  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
In the environment control system of this embodiment shown in FIG. 1, an air conditioner 3 is installed as an environment control device in a store such as a supermarket, and the air conditioner 3 has a thermal environment (temperature) in the store as a control target value (target temperature). ) Air-conditioning control is performed to match.

  Hereinafter, the operation for setting the control target value according to the customer's request for the thermal environment in the store will be described.

  First, the request input part 1 which receives the opinion with respect to the thermal environment from the customer in a store is provided in the exit of the store. The customer takes the car K (goods carrier) placed at the entrance of the store, puts the desired product in the store into the car K, goes to the cash register, settles the cash at the cash register, and then empty the car K Return to the basket place installed at the store exit and leave the store. In this embodiment, a plurality of basket storage areas provided at the exit of the store are provided corresponding to the customer's opinion on the thermal environment in the store, and the customer responds to the opinion on the thermal environment in the store when leaving the store Return the basket K to the basket storage area. The request input unit 1 in FIG. 1 has a car storage area Xa corresponding to the opinion that the inside of the store is cold, and a car storage area Xb corresponding to the opinion that the inside of the store is hot, and displays “cold” in the car storage area Xa. In the car storage area Xb, “hot” is displayed. That is, if there are many customers who feel “cold”, the number of cars K in the car storage area Xa increases, and if there are many customers who feel “hot”, the number of cars K in the car storage area Xb increases.

  Then, the measurement results of the weight sensors 11a and 11b and the weight sensors 11a and 11b for measuring the total weight of the car K placed in each place are transmitted to the car place Xa and Xb of the request input unit 1 to the controller 2. Communication interfaces 12a and 12b (hereinafter referred to as communication IFs 12a and 12b) are provided.

  Next, the controller 2 includes a sensor communication unit 21, a request information generation unit 22, and a target setting unit 23, and sets a control target value for the air conditioner 3 based on a customer's opinion on the thermal environment. .

  The sensor communication unit 21 receives the measurement results of the weight sensors 11a and 11b from the communication IFs 12a and 12b, and outputs them to the request information generation unit 22.

  The request information generation unit 22 stores the setting table TB1 shown in FIG. 2, and the setting table TB1 associates the content of the opinion about the thermal environment from the customer with respect to each weight sensor as an attribute serving as a comfort index. In this embodiment, the attribute “cold” is associated with the weight sensor 11a, and the attribute “hot” is associated with the weight sensor 11b.

  Then, the request information generation unit 22 performs processing according to the flowchart shown in FIG. First, each measurement result of the weight sensors 11a and 11b is acquired (S1). Next, referring to the setting table TB1, the total results of the attributes “cold” and “hot” are compared based on the measurement results of the weight sensors 11a and 11b (S2). Here, the total result of the attribute “cold” is the weight measured by the weight sensor 11a, and the total result of the attribute “hot” is the weight measured by the weight sensor 11b. Then, if the aggregation result of the attribute “cold” is heavier than the aggregation result of the attribute “hot”, the customer determines that the store feels cold and generates request information “increase store temperature” The generated request information is output to the target value setting unit 23 (S3). On the other hand, if the aggregation result of the attribute “hot” is heavier than the aggregation result of the attribute “cold”, the customer determines that the store feels hot, and generates request information “decrease store temperature” The generated request information is output to the target value setting unit 23 (S4).

  The target value setting unit 23 resets the control target value of the air conditioner 3 based on the request information received from the request information generating unit 22 (S5), and the air conditioner 3 has a new control target for the store's thermal environment. Air conditioning control is performed so as to match the value (S6). When the request information “Increase in-store temperature” is received, the control target temperature is increased by a predetermined temperature (for example, 1 ° C.), and when the request information “Increase in-store temperature” is received, the control target temperature is set to the predetermined temperature. (Eg, 1 ° C.)

  Thereafter, the controller 2 performs the above processing every predetermined time, and resets the control target value of the air conditioner 3 based on the customer's opinion.

  As described above, in this embodiment, opinions about the thermal environment of customers in the store are collected by using the car K that is used as a product carrier in the store and always returned to the car storage area when leaving the store. Therefore, without making the customer aware of the troublesome input of opinions, the loss of opinions is reduced and the customer's opinions on the thermal environment can be reliably collected. Furthermore, since the inexpensive weight sensor 11 (11a, 11b) is used, the system can be constructed at low cost. In addition to the car K, the product carrier may be a cart or the like.

  In addition, two attributes of “cold” and “hot” have been set as attributes that provide comfort indicators for the thermal environment in the store. For example, “cold”, “hot”, “cold can be put up”, “hot can be put up” Five types of “comfort” may be set. In this case, car yard X is also provided at five locations corresponding to each attribute. The number of attributes is not limited to the above, and a plurality of attributes may be set.

  Further, for example, when the total result of the attribute “cold” is 11 kg and the total result of the attribute “hot” is 10 kg, the attribute “cold” having a heavy total result is determined to be the customer's opinion, and the control target value is changed. If the temperature is controlled to increase in the store, the number of customers who feel “hot” may increase rapidly, and the control target value may be changed frequently, resulting in unstable control. Therefore, frequent change of the control target value is prevented by changing the control target value only when the difference between the aggregation result of the attribute “Cold” and the aggregation result of the attribute “Hot” is equal to or greater than the predetermined value. Thus, the control can be stabilized. When the total result of the attribute “Cold” is 11 kg and the total result of the attribute “Hot” is 10 kg, the total result of the attribute “Cold” is 52.4% and the total result of the attribute “Hot” is 21 kg. That is 47.6%, and the ratio difference is 4.8%. If the predetermined ratio to be compared is 10%, the ratio difference is less than the predetermined ratio, so that the control target value is not changed this time.

  In addition, the total results of the attributes “cold” and “hot” may be represented by the number of customers in addition to the weight of the car K. That is, by dividing the weight measured by the weight sensor 11 by the weight per car K, the total result of the attributes “cold” and “hot” can be expressed by the number of customers. When the number of attributes exceeds a predetermined number, environmental control is performed according to the attributes. For example, when the total result of the attribute “cold” is 1 kg and the total result of the attribute “hot” is 5 kg, and the weight per car K is 0.5 kg, the total result of the attribute “cold” is two people, The total result of the attribute “hot” is 10 people. Then, if the predetermined number of people to be compared is 20, the result of counting the larger attribute “hot”: 10 people is less than the predetermined number of people: 20 people, so the control target value is not changed this time.

(Embodiment 2)
The environment control system of the present embodiment is shown in FIG. 4, the same reference numerals are given to the same configurations as those of the first embodiment, and the description will be omitted. The first embodiment is feedback control using a car K which is provided with a request input unit 1 for receiving an opinion on a thermal environment from a customer in the store at the store outlet and is returned from the customer when viewed from the customer. On the other hand, in this embodiment, the request input unit 1 is provided at the entrance of the store, and when viewed from the customer, feedforward control using the car K taken out at the entrance is possible.

  The controller 2 includes an operation unit 24 operated by a store clerk. By operating the operation unit 24, the operation mode of the request information generation unit 22 can be switched to either the feedback control or the feedforward control. Since the operation at the time of feedback control is the same as that of the first embodiment, the description thereof will be omitted, and the operation at the time of feedforward control will be described below.

  First, the request input part 1 which receives the opinion with respect to the thermal environment from the customer in a store is provided in the entrance of the store. The customer takes the car K (goods carrier) placed at the entrance of the store, puts the desired product in the store into the car K, goes to the cash register, settles the cash at the cash register, and then empty the car K Return to the basket place installed at the store exit and leave the store. In this embodiment, a plurality of basket storage areas provided at the entrance of the store are provided corresponding to the customer's opinion on the thermal environment in the store, and the customer responds to the opinion on the thermal environment in the store when entering the store. Take out the basket K from the basket. The request input unit 1 in FIG. 4 has a car storage area Xa corresponding to the opinion that the inside of the store is cold and a car storage area Xb corresponding to the opinion that the inside of the store is hot, and the car storage area Xa displays “cold”. In the car storage area Xb, “hot” is displayed. That is, if there are many customers who feel “cold”, the number of cars K in the car storage area Xa decreases, and if there are many customers who feel “hot”, the number of cars K in the car storage area Xb decreases.

  In the controller 2, the request information generation unit 22 performs processing according to the flowchart shown in FIG. First, each measurement result of the weight sensors 11a and 11b is acquired (S1). Next, referring to the setting table TB1 of FIG. 2, the total results of the attributes “cold” and “hot” are compared based on the measurement results of the weight sensors 11a and 11b (S2). Here, the number of cars K placed in the car storage spaces Xa and Xb is the same in the initial state, and the counting result is expressed by the difference between the weight in the initial state and the measurement result of the weight sensor 11 (11a, 11b). Is done. If the aggregation result of the attribute “cold” is heavier than the aggregation result of the attribute “hot” (that is, if the measurement result of the weight sensor 11a is lighter than the measurement result of the weight sensor 11b), the customer feels that the store is cold. The request information “increase in-store temperature” is generated, and the generated request information is output to the target value setting unit 23 (S3). On the other hand, if the aggregation result of the attribute “hot” is heavier than the aggregation result of the attribute “cold” (that is, if the measurement result of the weight sensor 11b is lighter than the measurement result of the weight sensor 11a), the customer feels that the store is hot. The request information “reducing store temperature” is generated, and the generated request information is output to the target value setting unit 23 (S4).

  The target value setting unit 23 resets the control target value of the air conditioner 3 based on the request information received from the request information generating unit 22 (S5), and the air conditioner 3 has a new control target for the store's thermal environment. Air conditioning control is performed so as to match the value (S6). When the request information “Increase in-store temperature” is received, the control target temperature is increased by a predetermined temperature (for example, 1 ° C.), and when the request information “Increase in-store temperature” is received, the control target temperature is set to the predetermined temperature. (Eg, 1 ° C.)

  Thereafter, the controller 2 performs the above processing every predetermined time, and resets the control target value of the air conditioner 3 based on the customer's opinion.

  As described above, in this embodiment, the customer K in the store is heated by using the basket K that is taken out from the car storage area at the store entrance, used as a product carrier in the store, and always returned to the car storage area when leaving the store. Since opinions about the environment are collected, it is possible to reliably collect opinions about the customer's thermal environment, without making the customer aware of the complexity of inputting opinions, and reducing the loss of opinions.

  Furthermore, in the case of feedback control, customers who shop at the store can collect opinions indicating how the customer wants the thermal environment in the store to visit the store next time. It is possible to collect opinions indicating how customers who want to do the thermal environment in the store from now on. Furthermore, since the operation mode of the request information generation unit 22 can be switched to either the feedback control or the feedforward control by operating the operation unit 24, monitoring control of the thermal environment according to the situation of each store is performed. Can do.

  It should be noted that it is possible to determine whether or not the control target value can be changed by comparing the number of attributes and the total result with a threshold value during feedforward control as well as during feedback control.

(Embodiment 3)
As shown in FIG. 5, the environmental control system of the present embodiment includes a data storage unit 25 in which the controller 2 stores a history of measurement results of the weight sensors 11a and 11b. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 1, and description is abbreviate | omitted.

  The cars K returned to the car storage spaces Xa and Xb of the request input unit 1 provided at the outlet of the store are collected and moved to the entrance of the store when the number increases. When comparing the total results of the attributes “cold” and “hot” based on the measurement results of the weight sensors 11a and 11b, in order to avoid erroneous determination due to a sudden decrease in the measurement results when the car K is collected, The difference between the measurement result of this time and the current measurement result is used, and if the current measurement result is more than a predetermined value compared to the previous measurement result, it is determined that the car K has been recovered, and this time Ignore the measurement result.

  Hereinafter, the operation for setting the control target value based on the difference between the measurement results will be described.

  First, the request information generation unit 22 of the controller 2 is set with a sampling period for acquiring the measurement results of the weight sensors 11a and 11b (for example, a period of 15 minutes), and the data storage unit 25 stores each sampling period. Each measurement result of the acquired weight sensors 11a and 11b is stored. FIG. 6 is a measurement result history table TB2 stored in the data storage unit 25. The measurement result acquisition date and time, the weight sensor, the measurement data, and the increment (increment count) of the current measurement data with respect to the previous measurement data. Each data is stored correspondingly. The increment count is calculated for each of the weight sensors 11a and 11b, and is obtained by subtracting the previous measurement data from the current measurement data.

  Then, the request information generation unit 22 refers to the history table TB2 for each continuous holding time of the control target value (for example, every hour), and calculates the sum of the increment counts for this one hour for each of the weight sensors 11a and 11b. Then, based on the calculated sum of the increment counts, the total results of the attributes “cold” and “hot” are compared to generate request information. If the current measurement result of the weight sensors 11a and 11b is reduced by 1 kg or more compared to the previous measurement result, it is determined that the car K has been recovered, and the current measurement result is ignored and incremented. Do not calculate the count.

  Further, by setting the control target value continuous holding time longer with respect to the sampling period for acquiring the measurement results of the weight sensors 11a and 11b, the store is operated by the operation of the air conditioner 3 using the reset control target value. The next control target value is reset before the thermal environment inside is stabilized, preventing an increase in power consumption and disturbance of comfort due to frequent changes in the control target value, thereby reducing power consumption and improving comfort. Improvements can be made.

  In the history table TB2 of FIG. 6, the request information generation unit 22 calculates the sum of increment counts every hour at 00 minutes, and compares the total results of the attributes “cold” and “hot” based on the calculation result, Generate information. Here, since the measurement result [1 kg] of the weight sensor 11a at 13:00 is reduced by 1 kg or more compared to the measurement result [12 kg] of the weight sensor 11a at 12:45, the car K in the car storage area Xa is collected. Therefore, no data [-] is set in the increment count of the weight sensor 11a at 13:00. At 13:00, the sum [5 + 3 + 4 = 12] of the increment count between 12:15 and 13:00 of the weight sensor 11a is calculated, and the increment count between 12:15 and 13:00 of the weight sensor 11b is calculated. The sum [1 + 2 + 0 + 1 = 4] is calculated.

  Then, the request information generation unit 22 refers to the setting table TB1 in FIG. 3 and compares the total results of the attributes “cold” and “hot” based on the calculated sum of the increment counts of the weight sensors 11a and 11b. Here, the aggregation result of the attribute “cold” is the sum of the increment counts of the weight sensor 11a, and the aggregation result of the attribute “hot” is the sum of the increment counts of the weight sensor 11b. Then, if the aggregation result of the attribute “cold” is heavier than the aggregation result of the attribute “hot”, the customer determines that the store feels cold and generates request information “increase store temperature” The generated request information is output to the target value setting unit 23. On the other hand, if the aggregation result of the attribute “hot” is heavier than the aggregation result of the attribute “cold”, the customer determines that the store feels hot, and generates request information “decrease store temperature” The generated request information is output to the target value setting unit 23.

  The target value setting unit 23 resets the control target value of the air conditioner 3 based on the request information received from the request information generation unit 22, and the air conditioner 3 matches the new control target value in the thermal environment of the store. Air conditioning control is performed. When the request information “Increase in-store temperature” is received, the control target temperature is increased by a predetermined temperature (for example, 1 ° C.), and when the request information “Increase in-store temperature” is received, the control target temperature is set to the predetermined temperature. (Eg, 1 ° C.)

  Thereafter, the controller 2 resets the control target value of the air conditioner 3 based on the request information generated every hour as described above.

  In this way, by using the difference between the previous measurement result of the weight sensors 11a and 11b and the current measurement result, the car due to the recovery of the car K or the like as compared with the case where the measurement results of the weight sensors 11a and 11b are used as they are. It becomes possible to easily cope with the weight change of K. In addition, when the current measurement result has decreased by more than a predetermined value compared to the previous measurement result, the current measurement result is ignored and the incremental count is not calculated. Misjudgment due to a sudden decrease in results can be avoided.

  Further, in the time zone when the number of customers is large, the car K is taken out at the entrance and the car K is returned at the exit frequently. Therefore, the car K is frequently collected, and the request information generating unit 22 performs the above-described operation. Incremental count calculation processing is not performed, and there is a possibility that a large amount of no data [-] may be set in the incremental count of the history table TB2. Therefore, as shown in FIG. 7, a sampling cycle setting table TB3 in which the sampling cycle for acquiring the measurement results of the weight sensors 11a and 11b is associated with the number of customers is stored in the data storage unit 25, and the request information generating unit 22 Referring to the sampling cycle setting table TB3, the sampling cycle corresponding to the number of customers is set. Here, the sampling time becomes shorter as the number of customers increases. Therefore, it is possible to appropriately set the sampling period for acquiring the measurement result according to the number of customers.

  In addition, when the continuous holding time of the control target value is set to a certain time, this continuous holding time is often set longer than the time sufficient for the thermal environment in the store to stabilize, There is a risk that a thermal environment that is less comfortable for the customer will last for a long time. Therefore, as shown in FIG. 8, a continuation holding time setting table TB4 in which the continuation holding time of the control target value corresponds to the number of customers is stored in the data storage unit 25, and the request information generating unit 22 With reference to TB4, the continuous holding time according to the number of customers is set. Here, T in the continuous holding time setting table TB4 is a time sufficient for the temperature in the store to stabilize, and α is an additional time that further considers a margin, and the continuous holding is performed as the number of customers is smaller. The time will be longer. Therefore, the continuous holding time of the control target value can be appropriately set according to the number of customers.

  Here, the current number of customers in the store is based on the weight of all the cars K existing in the store by placing weight sensors that measure the weight of the car K in all the car storage areas including the entrance and exit in the store. The weight obtained by subtracting the weight of the car K existing in all the car storage areas in the store is the weight of the car K carried by the customer in the store, and the car K carried by the customer in the store It can be derived by calculating the number of cars K from the weight and regarding the calculated number of cars K as the number of customers. Alternatively, the number of customers can also be detected by a store visitor counting means (not shown) provided at the entrance of the store.

  Further, there is a method that can appropriately set the sampling period for acquiring the measurement result and the continuous holding time of the control target value even when a means for detecting the current number of customers in the store is not provided. First, the request information generation unit 22 acquires the measurement results of the weight sensors 11a and 11b at predetermined time intervals (for example, every hour) and stores them in the data storage unit 25. FIG. 9A is a measurement result time tabulation table TB5 stored in the data storage unit 25. The date and time when the measurement result is acquired, the weight sensor, the measurement data, and the increment of the current measurement data relative to the previous measurement data ( (Incremental count) data is stored correspondingly. The increment count is calculated for each of the weight sensors 11a and 11b, and is obtained by subtracting the previous measurement data from the current measurement data.

  Then, the request information generation unit 22 calculates the sum of the increment counts of the weight sensors 11a and 11b acquired at the same time, and then calculates the rate of increase for each hour of the sum of the increment counts. In the time tabulation table TB5 of FIG. 9A, the sum of increment counts of 13:00 is 6, the sum of increment counts of 14:00 is 5, the sum of increment counts of 15:00 is 10, and 1 of the sum of increment counts. The rate of increase for each hour is 83% (5/6) and 200% (10/5), respectively.

  As shown in FIG. 9B, the data storage unit 25 stores a sampling period setting table TB6 in which the sampling period for acquiring the measurement results of the weight sensors 11a and 11b is associated with the increment rate of the increment count. The request information generation unit 22 refers to the sampling cycle setting table TB6 and sets a sampling cycle corresponding to the increment rate of the increment count every hour. Here, it is determined that the number of customers has increased as the increment rate of the increment count increases, and the sampling time becomes shorter. Therefore, it is possible to appropriately set the sampling period for acquiring the measurement result according to the number of customers.

  Further, as shown in FIG. 9C, the data storage unit 25 stores a continuous holding time setting table TB7 in which the continuous holding time of the control target value is associated with the increment rate of the increment count. The generation unit 22 refers to the continuous holding time setting table TB7 and sets the continuous holding time according to the increment rate of the incremental count. Here, T in the continuous holding time setting table TB7 is a time sufficient for the temperature in the store to be stabilized, and α is an additional time that further considers a margin, and the increment rate of the incremental count is small. Judging that the number of customers has decreased, the continuous holding time becomes longer. Therefore, the continuous holding time of the control target value can be appropriately set according to the number of customers.

  In the present embodiment, as in the first and second embodiments, it is possible to determine whether or not the control target value can be changed by comparing the feedforward control, the number of attributes, and the total result with a threshold value.

(Embodiment 4)
The environment control system of the present embodiment has the configuration shown in FIG. 5 as in the third embodiment, and the request information generation unit 22 of the controller 2 compares the total results of the attributes “cold” and “hot”. In addition, in order to avoid erroneous determination due to a sudden decrease in the measurement result when the car K is collected, the difference between the previous measurement result and the current measurement result is used as in the third embodiment. However, in the present embodiment, when the current measurement result has decreased by a predetermined value or more compared to the previous measurement result, it is determined that all the cars K have been collected, and the current measurement result The difference from Embodiment 3 is that the increment from 0 is the increment count. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 3, and description is abbreviate | omitted.

  Hereinafter, the operation for setting the control target value based on the difference between the measurement results will be described.

  First, the request information generation unit 22 of the controller 2 is set with a sampling period for acquiring the measurement results of the weight sensors 11a and 11b (for example, a period of 15 minutes), and the data storage unit 25 stores each sampling period. Each measurement result of the acquired weight sensors 11a and 11b is stored. FIG. 10 is a measurement result history table TB8 stored in the data storage unit 25. The measurement result acquisition date / time, weight sensor, measurement data, and increment (increment count) of the current measurement data relative to the previous measurement data are shown. Each data is stored correspondingly. The increment count is calculated for each of the weight sensors 11a and 11b, and is obtained by subtracting the previous measurement data from the current measurement data.

  Then, the request information generation unit 22 refers to the history table TB8 for each continuous holding time of the control target value (for example, every hour), and calculates the sum of the increment counts for this one hour for each of the weight sensors 11a and 11b. Then, based on the calculated sum of the increment counts, the total results of the attributes “cold” and “hot” are compared to generate request information. When the current measurement result of the weight sensors 11a and 11b is reduced by 10 kg or more compared to the previous measurement result, it is determined that all the cars K have been collected, and the current measurement result is 0. The increment from is the increment count.

  In the history table TB8 of FIG. 10, the request information generation unit 22 calculates the sum of increment counts every hour, compares the total results of the attributes “cold” and “hot” based on the calculation result, Generate information. Here, since the measurement result [1 kg] of the weight sensor 11a at 13:00 is 10 kg or more less than the measurement result [12 kg] of the weight sensor 11a at 12:45, the car K in the car storage area Xa is collected. Therefore, the measurement result [1 kg] of the weight sensor 11a at 13:00 is regarded as an increment from the measurement result [0 kg] after collection. Therefore, [1 kg] is set as the increment count of the weight sensor 11a at 13:00. At 13:00, the sum [5 + 3 + 4 + 1 = 13] of the increment count between 12:15 and 13:00 of the weight sensor 11a is calculated, and the increment count of the weight sensor 11b between 12:15 and 13:00 is calculated. The sum [1 + 2 + 0 + 1 = 4] is calculated.

  Next, the request information generation unit 22 refers to the setting table TB1 of FIG. 3 and compares the total results of the attributes “cold” and “hot” based on the calculated sum of the increment counts of the weight sensors 11a and 11b. Request information is generated, and the generated request information is output to the target value setting unit 23. The target value setting unit 23 resets the control target value of the air conditioner 3 based on the request information received from the request information generation unit 22, and the air conditioner 3 matches the new control target value in the thermal environment of the store. Air conditioning control is performed. Thereafter, the controller 2 resets the control target value of the air conditioner 3 based on the request information generated every hour as described above.

  In this way, when the difference between the previous measurement result of the weight sensors 11a and 11b and the current measurement result is used, and the current measurement result has decreased by a predetermined value or more compared to the previous measurement result, By determining that all of the cars K have been collected and setting the increment from 0 as the increment for the current measurement result, it is possible to avoid misjudgment due to a sudden decrease in the measurement result when the car K is collected. . Further, the measurement accuracy is improved by not counting the measurement result when the measurement result is suddenly decreased but by using an increment from 0 as an increment count.

  In the present embodiment, as in the first and second embodiments, it is possible to determine whether or not the control target value can be changed by comparing the feedforward control, the number of attributes, and the total result with a threshold value.

(Embodiment 5)
As shown in FIG. 11, the environmental control system of the present embodiment has reset buttons 5 a and 5 b arranged in the vicinity of the car storage spaces Xa and Xb of the request input unit 1. To the request information generation unit 22. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 3, and description is abbreviate | omitted.

  When the request information generation unit 22 of the controller 2 compares the total results of the attributes “cold” and “hot”, the previous measurement result is avoided in order to avoid erroneous determination due to a sudden decrease in the measurement result when the car K is collected. The difference between the current measurement result and the current measurement result is the same as in the third embodiment. However, in this embodiment, when the reset button 5a or 5b is pressed, it is determined that all the cars K have been collected, and the measurement result of the weight sensor 11a or 11b at the time of pressing is reset to [0 kg].

  First, the request information generation unit 22 of the controller 2 is set with a sampling period for acquiring the measurement results of the weight sensors 11a and 11b (for example, a period of 15 minutes), and the data storage unit 25 stores each sampling period. Each measurement result of the acquired weight sensors 11a and 11b is stored. FIG. 12 is a history table TB9 in which only the measurement result of the weight sensor 11a is stored in the data storage unit 25. The date and time when the measurement result is acquired, the weight sensor, the measurement data, and the increment of the current measurement data relative to the previous measurement data ( (Incremental count) data is stored correspondingly. The increment count is calculated for each of the weight sensors 11a and 11b, and is obtained by subtracting the previous measurement data from the current measurement data.

  Then, the request information generation unit 22 refers to the history table TB9 for each continuous holding time (for example, every hour) of the control target value, and calculates the sum of the increment counts for this one hour for each of the weight sensors 11a and 11b. Then, based on the calculated sum of the increment counts, the total results of the attributes “cold” and “hot” are compared to generate request information.

  In the history table TB9 of FIG. 12, the request information generating unit 22 calculates the sum of increment counts every hour, compares the total results of the attributes “cold” and “hot” based on the calculation result, Generate information. When the store clerk collects the car K in the car storage area Xa at 12:50 and presses the reset button 5a, a press signal is output to the request information generation unit 22 of the controller 2. The request information generation unit 22 that has received the press signal from the reset button 5a determines that all the cars K in the car storage area Xa have been collected, and the measurement result [0 kg] of the weight sensor 11a in the history table TB9 is incremented. Set [0kg]. Subsequent request information generation processing and control target value resetting processing are the same as those in the third embodiment, and a description thereof will be omitted.

  In this way, when the reset button 5 (5a, 5b) is pressed after the car K is collected, the collection of the car K can be reliably detected, and a misjudgment due to a sudden decrease in the measurement result when the car K is collected. It can certainly be avoided.

  Alternatively, by pressing the reset button 5 (5a, 5b) twice before and after collecting the car K, the car K is more reliably detected and measured by the weight sensor 11 (11a, 11b). The result can be obtained with high accuracy.

  For example, when the store clerk presses the reset button 5 a of the car storage area Xa before the car K is collected (12:50), a press signal is output to the request information generation unit 22 of the controller 2. Upon receiving the first press signal from the reset button 5a, the request information generation unit 22 of the controller 2 acquires the measurement result from the weight sensor 11a, and the measurement result [14kg] of the weight sensor 11a in the history table TB10 of FIG. Set the increment count [2kg]. Here, since the measurement result acquired from the weight sensor 11a by the pressing signal of the reset button 5a has not decreased compared to the previous measurement result, the request information generation unit 22 can determine that the measurement result is before collection.

  When the store clerk collects the car K in the car storage space Xa (12:51) and then presses the reset button 5a again, a press signal is output to the request information generation unit 22 of the controller 2. The request information generation unit 22 of the controller 2 that has received the second press signal from the reset button 5a determines that the car K in the car storage area Xa has been collected, acquires the measurement result from the weight sensor 11a, and in the history table TB10 The measurement result [0 kg] of the weight sensor 11a and the increment count [0 kg] are set.

  However, in the method of detecting the recovery of the car K by pressing the reset button 5 (5a, 5b) twice before and after the recovery of the car K as described above, the store clerk presses the reset button 5. There is a risk of forgetting to push because it depends on the behavior. Therefore, the request information generation unit 22 of the controller 2 performs an error process when the reset button 5 is forgotten to be pressed by performing a comparison process with the previous measurement result when the measurement result is acquired from the weight sensor 11.

  For example, if the user forgets to press the reset button 5a before collecting the car K placed in the car storage area Xa, as shown in the history table TB10 of FIG. Measurement results before collection cannot be obtained. And when the measurement result is acquired from the weight sensor 11a by the pressing signal of the reset button 5a pressed at 12:51, the acquired measurement result is reduced compared to the previous measurement result. It is determined that the measurement result is. Thus, it is determined that the car K in the car storage area Xa has been collected, and the measurement result [0 kg] and the increment count [0 kg] of the weight sensor 11a are set in the history table TB10.

  If the user forgets to press the reset button 5a after collecting the car K placed in the car storage area Xa, the request information generating unit 22 collects from the weight sensor 11a as shown in the history table TB10 of FIG. Since the subsequent measurement result cannot be acquired and the measurement result is acquired from the weight sensor 11a at 13:00, which is the next sampling timing, the acquired measurement result is reduced compared to the previous measurement result. Judged as the measurement result after collection. Thus, it is determined that the car K in the car storage area Xa has been collected, and the increment count of 13:00 stores the increment from [0 kg] in the history table TB10.

  In the present embodiment, as in the first and second embodiments, it is possible to determine whether or not the control target value can be changed by comparing the feedforward control, the number of attributes, and the total result with a threshold value.

(Embodiment 6)
As shown in FIG. 15, the environmental control system of the present embodiment has indicator lights 6 a and 6 b arranged in the vicinity of the car storage spaces Xa and Xb of the request input unit 1, and the indicator lamp 6 a is provided by a notification unit 26 provided in the controller 2. , 6b are controlled to be lit. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 3, and description is abbreviate | omitted.

  First, the notification unit 26 of the controller 2 refers to the history table TB2 in the data storage unit 25 and monitors each measurement result of the weight sensors 11a and 11b. And when each measurement result of the weight sensors 11a and 11b exceeds a predetermined weight, it is determined that there are too many cars K placed in the car storage spaces Xa and Xb, and it is determined that there are too many cars K. The indicator lamp 6a or 6b provided in the vicinity of the car storage area is turned on. The store clerk collects the car K placed in the car yard Xa when the indicator light 6a is turned on, and collects the car K placed in the car yard Xb when the indicator light 6b is lit.

  Alternatively, the notification unit 26 is configured by communication means that connects to a wide-area communication network such as the Internet and performs packet communication with a mobile phone carried by a store clerk, and each of the cars K placed in the car storage locations Xa and Xb. If it is determined that the number is too large, an e-mail indicating that the number of cars K in the car storage area is too large may be created and notified to the clerk by e-mail.

  If the car K in the car storage area is left uncollected for a long time, it becomes difficult for the customer to return the car K, and the customer may return it to the car storage area with a small number of cars K regardless of his / her opinion. The accuracy of the generated request information is adversely affected. However, in the present embodiment, since the store clerk is informed that the number of cars K in the car storage area is too large and is quickly collected, it is possible to prevent the accuracy of the generated demand information from being lowered.

(Embodiment 7)
As shown in FIG. 16, the environmental control system of the present embodiment arranges the display unit 7 in the vicinity of the car storage spaces Xa and Xb of the request input unit 1, and the display control unit 27 provided in the controller 2 controls the display unit 7. The display content is controlled. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 3, and description is abbreviate | omitted.

  First, the display control unit 27 of the controller 2 acquires information on the next sampling time (that is, the reset time of the control target value) and information on the total result of the customer's opinion from the request information generation unit 22. Is displayed on the display unit 7. As shown in FIG. 17, the display unit 7 displays the reset time of the next control target value and the tabulated result of the customer's opinions at the present time. By viewing the display on the display unit 7, the customer is conscious of seriously reflecting his / her opinion on the thermal environment in the store when the car K is returned, and the accuracy of the generated request information is improved.

  In addition, although the environment control system of each said embodiment illustrated the structure which performs air-conditioning control so that the temperature in a store corresponds to target temperature, humidity, illumination, etc. may be sufficient as the environment in a store What is necessary is just the structure which produces | generates request information using the request input part 1 using goods carriers, such as the basket K, and controls the environment in these stores.
