Actual case presentation raises concerns Railway construction investment accelerates and opportunities in the display and control industry China Railway Corporation (formerly the Ministry of Railways) Dispatching Command Center Guangzhou Metro Line 1, 2, 8 Control Center A PON consists of an Optical Line Termination (OLT) at the communication company's office and a number of Optical Network Units (ONUs) near end users. Typically, up to 32 ONUs can be connected to an OLT. The passive simply describes the fact that optical transmission has no power requirements or active electronic parts once the signal is going through the network.

This time, Weichuang debuted the DLP mosaic display system and the IDB intelligent display terminal. High-resolution small patchwork DLP display system, multi-functional integrated, high-definition IDB intelligent display terminal makes the participants shine, attracting many professionals in the industry, such as the National Transportation Association, more than 20 subways nationwide The relevant person in charge of the company waited until the booth to conduct in-depth understanding and communication. 
In front of the big screen of booth 3400 in Hall 3 of China International Exhibition Center, the scenes on the screen attracted many participants to stop watching. Combined with the practical application of Beijing Metro Line 8, Witron demonstrated to the participants the application of the large-screen splicing display system in the subway command and dispatch center and video surveillance, and more intuitively showed the participants the Wistron large-screen splicing display system. The value of application in rail transit. The real application case strongly confirms the comprehensive strength of Weichuang. It is understood that Wistron's products and application systems have been well received by many participants and reached a cooperation intention with individual customers.
For China, China has raised the amount of railway fixed assets investment in 2014 from 630 billion yuan to 800 billion yuan, of which 530 billion yuan is for railway infrastructure investment. A few days ago, Morgan Stanley announced that this year's uncompleted investment in China's railways will reach an all-time high of nearly 1.8 trillion yuan, equivalent to 2.8 times the estimated scale of railway infrastructure investment this year.
With the rapid development of the rail transit industry, the safety requirements for line operation will also become higher and higher. It is necessary to grasp the train operation and various driving equipment conditions in real time, and timely receive all kinds of information that endangers driving safety and make correct The judgment and decision-making process quickly and effectively handle various abnormal situations to ensure the normal order and safe operation of transportation.
This is a development opportunity for the large-screen splicing display industry that can provide a good display management platform, and it is even more so for the cultivating of the rail transit industry for many years.
At present, Weichuang has implemented more than 120 rail transit industry projects in China, including the China Railway Corporation (formerly the Ministry of Railways) dispatching command center, Shanghai dispatching command center, Shenzhen Metro, Guangzhou Metro, Beijing Subway, Shanghai Hongqiao Hub. Other important projects, such as command and dispatch center, monitoring center, marshalling station and emergency command, are used to protect the safe operation of China's rail transit.
With more than 10 years of attention and expansion of the rail transit industry, Witron has accumulated a lot of experience in this industry, and has repeatedly updated the record of “the first screen of rail transitâ€:
In 2003, he won the bid for the Shenzhen Metro and built the “first screen of global rail transit†at that time;
In 2010, won the bid for Guangzhou Metro Line 128 to create the “first screen of urban rail transitâ€;
In 2011, the company won the bid for the OCC Joint Dispatching Command Center of Hong Kong Metro, setting a record for “the largest LED light source DLP display in the worldâ€.
In 2012, the former Ministry of Railways provided a large-screen splicing display system with a total of 152 LED light source 80'' display units, once again refreshing the record of "the first screen of global rail transit"...
At present, Weichuang has implemented more than 120 projects in the rail transit industry in China, including the former Ministry of Railways, Shenzhen Metro, Guangzhou Metro Line 128, Beijing Subway, Shanghai Hongqiao Hub and other important projects, involving command and dispatch centers, monitoring Applications such as the center escort the safe operation of urban rail transit.

N-NET supply Ethernet Passive Optical Network (EPON) and Gigabit-Capable Passive Optical Network(GPON),EPON and GPON are popular versions of passive optical networks (PONs). All PON systems have essentially the same theoretical capacity at the optical level. The limits on upstream and downstream bandwidth are set by the electrical overlay, the protocol used to allocate the capacity and manage the connection.
The 12th China International Railway Technology and Equipment Exhibition (MODERN RAILWAYS 2014) was held on October 28-31, 2014 at the China International Exhibition Center in Beijing. Guangdong Weichuang Video Technology Co., Ltd. (hereinafter referred to as Weichuang) joined hands with China Railway Communication Signal Co., Ltd. (hereinafter referred to as Tonghao) to participate in this exhibition. Weichuang demonstrated the actual case of rail transit in the exhibition and shared with visitors. The application results of Weichuang in the rail transit industry.
