[0007] By their very nature, communication devices are often installed and fixed in various locations. For example, wireless LAN access points may be installed in high, out-of-reach locations such as ceilings or walls to provide a better view of terminal devices. Furthermore, network devices such as switching hubs may be hidden and installed in places that are not easily seen. As networks become larger, the number of network devices increases and they become more scattered, making maintenance and management more time-consuming.

[0015] First, an overview of one embodiment will be described. Note that the reference numerals in the drawings attached to this overview are attached to each element as an example for convenience to facilitate understanding, and the description of this overview is not intended to be limiting in any way. In this disclosure, the drawings relate to one or more embodiments.

[0016] [composition] 1 is a block diagram showing an example of the configuration of a communication device 10 according to the present disclosure. The communication device 10 according to the present disclosure includes an identification information acquisition unit 11, an internal state acquisition unit 12, and a notifying unit 13.

[0017] The identification information acquisition unit 11 acquires the identification information of the device. The internal state acquisition unit 12 acquires the internal state of the device. The notifying unit 13 notifies the internal state.

[0018] One of the features of the communication device 10 in one embodiment is that the identification information acquisition unit 11 acquires the host name of the communication device 10, the internal state acquisition unit 12 acquires the internal temperature of the communication device 10, and calculates the device lifespan of the communication device 10 based on the acquired internal temperature and a predetermined calculation method, and the dissemination unit 13 generates a service set identifier (SSID) of the device from the host name and the device lifespan and disseminates the SSID via a wireless communication network.

[0019] In this way, the communication device 10 of the present disclosure can acquire the internal temperature of the device as the internal state of the communication device using a temperature sensor or the like, calculate the device lifespan based on a predetermined calculation formula, and publicize this using an identifier such as an SSID. A more detailed configuration and the like will be described below.

[0020] [First embodiment] [Processing Overview] 2 is a diagram illustrating an overview of processing by the communication device 10 according to the first embodiment of the present disclosure. This diagram illustrates a scene in which the communication device 10, functioning as a wireless access point, is communicating with a communication device 20 used by a user. The communication device 10 has a built-in temperature sensor, and the internal temperature indicates 45.0°C. To make the internal temperature known, the communication device 10 adds the character string "0450" indicating the internal temperature to the end of its own SSID (Service Set Identifier) ​​and broadcasts the result to provide a connection.

[0021] [composition] An example of the configuration of a communication device 10 according to the first embodiment of the present disclosure can be shown in a block diagram similar to Fig. 1. As shown in this diagram, the communication device 10 according to the first embodiment has an identification information acquisition unit 11, an internal state acquisition unit 12, and a notifying unit 13.

[0022] The identification information acquisition unit 11 acquires identification information of the device, which is information for the device to start communication. Examples of the "information for the device to start communication" include an SSID, a host name, a MAC address (Media Access Control address), an IP (Internet Protocol) address, a login ID, and a password that are required when the communication device 10 connects to a terminal device.

[0023] The internal state acquisition unit 12 acquires the internal state of the device. A "device" is a collection of electronic devices that perform a specific function, including a communication device. Generally, a device is covered with a housing, allowing the inside and outside of the device to be distinguished. A "state" is a parameter that can be measured by a sensor or the like, and examples include temperature and humidity. Therefore, the "internal state of the device" includes "internal temperature," such as the temperature inside the housing, which is inside the device, and the temperature of the electronic device part placed inside the housing.

[0024] The notification unit 13 notifies the internal state. "Notifying" means "to widely notify," and "notifying the internal state" refers to widely notifying the internal state of the device using various means. In the case of the communication device 10, this means notifying by lighting an LED (Light-Emitting Diode) facing outside the device, notifying by changing the color of the light, or notifying by broadcasting via the communication network to which the communication device 10 is connected.

[0025] The notifying unit 13 notifies the internal state of the device, and may notify the internal state by adding the above-obtained identification information before the character string indicating this internal state, as shown in Fig. 2. The reason for adding the identification information before the character string indicating the internal state is to maintain the distinctiveness of the identification information on the network.

[0026] [Explanation of operation] 3 is a flowchart illustrating an example of the operation of the communication device 10 of the present disclosure. As shown in this figure, when the communication device 10 starts operation, it first acquires the internal temperature of the device as the internal state of the device (step S31). Next, it acquires identification information of the device (step S32). Next, it adds the identification information to the acquired internal temperature and notifies it (step S33), and then the process ends.

[0027] [Hardware configuration] Fig. 4 is a block diagram showing an example of a hardware configuration of a communication device 10 according to the present disclosure. The communication device 10 can be configured by an information processing device (computer) and has the configuration shown in Fig. 4. For example, the communication device 10 includes a CPU (Central Processing Unit) 41, a memory 42, an input / output interface 43, and a NIC (Network Interface Card) 44 as a communication means, which are interconnected by an internal bus 45. Note that when the communication device 10 uses wireless communication such as a wireless access point, it further includes a wireless communication module (not shown) which is hardware suitable for the wireless method to be used.

[0028] However, the configuration shown in Fig. 4 is not intended to limit the hardware configuration of the devices that make up the communication device 10. Each communication device 10 may include hardware that is not shown. Furthermore, the number of CPUs and the like included in the communication device 10 is not intended to be limited to the example shown in Fig. 4, and for example, each device may include multiple CPUs.

[0029] The memory 42 is a RAM (Random Access Memory), a ROM (Read Only Memory), or an auxiliary storage device (such as a hard disk).

[0030] The input / output interface 43 is a means for interfacing with a display device or input device (not shown). The display device is, for example, a touch panel display, an LED for indicating the internal state, etc. The input device includes, for example, a device for accepting user operations such as a keyboard or a mouse, as well as a temperature sensor for acquiring the internal temperature of the communication device 10.

[0031] The functions of the communication device 10 are realized by an internal state acquisition program, an identification information acquisition program, a notifying program, and the like, which are processing modules.

[0032] The processing modules are implemented, for example, by the CPU 41 executing a program stored in the memory 42. The program can be updated by downloading it via a network or by using a storage medium storing the program. The processing modules may also be implemented by semiconductor chips. That is, it is sufficient if there is some means for executing the functions performed by the processing modules using some kind of hardware and / or software.

[0033] [Hardware operation] When the communication device 10 starts operating, the internal state acquisition program is first called from the memory 42 by the CPU 41 and placed into an execution state. The program controls the temperature sensor via the input / output interface 43, acquires the temperature at a predetermined location inside the device housing as the internal temperature, and temporarily stores it in the memory 42.

[0034] Next, the identification information acquisition program is called from the memory 42 to the CPU 41 and is put into an execution state. The program acquires the device identification information stored in the memory 42.

[0035] Next, the well-known program is called from the memory 42 to the CPU 41 and is put into an execution state. For example, the program calls the internal temperature temporarily stored in the memory 42 and the acquired identification information, and generates a character string combining a character string indicating the internal temperature and a character string indicating the identification information. The binding string is generated and broadcast to the communication network via the NIC 44 and the wireless communication module.

[0036] [Effect description] As described above, the communication device 10 of this embodiment can acquire the internal temperature as the internal state of the device and disseminate the temperature information together with the device identification information. In other words, it is possible to know the state of the device without preparing a special protocol for disseminating the internal temperature.

[0037] [Second embodiment] [Processing Overview] In the second embodiment, a communication device 10 is described that can measure the internal temperature as the internal state of the device, calculate the device's lifespan using the internal temperature and a predetermined calculation formula, and obtain and publicize device lifespan information including the calculated device lifespan.

[0038] [composition] An example of the configuration of a communication device 10 according to the second embodiment of the present disclosure is similar to that of the above embodiment, and has the configuration shown in Fig. 1. That is, the communication device 10 has an identification information acquisition unit 11, an internal state acquisition unit 12, and a notifying unit 13. These components have already been described in the above embodiment, so only new features will be described below.

[0039] One of the features of the communication device 10 of this embodiment is that the internal state acquisition unit 12 acquires device life information including the device life calculated based on the acquired internal temperature and a predetermined calculation formula.

[0040] The "predetermined calculation formula" is, for example, a calculation formula for calculating the device lifespan. As an example, a wireless access point uses an aluminum electrolytic capacitor, which is a component with a finite lifespan, and the lifespan of this aluminum electrolytic capacitor significantly contributes to the lifespan of the entire device.

[0041] It is generally known that the lifespan of an aluminum electrolytic capacitor roughly follows Arrhenius' law, and the estimated lifespan can be calculated using the following formula. [Number 1] TIFF2025179527000002.tif9150

[0042] where T is the maximum operating temperature [°C], T0 is the operating temperature (ambient temperature + self-temperature rise) [°C], L is the estimated lifespan [hours] at the operating temperature, and L0 is the lifespan [hours] at the maximum operating temperature. T and L0 are given, and the estimated lifespan L at the internal temperature is calculated by substituting the internal temperature T0 acquired by the internal state acquisition unit.

[0043] When the above L: estimated lifespan [hours] at the operating temperature falls below a predetermined time, the notification unit 13 may notify the fact. That is, the notification may be made via a communication network, or by lighting up or changing the color of an LED or the like installed in a device that monitors the device.

[0044] Furthermore, for example, when the communication device 10 is a wireless LAN access point, the notification unit 13 may add the SSID character string acquired by the identification information acquisition unit 11 and the character string indicating the estimated lifespan at the operating temperature L to the end of the SSID character string, and broadcast this as the SSID to potential terminals to connect to.

[0045] Alternatively, the identification information acquisition unit 11 may acquire the hostname (or its set value) of the device on the network, and the notifying unit 13 may notify the hostname of the communication device 10 by adding it to the device's internal state. Specifically, for example, assume that the communication device 10 is a terminal device that is a Dynamic Host Configuration Protocol (DHCP) client. The terminal device can set the hostname, but the process of adding the internal state to the set value of the hostname is performed by the terminal device, which is the communication device 10. For example, if the hostname "Alice" is set to the terminal device, the DHCP client program corresponding to the notifying unit 13 adds the internal temperature "45.0°C" (or the device's lifespan), which is the device's internal state, to the end of "Alice" to lease an IP address to the terminal as "Alice_0450." For example, the hostname "Alice_0450" is updated in the DNS database by the DNS update function of a dynamic Domain Name System (DNS).

[0046] [Explanation of operation] 5 is a flowchart illustrating an example of the operation of the communication device 10 of the present disclosure. As shown in this figure, first, the internal temperature of the device is acquired (step S51). Next, the device lifespan is acquired based on the internal temperature and a predetermined calculation formula (step S52). After this, the device's identification information is acquired (step S53), and the identification information is added before the character string indicating the internal temperature and made public (step S54).

[0047] [Another behavior description] FIG. 6 is a flowchart illustrating another example of the operation of the communication device 10 of the present disclosure. As shown in this figure, first, the internal temperature of the device is acquired (step S61). Next, the device life is acquired by calculating it based on the internal temperature and a predetermined calculation formula. Next, it is determined whether the acquired value of the device life is below a predetermined value (step S63). If the value of the device life is below the predetermined value (step S63, Y), the lighting device notifies the user that the device life has fallen below the predetermined time (step S64). If the value is equal to or greater than the predetermined value (step S63, N), the internal temperature of the device continues to be acquired (step S61).

[0048] [Effect description] As described above, the communication device 10 of this embodiment can calculate the device lifespan based on the internal temperature and a predetermined calculation formula. By adding the calculated device lifespan to the device's identification information, it is possible to easily know when to replace the device or a part of the device.

[0049] [Third embodiment] [Processing Overview] The third embodiment describes an example of an installation mode of the communication device 10 described in the above embodiment. Fig. 7 is a diagram showing an outline of the processing of the communication device 10 according to the embodiment of the present disclosure. As shown in this diagram, when the communication device 10 is a wireless LAN access point, it may be installed, for example, with the antenna pointing downward from the ceiling (10-1), or it may be installed in a mode (10-2) where it is hidden in furniture or the like so that it cannot be seen from the outside, or it may be installed in a mode (10-3) where it is fixed to a wall surface at a high, out-of-reach height with good visibility so that radio waves can reach a wider area.

[0050] That is, the communication device 10 described in embodiments 1 and 2 has a configuration or fixing method that includes a fixing part (not shown) that fixes the device housing to a substantially vertical surface such as a wall surface, or fixes the device housing facing downward to a substantially horizontal surface such as a ceiling.

[0051] For example, the fixing part is fixed to the communication device 10 by passing a screw through gypsum board used as a building material on the wall or ceiling, but it is desirable to fix it to a part of the wall or ceiling that has a base material such as wood behind it so that the screw does not fall out and the device housing does not fall off.

[0052] Furthermore, the present invention provides a communication device 10 and an installation method thereof, in which the communication device 10 described in the first to third embodiments is installed in a concealed location where the device housing cannot be seen from the outside.

[0053] [Effect description] In this way, the communication device 10 of this embodiment can acquire the internal status of a device that is installed by fixing it to a high place such as a ceiling or wall, or to a hidden location such as inside furniture. Even if the device is installed in a way that makes it difficult to reach the device casing and perform a direct internal diagnosis, it is possible to very easily find out the device's lifespan, internal temperature, etc. by using a lighting device such as an LED, or a string of characters that adds the internal status to the identification information via a network.

[0054] [Example] [Configuration example] In the following embodiments, a detailed configuration and operation of a wireless access point to which the present invention is applied will be described. Fig. 8 is a block diagram showing an example of the configuration of a wireless access point 101 according to an embodiment of the present disclosure. As shown in this diagram, the wireless access point 101 according to the embodiment includes a wireless communication unit 102, a temperature sensor 103, a device life prediction unit 104, and a CPU 105.

[0055] The wireless communication unit 102 is a module for wireless communication with a wireless LAN (Local Area Network) terminal 106. The temperature sensor 103 has a function of measuring the internal temperature of the wireless access point 101. The device life prediction unit 104 has a function of predicting the device life based on information about the internal temperature of the device obtained from the temperature sensor 103. The present invention is characterized in that by notifying the user by SSID of information about the device life predicted based on the internal temperature of the device, it is possible to consider maintenance measures such as preventive replacement.

[0056] 9 is a diagram showing the configuration of SSID notification in wireless communication according to the present disclosure. Wireless communication is performed by two devices: a wireless access point 201 and a wireless LAN terminal 202. The wireless access point 201 outputs a beacon containing SSID information composed of an arbitrary character string into the surrounding wireless space, and wireless LAN terminal 202 receives the beacon, enabling wireless communication with the wireless access point 201. The SSID 203 containing the device life expectancy prediction information used in the present invention does not need to be used for wireless communication purposes; the object of the present invention can be achieved by checking the SSID character string information on the wireless LAN terminal. It is also possible to send an SSID 204 for wireless communication separately.

[0057] FIG. 10 is a diagram showing the device lifespan prediction method in this disclosure. Wireless access points use aluminum electrolytic capacitors, which are components with a finite lifespan, and these components are largely responsible for the device lifespan. The lifespan of aluminum electrolytic capacitors generally follows the Arrhenius law, and it is known that the lifespan doubles for every 10°C drop in component temperature. Device lifespan can be predicted by measuring the component temperature with a temperature sensor.

[0058] 11 shows the operation of wireless access point 401 in the present disclosure notifying lifespan prediction information via SSID. Wireless access point 401 transmits the SSID including the lifespan prediction information, which is received by wireless LAN terminal 402. The present invention is characterized in that the lifespan prediction information required for device maintenance can be obtained simply by receiving a beacon at the wireless LAN terminal, without the need to connect via a console or the like.

[0059] 12 is a diagram illustrating an example of the configuration of a wireless access point according to an embodiment of the present disclosure. A CPU 501 includes an SSID string generation unit 502. The SSID string generation unit 502 has a function of generating an SSID string including information about the device lifespan based on information about the device lifespan obtained from a device lifespan prediction unit 503.

[0060] Fig. 13 is a diagram illustrating an example of a configuration of an embodiment of the present disclosure. A wireless access point 601 in Fig. 13 is composed of a wireless communication unit 602, a temperature sensor 603, a device life prediction unit 604, and a CPU 605. The wireless communication unit 602 is a module for notifying a wireless LAN terminal 606 of an SSID. The temperature sensor 603 has a function of measuring the internal temperature of the device. The device life prediction unit 604 predicts the device life based on information obtained by the temperature sensor 603. The CPU 605 generates an SSID string including the device life information calculated by the device life prediction unit 604, and transmits a beacon including the SSID string to the wireless LAN terminal 606 via the wireless communication unit 602.

[0061] FIG. 14 is a diagram showing an example of the operation of an embodiment of the present disclosure. Temperature sensor 701 measures the ambient temperature of aluminum electrolytic capacitor 702. The lifetime value of aluminum electrolytic capacitor 702 is published by the manufacturer, and it can be estimated that the lifetime value doubles for every 10°C decrease in operating temperature compared to the published lifetime value. For example, if the lifetime value of aluminum electrolytic capacitor 702 is 5,000 hours at an operating temperature of 105°C, and the ambient temperature measured by temperature sensor 701 is 95°C, the lifetime value will be 10,000 hours. Device lifetime prediction unit 703 calculates the average temperature T over 24 hours for the ambient temperature measured by temperature sensor 701, and calculates a multiplier X using the following formula: [Number 2] TIFF2025179527000003.tif7150

[0062] The reciprocal Y of the calculated multiplier X is multiplied by 24 hours to obtain the consumed time Tw, and by adding the Tw value obtained every 24 hours and subtracting this from 5000 hours, it is possible to calculate the estimated lifespan L=105 if the product continues to be used at 105°C. The estimated lifespan L=105 multiplied by the multiplier X is the value LX, which is the lifespan if the product continues to be used at the average temperature for 24 hours.

[0063] [Another embodiment of the invention] 15 is a diagram showing a method of notifying the device lifespan by an LED in another embodiment of the present disclosure. When the lifespan prediction information calculated by device lifespan prediction unit 801 becomes less than X hours, an LED 802 mounted on the device housing is turned on (blinked), thereby notifying the maintenance person of the information, thereby achieving an effect equivalent to that of the present invention.

[0064] [Effect description] This invention predicts the device lifespan and includes this information in the SSID string, allowing it to be easily acquired by a wireless LAN terminal. This eliminates the cost of arranging separate equipment such as a console PC or server, and the technical skills required for maintenance.
