摘　　要：本文提出一种1553B-to-ZigBee网关的设计,将ZigBee网络作为一个远程终端(Remote Terminal)接到1553B总线控制器上.网关硬件包括1553B接口电路、FPGA、微控制器和ZigBee网络接口电路,1553B总线协议芯片采用BU61585,ZigBee网络接口采用串口RS232;网关软件设计主要是微控制器89S52对1553B接口芯片的初始化和对网络间数据交换的控制.实验验证了1553B-to-ZigBee网关的可行性和有效性.1553B-to-ZigBee bridge is the key to realize the data communication between 1553B bus and ZigBee network.ZigBee network works as a remote terminal controlled by the 1553B bus controller.The bridge hardware and software design are described.The bridge hardware includes the 1553B bus interface,FPGA,processor and the ZigBee network interface.The proposed design uses BU61585 as the 1553B protocol chip and 89S52 as host processor,and the glue logic needed between them is realized on FPGA.The bridge communicates with ZigBee network through serial port RS232 controlled by processor 89S52.It is tested and verified that command and data can be transmitted successfully between 1553B bus and ZigBee network.
