In the daily maintenance of the equipment, a little trick for camera debugging is explored for your reference. Today's road surveillance cameras generally use JvaSANY (Beiting Baitu, etc.) cameras with a strong light suppression function. A standard lens is installed at the front end of the camera, which enables the imaging of the subject to be captured on the target of the CCD image sensor. On the top, there is a gear with a back focus adjustment. When the camera is shipped from the factory, the back focus is properly adjusted. Therefore, after the front lens is fixed, there is usually no need to adjust the camera. In normal use, it may happen that when the lens focus ring is adjusted to the extreme position, the image still cannot be made clear. In this case, the back focus of the camera needs to be adjusted.
The steps for back focus adjustment are as follows:
1. Loosen the fixed screw of the standard lens on the front of the camera, push the lens to telephoto state by adjusting the Zoom In (Zoom In), take a close-up of a distant object, and then adjust the focus (Focu juvenile close-up image adjustment Hao Xi.
2. Perform zoom out (Zoom Out) as opposed to the previous step to pull the lens back to Wide, and the screen becomes a panoramic image containing the close-up objects described above, but no focus adjustments can be made at this time (Note: If this is the case The image is blurred and the focus cannot be adjusted. Instead, it is ready for the next focus adjustment.
3. Rotate the back focus adjustment ring slightly, repeat the adjustment until the screen is clearest, and tighten the front standard lens fixing screw.
At this point, the camera and lens have been debugged.
Tamping rammer:it is made according to the principle of two-stroke internal combustion engine, and there are two pistons in the cylinder, the upper piston is the internal combustion piston, and the lower piston is the buffer piston. The lower part of the cylinder is equipped with a rammer that slopes the bottom surface, so that the vertical axis of the cylinder is skewed forward. The upper piston rod stretches out from the through hole in the middle of the cylinder top cover, and the lower piston rod stretches out from the lower end face of the cylinder, and is integrated with the rammer, and the cylinder and the rammer are tightened by a spring, and a handrail is provided to control the forward direction of the rammer. The fire rammer is under the action of the ignition and explosion force of the combustible mixture, therefore, it jumps off the ground in front of the top and under the action of its own weight, and falls to the ground to ram the soil, and the rammer jumps and falls, and the fuselage moves forward step by step. The rammer product has a wide range of uses, not only suitable for tamping and leveling with various sand, gravel and triple soil, but also suitable for tamping and leveling asphalt gravel, concrete and clay, especially suitable for the construction of buildings, ground, courtyards, roadbeds, bridge piles, trenches, fields, narrow sites and other environments.
