It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a preferred embodiment of a BLE-LoRa-GPS-based region positioning method. The method comprises the following steps:
step S1, dividing a positioning area into a first type area and a second type area 200 which are mutually independent;
step S2, a LoRa wireless transmission module is arranged in the second type area 200, and the signal of the LoRa wireless transmission module covers the whole second type area 200;
step S3, a special area 300 is divided into the second type area 200, an ibeacon beacon 301 is disposed in the special area 300, and the signal of the ibeacon beacon 301 covers the whole special area 300;
s4, installing a first positioning module and a second positioning module on the positioning terminal;
and S5, judging the area where the positioning terminal is located according to the receiving condition of the second positioning module on the signals of the LoRa wireless transmission module and the ibeacon beacon.
The steps S2 and S3 are performed after the step S1, the sequence of the steps S2 and S3 may be interchanged, and the step S4 may be performed synchronously with the step S1 without special requirements.
In this embodiment, the positioning area is a complex and diverse area, and we divide the positioning area into a first type area and a second type area 200 according to the topographical features of the positioning area, and divide a special area 300 in the second type area. The first type of area is an outdoor open area, and GPS satellite signals can be effectively transmitted in the outdoor open area, so that GPS can be adopted for positioning. The second type of area 200 is a large indoor building, such as a park or a base, which may be an industrial park, a large park, etc., a fruit and vegetable generation base, etc. The special area 300 is a small indoor building, such as a building or a room. In the second type area 200 and the special area 300, the GPS satellite signals are blocked to different degrees, so that the GPS positioning is not adopted.
In this embodiment, the first positioning module is a GPS positioning module. It has been pointed out above that the first type of area belongs to the open outdoor area and that GPS satellite signals can be efficiently transmitted. Thus, installing the GPS positioning module on the positioning terminal can realize positioning in the first type area. While GPS positioning is a relatively mature technology, and is not described in detail herein.
In this embodiment, the LoRa wireless transmission module includes a LoRa gateway 201 and a LoRa repeater, where the LoRa repeater and the LoRa gateway 201 are wirelessly connected to form a Mesh network. The LoRa gateway 201 is used to cover a majority of the area of the second type 200, and then the LoRa repeater is used to cover the dead zone of the LoRa gateway 201, so that the entire LoRa wireless transmission module covers the entire second area. Referring to fig. 1, in the second type area 200 of the positioning area in the present embodiment, one of the LoRa gateways 201 and three of the LoRa repeaters, which are a first LoRa repeater 202, a second LoRa repeater 203 and a third LoRa repeater 204, respectively, are arranged.
In this embodiment, an ibeacon beacon 301 is deployed in the special area 300, and the signal of the ibeacon beacon 301 covers the whole special area 300. Specifically, in the special area 300 of the positioning area in this embodiment, one ibeacon beacon 301 is disposed.
In this embodiment, the second positioning module includes a LoRa transceiver for communicating with the LoRa gateway 201 and the LoRa repeater.
In this embodiment, the second positioning module further includes a BLE transceiver for communicating with the ibeacon beacon 301.
In the step S5, the "determining, according to the receiving condition of the signals of the LoRa wireless transmission module and the ibeacon beacon by the second positioning module, the area where the positioning terminal is located" includes: when the BLE transceiver of the positioning terminal receives a broadcast signal of one ibeacon beacon 301 and uploads the received broadcast signal of the ibeacon beacon 301 to a server, the server determines that the positioning terminal is within an area covered by the corresponding ibeacon beacon 301. Specifically, when the positioning terminal enters the special area 300, since the broadcast signal of the ibeacon beacon 301 covers the whole special area 300, the BLE transceiver on the positioning terminal will receive the broadcast signal of the ibeacon beacon 301, and then the positioning terminal uploads the received broadcast signal of the ibeacon beacon 301 to a server, and the server can determine that the positioning terminal is currently located in the special area 300 covered by the ibeacon beacon 301.
In the step S5, the "determining, according to the receiving condition of the signals of the LoRa wireless transmission module and the ibeacon beacon by the second positioning module, the area where the positioning terminal is located" includes: when the BLE transceiver of the positioning terminal does not receive the broadcast signal of the ibeacon beacon 301, and the LoRa transceiver directly receives the signal of the LoRa gateway 201 and uploads the received signal of the LoRa gateway 201 to a server, the server determines that the positioning terminal is within the area covered by the corresponding LoRa gateway 201. Specifically, when the positioning terminal enters the second type of area 200 covered by the LoRa gateway 201, the LoRa transceiver of the positioning terminal may receive the signal of the LoRa gateway 201, and then the positioning terminal uploads the received signal of the LoRa gateway 201 to a server, and the server may determine that the positioning terminal is currently located in the second type of area 200 covered by the LoRa gateway 201 and is outside the areas covered by the first LoRa repeater 202, the second LoRa repeater 203, the third LoRa repeater 204 and the ibeacon beacon 301.
In the step S5, the "determining, according to the receiving condition of the signals of the LoRa wireless transmission module and the ibeacon beacon by the second positioning module, the area where the positioning terminal is located" includes: when the BLE transceiver of the positioning terminal does not receive the broadcast signal of the ibeacon beacon 301 and the LoRa transceiver receives the signal of the LoRa repeater and uploads the received signal of the LoRa repeater to a server, the server determines that the positioning terminal is within an area covered by the corresponding LoRa repeater. Specifically, when the positioning terminal enters the second type area 200 covered by the first LoRa repeater 202, the LoRa transceiver of the positioning terminal may receive the signal of the first LoRa repeater 202, and then the positioning terminal uploads the received signal of the first LoRa repeater 202 to a server, and the server may determine that the positioning terminal is currently located in the second type area 200 covered by the first LoRa repeater 202; when the positioning terminal enters the second type of area 200 covered by the second LoRa repeater 203, the LoRa transceiver of the positioning terminal may receive the signal of the second LoRa repeater 203, and then the positioning terminal uploads the received signal of the second LoRa repeater 203 to a server, and the server may determine that the positioning terminal is currently located in the second type of area 200 covered by the second LoRa repeater 203; when the positioning terminal enters the second type of area 200 covered by the third LoRa repeater 204, the LoRa transceiver of the positioning terminal may receive the signal of the third LoRa repeater 204, and then the positioning terminal may upload the received signal of the third LoRa repeater 204 to a server, which may determine that the positioning terminal is currently located in a portion of the second type of area 200 covered by the third LoRa repeater 204 that is outside the area covered by the ibeacon beacon 301.
In the step S5, the "determining, according to the receiving condition of the signals of the LoRa wireless transmission module and the ibeacon beacon by the second positioning module, the area where the positioning terminal is located" includes: the server determines that the positioning terminal is within the first type of region when the BLE transceiver of the positioning terminal does not receive the broadcast signal of the ibeacon beacon and when the LoRa transceiver of the positioning terminal does not receive the signals of the LoRa gateway and the LoRa repeater. Specifically, when the BLE transceiver on the positioning terminal does not receive the broadcast signal of the ibeacon beacon 301, and the LoRa transceiver also does not receive the signals of the LoRa gateway 201, the first LoRa repeater 201, the second LoRa repeater 203, and the third LoRa repeater 204, it may be determined that the positioning terminal is in the first type area. Then a more accurate positioning can be subsequently performed by the first positioning module, i.e. the GPS positioning module.
