Page view

  On June 30, 2017, the long day of Changchun people, the official operation of Metro Line 1 marks that this 200-year-old city has finally entered the subway era! The operation of the subway is inseparable from the construction and rail transit personnel. Hard work and hard work, maybe you don't know that the super-engineering of Metro Line 1 is also indispensable to the silent payment of Cedar Electronics.

  The 15 subway stations of Changchun Metro Line 1 and the 61 subway stations in a total control room have been added to the “completely ready to go” of each subway station. From this day on, 61 LED displays began their historical mission in various subway stations. These products, which were born from Changchun Xida Electronic Technology Co., Ltd., are like the children of Cedar engineers. These displays were independently developed by them, and the entire R&D and production process was shared for more than four months. In order to catch up with the construction period, the team of more than 30 people worked overtime almost every day. Compared with the current display of the Changchun light rail platform display, the display is not only clearer, but also technically superior and innovative. The subway station display has the function of “offline display”: there is an offline control card in each display, and there is a running system in the card, just like a small computer. After the command from the general control room of the subway, no wires need to be connected, and only through the wireless connection, each display can display the information that the main control room needs to display. At the same time, the display can capture the current image anytime and anywhere and return the image. If the content on the display is incorrect, the main control room staff can correct it at any time.


 After commissioning, the factory will display the LED display

  The 15 stations of Metro Line 1 are all underground stations. The lighting and signs in the station are especially important for the daily travel of the citizens. Cedar Electronics successfully broke the metro industry, the monopoly of foreign lighting companies' products and technologies, and applied and served the Changchun Metro. Among them, the platform lighting adopts the special lighting fixtures of Changguang Xida Metro. The products are aimed at the special underground use environment of the subway and the ten-year life requirements of the lamps. All of them adopt seamless welding and outdoor polyester powder spraying process to solve the technical problems of sealing, dustproof, anti-corrosion, anti-vibration and anti-shedding of subway lamps. All the lamps adopt the front maintenance installation structure, the products are easy to install and easy to maintain, and meet the specific needs of the lamps and lanterns maintenance in the metro industry. The photoelectric performance of the products exceeds the foreign brands. The products have outstanding advantages of energy saving, environmental protection, long life and maintenance-free. It is combined with the subway platform to form a simple, bright, soft and even use effect, which is the perfect combination of art and function.
