Yiwu reversing radar called "three child prodigy." As drivers have their third eye, and now reversing radar is no longer unique to high-end vehicles. With the increase in yiwu city cars and parking spaces become increasingly tense, parking became a big headache for many drivers, and now you to the Yiwu Market, they can for their own car matching a reversing radar. Yiwu, reversing radar encounter obstacles, to issue warning signals, thereby reversing the driver in mind to do a "number" to make reversing easier. At present, Yiwu market, reversing radar, as many as 20 in several brands, prices from three or four hundred yuan to 12 thousand dollars,
Many owners do not know what to compare and choose. In this prompts the user to choose Onccc reversing radar six considerations.
1. Functional
Reversing a more complete functional should have a distance from the radar display, sound alarm, regional alerts and azimuth directions, and some products also have the power on self test function. Currently on the market have emerged with a voice alarm function of the product, this feature gives people the feeling is very direct, but there the main problem is that police lags behind, so that drivers brake late, you are not practical.
2. Performance
Performance, mainly from the detection range, accuracy, stability, and capture target speed display to consider. Detection range, most products ranging from 0.4 ~ 1.5m, a good product can reach 0.35 ~ 2.5m, shown in Figure 2. A wide range of reversing reversing radar can always detected ahead of target, while the excessive pursuit of the minimum detection distance is meaningless, since the actual use must fully consider the inertia factor in vehicle braking. Detection accuracy, mainly depends on two aspects: First, look at display resolution, generic product of 10 cm, while a good product can be up to 1 cm; second is to look at measurement error, which indicates that distance and actual distance between the errors
10cm diameter tubes can be placed in position around 1m to compare, and good products, measurement error should be less than 3cm. Show stability, is not very good reflector in the barrier case, the ability to consistently capture and stabilize the display of the distance between obstacles. Capture target speed, reflecting the radar reversing the ability to capture moving objects. This is to prevent similar children or bicycle from the truck driver suddenly crossed the line of sight is less than the collision caused by an accident is particularly important. In short, reversing radar performance requirements are: measured accurately measured steady, wide range, capture speed.
