Abstract: In order to help deaf parents take care of babies and reduce deaf parents′ energy and cost of looking after babies, a SCM?based device is designed for monitoring babies′ cry and realizing wireless alarm. Babies′ cries are different as their demands change. The device in this paper can tell babies′ cries based on the template matching method, and send out different alarms so that the deaf parents can understand babies′ needs in time. The practical results show that the device has low cost, is easy to use, and is of great help not only for deaf people, but also for other parents to take care of their babies.
Keywords: baby care; deaf parent; SCM; voice recognition; wireless alarm; intelligent device
0 引 言
在當今社会中,很多家庭的人口结构都趋于两代人,具有听力障碍缺陷的父母或是爷爷奶奶在看护婴儿时往往会显得十分吃力。而在这种情况下,在看护婴儿时,只能让看护人几乎时刻不停地陪在婴儿身边,以防婴儿出现某种情况。这种传统的看护方式不仅耗费看护人大量的时间和精力,在看护人不便时,看护婴儿会显得十分不及时。这样在婴儿有需求时,看护人不能及时出现在婴儿身边,婴儿安全也就存在隐患的可能[1]。
因此,如何提供一种在看护人不便的时候,智能检测婴儿的声音并通知看护人[2],是本文需要解决的技术问题。针对上述所存在问题,提供一种使用简单,成本低廉,婴儿一发出哭声,就能识别婴儿此时的需求并且自动报警的婴儿看护装置。
1 装置总体设计
本文装置由主机和报警手环组成如图1所示[3]。

图中,主机主要由婴儿哭声检测电路和信号发射电路组成,报警手环主要由报警电路组成。报警电路上有红绿蓝三个灯,对应婴儿有三种不同需求时亮[4]。此装置工作时,主机置于婴儿身边,报警手环由看护人佩戴。主机的功能是监测周围声音,一旦检测到有婴儿的哭声并识别需求,立马发射相应的无线信号;报警手环一旦接收到主机发出的信号,立马发出警报来提醒看护人。……
