Problems solved by technology

[0002] There are many positioning devices such as positioning watches for the elderly or children, and anti-theft terminals for electric vehicles, which usually rely on GPS+GPRS modules. The advantages of GPS positioning are high precision and fast speed, but the disadvantages are also very obvious. The power consumption is large, and each time the position is calculated, it needs to consume a lot of power
Take the positioning watch as an example. Its power source is a rechargeable battery, and it needs to be recharged after 2-3 days of use. This is because the positioning cycle of the positioning watch is set to a long time, such as once every 5 minutes. If the device is 1 minute every time Even once every 30 seconds, the estimated power of the positioning watch cannot last for a day, and frequent charging is very troublesome, resulting in reduced user experience
Take the anti-theft terminal for electric vehicle anti-theft as an example. Although it can draw power from the battery of the electric vehicle, if the location is too frequent, the cruising range of the electric vehicle will be significantly reduced.

Embodiment 1

[0013] Embodiment 1, with reference to attached figure 1 , a positioning system, including several landmark tags 110 with a first radio frequency transceiver module 110, a device terminal 120 with a second radio frequency transceiver module 121 and a mobile communication module 122, a positioning module 142 and a third radio frequency transceiver module The location configuration device 140 and the server 130 of 141; the landmark tags 110 are distributed in the preset area and the combined signal ranges of all the landmark tags 110 can cover the preset area; when a certain landmark tag 110 is fixedly placed at the preset position, The location configuration device 140 sends the longitude and latitude information obtained by the positioning module 142 to the landmark tag 110 through the third radio frequency transceiver module 141 at the preset position; 110 heartbeat data including the longitude and latitude information of the location; when the device terminal 120 is in the p...

Embodiment 2

[0020] Embodiment 2, refer to attached figure 2 , a positioning system, including several landmark tags 210 with a first radio frequency transceiver module 211, a device terminal 220 with a second radio frequency transceiver module 221 and a first mobile communication module 222, a positioning module 241 and a second mobile communication module The location configuration device 240 and the server 230 of the module 242; the landmark tags 210 are distributed in the preset area and the signal ranges of all the landmark tags 210 are combined to cover the preset area; the landmark tags 210 are periodically externally transmitted through the first radio frequency transceiver module 211 Send the heartbeat data including the tag unique identification code; when a certain landmark tag 210 is fixedly placed at a preset position, the position configuration device 240 obtains the tag unique identification code of the landmark tag 210, and passes the first 2. The mobile communication modu...

Abstract

The invention relates to a positioning system. The positioning system includes a landmark label, a device terminal, and a server; the landmark labels are distributed in a preset area and the signal ranges of all the landmark labels are combined to cover the preset area, which periodically sending out heartbeat data including latitude and longitude information of the location where the landmark label is located; the device terminal receives the heartbeat data sent by the landmark label when the device terminal is in the preset area, saves the latitude and longitude information, records the corresponding receiving time, and uploads the latitude and longitude information, the receiving time, and the device terminal unique identification code to the server; and the server determines the approximate location of the device terminal at the receiving time according to the device terminal unique identification code, the latitude and longitude information, the receiving time, and the signal coverage of the landmark labels. The invention has the beneficial effects that: the device terminal in the system can save the GPS module; and compared with the device terminal equipped with the GPS module, the cost and power consumption of the device terminal are reduced under the same function of acquiring the location information.
