration G determines how the environment will change after that and what impact it will have on the level of consciousness of passenger A. This serves as an index for determining whether there is a possibility of fainting, so for example, if a sudden rise in acceleration G occurs even if the blood flow is slightly above the fainting level, it is predicted that passenger A will faint in a few seconds. Then, a decrease in consciousness signal S4 can be output several seconds before the patient faints. This decreased consciousness signal S4 is sent to the warning means 10 which has the function of appealing to the visual and auditory senses of the passenger A to draw attention to the passenger A.
is input to determine passenger A's danger avoidance action. At this time, the warning means 1 is activated by passenger A performing an appropriate operation.
0 to the consciousness level determining means 9, and thereby, if there is no response signal sl within a certain period of time after the warning, the consciousness level determining means 9 determines that the consciousness level determining means 9 has fainted. The operating signal s is sent to the autopilot 8.
6, and the consciousness level determining means 9 may be configured not to operate if there is a response signal. Further, the motion signal s is determined based on the independent judgment of the consciousness level determining means 9.
It is also effective to use a configuration in which 6 is output.

However, if a consciousness detection device having such a configuration is provided, when the consciousness of the passenger A (715) is decreasing due to the action of the acceleration G, the consciousness level determining means 9 can output a consciousness decline signal s4 in advance. Therefore, if left untreated, Passenger A may fall into a state of unconsciousness without realizing it, so appropriate measures should be taken to arouse the passenger's consciousness through warnings and prevent further loss of consciousness. This makes it possible to avoid crashes.Furthermore, if the autopilot 8 is activated after the above-mentioned process, the aircraft can easily perform automatic steering. This ensures proper operation of the safety device.

[Effects of the Invention] According to the invention according to claim 1, when the blood flow toward the brain decreases and the passenger faints, a loss of consciousness signal is output, so that appropriate measures such as activating safety measures can be taken. Measures can be taken and attacks can be effectively prevented. Furthermore, even if a blood flow shortage signal is output simply due to noise, a loss of consciousness signal will not be output unless the acceleration G is large, so that adverse effects caused by malfunctions can be eliminated and reliability can be improved. On the other hand, according to the invention according to claim 2, when there is a risk of the passenger fainting, a signal of decreased consciousness is outputted beforehand, so that it is possible to issue a warning to the passenger and prevent the occurrence of fainting. This makes it possible for people to take appropriate measures to avoid accidents. Further, by activating the safety means after such a warning, a more appropriate timing for operating the safety means can be ensured.
