Unmanned aerial vehicle's safe control system relates to a unmanned aerial vehicle's safe control system. Mainly that the manual work easily produces the problem design of misjudge and maloperation in the ground remote control when solving current unmanned aerial vehicle flight. The computer and the data logger passing signal line connection of central computer, central computer and the safe server passing signal line connection of carrying out, central computer and flight self -driving appearance passing signal line connection, flight self -driving appearance and communication module passing signal line connection, flight self -driving appearance and differential positioning module passing signal line connection, flight self -driving appearance and single -chip computer passing signal line connection, single -chip computer and throttle server and displacement server passing signal line connection. Data logger's input and the equal passing signal line of the sensor signal input of central computer are connected with the output of installing each sensor on unmanned aerial vehicle. The advantage is judged accurately, and it is accurate to carry out.

Description

A kind of safety control system of unmanned plane

Technical field:

The utility model relates to a kind of safety control system of unmanned plane.

Background technology:

Unmanned vehicle is otherwise known as air-robot.It has maneuverability, reaction fast, the advantage such as unmanned flight, operation requirements be low, not only exhibit one's skill to the full in military domain, also increasingly extensive in the application of civil area, such as on unmanned vehicle, load various sensor, the cruise shooting to appointed area and supervision can be realized.

Be all artificial at ground remote control during existing unmanned plane during flying, control parachute-opening by range estimation with sensation, open air bag etc., easily produce erroneous judgement and maloperation, cause damage.

Summary of the invention:

Technical problem to be solved in the utility model is to provide a kind of precise control, automatically can detect, judge, perform the safety control system of the unmanned plane of safety practice time.

Above-mentioned purpose is achieved in that it comprises central computer, data metering device, communication module, flight autopilot, Secure execution servomechanism, throttle servomechanism, Differential positioning module, one-chip computer, displacement servomechanism;

The computer data output terminal of central computer is connected by signal wire with the input end of data recorder, the Secure execution output terminal of central computer is connected by signal wire with the input end of Secure execution servomechanism, the Fabric Interface of central computer is connected by signal wire with the Fabric Interface of flight autopilot, the flight communications exchange end of autopilot is connected by signal wire with the communications exchange end of communication module, the flight differential signal exchange end of autopilot is connected by signal wire with the differential signal exchange end of Differential positioning module, the flight signal output part of autopilot is connected by signal wire with the signal input part of one-chip computer, the signal output part of one-chip computer is connected by signal wire with the input end of the input end of throttle servomechanism and displacement servomechanism.The input end of data recorder and the sensor signal input end of central computer are all connected by the output terminal of signal wire with each sensor be arranged on unmanned plane, and described each sensor is engine temperature sensing unit, engine speed sensor, state of flight sensor, temperature sensor, fuel sensor, lubricating oil sensor, baroceptor, ultrasonic sensor, GPS sensor, airspeed sensor, voltage-current sensor.

The utility model has the advantages that: by computer controlled automatic, detection, judgement, execution safety practice time, judge precisely, to perform accurately.

Accompanying drawing illustrates:

Accompanying drawing 1 is structural representation of the present utility model.

Embodiment:

With reference to accompanying drawing 1, it comprises central computer 1, data metering device 2, communication module 3, flight autopilot 4, Secure execution servomechanism 5, throttle servomechanism 6, Differential positioning module 7, one-chip computer 8, displacement servomechanism 9;

Control method: detect the attitude of unmanned plane and systematic duty by all the sensors, data recorder is input to and central computer carries out Real-Time Monitoring by the output terminal of each sensor, the data that data recorder record is all are so that later stage Inspection and analysis, central computer contrast detects all data whether in normal range, if attitude mistake and certain sensing data detected extremely, computing machine can judge which position is out of order, and sends corresponding processing signals.

If before taking off fuel or lubricants capacity too low, the data monitoring of computing machine based on fuel sensor or lubricating oil sensor transmissions to fuel or lubricants capacity too low, can start land station's sound and light alarm by communication module, cut off start-up circuit, aircraft engine can not start simultaneously.

Computing machine can calculate the firing rate of flying distance by fuel sensor, differential sensor and airspeed sensor in-flight, when computer monitoring can not be finished the work to fuel or lubricants capacity, computing machine sends instruction refusal task sound and light alarm simultaneously, as strengthened task distance awing, computing machine control flight autopilot starts program of making a return voyage and controls land station's sound and light alarm simultaneously.

If computing machine passes through fuel sensor in-flight, engine temperature sensing unit, voltage-current sensor monitors fuel quantity to be reduced fast, engine temperature is abnormal, electric current and voltage is abnormal, ground control signal is lost, differential signal loss etc., the automatic landing procedure of computer starting, start carry-on sound and light alarm prompting below unit to hide, accelerate landing, after ultrasonic sensor detects ground, fall-retarding, if barrier detected, computing machine controls aircraft by flight autopilot and hides, then to land parking, decline rate is detected by baroceptor.

By state of flight sensor, computer monitoring detects that A axle attitude is abnormal, detect that A shaft generator rotating speed reduces by engine speed sensor simultaneously, computing machine can export a signal continuing to open the throttle to flight autopilot, the throttle servomechanism throttle forward angle controlled by flight autopilot increases engine speed, if engine speed does not increase within a certain period of time, computing machine can judge A shaft generator fault, start safety protection program, land station's sound and light alarm controls two engines adjacent with A axle simultaneously and provides lift, A axle diagonal angle engine keeps attitude of flight vehicle, carry out safe falling, if test pose continues abnormal, the altitude signal of computer monitoring baroceptor and differential sensor, highly allow to send instruction control safety and firing mechanism and close all engines, parachute-opening is force-landed, when highly lower, control to close all engines, open buffer air bag forced landing.
