Magnetic Through-the-Earth Miner Transceiver for Emergency Communications

描述：即使我们进入了21世纪，矿难事故仍然经常发生，经常导致数十人丧生。如果有一个可靠的紧急通信系统，向搜救方和被困矿工提供救生信息，那么这些死亡事故中的许多都是可以避免的。为了解决这个问题，物理光学公司（POC）提议推进我们的新型磁通地矿机应急通信收发器（mathematice）系统的开发。该系统是用于双向通地（TTE）通信的收发器，通过在Edgar矿山（Idaho Springs， CO）和NIOSH实验矿山（Pittsburgh， PA）演示375英尺的TTE通信范围，该系统在第一阶段被证明是可行的。mathematicite集成了一种新型的零功率地雷发射机（ZPT）和通信协议，以在所有紧急情况下保持地雷与地面的通信。矿井发射机的创新使其能够在不需要外部电源或电池的情况下，通过超过2000英尺的覆盖层与地面接收器保持通信链路。数字降噪数据处理的应用使地面接收机能够在矿井环境噪声中检测到来自矿井发射机的唯一信号。这些优点也使所提出的收发器在商业上具有吸引力，因为它主要基于现有技术的集成。拟议的收发器的潜在市场不仅包括矿山安全，还包括建筑和能源行业，以及许多军事和安全应用。因此，POC提出的研究将通过提供可靠、紧凑、贯穿地球的通信系统，对参与地下作业的人员的安全产生重大而积极的影响。这直接支持了国家职业安全和健康研究所改善矿工安全和健康的使命。在第一阶段，POC通过一个缩小的原型，在375英尺的TTE通信范围内成功地证明了mathematicite系统在矿山作业中的可行性。第二阶段的目标是开发和演示一个全尺寸的原型系统，其范围可达2000英尺，可以完全安全地用于矿山，并且不需要额外的基础设施。除了原型开发之外，POC还将在矿山试验场进行广泛的测量，以准确表征矿山环境，包括环境噪声和干扰。POC将确保设计符合矿山安全和健康管理局的规定。该技术的成功开发将产生一种全新的应急通信系统，它将克服当前矿山通信技术的安全性、可靠性、功率和尺寸问题。

DESCRIPTION: Even as we move into the 21st century, mining accidents are still a regular occurrence, often resulting in the loss of dozens of lives. Many of these fatalities could have been averted had there been a reliable emergency communications system in place to provide life-saving information to search-and-rescue parties and to trapped miners. To address this problem, Physical Optics Corporation (POC) proposes to advance the development of our new Magnetic Through-The-Earth Miner Transceiver for Emergency Communications (MATHEMITE) System. This system is a transceiver for two-way through-the-earth (TTE) communications, which was proven feasible in Phase I by demonstrating a 375 ft TTE communication range at the Edgar Mine (Idaho Springs, CO) and at the NIOSH Experimental Mine (Pittsburgh, PA). MATHEMITE integrates a novel zero-power mine transmitter (ZPT) and communication protocol to maintain mine-to-surface communications in all emergency situations. Innovations in the mine transmitter enable maintaining a communication link with a surface receiver through more than 2000 ft of overburden with no external power or batteries required. Application of digital noise-reduction data processing allows the surface receiver to detect the unique signature arriving from the mine transmitter, amid the mine environmental noise. These advantages also make the proposed transceiver commercially attractive, since it is based largely on integration of existing technology. The potential markets for the proposed transceiver include not only mine safety but also construction and energy industries, in addition to numerous military and security applications. As a result, POC's proposed research will significantly and positively impact the safety of personnel involved in underground operations by providing a reliable, compact, through-the-earth communications system. This directly supports the mission of the National Institute for Occupational Safety and Health to improve safety and health of mining workers. In Phase I, POC successfully demonstrated the feasibility of the MATHEMITE system in mine operation with a scaled-down prototype over a 375 ft TTE communication range. The goal of Phase II is to develop and demonstrate a full-scale prototype system with a range of up to 2000 ft. that is completely safe for mine use and does not require additional infrastructure. Besides the prototype development, POC will conduct extensive measurements at mine test sites to accurately characterize the mine environment, including environmental noise and interference. POC will ensure the design meets Mine Safety and Health Administration regulations. Successful development of this technology will result in an entirely new emergency communications system that will overcome the safety, reliability, power, and size issues of current mine communications technology.
