Installation and enabling steps of LE-10 lidar
- Use 4 M4 screws (provided by the user according to the thickness of the mounting plate) through a piece of rubber shock pad in the accessories to firmly fix the radar bottom case on the vehicle, action arm or fixed position.
- Insert the three plugs at the end of the aviation cable: the power plug, the special network cable plug, the selection of the alarm area and the alarm plug firmly.
- After the screw connection and electrical connection are confirmed to be correct, the radar can be powered on and preheated for two or three minutes. After the radar is powered on, it will automatically start a circular scan of the surrounding area. (Note that objects such as controlled vehicles and action arms must be immovable before powering on for the first time to avoid accidents)
- Use a personal computer to connect the radar through a network cable or USB cable, start the radar adaptation software, first connect the device in the menu, and then click the "Start" button on the interface, let the computer start to receive the scanning detection data of the radar data port, and check the computer screen. Whether the displayed measured object (shown as a dot on the screen) matches the real object.
- Use the computer to check whether one or several groups of alarm area settings preset in the radar by the manufacturer meet your needs. If not, you can modify the preset alarm area map or create a new drawing. After the drawing is completed, it is recommended that the user set the self-drawing area. Save to new group, do not overwrite factory preset map. After saving the image, select it and then apply it.
- Deliberately put objects into the three warning areas successively, check whether the three warning lights on the front panel of the radar light up successively, and detect whether the corresponding three warning signal lines in the aviation cable are high-level and no objects when there are objects. is low level.
- After the warning signal of the lidar is verified to be normal,the trial can be started. Note that the first movement of the vehicle, action arm, etc. needs to be started in a safe and open environment with manual emergency stop means at all times. Do not run the vehicle and action arm after power-on! Use a personal computer to check the radar scan image for any abnormality before power-on, and confirm that the strong working current and electromagnetic radiation of the vehicle and action arm will not interfere with the radar's work. Then artificially put in the object, let the vehicle and the action arm start to move in the controllable environment, if the movement logic in several common obstacle environments is in line with the intention of use, you can start the field
