Abstract

The present invention relates to the technical field of non-destructive testing, more specifically, an electromagnetic ultrasonic online monitoring system based on a pulse compression method, including an electromagnetic ultrasonic monitoring host, a monitoring network, a cloud server, and a client. To monitor the workpiece under test, the electromagnetic ultrasonic monitoring host is connected to the monitoring network, the monitoring network is connected to the cloud server, and the client is connected to the cloud server. According to the size of the workpiece to be tested, the electromagnetic ultrasonic monitoring host is adsorbed and It is installed on the workpiece in a detachable way such as cable ties. The control circuit controls the low-voltage pulse compression circuit to excite the low-voltage coded pulse train, and the electromagnetic ultrasonic transducer transmits and receives the low-voltage coded electromagnetic ultrasonic signal; the signal is collected and passed through the wireless The communication circuit sends the data to the monitoring network, and the monitoring network sends the data to the cloud server for calculation and analysis, and the results are returned to the client for display.

Description

technical field [0001] The invention relates to the technical field of nondestructive testing, and more specifically relates to an electromagnetic ultrasonic on-line monitoring system based on a pulse compression method. Background technique [0002] There are a large number of pipelines and storage tanks in petroleum, chemical, natural gas, nuclear power and other industrial fields. During use, due to local stress concentration, chemical changes in contents, surface oxidation and other factors, some weak parts of the inner and outer walls of pipelines and storage tanks are prone to defects such as corrosion and cracks. If these defects are not discovered in time, after development, the wall thickness will be thinned and perforated, which will lead to the leakage of oil, fuel, chemical raw materials, etc., which will cause environmental pollution and economic losses, and lead to safety accidents such as explosions and endanger human life. life safety. Therefore, certain te...
