Pulse positioning model based on bionic sand scorpion positioning function

Abstract

A pulse positioning model based on a bionic sand scorpion positioning function belongs to the information processing technology field. The invention aims at carrying out positioning under a non-vision condition. The pulse positioning model based on the bionic sand scorpion positioning function uses a vibration signal of matrix transfer to carry out positioning on a target. The model has the following steps of (1) defining a sensor position; (2) carrying out neuron modeling; (3) setting interaction of 8 neuron models; and (4) using excitability of a neuron to position. In the invention, a function of simulating a sand scorpion sense of touch to position a prey is possessed, a vibration sensor is used to substitute a mechanical sense receiver BBCS of a sand scorpion to receive the vibration signal, and combination is performed according to an arrangement mode of the BCSS, and then through interaction of internal portions of a nerve network, the neuron evaluates the vibration signal so as to carry out positioning. Because of vibration positioning of the bionic sand scorpion, information contents of the processed signal are reduced and operand is decreased so that positioning time is shortened.

Description

technical field [0001] The invention belongs to the technical field of information processing. Background technique [0002] In nature, many species communicate or locate prey through "sound waves" transmitted on the ground. For example, eight-legged arthropods such as sand scorpions and spiders can use the sensory organs at the end of their legs to find prey. The article "Prey Detection by the Sand" shows that sand scorpions use the vibrations transmitted by the sand to locate prey or communicate with their own species. The sensory organ of the sand scorpion is the basitarsal compound slit sensilla BCSS (basitarsal compound slit sensilla), which is used to detect the low-speed and low-frequency surface waves propagated by the matrix. When hunting, the sand scorpion will advance or turn with the movement of the prey, and find the moving prey by detecting low-speed and low-frequency vibration signals. It can detect vibration signals as small as 0.1nm and accurately find the ...

Problems solved by technology

However, the positioning distance of the sand scorpion is limited. The article points out that the sand scorpion can locate the direction and distance of the prey within 10cm. When the distance reaches 30cm, it can only perceive the direction.
