Abstract

The invention relates to a real-time damage sensing and early-warning system for a pressure container. The system comprises a signal generating unit, a signal exciting terminal, a signal receiving terminal, a matrix switch, a signal display unit and a computer, and each of the signal exciting terminal and the signal receiving terminal comprises a ceramic piezoelectric plate array; and the signal generating unit generates a first electric signal, the first electric signal goes through the matrix switch and is converted to a pressure signal by the signal exciting terminal, the pressure signal goes through the pressure container, is received by the corresponding signal receiving terminal and is converted into a second electric signal, the signal display unit receives the second electric signal through the matrix switch, displays the second electric signal and transmits the electric signal to the computer, and the computer realizes the state monitoring of the pressure container according to the second electric signal. Compared with systems in the prior art, the system solves the problem of difficulty in real-time sensing and early-warning of guided wave-based pressure container damages, and can timely and effectively avoid the catastrophic damages of the pressure container.

Description

technical field [0001] The invention relates to a damage real-time sensing and early warning system for a pressure vessel, in particular. Background technique [0002] Pressure vessels are special equipment widely used in production and life that may cause explosion or poisoning. Due to various problems in the design, manufacture, installation and operation of the pressure vessel in service, it leads to abnormal failure, resulting in sudden damage accidents. Real-time perception and early warning of pressure vessel damage can monitor the health status of pressure vessels in real time, provide guidance for further shutdown detection, and effectively avoid catastrophic accidents. However, traditional non-destructive testing techniques for damage and defects of pressure vessels (such as: ray technology, magnetic testing technology, eddy current testing, ultrasonic technology, surface coating technology, etc.) cannot realize real-time online monitoring of pressure vessels, and ...
