Problems solved by technology

However, the Bluetooth detector continues to detect the positioning information sent by the Bluetooth tag and transmits the data to the background system through communication technologies such as WiFi, 3G, 4G or network cables. Therefore, the Bluetooth detector needs to be connected to an external power supply or a POE network cable. The cost of the Bluetooth detector is high and deployment is difficult. The cost is extremely high, which greatly limits the application of this method

Embodiment Construction

[0030] Embodiments of the present invention are described in detail below.

[0031] see figure 1 , the present invention provides a base station switching method in low-power indoor and outdoor positioning technology, comprising the following steps:

[0032] S1. Deploy a low-power positioning node in a required indoor environment, where the low-power positioning node includes a Bluetooth positioning beacon;

[0033] S2. After receiving the positioning information, the receiving end uses LPWAN technology to establish a connection with the base station, and transmits the positioning information to the background monitoring system through the base station for position calculation. The receiving end automatically selects and switches to the most suitable position as the position of the target changes. base station for data transmission;

[0034] S3. The satellite navigation system is used for positioning outdoors, and the latitude and longitude results output by the satellite na...

Abstract

The invention discloses a base station switching method in a low-power indoor-outdoor positioning technology. The method comprises the following steps: deploying a low-power positioning node in an indoor environment, implementing low-power transmission of positioning information to a background monitoring system by a LPWAN (Low-Power Wide-Area Network) technology, finishing indoor positioning on the background, meanwhile performing outdoor positioning by a satellite navigation system, and returning longitude and latitude results output by the satellite navigation system to the background through the LPWAN to realize indoor-outdoor omni-directional positioning; and deploying a plurality of base stations, making a preset table for positioning nodes under the coverage of the base stations, recording base station information for communication connections to be selected by receiving ends at locations where the positioning nodes are positioned in the table, selecting whether to switch between base stations according to the power of a positioning tag radio-frequency signal or internally switching to an appropriate modulation way, and performing modulated transmission of signal data in order that positioning is more accurate.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to a base station switching method in low power consumption indoor and outdoor positioning technology. Background technique [0002] With the continuous development of the Internet of Things technology, the society's demand and expectation for the Internet of Everything continues to rise, especially in the field of indoor positioning, and the demand for positioning scenarios is increasing, which also promotes the development of positioning methods. Many solutions for obtaining positioning information have been proposed, such as GNSS, WiFi positioning method, Bluetooth positioning method, RFID, UWB and other technologies. [0003] At present, the indoor positioning market has broad prospects. iBeacon is a technical solution launched by Apple, which opens a new entry for indoor positioning applications. Many indoor positioning solutions based on this technology have emerged as th...
