Description

Multi black box with MDR module {MULTI BLACK BOX MOUNTED MDR MODULE}

The present invention relates to a multi-black box equipped with an MDR module, and more particularly, to a multi-black box equipped with an MDR (Multi Driving Recorder) module in which a wireless communication technology and a vehicle's self- And performs wireless communication with terminals outside the vehicle interacting with the MDR module in a bidirectional manner. Thus, it is possible to provide a self-diagnosis service of a user, a service inspection service of a vehicle repair shop, an anti-theft service by location tracking, To a multi-black box equipped with an MDR module.

In general, a black box device is a typical flight recorder that records the performance and condition of an aircraft in flight. Recently, a black box device has been used in vehicles such as automobiles as well.

The vehicle black box device records information on the running state of the vehicle and the accident situation, thereby enabling a more accurate determination of the state of the vehicle accident based on the record stored in the black box when a vehicle accident occurs.

However, the conventional vehicle black box device has a disadvantage in that the device is used only by recording information only when a vehicle accident occurs during the vehicle's operation.

In addition, the conventional vehicle black box device can not accurately analyze an accident type for a vehicle when investigators analyze an accident cause by providing only a recorded image after an accident, There was no problem.

In addition, since the conventional black box device for a vehicle can not constitute a module to be interlocked with a smartphone or the like, which is popular in recent years, it is possible to provide a self-diagnosis service for a user, a service inspection service for a car repair shop, Home service, and so on.
