DETAILED DESCRIPTION

[0015] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0016] like Figure 1-4 As shown, a new type of laser spot monitor in this embodiment includes a shell 8, which is made of 5 aluminum plates (excluding the control panel) spliced ​​together. The aluminum plates are independent of each other, and changing one of them will not affect the whole machine, thereby improving the subsequent secondary function expansibility.

[0017] like Figure 4 As shown, a control panel is installed on one side of the shell 8, and a display 9 is arranged on the control panel. A main switch 10, a laser switch 11, a storage switch 12, and a power indicator light 13 are arranged on one side of the display 9, and a PAL video interface 14, an SDI video interface 15, a DC 12V power output 16, and a DC 24V power output / input 17 are arranged on the other side of the display 9. It is fully functional and has friendly human-computer interaction.

[0018] like Figure 1 ,3 As shown, a laser detection component, a television component, a video storage component, and a battery 4 are installed in the housing 8. The laser detection component includes a laser lens component 1 and a laser information processor 2. The laser lens component 1 is installed at one end of the housing 8, and the laser information processor 2 is located at the rear end of the laser lens component 1; the laser lens component 1 converges the laser signal reflected by the target on the four-quadrant laser detector, and then outputs four pulse voltage signals. The laser information processor 2 performs low-noise secondary amplification, high-pass filtering and other conditioning on the pulse voltage signal output by the laser lens component 1, and then implements sampling, digital filtering, and automatic gain control to complete the target deviation angle and echo energy solution.

[0019] The TV assembly includes a TV lens 7 and a TV core 6. The TV lens 7 is installed at one end of the housing 8 and is located on the same side as the laser lens component 1. The TV core 6 is installed at the rear end of the TV lens 7. The TV lens 7 is used to converge the laser signal reflected by the target. The TV lens 7 is equipped with a 1064nm wavelength filter to weaken the background and highlight the laser spot characteristics, and a 12-120mm continuous zoom lens is used to achieve a 50m-5000m range. The TV core 6 uses an ultra-low illumination high-definition SONY IMX385 detector, which can receive the laser signal converged by the TV lens 7 for clear spot imaging, and then output one analog PAL video and one digital SDI video.

[0020] The video storage component includes a video memory 3 and a video converter 5. The video memory 3 is installed at the rear end of the laser information processor 2 and the TV movement 6, and the video converter 5 is installed at the rear end of the video memory 3. The video converter 5 mainly converts the digital SDI video output by the TV component into an HDMI video, and then inputs it into the video memory 3 for HDMI video storage. The video memory 3 simultaneously outputs one HDMI video for display. When storing, the U disk is directly inserted into the USB port of the shell, which is very convenient to use.

[0021] A battery 4 is installed in the housing 8 on one side of the video memory 3. The battery adopts a large-capacity rechargeable lithium-ion battery of 22400mAh, which is divided into three independent outputs of DC24V / 3A, DC12V / 3A, and DC5V / 2.4A to power other electrical components and achieve a steady-state endurance of more than 3 hours.

[0022] Working principle:

[0023] Press the main switch 10 to start the power output of the battery 4, output DC5V to power the video memory 3, output DC12V to power the video converter 5, the TV core 6, and the display 9, and the power of the battery 4 is displayed on the power indicator 13. When the battery is fully charged, all four indicators are lit;

[0024] Press the laser switch 11 to start the battery 4 to output DC24V to power the laser information processor 2 and the laser lens component 1. The laser information processor 2 performs low-noise secondary amplification, high-pass filtering and other conditioning on the pulse voltage signal output by the laser lens component 1, and then implements sampling, digital filtering, and automatic gain control to complete the target deviation angle and echo energy calculation, and then outputs the RS422 digital signal through the DB9 female connector on the housing 8.

[0025] The TV core 6 outputs a digital SDI video to the video converter 5, and the video converter 5 converts it into a digital HDMI video and gives it to the video memory 3. Pressing the storage switch 12 starts the video memory 3 for video storage, and pressing it again stops storage. When storing, directly insert the U disk into the USB port of the shell 8; the video memory 3 outputs a digital HDMI video to the display 9 for display.
