Data acquisition device

Abstract

The invention discloses a data acquisition device. The device comprises a power supply module, an MCU module, a state display module, a communication module, a data acquisition module, a serial interface module, and an internal bus for connecting the above modules. The data acquisition module further comprises a first external memory for storing a configuration file, an attribute file and a flag bit and a second external memory for storing historical data and debugging information; the MCU module comprises a data calculation unit for calculating the acquired data according to a calculation formula in the configuration file, a data packaging unit for converting the collected data into data in a unified format, and a data sending unit for sending newly collected data or historical data in the second external memory to a host through the communication module according to an exception handling mechanism. The collected data can be prevented from being lost in the uploading process in an unstable network environment. The invention discloses a data acquisition device, which belongs to the technical field of industrial communication.

Description

technical field [0001] The invention relates to the technical field of industrial communication, in particular to a data acquisition device. Background technique [0002] As the front end of the condition monitoring and diagnosis system, industrial data acquisition is mainly used to convert on-site physical signals into analog signals through sensors, and then convert them into digital signals through the steps of collation, sampling, quantification, and encoding, and then process and store them by computer. and send. The purpose of data collection is usually to realize functions such as remote monitoring of equipment data, remote operation and maintenance of equipment, equipment failure alarm, equipment maintenance reminder, equipment maintenance record, and equipment predictive maintenance. Industrial data acquisition is the primary link of the status detection and diagnosis system. Its accuracy, real-time and reliability directly affect the overall performance of the sys...
