Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] According to one or more embodiments, a kind of heterogeneous industrial fieldbus fusion system is disclosed, and two kinds of industrial fieldbuses with high market share and wide application range, CANopen and Modbus RTU, are selected, such as figure 1 As shown, it includes the Modbus control network support module, the CANopen control network support module, and the gateway support module integrating the field bus.

[0041] Take CANopen and Modbus RTU as an example of the industrial field bus intercommunication system, such as figure 1 and figure 2 As shown, specifically include:

[0042] Modbu control network support module, which includes baud rate configuration, transmission mode configuration, master / slave communication query-response mechanism, slave station message pool, gateway message pool and RS-485 hardware driver.

[0043] CANopen con...

Abstract

The invention discloses a heterogeneous industrial field bus fusion method and a heterogeneous industrial field bus fusion system, which solve the defects of poor isomerism and poor software maintenance and reliability caused by coexistence of field bus standards, and are characterized in that: aiming at a heterogeneous industrial field bus protocol, a master station/slave station control network is constructed, and based on a Modbus RTU (Remote Terminal Unit) message model and a CANopen message model, a CANopen message model is established; under the support of a data structure and a processing function provided by a set RTOS, parameters are obtained, a packing and unpacking mechanism of Modbus RTU and CANopen information frames is constructed based on a queuing network model, and when data are continuously exchanged between two protocols, management of interaction tasks and management of a buffer area are abstracted into a multi-task, multi-queue and multi-service mode. According to the heterogeneous industrial field bus fusion method and the heterogeneous industrial field bus fusion system, equipment hooked on various industrial field buses can be conveniently fused to an IT network, and industrial field bus network intercommunication and fusion are realized.

Description

technical field [0001] The invention relates to industrial field bus technology, in particular to a heterogeneous industrial field bus fusion method and system. Background technique [0002] At present, there are more than a dozen fieldbus technologies widely used in the industrial Internet of Things market, which effectively solve the communication and control command transmission problems among industrial instruments, controllers, actuators, and electromechanical equipment. However, the heterogeneity caused by the coexistence of various types of fieldbus standards has brought troubles to communication regulations, user selection, and hardware implementation. At the same time, the system software support corresponding to fieldbus is flourishing, and there is no unified and open design. It is difficult to reflect the reusability of software, which increases the cycle of software development, and its maintainability and reliability are also poor. Contents of the invention ...
