After Lin Tian came to the Shuguang production base, he went directly to the No. 2 laboratory!

After seeing the person in charge of the No. 2 laboratory, Lin Tian called him aside, and then said: "The installation steps of the smart housekeeper are still relatively complicated, if it is installed in a family, it may be necessary to dig a trench with a depth of about two centimeters in the wall and floor......

"Yes, chairman, this trench is mainly used to place the induction line, after all, the intelligent housekeeper wants to monitor the security facilities of the whole family, and the main dangerous places are to place a sensor, and then connect the induction line and transmit the information to the control computer in order to carry out comprehensive processing. The head of Lab 2 replied.

"I know that. Lin Tian nodded, and said: "I mean, can you simplify it, such as subtracting this induction circuit and replacing this circuit with other means, such as a certain signal, or what electromagnetic waves, or network ......?"

The reason why Lin Tian asked this is because now the electrical appliance enterprises under the Chen Group are developing intelligent electrical appliances that can be used with the "smart housekeeper".

After all, according to the installation method of "smart housekeeper", it must be started at home, Lin Tian felt that it didn't matter when he installed it, but other consumers would definitely not think so.

"Lin Dong, what you said is not impossible, but if you use wireless signals to transmit information, it may not be 100% accurate, because the signal is easy to be interfered with by the outside world during the propagation process, which will lead to the uncertainty of acceptance. The person in charge of Laboratory No. 2 said.

"First of all, our "Smart Housekeeper" is a security system installed in the home, as long as it is for the home indoors, and the outdoor area is limited. The space of the family is more crowded and the space is not open enough, and the wall in the room is the main obstacle. ”

"Because the wireless signal is in the wireless microwave band. The biggest feature of microwave is that it propagates in a nearly straight line and has a very weak diffraction ability, so the wireless receiving device behind the obstacle will receive a very weak signal, or no signal. Therefore, it is also possible to change the signals sent and received by the intelligent housekeeper to infinite signals, but it needs to be studied in more detail. ”

When Lin Tian heard this, he also understood a little in his heart, if he used wireless signal transmission, it was not impossible, but it was easy to be interfered with by the outside world......

"Then there are electromagnetic waves, which are a type of energy, and any object above absolute zero will emit electromagnetic waves. And the higher the temperature, the shorter the wavelength of the electromagnetic wave emitted. It can transmit information, and our mobile phones use electromagnetic waves to transmit signals. The person in charge of Laboratory No. 2 said.

"Then do you think it's better to use that transmission method!" Lin Tian asked him.

"Electromagnetic wave transmission is used. The person in charge of the No. 2 laboratory said affirmatively, "Lin Dong, there are many places in our society that use electromagnetic waves, so electromagnetic waves are widely used in our lives, and we have certain experience in manufacturing and use. ”

After hearing the words of the person in charge of the No. 2 laboratory, Lin Tian also thought about it and felt that he felt that he was right, the use of electromagnetic waves in today's society is indeed quite extensive, and it is even inseparable from electromagnetic waves.

"But it seems that electromagnetic waves will have a certain impact on the human body!" Lin Tian expressed his doubts.

"Lin Dong, the use of electromagnetic waves will have a certain impact on the human body to a greater or lesser extent, but as long as the transmission frequency is controlled at a safe level, and the band transmitted to the outside world is strictly controlled to a relatively safe level, this impact is negligible. The head of Laboratory 2 explained.

As long as it is not at absolute zero, it will radiate electromagnetic waves to the outside world, and absolute zero is impossible to achieve in nature, so electromagnetic waves are ubiquitous.

In the ordinary environment, electromagnetic waves will not cause harm to human health, but long-term exposure to high-level electromagnetic waves will cause damage to human health.

In fact, not all electromagnetic radiation has an impact on the human body, as long as the intensity is not large, there is not much harm to the human body. At least the various appliances used in the home still have a certain amount of electromagnetic waves, although these effects are negligible......

But the "smart housekeeper" is different, as an important system for supervising the family, it must be all over every corner of the family, if once the transmission of electromagnetic waves is used, it must produce a large number of electromagnetic waves......

"Then can you do it, control the electromagnetic waves that are all over the family within an absolutely safe range......" Lin Tian asked expressionlessly.

"This ...... This ......"

"......?......" Lin Tian was stunned.

"Chairman, if the frequency and band of the emission are controlled within the safe range of the intelligent housekeeper and do not cause harm to the human body, our No. 2 laboratory is willing to try it!" After a while, the person in charge of the No. 2 experiment said.

Lin Tian was immediately happy after hearing this, and said: "Very good, I believe in you, come on, if you succeed, I will not treat you badly when the smart housekeeper is listed." ”

"Thank you, Chairman!"

After hearing Lin Tian's words, the person in charge of the No. 2 laboratory was also overjoyed, so he hurriedly thanked him.

"By the way, I want to tell you that our Shuguang Group has reached a cooperation with Chen's Group on smart housekeeping...... The specifics are..... We mainly provide...... They mainly develop ......"

"Lin Dong, what do you mean is that you want to make all the current electrical appliances intelligent and hand them over to the intelligent housekeeper to control them......" After listening to Lin Tian's words, the person in charge of the No. 2 laboratory gradually understood.

"Yes, I have this in mind. Lin Tian nodded and did not deny that this idea was inspired by the cooperation of his daughter-in-law.

"Okay, Lin Dong, we will make relevant debugging according to the situation!" said the person in charge of Laboratory No. 2.

"Okay, I'm coming to you today, in addition to this matter, I want you to prepare a set of samples of "smart housekeeper" for me, I can be useful. Lin Tian said.

"No problem, there's still one in the lab that's vacant and you can take it and use it. ”

"Hmm. ”

When Lin Tian put the vacant "smart housekeeper" into the car and was about to leave, the person in charge of the No. 2 laboratory suddenly asked, "Lin Dong, may I ask when the machinery and equipment I asked you to purchase last time will arrive?"

"Soon, it's in transit now, and it will arrive soon!"

After Lin Tian finished speaking, he started the car, and with the rotation of the engine, the black shadow gradually disappeared at the end of the road......
