Description
Technical field
The present invention relates to a kind of sighting devices, especially a kind of electronic sighting device for parabolic trajectory.
Background technology
People are in order to improve the efficiency and precision of shooting, for many years, invented various instrument and equipments
To help user by rifle run-home.Numerous aimings for rifle are equipped, it is simple for, the common formula of looking in the distance that is divided into is taken aim at
Two kinds of quasi- mirror (Telescopic Sight) and reflecting sight (Reflex Sight) are also had and are designed based on other principles
Sighting device, different sighting instruments, which is laid particular emphasis on, solves the problems, such as different aspect.
One sighting device, one core are to aid in that user is accurate, easily and quickly hits potential target.
One sighting device, another core are user to be made clearly to observe potential target.
The prior art one【CN201010511597】A kind of electronic sighting device is disclosed, by camera lens, imaging sensor, processing
Device, memory, display and touch screen composition.First, zoom lens and sensor are applied in combination so that the amplification of sighting device
Multiplying power has thoroughly broken away from the constraint that traditional formula gun sight of looking in the distance obtains enlarged drawing by the rotation adjustment focal length of enlargement ratio ring,
So that the sighting device of production high zoom ratios becomes 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, electronic range measurement performance and wind speed are integrated with
The ballistic curve of detection sensor, different bullets is pre-stored in memory, and sighting device is opened in electronic range measurement and wind speed detecting function
Qi Shi, after user's sighting device lock onto target, processor can judge aiming point automatically in conjunction with these three data, make automatic
Aiming becomes a reality.
The prior art two【201210499955】A kind of electronic type rifle gun sight graticle is disclosed to show and calibration apparatus, it is main
It to be made of micro display screen, video driver circuit, power supply and key switch.The video driver circuit includes microprocessor, five
To button, external memory, laser ranging unit, wind sensor, Temperature Humidity Sensor and wireless communication module.Microprocessor
It controls micro display screen and shows division line, position of the division line on screen, the trajectory tune of such electronic type are adjusted by five-way button
Section improves the stability of zero-bit.The level of micro display screen real-time display division line, offset of vertical numerical quantity, and external memory
Multigroup above-mentioned numerical value can be stored to call for user, save trajectory regulating time.Laser ranging unit, wind sensor, temperature
Humidity sensor and wireless communication module connect microprocessor, in real time to micro display screen output target range, wind-force value, humiture
Value and graph text information obtain environmental data while aiming at for user and rear information are provided convenience.
There are two technological deficiencies in the prior art one and the prior art two, first, think highly of in storage and store different sons
The ballistic curve of bullet and respective value are called for user, seem that directly invoke storage simple and practical, but in actual application environment
In, since weapon type is various, rough segmentation is rifle class and big gun class, their ballistic curve is there are significantly different, by extraneous factor
The influence of interference is also different, for example, same wind is just significantly different on the influence of the trajectory of different weapons, therefore by simply depositing
The mode of data call is stored in reservoir, error is larger in practical applications, can not meet target substantially；Secondly, existing
Though can show target pattern in the display unit in technology, it all can not accurately show that ballistic curve, and simulation are hit
The overall process of middle target, it is like after shooting range is practiced shooting that observation, which is got up, and whether telescopic observation hits the mark, can only
See as a result, can not see process, due to can not record and observe entire shooting course, that is, can not learn practical shooting
Difference between trajectory and simulating trajectory can not be corrected back-end data.
Based on drawbacks described above existing in the prior art, the invention discloses a kind of electronic aimings for parabolic trajectory
Device, processor on the one hand according to air line distance, difference in level, environment temperature, wind-force, wind direction parameter and model of shell,
Ideally shell simulated route is calculated, on the other hand, processor is searched according to model of shell, environment temperature, wind-force, wind
To the mapping table between parameter and offset, the offset under the conditions of respective environment is determined, then according to ideally parabolic
Line equation and offset fitting determine shell simulated route, and control touch display screen while showing shell simulated route
And it is aimed the optical image of target.After the completion of actually shooting, collects actual trajectory and processor calculates determination
Trajectory simulated route is compared, and is corrected or supplements to back-end data and stores, and can accurately be hit to shoot later
Target.
