Description

集中監視装置及び監視システムCentralized monitoring device and monitoring system
　本発明は、空調冷熱機器を管理する集中監視装置及びその集中監視装置を備える監視システムに関する。 The present invention relates to a centralized monitoring device that manages air-conditioning / cooling equipment and a monitoring system including the centralized monitoring device.
　建物内の温度は、建物に設置されたドアの開閉等の人的要因又は天候の変化等の外的要因によって変化する。例えば、食料品等を運搬する運送用トラック等の車両が、空調冷熱機器に冷却される冷凍倉庫の扉の前に設置されたトラックヤードに到着した後、冷凍倉庫の扉が開かれて、荷物の搬入搬出作業が行われる。その際、開かれた冷凍倉庫内に外気が流入して、冷凍倉庫内の温度が上昇する虞がある。そして、これにより、冷凍倉庫内に保管された食料品等の品質が劣化する虞がある。 The temperature inside the building changes depending on human factors such as opening and closing of doors installed in the building and external factors such as weather changes. For example, after a vehicle such as a truck for transporting foods arrives at a truck yard installed in front of the door of a freezer warehouse that is cooled by air-conditioning / cooling equipment, the door of the freezer warehouse is opened, Carry-in / carry-out work is performed. At that time, outside air may flow into the open freezer warehouse and the temperature in the freezer warehouse may rise. And thereby, there exists a possibility that the quality of the foodstuff etc. which were stored in the freezer warehouse may deteriorate.
　これを解消することを目的として、従来より、冷凍倉庫内の設定温度を手動で変更して、冷凍倉庫内の温度を予め低下させる集中監視装置が知られている。また、特許文献１には、車両の現在位置の外気環境に基づいて空気取り入れ口であるインテークドアの開閉状態を切り替える車両用空調装置が開示されている。 In order to solve this problem, a centralized monitoring device is known in which the set temperature in the freezer warehouse is manually changed to lower the temperature in the freezer warehouse in advance. Patent Document 1 discloses a vehicle air conditioner that switches an open / close state of an intake door that is an air intake port based on an outside air environment at a current position of the vehicle.

　しかしながら、従来の集中監視装置は、荷物の搬入搬出作業が行われる度に、冷凍倉庫内の温度を手動で設定しなければならず、煩わしい。また、特許文献１は、車両に設けられた車両用空調装置に関するものであり、車両とは別に設置された空調冷熱機器の温度設定については何ら配慮されていない。 However, the conventional centralized monitoring device is troublesome because the temperature in the freezer warehouse must be manually set every time when loading and unloading work is performed. Patent Document 1 relates to a vehicle air conditioner provided in a vehicle, and does not give any consideration to the temperature setting of an air conditioning cooling / heating device installed separately from the vehicle.
　本発明は、上記のような課題を背景としてなされたもので、冷凍倉庫の温度が上昇することを抑制する集中監視装置及びその集中監視装置を備える監視システムを提供するものである。 The present invention has been made against the background of the above problems, and provides a centralized monitoring device that suppresses an increase in the temperature of a freezer warehouse and a monitoring system including the centralized monitoring device.
　本発明に係る集中監視装置は、車両と共に移動する移動体端末から、空調冷熱機器によって冷却される冷凍倉庫に車両が到着する到着残り時間の情報、或いは、到着残り時間の演算に用いられる車両の現在位置の情報を取得する受信部と、受信部で取得された情報から得られる到着残り時間に基づいて、空調冷熱機器の温度設定値を変更する制御部と、を備える。 The centralized monitoring apparatus according to the present invention provides information on the remaining arrival time of a vehicle that arrives at a refrigeration warehouse cooled by an air conditioning / cooling device from a mobile terminal that moves with the vehicle, or the vehicle used for calculating the remaining arrival time. A receiving unit that acquires information on the current position, and a control unit that changes the temperature setting value of the air-conditioning / cooling device based on the remaining arrival time obtained from the information acquired by the receiving unit.
　本発明によれば、制御部が、到着残り時間に基づいて、空調冷熱機器の温度設定値を変更する。このため、冷凍倉庫の温度が上昇することを抑制することができる。 According to the present invention, the control unit changes the temperature setting value of the air-conditioning cooling / heating device based on the remaining arrival time. For this reason, it can suppress that the temperature of a freezer warehouse rises.

　本実施の形態１は、移動体端末２が到着時間演算部２５を有しており、集中監視装置１において到着残り時間を演算する必要がない。このため、集中監視装置１の負荷を軽減することができる。なお、集中監視装置１は、到着残り時間を演算する機能を有していてもよい。この場合、集中監視装置１は、車両の現在位置の情報に基づいて、到着残り時間を演算する。なお、冷凍倉庫４ａが複数存在する場合は、集中監視装置１は、目的地情報も取得して、現在位置と目的地情報とに基づいて、夫々の車両の到着残り時間を演算する。これにより、移動体端末２において到着残り時間を演算する必要がない。 In the first embodiment, the mobile terminal 2 has the arrival time calculation unit 25, and the centralized monitoring device 1 does not need to calculate the remaining arrival time. For this reason, the load of the centralized monitoring apparatus 1 can be reduced. The centralized monitoring device 1 may have a function of calculating the remaining arrival time. In this case, the centralized monitoring device 1 calculates the remaining arrival time based on information on the current position of the vehicle. When there are a plurality of frozen warehouses 4a, the central monitoring apparatus 1 also acquires destination information and calculates the remaining arrival time of each vehicle based on the current position and the destination information. Thereby, it is not necessary to calculate the remaining arrival time in the mobile terminal 2.

When the determination unit 41 determines that there is a vehicle whose destination is the refrigerated warehouse 4a, the control unit 36 selects the refrigeration set as the destination based on the remaining arrival time acquired by the arrival time receiving unit 32. The temperature set value of the air-conditioning cooling / heating device 4 that cools the warehouse 4a is changed. Note that the determination means 41 determines, for example, whether or not there is at least one vehicle having the refrigeration warehouse 4a as the destination. When there are a plurality of frozen warehouses 4a as destinations, the destination information includes information indicating which one of the frozen warehouses 4a is the destination.
　判定手段４２は、受信部３８で取得された情報から得られる到着残り時間が、閾値時間よりも短いか否かを判定するものである。具体的には、判定手段４２は、到着時間受信部３２で取得された到着残り時間が、閾値時間よりも短いか否かを判定する。ここで、閾値時間は、例えば入力部３１によって適宜変更することができる。閾値時間は、例えば、１０分、１５分、３０分等である。なお、複数の車両が存在する場合、判定手段４２は、到着時間受信部３２で取得された複数の到着残り時間の夫々が、閾値時間よりも短いか否かを判定する。 The determination means 42 determines whether the remaining arrival time obtained from the information acquired by the receiving unit 38 is shorter than the threshold time. Specifically, the determination unit 42 determines whether or not the remaining arrival time acquired by the arrival time receiving unit 32 is shorter than the threshold time. Here, the threshold time can be appropriately changed by the input unit 31, for example. The threshold time is, for example, 10 minutes, 15 minutes, 30 minutes, or the like. When there are a plurality of vehicles, the determination unit 42 determines whether each of the plurality of remaining arrival times acquired by the arrival time receiving unit 32 is shorter than the threshold time.
　計測手段４３は、判定手段４２において到着残り時間が閾値時間よりも短いと判定された車両の台数を計測するものである。そして、計測手段４３は、予め決められた間隔毎に車両の台数を計測する。 The measuring means 43 measures the number of vehicles determined by the determining means 42 that the remaining arrival time is shorter than the threshold time. And the measurement means 43 measures the number of vehicles for every predetermined space | interval.
　比較手段４４は、計測手段４３において計測された車両の台数が、計測手段４３において直前に計測された車両の直前台数と相違するか否かを判定するものである。ここで、直前に計測された車両の直前台数とは、現状の制御の直前の制御において計測された車両の台数である。 The comparing means 44 determines whether or not the number of vehicles measured by the measuring means 43 is different from the immediately preceding number of vehicles measured immediately before by the measuring means 43. Here, the immediately preceding number of vehicles measured immediately before is the number of vehicles measured in the control immediately before the current control.
　温度低下手段４５は、判定手段４２において到着残り時間が閾値時間よりも短いと判定された場合、空気冷熱機器の温度設定値を低下させるものである。なお、複数の車両が存在する場合、温度低下手段４５は、判定手段４２において少なくとも１台の車両の到着残り時間が閾値時間よりも短いと判定された場合、空気冷熱機器の温度設定値を低下させる。ここで、温度設定値から低下させる温度シフト値は、例えば入力部３１によって適宜変更することができる。 The temperature lowering means 45 lowers the temperature set value of the air-cooled equipment when the determining means 42 determines that the remaining arrival time is shorter than the threshold time. When there are a plurality of vehicles, the temperature lowering means 45 lowers the temperature set value of the air-cooled equipment when the determining means 42 determines that the remaining arrival time of at least one vehicle is shorter than the threshold time. Let Here, the temperature shift value to be lowered from the temperature set value can be appropriately changed by, for example, the input unit 31.
　また、具体的には、温度低下手段４５は、温度設定値を、計測手段４３において計測された車両の台数に基づいて決められた温度設定値に変更する。このように、温度シフト値は、計測手段４３において計測された車両の台数によって変更されてもよい。温度シフト値は、例えば、計測された車両が１台である場合、Δｔ１であり、計測された車両が２台である場合、Δｔ２であり、計測された車両が３台である場合、Δｔ３である。なお、例えば、Δｔ１＜Δｔ２＜Δｔ３であり、車両の台数が多いほど温度シフト値を大きくしているが、これに限らず、いずれも同じシフト値としてもよい。 More specifically, the temperature lowering means 45 changes the temperature set value to a temperature set value determined based on the number of vehicles measured by the measuring means 43. As described above, the temperature shift value may be changed depending on the number of vehicles measured by the measuring unit 43. The temperature shift value is, for example, Δt1 when there is one measured vehicle, Δt2 when there are two measured vehicles, and Δt3 when there are three measured vehicles. is there. Note that, for example, Δt1 <Δt2 <Δt3, and the temperature shift value is increased as the number of vehicles is increased. However, the present invention is not limited to this, and both may have the same shift value.
　更に具体的には、温度低下手段４５は、比較手段４４において車両の台数が車両の直前台数と相違すると判断された場合、計測手段４３において計測された車両の台数に基づいて、温度設定値を低下させる。 More specifically, the temperature lowering unit 45 determines the temperature setting value based on the number of vehicles measured by the measuring unit 43 when the comparing unit 44 determines that the number of vehicles is different from the immediately preceding number of vehicles. Reduce.
　第１の復帰手段４６は、判断手段４１において冷凍倉庫４ａを目的地とする車両が存在しないと判定された場合、空調冷熱機器４の温度設定値を例えば通常の温度設定値である初期値に復帰するものである。これは、例えば、車両の搬入搬出作業が終了し、移動体端末２における車両の目的地情報が消去される場合が該当する。 When it is determined by the determination means 41 that there is no vehicle whose destination is the refrigerated warehouse 4a, the first return means 46 sets the temperature setting value of the air-conditioning cooling / heating device 4 to an initial value that is a normal temperature setting value, for example. It will return. This corresponds to, for example, the case where the vehicle loading / unloading work is completed and the vehicle destination information in the mobile terminal 2 is deleted.
　第２の復帰手段４７は、判定手段４２において到着残り時間が閾値時間以上であると判定された場合、空調冷熱機器４の温度設定値を初期値に復帰するものである。なお、複数の車両が存在する場合、第２の復帰手段４７は、判定手段４２において全ての車両の到着残り時間が閾値時間以上であると判定された場合、空調冷熱機器４の温度設定値を初期値に復帰する。 The second return means 47 is for returning the temperature setting value of the air-conditioning cooling / heating device 4 to the initial value when the determination means 42 determines that the remaining arrival time is equal to or greater than the threshold time. When there are a plurality of vehicles, the second return means 47 determines the temperature setting value of the air-conditioning cooling / heating device 4 when the determination means 42 determines that the remaining arrival time of all the vehicles is equal to or greater than the threshold time. Returns to the initial value.
　維持手段４８は、比較手段４４において車両の台数が車両の直前台数と同じと判断された場合、温度設定値を現状維持のまま変更しない。比較手段４４において車両の台数が車両の直前台数と同じと判断された場合、温度設定値は、直前の制御において既に低下しているため、現状の制御において温度設定値を低下させる必要はない。 When the comparison unit 44 determines that the number of vehicles is the same as the immediately preceding number of vehicles, the maintenance unit 48 does not change the temperature setting value while maintaining the current state. When the comparison unit 44 determines that the number of vehicles is the same as the immediately preceding number of vehicles, the temperature set value has already decreased in the immediately preceding control, and therefore it is not necessary to decrease the temperature set value in the current control.
　図６は、本発明の実施の形態１における温度シフト値を示す表である。図６に示すように、負荷側機器９ａが設けられた冷凍エリア１０ａには、３個のトラックヤード１１，１２，１３が設けられており、閾値時間は１５分に設定されている。そして、温度シフト値は、計測された車両が０台である場合、現状維持のまま変更せず、計測された車両が１台である場合、Δｔ１、計測された車両が２台である場合、Δｔ２、計測された車両が３台である場合、Δｔ３である。また、負荷側機器９ｂが設けられた冷凍エリア１０ｂには、２個のトラックヤード１４，１５が設けられており、閾値時間は１０分に設定されている。そして、温度シフト値は、計測された車両が０台である場合、現状維持のまま変更せず、計測された車両が１台である場合、Δｔ１、計測された車両が２台である場合、Δｔ２である。 FIG. 6 is a table showing temperature shift values in Embodiment 1 of the present invention. As shown in FIG. 6, in the freezing area 10a where the load side device 9a is provided, three truck yards 11, 12, 13 are provided, and the threshold time is set to 15 minutes. Then, the temperature shift value is not changed while maintaining the current state when the number of measured vehicles is zero, Δt1, when the number of measured vehicles is two, when the number of measured vehicles is one, Δt2 is Δt3 when there are three measured vehicles. In addition, two truck yards 14 and 15 are provided in the refrigeration area 10b in which the load side device 9b is provided, and the threshold time is set to 10 minutes. Then, the temperature shift value is not changed while maintaining the current state when the number of measured vehicles is zero, Δt1, when the number of measured vehicles is two, when the number of measured vehicles is one, Δt2.
　更に、負荷側機器９ｃが設けられた冷凍エリア１０ｃには、１個のトラックヤード１６が設けられており、閾値時間は３０分に設定されている。そして、温度シフト値は、計測された車両が０台である場合、現状維持のまま変更せず、計測された車両が１台である場合、Δｔ１である。更にまた、負荷側機器９ｄが設けられた冷凍エリア１０ｄには、１個のトラックヤード１７が設けられており、閾値時間は３０分に設定されている。そして、温度シフト値は、計測された車両が０台である場合、現状維持のまま変更せず、計測された車両が１台である場合、Δｔ１である。 Furthermore, one truck yard 16 is provided in the freezing area 10c where the load side device 9c is provided, and the threshold time is set to 30 minutes. The temperature shift value is Δt1 when the number of measured vehicles is zero and is not changed while maintaining the current state, and when the number of measured vehicles is one. Furthermore, one truck yard 17 is provided in the freezing area 10d where the load side device 9d is provided, and the threshold time is set to 30 minutes. The temperature shift value is Δt1 when the number of measured vehicles is zero and is not changed while maintaining the current state, and when the number of measured vehicles is one.
　図７は、本発明の実施の形態１に係る集中監視装置１の動作を示すフローチャートである。次に、本実施の形態１に係る集中監視装置１の動作について説明する。図７に示すように、制御が開始されると、先ず、判断手段４１によって、端末設定受信部３３において取得された目的地情報に基づいて、冷凍倉庫４ａを目的地とする車両が少なくとも１台存在するか否かが判断される（ステップＳＴ１）。冷凍倉庫４ａを目的地とする車両が存在しないと判断された場合（ステップＳＴ１のＮｏ）、第１の復帰手段４６によって、温度設定値が初期値に復帰される（ステップＳＴ６）。そして、ステップＳＴ１に戻る。一方、冷凍倉庫４ａを目的地とする車両が存在すると判断された場合（ステップＳＴ１のＹｅｓ）、判定手段４２によって、到着時間受信部３２で取得された少なくとも１台の車両の到着残り時間が、閾値時間よりも短いか否かが判定される（ステップＳＴ２）。 FIG. 7 is a flowchart showing the operation of the centralized monitoring apparatus 1 according to Embodiment 1 of the present invention. Next, the operation of the centralized monitoring apparatus 1 according to the first embodiment will be described. As shown in FIG. 7, when the control is started, first, at least one vehicle having the frozen warehouse 4a as the destination is determined based on the destination information acquired by the determination unit 41 in the terminal setting reception unit 33. It is determined whether or not it exists (step ST1). When it is determined that there is no vehicle whose destination is the frozen warehouse 4a (No in step ST1), the temperature setting value is returned to the initial value by the first return means 46 (step ST6). Then, the process returns to step ST1. On the other hand, when it is determined that there is a vehicle whose destination is the frozen warehouse 4a (Yes in step ST1), the arrival time of at least one vehicle acquired by the arrival time reception unit 32 by the determination unit 42 is: It is determined whether it is shorter than the threshold time (step ST2).
　全ての車両において、到着残り時間が閾値時間よりも長いと判定された場合（ステップＳＴ２のＮｏ）、第２の復帰手段４７によって、温度設定値が初期値に戻される（ステップＳＴ７）。そして、ステップＳＴ１に戻る。一方、少なくとも１台の車両において、到着残り時間が閾値時間よりも短いと判定された場合（ステップＳＴ２のＹｅｓ）、計測手段４３によって、判定手段４２において到着残り時間が閾値時間よりも短いと判定された車両の台数が計測される（ステップＳＴ３）。そして、比較手段４４によって、計測手段４３において計測された車両の台数が、計測手段４３において直前に計測された車両の直前台数と相違するか否かが判断される（ステップＳＴ４）。 When it is determined that the remaining arrival time is longer than the threshold time in all the vehicles (No in step ST2), the temperature setting value is returned to the initial value by the second return means 47 (step ST7). Then, the process returns to step ST1. On the other hand, when it is determined that the remaining arrival time is shorter than the threshold time in at least one vehicle (Yes in step ST2), the determination unit 42 determines that the remaining arrival time is shorter than the threshold time by the measuring unit 43. The number of used vehicles is measured (step ST3). Then, the comparison means 44 determines whether or not the number of vehicles measured by the measurement means 43 is different from the immediately preceding number of vehicles measured by the measurement means 43 (step ST4).
　車両の台数が車両の直前台数と同じと判断された場合（ステップＳＴ４のＮｏ）、維持手段４８によって、温度設定値が現状維持される（ステップＳＴ８）。そして、ステップＳＴ１に戻る。これに対し、車両の台数が車両の直前台数と相違すると判断された場合（ステップＳＴ４のＹｅｓ）、温度低下手段４５によって、計測手段４３において計測された車両の台数に基づいて、温度設定値を低下させる（ステップＳＴ５）。これにより、制御が終了し、ステップＳＴ１に戻って、制御が繰り返される。なお、この制御は、一定周期毎に行われる。 If it is determined that the number of vehicles is the same as the immediately preceding number of vehicles (No in step ST4), the temperature setting value is maintained by the maintenance unit 48 (step ST8). Then, the process returns to step ST1. On the other hand, when it is determined that the number of vehicles is different from the immediately preceding number of vehicles (Yes in step ST4), the temperature setting value is set based on the number of vehicles measured by the measuring unit 43 by the temperature lowering unit 45. Decrease (step ST5). Thereby, control is complete | finished, it returns to step ST1, and control is repeated. This control is performed at regular intervals.
　図８は、本発明の実施の形態１に係る集中監視装置１の動作を示すタイミングチャートである。次に、２台の車両Ａ，Ｂが、負荷側機器９ａが設けられた冷凍エリア１０ａのトラックヤード１１，１２，１３を目的地とする例を説明する。このとき、図６に示すように、閾値時間は１５分であり、温度シフト値は、計測された車両が０台である場合、現状維持のまま変更せず、計測された車両が１台である場合、Δｔ１、計測された車両が２台である場合、Δｔ２、計測された車両が３台である場合、Δｔ３である。なお、冷凍エリア１０ａの温度設定値の初期値は、Ｔ℃である。なお、２台の車両Ａ，Ｂは、夫々出発時間及び到着時間が相違する。 FIG. 8 is a timing chart showing the operation of the centralized monitoring apparatus 1 according to Embodiment 1 of the present invention. Next, an example will be described in which the two vehicles A and B use the truck yards 11, 12, and 13 in the refrigeration area 10a where the load-side equipment 9a is provided as destinations. At this time, as shown in FIG. 6, the threshold time is 15 minutes, and the temperature shift value is not changed while maintaining the current state when the number of measured vehicles is 0, and the measured vehicle is 1 In some cases, Δt1, Δt2 if there are two measured vehicles, and Δt3 if there are three measured vehicles. In addition, the initial value of the temperature setting value of the freezing area 10a is T ° C. The two vehicles A and B have different departure times and arrival times.
　図８に示すように、時刻ａにおいて、移動体端末２に車両Ａの目的地情報が設定され、車両Ａは、目的地に向けて出発する。図７のフローチャートにおいて、ステップＳＴ１では、冷凍倉庫４ａを目的地とする車両が１台（車両Ａ）存在するため、ステップＳＴ２に進む（ステップＳＴ１のＹｅｓ）。ステップＳＴ２では、車両Ａの到着残り時間（３０分）が閾値時間（１５分）以上である（ステップＳＴ２のＮｏ）ため、温度設定値が初期値のまま（ステップＳＴ７）、制御が終了する。このように、時刻ａにおいて、冷凍エリア１０ａの設定温度値はＴ℃のままである。 As shown in FIG. 8, at time a, the destination information of the vehicle A is set in the mobile terminal 2, and the vehicle A departs toward the destination. In the flowchart of FIG. 7, in step ST1, since there is one vehicle (vehicle A) having the frozen warehouse 4a as the destination, the process proceeds to step ST2 (Yes in step ST1). In step ST2, since the remaining arrival time (30 minutes) of the vehicle A is equal to or longer than the threshold time (15 minutes) (No in step ST2), the temperature setting value remains the initial value (step ST7), and the control ends. Thus, at the time a, the set temperature value of the freezing area 10a remains at T ° C.
　図８に示すように、時刻ｂにおいて、車両Ａの到着残り時間が１５分を切る。図７のフローチャートにおいて、ステップＳＴ１では、冷凍倉庫４ａを目的地とする車両が１台（車両Ａ）存在するため、ステップＳＴ２に進む（ステップＳＴ１のＹｅｓ）。ステップＳＴ２では、車両の到着残り時間（１５分）が閾値時間（１５分）よりも短くなるため、ステップＳＴ３に進む（ステップＳＴ２のＹｅｓ）。ステップＳＴ３では、到着残り時間が閾値時間よりも短いと判定された車両の台数が１台（車両Ａ）と計測される。ステップＳＴ４では、車両の台数（１台）が、直前に計測された車両の直前台数（０台）と相違するため、ステップＳＴ５に進む（ステップＳＴ４のＹｅｓ）。ステップＳＴ５では、計測された車両の台数が１台であるため、温度シフト値はΔｔ１であり、温度設定値はＴからΔｔ１低下される。このように、時刻ｂにおいて、冷凍エリア１０ａの温度設定値はＴ℃からＴ－Δｔ１℃に変更される。 As shown in FIG. 8, at time b, the remaining arrival time of the vehicle A is less than 15 minutes. In the flowchart of FIG. 7, in step ST1, since there is one vehicle (vehicle A) having the frozen warehouse 4a as the destination, the process proceeds to step ST2 (Yes in step ST1). In step ST2, since the remaining arrival time (15 minutes) of the vehicle is shorter than the threshold time (15 minutes), the process proceeds to step ST3 (Yes in step ST2). In step ST3, the number of vehicles determined that the remaining arrival time is shorter than the threshold time is measured as one (vehicle A). In step ST4, since the number of vehicles (one) is different from the immediately preceding number of vehicles measured (0), the process proceeds to step ST5 (Yes in step ST4). In step ST5, since the number of measured vehicles is one, the temperature shift value is Δt1, and the temperature set value is decreased from T by Δt1. Thus, at time b, the temperature setting value of the freezing area 10a is changed from T ° C. to T−Δt1 ° C.
　図８に示すように、時刻ｃにおいて、移動体端末２に車両Ｂの目的地情報が設定され、車両Ｂは、目的地に向けて出発する。図７のフローチャートにおいて、ステップＳＴ１では、冷凍倉庫４ａを目的地とする車両が２台（車両Ａ，Ｂ）存在するため、ステップＳＴ２に進む（ステップＳＴ１のＹｅｓ）。ステップＳＴ２では、車両Ｂの到着残り時間（３０分）は閾値時間（１５分）以上であるものの、車両Ａの到着残り時間が閾値時間（１５分）よりも短いため、ステップＳＴ３に進む（ステップＳＴ２のＹｅｓ）。ステップＳＴ３では、到着残り時間が閾値時間よりも短いと判定された車両の台数が１台（車両Ａ）と計測される。ステップＳＴ４では、車両の台数（１台）が、直前に計測された車両の直前台数（１台）と同じである（ステップＳＴ４のＮｏ）ため、温度設定値が維持されたまま（ステップＳＴ８）、制御が終了する。このように、時刻ｃにおいて、冷凍エリア１０ａの設定温度値はＴ－Δｔ１℃のままである。 As shown in FIG. 8, at time c, the destination information of the vehicle B is set in the mobile terminal 2, and the vehicle B departs toward the destination. In the flowchart of FIG. 7, in step ST1, since there are two vehicles (vehicles A and B) that are destined for the freezer warehouse 4a, the process proceeds to step ST2 (Yes in step ST1). In Step ST2, although the remaining arrival time (30 minutes) of the vehicle B is equal to or longer than the threshold time (15 minutes), the remaining arrival time of the vehicle A is shorter than the threshold time (15 minutes), so the process proceeds to Step ST3 (Step ST3). (Yes in ST2). In step ST3, the number of vehicles determined that the remaining arrival time is shorter than the threshold time is measured as one (vehicle A). In step ST4, the number of vehicles (one) is the same as the immediately preceding number of vehicles (one) measured (No in step ST4), so the temperature set value is maintained (step ST8). The control ends. Thus, at time c, the set temperature value of the freezing area 10a remains at T−Δt1 ° C.
　図８に示すように、時刻ｄにおいて、車両Ａは、目的地に到着し、搬入搬出作業が行われる。図７のフローチャートにおいて、ステップＳＴ１では、冷凍倉庫４ａを目的地とする車両が２台（車両Ａ，Ｂ）存在するため、ステップＳＴ２に進む（ステップＳＴ１のＹｅｓ）。ステップＳＴ２では、車両Ｂの到着残り時間は閾値時間（１５分）以上であるものの、車両Ａの到着残り時間（０分）が閾値時間（１５分）よりも短いため、ステップＳＴ３に進む（ステップＳＴ２のＹｅｓ）。ステップＳＴ３では、到着残り時間が閾値時間よりも短いと判定された車両の台数が１台（車両Ａ）と計測される。ステップＳＴ４では、車両の台数（１台）が、直前に計測された車両の直前台数（１台）と同じである（ステップＳＴ４のＮｏ）ため、温度設定値が維持されたまま（ステップＳＴ８）、制御が終了する。このように、時刻ｄにおいて、冷凍エリア１０ａの設定温度値はＴ－Δｔ１℃のままである。 As shown in FIG. 8, at time d, the vehicle A arrives at the destination and carries in / out work. In the flowchart of FIG. 7, in step ST1, since there are two vehicles (vehicles A and B) that are destined for the freezer warehouse 4a, the process proceeds to step ST2 (Yes in step ST1). In step ST2, although the remaining arrival time of the vehicle B is equal to or greater than the threshold time (15 minutes), the remaining arrival time (0 minutes) of the vehicle A is shorter than the threshold time (15 minutes), so the process proceeds to step ST3 (step ST3). (Yes in ST2). In step ST3, the number of vehicles determined that the remaining arrival time is shorter than the threshold time is measured as one (vehicle A). In step ST4, the number of vehicles (one) is the same as the immediately preceding number of vehicles (one) measured (No in step ST4), so the temperature set value is maintained (step ST8). The control ends. Thus, at the time d, the set temperature value of the freezing area 10a remains T−Δt1 ° C.
　図８に示すように、時刻ｅにおいて、車両Ｂの到着残り時間が１５分を切る。図７のフローチャートにおいて、ステップＳＴ１では、冷凍倉庫４ａを目的地とする車両が２台（車両Ａ，Ｂ）存在するため、ステップＳＴ２に進む（ステップＳＴ１のＹｅｓ）。ステップＳＴ２では、車両Ａの到着残り時間（０分）が閾値時間（１５分）よりも短く、また、車両Ｂの到着残り時間（１５分）が閾値時間（１５分）よりも短くなるため、ステップＳＴ３に進む（ステップＳＴ２のＹｅｓ）。ステップＳＴ３では、到着残り時間が閾値時間よりも短いと判定された車両の台数が２台（車両Ａ，Ｂ）と計測される。ステップＳＴ４では、車両の台数（２台）が、直前に計測された車両の直前台数（１台）と相違するため、ステップＳＴ５に進む（ステップＳＴ４のＹｅｓ）。ステップＳＴ５では、計測された車両の台数が２台であるため、温度シフト値はΔｔ２であり、温度設定値は、ＴからΔｔ２低下される。このように、時刻ｅにおいて、冷凍エリア１０ａの温度設定値はＴ－Δｔ１℃からＴ－Δｔ２℃に変更される。 As shown in FIG. 8, at time e, the remaining arrival time of the vehicle B is less than 15 minutes. In the flowchart of FIG. 7, in step ST1, since there are two vehicles (vehicles A and B) that are destined for the freezer warehouse 4a, the process proceeds to step ST2 (Yes in step ST1). In Step ST2, the remaining arrival time (0 minutes) of the vehicle A is shorter than the threshold time (15 minutes), and the remaining arrival time (15 minutes) of the vehicle B is shorter than the threshold time (15 minutes). The process proceeds to step ST3 (Yes in step ST2). In step ST3, the number of vehicles determined that the remaining arrival time is shorter than the threshold time is measured as two vehicles (vehicles A and B). In step ST4, since the number of vehicles (two) is different from the immediately preceding number of vehicles (one) measured immediately before, the process proceeds to step ST5 (Yes in step ST4). In step ST5, since the number of measured vehicles is two, the temperature shift value is Δt2, and the temperature set value is decreased from T by Δt2. Thus, at the time e, the temperature set value of the freezing area 10a is changed from T-Δt1 ° C. to T-Δt 2 ° C.
　図８に示すように、時刻ｆにおいて、車両Ａの搬入搬出作業が終了し、移動体端末２における車両Ａの目的地情報が消去される。図７のフローチャートにおいて、ステップＳＴ１では、冷凍倉庫４ａを目的地とする車両が１台（車両Ｂ）存在するため、ステップＳＴ２に進む（ステップＳＴ１のＹｅｓ）。ステップＳＴ２では、車両Ｂの到着残り時間が閾値時間（１５分）よりも短いため、ステップＳＴ３に進む（ステップＳＴ２のＹｅｓ）。ステップＳＴ３では、到着残り時間が閾値時間よりも短いと判定された車両の台数が１台（車両Ｂ）と計測される。ステップＳＴ４では、車両の台数（１台）が、直前に計測された車両の直前台数（２台）と相違するため、ステップＳＴ５に進む（ステップＳＴ４のＹｅｓ）。ステップＳＴ５では、計測された車両の台数が１台であるため、温度シフト値はΔｔ１であり、温度設定値は、ＴからΔｔ１低下される。このように、時刻ｆにおいて、冷凍エリア１０ａの温度設定値はＴ－Δｔ２℃からＴ－Δｔ１℃に変更される。 As shown in FIG. 8, at time f, the loading / unloading operation of the vehicle A is completed, and the destination information of the vehicle A in the mobile terminal 2 is erased. In the flowchart of FIG. 7, in step ST1, since there is one vehicle (vehicle B) that is destined for the freezer warehouse 4a, the process proceeds to step ST2 (Yes in step ST1). In step ST2, since the remaining arrival time of the vehicle B is shorter than the threshold time (15 minutes), the process proceeds to step ST3 (Yes in step ST2). In step ST3, the number of vehicles determined that the remaining arrival time is shorter than the threshold time is measured as one (vehicle B). In step ST4, the number of vehicles (one) is different from the immediately preceding number of vehicles (two) measured immediately before, so the process proceeds to step ST5 (Yes in step ST4). In step ST5, since the number of measured vehicles is one, the temperature shift value is Δt1, and the temperature set value is decreased from T by Δt1. Thus, at time f, the temperature setting value of the freezing area 10a is changed from T-Δt2 ° C. to T-Δt1 ° C.
　図８に示すように、時刻ｇにおいて、車両Ｂは、目的地に到着し、搬入搬出作業が行われる。図７のフローチャートにおいて、ステップＳＴ１では、冷凍倉庫４ａを目的地とする車両が１台（車両Ｂ）存在するため、ステップＳＴ２に進む（ステップＳＴ１のＹｅｓ）。ステップＳＴ２では、車両Ｂの到着残り時間（０分）が閾値時間（１５分）よりも短いため、ステップＳＴ３に進む（ステップＳＴ２のＹｅｓ）。ステップＳＴ３では、到着残り時間が閾値時間よりも短いと判定された車両の台数が１台（車両Ｂ）と計測される。ステップＳＴ４では、車両の台数（１台）が、直前に計測された車両の直前台数（１台）と同じである（ステップＳＴ４のＮｏ）ため、温度設定値が維持されたまま（ステップＳＴ８）、制御が終了する。このように、時刻ｇにおいて、冷凍エリア１０ａの設定温度値はＴ－Δｔ１℃のままである。 As shown in FIG. 8, at time g, the vehicle B arrives at the destination and carries in / out work. In the flowchart of FIG. 7, in step ST1, since there is one vehicle (vehicle B) that is destined for the freezer warehouse 4a, the process proceeds to step ST2 (Yes in step ST1). In step ST2, since the remaining arrival time (0 minutes) of the vehicle B is shorter than the threshold time (15 minutes), the process proceeds to step ST3 (Yes in step ST2). In step ST3, the number of vehicles determined that the remaining arrival time is shorter than the threshold time is measured as one (vehicle B). In step ST4, the number of vehicles (one) is the same as the immediately preceding number of vehicles (one) measured (No in step ST4), so the temperature set value is maintained (step ST8). The control ends. Thus, at time g, the set temperature value of the freezing area 10a remains T−Δt1 ° C.
　図８に示すように、時刻ｈにおいて、車両Ｂの搬入搬出作業が終了し、移動体端末２における車両Ｂの目的地情報が消去される。図７のフローチャートにおいて、ステップＳＴ１では、冷凍倉庫４ａを目的地とする車両が存在しない（ステップＳＴ１のＮｏ）ため、温度設定値が初期値に復帰され（ステップＳＴ６）、制御が終了する。 As shown in FIG. 8, at time h, the loading / unloading operation of the vehicle B is completed, and the destination information of the vehicle B in the mobile terminal 2 is deleted. In the flowchart of FIG. 7, in step ST1, since there is no vehicle having the destination of the refrigerated warehouse 4a (No in step ST1), the temperature set value is returned to the initial value (step ST6), and the control ends.
　次に、本発明の実施の形態１に係る集中監視装置１の作用について説明する。集中監視装置１は、制御部３６が、到着残り時間に基づいて、空調冷熱機器４の温度設定値を変更する。車両が冷凍倉庫４ａに到着して搬入搬出作業が行われると、扉が開かれた冷凍倉庫４ａの内部に外気が流入して温度が上昇する虞がある。また、これにより、冷凍倉庫４ａに保管された食料品等の品質が劣化する虞がある。 Next, the operation of the centralized monitoring device 1 according to Embodiment 1 of the present invention will be described. In the centralized monitoring device 1, the control unit 36 changes the temperature setting value of the air conditioning / cooling device 4 based on the remaining arrival time. When the vehicle arrives at the freezer warehouse 4a and carries in and out the work, outside air may flow into the inside of the frozen warehouse 4a with the door opened, and the temperature may rise. Moreover, there exists a possibility that quality of foodstuffs etc. which were stored by the freezer warehouse 4a may deteriorate by this.
　本実施の形態１は、制御部３６が、到着残り時間に基づいて、空調冷熱機器４の温度設定値を変更する。これにより、車両が到着する前に冷凍倉庫４ａを予め冷やし込むことができる。このため、空調冷熱機器４の管理者等が空調冷熱機器４の温度設定値を手動で変更せずとも、集中監視装置１によって、冷凍倉庫４ａの温度が上昇することを抑制することができる。また、これにより冷凍倉庫４ａに保管された食料品等の品質を保持することができる。 In the first embodiment, the control unit 36 changes the temperature setting value of the air conditioning / cooling device 4 based on the remaining arrival time. Thereby, before the vehicle arrives, the freezer warehouse 4a can be cooled in advance. For this reason, it is possible to prevent the temperature of the refrigeration warehouse 4a from rising by the centralized monitoring device 1 without the administrator of the air conditioning / cooling device 4 manually changing the temperature setting value of the air conditioning / cooling device 4. Moreover, the quality of the foodstuff etc. which were stored by this in the freezer warehouse 4a can be maintained.
　また、温度低下手段４５は、複数の車両が存在する場合、車両の台数に基づいて、温度設定値を低下させる。冷凍エリア１０ａ，１０ｂ，１０ｃ，１０ｄに複数の車両が停車して荷物の搬入搬出作業が行われる場合、冷凍倉庫４ａは、１台の車両が停車して荷物の搬入搬出作業が行われる場合よりも長時間開かれることが多い。このため、冷凍倉庫４ａ内の温度は、より上昇する。 Further, when there are a plurality of vehicles, the temperature lowering means 45 lowers the temperature set value based on the number of vehicles. When a plurality of vehicles are stopped in the refrigeration areas 10a, 10b, 10c, and 10d and the loading and unloading work is performed, the freezer warehouse 4a is more than the case where one vehicle is stopped and the loading and unloading work is performed. Are often opened for a long time. For this reason, the temperature in the freezer warehouse 4a rises more.
　本実施の形態１において、複数の車両が存在する場合、温度低下手段４５は、車両の台数に基づいて温度設定値を低下させる。そして、その温度シフト値が、車両の台数によって変更されている。更に、車両の台数が多いほど温度シフト値を大きくしているため、複数の車両が停車して搬入搬出作業が行われても、集中監視装置１によって、冷凍倉庫４ａ内の温度が上昇することを抑制することができる。また、これにより、冷凍倉庫４ａに保管された食料品等の品質を保持することができる。 In the first embodiment, when there are a plurality of vehicles, the temperature lowering means 45 lowers the temperature set value based on the number of vehicles. The temperature shift value is changed depending on the number of vehicles. Furthermore, since the temperature shift value is increased as the number of vehicles increases, the temperature in the refrigeration warehouse 4a rises by the centralized monitoring device 1 even when a plurality of vehicles stop and carry-in / out operations are performed. Can be suppressed. Thereby, the quality of foodstuffs etc. stored in the freezer warehouse 4a can be maintained.
