[Text / high-tech LED Yue Mengdi] Gaogong Research Institute LED Research Institute (GGII) data show that in 2015, the total installed capacity of LED street lamps in China is 4.8 million ç›, an increase of 36%, of which about 2.8 million 出å£, the scale of street lamps About 6.5 billion yuan (the lamp head contains no other), an increase of 7%. In the LED street lighting layout, Chongqing Silian is separated from the traditional LED-intensive Yangtze River Delta and Pearl River Delta, but it is one of the important modules. Chongqing is located in the southern mountainous city of Chongqing. It integrates a special environment with multiple lightning strikes, rainy fog, dust mites, multiple bends, multiple tunnels and road undulations. It has extremely high requirements on the quality and reliability of LED outdoor products. The quadruple in Chongqing has a deeper understanding of LED street lights. It is understood that the four street lights and tunnel lights have a number of patents, from heat dissipation technology to secondary optical technology, have reached the domestic leading level. The modular design ensures shorter lead times and easier maintenance and repair. At the same time, it has multiple protection functions such as over temperature, over voltage and over current. Yu Hongbo, director of the Fourth Marketing Department, told Gaogong LED that it is located in the “One Belt and One Road†bridgehead in Chongqing. It is supported by LED's industrial structure and supported by the state. In the western region, the development and demand are gradually expanding. Europe. Intelligent LED street lights are an important module to cater to the country's construction of “smart citiesâ€, but traditional street lighting systems cannot achieve remote, real-time, single-point, non-centralized group management, and no data monitoring. The LED lighting control system based on the Internet of Things not only solves the above problems, but also realizes the functions of intelligent operation and automatic repair of the street lamp system. "We are committed to improving and expanding the functions of existing intelligent control systems, from single-lamp, loop, centralized power supply systems to integrated intelligent systems such as environmental monitoring, video surveillance, and network services," said Yu Hongbo, using China Silian Group. Technological advantages, engineering capabilities, financing platforms, and high-quality and efficient products provide differentiated quality solutions. Under the manufacturing of Chongqing, Silian benefited from the development strategy of Chongqing's electronic information industry and the local convenience of rapid economic development. At the 2015 High-tech LED Annual Meeting, industry insiders can listen to the four-linked "LED lighting under Chongqing".
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.

In 1995, the more high-speed SCSI-3, called ultrasci, was born, and the data transmission rate reached 20MB / s. It increases the synchronous transmission clock frequency to 20MB / s and improves the data transmission rate. If 16 bit wide mode is used, the data transmission rate can be increased to 40MB / s. This version of SCSI uses a 68 pin interface, which is mainly used on hard disks. The typical characteristic of SCSI-3 is that the bus frequency is greatly increased and the signal interference is reduced to enhance its stability.
There are many models of SCSI-3. Ultra (FAST-20) has a transmission frequency of 20MHz, a data bandwidth of 8 bits and a transmission rate of 20MBps
Ultra wide has a transmission frequency of 20MHz, a data bandwidth of 16 bits and a transmission rate of 40mbps
The transmission frequency of ultra 2 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 80 Mbps
The transmission frequency of ultra 160 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 160 Mbps
The transmission frequency of ultra 320 is 80MHz, the data bandwidth is 16 bits, and the transmission rate is 320mbps
The transmission frequency of ultra 640 is 160MHz, the data bandwidth is 16 bits, and the transmission rate is 640mbps
