安全、健康和环境

炼化企业大检修时期，现场承包商单位人员数量多、流动性大、安全管理难度大，传统技术多采用定位工卡加辅助信标的定位方式，难以适应这种人员大量集中和动态波动的问题。基于此，在企业现有北斗人员定位系统及附属设施的基础上，通过定位APP持续保活、多信号数据动态寻优及粒子滤波结合路网匹配的优化方法，扩展开发了一套在装置检修期间利用作业人员个人手机进行定位的星地融合定位方式，并在炼化企业的实际应用中打通门禁、闸机等关联系统，构建了一套创新的人员位置管控模式。结果表明，该系统实现了超过6 h的手机持续定位以及承包商人员最多2 660人的实时在线定位，同时在装置区、罐区等生产区域的位置轨迹更为准确、合理，而且无需投入其他硬件设施，形成了一种低成本且可动态适应大检修人员波动变化的新定位方式。

During the major maintenance period of petrochemical enterprises, the on-site contractor units have a large number of personnel, high mobility, and great difficulty in safety management. Traditional technologies mostly adopt the positioning method of work pass location combined with auxiliary beacons, which is difficult to adapt to the issues of large personnel concentration and dynamic fluctuations. On the basis of the existing Beidou personnel positioning system and ancillary facilities of the enterprise, an optimized method was developed. This method combines continuous keep-alive via positioning apps, dynamic optimization of multi-signal data, and particle filtering combined with road network matching. A satellite-ground integrated positioning method that uses the personal mobile phones of operation personnel for positioning during the maintenance period of the equipment has been exploited. In the actual application of petrochemical enterprises, related systems such as access control and turnstiles have been connected, and an innovative personnel location control mode has been constructed. The results showed that the system has achieved continuous positioning of mobile phones exceeding 6 hours and real-time online positioning of up to 2 660 contractor personnel. Meanwhile, the position trajectories in production areas such as the process unit area and tank area are more accurate and reasonable. Moreover, no other hardware facilities need to be invested in, forming a new positioning method that is low-cost and can dynamically adapt to the personnel fluctuation changes during major maintenance operations.
