AbstractThe paper introduces a handheld integrated power data acquisition and analysis equipment based on a computer wireless network mobile platform, an intelligent transportation inspection box. The intelligent transportation inspection box acts as a bridge between the transportation inspection work site side and the power grid company center to realize data and resource sharing between the site and center sides. The application of intelligent operation and inspection boxes based on computer wireless network integration technology is essential for improving the professional and intelligent level of on-site operation and maintenance, improving the efficiency of operation and inspection work and the ability to control equipment status, strengthening state maintenance and auxiliary decision-making, and promoting the construction of smart grids significance.

Routing Method

It is a significant issue for network carriers to immediately restore telecommunication services when a disaster occurs. A wired and wireless network cooperation (NeCo) system was proposed to address this problem. The goal of the NeCo system is quick and high-throughput recovery of telecommunication services in the disaster area using single-hop wireless links backhauled by wired networks. It establishes wireless bypass routes between widely deployed leaf nodes to relay packets to and from dead nodes whose normal wired communication channels are disrupted. In the previous study, the optimal routes for wireless links were calculated to maximize the expected physical layer throughput by solving a binary integer programming problem. However, the routing method did not consider throughput reduction caused by sharing of wireless resources among dead nodes. Therefore, this paper proposes a nonlinear bypass route computation method considering the wireless resource sharing among dead nodes for the NeCo system. Monte Carlo base approach is applied since the nonlinear programming problem is difficult to solve. The performance of the proposed routing method is evaluated with computer simulations and it was confirmed that bandwidth division loss can be avoided with the proposed method.

Abstract The manual inspection for the damage state of the electric energy metering box consumes a lot of time, the workload is large, and the data storage is difficult. In order to solve these problems, this paper proposes an automatic detection method for the damage state of the electric energy metering box based on the YOLOv5 algorithm. The actual metering box pictures taken by the operation and maintenance inspectors are used as the training set, LabelImage is used to annotate the data set, and YOLOv5s model is used to train the data set. The experimental results show that the method proposed in this paper can accurately mark the position of the metering box lid and accurately predict its damage state. The average accuracy reaches 98%, which can meet the requirements for the detection accuracy of the power metering box damage state in the operation and maintenance inspection work.

Hybrid Wireless Network

The objective of the Hybrid Wireless Network with dedicated Relay Nodes (HWN*) proposal is to interface the Base Station (BS) Oriented Mobile Network (BSON) and the 802.11X assisted Mobile Ad hoc Wireless Network (MANET) so that one system can be utilised as an alternative radio access network for data transmissions, while the incorporation of the Relay Node (RN) is to extend the communication coverage, optimise medium resource sharing, increase spatial reuse opportunity, stabilise MANET link and create more micro-cells. The HWN* keeps the existing cellular infrastructure and a end-user Mobile Terminal (MT) can borrow radio resources from other cells through secured multi-hop RN relaying, where RNs are placed at pre-engineered locations. The main contribution of this work is the development of a HWN* system framework and related medium access and routing protocols/algorithms. The framework dedicatedly addresses the transparent multiple interface traffic handover management, cross layer routing, RN positioning and network topology issues to increase communication system capacity, improve Quality of Service (QoS), optimise transmission delay and reduce packet delivery delay.

Vehicle will be connected to the Internet as both for ubiquitous remote controlling and as a means to meet Intelligent Transportation Systems (ITS) needs. At first, a gateway system between Controller Area Network (CAN) and IPV6 is required to connect vehicles to the Internet. Then this paper achieves the access of vehicle information and the control of vehicle using the CDMA wireless network based on the gateway. Finally, according to the result of the test, we have verified the correction and effectiveness of the control system.
