In the actual printing process, the quality of printed products is often affected by many factors such as printing technology, equipment and environment. In some cases, it may cause printing defects in printed product. Product with printing defect need to be removed to ensure product quality. This paper proposes a deep learning method for printing defect detection. This method can classify printing defects into five categories. The experimental results show that the accuracy, precision and recall rate of the proposed printing defect detection method are all above 96%.

With the rapid growth of load and the gradual implementation of the power market, the traditional centralized power generation gradually exposes the disadvantages such as large investment, long construction cycle, inflexible adjustment and high accident rate. To solve these problems, distributed power generation has received wide attention. Based on the situation of distributed power generation user in Liaoning, the cause of why distributed power generation accuracy is low is found out, the influence factors of power generation accuracy are demonstrated and the measurement method of low voltage distributed photovoltaic power generation are further analyzed. The main reasons of distributed power generation accuracy are the a long time of troubleshooting cycle on field, the data transmission rate is slow, and the marketing system file lags behind. Aiming at these problems, the marketing system “triple” regulatory function is added, the relay communication technology is applied, and file key link “three synchronous” control mechanism is established to make a new measurement method. After a lot of practical application, the photovoltaic power generation accuracy is successfully improved, thus the distributed power generation accuracy is greatly improved.

Honeywords are decoy passwords placed in user’s account to detect whether password files are leaked. The distinguishing attack of honeywords plays a very important role in evaluating the strength of honeywords. However, the existing attack methods cannot simulate the ability of the attacker, leading to inaccurate evaluation of honeywords strength. In this paper, we propose an adaptive distinguishing attack method ANB-PW to construct a Naive Bayes classifier based on passwords and honeywords. In addition, ANB-PW uses guessed passwords to adjust its guessing strategy in real time. Our results suggest that compared with Top-PW and PCFG, ANB-PW has better attack ability.

A method that can identify the rotational inertia in a timely manner is proposed because the performance of a permanent magnet synchronous motor servo system is easily affected by the rotational inertia. Firstly, principles of model-referenced adaptive recognition algorithm is introduced, and the influence of the adaptive gain on the identification results is analyzed. Then, design a suitable range of adaptive gain value, use the set error value to compare the identification error with the set value, and then select the appropriate gain for identification. Finally, through simulation verification, this method has fast identification convergence speed, high precision and strong anti-disturbance.

According to the current transaction rules of power peak shaving auxiliary service, the comprehensive benefits of regional power grid after wind power consumption capacity is improved, and the comprehensive evaluation index of regional power grid comprehensive benefit based on entropy weight method is established. Considering the uncertainty of wind power and the cost of paid peak-shaving auxiliary service, an evaluation model of regional power grid’s comprehensive benefits is established based on the holistic model method. The proposed model was simulated and verified by example tests. The analysis of example results shows that compared with the alternative scheme, the scheme with electrode electric boiler on the power supply side can improve the wind power consumption capacity of the regional power grid, provide sufficient flexibility for the system, and effectively improve the comprehensive benefits of the power supply side of the regional power grid.

With the popularity of GPS and other positioning technologies, people are increasingly aware of the importance of positioning technology. However, due to poor indoor GPS signal and complex environment, many indoor positioning schemes are not ideal. Bluetooth, with its open global specification, has been widely used in all fields with the advantage of extremely low cost. With the release of Bluetooth 5.0, the power consumption and communication rate of low power devices have been greatly improved, and the anti-interference performance has also been optimized. All of these enhancements open up many location technology possibilities for Bluetooth 5.0. Direction Finding was added to the Bluetooth 5.1 standard, which is one of the possibilities of indoor positioning utilization. This paper focuses on the direction finding function of Bluetooth 5.1, discusses the principle of direction finding using Bluetooth, and some of experiments are designed to verify the algorithm.

It will cause serious casualties for passengers, if the traction wire rope is broken in frequent accidents about elevator, therefore, it is very important to monitor whether the traction wire rope is broken in real time. This paper proposes a method to Monitor whether the elevator’s traction wire rope is broken by the detection algorithm of CCD vision. Collect the image information of the traction wire rope in real time through the CCD camera, and it is for the collected image through performing median filtering, the segmentation of binarization threshold, and the edge extraction of Canny operator and we can obtain the edge information of the traction wire rope through the axis’s projection algorithm or the area Difference algorithm, and it will compare the calculated result with the standard error. The traction wire rope is working normally when the comparison result does not exceed the value of allowable error, otherwise it is judged that the traction wire rope is broken. Experimental results show that the algorithm can detect Whether the elevator’s traction wire rope is broken in real time.
