Abstract

The utility model discloses a Beidou low-altitude flight monitoring system comprising a Beidou command user computer, a 4G communication device, a monitoring processing device, a radar information connection device, and an ADS-B information connection device. The Beidou command user computer, the monitoring processing device, and the 4G communication device are connected successively. The radar information connection device and the ADS-B information connection device are connected with the monitoring processing device. The Beidou low-altitude flight monitoring system is advantageous in that command information can be transmitted to a single aircraft or multiple aircrafts through the Beidou command user computer according to user setting, that self-navigated aircraft circumjacent state information is transmitted to corresponding aircrafts through Beidou short messages, that pilots may know the flight states of aircrafts nearby and execute correct flight operation while knowing the positions of themselves, that flight safety and flight missions are guaranteed, and that the Beidou low-altitude flight monitoring system is suitable for extreme weather especially haze weather and has good practical value and practical significance.

Description

Big Dipper type low latitude operation monitoring system

Technical field

The utility model relates to Big Dipper type low latitude operation monitoring system, belongs to aerospace applications technical field.

Background technology

At present, existing traditional low-altitude surveillance technology mainly relies on to draw and meets secondary radar and ADS-B (Automatic Dependent Surveillance-Broadcast, Automatic dependent surveillance broadcast) information, realizes standardized flight posture monitoring and controlling after processing.

But at present, deficiency and the defect of existing traditional low-altitude surveillance technology are:

1), for the low flyer that does not install secondary radar answering machine and 1090E communication module additional, just cannot obtain flight posture information or the flight path information of aircraft; The restriction that radar information is disturbed by landform and background return, exists and monitors blind area the monitoring of low flyer; Aircraft does not fill 1090E module, cannot realize ADS-B information monitoring; ADS-B land station is not built on ground cannot realize ADS-B information monitoring; Land station's information is not drawn and is connect, and cannot realize ADS-B information monitoring equally.

2) even for the aircraft that can obtain secondary radar flight path information or ADS-B information, because cannot monitoring self flight path, aircraft itself also cannot obtain the flight multidate information of periphery aircraft, therefore, under autonomous visual flight, there is potential safety hazard.

3) current, existing traditional low-altitude surveillance technology can not adapt to the extreme weather situation that particularly haze weather increases.

Utility model content

The purpose of this utility model is to provide a kind of Big Dipper type low latitude operation monitoring system that can overcome above-mentioned technical matters, the utility model is little for low latitude aircraft target, maneuverability is high, independence is strong, be difficult to accurately grasp the dynamic feature of flight, in conjunction with low-latitude flying feature and rely on Big Dipper short message communication function, receive low flyer ADS-C (Automatic Dependent Surveillance-Contract, Automated dependent surveillance contract) independent navigation information, demonstration flight posture is taken into account the monitoring of the empty mood gesture of secondary radar and the empty mood gesture of ADS-B simultaneously, realized veritably the empty mood gesture monitoring of multimode.

The utility model comprises: Big Dipper command type subscriber computer, 4G communication facilities, supervision treatment facility, radar information are drawn the equipment of connecing, ADS-B information is drawn the equipment of connecing; Described Big Dipper command type subscriber computer, supervision treatment facility, 4G communication facilities connect successively; Described radar information draw the equipment of connecing and ADS-B information draw the equipment of connecing respectively with monitor that treatment facility is connected.

Described Big Dipper command type subscriber computer has been used for relying on the air command communication of Big Dipper short message, supervision treatment facility is realized to Big Dipper time service simultaneously, guarantees that system clock is unified;

Described supervision treatment facility is nucleus equipment, and it is for completing processing, analysis and the supervision of all kinds of reception information;

Described 4G communication facilities completes the up-link pattern of relying under mobile 4G pattern, and described 4G communication facilities is mainly for a supplement communication pattern in the situation of Big Dipper short message cycle length;

Described radar information is drawn the equipment of connecing and is connect and pre-service for completing drawing of secondary radar signals;

Described ADS-B information is drawn the equipment of connecing and is completed drawing of ADS-B information and connect and pre-service.

The utility model has the advantages that and can arrange by Big Dipper command type subscriber computer to single frame aircraft or many aircraft mass-sending command informations according to user, independent navigation aircraft periphery situation information is sent to corresponding aircraft by Big Dipper short message, make pilot in clear and definite self-position, also know the flight posture of periphery aircraft and implement correct flight operation, guaranteed the execution of flight safety and aerial mission, can adapt to the extreme weather situation that particularly haze weather increases, there is stronger practical value and realistic meaning.

Accompanying drawing explanation

Fig. 1 is the one-piece construction schematic diagram of Big Dipper type described in the utility model low latitude operation monitoring system.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in detail.As shown in Figure 1, the utility model comprises: Big Dipper command type subscriber computer, 4G communication facilities, supervision treatment facility, radar information are drawn the equipment of connecing, ADS-B information is drawn the equipment of connecing; Described Big Dipper command type subscriber computer, supervision treatment facility, 4G communication facilities connect successively; Described radar information draw the equipment of connecing and ADS-B information draw the equipment of connecing respectively with monitor that treatment facility is connected.

Specific works process of the present utility model is: Big Dipper command type subscriber computer receives aircraft navigation information (ADS-C), sends supervision treatment facility to; 4G communication facilities receives aircraft navigation information (ADS-C), sends supervision treatment facility to; Supervision treatment facility receiving radar information is drawn the radar information that the equipment of connecing is sent to; Monitor that treatment facility receives ADS-B information and draws the ADS-B land station information that the equipment of connecing is sent to; Processing, fusion and comprehensive empty feelings that supervision treatment facility is realized ADS-C, ADS-B, radar information monitor; Supervision treatment facility is realized Flight Safety warning processing, commander's processing according to flight planning and comprehensive empty feelings; Monitor that treatment facility sends to corresponding aircraft by the empty feelings of real-time periphery and command information, instructs aircrew's safe flight.

The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the utility model scope of disclosure; the variation that can expect easily or replacement, all should be encompassed in the protection domain of the utility model claim.
