基于ZigBee技術(shù)的無線智能家用燃?xì)鈭?bào)警系統(tǒng)

資 源 簡 介

在研究傳統(tǒng)家用燃?xì)鈭?bào)警器的基礎(chǔ)上,以ZigBee協(xié)議為平臺(tái),構(gòu)建mesh網(wǎng)狀網(wǎng)絡(luò)實(shí)現(xiàn)網(wǎng)絡(luò)化的智能語音報(bào)警系統(tǒng)。由于傳感器本身的溫度和實(shí)際環(huán)境溫度的影響,傳感器標(biāo)定后采用軟件補(bǔ)償方法。為了減少系統(tǒng)費(fèi)用,前端節(jié)點(diǎn)采用半功能節(jié)點(diǎn)設(shè)備,路由器和協(xié)調(diào)器采用全功能節(jié)點(diǎn)設(shè)備,構(gòu)建mesh網(wǎng)絡(luò)所形成的家庭內(nèi)部報(bào)警系統(tǒng),通過通用的電話接口連接到外部的公用電話網(wǎng)絡(luò),啟動(dòng)語音模塊進(jìn)行報(bào)警。實(shí)驗(yàn)結(jié)果表明,在2.4 GHz頻率下傳輸,有墻等障礙物的情況下,節(jié)點(diǎn)的傳輸距離大約為35 m,能夠滿足家庭需要,且系統(tǒng)工作穩(wěn)定,但在功耗方面仍需進(jìn)一步改善。

Abstract:
 On the basis of studying traditional household gas alarm system, this paper proposed the platform for the ZigBee protocol,and constructed mesh network to achieve network-based intelligent voice alarm system. Because of the sensor temperature and the actual environment temperature, this system design used software compensation after calibrating sensor. In order to reduce system cost, semi-functional node devices were used as front-end node, however, full-function devices were used as routers and coordinator,constructed alarm system within the family by building mesh network,connected to the external public telephone network through the common telephone interface, started the voice alarm module. The results indicate that nodes transmit about 35m in the distance in case of walls and other obstacles by 2.4GHz frequency transmission, this is able to meet family needs and work steadily, but still needs further improvement in power consumption.
