The installation position information is information indicating an installation position where each sensor 1 is installed. The installation position information may be three-dimensional coordinates as long as it can identify the installation position of each sensor 1, or may be information indicated by a unique expression method in the air conditioning control target space. The installation position information of the sensor 1 is stored in the controller 2 by the user, for example, when the air conditioning control system 100 is constructed.

The operation unit 42 receives an operation from the user. The operation unit 42 receives, for example, an operation of starting or stopping reception of a wireless packet from a user. The operation unit 42 may be realized by a touch panel or the like together with the display unit 45.

The calculation unit 43 filters the wireless packet received from the sensor 1 and calculates the communication path, relay frequency, and the like of the wireless packet. Specifically, the calculation unit 43 uses the identification information of the source sensor and the relay sensor included in the wireless packet received by the communication unit 44 to relay the communication path of the wireless packet and the wireless packet between the sensors 1.

The sensor 1 may perform the operation of measuring the environmental state and transmitting the wireless packet when the controller 2 controls the air conditioning operation of the air conditioner 3. Therefore, the sensor 1 may start the operation of measuring the environmental state and transmitting the wireless packet when receiving an instruction from the controller 2. Note that the sensor 1 may perform an operation of measuring an environmental state and transmitting a wireless packet regardless of the presence or absence of an instruction from the controller 2.

FIG. 8 is a flowchart showing the operation of the controller 2 according to the first embodiment. In the controller 2, the communication unit 23 receives the wireless packet from the sensor 1 (step S31). The control unit 22 controls the air conditioning operation of the air conditioner 3 by using the installation position information of each sensor 1 stored in the storage unit 21 and the measured value included in the wireless packet (step S32).

FIG. 9 is a flowchart showing the operation of the terminal device 4 according to the first embodiment. In the terminal device 4, the operation unit 42 receives the start of scanning the wireless packet, that is, the start of receiving the wireless packet from the user (step S41). It is assumed that the operation unit 42 has a button or the like that can accept the reception start or reception stop of the wireless packet from the user. The operation unit 42 notifies the calculation unit 43 that the operation for starting reception of the wireless packet has been accepted from the user. The communication unit 44 starts communication with the sensor 1 under the control of the calculation unit 43 (step S42). At this time, the terminal device 4 connects to one of the plurality of sensors 1 included in the air conditioning control system 100 and communicates with the sensor 1.

The communication unit 44 receives the wireless packet transmitted by the sensor 1 from the connected sensor 1 (step S43). The calculation unit 43 calculates the communication path of the radio packet and the relay frequency of the radio packet between the sensors 1 by using the identification information of the source sensor and the relay sensor included in the radio packet received by the communication unit 44.

When the user has not received the stop of scanning the wireless packet, that is, the stop of receiving the wireless packet (step S46: No), the terminal device 4 returns to step S43 and repeats the above operation. When the user accepts the stop of scanning the wireless packet, that is, the stop of receiving the wireless packet (step S46: Yes), the terminal device 4 ends the operation.

FIG. 10 is a diagram showing an example of the installation position of each sensor 1 on the floor map, the communication path of the wireless packet, and the relay frequency of the wireless packet displayed on the display unit 45 of the terminal device 4 according to the first embodiment. Is. FIG. 10 shows a display example displayed by the display unit 45 in step S45 of the flowchart shown in FIG. In FIG. 10, for the sake of brevity, six sensors 1 out of the plurality of sensors 1 are displayed as IDs 0 to ID5 which are identification information of each sensor 1. Further, FIG. 10 shows an example in which the terminal device 4 connects the wireless packet transmitted from the sensor 1 having the identification information of ID0 to the sensor 1 having the identification information of ID5 and receives it.

As shown in FIG. 10, the display unit 45 displays the installation position of the sensor 1 on the floor map. In FIG. 10, the sensor 1 that relays the wireless packet is displayed as a square, but the shape does not matter. The sensor 1 displayed on the display unit 45 may be a photograph of the sensor 1. In FIG. 10, as described above, the icon of the sensor 1, that is, the ID number which is the identification information is displayed on the sensor icon. The display unit 45 may change the shape, color, and the like of the sensor icon so that the installation position of the sensor 1 on which the measurement is performed can be easily understood. In the example of FIG. 10, the display unit 45 has a different shape from the sensors 1 of ID1 to ID5 as the sensor 1 whose measurement is performed by the sensor 1 of ID0. Further, the display unit 45 may change the shape, color, etc. of the sensor icon so that the position of the connected sensor 1 can be easily understood. In the example of FIG. 10, the display unit 45 has a different shape from the sensors 1 of ID1 to ID4 as the sensor 1 to which the sensor 1 of ID5 is connected.

Regarding the communication path, the display unit 45 may represent a line connecting the sensor icons with an arrow or an animation so that the transmission direction of the wireless packet can be easily understood. Further, as shown in FIG. 10, the display unit 45 can also display the frequency of use of the communication path, that is, the frequency of relaying, depending on the thickness of the line of the arrow, the difference in color, and the like. The display unit 45 may display the relay frequency of the wireless packet by changing the color, size, or the like of the sensor icon.

Here, it is assumed that a communication failure occurs between the sensor 1 of ID3 and the sensor 1 of ID5. When a communication failure occurs between the sensor 1 of ID3 and the sensor 1 of ID5, for example, when the transmission function of the communication unit 14 of the sensor 1 of ID3 fails, the sensor 1 of ID3 and the sensor 1 of ID5 For example, when there is an obstacle between and the communication path is interrupted. In this case, the display unit 45 does not display the arrow from the sensor 1 of ID3 to the sensor 1 of ID5 in the display shown in FIG. As a result, when the arrow from the sensor 1 of ID4 to the sensor 1 of ID5 is displayed on the display unit 45, the user has failed the transmission function of the communication unit 14 of the sensor 1 of ID3, and the sensor 1 and ID5 of ID3 have failed. It can be estimated that there is an obstacle between the sensor 1 and the sensor 1. In this case, the user identifies the cause of the communication failure by moving the position of the terminal device 4 toward the sensor 1 of the ID 3 and confirming whether the terminal device 4 and the sensor 1 of the ID 3 can be connected. be able to.

Further, by confirming the display content shown in FIG. 10, the user confirms that the relay frequency from the sensor 1 of ID1 to the sensor 1 of ID2 is lower than the relay frequency from the sensor 1 of ID1 to the sensor 1 of ID3. I understand. Therefore, when the user wants the relay frequency from the sensor 1 of ID1 to the sensor 1 of ID3 and the relay frequency from the sensor 1 of ID1 to the sensor 1 of ID2 to be the same, the installation position of the sensor 1 of ID2 is set. , Can be changed to be closer to the sensor 1 of ID1.

In the terminal device 4, the calculation unit 43 may calculate the communication path and the relay frequency for the wireless packet under the conditions specified by the user in the operation unit 42. That is, the calculation unit 43 may filter the received wireless packets. In this case, the display unit 45 displays only the communication path calculated by the calculation unit 43 and the relay frequency. The condition specified by the user in the operation unit 42 is, for example, a case where only the wireless packet transmitted from the sensor 1 of the ID 0 and the wireless packet first received by the sensor 1 of the ID 5 is to be displayed. Further, a specific sensor 1 may be specified for the conditions specified by the user in the operation unit 42. In this case, the terminal device 4 displays only the wireless packet transmitted from the designated sensor 1.

Further, when the state of the terminal device 4 is the wireless packet reception state, the display unit 45 may perform an animation display in which circles concentrically spread from the center of the scan state switching button of the operation unit 42. FIG. 11 is a diagram showing a display example of a scan state switching button of the operation unit 42 of the terminal device 4 according to the first embodiment. Here, it is assumed that the operation unit 42 and the display unit 45 are composed of a touch panel. The scan state switching button is a button for the operation unit 42 to receive an operation of starting or stopping reception of wireless packets from the user. The display unit 45 does not perform an animation display on the scan state switching button of the operation unit 42 when the wireless packet is not received and is not in communication, and displays an animation when the wireless packet is being received and is being communicated. FIG. 11 shows a case where the operation unit 42 for switching the wireless packet reception state has one button, but there are two buttons for the operation unit 42 for switching the wireless packet reception state, for example, two buttons for starting and stopping reception. It is also applicable when there is. That is, the display unit 45 performs an animation display on at least one of the operation parts for starting or stopping the reception of the wireless packet received from the user by the operation unit 42.

Further, in the terminal device 4, when the wireless packet is received by the communication unit 44, the arithmetic unit 43 notifies the user that the wireless packet has been received by sounding a sound, lighting an LED (Light Emitting Diode), or the like. You may.
