The invention relates to the technical field of field
operation safety management, and discloses a field operation
personnel safety assessment method based on
network data acquisition and positioning, which comprises the following steps: dynamically selecting an anti-interference mode by a multimode
positioning technology to obtain positioning data, correcting track offset caused by
terrain reflection interference by combining a track prediction model, and calculating the safety of field operation personnel. A
signal enhancement node is utilized to construct an ad hoc network to optimize
data transmission, a safety evaluation model fused with a topographic slope trend is established for purified positioning data, parameters such as a speed threshold and a safety judgment threshold are dynamically adjusted by detecting surrounding obstacle distribution in real time, and when a safety state is abnormal, the positioning data are subjected to safety evaluation. And generating an optimal risk avoiding path based on the
terrain trafficability network, and synchronously starting three-channel emergency broadcast of the
cellular network, the
wireless talkback and the node
relay. According to the method, the complex
terrain positioning precision and the anti-interference capability are improved, the
data transmission reliability is enhanced, dynamic
risk assessment and early warning are realized, and the
emergency response efficiency and the rescue success rate are improved.
