Abstract

The invention discloses an FF field bus control system based on ZigBee and a protocol conversion method thereof. The FF field bus control system based on ZigBee comprises an FF-HSE network, an FF-HSE device, an FF-ZigBee gateway, an FF-ZigBee interface, an FF-H1 network, an FF-H1 device and an analog device. The protocol conversion method comprises the following steps: allocating a virtual FF-H1 device address to a non-FF-H1 device; binding the FF-H1 device address with a ZigBee short address; and converting formats between an FF-HSE data packet and an FF-H1 data packet. By the measures, data interconnection among the FF-HSE device, the FF-H1 device and the analog device in the FF field bus control system is ensured. The invention realizes the interconnection among the high-speed device, the low-speed device and the analog device of the FF bus, overcomes the defect that the analog device can not be accessed into the network, solves the problem of installation of devices in the regions where wires can not be arranged easily, reduces the installation cost of the control system, and has an open system and good expandability.

Description

technical field [0001] The invention relates to the field of FF field bus, in particular to a ZigBee-based FF field bus control system and a protocol conversion method thereof. Background technique [0002] Fieldbus technology was produced in the 1980s and is the product of the intersection and integration of control, computer, and communication technologies. Fieldbus has the advantages of simple structure, high reliability, strong controllability, good interoperability, strong comprehensive functions, decentralized control, and open system. With the maturity and wide application of Ethernet and TCP / IP technology, the combination of field bus and network technology has become a hot issue in the field of field bus. [0003] The FF fieldbus specification is jointly formulated by many world-renowned instrumentation and automation equipment manufacturers and scientific research institutions. Because these enterprises and institutions are the main suppliers and research and dev...
