摘要
現(xiàn)有火災(zāi)報(bào)警主要采用有線方式，耗費(fèi)材料、故障率高且難于實(shí)現(xiàn)互聯(lián)報(bào)警。采用無線方式能夠很好的解決互聯(lián)報(bào)警、降低成本。利用MSP430F227 +CC250搭載Simplici Ti實(shí)現(xiàn)節(jié)點(diǎn)互聯(lián)，數(shù)據(jù)中心節(jié)點(diǎn)連接至PC機(jī)，PC機(jī)能實(shí)時(shí)監(jiān)控節(jié)點(diǎn)信息，在火災(zāi)到來時(shí)能夠及時(shí)準(zhǔn)確的實(shí)現(xiàn)本地報(bào)警和遠(yuǎn)程報(bào)警。本設(shè)計(jì)的火災(zāi)節(jié)點(diǎn)為超低功耗，休眠時(shí)只有不到1uA電流。它具有較強(qiáng)的工程實(shí)踐意義和應(yīng)用前景。

Abstract
Existing fire alarm system adopts cable way. It expends materials and has a high failure rate,it also hard to implement interconnected alarm. Using wireless means can solve interconnected alarm and reduce costs very well. Using MSP430F227 + CC250 together with Simplici Ti protocol can realize nodes interconnected. Make the access point connecte to the PC , PCS monitors node information in real-time,it can realize local alarm and remote alarm timely and accurately when the fire comes. The fire node in this design uses ultralow-power consumption, Its standby current is less than 1uA. It has strong engineering practical significance and application prospect.
