Does not stop the charge

  In our country's highway charge system, increased gradually using the vehicles automatic diagnosis technology realization charge automation project using the recent years, moreover the electron will not stop the charge technology enhances the road charge efficiency as the government and the enterprise the important method, our country road networking electron charge vehicles recognition already determines in 5. 8GHz frequency band.

  This kind uses the radio signal transmitter-receiver set to distinguish the vehicles the automatic diagnosis technology to origin from Second World War time use airplane target identification system. When this kind of automatic target recognition system from military domain to civil domain shift, experimented and has implemented the many kinds of different vehicles automatic diagnosis technology, and finally chose the radio frequency/microwave recognition technology to take the charge system the vehicles automatic diagnosis technology. So far, the radio frequency technology develops gradually for does not stop the charge system mainstream recognition technology.

  The road charge domain radio frequency recognition technology mainly refers to the work in the microwave frequency band (5. 8GHz) the short distance (8 meters - 30 meters) the communication, in the radio frequency automatic diagnosis system, on international studies and has used the frequency to have three kinds: 915MHz, 2. 45GHz, 5. 8GHz. From has completed does not stop the charge system to look that, the 915MHz system mainly uses in the North America area, the container recognition system, 5. 8GHz system mainly uses in particular European and Asian as well as the Oceanian area, 2. 45GHz system has not formed the mainstream. At present, the electronic charge determination nearby 5. 8GHz the frequency band already is a fact which did not struggle. On the other hand, Europe, Japan, US, China and so on the majority national standard decides in 5. 8GHz to 5. 9GHz frequency band.

  Selects 5. 8GHz frequency band to have following merit: First, the our country communications system standard system approaches the European standard system, the radio frequency resources assignment is approximately same. Next, 5. 8GHz frequency band background noise small, moreover solves this frequency band disturbance and the antijamming question must solve 915MHz, 2. 45GHz is easier than. 5. 8GHz frequency band equipment supplier are once more many, is advantageous to our country ETC system equipment introduction, is advantageous in reduces the system cost, also will be advantageous in the future develops the intelligence transportation system domain other services.
