Chapter 1257 The Prototype of the Internet of Things

When Li Mu was reborn, Huaxia's Internet industry was at its peak, and the concept of Internet + was booming. This further gave birth to the fact that almost all industries in Huaxia were integrating with the Internet as much as possible, and the express delivery industry was the same.

In Li Mu’s impression, Shunfeng and Jingdong at that time could provide users with real-time logistics information and real-time location. Users can see where their courier is, where it is, who delivered it, and how far the courier is from them. , This kind of perfect customer confidence service relies on the real-time intercommunication between GPS and network.

Li Mu hopes that Taobao Logistics can also have such capabilities in this era. In this case, Taobao Logistics will be at least eight to ten years ahead of logistics companies in the previous life in terms of informatization. Although Li Mu doesn't know much about hardware, he sorted out the details Some key points, I feel that to achieve this in this era, the hardware should have enough foundation, but a brand new product concept is needed to combine these hardware.

That's why he asked Fang Xudong to bring hardware experts over to present to them some of his unprofessional but far-sighted ideas.

Li Mu said to everyone: "I believe that real-time positioning equipment should not be difficult to implement, because the current GPS satellite positioning module and GSM mobile communication module are ready-made, as long as the two are integrated, the device can pass through the GSM communication module. , Real-time transmission of GPS coordinates and location information The real-time positioning information equipped with the container should be correct, right?"

As a communication expert, Hu Bo immediately nodded and said: "The more popular mobile communication technologies are GSM and CDMA, both of which can realize the real-time data transmission function you just mentioned, and although the price of the GPS module is relatively high, but in It’s already commonplace in a lot of areas, so combining the two into one shouldn’t be too difficult.”

Li Mu nodded: "Since these two functions can be realized, let me talk about my other ideas."

After a pause, Li Mu said: "The reason why I need to add radio frequency technology support to these two functions is that I hope that in the future we will install such equipment on every vehicle, every trailer, and every large express package. , and then install radio frequency reading devices for all logistics nodes, so as to improve our operational efficiency."

"For example, we put ten large parcels in the container on the Beijing A555. These ten large parcels must be sent to the Shanghai stock market for sorting and transfer. Then when these ten parcels are loaded, they will be directly passed through The radio frequency technology in the car automatically reads, records and uploads, and then the car is on the road, and we can use the GPS coordinate data sent by GSM to monitor the location of the car 'Jing A555 hanging' in real time;”

"When the location of this car is 20 kilometers or 10 kilometers away from the distribution center in Shanghai, the system will automatically display the information of this car on the big screen next to the staff who pick up the car at the distribution center to remind them of this situation. The car is about to enter the station, and the staff can see its cargo information in real time. It is loaded with ten large packages, and the relevant information is also clear at a glance which of these large packages are going to the business outlets in the surrounding areas of Shanghai. In this way, before the car arrives, our workers can get ready. As soon as the car comes in, the radio frequency reading device outside the door can immediately confirm the identity of the car and the package in the car, and directly remind us The pick-up worker, the car has arrived, ready to work immediately, and then the ten packages can be immediately transported to the loading place that will go to their respective destination business points as soon as the car arrives. In this way, the overall efficiency should be improved a lot of."

Li Mu's hardware idea is basically equivalent to a set of GPS tracker, plus a set of equipment similar to highway ETC, but Li Mu doesn't know whether it is realistic to develop such a device based on the current hardware foundation.

As a communication expert, Hu Bo thought for a while, and then said to Li Mu: "President Li, this set of hardware is achievable, let me disassemble it first and talk about it.

Because your idea of ​​these two sets of equipment includes GPS and GSM, so I will talk about these two pieces first. "

After a pause, Hu Bo continued: "We can directly purchase GPS modules and GSM modules, and then purchase a batch of SIM cards from the operator that can run data, and use their network for support, which will involve a part of the communication protocol. , but it is not a problem, the protocol is open, and the cost is very low, and it can be easily realized by integrating single-chip microcomputer technology. The basic structure is GPS chip, GSM chip and single-chip microcomputer.”

"As for radio frequency technology, I am not an expert in this field, so I am not very sure, but I heard that there is a non-parking toll system in foreign countries. Although it is not popular in our country, there are already a few abroad. The country is using it, and this set of technologies should be consistent with our needs."

"The principle is based on a radio frequency technology called RFID. This technology generally requires two sets of hardware and one system. One set of hardware is placed in the car, and the other is placed in the road toll station. Users drive in or out. There is no need to stop on the expressway. When it passes the toll booth, the equipment at the toll booth will automatically read the information of the equipment in the car, and then record its starting point in the system. When it arrives at the destination and leaves the expressway At that time, you have to go through the toll booth again, and the information will be read again. Once the two data are combined, you can know when and where the car got on the expressway, and you can also know when and where the car is. Get off the highway at the location, then calculate the amount that needs to be paid, and then perform a set of cost calculations. I think the principle of this technology is enough to support the needs you mentioned before. We only need to combine this function with GPS and GSM modules. Integrate and you can achieve all your needs."

Li Mu nodded in agreement, and said with a smile: "This kind of technology is needed as a support. If the technical problems can be solved, then it shouldn't be that difficult to develop such a hardware product, right?"

Hu Bo said: "It mainly depends on what kind of hardware and solutions are used, and then the integration, as well as the need to write microcontroller programs, and at the same time industrial design. Industrial design is easy to say, but it is quite troublesome in practice, such as For mobile phones, we have to repeatedly think of ways to reduce the size of the motherboard, and make mutual adjustments and compromises with the appearance design. After finally encountering a final objection, we will find a foundry for mold production, but if we only use it for ourselves , the industrial design can be done without so much refinement, so that our whole process can be much faster.”

Li Mu said: "This piece of equipment is mainly installed in truck tractors, trailers, containers, and large express packages, so there is no need for too complicated industrial design, as long as it is reliable and practical."

As he said that, Li Mu said again: "However, the courier I just mentioned holds a terminal. This involves our corporate image, so we still need to design it better, with a sense of technology and a sense of high-end."

Hu Bo said: "The handheld device you mentioned, in addition to the GPS and GSM modules just mentioned, also needs a set of scanning equipment, but this is not a problem. Our current system has fully supported the scanning equipment. The code gun can quickly identify the code and upload it to the server. We have solved this problem a long time ago, even if it is replaced with a handheld device, it is not very troublesome, just to change the data transmission from the network cable to the GSM mode wireless transmission.”

Li Mu nodded: "It is true in theory, but we can't just develop a blind code scanning device for our couriers, we have to give him a screen and a system so that they can have more Operating space, for example, if we add a mobile phone screen to this equipment, he can choose whether to scan the code for pickup, scan the code before delivery, or scan the code after delivery; "

"At the same time, we also need to make this device a remote business processing terminal. For example, if a user in our building places an order online and fills in the address here to send a courier, then our server is receiving After arriving at his order demand, we must immediately use the location of the terminal device on our courier to find the nearest courier around, and then send him a pick-up notice, and at the same time pass the order information to him in the form of a text message. "

"Alternatively, we can automatically screen the delivery progress of the courier through the code scanning record of the courier when he leaves. courier, and it has not been properly delivered, we can determine that courier A has delivery business in this building, so he will definitely come to this building, so that we can give him the priority of picking up the task , so that we can minimize our labor waste and make the whole process more efficient.”

Fang Xudong immediately said: "Mr. Li, I will organize a new project team today to tackle the hardware devices you mentioned."

Li Mu nodded: "Communicate with colleagues in the patent department, and don't let go of any patents that can be applied for during the research and development process."

"clear."

Li Mu said: "Think of this matter as the first key research and development project of our hardware laboratory. While you are developing the combination of GSM and GPS modules, on the one hand, you must make the two sets of modules more compatible and adaptable. On the one hand, we need to think more about the effects they can produce when they are combined with other devices. GSM, GPS and single-chip microcomputers, as long as the three are well integrated, we can connect all possible things to the Internet. The future Internet of Things era."

The Internet of Things is still just an abstract concept in this era. Even Western countries have not embarked on real research and development of the Internet of Things. Therefore, when Li Mu talked about the Internet of Things, everyone present was at a loss. Although they I have heard of this concept, but I don't know how to implement this concept in my mind.

Li Mu said: "The set of equipment we installed on the vehicle has actually realized the basic 'Internet of Things', but the future of the Internet of Things should not be just one-way transmission of information, it should have more practical Smart function, let me give you an analogy, if I ask you to develop a new type of bicycle lock, this kind of lock does not have a keyhole, but uses a GSM module and a single-chip microcomputer module to control a set of miniature relays, and then connect Put in a GPS module and use a lithium battery as a power source, so that the bicycle equipped with this bicycle lock is already connected to the Internet.”

Li Mu wants to use the concept of remote unlocking of shared bicycles as a case of the Internet of Things to give a few people a popular science, but there is a very big problem that there are no smart phones, and there is no mobile phone scanning code, so Li Mu modified the logic. , Changed the link of scanning codes with smartphones to sending text messages via GSM with ordinary mobile phones.

Afterwards, Li Mu went on to say: "I give this bicycle a unique ID, and save the matching information on the server, and then throw this bicycle on the street for our specific users to use freely. The specific logic is: if this The ID of the car is 6666, so when the user sees the car, he only needs to send the number 6666 to our server by text message, and the server will pass the GSM module after verifying that his mobile phone number is qualified for unlocking. , send an unlock command to the lock on this bicycle, and then the GSM module will pass the received command to the microcontroller, and then the microcontroller will control the relay, what do you think will happen?"

Fang Xudong said excitedly: "The single-chip microcomputer receives the command to power on the relay and unlock the car in an instant!"
