With the great advancement of information technology, artificial intelligence has gradually emerged and is widely used in various scenarios such as automated driving, smart home, security monitoring, and medical care. Based on the analysis and forecasting capabilities of big data, AI is regarded as the technology industry. The next vent.
Over the past few decades, we have replaced manpower with automation, which has greatly improved production efficiency and achieved high-volume, low-cost manufacturing. Now artificial intelligence replaces the human brain from the intellectual level. Through speech recognition, visual recognition and machine learning algorithms, the machine can perform some intellectual work, such as customer service, express delivery, reception, administration, sales, finance, etc. It will be replaced by artificial intelligence, and it is only a matter of time before AI takes over human work.
Because artificial intelligence has such great potential, it has become the target of competition among countries. From the level of AI industry development, China and the United States are at the forefront. In recent years, China’s science and technology has developed at an alarming rate, such as the University’s flight and cold. Enterprises such as Wu Ji have already taken the lead in the industry, and China’s goal of a strong country is approaching step by step.
In order to prevent behind China and the United States, the European Commission has planned to invest 20 billion euros in moral artificial intelligence. The cash will be used to promote artificial intelligence research in the private and public sectors, prepare for the progress of socio-economic change, and ensure that its legal and ethical development framework is in place.
Artificial intelligence is changing our world, just like steam engines and electricity in the past, more and more people are seeing this opportunity. The European Commission is pushing researchers to develop the next generation of artificial intelligence technologies and applications that will be developed in collaboration with companies to enable more companies to embrace and integrate into their formations.
Morality is an important topic in the field of artificial intelligence. Artificial intelligence without strict control may bring destruction to human beings. Some famous people such as Bill Gates and Musk have issued warnings that artificial intelligence is not regulated and may lead to The end of the world. The European Commission is taking the right approach to artificial intelligence. The strategy is based on ethics and commitment to responsibility, avoiding premature management pressures, which is critical to positioning Europe to shape the future of AI.
As more and more countries join the AI ​​battle, it is expected to accelerate the commercial application of artificial intelligence and promote the development of society to a higher stage. The use of artificial intelligence can greatly improve the efficiency of the society. For example, we currently use language input several times faster than typing input. This is followed by AI algorithm technology such as speech recognition and semantic interpretation.
Of course, there are advantages and disadvantages. Excessive use of AI may degrade the human brain. Human beings are becoming more and more stupid and machines are becoming more and more intelligent. In the end, human beings may be ruled by machines. People are importing AI into weapon systems. This technology can improve the accuracy of force strikes and enhance the performance of weapons, but it is also a big hidden danger.
When the weapon has the ability to attack itself, it is very likely that it will not be controlled by humans, and finally the scene in which the machine destroys humans in the movie. According to reports, Google has already cooperated with the US Department of Defense to jointly develop artificial intelligence technology for drones. Although it has been resisted by many Google employees, this work continues. It is extremely important to establish ethical standards for AI. Humans need to use AI to improve their quality of life, but also to prevent AI from invading and harming humans.
Optical Line Terminal (OLT)
POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. Etc.) The technology that can provide DC power for such devices while transmitting data signals is a switch that supports Power over Ethernet.
POE is also known as a power supply system based on local area network (POL, Power over LAN) or Active Ethernet (Active Ethernet), sometimes also referred to as Power over Ethernet for short. This is the use of existing standard Ethernet transmission cables to transmit data and data at the same time. The latest standard specification of electric power, and maintains compatibility with existing Ethernet systems and users. The IEEE 802.3af standard is a new standard based on the POE of the Ethernet power supply system. It adds related standards for direct power supply through the network cable on the basis of IEEE 802.3. It is an extension of the existing Ethernet standard and the first international standard for power distribution. standard.
IEEE began to develop the standard in 1999, and the earliest participating vendors were 3Com, Intel, PowerDsine, Nortel, Mitel and National Semiconductor. However, the shortcomings of this standard have been restricting the expansion of the market. Until June 2003, the IEEE approved the 802.3af standard, which clearly stipulates the power detection and control items in the remote system, and connects routers, switches, and hubs to IP phones, security systems, and wireless LANs through Ethernet cables. The method of power supply for points and other equipment is regulated. The development of IEEE 802.3af includes the efforts of many company experts, which also allows the standard to be tested in all aspects.
The IEEE 802.3at standard was formulated in 2005 and promulgated in 2009. The 802.3at standard output power can reach 30W, and the available power at the receiving end is 25.5W.
The IEEE 802.3 working group and various manufacturer alliances launched POH-POWER OVER HDBASET in the industry at the end of 2012.
Using the current 4-Pair four-pair wire technology plus, the bilateral power supply can reach 60-100W power, which can be achieved by using 5 or 6 types of wires. It is used in high-definition video promotion to supply power to 42" LED TVs. According to the new regulations in 2010, the power consumption of 42" LED TVs needs to be less than 70W.
