he cloud of the push notification service, formulary information qr code image generation and resolution, map service orientation of emergency services and remote consultation diagnosis service. The implementation of the system to make ordinary users can enjoy more high-quality medical service. Aiming at wife in emergency location services positioning error. This paper proposes a fingerprint identification algorithm based on dynamic filtering optimization scheme. Simulation fingerprint database information in the simulation environment, and add gaussian noise simulation environment, compared with the original algorithm results show that the algorithm can improve the positioning accuracy to a certain extent. To apply this solution in positioning system can better meet the needs of the user.
