The Internet of Things IOT responds logically after Big Data. Compared to the invisible big data, the Internet of Things is tangible, and it is also the first industrial revolution of mankind from the 19th century. After that, for the first time, consider the sustainable industrial upgrading of the earth.
　　 Why is the Internet of Things?
　　 Because of big data. First of all, including these three stages is called big data: 1. Statistical analysis 2. Prediction and recommendation 3. Intelligent optimization. Statistical analysis is by far the general public's understanding (or misunderstanding) of big data, while the latter two require a large amount of uninterrupted data collection and classification to help operators/managers provide effective predictions or recommendations, based on The 3-5 year forecast recommends implementation results, non-stop collection of cases, and ultimately the ability to automatically optimize and allocate resources.
　　 The finer the data feedback, the higher the accuracy of the analysis statistics. Big data is now like a broken piece of music, with a lot of details lost in the middle, and the Internet of Things can help fill in the details of the loss of the score. Because the information that human beings now has is not enough to support big data into a powerful auxiliary tool, so that people in all industries, as well as parts of physical assets can help provide data, it becomes the basic work of big data. .
　　 Based on the different strengths and strategies of different countries, the Internet of Things revolution has different applications in different countries. For example, Germany was first perceived and started. The government called it Industry 4.0. Since last year, it has drafted a white paper for its intelligent factory production line. In the United States, it focuses on smart transportation and smart grid. China is targeting Put it in a smart city.
　　 The first industrial revolution was the invention of the steam engine; the second industrial revolution was the use of machinery to help the labor force of the production line, and labor grading; the third industrial revolution began to use electricity and robots to help a large number of automated production; the fourth industry The revolution is to use countless sensors to help collaborative factories around the world to predict and optimize production, avoiding scarcity and excess.
　　 This is why the Internet of Things is placed in the next round of important strategic directions in various countries. The Internet of Things will establish the networking communication capabilities of all physical asset components. Although the Internet of Things and the Internet complement each other, they are far different in scale. First of all, hundreds of millions or even billions of physical assets, control and data throughput processing capabilities will become a big test, not to mention the needs analysis of upstream and downstream personnel.
　　 For example, in a province that wants to implement a smart grid, the province has already had a large number of smart meters in various households, but the smart meters that its power plants can handle can only retrieve hundreds of thousands of meter data at a time, and only one hour. Take one time, the utilization rate can be said to be miserable.
Therefore, the subordinate IoT world is not only the work of the hardware engineering industry, but also the software solutions and experience design professionals.
Emergency LED drivers are designed specifically for light fixtures . These emergency backup drivers regulate the power supplied to the LED fixture the same way normal drivers do , but they operate off of a battery instead of line voltage . Because they operate off a battery the light output isn't as bright as the fixture normally would produce , but it will be just enough in an emergency situations . Most of our emergency LED drivers have a maximum emergency operation time of 120 minutes .
