Hello everyone, I am Wang Lei, who runs a car modification shop in Nanjing. In the past year, more and more riders have purchased electronic dog products. But there are many electronic dog brands on the market, and most of the riders don't know how to buy electronic dogs. There are also some riders who have purchased the cottage electronic dog brand due to lack of experience.
Because I am running a car modification shop in Nanjing, I often help car owners buy and install electronic dogs, so I know about the various electronic dog brands.
Analysis: How does the electronic dog work?
To know how to buy an electronic dog, you first need to understand how the electronic dog works. Below, let me introduce the working principle of the electronic dog, I hope to help the owners to buy the electronic dog brand. There are two main ways in which electronic dogs work: one is a fixed speed warning, and the other is a mobile speed warning. In addition, high-end electronic dogs also have the ability to tail.
First, the "fixed speed measurement" of the electronic dog principle
In advance, the staff will bring the GPS positioning machine to collect the coordinate points of the fixed electronic eye nationwide, and then make the electronic dog data and input it into the electronic dog machine. The electronic dog itself has a GPS positioning chip that can calculate the speed and direction of travel of the car. Alerts are issued in advance when the vehicle travels to a fixed point. If you speed, the electronic dog will broadcast a voice "You have already speeded."
The fixed warning speed warning of the electronic dog can prompt the fixed red light electronic eye in front, the fixed speed electronic eye, the illegal photography electronic eye, and the fixed monitoring electronic eye. To determine whether the fixed speed measurement of the electronic dog is accurate, the most important thing is to look at the electronic dog data. Regarding the electronic dog data, pay attention to the following questions when purchasing.
Question 1, is the electronic dog data comprehensive?
At present, the best electronic dog data made in China is the DSA data, Kay LiDE and Gao De. Car owners need to pay attention to the fact that the domestic electronic dog brand is very numerous, but many small manufacturers do not have the ability to collect fixed electronic eye data across the country. These small manufacturers will use the cracked version of the big brand in order to save costs. However, this cracked version of the data is often not comprehensive, and the cracked version of the data upgrade is very troublesome.
Question 2, is it convenient to upgrade the electronic dog data?
It is very common to re-plan and construct traffic roads across the country or to rebuild new roads. This requires electronic dog data to be constantly upgraded. Some big brands of electronic dog data can be updated once a week. But if you buy a cottage electronic dog, it is very troublesome to update the electronic dog data.
Question 3, about "Cloud Electronic Dog"
Cloud electronic dog has appeared in the last two years, can achieve electronic dog data update, the first time to update the latest data to the electronic dog. When upgrading, it takes 1-2 minutes. If you buy a cloud electronic dog, there will be a SIM flow card in the package. Generally, this SIM card is free of charge for three years.
