The embodiment also provides a system for monitoring and reminding the hands-off, which is used for executing the method for monitoring and reminding the hands-off of the implementation example. Referring to fig. 3, the sensing module 20, the grip sensing module 40, and the reminding module 50 of the locking mechanism are all installed in the side bars at both sides, and the data processing module 30 is installed inside the side bar at the left side, and is specifically implemented as follows:
aircraft state awareness module 10: the aircraft is in the ground stage, and the autopilot is always in the off state, so that the unit does not need to be reminded at this time, and therefore, in this embodiment, the ground-air state of the aircraft needs to be sensed by the aircraft state sensing module, so as to provide a ground-air signal to support the data processing module 30 to determine whether the function of the grip sensing module 40 needs to be activated. The module can be a sensor for sensing radio altitude, wheel load, wheel speed, aircraft speed and the like, the sensors can be sensors already installed and used on the existing aircraft, and the radio altitude sensing device can directly sense the altitude of the aircraft from the ground to judge the air-ground state of the aircraft; the sensing wheel-mounted device can judge the air-ground state of the aircraft through the telescopic state of the landing gear piston; the air-ground state of the aircraft can be comprehensively judged through the wheel speed and the ground speed of the aircraft, the aircraft can be judged to be on the ground when the ground speed of the aircraft is 0, and the aircraft can be judged to be in the air state when the ground speed of the aircraft is not 0 and the wheel speed of the aircraft is 0. The embodiment adopts a wheel-mounted device, and the ground-to-air state is judged through the telescopic state of the landing gear piston;
lever lock mechanism sensing module 20: in this embodiment, the left and right side bars are provided with a bar lock mechanism sensing module 201 and 202, when the autopilot is in a disengaged state, the autopilot needs to be taken over manually, and the pilot needs to remind the autopilot if the pilot does not grip the bar, so the embodiment judges whether the autopilot is on or not through the bar lock mechanism sensing module. The present embodiment employs an autopilot locking solenoid installed in the sidebar mechanism, whose electrical signal is monitored to determine the autopilot status; when the automatic driving is on or off, the electric signals on the coils of the two side lever lock mechanisms are synchronously changed, so that the automatic driving on state can be judged only by collecting the electric signals on the coils on one side, and the data processing module 30 is supported to judge whether the function of the holding lever sensing module 30 needs to be activated.
Grip sensing module 40: in this embodiment, the left and right side bars are respectively provided with a grip sensing module 401 and 402 for monitoring the hand-off state of the pilots at both sides, for example, the grip sensing module can be a side bar position sensor or a side bar radial pressure sensor, the side bar displacement signal is obtained through the side bar position sensor, and the side bar grip pressure signal is obtained through the side bar pressure sensor; transmitting the obtained sidebar displacement signal and sidebar pressure signal to the data processing module 30; the data processing module 30 is instructed to activate the grip sensing function and to provide a grip sensing signal to support the data processing module 30 in determining whether the pilot is in a disengaged condition. And (3) injection: the grip sensing module 40 senses the grip state through the sidebar displacement and pressure is only an example of the availability, but the example is not suitable to use the temperature signal, because many pilots are used to wearing gloves to fly in the course of the air route, and therefore, the temperature signal may cause false alarms to trigger frequently. The method adopts a side rod position sensor device and a side rod radial pressure sensor device, and judges the handle bar state of a side rod on one side together through a side rod displacement signal and a side rod radial pressure signal;
data processing module 30: the data processing module in the embodiment is arranged inside the left side rod; the device is used for receiving signals of the aircraft state sensing module 10, the rod lock mechanism sensing module 20 and the holding rod sensing module 40, judging and deciding whether to start a holding rod sensing module 40 hand-off monitoring function according to the signals of the two modules 10 and 20, and further judging and deciding whether to start a reminding module 50 hand-off reminding function according to the signals of the holding rod sensing modules 40 inside the two side rods; and meanwhile, according to the signal states of the aircraft state sensing module 10, the rod lock mechanism sensing module 20 and the holding rod sensing module 40, the monitoring reminding function is inhibited.
The hands-off reminding module 50: for example, a buzzer additionally arranged in the side rod can prompt the current aircraft of the unit to be in a hands-off state through beeping sounds, or an alarm signal trigger sent to the airborne avionics system can prompt the current aircraft of the unit to be in a hands-off state through triggering an alarm (comprising CAS information, a warning lamp and an alarm sound); the hands-free reminder module is activated upon receipt of a start signal from the data processing module 30. The buzzer is adopted in the embodiment, and the current aircraft of the unit is prompted to be in a hands-free state through the buzzer.
