Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, is intended to be illustrative, and not restrictive, and it is intended that all such modifications and equivalents be included within the scope of the present invention.
In the following detailed description, directional terms, such as "left", "right", "upper", "lower", "front", "rear", and the like, are used with reference to the orientation as illustrated in the drawings. Components of embodiments of the present invention can be positioned in a number of different orientations and the directional terminology is used for purposes of illustration and is in no way limiting.
According to a preferred embodiment of the present invention, a method for monitoring the fatigue state of a flight crew of an aircraft is provided, wherein the flight crew to be monitored each wear a wearable device comprising a physiological characteristic indicator acquisition module configured to be able to acquire a physiological characteristic indicator (also referred to as physiological indicator for short) of the flight crew and a communication module for transmitting data.
Physiological characteristic indicators referred to herein may include, for example, heart rate indicators and electrocardiograms, but other physiological characteristic indicators that may reflect, at least to some extent, the fatigue level of the crew member, such as respiratory rate, are not excluded. It is understood that the heart rate index and the electrocardiogram may be acquired by a sensing device such as a photosensor, an electrocardiograph sensor, etc. disposed in a wearable device (e.g., an electronic watch, an electronic bracelet, etc.) worn by the flight crew.
The method of the preferred embodiment shown in fig. 1 adopts a centralized analysis processing manner for data (i.e., physiological characteristic indicators of the flight crew) collected by the wearable device, whereas the method of the preferred embodiment shown in fig. 2 adopts a distributed analysis processing manner for data collected by the wearable device.
The method of this preferred embodiment as shown in fig. 1 comprises the steps of:
step 101, collecting physiological indexes of the crew locally, wherein the physiological indexes of the crew can be collected by a physiological characteristic index collection module of the wearable equipment;
102, transmitting physiological indexes of the crew, wherein the wearable equipment can transmit the acquired physiological characteristic indexes to a centralized data processing device through a communication module, such as an in-cabin wireless network;
103, remotely analyzing and processing physiological indexes of the unit, wherein the data processing device can judge whether each crew member is in a fatigue state according to an analysis algorithm which is preset in the data processing device and can judge whether the crew member is in the fatigue state based on the physiological characteristic indexes;
104, sending out alarm information through the wearable equipment worn by the user under the condition of judging that the organic group personnel are in a fatigue state; and preferably also the (co) concentration of the (co) polymer,
and 105, under the condition that the crew members are judged to be in the fatigue state, sending alarm information to the wearer by the wearable device with the highest authority level in the wearable devices of the crew members not in the fatigue state.
It is understood that the alarm information in steps 104 and 105 may be edited or generated by the data processing apparatus and provided to the wearable device involved therein, and then the wearable device sends out the alarm information.
The wearable device with the highest privilege level involved in step 105 may be worn, for example, by a captain, deputy, or crew member of the flight crew, so that a particular person of the flight crew (such as a responsible person) is timely made aware of whether other persons of the flight crew are in a tired state. This avoids the risk of the crewmember already in a tired state himself, intentionally or unintentionally, concealing or neglecting his own tiredness. Also, according to this scheme, even when a wearer of the wearable device, for example, a captain himself or herself, who originally has the highest authority level, is in a fatigue state, a warning will be provided to a higher authority of the remaining flight crews, such as the captain or the conductor, to indicate that the captain is in a fatigue state.
For example, the alarm information referred to herein may be provided in the form of voice or sound, or in the form of text display or simple logo image display. For example, a prompt text such as a recommendation that the XX group is already in fatigue, please arrange to alternate rest "may be displayed on the wearable device.
The analysis algorithm in step 103 may be implemented in a variety of ways.
For example, for the processing of heart rate data, according to the training-adaptive theory, as the training level increases, the heart rate tends to decrease gradually when the same exercise load is completed. Generally, if the exercise center rate increases with a constant load of the same intensity, it indicates that the physical function state is not good, i.e., a fatigue state occurs. Thus, in some preferred embodiments of the invention, the motion center rate indicator may be replaced by an immediate or real-time heart rate acquired by the wearable device. The data processing device may have a base heart rate or a baseline heart rate for each crew member. Data processing apparatus is through comparing instant rhythm of the heart with basic rhythm of the heart, if the discovery has obvious increase or instant rhythm of the heart surpasss basic rhythm of the heart and reaches certain range or certain proportion, then judges that this crew member appears fatigue state. It can be understood that, for some other physiological indexes, whether the fatigue state of the crew member occurs can also be judged by comparing the collected indexes with the pre-stored reference indexes in a similar manner as described above.
For another example, for processing the electrocardiographic data, the data processing device compares the acquired electrocardiogram with the stored normal electrocardiogram of the set, and determines whether the electrocardiogram has abnormal changes, such as T-wave falling or inversion, S-T segment downward shifting, and the like. If the change is found, the fatigue state of the unit is judged.
According to some more preferred embodiments, more accurate fatigue judgment algorithms based on heart rate and electrocardiogram indexes can be adopted. For example, the data processor may be configured to execute the fatigue calculation method described in chinese patent CN106326644B entitled "a calculation device for heart rate variability parameters and fatigue indicators", and further determine whether the crew member is in a fatigue state according to the calculated fatigue indicators.
In the above preferred embodiment, it is further preferred that a receiving module is also provided in the wearable device, and the receiving module is set to different authority levels, and accordingly, the alarm information is sent to the receiving module with the highest authority level.
Alternatively, the alert information is generated by a data processing device, a wearable device or a display device therein, or the like, for outputting only the alert information, or outputting the alert information to the wearer.
According to some preferred embodiments of the present invention, the wearable device transmits the physiological characteristic index to the data processing apparatus via an in-cabin wireless network originally provided in the aircraft, and the data processing apparatus transmits the warning information to the wearable device via the in-cabin wireless network. Moreover, the data processing device adopts a processor shared with the original onboard system of the airplane, and the processor is independent of the wearable device. By utilizing the original local area network in the cabin to transmit data and utilizing the original processor resources to process, calculate or analyze the related data, the extra hardware overhead caused by implementing the scheme of the invention on the basis of the existing airplane can be greatly reduced, thereby reducing the overall cost.
As shown in fig. 2, in an alternative embodiment of the present invention, a data processing device is integrated into the wearable device and distributed data processing is employed.
In this alternative embodiment, the method comprises the steps of:
step 101, locally acquiring physiological indexes of a unit;
step 203, locally analyzing and processing the physiological indexes of the unit;
step 204, feeding back fatigue state information (namely alarm information) to the crew member under the condition of judging that the crew member is in a fatigue state;
and step 205, feeding back the fatigue state to the captain or the crew member.
In contrast to the various embodiments described above, in another alternative embodiment according to the present invention, a seat apparatus may be employed instead of a wearable device. Wherein the seat arrangement is configured to be attachable to the crew member to be monitored, i.e. the seat arrangement may be associated with the crew member sitting thereon. The seating arrangement includes a physiological characteristic indicator acquisition module configured to acquire a physiological characteristic indicator of the flight crew and a communication module for transmitting data. Optionally, the physiological characteristic index collecting module or the sensing device specifically adopted by the physiological characteristic index collecting module can be arranged on a chair back part or a cushion part of the seat device, so that when an aircrew sits on the seat device, the physiological characteristic index of the aircrew can be collected. More specifically, in the embodiments of the present disclosure that employ a seat device instead of a wearable device, the physiological characteristic indicator acquisition module may specifically employ a capacitive sensor as the sensing device and arrange it in, for example, a seat cushion portion of the seat device, thereby providing the acquisition of the physiological characteristic indicator of the crew member required in the present disclosure when the crew member is seated on the seat device.
It will be appreciated that the steps and methods involved in this alternative embodiment, including the collection, transmission, analysis processing, provision of alarm information, etc. of the physiological characteristic indicators, may be implemented in the same or similar manner as the related steps and methods described above with reference to the embodiment employing the wearable device. And will not be described in detail herein.
Some preferred embodiments of the present invention also provide a system for monitoring fatigue status of a flight crew of an aircraft.

In the system according to the preferred embodiment of the present invention as shown in fig. 3, a plurality of wearable devices 301 are included, each wearable device including a physiological characteristic index acquisition module, a communication module, and an information output module, and further integrated with a data processing apparatus.

The data processing device is provided with an analysis algorithm for judging whether the flight crew is in the fatigue state based on the physiological indexes in advance, and is configured to be capable of judging whether each flight crew is in the fatigue state by adopting the analysis algorithm and sending alarm information to an information output module of wearable equipment of the flight crew when the flight crew is judged to be in the fatigue state.
For the predetermined analysis algorithm, reference may be made to the foregoing description and illustration of the embodiment of the method for monitoring the fatigue state of the flight crew of the aircraft, and details are not repeated here.
The system also includes an in-cabin data network 303 that the aircraft originally has, such as an in-cabin wireless local area network. The plurality of wearable devices 301 are each communicatively connected via an in-cabin wireless local area network 303.
One major difference of the system according to the preferred embodiment of the invention as shown in fig. 4 compared to the embodiment as shown in fig. 3 is that the data processing means therein is arranged separately from the wearable device 302 and not integrated therein. Each wearable device 302 communicates and transmits data via an in-cabin data network 303 and a data processor 304 (i.e., the data processing apparatus).
On the basis, the data network in the cabin can reuse the existing network in the airplane cabin, and certainly, a network can be established independently for the scheme.
For example, the on-board data network 303 may include the following modules:
a headend interface module for providing an interface for communication with headend equipment (e.g., data processor 304);
and the wireless transmission interface module is used for providing an interface for communicating with the wearable device, namely data interaction.
And the transmission node module is used for providing data transmission in the network.
In addition, the data processor 304 may preferably reuse existing processor or processing resources within the aircraft cabin, thereby saving hardware overhead.
According to some preferred embodiments of the present invention, the wearable device includes a plurality of wearable devices set to have different levels of authority. And the data processing device is also configured to be capable of sending alarm information to the wearable device with the highest authority level in the wearable devices of the aircrews not in the fatigue state under the condition that the aircrews are judged to be in the fatigue state.
In contrast to the embodiments described above with reference to fig. 3 and 4, according to another alternative embodiment of the present invention, a seat device may be used instead of the wearable device, and the modules arranged in the wearable device in the above embodiments, such as the physiological characteristic index acquisition module for acquiring the physiological characteristic index of the crew member, the communication module for transmitting data, and the information output module, may be arranged in the seat device, such as the chair back portion or the seat cushion portion thereof, so that when the crew member sits on the seat device, the seat device can perform the operations of acquisition, transmission, analysis processing, and the like of the physiological characteristic index of the crew member in the same or similar manner as the wearable device in the previous embodiments. Specifically, reference may be made to the description made above for the embodiment including the wearable device, and details are not repeated here.
An application example of the solution according to the above preferred embodiment of the present invention will be illustrated below for ease of understanding.
For example, in this application example, on a long range flight, there are a chief aircraft, a copilot, and an observer. The captain, copilot and observer are each wearing a wearable device, such as an electronic watch.
During the flight, the wearable device of the copilot continuously acquires electrocardiogram indications of the copilot and sends the indications to the data processing device. And after the acquired electrocardiogram indication of the copilot is compared and analyzed with the normal electrocardiogram indication prestored in the database by the data processing device, the electrocardiogram indication is considered to be abnormal, and the condition that the copilot is in a fatigue state is further judged.
In this case, on the one hand, the wearable device of the co-driver scrolls through its display module to display an alarm prompt such as "you are tired and please arrange to alternate to rest" while accompanied by a vibration prompt, and on the other hand, data communication through the in-cabin data network causes the wearable device of the captain to scroll through its display module also to display an alarm prompt of "the co-driver is tired and please arrange to alternate to rest".
After the captain receives the suggestion, can arrange the copilot to have a rest to take over the copilot work by the observer, in order to guarantee the health of unit and continuous flight safety.
In conclusion, according to the scheme of the preferred embodiments of the present invention, the fatigue state of the crew can be effectively and continuously monitored, and the crew is prompted in time to avoid fatigue work, so that the risk of potential safety hazards and even accidents caused by the fatigue state of the crew is reduced and even avoided. Meanwhile, in some preferred embodiments, the further design significantly reduces the hardware overhead or cost required for implementing the scheme of the invention, especially for implementing the invention based on the existing airplane and the existing equipment in the airplane cabin.
