Founded in 1953, China Railway Signal & Communication Co.,Ltd. (CRSC) is one of China’s earliest specialized railway enterprises. As a large central enterprise directly supervised by the State-owned Assets Supervision and Administration Commission of the State Council, it has developed into a high-tech industrial group featured with intelligent control technologies and a world-leading provider of rail transit control systems.
Its subsidiary, China Railway Signal & Communication Co.,Ltd., was listed on the Hong Kong Stock Exchange in 2015. In 2019, it became the first central enterprise to be listed on the Science and Technology Innovation Board of the Shanghai Stock Exchange, making it the first large central enterprise with A+H dual listings. In 2020, it entered the ranks of central enterprises with total assets exceeding 100 billion yuan for the first time. Currently, the Group comprises 18 major secondary subsidiaries and employs more than 20,000 staff members.
As the designated authority responsible for formulating equipment specifications, technical standards and product standards for China’s rail transit control systems, CRSC boasts a complete industrial chain integrating engineering design for rail transit communication and signaling, R&D of signal equipment for the "three-control" system (network control, space-time control and train control), and engineering technical services. It undertakes the construction of communication and signaling standards at national, industrial and association levels. The Group has established 10 national-level innovation platforms, 3 national railway engineering research centers and 43 provincial and ministerial-level innovation platforms.
It has built up the technical standard system for China’s rail transit communication and signaling, as well as a mature and comprehensive high-speed railway technology system covering trains of different speed classes. Having fully mastered eight core technologies of rail transit operation and control systems with complete independent intellectual property rights, CRSC has driven the historic transformation of China’s rail transit control technologies — from scratch to maturity, from weakness to strength, and from external reliance to full independence and world-class leadership.
Embarking on a new journey in the new era, CRSC keeps firmly in mind the new missions and tasks entrusted to central enterprises by the Party Central Committee. It fully implements the decisions and arrangements of the Party Central Committee and the State Council, and follows the "1241" work philosophy to accelerate industrial restructuring and upgrading.
Targeting the development of major national sophisticated equipment in the field of intelligent control, the Group leverages its strengths in intelligent control technologies to expand the industrial model of "Intelligent Control + N". It focuses on two core business tracks: rail transit and low-altitude economy**, and develops four major intelligent businesses including intelligent rail transit, intelligent low-altitude economy, smart city and intelligent operation.
CRSC speeds up the development of intelligent terminal equipment. Empowered by digital and intelligent technologies, it further consolidates and upgrades the advantages of the full "three-in-one" industrial chain for rail transit, and fully shapes the industrial pattern of "three businesses and one ecosystem" featuring low-altitude airspace management, UAV manufacturing and service & operation to foster a second growth curve. The Group strives to fulfill the three key roles of central enterprises, act as a pacesetter in three fields, and better fulfill its mission of supporting and serving major national strategies.
Exhibits on Display
1. ID-Space Low-Altitude Airspace Intelligent Control System
Built on an advanced intelligent control architecture, this system creates digital airspace corridors and enables real-time dynamic schedule management. It fully adapts to complex flight scenarios, substantially improves the efficiency and safety of low-altitude airspace management, fundamentally addresses the challenges in low-altitude airspace regulation, and provides solid support for low-altitude airspace governance.
2. "One Tower for One City" Cellular-Free Communication System Solution
Combined with public networks, this solution builds a layered and converged public-private low-altitude communication network. By deploying cellular-free communication base stations at high urban locations, it delivers coverage ranging from 120 meters to 3,000 meters, realizing the goal of covering an entire city with a single tower for low-altitude airspace. The system effectively eliminates inter-cell interference of traditional cellular networks, extends transmission distance remarkably, and achieves full-coverage communication across the entire low-altitude airspace, delivering stable and reliable communication services for low-altitude aircraft.
3. CRSC Air Traffic Control Monitoring & Protection System
Composed of radar, optoelectronic devices, directional countermeasure equipment, electrostatic blind compensation devices, integrated radio detection and countermeasure equipment, and a multi-source fusion platform, this system targets low-altitude, slow-speed and small-sized aircraft. It adopts multiple detection technologies for precise monitoring, identifies targets via AI-powered multi-source data fusion, and conducts multi-level countermeasures in a far-to-near operational strategy. It provides planar coverage within a 5-kilometer radius and zonal coverage spanning 6 kilometers.
4. CRSC P4 Pure Electric VTOL UAV System
The P4 vertical take-off and landing (VTOL) fixed-wing UAV adopts a carbon fiber fuselage. With a wingspan of 3 meters and a take-off weight of 15 kilograms, it has a maximum payload of 4 kilograms. Its cruising speed ranges from 65 km/h to 150 km/h, with a maximum flight range of 300 kilometers. Equipped with a tri-sensor pod, it can conduct patrol and inspection tasks in diverse scenarios. Featuring an inverted empennage design, the UAV integrates landing gear and protective structures, embeds antennas into aerodynamic surfaces, and adopts a streamlined fuselage to optimize laminar flow, greatly enhancing lift-to-drag performance. The compound wing UAV hangar is an intelligent system integrating automatic storage, charging, data collection and transmission, status monitoring and mission planning. Deeply integrated with small compound wing UAVs, it enables the UAVs to complete the full closed-loop operations including autonomous takeoff, mission execution, return flight, recovery and data processing in unattended mode according to preset or platform commands, which greatly boosts the operational efficiency and autonomy of the UAV system.
5. CRSCJK-M4 UAV Hangar
Under the control of this hangar, multi-rotor UAVs can perform remote automatic patrol missions. The CRSCJK-M4 hangar supports automatic charging and route planning for UAVs, realizing full-automatic UAV management. Patrol data collected by UAVs is transmitted to the hangar management platform in real time. Combined with AI algorithms, the system completes patrol tasks intelligently throughout the operation.
6. Low-Altitude Intelligent Service & Operation System
Euipped with various UAVs, multi-source sensors and diversified mission payloads, the system collects a wide range of flight data. Supported by artificial intelligence, big data analytics and digital twin technologies, it meets the operational demands of various service scenarios. It can be applied to industrial inspection, urban management, agricultural and forestry plant protection, low-altitude cultural tourism, logistics transportation, emergency command and other fields, helping build a three-dimensional perception system for digital cities and serving numerous industries.Application Scenarios: Rail patrol, high-speed facility inspection, bridge inspection, pipeline inspection, river patrol, forest protection, inspection in enclosed environments, low-altitude logistics.
