System software design
The software design of the teaching and playback system includes the software design of the measurement and control computer and the software design of the Arduino mega260 controller of each device.
The control and control computer is the control core of the whole system. The software is written in C#. In the teaching and playback system, the operation data is recorded so that the operating process is replayed accurately according to the recorded data. The data required to be recorded include the operating password, operation action, password from the equipment operator. And action time, the operation of each operation. In order to simplify the recording data, each event code is compiled in advance, and the recording process only records the code, thus greatly improving the efficiency of the recordable sound module.
In the process of training, the computer controls and polls the lower computer every 50 ms, and records the feedback data. In the data record, 50 ms is a unit. The timer is used to control the time. In the process of replaying, first compare the current time and the recorded time, when the recorded time coincides with the current time, the measurement and control computer controls the lower computer to perform the event and completes the event playback.
The Arduino mega2560 controller is responsible for receiving the control instructions of the computer and executing instructions, reading the results of speech recognition, collecting and processing sound data, and controlling speech synthesis by the speech synthesis unit. Arduinomega2560 controller uses serial port interrupt mode to receive commands. Only if the command is correctly received will execute and return the result. If the test and control computer does not receive the return result in a limited time, it indicates that the error occurs, and the measurement and control computer needs to be sent again

I admire the wisdom of modern pre-mothers very much. First of all, whether the length of the prenatal education time they insist on, or whether the use of the method is correct or not. First of all from the consciousness, especially we need to applaud for these mothers. The prenatal education let us understand life, and can experience the surprise of life. However, whether prenatal teaching method is suitable for prenatal teaching, let¡¯s discuss it from 4 angles.
Scientific fetal education must conform to the development process of the fetus.
The reason why the fetal education should emphasize science is based on the ability of baby to have the ability in the womb, and the basic requirement of scientific fetal education is to do the correct prenatal education at the corresponding time of fetal development.
For 10 weeks, HE or SHE’s skin has pressure and tactile function; for 12 weeks, HE or SHE’s brain cells develop at 250 thousand speed per minute; for 14 weeks, HE or SHE will play with the umbilical cord, mother does not feel; for 18 weeks, HE or SHE can hear the mother’s call, singing, storytelling voice; and for 20 week, HE or SHE will suck fingers to prepare for later milk sucking, and hug Memory ability; for 30 weeks, HE or SHE begin to think, also is an expression actor who can express anger and sadness; for 35 week, HE or SHE can feel cold and heat and pain, and it needs to play anesthesia when do the intrauterine surgery…
These abilities are based on the gradual formation and maturation of fetal brain intelligence. And based on these different abilities, we will teach the baby in the early stages of development, through light music, piano music, joyful children’s songs, and classical poetry, and English to promote the development of the brain, as well as the baby began to gradually understand the world. Can tell the story, can be parent-child dialogue, can listen to music, according to scientific planning, let the baby start from 4 months to 10 months complete acceptance of the prenatal education, let the baby is born, more talented than the other children.
