This comparison is preferably made by paying attention to only the local area of the face, for example, the eye and its peripheral part. In this case, only the eye area image data around the eye including the eye in the face area image data is extracted.

Subsequently, the central management device 70 reads out preset face area model data and eye area model data indicating a range where the eyes exist from the face area model data (model data reading means) from the built-in database. Function as.
Here, each size of model data is prepared, and data of a large number of faces (race, gender, age, glasses use, etc. based on anthropological considerations) is prepared.

  Subsequently, the centralized management device 70 calculates a ratio by comparing the face area image data and the eye area image data, and calculates a ratio by comparing the face area model data and the eye area model data (ratio calculation). Function).

  Specifically, the correlation is calculated by comparing all face area data existing in the same image data with the face area model data. Since the face area image data and the face area model data have different image sizes (the number of horizontal dots in the face size × the number of vertical dots), for example, first, the eye axis of the face area image data and the face area model data The correlation is obtained by comparing the coordinates with each other, and the correlation for the face region is obtained by shifting the coordinates vertically and horizontally to the left and the bottom. Then, the ratio is calculated by comparing the face area image data and the eye area image data at a position where the correlation is high, and the ratio is calculated by comparing the face area model data and the eye area model data. In this case, the ratio is calculated as many times as the number of face area image data extracted by the face area extracting means.

  Subsequently, the centralized management device 70 functions as means for reading out operation data for each person from the database in accordance with the estimated number of persons data calculated by the estimation means. The operation data for each number of persons is data that is divided into a plurality of stages within a range of preset number of recognized persons, and controls the air conditioning equipment through the respective control sensors so as to be different depending on the plurality of stages.

  Specifically, the operation data by number of people is not only classified by season and time of day, but also according to changes in the number of visitors such as large-scale stores etc., the temperature and humidity of the air conditioning environment as indicators and the number of visitors as parameters. Recognize people based on the data, and correspond to the number of recognized people data in multiple stages, for example, “very crowded”, “crowded”, “normal”, “vacant”, “rattle”, etc. It is set in advance. The operation of the air conditioning equipment is controlled according to the operation data classified by the number of people, so that troubles such as correspondence of employees and air conditioning personnel can be saved.

  In addition, the operation data by number of people is registered in the centralized management device so that multiple air conditioning facilities are grouped in advance and scheduled operation is performed by group, or the centralized management device so that each group is sequentially scheduled at set time intervals. Or by adding the individual functions described above, the centralized management device 70 may monitor the state of the air conditioning equipment and control the on / off contact operation. In order to cope with an unexpected situation, it is possible to forcibly switch to manual operation or stop via a remote controller or the like.

It functions as means for performing (operation control means).

  Thus, by performing air-conditioning control based on the recognized number-of-persons data based on the image data, it is possible to save energy by providing additional functions such as a ventilation mode and outdoor unit watering while enabling efficient operation of the air-conditioning equipment. In particular, it is easy for business operators and consumers to introduce and improve usability, and it is possible to realize energy-saving operation of an air-conditioning facility with a large proportion of power consumption efficiently and at low cost.

The other camera 60 is disposed in the customer entrance / exit area of the large-scale customer collection facility, and photographs the direction in the facility (second camera).

The central management device 70 functions as means (first person recognition means) for recognizing a person based on image data from the first camera 60 and generating visitor number data for the number of recognized persons.
The central management device 70 functions as means (second number recognition means) for recognizing a person based on image data from the second camera 60 and generating exit number data for the number of recognized persons.

The air conditioning control system 1 is a system constructed across a room where the centralized management device 70 is installed and a plurality of rooms A to D.

Next, the air conditioning control system 1 that has higher functions so that demand control can be performed in addition to the above control will be described. The demand control is performed using the sensor device 40 described above. The electric energy sensor 41 is a sensor that measures the electric energy of 6.6 KV receiving / transforming power for each room. The temperature sensor 42 and the humidity sensor 43 are a plurality of sensors installed in each room. The DIO sensor 44 is a plurality of sensors installed in each room. The central management device 70 and each server device 30 with a protocol conversion function are communicably connected via a backbone communication line 22 such as a LAN line.

  Furthermore, an individual function for saving energy while reducing discomfort is added to the above-described air conditioner condition monitoring and operation control. Such a function will be described with reference to the drawings. FIG. 4 is an explanatory diagram of an auxiliary cooling device for an outdoor unit, and FIG. 5 is an explanatory diagram of demand control using the auxiliary cooling device. The power demand is used as an index, and management is performed using an auxiliary cooling device that sprays water to the outdoor unit. The auxiliary cooling device 80 of the outdoor unit has a built-in watering device. As shown in FIG. 4, the watering device includes a nozzle 81 for spraying water on the heat exchanger 52 of the outdoor unit 51 and the nozzle 81. The mounting frame 82 is supported, and the mounting frame 82 can be attached to and detached from the outdoor unit 51.

  The auxiliary cooling device 80 has a control unit (not shown) that controls the amount of water supplied to the nozzles 81 in stages. The amount of water supplied is controlled by the DO unit of the DIO sensor 44, and the amount of water supplied through the DI unit. Is connected to get. The centralized management device 70 measures the amount of 6.6 KV power reception / transformation for each building in the plurality of buildings through the plurality of power amount sensors 41, and calculates a demand value for each building in the plurality of buildings from these power amount measurement data. And demand control is performed for every building of several buildings. Assuming that a demand value as shown in FIG. 5 is obtained for a certain building, first, the centralized management device 70 operates the air conditioning equipment (PAC 50) when it exceeds the set first demand alarm level. Is switched to the linked operation with the auxiliary cooling device 80, and in addition to the centralized management by demand control, the cooling start command is output to the auxiliary cooling device 70 to forcibly spray water to the control unit of the outdoor unit water spraying device. In addition to commanding, it functions as means for monitoring the state of the air conditioning equipment (PAC50) and controlling the on / off contact operation. The control unit of the auxiliary cooling device 80 intermittently sprinkles water from the nozzle 81 according to the command. As apparent from FIG. 5, the tendency of the demand value to increase during watering is suppressed, and a situation in which the demand value immediately exceeds the upper limit is avoided.

  Further, when the demand value exceeds the set first alarm level and further exceeds the second alarm level, the centralized management device 70 stops the operation of the auxiliary cooling device 80 and operates the indoor unit of the PAC 50 in the air blowing mode. It functions as a means for performing air conditioner condition monitoring and on / off contact operation control so as to switch to forced schedule operation. As is apparent from FIG. 5, the tendency of the demand value to increase during the air blowing mode operation is suppressed, and a situation in which the demand value immediately exceeds the upper limit is avoided.

  It is assumed that a plurality of air conditioning facilities are grouped in advance and registered in the centralized management device 70 so that the forced scheduled operation is performed for each group. In the centralized management device 70, each group is sequentially subjected to forced scheduled operation at set time intervals. As described above, air conditioner condition monitoring and on / off contact operation control may be performed. For example, in this embodiment, one PAC 50 is combined into one group, and the PAC 1 in FIG. 1, the PAC 2 in B, and the PAC 3 in C are sequentially switched to the air blowing mode to suppress the demand increase rate and the demand exceeds the setting. I am trying not to. By performing these controls, the effect that the demand falls within the set range can be obtained. Such an air conditioning control system 1 may be used.

  Next, other functions will be described with reference to the drawings. FIG. 6 is an explanatory diagram of PAC centralized control using fluctuation control together with the indoor temperature as an index. In addition to the above-described embodiments described above, the following functions are further provided. In this fluctuation control, the room temperature is measured, and the set temperature is changed frequently by automatic control to save energy. When the measured temperature reaches the standard set temperature during package air conditioner operation, the set temperature is raised to the set temperature for fluctuation after the set time has elapsed during cooling. However, an upper limit temperature for fluctuation is provided so as not to exceed the upper limit temperature. After the measured temperature reaches the set temperature for fluctuation, the set temperature is returned to the standard temperature after the set recovery time has elapsed. Conversely, during heating operation, setting control is performed to lower the fluctuation set temperature. The outline of the process is like this.

First, the central management device 70 functions as a means for registering standard set temperature data. In FIG. 6, it is set to 24 ° C.
The centralized management device 70 functions as means for calculating the set temperature data for fluctuation and the upper limit temperature data for fluctuation from the standard set temperature data. In FIG. 6, the set temperature for fluctuation is set to 26 ° C., + 2 ° C. from the standard set temperature data, and the upper limit temperature for fluctuation is set to 28 ° C., + 4 ° C. from the standard set temperature data.
The centralized management device 70 is configured to adjust the air conditioning equipment so that the indoor temperature does not exceed the upper limit temperature for fluctuation from the indoor temperature measurement data, so that the temperature changes minutely between the standard set temperature and the set temperature for fluctuation at regular intervals. It functions as means for monitoring the state of the PAC 50) and controlling the on / off contact operation.
By doing in this way, energy saving can be aimed at.

  Next, other functions will be described with reference to the drawings. FIG. 7 is an explanatory diagram of PAC centralized control using the outside air temperature and the outside air humidity. In addition to the above-described embodiments described above, the following functions are further provided. Here, the temperature sensor 42 is installed outdoors to output temperature measurement data of outside air, and the humidity sensor 43 is installed outdoors to output humidity measurement data of outside air. To do. FIG. 7 shows PAC status monitoring and operation control. The discomfort index of the outside air is calculated from the outside air temperature and the outside air humidity, and the outside air is taken in from the discomfort index when it is a condition that a person feels comfortable, that is, when the outside air is more comfortable than the room. Make air conditioning operational. Under comfortable conditions, the PAC is changed to the air blowing mode.

  Here, the discomfort index is an index that quantitatively represents the heat of summer and is given by the following equation.

[Equation 1]
Discomfort index (DI) = 0.81T + 0.01U (0.99T-14.3) +46.3
T: Outside air temperature (° C)
U: Relative humidity of outside air (%)

  The discomfort index and the body temperature are as follows. Less than 55, cold at 55-60, chilly at 60-65, no feeling at 60-65, pleasant at 65-70, not hot at 70-75, slightly hot at 75-80, 80-85 hot and sweaty, 85 That's why it's hot and irresistible. It is said that 10% of the population becomes uncomfortable when the discomfort index exceeds 75, and everyone becomes uncomfortable when it exceeds 80.

First, the central management device 70 functions as a means for calculating the discomfort index from the temperature measurement data and humidity measurement data of the outside air.
When the discomfort index is within the set range, for example, when the discomfort index is 60 to 75 with the above numerical value, the centralized management device 70 switches the air-conditioning equipment to the air blowing mode operation that takes in outside air, and the discomfort index is not within the set range. For example, when the discomfort index exceeds 75 or the discomfort index falls below 60, the air conditioner functions as a means for monitoring the state of the air conditioner and controlling the on / off contact operation so as to switch to the normal mode operation. Here, when the discomfort index exceeds 75, the normal mode operation by cooling may be performed, or when the discomfort index is less than 60, the normal mode operation by heating may be performed.

  From the outside air temperature and outside air humidity measured by a demand controller (not shown) separately provided here, the centralized management device 70 determines whether control is possible and transmits a control signal to the terminal device of each building, and makes the PAC 50 a blower mode. Change to At that time, remote control operation of the PAC 50 is prohibited from the user's hand, and the user cannot arbitrarily change to the on / off command or the cooling / heating mode.

  Next, other functions will be described with reference to the drawings. FIG. 8 is an explanatory diagram of alarm centralized control based on a time setting schedule as automatic stop cancellation control. In addition to the above-described embodiments described above, the following functions are further provided. FIG. 8 shows the state monitoring and operation control of the alarm central control. For the purpose of saving energy by preventing the user from forgetting to turn off the PAC 50, control is performed by setting the automatic stop time and the scheduled time for releasing the operation of the local remote controller. The PAC 50 on / off command (On: automatic stop release, Off: stop (on / off at most 3 times a day)) can be made by setting a schedule at a specified time in each room remote controller. The schedule can be set for each group. If an operation command is issued by the local remote controller during the off time, the operation stops after the set time has elapsed. This function allows time setting separately for each group after the first operation and after the second and subsequent operations.

  In this way, by collecting the air conditioner contact operation data from the air conditioner condition monitoring and operation control sensor together with the electric energy measurement data and the environment measurement data, fluctuation control, while enabling efficient operation of the air conditioner, Additional functions, such as a ventilation mode and outdoor unit watering, are provided for further energy saving. And it makes it easy to construct the air conditioning control system of the present invention such as reduction of communication line laying work and compatibility with existing building air conditioning equipment.

  In such an air conditioning control system of the present invention, in a large-scale store or the like, if the number of visitors fluctuates greatly, for example, during the time when there are few visitors in summer, the control unit of the sprinkler of the outdoor unit is compulsory. In addition to giving watering instructions, air conditioner (PAC) status monitoring and on / off contact operation control are performed, and conversely, during winter time when visitors are crowded, outside air is taken in as a ventilation mode operation. Thus, the amount of power used is reduced, and the increasing tendency of the demand value is suppressed.

  In addition to new buildings, it is easy to introduce operators and customers who have buildings with old facilities, and it is easy to introduce and improves usability. Energy-saving operation of a large proportion of air conditioning equipment can be realized efficiently and at low cost. The present invention can efficiently save energy even when the number of visitors varies greatly depending on the time of day.
