Abstract
A single sensor is used to obtain welding information in welding monitoring process, but this method has some shortcomings. In order to obtain more comprehensive and reliable welding information, this paper designed and built a welding multi-information wireless monitoring system with STM32-F407ZET6 as the control core and ALK8266 as the wireless transmission module. Real-time acquisition, transmission and display of electric arc signal and welding image information are realized in the monitoring system. This paper mainly introduces the hardware and software core of the monitoring system. At the same time, the signal collected by the monitoring system is compared with the original signal, and the accuracy of the remote monitoring system is tested. The monitoring system is used in welding test. The test results show that the accuracy of the monitoring system meets the requirements, and the on-line monitoring of electric arc signal and welding image can be realized in the welding process.

With the development of welding automation, it becomes more and more important to monitor the welding process on-line effectively
The test results show that the accuracy of the monitoring system meets the requirements, and the on-line monitoring of electric arc signal and welding image can be realized in the welding process
The on-line monitoring of the welding of information acquisition is the most critical step, but the information obtained by a single sensor has shortcomings in terms of comprehensiveness and reliability, such as using hall current electrical signal can obtain in the process of welding arc voltage and the arc electrical signal ob
Summary
With the development of welding automation, it becomes more and more important to monitor the welding process on-line effectively. At the same time, considering that due to the welding field industrial equipment, personnel and the actual situation with big liquidity caused by the traditional wired monitoring wiring difficulties, low extensibility, communication distance is restricted, increased costs and other issues, the monitoring system designed in this paper adopts ALK_8266 wireless transmission module, connects the network through the router node, and uses modBUS-TCP communication protocol for the communication between the remote acquisition terminal and the remote monitoring terminal [6] [7] It is flexible in networking and has achieved good results in practical application [8] [9] [10]
