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...
