(Embodiment)
Hereinafter, an air conditioning system 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

空 気 The air conditioning system 1 shown in FIG. 1 is installed in, for example, an office building, and conditioned the air in an air conditioning space S such as an office space, a corridor, and a toilet.

The air conditioning system 1 uses a first measuring device 110 and a second measuring device 120 that measure the temperature and humidity of the air-conditioned space S, an outdoor unit 200 that heats or cools a refrigerant used for adjusting the temperature and humidity, and a refrigerant. The air conditioner includes a first air conditioner (hereinafter, referred to as a first air conditioner) 210 and a second air conditioner (hereinafter, referred to as a second air conditioner) 220 that are indoor units that adjust the temperature and humidity of the air-conditioned space S. In addition, the air-conditioning system 1 includes the temperature and the humidity measured by the first measuring device 110, the temperature and the humidity measured by the second measuring device 120, the positions of the first measuring device 110 and the second measuring device 120, And a control device 900 for controlling the first air conditioner 210 and the second air conditioner 220 based on

The first measuring device 110 is installed on, for example, a wall surface of an office space or a desk, and notifies the control device 900 of the installed position by emitting far-infrared rays due to heat generation. For this reason, the first measuring device 110 executes various programs including a program for controlling heat generation, a CPU (Central Processing Unit) 111 of FIG. 2, a ROM (Read Only Memory) 112 for storing various programs, and A flash memory 113 and a RAM (Random Access Memory) 114 used as a work area when executing various programs are provided.

{Circle around (1)} The first measuring device 110 includes the heat generating unit 115 shown in FIG. 3 that generates heat in accordance with a signal input from the CPU 111. The heating unit 115 is an example of a heating unit according to the present invention.

The signals of the CPU 111 input to the heat generating unit 115 include a signal SH for instructing heat generation at the temperature TH, a signal SM for instructing heat generation at a temperature TM lower than the temperature TH, and heat generation at a temperature TL lower than the temperature TM. And a signal SS for instructing to stop heat generation. Suitable temperature TH, temperature TM, and temperature TL can be experimentally determined by those skilled in the art.

The heating unit 115 includes a switch SW having a terminal P0 connected to the power supply PW, a terminal PH connected to the thermostat BH, a terminal PM connected to the thermostat BM, and a terminal PL connected to the thermostat BL. Prepare. The switch SW is connected to the CPU 111, and when a signal SH instructing heat generation at the temperature TH is input, connects the terminal P0 connected to the power supply PW to the terminal PH connected to the thermostat BH. The switch SW connects the terminal P0 to the terminal PM when the signal SM is input, and connects the terminal P0 to the terminal PL when the signal SL is input. Further, when the signal SS instructing the stop of the heat generation is input, the switch SW opens the circuit without connecting the terminal P0 to any of the terminals PH, PM, and PL.

(4) The heating unit 115 includes bimetal thermostats BH, BM, and BL each having one end connected to the switch SW and the other end connected to the heating wire R. When the temperature inside the heating section 115 is lower than the temperature TL, all of the thermostats BH, BM, and BL close the circuit. When the temperature inside the heat generating portion 115 is equal to or higher than the temperature TL and lower than the temperature TM, the thermostats BH and BM close the circuit, and the thermostat BL opens the circuit. Furthermore, when the temperature inside the heat generating portion 115 is equal to or higher than the temperature TM and lower than the temperature TH, the thermostat BH closes the circuit, and the thermostats BM and BL open the circuit. Further, when the temperature inside the heat generating section 115 is equal to or higher than the temperature TH, all of the thermostats BH, BM, and BL open the circuit.

(4) The heating unit 115 includes a heating wire R having one end connected to the thermostats BH, BM, and BL, and the other end connected to the power supply PW. The heating wire R generates heat and generates far-infrared rays when the circuit is closed by the switch SW and at least one of the thermostats BH, BM, and BL. On the other hand, the heating wire R stops generating heat when the switch SW opens the circuit or when all of the thermostats BH, BM, and BL open the circuit.

That is, when the signal SH instructing the heat generation at the temperature TH is input, the heat generating section 115 generates heat when the temperature of the heat generating section 115 becomes lower than the temperature TH, and when the temperature of the heat generating section 115 becomes higher than the temperature TH. Stop fever. For this reason, the heat generation state of the heat generation section 115 becomes a steady state in which the heat generation at the temperature TH continues after a sufficient time has elapsed from the input of the signal SH. The waiting time required from the input of the signal SH until the heat generation state becomes the steady state can be determined by an experiment by a person skilled in the art, and the standby time determined by the experiment is stored in advance in the flash memory 113 shown in FIG. ing.

Similarly, the heat generating section 115 generates heat at the temperature TM when the signal SM is input, and generates heat at the temperature TL when the signal SL is input. In addition, since the heat generation unit 115 stops generating heat when the signal SS for instructing the stop of heat generation is input, the temperature of the heat generation unit 115 becomes equal to room temperature after the elapse of the standby time.

第 The first measuring device 110 of FIG. 2 includes the measuring unit 116 having the temperature sensor 116a for measuring the temperature of the air-conditioned space S and the humidity sensor 116b for measuring the humidity of the air-conditioned space S shown in FIG. The measuring unit 116 is separated from the heat generating unit 115 by a thermal insulator in order to accurately measure the temperature and humidity of the air-conditioned space S. In the present embodiment, the heat insulator is described as a fibrous substance such as glass wool, calcium silicate, and ceramic fiber, but is not limited thereto. And the like. The measuring unit 116 is an example of a measuring unit according to the present invention.

Further, the first measuring device 110 transmits the measured temperature information indicating the temperature measured by the measuring unit 116 and the measured humidity information indicating the humidity in accordance with the short-range wireless communication standard BLE (Bluetooth Low Energy) to the control device. And a wireless communication circuit 117 for transmitting data to the wireless communication circuit 900.

In addition, the first measuring device 110 includes a button 118 for inputting a signal according to a user operation to the CPU 111, a video card 119a for drawing an image based on a digital signal output from the CPU 111 and outputting an image signal, An LCD (Liquid Crystal Display) 119b for displaying an image in accordance with the image signal output from the video card 119a.

(4) The CPU 111 of the first measuring device 110 executes the heat generation control process of FIG. 4 for causing the heat generating portion 115 to generate heat according to a pattern representing identification information for identifying the first measuring device 110. The heat generating unit 115 generates heat in accordance with the pattern representing the identification information. The heat generating pattern by the first measuring device 110 (hereinafter, referred to as a first pattern) and the heat generating pattern by the second measuring device 120 (hereinafter, referred to as a second pattern). ) Are different from each other.

(5) The flash memory 113 of the first measuring device 110 previously stores the pattern table of FIG. 5 in which information indicating a heat generation pattern is stored in advance. In the pattern table, identification information represented by a heat generation pattern is associated with information indicating the first to N-th heat generation states (hereinafter, referred to as heat generation states) performed according to the heat generation pattern. Has been saved.

In the pattern table, the heat generation state includes a symbol “strong” indicating a state of generating heat at the temperature TH, a symbol “medium” indicating a state of generating heat at the temperature TM, a symbol “weak” indicating a state of generating heat at the temperature TL, and It is represented by four types of symbols, "null", which represent a state in which no operation is performed. For this reason, 4 ^N −1 kinds of identification information are represented by a pattern that generates heat N times.

The CPU 111 of the first measuring device 110 executes the heat generation control process at the timing when the power is turned on or when the wireless communication circuit 117 receives a command for executing the heat generation control process in FIG. To start.

When the CPU 111 starts the heat generation control process, the CPU 111 acquires the communication address assigned to the wireless communication circuit 117, and uses the acquired communication address as the identification information of the first measuring device 110. This is because the communication address of the first measuring device 110 is usually different from the communication address of the second measuring device 120.

Next, the CPU 111 acquires the first to N-th heat generation states associated with the identification information of the first measurement device 110 from the pattern table of FIG. 5, and generates heat in the obtained heat state. The pattern is set as a first pattern (step S01).

Next, the CPU 111 initializes a variable n representing the number of heat generation with a value “1” (step S02), and then determines whether the number of heat generation represented by the variable n is equal to or less than the number N of heat generation performed in the first pattern. It is determined whether or not it is (step S03).

At this time, when the CPU 111 determines that the variable n is equal to or less than N (step S03; Yes), the CPU 111 controls the heat generation unit 115 of FIG. 2 to generate heat in the n-th heat generation state acquired in step S01 (step S03). S04). For example, if the n-th heat generation state is a state in which heat is generated at a temperature TH represented by a symbol “strong”, the CPU 111 inputs a signal SH instructing heat generation at the temperature TH to the heat generation unit 115.

Next, the CPU 111 starts measuring the elapsed time from when the heat generation is controlled in step S04 using, for example, a software timer. Thereafter, the CPU 111 reads the standby time stored in the flash memory 113, and determines whether the heating state of the heating unit 115 is in a steady state based on whether the elapsed time measured by the software timer has exceeded the standby time. Is determined (step S05). At this time, if the elapsed time does not exceed the standby time, the CPU 111 determines that it is not in the steady state (step S05; No), sleeps for a certain time, and then executes the process of step S05 again.

On the other hand, when determining that the CPU 111 is in the steady state because the elapsed time has exceeded the standby time (step S05; Yes), the CPU 111 generates heat generation number information indicating the number of heat generations and heat generation state information indicating the changed heat generation state. Are output to the wireless communication circuit 117 of FIG. 2 with the control device 900 as a destination (step S06). Next, the wireless communication circuit 117 transmits the heat generation frequency information and the heat generation state information to the control device 900.

(4) Thereafter, the CPU 111 starts measuring the time during which the instructed heat generation state continues, for example, using a software timer. Next, the CPU 111 reads, for example, from the flash memory 113 a preset time set by the maintenance manager of the air-conditioning system 1 as the time for continuing the heat generation, and determines whether the measured heat generation duration exceeds the set time. It is determined whether or not it is (step S07). At this time, if the CPU 111 determines that the duration of the heat generation does not exceed the set time (step S07; No), the CPU 111 sleeps for a certain time and then executes the processing of step S07 again.

On the other hand, if the CPU 111 determines that the duration of heat generation has exceeded the set time (step S07; Yes), the CPU 111 increases the variable n representing the number of heat generation by “1” (step S08), and then proceeds to step S03. Return and repeat the above process.

In step S03, when the CPU 111 determines that all of the series of heat generation according to the first pattern has been performed because the variable n is larger than N (step S03; No), the CPU 111 ends the execution of the heat generation control process.

The CPU 111 of the first measuring device 110 measures the temperature and humidity of the air-conditioned space S after a lapse of the same length of time as the standby time stored in the flash memory 113 after the execution of the heat generation control process ends. The execution of the temperature / humidity measurement process (not shown) is repeated at regular intervals. This is because the temperature of the first measuring device 110 is considered to be the same as the temperature of the air-conditioned space S if the time equal to or longer than the standby time has elapsed since the heat generation unit 115 finished generating heat.

(4) When the execution of the heat generation control process is resumed, the CPU 111 suspends the execution of the temperature and humidity measurement process that is repeated at a constant cycle. If the heat generating unit 115 starts generating heat, the temperature measured by the first measuring device 110 may be higher than the temperature of the air-conditioned space S, and the humidity measured by the first measuring device 110 is This is because the humidity may be lower than the humidity. After that, the CPU 111 restarts the execution of the temperature / humidity measurement process that is repeated at a constant cycle after a lapse of the standby time from the end of the execution of the heat generation control process.

When the execution of the temperature / humidity measurement process is started, the CPU 111 of the first measuring device 110 generates measured temperature information based on the signal output from the temperature sensor 116a in FIG. 2, and performs measurement based on the signal output from the humidity sensor 116b. Generate humidity information. After that, the CPU 111 outputs the measured temperature information and the measured humidity information to the control device 900 as a destination and transmits the measured temperature information and the measured humidity information to the control device 900 after the wireless communication circuit 117 transmits the measured temperature information and the measured humidity information to the control device 900. The execution of the temperature and humidity measurement processing ends.

The second measuring device 120 has the same hardware as the first measuring device 110 and performs the same function as the first measuring device 110. That is, the second measuring device 120 includes a heating unit and a measuring unit (not shown) having the same configuration and functions as the heating unit 115 and the measuring unit 116 of the first measuring device 110. Similarly to the first measuring device 110, the second measuring device 120 executes the heat generation control process of FIG. 4 to cause the heat generating portion (not shown) to generate heat according to the second pattern representing the communication address of the second measuring device 120. .

The first air conditioner 210 of FIG. 1 generates a first thermal image that is a thermal image of the air-conditioned space S in which the first measuring device 110 and the second measuring device 120 are installed, and generates the generated first thermal image. The information is transmitted to the control device 900 that specifies the positions of the first measuring device 110 and the second measuring device 120.

For this reason, the first air conditioner 210 executes various programs including a program for controlling generation and transmission of the first thermal image, the CPU 211 in FIG. 6, a ROM 212 and a flash memory 213 storing various programs, and And a RAM 214 used as a work area when executing various programs.

{Circle around (1)} The first air conditioner 210 includes a first radiation sensor 215 that generates a first thermal image representing the heat distribution of the air-conditioned space S based on the measurement result of the radiation heat. Since the first radiation sensor 215 measures radiant heat, for example, it is difficult or difficult to detect near-infrared rays emitted from an infrared LED (Light Emitting Diode) of a remote controller, but detects far-infrared rays emitted from a heat body. it can.

The first radiation sensor 215 includes a radiation heat measuring unit 251 having a lens 251a that transmits far infrared rays, and a thermopile array 251b that converts radiant heat generated by the far infrared rays transmitted through the lens 251a into an electric signal.

The radiation heat measuring unit 251 sets the optical axis of the lens 251a in the horizontal direction LA1 in which the angle formed with the positive direction of the Xw axis is θ1 in the world coordinate system XwYwZw in which the vertical direction shown in FIG. 7 is the positive direction of the Zw axis. It is installed for. That is, the installation direction of the optical axis of the lens 251a is the horizontal direction LA1.

The thermopile array 251b is composed of Ny thermopile elements arranged in one column in the vertical direction corresponding to Ny pixels arranged in one column in the sub-scanning direction of the first thermal image shown in FIG.

た め For the sake of simplicity, the following description is based on the assumption that Ny is an odd number. A thermopile element (hereinafter, referred to as a center element) located at the center of the thermopile array 251b is arranged at a position overlapping the optical axis of the lens 251a. When the optical axis is directed in the horizontal direction LA1, the central element outputs an electric signal corresponding to radiant heat generated by far infrared rays coming from the horizontal direction LA1.

When the optical axis is oriented in the horizontal direction LA1, the thermopile element disposed one position higher than the center element has a position where the center of the lens 251a shown in FIG. 9 is installed (hereinafter, the installation position of the lens 251a). An electric signal corresponding to radiant heat generated by far-infrared rays arriving from a direction lower than the horizontal direction LA1 by a step angle φ from the horizontal direction LA1 is output. However, the notch angle φ is an angle determined by the focal length of the lens 251a and the size of the thermopile element in the vertical direction. That is, the notch angle φ can be specified by a conventional calculation method using a right-angled triangle having an adjacent side having a length equal to the focal length and a paired side having a length equal to the size of the thermopile element.

Similarly, the thermopile elements arranged at positions i above the center element output an electric signal corresponding to radiant heat generated by far infrared rays arriving from a direction below the horizontal direction LA1 by a step angle φ × i. Here, i is a natural number of 2 or more and (Ny-1) / 2 or less.

Similarly, the thermopile element disposed i positions below the central element outputs an electric signal corresponding to radiant heat generated by far infrared rays arriving from a direction above the horizontal direction LA1 by a step angle φ × i. .

The first radiation sensor 215 in FIG. 6 includes a scanning unit 252 including a stepping motor (not shown) that scans the radiation heat measuring unit 215. The scanning unit 252 adjusts the direction of the optical axis of the lens 251a without changing the installation position PA1 of the lens 251a while maintaining the light receiving surface of the thermopile array 251b perpendicular to the optical axis of the lens 251a in the scanning of the radiant heat measuring unit 215. Change to a different direction from before the change, while keeping it horizontal.

Before the scanning unit 252 changes the direction of the optical axis of the lens 251a from the horizontal direction LA1 in FIG. 7, the thermopile array 251b outputs an electric signal representing the first pixel column of the first thermal image. Next, when the scanning unit 252 changes the direction of the optical axis of the lens 251a from the horizontal direction LA1 to the positive direction of the Yw axis by the step angle φ, the thermopile array 251b outputs an electric signal representing the second pixel column. Is output. Similarly, when the scanning unit 252 further changes the direction of the optical axis by the step angle φ, the thermopile array 251b outputs an electric signal representing the third pixel column. By repeating the same processing, the thermopile array 251b outputs an electric signal representing the fourth to Nxth pixel columns. Thereafter, the scanning unit 252 returns the direction of the optical axis of the lens 251a to the horizontal direction LA1 before scanning.

The first air conditioner 210 in FIG. 6 includes a first thermal image generation circuit 216 that generates a first thermal image based on electric signals representing the first to Nxth pixel columns output from the thermopile array 251b. . The first thermal image generation circuit 216 is an example of a first thermal image generation unit according to the present invention.

The first air conditioner 210 is connected to the communication cable C of FIG. 1, and transmits the first thermal image generated by the first radiation sensor 215 to the control device 900 and receives a command from the control device 900 by wire communication. The circuit 217 is provided.

The first air conditioner 210 includes a fan 218 for circulating the air in the air-conditioned space S based on a command received from the control device 900, and a motor 219 for rotating the fan 218.

ＣＰＵ The CPU 211 of the first air conditioner 210 starts execution of an image generation process (not shown) for generating a first thermal image at a timing when the power is turned on. When the CPU 211 starts the image generation processing, the CPU 211 controls the first radiation sensor 215 to generate a first thermal image, and performs control to transmit the first thermal image generated by the first radiation sensor 215 to the control device 900. This is performed by the wired communication circuit 217.

After that, the CPU 211 reads out from the flash memory 213 a preset interval set as a time interval for generating the first thermal image, for example, by the maintenance manager of the air conditioning system 1 of FIG. The set interval is set to an interval shorter than the set time set for the first measuring device 110 and the second measuring device 120, as the time during which the first measuring device 110 and the second measuring device 120 continue to generate heat. This is because at least one first thermal image is generated after the first measuring device 110 and the second measuring device 120 change the state of heat generation and before changing the state of heat generation next time.

When reading the set interval, the CPU 211 starts the timing using the software timer, then sleeps until the measured elapsed time becomes longer than the set interval, and then performs a process of performing control to generate the first thermal image. The above process is repeated.

２The second air conditioner 220 of FIG. 1 includes the same hardware as the first air conditioner 210 and performs the same function as the first air conditioner 210. That is, the second air conditioner 220 includes a second radiation sensor (not shown) and a second thermal image generation circuit. The second thermal image generation circuit is an example of a second thermal image generation unit according to the present invention.

The second radiation sensor included in the second air conditioner 220 is installed with its optical axis directed in the horizontal direction LA2 where the angle formed with the positive direction of the Xw axis shown in FIG. 7 is θ2. That is, the installation direction of the optical axis of the second radiation sensor is the horizontal direction LA2. Further, the direction of the optical axis of the second radiation sensor can be changed without changing the installation position PA2 of the lens provided in the second radiation sensor, while maintaining the horizontal position.

1 is, for example, a centralized remote controller installed on the wall of the air-conditioned space S, and controls the first air conditioner 210 and the second air conditioner 220 according to a user operation.

Therefore, the control device 900 executes various programs including the air-conditioning control program, the CPU 901 in FIG. 10, the ROM 902 and the flash memory 903 for storing various programs, and the work area when executing the various programs. RAM 904 to be used.

The control device 900 is connected to the wireless communication circuit 907a that wirelessly communicates with the first measuring device 110 and the second measuring device 120, and the communication cable C in FIG. 1, and communicates with the first air conditioner 210 and the second air conditioner 220. A wired communication circuit 907b. The wireless communication circuit 907a is an example of a first communication unit according to the present invention, and the wired communication circuit 907b is an example of a second communication unit according to the present invention.

The control device 900 includes a button 908 for inputting a signal according to a user operation, and a video card 909a and an LCD 909b having the same configuration and functions as the video card 119a and the LCD 119b shown in FIG. Control device 900 may include a touch panel instead of button 908.

The CPU 901 of the control device 900 specifies the installation position of the first measurement device 110 or the second measurement device 120 that notifies the position by heat generation based on the first thermal image and the second thermal image. Execute the process.

Accordingly, the CPU 901 acquires the first thermal image and the second thermal image from the wired communication circuit 907b, and acquires the first thermal image and the second thermal image acquired by the acquiring unit 910 in FIG. 12 and the acquiring unit 910.

Further, the CPU 901 determines the installation positions of the first measuring device 110 and the second measuring device 120 specified by the specifying unit 920, and the temperature and the humidity measured by the first measuring device 110 and the second measuring device 120. Thus, it functions as the control unit 930 that controls the first air conditioner 210 and the second air conditioner 220. The control unit 930 is an example of a control unit according to the present invention.

The flash memory 903 in FIG. 10 functions as an information storage unit 990 that stores information used in the position specifying process.

The information storage unit 990 stores the pixel value table of FIG. 13 in which information indicating a range of pixel values observed by an experiment that causes the first measuring device 110 and the second measuring device 120 to generate heat is stored in advance. .

In the pixel value table, the state of heat generation and the pixels of the pixels representing the first measurement device 110 and the second measurement device 120, which were observed in an experiment in which the first measurement device 110 and the second measurement device 120 generate heat in the state, are shown.

Will be saved.

When the wireless communication circuit 907a in FIG. 10 receives the heat generation state information indicating the heat generation state of the “first measurement device 110”, the CPU 901 of the control device 900 specifies the installation position of the “first measurement device 110”. Then, the execution of the position specifying process of FIG. 11 is started.

On the other hand, when the CPU 901 of the control device 900 receives the heat generation state information indicating the heat generation state by the “second measurement device 120”, the CPU 901 determines the position of the “second measurement device 120” by specifying the installation position. Start execution of specific processing.

(4) The timing at which the first measuring device 110 transmits the heat generation state information and the timing at which the second measurement device 120 transmits the heat generation state information are not time-divided. Therefore, the CPU 901 of the control device 900 executes the position specifying process for specifying the position of the “first measuring device 110” and the position specifying process for specifying the position of the “second measuring device 120” in parallel. May be executed in some cases. However, in order to simplify the description, first, a position specifying process for specifying the installation position of the “first measuring device 110” will be described, and then a process for specifying the installation position of the “second measuring device 120” will be described. The position specifying process will be described.

When the position specifying process of FIG. 11 for specifying the installation position of the first measuring device 110 is started, the acquisition unit 910 sets the first pixel and the second pixel corresponding to the state of heat generation by the first measuring device 110. The detection processing of FIG. 17 is performed (step S11).

When the execution of the detection process is started, the acquisition unit 910 acquires a communication address used by the wireless communication circuit 907a for communication with the first measurement device 110 as identification information of the first measurement device 110. Next, the acquisition unit 910 acquires the heat generation state information and the heat generation frequency information received by the wireless communication circuit 907a from the first measuring device 110 from the wireless communication circuit 907a (Step S21).

Thereafter, the acquiring unit 910 sleeps until the wired communication circuit 907b in FIG. 10 receives the first thermal image from the first air conditioner 210. Thereafter, when the wired communication circuit 907b receives the first thermal image, the acquiring unit 910 acquires the first thermal image from the wired communication circuit 907b (Step S22).

After that, the specifying unit 920, based on the pixel value table in FIG. 13, stores information indicating the minimum value of the pixel value associated with the heat generation state information acquired in step S21 and information indicating the maximum value of the pixel value. get. Next, the identification unit 920 detects one or more pixels having a pixel value equal to or greater than the minimum value and equal to or less than the maximum value represented by the acquired information from the first thermal image acquired in step S22. Then, one or a plurality of detected pixels are specified as the first pixels (step S23).

Thereafter, by performing the same processing as in steps S22 and S23, a second thermal image is obtained (step S24), and one or a plurality of second pixels corresponding to the state of heat generation are specified from the second thermal image. (Step S25).

After that, the specifying unit 920 sets the Xc axis in which the main scanning direction of the first thermal image shown in FIG. 8 is the positive direction, the Yc axis in which the sub scanning direction is the positive direction, and The coordinate value of the camera coordinate system XcYc having the position of the origin Oc is specified for one or a plurality of first pixels and one or a plurality of second pixels.

Next, the specifying unit 920 determines the identification information, the heat generation frequency information, and the heat generation state information of the first measuring device 110 acquired in step S21 of FIG. 17 and the one or more first heat measurement information specified in steps S23 and S25. A record in which the coordinate value of one pixel and the coordinate values of one or more second pixels are associated with each other. After that, the specifying unit 920 stores the generated record in the detection result table of FIG. 14 (Step S26).

Next, the specifying unit 920 determines whether or not the number of times of heat represented by the information on the number of times of heat acquired in step S21 is the last number of times of heat generation N according to the pattern of heat generation (step S27). At this time, when the specifying unit 920 determines that the number of heat generations is not the last number of heat generations N and is in the middle of a series of heat generations according to the first pattern (Step S27; No), the above-described processing is repeated from Step S21.

On the other hand, when the specifying unit 920 determines that a series of heat generations according to the first pattern is completed because the heat generation number is the last heat generation number N (step S27; Yes), the detection unit 920 of FIG. , A plurality of records in which the identification information obtained in step S21 is stored. Next, the specifying unit 920 calculates the coordinate values of one or more first pixels stored in common with the acquired records and the one or more second pixels stored in common with the records. And the coordinate value of. This is for specifying one or a plurality of first pixels and one or a plurality of second pixels that are commonly detected in the state of heat generation N times according to the first pattern (step S28 in FIG. 17). That is, when the first measuring device 110 is generating heat according to the first pattern, the second measuring device 120 generates heat according to the second pattern, and the heat generation state of the first measuring device 110 is accidentally changed to the second measuring device. This is because, when the heat generation state is the same as the heat generation state of 120, pixels representing the radiant heat due to the far infrared rays coming from the second measurement device 120 are excluded.

In step S28, when the specifying unit 920 specifies the coordinate values of the plurality of first pixels stored in common in the plurality of records, the specifying unit 920 specifies the smallest circle including all of the specified plurality of first pixels. The pixel located at the center of the specified circle is specified as a first pixel representing the plurality of first pixels. However, the present invention is not limited to this. For example, a pixel having a coordinate value closest to the average value of the coordinate values of the plurality of first pixels is specified as a first pixel representing the plurality of first pixels. Is also good.

Similarly, in step S28, the specifying unit 920 specifies a second pixel representing one or a plurality of second pixels commonly stored in a plurality of records. After that, the specifying unit 920 ends the execution of the detection processing.

After executing the detection processing in step S11 in FIG. 11, the specifying unit 920 travels from the first air conditioner 210 to the first measuring device 110 based on the coordinate value of the first pixel specified in step S28 in FIG. Then, the straight line specifying process of FIG. 18 for specifying the first straight line L11 shown in FIG. 7 is executed (step S12).

Here, in order to facilitate the description, the following description will be given by taking as an example a case where the pixel IE11 shown in FIG. 8 is specified as the first pixel in step S28 in FIG.

When the execution of the straight line specifying process is started, the specifying unit 920 acquires the step angle φ of the optical axis of the first radiation sensor 215 associated with the communication address of the first air conditioner 210 from the installation status table of FIG. . Next, the specifying unit 920 multiplies the Xc coordinate value of the first pixel IE11 by the step angle φ. Thereby, the specifying unit 920 is the installation direction LA1 of the optical axis of the first air conditioner 210 before scanning illustrated in FIG. 7 and the far infrared rays from the first measurement device 110, and is represented by the first pixel IE11. An arrival angle φxy11 formed between the arrival direction (hereinafter, referred to as a first direction) D11 of the far-infrared ray that has generated the radiant heat and the projection onto the XwYw plane is specified.

Similarly, the specifying unit 920 multiplies the Yc coordinate value of the first pixel IE11 by the notch angle φ to project the optical axis installation direction LA1 shown in FIG. 9 onto the YwZw plane and the first direction D11. The arrival angle φxz11 formed by the projection onto the YwZw plane is specified.

After that, the specifying unit 920 acquires the installation angle θ1 representing the installation direction LA1 of the optical axis associated with the communication address of the first air conditioner 210 from the installation status table of FIG. After that, the specifying unit 920 specifies the vector of the world coordinate system XwYwZw representing the first direction D11 using the arrival angle φxy11 and the arrival angle φxz11 and the installation angle θ1 (step S31).

Next, the specifying unit 920 acquires the coordinate value of the installation position PA1 of the first air conditioner 210 in the world coordinate system XwYwZw from the installation status table of FIG. 15 based on the communication address of the first air conditioner 210 (step S32). ).

After that, the specifying unit 920 determines the first air conditioner based on the coordinate value indicating the installation position PA1 of the first air conditioner 210 acquired in step S32 and the vector indicating the first direction D11 specified in step S31. An equation representing a first straight line L11 directed from the installation position PA1 in the first direction D11 which is a direction of arrival of far infrared rays is specified (step S33).

After that, the specifying unit 920 specifies the equation representing the second straight line L21 that goes from the installation position PA2 of the second air conditioner 220 in the second direction D21 by executing the same processing as in steps S31 to S33. However, the second direction D21 is the direction of arrival of the far infrared rays arriving from the first measuring device 110 to the second air conditioner 220 (steps S34 to S36). After that, the specifying unit 920 ends the execution of the straight line specifying process.

After executing the straight line specifying process in step S12 of FIG. 11, the specifying unit 920 calculates the coordinate value of the intersection PM1 of the first straight line L11 and the second straight line L21 shown in FIG. It is specified using an equation representing the two straight lines L21. Next, the specifying unit 920 specifies the coordinate value of the specified intersection PM1 as the installation position of the first measuring device 110 (Step S13).

After that, the specifying unit 920 stores the identification information of the first measuring device 110 acquired in step S11 and the information indicating the specific position of the first measuring device 110 in the specific position table of FIG. Later (step S14), the execution of the position identification processing ends.

Next, a position specifying process for specifying the position of the “second measuring device 120” will be described. When the wireless communication circuit 907a of the control device 900 receives the heat generation state information from the second measuring device 120, the CPU 901 of the control device 900 starts executing the position specifying process for specifying the position of the second measuring device 120.

First, the CPU 901 detects the first pixel corresponding to the state of heat generation by the second measuring device 120 from the first thermal image by executing the detection processing of FIG. 17, and removes the second pixel from the second thermal image. It is detected (step S11).

Next, the specifying unit 920 specifies the equation representing the first straight line L12 from the installation position PA1 of the first air conditioner 210 in the first direction D12 by executing the straight line specifying process of FIG. 18 (Step S12). . However, the first direction D12 is the arrival direction of far-infrared rays arriving at the first air conditioner 210 from the second measuring device 120. Similarly, the specifying unit 920 specifies an equation representing a second straight line L22 that extends from the installation position PA2 of the second air conditioner 220 in the second direction D22. However, the second direction D22 is an arrival direction of far-infrared rays arriving at the second air conditioner 220 from the second measuring device 120.

After that, the specifying unit 920 specifies the coordinate value of the intersection PM2 between the first straight line L12 and the second straight line L22 illustrated in FIG. 7 and specifies the coordinate value of the specified intersection PM2 as the installation position of the second measuring device 120. (Step S13).

After that, the specifying unit 920 stores the identification information of the second measuring device 120 acquired in step S11 and the information indicating the specific position of the second measuring device 120 in association with each other in the specific position table of FIG. Later (step S14), the execution of the position identification processing ends.

When a button 908 of the control device 900 illustrated in FIG. 10 inputs a signal corresponding to a user operation, the CPU 901 determines a temperature set by the user (hereinafter, referred to as a set temperature) and a set humidity (hereinafter, set humidity). Is specified based on the input signal. After that, the CPU 901 stores the set temperature information indicating the set temperature and the set humidity information indicating the set humidity in the flash memory 903.

When the wireless communication circuit 907a of the control device 900 shown in FIG. 10 receives the measured temperature information and the measured humidity information from the first measuring device 110 or the second measuring device 120, the CPU 901 sets the first air conditioner 210 and the second air conditioner The air conditioning control process of FIG.

When the execution of the air conditioning control process is started, the acquisition unit 910 in FIG. 12 acquires the measured temperature information and the measured humidity information from the wireless communication circuit 907a. The acquiring unit 910 acquires a communication address used by the wireless communication circuit 907a to receive the measured temperature information and the measured humidity information as identification information of the first measuring device 110 or the second measuring device 120 (Step S41).

Next, the control unit 930 obtains information indicating the specific position associated with the identification information obtained in step S41 from the specific position table in FIG. 16 (step S42).

The control unit 930 also acquires the set temperature information and the set humidity information from the flash memory 903 shown in FIG. 10 (Step S43).

Thereafter, the control unit 930 performs control to set the temperature and humidity at the specific position of the first measuring device 110 or the second measuring device 120 acquired in step S42 to the set temperature and the set humidity. , Based on the information indicating the specific position, and the set temperature information and the set humidity information. Next, the control unit 930 sends a command to the wired communication circuit 907b with the first air conditioner 210 and the second air conditioner 220 as destinations in order to perform the determined control on the first air conditioner 210 and the second air conditioner 220. Output (Step S44). After that, after the wired communication circuit 907b transmits the command, the control unit 930 ends the execution of the air conditioning control process.

According to these configurations, the heat generated by the first measuring device 110 is generated by the first measuring device 110, the first air conditioner 210 that generates the first thermal image, and the second air conditioner that generates the second thermal image. As long as no person or object is present between the air conditioner and the air conditioner 220, the air is transmitted by radiation regardless of the number and position of the person and the object staying in the air-conditioned space. The heat generated by the second measuring device 120 is also transmitted by radiation. For this reason, the air-conditioning system 1 is more accurate than the conventional technology in which the positions of the first measuring device 110 and the second measuring device 120 are specified based on the detection intensity of the electromagnetic wave. The position can be specified.

減 衰 Furthermore, the attenuation due to the far-infrared distance is smaller than the attenuation due to the visible and near-infrared distance. For this reason, even if the distance from the first measuring device 110 and the second measuring device 120 to the first air conditioner 210 and the second air conditioner 220 is long, the air conditioning system 1 performs the first measurement by blinking the LED, for example. The positions of the first measuring device 110 and the second measuring device 120 can be specified with higher accuracy than the conventional technology for detecting the positions of the device 110 and the second measuring device 120.

遠 Far infrared rays are not affected by humidity, or are less affected than visible light and near infrared rays. For this reason, even if the humidity of the air-conditioned space S increases, the air-conditioning system 1 can specify the positions of the first measuring device 110 and the second measuring device 120 with higher accuracy than in the related art.

Furthermore, if the conventional air conditioning system only includes an air conditioner having a radiation sensor and a control device that controls the air conditioner based on a thermal image generated by the radiation sensor, control is performed by the conventional control device. The air conditioning system 1 according to the present embodiment can be improved simply by installing the program of the device 900. For this reason, the conventional air conditioning system can be improved to the air conditioning system 1 according to the present embodiment at low cost.

Further, according to these configurations, control device 900 determines the installation position of first measurement device 110 based on the first thermal image generated by first air conditioner 210 and the second thermal image generated by second air conditioner 220. And the installation position of the second measuring device 120 is specified. Therefore, the maintenance manager of the air conditioning system 1 does not need to operate the control device 900 to input the installation position of the first measurement device 110 and the installation position of the second measurement device 120 to the control device 900.

According to these configurations, first measuring device 110 generates heat according to the first pattern, and control device 900 specifies a pixel having a pixel value corresponding to radiant heat generated according to the first pattern. For this reason, even if an object that generates heat exists in the air-conditioned space S other than the first measuring device 110, the control device 900 more reliably identifies the position of the first measuring device 110 based on the first pattern than before. it can.

According to these configurations, the time interval at which the first air conditioner 210 generates the first thermal image and the time interval at which the second air conditioner 220 generates the second thermal image are determined by the first measuring device 110 The time interval for changing the heat generation state according to the first pattern and the time interval for the second measurement device 120 to change the heat generation state according to the second pattern are shorter. For this reason, the first air conditioner 210 and the second air conditioner 220 reflect all of the multiple heat generations according to the first pattern and all of the multiple heat generations according to the second pattern. The image and the second thermal image can be generated more reliably than before.

Further, according to these configurations, the first measuring device 110 generates heat according to the first pattern for identifying the first measuring device 110, and the second measuring device 120 generates heat according to the second pattern for identifying the second measuring device 120. I do. For this reason, even if the second measuring device 120 generates heat according to the second pattern while the first measuring device 110 generates heat according to the first pattern, the control device 900 generates a second signal based on the first pattern and the second pattern. The position of the first measuring device 110 and the position of the second measuring device 120 can be specified more reliably than before.

Further, according to these configurations, the first measuring device 110 generates heat according to the first pattern representing the communication address of the first measuring device 110, and the second measuring device 120 generates the second pattern representing the communication address of the second measuring device 120. Heat is generated according to two patterns. Therefore, the first measurement device 110 and the second measurement device 120 can generate heat in different patterns without setting a heat generation pattern in the first measurement device 110 and the second measurement device 120.

In the present embodiment, the heating section 115 of the first measuring device 110 has been described as being configured by the switch SW, the thermostats BH, BM, and BL, and the heating wire R in FIG. 3, but is not limited thereto. Not in translation.

The heating unit 115 of the first measuring device 110 has, instead of the configuration shown in FIG. 3, one end connected to the heating wire R connected to the power supply PW, one end connected to the heating wire R, and the other end connected to the power supply PW. And a not-shown MCU (Micro Controller Unit) that controls ON and OFF of the switch. The heating unit 115 further includes a temperature sensor (not shown) installed around the heating wire R. The MCU opens and closes a switch based on a signal output from the temperature sensor and a signal output from the CPU 111. May be controlled.

For example, after a signal SH instructing heat generation at the temperature TH from the CPU 111 is input to the MCU, while a signal corresponding to a measured temperature less than the temperature TH is input from the temperature sensor, a signal for instructing ON (hereinafter, referred to as “signal”). , ON signal) to the switch. On the other hand, after the signal SH is input from the CPU 111, the MCU outputs an OFF signal (hereinafter referred to as an OFF signal) while a signal corresponding to a measured temperature equal to or higher than the temperature TH is input from the temperature sensor. Is output to the switch.

Similarly, after the signal SM is input, the MCU outputs an ON signal while the signal corresponding to the measured temperature lower than the temperature TM is input, and receives the signal corresponding to the measured temperature equal to or higher than the temperature TM. During this time, an OFF signal is output. Similarly, after the signal SL is input, the MCU outputs an ON signal while the signal corresponding to the measured temperature lower than the temperature TL is input, and receives the signal corresponding to the measured temperature equal to or higher than the temperature TL. During this time, an OFF signal is output.

{Circle around (4)} After the signal SS for instructing the stop of heat generation is input, the MCU outputs an OFF signal until one of the signal SH, the signal SM, and the signal SL is input next.

After executing step S23 in FIG. 17, the control device 900 according to the present modification determines whether the first pixel corresponding to the heat generation state of the first measurement device 110 has been identified from the first thermal image. Is also good. If the control device 900 determines that the first pixel could not be specified, the control device 900 may transmit to the first measurement device 110 a command to correct the heat generation temperature and restart the heat generation according to the pattern.

For example, after increasing the heat generation temperature by T degrees Celsius, the control device 900 may transmit to the first measurement device 110 a command to restart the heat generation. According to the received command, the CPU 111 of the first measuring device 110 operates at the temperature TH + T when the signal SH is input, at the temperature TM + T when the signal SM is input, and at the temperature TM + L when the signal SL is input. The MCU is controlled to generate heat from the heating wire R.

Similarly, the control device 900 may transmit to the first measuring device 110 a command to restart the heat generation after reducing the heat generation temperature by T degrees Celsius. According to the received command, the CPU 111 of the first measuring device 110 determines whether the temperature is TH-T when the signal SH is input, the temperature is TM-T when the signal SM is input, and the signal SL is input when the signal SM is input. The MCU is controlled so that the heating wire R generates heat at the temperature TM-L. Thereafter, the CPU 111 of the first measuring device 110 executes the heat generation control process of FIG. 4 again.

Similarly, if the control device 900 determines that the second pixel could not be specified after executing step S25 in FIG. 17, the control device 900 issues a command for correcting the heat generation temperature and re-starting heat generation according to the pattern. It may be transmitted to the measuring device 110.

発 熱 Furthermore, similarly, the heat generating portion of the second measuring device 120 may include the heating wire R, a switch, an MCU, and a temperature sensor (not shown). The control device 900 may transmit, to the second measuring device 120, a command to correct the heat generation temperature and to restart the heat generation according to the pattern.

(Modification 7 of Embodiment)
In the present embodiment, the first measuring device 110 and the second measuring device 120 are described as generating heat in a pattern representing a communication address used for communication with the control device 900, but the present invention is not limited to this.

The control device 900 determines, for example, a heat generation pattern by the first measurement device 110 and a heat generation pattern by the second measurement device 120 at random, and determines the determined pattern by the first measurement device 110 and the second measurement device. It may be transmitted to the device 120.

(Eighth Modification of Embodiment)
In the present embodiment, control unit 930 of control device 900 has been described as controlling first air conditioner 210 and second air conditioner 220 based on the first thermal image and the second thermal image, but the present invention is not limited to this. Not necessarily.

The control unit 930 of the control device 900 generates heat at a temperature higher than the upper limit temperature set by the maintenance manager of the air conditioning system 1 based on the pixel value of the first thermal image and the pixel value of the second thermal image. When it is determined that the object exists in the air-conditioned space S, control for stopping heat generation may be performed on the first measuring device 110 and the second measuring device 120. The upper limit temperature set by the maintenance manager may be any temperature as long as it is set to a temperature higher than the temperature Th which is the maximum value of the heat generation temperature according to the heat generation pattern.

According to this configuration, it is possible to prevent the first measuring device 110 or the second measuring device 120 from continuously generating heat at a temperature higher than the upper limit temperature set by the maintenance manager due to, for example, a failure or an erroneous operation.

The control unit 930 of the control device 900 specifies the position of an object that generates heat at a temperature higher than the upper limit temperature (hereinafter, referred to as a high-temperature object) based on the first thermal image and the second thermal image, and Control for displaying the position of the object and a message indicating the presence of the high-temperature object may be performed on the LCD 909b in FIG.

(Modification 9 of Embodiment)
In the present embodiment, it is described that the first measuring device 110 generates heat according to the first pattern for identifying the first measuring device 110, and the second measuring device 120 generates heat according to the second pattern for identifying the second measuring device 120. However, it is not limited to this.

The first measuring device 110 includes a storage battery (not shown). When the CPU 111 determines that the storage amount of the storage battery is equal to or larger than the amount set by the maintenance manager of the air conditioning system 1, the CPU 111 generates heat according to the first pattern. May be instructed to the heat generating unit 115. On the other hand, when the CPU 111 of the first measuring device 110 determines that the storage amount of the storage battery is less than the set amount, the CPU 111 instructs the heat generation unit 115 to generate heat according to the shortened first pattern. Is also good.

The pattern obtained by shortening the first pattern may be, for example, a pattern that performs the first heat generation to the K-th heat generation according to the first pattern. Here, K is a natural number smaller than N. Further, the pattern obtained by shortening the first pattern may be, for example, a pattern that performs the (N−K + 1) th heat generation to the Nth heat generation according to the first pattern.

The CPU 111 of the first measuring device 110 may transmit, to the control device 900, information reporting the end of the heat generation according to the pattern after the heat generation according to the shortened pattern ends. Further, the CPU 111 of the first measuring device 110 may transmit information indicating the total number of times of heat generation according to the shortened pattern to the control device 900 before starting heat generation according to the shortened pattern.

As in the case of the first measuring device 110, the second measuring device 120 may generate heat in accordance with a shortened first pattern when the storage amount of the storage battery is less than a set amount.

Further, the control unit 930 of the control device 900 determines the position of the first measuring device 110 or the second measuring device 120 that generates heat in the shortened pattern, the identification information of the first measuring device 110 or the second measuring device 120, and the power storage. Control for displaying a message indicating a decrease in amount and displaying the message together may be performed on the LCD 909b in FIG.

The CPU 111 of the first measuring device 110 may cause the heat generating unit 115 to generate heat in a pattern in which the first pattern is further shortened as the amount of stored power of the battery decreases.

According to these configurations, the first measuring device 110 generates heat in accordance with a pattern obtained by shortening the first pattern when the charged amount of the storage battery is less than the set amount, and the second measuring device 120 determines that the charged amount of the storage battery is When the amount is less than the set amount, heat is generated according to the pattern obtained by shortening the second pattern. Therefore, the first measuring device 110 and the second measuring device 120 can save power.
