One kind of scheme in Hotel Guest Room Service and Management System based on CAN bus is presented. The system's structure and main function are expounded. The work principle and design of the system's hardware and software are explained. The realization of the system's hardware and software is detailed from aspects of improving system's anti-jamming and fault self-examined capability, and the block diagram of each part's circuit is given. Finally, features of the system are summarized, and a comparison with the system based on RS485 was made to prove the advantages of the system. By practice, CAN bus in the system can transmit data steadily and reliably.展开更多

Ecotourism is one kind of tourism industry that also consists of complex service providers like travel agents, hotels, transportations （such as airplane, bus, and ship） restaurants, and destinations, connecting with operational diversity; therefore, those of supported services are linked with a supply chain together, and its management is called ecotourism service supply chain management （ESSCM）. Moreover, a low-carbon operation management has also become an important challenge to ecotourism nowadays. Based on the problems of service and low-carbon operation management made together above, exploring an effective solution into ecotourism is worthy. Using ESSCM as a strategy for solving industrial problems of service and low-carbon operations management in ecotourism is explored in this paper. The contributions here include clearly explanations of what ESSCM is and how ESSCM is used with low-carbon operations as a sustainability strategy, and finally a practical case study is also examined in the end.展开更多
为探索能源服务商(energy service provider,ESP)参与下,多个IES间电、热、碳多能点对点交易(peer-to-peer,P2P)与能量管理新模式,提出了一种考虑多主体交互策略的综合能源系统P2P能-碳管理方法。构建了ESP和IES多主体参与下的双层能量...为探索能源服务商(energy service provider,ESP)参与下,多个IES间电、热、碳多能点对点交易(peer-to-peer,P2P)与能量管理新模式,提出了一种考虑多主体交互策略的综合能源系统P2P能-碳管理方法。构建了ESP和IES多主体参与下的双层能量管理框架。建立了双层电-热-碳能量管理模型,上层模型基于强化学习框架,优化ESP和IES合作联盟之间的能量管理策略,下层模型基于纳什谈判博弈理论,优化多个IES之间的合作运行策略。针对典型系统进行算例研究,分析了P2P模式下综合能源系统最优能量管理策略,结果表明:所提能量管理方法能够有效进行电热调度,实现系统的收益最大化,降低系统碳排放量。展开更多
