Abstract
The utility model provides a laser night -time vision device that can show azimuth coordinate and coordinate automatic correction of, including installation guard shield and yun tai together, parallel placement guard shield mainboard PCB in the guard shield, install master control MCU and MENS sensor on the guard shield mainboard PCB, MENS sensor internal integration 3 axle magnetometer and 3 gross rail load on axles power accelerometer, the MENS sensor is communicated through I2C with master control MCU, guard shield mainboard PCB is through interface connection camera, camera lens, laser instrument, focusing component on it. Compared with the prior art, the utility model discloses has following advantage: the magnetometer of this scheme through using the high accuracy and gravity accelerometer sensor come the horizontal position and the vertical angle of automatic correction of laser night -time vision device, do not need artifical the correction, also do not need equipment to restart the self -checking and solve the accumulated error, can horizontal position of accurate demonstration and vertical angle, remove loaded down with trivial details maintenance from.
Description
Technical field
This utility model belongs to commanding elevation monitoring device technical field, especially relate to a kind of can be with display orientation coordinate and coordinate from the laser night-vision device of dynamic(al) correction.
Background technology
Laser night-vision device monitoring distance is remote, wind resistance grade is high, therefore in commanding elevation, city, forest fire protection, monitoring field, sea application widely, at these monitoring scenes, video monitoring background is more single, usually not significantly terrestrial reference, when a fault occurs, staff is needed to confirm, by coordinate information on display screen, the position that current accident occurs, it is simple to process scene in time.
The coordinate of the most commonly used laser night-vision device shows that needing staff that The Cloud Terrace level forwards to after equipment completes self-inspection the positive north in advance carries out directional correction again, but owing to monitoring scene background is single, do not have obvious terrestrial reference, staff accurately can not find the positive north to carry out directional correction from monitored picture, and i.e. enable and accurately find the positive north to carry out directional correction, because The Cloud Terrace long-play has cumulative errors, cause level orientation and vertical angle inaccuracy, need equipment to restart self-inspection staff to re-calibrate, safeguard fairly cumbersome.
Summary of the invention
In view of this, this utility model is directed to a kind of can to show laser night-vision device current monitor orientation, it is possible to solve The Cloud Terrace angle coordinate cumulative errors problem with display orientation coordinate and coordinate from the laser night-vision device of dynamic(al) correction.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
A kind of can be with display orientation coordinate and coordinate from the laser night-vision device of dynamic(al) correction, including the guard shield being installed together and The Cloud Terrace, guard shield mainboard PCB it is placed in parallel in described guard shield, main control MCU and MENS sensor are installed on described guard shield mainboard PCB, the integrated 3 axle magnetometers of described MENS sensor internal and 3 axle gravity accelerometer, MENS sensor is communicated by I2C with main control MCU；
Described guard shield mainboard PCB connects video camera, camera lens, laser instrument, focusing component by interface thereon.
Further, described guard shield mainboard PCB connects the The Cloud Terrace mainboard installed on The Cloud Terrace also by serial ports, installing cradle head control MCU on described The Cloud Terrace mainboard, described cradle head control MCU connects the horizontal step motor of installation, vertical step motor, Horizontal limiting, the most spacing and interface board on The Cloud Terrace.
Relative to prior art, this utility model has the advantage that
This programme is by using high-precision magnetometer and gravity accelerometer sensor from the level orientation of dynamic(al) correction laser night-vision device and vertical angle, need not manual synchronizing, self-inspection is restarted to solve cumulative errors also without equipment, can accurately show level orientation and vertical angle, remove loaded down with trivial details maintenance from.
Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 be described in this utility model embodiment can with display orientation coordinate and coordinate from the laser night-vision device of dynamic(al) correction and structure principle chart.
Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in this utility model and the feature in embodiment can be mutually combined.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Can be with display orientation coordinate and coordinate from the laser night-vision device of dynamic(al) correction, as shown in Figure 1, including the guard shield being installed together and The Cloud Terrace, guard shield mainboard PCB it is placed in parallel in described guard shield, main control MCU and connected MENS sensor are installed on described guard shield mainboard PCB, the integrated 3 axle magnetometers of described MENS sensor internal and 3 axle gravity accelerometer, communicated by I2C with main control MCU, and the magnetometer range of 3 axle magnetometers is ± 1.3 to ± 8.1gauss；The gravity accelerometer range of 3 axle gravity accelerometer is ± 2g/ ± 4g/ ± 8g/ ± 16g.
Described guard shield mainboard PCB connects video camera, camera lens, laser instrument, focusing component by interface thereon, the The Cloud Terrace mainboard installed on The Cloud Terrace is connected also by serial ports, installing cradle head control MCU on described The Cloud Terrace mainboard, described cradle head control MCU connects the horizontal step motor of installation, vertical step motor, Horizontal limiting, the most spacing and interface board on The Cloud Terrace.
MENS sensor on described guard shield mainboard PCB must prevent magnetometer disturbed away from devices such as the motor installed on The Cloud Terrace and relays.
When guard shield mainboard PCB is horizontally fixed in guard shield, X-direction is dead ahead；Magnetometer has bigger error with data in gravity accelerometer high speed motions, MENS sensing data only just can be read when MENS sensor is static, after the startup self-inspection of laser night-vision device equipment completes The Cloud Terrace stopping, the data in magnetometer and accelerometer are read in MCU master control in guard shield, the principle of electronic compass is realized further according to MENS sensor, obtaining current The Cloud Terrace level orientation and vertical angle by antitrigonometric function, then the automatic calibration coordinate of equipment shows, is saved in memorizer.When The Cloud Terrace rotates up and down afterwards, the level orientation coordinate calculating real-time update The Cloud Terrace according to the step number of level, vertical step motor shows in picture with vertical angle coordinate, and such staff just can grasp the accurate orientation of laser night-vision device monitoring.Even if having cumulative errors during The Cloud Terrace long-play, coordinate can also be realized from dynamic(al) correction without restarting self-inspection, when the of short duration stopping of The Cloud Terrace, The Cloud Terrace practical level orientation and vertical angle coordinate is obtained by MENS sensor, when displaing coordinate is beyond range of error, at this moment equipment is from dynamic(al) correction displaing coordinate.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
