Vehicle fault diagnosis and alarming help system

Abstract

The invention discloses a vehicle fault diagnosis and alarming help system which comprises an automatic vehicle body diagnosis device, a master electronic control unit (ECU), a remote monitoring center, a communication unit, a display unit and alarms. The automatic vehicle body diagnosis device is used for collecting vehicle state data and driver driving behavior data. A vehicle state detecting system comprises a vehicle-mounted GPRS system, a pollution discharge information collecting device, a vehicle data recorder and a navigation radar. The alarms are arranged on a driver seat and passenger seats, each alarm is provided with a camera and an emergency intercom key, and each alarm is internally provided with a POE unit, a low-power microprocessor, a noise detecting unit, a loudspeaker, a microphone and a storage unit. After adopting the structure, road surface states and the distances between a vehicle body and front and back vehicles or obstacles can be detected in real time, so that driving is safer and more reliable.

Description

technical field [0001] The invention relates to a vehicle fault diagnosis and alarm device, in particular to a vehicle fault diagnosis and alarm and help-seeking system. Background technique [0002] According to the requirements of GB / T19056-2012 of the Ministry of Public Security, it is currently mandatory to install a driving recorder on long-distance passenger and freight vehicles, especially "two passengers and one dangerous" vehicles, to record the position, speed and various driving conditions of the vehicle during operation , to store the data in the terminal memory. According to the requirements of JT / T794-2011 of the Ministry of Communications, the recorded information can be sent to the monitoring service background in real time through wireless transmission. [0003] Vehicle-mounted terminals that only meet the requirements of national and ministry standards cannot meet all the requirements for monitoring and management of operating vehicles and improving transp...

AI Technical Summary

Problems solved by technology

[0005] (2) The driving assistance function is too simple

At present, the driving recorder can only record audio and video, so that it can be restored on the spot when there is a dispute

In addition, the navigation radar is only used when reversing, which is convenient for reversing and has a single function, resulting in idle waste of resources

[0006] (3) Insufficient vehicle driving information processing and information mining capabilities

[0007] Therefore, the current driving recorder and navigation radar are relatively single in function and cannot meet many requirements for monitoring and management of operating vehicles and improving transportation safety. This application has effectively improved

[0008] In addition, when drivers or passengers encounter special circumstances and need to call the police for help, they usually use their own mobile phones to call the police. However, at present, smart phones have a short standby time and often run out of power. For a long time, it is easy to delay the preservation of the best alarm scene, the frontal video image of the alarm personnel cannot be obtained, and it is difficult to trace after the event.
