not long ago, it was the fourth anniversary of the official launch of the beidou-3 global satellite navigation system. this system has achieved seamless coverage around the world and is the result of decades of unremitting exploration and hard work by the country. from breaking the western technology monopoly to achieving comprehensive independent innovation, beidou-3 has not only consolidated the core position of basic navigation services, but also demonstrated its irreplaceable strategic value in many key areas. against this background, as a leader in the global space-time information industry, unistrong has actively responded to the needs of the times and tailored the "beidou+" tower deformation monitoring system for railway safety.
the "beidou+" deformation monitoring solution deeply explores the innovative application of beidou's high-precision services in the field of tower deformation monitoring. by accurately improving monitoring efficiency, it builds an indestructible line of defense for railway safety.
unistrong's "beidou+" urban construction service application
china's infrastructure construction has attracted worldwide attention, from towering iron towers to majestic dams, to spectacular bridges stretching for dozens of kilometers. they are not only a symbol of national strength, but also an indispensable guarantee for the lives of the people. however, with the continuous changes in the natural environment and the passage of time, the structures of these facilities may undergo slight deformations, causing unpredictable safety hazards.unistrong's deformation monitoring solution integrates beidou high-precision services, multi-sensor fusion technology and ground auxiliary equipment to achieve all-weather, continuous and automated monitoring of key facilities such as bridges, dams, slopes, towers, tailings ponds and large buildings.。the monitoring content comprehensively covers subtle changes such as displacement, deformation, settlement, etc. the monitoring system is not only highly accurate, but also has an immediate response early warning mechanism, which can effectively reduce or even prevent the occurrence of safety accidents, providing a solid guarantee for the safe operation of infrastructure.

tower deformation monitoring system helps safe railway operation
railways are a key national transportation infrastructure and a major artery for national economic development, occupying a strategic position in the national economic system. as the core carrier supporting railway signal lights and communication base stations, the stability and reliability of the tower are indispensable cornerstones for ensuring safe and smooth railway transportation. in december 2021, the national railway administration issued the "14th five-year plan for railway science and technology innovation", proposing to "vigorously promote the deep integration of cutting-edge technologies such as beidou satellite navigation with railway technical equipment, engineering construction, transportation services and other fields, strengthen the research and development and application of key core technologies for intelligent railways, promote the collaborative sharing of big data, promote the development of the digital economy in the railway field, and improve the level of railway intelligence."
the tower deformation monitoring system launched by unistrong deeply integrates the precise positioning capability of the beidou satellite navigation system and uses beidou's high-precision monitoring technology as its core driving force.the system widely deploys beidou monitoring terminals on communication towers along the railway lines to achieve real-time and high-frequency collection of tower displacement data. subsequently, these data are instantly transmitted to the central server through advanced communication modules. the server uses pre-built data analysis models and combines real-time collected multi-dimensional meteorological data such as wind force, wind speed, wind pressure, humidity, and temperature to conduct rapid and accurate comprehensive analysis.
the system presets alarm thresholds according to strict technical specifications. once the tower deformation exceeds the safe range, the alarm mechanism is automatically triggered and emergency information is quickly distributed to relevant personnel to ensure that the problem is responded to and handled immediately.in addition, the system also has powerful data analysis capabilities, can integrate various types of sensor data, and make forward-looking predictions on the future tilt and displacement trends of the tower, providing a scientific basis for formulating safety precautions in advance, and effectively assisting the auxiliary decision-making process in digital railway operations.
tower base differential reference station installation
ironthe tower monitoring system consists of a collection unit, a monitoring unit, a data communication network, a tower monitoring server, a management terminal and other components.relying on the high-precision positioning service provided by the railway beidou application service platform, a tower tilt monitoring system based on beidou high-precision technology is built.
the acquisition unit includes beidou differential high-precision receiver, beidou receiving antenna, micro-meteorological instrument, etc., which provide the acquisition of parameters such as tower inclination and horizontal/vertical displacement, tower base settlement, wind speed level/direction, tower ambient temperature and humidity, etc. as shown in the figure below, by installing high-precision beidou receiving antennas on the top, middle and base of the tower, they are connected to the beidou differential high-precision unistrong e2023-5a receiver via rs485 bus. the monitoring data is transmitted back to the station monitoring center for early warning information release.

the monitoring unit is deployed in the communication room of the tower work area to complete data collection and processing, and then the communication module (wired and wireless) interacts with the monitoring center server. after receiving the sensor data, the monitoring unit repackages and uploads it to the monitoring server, reports the alarm information in real time, and completes the local management of the sensor, local storage, and remote software upgrade and update.
the tower monitoring server is deployed in the station section communication room. it remotely manages each tower through the monitoring unit and classifies, processes, stores, displays and outputs the monitoring data and alarm data.
unistrong tower deformation monitoring system
in summary, unistrong's tower deformation monitoring system not only significantly improves the level of informationization and intelligence in railway operation and maintenance, but also lays a solid foundation for ensuring the long-term stable operation of the railway network and the safety of passengers' travel.
wide application of "beidou+" deformation monitoring system
unistrong's high-precision millimeter-level deformation sensing and monitoring solution is a deep extension of the "beidou+" high-precision application in the field of deformation monitoring. the system can also be expanded to supportvehicle/personnel location management, high-precision 2d and 3d maps, ai intelligent recognition, smart iot terminals, refined management of equipment and facilities, etc., to meet users' expanded application of various precise space-time scenarios, reduce the complexity of urban digital transformation, and provide a solid foundation for high-quality development of the industry.
at present, unistrong's deformation monitoring system has been successfully infiltrated and widely used in many critical fields such as geological disaster early warning, cultural heritage protection, bridge health monitoring and bridge settlement assessment, mine safety supervision, dangerous and old house status monitoring and dam safety management, and has achieved remarkable results. with the continuous iteration, upgrading and popularization of technology, unistrong is full of confidence and determination to use scientific and technological power to build a solid line of defense for the safety of people's lives and property, and actively lead the society towards a safer, more stable, green and sustainable future development direction.
