Anti-vibration hammer, as a key fitting to suppress the periodic vibration and galloping of transmission line wires, plays a very important role in the safe operation of transmission lines. This paper takes UAV aerial images of transmission lines as the research object. Aiming at the small target characteristics of the anti-vibration hammer, a transmission line anti-vibration hammer fault identification algorithm based on the improved YOLO V4 model is proposed. First, this method merges the globalized information obtained after expanding the receptive field with the refined local information. Secondly, use multi-scale convolution kernels to obtain more refined local features, and then use different-scale hollow convolution layers to increase the receptive field and obtain more global data. Finally, the obtained information of different scales is fused. The comparison test with the original model proves that the improved model has a significant improvement in the accuracy of detection.

With the development of new network communication technology and tourism information upgrade, the development of smart tourism in China has certain basic conditions and the all-round development of “smart tourism” needs the full transformation of all walks of life. As one of the important links in tourism, “living” should also be transformed to develop “smart hotel” embodying wisdom and to promote the all-round development of “smart tourism”. The support of index system is the key to good development and the establishment of smart hotel index system will bring certain establishment criteria to the smart hotel. But at present the evaluation of domestic smart hotel lacks a complete set of system, which leads to the construction of smart hotel can't be grasped as a whole. In addition, the emphasis of smart hotel construction is also different, and different service subjects have different requirements for intelligence. In this paper, on the basis of establishing the evaluation index system of smart hotel, the weight of each index is analyzed and reasonable suggestions for the intelligent construction of hotels in Jinan are put forward through empirical research.

Satellite antennas that work with linear polarization need to be adjusted for polarization. According to the theory that any polarized wave can be synthesized by two orthogonal linear polarized waves in space, a method of automatic polarization adjustment is proposed. The method achieves automatic polarization adjustment by controlling the amplitude ratio of two orthogonal linearly polarized waves. This paper discusses the principle of automatic polarization adjustment, gives the method of automatic polarization adjustment which can be used in engineering, and verifies the veracity of this method through the actual measurement.

The electromagnetic radiation generated by the operation of the electrical isolation switch will cause electromagnetic interference problems such as the insulation risk of the primary side of the system and the malfunction of the secondary equipment. Electromagnetic interference will directly cause the power grid protection to malfunction or damage, and affect the reliability of the secondary circuit. With the ultra-fast transient overvoltage waveform and frequency components, the process of conduction coupling and radiation coupling is analyzed. According to the process of ultra-fast transient overvoltage passing through CT, CVT and space electromagnetic field, the mechanism of secondary cable interference is discussed. The following models are established, a line model with distributed parameters, a model of an isolating switch with repeatable breakdown, a model of an isolating switch with opening and closing resistors, and a phase-controlled circuit breaker. Numerically calculate the overvoltage generated by the internal disconnector and circuit breaker operating the no-load circuit. Numerical calculations are made for the overvoltage generated by the disconnector and circuit breaker operating the no-load circuit. Combined with the analysis method of the typical circuit of the power system, the overvoltage analysis model of the electrical isolation switch is established, and the electromagnetic radiation characteristic simulation is realized. Experiments show that during the whole process of the isolation switch closing operation, the isolation switch will break down hundreds of times. The short-line disturbance voltage follows the change of the power frequency power supply voltage in a jump mode, presents a step voltage wave, and the overvoltage disturbance lasts for several hundred milliseconds.

The Virtual Travel Communities (VTCs) are widespread and influential platforms for sharing tourism information and experiences. Attracting and maintaining users are crucial to success of them. Despite senior have become second largest tourism market; there is little research on the importance of developing VTCs for seniors. This study aims to explore the functions of VTC for seniors by reviewing the literature on senior tourism, virtual community, and VTC; and then to discuss the strategies for designing VTCs for seniors. This paper devoted to increase the attention on VTC for seniors by exploring the benefits of its development. It will help academics and practitioners gain insights into exploring and maintaining senior users in VTCs.

On the basis of role access control, combined with the role table of this domain and the role table of foreign domains, the inter-domain trust is introduced, and a feedback-based user trust cross-domain access control model-UTKYFKM is proposed. The UTKYFKM model passes trust between different domains. To obtain the user's qualifications to access foreign domains, integrate the user's trust value and resource access execution degree, determine the credibility of user behavior, and combine the foreign domain role table, the system assigns users foreign domain roles, and the user will be externally based on the permissions corresponding to the foreign domain roles. The domain resource object performs the actual access operation and feeds back the execution degree of the access. The feedback feature of this model can detect wrong access control in time and improve the security of cross-domain access control for users.
