What is a car computer? Detailed on-board computer installation steps
With the development of modern electronic technology, more and more cars are now equipped with a car computer , but many friends do not understand it, then what is a car computer? How to install it yourself? The following decoration home decoration network small series will bring you detailed car computer installation steps, I hope to help everyone.
What is a car computer?
The on-board computer is a special vehicle information product developed with special anti-high temperature, anti-dust and anti-seismic functions and can be integrated with automotive electronic circuits. It is a highly integrated vehicle multimedia entertainment information. center.
What is the function of the car computer?
The on-board computer can realize all the functions of home computers, support in-car Internet access, audio-visual entertainment, satellite positioning, voice navigation, games, telephone and other functions, as well as visual reversing, fault detection and other specific functions. Its main functions include in-vehicle all-round multimedia entertainment, GPS satellite navigation, professional diagnosis of automotive information and faults, and mobility for office and industrial applications. At present, only the top models such as BMW and Audi in foreign countries are equipped with similar intelligent in-vehicle systems.
Detailed on-board computer installation steps:
Installation Step 1. Disassemble the original central control playback device:
In order to fix the liquid crystal display, whether it is an integrated chassis or a split chassis, we must first remove the original central control playback device on the central control panel to free up the installation space of the onboard computer. The LCD monitor and the original playback device must have the same length, width and height. Even the screw position must be the same, otherwise it cannot be fixed in the original position. When purchasing this product from the merchant, this parameter must communicate with the merchant clearly, tell the merchant your specific model, whether the original central control panel has been modified, etc., so that the merchant will make a suitable LCD display casing according to your central control panel slot. . Be careful when removing the original central control playback device. Many central control panel fixings are used in addition to the use of screws. After removing all the screws, if the panel is still unable to be removed, check whether the buckle is removed.
Installation step 2, selected chassis placement:
After removing the original central control playback device, do not rush to install the display. Next, you must select the host installation location of the onboard computer. If you are using an integrated onboard computer, you can skip this step. There are two main places for the mainframe installation of the split-type on-board computer, one is under the front seat and the other is the trunk. The host is placed in the trunk, which requires a long cable to be laid, which is easy to cause signal attenuation and affect the use of the on-board computer. Therefore, the author places the host's position under the passenger seat. When laying the cable under the passenger seat, you can directly route from the central control panel to the lower end of the armrest box, and then from the lower end of the armrest box to the passenger seat, the entire dark line is laid, which will not affect the interior. After selecting the installation location of the host, you can install the host. I fixed the main unit directly to the carpet under the seat. However, before the main unit is fixed, the position to be placed is actually measured, so that the passengers on the passenger seat and in the rear seat move their feet to see if they will kick the host. In addition, when installing the main unit, connect the cable on the rear panel of the main board to the armrest box, so that the passenger's feet will not kick the cable, causing the cable to loosen. Since the bottom of the mainframe is completely attached to the carpet, which is not conducive to heat dissipation, a rubber pad of a certain height can be placed on the four corners of the bottom of the chassis, so that a certain amount of heat dissipation space can be left at the bottom of the chassis.
Installation step 3, laying cables and wiring methods:
Before laying out, you should review all the interfaces of the chassis, select several interfaces to be used, and then fix the prepared ones in succession. The connection function of the on-board computer is almost the same as that of the home computer. The difference is that because of the space, many connections need to be transferred in the chassis, so be sure to understand before assembling.
Installation step 4, installation of visual reversing camera:
The visual reversing camera is 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 liquid crystal display , and the wired camera has an extra wiring work. The power cord is more troublesome. Since the reversing camera needs the reversing light to supply power, you need to find the reversing lamp power cord in the vehicle manual, then connect the camera power supply and the reversing light in parallel. Pay attention to the polarity of the power supply and be sure to connect it correctly. Otherwise it is easy to burn out the camera.
The AV interface of the liquid crystal display generally has an active recognition display function. As long as the camera transmits the signal, the display will give priority to the display. Therefore, when the vehicle is in reverse gear, the camera turns on the backup lamp power supply, and the liquid crystal display will shield the computer VGA signal, giving priority to the reverse display. image.
Installation step 5, internal restoration work after installation:
Next, internal power recovery can be performed after the power-on test. At this point, you should start the car to see if the vehicle's automatic power control system delays starting the computer, and then check whether the computer functions are normal. Once the test is complete, the panel can be restored. The recovery of the panel is relatively easy, just remember not to miss the screws.
