作者： S Ba Z B Hou D W Wang G Y Shi W H Zhang X J Han C Y Dong J J Liu State Grid Key Laboratory of Power Industrial Chip Design and Analysis Technology Beijing Smart-Chip Microelectronics Technology Co. Ltd Beijing Smart-Chip Semiconductor Technology Co. Ltd

This thesis presents a method that a position measurement method for moving targets is proposed based on the positioning method based on the time difference of arrival(TDOA) which is based on the research on the positioning problem of station inspection operators and equipment in complex working conditions. The probability error method is introduced to optimize the traditional positioning method that realizes the target node positioning by optimizing the distance difference between the target node to be located in the network domain environment and different base stations, which can effectively improve the positioning accuracy of staff and equipment in the station. Through experiments in a complex power frequency electric field environment, the test results show that the results calculated by the optimization method are better than the existing traditional positioning methods, and can effectively improve the positioning accuracy under the condition of line-of-sight, and realize the substation space Mobile target positioning to ensure the safety of operators.

power companies, the data collected by smart meters on electricity consumption is of vital interest. In 2019, Wang had a dispute with Ping Dingshan. They came into disagreement regarding the amount of electricity consumed, which was a difference of 1334 kWh. It was not settled until 2021. To avoid the above problem, smart meters could upload power information to the blockchain. In this paper, we improved the authentication protocol key proposed by Zhang and proposed a new scheme for uploading the power information from smart electricity meters, which ensures the integrity, confidentiality and authentication of the power information. At the same time, the proposed scheme is unbalanced for the computing capability of both communication parties, and can effectively reduce the burden of the server.

Identity-Based Cryptograph (IBC) takes the user's identity (such as email address, mobile phone number, personal name, etc.) as the public key, which reduces the process of exchanging digital certificates and public keys, effectively reduces the complexity of key and certificate management in the public-key system, and makes the security system easy to deploy and manage. It is very suitable for end-to-end offline secure communication, cloud data encryption, attribute-based encryption, policy-based encryption of various occasions. In order to improve the safety level of end-to-end off-line safety communication in electric vehicle pile sharing application and reduce the system complexity, this paper proposes an identity authentication system solution based on identification algorithm. © 2020 IEEE.

With the development of society, intelligent terminal equipment is used more and more widely. The use of intelligent terminals to locate children's position, to ensure that children are in a safe and controllable range, is more favored by parents. But now the smart watch needs to install the mobile phone card, which depends on the mobile phone traffic to locate, and the cost is relatively high. This paper proposes a Bluetooth low energy warning method to solve this problem. The distance between the two devices is calculated by the signal strength indication value received by the intelligent terminal, and then compare the preset received signal strength indication value with the received signal strength indication value, as well as the preset distance value and the calculated distance value of the two devices. When the received signal strength indication value is less than the preset value or the distance between the devices exceeds any of the preset values, the wireless device and the intelligent terminal will send an alarm at the same time to remind the two sides wearing the intelligent terminal and the Bluetooth device that the distance between the two sides has exceeded the safety value. The Bluetooth low energy warning method proposed in this paper has the characteristics of low cost and low energy consumption. © Published under licence by IOP Publishing Ltd.

In recent years, cyberspace security incidents have occurred frequently, and national and group cybersecurity threats have emerged. As the next-generation communication system, quantum security has to satisfy the security requirements. Also, it is especially important to build the fusion application of energy network quantum private communication technology and conventional network, and to form a safe and reliable quantum-level communication technology solution suitable for the power grid.

power distribution operation involves the supervision and control of the operating states of a large distribution power grid. This technology includes several features, e.g. an abundant amount of application nodes, diversity of communication channels, etc. To accelerate the construction of state grid-electric Internet of things and to guarantee the security of power grids data network and to consider the feature of power grids, a synthetic key management system is proposed. In the first section of this paper, from the perspective of maturity and practicality of related technology, the feasibility of combining quantum private communication and automatic power grid key management system is analyzed and demonstrated.

One of the most important performance index of UHF RFID tags is the operating distance, which can be extended by reducing the power consumption of RFID tags. In this paper, an RFID chip based on EPC Class -1 Generation-2/ISOIS000-6C protocol is presented. An optimization method for dynamic power consumption of clock tree in digital back-end design is proposed. This method can further reduce the dynamic power consumption for the completed layout. Under the condition of return frequency 170kHz, the simulated power consumption is reduced from 1. 4S3uW to 1. 357uW for the chip which was taped out with the TSMC 0. 18um process. © 2019 IEEE.

IEEE 802.15.4g Standard specifies multi-rate and multi-regional orthogonal frequency division multiplexing (MR-OFDM) physical layer, which supports principally outdoor, low-data-rate, wireless, smart metering utility network (SUN). Caused by Doppler frequency shift of fading channel, the inter-channel interference (ICI) arises in MROFDM system. In this paper, the degrading of performance due to ICI for detection of phase shift keying modulation signal is provided. It is derived that non-ideal properties for reception symbols are characterized by sampling offset and phase shift on subcarrier. Furthermore, the influence on data demodulation under different conditions is analyzed in detail. Simulation results are consistent with the theoretical analysis. © 2019 IEEE.
