“…Currently, the fault judgment strategy of association rules is shown in Figure 1 below. As can be seen from Figure 1, the above-mentioned association rule fault judgment strategy has obtained different judgment attributes in the implementation process, and it is necessary to use the improved Apriori algorithm to calculate the importance of association rules [7][8], as shown in Equation (2). ( ) p B notA represents that the importance of B is higher than that of A.…”

Aiming at the traditional 10 kV line trunk outage fault judgment logic which mainly adopts the fixed receiver to collect the emergency repair work instructions and is susceptible to the influence of restrictive logic transmission, resulting in the problem of low fault judgment feedback integrity, it is necessary to design a new association rule-based 10 kV line trunk fault judgment logic. The association rules are used to generate the trunk fault judgment strategy, clarify different fault judgment attributes, and calculate the importance of the association rules by the improved Apriori algorithm. Combined with the spatial information service and the basic application service, the information interaction is realized through the bus exchange to generate the optimization logic of the 10 kV trunk fault judgment and complete the trunk fault judgment. The results of the example analysis show that the designed trunk line outage judgment logic has high feedback integrity, which proves that the designed outage judgment logic is effective and reliable with a certain application value, and makes a certain contribution to reducing the risk of trunk line outage.

“…Researchers of [8] propose an Advanced Deep Learning framework for Fault Diagnosis in Industry 4.0 (ADL-FDI4), which combines Long Short Term Memory (LSTM), Convolutional Neural Networks (CNN) and graph CNN (GNN), to handle heterogeneous data. Paper [10] focus on the detection of soft faults and the localization of the faulty branch in star-shaped networks with the comparison between a network Reference Transmission Coefficient (RTC) and a TC measured online through power line communication using Orthogonal Frequency Division Multiplexing (OFDM) scheme. An automated fault diagnosis model that can diagnose multiple types of faults in the category of hard faults and soft faults is present in [11] and a CAN communication detection system is designed in [13] to analyze and diagnose the physical link faults of CAN based on "handshake" theory for the engineering vehicle ECUs.…”

Fault diagnosis, location and maintenance of industrial networks are extremely important components of network management, which can effectively improve network availability, shorten network failure time, help improve network performance, satisfy network service quality and ensure network security. This paper proposes a communication fault detection method based on the analysis of communication protocol message flow for POWERLINK, an industrial Ethernet protocol widely used in the field of industrial communication at present. By monitoring network status and building fault judgment logic, it can analyze the rationality of message sequence and protocol consistency in the message flow so as to effectively detect the dynamic upper layer protocol fault in the network and determine the location of the fault. In order to verify the effectiveness of this method, we designed a POWERLINK network communication fault diagnosis system, which can correctly identify and analyze the wrong data frame sequence in the data message flow and finally achieve the diagnosis and location of POWERLINK network communication fault.

“…In this paper, a method for blade dynamic strain measurement with an FBG sensor in helicopter flight is presented and an FBG dynamic strain measurement system for the rotor blade of a helicopter in real flight is established. The strain data transmission on the rotor hub to the cabin is achieved by upper and lower communication modulation units with power line communication (PLC) technology [ 13 ]. Orthogonal frequency-division multiplexing (OFDM) [ 14 ] modulation technology is adopted to eliminate the effects of the helicopter’s electromagnetic environment on electrical sensing components.…”

Fiber Bragg grating (FBG) sensor has a lot of advantages over the resistance strain gauge and has been used in many applications. However, there are few applications of rotor blade dynamic measurement in helicopter flight. In this paper, a method for blade dynamic strain measurement using an FBG sensor in a helicopter’s real flight is presented. The corresponding measurement system is established and can eliminate the effects of the helicopter’s electromagnetic environment on the electrical sensing components in the measurement system with the orthogonal frequency-division multiplexing modulation. The measured dynamic strains on the rotor blades of the helicopter in real flight contain six harmonic frequencies with the vibration characteristics of rotor blades, indicating that the established FBG measurement method and system have practical engineering applications.
