Description

Technical Field

[0001] This application relates to the field of field emergency rescue, and in particular to a field emergency rescue kit. Background Technology

[0002] As a core infrastructure for energy transmission, power transmission lines traverse complex geographical environments such as uninhabited areas, high-altitude mountains, and deserts. In high-altitude areas, public network coverage is less than 30%, and over 60% of monitoring points lack access to mobile networks, posing significant safety hazards to field operations such as power transmission line inspections. If inspection personnel encounter emergencies such as heatstroke or animal attacks, they are at risk of being unable to seek help or experiencing delayed rescue efforts. Therefore, developing emergency rescue kits suitable for this scenario is essential.

[0003] The existing wilderness rescue kit is designed specifically for environments without infrastructure. Its core functions include emergency communication, material storage, and environmental adaptation. This type of equipment is mainly used for power / communication inspection, and can also serve multiple wilderness scenarios such as outdoor exploration, forest ranger operations, and geological disaster rescue.

[0004] However, existing emergency rescue kits have significant technical flaws, making it difficult to meet the needs of complex rescue scenarios. Emergency communication modules generally face bandwidth bottlenecks. Due to the low rate of BeiDou short message service, a single message is limited to the number of Chinese characters, allowing only text information to be transmitted. This prevents the transmission of multi-dimensional data such as injury photos and videos, and the intermittent transmission results in poor real-time performance. Satellite phones only support voice calls, and data transmission requires additional expensive satellite services, hindering large-scale application. LoRa self-organizing networks are susceptible to terrain-related electromagnetic interference, affecting the efficiency of collaborative rescue. Consequently, the design of existing emergency rescue kits is not fully adapted to the terminal usage habits and information interaction needs of field operations. Design flaws in interface protocol compatibility and ease of operation lead to insufficient efficiency in rescue information exchange, a high risk of operational errors, and an inability to meet the core requirements of real-time information transmission and operational reliability in field emergency scenarios.
