Embodiment Construction

[0015] 1. System architecture

[0016] The motion parameter collection system of moving objects is a system that collects multiple motion parameters in real time. The system uses the most rapidly developing and powerful Android operating system as a parameter collection development platform. The direction sensor, acceleration sensor, gyroscope and GPS are used to obtain the heading angle, spatial three-axis acceleration value, spatial three-axis angular velocity value, longitude, latitude, altitude and other position information during the movement of the object. And through the mobile phone mobile communication 3G / 4G network, the above parameters are transmitted to the server in real time, and the latitude and longitude position information at the specified time can be saved. Since the data collected by the sensor in the smart phone will have certain errors, the median filter algorithm is introduced for error correction processing. After correction, the accuracy of heading a...

Abstract

The invention relates to an Android phone based remote acquisition method for position and motion parameters of moving objects. According to the method, a course angle, a space triaxial acceleration value, a space triaxial angular speed value and longitude and latitude position information of an object in a moving process are collected and acquired by an Android operating system of a mobile phone through a direction sensor, an acceleration sensor, a gyroscope and a GPS (global positioning system) in the mobile phone, data are subjected to error correction processing with a median filter algorithm, then parameters are transmitted to a server through 3G/4G network in real time, the longitude and latitude position information of a designated moment is stored by the server, each time the operating range of the GPS exceeds 200 m, position information is collected once, the server monitors motion data and position information of multiple moving objects simultaneously, and a server monitoring interface is connected with a backend database to store or retrieve position data of a certain moment for regional positioning on a map. The method can be implemented only by one Android smartphone, a special instrument and a wireless communication module are not required, and operating and maintaining costs are lower.

Description

technical field [0001] The invention relates to the field of remote monitoring, in particular to a method for remotely collecting the position and motion parameters of a mobile object based on an Android phone. Background technique [0002] How to monitor the longitude and latitude position information and motion parameters of moving objects such as cars and ships in real time in different places is a problem worth studying. It has important application value in security monitoring, anti-theft design and other fields. [0003] At present, the remote monitoring of the position and motion parameters of moving objects generally uses special sensors, instruments, and wireless transmission equipment, which generally has the problems of complex systems and high operation and maintenance costs. Contents of the invention [0004] The present invention aims at the problems existing in the remote monitoring of the position and motion parameters of the mobile object, and proposes a ...
