As shown in Figures 2 and 3, when unmanned plane detects smog, described airborne processor module controls unmanned plane and spirals (being gradually reduced the scope of spiraling) around smoke region to lock current smoke region, and behind locking smoke region, unmanned plane enters smog district, and dive downwards, adjust flight attitude makes unmanned plane fly nearly smog generation area all the time in smoke zone simultaneously, namely when unmanned plane is in process of subduction, if Smoke Detection sensing unit detects when unmanned plane departs from smoke zone, revise flight attitude, so that unmanned plane is maintained in smoke zone (when being embodied as, can pass through to adopt the video of shooting, picture and Smoke Sensor carry out real-time judge), fly nearly smog gradually and area occurs, after unmanned plane arrives certain altitude, area is occurred to lock smog, and occur the exact position in area to be sent to base station server smog.
The adjustment of described flight attitude can be realized by the gyroscope being connected with airborne processor module.
Wherein, the method for locking can adopt airborne heat sensor that target is locked, or by aerial device lock artificially, it would however also be possible to employ target is carried out self-locked by image procossing (or by artificial long-range Real Time Observation to video, picture); Obtaining smog occurs the method for regional exact position include and be not limited to: after unmanned plane locks smog generation area (place such as building, building site), fly to smog positive overhead, area, record and occur the exact position in area to be sent to base station server currently without man-machine position as described smog.
Occurring the method in area to obtain smog at smoke zone close to smog by unmanned plane the exact position in area to occur, effectively avoids when haze occurs, unmanned plane cannot be accurately positioned the problem that area occurs smog in high-altitude.
Described unmanned plane is also with aerial device, and video of taking photo by plane sends to base station server; Described smog Long Range Detecting and Ranging also includes: with the onboard navigation system of base station server radio communication; Described onboard navigation system is suitable to occur the exact position in area to guide vehicle to sail this area into as target location according to the smog that unmanned plane sends; Described onboard navigation system includes: in-vehicle processor module, the automotive positioning module that is connected with this in-vehicle processor module, data memory module; Described data memory module storage has map datum, vehicle radius of turn data; Described in-vehicle processor module is suitable to according to vehicle current location and target location, and the radius of turn data schema guidance path in conjunction with Current vehicle.
By described aerial device, the staff at base station server can clearly check the reason that smog occurs, or factory pollutes, or fire, or burn away the refuse, in order to appoint corresponding vehicle to process, for instance fire fighting truck, ambulance or corresponding enforcement vehicle.
Quickly vehicle can will be appointed to sail to scene by described onboard navigation system.
Described airborne, in-vehicle processor module is for example with embedded chip, and described in-vehicle processor module is also connected with touch screen, in order to carry out corresponding input operation and display.
Concrete, described vehicle radius of turn data include but not limited to the data such as the length and width of all kinds vehicle, wheelbase, vehicle turn radius; Described processor can input vehicle by interpersonal interactive interface, and searches the radius of turn data matched with this vehicle from vehicle radius of turn data, and using these radius of turn data important evidence as navigation programming guidance path.

Or for Fig. 4, if the path setting vehicle current location A to objective B has: ACDFEB, AKJIHGB, ACDFIHGB, if turning section H is unsatisfactory for Current vehicle radius of turn requirement, and owing to D section gets congestion, causing after radius of turn correction also cannot vehicle turn radius requirement, then this navigation system plans guidance path again, i.e. AKJIFEB, to meet vehicle pass-through requirement.
Wherein, real-time road can be obtained from road monitoring server by wireless module. Described wireless module can adopt 3G/4G module.
Described in-vehicle processor module is also connected with back wheels of vehicle steering; When vehicle is after entering bend, in-vehicle processor module is according to this bend section obtained from map and in conjunction with current vehicle speed, on the basis of front-wheel steer, automatically adjusts the steering angle of trailing wheel, namely realizes vehicle when turning to, and trailing wheel is prenex.
