Abstract:

This paper presents a comprehensive Indoor Intelligent Environmental Monitoring and Control System. It applies the robot, which owns Embedded Human-computer Interaction System, to monitor the ambient temperature, the air humidity and the air flow rate and to judge the indoor comfort level on the basis of the Fuzzy Judgment and then the corresponding proposal is raised. At the same time, the system uses projection technologies in combination with environmental psychology to improve indoor lighting so as to give user a better visual perception. The Indoor Intelligent Environmental Monitoring and Control System integrate as a whole to provide user kinds of fabulous home experiences and entertainments.

SECTION I.Introduction

At present, only high-end office building or a landmark use the professional environmental monitoring technology. Low-cost of such a set of monitoring equipment does not exist for normal users to be equipped. Although the existing intelligent monitoring system is well developed, there exist shortcomings, such as poor flexibility and so on.

According to this instance, this paper proposes the Indoor Intelligent Environmental Monitoring and Control System which based on environmental monitoring to improve room environment in accordance with the state of the surroundings. At the same time, it combines with the environmental psychology [1] and adds the idea of the robot to increase practical applicability and entertainment of such new-tech system.

SECTION II.Technologies

Indoor Intelligent Environmental Monitoring and Control System is a integrate system consists of environmental monitoring and control functions. The system circuit design is divided into three blocks, sensor system, projection system and image processing system. As shown in Figure 1, the sensor system stores and analyses the real time data or pass the data to projection system to display. Projection system can also display the images and videos taken by the image processing system. According to the reality state of environment, the projector applies the visual scheme to Improve the light distribution to meet the requirements.

A smart robot would be introduced. The robot plays a role of moving station which carries the inserted devices to get the aimed information everywhere inside of the room. The moving station could solve the problem of a lack of inflexible that fixed devices generate, such as blind spot for detecting.

Follows are the big three technologies of the system on show.

A. Environmental Monitoring technologies

Environmental Monitoring could be realized by analyzing the characterized variables of environment. Since the sensing devices have the ability of sensing, recording, quantizing and displaying these characterized variables, constructing such a sensing system of integration to do the analysis, would be significant. That is, the system quantizes the obtained data from the sensors and outputs the final analysis, and then the output signals would be delivered to corresponding devices located on the interface to improve and regulate the surroundings of our space we reside in.

The characterized variables we mentioned are as follows: Ambient Temperature, Light Intensity, Air Flow Rate and Air Humidity. The environment is influenced by various of factors, so it should be considerate. The degree of comfortable would be identified in the way of Fuzzy Judgment [2] [3], for the degree of comfortable is obscure and it differs from customer to customer. Multiply Parameters Sensor System measures the variables directly and would display the result. The typical structure chart of the system is indicated in Figure 2.

The measuring methods are listed in the Table I.

B. Projection technologies

Projecting apparatus are commonly used in nowadays. The projection system, especially for the micro-projector, is convenient but costly for users. So the new developed technologies would be applied in the system to display the details on account of its portability, dexterity and easy replaceable insertion. The Indoor Intelligent Environmental Monitoring and Control System calls FLCoS (Ferroelectric Liquid Crystal on Silicon) [4] and LED (Light Emitting Diode) micro-projection system together. As showed in Figure 3, the Three Primary Colors (R short for Red, G short for Green, B short for Blue) are lighted on by the LED optical source and LED drive system. They firstly travel through the Beam Shaping System and would be transferred into uniformity beams, then the Polarizing Beam Splitter divides the uniformity beams into the P and S type. Then, form the polarized light. After the upper steps, the polarized light shines on the FLoCS projection plate. The FLoCS projection plate is a Reflective Spatial Light Modulator, and it generates pixel images based on the siguals affecting upon the voltage and sustained time of polarized, of which signal is exported by the architecture of Video Control System. Finally, the handled lighting beams go through the PBS again and then they are amplified by the Projection Lens to achieve the goal of physical projection.

After verification of documents, the optical efficiency of the lens used in the system is 88.4% and gets approach to the TIR Lens system that are commonly used. Specially, the Projection Lens in the system is sphere shaped and is easy to be manufactured with low cost. PBS optical efficiency is 96%. This feature makes the luminous flux of 16 1m project on the FLCoS display chip. And whole system reaches 10% referring to optical efficiency [5].

室内智能环境监测与控制系统设计指南

摘要：

本文提出了一个全面的室内智能环境监测和控制系统。它采用具有嵌入式人机交互系统的机器人来监测空气环境的温度、湿度和空气流量，并在模糊判断的基础上判断室内的舒适程度，然后提出相应的建议。同时，该系统将投影技术与环境心理学相结合，改善室内照明，为用户提供更好的视觉感受。室内智能环境监控系统整体集成为用户提供各种精彩的家庭体验和娱乐体验。

第一节介绍

目前只有高端写字楼或地标采用专业的环境监测技术。对于普通用户而言，这种监控设备的低成本并不存在。虽然现有的智能监控系统发展较好，但存在灵活性差等缺点。

针对这种情况，本文提出了基于环境监测的室内智能环境监测与控制系统，根据周围环境状况改善室内环境。同时，它结合了环境心理学[1]，并增加了机器人的想法，以提高这种新技术系统的实用性和娱乐性。

第二节。技术

室内智能环境监测和控制系统是一个由环境监测和控制功能组成的综合系统。系统电路设计分为三大块，传感器系统，投影系统和图像处理系统。如图1所示，传感器系统存储和分析实时数据或将数据传送到投影系统进行显示。投影系统还可以显示图像处理系统拍摄的图像和视频。根据环境的实际情况，投影机采用视觉方案来改善配光以满足要求。

将引入智能机器人。机器人扮演移动台的角色，携带插入的设备以获取室内各处的目标信息。移动台可以解决固定设备产生的缺乏灵活性的问题，如盲点检测。

以下是展会上系统的三大技术。

A.环境监测技术

环境监测可以通过分析环境的特征变量来实现。由于传感装置具有传感，记录，量化和显示这些特征变量的能力，所以构建这种集成的传感系统来进行分析将是重要的。也就是说，系统量化从传感器获得的数据并输出最终的分析结果，然后输出信号将被传递到位于界面上的相应设备，以改善和调节我们驻留的空间的环境。

我们提到的特征变量如下：环境温度，光强度，空气流量和空气湿度。环境受各种因素的影响，所以应该考虑周到。舒适程度可以通过模糊评判[2] [3]的方式识别出来，因为舒适程度是模糊的，而且它不同于消费者。乘积参数传感器系统直接测量变量并显示结果。该系统的典型结构图如图2所示。

测量方法列于表I中。

B.投影技术

投影装置现今普遍使用。投影系统，特别是微型投影机，对用户而言是方便但昂贵的。因此，新开发的技术将被应用于系统中，以显示其便携性，灵活性和易于更换插入的细节。室内智能环境监测和控制系统将FLCoS（硅铁电液晶）[4]和LED（发光二极管）微投影系统称为一体。如显示在图3中，LED光源和LED驱动系统点亮三原色（红色为R，绿色为绿色，蓝色为蓝色）。它们首先穿过光束成形系统并被转换成均匀光束，然后偏振光束分光器将均匀光束分成P型和S型。然后，形成偏振光。在上面的台阶之后，偏振光照在FLoCS投影板上。FLoCS投影板是一种反射式空间光调制器，它根据影响电压和极化持续时间的信号产生像素图像，其中信号由视频控制系统的结构输出。最后，被处理的光束再次通过PBS，然后它们被投影透镜放大以实现物理投影的目标。

在验证文件后，系统所用镜头的光学效率为88.4％，并接近常用的TIR镜头系统。特别地，系统中的投影镜头是球形的，并且易于以低成本制造。PBS光效为96％。这一特性使得FLCoS显示芯片上的光通量达16 1m。整个系统参考光学效率达到10％[5]。重要的是，该系统的集成大大减少了投影机的体积，例如，该系统可能在几个月后插入到智能手机中。因此，它使得系统在体积微小方面显着。

C.嵌入式人机交互系统和图像处理系统

为了给用户呈现出令人着迷的视觉效果，我们使用智能机器人拍摄照片，而不是照相机拍照。另外，开发集中于情绪调节的用户体验是我们的热衷方面。

该机器人是一个集成系统，配备微控制器单元ATmegal28 [6]，TMS320F28l2 [7]作为移动控制器，超声波传感器进行周围检测。它还执行动态映射，动态决策，行为控制和处理的功能。

智能机器人通过Image Colleting卡和CMOS感应元件来拍摄图像。互补金属氧化物半导体（CMOS）以更低的成本和能量消耗提供更好的图像形成和更高的帧速率。超声波传感器模块通过测量与屏障的距离来避开。人机交互界面可以安装在我们的终端上，例如我们的电话或电脑。图4显示了一个可用的人机交互界面设计。

它为用户提供了一个图形界面，并通知用户有关信息，例如到屏障或移动轨迹的实时距离。

D.环境心理学

环境和行为的关系是互动的，彼此融合在一起。我们通过改变房间环境作为论文的主要话题，在调整人的情绪方面起到积极的作用。根据监测数据，可以得出房间优势和劣势的结论，如人体感觉舒适的垂直高度。另一方面，它为用户提供室内分发建议，或者帮助他们至少进行调整。

抽象地说，空间结构，背景和颜色对人的感觉和心理刺激更有意义。详细而言，暖色调的高亮度让人感到闭合和活跃，而冷色调的低亮度给人留下的感觉是距离和清醒。明亮和暖色的应用是为了营造友好的氛围。

在房间的空间结构不易改变的情况下，在某种程度上，通过投影技术调整背景和颜色似乎是最佳选择。互动系统通过程序发布基于人类行为和习惯的相关执行命令，智能调整气氛。

第三节。系统性能

该系统有其自身的特点。它反映了用户体验系统时的三项杰出表现。

A.实用性

它的实用性标志着系统可以随时随地自动监控房间状态，而不是像现在主要监控房间或用手工劳动力来确定室内环境。作为非成本或空闲时间的消费，它会产生切合实际的价值。

B.娱乐

娱乐体现在人机交互的过程中。人们可以享受非常舒适的室内环境，也可以亲身体验日常生活中控制机器人的乐趣。可视界面使这个过程更有趣。投影技术的应用带来了品牌视觉体验，延续了丰富多彩的生活。

C.经济

它反映出这种设备的初始投资可以达到理想的低成本和专业的房间监控。整个系统倾向于在更复杂的情况下应用。用户会喜欢拥有这个具有良好经济效益的成本效益系统。

第四节。结论

本文从技术和性能两个方面分析，论证了基于环境监测技术的室内智能环境监测与控制系统的应用可行性。这样，使用户能够实现自己家庭的舒适程度并及时采取适当的措施。我们需要做的是将机器人放入房间，这将自动完成一系列变换。这是一个娱乐，实用和经济的综合室内监控系统。

随着监控技术的灵敏度不断提高，环境检测将更加辉煌。这种智能互动系统的优化将真正发挥作用，我们人类将从中受益良多。
