Baby accompanying lamp based on crying detection

Abstract

The invention discloses a baby accompanying lamp based on crying detection. An existing sound control lamp is not suitable for infants with insufficient language ability to use. The baby accompanying lamp comprises a main control module, a microphone pickup module, an LED lamp group module and a power supply module. The microphone pickup module comprises a microphone main body and a coupling circuit and is used for collecting external environment sound; the LED lamp group module comprises a plurality of LED lamps and a driving circuit; the power module supplies power to the whole system; and the main control module adopts a chip with a signal processing unit, an arithmetic unit, a storage unit, a signal output unit and a timing unit. The signal processing unit converts sound analog signals into digital signals, the arithmetic unit extracts comparison data and compares the comparison data with stored baby cry characteristic data, if a similarity threshold value is reached, a lamp turning-on signal is output, timing is started at the same time, and after the set time is reached, the LED lamp is turned off. By detecting crying sound of an infant, light is turned on and turned off, and the device is suitable for sleeping of the infant.

Description

technical field [0001] The invention belongs to the technical field of voice detection, and relates to a baby accompanying lamp based on crying detection. Background technique [0002] Taking care of babies is hard work, especially at night, babies often cry loudly due to slight changes in the environment, and parents need to turn on the lights to take care of them, which consumes a lot of energy of parents, leads to lack of sleep, and affects normal work and life. The accompanying light is mainly used when taking care of babies at night, and has the characteristics of small size, portability, and soft lighting. At present, there are many kinds of companion lights on the market, but most of them are manually controlled; there are some smart companion lights that can be voice-activated. However, the existing voice-activated lights are relatively simple to control, and the lights will be turned on no matter what the sound is. There are also some voice-activated lights that ...

Problems solved by technology

However, infants and young children have insufficient language skills and cannot control the lights independently when there is a need for lights

To sum up, the existing baby accompanying lights are far from meeting the needs
