CCTV news: Shanghai Metro Line 15 opened for trial operation on January 23, the longest kilometer rail transit line and the highest level of fully autonomous driving in China at a time.

Value significance

Shanghai Metro Line 15 plays a strong role in strengthening the service between the western inner and outer ring lines of Shanghai, driving the development of the regions along the lines, collecting and transforming the passenger flow of the intersection railway lines along the railway lines, and balancing the network passenger flow.

Smart line

After Line 15 opens, trains equipped with intelligent operation and maintenance system will be used, and the vehicle operation status will be transmitted to the operation and maintenance platform in real time to realize automatic driving and create a new mode of intelligent operation and maintenance of urban rail trains.

As the highest rail transit line of automatic driving in China, the whole line uses Yantai persistent CJ-M9300IIIG system, which is a high-performance time synchronization system with ARM + FPGA architecture, and provides high-precision and high synchronization timing service for more than 20 intelligent systems of high-speed railway, including scheduling, signal, security, broadcasting, ticket sales and customer service and so on.

The help of Chijiu


As a clock server representing the highest level in China, CJ-M9300IIIG has adopted Yantai's lasting and unique core technology and patent algorithm by receiving the Beidou satellite signals, and its timing accuracy, reliability and stability have all reached the international first-class level.The output synchronous signals include: NTP, PTP, IRIG-B code, serial port to time message, and pulse signal 1PPS, etc., which can meet the multi-scene time requirements.

As a leading enterprise in the time synchronization system in China, persistent Watch will continue to adhere to the corporate spirit of integrity, innovation, responsibility and gratitude, continue to provide quality products and services for the society, and make new contributions to the development of China's rail transit.
