Embodiment 1
[0050] Personnel positioning system based on mobile Internet, such as figure 1 As shown, it includes a radio frequency identification electronic label unit 1, a mobile terminal 2, and a GIS server 3;
[0051] The radio frequency identification electronic tag unit 1 includes more than one radio frequency identification electronic tag 11, and the radio frequency identification electronic tag 11 periodically transmits a wireless broadcast signal with a radio frequency identification code;
[0052] The mobile terminal 2 includes a radio frequency identification reader-writer 21 and a signal transceiver 22;
[0053] The radio frequency identification reader 21 is used to receive the wireless broadcast signal transmitted by the radio frequency identification electronic tag 11, and the signal transceiver 22 and the GIS server unit 3 perform data transmission through wireless wifi or mobile communication technology 2G\3G\4G network. The present invention is suitable for occasions whe...
Embodiment 2
[0060] The personnel positioning method based on the mobile Internet includes the above-mentioned personnel positioning system based on the mobile Internet. After receiving the data sent by the mobile terminal 2, the GIS server 3 performs positioning by the following methods:
[0061] ①. Determine the position of the radio frequency identification electronic tag 11 in the selected area, and assign a fixed IDxIDx, x=1, ... n to each radio frequency identification electronic tag 11;
[0062] 2. Sorting: The signal of the radio frequency identification electronic tag 11IDx received by the mobile terminal 2 within the selected area is TagiTagi, i=1, ... n, the actual path is determined according to the actual route of the mobile terminal 2, and the radio frequency is determined according to the actual path. Identify the electronic tags 11IDx for sorting; judge whether the radio frequency identification electronic tag 11 that has received the signal Tagi conforms to the actual path,...
Embodiment 3
[0087] The method for indoor positioning of personnel based on the mobile Internet. This implementation uses indoor room positioning as an example. There are 3 rooms, distributed as room A, room B, room C, and one corridor. like image 3 Shown:
[0088] It is required to accurately locate a specific room. It can be seen from the figure that from room A to room B, one must first exit the door of room A and pass through the corridor TagD before entering room B. To go to room C, one must pass through the corridor tagE. Assuming that the current location of the person is in room A, affected by the human body, the signal strength value of TagB obtained by the mobile phone is sometimes higher than the signal strength value of TagA received by the mobile phone. No matter how strong the location RSSI value is, the system will not initiate a new positioning, the location point will not be updated, and the mobile phone is still positioned in room A. Only after leaving the room A, comp...
