Monitoring and warning

The rapid development of the national economy requires strong support from a large number of basic production activities. Automated safety monitoring of mines, geological hazards, bridge deformation, water conservancy and hydropower, and oil and gas pipelines is especially important in production activities. The use of high-precision RTK positioning equipment, multi-functional intelligent sensors, and the Internet of Things can comprehensively improve the safety and supervision levels of relevant enterprises, and enhance the ability of enterprises, society and the government to respond early warnings of safety hazards.

GIS Mapping and Surveying

GIS provides a visual way to combine and analyze geographic data with other data sets and tools to help users better understand issues and opportunities in the decision-making process and develop the best solutions. GIS can accurately capture and store geographic location data and combine it with other data sets. This capability is extremely important for various fields of application, such as environmental management, urban planning, emergency response, and agriculture. With the continuous development and innovation of technology, the application scope of GIS will continue to expand and deepen.

Position and orientation

By satellite navigation positioning systems, ground-based augmentation systems, real-time kinematic positioning technology and inertial navigation technology, the operating status of various means of transport can be monitored in real time, scientifically dispatched and accurately commanded. At the same time, by using 4G/5G networks, WiFi and Bluetooth communication technologies to update management data in real time, means of transport can enter the era of precise management.

Digital construction site

Digital construction enables full life cycle management of engineering projects by integrating high-precision positioning technologies, mechanical control algorithms and AI image recognition capabilities. Through three-dimensional visualization, high-precision maps and other means, complex engineering information is transformed into measurable and displayable digital data. BIM technology and mechanical equipment control technology are used to realize the collection, process supervision, resource scheduling and information release of full-process information of people, objects, vehicles and construction machinery under the construction site scene.

Indoor Location

With the advancement of positioning technologies such as WiFi, Bluetooth, UWB and Zigbee, high-precision indoor positioning systems have received widespread attention. A single technology alone can no longer meet the needs of all positioning scenarios. Therefore, the "integration of multiple technologies" has become an inevitable trend in the development of positioning technology. From UWB to Bluetooth AOA/AOD to 5G, positioning technologies continue to derive, driving continuous advances and popularization of positioning technology.

DIFFICULTIES AND CHALLENGES

People management is a perennial problem

Due to the complex construction site environment and the lack of on-site visualization tools for personnel, it is very difficult to manage personnel on duty. In addition, problems such as inadequate patrol control, improper operation control, untimely emergency rescue, irregular operation management, and incomplete visitor management often occur. The implementation of patrol tasks is not in place, the patrol content is simple and lacks authenticity, and the patrol data cannot be saved and viewed effectively; the approval is not strict, the procedures are cumbersome, the on-site supervision is not in place, and the progress of the work cannot be tracked in time; lack of operating status monitoring, emergency situations cannot obtain rescue in time, and emergency evacuation lacks visualization tools; key areas and positions lack supervision, personnel on duty and vehicle management are irregular; daily visitors and daily operation and maintenance personnel management lack comprehensive and clear data, and it is easy to make mistakes and omissions.

Vehicle management is difficult

The complex terrain and changing routes of construction sites make real-time positioning difficult; the large number of widely distributed vehicles are difficult to supervise and are prone to congestion and accidents; the complex road environment is prone to safety risks; frequent vehicle access, complex routes and time limits lead to low transportation efficiency; it involves a large amount of data collection and processing, and the system data set integration is difficult.

The efficiency of traditional machinery is low

Traditional earthwork construction requires precise excavation, and surveyors must repeatedly verify it. If it is not excavated enough, it needs to be supplemented, and if it is over-excavated, it needs to be backfilled, which will seriously affect construction efficiency and pose safety hazards to auxiliary personnel around the excavation equipment. Although experienced drivers play an indispensable role in excavation, in some special working conditions such as night construction and underwater operations, even highly skilled "old craftsmen" need to rely on expensive surveying equipment and personnel assistance. Pile foundation construction requires an accurate grasp of positioning points, but at least two people are required to complete the layout process, and the assistance of a worker is also needed. In such an open environment as the construction site, with many personnel and equipment, it is easy to confuse and lose pile positions by relying solely on manual surveying and recording, resulting in time-consuming layout positioning and repeated verification and correction processes, directly affecting the progress of the project.
