Therefore, the data server 400 grasps the expected failures by considering the frequency of each post code, the situation in which each post code is repeated, and the change pattern of the post code. By doing so, information capable of taking precautionary measures may be transmitted to the user portable terminal 300.

In general, the post code (POST CODE) consists of two hexadecimal digits.

For example, the first post code 0x1A, the second post code 0x2A, the third post code 0x3A, and the fourth post code 0x4A are sequentially set as the first reference pattern, and the change pattern may periodically coincide with the first reference pattern. In this case, it is assumed that there is a high possibility of a malfunction of the memory.

At this time, the post code of the first reference pattern must occur in order, and whether the change pattern matches the first reference pattern by using the post code generated during a period of at least 1 day up to 3 months. To confirm. At this time, the period may be extended or shortened.

The first reference pattern is basically stored in the data server 400, and is continuously updated with feedback.

That is, when the repair technician repairs the user's computer, the failure symptoms are transmitted to the data server 400 using the repair technician terminal, so that the data server 400 post code generated before the repaired computer is repaired (POST CODE ), You can create and update the reference pattern.

If the second reference pattern is composed of 10 sequential post codes (POST CODE), that is, when the reference pattern is made of at least 3 or more post codes (POST CODE), it is determined whether the change pattern matches or not as well as similarity. do. That is, even when the change pattern is 80% or more similar to the second reference pattern, it is transmitted to the portable terminal 300 that there is a possibility that a failure symptom assigned to the second reference pattern may occur.

For reference, if the change pattern and the second reference pattern do not coincide and are similar, the portable terminal 300 indicates that a failure symptom may occur in a probability unit.

Meanwhile, when the captured image of the main board 100 for a computer is transmitted from the portable terminal 300, the data server 400 may operate to determine which type of main board through the image recognition to determine the hardware model. have. That is, the basic information of the computer hardware can be recognized through a QR code or a barcode, but when the information is not in the database, the data server 400 receives the captured image of the portable terminal 300 and recognizes the hardware type through image recognition. Can also be identified.

In addition, the error detection device 200 additionally collects data such as each voltage of the main board, the rotation speed of the cooling fan, the temperature of the main board, and hard disk information (HDD-SMART), as well as the post code. By storing and providing the corresponding information to the portable terminal 300 and the data server 400, it is possible to accurately analyze and prevent the failure symptoms.

In addition, the error detection device 200 utilizes a built-in storage medium as a recovery area of the system operating system, and provides a function to emergency boot to the built-in real-time operating system (LIVE OS) when the main storage device fails. can do.

The computer fault diagnosis system using the PCI-E interface according to an embodiment of the present invention visually displays a post code (POST CODE), and connects to a data server through a diagnostic application, and corresponds to a failure corresponding to the post code (POST CODE) Since the diagnosis result can be checked, even a normal user can easily check and cope with what part of the hardware is in trouble.

That is, the computer fault diagnosis system 1 obtains POST-CODE data output to the I / O port 80h of the computer main board from the PCI-E interface and records it in its own storage medium, and transmits this data over the network.
