Abstract

The invention discloses POWERLINK and HDLC protocol conversion equipment and a realization method thereof. The protocol conversion equipment comprises: a POWERLINK bus transceiver, a POWERLINK bus protocol controller, a main control unit, an HDLC bus protocol controller and an HDLC bus transceiver. The main control unit comprises: a CPU, a program memory, a configuration memory and a data memory. The CPU uses a NiosII chip of an RISC processor containing 32 bits. In the invention, the advanced 32 bit processor is used to connect with the POWERLINK and HDLC protocol controller and perform an automatic execution analysis and a conversion algorithm to data contents received by the bus. Interconnection communication of POWERLINK real-time Ethernet and the HDLC on-site bus can be realized. The POWERLINK real-time Ethernet and the HDLC on-site bus can be used for one industrial control system.

Description

technical field [0001] The invention relates to a data conversion device in the field of industrial control, in particular to a conversion device of POWERLINK real-time Ethernet protocol and HDLC protocol and a realization method thereof. Background technique [0002] The requirements for locomotive automation and comfort are getting higher and higher, and the amount of on-board data such as train operation control, passenger information system, and multimedia is also increasing rapidly. Traditional field buses such as MVB, CAN, and PROFIBUS are gradually showing defects such as low transmission rate and limited support applications. . Adopting a network with a high-speed transmission rate and a unified standard is the fundamental solution to the problem. Real-time Ethernet has the advantages of high openness, low cost, the lowest transmission rate can reach 10Mbps, and it can be connected to the Internet. It will become the mainstream network of the locomotive control syst...
