Data acquisition paperless recorder based on Internet of Things

Abstract

The invention relates to the technical field of material recorders, and discloses a data acquisition paperless recorder based on Internet of Things. The data acquisition paperless recorder comprises a pcb, a DAQ board card, a key circuit, a power amplifier circuit, an alarm module, an acquisition module, a communication module, a gateway module and a virtual module, wherein the pcb is in communication connection with a single-chip microcomputer; the single chip microcomputer is used for processing the data; the acquisition module is in communication connection with the single-chip microcomputer; the acquisition module is used for acquiring data so as to send the data to the single chip microcomputer for processing; the keys are in communication connection with the pcb through the key circuit; the keys are used for manual control and selection; the power amplifier circuit is electrically connected with the pcb; the power amplifier circuit is electrically connected with the alarm module; the power amplifier circuit is used for driving the alarm module; and the alarm module is used for alarming the abnormal information. The invention provides a data acquisition paperless recorder based on the Internet of Things. According to the data acquisition paperless recorder, the correctness of identification and operation is improved; and the simplicity of operation and the simplicity of panel arrangement are improved.

Description

technical field [0001] The invention relates to the field of material recorders, in particular to a paperless recorder for data collection based on the Internet of Things. Background technique [0002] The paperless recorder records the collected data / computational data in the internal storage system of the instrument based on time, without consuming any common recording facilities, such as paper, pen and ink. The stored data recorded in the instrument is displayed on the LCD screen after calculation and simulation. Commonly used LCD screens are widely used for display. On the LCD screen, digital display, bar graph display, curve display, alarm list, etc. can be displayed. The data collected by the paperless recorder are commonly used: temperature, pressure, flow, liquid level, voltage, current, humidity, frequency, vibration, speed, etc. The paperless recorder has the characteristics of paperless recording, good real-time performance, high precision, communication, searc...

AI Technical Summary

Problems solved by technology

[0003] The traditional analog recorder has a simple structure and a single function, and there are prone to failures such as paper jams, pen jams, and disconnection, as well as a large number of daily maintenance tasks such as changing pens, paper, and ink.

Due to the limitations of its structure and functions, this type of recorder cannot meet the needs of comprehensive production management, intelligent production process, data transmission network and online data analysis and processing.
