Study On The Location And Tracking Of Indoor Moving Objects

In recent years,with the popularity of information technology,indoor mobile object positioning and tracking is the field of Internet of things research and application of hot and difficult.With the Internet + technology continues to mature and perfect,for the terminal control of the data needs also have unprecedented opportunities and challenges.With the ability to obtain information and wireless communications,as well as the ability to deal with information,the two fusion to promote the network of things.Such as large-scale warehouses,libraries,underground mines and other fields,the location of the object information within the system has become more and more functions of the basic data,but also marks the positioning and tracking technology in the sensor network plays a decisive role.So far,the indoor mobile object tracking technology does not have a mature feasibility program.This paper presents a positioning and tracking system for ZIGBEE indoor moving objects,which is a visual interface control program and TOA positioning technology.And its internal structure design,system working principle and its function,visual interface design ideas,moving object automatic driving design made a detailed description and description.And finally completed the realization of the various functions of the system,and the late system to improve the proposed changes.First,the position of the moving object is positioned by the ultrasonic positioning,and the position information of the moving body intelligent car is transmitted back to the gateway console through the wireless sensor network built by the ZigBee module.The gateway console then splits the data and transmits it to the visualization system.The visual interface can display the real-time position,the destination end position,the trajectory of the travel,the historical trajectory information of the moving object,and the user can Input the target end position of the moving body intelligent car,so as to realize the tracking and control of the moving body intelligent car.When the system is running normally,if there is an obstacle on the moving path of the moving object,the obstacle on the moving object will detect the obstacle and trigger the interrupt function to avoid the obstacle to ensure that the moving object can reach the target.The experimental results show that the control system has good response characteristics,can work for a long time,good stability,the initial realization of indoor moving objects positioning and tracking control.
