现场试验

The key of this task is how could we get the orderliness of train traveling signal. There are some introduction to the analyse ways of train's approaching signal. It emphasizes on the analyse of using syntony demodulation technology to final the long-distance coming train. At the same time, it gives a preliminary analyse in the signal for different cases, takes a research on the identified technology for the coming train, designs and assembles the hardware and software of this system. All of them have got past the test on the spot and got a satisfying result""
