Compared with the prior art, the invention has the advantages of high monitoring precision, accurate positioning, etc.

Description

technical field [0001] The invention relates to a vehicle driving behavior monitoring terminal, in particular to a multi-sensor remote vehicle driving behavior monitoring terminal. Background technique [0002] At present, the terminal products of vehicle driving behavior usually adopt satellite positioning technology, communication technology such as GSM, CDMA, 3G, etc. and microprocessor (MCU). The basic functions of the main products are equivalent, including vehicle positioning, OBDII information collection and uploading and other functions. . [0003] The current technical status of the product is as follows: [0004] 1) Usually the overall electrical structure is power supply, GPS module, GSM, microprocessor, etc., which are connected to the vehicle through the vehicle OBD interface, and obtain power supply and read vehicle engine and other data; [0005] 2) Usually, positioning data and vehicle data are sent to the monitoring platform for processing; [0006] 3) Us...

AI Technical Summary

Problems solved by technology

[0006] 3) Using a single satellite positioning technology, without using ground DGPS signals to obtain more accurate positioning information;

[0007] 4) Use a single satellite positioning technology to obtain vehicle operation data. In areas with poor satellite signals, it is impossible to obtain vehicle movement patterns and analyze driving behavior;

[0008] 5) Lack of means to directly obtain the acceleration of the vehicle;

[0009] 6) Lack of means to directly obtain the turning speed of the vehicle;

[0010] 7) The lack of real-time driving records is not conducive to the analysis after the accident;

[0011] 8) Equipment lacks remote upgrade means
