确保隧道工人的重要安全沟通

澳大利亚电网

澳大利亚电力供应商Ausgrid开始了一项耗资 8 亿美元的雄心勃勃的升级项目。

Ausgrid 通过新南威尔士州政府无线电网络 (NSWGRN) 使用单工无线电频道来保持部署在各个检查站的维护人员和在隧道内更深处工作的团队之间的开放式通信。但是这种方法有很大的缺点和局限性。

Ausgrid 联系了康普，以制定和部署更有效的沟通策略。

分布式覆盖和容量解决方案团队建议由 ION-M® 智能光网络提供额外的覆盖 - 一种无线电光纤、宽带、与技术无关的中继器平台。

该平台重新广播来自 Ausgrid 两个变电站的专用基站的 NSWGRN 信号。 ION-M 还支持隧道内的 Wi-Fi 访问，为 Ausgrid 提供了一套全新的通信和效率机会。

• The implementation of the ION-M across the new tunnel eliminated the problem of radio silence between topside, maintenance, and tunnel teams. Workers now use a two-way radio and can access the tunnel without an escort, freeing up personnel for other tasks. The teams were no longer tethered to land lines, enabling them to complete multiple tasks simultaneously, which improved overall project deployment speed and productivity while reducing expenses. Tasks were dispatched from Ausgrid’s local project headquarters in Regent’s Park to field staff in seconds, not hours, eliminating the need for periodic land-line status calls or less frequent face-to-face surface returns. The technology also offers potential for further applications beyond the tunnel.

• Reduced the size of teams required to man tunnel exits and escort workers from three or four to typically one or two people, cutting costs by roughly half.
• Improved overall project deployment speed and productivity by enabling teams to complete multiple tasks simultaneously.
• Reduced waiting time for task dispatch from hours to seconds.
