Abstract
The utility model discloses a flying direction measuring device which comprises ground equipment and an air aircraft or a manual carrying instrument device, wherein the ground equipment is composed of a wireless remote control signal receiving and sending machine and can be managed by a computer, and the air aircraft is provided with a CPS positioning instrument managed by the computer, an altimeter, a field-intensity instrument, a radio receiving and transmitting machine and an aerial instrument device. The flying direction measuring device of the utility model remotely controls the aircraft in the sky to make the aircraft advance, fall back, turn, hang and stop along with vehicles by a ground vehicle carrying or a ship carrying or a man carrying remote control devices, a ground remote control device also remotely controls an air direction measuring instrument and aerial operation, measured and controlled information returns the ground and is displayed on a monitoring device, and a whole body which echoes each other at a distance is formed. Remote control signals use electromagnetic waves as a carrier, transmission and reception analog and digital information measure and control antennas to seek targets needing search, commanding direction measurement can be conducted, and the problem that the accuracy of measured directions is influenced caused by that electric waves are blocked by buildings is solved.
Description
Technical field
The utility model belongs to the radio direction finding (RDF) technical field.
Background technology
Existing radio monitoring and direction-finding device is fixedly point type or two kinds of forms of ground moving of ground always.Ground is point type fixedly: the method that adopts monitoring machine room configuration direction-finding equipment, high tower to set up direction-finder antenna solves.Ground moving: configuration is monitored vehicle-mounted or the people is carried form solutions such as equipment.The method of above-mentioned solution direction finding, along with the urban skyscraper emerge intensive, it is more and more ineffective to seem.Skyscraper is more and more outstanding to stopping of electric wave, and the direction finding of searching interference source is more and more difficult.
The utility model content
The purpose of this utility model is to provide a kind of flight direction-finding device, can commanding direction finding, and solve building and stop that electric wave influences the problem of direction finding precision.
The utility model flight direction-finding device comprises uphole equipment and airborne aircraft or manually carries instrument and equipment that uphole equipment is made up of the wireless remote control transceiver; Carry direction-finding device and direction-finder antenna on the airborne aircraft, direction-finding device is made up of with side direction instrument, wireless remote control transceiver GPS orientator, altitude gauge, field intensity meter, is connected with serial port, parallel port, usb mouth and the radio net card of computing machine respectively.Can be with the direction-finding device that carries, be designed to the special-purpose autonomous device combined with single-chip microcomputer, on the aircraft of non-remote control, use.Described aircraft can adopt dirigible or hot air balloon or directly carry the flight direction-finding device with helicopter etc.The flying height of aircraft and the distance of ground remote control point will be within remote control electromagnetic wave coverages, and surpass above ground structure flight.
The utility model flight direction-finding device, carry remote control equipment by ground on-vehicle or boat-carrying or people, the aerial aircraft of remote control advances, retreats, turns and hover with the vehicles, ground remote control equipment is the operation of remote control Aerial Direction Finding instrument and antenna also, returned ground by observing and controlling information and be presented on the surveillance equipment, constitute an integral body that responds to and cooperate with each other across a great distance.It is carrier that remote signal adopts electromagnetic wave, transmit and receive simulation and numerical information, the observing and controlling antenna is sought the target that needs search, but also the direction of manual remote control antenna is carried out level 360 degree, vertical 180 degree are adjusted operation or finished the direction finding operation by the computer software programs automatic measuring and controlling.After the ground remote control transmitter sent command signal, aerial remote-control receiver received instruction and understands, and identified the instruction intention, carried out each generic operation by instruction.

Embodiment
As shown in Figure 1, 2, the 1st, the uphole equipment automobile; The 2nd, the antenna of ground remote control transceiver; The 3rd, airborne aircraft; The 4th, direction-finder antenna; The 5th, direction-finding device.The utility model flight direction-finding device, by ground on-vehicle or boat-carrying or the people is carried remote control equipment and aerial aircraft is formed, uphole equipment is made up of the wireless remote control transceiver, can be by computer control; Carry direction-finding device and direction-finder antenna on the described airborne aircraft, direction-finding device is made up of GPS orientator, altitude gauge, field intensity meter and measuring instrument, wireless remote control transceiver, they are connected with serial port, parallel port, usb mouth and the radio net card of computing machine respectively, and are controlled by computer program.
The flight direction-finding method of using the utility model flight direction-finding device has two kinds:
1, field intensity localization method: driving remotely-piloted vehicle and airborne equipment, bigger around the four crossway line that travels earlier on the highway of noisy city as the region, can carry out in suspicious quadrant interval again that cross is cut apart or suspicious region is carried out square shape around travelling.In driving, the interference field strength signal characteristic at every some latitude and longitude value place is gathered and stored to remote control airborne aircraft airborne equipment, does the storage of interference field strength signals collecting and analyze flight.
2, triangle localization method: as shown in Figure 3, certain A point height value b that calculates according to vertical height aloft, according to direction-finder antenna show to, measure the angle value A of target in certain quadrant area, height value and A point angle value with A point vertical line, obtain the distance that arrives impact point B, according to the right-angle triangle formula: c t gA=b/a computing machine calculate impact point and measurement point apart from OB, deduct the range difference CB that the impact point antenna height produces, obtain the distance of OC, draw corresponding latitude and longitude value at last.
Software: the special purpose computer analysis software, with every some latitude and longitude value of interference field strength, carry out operational analysis.According to radio wave propagation by strong to weak characteristic rule, the latitude and longitude value of the interference field strength signal gathered handed over paints, determine the latitude and longitude value of position of interference source.
Claims (2)
1, a kind of flight direction-finding device comprises uphole equipment and airborne aircraft or manually carries instrument and equipment that it is characterized in that: uphole equipment is made up of the wireless remote control transceiver; Direction-finding device (5) and direction-finder antenna (4) are set on the airborne aircraft (3), direction-finding device is made up of with side direction instrument, wireless remote control transceiver GPS orientator, altitude gauge, field intensity meter, is connected with serial port, parallel port, usb mouth and the radio net card of computing machine respectively.
2, according to the described flight direction-finding device of claim 1, it is characterized in that: aircraft can adopt dirigible or hot air balloon or helicopter.
