Description

Technical Field

[0001] This utility model relates to the field of instruments and equipment, and in particular to a long-range laser rangefinder and positioning instrument. Background Technology

[0002] There is a need to locate remote targets in both civilian and military fields. Positioning methods include radar, UAV flight surveying, and electronic maps. Among these, radar positioning is relatively complex and the equipment cost is relatively high, which limits its use in some civilian situations. If UAVs are used to fly directly to the target point to measure the location, they are also limited by environmental, airspace, endurance, and license conditions. Using high-precision electronic maps to locate remote coordinates is suitable for situations with clear and fixed landmarks. If the target features are not obvious (such as grasslands, deep mountains, etc.) or the target appears temporarily, it is difficult to determine the target by human observation, and the deviation is also large. Therefore, a long-range laser rangefinder and locator with good stability and simple operation is needed. Utility Model Content

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A long-range laser rangefinder positioning device comprises: an instrument housing 21, buttons 2, a display screen 6, a TYPE-C port 12, a battery 15, a laser rangefinder module 16, a gun sight telescope 17, a motherboard 18, an electronic compass module 19, and a pitch angle module 20. The laser rangefinder module 16 and the gun sight telescope 17 are mounted parallel to each other on the base plate 14 of the instrument housing 21. The laser emitting lens 9 and the laser receiving lens 10 of the laser rangefinder module 16 are located on the same side of the instrument housing 21 as the objective lens 8 of the gun sight telescope 17. The laser emitting lens 9 is exposed through the rear panel 11 of the instrument housing 21. The rear panel 11 also houses the TYPE-C port 12, the electronic compass module 19, and the pitch angle module 20. Group 20 is installed on the base plate 14 on the left side of the gun sight telescope 17; battery 15 is installed on the base plate 14 on the left side of the laser rangefinder module 16; main board 18 and display screen 6 are installed on the front panel 4 of the instrument housing, on the same side as the eyepiece 7 of the gun sight telescope 17; the base plate 14, front panel 4, rear panel 11 and U-shaped plate 3 are fastened together by screws to form the instrument housing 21. The top of the U-shaped plate 3 is equipped with button 2 and Beidou antenna 5. A handle 1 is installed on each side of the U-shaped plate 3. The base plate 14 of the instrument housing is equipped with a dovetail groove 13 structure for connecting with other supports to achieve fixed measurement and improve stability. The gun sight telescope 17 has a built-in crosshair, which can be used to aim at the target.

[0030] The instrument housing 21 is composed of a base plate 14, a front panel 4, a rear panel 11, and a U-shaped plate 3, all fastened together with screws. It features a compact structure and good sealing. The laser emission lens 9 is only exposed through the rear panel 11. The electronic compass 19 and the pitch module 20 are both built into the base plate 14, preventing direct wear and tear on core components from mud and rainwater in the field. This design is more resistant to environmental corrosion than existing technologies where exposed sensors are easily damaged. Furthermore, the handle 1 of the U-shaped plate 3 is not only easy to carry but also provides a "two-handed grip fulcrum" in the field, reducing shaking when holding with one hand. When the dovetail groove 13 is connected to the support, it can withstand strong winds through the support's counterweight, ensuring strong stability. The dovetail groove 13 of the instrument housing base plate 14 can be connected to the support for fixed measurement, improving stability in windy and vibrating environments. The handles 1 on both sides of the U-shaped plate 3 support handheld portability, making it suitable for both fixed monitoring scenarios in border defense and forestry and mobile measurement needs in field exploration. The laser rangefinder module 16 is installed in parallel with the gun sight telescope 17. The laser lens and the gun sight objective lens 8 are exposed on the same side. Aiming and ranging are performed synchronously. It is not affected by the "weak signal failure" of electronic maps. It can still work normally in complex electromagnetic environments or areas without signals. The structure is anti-interference. Example

[0031] An electrical schematic diagram of a long-range laser rangefinder positioning instrument, wherein the laser ranging module 16 is: Figure 8The laser ranging module 16 consists of a laser emitting lens 9, a laser receiving lens 10, and a ranging control board 22. The laser emitting lens 9 and the laser receiving lens 10 are respectively connected to the ranging control board 22. The ranging control board 22 is connected to the main board 18 through four control lines, two of which are power lines and the other two are communication lines, which transmit data to the main board 18 through terminal P9. The main board 18 can control the power supply of the laser ranging module 16 and control the laser ranging module 16 to complete distance measurement.

[0032] The electrical schematic diagram of the laser ranging module 16 is as follows: Figure 8 The laser ranging module 16 includes a laser emitting lens 9, a laser receiving lens 10, a laser emission driver, a laser thermal control circuit, a laser receiving APD circuit, a laser receiving signal shaping and amplification circuit, and a laser receiving signal pulse timing circuit. The main controller of the laser ranging module drives the laser to emit a laser pulse from the laser emitting lens 9. The laser pulse is reflected back from the target object and converged to the APD circuit through the laser receiving lens 10. The APD circuit converts the laser signal into an electrical signal, and then calculates the laser transmission and reception time through shaping, amplification, and pulse timing. Based on the laser's flight time, the main controller obtains the distance from the instrument to the target object. This distance data is transmitted to the main board 18 through terminal P9. Example

[0033] The electrical schematic diagram of the electronic compass module 19 in a long-range laser rangefinder positioning instrument is as follows: Figure 7 The electronic compass module 19 uses a microcontroller U8 and a geomagnetic sensor U9 to realize the electronic compass function. The geomagnetic sensor U9 is a three-axis sensor, which is connected to pins 32 and 33 of the microcontroller U8 via the IIC bus. The microcontroller U8 obtains the three-axis magnetic field data at a data acquisition rate of 200Hz, which is sufficient for handheld measurement. The raw data of the three-axis magnetic field can be converted into azimuth data through calibration and adjustment within the microcontroller. The azimuth data is transmitted to the motherboard via terminal P8. Example

[0034] The electrical schematic diagram of the pitch angle module 20 in a long-range laser rangefinder positioning instrument is as follows: Figure 9 The pitch angle module 20 uses a microcontroller U10 and an accelerometer U11 to realize the pitch angle measurement function. The accelerometer U11 is a two-axis accelerometer. The accelerometer U11 is connected to the microcontroller U10 and can measure acceleration data within ±90 degrees in the pitch direction. The acceleration data refresh rate can reach 1MHz. The microcontroller U10 processes the acceleration data into angle data, and the angle data is transmitted to the motherboard through terminal P7.

[0036] The battery 15 is connected to the motherboard terminal P1, which in turn connects to the power management chip U4. The power management chip U4 converts the battery voltage into two power supplies: one supply powers the laser ranging module 16, and the other supplies the ARM main processor U1 and other circuits. The button 2 on the top of the instrument is connected to the motherboard terminal P2, which in turn connects to pin 2 of the ARM main processor U1. This button controls the instrument's power on / off and measurement. The real-time clock U2 and the storage chip U3 are connected to pins 45, 46, 42, and 43 of the ARM main processor U1 via IIC interfaces, respectively. The system includes: a data storage and real-time clock; a display U5 connected to pins 25, 26, 27, and 28 of the ARM main processor U1 via an SPI interface for LCD display; a Beidou module U6 connected to pins 15, 16, 17, and 18 of the ARM main processor U1 via an SPI interface for Beidou positioning, with its S1 interface connected to the Beidou antenna 5 on the top of the instrument housing; and a Bluetooth module U7 connected to pins 39 and 40 of the ARM main processor U1 via a UART3 interface for external Bluetooth communication. Pins 30 and 31 of the ARM main processor U1 are UART0 interfaces, connected to terminal P3 on the motherboard, and externally connected to the laser ranging module 16 to control the laser ranging module to complete the ranging. Pins 5 and 6 of the ARM main processor U1 are UART1 interfaces, connected to terminal P4 on the motherboard, and externally connected to the electronic compass module 19 to realize azimuth angle measurement. Pins 13 and 14 of the ARM main processor U1 are UART2 interfaces, connected to terminal P5 on the motherboard, and externally connected to the pitch angle module 20 to realize the instrument pitch angle measurement.
