Usually, with the word "smart", it is generally a product such as a computer phone. Nowadays, the refrigerator has a connection with this word, which makes people feel that happiness is too sudden. Now, every manufacturer is sparing no effort to promote their own smart refrigerator. All kinds of small functions are scattered. Sum up nothing more than these points: can remind the ingredients are expired, can connect to WIFI, can be controlled by mobile phone APP, advanced, there are some cloud service support behind, regularly push some information about diet to mobile APP. But are these what we call a smart refrigerator in the true sense? What exactly is a smart refrigerator, what characteristics should a smart refrigerator have?
Hardware-based requirements:
First, the intelligence of any home appliance is based on one element - the sensor. Most refrigerators currently have only temperature sensors inside. How do you make it smart? Not to mention the need to automatically identify the type of food, freshness, and remaining shelf life. At present, the warranty period reminder of all smart refrigerators is to input the date of purchase, the type of food, and the quantity into the management APP. These can only be regarded as adding more options to the ordinary refrigerator, and can not be regarded as a real smart refrigerator. The future smart refrigerator must be a collection of various sensors, such as odor, RFID recognition, camera scanning, infrared sensing, pressure and line sensing, etc., can automatically sense the various activities of the outside world, and then automatically judge based on the powerful computing power of the configuration behind. The number and freshness of the food.
Second, the degree of intelligence is closely related to the computing power. At present, most of the single-chip microcomputers in the refrigerator still use 8-bit machines. Do you talk to me about intelligence? The 8-bit control unit currently only allows selection and control of two levels of menus. Not to mention the 8-bit refrigerator control unit, the 64-bit iPhone now has a lot of people who don't recognize it as a smartphone (pseudo-background).
Based on software and environment requirements:
To realize the intelligence of the refrigerator, it is impossible to have a mature and interactive operating system. Smartphones only need a very complicated operating system for voice telephony and web browsing functions, and the refrigerator has to implement more functions. Without the control of the operating system, it is definitely not acceptable. Of course, the operating system referred to here is not similar to Windows or Android in the general sense. The main solution is to automatically control various sensors in the refrigerator and realize interconnection control under the Internet of Things.
Follow-up of the external environment is also essential, such as the Internet of Things mentioned earlier. Every ingredient you buy can be networked and can be traced back to the specific location of the origin, the specific time, and the specific operators who serve us. These require external facilities to follow up.
The intelligent era requires highly developed technologies and industry standards. Just add two functions to the refrigerator and call it a smart refrigerator. It’s a bit tricky...·····
High-power electronic power devices are repotted into an integrated module according to a certain combination of functions.
A power semiconductor module is a combination of certain functions and modes, and a power semiconductor module is a high-power electronic power device that is re-potted into a whole according to a certain function combination. Power semiconductor modules can achieve different functions according to the different components in the package. Power semiconductor modules can be used as air-cooled modules with air-cooled heat dissipation, and water-cooled modules with water-cooled heat dissipation.
It is characterized by simple installation, convenient use and maintenance, small size and light weight.
Typical applications in AC/DC motor control, various rectifier power supplies, industrial heating control, dimming, non-contact switches, electric welding machines, motor soft start, reactive power compensation, frequency converters, UPS power supplies, battery charging and discharging, etc.
