摘要:

作战救灾等复杂场景下环境干扰大且难以获取外界信号、定位困难。惯性系统因其特性成为复杂场景下不可或缺的自主定位方式,但惯性器件存在累计误差,长航时状态下难以满足定位精度需求。超声波测距受环境影响小,成本较低,已成为辅助惯性器件进行行人定位的重要方式。目前惯性与超声波组合导航多为理论研究及仿真验证,少量可实现系统不便于后续研究实验的进行。针对上述问题,实现了一种基于Xsens公司Mti-G710型号微机电系统(micro-electromechanical systems, MEMS)和DAKOTA公司DJIN1002超声波模块的双足足绑式定位系统,并进行实测实验验证了系统的可行性。

Abstract:

In complex scenes such as combat and disaster relief, it is difficult to obtain external signals and locate. Due to its characteristics, inertial system has become an indispensable method of autonomous positioning in complex scenes, but there exist accumulated errors for inertial devices, which cannot meet the requirements of long-range positioning accuracy. Ultrasonic ranging is less influenced by the environment and has a low cost, which has become an important way to assist inertial devices in pedestrian positioning. At present, inertial and ultrasonic combined navigation are mostly theoretical research and simulation verification, and a small number of realizable systems are not convenient for subsequent research and experiments. In view of the above problems, a double full binding positioning system is realized based on Mti-G710 micro-electromechanical systems (MEMS) of Xsens company and DJIN1002 ultrasonic module of DAKOTA company, and field tests are conducted to verify the feasibility of the system.

Key words: double feet munted, micro-electromechanical system (MEMS), ultrasonic module, pedestrian positioning, system implementation
