Description

LTE Fault Detection Device The present invention relates to an LTE fault detection device, and more specifically, to an LTE fault detection device capable of identifying a terminal where an error occurred when an error occurs in a plurality of terminals based on LTE communication. Existing terminal error detection methods using oscilloscopes require the ability to read waveforms, and it is somewhat difficult for ordinary people without specialized knowledge of LTE to acquire an oscilloscope, obtain waveforms through it, and determine errors. In addition, the error detection method using an oscilloscope has the inconvenience of being unable to identify the terminal where the error occurred when an error arises in a terminal connected via LTE communication, making it impossible to verify which product is functioning normally among multiple terminals connected via LTE communication. Figure 1 illustrates two terminals connected to an LTE network via two RJ45s. Figure 2 illustrates a waveform to explain a method for detecting an error using an oscilloscope. Figure 3 shows the waveform measured when an actual error occurs using an oscilloscope. Figure 4 is an enlarged view of the waveform measured from a terminal connected to and communicating via Auto MDX. Figure 5 is an enlarged view of the waveform measured from a terminal connected to and communicating via Auto MDIX. FIG. 6 illustrates an LTE fault detection device according to one embodiment of the present invention. FIG. 7 illustrates an LTE fault detection device according to one embodiment of the present invention. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The advantages and features of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components. Unless otherwise defined, all terms used herein (including technical and scientific terms) may be used in a meaning commonly understood by those skilled in the art to which the present invention pertains. Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise. The terms used herein are for describing embodiments and are not intended to limit the present invention. In this specification, the singular form includes the plural form unless specifically stated otherwise in the text. As a method for detecting errors occurring in a terminal connected via LTE communication, the occurrence of an error can be determined by measuring a waveform using an oscilloscope (hereinafter referred to as "oscilloscope"). An oscilloscope is a device that records or displays vibration phenomena so that they can be seen visually, and enables observation by converting vibrations into voltage signals. A method for detecting errors using an oscilloscope will be explained with reference to FIGS. 1 to 5. Figure 1 illustrates two terminals connected to an LTE network via two RJ45s. Figure 2 illustrates a waveform to explain a method for detecting an error using an oscilloscope. Referring to FIGS. 1 and FIGS. 2, when the physical layer protocol (PHY) of the first terminal (10) among the first terminal (10) and the second terminal (20) that are normally connected is forcibly reset, a waveform like FIG. 2 appears from the oscilloscope. First, to detect a link down using an oscilloscope, one probe of the oscilloscope is placed in front of the link down LED to check for a link down, and the other probe is placed at RXD and TXD. RXD is a line for data transmission, and TXD is a line for reception, and terminals (10, 20) are connected to it. Specifically, when an error occurs in one or more terminals among multiple terminals connected via LTE communication or when the physical layer protocol is reset, a waveform such as that shown in FIG. 2 can be obtained through an oscilloscope, and a link down occurs first in the first terminal (10) and a link down occurs in the second terminal (20) with a time difference (A) of 4 μs. Referring to FIG. 2, after the voltage of the link (10a) of the first terminal rises, the TXD (10b) signal of the first terminal is cut off, the TXD (20b) signal of the second terminal is cut off, and the voltage of the link (20a) of the second terminal rises. Figure 3 shows the waveform measured when an actual error occurs using an oscilloscope. Figure 3 shows the wa
