If heat dissipation measures are not taken in time, the accumulated heat will have a great impact on the battery temperature rise, seriously causing some battery safety incidents. To solve the cooling problem of lithium-ion batteries during charging and discharging cycle, in this paper, a square cooling module of lithium-ion power battery with phase change material (PCM) was designed, whose heat production and heat dissipation were established, which were coupled with the air-cooling heat dissipation model. Finally, a two-dimensional active and passive heat dissipation model of lithium battery module was formed, based on the thermal model, the simulation module in ANSYS Fluent was made use of simulating the thermal dissipation characteristics. The simulation results show that when the coefficient of convective heat transfer is 12, 60, 120W/(m2·K), the highest temperature of the battery module is 142.8℃, 74.6℃, 41.9℃, respectively, which indicates that the coefficient has an important influence on its maximum temperature. Secondly, during the whole charging-discharging cycle, its maximum temperature is 82.2℃, 79.1℃, 77.7℃and 75.1℃, respectively, when the standing time is 0, 5, 10 and 20min. Obviously, increasing the standing time can reduce its maximum temperature. In addition, the continuous heat accumulation will lead to the failure of PCM, at this time, the PCM needs to be coupled with other cooling technologies such as forced air cooling.","PeriodicalId":187064,"journal":{"name":"Proceedings of the 3rd Asia-Pacific Conference on Image Processing, Electronics and Computers","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121002443","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}

China’s engineering cost industry has been severely challenged, and the previous management methods have been difficult to meet the requirements of the times. The superiority of data mining technology based on statistical analysis is becoming more and more obvious. Data mining is a new and promising field gradually formed as the application research of database and data warehouse. The project cost management department needs to record more and more project cost data, which requires the introduction of data mining based on statistical analysis. Data mining realizes the functions of establishing database, data purification, data query and sharing, analysis and early warning in project cost management. In practical application, data screening can also be carried out by selecting factors such as project unilateral cost index, cost reduction rate, completion settlement price, project structure form and so on. This paper focuses on its application advantages in project cost management.","PeriodicalId":187064,"journal":{"name":"Proceedings of the 3rd Asia-Pacific Conference on Image Processing, Electronics and Computers","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115253693","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}

From the perspective of multiple linear regression and Lingo’s multi-objective programming models, the decision-making model follows the \"safety first\" principle and the principle of minimum cost in the organization, dispatch, and distribution of power grid companies. And according to the load forecast and transaction rules, the optimal power distribution scheme can be designed for the power personnel. The research results show that the difference in load demand leads to different transmission congestion principles and cost settlement methods. Therefore, this paper divides the forecast load demand into three intervals (0,982.9136], (982.9136,1094.500], (1094.500,+ ∞ ], the simulation test was carried out. When the forecasted load demand for the next period is 984.2MV and 1052.8MV, LINGO and MATLAB software are used to solve the deployment mentioned above plan model according to the transmission congestion management principle to obtain the adjusted units. And find the blocking cost is 18232.2 yuan and 22506 yuan.","PeriodicalId":187064,"journal":{"name":"Proceedings of the 3rd Asia-Pacific Conference on Image Processing, Electronics and Computers","volume":"442 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116151159","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}

Macroeconomic forecasting and decision-making is an important research direction in the field of management science, and an important problem that must be solved in regional and national economic development planning and decision-making. By using the self-learning, self-adapting and nonlinear characteristics of BPNN (BP neural network), economic data analysis and intelligent prediction can be realized. By establishing the evaluation index system of economic system, the data of economic variables are normalized, and then sent to BPNN for training to get the corresponding parameters before prediction. In this paper, PCA (principal component analysis) algorithm and BPNN algorithm are combined, and the PCA algorithm's advantage of dimension reduction and neural network's advantage of nonlinear expression are fully utilized, and the PCA-BPNN prediction model is established, and the algorithm is applied to the analysis of social fixed assets investment data. Compared with the linear prediction method, it is found that PCA-BPNN prediction algorithm has better effect.","PeriodicalId":187064,"journal":{"name":"Proceedings of the 3rd Asia-Pacific Conference on Image Processing, Electronics and Computers","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122182510","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}
