Embodiment Construction

[0034] The following is attached figure 1 and figure 2 The present invention is further described.

[0035] Process 1: Install the node. The positioning nodes are powered by batteries, report wirelessly, and can be quickly installed without modifying the vehicle.

[0036] Process 2: Download APP (divided into Android and IOS), and register. Registration information includes avatar, mobile phone number, password, user name, device ID and vehicle notes. Among them, the client will process the avatar as a unified standard first, and then the user can modify it by himself. Mobile number and password are used for login. The username is used to better identify the user. The device ID is used to bind devices, and the same account can bind multiple devices. The vehicle remark is convenient for users to distinguish vehicles, see image 3 .

[0037] Process 3: After installing the positioning node and completing the registration, the user can turn on the mobile phone to view t...

Abstract

The invention discloses a vehicular intelligent antitheft tracking alarm system based on BT-IoT (narrow band internet of things). A positioning node is used as a vehicle front-end tracking device to acquire the position of a vehicle front end through GPS (global positioning system) or Beidou satellite; daily trip trajectories are learned through a machine learning algorithm; in case of theft risk,the positioning node judges the position by a displacement sampling timer; GPS data are read once every 300 seconds and are compared with a previous positioning coordinate point; when a coordinate point difference exceeds a specified threshold, it is determined that a vehicle moves; the positioning node reports a movement notification; a control center sends a vehicle movement reminding short message to a user. The NB-IoT is used herein to solve the problems of the prior art, including failure indoor positioning, high equipment cost, high equipment consumption, short battery life and installation complexity; rules of vehicle usage are learned through a machine learning algorithm, so that energy saving is achieved; the trip trajectories are learned to enhance theft prevention.

Description

technical field [0001] The invention relates to an NB-IoT-based vehicle tracking alarm system, which belongs to a vehicle anti-theft device based on a cellular network-based Narrow Band Internet of Things (NB-IoT). Background technique [0002] The most popular electric vehicle anti-theft device on the existing market is realized through GPS and GPRS. Its characteristic is that once citizens find that the electric vehicle is lost, they can quickly locate the current location information of their electric vehicle through the mobile phone APP. However, the problem with this device is that due to the high power consumption of GPRS, the battery power supply generally can only be used for one week to half a month, which cannot meet the needs of users at all, and can only rely on the battery power of the electric vehicle. Therefore, the device generally needs to be directly connected to the vehicle battery, and positioning monitoring can only be realized through a complicated tran...
