The devices 240 are connected to each other via a serial communication line 230 to transmit and receive data with the PC 210 and to receive specific information of the auxiliary PCs 220-1 to 220-n.

The dedicated maintenance device 240 includes a screen for displaying an operation state and an input device for setting a specific function, as well as a PCB 210 and an auxiliary PCB 220 that are put into a wire to facilitate history management for each wire. Built-in information database (DB) 241 for storing information related to 1 to 220-n, and such a device is provided with a GUI (Graphic User Interface) based program.

The auxiliary PCs 220-1 to 220-n do not necessarily need to be connected, and even when connected, the number or type may be changed according to circumstances.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

3 is an overall operation flowchart for an embodiment of the present invention, which will be described below.

After connecting the PC 210 and the dedicated repair device 240 through the serial communication line 230 and turning on the power repair device 240, the power repair device 240 may perform maintenance or security related work. In operation S31, it is determined whether the communication state with the PC 210 is normal.

At this time, if it is determined that the communication state is not normal, the dedicated maintenance device 240 terminates the work and displays it as a character or figure on the screen.

On the contrary, if it is determined that the communication state is normal, the dedicated maintenance device 240 waits for a specific key press on the input device.

In this case, if it is recognized that the key is pressed in the input device, it is determined whether the repair-related work (S32).

Accordingly, if it is determined that the maintenance-related work, the dedicated maintenance device 240 ends after performing the maintenance-related work (S33).

In addition, if it is determined that the repair-related operation is not the dedicated maintenance device 240 determines whether the security-related operation (S34).

At this time, if it is determined that the security-related tasks are not, the dedicated maintenance device 240 terminates all the tasks and displays them as characters or figures on the screen.

On the contrary, if it is determined that the security-related operation in the process (S34), the dedicated maintenance device 240 generates a random check that is one of the user approval tasks required for security, transmits to the PCB 210 and waits for the decryption key input. (S35).

Thereafter, if any decryption key is input and the input of the key is completed, the key input is checked whether the correct decryption key is input (S36).

Accordingly, if it is determined that the correct decryption key is not input, the dedicated maintenance device 240 not only terminates the work but also displays it as a letter or a figure on the screen. On the contrary, if it is determined that the correct decryption key is input, the security operation is performed (S37). And end the job.

4 is an operation flowchart for a security task according to the present invention.

Dedicated maintenance unit 240 is a PC 210 210 directly connected to the serial communication line 230 when the security operation is set by a specific key press of the input device and n auxiliary PCs 220-1 connected in parallel to the PC 210 (210) The identification name (Unique ID) of ˜220-N is read (S41).

At this time, the dedicated repairing device 240 reads the identification names of the PC 210 and the auxiliary PCs 220-1 to 220-N, and compares them with the lead-type identification names stored in the information database 241. It is made (S42).

If the identification name of each of the lead wires stored in the information database 241 and the identification names of the PCs 210 and the auxiliary PCs 220-1 to 220-n do not match, the PCs 210 or the auxiliary PCs 220 that are put into the lead wires are not matched. -1 to 220-n is determined that the product is not received through a legitimate procedure, and converts to a specific operation (S48), and then ends the security work.

On the contrary, if the lead identifications stored in the information database 241 in the process S42 match the recognition names of the PC 210 and the auxiliary PCs 220-1 to 220-n, the security information is previously executed to perform the security function. After performing the encryption process of the acquired recognition name (ID) (S43), it is checked whether there is already authorization data in the storage device 211 in the PC 210 (S44).

If it is determined in the step S44 that there is no approval data in the storage device 211, it means that the approval operation is performed for the first time. To complete the security function and then end the operation.

If the authorization data already exists in the storage device 211, it is compared whether or not the encryption value of the recognition name obtained above matches the authorization data (S45).

Therefore, if the encrypted value of the recognition name and the approval data match, the dedicated maintenance device 240 performs the approval operation (S46), terminates the security function, and ends the operation.

If the encryption value of the recognition name and the authorization data do not match in step S45, the process is converted to a specific operation and executed (S48).

On the other hand, the specific information of the lead wires PC 210 and the auxiliary PCs 220-1 to 220-n stored in the information DB 241 in the dedicated maintenance device 240 is the same as the example of FIG.

In this case, the specific information stored for each lead wire is sequentially stored in the PC 210 and the auxiliary PCs 220-1 to 220-n, and the identification names of the unconnected auxiliary PCs are initialized to be distinguished from the connected auxiliary PCs. .

At this time, the storage form of the specific information is by wire, but may be stored by the recognition name of the PC for efficient management.

In addition, the storage form of the approval data stored in the memory device 211 in the PC 210 is the same as the example of FIG.

If the PCB has not yet been approved through the security function, all of the memory devices 211 are filled with initial values.

That is, the memory device 211 stores a unique ID of the PC 210 and the auxiliary PCs 220-1 to 220-n through a security function, and the PCB that has completed the approval process is stored in the encryption process. The unique ID set by the user is stored.

Therefore, when the approval check routine is randomly performed in the PC 210 as shown in the operation flowchart of FIG. 4 with respect to the recognition ID (Unique ID) stored in the storage device 211 as described above, the storage device 211 is stored in the storage device 211. It is to determine whether to approve again by comparing the encrypted recognition value of the stored recognition recognition name and the newly read PCB 210 and the identification name (Unique ID) of the auxiliary PCBs 220-1 to 220-n.

7 is an operation flowchart for preventing illegal copying of a software program installed in the dedicated maintenance apparatus 240. This process will be described below.

When the program is to be executed in a maintenance or security related task, the PC 210 acquires a recognition name (CPU-ID) of the dedicated maintenance device 240 currently connected (S71) and acquires a recognition name (CPU) obtained at the time of installation. -ID) and compare (S72).

Here, the identification name (CPU ID) is a identification name (Unique ID) for distinguishing a dedicated maintenance device.

In this case, if the recognition name acquired at the time of installation and the currently acquired recognition name match, the PCB 210 checks whether the time using the program is less than a specific time (S73).

If the use time is less than a specific time in the process (S73), it is determined whether the number of times the program is used is less than a specific number of times (S74).

Accordingly, when the number of times of using the program is determined to be less than the specific number of times, the PCB 210 permits the execution of the program to the dedicated maintenance device 240 (S75) and ends the operation.

If the currently acquired recognition name and the acquired recognition name at the time of installation do not match, or it is determined that the program usage time is not less than a specific time or the number of program usage is not less than a specific number of times, the PCB 210 cannot execute the program. Notify the dedicated maintenance device 240 (S76) and ends the operation.

Here, the checking of the use time and the number of times of use of the program is to cope with the case where the dedicated maintenance device 240 is stolen.

In addition, when a maintenance and security program fails to execute, if the program is reinstalled by the maintenance company or the installation company, the maintenance and security program may be executed for a specific time or a specific number of times.

8 is an operation flowchart for a security function in a PCB, which will be described below.

When the security function in the PCB starts, the dedicated maintenance device 240 executes an approval check routine (S81), so that the authorization data as shown in the example of FIG. 6 is stored in the storage device 211 in the PC210. If there is a check (S82).

At this time, the acknowledgment function has already been acquired and randomly executes the approval check routine even when the PC 210 is operating normally, which is a PC 210 or an auxiliary PC 220 220-1 to 220-n that is worn in an abnormal manner. It is to control the execution of the.

If the authorization data exists in the storage device 211 in the PC 210 in the process (S82), the dedicated repair device 240 recognizes the unique names of the PC 210 and the auxiliary PCs 220-1 to 220-n. IDs) and the obtained recognition names are encrypted (S83).

Thereafter, the dedicated maintenance device 240 compares whether the encryption values of the recognition names match the approval data.

Accordingly, if the encryption value and the approval data match, the dedicated maintenance device 240 determines that the approval work is completed, converts to all the operation modes (S85), and ends the work.

In addition, if it is determined in step S82 that there is no approval data in the memory device 211 in the PCB 210, the dedicated maintenance device 240 determines whether a specific operation is in progress.

Accordingly, when it is determined that the specific operation is in progress, the security task is terminated.

If, in step S86, it is determined that the device is not in a specific operation, or in step S84, the encryption value and the approval data do not match, the dedicated maintenance device 240 converts the device into a specific operation mode (S87). After running the operation, the security task is terminated.

On the other hand, another embodiment of the present invention, as shown in the block diagram of Figure 9, has a separate host 260, the host 260 is provided with an information database 261, the dedicated maintenance apparatus 250 and The host 260 is configured to connect to the serial communication line 270.

The overall operation of this embodiment of the present invention is the same as the operation of the embodiment of FIG.

However, the dedicated maintenance apparatus 250 performs only a role of mediating the PC 210 and the host 260 and an authorization function, and all remaining functions exist in the host 260.

As described in detail above, the present invention has an effect of preventing illegal copying or theft by storing history information between a lead wire and a PCB and performing an approval process during repair and security operations.

In addition, the present invention has the effect of facilitating maintenance and failure diagnosis by graphically displaying the driving-related information by applying a GUI program.
