Abstract

Researchers at the National Institute for Occupational Safety and Health (NIOSH) are developing intelligent software for use with electromagnetic proximity detection systems. The technology accurately locates workers around mining machines in real time. With the accurate locations of the workers around the equipment being known, their safety status can be evaluated. If a worker is located dangerously close to a machine, the machine can be partially or completely disabled to protect the worker from striking, pinning and entanglement hazards according to pre-defined logic. The technology is particularly applicable to mobile underground mining machines which offer difficult safety challenges in that operators generally work in close proximity to these machines in very restricted spaces. With use of the intelligent proximity detection system, nuisance alarms and failures to alarm are also expected to be sharply reduced. An effective proximity warning and action zone scheme is necessary for safe implementation and will improve the acceptance of a magnetic proximity detection system by underground workers.

确定磁接近探测系统的接近警告和动作区域
国家职业安全与健康研究所(NIOSH)的研究人员正在开发用于电磁接近检测系统的智能软件。该技术可以实时准确地定位矿机周围的工人。有了设备周围工作人员的准确位置,就可以评估他们的安全状况。如果工人危险地靠近机器,根据预先定义的逻辑,机器可以部分或完全禁用,以保护工人免受撞击,钉住和纠缠的危险。该技术特别适用于移动地下采矿机,因为操作人员通常在非常有限的空间内靠近这些机器工作,这对安全提出了困难的挑战。由于采用了智能近距离探测系统,预计滋扰警报和未报警的情况也会大幅减少。有效的接近警报和行动区方案是安全实施所必需的,并将提高地下工人对磁性接近探测系统的接受程度。
