Description

Technical Field

[0001] The present invention relates to the technical field of communication engineering, and in particular to a high-precision charge-discharge balance intelligent positioning system integrating Beidou and ultra-wideband technologies. Background Art

[0002] Construction workers face many safety risks at construction sites, especially those in high-altitude areas. These include the risks of falling, explosions, and other accidents caused by high-risk construction such as aerial work, aerial work, and blasting work; construction risks such as high slope collapse, deep foundation pit collapse, and cavern collapse caused by complex terrain; natural disaster risks such as frostbite and avalanches caused by outdoor environments and extreme climates; and health risks such as high-altitude pulmonary edema and high-altitude cerebral edema caused by high-altitude environments. Large-scale engineering construction, such as hydropower projects and mining projects, is large in scale and has complex construction processes. It involves multiple professions and types of work, and coordination and management are difficult. At the same time, the quality of construction workers varies greatly, and some personnel lack the necessary safety awareness and skills. Once a safety accident occurs, the consequences are disastrous. The traditional personnel management model mainly relies on limited management personnel for on-site management, which cannot effectively cover all construction processes and every person on site. There are safety management loopholes, low efficiency, incomplete and inaccurate data, and other problems.

[0003] In recent years, with the advancement of positioning technology, the positioning of personnel and equipment has gradually been implemented on construction sites to assist with project supervision. Currently, commonly used positioning technologies in the engineering field include satellite positioning, ultra-wideband (UWB) positioning, and Bluetooth positioning. The Beidou satellite navigation system not only provides positioning, navigation, and timing services, but also features SMS messaging, making it particularly suitable for emergency communications in areas without network coverage, such as oceans and deserts. The Beidou system's service accuracy and reliability are competitive among global satellite navigation systems, providing a crucial time and space benchmark for industries such as hydropower engineering. Ultra-wideband (UWB) technology is a wireless communication technology widely used in short-range communications due to its high-speed data transmission capabilities and low power consumption. UWB technology achieves high-precision time measurement by sending and receiving pulse signals with extremely short time intervals, thereby providing precise positioning. Beidou satellite navigation system positioning technology is typically used outdoors and above ground. However, in complex environments such as factory buildings and underground caverns, UWB technology can be used to supplement high-precision location information acquisition to address issues such as increased interference and non-line-of-sight transmission caused by obstructions such as mountains and buildings.

[0004] Current positioning systems primarily utilize a single mode (Beidou or UWB), lacking intelligent switching mechanisms for indoor and outdoor use. Furthermore, they suffer from insufficient positioning accuracy and high base station density, leading to high investment, difficulty in operation and maintenance, and high costs. User terminal devices still need to improve in terms of battery life (requiring frequent charging) and lightweight design. Furthermore, existing systems are relatively ineffective in integrating positioning data with construction data, primarily focusing on visualization and display, and lack effective decision-making support capabilities. Summary of the Invention
