Detailed ways

The above described objects, features and advantages of the present application will become more apparent and understood.

A LoRa network consists of a terminal node, a base station node, and a server. The terminal has a LoRa network connection capability and is connected to the LoRa network. The terminal may include different electronic devices according to different application scenarios deployed by the LoRa network. For example, when the LoRa network is applied to urban management, the terminal may include a smart meter; and the LoRa network is used in a digital home. The terminal can include various smart home appliances and the like.

The base station, also referred to as a gateway or concentrator in the LoRa network, has a wireless connection aggregation function, including the terminal providing access to the LoRa network, forwarding data from the server or the terminal, and realizing data between the terminal and the server. Interaction. Of course, the base station can also perform data interaction by transmitting wireless frames with other base stations within the signal coverage of the base station.

The server may include a server or a server cluster for performing service processing according to data acquired from the base station or the terminal, and controlling the working mode and working state of the base station or the terminal.

At present, an important reason for the low positioning accuracy of the LoRa network is the use of a low frequency and low bandwidth wireless frequency band. One of the core concepts of the embodiments of the present application is that the LoRa positioning scheme no longer uses the existing low-frequency narrow-band LoRa module (the operating frequency includes but not limited to the 470M-510MHz frequency band) for ranging, but uses the high-frequency LoRa. The module (operating frequency includes but not limited to the 2.4 GHz band) achieves ranging. Although the low-frequency narrow-band LoRa module has the characteristics of low power consumption, long transmission distance, and high sensitivity, the ranging accuracy is low. The high-frequency LoRa module has higher power consumption, shorter transmission distance, higher sensitivity, and higher ranging accuracy. In addition, the maximum transmit power of the 470M-510MHz band is 17dbm, and the maximum transmit power of the 2.4G band can reach more than 20dbm, and the transmission power is higher.

Referring to FIG. 1, a flow chart of steps of Embodiment 1 of a positioning method of a communication network according to the present application is shown. The communication network includes: a server, a base station having a first high frequency ranging module, and a second high frequency. The terminal of the ranging module may specifically include the following steps:

Specifically, the first base station is a base station capable of communicating with the terminal, and the terminal is within the coverage of each first base station.

In some specific areas (eg, campus), the location of the base station and the terminal are fixed, and the server can directly determine which base stations are covered by the terminal.

In addition, the LoRa network itself has mechanisms and protocols that enable the server to know which base stations are covered by the terminal.

Step 102: The first base station sends a ranging request radio frame to the second high-frequency ranging module of the terminal by using the first high-frequency ranging module of the terminal;

The server may notify each of the first base stations to transmit a ranging request radio frame.

Each of the first base stations sequentially transmits a ranging request radio frame to the second high frequency ranging module of the terminal through its first high frequency ranging module according to a certain timing.

The operating frequency of the high frequency ranging module includes, but is not limited to, the 2.4 GHz band.

Step 103: The terminal sends, by using the second high-frequency ranging module of the first base station, a ranging response radio frame for the ranging request radio frame to the first high-frequency ranging module of the first base station;

After receiving the ranging request radio frame, the terminal sends a pin ranging response radio frame through the first high frequency ranging module of each first base station through its second high frequency ranging module.

Step 104: The first base station calculates the distance information of the first base station and the terminal by using the ranging high-frequency ranging module by using the first high-frequency ranging module, and sends the distance information to the server. ;

After receiving the ranging response radio frame, the first base station calculates the distance between the first base station and the terminal through its first high frequency ranging module.

The high frequency ranging module has an algorithm for calculating distance information. Specifically, the high-frequency ranging module sends the ranging time t1 of the radio frame and the pick-up time t2 of the radio frame received by the ranging according to the ranging request, and then requests the radio frame and the ranging to respond to the duration of the radio frame according to the ranging, By fixing the processing time of the chip, it is possible to calculate the flight time of the radio wave between the two points of the distance measurement, thereby calculating the distance.

Each first base station transmits the calculated distance information to the server.

Step 105: The server calculates distances of the terminals by using distance information between each first base station and the terminal.

The radio frame is requested; finally, the second base station sends the positioning request radio frame to the terminal to inform the terminal that the positioning is about to be performed.

After receiving the positioning request radio frame, the terminal may obtain the first identification information from the positioning request radio frame analysis. Further, the transmit power, the frequency parameter, the bandwidth parameter, the modulation parameter, and the like of the ranging request radio frame in the subsequent process may also be analyzed from the positioning request radio frame.

In the embodiment of the present application, it is determined by the identifier whether the base station and the terminal are allowed to perform ranging, and the base station that allows the ranging is guaranteed to be a predetermined base station by the server.
