Description

[Technical Field]

[0001] The present disclosure relates to an information collection device and an information collection method. [Background technology]

[0002] SNMP (Simple Network Management Protocol) is known as the standard protocol for network management in Internet environments. SNMP-compatible network management systems acquire MIB (Management Information Base) information held by agents, which are SNMP-compatible devices, and upload (transport) it to a manager server. MIB information includes the agent's system information (device operation information, etc.), interface information (communication quality such as the number of sent and received packets and the number of errors), and IP information (routing table information for IP devices, etc.), and the manager server can manage network devices by collecting this MIB information.

[0003] For example, Patent Document 1 discloses an example of an information collection method using SNMP network management technology. This document describes a network management information collection method using SNMP, a protocol for monitoring network devices, in which, for an SNMP-compatible device whose connection has been cut off, device information during the downtime is stored within the device, and after the connection is restored, a manager server retrieves the information, including the information during the downtime.

[0010] [Figure 1] 1 is an overall configuration diagram of an information communication system according to an embodiment; [Figure 2] FIG. 2 is a block diagram showing the configuration of the information collection device of FIG. [Figure 3] 3 is a flowchart of an information collection method performed by the information collection device of FIG. 2. [Figure 4] 3A to 3C are diagrams showing some examples of SNMP non-compliant device information included in the upload data created by the upload data creation unit of FIG. 2. DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, several embodiments of the present invention will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of components described as embodiments or shown in the drawings are merely illustrative examples and are not intended to limit the scope of the present invention.

[0012] 1 is a diagram showing the overall configuration of an information communication system 1 according to an embodiment. The information communication system 1 includes an SNMP non-compliant device 2, an information collection device 4, and an SNMP manager server 6.

[0013] The non-SNMP-compliant device 2 is a network device that does not support SNMP. In this embodiment, an example of the non-SNMP-compliant device 2 is a wireless module connected to multiple sensor devices 8 via a wireless communication network 9. The multiple sensor devices 8 are, for example, devices for detecting physical parameters related to the operating states of various devices (not shown) in plant facilities, and the non-SNMP-compliant device 2 (wireless module) is configured to collect detected values ​​of each sensor device via wireless communication. While FIG. 1 illustrates a case in which multiple sensor devices 8 are connected to one non-SNMP-compliant device 2 (wireless module), the number of sensor devices 8 connected to the wireless module may be one.

[0014] The information collection device 4 is a device for collecting various data (including SNMP non-compliant device information 10 described below) from the SNMP non-compliant device 2. The information collection device 4 is connected to the SNMP non-compliant device 2, which is a network device that does not support SNMP, via, for example, serial communication 7. Furthermore, the connection of the non-SNMP compatible device 2 to the information collection device 4 is not limited to a mode in which information can be sent and received between these devices, and for example, in addition to the above-mentioned serial communication 7, various communication methods in accordance with the TCP / IP protocol can be used.

[0015] The information collection device 4 is also an SNMP-compatible network device, and is connected to an SNMP manager server 6 via a communication network 5. The information collection device 4 includes various data collected from the non-SNMP-compatible device 2 in upload data, which is MIB information, and sends the data to the SNMP manager server 6. By receiving the upload data from the information collection device 4, the SNMP manager server 6 obtains information about the non-SNMP-compatible device 2 contained in the upload data. This enables the SNMP manager server 6 to manage the non-SNMP-compatible device 2.

[0016] Next, a detailed description will be given of the configuration of the information collection device 4 and the information collection method performed by the information collection device 4. Fig. 2 is a block diagram showing the configuration of the information collection device 4 in Fig. 1, and Fig. 3 is a flowchart of the information collection method performed by the information collection device 4 in Fig. 2.

[0017] The information collection device 4 is composed of, for example, a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), and a computer-readable storage medium. A series of processes for realizing various functions is stored in a storage medium, for example, in the form of a program. The CPU reads this program into RAM and executes information processing and arithmetic operations to realize various functions. The program may be pre-installed in a ROM or other storage medium, provided in a state stored in a computer-readable storage medium, or distributed via wired or wireless communication means. Examples of computer-readable storage media include magnetic disks, magneto-optical disks, CD-ROMs, DVD-ROMs, and semiconductor memories.

[0018] 2, the information collection device 4 includes an SNMP non-compliant device information acquisition unit 12, an upload data creation unit 14, and an upload data transmission unit 16. The SNMP non-compliant device information acquisition unit 12 is configured to acquire SNMP non-compliant device information 10 by communicating with the SNMP non-compliant device 2. The upload data creation unit 14 is configured to create upload data 11 by assigning the SNMP non-compliant device information 10 to a unique MIB area defined in the MIB information by the SNMP protocol. The upload data transmission unit 16 is configured to transmit the upload data 11 to the manager server 6.

[0019] The SNMP non-compliant device information 10 includes at least information related to the SNMP non-compliant device 2. The SNMP non-compliant device information 10 includes, for example, network information, operation information, and communication quality of the SNMP non-compliant device 2. In this embodiment, the SNMP non-compliant device information 10 includes evaluation items (e.g., RSSI, number of received packets, number of error packets, etc.) related to the wireless communication network 9 (physical layer) between the SNMP non-compliant device 2 and the plurality of sensor devices 8, and parameters related to the state of the SNMP non-compliant device 2 (e.g., temperature of a board included in the SNMP non-compliant device 2, remaining battery voltage, etc.).

[0020] When the information collecting method is performed by the information collecting device 4, first the SNMP non-compliant device information acquiring unit 12 acquires the SNMP non-compliant device information 10 from the SNMP non-compliant device 2 (step S1). Because the SNMP non-compliant device 2 is a network device that does not support SNMP, the information collecting device 4 acquires the SNMP non-compliant device information 10 via the above-mentioned serial communication 7. As described above, the SNMP non-compliant device information 10 includes the network information, operation information, communication quality, etc. of the SNMP non-compliant device 2.

[0021] Next, the upload data creation unit 14 creates the upload data 11 by adding the SNMP non-compliant device information to the unique MIB area defined in the MIB information by the SNMP protocol (step S2).

[0022] Fig. 4 is a diagram showing some examples of non-SNMP-compliant device information included in the upload data 11 created by the upload data creation unit 14 in Fig. 2. Fig. 4 shows some examples of the non-SNMP-compliant device information, such as the MAC address and IP address of another sensor device 8 connected to the non-SNMP-compliant device 2, the temperature and voltage of the coin-type battery (the battery is not limited to being coin-type) built into the sensor device 8, the number of packets sent from the non-SNMP-compliant device 2 to the sensor device 8, the number of packets received from the sensor device 8 of the non-SNMP-compliant device 2, the number of error packets received from the sensor device 8 of the non-SNMP-compliant device 2, and the connection status between the non-SNMP-compliant device 2 and the sensor device 8.

[0023] Next, the upload data transmitter 16 transmits the upload data 11 created in step S2 to the SNMP manager server 6 (step S3). This allows the information acquired from the non-SNMP-compliant device 2 by the information collecting device 4 to be uploaded to the SNMP manager server 6, enabling the SNMP manager server 6 to manage the non-SNMP-compliant device 2.

[0024] In another embodiment, the non-SNMP-compliant device information 10 added to the unique MIB area of ​​the upload data 11 may include detection values ​​of multiple sensor devices 8 connected to the non-SNMP-compliant device 2. In this case, the detection values ​​of the multiple sensor devices 8 are included in the non-SNMP-compliant device information 10 and added to the unique MIB area, so that the detection values ​​can be uploaded to the SNMP manager server 6. Therefore, the SNMP manager server 6 can grasp the operating status of various devices in the plant equipment in which the multiple sensor devices 8 are installed, based on the detection values ​​of the multiple sensor devices 8 added to the unique MIB area of ​​the received upload data 11, and can remotely manage abnormality monitoring, diagnosis, and the like.

[0025] In another embodiment, the non-SNMP-compliant device information 10 added to the unique MIB area of ​​the upload data 11 may include information about a plurality of sensor devices 8 that are lower-level devices connected to the non-SNMP-compliant device 2. In this case, the upload data 11 to be uploaded to the SNMP manager server 6 is configured by adding information about the plurality of sensor devices 8 to the unique MIB area in addition to information about the non-SNMP-compliant device 2. This allows the SNMP manager server 6 to manage not only the non-SNMP-compliant devices but also the plurality of sensor devices 8 that are lower-level devices connected to the non-SNMP-compliant devices.

[0026] As described above, according to each of the above-mentioned embodiments, the upload data uploaded to an SNMP manager server, which is an SNMP-compatible device, is configured by adding non-SNMP-compatible device information acquired from a non-SNMP-compatible device to a unique MIB area defined in the MIB information. This allows information acquired from a non-SNMP-compatible device to be uploaded to the SNMP manager server, making it possible for the SNMP manager server to manage the non-SNMP-compatible device.

[0027] In addition, within the scope of the present disclosure, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described embodiments may be combined as appropriate.

This allows information acquired from the non-SNMP-compliant device to be uploaded to the SNMP manager server, making it possible for the SNMP manager server to monitor the non-SNMP-compliant device. Furthermore, because the non-SNMP-compliant device information acquired from the non-SNMP-compliant device can be uploaded by the SNMP manager as MIB information, the non-SNMP-compliant device can be centrally managed by the SNMP manager in the same way as other network devices, thereby effectively reducing management costs.

This allows the SNMP manager server to monitor not only the non-SNMP-compliant device but also the lower-level devices connected to the non-SNMP-compliant device. As a result, the information about the lower-level devices connected to the non-SNMP-compliant device can be uploaded by the SNMP manager as MIB information along with the non-SNMP-compliant device information, so that the lower-level devices connected to the non-SNMP-compliant device can also be centrally managed by the SNMP manager in the same way as other network devices, thereby effectively reducing management costs.
