How to install the laser on the radiation switch

Laser-to-shoot detector switch We also call it laser-on-beam, the problems that need to be paid attention to during the installation process and the overall installation process. We will use the laser-observer detector of the passenger-European security as a sample to explain in detail.

There are three types of laser detectors installed in Europe. They can be installed on the ground or on a solid mounting platform and on the top of the wall. If installed on the ground, please pre-embed the expansion bolt with a diameter of 10mm or the bolt on site according to the size of the base of the equipment. When fixing and fixing, you can use the level as an auxiliary tool to keep the detector horizontal and vertical as much as possible. When the detector is planned to be installed on the outside of the fence or guardrail, please make the mounting bracket according to the hole size of the detector base. The strength of the mounting bracket must be Make sure that the detector does not deform or shake during long-term work outdoors. (The base or wall of the laser detector must be installed with sufficient strength to ensure that the detector does not sway when subjected to strong winds. The installation is arranged in the order of transmission-reception/reception-emission at 90°. Only one transmitter and one receiver can be installed at the corner, or two transmitters can not be installed at the 90° corner. These are the tasks that need attention and preparation for laser detector installation.

After the preparation is completed, the laser beam detector transmitter/receiver face-to-face pairing must be fixed in accordance with the selected position of the engineering design. After the detector is fixed, the device can be connected. The red line of the transmitting end and the receiving end is connected to the DC12V positive pole, the black line is connected to the DC12V negative pole, and the green and blue lines of the receiving end are normally closed switching signal outputs (regardless of positive and negative), connected to the alarm host zone input terminal or the bus address module normally closed. Input.

It should be noted that since the spot of the laser beam is small and the laser of 808 nm is an invisible laser, it is recommended that the user choose to perform at night during the alignment adjustment, although the 808 nm laser is invisible, but in a dark environment, Within a certain distance, when the laser illuminates the surface of a relatively smooth object, especially the surface of a white object, the human eye can still see the red spot. Using this characteristic of the 808nm laser, when the detector is installed, debugged or tested, The efficiency of debug alignment can be improved with some aids.

The above is a detailed explanation of the installation steps of the laser beam, then what should we do in the debugging after the installation is successful? Tools to be prepared before laser debugging: Φ3 one-word screwdriver, one Φ4 Phillips screwdriver, one brown box of ordinary packing box, equipment for observing laser ray: driving recorder / laptop with camera function / infrared The camera and the monitor and power supply that can be used with the infrared camera, the on-site debugging needs 2-3 people to cooperate at the same time, and the commissioning should carry the walkie-talkie or mobile phone with the on-site contact.

The debugging should be selected to energize the laser transmitter and the laser receiver when the sky is dark or the ambient light is dim. After the laser transmitter is powered on, the laser emission window has a red laser beam on the side of the emission window of the laser transmitter; the laser receiver is powered After that, if the receiver does not receive the laser signal from the laser transmitter, the blue alarm indicator of the laser receiver lights up; the tester holds the white cardboard one by one from 5-10 meters on one end of the laser transmitter, and the other uses The laptop's camera (or an ordinary analog camera with infrared vision) looks at the white laser spot on the cardboard. When the laser light from the laser transmitter is projected onto the white cardboard or carton, the tester can see the bright white strip laser beam on the laptop or the display connected to the infrared camera through the camera; a white spot is a Laser beam. The tester informed the technician at the transmitter to adjust the X-axis (horizontal) and Y-axis (vertical) of the corresponding beam by observing the laser beam on the whiteboard; when the laser beam on the cardboard was observed to deviate significantly from the transmitter A straight line with the receiver informs the transmitter to adjust the X-axis (horizontal) adjustment screw of the corresponding beam for left and right adjustment; if the laser beam observed by the tester on the cardboard is significantly higher or lower than the receiver, please inform The transmitter side adjusts the Y-axis (up and down) adjustment of the corresponding beam, and adjusts the laser beam emitted by the transmitter to be in line with the receiver while keeping the height of the laser beam exactly the same as the height of the receiver ( The farther the detection distance is, the longer the 808 nm laser beam will become, and the laser beam will cover each other at a certain distance, which is normal.

After all the beams are properly aligned, the receiver's alarm indicator is off, and the beam blocking test can be performed. The tester quickly passes through the middle of the transmitter and receiver, and the blue indicator on the receiving end lights up. At the same time, the relay changes from normally closed to open.

After all of the above is completed, it is already installed and debugged.
