FIGS. 2A through 2C are diagrams illustrating a generation unit of a performance monitoring system of a communication module according to various embodiments of the present invention.

Hereinafter, preferred embodiments of a performance monitoring system for a communication module according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a performance monitoring system of a communication module according to a preferred embodiment of the present invention. And FIGS. 2A through 2C are diagrams illustrating a generation unit of a performance monitoring system of a communication module according to various embodiments of the present invention.

1, the performance monitoring system of the communication module includes a generating unit 30 for generating raw data, a collecting unit 40 for generating processed data, and a user interface unit for displaying processed data 50).

When the first communication module 10 performs WAVE communication with the second communication module 20 and other communication modules in an environment where a plurality of communication modules can perform WAVE communication with each other, 10 from the first communication module 10 in order to confirm the performance of the first communication module 10.

Here, as shown in FIGS. 2A to 2C, the generator 30 may be implemented in various forms. In FIG. 2A, the generation unit 30 is provided in the first communication module itself, so that it can collect and generate data information from the first communication module without a different communication medium.

2B, the generation unit 30 is formed separately from the first communication module 10 and can be connected to the first communication module 10 through a separate communication medium to collect and generate data .

At this time, there is no restriction on the type of communication medium connecting the two devices. Lastly, referring to FIG. 2C, the generator 30 is not configured as a device like the first communication module 10, but is configured as an application program installed in the first communication module 10 . In this case, a control unit (not shown) for driving the application program may be included in the first communication module 10, but a control unit (not shown) in the existing first communication module 10 It is also possible to drive the application program.

The data generated by the generator 30 includes location information of the first communication module, signal strength value of another communication module (including the second communication module) received by the first communication module, packet transmission / reception time, The number may be included. The position information of the first communication module 10 is information necessary for knowing the current position of the vehicle on the assumption that the vehicle on which the first communication module 10 is mounted is moved in the V2X communication. Specifically, GPS information is used .

In addition, the signal strength value means a received signal strength indication (RSSI), which is a value obtained by measuring the signal strength of another communication module coming into the first communication module 10. In addition, the information about the packet is used as data for confirming whether or not the data transmission is properly performed. However, any data for confirming the performance of the communication module is said to correspond to the above data and is not limited to the above examples.

The data is transferred from the generator 30 to the collector 40. The collecting unit 40 processes the raw data to generate and store the processed data. More specifically, the collecting unit 40 may include an operation unit 41 and a storage unit 42. The operation unit 41 may receive the packet data from the packet transmission / reception time Calculates a round trip time (RTT), and calculates a packet error ratio (PER) from the number of transmission / reception packets. The processed data such as the calculated RTT and PER values are stored in the storage unit 42 together with the remaining data.

The RTT is a function that the packet is transmitted from the first communication module 10 to the destination communication module via an intermediate node or a communication network, Means the time until reaching the communication module 10. RTT can be calculated through the expression "RTT = packet reception time - packet transmission time". The PER indicates the ratio of the total number of packets transmitted from the first communication module 10 to the number of packets lost without being returned to the first communication module 10 after being transmitted to the destination communication module.

In more detail, the user interface unit 50 may include a buffer 51 and a display 52.

The buffer 51 is a storage medium used as a temporary data storage place when transmitting information such as data, and can be used to compensate for a difference in time or a difference in data flow rate when data is transmitted from one apparatus to another apparatus have. Accordingly, the buffer 51 stores the machining data received from the collecting unit 40, and transmits the machining data to the display 52 at predetermined intervals set by the user. The display 52 displays the processed data to the user whenever the processed data is received from the buffer.

The mathematical numerical value may be displayed on the display 52 by a micro controller unit (MCU), which can be mounted on the display 52, in order to facilitate the understanding of the system user according to the present invention. Not shown), and displayed on a graph or a drawing.
