In the context of large-scale construction of highways, high-speed railways, and urban rail transit, the number of long tunnels continues to increase, raising higher demands for communication assurance during both construction and operation phases. The Mesh self-organizing network communication integration solution launched by Shenzhen Zhijing Technology Co., Ltd. addresses practical pain points in tunnel scenarios such as “lack of public network coverage“, “emergency communication interruptions“, and “difficulties in personnel and equipment management“. It provides a practical, easily deployable, and highly compatible technical path.
First, during the early stages of tunnel construction, the cost and duration of traditional wired network deployment are high, and it is difficult to dynamically extend with the construction face; meanwhile, public network signals are almost impossible to cover due to tunnel structure obstructions. This solution quickly builds a wireless communication backbone network covering the construction area through a chain deployment of Mesh self-organizing network integration communication gateways, without relying on a central server, supporting 4G public network access, WiFi coverage, and voice intercom integration, effectively solving the communication isolation problem between sections, enabling remote video supervision, equipment operation process recording, and personnel operation collaboration.
Secondly, in tunnel operation or emergency scenarios (such as collapses or fires), conventional communication is prone to interruption. At this time, the Mesh network, with its decentralized, self-healing, and multi-hop relay characteristics, can quickly rebuild local communication links using mobile nodes such as portable command boxes and radio stations. The smart terminals worn by rescue personnel can still achieve voice intercom, one-click alarm, and video return functions even without public network or core network conditions, providing real-time audio and video information to the command center, supporting visual scheduling and scientific decision-making.
Additionally, the solution integrates centimeter-level precise positioning capabilities, enabling location tracking of construction and maintenance personnel through badges, wristbands, or device tags, electronic fence alarms, historical trajectory tracing, and attendance management, thereby enhancing safety management efficiency. At the same time, the system is compatible with intercom devices of different brands, frequency bands, and channels, avoiding redundant investments by users and lowering the system integration threshold.
This solution does not pursue flashy technology but focuses on the communication necessities throughout the entire lifecycle of tunnels — from efficient collaboration during the construction phase to emergency support during the operation phase, providing stable, practical, and scalable communication infrastructure to effectively enhance the safety management level and emergency response capability of tunnel projects.
