由于工业排放对城市造成大气灰霾复合型污染,需要进行工业排放控制。对工业排放进行控制时,需要根据记录的实时工业排放量不断调整控制策略,但传统极大似然法是根据当前工业排放量进行控制,不能对实时工业排放量进行跟踪,存在工业排放控制误差大的问题。提出一种基于数学分析的工业排放控制优化方法。先利用数学分析方法以工业排放控制过程中价值最大化为导向,组建工业排放支持向量机数学模型,在此基础上,融合于流量数据的预测控制算法实时跟踪工业排放量,并协调控制的工业排放量,依据工业排放量动态变化适时调整控制目标,促使工业排放系统避免了由于污染物溢出造成大气灰霾,实现了对工业排放控制优化。仿真结果证明,采用数学分析的工业排放控制优化方法对工业排放污染处理系统的设计与运行管理具有重要的指导意义。  相似文献

绿色,象征的生机;绿色,象征着朝气,绿色,象征着健康。为了使青山依旧葱郁,为了使碧草依然嫩绿,为了使大树如故苍翠,为了保护我们赖以生存的资源,全球都在大力倡导"绿色产业"的理念。作为能源消耗大户的中国,更是不能落后!我国是人口众多的发展中大国,资源相对不足,许多资源的人均拥有量远低于世界平均水平。同时,资源利用效率较低,污染排放较严重,单位产值能耗明显高于世界平均水平。为此,国家大力实施节能减排全民总动员的战略方针。十一五规划明确规定了能耗降低20%和主要污染物排放减少10%的节能减排目标。而国内的耗能大户主要集中在央企,分布在石油石化、煤炭、化工、冶金、电力、运输、建材等领域。据悉,中央石油石化企业能源消耗占全国的5.8%,冶金企业紧随其后占全国的2.9%。于是,在国内各个行业领域都先后提出了绿色投资、绿色战略的同时,作为高能耗、高消耗产业的冶金行业也悄然兴起了"绿色生产"的洪流。作为自动化的专业媒体,我们将对此持续关注。  相似文献

Though cooperation in environmental control holds out the best promise of effective actions, limited success has been observed because existing multinational joint initiatives fail to satisfy the property of subgame consistency. A cooperative solution is subgame consistent if the solution optimality principle is maintained in any subgame which starts at a later time with any feasible state brought about by prior optimal behaviors. This paper presents a cooperative stochastic differential game of transboundary industrial pollution with two novel features. The first feature is that industrial production creates short-term local impacts and long-term global impacts on the environment. Secondly, a subgame consistent cooperative solution is derived in this stochastic differential game together with a payment distribution mechanism that supports the subgame consistent solution. This is the first time that pollution management is analyzed in a cooperative stochastic differential game framework under these novel features.  相似文献

针对工业热污染区提取准确率低、误差大及遗漏率高等问题,提出一种基于八分位法的工业热污染区提取方法。即首先基于改进的单通道算法获得地表温度,其次采用八分位法提取高温异常区,通过叠加建筑用地,得到疑似工业热污染区。然后,以彩钢房为判断标准,利用Google Earth影像进一步提取工业热污染区。通过对比分析热岛强度(HI)、改进的箱线图和八分位法3种方法的精度差异,发现潜在热异常是导致结果降低的主要因素。其中,热岛强度和改进的箱线图法均受到人类活动影响,提取的工业热污染区中居民区和商业区所占比例不小于工业区,误判率较高,八分位法提取精度最高,效果更佳,且从一定程度上避免了潜在热异常带来的影响。为验证结果精度,随机选取10%的工业热污染区像素点作为验证点,经Google Earth核实,发现利用八分位法提取的工业热污染区精度均在70%以上,最高可达92%。因此,八分位法提取工业热污染区简单有效,结果准确可靠,能够避免目标区内潜在热异常的影响,能够为环境保护、工业去产能监测提供技术支撑服务。  相似文献

Aiming at the problems of low accuracy, large error and high omission rate in the extraction of industrial thermally polluted areas, an extraction method for industrial thermally polluted areas based on the octant method was proposed. That is, firstly, the surface temperature is obtained based on the improved single-channel algorithm, and then the high temperature anomalous area is extracted by the octet method, and the suspected industrial thermal pollution area is obtained by superimposing the building land. Then, using the color steel room as the criterion, Google Earth images were used to further extract the industrial heat-polluted areas. By comparing and analyzing the difference in accuracy of the three methods of Heat Island intensity (HI), improved boxplot, and octave method, it is found that the potential thermal anomaly is the main factor leading to the reduction of results. Among them, the intensity of the heat island and the improved box plot method are affected by human activities. The proportion of residential and commercial areas in the extracted industrial thermal pollution area is not less than that of the industrial area, and the false positive rate is high, The effect is better, and the impact of potential thermal anomalies is avoided to a certain extent. In order to verify the accuracy of the results, randomly selected 10% of industrial thermally polluted pixels were used as verification points. After verification by Google Earth, it was found that the accuracy of the industrial thermally polluted areas extracted by the octave method was more than 70%, up to 92%. Therefore, the octave method is simple and effective for extracting industrial thermally polluted areas, and the results are accurate and reliable. It can avoid the potential thermal anomalies in the target area, and can provide technical support services for environmental protection and industrial capacity reduction monitoring.  相似文献

This paper introduces a model and corresponding software for modeling China's Energy Requirements and the CO2 Emissions Analysis System (CErCmA). Based on the input–output approach, CErCmA was designed for scenario analysis of energy requirements and CO2 emissions to support policymakers, planners and others strategically plan for energy demands and environmental protection in China. In the system, major drivers of energy consumption are identified as technology, population, economy and urbanization; scenarios are based on the major driving forces that represent various growth paths. The input–output approach is employed to compute energy requirements and CO2 emissions under each scenario. The development of CErCmA is described in a case study: China's energy requirements and CO2 emissions in 2010 and 2020 are computed based on the input–output table of 1997. The results show that China's energy needs and related CO2 emissions will grow exponentially even with many energy efficiency improvements, and that it will be hard for China to maintain its advantage of low per capita emissions in the next 20 years. China's manufacturing and transportation sectors should be the two major sectors to implement energy efficiency improvements. Options for improving this model are also presented in this paper.  相似文献

As communication technology and smart manufacturing have developed, the industrial internet of things (IIoT) has gained considerable attention from academia and industry. Wireless sensor networks (WSNs) have many advantages with broad applications in many areas including environmental monitoring, which makes it a very important part of IIoT. However, energy depletion and hardware malfunctions can lead to node failures in WSNs. The industrial environment can also impact the wireless channel transmission, leading to network reliability problems, even with tightly coupled control and data planes in traditional networks, which obviously also enhances network management cost and complexity. In this paper, we introduce a new software defined network (SDN), and modify this network to propose a framework called the improved software defined wireless sensor network (improved SD-WSN). This proposed framework can address the following issues. 1) For a large scale heterogeneous network, it solves the problem of network management and smooth merging of a WSN into IIoT. 2) The network coverage problem is solved which improves the network reliability. 3) The framework addresses node failure due to various problems, particularly related to energy consumption. Therefore, it is necessary to improve the reliability of wireless sensor networks, by developing certain schemes to reduce energy consumption and the delay time of network nodes under IIoT conditions. Experiments have shown that the improved approach significantly reduces the energy consumption of nodes and the delay time, thus improving the reliability of WSN.   相似文献
