Intelligent high-speed train combined with Internet of Things technology A few days ago, China's first intelligent high-speed train prototype was completed and rolled off the assembly line at CSR Qingdao Sifang Locomotive Co., Ltd. Editor's interpretation: According to the current development stage of China's smart transportation and connected vehicle industry and the actual situation of market application, as well as the strong support of policies, industries related to smart transportation and connected vehicles will develop rapidly along the industrial chain. Such as intelligent transportation systems, navigation and positioning services, perception devices like high-end sensors, wireless communication networks, etc. Mozilla Firefox OS mobile phone officially enters the retail market to attack the low-end market After nearly two years of development, Mozilla today officially launched the Firefox OS phone for the retail market. At the same time, the company has also opened the developer payment function to provide convenience for developers interested in selling applications or selling content in applications. Editor's interpretation: Some people in the industry pointed out that Mozilla ’s Firefox OS is certainly facing many “uphill battlesâ€, but from now on, Firefox OS mobile phones are no longer a kind of “fogware†(that is, products that have been promoted before the development is completed, And these products may not come out at all). Firefox OS phones may not be impressive, because Mozilla mainly focuses on the low-end market to start to increase the momentum of business growth, but in view of the severe competition in the high-end market, Firefox OS phones should not Bring a big surprise. Although this does not mean that there are not a large number of low-cost mobile phones on the market, if Mozilla wants to build an ecosystem in the current mobile market that is already a "deep trench", then there is undoubtedly a long way to go go. Rare earth prices rose across the board Editor's interpretation: Rare earth prices may remain at a high position, but due to the cold downstream demand, rare earth prices may be difficult to get out of the continuous rise. Electronic devices are like phosphors in LED lighting. Rare earth products do not account for too much of their cost, and have a limited impact on the price of electronic devices. The world's richest man invests heavily in latent speech analysis industry Mobile application developer Shazam recently received a total investment of US $ 40 million from Forbes' 2013 richest man, Carlos Slim. The company is known for applications that help music lovers identify songs, and has said it may seek to go public next year. Another foreign media reported that Apple is testing the local offline version of voice input. Editor's interpretation: This shows that the voice analysis industry is becoming a hot spot for all parties to grab the beach and has broad development prospects. Especially with the rise of smart phones and wearable devices, the demand for voice analysis will gradually increase. Voice recognition technology and intelligent processing technology are the core. Related companies in China include HKUST Xunfei, which has the world's most advanced Chinese speech synthesis and recognition technology; Tors is the leader of Chinese unstructured information processing and masters the core technology of Chinese intelligent processing. Three solar companies filed for bankruptcy in a week According to foreign media reports, three solar energy companies filed for bankruptcy in the past week. This is another new wave of bankruptcy after solar power giants such as Q-Cells and the bankruptcy of Wuxi, China, declared bankruptcy when Q-Cells fell sharply in the last round. The three companies that filed for bankruptcy are Germany's Conergy and Gehrlicher Solar, and Hawaiian solar company Hoku. All three solar companies attribute their collapse to fierce competition in the global photovoltaic market. Editor's interpretation: Although the crisis in the photovoltaic industry, which has lasted for nearly two years, showed signs of recovery in the first half of the year, the polysilicon link in the "severely affected area" of the crisis is still on the front line. According to the latest research report of the China Nonferrous Metals Industry Association Silicon Industry Branch, currently only 4 of the 43 domestic polysilicon companies are barely maintaining their construction, and the capacity utilization rate of these 4 companies has dropped to less than 30%. Half a year also continued to show a downward trend. The sluggish demand caused by the economic downturn is the main factor, which is also the result of the unplanned blind expansion of the solar industry in the early stage. Presumably, Chinese companies will feel more sad under the double-anti-investigation.
