Abstract

The invention provides an electronic sighting device used for parabolic ballistic trajectories. On one hand, a processor calculates the simulated paths of cannonballs in ideal states according to linear distances, horizontal height differences, environmental temperatures, wind power, wind power parameters and cannonball models. On the other hand, the processor searches mapping tables among the cannonball models, the environmental temperatures, the wind power, the wind power parameters and offsets and determines offsets under corresponding environmental conditions.

According to the electronic sighting device, the simulated paths of the cannonballs are determined through fitting a numerical calculation mode and a table searching mode, ballistic trajectory calculating efficiency and precision are greatly improved, and the real-time generation of the corresponding parabolic ballistic trajectories can be basically realized.

Description

A kind of electronic sighting device for parabolic trajectory
Technical field
The present invention relates to a kind of sighting device, particularly a kind of electronic sighting device for parabolic trajectory.
Background technology
People are in order to improve efficiency and the precision of shooting, for many years, invented various instrument and equipment and helped User is by rifle run-home.Numerous aiming equipments for rifle, simple for, common being divided into is looked in the distance formula gun sight (Telescopic Sight) and reflecting sight (Reflex Sight) two kinds, also have the aiming of the principle design based on other Device, different sighting instruments lays particular emphasis on the problem solving different aspect.
One sight, one core, it is to aid in user and hit potential target accurately, easily and quickly.
One sight, its another one core, is to make user clearly observe potential target.
Prior art one [CN201010511597] discloses a kind of electronic sighting device, by camera lens, imageing sensor, process Device, memory, display and touch-screen composition.First, being applied in combination of zoom lens and sensor so that putting of sight Big multiplying power has thoroughly broken away from traditional constraint rotating adjusting focal length acquisition enlarged drawing picture by enlargement ratio ring for the formula gun sight of looking in the distance, The sight producing high zoom ratios is become a reality.The creation of this thinking so that user can obtain existing gun sight very Unobtainable high magnification, makes precisely to hit potential target and becomes a reality.Secondly, it is integrated with electronic range measurement performance and wind speed is visited Surveying sensor, the ballistic curve of different bullets is pre-stored in memory, sight when electronic range measurement and wind speed detecting function are opened, When user with sight lock onto target after, processor can in conjunction with these three data, automatically judge aiming point, make automatic aiming become For reality.
The open a kind of electronic type rifle gun sight graticle of prior art two [201210499955] shows and calibration apparatus, mainly by Micro display screen, video driver circuit, power supply and key switch composition.Described video driver circuit include microprocessor, five to by Key, external memory storage, laser ranging unit, wind sensor, Temperature Humidity Sensor and wireless communication module.Microprocessor control Micro display screen processed shows division line, regulates position on screen for the division line by five to button, and the trajectory regulation of this kind of electronic type carries The high stability of zero-bit.Micro display screen shows the level of division line, offset of vertical numerical quantity in real time, and external memory storage can store up Deposit the above-mentioned numerical value of many groups to call for user, save trajectory regulating time.Laser ranging unit, wind sensor, humiture Sensor and wireless communication module connect microprocessor, in real time to micro display screen output target range, wind-force value, warm and humid angle value and Graph text information, is that user obtains environmental data while aiming at and rear information is provided convenience.
Prior art one and prior art two exist two technological deficiencies, first, thinks highly of the bullet storing different bullets in storage Road curve and respective value are called for user, seem that to directly invoke storage simple and practical, but in actual application environment, due to Weapon is of a great variety, and rough segmentation is rifle class and big gun class, and their ballistic curve exists significantly different, by the shadow of the interference of extraneous factor Ringing also different, such as, same wind is just significantly different on the trajectory impact of different weapons, therefore deposits in simple memory The mode of storage data call, error is relatively big in actual applications, substantially cannot meet target;Secondly, of the prior art Though display unit can demonstrate target pattern, but all cannot accurately demonstrate ballistic curve, and simulation hit the mark complete Process, observing gets up similarly is that whether telescopic observation hits the mark, and can only see result after practicing shooting and finish in shooting range, Process cannot be seen, owing to cannot record and observe whole shooting course, namely cannot learn actual shooting trajectory and simulation Difference between trajectory, it is impossible to back-end data is corrected.
Based on drawbacks described above present in prior art, the invention discloses a kind of electronic sighting device for parabolic trajectory, its On the one hand processor according to air line distance, difference in level, environment temperature, wind-force, wind direction parameter and model of shell, calculates Going out ideally shell simulated route, on the other hand, processor is searched according to model of shell, environment temperature, wind-force, wind direction Mapping table between parameter and side-play amount, determines the side-play amount under the conditions of respective environment, then according to ideally parabola side Journey and described side-play amount matching determine shell simulated route, and control touch display screen and show shell simulated route and quilt simultaneously The optical image of run-home.After reality shooting completes, collect actual trajectory and processor calculates the trajectory simulation determining Route is compared, and is corrected back-end data or supplements and storage, in order to shooting can accurately hit later.
