The invention relates to the field of flight simulation, in particular to a flight operation task and instrument monitoring task simulation system and method based on a tablet personal computer gravity sensing system.
Background
The flight profession is a special profession, and flight activities are performed under special three-dimensional environmental conditions. The flight mission is complex, the pilot often has to bear the physical limits of high load and large overload, and simultaneously has to rapidly master a great deal of up-to-date scientific knowledge, wherein the double-mission cognitive ability is an indispensable important part. Therefore, the establishment of the flight simulation double-task unit has great significance, and has great research significance and strong application prospect in a plurality of fields such as pilot selection, flight training, fatigue detection and anti-fatigue training.
Currently, flight simulation devices with more applications all need complex hardware devices, such as external devices like operating handles and operating levers. For example, hansa aviation has been used to survey many aspects of psychological quality, such as operational capability closely related to flight, over a three hour period, using dedicated instrument hardware devices for flight simulation tasks for culling. The Chinese civil aviation flight academy also applies the test to the flying work of Chinese civil aviation flight students, but the test efficiency is low, the selection process is seriously influenced, and the test is not popularized on a large scale. The flight simulation software equipment simulates the flight task to a certain degree and plays a role in pilot selection and training. However, since all the devices require special external equipment and must be connected with a high-performance desktop computer, the device has great limitations, which is not convenient for a large number of tests of a group in the election of a pilot, but also convenient for a flight simulation task in the field or parking apron environment with limited external environment, and therefore has great limitations in application and popularization.
A gravity sensor, also called as a gravity sensor, belongs to the novel sensor technology, and adopts an elastic sensing element to manufacture a cantilever type displacement device and an energy storage spring manufactured by the elastic sensing element to drive an electric contact so as to complete the conversion from the gravity change to the electric signal. At present, most of middle and high-end smart phones and tablet computers are internally provided with gravity sensors. The gravity sensor can automatically rotate when the mobile phone is in a horizontal and vertical state, and can replace up, down, left and right during game playing. By measuring the acceleration due to gravity by means of a gravity sensor, the tilt angle of the device relative to the horizontal plane can be calculated.
The invention utilizes the gravity sensing system of the tablet personal computer to simulate flight. On the basis of work analysis of civil aviation pilots, operation cognitive indexes which are most core in requirements on double-task cognitive ability (flight operation tasks and instrument monitoring tasks) in work are extracted, and the flight operation tasks and instrument monitoring task simulation system based on the tablet computer gravity sensing system is provided. A double-task operation mode of an operation task and a monitoring task is adopted, wherein the first task is error control of a flight operation instrument, the aircraft is piloted in six-dimensional space of the upper, lower, left, right, front and back during air piloting, and the second task is monitoring of states of a plurality of instrument indicator lamps. In addition, the test is implemented by adopting a tablet personal computer, a six-dimensional space is simulated by using a gravity sensing system of the tablet personal computer, the sensibility is similar to the driving feeling of a large boeing airplane, the distortion is avoided, and the characteristics of flexibility and rapidness are realized.
