[Embodiment]
[Estimation system]
First, an arrangement example of the estimation system 100 according to the embodiment will be described with reference to FIG. FIG. 1 is a diagram showing an arrangement example of an estimation system according to an embodiment.

The estimation system 100 shown in FIG. 1 has a plurality of installation objects 10 arranged on the floor 1 and an estimation device 20. The estimation device 20 estimates, for example, in which space 2 to 4 the plurality of installation objects 10 connected to the estimation device 20 are arranged in the floor 1 having the plurality of spaces 2 to 4. Further, the estimation device 20 may, for example, estimate in detail at which position in the spaces 2 to 4 the specific installation object 10 to which a predetermined address is assigned is arranged.

The installation object 10 for which the arrangement position is estimated is, for example, a lighting device having a light source. The lighting device may be, for example, a security light or an emergency light. The installation object 10 is not limited to the lighting device. The installation object 10 may be, for example, various sensors such as a motion sensor and a temperature sensor. Further, the installation object 10 may be, for example, an air conditioner, a speaker, an alarm device or other emergency equipment, or an image pickup device such as a security camera or a surveillance camera. Further, the installation object 10 is not limited to the case where it is integrated with the estimation target, and may be built in the estimation target or may be attached to the estimation target, for example. The installation object 10 may be located below the ceiling and can be visually recognized by the worker in the floor 1 or the spaces 2 to 4, and may be located above the ceiling. May not be easily visible.

The estimation device 20 is, for example, a terminal device such as a smartphone or a tablet terminal. The estimation device 20 may be, for example, a dedicated device, or may be a device that starts an application and executes an estimation process. Further, the estimation device 20 may be, for example, a desktop PC (Personal Computer) or a notebook PC. Further, the estimation device 20 may also serve as, for example, a controller (not shown) for remotely operating the lighting device.

Next, the outline of the estimation system 100 according to the embodiment will be described with reference to FIG. FIG. 2 is a diagram showing an outline of the estimation system according to the embodiment. In addition, in FIG. 2, the estimation system 100 in which the estimation device 20 estimates the installation position of the installation objects 10-1 to 10-3 as a plurality of installation objects 10 will be described as an example. However, the estimation system 100 may estimate the installation position of two or four or more installation objects 10.

The installation objects 10-1 to 10-3 have a function of receiving and transmitting radio waves. The installation objects 10-1 to 10-3 receive the radio waves transmitted by the other installation objects 10-1 to 10-3 excluding the own device. That is, the installation objects 10-2 and 10-3 receive the radio waves transmitted by the installation objects 10-1, respectively (step S1-1). The installation objects 10-1 and 10-3 receive the radio waves transmitted by the installation objects 10-2, respectively (step S1-2). The installation objects 10-1 and 10-2 receive the radio waves transmitted by the installation objects 10-3, respectively (steps S1-3). In order to avoid the influence of interference, the installation objects 10-1 to 10-3 transmit radio waves at different timings.

The estimation device 20 acquires information including the reception intensity of the radio waves received by the installation objects 10-1 to 10-3 from the installation objects 10-1 to 10-3, respectively (step S2). The radio waves transmitted by the installation objects 10-1 to 10-3 are attenuated until they are received by the other installation objects 10-1 to 10-3, and the intensity is lowered. For example, the reception intensity of radio waves varies depending on the propagation distance of radio waves, the shapes of floors 1 and spaces 2 to 4, the presence or absence of structures and obstacles arranged in floors 1 or spaces 2 to 4. Therefore, the estimation device 20 can estimate the installation position of the installation objects 10-1 to 10-3 based on the information including the reception intensity of the radio waves acquired from the installation objects 10-1 to 10-3, respectively.

The installation objects 10-1 to 10-3 may receive and transmit a plurality of radio waves having different frequencies. By transmitting and receiving a plurality of radio waves having different frequencies, the number of information including the reception strength is increased, so that the estimation accuracy of the installation position is improved. Specifically, the estimation device 20 acquires, for example, installation of the installation objects 10-1 to 10-3 by acquiring information including the reception intensity for each radio wave received by the installation objects 10-1 to 10-3. Position estimation accuracy is improved. Further, since the degree of reflection or absorption by the structure or obstacle differs depending on the frequency, it becomes easy to estimate the presence or absence of the structure or obstacle by transmitting and receiving a plurality of radio waves having different frequencies.

Further, the transmitting unit 12 may transmit a plurality of radio waves having different frequencies. The transmitting unit 12 has, for example, a plurality of channels in which transmission frequencies are registered, and the transmitting unit 12 can transmit radio waves having a frequency associated with the channels.

A control signal corresponding to the light source 152 is output to control the lighting state of the light source 152. Further, when a signal indicating a control instruction of a lighting instruction or an extinguishing instruction of the light source 152 is input from the controller by the operation of the controller (not shown) by the user, for example, the lighting control unit 151 causes the light source 152 to receive a control instruction. A control signal corresponding to a control instruction may be output to control the lighting state of the lighting unit 15.

The light source 152 is turned on or off in a manner corresponding to the control signal output from the illumination control unit 151. The light source 152 has, for example, a semiconductor light emitting element such as an LED (Light Emitting Diode). The light source 152 is not limited to the semiconductor light emitting element, and may be, for example, a fluorescent lamp or an incandescent lamp.

The "address" is a unique identifier individually assigned to each installation 10. The "address" may be, for example, an ID assigned to the lighting unit 15 of each installation object 10.

The "channel number" is an identification number for identifying a plurality of radio waves having different frequencies. In the example shown in FIG. 4, each installation 10 has four channels. The “radio wave reception intensity” corresponds to the radio wave reception intensity measured by the generation unit 134 for each address and channel number of each installation object 10. Specifically, for example, the radio wave information 141 shown in FIG. 4 receives a radio wave having a frequency corresponding to the channel number “1” from the installation object 10 to which the address “aaaaaa” is assigned, at an intensity of “-52 decibels”. It shows that it was done.

Further, the transmission unit 135 transmits radio wave information 141. The transmission unit 135 transmits the radio wave information 141 generated by the generation unit 134 to the estimation device 20. Further, when the receiving unit 131 receives the control signal requesting the transmission of the radio wave information 141, the transmitting unit 135 transmits the radio wave information 141 stored in the storage unit 14 to the estimation device 20. The transmission unit 135 superimposes information that identifies the transmission source, such as an address, on the radio wave information 141 and transmits the information.

In FIG. 7, the case where the estimation device 20 estimates the installation position of the installation objects 10-1 to 10-3 as in FIG. 2 will be described as an example.

As shown in FIG. 7, the reception unit 231 of the estimation device 20 requests the installation objects 10-1 to 10-3 to notify the address (step S11). When the reception unit 131 of the installation objects 10-1 to 10-3 receives the signal requesting the notification of the address, the transmission unit 135 of the installation objects 10-1 to 10-3 tells the estimation device 20 the address of its own device. (Step S12).

The reception unit 231 of the estimation device 20 notifies the installation objects 10-1 to 10-3 of the start of the estimation process (step S13). When the reception unit 131 of the installation objects 10-1 to 10-3 receives the control signal notifying the start of the estimation process, the transmission unit 12 of the installation objects 10-1 to 10-3 controls the transmission control unit 132, respectively. The corresponding radio wave is transmitted (step S14).

In step S13, the signal notifying the start of the estimation process may include information regarding the order in which the installation objects 10-1 to 10-3 transmit radio waves. For example, when the installation object 10-1 starts transmitting radio waves and ends transmitting radio waves after a predetermined time has elapsed by including the order in which radio waves are transmitted and the time for transmitting radio waves in the signal notifying the start of estimation processing. Next, the installation object 10-2 starts transmitting radio waves.

Further, in step S14, when the installation objects 10-1 to 10-3 transmit a plurality of radio waves having different frequencies, the channel number may be superimposed on the radio waves. Further, the order of transmitting radio waves may be determined in advance according to the channel number, and for example, the radio wave of channel number "1" may be transmitted for a predetermined time, and then the radio wave of channel number "2" may be transmitted for a predetermined time. As a result, the installation objects 10-1 to 10-3 can know which channel number the radio wave has received.

When the receiving unit 133 of the installation objects 10-1 to 10-3 receives the radio waves transmitted from the other installation objects 10-1 to 10-3 other than the own device, the generation unit 134 generates the radio wave information 141, respectively. (Step S15). The acquisition unit 232 of the estimation device 20 acquires the radio wave information 141 transmitted from the transmission units 135 of the installation objects 10-1 to 10-3, respectively (step S16).

The estimation unit 233 of the estimation device 20 estimates the set position of the installation objects 10-1 to 10-3 based on the radio wave information 141 (step S17). The display control unit 234 of the estimation device 20 displays the estimation result in which the radio wave information 141 and the estimated installation position of the installation objects 10-1 to 10-3 are associated with each other on the display unit 25 (step S18).

The reception unit 231 of the estimation device 20 operates the lighting control unit 151 via the reception unit 131 of the installation objects 10-1 to 10-3 in response to the confirmation operation input from the display screen 25a of the display unit 25. An operation check for turning on / off the light source 152 is executed (step S19).

The change unit 235 of the estimation device 20 changes the correspondence estimated by the estimation unit 233 according to the confirmation operation input from the display screen 25a of the display unit 25 (step S20). Further, the changing unit 235 confirms the estimated correspondence according to the confirmation operation input from the display screen 25a of the display unit 25 (step S21).

The generation unit 236 of the estimation device 20 generates model information 241 in which the radio wave information 141 and the installation position of the confirmed installation objects 10-1 to 10-3 are associated with each other (step S22), and stores the model information 241 in the storage unit 24. Let me.

The acquisition unit 232 acquires radio wave information 141 including the reception intensities of a plurality of radio waves having different frequencies received by the plurality of installation objects 10 from each of the plurality of installation objects 10. The estimation unit 233 estimates the installation positions of the plurality of installation objects 10 based on the radio wave information 141 acquired by the acquisition unit 232. As a result, the burden of setting work can be reduced.

FIG. 8 is a block diagram showing a configuration of an installation object according to a modified example of the embodiment. FIG. 9 is a block diagram showing a configuration of an estimation device according to a modified example of the embodiment.

As shown in FIG. 9, the installation position of the installation object 10A shown in FIG. 8 may be estimated by the estimation device 20A having the transmitting unit 22 that transmits radio waves. The transmitting unit 22 transmits radio waves in response to the control signal received by the receiving unit 231. For example, the transmitting unit 22 transmits radio waves in response to the control signal received by the receiving unit 231. When the transmitting unit 22 has a plurality of channels, the transmitting unit 22 changes the channels and transmits a plurality of radio waves having different frequencies set in advance. As a result, the installation object 10A shown in FIG. 8 does not require the transmission control unit 132 of the transmission unit 12 and the control unit 13. Therefore, the initial cost when introducing the plurality of installation objects 10A can be suppressed.

In the estimation device 20A, the transmitting unit 22 may transmit radio waves of the same frequency a plurality of times. In such a case, the position of the radio wave transmission source may be changed by moving the estimation device 20A which is the radio wave transmission source. By moving the estimation device 20A in this way to transmit radio waves a plurality of times, the estimation accuracy of the installation positions of the plurality of installation objects 10A is improved. Therefore, according to the modified example of the embodiment, the burden of the setting work in the estimation system 100 is reduced.

It may be realized. For example, the server may have at least a part of the control unit 23 and the storage unit 14 of the estimation devices 20 and 20A.

Further, in the above-described embodiment, the model information 241 has been described as being stored by the storage unit 24 of the estimation devices 20 and 20A, but for example, the storage unit 14 of the installation objects 10 and 10A may store the model information 241. Further, the storage units 14 and 24 may store the model information 241 respectively.

Further, in the above-described embodiment, the estimation device 20 has been described as acquiring the addresses of the installation objects 10 and 10A, but the present invention is not limited to this, and the address may not be acquired. Further, the installation objects 10 and 10A do not have to have an address. In such a case, the installation objects 10 and 10A may be specified by, for example, a model number, a model name, or the like.

Further, in the above-described embodiment, the arrangement position of the installation objects 10, 10A whose arrangement position is unknown is estimated, but the present invention is not limited to this, and the arrangement position of at least one installation object 10, 10A is known.
