Problems solved by technology

[0002] Industrial field data acquisition and monitoring generally adopts mature industrial control configuration software, such as the combination of WinCC (Windows Control Center) and PLC. For example, the widely used CAN communication protocol cannot directly communicate with the purchased industrial control software. The common solution is to use OPC (OLE for process control). The data formats of the two are different. Build a data bridge between industrial control configuration software

Abstract

The invention discloses a data acquisition monitoring system and acquisition monitoring method based on a CAN bus and an OPC (OLE for process control) technology. The system comprises an upper computer and data conversion equipment connected with the upper computer by a network cable; the data conversion equipment is connected with a plurality of detection devices by CAN communication wires; and the detection devices are connected with corresponding to-be-detected equipment. The method comprises the following steps of: (I) data processing of frames received by the upper computer; (II) data conversion of the frames received by the upper computer; (III) debugging on the detection devices; and (IV) operation of the detection devices. The invention provides the field data acquisition monitoring system suitable for industrial application, so that transmission of instructions and data between acquisition monitoring software and the detection devices is implemented, equipment parameters which need to be monitored are acquired by utilizing the detection devices and data (detection results) is shared with other clients in an OPC mode.

Description

technical field [0001] The invention belongs to an on-site data acquisition and monitoring system for industrial use, and in particular relates to a data acquisition and monitoring system and an acquisition and monitoring method based on CAN bus and OPC technology. Background technique [0002] Industrial field data acquisition and monitoring generally adopts mature industrial control configuration software, such as the combination of WinCC (Windows Control Center) and PLC. For example, the widely used CAN communication protocol cannot directly communicate with the purchased industrial control software. The common solution is to use OPC (OLE for process control). The data formats of the two are different. Build a data bridge between industrial control configuration software. Contents of the invention [0003] The present invention is proposed in order to overcome the shortcomings existing in the prior art. Its purpose is to provide a data acquisition monitoring system an...
