【摘要】：物聯(lián)網(wǎng)技術(shù)正帶動酒店向智能化方向發(fā)展;相比于普通酒店,主題酒店更加強(qiáng)調(diào)個(gè)性化服務(wù),也對智能化有更高的要求。然而現(xiàn)有酒店控制系統(tǒng)尚存在諸多不足之處:其一,應(yīng)用程序與各種異構(gòu)設(shè)備之間耦合性過緊,可移植性較差;其二,系統(tǒng)難以有效支持異構(gòu)設(shè)備之間的互操作;其三,系統(tǒng)沒有充分整合和利用用戶狀態(tài)和環(huán)境狀態(tài)等信息,難以為用戶提供主動服務(wù)。本文以異構(gòu)設(shè)備的管理、控制和互操作以及客房智能化服務(wù)為研究目標(biāo),構(gòu)建一套面向主題酒店的動態(tài)可擴(kuò)展控制服務(wù)系統(tǒng),以期解決以上三個(gè)問題。該控制服務(wù)系統(tǒng)主要由設(shè)備中間層和上下文感知服務(wù)框架兩部分組成,前者旨在解決異構(gòu)設(shè)備的管理、控制和互操作問題,后者旨在支撐客房智能化服務(wù)。本文主要研究內(nèi)容和工作可概括如下:(1)建立了一種面向狀態(tài)對象、操作對象、參數(shù)對象和服務(wù)的設(shè)備描述方法,并以此為基礎(chǔ)構(gòu)建了設(shè)備中間層。將設(shè)備功能表示為狀態(tài)對象、操作對象和服務(wù),從而屏蔽設(shè)備功能的異構(gòu)性,并較好地支持設(shè)備之間的互操作:一方面,可以通過配置實(shí)現(xiàn)設(shè)備之間靜態(tài)的互操作;另一方面,通過動態(tài)的服務(wù)發(fā)現(xiàn)和調(diào)用可以實(shí)現(xiàn)設(shè)備的動態(tài)協(xié)作。設(shè)備中間層基于虛擬設(shè)備、網(wǎng)絡(luò)適配器機(jī)制解決了異構(gòu)網(wǎng)絡(luò)設(shè)備的接入、管理、控制和互操作問題,使系統(tǒng)具有良好的可移植性和動態(tài)可擴(kuò)展性。(2)設(shè)計(jì)了一個(gè)上下文感知服務(wù)框架。為提高客房服務(wù)的智能化水平,引入上下文感知計(jì)算技術(shù),實(shí)現(xiàn)系統(tǒng)對用戶、空間狀態(tài)等信息的感知、推理,為用戶提供及時(shí)、主動的服務(wù)。建立了以用戶、空間狀態(tài)和服務(wù)為核心的本體模型,基于Jean工具實(shí)現(xiàn)了基于本體和自定義規(guī)則的上下文推理,并設(shè)計(jì)了上下文信息的分發(fā)方法和服務(wù)管理方法。服務(wù)框架屏蔽了上下文采集、推理等細(xì)節(jié),簡化了上下文感知服務(wù)的開發(fā),并提高了上下文感知服務(wù)的可移植性。(3)基于OSGi平臺對控制服務(wù)系統(tǒng)進(jìn)行實(shí)現(xiàn),使系統(tǒng)具有良好的動態(tài)演化能力,并將Java NIO、線程池和異步處理等技術(shù)應(yīng)用到系統(tǒng)中,保證了系統(tǒng)在高并發(fā)情況下的性能。引入復(fù)雜事件處理技術(shù)并基于Esper引擎進(jìn)行實(shí)現(xiàn),增強(qiáng)系統(tǒng)對于復(fù)雜環(huán)境狀態(tài)變化事件的感知能力�；贜ode.js實(shí)現(xiàn)了管理系統(tǒng),并基于WebSocket和TCP長連接技術(shù)實(shí)現(xiàn)了實(shí)時(shí)的消息推送。經(jīng)測試分析,驗(yàn)證了建立的設(shè)備描述方法以及構(gòu)建的設(shè)備中間層對于異構(gòu)設(shè)備互操作的有效支持,上下文感知服務(wù)框架能夠有效支撐上下文感知服務(wù)的開發(fā)。相比于現(xiàn)有系統(tǒng),本系統(tǒng)具有更好的可配置性、動態(tài)可擴(kuò)展性、可移植性和更高的智能化水平,為酒店控制系統(tǒng)提供一種新的實(shí)踐方法,具有較好的實(shí)際應(yīng)用價(jià)值。
[Abstract]:Internet of things technology is driving hotels to the direction of intelligence; compared with ordinary hotels, Hotel Theme has more emphasis on personalized services, but also has a higher demand for intelligence. However, the existing hotel control system still has many shortcomings: first, the coupling between applications and various heterogeneous devices is too tight, the portability is poor; second, the system is difficult to effectively support the interoperability between heterogeneous devices; third, The system does not fully integrate and utilize information such as user state and environment state, so it is difficult to provide active service for users. Aiming at the management, control and interoperation of heterogeneous equipment and intelligent room service, a dynamic scalable control service system for Hotel Theme is constructed in this paper, in order to solve the above three problems. The control service system is mainly composed of two parts: the middle layer of device and the framework of context-aware service. The former aims to solve the problems of management, control and interoperability of heterogeneous devices, and the latter is to support intelligent room service. The main contents and work of this paper can be summarized as follows: (1) A device description method for state object, operation object, parameter object and service is established, and the middle layer of the device is constructed based on this method. The device function is represented as a state object, an operation object and a service, thereby shielding the heterogeneity of the device function and better supporting the interoperability between devices: on the one hand, static interoperability between devices can be achieved through configuration; on the other hand, Dynamic collaboration of devices can be realized through dynamic service discovery and invocation. The middle layer of the device is based on the virtual device. The network adapter mechanism solves the problems of accessing, managing, controlling and interoperating the heterogeneous network devices. The system has good portability and dynamic extensibility. (2) A context-aware service framework is designed. In order to improve the intelligent level of room service, the context-aware computing technology is introduced to realize the system's perception and reasoning of user, spatial state and other information, so as to provide users with timely and active services. An ontology model with user, spatial state and service as the core is established. Context reasoning based on ontology and custom rules is realized based on Jean tools, and the distribution method and service management method of context information are designed. The service framework shields the details of context collection and reasoning, simplifies the development of context-aware services, and improves the portability of context-aware services. (3) the control service system is implemented based on OSGi platform. The Java NIO, thread pool and asynchronous processing are applied to the system to ensure the performance of the system under high concurrency. The technology of complex event processing is introduced and implemented based on Esper engine to enhance the system's ability to perceive the changing events in complex environment. The management system is implemented based on Node.js, and the real-time message push is realized based on WebSocket and TCP long connection technology. Through test and analysis, the method of device description and the support of the device middle layer for heterogeneous device interoperability are verified. The context-aware service framework can effectively support the development of context-aware services. Compared with the existing system, this system has better configurable, dynamic expansibility, portability and higher intelligent level, which provides a new practical method for hotel control system, and has better practical application value.
