The utility model content:
The purpose of this utility model is to solve the aforementioned problems in the prior, a kind of alert reconnaisance flight vehicle of using with infrared distance measuring hovering is provided, be mainly used in the sudden accident scene and scout or survey offender's trend from the high-altitude, transmit the field image data to general headquarters, can realize deciding height in the air and hover automatically.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
The alert reconnaisance flight vehicle of using of band infrared distance measuring hovering, comprise the aircraft body, described aircraft is controlled by remote controller, its bottom is equiped with the high-resolution ccd video camera, be equiped with wireless image-sound transport module and ground-surface video receiver wireless connections in the pick up camera, on aircraft, be equiped with infrared distance measuring height-lock control controller in addition.
Described infrared distance measuring height-lock control controller comprises: infra-red ray transmitting unit is launched infrared ray earthward, receiving element receives the infrared ray that ground is returned, connection survey facies unit, counting unit, logic control element carry out data handing, drive the attitude-control device of aircraft.
Described aircraft adopts four motor driven, and the screw propeller place is provided with circular arc protection structure.
Adopt technique scheme, the utility model is mainly used in the sudden accident scene and scouts or survey offender's trend from the high-altitude, transmits the field image data to general headquarters, realizes when fixed point is scouted that deciding height automatically in the air hovers, conveniently control, adopt the infrared distance measuring data accurately with low cost.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Consult shown in Fig. 1-2, the alert reconnaisance flight vehicle of using of band infrared distance measuring hovering, comprise aircraft body 1, described aircraft is by remote controller 4 controls, its bottom is equiped with high-resolution ccd video camera 2, be equiped with wireless image-sound transport module and 5 wireless connections of ground-surface video receiver in the pick up camera 2, on aircraft 1, be equiped with infrared distance measuring height-lock control controller 3 in addition.
Described infrared distance measuring height-lock control controller 3 comprises: infra-red ray transmitting unit 6 is launched infrared ray earthward, receiving element 7 receives the infrared ray that ground is returned, connection survey facies unit 8, counting unit 9, logic control element 10 carry out data handing, drive the attitude-control device of aircraft.
The design of the utility model aircraft: 1) adopt four motor driven; have a smooth flight; can easily finish various flare maneuvers 2) lithium polymer battery; the time 3 that can fly and reach 45 minutes). screw propeller 11 is respectively equipped with special circular arc protection structure; prevent effectively that blade is impaired, personnel and property escape injury; adopt three-dimensional gyroscope and part of attitude control integrated design, guarantee aerial meticulous location, adopt remote controller to handle control.
Image transmission design: adopt the high-resolution ccd video camera to be installed in the bottom of aircraft, pass real-time video back the ground control point by 2.4G wireless image-sound transport module.
Aerial decide the high controlling Design of hovering automatically: constitute by light modulated (infrared ray) transmitter unit, receiving element, survey facies unit, counting unit, logic control. the real-time measurement of realization distance to the ground, can remote control setting apart from the ground flying height, system realizes deciding the height control of hovering in the air with the automatically regulating flying height and flies.
During work, the aircraft control that will be equipped with four screw propellers by remote controller is taken off, and to the predetermined reconnaissance zone sky, ccd video camera is with the collection in worksite image and send to video receiver so that monitor; When the needs height-lock control, set flying height by remote controller, infrared distance measuring height-lock control controller is started working, by light modulated (infrared ray) transmitter unit launch earthward infrared ray, receiving element receive the infrared ray that returns, by surveying the data handing of facies unit, counting unit, logic controller, the attitude control dress system of direct drive aircraft; Main use alert used the field, satisfies aerial reconnaissance and patrol, especially anti-terrorism, fire alarm, the patrol police of sudden, zonule etc.; Can satisfy simultaneously the needs in fields such as the anti-dangerous disaster relief.
Adopt technique scheme, the utility model is mainly used in the sudden accident scene and scouts or survey offender's trend from the high-altitude, transmits the field image data to general headquarters, realizes when fixed point is scouted that deciding height automatically in the air hovers, conveniently control, adopt the infrared distance measuring data accurately with low cost.
The utility model bases oneself upon sector application, to flight control system, arrives flight load from aircraft itself again, all embodies high reliability, high intelligent characteristics, has powerful technical advantage.By infrared distance measuring, realization aircraft auto-flare system height is analyzed and set to data, more according to the pertinent data inquiry, be blank at present.
