The vision-based smoking detection algorithm plays a key role to prevent a fire in grid facility environment. However, traditional methods based on target detection remain challenging in the realistic scenario, such as that it can not correctly distinguish whether a tiny object is a cigarette. In this paper, based on human geometric constraints(HGC), we propose a method which combines action recognition and target detection. First, in order to remove irrelevant action frames, we extract human skeletal key points from relevant frames using HGC algorithm, and build a smoking action dataset. Second, we train a neural network with the dataset of smoking action and then combine the deep learning-based target detection method to refine the judgment of smoking action with the bounding box extracted by skeletal points. Comprehensive experimental results demonstrate that our proposed method removes about 90% interfering action frames, improves average precision of the network from 77% to 82% in our dataset.","PeriodicalId":153030,"journal":{"name":"2021 3rd International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122685979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the traditional centralized optimization scheduling has problems such as large transmission requirements and low computational efficiency. A distributed optimal scheduling model of AC/DC HDN is put forward on the basis of the alternating direction multiplier method (ADMM). The internal coupling relationship of AC/DC HDN adopting the voltage source converter (VSC) is analyzed, and it is decomposed into the AC subsystem, DC subsystem, and VSC subsystem, correspondingly. Aiming at these three subsystems, with the goal of the lowest economic operation cost, a distributed optimization operation model is established respectively, and the alternate iterative solution is performed based on ADMM. Finally, based on the topology structure of the IEEE 33-node example system, related examples are designed to simulate and verify the proposed distributed optimal scheduling of the AC/DC HDN.","PeriodicalId":153030,"journal":{"name":"2021 3rd International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116097525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed algorithm is based on the pilot signal, which consists of several training sequences with a good autocorrelation characteristic, such as Barker sequence, pseudo-noise (PN) sequence, etc. By measuring the correlation peak(s), the carrier phase and its change rate at assigned time interval can be derived, as well combined with the over-sampling process at thereceiver side, a near optimal sampling timing can be determined. Depending on the structure of the pilot signal as well the range of the carrier frequency offset (CFO), the carrier phase increment can be derived through one training sequence or two identical sequences. In turn the carrier phase frequency offset estimation can be derived by the measured phase increment. The scheme can be applied in wide range of wireless communication systems, especially for moderate data transmission.","PeriodicalId":153030,"journal":{"name":"2021 3rd International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131479982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is widely used in industrial production. However, the control strategy of SRM and the corresponding hardware and software are the key to ensure its high-quality operation. In this paper, the power converter is designed as a three-phase inverter bridge circuit and adopts a unique symmetrical and uneven excitation mode of 720 º electrical angle one cycle. The hardware and software system of closed-loop control based on AT89C52 single chip microcomputer and speed detection signal is further designed. The excitation sequence of each phase winding is controlled by the main switch circuit through PI regulation and PWM technology, The speed regulation control of SRM is realized.

Problems in recent researches exist such as manual feature extraction lacks transferability and interpretability, and deep learning methods rely too much on object recognition performance. Therefore, a defect detection framework is proposed based on Mask RCNN network and temporal-spatial similarity calculation. The implementation process is to first extract features of original pictures which are used to detect objective equipment position. Then the possible defect region is given by maximum gray level gradient. It is finally determined by temporal-spatial similarity between possible defect equipment and normal equipment of the same kind. Experiments show that, compared with other popular methods, the proposed framework takes multi-factor similarity into consideration, and therefore has a much better precision, bringing a new idea to automatic power equipment inspection.","PeriodicalId":153030,"journal":{"name":"2021 3rd International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120941578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two factors causing the scarcity of accurate distribution network topology and parameters. Firstly, with lots of distributed equipment attached, the distribution network changes topology frequently. Secondly, the amount of monitoring equipment is limited. However, inferring the correct network topology through historical operating data becomes possible crediting to data-driven technology. Current identification methods require full sets of measurements. Unfortunately, actual measurements are generally incomplete and are from various sources. Data sets with this property are defined as diverse measurement data in this paper. Driven by diverse measurement data, a distribution network topology identification algorithm is proposed. Regression method and the branch power flow equation are employed to perform the identification. The analysis of IEEE 7-node and 33-node networks shows that accurate topology identification results are achieved, which indicates the algorithm proposed is robust and suitable for a variety of identification scenarios.","PeriodicalId":153030,"journal":{"name":"2021 3rd International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117154262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
