Abstract
The utility model discloses a multi-interface data acquisition unit based on OPC technology, which comprises a keyboard interface, a display interface and a memory interface. The multi-interface data acquisition unit is characterized by comprising an LPC2292 central processing unit, two Ethernet control chips RTL8019AS for communicating with the Ethernet, four USB port modules for communications with a data collection site, two RS-232 interface modules, two RS-485 interface modules and a CAN (controller area network) bus interface module. The number of the data acquisition unit interfaces and corresponding data acquisition software modularization can be added according to actual needs. OPC Server services are provided to the software on an information processing layer based on OPC technology, thereby reducing the compiling difficulty of the client-side software.
Description
Technical field
The utility model relates to data acquisition unit, especially based on the multi-interface data collector of OPC technical design, belongs to data acquisition and processing technology field.
Background technology
In recent years, constantly the infotech of changing is promoting the develop rapidly of the automatically-monitored site technology of industrial and mineral, the industrial communication network of widely applying, as fieldbus, Industrial Ethernet, wireless network etc. show industrial control field just towards system integration, control is decentralized, node is intelligent, the direction of structural networkization develops.In order to comply with the trend of this technological improvement, the solution that it differs from one another is released in each big system integration commercial city.What application was more at present is to utilize configuration software that the production run in workshop is carried out unified monitoring and management, thus the satisfied system complexity that improves constantly and the distributed demand for control of global range.But this type systematic relatively more crucial step in structure is how to realize obtaining fast and concentrating field data, Industrial Ethernet interface, pci interface card, serial ports, parallel port etc. are used more extensive in the current data acquisition system, but data acquisition unit often can not satisfy the access needs of multiple interfaces, promptly when new interface occurring, need increase new interface on data acquisition unit and revise corresponding process software, the adding of new interface has proposed huge challenge to the modification of Information Level processing software code
Summary of the invention
The purpose of this utility model is: based on OPC technological development multi-interface data collector, this collector can be matched rational acquisition interface and respective drive program according to the industry spot needs, and serves for the Information Level process software provides OPC Server.
Multi-interface data collector structure of the present utility model is:
A kind of multi-interface data collector based on the OPC technology, it comprises keyboard interface, display interface device and memory interface, it is characterized in that, it also comprises the LPC2292 central processing unit; Be used for two ethernet control chip RTL8019AS with ethernet communication; Be used for and four usb interface modules of data acquisition on-scene communication, two RS-232 interface modules, two RS-485 interface modules and a CAN bus interface module.
Good effect of the present utility model is: data acquisition unit interface and corresponding data acquisition software modularity, can be according to on-the-spot actual needs extended interface quantity, provide OPCServer service based on the OPC technology to information processing layer software, reduced client software and write difficulty.
Description of drawings
Fig. 1 is the utility model multi-interface data collector schematic block circuit diagram.
Embodiment
As shown in Figure 1, the utility model is to be provided with the LPC2292 central processing unit in the circuit board; Be used for two ethernet control chip RTL8019AS with ethernet communication; Be used for and four usb interface modules of data acquisition on-scene communication, two RS-232 interface modules, two RS-485 interface modules and a CAN bus interface module; As can be seen from the figure, except the interface of each module, also have keyboard interface, display interface device and memory interface.
Principle of work of the present utility model is:
(1) initialization interface configuration.Mainly comprise the initialization operation of module and the processing of various mistakes, wherein the fault processing handle that partly utilizes function to return sets up processing procedure on their own by the user, also can be handled accordingly automatically by system.
(2) data acquisition.Call relevant OPC Runtime Library function by Visual C++6.0 and set up opc server, the API that is provided by data acquisition module simultaneously reads and writes the data of gathering in the equipment, and the data of each passage are write in opc server item/group objects, thereby realized the design of whole opc server.
(3) provide the standard interface service to the OPC of information processing layer client.Opc server is gathered real time data by distinct interface, and these data are open to each client application with the form of OPC item, and the OPC client is by each standard interface of OPC and opc server communications reception data.
