In order to fix the LCD monitor, the original central control playback equipment on the central control panel must be removed to make room for the installation of the vehicle-mounted computer, whether it is an integrated chassis or a split chassis. The length, width and height parameters of the LCD and the original playback equipment should be consistent, even the screw position should be consistent, otherwise it will not be fixed in the original position. This parameter should be clearly communicated with the merchant when purchasing products from the merchant, telling the merchant your specific model and whether the original central control panel has been modified. , so that merchants can make suitable LCD cases according to your central control panel slot. Be careful when removing the original central control playback equipment. The central control panel of many vehicles is fixed with screws. If the panel cannot be removed after all the screws are removed, it is necessary to check whether the buckle has been removed.
Installation Step 2: Select the location of the chassis:
Don't install the monitor in a hurry after removing the original central control playback equipment. Next, select the host installation location of the vehicle-mounted computer. You can skip this step if you use an all-in-one car computer. There are two main installation positions of the main engine of the split vehicle-mounted computer, one is under the front seat and the other is the trunk. The main engine is placed in the trunk, so it needs to lay a long cable, which is easy to cause signal attenuation and affect the use effect of the on-board computer. Therefore, the author chooses the position of the main engine below the passenger seat. When laying cables under the passenger seat, the cables can be directly laid from the central control panel to the lower end of the armrest box, and then connected to the passenger seat from the lower end of the armrest box. The whole cable laying process will not affect the interior decoration. After selecting the installation location of the host, you can install the host. The author fixed the mainframe directly on the carpet under the seat. But before fixing the main engine, it is necessary to measure the position and let the passengers in the co-pilot seat and the back seat move their feet to see if they can kick the main engine. In addition, when installing the mainframe, the connection place between the cable and the rear panel of the motherboard should face the armrest box, so that passengers' feet will not kick the cable and cause the cable to loosen. Because the bottom of the main engine is completely attached to the carpet, which is not conducive to heat dissipation, rubber pads with a certain height can be put on the four corners of the bottom of the chassis, which can leave a certain heat dissipation space for the bottom of the chassis.
Installation step 3: Cable laying and wiring method:
Before laying, check all the interfaces of the chassis, select several interfaces to be used, and then fix the prepared interfaces on them continuously. The connection function of the car-mounted computer is basically the same as that of the home computer, but the difference is that many connections need to be transferred in the chassis for space reasons, so you must understand them before assembly.
Installation Step 4: Install the visual reversing camera:
Visual reversing cameras can be divided into wired and wireless. The installation of the signal line is relatively simple, as long as the output port of the camera is connected to the AV interface of the LCD, and the wired camera has another wiring job. The power cord is troublesome. Because the reversing camera needs the power supply of the reversing lamp, it is necessary to find the power supply line of the reversing lamp in the vehicle manual, and then connect the camera power supply and the reversing lamp in parallel. Pay attention to the polarity of the power supply, and be sure to connect it correctly, otherwise it will easily burn the camera.
Generally, the AV interface of LCD has its own active recognition and display function, so as long as the signal from the camera will be displayed first, so when the vehicle is in reverse gear, when the camera is connected to the power supply of the reversing lamp, the LCD will block the VGA signal of the computer and display the reversing image first.
Step 5: Internal recovery after installation:
Next, after the power-on test, internal recovery can be performed. At this point, you should start the car, check whether the automatic power control system of the car delays starting the computer, and then check whether the functions of the computer are normal. After the test is completed, the panel can be restored. It's easy to recycle the panel, just remember not to miss the screws.
