Aircraft emergency control device and control method thereof

Abstract

The invention discloses an aircraft emergency control device and a control method. The aircraft emergency control device includes a communication signal receiving and feedback module (1) and an aircraft control system processor (2); the communication signal receiving and feedback module (1) receives instruction signals sent by a ground base station or instruction signals sent by a satellite, and transmits the received signals to the aircraft control system processor (2); the aircraft control processor system comprises a microprocessor module (3) and an emergency control module (4); and the output end of the microprocessor module (3) is connected with the input end of the emergency control module (4), so that an aircraft can enter a preset emergency flight mode. According to the aircraft emergency control device and the control method of the invention, the communication signal receiving and feedback module is just additionally adopted, and the combinations of various kinds of communication signals or key combinations which are simple in logic are adopted in cooperation, and therefore, flight control can be performed on the aircraft losing remote control signals, and the crash of the aircraft due to being out of control can be avoided.

Problems solved by technology

[0003] The remote control signals of existing multi-rotor aircraft are basically based on radio signals in the frequency band 2.4G, and the remote control equipment has frequency hopping settings to minimize the mutual interference of remote control signals in the same band, but in general, the remote control signals are vulnerable to various obstacles The communication distance is limited, and even with the frequency hopping setting, it is not enough to completely resist the interference of all other remote control signals of the same band

[0004] When the remote control signal of the aircraft is interfered, the aircraft will often lose control and fly away from the set route or area autonomously, eventually leading to flight accidents. According to incomplete statistics, the proportion of such flight accidents is higher than that caused by aircraft hardware failures. The proportion of flight accidents is much higher, which greatly affects the safe use of aircraft

[0005] Most of the existing commercial aircraft, when the remote control signal interferes, first try to repeat the connection manually or automatically. After the repeated connection is successful, you can continue to control the aircraft. Through this button, the aircraft is controlled to fly to a fixed position, so as to avoid the occurrence of flight accidents. Although the above-mentioned technical process looks foolproof on the surface, a large number of flight accident examples after the remote control signal is lost tell us that this design is not 100% % of them work, and the failure rate is quite high. Countless complaints of this kind can be seen from the forum of a famous aircraft company, indicating that the above-mentioned technical process has not fundamentally solved the problem

[0006] In the prior art, it involves the use of GSM communication technology and GPS positioning technology for aircraft self-rescue and recovery. These patents have added GSM transmitters, GPS receiver modules, GPS decoders and other equipment. When the aircraft loses contact, through The GSM transmitter transmits the GPS positioning signal to the user to facilitate the search for the missing aircraft, but in fact, the existing commercial aircraft already has similar functions, and it does not need an independent GSM transmitter module to transmit the GPS signal when the aircraft was last missing. , and even the video signal of the camera equipped on the aircraft is saved and uploaded by various means, and finally provided to the user, so that the user can retrieve the missing aircraft, and many users have already found their lost aircraft through this method. Although this type of technology can provide users with an auxiliary means to retrieve the missing aircraft, it cannot change the reality that the aircraft has disappeared and crashed. What users often find is a damaged aircraft, or even completely unusable. Therefore, This type of technology cannot effectively protect the safe flight of the aircraft
