Embodiment 1

[0063] A positioning tracking system based on Lora and NB-IoT, such as figure 1 As shown, it includes Lora host module, Lora slave module, NB-IoT module, main control module, power supply module, GPS positioning module, server, and client; among them,

[0064] The Lora host module (WH-L101 module) is used to configure the Lora point-to-point communication mode, data anti-theft protocol, receive and parse the data packets sent by the Lora slave module, and transmit the positioning information serial port to the server;

[0065] The server (host of the CentOS7 system) is connected to the Lora host module for storing all positioning information and transmitting the positioning information to the client;

[0066] The Lora slave module (WH-L101 module) is connected to the main control module, used to receive the data sent by the serial port of the main control module, and forward the data to the Lora main module through the license-free frequency band;

[0067] The NB-IoT module (...

Embodiment 2

[0075] A positioning tracking method based on Lora and NB-IoT, such as Figure 1-2 shown, including the following steps:

[0076] Step 1: Connect the serial port of the main control module to the Lora slave module, NB-IoT module, GPS positioning module, and power module, and the serial port of the Lora host module to the server. Set the working mode of the Lora host module to point-to-point communication, and fix the main control module on the device that needs to be positioned and tracked.

[0077] Step 2: The main control module receives the position information of the GPS positioning module in real time, compares it with the set device position, and calculates the positioning offset distance. When the offset distance is within 50 meters, the main control module transmits the positioning information through the Lora slave module to the The server connected to the Lora host module. When the offset distance is greater than 50 meters, receive 20 pieces of positioning informat...

Abstract

The invention discloses a Lora and NB-LoT-based positioning and tracking system and method, comprising a Lora host module for configuring a Lora point-to-point communication mode, a data anti-theft protocol, receiving and parsing data packets sent by a Lora slave module, and positioning the Lora The serial port of information is transmitted to the server; the server is connected to the Lora host module, used to store all positioning information, and transmit the positioning information to the client; the Lora slave module is connected to the main control module and used to receive the main control module The data sent by the serial port is forwarded to the Lora host module through the unlicensed frequency band; the NB‑IoT module is connected to the host control module and is in a dormant state when the device is not stolen to save energy and traffic. When working normally, it replaces the Lora module for positioning and tracking. When the device is stolen, the base station positioning is turned on to achieve long-term distance tracking; the GPS positioning module is connected to the main control module. The invention has high positioning accuracy, low positioning cost, long tracking distance, independent power supply, and no interference in positioning information transmission.

Description

technical field [0001] The present invention relates to a positioning tracking system and method, in particular to a positioning tracking system and method based on Lora and NB-IoT. Background technique [0002] With the continuous increase of domestic labor costs, more and more unattended automation equipment has been launched, such as vending machines, automatic car washing machines, etc. Unattended operation significantly reduces operating costs, but at the same time, there is the problem of equipment theft prevention. How to prevent theft and how to track the equipment after theft is particularly important for this type of equipment. This patent solves the problem of how to equip with stable and effective positioning tracking on the basis of anti-theft alarm. [0003] At present, there are many positioning tracking systems on the market, which generally send positioning information based on GPS positioning and cellular data network, such as Chinese patent documents CN 1...
