Embodiment 1

[0024] according to figure 1 The flow shown is a method for judging three urgent events and uploading data under traffic restrictions, including the following steps:

[0025] S1: According to the terminal data collection frequency, determine the queue lengths of three sensors: rapid acceleration, rapid deceleration, and sharp turning; the terminal data collection frequency is 10HZ, the sensor data queue length is 100, and the acceleration obtained by collection is linear acceleration.

[0026] S2: Determine the three emergency event data filtering thresholds, namely rapid acceleration, rapid deceleration in the forward direction, and lateral sharp turning acceleration; the longitudinal acceleration thresholds of the three emergency event filters in this embodiment are, rapid acceleration: 1m / the s 2 , rapid deceleration: 2m / s 2 , the lateral acceleration is used for sharp turns: 0.5m / s 2 .

[0027] S3: Compare the three values ​​of rapid acceleration, rapid deceleration a...

Embodiment 2

[0033] The same equipment as in Embodiment 1, and the same filtering threshold settings.

[0034] In step S3, the value sent to the service platform is encrypted, and in step S4, the three values ​​of rapid acceleration, rapid deceleration, and sharp turn are decrypted before the three urgent event judgments, which can further ensure data leakage; at the same time, In step S3, the measured queue data of the three values ​​of rapid acceleration, rapid deceleration, and sharp turn are symmetrical around the time point of the event, taking data of 5 seconds before and after the event, and the amount of queue data is 100.

[0035] In step S4, the service platform encrypts the measured values ​​of rapid acceleration, rapid deceleration and sharp turn, and the decoded data are sorted by time and stored in the database of the service platform for further analysis and use.

[0036] In order to ensure the data transmission rate, the service platform and the R server service device are ...

Abstract

The present invention discloses an intelligent detection and data transmission method, and particularly relates to a traffic limitation-based method for determining three urgent events and uploading data. The method comprises the steps of determining a length of a sensor queue according to terminal data acquisition frequency, and determining, according to a three-urgent model, a sensor data filtering threshold; determining a threshold of a sensor data flow according to the filtering threshold, if the threshold meets the filtering threshold, extracting data of the sensor queue, and if the threshold does not meet the filtering threshold, determining the threshold continuously; encrypting and uploading the extracted data of the sensor queue to a service platform, and after the data is received, decoding, by the service platform, the data and storing the decoded data in a database; and invoking, by the service platform according to a request, an R server service to determine the three urgent events, and returning and storing obtained event data in the database. Through adoption of the method, the driver is safer.

Description

technical field [0001] The invention relates to an intelligent detection and numerical value transmission method, in particular to a method for solving three emergency event judgments and data uploading under traffic restrictions. Background technique [0002] With the rapid development of the economy, China has gradually developed into one of the largest automobile markets in the world. The number of automobiles is relatively large, and the growth potential of automobiles is huge. While the number of automobiles is increasing, the traffic accident rate is also increasing. In order to reduce traffic accidents, it is necessary to improve drivers' safety awareness and help drivers develop good driving habits. Before carrying out these tasks, it is first necessary to understand the driver's driving habits, or driving behavior, in order to be able to guide the establishment of good driving habits in a targeted manner. [0003] The three-urgent events (rapid acceleration, rapid ...
