Description

  Embodiments described herein relate generally to a wireless system, a setting method of a correspondence relationship between installation position information and address information of a plurality of devices, and a program.

  Conventionally, when a plurality of devices included in a monitoring system, a control system, and the like communicate with a control device, communication is performed using identification information of each device, for example, address information.

  For example, in a system that controls a plurality of lighting fixtures installed in a building or the like, the control device controls each lighting fixture by sending a control command to which address information of each lighting fixture is added. In addition, the control device controls the lighting of each lighting fixture installed in the facility by associating the location information indicating where each lighting fixture is installed in the facility such as a building with the address information. be able to.

  The correspondence between the lighting equipment physically installed in the facility and the address information for communication is, for example, that after the control device and a plurality of lighting fixtures are installed, a lighting command is sent from the control device to the lighting fixture of known address information. This is done by visually confirming which lighting fixture is turned on by the operator, and information on the correspondence between the installation position information of each lighting fixture and the address information is registered in the control device.

  The work for such association must be performed for all the luminaires, and there is a problem that it takes time.

  In recent years, there are devices having a wireless communication function. For example, in the case of a luminaire having a wireless communication function, the control device controls each luminaire by wirelessly sending a control command to which address information of each luminaire is added.

  In the case of a wireless device, the correspondence between the installed lighting fixture and address information is, for example, transmitting a beacon signal from the lighting fixture, and a setting device such as a tablet terminal having a wireless communication function receives the beacon signal, Based on the address information included in the beacon signal, it is also possible to associate the installed lighting fixture with the address.

  The propagation distance of the beacon signal generally depends on the output intensity of the radio wave of the transmitter that outputs the beacon signal. Moreover, it is thought that the reception intensity | strength of the beacon signal from the apparatus nearest to a setting apparatus becomes the largest among the beacon signals received in the setting apparatus.

  However, according to the experiment conducted by the applicant, in the case of a device installed in a facility such as a building, in reality, the reception intensity is the highest in the beacon signal received by the setting device due to the influence of radio wave reflection and the like. It has been found that the device that outputs a large beacon signal may not be the device closest to the setting device.

  Accordingly, there is a problem that if the installation position information and address information of an installed device are associated using the above-described reception intensity, incorrect correspondence information is created.

Each control device 13 is communicably connected to a plurality of devices 14 by a wireless communication line WL using a predetermined protocol. Here, the predetermined protocol is a protocol in accordance with the Bluetooth (registered trademark) Low Energy standard.
Note that the predetermined protocol may be a protocol other than the Bluetooth (registered trademark) Low Energy standard.

  The management device 11 is a personal computer, for example, and includes a keyboard, a mouse, a monitor, and the like. The administrator of the wireless system 1 can set various control programs to be executed, a time schedule, and the like for each gateway device 12 while watching the monitor. Further, the administrator can also make various settings for each device 14.

  The gateway device 12 is, for example, a box computer, relays various command signals from the management device 11 received via the communication line L1, executes processing according to the received command signals, and according to a time schedule. A command signal is output to the control device 13.

  The control device 13 includes, for example, a microcomputer, generates a control command signal according to a command signal from the gateway device 12, outputs the control command signal to the wireless communication line WL, and states the devices 14 via the wireless communication line WL. Signals and detection signals from various sensors are received. Signals for monitoring and controlling each device 14 are transmitted from the control device 13 via the wireless communication line WL.

  The wireless communication between the control device 13 and each device 14 is performed using the address information of each device 14. The address information is identification information for identifying each device 14 in order to communicate with the plurality of devices 14. Therefore, in wireless communication, the control device 13 can send a predetermined command to a desired device 14 by transmitting a command signal to which the address information of the device 14 is added. That is, the control device 13 controls each device 14 using the address information. Each device 14 can determine whether the command is addressed to itself based on the address information included in the received command signal.

  In FIG. 1, the gateway device 12 and the control device 13 are separate bodies, but may be configured as one control device having both functions of the gateway device 12 and the control device 13.

The plurality of devices 14 include a lighting fixture 15, an illuminance sensor 16, a human detection sensor 17, and the like. Each device 14 is a wireless device having a wireless communication function.
The gateway device 12 controls the control device 13 via the communication line L2 so as to control each lighting device 15 in the building according to the time schedule for each area in the building.

  Further, the gateway device 12 acquires information from the plurality of devices 14 via the control device 13 and transmits the requested information to the management device 11 in response to a transmission request from the management device 11.

  A plurality of control devices 13 and a plurality of devices 14 are installed in the building. As described above, a plurality of lighting fixtures 15, a plurality of illuminance sensors 16, and a plurality of human detection sensors 17 are connected to each control device 13 as the device 14.

Each control device 13 performs on / off control or dimming control of the lighting fixture 15 based on a human detection signal of the human detection sensor 17 or the like. Furthermore, each control device 13 outputs a control command for turning on or off the lighting fixture 15 to the wireless communication line WL in accordance with a command from the management device 11.
Further, each control device 13 receives the setting information of each device 14 from the management device 11 and transmits it to each device 14.

  FIG. 2 is a layout diagram showing installation positions of a plurality of devices. The layout diagram is displayed on a monitor of the management apparatus 11 or the like. If there are multiple rooms in the building, a layout diagram is created for each room. The layout diagram shows the arrangement positions of one or more devices 14 installed in the room.

The layout diagram of FIG. 2 shows a plan view of one room of a building, and a plurality of lighting fixtures 15, a plurality of illuminance sensors 16, and a plurality of human detection sensors 17 are installed in a rectangular room.
The layout diagram is related to the lighting control, and the administrator can select the device 14 displayed in the layout diagram and transmit a command to the selected device 14 to be used for the lighting control. That is, the layout diagram can also be used by the administrator to control or monitor the device 14.

  The management device 11, the gateway device 12, and the control device 13 have correspondence information that associates the installation position information of each device 14 with the address information of each device 14. The correspondence information is stored in the respective memories of the gateway device 12 and the control device 13.

The correspondence information is created by a setting device 31 described later, transmitted from the setting device 31 to the gateway device 12 and the control device 13, and stored in each memory.
As described above, the management device 11 can control each device 14 and acquire information from each device 14 by transmitting various commands to the gateway device 12. Various commands include address information of the device 14 that communicates.

  In the case of illumination control, for example, which area the illuminance sensor 16 detects the illuminance is set in advance on the layout of the room. The gateway device 12 and the control device 13 perform dimming control of one or more lighting fixtures 15 that illuminate the corresponding area based on the illuminance detected by the illuminance sensor 16.

  Therefore, the management device 11, the gateway device 12, and the control device 13 can perform lighting control of the building based on the information on the correspondence between the installation position information and address information of each device 14 in the building.

  The management device 11 stores data such as the layout diagram of the equipment in the building and the equipment configuration diagram in the storage device. The administrator displays these data on the monitor of the management device 11. The various devices 14 can be monitored and controlled.

Next, the configuration of the device 14 will be described. Here, the structure of the lighting fixture 15 is demonstrated.
FIG. 3 is a block diagram illustrating a configuration of the lighting fixture 15 which is a wireless device.

  The lighting fixture 15 includes a control unit 21, a wireless communication interface circuit (hereinafter abbreviated as wireless communication I / F) 22, a power supply circuit 23, and a light emitting element unit 24. Note that each device 14 such as the lighting fixture 15 is supplied with power from a power line (not shown).

The control unit 21 includes a processor 21a and a storage device 21b.
The processor 21a includes a central processing unit (hereinafter referred to as a CPU), a memory such as a ROM and a RAM. Various functions of the lighting fixture 15 are realized by the CPU executing the program stored in the ROM.

In the ROM of the processor 21a, address information determined and written by the administrator for specifying the lighting fixture 15 is also stored. This address information is used for wireless communication with the control device 13.
The processor 21a may be configured by an integrated circuit such as an FPGA (Field Programmable Gate Array).

  Furthermore, the luminaire 15 may have a rewritable and non-volatile memory 21c as shown by a dotted line in FIG. 3, and store address information in the memory 21c. The processor 21a reads the address information from the memory 21c and uses it for wireless communication with the control device 13.

  The wireless communication I / F 22 is a wireless module including a circuit that performs wireless communication with the control device 13 using a predetermined protocol. The wireless communication I / F 22 performs communication according to, for example, Bluetooth (registered trademark) Low Energy standards.

The power supply circuit 23 is a circuit that supplies power to the light emitting element unit 24.
The light emitting element unit 24 includes one or more light emitting diodes (hereinafter referred to as LEDs) for illumination.

The control unit 21 receives a command from the control device 13 via the wireless communication I / F 22, generates a control signal corresponding to the command signal, and outputs the control signal to the power supply circuit 23.
The power supply circuit 23 generates a drive current according to a control signal from the control unit 21 and outputs the drive current to the light emitting element unit 24.

  The lighting fixture 15 can receive a command signal from the control device 13 via the wireless communication I / F 22 and can transmit various information such as a dimming state signal to the control device 13.

The control unit 21 sets the reception strength when receiving radio waves by wireless communication and the output strength when transmitting radio waves to the wireless communication I / F 22.
Here, each device 14 can transmit radio waves at two intensity levels.

Further, each device 14 has two operation modes. The two operation modes are an association non-setting mode and a normal mode.
The association non-setting mode is an operation mode when the correspondence between the installation position information of the device 14 and the address information is not set. In the association non-setting mode, the device 14 transmits a beacon signal described later.

  The normal mode is an operation mode in which the correspondence relationship between the installation position information of the device 14 and the address information is set, the device 14 receives a command from the control device 13, and can execute an operation according to the received command. It is.

  Note that, when the power switch of each device 14 is switched from OFF to ON, the operation mode of each device 14 is the association non-setting mode. In the normal mode, the device 14 performs wireless communication with the control device 13.

  The control unit 21 changes the output intensity at the time of radio wave transmission according to the operation mode. That is, each device 14 can switch between a first output intensity when transmitting a beacon signal, which will be described later, and a second output intensity when transmitting a radio wave signal in wireless communication with the control device 13. .

Therefore, the control unit 21 has output intensity data for each mode. The output intensity data for each mode is stored in, for example, a ROM as table data.
FIG. 4 is a diagram illustrating a structure of table data for storing output intensity data of radio waves for each mode.

  As shown in FIG. 4, the table TBL stores output intensity data L1 in the normal mode and output intensity data L0 in the association non-setting mode. The output intensity data L0 is smaller than L1.

  In the normal mode, the control unit 21 reads the output intensity data L1 from the table TBL and sets it in the wireless communication I / F 22. The wireless communication I / F 22 outputs radio waves with the set output intensity data L1.

  The control unit 21 reads the output intensity data L0 from the table TBL and sets it in the wireless communication I / F 22 in the association non-setting mode. The wireless communication I / F 22 outputs radio waves with the set output intensity data L0.

Note that the reception intensity at the time of reception of radio waves is constant in the plurality of devices 14 regardless of the operation mode.
When the wireless communication I / F 22 is also compatible with the mesh network, the control unit 21 determines the two reception strengths, that is, the reception strength in the normal mode and the reception strength for the mesh network, as described above. / F22 can be set.

  The control unit 21 controls the wireless communication I / F 22 and outputs a beacon signal at a constant period when in the association non-setting mode. The beacon signal is broadcast information including address information of the device 14 that outputs the beacon signal.

  Other devices 14 such as the illuminance sensor 16 and the human detection sensor 17 also have a wireless communication I / F similar to the wireless communication I / F 22 and the control unit 21 and can receive commands from the control device 13. The detection signal of the sensor can be transmitted to the control device 13. The other devices 14 such as the illuminance sensor 16 and the human detection sensor 17 also have the two operation modes described above, and the control unit 21 controls the wireless communication I / F 22 in the association non-setting mode. The beacon signal is output at a constant cycle.

  That is, each device 14 has a wireless communication I / F 22 for communicating with a predetermined communication protocol, and can transmit a predetermined radio wave signal including address information, here, a beacon signal at a predetermined cycle.

  In the wireless system 1, in order to associate the installation position information of each device 14 installed in the building with the address information, an operator holds a setting device in the building and is in the vicinity of each device 14. The address information of each device 14 is acquired.

  Here, the address information of each device 14 is an address that is set for each device 14 in order for the control device 13 to specify each device 14 and is written in the processor 21a. A unique communication address for wireless communication included in the wireless communication I / F 22 may be used.

  FIG. 5 is a diagram for explaining a method of associating a plurality of devices 14 installed in a building with address information. In FIG. 5, it is the figure which looked at the room from the horizontal direction, and the floor F and the ceiling C in which the some apparatus 14 was installed are shown.

In FIG. 5, the lighting fixture 15, the human detection sensor 17, etc. are installed in the ceiling C in the room.
The worker P stands in the vicinity of the device 14 to be associated in the building and receives a beacon signal from each device 14 by the setting device 31. The setting device 31 is, for example, a tablet terminal or a smartphone capable of communication according to the Bluetooth (registered trademark) low energy standard.

  As will be described later, the operation mode of each device 14 can be changed in accordance with a predetermined command from the outside, and the operation mode of the device 14 when the power is turned on is an association non-setting mode. Therefore, when the device 14 is in the association non-setting mode, the radio wave output from each device 14 is small.

Each device 14 transmits a beacon signal at a predetermined cycle after the power is turned on.
The worker P receives the beacon signal from each device 14 while standing in the vicinity of the device 14 in which the setting device 31 is to be associated with the installation position removal information and the address information. In FIG. 5, the setting device 31 receives a beacon signal while standing directly below the lighting fixture 15 </ b> A.

  Since each device 14 outputs a beacon signal in the association-unset mode, the reach of radio waves is not large.

  As will be described later, the worker selects the device 14 installed closest to the worker P from the device list displayed on the setting device 31.

FIG. 6 is a block diagram illustrating a configuration of the setting device 31.
The setting device 31 includes a control unit 41, a wireless communication I / F 42, a liquid crystal display device (hereinafter referred to as LCD) 43, and a touch panel device 44.

The control unit 41 includes a processor 41a and a storage device 41b.
The processor 41a includes a memory such as a CPU, a ROM, and a RAM. When the CPU executes a program stored in the ROM, various processes such as an association process described later are executed.

The processor 41a may be configured by an integrated circuit such as an FPGA (Field Programmable Gate Array).
The wireless communication I / F 42 is a wireless communication unit including a circuit that performs wireless communication with the control device 13 and each device 14 using a predetermined protocol.

Here, the wireless communication I / F 42 is a wireless module that performs communication according to, for example, the Bluetooth (registered trademark) low energy standard.
The control unit 41 receives a radio signal via the wireless communication I / F 42. In addition, the control unit 41 transmits correspondence information described later to the gateway device 12 via the wireless communication I / F 42.

The LCD 43 is a display that displays the image generated by the control unit 41.
The touch panel device 44 is arranged on the screen of the LCD 43 and outputs touch position information of the touch panel device 44 touched by a worker with a finger or the like.

  The control unit 41 displays various images, operation buttons, check boxes, and the like on the screen of the LCD 43, and determines the position on the screen touched by the operator based on the touch position information from the touch panel device 44. Therefore, the control unit 41 can detect the operation of the operation button based on the touch position information from the touch panel device 44 and execute processing corresponding to the operation.

A correlation processing program to be described later is stored in the storage device 41b and read and executed by the processor 41a.
The setting device 31 can receive radio signal from each device 14 and transmit various command signals to each device 14 via the wireless communication I / F 42.

The output intensity of the radio wave of the setting device 31 is an intensity at which the radio wave can be transmitted not only to the plurality of devices 14 installed in the building but also to the gateway device 12 and the control device 13.
The storage device 41b stores installation position information of each device 14 in the building along with the layout diagram in the building. By association processing described later, the address information of each device 14 is associated with the installation position information of each device 14 and stored in the storage device 41b.

Here, the setting device 31 is a tablet terminal, but may be a dedicated machine.
(Function)
Next, the association process will be described.
FIG. 7 is a flowchart showing an example of the flow of association processing in the setting device 31.

For example, as shown in FIG. 5, the worker P stands under the lighting fixture 15 </ b> A and displays a layout diagram of a room to be associated with the LCD 43.
FIG. 8 is a diagram illustrating an example of a setting screen including a layout diagram displayed on the display screen of the setting device 31. FIG. 8 is the same layout diagram as the layout described in FIG. The setting screen 51 in FIG. 8 includes a layout diagram display unit 52 and a setting button 53.

  The operator touches the luminaire 15A in the setting screen 51 to bring the luminaire 15A into a selected state. In FIG. 8, the mark of the lighting fixture 15A is shown in black, and it is possible for the operator to determine that the touch has been made.

After the selection, when the operator touches the setting button 53, the processing of FIG. 7 is executed.
When the processing of FIG. 7 is started, the control unit 41 determines whether a beacon signal is received via the wireless communication I / F 42 (step (hereinafter abbreviated as S) 1).

Even if each device 14 is in the association non-setting mode and the output intensity of the radio wave is small, the beacon signal from each device 14 reaches the setting device 31 as shown in FIG.
5 includes a lighting fixture 15A closest to the setting device 31, a human detection sensor 17A farther from the setting device 31 than the lighting fixture 15A, and a lighting fixture 15B further away from the setting device 31 than the human detection sensor 17B. It is shown that a plurality of beacon signals from the device 14 reach the setting device 31 as indicated by dotted lines.

Therefore, the setting device 31 receives a plurality of beacon signals from a plurality of peripheral devices 14. If no beacon signal is received (S1: NO), no processing is performed.
When a beacon signal is received in S1 (S1: YES), the control unit 41 counts the number of received beacon signals (S2). Since the beacon signal includes address information, the control unit 41 counts the number of times the beacon signal is received within a predetermined time for each address information. That is, the setting device 31 can receive a beacon signal as a predetermined radio signal, and the process of S2 is performed at a predetermined time of a predetermined radio signal for each device 14 based on the address information included in the predetermined radio signal. A measurement unit for measuring the number of receptions is configured.

  The control unit 41 displays the number of times counted for each address information by the measuring unit S2 (S3). In other words, the LCD 43 serving as a display displays the plurality of devices 14 and the number of receptions of each of the plurality of devices 14 measured in S2.

Next, it is determined whether or not the address information has been selected by the worker P (S4).
FIG. 9 is a diagram illustrating an example of a display screen of the setting device 31. FIG. 9 shows a number display screen 61 for displaying the number of receptions within a predetermined time for each address information.

  As a result of the process of S3, a frequency display screen 61 for displaying the number of receptions for each address information counted in S2 in a list format is displayed on the LCD 43 of the setting device 31. The number display screen 61 has a list display section 62 and a selection button 63.

  The list display unit 62 displays address information together with the number of receptions in a list format in descending order of the number of receptions. Therefore, the highest address information in the list is the address with the highest number of receptions.

  In FIG. 9, the number of receptions of the beacon signal at the address “001002” is “20”, which is the largest. This address “001002” is an address of the lighting fixture 15A. The address “001101” is the address of the human detection sensor 17A, and the address “002123” is the address of the lighting fixture 15B.

  The operator sees the display of the number of receptions shown in FIG. 9, and when the address “001002” of the device with the highest number of receptions is associated with the lighting fixture 15A, touching the selection button 63 causes the address with the highest number of receptions. “001002” is associated with the lighting fixture 15A.

Therefore, the control unit 41 determines whether the selection button 63 is touched (S4). If the selection button 63 is not touched (S4: NO), the process returns to S1.
If the selection button 63 is not touched (S4: NO), the processing from S1 to S3 is repeated, so that the value of the number of receptions in the list display unit 62 in the number display screen 61 of FIG. 9 increases in real time. Change.

  When the selection button 63 is touched (S4: YES), the control unit 41 associates the address “001002” with the lighting fixture 15A selected in FIG. 7 (S5). That is, the process of S5 constitutes a setting unit that sets information on the correspondence between the installation position information of each device 14 and the address information of each device 14 based on the number of receptions measured by the measurement unit of S2. In the process of S5, which is the setting unit, correspondence information is generated by associating the address information of the device 14 with the highest number of receptions with the device 14 specified in the setting device 31.

After S5, the control unit 41 registers the correspondence information in the storage device 41b (S6).
For example, in the association process of S5, the control unit 41 creates data in which the installation position information of the lighting device 15A selected in FIG. 7 is associated with the address information included in the beacon signal with the highest number of receptions, In the process of S6, the data is stored in a predetermined table as table data.

FIG. 9 shows the number display screen 61 when the beacon signal is transmitted with a weak output intensity because each device 14 is operating in the non-corresponding mode.
It is conceivable that the beacon signal is output at a normal output intensity, for example, 0 dB (decibel), and the address information of the beacon signal having the highest radio wave reception intensity is associated with the luminaire 15A closest to the setting device 31.

However, since the reception strength of the beacon signal varies depending on the structure of a facility such as a building, the arrangement position of each device 14, etc., if the installation position information of the device 14 is associated with the device 14 having the highest reception strength, There is a case where the attachment is wrong. Therefore, as a result of various studies by the applicant, it has been found that there is a correlation between the number of times the beacon signal is received and the distance from each device 14. Furthermore, this correlation is dependent on the signal strength of the beacon signal, and it has been found that if the signal strength is set below a certain level, there is a correlation between the number of times the beacon signal is received and the distance from each device 14.
For example, when the output intensity of the beacon signal is measured with the output intensity of the radio wave of each device 14 being the same as the output intensity in the normal mode, the number of times as shown in a two-dot chain line in FIG. 9 is measured. The That is, in this case, a beacon signal transmitted from a device (address 00101, 002123) disposed at a position farther than the number of times of reception of a beacon signal transmitted from a device (address 00102 in this case) disposed closest to the device. It can be said that there is no correlation between the number of beacon signals received and the distance from each device 14.

Therefore, as described above, the radio wave output intensity of each device 14 is made smaller than that in the normal mode, and the association between the installation position information of the device and the address information based on the number of reception times of the beacon signal is confirmed. Proved to be accurate. More precisely, when the output strength of the radio wave of each device 14 is lowered, if the output strength falls below a certain level, the accuracy of the correspondence between the installation position information and address information of the device with the highest number of receptions However, it turned out to be suddenly high.
Therefore, here, in the association non-setting mode, the output intensity of the radio wave of each device 14 is set to an intensity at which the device closest to the setting device 31 can be identified as the device having the largest number of receptions.

  In the present embodiment, the radio wave output intensity of each device 14 is set to 0 dB (decibel) in the normal mode, and the radio wave output intensity of each device 14 is set to −30 dB (decibel), for example, in the non-association mode. Is set. Therefore, in the association non-setting mode, a beacon signal is output with an output intensity smaller than that in the normal mode.

  By reducing the output intensity in this way, the correspondence between the address information of the beacon signal with the highest number of receptions and the installation position information of the installed device 14, that is, the device 14 closest to the setting device 31, is correctly performed. Can do.

  Accordingly, the selection of the device 14 in FIG. 8 and the execution of the processing in FIG. 7 are performed for each device 14, whereby the installation position information of the devices 14 and the address information are associated with each other.

When the association for all the devices 14 is completed, the worker executes a process for shifting the operation mode of each device 14 to the normal mode.
The operator gives the setting device 31 a command (not shown) to cause the setting device 31 to execute the process of FIG.

FIG. 10 is a flowchart illustrating an example of a flow of mode change processing for changing the mode of all the devices 14.
When the command from the operator is input, the control unit 41 executes the process of FIG. The control unit 41 determines whether the input command is a mode change command (S11).

When the input command is a mode change command (S11: YES), the control unit 41 transmits a mode change command (S12).
In the mode change, for example, the control unit 41 displays a selection screen for selecting one of the two operation modes on the screen of the setting device 31 and instructs to switch to the mode selected by the operator. Send a mode change command. The mode change command is transmitted from the setting device 31 to the control device 13, and the mode change command is transmitted from the control device 13 to all the devices 14.

The blinking instruction command may be transmitted directly from the setting device 31 to all the devices 14.
Upon receiving the mode change command, each device 14 switches the operation mode to the designated mode.

  In the above case, when the operator inputs an instruction to change the operation mode to the normal mode to the setting device 31, a mode change command for changing the operation mode to the normal mode is simultaneously transmitted to the plurality of devices 14, and the mode change command is transmitted. The operation modes of all the received devices 14 are simultaneously changed from the unmatched mode to the normal mode.

  As described above, after setting the correspondence relationship for the plurality of devices 14, the setting apparatus 31 transmits a mode change command for changing the operation mode of the plurality of devices 14 to the plurality of devices.

When the input command is not a mode change command (S11: NO), the control unit 41 performs no processing.
As described above, after the association between the installation position information and the address information of each installed device 14 is completed for all the devices 14, each device 14 is set to the normal mode by the mode change process, and the control device The command from 13 is received and the operation according to the command is performed.

When the operation mode is the normal mode, the output intensity of the radio wave of each device 14 is an intensity capable of communicating with the control device 13.
Therefore, each device 14 can transmit a status signal or the like to the control device 13.

Note that when the operation mode changes from the non-corresponding setting mode to the normal mode, the control unit 41 controls the wireless communication I / F 42 to stop the transmission of the beacon signal.
