Description

AV System and Debugging Data Transmission Method

The present invention relates to an AVN system, and more particularly, to an AVN system capable of transmitting debugging data through Bluetooth communication in an engineering mode and a method of transmitting the debugging data.

In general, the AVN system provided debugging data in UART communication informing the operation status of the program, the interworking antenna, whether there is an error in each unit, the system down or holding position, and the memory status.

Therefore, the conventional standard system disassembles a vehicle, connects a standard board with a debugging board providing UART communication, and connects the debugging board with a computer of an engineer who performs debugging to perform debugging.

In other words, the conventional standard system has to make a separate debugging board, there is inconvenience such as disassembling the vehicle for debugging.

In order to solve the above problems, an object of the present invention is to provide an AVN system and a method for transmitting the debugging data that can transmit debugging data via Bluetooth communication in the engineering mode.

An audio video navigation (AVN) system according to an aspect of the present invention includes a processing unit for executing an engineering mode according to a user operation; And a Bluetooth module for transmitting debugging data through Bluetooth communication in the engineering mode.

According to another aspect of the present invention, a method of transmitting debugging data of an audio video navigation (AVN) system includes: entering an engineering mode; In the engineering mode, requesting to execute debugging; Bluetooth communication is started, pairing with a computer to be debugged; And when the pairing is completed, transmitting debugging data to the computer.

According to the present invention, it is possible to provide debugging information through the Bluetooth communication in the engineering mode, does not require a separate debugging board and cable, and does not need to release the body for debugging, it is easy to access debugging It has an effect.

Hereinafter, an AVN system according to an embodiment of the present invention will be described with reference to FIG. 1. 1 is a block diagram illustrating an audio video navigation (AVN) system according to an embodiment of the present invention.

As shown in FIG. 1, the AVN system 10 according to an exemplary embodiment of the present invention includes a central processing unit 110, a memory 120, a Bluetooth module 130, a screen processing module 140, and a sound module 150. , GPS module 160 and power module 170.

The central processing unit 110 executes the engineering mode according to a user's operation such as a keyboard operation or a button press.

The memory 120 stores information related to the execution of the AVN system 10 including the engineering mode.

The Bluetooth module 130 transmits debugging data to a computer to be debugged through Bluetooth communication in the engineering mode. At this time, the Bluetooth module 130 pairs with the computer performing debugging, and then transmits debugging data to the paired computer.

Here, the debugging data includes position information, time information, program operation state information, error information, transmission / reception information, and the like.

The screen processing module 140 displays each menu of the engineering mode on the display screen in the engineering mode at the request of the central processing unit 110.

The sound module 150 expresses the sound related to the selection of each module in the engineering mode, the warning about the occurrence of an error, the entry into the engineering mode, and the speaker at the request of the central processing unit 110.

The GPS module 160 provides vehicle position information in the engineering mode.

The power supply module 170 supplies power to each component of the AVN system 10 in the engineering mode.

As described above, the present invention can provide debugging information through the Bluetooth communication in the engineering mode, does not require a separate debugging board and cable, and does not need to release the vehicle body, it is easy to access debugging.

Hereinafter, each menu of the engineering mode will be described with reference to FIGS. 2A and 2B. 2A and 2B are diagrams illustrating respective menus of an engineering mode displayed on a display screen, respectively.

Each menu of the engineering mode is shown in FIG. NAVI), Bluetooth (BT), automotive ubiquitous system (CUBIS), debugging messages, etc., as shown in Figure 2b, GPS / DR status, GPS / DR trajectory, current location modification, memory status window, AMOS or the like.

As such, the AVN system 10 of the present invention may provide debugging data for a module displayed in each menu, and at this time, provides debugging data for a menu selected by a user.

Hereinafter, a debugging data transmission method of an audio video navigation (AVN) system according to an embodiment of the present invention will be described with reference to FIG. 3. 3 is a flowchart illustrating a debugging data transmission method of an AVN system according to an embodiment of the present invention.

Referring to FIG. 3, the AVN system 10 enters an engineering mode according to a user's manipulation (S310).

Subsequently, the AVN system 10 receives a debugging execution request RUN in the engineering mode (S320). In this case, the user may select a module to be debugged in the engineering mode and request debugging to execute the selected module.

In addition, the AVN system 10 pairs with a computer (eg, a notebook) to perform debugging through Bluetooth communication (S330).

When the pairing is completed and enters the data transmission mode, the AVN system 10 transmits debugging data to the computer to be debugged (S340). Here, the debugging data may be related to at least one of location information, time information, program operation state information, error information, and transmission / reception information.

At this time, the AVN system 10 transmits debugging data using the serial port profile of the Bluetooth module.

In this case, the computer to be debugged may store debugging data in a memory and perform debugging using the same.

Then, when debugging is completed by the computer to be debugged, the AVN system 10 may operate in a normal mode instead of an engineering mode.

As described above, the present invention can provide debugging information through the Bluetooth communication in the engineering mode, and there is no need to connect a separate debugging board and cable or perform a process of releasing the vehicle body, thereby easily accessing debugging. have.

While the present invention has been described in detail with reference to the accompanying drawings, it is to be understood that the invention is not limited to the above-described embodiments. Those skilled in the art will appreciate that various modifications, Of course, this is possible. Accordingly, the scope of protection of the present invention should not be limited to the above-described embodiments, but should be determined by the description of the following claims.
