With the in-depth development of “two integration”, industrial control network security situation is more and more serious, industrial control network security protection work is more and more important. Aiming at the characteristics of sparse and complex dimensions of industrial control network security data, combining with the conceptual model of network security situation awareness, this paper proposes a network security situation assessment method, which uses stack self-encoder to process sparse data and uses radial basis neural network to fit complex nonlinear characteristics. It effectively extracts the data features, realizes the analysis and understanding of the data, and completes the security situation assessment, which provides a new method for the security situation assessment of the industrial control network.

The detection and recognition of stacked workpieces is affected by workpiece occlusion and workpiece overlap, which leads to the problem of difficult detection of workpiece types. This paper proposes a detection method based on the improved Faster R-CNN model, improves the Faster R-CNN feature network, and selects ResNet combined with SENet for feature extraction, which improves the important feature layer and suppresses the non-important feature layer. Introduce the Soft-NMS algorithm to optimize the NMS algorithm to reduce the problem of missed detection and false detection of overlapping or adjacent targets. The test results show that compared with the unimproved Faster R-CNN model, the improved Faster R-CNN model outperforms the traditional algorithm in terms of accuracy, precision, recall and F1 value.

Taking stm32f407 single chip microcomputer as the control core, combined with STM32F103 single chip microcomputer, openmv and k210, the device is designed to be used for drug transportation in wards and isolation wards with large workload in the hospital. The device uses openmv to identify the red solid line on the transportation ground of the hospital, Through the dynamic priority scheduling algorithm in PD algorithm, the priority of tasks is dynamically allocated according to the resource requirements of tasks, so as to have greater flexibility in resource allocation and scheduling, realize flexible tracking function and dynamic adjustment process, and make the car drive along the red. K210 visual module is used to reflect the appearance difference through the given training photos, which is as same as the identification number as possible, which is convenient to improve the identification rate. After more identification times, the identification number and its position information can be accurately identified, and the identified number and its position information can be transmitted to stm32f407 single chip microcomputer through serial port communication (considering the need to identify four numbers at the same time, two k210 are installed on the front of each vehicle), stm32f407 single chip microcomputer processes the identification information of k210 and tells STM32F103 single chip microcomputer the movement state of the car at this time through serial port communication. Finally, STM32F103 single chip microcomputer controls the car to move accordingly. The data interaction method of the two cars adopts wireless communication. The system has the advantages of short recognition time, digital recognition accuracy of up to 90% and good stability. It can better complete the drug delivery work required by hospital medical staff, and the work efficiency is higher than manual work. At the same time, the machine itself can also cut off the direct contact between medical staff and patients, which can greatly reduce the number of contact between medical staff and patients, Reduce the prevalence of cross infection and medical staff. The device adopts a multi-level priority scheduling algorithm to assign a priority to each process. During each process scheduling, the scheduler always schedules the task with the highest priority to execute, so as to make the car movement more flexible and more active. It is convenient to deal with some emergencies by using interrupts, which is more reasonable and suitable for real hospital medical work.
本系统由STM32F407单片机、STM32F103单片机、openmv视觉模块和k210视觉模块组成。本装置以stm32f407单片机为控制核心,结合STM32F103单片机、openmv和k210,设计用于医院病房和隔离病房工作量较大的药品输送。该装置采用openmv识别医院运输地面上的红色实线,通过PD算法中的动态优先级调度算法,根据任务的资源需求动态分配任务的优先级,从而在资源分配和调度上具有更大的灵活性,实现灵活的跟踪功能和动态调整过程,使小车沿红色行驶。使用K210视觉模块,通过给定的训练照片反映外观差异,尽可能与识别号一致,方便提高识别率。经过多次识别后,可以准确识别出识别号码及其位置信息,并通过串口通信将识别的号码及其位置信息传输到stm32f407单片机(考虑到需要同时识别4个号码,每辆车前方安装2台k210),stm32f407单片机对k210的识别信息进行处理,并通过串口通信告诉STM32F103单片机此时汽车的运动状态。最后由STM32F103单片机控制小车进行相应的运动。两车的数据交互方式采用无线通信。该系统具有识别时间短、数字识别精度可达90%以上、稳定性好等优点。能较好地完成医院医务人员所需的给药工作,工作效率高于人工。同时,机器本身还可以切断医护人员与患者之间的直接接触,可以大大减少医护人员与患者之间的接触次数,减少与医护人员交叉感染的流行。设备采用多级优先级调度算法,为每个进程分配优先级。在每次调度过程中,调度程序总是调度优先级最高的任务执行,从而使汽车运动更灵活、更活跃。利用中断处理一些突发事件比较方便,比较合理,适合真正的医院医疗工作。

Butanol and C4 olefins, as important chemical raw materials, are widely used in the production of chemical products and pharmaceutical intermediates. Traditional production methods use fossil energy as raw materials, but with the shortage of fossil energy production and the aggravation of its impact on the environment, the energy supply gradually tends to be diversified, and the development of new clean energy is becoming more and more urgent. Ethanol molecules can be prepared by biomass fermentation. They have a wide range of sources and are green and clean. They are used as platform molecules to produce high value-added butanol and C_4 olefins have great application prospects and economic benefits, and have attracted extensive attention at home and abroad. However, in the current industrial production, the catalyst combination and temperature have a great impact on the conversion of ethylene and the selectivity of C4 olefins, and its selection and control greatly affect the production efficiency of C4 olefins. This paper focuses on the influence effect and degree of two factors on two dependent variables in the process of preparing C4 olefins by ethylene coupling reaction. By establishing the least square curve to fit the temperature and ethanol conversion and the temperature and C4 olefin selectivity, the fitting curve is obtained. It can be seen that the temperature has a primary or quadratic function relationship with the ethanol conversion or C4 olefin selectivity, so it is judged that it has a certain influence, Then the effects of temperature, catalyst group and loading method on ethanol conversion and C4 olefin selectivity were obtained by Spearman correlation coefficient and random forest regression algorithm. Based on this result, the model is established, optimized and analyzed, and the optimal catalyst combination and temperature are obtained, so as to obtain the highest C4 olefin yield and achieve the maximum industrial benefit
丁醇和C4烯烃作为重要的化工原料,广泛应用于化工产品和医药中间体的生产。传统的生产方式以化石能源为原料,但随着化石能源生产的短缺及其对环境影响的加剧,能源供应逐渐趋向多样化,开发新型清洁能源的需求越来越迫切。乙醇分子可以通过生物质发酵制备。它们有广泛的来源,是绿色和清洁的。它们作为平台分子用于生产高附加值的丁醇和C_4烯烃,具有很大的应用前景和经济效益,引起了国内外的广泛关注。但在目前的工业生产中,催化剂的组合和温度对乙烯的转化率和C4烯烃的选择性影响很大,其选择和控制对C4烯烃的生产效率影响很大。研究了乙烯偶联反应制备C4烯烃过程中两个因素对两个因变量的影响作用和程度。通过建立最小二乘曲线拟合温度与乙醇转化率、温度与C4烯烃选择性,得到拟合曲线。可以看出,温度与乙醇转化率或C4烯烃选择性呈一次或二次函数关系,因此判断温度对乙醇转化率和C4烯烃选择性有一定的影响,然后通过Spearman相关系数和随机森林回归算法得到温度、催化剂基团和负载方式对乙醇转化率和C4烯烃选择性的影响。在此基础上,建立模型并进行优化分析,得到最佳催化剂组合和温度,以获得最高的C4烯烃收率,实现最大的工业效益

A Classification Model for Unbalanced Power Traffic 不平衡电力流量的分类模型
Pub Date : 2022-02-01 DOI: 10.1109/ICTech55460.2022.00026

With the continuous development of power grid informationization, the information security of the power grid is increasingly concerned. Grid traffic classification is an important basis for ensuring information security of the grid. In the process of realizing grid traffic classification, due to the different frequency of grid services and the increasing number of new services, it leads to problems such as unbalanced grid traffic data and dynamic traffic data, etc. The unbalanced traffic data causes the prediction accuracy of small categories to be much lower than the applicable standard, and the dynamic traffic data causes the model update to take a lot of time and resource overhead The dynamic traffic data causes the model update to take a lot of time and resource overhead. To solve these problems, a classification model for unbalanced dynamic grid traffic data (UDTCM) is proposed in this paper. The model uses the statistical characteristics of the flow data to detect the prediction accuracy of the classifier in time and avoid the prediction results from significantly degrading with the change of environment. Meanwhile, a resampling algorithm is used to correct the flow data to improve the data imbalance of grid flows and improve the prediction accuracy of small classes. The experimental results show that the model improves the classification of unbalanced grid flow data and reduces the time and resource overhead of model updates due to data updates.
随着电网信息化的不断发展,电网的信息安全日益受到人们的关注。网格流量分类是保证网格信息安全的重要基础。在实现网格流量分类的过程中,由于网格业务频次不同,新业务数量不断增加,导致网格流量数据不均衡、流量数据动态等问题。不平衡的流量数据导致小类别预测精度远低于适用标准,动态的流量数据导致模型更新花费大量的时间和资源开销,动态的流量数据导致模型更新花费大量的时间和资源开销。为了解决这些问题,本文提出了一种不平衡动态网格交通数据的分类模型。该模型利用流量数据的统计特征,及时检测分类器的预测精度,避免预测结果随着环境的变化而显著下降。同时,采用重采样算法对流量数据进行校正,改善网格流量数据的不平衡性,提高小类预测精度。实验结果表明,该模型改进了不平衡网格流数据的分类,减少了数据更新带来的模型更新时间和资源开销。

Grid traffic classification is an important basis for ensuring information security of the grid. In the process of realizing grid traffic classification, due to the different frequency of grid services and the increasing number of new services, it leads to problems such as unbalanced grid traffic data and dynamic traffic data, etc. The unbalanced traffic data causes the prediction accuracy of small categories to be much lower than the applicable standard, and the dynamic traffic data causes the model update to take a lot of time and resource overhead The dynamic traffic data causes the model update to take a lot of time and resource overhead. To solve these problems, a classification model for unbalanced dynamic grid traffic data (UDTCM) is proposed in this paper. The model uses the statistical characteristics of the flow data to detect the prediction accuracy of the classifier in time and avoid the prediction results from significantly degrading with the change of environment. Meanwhile, a resampling algorithm is used to correct the flow data to improve the data imbalance of grid flows and improve the prediction accuracy of small classes. The experimental results show that the model improves the classification of unbalanced grid flow data and reduces the time and resource overhead of model updates due to data updates.","PeriodicalId":290836,"journal":{"name":"2022 11th International Conference of Information and Communication Technology (ICTech))","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125897101","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}
