Description

The present invention relates to a communication system, a communication device, a communication port connection state confirmation method, and a communication port connection state confirmation program.

In a communication device, when confirming whether or not there is an abnormality in the communication port used by the user, a specific user who is familiar with the communication device normally performs specific settings prepared in advance for the communication device. You can check the status of the target communication port by accessing the screen, or connect the target communication port as described in Japanese Unexamined Patent Application Publication No. 2017-139542 "Communication Device" of Patent Document 1. A display such as a light emitting diode (LED) for confirming a specific state such as the presence or absence of a device is visually checked.

However, currently, in most cases, a specific user sets the communication device, and other users do not know how to check the status of the communication device or access the setting screen of the communication device. I have been unable to do so.

In other words, in order to access the setting screen of the communication device, the user is required to enter in advance a URL (Uniform Resource Locator) for connection to the communication device, a password for access, or the like. In the case of a communication device having a communication port, it is necessary to identify the target communication port. It was difficult to confirm whether or not

In addition, even if it is possible to confirm whether or not there is an abnormality in the target communication port only by displaying a specific state confirmation such as a light emitting diode (LED) regarding the connection status of the target communication port, the cause of the abnormality cannot be determined. In most cases it cannot be specified.

JP 2017-139542 A

As described above, in the current technology related to the present invention, when trying to check whether there is an abnormality in the communication port of the communication device that the user is using, the setting screen prepared in advance is accessed. Alternatively, a light-emitting diode (LED) display indicating a particular state, such as the connection state of a communication port, was visually checked. Therefore, the current technology has the following problems to be solved.

First, information such as the setting screen of the communication device (screen information that displays information indicating the connection state of the communication port) can be accessed only by some specific administrators of the communication device. Only the user, other normal users cannot check the status of the communication port being used.

Secondly, in order to access the setting screen of the communication device, it is necessary to enter the URL for connection to the communication device, the password for access, etc., but other ordinary users than some specific users users usually do not know the URL for connection or the password for access in advance.

Thirdly, when a communication device has a plurality of communication ports, the name given to each communication port is generally used to manage the communication device. Even if normal users other than some specific users are able to access the setting screen of the communication device, they do not have knowledge of the name given to the target communication port for which they want to know the connection state. , it is difficult to determine the state of the target communication port.

Fourthly, by installing a light-emitting diode (LED) indicating a specific state related to the connection state of the communication port in the communication device, even if the user visually confirms the display of the light-emitting diode (LED), There is a limit to what can be displayed by a diode (LED), and it is not possible to confirm what kind of abnormal state has occurred in the communication port.

(Explanation of operation example of embodiment of the present invention)
Next, the operation of the communication system 100 shown in FIG. 2 as an example of the communication system according to the present invention will be described in detail with reference to the drawings.

FIG. 3 is a flowchart for explaining an example of the operation of the communication system 100 shown in FIG. 2 as an example of the communication system according to the present invention. An operation example when checking the connection state of the port 2A is described. Here, FIG. 3A shows an example of the operation of the mobile terminal 30 that configures the communication system 100, and FIG. 3B shows an example of the operation of the communication device 20 that configures the communication system 100. .

Before explaining the operation shown in the flowchart of FIG. 3, the assumptions thereof will be explained first. As a first premise, it is assumed that the communication device 20 is installed near the user carrying the mobile terminal 30 . Therefore, the user uses the code reading unit 32 of the portable terminal 30 to display communication port codes corresponding to the vicinity of each of the communication A port 2A, the communication B port 2B, etc. of the communication device 20. It is assumed that the display contents (code information such as QR code, bar code, etc.) of the communication A port code display section 3A, the communication B port code display section 3B, and so on can be read. Also, it is assumed that the communication device 20 and the mobile terminal 30 are wirelessly connected using a wireless LAN as the wireless network 41 .

As the next premise, the code information displayed as the communication port code by the communication A port code display unit 3A, the communication B port code display unit 3B, etc. of the communication device 20 in FIG. Assuming the case. As shown in FIG. 4, the QR code contains not only information indicating the location where the detailed connection status of the corresponding communication port is stored, but also the mobile terminal 30 as a wireless network 41 using a wireless LAN. In order to enable wireless connection to the communication device 20, a case is shown in which the network name (SSID: Service Set Identifier) conforming to the IEEE 802.11 standard for the communication device 20 and encryption key information are also stored. ing.

FIG. 4 is a table showing an example of information stored in a QR code displayed as a communication A port code by the communication A port code display unit 3A in the communication device 20 shown in FIG. FIG. 4 assumes that the user of the portable terminal 30 is trying to grasp the connection state of the communication A port 2A of the communication device 20, and the communication A port code display section 3A is displayed as the communication A port code information. An example of information displayed in a QR code is shown.

As shown in FIG. 4, the information stored in the QR code as the communication A port code is a URL (Uniform Resources Locator) where information indicating the operating state (connection state) of the communication A port 2A is stored. In addition to the communication A port operation confirmation URL 53 indicating the network name (SSID) specified in the IEEE 802.11 standard as information required when connecting to the communication device 20 via the wireless LAN of the wireless network 41 51 and an encryption key 52 . Here, FIG. 4 shows a case where the communication A port operation confirmation URL 53 is, for example, 'http://aaa.aaa.aaa\tushinA' indicating a specific location within the communication device 20. The network name (SSID) 51 is 'AAAAAAA-0020' and the encryption key 52 is 'aaaaaaaaaaaaa'. That is, 'http://aaa.aaa.aaa\tushinA' indicated by the communication A port operation confirmation URL 53 is a storage location (page address).

As a further premise, detailed information on the current connection status of the communication A port 2A and the communication B port 2B of the communication device 20 in FIG. Although it is stored in the locations indicated by the communication B port operation confirmation URLs (not shown), it is assumed that they are in the connected state shown in FIG. FIG. 5 is a table showing an example of the connection state of the communication A port 2A and the communication B port 2B in the communication device 20 shown in FIG. 2, and stores information showing the detailed connection state of each communication port. .

As shown in a state 61 in FIG. 5, the connection state of the communication A port 2A is set to stop operation regardless of whether or not it is connected to the opposite communication device 40A. be. On the other hand, the connection state of the communication B port 2B indicates a state of being connected to the opposite communication device 40B via the interface 21B and an operable state. Therefore, even if the user connects the opposite communication device 40A via the interface 21A to the communication A port 2A set to stop operation, communication cannot be performed. On the other hand, the communication B port 2B in the connected state is in a state of communicating with the opposite communication device 40B, and the communication state with the opposite communication device 40B is Speed (communication speed) 62, Duplex mode. 63, data communication 64, .

Taking the above assumptions into consideration, the flow chart of FIG. 3 will be described below. First, in FIG. 3A, the user of the mobile terminal 30 activates an application for checking the connection state of the communication A port 2A of the communication device 20 (step S31). Then, the display contents (that is, the code information) of the communication A port code display section 3A displayed as the communication port code information near the communication A port 2A of the communication device 20 are read by the code reading section 32 of the portable terminal 30. Read (step S32). Thereafter, mobile terminal 30 displays network name (SSID) 51, encryption key 52, and communication A port operation confirmation as shown in FIG. It is confirmed that each of the information 'AAAAAAAAA-0020', 'aaaaaaaaaaaaa', and 'http://aaa.aaa.aaa\tushinA' is included as the URL 53 for use (step S33).

After confirming the code information, the portable terminal 30 activates the wireless communication unit 31, reads 'AAAAAAAA-0020' for the network name (SSID) 51 read by the code reading unit 32, and reads 'aaaaaaaaaaa' for the encryption key 52. is used to issue a wireless connection request to the communication device 20 via the wireless network 41, that is, the wireless LAN (step S34).

When the wireless communication unit 4 of the communication device 20 receives the wireless connection request from the mobile terminal 30, the control unit 1 controls the wireless connection included in the wireless connection request as shown in FIG. It is checked whether 'AAAAAAA-0020' of the network name (SSID) 51 is a wireless connection request for its own communication device 20. If it is not a wireless connection request for its own communication device 20, the received wireless Drop the connection request.

On the other hand, if the wireless connection request from the mobile terminal 30 is a wireless connection request to its own communication device 20, then the encryption key 52 'aaaaaaaaaaaa' included in the wireless connection request is 20, and confirms whether or not it matches the encryption key registered in advance as key information for authentication. Discard the received wireless connection request. Also, if the 'aaaaaaaaaaaaa' of the encryption key 52 included in the wireless connection request matches the pre-registered encryption key, the connection partner is authenticated and wireless connection with the mobile terminal 30 is established. and returns a response signal to the portable terminal 30 that made the request (step S21).

The mobile terminal 30 checks whether or not the wireless connection with the communication device 20 has succeeded by monitoring whether or not a response signal has been received from the communication device 20 (step S35). If the wireless connection with the communication device 20 fails (No in step S35), the portable terminal 30 displays on the display unit 33 that the wireless connection with the communication device 20 was not possible, and the communication device 20 The user is notified that the connection status of the communication A port 2A cannot be confirmed (step S36).

On the other hand, when the wireless connection with the communication device 20 is successful (Yes in step S35), the mobile terminal 30 reads the communication A port operation confirmation URL 53 read by the code reading unit 32 via the wireless network 41. request the communication device 20 to access 'http://aaa.aaa.aaa\tushinA' and obtain detailed information on the connection status of the communication A port 2A of the communication device 20 (Step S37).

When the acquisition request from the mobile terminal 30 is received by the wireless communication unit 4 , the communication device 20 , under the control of the control unit 1 , checks the communication A port operation confirmation URL 53 'http://aaa' included in the acquisition request. The connection status of the communication A port 2A is confirmed by accessing .aaa.aaa\tushinA' and obtaining detailed information on the connection status of the communication A port 2A (step S22). Here, at the location (page address) indicated by 'http://aaa.aaa.aaa\tushinA' of the communication A port operation confirmation URL 53, as shown in the state 61 of FIG. Information is set to the effect that the communication A port 2A is in the state of being set to stop operation. Thereafter, the communication device 20 returns the confirmed information regarding the connection state of the communication A port 2A to the portable terminal 30 that requested the acquisition via the wireless network 41 (step S23).

When the mobile terminal 30 receives the detailed information about the connection state of the communication A port 2A requested for acquisition from the communication device 20, the mobile terminal 30 displays the received detailed information about the connection state of the communication A port on the display unit 33. The user of the terminal 30 is notified (step S38). 5, the communication A port 2A of the communication device 20 is set to stop operation, and communication with the opposite communication device 40A is stopped. The user of the mobile terminal 30 is notified that the mobile terminal 30 is in this state.

Therefore, even if the communication A port 2A of the communication device 20 is in an inoperative state and the opposite communication device 40A is connected to the communication A port 2A, the user of the portable terminal 30 can still connect the communication device 20 and the opposite communication device. It is possible to easily grasp that it is in a state where communication with 40A cannot be performed. Therefore, when the user wants to use the communication A port 2A to communicate with the opposite communication device 40A, the communication A port 2A on the communication device 20 side must be changed to an operable state. Either perform the setting operation, or ask an administrator who has specialized knowledge of the communication device 20 to change the communication A port 2A on the communication device 20 side to an operable state and set it. I understand.

In the above description of FIG. 3, the information for confirming the connection state dedicated to the communication A port 2A, that is, the detailed information regarding the connection state of the communication A port exists in the information storage unit within the communication device 20. However, it is not limited to such cases. For example, information for confirming the connection state dedicated to the communication A port 2A, that is, detailed information regarding the connection state of the communication A port may be stored in a data storage device separate from the communication device 20. FIG. In such a case, the mobile terminal 30 can directly access the communication A port operation confirmation URL 53 'http://aaa.aaa.aaa\tushinA' in the data storage device (wireless LAN, public line network, Internet means to access 'http://aaa.aaa.aaa\tushinA' via the communication device 20, and the data storage device directly without going through the communication device 20 detailed information on the connection state of the communication A port 2A can be obtained from the URL 53 for checking the operation of the communication A port 'http://aaa.aaa.aaa\tushinA'.

In addition, when each communication port such as the communication A port 2A, the communication B port 2B, etc. of the communication device 20 is composed of a wired communication port to which a wired communication line is connected as the interface 21A, the interface 21B, . is shown, but it is not limited to this case. For example, each communication port such as the communication A port 2A, the communication B port 2B, . Alternatively, a wired communication line may be connected to one or more communication ports, and a wireless communication line may be connected to the remaining communication ports (two or more communication ports).

In a configuration in which a wireless communication line is connected to all or part of each communication port, for example, a specific communication port whose connection state is to be checked using the portable terminal 30 carried by the user is connected to the wireless communication line. is connected to the communication port, the communication port to which a wireless communication line different from the specific communication port is connected is used to wirelessly connect to the mobile terminal 30, and the wireless communication whose connection state is to be confirmed You can check the status of a specific communication port for

(Other embodiments)
In the embodiment described above, the case where the communication device 20 having the communication A port 2A whose connection state is to be checked exists near the user carrying the mobile terminal 30 has been described. In this embodiment, the communication device 20 having the communication A port 2A whose connection state is to be checked is installed in a remote location that is difficult for the user to directly access. to explain. First, with reference to FIG. 6, a system configuration example according to another embodiment will be described. FIG. 6 is a system configuration diagram showing an example different from FIG. 2 of the system configuration of the communication system according to the present invention.

In the communication system 100A of FIG. 6, the mobile terminal 30 carried by the user and the communication device 20 are located apart from each other. 41 (for example, wireless LAN), wireless communication is performed via a wireless network 41A comprising a public line network such as LTE (Long Term Evolution) or Wi-MAX (Worldwide Interoperability for Microwave Access), the Internet, or the like. Therefore, instead of the wireless communication units 31 and 4, the mobile terminal 30 and the communication device 20 are provided with a wireless communication unit 31A that can be wirelessly connected via the wireless network 41A. A part 4A is provided.

Then, the code displayed as the communication A port code by the communication port code display section 3A for the communication A port 2A, for example, the communication port code display section 3A for the communication A port 2A of the communication device 20 for which the user wants to check the connection state. The information is displayed not only in the vicinity of the communication A port 2A of the communication device 20 as described above in FIG. . Therefore, the user can use the code reading unit 32 of the portable terminal 30 to directly read the communication A port code 3A1 displayed in the user's home 70 .

The communication A port code 3A1 displayed in the user's home 70 is code information displayed as the communication A port code near the communication A port 2A of the communication device 20 by the communication A port code display unit 3A. By transferring from the communication device 20 to the user's house 70 side via a wireless communication line or a wired communication line, it may be displayed in the user's house 70, and may be displayed in the vicinity of the communication A port 2A as a communication A port code. The displayed code information may be read manually using an arbitrary code reading function and transmitted to the user's home 70 to be displayed in the user's home 70 .

Also, in the case of a system configuration like the communication system 100A in FIG. (SSID) and encryption key information need not be displayed in the communication A port code 3A1. Therefore, unlike the case of FIG. 4 in the above-described embodiment, the communication A port code 3A1 includes, as code information, the connection of the specific communication A port 2A for which the user carrying the portable terminal 30 wants to know the connection state. It suffices to display only the information related to the communication A port operation confirmation URL indicating the location where detailed information about the state is stored.

Next, an operation example of the communication system 100A shown in FIG. 6 as another embodiment will be described with reference to FIG. FIG. 7 is a flow chart for explaining an example of the operation of the communication system 100A shown in FIG. Here, FIG. 7A shows an example of the operation of the mobile terminal 30 that configures the communication system 100A, and FIG. 7B shows an example of the operation of the communication device 20 that configures the communication system 100A. .

Note that in the flowchart of FIG. 7, the mobile terminal 30 and the communication device 20 are wirelessly connected not via a wireless LAN but via a public line network or the Internet as the wireless network 41A. 3, the connection processing steps for wireless LAN connection, that is, the steps S33, S34, S35 and S21 in FIG. 3 are unnecessary and are omitted from FIG. Further, each step shown in the flow chart of FIG. 7 performs substantially the same operation as each step other than steps S33, S34, S35 and S21 of FIG. there is

First, in FIG. 7A, the user of the mobile terminal 30 activates an application for checking the connection state of the communication A port 2A of the communication device 20 (step S31). Then, the code reading unit 32 of the portable terminal 30 reads the communication A port code 3A1 (code information) displayed at the user's home 70 (step S32). After that, the portable terminal 30 reads the communication A port code 3A1 (code information), which indicates the location where the information indicating the connection state regarding the communication A port 2A of the communication device 20 is stored. It is confirmed that the information 'http://aaa.aaa.aaa\tushinA' as shown in FIG. 4 is set as the URL (step S33). Here, 'http://aaa.aaa.aaa\tushinA' displayed as the communication A port operation confirmation URL is information indicating a specific location within the communication device 20, as in the case of the above-described embodiment. be.

After confirming the communication A port code 3A1 (code information), the mobile terminal 30 activates the wireless communication unit 31A for wireless communication with the communication device 20 via the wireless network 41A including the public line network and the Internet. After activation, access is made to the communication A port operation confirmation URL 'http://aaa.aaa.aaa\tushinA' read by the code reader 32 via the wireless network 41A. The communication device 20 is requested to obtain detailed information about the connection state of the communication A port 2A (step S37).

When the communication device 20 receives an acquisition request from the mobile terminal 30 at the wireless communication unit 4A that performs wireless communication with the mobile terminal 30 via a wireless network 41A including a public line network and the Internet, , under the control of the control unit 1, the communication A port operation confirmation URL 'http://aaa.aaa.aaa\tushinA' included in the acquisition request is accessed, and the communication A port 2A is accessed. By acquiring detailed information on the connection state of the communication A port 2A, the connection state of the communication A port 2A is confirmed (step S22). Here, at the location (page address) of 'http://aaa.aaa.aaa\tushinA' of the communication A port operation confirmation URL 53, for example, as shown in the state 61 of FIG. Information is set to the effect that the communication A port 2A in 20 is in a state of being set to stop operation. After that, the communication device 20 returns the confirmed detailed information regarding the connection state of the communication A port 2A to the mobile terminal 30 that requested the acquisition via the wireless network 41A (step S23).

When the mobile terminal 30 receives the detailed information about the connection state of the communication A port requested for acquisition from the communication device 20, the mobile terminal 30 displays the received detailed information about the connection state of the communication A port on the display unit 33. 30 users are notified (step S38). That is, in the state 61 of FIG. 5, the communication A port 2A of the communication device 20 is in the state of being set to stop operation, and communication with the opposite communication device 40A is stopped. The user of the mobile terminal 30 is notified that the mobile terminal 30 is in this state.

Therefore, even if the user of the mobile terminal 30 is in a remote location where it is impossible to access the communication device 20, the communication A port 2A can operate as in the case of the above-described embodiment. It can be easily grasped that it is in a stopped state. Therefore, when the user wants to communicate with the opposite communication device 40A using the communication A port 2A in the operation stop state, the administrator of the communication device 20 near the communication device 20 to change the connection state of the communication A port 2A on the communication device 20 side to an operable state.
