(Explanation of operation of the embodiment of the present invention)
Next, the operation of the log acquisition device 10 shown in FIG. 1 as an embodiment of the present invention will be described in detail with reference to the drawings.

First, the router device 20, the log acquisition device 10, and the USB dongle 30 start operating when power is supplied from the external power supply 50 connected to the router device 20 shown in FIG. 1 as an example of the communication device for which log data is to be acquired. This case will be described with reference to FIG.

When power is supplied from the external power supply 50, the router device 20 operates the control unit 21, the maintenance interface 22, the USB interface 23, and the wireless LAN interface 24, which are provided inside, and the log acquisition device 10 and the USB dongle 30. Power is also supplied from the USB interface 23 to operate each of them. At this time, the log acquisition device 10 operates and incorporates the internal control unit 11, the UART-RS232C interface 12, the USB interface 13, the wireless interface 14, the USB port 15, the charge / discharge control unit 16, and the memory 18. The battery 17 is charged.

The charging of the battery 17 built in the log acquisition device 10 is controlled by the control unit 11 and the charge / discharge control unit 16 provided in the log acquisition device 10. The charge / discharge control unit 16 is composed of a general battery charger IC (battery charge control IC) and a gas gauge IC (battery fuel gauge IC).

Next, the operation when the control unit 21 of the router device 20 detects an alarm from the wireless LAN interface 24 due to some error, for example, an abnormality in the wireless LAN communication, will be described with reference to FIG.

When an abnormality in the wireless LAN communication (for example, communication failure with the wireless LAN slave unit terminal or controllessness of the wireless LAN interface 24) occurs, the control unit 21 of the router device 20 causes the abnormality of the wireless LAN interface 24. Detect. As a result, the control unit 21 transmits an error log indicating a wireless LAN communication abnormality from the maintenance interface 22 to the log acquisition device 10 connected via the RS232C cable 102 or the log acquisition device 10 directly connected to the log acquisition device 10. When the control unit 11 of the log acquisition device 10 receives the error log indicating the wireless LAN communication error transmitted from the router device 20 via the UART-RS232C interface 12, the control unit 11 acquires the error log in the memory 18. Log data 18b Save as.

The same applies when a mobile WAN communication error occurs in the USB dongle 30. In such a case, the control unit 21 of the router device 20 receives the notification of the mobile WAN communication abnormality in the USB dongle 30 from the USB interface 23.

When the control unit 21 of the router device 20 receives the notification of the alarm due to the mobile WAN communication abnormality from the USB dongle 30 from the USB interface 23 via the log acquisition device 10, it detects the mobile WAN communication abnormality of the USB dongle 30. .. As a result, the control unit 21 connects the maintenance interface 22 to the log acquisition device 10 connected via the RS232C cable 102 or the log acquisition device 10 directly connected to the log acquisition device 10 as in the case of the wireless LAN communication error. An error log indicating an abnormality in the mobile WAN communication of the dongle 30 is transmitted. When the control unit 11 of the log acquisition device 10 receives the error log indicating the mobile WAN communication abnormality of the USB dongle 30 transmitted from the router device 20 via the UART-RS232C interface 12, the control unit 11 stores the error log in the memory 18. Save as acquired log data 18b.

Next, the operation when the power supply from the external power source 50 to the router device 20 is stopped due to a power failure or the like will be described with reference to FIG.

When the power supply from the external power supply 50 is stopped, the router device 20 stops the operation, and the power supply operation to the log acquisition device 10 and the USB dongle 30 from the USB interface 23 is also stopped. In such a case, the charge / discharge control unit 16 provided inside the log acquisition device 10 immediately detects that the power supply from the router device 20 in the USB interface 13 has stopped, and uses the main power supply of the log acquisition device 10 as the USB interface. In 13, the power source supplied from the external power source 50 supplied via the router device 20 is switched to the power source supplied from the built-in battery 17. When the control unit 11 of the log acquisition device 10 detects that the main power supply has been switched from the power supply by the external power supply 50 to the power supply by the battery 17, it creates a log of power failure from the external power supply 50 and acquires it in the memory 18. Save as log data 18b.

At this time, even if the power supply from the external power supply 50 is cut off, if the remaining voltage of the battery 17 is sufficient, it is possible to save the power failure log in the memory 18 and wirelessly. It is also possible to use the interface 14 to transmit the power failure log to the maintenance computer 40 by a wireless signal 104 (for example, Bluetooth).

Further, not only when the power supply from the external power supply 50 is cut off, a serious alarm related to the router device 20 occurs and the control unit 21 cannot operate normally, so that an error log is sent to the log acquisition device 10. The same applies when an abnormality occurs that prevents the transmission of. Examples of serious alarms related to the router device 20 include abnormal heat generation of the router device 20, an abnormality of the control unit 21 of the router device 20, an abnormality of the maintenance interface 22, and the like, and unauthorized access to the router device 20.

In such a case, the power supply operation from the external power source 50 is stopped, or the signal transmission / reception operation with the log acquisition device 10 is abnormal. When the power supply operation from the external power source 50 to the log acquisition device 10 is stopped, the charge / discharge control unit of the router device 20 is in the same state as in the above-mentioned case where the power is cut off from the external power source 50. 16 detects a power failure of the external power source 50, switches the main power source to the internal battery 17, and the control unit 11 creates a log of the power failure from the external power source 50 and acquires the log data 18b in the memory 18. Save as.

Further, when the signal transmission / reception operation between the router device 20 and the log acquisition device 10 falls into an abnormal state, the control unit 11 of the log acquisition device 10 is connected to the router device 20 for which the log data is acquired. Detects that the signal transmitted / received in the above is abnormal, creates a log indicating that a serious alarm related to the router device 20 has occurred, and saves it in the memory 18 as acquired log data 18b.

Next, the operation when the setting of the router device 20 is changed by wireless communication from the maintenance computer 40 via the log acquisition device 10 will be described with reference to FIG. It is assumed that the maintenance application for performing maintenance management related to the router device 20 is pre-installed on the maintenance computer 40. Here, the maintenance application is provided in advance from the manufacturer of the router device 20 to be maintained to the administrator of the maintenance computer 40.

When the maintenance application installed on the maintenance computer 40 is started, for example, when a Bluetooth signal is used as the wireless signal 104, pairing is performed by wireless communication with the wireless interface 14 of the log acquisition device 10. As a result, the maintenance computer 40 shifts to a state in which it can communicate with the control unit 11 of the log acquisition device 10.

Then, the maintenance computer 40 communicates with the control unit 11 of the log acquisition device 10 to communicate with the control unit 11 via the UART-RS232C interface 12 and the maintenance interface 22 of the router device 20. It is set to a state in which maintenance data can be transmitted / received to / from the control unit 21 of the router device 20. After that, when the setting information to be changed is transmitted from the maintenance computer 40 via the control unit 11 of the log acquisition device 10, the control unit 21 of the router device 20 relays the setting information to be changed, and the router device 21 is based on the setting information. Change the setting of 20.

Next, FIG. 1 shows an operation in which the maintenance computer 40 extracts the log data saved as the acquisition log data 18b in the memory 18 of the log acquisition device 10 (that is, an operation in which the log data is transferred to the maintenance computer 40 side). It will be described using.

Similar to the case of changing the setting of the router device 20, the maintenance application installed on the maintenance computer 40 is started, and first, the state shifts to a state in which communication with the control unit 11 of the log acquisition device 10 is possible. After that, the maintenance application of the maintenance computer 40 transmits a log data extraction request to the control unit 11 of the log acquisition device 10. When the log data extraction request is transmitted from the maintenance computer 40, the control unit 11 of the log acquisition device 10 first stores the log data as the acquisition log data 18b in the memory 18 based on the extraction request. With reference to the log data of 20, it is programmed and required in the memory 18 whether or not all the log data related to the log items required for diagnosing the defective part of the router device 20 are stored. Confirm based on the information held as list 18a.

The control unit 11 of the log acquisition device 10 is in a state where the log data related to the log items required for diagnosing the defective part of the router device 20 is insufficient and the log data related to the required log items are not yet available. If it is determined, the log data related to the missing log items is added from the router device 20 and acquired again.

Then, when the control unit 11 of the log acquisition device 10 determines that the log data related to the log items required for diagnosing the defective portion of the router device 20 are available, the control unit 11 is based on the extraction request from the maintenance computer 40. Then, the log data of the router device 20 stored as the acquired log data 18b in the memory 18 is extracted and transmitted to the requesting maintenance computer 40 using the wireless signal 104. The maintenance computer 40 diagnoses the malfunction portion of the router device 20 by analyzing the transmitted log data.

In the current technology, as described above, when the maintenance computer 40 extracts the log data related to the router device 20, it is between the external connection terminal provided by the maintenance computer 40 and the maintenance interface 22 of the router device 20. Was connected using a wired cable such as an RS-232C cable, and log data was transferred from the router device 20. Even in the case where the log data of the router device 20 stored as the acquired log data 18b in the memory 18 of the log acquisition device 10 is transmitted to the maintenance computer 40 by using the wireless signal 104 as in the present embodiment. For example, when a problem occurs in the wireless connection with the wireless interface 14, it is possible to use the same log data extraction procedure as in the case of the current technology.

That is, the external connection terminal included in the maintenance computer 40 and the UART-RS232C interface 12 of the log acquisition device 10 are connected by using a wired RS232C cable, and the memory 18 of the log acquisition device 10 is used. It is also possible to transfer the log data related to the router device 20. However, in such a case, as in the case of the current technology, each time the maintenance computer 40 tries to extract the log data, the log acquisition device 10 and the maintenance computer 40 are connected by using a wired cable. Work is required.

(Explanation of the effect of this embodiment)
As described in detail above, the following effects can be achieved in the present embodiment.

First, as log items related to communication devices such as the router device 20 for which logs are to be acquired, information indicating log items required for diagnosing defective parts is programmed in advance and stored in the log acquisition device 10. Therefore, in the log data analysis stage, it is possible to eliminate the trouble of re-acquiring the log data due to insufficient log items, and it is possible to improve the ease of maintenance of the communication device.

That is, for example, even when the log data required for diagnosing a defective part of the communication device is transmitted to the maintenance computer 40 or the manufacturer of the communication device, the log data transmitted from the log acquisition device 10 is transmitted. , The log data required for diagnosing the defective part of the communication device can be prepared in just proportion. Therefore, it is not necessary for the operator who operates the communication device to reacquire the log data, and the maintenance staff of the communication device on the maintenance computer 40 side or the engineer on the manufacturer's side of the manufacturer. In this case as well, the man-hours required for diagnosing the defective part can be reduced.

Second, the maintenance computer 40 that extracts and analyzes log data related to communication devices such as the router device 20 and changes the settings of the communication device is a log to be extracted by wireless communication with the log acquisition device 10. It is possible to transfer data to diagnose a defective part of the communication device, or to perform maintenance such as changing the setting of the communication device. Therefore, it is not necessary to manually connect the log acquisition device 10 and the maintenance computer 40 with a cable each time, and the convenience of the maintenance person of the communication device can be improved.

Thirdly, since the log data related to the communication device such as the router device 20 to be log acquisition is saved as the acquisition log data 18b by the memory 18 in the log acquisition device 10, the communication of the router device 20 or the like to be log acquisition is performed. The device does not need to have a memory for storing log data.

Fourth, as the interface to be provided by the communication device such as the router device 20 to be logged, the interface provided by the current communication device such as the router device can be used as it is.
