【摘要】：隨著我國人口老年化的加劇以及計(jì)劃生育政策的實(shí)行,使得我國出現(xiàn)了大量空巢家庭,且老年人在空巢家庭中占較大比重。在無人看護(hù)的情況下,空巢家庭中的老人由于年老體弱多病、健忘等,常常無法及時(shí)的反應(yīng)和應(yīng)對一些威脅生命安全的隱患,如日常生活中的跌倒、久病纏身臥床不起、廚房失火和煤氣泄漏等情況,會對空巢老人健康安全造成相應(yīng)的傷害,特別是當(dāng)傷害發(fā)生后未能及時(shí)發(fā)現(xiàn)和救助,往往會釀成更嚴(yán)重的后果。除了家中有人看護(hù)外,當(dāng)發(fā)生像跌倒、長期臥床等狀況后,能夠及時(shí)發(fā)現(xiàn)并給予幫助便可以避免更嚴(yán)重的后果發(fā)生。因此本文設(shè)計(jì)的目的是以物聯(lián)網(wǎng)相關(guān)技術(shù)為基礎(chǔ),研究設(shè)計(jì)一個(gè)居家智能守望系統(tǒng),實(shí)現(xiàn)對老年人的守望功能,從而緩解家庭子女和社會的負(fù)擔(dān)。對于本社區(qū)居家智能守望系統(tǒng)的設(shè)計(jì)實(shí)現(xiàn)過程,本文首先在我國人口老齡化和家庭空巢化的分析背景下,以及老人在家易發(fā)生危險(xiǎn)后無人及時(shí)發(fā)現(xiàn),得出了社區(qū)居家智能守望系統(tǒng)的設(shè)計(jì)意義。并分析研究了有關(guān)老年人智能監(jiān)護(hù)方面的國內(nèi)外現(xiàn)狀。其次介紹了智能守望系統(tǒng)的整體設(shè)計(jì)架構(gòu),采用分類架構(gòu),主要分為三部分:檢測部分、集中控制部分和監(jiān)管部分,并對三部分所要完成的功能進(jìn)行了說明。以物聯(lián)網(wǎng)相關(guān)技術(shù)中的傳感器技術(shù)、Zigbee無線傳感器網(wǎng)路技術(shù)、GSM網(wǎng)路技術(shù)、微控制器技術(shù)等為基礎(chǔ)來實(shí)現(xiàn)系統(tǒng)中硬件電路的設(shè)計(jì),共設(shè)計(jì)完成了無線跌倒檢測模塊、無線液化氣體檢測模塊、無線火災(zāi)檢測模塊、熱釋電無線探測模塊和集中控制模塊。并對檢測部分中的跌倒檢測模塊所用到的跌倒檢測算法進(jìn)行了設(shè)計(jì),本文通過分析老人的日常行為活動和跌倒動作,結(jié)合得到的數(shù)據(jù)曲線的分析提出了新的跌倒檢測算法,得到了實(shí)驗(yàn)結(jié)果的驗(yàn)證。最后通過系統(tǒng)的軟件設(shè)計(jì),組建了 Zigbee網(wǎng)路,并對該網(wǎng)絡(luò)進(jìn)行編號后將各個(gè)模塊加入到此網(wǎng)絡(luò)中,各模塊在檢測到可疑數(shù)據(jù)信息時(shí)發(fā)出報(bào)警鈴聲并將信息無線傳輸出去,完成設(shè)備與設(shè)備間、設(shè)備與人間的信息傳輸。在系統(tǒng)的軟硬件整體設(shè)計(jì)完成后,模擬了跌倒、規(guī)定時(shí)間內(nèi)未活動、溫度過高等狀況,模塊檢測出了異常狀況并進(jìn)行了警報(bào),在無解除后將信息通過內(nèi)部網(wǎng)絡(luò)傳輸?shù)搅思锌刂颇K上并在液晶屏上顯示,并通過GSM短信息向監(jiān)管人發(fā)送求助信息。測試了系統(tǒng)的實(shí)用性,并給出了系統(tǒng)的后續(xù)擴(kuò)展概述。
[Abstract]:With the aggravation of population aging and the implementation of family planning policy in China, a large number of empty nest families have emerged, and the elderly account for a large proportion of empty nest families. Under the condition of unattended care, the old people in empty nest families are often unable to respond to and deal with some hidden dangers that threaten their lives, such as falling down in daily life, bedridden with long illness, because of their old age, weak body, and amnesia, etc. The kitchen fire and gas leakage will cause corresponding harm to the health and safety of the empty nest old people, especially when the injury does not find and rescue in time, which will often lead to more serious consequences. In addition to being cared for at home, more serious consequences can be avoided when conditions such as falls and prolonged bed-rest can be detected and helped in time. Therefore, the purpose of this paper is to study and design a home intelligent watchkeeping system based on Internet of things (IOT) technology, which can realize the function of keeping watch on the elderly, so as to ease the burden of family children and society. For the design and realization process of the intelligent watch system in this community, this paper first analyzes the background of aging population and empty nesting of the family in our country, and the old people are vulnerable to danger at home and no one finds them in time. The design significance of community home intelligent watch system is obtained. The present situation of intelligence monitoring for the elderly is analyzed and studied. Secondly, the whole design framework of intelligent watch system is introduced, which is divided into three parts: detection part, centralized control part and supervision part, and the functions of the three parts are explained. The hardware circuit of the system is designed based on the sensor technology of the Internet of things, such as Zigbee wireless sensor network technology, GSM network technology, microcontroller technology and so on, and the wireless fall detection module is designed and completed. Wireless liquefied gas detection module, wireless fire detection module, pyroelectric wireless detection module and centralized control module. The fall detection algorithm used in the fall detection module is designed. A new fall detection algorithm is proposed by analyzing the daily behavior and the fall action of the elderly and combining the analysis of the obtained data curve. The experimental results are verified. Finally, through the software design of the system, the Zigbee network is set up, and each module is added to the network after numbering the network. Each module sends out an alarm ring when detecting the suspicious data information and transmits the information wirelessly. Complete the information transmission between equipment and equipment, between equipment and human. After the overall design of the software and hardware of the system is completed, the fall is simulated, the specified time is inactive, the temperature is too high, and the module detects the abnormal condition and carries on the alarm. The information is transmitted through the internal network to the centralized control module and displayed on the LCD screen, and the help message is sent to the supervisor through GSM short message. The practicability of the system is tested, and an overview of the subsequent expansion of the system is given.
