Description

Technical Field

[0001] This utility model relates to the field of adaptive wireless communication technology, and more specifically to an adaptive wireless communication device for a construction site safety inspection robot. Background Technology

[0002] With the rapid development of intelligent construction and construction robot technologies, and the continuous improvement of informatization and intelligence levels at construction sites, safety inspection robots are increasingly being applied to safety monitoring and inspection tasks during construction processes. These robots replace or assist safety officers in safety inspections, environmental monitoring, and hazard identification. Such inspection robots typically rely on wireless communication technology to interact with control centers, cloud platforms, other inspection robots, and other intelligent terminal devices. This includes uploading sensor data, task scheduling, emergency response, issuing control commands, and real-time data exchange among multiple robots. However, the complex environment and constantly changing structures at construction sites present significant limitations in such scenarios due to the limitations of traditional wireless communication methods.

[0003] The shortcomings of existing technologies are as follows: 1. Conventional cellular mobile communication networks (such as 4G and 5G) at construction sites often suffer from severe signal attenuation, numerous coverage blind spots, and even complete communication interruptions. This is due to the large amount of reinforced concrete walls, the accumulation of construction materials, and the complex spatial layout within the building structure, making it difficult for external wireless signals to penetrate into the building. 2. In actual construction, the construction progress is continuous, the internal walls of the building are not yet fully formed, the wall structure changes constantly with the construction progress, or the walls need to be plastered, painted, or tiled, making it impossible to permanently fix the communication device in place. The power supply conditions at the construction site are complex and have high safety requirements. Temporary circuit layouts pose safety hazards, and communication equipment needs to be frequently moved due to environmental changes. Battery power supply will also affect its efficiency due to frequent replacement or maintenance. 3. Due to the influence of internal walls, reinforced concrete structures, and aluminum alloy formwork in concrete engineering, wireless signals are prone to significant attenuation and multipath interference, leading to unstable communication or even interruption, making it impossible to guarantee the real-time communication needs of inspection robots inside the construction site.

[0004] Therefore, there is a need to provide an adaptive wireless communication device for a construction site safety inspection robot to solve the problems mentioned above. Utility Model Content
