| Abstract: | This paper introduced the networking problem of indigenous BCU for CRH2 EMUs and analyzed the communication mode between terminator and BCU.A communication gateway for indigenous BCU was designed and protocol conversion was achieved between terminator(HDLC) and BCU(RS485).The experiment which is based on import test bench verifies the integral function of the communication gateway. |
