At this moment, the power of the voltage that accumulation descends from the frequency signal that applies if Car antnna (40) near K-Balise (50), then is applied to K-Balise (50) by the frequency signal of constant oscillation frequency resonance.Therefore, can use power free data communications method to guarantee reliability.
If in K-Balise (50) cumulative power, then clock generator (53) uses the frequency signal that applies to produce standard time clock, thereby micro-control unit (52) is by standard time clock and power drive, and (for example by previously stored programming control, 1 bit/3 clock period) reads the data of the terrestrial information of coding in each clock period from memory storage, and output to modulator (51).
At this moment, modulator (51) is modulated the data that receive from micro-control unit (52), and the data of modulation are sent to Car antnna (40).Here, described modulation scheme can be any one in frequency shift keying (FSK), amplitude shift keying (ASK) and the phase shift keying (PSK).
Adopt above modulation scheme, by select with the frequency that is used the safety that can send chunk data and guarantee in active distance, to move according to quantity of information.
If data send to Car antnna (40) from K-Balise (50), the signal process shaping circuit of then modulating is then in demoder (44) demodulation, thereby demodulated data is used to control train.
The data communication of above process keeps fully integrated synchronous between Car antnna (40) and the K-Balise (50), thereby guarantees the accurate data transmission.
In addition, the analytical equipment (55) of K-Balise (50) is analyzed the system performance of K-Basile (50) self, and storage and maintenance logout.
