Automatic diagnosis system and method thereof

1. An automatic diagnosis method implemented by an automatic diagnosis system, wherein the automatic diagnosis system comprises a network device and a portable storage device, the automatic diagnosis method comprising:

detecting whether the portable storage device is plugged into a transmission interface of the network device;

when it is detected that the portable storage device is plugged into the transmission interface of the network device, executing a system program via the network device, so that the system program loads and executes a diagnosis program stored in the portable storage device;

analyzing a network condition of the network device by the diagnosis program to generate a status report;

writing the generated status report to the portable storage device; and

utilizing the diagnosis program to diagnose the network condition and fix network issues in response to results of the diagnosis, wherein a system model of the network device comprises an application layer, a kernel layer, a middleware layer, and a driver layer, and the diagnosis program is a dynamic-link library file in the middleware layer, which is between the driver layer and the kernel layer, and the diagnosis program manages the driver layer and the kernel layer.

2. The method as claimed in claim 1 , wherein before loading and executing the diagnosis program, the method further comprises:

detecting whether the portable storage device has stored the diagnosis program, and qualifying authorization of the diagnosis program; and

when the authorization of the diagnosis program is qualified, decrypting the diagnosis program.

3. The method as claimed in claim 1 , wherein the status report comprises multiple network settings and/or the analyzed network condition of the network device.

4. An automatic diagnosis system, comprising:

a network device comprising:

a processor;

a memory unit;

a storage unit configured to store a system program; and

a transmission interface; and

a portable storage device,

wherein the processor detects whether the portable storage device is plugged into the transmission interface,

wherein when it detected that the portable storage device is plugged into the transmission interface, the processor executes the system program, so that the system program loads and executes a diagnosis program stored in the portable storage device, and

wherein the processor further executes the diagnosis program to analyze a network condition of the network device to generate a status report, and writes the generated status report to the portable storage device,

wherein the processor utilizes the diagnosis program to diagnose the network condition and fix network issues in response to results of the diagnosis,

wherein a system model of the network device comprises an application layer, a kernel layer, a middleware layer, and a driver layer, and the diagnosis program is a dynamic-link library file in the middleware layer, which is between the driver layer and the kernel layer, and the diagnosis program manages the driver layer and the kernel layer.

5. The automatic diagnosis system as claimed in claim 4 , wherein before loading and executing the diagnosis program, the processor further detects whether the portable storage device has stored the diagnosis program,

wherein when it is detected that the diagnosis program has been stored in the portable storage device, the processor further qualifies authorization of the diagnosis program, and

wherein when the authorization of the diagnosis program is qualified, the processor further decrypts the diagnosis program.

6. The automatic diagnosis system in claim 4 , wherein the status report further comprises multiple network settings and/or the analyzed network condition of the network device.
