A navigator electronic dog allocation machine was launched on the field. This all -in -one machine can fully meet the owners needs.But in the face of this new product, many car owners do not know what the advantages of the navigator electronic dog all -in -one machine? So today, I will introduce the knowledge of navigation instrument electronic dogs.
Radar electronic dog navigator selection skills
1. Choose the brand ---- quality and after-sale that the GPS that guarantees the GPS market is full of GPS market, so that consumers do not know how to choose, especially the appearance of miscellaneous brands and cottage products.Friends of the products are deeply touched. Not only are the quality not guaranteed, but it is not guaranteed in terms of service. Once a problem occurs, it can only be dumb.Big brands are the most assured choices. From the quality of the product to the brands service, users can guarantee it. Once there is a problem, it can be solved for you.Although the price is more expensive, the brand has spent a lot of manpower, material, energy, and financial resources in all aspects such as R & D, production, service, and marketing.There are noble truths.
2. Select GPS through the quality inspection of the national authoritative institutions not only depends on the brand, appearance, and functions, but also pay attention to its hardware quality.It is difficult to guarantee in LCD screen, GPS chip, motherboard, processor, etc., and the quality of this machine can be seen.The hardware configuration of the brand GPS is more formal, and it must pass the ISO quality production standards (mainly ISO2000 quality certification, ISO14001 environmental certification) and other certifications.Therefore, the quality of the accessories they use can be guaranteed, which improves the overall quality of the product.
3. Whether to adopt mature plans and miscellaneous cards and cottage GPS are cheap because they adopt a low price scheme. This scheme performance machine is unstable and prone to quality problems.Buying products with stable performance can ensure quality. Consumers who buy this product can use it with confidence.
4. Functional configuration: Product functions are one aspects that riders value very much. With the development of GPS, various entertainment functions have been implanted in products, such as digital TV, MP3, MP4, MP5, e -books, games, etc.EssenceIn terms of practical functions, such as navigation, fixed speed measurement, flow speed measurement, real -time road conditions, Bluetooth, FM launch, reversing vision, stock securities, stock securities, etc. are also very important.Consumers must consider their own needs when buying GPS. Although the miscellaneous cards and cottage GPS can be implanted in these functions, due to the inferiority of hardware and backward solutions, it will greatly affect the function of the function, such as searching for Xingxing, such as XingxingSlow, inaccurate positioning, inaccurate speed measurement, poor TV signals, and so on.
5. After -sales service and map upgrade: Electronic products will inevitably fail, and after -sales service is very important. Large brands have an excellent after -sales service system. Once problems occur, you can solve it.As soon as the after -sales service said, the riders could not be resolved once a problem occurred.Consumers should choose navigation maps with simple operation, convenient use, and complete data when buying GPS.
How to avoid using the speed radar electronic dog to avoid running through the red light
1. I installed it. Why did I not be warned by the red light when I was taken in the red light? In fact, the camera driver at the camera at the intersection can be achieved through many technologies.Under normal circumstances, you can trigger photos through radar triggers, or induced coils, or trigger photos by image recognition.When using a radar trigger, when the popular light is on, a radar area is formed before the parking line, and the electronic shutter photo is activated when a car passes.At this time, it is possible to work.When using inductive coils to trigger photos, when construction is under road construction, inductive coils are buried under the road. When there is a car running a red light, the induction coil starts electronic shutter to take pictures.When using image recognition technology, the ground white line is used as the warning area. When there is a car through the red light, the white line on the ground is blocked and triggered the photo.
2. Is the sensitivity of the radar speed detector, the better? Generally speaking, the higher the sensitivity of the radar speed detector, the better, but in addition to the indicators of the radar speed detectorReport rate.Because there are many electrical signals around us, as the sensitivity increases, the rate of misunderstanding will increase.It is okay to exercise simply on the highway. Once you enter the city, you are like a soldier. Therefore, the higher the sensitivity, the better. As long as you can provide sufficient early warning distance, according to the actual use status, the range of 100-400 meters can meet the use of use.It requires that slowing from 100 kilometers per hour to 0 usually requires about 60 meters, and there is no need to decelerate to 0 during deceleration. It is enough to slow down to normal levels for 2 or 3 seconds.Fixed speed measurement equipment will continue to produce radio waves when used. However, due to the requirements of the camera and avoiding misunderstanding, the radar trigger area distance will be very close, usually about 30 meters, but it does not meanDue to the reflection of the ground, the speed detector will receive a radio wave at a farther distance and issue alarm.For hand -holding radar does not continue to produce detective radio waves, only the detection radio waves are generated when holding the button, but the handheld radar uses a fuzzy aiming, so it takes more time.In addition, the detector received the radio wave first, and then the radar received the radio waves returned from the reflection and started to calculate the speed. However, the speed radar needs to receive 8 continuous reflection signals to calculate the speed.Speed ??can avoid tickets.
Precautions for buying electronic dogs
In terms of specific performance parameters, car electronic products that choose GPS navigation functions are the most important thing to look at the accuracy, receiving ability, satellite trajectory, and parallel channels of GPS navigation.The accuracy of positioning is generally normal within 5-10 meters. If it exceeds dozens of meters, such electronic dogs can be abandoned.GPS navigation can generally calculate the geographical coordinate position of the receiver when receiving 3 or more satellites.The satellite trajectory refers to the 24 satellites on the earth, each with each satellite in a group, running around the earth along the 6 tracks.
