[0009] The following describes a wireless communication device 10 according to an embodiment. The wireless communication device 10 according to an embodiment presents to a user information indicating whether or not the current location is an appropriate location for communication.

[0010] (First embodiment) FIG. 1 is a diagram showing a target area in which a plurality of wireless communication devices 10 are installed.

[0011] The multiple wireless communication devices 10 are installed at different positions in a target area, such as indoors or underground. Each of the multiple wireless communication devices 10 may be installed on any object in the target area, such as a ceiling, a floor, a wall, a pillar, or a fixed object.

[0012] The multiple wireless communication devices 10 configure, for example, a wireless IoT system. Each of the multiple wireless communication devices 10 may be, for example, a wireless router device such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). For example, the multiple wireless communication devices 10 are connected to each other by wireless communication to configure a mesh network, a multi-hop network, or the like.

[0013] The target communication device 20 is one of the multiple wireless communication devices 10. The target communication device 20 is a wireless communication device 10 that is to be installed in a target area by a user. For example, the user carries the target communication device 20 in his / her hand and installs it in the target area.

[0014] When the target communication device 20 is carried and installed by a user, the target communication device 20 is set to a measurement mode by the user's operation. When set to the measurement mode, the target communication device 20 presents to the user information indicating whether or not the current location is a suitable location for wireless communication with another wireless communication device 10. This allows the user to find a suitable location for installing the target communication device 20 while carrying the target communication device 20.

[0015] FIG. 2 is a diagram showing an external appearance of the wireless communication device 10 (target communication device 20) according to the first embodiment.

[0016] The wireless communication device 10 has an antenna 24 provided in a housing 22. The antenna 24 wirelessly transmits and receives electromagnetic waves to and from other communication devices. The antenna 24 may be provided inside the housing 22.

[0017] The wireless communication device 10 includes a first display unit 26 and a second display unit 28. The first display unit 26 and the second display unit 28 are provided side by side on one side of the housing 22, for example.

[0018] The first display unit 26 displays information indicating the radio wave intensity of the first signal received from the first device. The first device is any one of the multiple communication devices. The multiple communication devices are multiple wireless communication devices 10 other than the target communication device 20 from which the target communication device 20 can wirelessly receive signals.

[0019] The second display unit 28 displays information indicating the radio wave intensity of the second signal received from the second device. The second device is any one of the multiple communication devices other than the first device. In the first embodiment, the first display unit 26 and the second display unit 28 are each a light-emitting diode that can emit light of a different color.

[0020] FIG. 3 is a diagram showing a functional configuration of the wireless communication device 10 (target communication device 20) according to the first embodiment.

[0021] The wireless communication device 10 includes an operation input unit 32, a wireless communication unit , an allocation unit , a first detection unit , a second detection unit 40, and a presentation unit .

[0022] The operation input unit 32 accepts an operation input by a user. For example, the operation input unit 32 accepts an operation to start the measurement mode when the user carries the wireless communication device 10 and installs it in a target area.

[0023] When the wireless communication unit 34 is set to the measurement mode, it is capable of wirelessly receiving signals from a plurality of communication devices.

[0024] When the measurement mode is set, the allocation unit 36 ​​allocates to the first device one of the plurality of communication devices from which the wireless communication unit 34 can wirelessly receive signals. Also, when the measurement mode is set, the allocation unit 36 ​​allocates to the second device another of the plurality of communication devices, which is different from the first device.

[0025] For example, the allocation unit 36 ​​allocates the communication device that has transmitted the signal with the strongest radio wave intensity among the multiple communication devices during a predetermined period after the start of the measurement mode to the first device. The allocation unit 36 ​​may also allocate the communication device that has transmitted the signal with the second strongest radio wave intensity among the multiple communication devices to the second device.

[0026] Also, for example, the allocation unit 36 ​​may allocate the first communication device among the multiple communication devices that transmits a signal with a radio wave strength equal to or greater than a predetermined value during a predetermined period after the start of the measurement mode to the first device. In this case, the allocation unit 36 ​​allocates the second communication device among the multiple communication devices that transmits a signal with a radio wave strength equal to or greater than a predetermined value to the second device.

[0027] The allocation unit 36 ​​acquires identification information (e.g., a Media Access Control (MAC) address) included in the signal transmitted from the first device, and sets it in the first detection unit 38. The allocation unit 36 ​​also acquires identification information included in the signal transmitted from the second device, and sets it in the second detection unit 40.

[0028] The first detection unit 38 detects the radio wave intensity of the first signal received by the wireless communication unit 34 from the first device. For example, the first detection unit 38 detects a beacon signal including identification information of the first device (e.g., the MAC address of the first device) from among multiple beacon signals received by the wireless communication unit 34, and identifies the detected beacon signal as the first signal. Then, the first detection unit 38 detects the radio wave intensity of the identified first signal. The radio wave intensity is, for example, a value such as LQI (Link Quality Indicator) or RSSI (Received Signal Strength Indication).

[0029] The second detection unit 40 detects the radio wave intensity of the second signal received from the second device by the wireless communication unit 34. For example, the second detection unit 40 detects a beacon signal including identification information of the second device from among multiple beacon signals received by the wireless communication unit 34, and identifies the detected beacon signal as the second signal. Then, the second detection unit 40 detects the radio wave intensity of the identified second signal.

[0030] When the presentation unit 42 is set to the measurement mode, it presents to the user the radio wave intensity of the first signal detected by the first detection unit 38 and the radio wave intensity of the second signal detected by the second detection unit 40. In the first embodiment, the presentation unit 42 has a first display control unit 44, a second display control unit 46, the first display unit 26, and the second display unit 28.

[0031] The first display control unit 44 controls the display of the first display unit 26 based on the radio wave intensity of the first signal detected by the first detection unit 38. When the radio wave intensity of the first signal is greater than a predetermined first threshold value, the first display control unit 44 controls the first display unit 26 to light up in a predetermined first type of light. When the radio wave intensity of the first signal is equal to or less than the first threshold value, the first display control unit 44 controls the first display unit 26 to light up in a predetermined second type of light.

[0032] First display unit 26 lights up in response to control of first display control unit 44. Therefore, first display unit 26 lights up in a first type when the radio wave strength of the first signal is greater than a first threshold value, and lights up in a second type when the radio wave strength of the first signal is equal to or less than the first threshold value. This allows first display unit 26 to notify the user that a signal with a radio wave strength greater than the first threshold value can be received from the first device.

[0033] The first display control unit 44 may control the first display unit 26 to light up in a predetermined third type when the radio wave strength of the first signal is smaller than the second threshold. In this case, the first display unit 26 lights up in the third type when the radio wave strength of the first signal is smaller than the second threshold. The second threshold is smaller than the first threshold. This allows the first display unit 26 to notify the user that a signal of sufficient radio wave strength is not being received from the first device.

[0034] The second display control unit 46 controls the display of the second display unit 28 based on the radio wave intensity of the second signal detected by the second detection unit 40. When the radio wave intensity of the second signal is greater than a predetermined first threshold value, the second display control unit 46 controls the second display unit 28 to light up in a first type of illumination. When the radio wave intensity of the second signal is equal to or less than the first threshold value, the second display control unit 46 controls the second display unit 28 to light up in a second type of illumination.

[0035] Second display unit 28 lights up in response to control of second display control unit 46. Therefore, when the radio wave strength of the second signal is greater than the first threshold, second display unit 28 lights up in the first type, and when the radio wave strength of the second signal is equal to or less than the first threshold, second display unit 28 lights up in the second type. This allows second display unit 28 to notify the user that a signal with a radio wave strength greater than the first threshold can be received from the second device.

[0036] The second display control unit 46 may control the second display unit 28 to turn on the third type of light when the radio wave strength of the second signal is smaller than the second threshold value. In this case, the second display unit 28 turns on the third type of light when the radio wave strength of the second signal is smaller than the second threshold value. The second threshold value is smaller than the first threshold value. This allows the second display unit 28 to notify the user that a signal of sufficient radio wave strength is not being received from the second device.

[0037] Here, the first type of lighting is, for example, a display of a predetermined color (for example, green), and the second type of lighting is a display of a color other than the first type (for example, orange).

[0038] The first type of lighting may be a continuous light. In this case, the second type of lighting is a blinking light at regular intervals.

[0039] The first type of lighting may be a display of characters or a pattern indicating that the signal strength is greater than a first threshold. In this case, the second type of lighting is a display of characters or a pattern indicating that the signal strength is equal to or less than the first threshold.

[0040] Also, the first type of lighting may be lighting of a first number of light-emitting units. For example, the first type of lighting may be lighting of two light-emitting diodes. In this case, the second type of lighting may be lighting of a second number of light-emitting units that is less than the first number. For example, the second type of lighting may be lighting of one light-emitting diode.

[0041] The third type of lighting may be, for example, an off state. The third type of lighting may be a display of a character or a pattern indicating that the radio wave strength of the signal is lower than the second threshold.

[0042] 4 is a flowchart showing the flow of installation processing of the target communication device 20 according to the first embodiment. In the first embodiment, when the target communication device 20 is installed in a target area, the processing proceeds according to the flow shown in FIG.

[0043] First, in S11, the user determines one candidate (first candidate) to be the first device and the second device from among multiple wireless communication devices 10 installed in the target area. Then, the user sets the wireless communication device 10 determined as the first candidate to a communicable state. In this case, the user may correct the position of the wireless communication device 10 determined as the first candidate.

[0044] Next, in S12, the user determines the other candidate (second candidate) of the first device and the second device from among the multiple wireless communication devices 10 installed in the target area. Then, the user sets the wireless communication device 10 determined as the second candidate to a state in which communication is possible. In this case, the user may correct the position of the wireless communication device 10 determined as the second candidate. Also, in this case, the user sets the wireless communication devices 10 other than the first candidate and the second candidate from among the multiple wireless communication devices 10 installed in the target area to a state in which communication is not possible.

[0045] Next, in S13, the user performs an operation to start the measurement mode on the target communication device 20. When a predetermined time has elapsed since the start of the measurement mode, the target communication device 20 assigns one of the first candidate and the second candidate determined in S11 and S12 to the first device, and assigns the other to the second device.

[0046] The target communication device 20 may assign the wireless communication device 10 that has transmitted the signal with the strongest radio wave intensity during a predetermined period after the start of the measurement mode to the first device, and assign the wireless communication device 10 that has transmitted the signal with the second strongest radio wave intensity to the second device. In this case, the user performs an operation to start the measurement mode on the target communication device 20 in the vicinity of the first candidate or the second candidate that the user wishes to set as the first device. This allows the target communication device 20 to allow the user to recognize which of the first candidate and the second candidate determined in S11 and S12 is the first device.

[0047] Next, in S14, the user temporarily places the target communication device 20 within the target area.

[0048] Next, in S15, the user checks the first display unit 26 and the second display unit 28. If the result of checking the first display unit 26 and the second display unit 28 in S15 shows that the radio wave intensity of the signal from one or both of the first device and the second device is equal to or less than the first threshold, the user returns the process to S14. Then, in S14, the user temporarily places the target communication device 20 in a different position and repeats the process again.

[0049] Furthermore, if the result of checking the first display unit 26 and the second display unit 28 in S15 shows that the radio wave intensity of the signal from one or both of the first and second devices is equal to or less than the first threshold value even after the processes of S14 and S15 are executed a predetermined number of times, the user returns the process to S11. Then, in S11, the user corrects the positions of the first and second candidates and repeats the process again.

[0050] If the result of checking the first display unit 26 and the second display unit 28 in S15 shows that the radio field strength of the signals from both the first device and the second device is greater than the first threshold, the user advances the process to S16.

[0051] In S16, the user officially installs the target communication device 20 at the temporarily placed position. Then, when the process of S16 is completed, the user ends the measurement mode of the target communication device 20, and ends this flow.

[0052] As described above, the wireless communication device 10 according to the first embodiment can display to the user a location where wireless communication is possible with both the first device and the second device at a radio wave intensity greater than the first threshold. Therefore, the wireless communication device 10 according to the first embodiment can inform the user that redundant communication will be performed with the first device and the second device. As a result, the wireless communication device 10 according to the first embodiment can present to the user information indicating whether or not the current location is a suitable location for communication.

[0053] Second embodiment Next, a wireless communication device 10 according to a second embodiment will be described. Since the wireless communication device 10 according to the second embodiment has substantially the same functions and configurations as those of the first embodiment, the components having substantially the same functions and configurations are denoted by the same reference numerals and detailed descriptions thereof will be omitted.

[0054] FIG. 5 is a diagram showing the external appearance of a wireless communication device 10 (target communication device 20) according to the second embodiment.

[0055] The wireless communication device 10 according to the second embodiment includes an audio output unit 52. The audio output unit 52 is, for example, a speaker. The audio output unit 52 may be provided on one side of the housing 22, or may be provided inside the housing 22. The audio output unit 52 outputs audio information indicating the radio wave intensity of a first signal received from a first device and the radio wave intensity of a second signal received from a second device.

[0056] FIG. 6 is a diagram showing a functional configuration of the wireless communication device 10 (target communication device 20) according to the second embodiment.

[0057] The wireless communication device 10 according to the second embodiment differs from the first embodiment in the configuration of the presentation unit 42. The presentation unit 42 according to the second embodiment has a sound control unit 54 and a sound output unit 52.

[0058] The audio control unit 54 controls the audio to be output from the audio output unit 52 based on the radio wave intensity of the first signal detected by the first detection unit 38 and the radio wave intensity of the second signal detected by the second detection unit 40. More specifically, the audio control unit 54 causes the audio output unit 52 to output the first audio information, the second audio information, the third audio information, or the fourth audio information.

[0059] The first audio information is a sound indicating that both the radio wave strength of the first signal and the radio wave strength of the second signal are greater than a first threshold. When both the radio wave strength of the first signal and the radio wave strength of the second signal are greater than the first threshold, the audio control unit 54 causes the audio output unit 52 to output the first audio information. Therefore, when both the radio wave strength of the first signal and the radio wave strength of the second signal are greater than the first threshold, the audio output unit 52 outputs the first audio information.

[0060] The second audio information is a sound indicating that the radio wave strength of the first signal is greater than the first threshold value and the radio wave strength of the second signal is not greater than the first threshold value. When the radio wave strength of the first signal is greater than the first threshold value and the radio wave strength of the second signal is not greater than the first threshold value, the audio control unit 54 causes the audio output unit 52 to output the second audio information. Therefore, when the radio wave strength of the first signal is greater than the first threshold value and the radio wave strength of the second signal is not greater than the first threshold value, the audio output unit 52 outputs the second audio information.

[0061] The third audio information is a sound indicating that the radio wave strength of the first signal is not greater than the first threshold value and that the radio wave strength of the second signal is greater than the first threshold value. When the radio wave strength of the first signal is not greater than the first threshold value and that of the second signal is greater than the first threshold value, the audio control unit 54 causes the audio output unit 52 to output the third audio information. Therefore, when the radio wave strength of the first signal is not greater than the first threshold value and that of the second signal is greater than the first threshold value, the audio output unit 52 outputs the third audio information.

[0062] The fourth audio information is a sound indicating that both the radio wave strength of the first signal and the radio wave strength of the second signal are not greater than the first threshold. When both the radio wave strength of the first signal and the radio wave strength of the second signal are not greater than the first threshold, the audio control unit 54 causes the audio output unit 52 to output the fourth audio information. Therefore, when both the radio wave strength of the first signal and the radio wave strength of the second signal are not greater than the first threshold, the audio output unit 52 outputs the fourth audio information.

[0063] Note that, when both the radio wave intensity of the first signal and the radio wave intensity of the second signal are smaller than the second threshold value, the audio control unit 54 may output the fifth audio information from the audio output unit 52. Therefore, when both the radio wave intensity of the first signal and the radio wave intensity of the second signal are smaller than the second threshold value, the audio output unit 52 outputs the fifth audio information.

[0064] Here, the first voice information is, for example, a continuous sound of the first level. The second voice information is, for example, an intermittent sound of the first level. The third voice information is, for example, an intermittent sound of the first level, with an interval different from that of the second voice information. Note that the second voice information and the third voice information may be the same. Also, the fourth voice information is an intermittent sound or a continuous sound that is smaller than the first level.

[0065] The first voice information may be a voice reading out text indicating that both the radio wave strength of the first signal and the radio wave strength of the second signal are greater than a first threshold value. The second voice information is a voice reading out text indicating that the radio wave strength of the first signal is greater than the first threshold value and that the radio wave strength of the second signal is not greater than the first threshold value.

[0066] The third voice information is a voice reading out text indicating that the radio wave strength of the first signal is not greater than the first threshold value and that the radio wave strength of the second signal is greater than the first threshold value. The second voice information and the third voice information may be a voice reading out text indicating that one of the first signal and the second signal is greater than the first threshold value and the other is not greater than the first threshold value. The fourth voice information may be a voice reading out text indicating that both the radio wave strength of the first signal and the radio wave strength of the second signal are not greater than the first threshold value.

[0067] The fifth audio information may be silent or may be audio reading out text indicating that both the radio wave strength of the first signal and the radio wave strength of the second signal are less than the second threshold.

[0068] 7 is a flowchart showing the flow of installation processing of the target communication device 20 according to the second embodiment. In the second embodiment, when the target communication device 20 is installed in a target area, the processing proceeds according to the flow shown in FIG.

[0069] The installation process according to the second embodiment is different from the process according to the first embodiment shown in FIG. 4 in that the process of S15 is replaced by S21.

[0070] In S21, the user checks the sound output from the sound output unit 52. If the result of checking the sound output from the sound output unit 52 in S21 indicates that the radio wave intensity of the signal from one or both of the first device and the second device is equal to or less than the first threshold, the user returns the process to S14. Then, in S14, the user temporarily places the target communication device 20 in a different position and repeats the process again.

[0071] Furthermore, if the result of checking the audio output from audio output unit 52 in S21 shows that the radio wave intensity of the signal from one or both of the first and second devices is equal to or less than the first threshold value even after the processes of S14 and S21 are executed a predetermined number of times, the user returns to the process of S11. Then, in S11, the user corrects the positions of the first and second candidates and repeats the process again.

[0072] If, as a result of checking the audio output from audio output unit 52 in S21, the radio field strength of the signals from both the first device and the second device is greater than the first threshold, the user advances the process to S16.

[0073] In S16, the user officially installs the target communication device 20 at the temporarily placed position. Then, when the process of S16 is completed, the user ends the measurement mode of the target communication device 20, and ends this flow.

[0074] As described above, the wireless communication device 10 according to the second embodiment can output to the user a voice of a location where wireless communication is possible with both the first device and the second device at a radio wave intensity greater than the first threshold. Therefore, the wireless communication device 10 according to the second embodiment can inform the user that redundant communication will be performed with the first device and the second device. As a result, the wireless communication device 10 according to the second embodiment can present to the user information indicating whether or not the current location is a suitable location for communication.

[0075] (Hardware configuration of wireless communication device 10) 8 is a diagram showing an example of a hardware configuration of the wireless communication device 10. The wireless communication device 10 can be realized by, for example, the configuration shown in FIG.

[0076] The wireless communication device 10 has the same configuration as a normal computer (information processing device) having a wireless communication function. That is, the wireless communication device 10 has a CPU 201 (Central Processing Unit), a ROM 202 (Read Only Memory), a RAM 203 (Random Access Memory), a storage device 204, an operation input unit 32, a wireless communication unit 34, a monitor unit 206, and a speaker unit 208. The CPU 201, the ROM 202, the RAM 203, the storage device 204, the operation input unit 32, the wireless communication unit 34, the monitor unit 206, and the speaker unit 208 are connected by a bus.

[0077] The CPU 201 loads a program stored in the storage device 204 into the RAM 203 and executes it, controls each unit to perform input / output, and processes data. The ROM 202 stores a start program that reads an OS startup program from the storage device 204 to the RAM 203. The RAM 203 stores data as a working area for the CPU 201.

[0078] The storage device 204 is, for example, a hard disk drive or a flash memory. The storage device 204 stores an operating system, application programs, and data. These programs may be distributed by being recorded on a computer-readable recording medium in the form of installable or executable files. The programs may also be distributed by being downloaded from a server.

[0079] The operation input unit 32 is a button, a keyboard, etc., and accepts operation input by a user and provides the input to the CPU 201. The wireless communication unit 34 wirelessly transmits and receives signals to and from other communication devices under the control of the CPU 201. The monitor unit 206 displays information under the control of the CPU 201. The monitor unit 206 may function as the first display unit 26 and the second display unit 28. The speaker unit 208 outputs information as sound under the control of the CPU 201. The speaker unit 208 may function as the audio output unit 52.

[0080] The program executed by the wireless communication device 10 of the present embodiment is provided by being recorded in a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a DVD in the form of an installable or executable file. The program executed by the wireless communication device 10 of the present embodiment may be provided by being stored on a computer connected to a network such as the Internet and downloaded via the network. The program executed by the wireless communication device 10 of the present embodiment may be provided or distributed via a network such as the Internet. The program of the present embodiment may be provided by being pre-installed in the ROM 202 or the like.

[0081] The program executed by the wireless communication device 10 includes an allocation module, a first detection module, a second detection module, and a presentation module.

[0082] In the wireless communication device 10, the processor (CPU 201) reads out a program from a storage medium (such as the storage device 204) and executes it, whereby each module is loaded onto the main storage device (RAM 203), and the processor (CPU 201) functions as an allocation unit 36, a first detection unit 38, a second detection unit 40, and a presentation unit 42. Note that in the wireless communication device 10, some or all of the allocation unit 36, the first detection unit 38, the second detection unit 40, and the presentation unit 42 may be realized by hardware.
