Chapter 1258 (1/2)

Apart from the sharing bike with little technical content and only four mechanical password locks, other sharing bikes, such as Moby, basically all adopt intelligent locks with networking function and positioning function.

Although this kind of smart lock was born on shared bicycles around 2016, its product logic is very simple, basically the same as Li Mugang's logic. First, there is a GPS module for real-time positioning, so users can see the location of shared bicycles nearby, and the company can also monitor the actual location and driving route of each bicycle;

then It is a GSM module, which is the core Department of single vehicle access to the Internet. GSM transmits data through the network of mobile operators, transmitting user unlock request, server unlock command, GPS signal and user lock signal;

the single chip microcomputer and relay cooperate with each other, in the locked state, the single chip microcomputer control relay can open the vehicle lock in an instant;

finally, each vehicle has a total of There is a fixed two-dimensional code on the bicycle, in fact, it is just an ID. in the era of smart phones, code scanning and unlocking is the simplest, but if it is put in the present, it can be replaced by sending messages, so there is no need for smart phones to participate.

Lithium battery with normal capacity should have very low power consumption to deal with such simple equipment. However, even if the power consumption is low, there will be a time when the power consumption is exhausted. Therefore, when zooming into the whole vehicle manufacturing, an additional set of micro power generation system is needed. When users are riding or braking, they will drive the micro generator to charge the lithium battery. In this way, they can basically ensure that The smart lock of shared bicycle doesn't need manual charging, and can stand by indefinitely.

Fang Xudong is very keen on technical issues. Although he has never seen bike sharing, he understands the whole set of logic that Li Mu said. For him, Li Mu's idea of flying in the sky is so admirable.

After everyone recovered from the shock and excitement, Li Mu said: ”in the example I just mentioned, a relay controlled by a single-chip microcomputer was added, so that when the relay received the command, it would immediately work to unlock the car. That is to say, this system has the ability to actually operate through the Internet, which is what I said Deeper Internet of things can not only connect the goods to the Internet, but also control the goods to a certain extent through the Internet. ”

Speaking of this, Li Mu added: ”think about it, if we produce 10000 bicycles like this and leave them on the streets of Yanjing so that our users can ride them at will, what do you think of this mode?”

Everyone's expression changed from the surprise just now to looking at each other. They didn't understand why Li Mu wanted to get 10000 bicycles on the street. What's the meaning of this? Moreover, the cost of this ”Internet of things” bicycle is not low. Just a set of GPS + GSM + single-chip microcomputer and control module of relay and lithium battery will cost a lot of money. At present, the cost must be in four figures.

Li Mu was puzzled when he saw a few people. He wanted to explain to them how to play bike sharing, but he gave up. The mode of bike sharing is too advanced, and the operation mode of playing capital games by user's deposit also has great risks. Now, because the development of mobile devices is still very limited, it's not the time to get on the horse and share bike with him It's hard for them to understand that the explanation is too penetrating, which may lead to unexpected abnormal products in advance. So Li Mu waved and said, ”I'm just making a simple analogy. If we are familiar with this set of hardware, there will be a lot of room for future use.”

After that, Li Mu said: ”let me make another analogy. If we make GSM module, MCU module and relay module mature, we can apply it to many fields in our life. For example, we can use it to create a socket that can control the switch by remote control. Users only need to send a command to the GSM module in their mobile phones, and then they can control it The relay is used to turn on the power and the socket is used for power transmission. Similarly, the user only needs one command to turn off the relay and stop the power transmission of the socket. In this way, the switch of the home appliance can be controlled remotely. Connect the socket to the water heater, and Send a message to the water heater to boil water before going home. Connect it to the rice cooker and put rice and water on the way Put it away, send a message to let it start before you go home, there will be a pot of delicious rice waiting for you when you go home, connect it to the light, and then it can be turned on or off automatically... ”

”What I just said is just the most basic function based on GSM data and SMS. If we connect this device to the PC, you can think about how many changes will happen. We can add a variety of intuitive and visual operation interfaces to the PC, such as smart home, all the home appliance switches are connected to the network and edited on the PC side;” br >

”if We will add an infrared transmitter with learning function to our hardware, so that all home appliances can be controlled by computer, air conditioning can be turned on remotely through the network, temperature can be set, TV can be turned on, curtains, lights, sound can be remotely controlled, etc.;

”if we add another temperature and humidity sensor, users can be at any time Know the temperature and humidity of your home. If we add another smoke and gas alarm, once there is smoke or gas leakage in your home, you can immediately send an alarm message to the user... ””If we use it in automobiles in the future, as long as we combine it with automobile circuits, we can use a short message to let the automobile start the engine in advance and turn on the air conditioner, and even through the connection of various sensors of the automobile, let the system automobile send all the States to the user's mobile phone, including the automobile oil quantity, glass water quantity, battery voltage, mileage information, etc Wait... ”

Li Mu's godlike thinking mode stunned all the people present.

No one expected that Li Mu's thinking could be advanced to such a level, and even completely override the whole Internet field, becoming the real God in the Internet industry.
