Description

[0001] The present invention relates to a web-based black box and a system for interworking between a mobile terminal and a web-based web-based black box,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a web-based black box for a vehicle, and more particularly to a method for linking a portable terminal and a web-based black box for a vehicle.

In general, a vehicle black box is used for post-accident post-processing and scientific accident analysis by recording the state before and after a vehicle collision accident. Recently, the importance of the vehicle black box has been strongly recognized along with a sudden increase in vehicle accidents.

In particular, since the data recorded in the vehicle black box is used as the data for analyzing the cause of the accident, and is used as evidence for solving various civil-related disputes, it is expected that the vehicle black box will be popularized in the future .

Typically, a memory for storing various information is mounted on a vehicle black box, and image data obtained by photographing the front or side of the vehicle and other vehicle driving information are stored in the memory. For reference, the vehicle operation information may include not only normal vehicle operation information but also vehicle operation information before and after an accident in the event of an accident.

On the other hand, the vehicle black box maintains the recording status constantly in the state of parking or stopping, thereby preventing the theft or the damage of the vehicle in advance, and in the case of the vehicle equipped with the black box, It is expected.

However, in the conventional black box, it is necessary to remove the storage medium storing the photographed image from the main body and check it on the PC in order to confirm the accident image and submit it as backup or forensic evidence. To solve this problem, In order to easily identify and store images, a black box technology using a wireless communication scheme, Wi-Fi technology, has been proposed.

A conventional Wi-Fi black box having a function of searching recorded information by wireless communication with a portable terminal (in particular, Wi-Fi) can be classified into a first-generation Wi-Fi black box and a second-generation Wi-Fi black box.

First, a first-generation Wi-Fi black box is a black box using only an FTP (File Transfer Protocol) server. The first generation Wi-Fi black box is advantageous in that it can transmit and receive image files without removing an SD card, There is a problem in that the FTP client software is necessarily required for the terminal, and in particular, there is a problem that it is difficult to use even the black box users having such a function because the FTP setting method is difficult. In particular, in the case of the first generation Wi-Fi black box of the FTP type, only a list (a directory) of recorded files is provided, so that it is difficult to intuitively grasp the file desired by the user.

Next, the second-generation WiFi black box, which has partially improved the problems of the first generation black box, is a black box adopting a method of receiving a client application using an FTP (File Transfer Protocol) server and an RTSP (Real Time Streaming Protorol) The biggest difference compared to the generation black box is that it provides easy access to FTP or RTSP by providing dedicated software to portable terminals such as smart phones so that users can access easily.

In particular, in the case of the second-generation black box, the image file can be transmitted and reproduced without removing the storage medium such as the SD card, and the image recorded in the black box by the RTSP can be confirmed in real time through the portable terminal. This makes it possible to easily adjust the shooting angle when mounting the black box.

However, in the case of the second generation black box, the black box maker has to separately provide applications of various types of smartphone OS, and the application is updated every time the OS is upgraded after the application of the OS is installed There are some inconveniences that have to be given, and when the OS is not available for a long time, it is very likely that the black box will become useless.

Patent application number: 10-2011-0038969 Title of the invention "Closed two channel black box camera system using WiFi"

In the present invention, a web-based black box for a vehicle is used as a wireless access point (AP). Accordingly, a driver selects a web-based black box network in a portable terminal, inputs a predetermined password, .

Then, a predetermined web browser installed in the portable terminal is activated to confirm the image or the recorded image photographed by the web-based black box through the wireless WiFi communication with the portable terminal.

In the present invention, a web browser refers to a web browser generally used in a portable terminal such as a personal computer or a smart phone such as Internet Explorer, Firefox, Safari, and Chrome.

When the web browser of the portable terminal is executed and any English domain address such as an arbitrary home page address (for example, next, Naver, Nate, key fris, patent office, etc.) is activated, And transmitted to the DNS server 110.

When the DNS server 110 according to the present invention receives the arbitrary domain address from the portable terminal in the state of being paired with the portable terminal, the DNS server 110 according to the present invention transmits a predetermined web server IP address (a specific web server IP address, for example, 192.168.1.1 To the portable terminal.

Here, the predetermined web server IP address is an IP address that can call a predetermined web page 130 on which predetermined web pages stored in the black box 100, that is, functions for controlling the operation of the black box, are loaded .

The web server IP address transmitted to the mobile terminal and displayed in the web browser is retransmitted to the web-based black box 100.

The web server 130 accesses a predetermined web server 120 (which is a web server having the web server IP address) mounted in the black box according to the web server IP address retransmitted from the portable terminal to the black box, Calls a web page (which is a predetermined web site mounted in the black box) and transmits it to the web browser of the portable terminal.

Accordingly, the driver can select predetermined function buttons on the web page transmitted to the portable terminal and call the recorded image of the black box or the like.

In the present invention, a web page may include various functions that can be performed on a web-based computer. For example, on the web page, there are a current image view button for viewing a current image being captured, a system button for viewing system information of a file button black box for viewing a recorded image list, An environment setting button, and the like.

Here, the expression 'button' means an item displayed on a web page or the like, and on the portable terminal equipped with the touch screen, the command request can be transmitted to the black box by wireless WiFi communication by selecting by the touch, In response to the request, information corresponding to the request is transmitted to the mobile terminal by wireless Wi-Fi communication.

The black box 100 responds to the request, Can be transmitted to the portable terminal.

For reference, the web-based black box implemented in the present invention basically has a FTP (File Transfer Protocol) server and a real-time RTSP (real time streaming protocol) server function used in the existing black box.

However, in the present invention, there are only differences in that all of them are made operable on a web-based basis.

In the above-described embodiment, a DNS server and a web server (for example, an HTTP server) are driven to provide a black box equipped with a predetermined web page so that a web-based service can be performed.

The web-based black box of the present invention is remarkably different from the second-generation black box mentioned in the prior art. Unlike the second-generation black box, which provides predetermined dedicated software for accessing FTP or RTSP, Is a method of driving a predetermined web page (for reference, it is also possible to provide a predetermined web application line in practice).

That is, in the case of a conventional second-generation black box implemented as an app-based system, a black box manufacturer must separately provide applications of various types of smartphone OSs, and when the OS is upgraded after an application of the OS is installed There is a problem that the corresponding application needs to be updated every time. However, the web-based implementation of the present invention as described in the present invention has an advantage in that all the inconveniences are solved when the mobile terminal is linked with the mobile terminal.

In particular, the FTP function used in the second generation black box has a problem that it is difficult to retrieve a desired recorded image in a short period of time because the storage list is simply displayed in text form. However, in the present invention, (Thumb Nail) function which is not provided by the existing FTP through the conventional FTP. Therefore, there is an advantage that it is possible to easily search a recorded file while viewing a specific image from among a plurality of recorded images. In addition, It is also possible.
