The advent of the Second Industrial Revolution in the 1870s brought prodigious technological innovation that sparked the transition from the Malthusian economy—during which economic growth was directly coupled to population—to the birth of mass production and the modern linear economic model.Increased efficiency and productivity, along with unprecedented population growth, led to a cycle in which massive amounts of resources were utilized to manufacture products, which were then consumed and disposed of.While it has greatly enhanced individual incomes and the quality of life, the linear economic model has triggered the monumental degradation of the environment.

面对环境持续退化的威胁,正采取主动措施保护环境。日本有座城镇 引起人们的注意下川北端约200公里A bucolic burg best known as the hometown of world-class ski jumper Noriaki Kasai, Shimokawa has a population of only about 3,400 and a rapid aging rate, with 39% of its residents over the age of 65.城镇的另一个独特特征是约90%的土地被森林占用It is managing to take advantage of this characteristic by promoting forest-based industry and supplying energy using forest biomass toward becoming a recycling society.

与气候变化相关联的风险实事求是,对这些风险的认识在极短时间里急剧提高。

没有适当的管理,森林很容易因自然灾害的发生而受到损害。大雨和地震可点燃致命滑坡When forests are damaged by natural disasters or droughts due to heat waves, it can impact the rate of CO₂捕捉并实现碳返回大气层This prevents infrared radiation from the surface of the earth from escaping to space and contributes to global warming.

Shimokawa has devised and implemented a comprehensive forest management scheme that encompasses planting, afforestation, harvesting, and complete use of wood—its key resource—with no waste.The wood is processed into products such as lumber, byproducts including sawdust, and high value-added products like essential oils, with the remainder becoming wood chips to fuel the biomass boilers.原材料制造设施生产生物量木片

The biomass boilers in Shimokawa supply heat to locations such as public hot springs, nurseries, and elderly care facilities, and the town has achieved a self-sufficiency rate of approximately 70% for heat supply volume for public facilities, and approximately 50% when including use in wood drying at private wood factories.

然而问题仍有待解决。支持木生物质热供应框架的技术在日本尚不存在Despite this, Shimokawa has been a pioneer in introducing wood biomass heat supply facilities, and this has naturally led to numerous problems being revealed.If wood, a finite resource, is going to be used as fuel for forest biomass heat supply, these facilities must be integrated and efficiently operated.

Yokogawa长期参与日本世界领先制造业使其能收集高效节能的宝贵经验And though renewable energy-related technology is still relatively in its nascency, Yokogawa adroitly circumvents this issue thanks to its ability to skillfully integrate its measurement, control, and IoT technologies.

下川市请求Yokogawa帮助开发森林生物量供热系统框架They need to bolster the efficiency of the small-scale, dispersed biomass heat supply operations in Shimokawa, and furnish a stable, sufficient supply of heat.Shimokawa currently operates a total of 11 biomass heat supply boilers, and they plan to take the knowledge accumulated and eventually apply it to similar installations around the country

Ichinohashi Bio-Village, a small district in Shimokawa with a population of about 100, an alarmingly high aging rate, and the need for smart solutions to improve the quality of life, is benefitting from the collaborative undertaking.To manage the distinct elements of the biomass heat supply system established there, Yokogawa employs its e-RT3 edge controller, which collects and processes information from all parts of the system.而这反过来又使得有可能使用快工具实时远程监控系统、易用高可扩缩监控和数据采集系统

全年上川温度在-30摄氏度至+30摄氏度间摇动This reality, along with the fact that there are, in some instances, considerable distances between the supply facilities and those receiving the heat, could result in overcompensation in the form of excessive supply.By forecasting heat demand based on past heat demand data and weather information, and combined with Yokogawa's control technology, more efficient operation becomes possible.

生物量燃料有限性要求保持供求平衡In the near future, Yokogawa's Community Energy Management System (CEMS), which incorporates the e-RT3 and Fast/Tools, will facilitate forecasting of the weather and the anticipated demand for heat at Ichinohashi Bio-Village on a particular day, formulation of an operational plan, and analysis of the results for reflection in future operation.

"Yokogawa provides solutions that improve the stability, efficiency, and safety of operations at industrial plants and other infrastructure facilities by… speeding up processes, reducing workloads, and saving energy."

The ability to apply the resulting data to modeling will facilitate the utilization of an analytical algorithm to optimize the forecasting function to serve as a complement to the feedback control method.这会大大有助于成功管理供求平衡

Yokogawa在2017年8月宣布的2050年三大可持续性目标是实现净零排放并停止气候变化向循环经济过渡并保障所有人的福祉Said Yokogawa President and CEO Takashi Nishijima, "Yokogawa provides solutions that improve the stability, efficiency, and safety of operations at industrial plants and other infrastructure facilities by… speeding up processes, reducing workloads, and saving energy."

Yokogawa will continue to co-innovate with customers in the development of revolutionary new models such as this with the objectives of creating sustainable value and, ultimately, the realization of its longer-term sustainability targets.
