Embodiment 1

[0065] Embodiment 1: In this example, the user uses the local end system to analyze the quality of the welding process. see figure 1 As shown, the current sensor and voltage sensor are connected to the electric welding machine, the sensors are connected to the data acquisition device, the acquisition device is connected to the computer for communication, and the computer communicates wirelessly with the cloud platform through the gateway. Power on all hardware and start the system, put the whole system in standby state. The welding operation is performed, and the system starts to collect current and voltage signals during the welding process. The collected data is sent to the computer by the data acquisition device, such as image 3 As shown, the computer stores and displays the collected data; such as Figure 4 As shown, the software further analyzes the collected data to obtain the characteristic indicators of the welding process.

Embodiment 2

[0066] Embodiment 2: In this example, the user uses the cloud system to analyze the quality of the welding process. First connect the acquisition device to the welding machine, see figure 1 shown. Start the system and put the whole system in standby state. The system starts to collect and perform welding operations at the same time, and collects current and voltage signals during the welding process. The data collected by the data acquisition device is sent to the computer, and the computer uploads to the designated cloud server through the gateway. After the cloud server receives the data, it calculates the characteristic indicators of the welding process, such as Figure 5 , the statistical analysis results are displayed graphically as Figure 6 , users can view the analysis results through multiple terminals.

Embodiment 3

[0067] Embodiment 3: This example uses the system of the present invention to analyze the welding process quality of argon tungsten arc welding. Such as Figure 7 As shown, the user collects the welding process voltage and current information of argon tungsten arc welding in real time, and uploads the data to the cloud platform. If the argon arc welding data is within the standard signal range, it is judged that the welding quality is qualified.

Abstract

The invention discloses a welding process quality online analysis system and method based on a cloud server, and belongs to the technical field of welding process quality online analysis. The technical problem to be solved is to provide the improvement of the welding process quality online analysis system hardware structure based on the cloud server. According to the technical scheme, the system comprises three parts, namely acquisition hardware, analysis software and a cloud platform, wherein the acquisition hardware consists of a current sensor, a voltage sensor, a data acquisition device, a computer and a gateway; wherein the analysis software is used for processing the collected current and voltage signals, carrying out data processing and statistical analysis on the electric signals through edge calculation and cloud calculation, and providing characteristic index parameters for welding quality analysis; the cloud platform receives the data information transmitted by the gateway, stores the data information in a database of the cloud platform, performs data processing and classified management, and allows the multiple terminals to access the cloud platform through a browser at any time. The technical scheme is applied to welding quality analysis.

Description

technical field [0001] The invention discloses a welding process quality online analysis system and method based on a cloud server, belonging to the technical field of welding quality detection. Background technique [0002] With the upgrading of my country's manufacturing industry, traditional welding manufacturing is developing rapidly in the direction of intelligent welding manufacturing and robot welding, and welding intelligent manufacturing characterized by "digitalization, informationization, networking, and intelligence" has become inevitable; welding quality online monitoring platform It is the key to realizing welding intelligent manufacturing. [0003] At present, most welding quality analyzers use a stand-alone operation mode to complete the data collection and quality analysis of a single production process. For example, the welding process analysis instrument of German HKS company monitors industrial production units. The product integration is high but the acq...
