Distributed multi-terminal concurrent data acquisition and analysis system

Abstract

The invention discloses a distributed multi-terminal concurrent data acquisition and analysis system. The system is formed by a measurement analysis system and data acquisition terminals, and a miniature distributed measurement and control system is formed. The task of each data acquisition terminal is to finish acquisition and storage of industrial on-site data; and the main task of the measurement analysis system is to be responsible for data analysis and management. Parameters of the plurality of data acquisition terminals are set through the measurement analysis system, and synchronous acquisition of the data is realized. The data acquisition terminals are externally connected high-capacity memories to enlarge storage capacity thereof. The system can realize synchronous acquisition and storage of on-site data of the same type of devices in different regions, carries out off-line data display, analysis and processing on the data in a mobile device in the measurement analysis system, and finds out and records the reasons of faults so as to provide reference for the subsequent analysis of the kind of device data. The system can realize synchronous acquisition, storage and analysis of multi-time and multi-occasion data, is convenient to carry and low in cost, and has good practical values and market prospect.

Description

technical field [0001] The invention relates to a data acquisition system, in particular to a distributed multi-terminal simultaneous data acquisition and analysis system. Background technique [0002] With the development of science and technology and the improvement of industrial manufacturing level, the measurement objects of modern test and measurement systems are becoming more and more complex, and the distribution of measurement sites is becoming wider and wider. This change prompts the test and measurement system to develop into a distributed and multi-channel system to meet the needs of multi-site and multi-attribute real-time acquisition. At the same time, test and measurement systems continue to develop in the direction of miniaturization, mobility, and multi-function. [0003] The existing data acquisition module communicates with the upper computer through RS-232, RS-485 and other wired methods or network. The data acquisition modules that can be hung on the bu...

Problems solved by technology

Representative examples include: the 262XA series data collectors of Fluke Corporation of the United States, the high-speed portable data acquisition system of Smart Instrument Corporation of the United States, etc., and what they have in common is that the communication with the PC basically uses the RS-232 port, although they It has its own memory, but the storage capacity is limited, and it cannot realize synchronous measurement

[0006] In workplaces with severe industrial noise, outdoor and harsh environments, a data acquisition system with small size, low power consumption, large storage capacity, and data that can be measured synchronously and stored for a long time is required, and many domestic detection systems lack the ability to detect data Comprehensive Utilization and Management
