Abstract

The invention discloses a CANOPEN-HDLC gateway based on ARM 7. The CANOPEN-HDLC gateway comprises a backboard, a CANOPEN interface board, an HDLC interface board, a main control board, an RS232_USB interface board and a power board providing working voltage for the above boards, wherein the above boards are connected through the backboard. The CANOPEN interface board is responsible for input and output of CANOPEN data. The HDLC board is responsible for input and output of HDLC data. The main control board is responsible for coding and decoding of CANOPEN protocol, coding and decoding of HDLC protocol, protocol function transition, and function and data processing of CANOPEN bus master and HDLC bus master. The gateway in the invention is accord with SO11898, CIADS-301Ver.4.02 and ISO13239-2002 standards. Interface problems among buses of subway and light rail are solved. The gateway provided in the invention has strong versatility and strong reliability.

Description

technical field [0001] The invention relates to CANOPEN and HDLC two kinds of train buses conforming to ISO11898, CIA DS-301 Ver.4.02 and ISO13239-2002 standards. CANOPEN-HDLC is a gateway with both CANOPEN and HDLC communication functions. Switch between two train buses. Widely used in industrial control fields such as subways, light rails and railway locomotives. Background technique [0002] With the rapid development of domestic railways, many advanced foreign technologies have poured into the domestic market. The train communication buses currently used in our country mainly include CANOPEN, HDLC, MVB and WORLDFIP. Only one form of bus exists on a vehicle. This involves a problem. The external interfaces of some products are fixed, so when they are applied to other bus trains, the interfaces are not uniform and cannot be used. Therefore, the CANOPEN-HDLC gateway has become the key equipment necessary for the two bus interfaces, which is of great significance to the...
