Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the data acquisition device based on current analysis provided by the invention comprises a data acquisition box, a power supply module and a current transformer, wherein the power supply module supplies power to the data acquisition box and the current transformer, the current transformer transmits acquired device current signals to the data acquisition box, the data acquisition box comprises an operation module, an I/O module and a 4G module, and the operation module is respectively in data transmission with the I/O module and the 4G module.
Further, the data acquisition box is installed in the equipment control cabinet, and the current transformer is installed on the main cable of the equipment.
Further, the 4G module uploads the operation result to the cloud platform server.
Further, the I/O module is in data transmission with a current transformer.
When the device is in operation, the load will be larger than the standby operating current. However, the current values received by the data acquisition box are different due to different load degrees. The data acquisition box intercepts the time point of the change of the current, and automatically calculates the current state of the equipment and the number of the processed parts by combining the data of a period of time before the current changes.
Collecting current values in a sampling period once every second, calculating and storing difference values of every two adjacent current values, comparing the magnitude of each difference value, and respectively calibrating the two current values corresponding to the largest difference value as the end point of the previous interval and the starting point of the next interval. And by analogy, three intervals are obtained, wherein the three intervals are in three states of shutdown, standby and operation respectively from small to large current values, and a plurality of current values of the three states are finally obtained respectively through cyclic detection.
In conclusion, the data acquisition unit based on current analysis is simple in equipment field installation and convenient to debug; the current information of a main cable of the equipment is collected through the current transformer, historical sample data of the equipment is combined, an edge calculation technology is adopted, and the data collection box judges the current on-off state and the number of processed parts of the equipment and uploads the data.
The above description is only an example of the present invention, and is not intended to limit the present invention, and it is obvious to those skilled in the art that various modifications and variations can be made in the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
