Information exchange device capable of being dynamically configured

Abstract

The invention relates to an information exchange device capable of being dynamically configured, which comprises a digital signal processor, a CAN bus interface, a CAN open bus interface and an RS232 communication interface, wherein the digital signal processor is provided with an external storage, and a driver module, an operation system module and an application module are arranged in the digital signal processor; the storage stores parameter configuration files and can be connected with a remote configuration device through the RS232 communication interface to modify the parameter configuration files; the driver module contains a driver used for driving external hardware of the digital signal processor; and the application module comprises a CAN module, a CAN open module, a file system module, an SCI communication module and a parameter configuration module. By simply modifying the parameter configuration files, the information exchange device can meet different requirements of different clients, has wide application range, and does not need independent development and design for each client so as to save labor and cost.

Description

technical field [0001] The present invention relates to the information exchanging device that is used for network, relate in particular to be used for having CAN (Controller Area Network, controller local area network) communication interface equipment and CANopen (the application layer agreement of CAN bus line, is CAN-in-Automation (CiA) One of the standards defined) A dynamically configurable switching device between networks. Background technique [0002] CANopen network is a network specially designed for industrial field bus, and has become a high-reliability field bus network widely used at home and abroad. Because the CANopen network is too professional, the external interface is not particularly convenient. The CAN communication method is one of the most widely used communication methods at present. It has the advantages of simple interface, low price, convenient debugging, and reliable performance. Especially in urban light rail, subway, automobile and other fiel...

Problems solved by technology

[0003] The information exchange device (also known as adapter) disclosed in Chinese patent CN201199700Y has solved the data flow interaction from the CAN network to the CANopen network. The hardware parameters, CANopen protocol parameters, CAN protocol parameters and data mapping relationship of the information exchange device are uniquely determined and fixed. On the information exchange device, not reconfigurable

[0007] 4) The position where the OD object data on the CANopen end is mapped to the PDO is uncertain

[0008] When the application environment changes slightly, the information exchange device that can only be used in a specific environment cannot meet the work needs, and needs to be re-developed and designed, so that many unnecessary resources will be repeatedly consumed in terms of manpower and financial resources

Therefore, how to change the defect that the traditional information exchange device can only be used in a specific environment and has a small application range is a problem to be solved urgently in this field
