I. Introduction to car reversing image
After years of development, the reversing radar
system has upgraded its technology and improved its performance, and has been applied to various models such as trucks, buses, school buses, combine harvesters, corn harvesters, passenger cars, construction machinery and other large vehicles. No matter in terms of structure and appearance, or in terms of performance and price, today’s products all have their own characteristics, and the three most used are digital display, screen display and multi-function rearview mirror display.
This system makes the situation behind the car more intuitive and clear when reversing, which is one of the very practical configurations for reversing safety. When the reverse gear is engaged, the system will automatically turn on the high-definition reversing camera located at the rear of the car, and clearly display the situation behind the vehicle on the reversing LCD screen, allowing you to accurately grasp the road conditions behind, and reversing as freely and confidently as forward.
The reversing camera system allows you to see clearly even at night with infrared light. The anti-magnetic, shock-proof, waterproof and dust-proof performance of professional vehicle-mounted probes has been further improved. The vehicle display adopts TFT true color, which has no signal interference and no stroboscopic after anti-magnetic treatment. It can receive two videos at the same time, and can play VCD and DVD without decoder. At the same time, it has the function of automatic level conversion and automatic switch when reversing. The instrument panel and the interior mirror-type display can clearly display the information behind the vehicle through the on-board camera at the rear of the car. Two reversing rear view cameras can also be installed at the same time, so that there is no blind spot when reversing.
The car reversing image is a series of overall system, which can also be added by the camera device to the car display. Of course, the 360-degree panoramic visual system makes up for the domestic images that can only be provided by radar or a single rear-view camera. The panoramic visual system can have four video outputs, namely front, rear, left and right. Install cameras in the front, rear, and under the rear-view mirrors of the car. It is controlled by remote control and can automatically switch the screen. The video can be composed of four videos or a single video. Increase the anti-theft monitoring and driving safety of driving.
2. Comparison of reversing image and radar
Advantages and disadvantages
1. The advantages of reversing image compared with reversing radar are:
The installation is simple. Generally, the normal single output reversing image only needs to connect the positive pole of the power link cable to the positive pole of the car reversing light power supply, and the negative pole of the power link cable to the negative pole of the reversing lamp or ground (GND). According to the different models, you can understand how to arrange the cable by simply researching. The camera can be installed by opening the hole in an easy-to-install position. At a glance, after the vehicle is in reverse gear, the physical scene at the rear of the vehicle can be clearly seen, which is convenient for the driver to judge.
2. Compared with the reversing radar, the disadvantages of the reversing image are:
Active, the reversing image requires the driver to observe the dynamics in the display screen first when reversing. The premise is that you need to go to You can only understand the situation by looking, but the reversing radar can make a sound reminder when you observe the left side and if there is an obstacle on the right side that is closer to the car. Such as: ‘Danger on the left, etc.’.
Suggestions for use
If you prefer beautiful and simple installation, you can install a reversing camera;
If you are used to observing Rearview mirror, and want to have a sound to remind the auxiliary group to park, then choose the reversing radar;
If you think you need double installation protection, if you need both video and sound functions, then choose to install visual Reversing radar is enough;
Notes on classification
When choosing a reversing image, you should pay attention to whether it matches your car model, which can be determined from the camera model, power supply Voltage, screen size, waterproof, anti-vibration, anti-interference, etc.
First of all, if it is used in a car, we can consider the camera model (whether waterproof and night vision can be selected), screen size (3, 5, 7 inches), power supply voltage (12V), truck , passenger cars and other large vehicles are 24V, you can.
Secondly, if it is a large car, the choice should be careful. First, there is a big gap between the working conditions of large vehicles and sedans. For example, the driving environment of the construction road is bad, the temperature is bad, the reverse gear is frequently used, and the working time is long. Second, the general power supply voltage of large cars is 24V, so the reversing image of the car cannot be used. Therefore, when we choose products, we must pay attention to only choosing the right products, rather than price or other factors to determine the choice of products.
Reversing image application
Now the reversing image is no longer a patent for mid-to-high-end cars, and some small cars and micro-customers have also been equipped with reversing images The system, such as the high-end Weike Junfeng CV03, is the first model among the Weikes to be equipped with a reversing image, which also allows more commercial consumers to experience the convenience brought by technology configuration for reversing into a parking space.
