Problems solved by technology

[0004] However, since different transmission media cannot communicate directly, and the communication protocols between different manufacturers are not compatible, special gateway equipment and complex protocol conversion software are required to Realize the interconnection of different networks
Although there are already some single-protocol conversion gateways, such as ISA100. Form a large intelligent factory network

Embodiment 1

[0058] A gateway for Powerlink and 6LoWPAN. Such as figure 1 As shown, the gateway includes Powerlink bus transceiver 1, Internet bus transceiver 2, ARM central controller 3 and 6LoWPAN border router 4. Powerlink bus transceiver 1 is bidirectionally connected to ARM central controller 3, Internet bus transceiver 2 is bidirectionally connected to ARM central controller 3, ARM central controller 3 is bidirectionally connected to 6LoWPAN border router 4, and ARM central controller 3 is connected to 6LoWPAN border router 4 communication follows the SLIP communication protocol.

[0059] Such as figure 2 As shown, the connection between the gateway and different external networks is: the ARM central controller 3 communicates with the Powerlink network 5 through the IPV4 communication protocol, and the ARM central controller 3 maps an IPV6 address for each Powerlink device in the Powerlink network 5, The ARM central controller 3 communicates with the Internet network 6 through t...

Abstract

The invention relates to a Powerlink and 6LoWPAN gateway. The technical scheme is that a Powerlink bus transceiver (1) and an ARM central controller (3) are connected in a two-way manner, an Internet bus transceiver (2) and the ARM central controller (3) are connected in a two-way manner, the ARM central controller (3) and a 6LoWPAN border router (4) are connected in a two-way manner, and the communication between the ARM central controller (3) and the 6LoWPAN border router (4) follows an SLIP communication protocol. An ARM processor unit (32) in the ARM central controller (3) is equipped with Powerlink and 6LoWPAN protocol conversion software; and an RF SOC chip (42) in the 6LoWPAN border router (4) is equipped with 6LoWPAN border routing software. The invention has the characteristics of high versatility and low cost, can effectively integrate different networks and is suitable for intelligent enterprises and processing workshops.

Description

technical field [0001] The invention belongs to the technical field of gateways. In particular, it relates to a gateway for Powerlink and 6LoWPAN. technical background [0002] With the progress of society, people's demand for product quality and product replacement rate is getting higher and higher, and the life cycle of products is getting shorter and shorter, which puts forward higher speed and smarter requirements for factory manufacturing; on the other hand, As the global energy resource problem becomes more and more prominent, new requirements are put forward for the energy saving of the factory manufacturing industry. [0003] Traditional industrial field buses such as CAN, DeviceNet, PROFIBUS, and ModBus have low communication speed, poor versatility, complex interconnection, and high cost, which can no longer meet the application requirements of new intelligent factories. Therefore, many new high-speed Ethernet industrial Buses, such as Powerlink and EtherCAT, etc...
