“…In order to ensure that the methods and methods of testing are scientific and effective, it is necessary to carry out the inspection of the related materials used in houses and buildings in combination with the specifications in this area and follow the standards in order to ensure that the methods and methods of testing are scientific and effective. Thus it can be seen that no matter what type of housing construction project, in the whole process of construction, it is necessary to carefully detect the materials involved in the relevant housing construction, which is not only conducive to fully ensuring the construction quality of the housing construction project, but also effectively ensures that the safety of the construction personnel is not threatened [ 5 – 7 ].…”

In order to improve the quality detection ability of thermal insulation building material, a phase change energy storage thermal insulation building material quality detection method based on neural network is put forward. The double broken line model is used to detect and evaluate the quality of phase change energy storage thermal insulation building material. Combined with the material stress characteristics and dissipation characteristics, the seismic evaluation of phase change energy storage thermal insulation building material is carried out, and the self-recovery energy dissipation support model of phase change energy storage thermal insulation building material is established. Under the constraint of quality parameter constraint model and neural network control model, the quality of phase change energy storage thermal insulation building materials is evaluated quantitatively by using network adaptive control method, and the stress distribution characteristic parameters of phase change energy storage thermal insulation building materials are calculated respectively to realize the quality detection of phase change energy storage thermal insulation building materials. The simulation results show that the accuracy of phase change energy storage and thermal insulation building material quality detection is high, the accuracy of parameter evaluation is good, and the quality detection ability is very good.

“…Previous studies also utilised the frequency-modulated continuous THz imaging method to test the bonding samples of aerospace thermal insulation composites. The bonding defects between thermal insulation composites and bonded substrates were investigated by combining image processing techniques [90]. Successful case studies have been reported to detect bonding defects in non-metal/metal bonded structures using the THz-TDS technique, which involve detecting information, such as signal amplitude, phase, refractive index, F I G U R E 1 1 Cable terminal degradation diagnostic procedures using the Acoustic emission (AE) technique [80].…”

Composited cable terminals are critical for reliable power delivery of traditional and traction power supply systems. During its operation, the cable terminal continually undergoes complex circumstances where humidity, temperature, field strength, mechanical stress and other factors continuously change at different levels. In extreme cases, defects or even failures may occur in the cable terminals, leading to catastrophic accidents. This makes the condition monitoring and defect detection of composited cable terminals become an imperative need for the power industry. The “state‐of‐the‐art” technology of cable terminal condition assessment is focussed and a systematic review of the current research progress of cable terminal condition assessment from the operation circumstances to failure mechanisms is provided. It covers both online/offline condition monitoring methods and defects detection approaches. In addition, challenges and future research directions for cable terminal condition assessment are also addressed. It is concluded that the non‐destructive and non‐intrusive methods like terahertz imaging and ultrasonic testing, and multi‐source information fusion methods as well as the digital twin technology have been gaining popularity for cable terminal defect inspection. It is expected the presented work can provide a global field of vision for further advancement of both scholars and industrial engineers in this field.
