Description

Number of people measurement system, mobile device and program

The present invention relates to grasping the number of people who are present in a space in which an occupancy measurement system, portable devices and programs, in particular, air conditioners are installed.

The heat generated from the person in the room or equipment used by the person in the room when the power is turned on, such as a PC or an OA device, may be a cause of fluctuations in the indoor thermal environment. In other words, the number of people in the room has a great influence on the indoor comfort. Conventionally, in order to make the indoor environment comfortable, a technique has been proposed in which air conditioning is controlled according to the number of people in the room (for example, Patent Documents 1 and 2).

JP 2001-201139 A Patent No. 4922001 Patent No. 6140214 Patent No. 5864297 Patent No. 4453679 Patent No. 5559519

When performing air conditioning control according to the number of people in the room, it is desirable to accurately grasp the number of people in the room. A remote control for operating an air conditioner is usually installed in each room of an office. Employees usually carry mobile devices such as smartphones. Alternatively, it is possible to provide a mobile device to carry. Therefore, it is conceivable that the remote controller is equipped with a short-range wireless communication function and the remote controller communicates with a portable device carried by a person in the room to grasp the number of people in the room.

However, it is not possible to accurately grasp the number of people in the room unless all mobile devices are present within the communicable range of the remote controller. In particular, the remote controller is generally installed near a wall near the entrance of a room. For this reason, the entire room does not always fall within the communicable range of the remote controller. That is, the remote controller may not be able to communicate with the mobile device carried by all the people in the room.

The purpose of the present invention is to make it possible to accurately grasp the number of people present in the space even if the entire space does not fall within the communicable range of the remote controller.

The presence measuring system according to the present invention is installed in a space in which an air conditioner is installed, and has a remote control of the air conditioner having a short-distance wireless communication function, and is carried by each user located in the space to perform short-distance wireless communication. A portable device having a function, and the remote controller is a device for collecting request number transmitting means for transmitting a device number collection delegation request, and a device number information returned from the portable device in response to the device number collection delegation request. When the portable device receives a unit number collection delegation request sent from the remote controller, the portable device operates as a representative device to send a response request and collects the number of units information. Representative device function processing means for returning device number information including device identification information of its own device in response to the delegation request and device identification information returned from the other portable device in response to the response request, and transmission from the remote controller In response to the response request transmitted from the other mobile device that operates as the representative device without receiving the requested number collection delegation request, the self device operates as a non-representative device in response to the response request. A non-representative device function processing means for returning device identification information of its own device, and an in-room number calculating means for calculating the number of people in the space based on the number-of-devices information collected by the number-of-devices information collecting means. It is a thing.

Further, the representative device function processing means collects a response request transmission unit that transmits a response request in response to the number-of-units collection delegation request, and device identification information returned from another portable device in response to the response request. Device identification information collection unit, and device number information that generates and returns device number information including the device identification information of its own device and the device identification information collected by the device identification information collection unit in response to the number collection delegation request And a reply section.

Further, the representative device function processing means, when the maximum number of relays is set in the number collection commission request, a route setting processing unit for transmitting a route setting request, and a predetermined time after receiving the unit collection commission request. A response request transmission unit for transmitting a response request after a lapse of time, a device identification information collection unit for collecting device identification information returned from the other portable device in response to the response request transmitted by the response request transmission unit, and A device number information reply unit for generating and returning device number information including the device identification information of the own device and the device identification information collected by the device identification information collecting unit in response to the number collection commission request. When the non-representative device function processing means receives a route setting request from another portable device, the non-representative device function processing means identifies the source of the received route setting request as a response destination to the response request, and the own device is the maximum from the representative device. If the position of the number of relays has not been reached, the own device is moved from the representative device to the position of the maximum number of relays in response to the route setting request handling processing unit that issues a route setting request and the response request received from the other portable device. If not, it sends a response request and returns the device identification information of its own device and the device identification information returned from the other portable device in response to the sent response request, and the own device relays the maximum from the representative device. If the number of positions is reached, a response request handling processing unit that returns the device identification information of its own device.

Further, when the plurality of route setting requests are received, the route setting request handling processing unit identifies the transmission source of the route setting request having a large number of relays from the representative device as a response destination to the response request.

Further, when a plurality of the remote controllers are provided in the air conditioner, it has a providing means for providing a common identification code to each of the remote controllers.

A portable device according to the present invention is a portable device carried by a user located in a space where an air conditioner and a remote controller of the air conditioner having a short-range wireless communication function are installed, and the number of devices collected from the remote controller is delegated. When a request is received, a response request is transmitted by operating the device itself as a representative device, and the device identification information of the device itself according to the number collection delegation request and another portable device according to the response request. Representative device function processing means for returning the number-of-devices information including the returned device identification information, and transmission from the other portable device that operates as the representative device without receiving the number-collection delegation request transmitted from the remote controller And a non-representative device function processing means for returning the device identification information of the self device in response to the response request by operating the self device as a non-representative device.

The program according to the present invention is transmitted from the remote controller to a computer installed in a portable device carried by a user located in a space where a remote controller of the air conditioner and a remote controller of the air conditioner having a short-range wireless communication function is installed. When receiving the number collection delegation request, a response request is transmitted by operating the own device as a representative device, and at the same time, the device identification information of the own device in response to the number collection delegation request and another response according to the response request. Representative device function processing means for returning device number information including device identification information returned from the portable device, and the other portable device that operates as the representative device without receiving a request for collecting number of devices delegating request from the remote controller. When a response request sent from a device is received, by operating the device as a non-representative device, the device functions as non-representative device function processing means for returning device identification information of the device in response to the response request. It is a thing.

According to the present invention, even if the entire space is out of the communicable range of the remote controller, it is possible to accurately grasp the number of people located in the entire space.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

Embodiment 1.
FIG. 1 is a diagram showing the overall configuration of the air conditioning system in the present embodiment. In FIG. 1, an air conditioner (an air conditioner is also referred to as an air conditioner or an air conditioner) 2 that is an air conditioner (hereinafter, referred to as an air conditioner) installed in a room 1 and a remote controller that operates the air conditioner 2 ( Hereinafter, a remote controller 3 which is a remote controller will be referred to as a remote controller) and a portable device 4 carried by a person in the room are shown. The remote controller 3 has a short-range wireless communication function and is fixedly installed on the wall near the doorway 5 of the room 1 where the air conditioner 2 is installed. In the present embodiment, it is assumed that the short-range wireless communication function is realized by BLE (Bluetooth (registered trademark) Low Energy) having a communicable range of about 5 to 10 m. In FIG. 1, the communicable range 6 of the remote controller 3 is indicated by a broken line.

The mobile device 4 is a mobile information device carried by a user such as a smartphone. The mobile device 4 has a short-range wireless function capable of communicating with the remote controller 3. In FIG. 1, the communicable range 7 of the portable device 4 carried by the person A in the room is indicated by a dashed line. The same portable device 4 is also carried by other persons in the room.

In addition, in the present embodiment, since only the users in the room 1 are targeted, “user” and “resident” are synonymous. In addition, it is assumed that the person in the room always carries the mobile device 4. In addition, when the mobile devices 4 are collectively referred to without distinction, they are described as “mobile device 4 ”. However, in the case of indicating the mobile device 4 carried by a specific user, for example, when the mobile device 4 carried by the “user A” is specified and described, the description will be given as “mobile device A”.

As shown in FIG. 1, the communicable range 6 of the remote controller 3 by short-range wireless communication does not cover the entire area of the room 1. Even if the remote controller 3 is a portable type and the remote controller 3 is carried to the center of the room 1, the communicable range 6 of the remote controller 3 carried to the center does not cover the entire area of the room 1. To do.

Each of the air conditioner 2, the remote controller 3, and the mobile device 4 has a built-in computer, and can be realized with a conventional general-purpose hardware configuration. That is, the air conditioner 2, the remote controller 3, and the portable device 4 (hereinafter, the air conditioner 2, the remote controller 3, and the portable device 4 are referred to as the respective devices 2, 3, and 4), which are the respective devices, include a CPU (Central Processing Unit), a ROM (Read It has at least an Only Memory) and a RAM (Random Access Memory). In the remote controller 3 and the mobile device 4, a communication interface for performing near field communication is an essential component. The air conditioner 2 is assumed to be connected to the remote controller 3 by wire. However, when the air conditioner 2 wirelessly communicates with the remote controller 3, the air conditioner 2 needs to have a communication interface for short-range wireless communication with the remote controller 3. Further, each of the devices 2, 3 and 4 may be separately provided with a storage means such as a storage for temporarily storing data to be communicated.

FIG. 2 is a block configuration diagram of the air conditioning system in the present embodiment. It should be noted that FIG. 2 shows components necessary for explaining the present embodiment. In FIG. 2, each of the devices 2, 3 and 4 has a constituent element that is originally provided for exhibiting its function but is not shown in the figure not used for explaining the present embodiment. ing. Further, when there are a plurality of mobile devices 4 in the room, each mobile device 4 needs to have the same configuration, so only one is shown in FIG. The same applies to the embodiments described later.

The air conditioner 2 has an air conditioning control unit 21 and a control table 22. The air conditioning control unit 21 performs air conditioning control according to the number of people in the room. The air conditioning control unit 21 in the present embodiment particularly performs air conditioning control according to the setting contents of the control table 22.

FIG. 3 is a diagram showing a data configuration example of the control table 22 in the present embodiment. In the control table 22, “elapsed time” and “control content” are associated with “number of people” and set. “Number of people” is the difference between the newly measured number of people in the room and the number of people in the room measured immediately before, that is, the number of people who have increased or decreased. The “control content” indicates the content of the air conditioning control when the number of persons is reached. The “elapsed time” is the elapsed time from when the difference in the number of people in the room is obtained to when the air conditioning control is started with the control content. The “control content” will be described together with the operation description.

The air conditioning control unit 21 is realized by the cooperative operation of the CPU mounted on the air conditioner 2 and the program operating on the CPU. Further, the control table 22 is realized by a storage unit such as a RAM mounted on the air conditioner 2.

The remote controller 3 in FIG. 2 has a communication unit 31, a collection delegation transmission unit 32, a device list collection unit 33, an in-occupancy number calculation unit 34, and a storage unit 35. The communication unit 31 is realized by a communication interface equipped with a short-range wireless communication function, and performs short-range wireless communication with the mobile device 4. The collection delegation transmitting unit 32 periodically transmits a collection delegation (corresponding to a “unit number collection delegation request”) to the mobile device 4. The device list collection unit 33 collects a device list (corresponding to “device number information”) returned from the mobile device 4 in response to the delegation of collection. The occupancy calculation section 34 measures the number of users in the room 1, that is, the occupancy based on the device list collected by the device list collection section 33. The storage unit 35 stores the device list transmitted from the mobile device 4.

The components 31 to 34 in FIG. 2 are realized by the cooperative operation of the CPU mounted on the remote controller 3 and the program running on the CPU. The storage unit 35 is realized by a storage unit such as a RAM mounted on the remote controller 3.

The mobile device 4 in FIG. 2 has a communication unit 41, a representative device function processing unit 42, a non-representative device function processing unit 43, a control unit 44, and a storage unit 45. The communication unit 41 is realized by a communication interface equipped with a short-range wireless communication function, and performs short-range wireless communication with the remote controller 3 and another mobile device 4. The representative device function processing unit 42 realizes a processing function when the own device operates as a representative device. In contrast to the representative device function processing unit 42, the non-representative device function processing unit 43 realizes a processing function when the own device does not operate as the representative device.

Here, the “representative device” is the portable device 4 located within a range where short-distance wireless communication can be performed with the remote controller 3, and receives the data transmitted by the remote controller 3, that is, the data of the collection delegation in the present embodiment. The portable device 4 that operates. In other words, by receiving the collection delegation, the mobile device 4 that has received the collection delegation is placed in the position of the representative device. For example, in FIG. 1, the mobile devices A, B, and C located within the communicable range 6 of the remote controller 3 correspond to representative devices. The mobile devices 4 other than the mobile devices A, B, and C are not representative devices. Further, in the present embodiment, another portable device 4 located near the own device (a certain portable device 4) and in a range communicable with the own device is referred to as a “neighboring device”. For example, in FIG. 1, the mobile devices B, C, D, and E located within the communicable range 7 of the mobile device A are neighboring devices of the mobile device A. In the mobile devices B, C, D, and E, the mobile devices 4 located in their respective communicable ranges are neighboring devices.

The portable device 4 is located within the communicable range 6 of the remote controller 3 and causes the representative device function processing unit 42 to perform processing when receiving the collection delegation transmitted from the remote controller 3. That is, the mobile device 4 operates its own device as a representative device. The representative device function processing unit 42 in this embodiment has a response request transmission unit 421, a device ID collection unit 422, and a device list transmission unit 423. The response request transmission unit 421 transmits a response request (corresponding to “response request”) to the other mobile device 4 according to the collection delegation. The device ID collection unit 422 collects the device IDs returned from the other mobile devices 4 (corresponding to the above “neighboring device”) in response to the response request, and stores the device IDs in the storage unit 45. The device ID is device identification information unique to each mobile device 4, and is, for example, an IP address (Internet Protocol Address) or the like. The device list transmission unit 423 generates a device list including the device ID of its own device and the device ID collected by the device ID collection unit 422 according to the collection delegation, and sends it back to the remote controller 3.

If the mobile device 4 is not located within the communicable range 6 of the remote controller 3, the mobile device 4 does not receive the collection delegation transmitted from the remote controller 3. However, when the response request transmitted from the representative device is received, the non-representative device function processing unit 43 is caused to perform processing. That is, the mobile device 4 that has received the response request operates its own device as a device other than the representative device (non-representative device). The non-representative device function processing unit 43 in the present embodiment has a device ID transmission unit 431 that returns the device ID of its own device in response to a response request.

The control unit 44 is responsible for a part of the process of measuring the number of people in the room in cooperation with other components such as the operation control of the representative device function processing unit 42 and the non-representative device function processing unit 43 described above. The storage unit 45 stores the device ID transmitted from the other mobile device 4 when measuring the number of people in the room.

Each of the constituent elements 41 to 44 of the mobile device 4 is realized by the cooperative operation of the CPU mounted on the mobile device 4 and the program operating on the CPU. Further, the storage unit 45 is realized by a storage unit such as a RAM mounted on the mobile device 4.

The program used in the present embodiment can be provided not only by communication means but also by being stored in a computer-readable recording medium such as a USB memory. The program provided from the communication unit or the recording medium is installed in the computer, and the CPU of the computer sequentially executes the program to realize various processes.

FIG. 4 is a diagram showing a data configuration example exchanged between the remote controller 3 and the mobile device (representative device) 4 and between the mobile devices 4 in the present embodiment. In FIG. 4, a code for identifying the type of data to be transmitted/received is set in the communication type. In the present embodiment, the collection delegation is periodically sent by the remote controller 3, and the time ID is set to an identifier capable of specifying the time when the collection delegation was sent. Based on the time ID, it is possible to discriminate between a collection commission and another collection commission. The remote controller ID is set to the identifier of the remote controller 3 that has transmitted the collection delegation. The identifier of the mobile device 4 that transmits the data is set in the device ID. The number of hops will be described in an embodiment described later.

As mentioned above, the short-range wireless communicable range 6 of the remote controller does not necessarily cover the entire area of the room 1. Therefore, there is no guarantee that the remote controller 3 alone can accurately measure the person in the room 1. On the other hand, in recent years, most people have a portable device 4 such as a smartphone or a tablet terminal. Some companies provide the mobile device 4 to all employees. The mobile device 4 is equipped with a short-range wireless communication function as a standard feature. In addition to BLE as a short-range wireless communication function, the mobile device 4 is equipped with Wi-Fi (registered trademark) (Wireless Fidelity) having a communicable range of about 100 m. In the present embodiment, it is assumed that the portable device 4 is always carried when a person in the room moves in the building. In addition, the number of mobile devices 4 detected in the room 1 is regarded as the number of people in the room to perform measurement. Further, the present embodiment is characterized in that the remote controller 3 installed in the room 1 delegates to the mobile device 4 to detect the number of the mobile devices 4 in the room 1.

Next, the number-of-people measurement process in the present embodiment will be described using the flowcharts shown in FIGS. 5 to 7.

In FIG. 5, the remote controller 3 executes the process shown in FIG. 5 by activating a predetermined application at regular intervals. First, when the application is activated, the collection delegation transmission unit 32 broadcasts (sends) the collection delegation via the communication unit 31 (step 301). The collection delegation is generated according to the data structure shown in FIG. More specifically, a code (CR) indicating collection authorization is set in the communication type. A code (identifier) generated based on the current time is set in the time ID. The identifier of the own device is set in the remote control ID. Other items may be blank. The remote controller 3 sets a timer for the first predetermined period after transmitting the collection delegation. As the first predetermined period, for example, a timer of 1 minute is set, and the process proceeds to the process of receiving the device list so that the device list is received from the portable device 4, that is, the representative device in 1 minute.

The user needs to activate a predetermined application of the mobile device 4 at least when he/she is in the room so that the processing shown in FIG. 6 can be executed at all times.

In FIG. 6, when the application is activated, the mobile device 4 enters a data reception waiting state (N in step 401). When the data is received via the communication unit 41 in Step 401 (Y in Step 401), the control unit 44, if the received data is the collection delegation transmitted from the remote controller 3 (Y in Step 402), the representative The device function processing unit 42 is operated. Then, the response request transmission unit 421 in the representative device function processing unit 42 broadcasts (transmits) a response request via the communication unit 41 (step 403). The response request is generated by the response request transmission unit 421 according to the data structure shown in FIG. More specifically, the response request transmission unit 421 sets a code (AR) indicating a response request in the communication type. Further, the time ID set in the collection delegation is set in the time ID. Further, the remote controller ID is set to the remote controller ID set for collection delegation. Further, the device ID is set to the identifier of the device itself. Other items may be blank. By setting the item data set in the collection delegation to the time ID and the remote control ID, it is possible to specify from which remote control 3 which data is transmitted and received according to the collection delegation. After transmitting the response request, the representative device function processing unit 42 sets a timer for the second predetermined period, for example, a timer for 30 seconds as the second predetermined period, and the other portable device 4, that is, the neighbor, for 30 seconds. The process moves to the process of receiving the response so as to receive the response (device ID) from the device. The second predetermined period is preferably set to a time shorter than the first predetermined period described above.

As described above, when the application is activated, the mobile device 4 enters a data reception waiting state (N in step 401). Here, when data is received via the communication unit 41 (Y in step 401) and the received data is a response request transmitted from another mobile device 4, that is, the representative device (N in step 402), control is performed. The unit 44 operates the non-representative device function processing unit 43 in order to operate the own device as a neighboring device of the representative device and as a non-representative device. Then, the device ID transmission unit 431 in the non-representative device function processing unit 43 responds to the response request (step 408). This response is generated according to the data structure shown in FIG. More specifically, a code (ACK) indicating a response is set for the communication type. The time ID set in the response request is set in the time ID. The remote control ID set in the response request is set in the remote control ID. The device ID is set to the identifier of the device itself (device ID). Other items may be blank. By setting the item data set in the response request to the time ID and the remote controller ID, it is possible to specify from which remote controller 3 which data is transmitted and received according to the collection commission.

The mobile device 4, which is a representative device, is in the process of receiving a response (device ID) from a neighboring device for a second predetermined period by setting a timer. Upon receiving the response from the neighboring device (step 404), the device ID collection unit 422 of the mobile device 4 corresponding to the representative device stores the received response in the storage unit 45 (step 405). Then, if the response waiting time (“second predetermined period” above) has not elapsed (N in step 406), a waiting state for receiving a response from a neighboring device other than the neighboring device that received the response in step 404. (Step 404). Then, when the response waiting time elapses (Y in step 406), the device list transmission unit 423 reads the device ID stored in the storage unit 45 and generates a device list together with the device ID of its own device. The device list transmission unit 423 transmits the generated device list to the remote controller 3 (step 407). It should be noted that the device list transmission unit 423 refers to the time ID included in the response in order to more reliably generate the device list corresponding to one collection delegation, and the device list transmission unit 423 includes the same time ID in the response. You may process so that the apparatus ID which exists may be read.

In this way, the representative device collects the device ID from the neighboring device according to the collection delegation from the remote controller 3. Then, the collected device ID includes the device ID of its own device, and returns the request to the remote controller 3 as the request source.

The representative device function processing unit 42 performs the time counting process in the portable device 4 asynchronously with the process of collecting the device ID, and cancels the reception waiting state when the response waiting time has elapsed even in the reception waiting state in step 404. Then, it is necessary to shift to step 407.

The device list is generated according to the format shown in FIG. More specifically, a code (RR) indicating a delegation response is set in the communication type. The time ID set in the collection delegation is set in the time ID. The remote control ID set to the collection delegation is set to the remote control ID. The identifier of the device itself is set in the device ID. Then, the device list is set in the other items.

As shown in FIG. 5, the remote controller 3 shifts to a process of receiving a device list from a representative device for a first predetermined period by setting a timer. When the remote controller 3 receives the device list from the representative device (step 302), the device list collection unit 33 stores the received device list in the storage unit 35 (step 303). Then, if the collection time (the above-mentioned “first predetermined period”) has not elapsed (N in step 304), the process returns to the state of waiting for the reception of the device list from other representative devices (step 302). Then, when the collection time has elapsed (Y in step 304), the process proceeds to the process of grasping the number of people in the room by the number of people in room calculation unit 34 (step 305). In the remote controller 3, it is necessary to perform the time counting process asynchronously with the device list collecting process, cancel the reception waiting state and move to step 305 even if the collection waiting time has elapsed in the reception waiting state in step 302.

When the remote controller 3 collects the device list from the representative devices, the in-room number calculating unit 34 totals the device list and grasps the number of people in the room (step 305). When there is one representative device, the number of device IDs included in the device list collected from the representative device is the number of people in the room. When the device list is collected from a plurality of representative devices, the mobile device 4 may be redundantly detected. For example, according to FIG. 1, the mobile device B is a representative device, but since it is also a neighboring device of the mobile device A, the device IDs of the mobile device B are redundantly collected. Therefore, the occupancy calculation unit 34 compares the device IDs collected from the representative devices, and totals the device IDs so that the same mobile device 4 is not counted twice. Then, since the total number of device IDs is the number of people in the room 1, the total number of people in the room is transmitted to the air conditioner 2. The number of people present in the room is reported by transmitting the number of people present in the air conditioner 2 (step 306).

When the operation of the air conditioner 2 is started, a predetermined application is activated so that the air conditioning control unit 21 can always perform processing.

When the application is activated, the air conditioning control unit 21 of the air conditioner 2 waits for reception of the number of people in the room from the remote controller 3 as shown in FIG. 7 (N in step 201). Here, when the air-conditioning control unit 21 receives the number of people in the room by the report from the remote controller 3 (Y in step 201), if the number of people in the room received is not 0, that is, if there is a person in the room (step 202). N), the number of people in the room received this time is compared with the number of people in the room received and stored in the immediately preceding process. The air-conditioning control unit 21 calculates the increased/decreased number of people in the room by comparing the number of people (step 203). Then, the air-conditioning control unit 21 controls the air-conditioning according to the number of people in the room according to the setting contents of the control table 22 (step 204).

For example, when the number of persons in the room is increased by one, the air conditioning control unit 21 refers to the setting of “+1” in the control table 22 shown in FIG. 3 and increases the driving capacity at the present time by 10% for 60 seconds. Let me drive. In this way, the comfort level inside the room temporarily deteriorates as the number of people in the room increases. For example, in summer, the room temperature is expected to rise, so the cooling capacity is automatically increased. Further, for example, when the number of persons in the room decreases by two, the driving capacity is reduced by 15% for 90 seconds from the current driving capacity by referring to the setting of "-2" in the control table 22 shown in FIG. As described above, since the number of people in the room decreases, continuous operation with the current driving capacity may result in excessive driving, so that it is possible to obtain an energy saving effect by suppressing the driving capacity.

Note that the numerical example of the control table 22 shown in FIG. 3 is an example, and may be set as appropriate according to the size of the room 1, the performance of the air conditioner 2, and the like. Further, instead of simply increasing or decreasing the number of people in the room, the number of people in the room at the present time may be referred to and set in the control table 22 in detail according to the number of people in the room.

The air-conditioning control unit 21 performs air-conditioning control as described above and stores the number of people in the room received this time internally so that it can be compared with the number of people in the room to be received next time (step 205). Of course, if the history of the number of people in the room is to be recorded, it may be recorded in the storage means (not shown).

On the other hand, when the number of people in the room is 0, that is, when there is no user in the room 1 (Y in step 202), the air conditioning control unit 21 controls the air conditioning according to the setting contents of the control table 22. According to the setting example of the control table 22 of FIG. 3, when the number of persons in the room is 0, the air conditioning control unit 21 stops the operation of the air conditioner 2 after 30 seconds (step 206). In this way, by performing the air conditioning control based on the number of people in the room, the air conditioner 2 can be automatically stopped when there are no more people in the room. Since the air conditioner 2 can be automatically stopped, useless power consumption can be suppressed and the energy saving effect can be improved even when the last person who forgets to turn it off.

In this embodiment, the control table 22 is not set when the number of people in the room does not change. That is, when the number of people in the room does not change, the air conditioning control unit 21 does not perform the air conditioning control based on the number of people present in the room, but performs the air conditioning control based on the existing setting.

According to the present embodiment, since the grasp of the number of persons in the room is delegated to the portable device 4 carried by the person in the room, the short-range wireless communicable range 6 of the remote controller 3 cannot cover the entire area of the room 1. However, the number of people in the room can be accurately measured.

Note that the user may carry a plurality of mobile devices 4. In this case, the duplicated person count may be avoided by restricting the application program to be installed in only one mobile device 4 for each user.

Also, in the present embodiment, the number of people in the room is measured periodically. Therefore, the time ID is set to the data to be transmitted/received so as not to be confused with other measurements, especially the measurements performed before and after. In addition, the time when the measurement is performed can be specified by using the time. However, in order to identify one measurement, a unique character string or the like may be generated and used instead of the time.

Embodiment 2.
In the first embodiment, the room for which the number of people in the room is to be measured is assumed to be an office room or a conference room where employees are engaged. However, in a space such as a hall or a gymnasium where the number of people in the room is very wide, or when the mobile device 4 uses only BLE as a short-range wireless communication function (that is, the communicable range is relative to the space It is possible to assume that the entire area of the room 1 cannot be included in the communicable range only with the remote controller 3 and the representative device (for example, in the case of a relatively narrow space). Therefore, in the present embodiment, the number of people in the room can be measured in cooperation with the mobile device 4 so that it can be applied to a large space.

FIG. 8 is a block configuration diagram of the air conditioning system in the present embodiment. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted as appropriate. The present embodiment differs from the first embodiment in that a plurality of remote controllers 3 are connected to the air conditioner 2 and the time server 10 is provided in terms of system configuration.

As described in the first embodiment, the time ID included in the data exchanged between the devices 3 and 4 is generated using the time set in the remote controller 3. When there are a plurality of remote controllers 3 as in the present embodiment, different time IDs may be generated unless the times on the respective remote controllers 3 are completely the same. Then, if the device IDs collected at one measurement of the number of people in the room are not collected at the same timing, there is a possibility that the device IDs may be mistakenly recognized. Therefore, in this embodiment, since the time server 10 is provided, each remote controller 3 can use a common time.

Although the time server 10 is provided in the present embodiment, any one remote controller 3 notifies the other remote controller 3 of its own time so that each remote controller 3 uses the same time for time ID generation. It may be configured as follows. In addition, the time is used to discriminate one measurement, in other words, to prevent it from being mixed with other measurements (particularly, the preceding and succeeding measurements). A means for generating may be used.

The air conditioner 2 has the configuration of the first embodiment, and in the first embodiment, has the occupant number calculation unit 23 provided in the remote controller 3. The remote controller 3 is provided with a device list transmission unit 36 for passing the collected device list to the air conditioner 2 when the processing function of the occupancy calculation unit 34 is moved to the air conditioner 2.

The components of the mobile device 4 are the same as those of the first embodiment, but the internal configurations of the representative device function processing unit 42 and the non-representative device function processing unit 43 are different. The representative device function processing unit 42 has a configuration in which a test request transmission unit 424 is added to the configuration of the first embodiment. The test request transmission unit 424 transmits a test request (corresponding to “route setting request”) when the maximum number of relays is set in the received collection delegation. The “maximum number of relays” is the number of mobile devices 4 that relay data (“test request” described later) from the device (representative device) that is the starting point. The non-representative device function processing unit 43 includes a test request response processing unit 432 and a response request response processing unit 433. When the test request response processing unit 432 receives a test request from another mobile device 4, the test request response processing unit 432 identifies the transmission source of the received test request as the response destination for the response request received after the reception of the test request. In addition, if the own device does not reach the position of the maximum number of relays from the representative device, in other words, the number of reception hops of the collection delegation received, the test request is transmitted. Here, the “position of the maximum number of relays” means the number of the mobile devices 4 scattered in the position farther from the representative device and in the position where the device ID can be collected. That is. In response to the response request received from the other mobile device 4, the response request handling processing unit 433 sends a response request unless the own device has reached the maximum number of relay positions from the representative device. In addition, the device ID of the own device and the device ID returned from the other mobile device 4 in response to the transmitted response request are returned. If the own device has reached the position of the maximum number of relays from the representative device, the device ID of the own device is returned. The response request handling processing unit 433 has the same function as the device ID transmission unit 431 of the first embodiment in that the device ID of the own device is returned in response to the response request.

Next, the measurement process of the number of people in the room in the present embodiment will be described. The description of the same processes as those in the first embodiment will be appropriately omitted.

In the first embodiment, the remote controller 3 starts processing when a predetermined application is activated and broadcasts the collection delegation. In the present embodiment, the flowchart shown in FIG. 5 is executed with the notification of the time from the time server 10 as a trigger. Therefore, the remote controller 3 starts operating when a predetermined application is activated, and is in a waiting state for receiving the time from the time server 10. Since the time server 10 periodically transmits the time to each remote controller 3, the collection delegation transmitting unit 32 in each remote controller 3 sends the time ID included in the collection delegation to the time sent from the time server 10. Based on. Therefore, each remote controller 3 generates the same time ID, and one measurement can be specified. Note that all the remote controllers 3 execute the same processing.

Further, the collection delegation transmitting unit 32 in the present embodiment sets the number of hops (see FIG. 4) for the collection delegation, but sets the above-mentioned maximum number of relays as the number of hops. The maximum number of relays may be different depending on the remote controller 3. As described above, the remote controller 3 generates and transmits the data of the collection commission. After issuing the collection delegation, a timer for 1 minute, for example, is set as the first predetermined period, and the process proceeds to the process of receiving the device list so as to receive the device list from the portable device 4, that is, the representative device, in 1 minute.

Upon receiving the collection delegation, the mobile device 4 in the present embodiment collects the device ID of the mobile device 4 in a two-step process. Characteristic processing in this embodiment will be described with reference to the flowcharts shown in FIGS. The same processes as those in the first embodiment are given the same step numbers, and description thereof will be omitted as appropriate.

As shown in FIG. 9, when the application is activated, the mobile device 4 sets the number of hops internally stored in the mobile device 4 (hereinafter, “stored hop number”) to 0 and sets the response destination to the response request. Initialized to unset (step 421). Then, although a data reception waiting state is set (N in step 401), when data is received (Y in step 401), the process branches depending on the type of the received data.

Here, the process of the first stage, that is, the process of determining the collection route of the device ID will be described.

In FIG. 9, first, when the received data is a collection delegation (“collection delegation” in step 402), the control unit 44 operates the representative device function processing unit 42. Then, the test request transmission unit 424 in the representative device function processing unit 42 broadcasts (transmits) the test request via the communication unit 41 as the first stage processing (step 422). The test request is generated according to the data structure shown in FIG. More specifically, a code (ER) indicating a test request is set for the communication type. Each item data set for collection delegation is set to the time ID, remote control ID, and hop count. The identifier of the device itself is set in the device ID. Other items may be blank. By setting the item data set in the collection delegation to the time ID and the remote control ID, it is possible to specify from which remote control 3 which data is transmitted and received according to the collection delegation. After the test request is transmitted, a timer is set to wait for a third predetermined period, that is, the time required to determine the collection route, for example, 15 seconds, and then the process proceeds to the second stage.

In the mobile device 4, when the received data is a test request (“test request” in step 402), the control unit 44 operates the non-representative device function processing unit 43. Then, the test request handling processing unit 432 in the non-representative device function processing unit 43 subtracts 1 from the number of hops set in the received test request (hereinafter, “reception hop number”) (step 434). Subsequently, the test request handling unit 432 compares the number of received hops with the number of hops stored therein (hereinafter, “stored hop number”). The number of stored hops at this point is the number of hops initialized in step 421. If the number of received hops is larger than the number of stored hops (Y in step 424), the device ID of the portable device 4 that is the transmission source of the received test request is stored in the response destination (initially in step 421). (Step 425). If the response destination has already been set, the response destination will be changed. If the number of received hops is less than or equal to the number of stored hops (N in step 424), the process moves to step 426. That is, in this processing, the device ID of the mobile device 4 that has transmitted a large number of hops is held as the response destination of the response request.

Subsequently, when the number of reception hops set in the received test request is 1 or more (Y in step 426), the stored hop number is updated with the number of reception hops (step 427), and the test request is broadcast (transmitted). (Step 428). As described above, in the present embodiment, the mobile device 4 that has received the test request transmitted from the other mobile device 4 itself transmits the test request is called “relay”.

For the test request, set a code (ER) indicating the test request for the communication type. Each item data set in the received test request is set in the time ID and the remote control ID. The identifier of the device itself is set in the device ID. The stored hop count updated in step 427 is set in the hop count. Other items may be blank. In this way, the portable device 4 that has received the test request holds the stored hop count and the response destination internally, and broadcasts the test request until the hop count becomes 0, thereby receiving the test request from the representative device. It will be relayed.

Note that the representative device may also receive the test request sent by the neighboring device. However, for example, the fact that the device itself has become the representative device is held internally so that it does not respond to a test request from a neighboring device.

Mobile device 4 (non-representative device) other than the representative device may receive the test request from other mobile devices 4 multiple times. However, the response destination, which is the destination corresponding to the response request described later, is limited to the single portable device 4 held in step 425. Further, when the number of received hops is larger than the number of stored hops, changing the response destination to the response request enables the self device to relay the device IDs of more mobile devices 4. That is, it becomes possible to collect the device IDs of the portable devices 4 scattered in a range farther from the representative device.

The mobile device 4 located away from the representative device receives the test request including the subtracted hop number, and the test request is relayed, so that the test request having the hop number of 1 (reception hop in step 434). The mobile device 4 that receives the test request (the number of which is 0) appears. When the number of received hops becomes 0 (N in step 426), the test request is not relayed. At this time, in the mobile device 4 which has received the test request for the first time, since the response destination remains unset, the device ID of the mobile device of the test request transmission source is set as the response destination (step 429). In this way, the portable device 4 corresponding to the response request is set as the response destination of the non-representative device, and the collection route of the device ID is determined.

In the first stage processing, the route for collecting the device ID can be determined as described above. Although the representative device exists at the highest position on the route, in the following description, the portable device 4 at the end position on the route will be referred to as a “terminal device”. Although there can be 0 to 3 mobile devices 4 between the representative device and the terminal device, the mobile device 4 located between the representative device and the terminal device is referred to as an "intermediate device". I will decide.

Next, the second stage processing will be explained. The process of the second stage is a process of collecting the device IDs of the mobile devices in the room 1 described in the first embodiment.

When the third predetermined period has elapsed, the response request transmission unit 421 in the representative device function processing unit 42 executes a device ID collection process as shown in FIG. 9 to request a response (step 423). The device ID collection process is basically the same as the process (steps 403 to 407) described in the first embodiment. That is, the response request transmission unit 421 broadcasts (transmits) a response request via the communication unit 41, as shown in FIG. 10 (step 451). The response request may be the same as in the first embodiment. The number of hops set in the response request is used in the first stage process and is not necessary in the second stage process. After transmitting the response request, a timer is set as a second predetermined period, for example, for 30 seconds, and the response is received so that the response (device ID) is received from another portable device 4, that is, a neighboring device in 30 seconds. Move to processing. The second predetermined period is a time shorter than the first predetermined period described above.

Next, as shown in FIG. 9, when the received data is a response request (“response request” in step 402), the response request handling processing unit 433 in the non-representative device function processing unit 43 determines the sender of the response request. Check. If the source of the response request does not match the internally stored response destination (N in step 430), the mobile device 4 has received the response request from the mobile device 4 that is not in the device ID collection path. , Without returning to the received response request, returns to the waiting state for receiving the next data (step 401).

On the other hand, when the transmission source of the response request matches the internally stored response destination (Y in step 430), the response request handling processing unit 433 confirms the stored hop count stored internally, and determines the hop count. Is not 1 or more, that is, when the number of stored hops is 0 (N in step 431), the own device can be determined to be the mobile device 4 at the end on the route, that is, the end device. Therefore, the response request handling unit 433 responds to the response request (step 433). That is, the device ID of its own device is returned in response to the response request.

On the other hand, when the number of stored hops is 1 or more (Y in step 431), the self device can be determined to be the mobile device 4 on the way on the route, that is, the intermediate device. Therefore, the response request handling processing unit 433 executes the device ID collection processing in response to the response request (step 432). The device ID collection process is basically the same as the process described in the first embodiment. That is, the response request handling unit 433 broadcasts (transmits) a response request via the communication unit 41, as shown in FIG. 10 (step 451). The response request may be the same as in the first embodiment. The number of hops set in the response request is used in the process of the first stage and is not necessary in the process of the second stage. After the response request is sent, a timer for 20 seconds, for example, is set as the fourth predetermined period, and the process proceeds to receive a response so that a response (device ID) is received from another portable device 4 for 20 seconds. .. The fourth predetermined period is preferably set to a time shorter than the second predetermined period set by the representative device for collecting the device ID.

In step 452, the mobile device 4 (representative device or intermediate device, which is assumed here to be an intermediate device) waiting for a response from the other mobile device 4 is The device ID of the portable device 4 is received from the terminal device (step 452). If the other mobile device 4 is an intermediate device, the device list is received. When a response from another mobile device 4 is received, the device ID included in the response (or the device ID included in the device list) is stored in the storage unit 45 (step 453).

If the response waiting time (the “fourth predetermined period” above) has not elapsed (N in step 454), the process returns to the waiting state for receiving a response from the other mobile device 4 (step 452). Then, when the response waiting time has elapsed (Y in step 454), the response request handling processing unit 433 reads the device ID stored in the storage unit 45 and generates a device list together with the device ID of the self device. , And transmits to the mobile device 4 of the higher rank (step 455). The high-order mobile device 4 is the representative device or the mobile device 4 (intermediate device) that is the source of the response request.

The mobile device 4, which is a representative device, is in the process of receiving a response (device ID) from a neighboring device for a second predetermined period by setting a timer. Upon receiving the response from the neighboring device (step 452), the portable device 4 corresponding to the representative device stores the device ID (or the device list) included in the response in the storage unit 45 (step 453). If the response waiting time (the “second predetermined period” above) has not elapsed (N in step 454), the process returns to the state of waiting for a response from another neighboring device (step 452). Then, when the response waiting time elapses (Y in step 454), the device list transmission unit 423 reads the device ID stored in the storage unit 45, generates a device list together with the device ID of its own device, and performs remote control. 3 (step 455).

The remote controller 3 shifts to the process of receiving the device list from the representative device for the first predetermined period by setting the timer. When the remote controller 3 receives the device list from the representative device, the collection/delegation transmitting unit 32 stores the received device list in the storage unit 35 as shown in FIG. 5 (step 303). Then, if the collection time (the above-mentioned “first predetermined period”) has not elapsed (N in step 304), the process returns to the state of waiting for the reception of the device list from other representative devices (step 302). When the collection time has elapsed (Y in step 304), the air conditioner 2 is notified of the device list (device ID) stored in the storage unit 35 with the time ID added.

Since the remote controller 3 connected to the air conditioner 2 operates as described above, the air conditioner 2 receives the device list from each remote controller 3 after the collection time has elapsed. Thereby, the occupancy calculation unit 23 takes out the device IDs from the device list to which the same time ID is added, and totals the same device IDs so as not to be counted twice. The number of device IDs thus obtained is the number of people in the room 1.

When the number of people present in the room can be measured, the air conditioner 2 performs air conditioning control according to the setting contents of the control table 22 as in the first embodiment.

As described above, according to the present embodiment, even when a plurality of remote controllers 3 are connected to the air conditioner 2, it is possible to accurately measure the number of people in the room at each measurement time point.

Note that when a plurality of air conditioners 2 are installed in the room 1, it can be realized by combining a plurality of configurations described in the first embodiment. However, in this case, a server or the like above the air conditioner 2 collects the device list from each air conditioner 2 or the remote controller 3 connected to each air conditioner 2 and duplicates the same device ID included in the collected device list. It is necessary to add up so as not to count.
