Abstract

The invention discloses a scorpion micro-vibration positioning mechanism-based activity track positioning method and system, and the method comprises the following steps: building a first-level neuronmodel which simulates scorpion sensory neurons, and converting a vibration signal received by a sensor into a pulse signal; establishing a scorpion synapse-imitating plastic synapse model, and obtaining synapse conductance according to the pulse signal; and establishing a secondary neuron model, and estimating the direction of the vibration source according to the synaptic conductance emission secondary neuron pulse. The scorpions are simulated to accurately position prey, and the positioning technology with the biological function is adopted. Vibration signals reaching different receivers are jointly coded by utilizing a pulse neural network, and information transmission between neurons is realized by establishing synaptic connection between the neurons, so that the azimuth information of vibration source signals is obtained.

Description

Technical field [0001] The invention relates to the technical field of bionic perception and information processing, in particular to an activity track positioning method and system based on a scorpion micro-vibration positioning mechanism. Background technique [0002] Positioning is one of the core technologies for location services, Internet of Everything, artificial intelligence and future superintelligence (robot + human) applications. At present, the most widely used location service system is Global Navigation Satellites Systems (GNSS), which has a dynamic positioning accuracy up to sub-meter level in an open outdoor environment. However, satellite signals will be affected by unfavorable factors such as blocking and multipath propagation, making the global satellite navigation system unable to achieve a good positioning effect in the "urban canyon" with high-rise buildings or indoor buildings, which limits the system's indoor environment Use and development in People’s d...
