Abstract

The present invention provides a parking vehicle collision alarm method based on NB-IoT technology. The vehicle-mounted data collection terminal collects collision amplitude data through a sensor. After judging that the data is true, the customer management server cluster sends alarm information to the mobile smart terminal. Establish a model database in advance, analyze and compare the collision amplitude data, so as to obtain the location, type and degree of the collision, and judge the authenticity of the data through the cloud computing server, thereby reducing false positives and missed negatives.

Description

technical field [0001] The invention belongs to the technical field of parking alarms, in particular to a collision alarm method for parked vehicles based on NB-IoT technology. Background technique [0002] In the prior art, after the vehicle is collided by other vehicles, falling objects, foreign objects, etc., the registration alarm system collects the collision data and judges whether the collision data is greater than the threshold, and if the value is greater than the threshold, it will send a warning to the owner. However, there are the following problems in the prior art: the cost of existing data communication methods such as 3G and 4G is relatively high, the bandwidth resources are occupied a lot, and the standby time is short. In addition, the existing judgment process is simple, and the false positive rate and false negative rate are high. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a collisi...
