In order to improve the secure transmission capability of terminal upgrade files, we proposed a secure transmission method of terminal upgrade files based on dynamic encryption key. This method realized the access control of terminal upgrade file by using no proxy key publishing protocol, designed the dynamically symmetric key for the terminal upgrade file. The encoding calculation of terminal upgrade files in the process of secure encryption is carried out based on bilinear mapping method. We scrambled and rearranged the terminal upgrade files according to the intensity of plaintext attack, then adopted the random linear coding method to encrypt the terminal upgrade files by dynamic symmetric key and realize the secure transmission for the files. Simulation results show that this method can effectively improve the security transfer performance of upgrade files, and can meet the requirements of current business applications. © 2019 IEEE.

In order to minimise the delay of data aggregation scheduling, a task classification aware data aggregation scheduling algorithm is proposed. Through the multi-power and multi-channel approach of sensor nodes, maximum independent sets are used to construct network topology structure based on data aggregation backbone tree. According to the scheduling priority, the data aggregation scheduling within clusters is achieved by approximating the greedy algorithm. Besides, combined with sparse coefficient, sensing task type reduces the amount of data transmission, and then the level of cluster head nodes in the network is used to achieve data aggregation scheduling between clusters. Numerical results show that the proposed algorithm can reduce cluster heads data traffic and energy consumption, while shortening the data aggregation delay and enhancing the network survivability. © 2019 Inderscience Enterprises Ltd.

Aiming to explore the passive micro sensor for SF6 detection, the proposed method is about designation and structure of SF6 detection micro sensor with high signal-to-noise ratio, miniaturization and passivity. Advanced micro-machining technology is presented to sharply reduce the volume of the sensor, where the volume can be reduced by more than 50% compared with the existing sensor with discrete combination. The cost and volume reduction does not only make the new detection equipment possible, but the energy consumption of the whole system will also be greatly reduced. The application and promotion of the passive micro sensor in ring network cabinet, GIS, GIL and cable channel can bring considerable economic benefits. © 2019 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.

Real-time database (RTDB) is a memory database system which requires very high real-time, stability, accuracy and consistency. RTDB is responsible for real-time data collection, data storage, data computing and other data services in a power plant distributed control system (DCS). Therefore, the design quality of the RTDB system is crucial to the development of the entire DCS system. Strict integration testing is one of the important means to ensure the design quality of the power plant DCS RTDB interface, but the traditional database integration testing method is difficult to balance test efficiency and test accuracy. In this paper, a combination integration test method is established for the particularity of RTDB interface design. And through the test of specific projects, it is verified that this method can effectively shorten the testing time under the premise of ensuring the accuracy of the test.

Real-time database (RTDB) is an important part of the distributed control system (DCS), which is equivalent to a data processing center and functions as a data exchange area. The RTDB kernel carries the main features of the RTDB, supports task timing constraints, maintains a large amount of shared data, and ensures the integrity, consistency and real-time performance of the data. It also provides data access services for historical databases and human-computer interaction client programs, and is a bridge for data interaction between controllers and clients. The data in the real-time library is stored in memory. Therefore, the design of the RTDB memory structure directly affects the quality of the entire DCS system. © 2019 IEEE.

In the power industry, there are a lot of image and video data need to be analyzed to find out equipment abnormalities such as bolt looseness and out of stock. Using artificial intelligence technology for image analysis can reduce the artificial dependence, but the general object detection algorithms, such as SSD, can not get a good detection effect for small targets. In this paper, we proposed an improved SSD object recognition algorithm to improve the recognition accuracy of small targets, based on the characteristics of power image recognition requirements. The method can improve the ability of SSD framework to understand small objects and enhance the location information and semantic information of the small targets. The method introduce the deconvolution structure to act on the shallow feature layer Conv4-3 and then use pooling layer to get the fixed size. Finally the method made Conv14 upsampled to the same size, and make full use of the information of small targets. Experimental results show that the proposed method can achieve the good recognition accuracy. © 2019 IEEE.

In 2019, the state grid Corporation of China proposed that the important material basis for building a worldclass energy Internet enterprise is to build and operate "two networks" (ie, "Ubiquitous power Internet of Things" and "Strong Smart grid"). The construction of "two networks" requires the support of a large number of terminal devices, and all devices need to complete the functions of automatic data collection and calculation. The implementation of these functions is inseparable from the support of the chip. The layout design of integrated circuits is one of the key steps in chip design. A good layout design can effectively optimize the chip area, reduce the cost of the chip, and help improve the chip performance. This article will use our company's finished chip layout design examples to explain how to achieve high security, low power consumption, high integration and low cost of power security chip from the levels of chip module layout and chip overall layout. © 2019 IEEE.

By acquiring the location information of the mobile target using the location estimation algorithm based on the wireless sensor network, human life in the substation and the safe operation of the mobile device can be protected, and the intelligent management of the mobile target in the substation can be realized. This is of great significance for realizing the intelligence and informationization of substation management. The environment in the substation is complex and there is Non Line of Sight (NLOS) propagation. In view of the large error in the results of the existing mobile position estimation algorithm in the NLOS environment, this paper proposes an error probability localization algorithm suitable for substation. The simulation results show that the proposed algorithm has higher positioning accuracy than the existing algorithms. © 2019 IEEE.
