Embodiment Construction

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

[0040] refer to figure 1, the present invention is mainly composed of a CAN bus interface unit, a CAN bus communication control unit, a data conversion unit, and a PCI bus control unit, and each unit is bidirectionally connected by a data / address line and a control line. The CAN bus interface unit is used to receive the communication message on the CAN bus, convert the differential level on the bus into a digital logic level, and transmit it to the CAN bus communication control unit. The CAN bus communication control unit performs filtering, conversion and scheduling processing on the converted CAN message data, and transmits it to the data conversion unit, which transmits the processed CAN bus message information to the PCI bus control unit and PC The controlled PCI bus performs data exchange and completes the communication with the upper control machine.

Abstract

This invention relates to an intelligent management apparatus and management method for distributed control network based on CAN bus. Wherein, the CAN bus interface unit receives communication message on the bus to convert the differential voltage level into the digital logic level for filter, conversion and scheduling, sends the processed data to the data conversion unit and PCI bus control unit for data exchange to complete the communication with superior control machine; applying the software functional module in ARM chip for network communication, performance detection, fault diagnosis, data management, and protocol conversion. This invention improves whole network real-time feature and fit to industrial control field.

Description

technical field [0001] The invention belongs to the field of industrial automation control, and in particular relates to a communication management device of a distributed control network based on a CAN field bus of a controller area network and an interconnection management method between subnets. Background technique [0002] CAN bus is a serial data communication bus developed to solve the data exchange between control and test instruments in modern automobiles. CAN bus technology has high real-time and reliability, and has been widely used in industrial sites. However, with the continuous complexity of the control network structure used by the CAN bus and the increase of the system scale, the CAN bus itself lacks support for high-level network protocols, so it is not perfect in the detection, diagnosis and management of the communication network. There are also many difficulties in the interconnection between homogeneous and heterogeneous control sub-networks. [0003]...
