Abstract：Aiming at the problem that it may collide when construction workers are around the large track maintenance machinery，the anti-collision technology for construction workers was studied. A new positioning algorithm was proposed and the wireless communication ranging techniques were used to obtain objective data from the base station，then the theory of the intersection between the circle and hyperbolic was used to get position effectively. A security model of construction workers was built based on position data. This model can be used to determine the security status of construction workers effectively. The results indicate that，the positioning algorithm is high precision and the security model is simple and effective.
