Winning the witty "cloud" behind the intelligent hardware thousands of miles away

The current smart hardware market is extremely popular, but there are very few products that can really catch the pain points of users. Where is the future breakthrough? There is a point that everyone is raising, that is, the function and service aggregation that is dedicated to building intelligent hardware.

We know that the most successful smart hardware to date is the smartphone, which is an aggregation of services and functions. With the camera function plus the phone function, coupled with powerful computing power and network capabilities, the smartphone has successfully entered the hands of almost everyone. Future smart hardware should also be the direction of this development. Let's take another example related to the Internet of Vehicles. The charging pile of the electric car provides the charging service. After the charging pile is connected to the Internet, it can be connected with social services like WeChat, plus the location location function and payment. Service, you can combine a new user experience. Drivers can quickly find the available charging piles in a strange city, make reservations and pay via WeChat, no longer have to worry about finding a place to charge or a long queue.

However, in order to have such a cohesive force, there is a “brain” that can be managed behind the scenes. Now it seems that it can serve as the core, only the cloud platform. Different from Alibaba Cloud, Amazon Cloud, and Tencent Cloud, which are traditional Internet basic service platforms (they mainly provide cloud computing and data storage services for SMEs), here is the cloud for intelligent Internet services development for emerging IoT. platform. Throughout the entire intelligent hardware market, the platform that can provide cloud service functions can be said to be rare, and the wit cloud is one of the few. With the opportunity of this special issue, the author and the cloud of CTO (CTO) Mr. Liu Wei discussed in depth the details of the intelligent hardware cloud platform.

Why is the cloud platform particularly important for smart hardware? Liu Wei explained this. First of all, we must know that most of the hardware is limited in terms of calculation and storage due to factors such as cost and volume. After the hardware is connected to the cloud, the hardware is invisibly expanded. ability. To put it bluntly, the data that the original hardware can't save can be stored in the cloud. The original hardware can't figure out the results, so the cloud can calculate it.

On the other hand, hardware can be made more flexible or smarter. It turns out that the business logic of some devices needs to be written in the hardware, and now this part and the logic of intelligent decision-making can be put into the cloud. “For example, we have done a smart pet house. There is a function that when the temperature and humidity reach a certain level, the air blower will be turned on to adjust the ambient temperature. What is the specific threshold of this temperature and humidity? Technology, we can give this decision to the cloud. The cloud can be based on what small animals are in the pet house, whether the location of the pet house is south or north, when is the time, and a series of conditions to decide whether to open the wind Device. This makes the business logic originally written in the hardware more diverse and smarter."

How does the wit cloud help to achieve intelligent hardware access to the cloud? We can first look at the basic architecture of the current smart hardware, which is what we often call the golden triangle, that is, the cloud, smart hardware, and smartphone applications. Most of the technology in the cloud is the technology of the Internet. Unlike the fields familiar to hardware engineers, we need tools to help developers access better and faster. For this reason, WitCloud provides a small firmware program called GAgent, which runs on the hardware platform, usually in the Wi-Fi module, or in the hardware master chip. GAgent plays a role of linking up and down. For the cloud, it implements all the wit cloud interfaces, allowing the hardware to connect with the cloud. For the main control chip, it provides a set of packages that are friendly to embedded development. Hardware engineers can program for the business without having to think about the details of cloud communication.

Intelligent hardware special issue

Off-line 12V Battery Smart Pulse Restore System, also be called Battery Maintenance System or Battery Restore Solution: mainly used in the whole industry of Electric Vehicle Battery (EV as electric bike, motor and Car ), Car and Truck Start-up battery, Sightseeing car and Golf Cart power batteryWind and Solar energy storage batteryUPS Back up power systemTelecom base site battery , State Grid and Military battery for sudden affair, etc.

12V Battery Pulse Restore  off-line System fully take into account the inconsistent of the physical resonance frequency between lead sulfate crystal and battery plates, select the optimal frequency of pulse waveform and pulse current intensity to "break" and "decompose" the lead sulfate crystals, ensure the best restoration effect of sulfide battery without any damage to the plates. In order to Reduce Internal Resistance and Increase Battery Capacity and Voltage effectively.

The system is composed of 3 parts and a professional standard restore process: 1) 12V Battery Restorer Device(4.5~300Ah); 2) 12V Battery Digital Pusle Charger; 3) 12V Battery Discharge Tester.  Lead-Acid Battery Restoration system and Solution is applicable to all of Lead Acid Battery(AGM, GEL, VRLA, MF, Flooded, Dry, Traction, Deep cycle and Stationary), and widely used in 12V (4.5~300Ah) cell batteries. 

Product features
1.  The smart pulse with fast rising front is resonant with the crystal of lead sulfate to dissolve the large lead sulfate crystal under the action of charging pulse, which can improve the capacity and prolong the service life of the battery.
2.  No need to add any chemical additives, does not change the internal electrolyte composition of the battery, safe and reliable; For water loss batteries only need to add deionized water before restoring. The output pulse voltage and pulse current are strictly limited.
3.  4 independent output, can repair 4PCS 12V/4.5Ah-300Ah cells at the same time without interference.
4.  Each system is equipped with "capacity selection" gear, according to the different capacity of the battery to select the precise gear, can be ensure better protection of battery plate in repair working.
5.  Each system is provided with automatic repair function, automatic repair system will smartly adjust the pulse duty ratio based on the size and conditions of the battery without anyone on duty.
6.  Each system is equipped with "High resistance repair" function, select the high resistance repair, specially for the long term stored batteries, even if the OCV is 0 Volt, but also can be easily activated.
