When a communication device such as a router device or the like, particularly a communication device such as a router device for a company used in an office or the like, has a malfunction in communication, the manufacturer of the communication device is analyzed for the malfunction. In order to make a request, it is necessary for the user himself to extract and acquire the log data of the communication device when the operation failure occurs.

In order to extract log data from a communication device such as a router device, the current technology is to connect a maintenance interface of both a PC (Personal Computer) for log extraction and the communication device with a wired line. It becomes necessary (see Patent Document 1). Further, when the log data extracted by the user of the communication device is insufficient due to the analysis status of the manufacturer of the communication device, it is necessary to re-extract the log data each time.

In addition, even when setting or maintaining the communication device, a UART (Universal Asynchronous) for converting, for example, a start-stop synchronization signal into serial/parallel by using a wired line between the maintenance computer and the communication device is used every time. It is necessary to connect via a maintenance interface composed of Receiver/Transmitter)-RS232C and a USB interface for USB (Universal Serial Bus) connection.

There is.

(Description of Operation of Embodiment of 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 by receiving power supply from the external power supply 50 connected to the router device 20 shown in FIG. The case will be described with reference to FIG.

When power is supplied from the external power supply 50 to the router device 20, the control unit 21, the maintenance interface 22, the USB interface 23, and the wireless LAN interface 24 provided therein operate, and the log acquisition device 10 and the USB dongle 30 are operated. Also, power is supplied from the USB interface 23 to each of them to operate. At this time, the log acquisition device 10 operates 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, and incorporates them. The battery 17 is charged.

The control of charging the battery 17 built in the log acquisition device 10 is performed by the control unit 11 and the charge/discharge control unit 16 included 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 error, for example, an alarm from the wireless LAN interface 24 due to an abnormality in wireless LAN communication will be described with reference to FIG.

When an abnormality in the wireless LAN communication (for example, inability to communicate with the wireless LAN slave terminal or inability to control the wireless LAN interface 24) occurs, the control unit 21 of the router device 20 detects 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 error 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 thereto. When the control unit 11 of the log acquisition device 10 receives the error log indicating the wireless LAN communication abnormality transmitted from the router device 20 via the UART-RS232C interface 12, the control unit 11 acquires the error log in the memory 18 and the log data 18b. Save as.

The same applies when a mobile WAN communication abnormality 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 alarm notification due to the mobile WAN communication abnormality from the USB dongle 30 from the USB interface 23 via the log acquisition device 10, the mobile WAN communication abnormality of the USB dongle 30 is detected. .. As a result, the control unit 21 transmits the USB 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 from the maintenance interface 22 as in the case of the abnormality of the wireless LAN communication. An error log indicating a mobile WAN communication error 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 error log is stored in the memory 18. It is saved as the acquisition log data 18b.

Next, the operation when the power supply from the external power supply 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 its operation, and the power supply operation from the USB interface 23 to the log acquisition device 10 and the USB dongle 30 is also stopped. In such a case, the charge/discharge control unit 16 provided inside the log acquisition device 10 immediately detects the stop of the power supply from the router device 20 in the USB interface 13, and sets the main power source of the log acquisition device 10 to the USB interface. At 13, the power source is switched from the external power source 50 supplied via the router device 20 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, the control unit 11 creates a log of power cut-off from the external power supply 50 and acquires it in the memory 18. It is saved as the 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 log of the power cut in the memory 18, and the It is also possible to use the interface 14 to transmit the log of power-off to the maintenance computer 40 by a wireless signal 104 (for example, Bluetooth).

Not only when the power supply from the external power source 50 is cut off, but also when a serious alarm related to the router device 20 occurs and the control unit 21 cannot operate normally, an error log is output to the log acquisition device 10. The same applies when an abnormality occurs in which it is not possible to send. Examples of serious alarms related to the router device 20 include abnormal heat generation of the router device 20, abnormalities of the control unit 21 of the router device 20, abnormalities of the maintenance interface 22 and the like, unauthorized access to the router device 20, and the like.

In such a case, the same state as when 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 a state similar to the case where 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 performed as in the above-described case where the power supply from the external power source 50 is cut off. 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 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 communicates with the router device 20 of the log data acquisition target. It is detected that the signal transmitted and received is abnormal, and a log indicating that a serious alarm related to the router device 20 is generated is created and stored in the memory 18 as acquired log data 18b.

Next, an 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 computer 40 is preinstalled with a maintenance application for performing maintenance management on the router device 20. 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 in the maintenance computer 40 is started, 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 so that the control unit 11 passes through the UART-RS232C interface 12 and the maintenance interface 22 of the router device 20. The maintenance data is set to be able to be transmitted/received to/from the control unit 21 of the router device 20. Then, when the control unit 21 of the router device 20 relays the setting information to be changed from the maintenance computer 40 to the control unit 11 of the log acquisition device 10, the control unit 21 of the router device 20 receives the setting information based on the setting information. Change the setting of 20.

Next, the operation of the maintenance computer 40 extracting the log data stored as the acquired log data 18b in the memory 18 of the log acquisition device 10 (that is, the operation of transferring the log data to the maintenance computer 40 side) will be described with reference to FIG. It will be explained using.

Similar to the case of changing the setting of the router device 20, the maintenance application installed in the maintenance computer 40 is started, and first, the state transitions to a state in which the control unit 11 of the log acquisition device 10 can communicate. 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 firstly stores the acquisition log data 18b in the memory 18 as the acquisition log data 18b based on the extraction request. With reference to the log data of No. 20, whether or not all the log data related to the log items necessary for diagnosing the defective portion of the router device 20 are already stored and programmed, the necessary log items are stored in the memory 18. Confirm based on the information held as the list 18a.

The control unit 11 of the log acquisition device 10 is in a state where there is a shortage of log data relating to the log items required for diagnosing the defective portion of the router device 20, and the log data relating to the necessary log items is not yet available. When the determination is made, the log data regarding the missing log item is added and acquired again from the router device 20.

Then, when the control unit 11 of the log acquisition device 10 determines that the log data related to the log items necessary for diagnosing the defective portion of the router device 20 is available, 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 by using the wireless signal 104. The maintenance computer 40 analyzes the transmitted log data to diagnose a malfunctioning part of the router device 20.

In the current technology, as described above, when the maintenance computer 40 extracts the log data relating to the router device 20, it is between the external connection terminal of 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 the log data was transferred from the router device 20. Even when 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 failure 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 provided in the maintenance computer 40 and the UART-RS232C interface 12 of the log acquisition device 10 are connected using a wired RS-232C cable, and the memory 18 of the log acquisition device 10 is connected. It is also possible to transfer the log data regarding 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 log data, the log acquisition device 10 and the maintenance computer 40 are connected using a wired cable. Work is required.

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

First, as a log item related to a communication device such as the router device 20 for which a log is to be acquired, information indicating a log item necessary for diagnosing a defective portion is programmed in advance and held in the log acquisition device 10.

That is, for example, even when the log data necessary for diagnosing a defective portion of the communication device is transmitted to the maintenance computer 40 or the manufacturer of the manufacturer of the communication device, the log data transmitted from the log acquisition device 10 is The log data necessary for diagnosing the defective portion of the communication device can be in a complete state without any excess or deficiency. Therefore, it is not necessary for an operator operating the communication device to re-acquire log data, and the maintenance staff of the communication device on the maintenance computer 40 side or an engineer on the manufacturer side of the manufacturer. Also in the above, it is possible to reduce the man-hour required for diagnosing the defective portion.

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