【摘要】：本文研究的问题是如何利用iBeacon技术的定位优势,配合其他一些智能设备来实现居家自动化系统。通过iBeacon这个定位设备,利用基于位置指纹的定位算法来定位智能手机的位置,而手机的位置即代表了人的位置,在其进入或离开特定区域时触发事先预定义的事件。而事件又分为两类,其一是通过服务端通过智能手机的推送功能,将信息推送到用户的手机;其二是服务端通过网络,调用智能插座的命令,直接控制电器设备,而达到自动化的目的。由于居家自动化系统的使用对象一般为普通消费者,所以在系统开发之初就定下了易操作,低门槛的前提要求。在实践过程中,通过理解和学习基于指纹的定位算法,结合居家定位的使用场景,总结了一个操作流程简单同时又满足定位要求的方法:通过设定事件时在需要触发事件的位置采集指纹信息,来代替离线阶段采集全部指纹信息这一传统做法。通过在线阶段同实时获得的指纹信息进行比较,如果两者一致,则代表事件可以触发。本文实现的居家自动化系统实现了研究之初所设想的功能,通过自定义事件的方式,可以实现丰富多样的自动化需求。同时保留了一定的可扩展性,为未来加入更多类型的事件的实现提供了可能性。不过系统也有不足之处,定位的精度和稳定性方面还不是非常理想,需要在算法上进行优化。以人为中心,探知人的意图从而自动化运行会是未来机器的发展方向。本论文简化了探知人的意图的维度,仅从位置角度进行判定。在自动化运行方面也仅仅通过智能插座来简单控制电器设备。但是相信未来随着更丰富的传感器的加入,以及终端电器标准化的到来,理想的居家自动化不会离人们太远。
[Abstract]:The problem studied in this paper is how to make use of the positioning advantages of iBeacon technology and cooperate with other intelligent devices to realize the home automation system. Through iBeacon, a location algorithm based on location fingerprint is used to locate the location of smart phone, and the location of mobile phone represents the location of human being, which triggers predefined events when it enters or leaves a specific area. The events are divided into two categories, one is to push the information to the user's mobile phone through the server through the smartphone push function, the other is to control the electrical equipment directly through the network and call the command of the smart socket, so as to achieve the purpose of automation. Because the object of home automation system is generally ordinary consumers, the premise of easy operation and low threshold is set at the beginning of system development. In the process of practice, by understanding and learning the fingerprint-based location algorithm and combining with the use scene of home location, this paper summarizes a method that the operation flow is simple and meets the requirements of location at the same time: by collecting fingerprint information at the location where the event needs to be triggered when setting the event, instead of collecting all the fingerprint information in the off-line stage, this paper summarizes the traditional method of collecting all fingerprint information at the off-line stage. The online phase is compared with the real-time fingerprint information, and if the two are consistent, the event can be triggered. The home automation system realized in this paper realizes the functions envisioned at the beginning of the research, and the rich and diverse automation requirements can be realized by means of custom events. At the same time, it retains a certain degree of extensibility, which provides the possibility for the implementation of more types of events in the future. However, the system also has shortcomings, the accuracy and stability of positioning is not very ideal, need to be optimized in the algorithm. People-centered, exploring human intentions and automating operation will be the development direction of machines in the future. This paper simplifies the dimension of exploring human intention and determines it only from the point of view of position. In the automation operation, only through the intelligent socket to simply control the electrical equipment. However, it is believed that in the future, with the addition of richer sensors and the arrival of terminal electrical standardization, the ideal home automation will not be too far away from people.
