Embodiment 1

[0026] An embodiment of the present invention provides an information collection method, such as figure 1 As shown, the method includes:

[0027] Step S101. Obtain the first GPS information of the device collected by the GPS collection component of the device.

[0028] It should be noted that the execution subject of the information collection method in this embodiment is an information collection device, and the information collection device is a device that can track the GPS information of an object in real time, such as a vehicle-mounted GPS device, with GPS positioning Functional smart phones, smart computers with GPS positioning functions, etc. The device includes a processor, a GPS acquisition module, and a communication module; wherein, the GPS acquisition module collects the GPS information of the device, and sends the collected GPS information to the processor of the device through the serial port communication module, and the processor receives the GPS The informat...

Embodiment 2

[0043] An embodiment of the present invention provides an information collection method, the method comprising:

[0044] Step S201. Obtain the first GPS information of the device collected by the GPS acquisition component of the device.

[0045] The content of this step is the same as the content of step S101 in the first embodiment, and will not be repeated in this embodiment.

[0046] Step S202. Determine a first moving speed of the device according to the first GPS information.

[0047] Determine the first displacement information according to the difference between the second GPS information and the first GPS information, the second GPS information is the GPS information collected before collecting the first GPS information; determine the time difference, and the time difference is for collecting the first GPS information The difference between the time stamp corresponding to the first GPS information and the time stamp corresponding to the collection of the second GPS in...

Embodiment 3

[0068] An embodiment of the present invention provides an information collection method, the information collection method includes:

[0069] The vehicle-mounted GPS device stores the logical relationship between the moving speed range of the vehicle-mounted GPS device and the reporting frequency of the vehicle-mounted GPS device, and dynamically adjusts the GPS position information reporting frequency according to the reporting position frequency corresponding to the moving speed range of the vehicle-mounted GPS device.

[0070] After obtaining the moving speed of the vehicle-mounted GPS device, find the reporting frequency corresponding to the current moving speed of the vehicle-mounted GPS device, and compare the speed of the new reporting frequency with the old reporting frequency. If the former is faster, it means that the moving speed of the device is accelerating. At this time, immediately upload the GPS position information once so as to track the movement of the vehicl...

Abstract

The embodiment of the present invention discloses an information collection method. The method includes: acquiring the first GPS information of the device collected by the GPS acquisition unit of the device; determining the first GPS information of the device according to the first GPS information A moving speed; determining a first moving speed interval corresponding to the first moving speed, determining a corresponding first reporting frequency according to the first moving speed interval; reporting the first GPS information according to the first reporting frequency to a server on the Internet. The embodiment of the invention also discloses an information collection device.

Description

technical field [0001] The invention relates to the field of communication, in particular to an information collection method and device. Background technique [0002] With the development of communication technology, vehicle-mounted global positioning system (GPS, Global Positioning System) has been widely used in people's daily life. The current vehicle-mounted GPS device only has a single-chip microcomputer (MCU, Microcontroller Unit), GPS module and communication module inside. By continuously collecting GPS information, the location data is uploaded to the server in the network at fixed time intervals. Most of the existing GPS trackers are vehicle-mounted GPS devices that collect and report location information according to a fixed reporting frequency; or the frequency of vehicle-mounted GPS devices reporting information changes in real time as the vehicle-mounted GPS device's moving speed changes. When using a fixed reporting frequency to report information, when the ...
