1. A kind of 1. parabola antenna snow removal system for alarm of snowing, it is characterised in that including:

  • Fan, air channel, spray wind nozzle, shootingHead, three-dimensional head, controller, the identification module that snows, video encoding module, power module, mixed-media network modules mixed-media, cell phone application;

    The fan, air channel, spray wind nozzle are arranged on three-dimensional head, with three-dimensional cloud platform rotation;

    The camera, parabola antenna video image is gathered, on three-dimensional head base, not with three-dimensional cloud platform rotation,Angular field of view includes whole parabola antenna;

    The three-dimensional head, on the outside of parabola antenna, the section with parabola antenna axis is into more than 0 degree and less than 90 degreeAngle;

    The fan, camera, three-dimensional head, the identification module that snows, video encoding module, power module, mixed-media network modules mixed-media and controlDevice processed is connected by signal wire, is controlled by the controller;

    The controller, it is MCU, DSP, FPGA, ARM one kind;

    The identification module that snows, identification of snowing is carried out per two field picture to the parabola antenna video of camera collection;

    The video encoding module, to video carry out real-time coding compression to transmit, coded system for H.264, H.265,Mpeg4 one kind;

    The power module is civil power or solar powered, band battery, be fan, camera, three-dimensional head, controller, underAvenge identification module, video encoding module, mixed-media network modules mixed-media power supply;

    The mixed-media network modules mixed-media, can access LAN or internet, and controller carries out network with cell phone application by mixed-media network modules mixed-media and led toNews;

    The cell phone application, including network detection module, system state module, video module, the alarm module that snows, head are presetPosition setup module, snow removing module;

    The network detection module, the network connection of detection and control device, interruption are then alarmed;

    The system state module, receive the system status information that simultaneously display controller is sent;

    The system status information, includingFan-status, shooting head status, three-dimensional head state, identification module state of snowing, video encoding module state, power module shapeState, mixed-media network modules mixed-media state;

    The video module, the parabola antenna real-time video of display camera collection;

    The alarm module that snows, the warning message that snows that simultaneously display controller is sent is received, automatic start of whether snowing is setSweep away snow;

    The cradle head preset positions setup module, the cruise presetting bit of three-dimensional head is set;

    The snow removing module, sent by mixed-media network modules mixed-media to controller and sweep away snow instruction and stopping is swept away snow instruction;

    The course of work of the identification module that snows is:

    If in upper 2 second in the parabola antenna region of all frames white point pixel mean number be NUM_last2=integer types mostBig value;

    If in upper 1 second in the parabola antenna region of all frames white point pixel mean number be NUM_last1=integer types mostBig value;

    It is continuous to read per two field picture,Such as two field picture is the 1st two field picture in new 1 second, then NUM_last2=NUM_last1, and calculates in upper 1 second and ownWhite point pixel mean number NUM_last1, such as NUM_last in the parabola antenna region of frame<

    NUM_now, then snow, such asNUM_last>

    =NUM_now, then do not snow;

    Such as two field picture is the image beyond the 1st frame in new 1 second, then carrying out black white binarization to current image frame is handledTo binary map, the border of the parabola antenna in binary map is searched, calculates and preserves in the parabola antenna region in binary mapWhite point number of pixels NUM_frame;

    The course of work of the controller is:

    Timing sends system status information to cell phone application;

    The cruise presetting bit for receiving three-dimensional head sets instruction, sets and update the cruise presetting bit of three-dimensional head;

    The image of real-time reception camera collection, point 2 tunnels processing, a route are snowed under identification module progress image recognition whetherSnow, it is to snow that such as continuous 5 seconds, which judge, then sends and snow alarm to cell phone application, and as swept away snow finger there is provided automatic start of snowingOrder, be then transferred to and receive the processing of instruction of sweeping away snow, if do not snowed, do not handle, another way after video encoding module coding compresses, byMixed-media network modules mixed-media sends real-time video code stream to cell phone application;

    Reception is swept away snow instruction, then starts fan, control three-dimensional head to enter cruise mode, travel through each presetting bit, each presetDirectly to the corresponding sub-region in parabola antenna reflecting surface, spray wind nozzle sprays high speed winds and persistently removed the snow, and is delayed, completes in position directionThe operation of 1 presetting bit, the three-dimensional each cruise position of head cruise traversal is controlled, drives spray wind nozzle rotation, target trajectory coveringWhole parabola antenna, status information in progress of sweeping away snow is sent to cell phone application;

    Receive stopping to sweep away snow instruction, then close fan, control three-dimensional head to reset, halted state of sweeping away snow is sent to cell phone application and is believedBreath;

    The course of work of the cell phone application is:

    The network connection of timing detection and control device, such as network connection interruption, then alarm;

    The system status information that timing receipt and display controller are sent;

    The cruise presetting bit of three-dimensional head is set;

    Show the parabola antenna live video image of camera collection;

    The alarm of snowing that controller is sent is received, sound and light alarm, sets automatic start of whether snowing to sweep away snow;

    When needing snow removing, transmission sweeps away snow instruction to controller;

    When terminating to remove the snow, send stopping and sweep away snow instruction to controller.
