Embodiment

[0062] This embodiment is implemented on the premise of the technical solution of the present invention, and provides detailed implementation methods and processes.

[0063] The present invention selects ARM framework chip STM32F103 micro-controller of STMicroelectronics Company, the network controller selects Ethernet controller ENC28J60; data display adopts TFT2.4-inch liquid crystal display screen.

[0064] The control process of the data collection terminal: the control of the data collection terminal adopts the multi-task method, and the data transmission adopts the connectionless UDP protocol. The data acquisition terminal works in the Ethernet environment, and the data transmission is relatively stable, so there is no need to use the TCP protocol for reliable transmission (the "three-way handshake" of the TCP protocol increases the amount of additional data). The main tasks of controlling the data acquisition terminal are as follows: figure 2 As shown, it includes: wo...

Abstract

The invention discloses a welding process information acquisition and quality monitoring system based on an Ethernet. STM32 is used as a remote data acquisition terminal main control unit for receiving welding parameters acquired by a sensing device in real time and implement analog / digital (A / D) conversion; and the STM32 sends A / D conversion data to a main control server by using an ENC28J60 and using a user datagram protocol (UDP) through a switch, receives control commands, and returns response information to the main control server. If the main control server sends an acquisition instruction, the STM32 executes A / D conversion and sends the result to the main control server, the main control server converts the result into current and voltage parameters, and the parameters are displayed and stored in a waveform mode; and by adopting command interaction in the main control server, all terminals connected with the main control server execute the acquisition command according to the specified requirement, acquire running state information of welding equipment and display states in real time to finish remote online monitoring operation of the welding equipment.

Description

technical field [0001] The invention relates to an Ethernet-based information collection system, in particular to a collection of actual welding process information (current, voltage) data at multiple stations through the Ethernet, and monitoring welding quality by using the collected information. Background technique [0002] With the development of advanced manufacturing technology, the automation, informatization and intelligence of the welding process have become an inevitable trend. In the field of welding, whether it is processing, quality assessment, or scientific research, data support is required. Welding is very easily affected by external conditions and is closely related to the skills of the welding operator itself. Therefore, the quality of welding is directly related to the key factors of product quality. How to effectively obtain the data of the welding process is an important basis for analyzing the welding quality. In the welding production process, usuall...
