Problems solved by technology

[0003] The biggest disadvantage of this architecture is that the data collector and the sender are not the same device, so two MCUs (micro control units) need to interact, the workload is huge, and it is easy to make mistakes
[0004] At the same time, when using various MCUs for data collection and transmission, there are the following three difficulties: (1) The sampled data is continuously generated, which is a high-frequency event, but the frequency of transmission is very low. How to solve the problem of sampling The problem of inconsistency between the rate and the sending rate and frequency makes the sampling and sending of data reach a balanced state; (2) If the network situation is not smooth, how to ensure the integrity of data transmission and not lose data; (3) The sampling frequency is often relatively high , which means that the time taken by the sending operation must be short enough, otherwise the next sampling time will be delayed

Embodiment Construction

[0041] The invention relates to a data acquisition system of machine equipment, which uses NodeMCU as a main controller, and uses Lua language to program NodeMCU.

[0042] The system machine equipment data acquisition system includes: a configuration module, a queuing module, a confirmation removal module, a sending module, a task module, and an initialization module.

[0043]The configuration module (i2cDevs module) is used to test the existence of ADXL345 and BMP280, then perform basic configuration, and finally return an object. The object returned by the configuration module contains several methods for reading the internal values ​​of the sensor. The read The internal data of the sensor is the original register data.

[0044] The queuing module (Queue module) is used to delete all the files starting with "qf_" in the flash memory, then build a queue that depends on the file system, and finally return an object representing the queue. The object returned by the queuing mod...

Abstract

The invention relates to the technical field of data acquisition, and aims to provide a machinery equipment data acquisition method and a data acquisition system, which can balance the acquisition rate and transmission rate, ensure that a transmit operation occupies shorter time, can still guarantee the complete transmission of data under the condition that a network is not smooth, and ensure thatthe data are not lost. According to the method, a NodeMCUrrent is used as a master controller to acquire the data, and data transmission is carried out through a TCP protocol at the same time. The method specifically comprises three parts, namely data acquisition, WiFi reconnection and data transmission. The data acquisition system based on the data acquisition method comprises a configuration module, a queue module, a confirmation removal module, a transmission module, a task module and an initialization module.

Description

technical field [0001] The present invention relates to the technical field of machine equipment data processing, in particular to a machine equipment data acquisition method and an acquisition system. Background technique [0002] There are many ways to collect data from machinery and equipment in the market: the most common way now is to use Arduino to collect data. Arduino is an open source platform used to build electronic products. Combined with ESP8266, it can send the data collected by itself to the designated place. The architecture of using Arduino to collect sensor data and then command ESP8266 to send through AT commands, such as figure 1 shown. [0003] The biggest disadvantage of this architecture is that the data collector and the sender are not the same device, so two MCUs (micro control units) need to interact with each other, the workload is huge, and it is easy to make mistakes. [0004] At the same time, when using various MCUs for data collection and t...
