Embodiment Construction

[0030] In order to make the object, advantage and technical solution of the present invention clearer, the specific implementation manners of the present invention will be briefly introduced below in conjunction with the accompanying drawings.

[0031] figure 1 It is a system structure diagram of the data acquisition system 100 in the embodiment of the present invention. The data acquisition system 100 includes a bottom hardware subsystem 10 , a data communication subsystem 20 , a data storage subsystem 30 , a data download subsystem 40 , and a system self-diagnosis subsystem 50 .

[0032] Please see figure 2 , the data communication subsystem 20 includes a storage module 21 and an underlying hardware subsystem interface module 22 . The storage module 21 stores a configuration file and an OPC connection library. The underlying hardware subsystem interface module 22 is used to set and read the configuration file stored in the storage module 21 and establish a connection with...

Abstract

Provided in the invention is a data acquisition system comprising a bottom layer hardware subsystem, a data communication subsystem, a data storage subsystem and a data downloading subsystem. The data communication subsystem connected with the bottom layer hardware subsystem by a corresponding connecting way is used for obtaining data of the bottom layer hardware subsystem, wherein the connecting way includes an OPC connection way, an ADS connection way, a TCP / IP connection way, or a serial port connection way. The data storage subsystem connected with the data communication subsystem is used for obtaining the data of the bottom layer hardware subsystem from the data communication subsystem and storing the data. The data downloading subsystem connected with the data storage subsystem is used for receiving a downloading request of a user and downloading corresponding data stored by the data storage subsystem according to the downloading request. According to the data acquisition system, the connection way with the bottom layer hardware subsystem can be configured flexibly; and the transportability, universality, and practicability are high.

Description

technical field [0001] The invention relates to the field of data acquisition, in particular to a data acquisition system. Background technique [0002] Since the distributed control system has been fully used in the field of industrial automatic control, real-time databases have become more and more important. The real-time database needs to collect a large amount of industrial field data in real time and save them for use by the host computer software. Collecting a large amount of industrial field data will involve various sensors and PLCs. Since various sensors and PLCs usually come from different manufacturers, a complete set of data acquisition and control software needs to be developed separately for communication between devices and communication between devices and the host computer. For example, the control systems of amusement equipment often use products from different manufacturers, such as Siemens, Omron, Beckhoff, etc., and their system structures and communic...
