Description
Technical Field
The invention relates to a baby cradle, in particular to a novel multifunctional baby cradle based on an intelligent identification system.
Background
With the progress of science and technology, smart homes gradually enter our lives, aspects of our lives are influenced, and the application of various smart homes not only enriches our lives, but also greatly liberates the hands of people, so that people get rid of boring mechanical labor, and a large amount of labor force is saved. However, even today, the research on the intelligent crib is still deficient, and most of the strollers and cribs are still only used as a carrier to provide a sleeping environment for the baby, and cannot serve families well.
Cribs with a slightly higher degree of intelligence are basically imported products, and are expensive and generally low in degree of intelligence. Through market research and reference of literature data, the prior art is that the crib plays music automatically, and the crib is automatic to sway under artificial control, automated inspection crib inside temperature humidity to the inside real time monitoring of crib at present. Although the prior art has certain intelligent elements, the prior art still has great improvement space, and therefore, the invention of the crib with relatively low cost and high intelligence degree is an urgent problem to be solved.
For newborn babies, their brains are fragile, the head fat does not provide adequate protection to the brain, and the newborn babies have their heads in an unstable state as if the yolk inside the eggs were. For some electric infant cradle, if the shaking frequency is too fast, the mild can affect the brain development and health of the infant, and the serious can also cause the infant to be dementia, even die, and is very dangerous.
The swing modes of the existing baby cradle on the market are almost compound pendulum type, and according to the calculation formula of simple pendulum:
the length of the common crib is about 0.5m, and the gravity acceleration is 9.8m/s2The obtained period is 1.42s, the period of the compound pendulum is slightly larger than the period of the simple pendulum, and the period is 1.5 s. The frequency of such periodic oscillations is too fast for the newborn infant to be healthy, and too fast a frequency not only does not contribute to hypnosis, but may also cause irreversible side effects on the infant.
