The speed safety early warning instrument is also called electronic dog. It consists of two parts: hardware system and software system, including radar, GPS positioning, central processing unit and intelligent speed warning system. Use GPS satellite positioning and radar signal retrieval to remind the owner of the presence of speed measuring devices such as electronic eyes or speed radar in advance to prevent fines and deductions for violations such as speeding. Although the function and composition are probably the same, but the performance in the process of use is quite different, today Xiaobian will take you to dismantle the world's first brand of electronic dog, the first version of V1 Chinese version of King Kong, the world's first brand The quality of military industry is explored. Love Saint No.1 V1 originally only had mobile speed measurement, built-in US military radar, without fixed data. After the localization of China, China’s localization was based on the original imported military radar to install fixed data to achieve mobile speed and fixed speed. A function. The mobile speed radar includes a circuit board (analytical radar signal) and a radar waveguide (the speed radar signal is collected and converted into an electrical signal). Next, let's see how the V1 King Kong is the mobile speed measurement. What is the difference with the ordinary electronic dog? General radar Mobile speed warning At present, the manufacturers of production circuit boards are numerous in quality and generally in general. They are generally used by domestic cottages and counterfeit manufacturers. The main brands on the market use the most common imported circuit boards belonging to Korea and Taiwan. The quality is sufficient and the cost is low. The best circuit board is made in the United States, and the V1 King Kong of Love One is the radar of the United States. The radar's main control chip is also regarded as the most important part of the radar in the industry. Its role is to analyze the radar signal and frequency band. The main control chip is completely dependent on imports. Domestic circuit board This chip is also imported, patch production, the effect is general. Love Saint 1 V1 King Kong Radar board and chip as a whole US imports, to ensure overall compatibility. However, protecting upstream companies, like other companies in the industry, erases the label of the main control chip. This is not to deceive consumers and users, but to prevent competitors and manufacturers from breaking the supply chain between upstream and downstream, and destroying the supply chain. So consumers don't have to worry about the impact it has. The general enterprise will carry out the assembly of the radar board and the waveguide. However, because it is the whole imported radar, it is not necessary to reassemble the radar in China. Although the radar performance has been detected in the United States, in order to ensure the radar sensitivity, it is official. It will be tested twice for the local products of the Love St. 1 and will be used after passing the test. Radar detection The radar signal test project needs to be carried out in the shielded room to avoid interference from other signals to the radar. The factory calls this test an oscillating test. The radar feedback waveform is obtained by radar signals from different frequency bands to determine whether the radar meets the qualification requirements. Simply put, the radar needs to respond to the analog speed radar signal. Sealed test environment Radar signal direct illumination test waveform display to determine whether the radar is qualified Sensitivity test Radar signal illumination signal transmitter The radar built into the V1 King Kong of Love One is subject to the above all-round simulation test, and the electronic dog radar is tested in various frequency bands. In the sensitivity test, three frequency bands are used to illuminate the radar. The K frequency is 24.15 GHz, the Ka frequency is 34.30 GHz and the Ka frequency is 35.10 GHz. The three frequency bands also cover different monitoring speed radar signals from high frequency to low frequency.
