Before and during the operation of the vehicle, the cloud track will conduct self-diagnosis and complete more than 300 tests including the whole system. It can also work normally at extreme temperatures, and can adapt to the low temperature of MINUS 40℃ and the high temperature of 80℃. For passengers, you can brush your face and enter the station, or you can connect to high-speed wireless broadband. According to BYD, cloud track unmanned driving not only adopts BYD's own control technology and positioning technology, but also integrates Huawei's eLTE communication technology, namely the 4.5G rail transit wireless private network.
The 4.5G rail transit wireless private network applied in the cloud rail unmanned driving system has three main characteristics: First, it realizes the comprehensive bearing of a network, so that all kinds of information such as data, voice and video carried by multiple networks in the past can be transmitted and stored in one network; Secondly, the scheme has the advantages of high reliability and strong anti-interference, high-speed seamless switching of signals and quick response of instructions, which makes the cloud track operation more reliable. Thirdly, adhering to the principle of open cooperation, we have made deep adaptation with various applications and industry terminal manufacturers of BYD Cloud Track, creating a new ecology of multi-win situation.
