Problems solved by technology

[0005] Among the above three positioning methods, Beidou has the highest positioning accuracy and the most accurate results, but is limited by the satellite coverage and cannot be used indoors or in remote areas. The cellular positioning system has the worst positioning accuracy and large deviations in results, but The coverage is wide, and it can still be used normally indoors. The positioning accuracy of the dead reckoning function is between Beidou positioning and cellular positioning, but the dead reckoning function has accumulated errors, and the positioning accuracy cannot be guaranteed after a long time of use. Therefore, simply using Positioning with one positioning method will have a small positioning range and poor positioning accuracy
[0006] In addition, the traditional positioning and tracking terminal combines the positioning module and the communication module, which can upload the position information of the terminal carrier to the monitoring terminal at a certain transmission rate in real time, and the monitoring terminal can realize positioning and tracking by processing the position information, regardless of the position of the carrier Whether the information changes, the monitoring terminal will continuously receive the positioning information from the positioning module, which consumes a lot of power and the battery life of the device is poor

Embodiment 1

[0033] Such as figure 1 As shown, the transmission rate adaptive intelligent power-saving 4G positioning and tracking terminal of the present invention includes:

[0034]The Beidou positioning module is used to measure the position and speed information of the carrier, and output the navigation message to the core controller;

[0035] Dead reckoning sensor, when the positioning of the Beidou positioning module is not available, start the dead reckoning sensor, use the last available positioning result of the Beidou positioning module to calculate, obtain the position and speed of the carrier, and transmit the position and speed information of the carrier to the core controller ;

[0036] The cellular positioning module determines an acceptable error accumulation time according to the measurement accuracy of the dead reckoning sensor, and after the dead reckoning sensor continues to work for the error accumulation time, the cellular positioning module is turned on for position...

Embodiment 2

[0045] Such as figure 2 As shown, the transmission rate adaptive intelligent power-saving 4G positioning and tracking method of the present invention first obtains the carrier position and speed information through the positioning fusion method, and then uses the transmission rate adaptive intelligent power-saving method to transmit the carrier position and speed information to the monitoring system. terminal,

[0046] The location fusion method is:

[0047] When starting, the Beidou positioning module runs first, and reads the navigation message output by the Beidou positioning module through the core controller, and the core controller reads the navigation message output by the Beidou positioning module; according to the read PDOP (Position Dilution of Precision, position precision factor ) to determine whether the positioning data is available, if it is detected that the PDOP value is unavailable, turn on the dead reckoning sensor, and use the position and speed informati...

Abstract

The invention relates to the technical field of 4G locating, in particular to a transmissibility-adaptive intelligent electricity-saving 4G locating and tracking device. A Beidou locating module, a dead reckoning sensor and a cellular location module are connected with a kernel controller, and the kernel controller is connected with a monitoring terminal through a 4G communication module. The invention further relates to a transmissibility-adaptive intelligent electricity-saving 4G locating and tracking method. The method includes the steps that carrier position information is obtained through a location fusion method, and then the carrier position information is transmitted to the monitoring terminal in a transmissibility-adaptive intelligent electricity-saving method. According to the device and method, three traditional locating methods, namely Beidou locating, dead reckoning and cellular location are integrated. The kernel controller accurately judges the locating method needing to be used according to current environment, location stability is high, and reliability is good. Meanwhile, the kernel controller changes the time interval for uploading and updating carrier positions and speed information according to real-time moving speed of carriers, transmissibility self-adaptation is achieved, and endurance is improved.

Description

technical field [0001] The invention relates to the technical field of 4G positioning, in particular to a transmission rate adaptive intelligent power-saving 4G positioning and tracking device and method. Background technique [0002] The Beidou satellite navigation system is a global satellite navigation system independently developed and independently operated by China, abbreviated as BDS, a global satellite navigation system compatible with the US GPS, Russia's GLONASS, and the EU's Galileo system The world's four major satellite navigation systems. The Beidou satellite navigation system provides continuous navigation, positioning and timing services, and cooperates with the receiver to obtain the running speed and position of the receiver carrier. [0003] Dead reckoning is a method of calculating the position at the next time by measuring the distance and azimuth of the movement under the condition of knowing the current position. The dead reckoning algorithm was orig...
