Background technology

It is a kind of novel artificially triggered lightning means that metal wire draws the thunder bullet, at proper height, controls and to draw the thunder bullet to carry out the operation of metal wire unwrapping wire be to determine to draw one of key factor of thunder operation success.The time delay line-putting method that tradition is drawn the thunder bullet is, at first the Best Times started according to the corresponding relation computation delay that draws thunder bullet ballistic ordinate and flight time, by set-up time time-delay fuze within drawing the thunder bullet, by the start-up time delay calculated, before emission, bind in advance in angle of incidence time-delay fuze, draw thunder bullet time from launch time-delay fuze and start timing, start the metal wire unwrapping wire after reaching the ticket reserving time, complete and draw the thunder operation.But increase along with drawing the thunder bullet flight time, and then the impact that has strengthened the objective factors such as trajectory environment, make the flight time calculate that the error of ballistic ordinate increases thereupon, traditional time delays fuse has become as drawn the civil rocket bullet such as thunder bullet to important restraining factors in the tele direction development.

The utility model content

The purpose of this utility model is to calculate that by the flight time error of ballistic ordinate can increase along with the increase of range in order to solve traditional time delays fuse, thereby provide a kind of time-delay fuze according to setting height igniting, the large problem of metal wire unwrapping wire height parallax error while avoiding long-range delivery to draw the thunder bullet.

The purpose of this utility model is achieved through the following technical solutions:

A kind of time-delay fuze according to the setting height igniting of the present utility model, comprise height judge module, bookbinding module, gps satellite locating module, start module,

The gps satellite locating module is measured and is drawn the residing height above sea level of thunder bullet in real time, and this height above sea level data transmission module is passed to the height judge module;

The bookbinding module receives the elevation information bookbinding, and this altitude information is transferred to the height judge module;

The height judge module stores bookbinding module height comparison information, and receive in real time the height above sea level information of gps satellite locating module, when the height above sea level information that judgement gps satellite locating module imports in real time meets the height comparison information of bookbinding module, to starting module, send enabling signal;

Instant control point ignition circuit igniting after the enabling signal of startup module reception height judge module;

The bookbinding module is connected with the height judge module by data wire respectively with the gps satellite locating module, and bookbinding module and gps satellite location are respectively to height judge module transmission elevation information; The height judge module is connected with the startup module by data wire, and the height judge module sends enabling signal to starting module; Start module and be connected with the starting switch wire of firing circuit, the starting switch that starts the module controls firing circuit is opened.

The course of work

Before drawing the emission of thunder bullet, by bookbinding module bookbinding height comparison information, the bookbinding module sends to the height judge module by the height comparison information, and the height judge module is stored this height comparison information; The gps satellite locating module is measured and is drawn the residing height above sea level of thunder bullet in real time, and this height above sea level data transmission module is passed to the height judge module, when the height above sea level information that height judge module judgement gps satellite locating module imports in real time meets the height comparison information of bookbinding module, to starting module, send enabling signal; Start instant control point ignition circuit igniting after the enabling signal that module receives the height judge module, and then complete and draw the thunder operation.

Beneficial effect

Time-delay fuze of the present utility model, abandoned in traditional fuse by the mentality of designing of Preset Time starting ignition, solved at all and calculated the technological difficulties that the error of ballistic ordinate can increase along with the increase of range by the flight time, the utility model can be widely used in the delayed firing of civil rocket bullet.
