Electronic enthusiasts eight o'clock: Artificial intelligence (AI) has become a hot word in the global technology industry, and various companies have launched the business development strategy of the theme. Although the departure is backward, Apple has already invested and laid out artificial intelligence. According to the latest news from Bloomberg, Apple is developing a special chip for artificial intelligence, which may be used in various devices of Apple to undertake artificial intelligence-related calculations. According to reports, Apple's dedicated chip may be named "Apple Neuro Engine", which will be embedded in Apple's various electronic devices, including smartphones. The chip will share the complex computing tasks of artificial intelligence, including user face recognition, speech recognition, and augmented reality. Bloomberg reported that if independent artificial intelligence chips are used, the overall performance of Apple devices will be improved, including battery life. This fall, Apple will release three new phones, including a 10-year version of the phone with more upgrades (commemorating the 10th anniversary of the iPhone), which will provide wireless charging, OLED screens, and screens. It is unclear whether Apple's artificial intelligence chips will be embedded in the new 10-year mobile phone. According to reports, the reason why Apple designed artificial intelligence chips separately is to help the application processor (Apple's own design of A series processor) and graphics processor in smart phones and mobile devices to reduce the processing burden and improve device performance. Previously, in addition to the application processor, Apple also used or personally designed a separate chip to complete part of the work, such as in the Apple mobile phone, the company designed a dedicated security chip to store Apple's payment related identity information. In the Apple Bluetooth headset, it also uses a separate chip responsible for data synchronization tasks. It should be pointed out that in the field of artificial intelligence, Apple is currently in a backward situation. Historically, Apple's lack of investment in technology research and development has led to lag behind rivals in many innovations, including virtual reality, augmented reality, autonomous driving, electric vehicles, artificial intelligence, machine learning and more. The backwardness of artificial intelligence technology has led Apple's voice assistant Siri to lag behind its rivals in terms of IQ level and user context voice understanding. Siri has even become the object of deliberate teasing by some Apple mobile phone users. Apple has realized the shortcomings of artificial intelligence. In the past, it has acquired many companies, recruited many talents from outside, and established an artificial intelligence research and development organization in Seattle, USA. One of the important tasks of the organization is to improve the IQ level of Siri. . It is unclear whether Apple's artificial intelligence chip is also designed by Seattle's R&D organization. For artificial intelligence, Apple executives do not disclose much about the media. However, executives such as Cook have clearly confirmed in the past that Apple is interested in augmented reality technology closely related to artificial intelligence, and has already invested. According to many media reports, Apple is developing an augmented reality glasses that will be combined with Apple phones to present users with an augmented reality experience. It is reported that Apple's partner in developing glasses is the well-known lens company Cai Si. However, whether this augmented reality product can be released together in the fall and ten-year mobile phones is still unknown. It should be noted that Apple is transforming chip design work from past external procurement to personal design. Apple has notified the suppliers of graphics chips and power management chips that they will design their own products and will stop purchasing in the future. Affected by this, the share price of several Apple chip suppliers has plummeted. So far, Apple has mainly designed A series processors in smartphones. It is reported that Apple is designing its own graphics processor. By independently designing and producing more processors, Apple can further reduce procurement costs and gain more control over product development. On an occasion last year, Apple Chief Financial Officer Maastrich also confirmed to the media that Apple's R&D spending has increased by $2 billion over the past, mainly because Apple has increased the proportion of chip design, and is also developing various sensors. However, the executive did not disclose in detail which chips Apple is designing. After the design is completed, Apple generally commissioned Samsung Electronics Semiconductor Division or Taiwan Semiconductor Manufacturing Co., Ltd. to produce these chips. Apple does not have a large-scale chip manufacturing plant.

Photovoltaic power generation system is the use of photovoltaic effect to convert solar energy into electricity system, its categories can be divided according to different classification standards. The following is an introduction to the main categories of photovoltaic power generation systems: Solar system panel , solar inverter,Solar lifepo4 battery,Solar lead acid battery, solar controller Foshan Keylewatt Technology Co., LTD , https://www.keylewatt.com
First, according to the access to the power grid classification
Grid-connected photovoltaic power generation system
Definition: Connected to the public grid, the generated electrical energy is input to the grid.
Composition: mainly includes photovoltaic array, grid-connected inverter, load and power grid. Grid-connected photovoltaic power generation systems usually do not need to configure batteries, relying on the grid for energy storage regulation.
Application scenario: Suitable for photovoltaic power generation projects of various scales, including large ground power stations, medium-sized industrial and commercial power stations and small household power stations.
Advantages: It can make full use of the power of photovoltaic array, reduce energy loss and reduce system cost. At the same time, the excess energy can be sold to the power company at a profit.
Off-grid photovoltaic power generation system
Definition: photovoltaic power generation system that is not connected to the public grid and operates independently.
Composition: Mainly includes solar modules, controllers, batteries and inverters (if AC is required).
Application scenario: It is usually built in remote areas far from the power grid or used as a mobile portable power supply in the field, such as remote mountains, no power areas, islands, communication base stations and street lights.
Advantages: not subject to regional restrictions, not dependent on the power grid, wide range of use. It can be installed and used wherever there is sunlight.
Second, classified by energy storage device
Photovoltaic power generation system with energy storage device
Features: The system contains energy storage devices such as batteries, which are used to store excess electric energy to ensure that it can still supply power when there is no light or power grid outage.
Application scenario: Applicable to situations where continuous power supply is required, such as communication base stations, hospitals, and data centers.
Photovoltaic power generation system without energy storage device
Features: The system does not contain storage devices such as batteries, and all the generated electricity is directly input into the grid or supplied to the load.
Application scenario: Applicable to areas where the power grid is stable and the light is sufficient, and where users do not have high requirements on the continuity of power supply.
3. Classification by system structure
Centralized grid-connected photovoltaic power generation system
Features: Mainly use desert and other concentrated areas to build large-scale photovoltaic power stations, power generation directly into the public grid, access to high-voltage transmission system.
Application scenario: Suitable for large-scale photovoltaic power generation projects, such as national power stations.
Distributed grid-connected photovoltaic power generation system
Features: Generally built in the vicinity of users, such as industrial plants, public buildings, residential roofs and so on. The electricity produced is mainly for the user's own use.
Application scenario: Suitable for distributed photovoltaic power generation projects of various scales, with the characteristics of small capacity and low voltage level.
