Description

制御装置、制御方法、プログラムおよび記録媒体Control device, control method, program, and recording medium
　本発明は、稼動することにより熱を発する設備が設置された空調対象領域（例えば、生産工場など）の空調を制御する制御装置に関するものである。 The present invention relates to a control device that controls air conditioning in an air conditioning target area (for example, a production factory) in which equipment that generates heat when operating is installed.
　製品の加工あるいは組み立て等を行う製造ラインでは、ラインを構成する加熱装置、あるいは、製造装置のモータ、コントローラ、トランス等の設備が発熱し、空気中に大量の熱を放出している。 In a production line for processing or assembling products, heating equipment constituting the line, or equipment such as motors, controllers, transformers, etc. of the production equipment generates heat and releases a large amount of heat into the air.
　他方、半導体等の製造に要するクリーンルーム、あるいは、印刷ライン、精密加工ライン等では、製品の加工精度等を安定させる目的で生産工場内の温度を略一定値に保つ空調が行われており、上記した設備からの放熱による温度上昇を抑えるために、冷却能力の高い空調装置を用いている。 On the other hand, in clean rooms required for manufacturing semiconductors, etc., printing lines, precision processing lines, etc., air conditioning is performed to keep the temperature in the production plant at a substantially constant value for the purpose of stabilizing the processing accuracy of the products, etc. In order to suppress the temperature rise due to heat radiation from the facility, an air conditioner with high cooling capacity is used.
　このため、製造ラインが停止して放熱がないような場合、能力の高い空調装置が稼動し、設定温度を超えて生産工場内を冷却してしまい（オーバーシュート）、消費電力の無駄が発生するという問題があった。 For this reason, when the production line is stopped and there is no heat dissipation, a high-capacity air conditioner is activated, and the production factory is cooled beyond the set temperature (overshoot), resulting in wasted power consumption. There was a problem.
　このような問題を解決する方法として、特許文献１には、空調対象領域内の環境データ（空気温度、ＣＯ２濃度、消費電力量）を計測し、対象領域内の装置の稼動状況や人の存在の有無により変化する環境データの増減から、空調装置の設定温度を最適値に変更する方法が提案されている。特許文献１の方法によれば、空調対象領域における温度変化を事前に予測して空調装置の稼動能力を設定できるため、冷やし過ぎ等による消費電力の無駄を抑制できる。 As a method for solving such a problem, Patent Document 1 discloses environmental data (air temperature, CO 2 concentration, power consumption) in an air-conditioning target area, and the operation status of a device in the target area and human activity. There has been proposed a method of changing the set temperature of the air conditioner to an optimum value from the increase / decrease of environmental data that changes depending on the presence or absence. According to the method of Patent Literature 1, since the temperature change in the air conditioning target region can be predicted in advance and the operating capacity of the air conditioner can be set, waste of power consumption due to excessive cooling or the like can be suppressed.
　さらに、特許文献２には、空調対象領域内の設備の消費電力と現在の温度から設定温度に達するのに必要な時間を算出し、該算出結果から最適な空調制御パターンを選択して消費電力の削減を図る方法が提案されている。 Furthermore, Patent Document 2 calculates the time required to reach the set temperature from the power consumption of the equipment in the air-conditioning target area and the current temperature, and selects the optimal air-conditioning control pattern from the calculation result to select the power consumption. There has been proposed a method for reducing this.

　しかしながら、特許文献１の方法では、設定温度の変更により空調装置の稼動能力を設定するため、一定温度への制御を必要とする生産工場での利用には不適である。また、環境データと設定温度との関係を事前に導出しておく必要があるが、対象領域の広さ、外気温度、装置、人、空調装置の配置等、多様なデータの組み合わせで変化する関係を、生産工場において正確に事前に把握することは困難である。 However, the method of Patent Document 1 sets the operating capacity of the air conditioner by changing the set temperature, and is not suitable for use in a production factory that requires control to a constant temperature. In addition, it is necessary to derive the relationship between the environmental data and the set temperature in advance, but the relationship varies depending on the combination of various data such as the size of the target area, the outside air temperature, equipment, people, and the arrangement of air conditioners. It is difficult to accurately grasp in advance in the production factory.
　また、特許文献２の方法では、一定の温度設定での制御であるため生産工場への適用は可能であるが、環境データと制御パターンの関係を事前に導出しておく必要がある。そのため、特許文献２の方法を生産工場に適用する場合にも、対象領域の広さ、外気温度、装置、人、空調装置の配置等、多様なデータの組み合わせの中で正確な関係を事前に設定することができないという課題が残る。 In addition, the method of Patent Document 2 is applicable to a production factory because it is controlled at a constant temperature setting, but it is necessary to derive the relationship between environmental data and control patterns in advance. Therefore, even when the method of Patent Document 2 is applied to a production factory, an accurate relationship among various data combinations such as the size of the target area, the outside air temperature, the device, the person, the arrangement of the air conditioner, etc. The problem remains that it cannot be set.

The purpose is to do.

　　（制御システムの全体構成）
　以下、図面を参照して本発明の一実施形態を詳細に説明する。図１は、本発明の一実施形態に係る制御システムが適用される生産工場を示す模式図である。また、図２は、当該制御システムの概略構成を示すブロック図である。 <Embodiment 1>
(Overall configuration of control system)
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing a production factory to which a control system according to an embodiment of the present invention is applied. FIG. 2 is a block diagram showing a schematic configuration of the control system.
　本実施形態の制御システム１は、一つの生産工場（空調対象領域）１０に設置された、複数の製造ライン（設備）１１～１９と、複数の空調装置２１～２８と、制御装置５０とを備える。 The control system 1 of the present embodiment includes a plurality of production lines (equipment) 11 to 19, a plurality of air conditioners 21 to 28, and a control device 50 installed in one production factory (air conditioning target area) 10. Prepare.
　製造ライン１１～１９の各々は、製品の加工あるいは組み立て等を行う各種の製造装置を含む、稼動することにより熱を発する設備である。製造ライン１１～１９の各々は、当該製造ラインで消費された電力量を計測する電力計４１～４９と接続されている。 Each of the production lines 11 to 19 is a facility that generates heat when operated, including various manufacturing apparatuses for processing or assembling products. Each of the production lines 11 to 19 is connected to wattmeters 41 to 49 that measure the amount of power consumed in the production line.
　空調装置２１・２２・２５・２６は、天井吊型の空調装置であり、空調装置２３・２４・２７・２８は、床置型の空調装置である。また、空調装置２１～２８の各々は、対応する付属の室外機３１～３８のいずれかと接続されている。空調装置と接続される室外機の数は特に限定されない。例えば、空調装置２４は２つの室外機３３・３４と接続され、空調装置２８は２つの室外機３７・３８と接続され、それ以外の空調装置は、１つの室外機と接続されている。接続される室外機の数を増やすことで空調装置の空調能力を上げることができる。さらに、複数の空調装置によって１つの室外機を共用してもよい。例えば、空調装置２１および空調装置２２は室外機３１を共用しており、空調装置２５および空調装置２６は室外機３５を共用している。 The air conditioners 21, 22, 25, and 26 are ceiling-suspended air conditioners, and the air conditioners 23, 24, 27, and 28 are floor-type air conditioners. Each of the air conditioners 21 to 28 is connected to one of the corresponding attached outdoor units 31 to 38. The number of outdoor units connected to the air conditioner is not particularly limited. For example, the air conditioner 24 is connected to two outdoor units 33 and 34, the air conditioner 28 is connected to two outdoor units 37 and 38, and the other air conditioners are connected to one outdoor unit. The air conditioning capability of the air conditioner can be increased by increasing the number of connected outdoor units. Further, one outdoor unit may be shared by a plurality of air conditioners. For example, the air conditioner 21 and the air conditioner 22 share the outdoor unit 31, and the air conditioner 25 and the air conditioner 26 share the outdoor unit 35.
　空調装置２１～２８は、運転している際、周囲の温度を測定し、その測定温度が予め定められた設定温度になるように制御される。例えば冷房運転時には、空調装置２１～２８は、測定温度が設定温度よりも高い場合に室内を降温させる動作（降温動作）を行い、測定温度が設定温度よりも低い場合に一時停止する。また暖房運転時には、空調装置２１～２８は、測定温度が設定温度よりも高い場合に一時停止し、測定温度が設定温度よりも低い場合に室内を昇温させる動作（昇温動作）を行う。 The air conditioners 21 to 28 measure the ambient temperature during operation, and are controlled so that the measured temperature becomes a preset temperature. For example, during the cooling operation, the air conditioners 21 to 28 perform an operation of lowering the room temperature (temperature lowering operation) when the measured temperature is higher than the set temperature, and temporarily stop when the measured temperature is lower than the set temperature. During the heating operation, the air conditioners 21 to 28 temporarily stop when the measured temperature is higher than the set temperature, and perform an operation (temperature increase operation) for raising the temperature of the room when the measured temperature is lower than the set temperature.
　制御装置５０は、複数の空調装置２１～２８の動作を制御するものである。制御装置５０は、複数の空調装置２１～２８を、製造ライン１１～１９の稼動と関係なく運転させる第１グループと、製造ラインの稼動に応じて運転制御される第２グループとに分け、各グループに応じた制御を行う。 The control device 50 controls the operation of the plurality of air conditioners 21 to 28. The control device 50 divides the plurality of air conditioners 21 to 28 into a first group that operates regardless of the operation of the production lines 11 to 19 and a second group that is operated and controlled according to the operation of the production line. Control according to the group.
　　（制御装置の構成）
　次に制御装置５０の内部構成について説明する。図２に示されるように、制御装置５０は、グループ情報記憶部５１と、空調－ライン対応テーブル記憶部（設備識別情報記憶部）５２と、制御部５３と、入力部５４とを備えている。 (Configuration of control device)
Next, the internal configuration of the control device 50 will be described. As shown in FIG. 2, the control device 50 includes a group information storage unit 51, an air conditioning-line correspondence table storage unit (facility identification information storage unit) 52, a control unit 53, and an input unit 54. .
　グループ情報記憶部５１は、製造ライン１１～１９の稼動に関係なく運転させる第１グループに属する空調装置と、製造ラインの稼動に応じて運転制御される第２グループに属する空調装置とを示すグループ情報を記憶する。図３は、グループ情報記憶部５１が記憶するグループ情報の一例を示す図である。図３に示されるように、ここでは、空調装置２１・２５が第１グループに属しており、他の空調装置２２～２４・２６～２８が第２グループに属している。 The group information storage unit 51 is a group indicating the air conditioners belonging to the first group that are operated regardless of the operation of the production lines 11 to 19 and the air conditioners belonging to the second group that are operation-controlled according to the operation of the production lines. Store information. FIG. 3 is a diagram illustrating an example of group information stored in the group information storage unit 51. As shown in FIG. 3, here, the air conditioners 21 and 25 belong to the first group, and the other air conditioners 22 to 24 and 26 to 28 belong to the second group.
　グループ情報記憶部５１は、入力部５４へのユーザ入力に応じたグループ情報を記憶する。そのため、ある空調装置が属するグループを変更する場合、ユーザはその旨を入力部５４に入力し、グループ情報記憶部５１は入力に従ってグループ情報を更新する。 The group information storage unit 51 stores group information according to user input to the input unit 54. Therefore, when changing the group to which a certain air conditioner belongs, the user inputs the fact to the input unit 54, and the group information storage unit 51 updates the group information according to the input.
　空調－ライン対応テーブル記憶部５２は、第２グループに属する空調装置２２～２４・２６～２８の各々について、当該空調装置を示す空調装置識別情報と、当該空調装置の最も近くに設置された製造ラインを識別する第１ライン識別情報（第１設備識別情報）と、当該製造ラインの停止を判断するための第１閾値とを対応付けた空調－ライン対応テーブルを記憶する。図４は、空調－ライン対応テーブル記憶部５２が記憶する空調－ライン対応テーブルの一例を示す図である。 The air conditioner-line correspondence table storage unit 52 includes, for each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group, the air conditioner identification information indicating the air conditioner and the manufacturing installed closest to the air conditioner. An air conditioning-line correspondence table in which first line identification information (first facility identification information) for identifying a line is associated with a first threshold value for determining the stop of the production line is stored. FIG. 4 is a diagram showing an example of the air conditioning-line correspondence table stored in the air conditioning-line correspondence table storage unit 52. As shown in FIG.
　なお、第１閾値は、対応する製造ラインが稼動しているときの所定期間（例えば１０分間）における消費電力量よりも小さく、当該製造ラインが停止しているときの所定期間における消費電力量よりもわずかに大きい値が設定されている。 The first threshold value is smaller than the power consumption during a predetermined period (for example, 10 minutes) when the corresponding production line is operating, and is smaller than the power consumption during the predetermined period when the production line is stopped. A slightly larger value is set.
　空調－ライン対応テーブル記憶部５２は、入力部５４へのユーザ入力に応じた空調－ライン対応テーブルを記憶する。そのため、生産工場１０内のレイアウトを変更した場合、ユーザは新たなレイアウトに応じた第１ライン識別情報の変更指示を入力部５４に入力し、空調－ライン対応テーブル記憶部５２は入力に従って空調－ライン対応テーブルを更新する。 The air conditioning / line correspondence table storage unit 52 stores an air conditioning / line correspondence table corresponding to a user input to the input unit 54. Therefore, when the layout in the production factory 10 is changed, the user inputs an instruction to change the first line identification information corresponding to the new layout to the input unit 54, and the air conditioning-line correspondence table storage unit 52 performs the air conditioning- Update the line correspondence table.
　制御部５３は、グループに応じて各空調装置２１～２８を制御するものである。制御部５３は、第１グループに属する空調装置２１・２５に対して、従来の設定温度に応じた動作を行うように制御する。すなわち、第１グループに属する空調装置２１・２５は、測定温度が設定温度になるように動作する。 The control unit 53 controls the air conditioners 21 to 28 according to the group. The control unit 53 controls the air conditioners 21 and 25 belonging to the first group so as to perform an operation according to a conventional set temperature. That is, the air conditioners 21 and 25 belonging to the first group operate so that the measured temperature becomes the set temperature.
　また、制御部５３は、第２グループに属する空調装置２２～２４・２６～２８の各々に対して、当該空調装置を示す空調装置識別情報に対応する第１ライン識別情報および第１閾値を空調－ライン対応テーブルから読み出す。制御部５３は、読み出した第１ライン識別情報で示される製造ラインに接続された電力計の計測データに基づいて、所定期間（例えば、現時刻から過去１０分遡った期間）の消費電力量（以下、第１消費電力量という）を算出し、第１閾値と比較する。 In addition, the control unit 53 air-conditions the first line identification information and the first threshold value corresponding to the air conditioner identification information indicating the air conditioner for each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group. -Read from the line correspondence table. Based on the measurement data of the wattmeter connected to the production line indicated by the read first line identification information, the control unit 53 uses the power consumption amount for a predetermined period (for example, a period 10 minutes past the current time) ( Hereinafter, the first power consumption amount) is calculated and compared with the first threshold value.
　第１閾値は、上述したように、製造ラインが運転（稼動）しているときの所定期間（例えば１０分間）における消費電力量よりも小さく、当該製造ラインが運転停止しているときの所定期間における消費電力量よりもわずかに大きい値が設定されている。そのため、算出した第１消費電力量が第１閾値よりも低い場合、制御部５３は、第１ライン識別情報で示される製造ラインが停止しているものと判断することができる。また、算出した第１消費電力量が第１閾値以上である場合、制御部５３は、第１ライン識別情報で示される製造ラインが稼動しているものと判断することができる。 As described above, the first threshold value is smaller than the power consumption amount in a predetermined period (for example, 10 minutes) when the production line is operating (operating), and the predetermined period when the manufacturing line is stopped. A value slightly larger than the amount of power consumption in is set. Therefore, when the calculated first power consumption amount is lower than the first threshold, the control unit 53 can determine that the production line indicated by the first line identification information is stopped. When the calculated first power consumption is equal to or greater than the first threshold, the control unit 53 can determine that the production line indicated by the first line identification information is operating.
　そして、制御部５３は、製造ラインが停止していると判断した場合、冷房運転時には空調装置の運転を停止し、暖房運転時には空調装置を運転させる。一方、制御部５３は、製造ラインが稼動していると判断した場合、冷房運転時には空調装置を運転させ、暖房運転時には空調装置を運転停止させる。制御部５３により運転するように制御された空調装置は、測定温度が設定温度になるように動作制御される。 When the control unit 53 determines that the production line is stopped, the control unit 53 stops the operation of the air conditioner during the cooling operation, and operates the air conditioner during the heating operation. On the other hand, when it is determined that the production line is operating, the control unit 53 operates the air conditioner during the cooling operation and stops the air conditioner during the heating operation. The air conditioner controlled to operate by the control unit 53 is controlled so that the measured temperature becomes the set temperature.
　このように制御部５３は、複数の空調装置２１～２８を第１グループと第２グループとに分け、第１グループに属する空調装置２１・２５については、製造ライン１１～１９の稼動状態にかかわらず運転させ、前記第２グループに属する空調装置２２～２４・２６～２８については、製造ライン１１～１９の稼動状態に応じて運転を制御する。そのため、製造ライン１１～１９の放熱量に応じて第２グループの空調装置２２～２４・２６～２８を運転させることができる。その結果、第２グループの空調装置２２～２４・２６～２８については、製造ライン１１～１９からの放熱に応じて無駄な運転を避けることができ、省電力化を図ることができる。例えば、製造ライン１１～１９が停止し放熱がないときには、第２グループの空調装置２２～２４・２６～２８の冷房運転を停止することで、無駄な運転を避けることができる。また、第１グループに属する空調装置２１・２５は、製造ライン１１～１９の稼動状態に関係なく運転される。そのため、例えば冷房運転時には、設備が稼動していない場合でも、第１グループに属する空調装置により、生産工場内の温度が設定温度に保たれる。 As described above, the control unit 53 divides the plurality of air conditioners 21 to 28 into the first group and the second group, and the air conditioners 21 and 25 belonging to the first group depend on the operating state of the production lines 11 to 19. The air conditioners 22 to 24 and 26 to 28 belonging to the second group are controlled in accordance with the operating states of the production lines 11 to 19. Therefore, the second group of air conditioners 22 to 24 and 26 to 28 can be operated according to the heat radiation amount of the production lines 11 to 19. As a result, the second group of air conditioners 22 to 24 and 26 to 28 can avoid unnecessary operation in accordance with the heat radiation from the production lines 11 to 19 and can save power. For example, when the production lines 11 to 19 are stopped and there is no heat radiation, useless operation can be avoided by stopping the cooling operation of the second group of air conditioners 22 to 24 and 26 to 28. Further, the air conditioners 21 and 25 belonging to the first group are operated regardless of the operating state of the production lines 11 to 19. Therefore, for example, at the time of cooling operation, the temperature in the production factory is maintained at the set temperature by the air conditioner belonging to the first group even when the equipment is not operating.
　このように、複数の空調装置２１～２８を、第１グループと第２グループとに分けるという簡単な設定により、無駄な電力を消費することなく、生産工場の温度を一定に保つことができる。すなわち、特許文献１・２のような生産工場の条件によって変化する環境データを詳細に取得する必要がない。また、空調対象領域内の設備や空調装置のレイアウトが変更されたとしても、特許文献１・２のような環境データを再度取得する必要がない。 Thus, by simply setting the plurality of air conditioners 21 to 28 into the first group and the second group, the temperature of the production plant can be kept constant without consuming unnecessary power. That is, it is not necessary to acquire in detail the environmental data that changes according to the conditions of the production factory as in Patent Documents 1 and 2. Further, even if the layout of the equipment and air conditioners in the air conditioning target area is changed, it is not necessary to acquire environmental data as in Patent Documents 1 and 2 again.
　　（空調装置の制御処理の流れ（冷房運転時））
　次に本実施形態における空調装置２１～２８の制御処理の一例について、図５を参照しながら説明する。図５は、本実施形態における空調装置２１～２８の制御処理の流れを示すフローチャートである。なお、図５は、夏季において空調装置２１～２８を冷房運転させる場合の例である。 (Flow of control processing of air conditioner (during cooling operation))
Next, an example of control processing of the air conditioners 21 to 28 in the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing a flow of control processing of the air conditioners 21 to 28 in the present embodiment. FIG. 5 shows an example in which the air conditioners 21 to 28 are in a cooling operation in summer.
　まず、制御部５３は、制御対象となる空調装置２１～２８を一つ選択する。そして、制御部５３は、制御対象の空調装置が第２グループに属するか否かを判断する（Ｓ１）。制御部５３は、グループ情報記憶部５１が記憶するグループ情報を参照することでＳ１の判断を行う。 First, the control unit 53 selects one of the air conditioners 21 to 28 to be controlled. Then, the control unit 53 determines whether or not the air conditioner to be controlled belongs to the second group (S1). The control unit 53 determines S1 by referring to the group information stored in the group information storage unit 51.
　制御対象の空調装置が第２グループに属さない場合（Ｓ１でＮｏ）、つまり、制御対象の空調装置が第１グループに属する場合、制御部５３は、制御対象の空調装置について、当該空調装置による測定温度と設定温度とを比較する（Ｓ２）。測定温度が設定温度よりも高い場合（Ｓ２でＹｅｓ）、制御部５３は、制御対象の空調装置について降温動作を行わせる（Ｓ３）。一方、測定温度が設定温度以下である場合（Ｓ２でＮｏ）、制御部５３は、制御対象の空調装置を一時停止させる（Ｓ４）。 When the air conditioner to be controlled does not belong to the second group (No in S1), that is, when the air conditioner to be controlled belongs to the first group, the control unit 53 uses the air conditioner to control the air conditioner to be controlled. The measured temperature is compared with the set temperature (S2). When the measured temperature is higher than the set temperature (Yes in S2), the control unit 53 causes the air-conditioning apparatus to be controlled to perform a temperature lowering operation (S3). On the other hand, when the measured temperature is equal to or lower than the set temperature (No in S2), the control unit 53 temporarily stops the air conditioner to be controlled (S4).
　また、制御対象の空調装置が第２グループに属する場合（Ｓ１でＹｅｓ）、制御部５３は、制御対象の空調装置を示す空調装置識別情報に対応する第１ライン識別情報および第１閾値を空調－ライン対応テーブルから読み出す（Ｓ５）。これにより、制御部５３は、制御対象の空調装置に最も近い製造ラインを特定することができる。 When the air conditioner to be controlled belongs to the second group (Yes in S1), the control unit 53 air-conditions the first line identification information and the first threshold corresponding to the air conditioner identification information indicating the air conditioner to be controlled. Read from the line correspondence table (S5). Thereby, the control part 53 can pinpoint the manufacturing line nearest to the air conditioner of control object.
　次に、制御部５３は、Ｓ５で読み出した第１ライン識別情報で示される製造ラインに接続された電力計の計測データから、所定期間（例えば、現時刻から過去１０分遡った期間）の第１消費電力量を算出する。制御部５３は、各製造ライン１１～１９に対応する電力計４１～４９の過去の計測データを蓄積しておくことで、第１消費電力量を算出することができる。そして、制御部５３は、算出した第１消費電力量がＳ５で読み出した第１閾値以上であるか否かを判断する（Ｓ６）。 Next, the control unit 53 determines the first period of a predetermined period (for example, a period of 10 minutes past the current time) from the measurement data of the wattmeter connected to the production line indicated by the first line identification information read in S5. One power consumption is calculated. The control unit 53 can calculate the first power consumption amount by accumulating the past measurement data of the wattmeters 41 to 49 corresponding to the respective production lines 11 to 19. And the control part 53 judges whether the calculated 1st power consumption is more than the 1st threshold value read by S5 (S6).
　第１消費電力量が第１閾値以上である場合（Ｓ６でＹｅｓ）、制御部５３は、製造ラインが稼動していると判断し、制御対象の空調装置についてＳ２の処理に移行する。すなわち、制御部５３は、制御対象の空調装置について、空調能力を下げることなく、設定温度に応じた通常の運転をさせる。 When the first power consumption is equal to or greater than the first threshold (Yes in S6), the control unit 53 determines that the production line is operating, and shifts to the process of S2 for the air conditioner to be controlled. That is, the control unit 53 causes the controlled air conditioner to perform a normal operation according to the set temperature without reducing the air conditioning capacity.
　一方、第１消費電力量が第１閾値未満である場合（Ｓ６でＮｏ）、制御部５３は、製造ラインが停止していると判断し、制御対象の空調装置の運転を停止する（Ｓ７）。例えば、第１ライン識別情報で示される製造ライン１２の第１消費電力量が第１閾値（０．５ｋＷ、図４参照）よりも低いとき、製造ライン１２の近傍に床置きされた、制御対象である空調装置２３の運転を停止させる。また、第１ライン識別情報で示される製造ライン１５の第１消費電力量が第１閾値（０．３ｋＷ、図４参照）よりも低いとき、製造ライン１５の直上に設置された、制御対象である空調装置２６の運転を停止させる。その後、再度Ｓ１に戻り、Ｓ１～Ｓ７の処理を繰り返す。 On the other hand, when the first power consumption is less than the first threshold (No in S6), the control unit 53 determines that the production line is stopped, and stops the operation of the controlled air conditioner (S7). . For example, when the first power consumption of the production line 12 indicated by the first line identification information is lower than the first threshold (0.5 kW, see FIG. 4), the control target placed on the floor in the vicinity of the production line 12 The operation of the air conditioner 23 is stopped. Further, when the first power consumption of the production line 15 indicated by the first line identification information is lower than the first threshold (0.3 kW, see FIG. 4), the control target installed immediately above the production line 15 The operation of an air conditioner 26 is stopped. Thereafter, the process returns to S1 again, and the processes of S1 to S7 are repeated.
　制御部５３は、全ての空調装置２１～２８について、Ｓ１からＳ７の処理を実行する。 The control unit 53 executes the processing from S1 to S7 for all the air conditioners 21 to 28.
　このように、制御部５３は、第２グループに属する空調装置の各々について、（１）当該空調装置に対応する第１ライン識別情報で示される製造ライン（設備）の第１消費電力量が所定の第１閾値未満である場合に、当該空調装置を停止させ、（２）第１消費電力量が第１閾値以上である場合に、空調能力を低下させることなく当該空調装置を運転させる。 As described above, the control unit 53 determines, for each of the air conditioners belonging to the second group, (1) the first power consumption amount of the production line (facility) indicated by the first line identification information corresponding to the air conditioner is predetermined. If the air conditioner is less than the first threshold value, the air conditioner is stopped. (2) If the first power consumption is equal to or greater than the first threshold value, the air conditioner is operated without reducing the air conditioning capacity.
　これにより、第２グループに属する空調装置２２～２４・２６～２８は、最も近くに設置された製造ラインが稼動しているときに限り、測定温度が設定温度になるように冷房運転され、最も近くに設置された製造ラインが停止しているときには停止される。その結果、製造ラインが停止しており、当該製造ラインからの放熱がない場合において、近傍の空調装置を無駄に運転させることがなくなり、過冷却を防止できる。また、製造ラインが稼動しているときには、近傍の空調装置を運転させることができ、製造ラインからの放熱による温度上昇を効果的に防ぐことができる。 As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group are cooled so that the measured temperature becomes the set temperature only when the nearest production line is in operation. It is stopped when the production line installed nearby is stopped. As a result, when the production line is stopped and there is no heat radiation from the production line, the nearby air conditioner is not operated wastefully, and overcooling can be prevented. Further, when the production line is in operation, a nearby air conditioner can be operated, and a temperature increase due to heat radiation from the production line can be effectively prevented.
　　（空調装置の制御処理の流れ（暖房運転時））
　次に本実施形態における空調装置２１～２８の制御処理の他例について、図６を参照しながら説明する。なお、図６は、冬季において空調装置２１～２８を暖房運転させる場合の例である。 (Flow of control processing of air conditioner (during heating operation))
Next, another example of the control processing of the air conditioners 21 to 28 in the present embodiment will be described with reference to FIG. FIG. 6 shows an example in which the air conditioners 21 to 28 are operated for heating in winter.
　まず、制御部５３は、図５と同様のＳ１の処理を行う。制御対象の空調装置が第２グループに属さない場合（Ｓ１でＮｏ）、つまり、制御対象の空調装置が第１グループに属する場合、制御部５３は、制御対象の空調装置について、当該空調装置による測定温度と設定温度とを比較する（Ｓ８）。測定温度が設定温度よりも低い場合（Ｓ８でＹｅｓ）、制御部５３は、制御対象の空調装置について昇温動作を行わせる（Ｓ９）。一方、測定温度が設定温度以上である場合（Ｓ８でＮｏ）、制御部５３は、制御対象の空調装置を一時停止させる（Ｓ４）。 First, the control unit 53 performs the same processing of S1 as in FIG. When the air conditioner to be controlled does not belong to the second group (No in S1), that is, when the air conditioner to be controlled belongs to the first group, the control unit 53 uses the air conditioner to control the air conditioner to be controlled. The measured temperature is compared with the set temperature (S8). When the measured temperature is lower than the set temperature (Yes in S8), the control unit 53 causes the air conditioning device to be controlled to perform a temperature raising operation (S9). On the other hand, when the measured temperature is equal to or higher than the set temperature (No in S8), the control unit 53 temporarily stops the air conditioner to be controlled (S4).
　また、制御対象の空調装置が第２グループに属する場合（Ｓ１でＹｅｓ）、制御部５３は、実施形態１と同様に、Ｓ５およびＳ６の処理を行う。すなわち、制御部５３は、制御対象の空調装置に最も近い製造ラインにおける所定期間の第１消費電力量を算出し、第１閾値と比較する。 If the air conditioner to be controlled belongs to the second group (Yes in S1), the control unit 53 performs the processes of S5 and S6 as in the first embodiment. That is, the control unit 53 calculates the first power consumption amount for a predetermined period in the production line closest to the air conditioner to be controlled, and compares it with the first threshold value.
　第１消費電力量が第１閾値未満である場合（Ｓ６でＮｏ）、制御部５３は、製造ラインが停止していると判断し、制御対象の空調装置についてＳ８の処理に移行する。すなわち、制御対象の空調装置について、空調能力を下げることなく、設定温度に応じた通常の運転をさせる。 When the first power consumption is less than the first threshold (No in S6), the control unit 53 determines that the production line is stopped, and shifts to the process of S8 for the air conditioner to be controlled. That is, the air conditioner to be controlled is caused to perform a normal operation according to the set temperature without lowering the air conditioning capacity.
　一方、第１消費電力量が第１閾値以上である場合（Ｓ６でＹｅｓ）、制御部５３は、製造ラインが稼動していると判断し、制御対象の空調装置の運転を停止する（Ｓ７）。その後、再度Ｓ１に戻り、Ｓ１～Ｓ９（Ｓ２、Ｓ３を除く）の処理を繰り返す。 On the other hand, when the first power consumption is equal to or greater than the first threshold (Yes in S6), the control unit 53 determines that the production line is operating and stops the operation of the air conditioner to be controlled (S7). . Thereafter, the process returns to S1 again, and the processes of S1 to S9 (excluding S2 and S3) are repeated.
　制御部５３は、全ての空調装置について、図６に示すＳ１からＳ９（Ｓ２、Ｓ３を除く）の処理を実行する。 The control part 53 performs the process of S1 to S9 (except S2 and S3) shown in FIG. 6 about all the air conditioners.
　このように、制御部５３は、第２グループに属する空調装置の各々について、（１）当該空調装置に対応する第１ライン識別情報で示される製造ライン（設備）の第１消費電力量が所定の第１閾値以上である場合に、当該空調装置を停止させ、（２）第１消費電力量が第１閾値未満である場合に、空調能力を低下させることなく当該空調装置を運転させる。 As described above, the control unit 53 determines, for each of the air conditioners belonging to the second group, (1) the first power consumption amount of the production line (facility) indicated by the first line identification information corresponding to the air conditioner is predetermined. The air conditioner is stopped when it is equal to or greater than the first threshold, and (2) when the first power consumption is less than the first threshold, the air conditioner is operated without reducing the air conditioning capacity.
　これにより、第２グループに属する空調装置２２～２４・２６～２８は、最も近くに設置された製造ラインが停止しているときに限り、測定温度が設定温度になるように暖房運転され、最も近くに設置された製造ラインが稼動しているときには停止される。その結果、製造ラインが稼動しており、当該製造ラインからの放熱がある場合において、近傍の空調装置を無駄に暖房運転させることがなくなる。また、製造ラインが停止しているときには、近傍の空調装置を暖房運転させることができ、製造ラインからの放熱がないことによる温度低下を効果的に防ぐことができる。 As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group are heated so that the measured temperature becomes the set temperature only when the nearest production line is stopped. It is stopped when a nearby production line is in operation. As a result, when the production line is in operation and there is heat radiation from the production line, a nearby air conditioner is not heated unnecessarily. In addition, when the production line is stopped, a nearby air conditioner can be operated for heating, and a temperature decrease due to the absence of heat radiation from the production line can be effectively prevented.
　なお、上記の説明では、空調－ライン対応テーブル記憶部５２は、空調装置に最も近い製造ラインを示す情報を第１ライン識別情報として記憶するものとした。しかしながら、これに限定されず、空調－ライン対応テーブル記憶部５２は、空調装置に近傍の製造ラインを示す情報を第１ライン識別情報として記憶してもよい。例えば、最も近い製造ラインが稼動するときの放熱量に比べて、２番目に近い製造ラインが稼動するときの放熱量が格段に大きい場合には、当該２番目に近い製造ラインを示す情報を第１ライン識別情報として設定してもよい。これにより、近傍に設置され、かつ、放熱量の大きい製造ラインの稼動に応じて空調装置の運転を制御することができる。 In the above description, the air conditioning / line correspondence table storage unit 52 stores information indicating the production line closest to the air conditioning apparatus as the first line identification information. However, the present invention is not limited to this, and the air conditioning-line correspondence table storage unit 52 may store information indicating the nearby manufacturing lines in the air conditioning apparatus as the first line identification information. For example, when the heat radiation amount when the second closest production line is operated is much larger than the heat radiation amount when the nearest production line is operated, information indicating the second closest production line is displayed. You may set as 1 line identification information. Thereby, it is possible to control the operation of the air conditioner according to the operation of a production line installed in the vicinity and having a large amount of heat radiation.
　＜実施形態２＞
　本発明の他の実施形態について説明する。なお、説明の便宜上、実施形態１と同様の機能を有する部材には実施形態１と同じ符号を付し、その説明を省略する。 <Embodiment 2>
Another embodiment of the present invention will be described. For convenience of explanation, members having the same functions as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and description thereof is omitted.
　上記の実施形態１では、何れかの空調装置が故障で停止しているときに、その空調装置に隣接する空調装置をＳ７の処理で停止させると、空調能力が極端に低下する可能性がある。また、隣接する製造ラインが同時に停止した場合も、隣接する空調装置が同時に停止する。そのため、生産工場のレイアウトによっては空調能力が極端に低下する可能性がある。本実施形態は、このような問題をも解消できる形態である。 In the first embodiment, when any air conditioner is stopped due to a failure, if the air conditioner adjacent to the air conditioner is stopped in the process of S7, the air conditioning capability may be extremely reduced. . Moreover, when an adjacent production line stops simultaneously, the adjacent air conditioner also stops simultaneously. Therefore, depending on the layout of the production factory, the air conditioning capability may be extremely reduced. In the present embodiment, such a problem can be solved.
　図７は、本実施形態２の制御システム１０１を示す図である。図７に示されるように、各空調装置２１～２８は、当該空調装置で消費された電力量を計測する電力計６１～６８と接続されている点で、実施形態１と異なる。また、本実施形態の制御装置１５０は、制御部５３の代わりに制御部１５３を備え、さらに周辺装置情報記憶部１５５を備える点で実施形態１の制御装置５０と異なる。 FIG. 7 is a diagram illustrating the control system 101 according to the second embodiment. As shown in FIG. 7, each air conditioner 21 to 28 is different from the first embodiment in that it is connected to wattmeters 61 to 68 that measure the amount of power consumed by the air conditioner. The control device 150 of the present embodiment is different from the control device 50 of the first embodiment in that the control device 150 includes a control unit 153 instead of the control unit 53 and further includes a peripheral device information storage unit 155.
　周辺装置情報記憶部１５５は、第２グループに属する空調装置２２～２４・２６～２８の各々について、当該空調装置を識別する空調装置識別情報と、当該空調装置の周辺の位置する空調装置（周辺空調装置）を識別する周辺装置識別情報（装置識別情報）と、当該周辺空調装置の停止を判断するための第２閾値とを対応付けた周辺装置情報を記憶するものである。図８は、周辺装置情報の一例を示す図である。 The peripheral device information storage unit 155 includes, for each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group, air conditioner identification information for identifying the air conditioner, and an air conditioner (peripheral position) around the air conditioner. Peripheral device information in which peripheral device identification information (device identification information) for identifying the air conditioner) is associated with a second threshold value for determining the stop of the peripheral air conditioner is stored. FIG. 8 is a diagram illustrating an example of peripheral device information.
　なお、第２閾値は、対応する空調装置が運転しているときの所定期間（例えば１０分間）における消費電力量よりも小さく、空調装置が停止しているときの所定期間における消費電力量よりもわずかに大きい値が設定されている。 The second threshold is smaller than the power consumption during a predetermined period (for example, 10 minutes) when the corresponding air conditioner is operating, and is smaller than the power consumption during the predetermined period when the air conditioner is stopped. A slightly larger value is set.
　周辺装置情報記憶部１５５は、入力部５４へのユーザ入力に応じた周辺装置情報を記憶する。そのため、生産工場内のレイアウトを変更した場合、ユーザは新たなレイアウトに応じた周辺装置情報の変更指示を入力部５４に入力し、周辺装置情報記憶部１５５は入力に従って周辺装置情報を更新する。 Peripheral device information storage unit 155 stores peripheral device information according to user input to input unit 54. Therefore, when the layout in the production factory is changed, the user inputs an instruction to change peripheral device information according to the new layout to the input unit 54, and the peripheral device information storage unit 155 updates the peripheral device information according to the input.
　制御部１５３は、実施形態１の制御部５３と同様に、グループに応じて各空調装置２１～２８を制御する。ただし、第２グループに属する空調装置２２～２４・２６～２８に対する制御処理が実施形態１と異なる。 The control unit 153 controls each of the air conditioners 21 to 28 according to the group, like the control unit 53 of the first embodiment. However, the control processing for the air conditioners 22 to 24 and 26 to 28 belonging to the second group is different from that of the first embodiment.
　制御部１５３は、第２グループに属する空調装置２２～２４・２６～２８の各々に対して、当該空調装置を示す空調装置識別情報に対応する第１ライン識別情報および第１閾値を空調－ライン対応テーブルから読み出す。制御部１５３は、読み出した第１ライン識別情報で示される製造ラインに接続された電力計の計測データに基づいて、所定期間（例えば、現時刻から過去１０分遡った期間）の第１消費電力量を算出し、第１閾値と比較する。そして、制御部は、実施形態１と同様に、算出した第１消費電力量が第１閾値よりも低い場合に製造ラインが停止しているものと判断し、算出した第１消費電力量が第１閾値以上である場合に製造ラインが稼動しているものと判断する。制御部１５３は、暖房運転時に製造ラインが停止していると判断した場合、空調装置を運転させ、冷房運転時に製造ラインが稼動していると判断した場合、空調装置を運転させる。 For each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group, the control unit 153 sets the first line identification information and the first threshold corresponding to the air conditioner identification information indicating the air conditioner to the air conditioning line. Read from the correspondence table. Based on the measurement data of the wattmeter connected to the production line indicated by the read first line identification information, the control unit 153 performs the first power consumption for a predetermined period (for example, a period that goes back 10 minutes from the current time). An amount is calculated and compared to a first threshold. Then, similarly to the first embodiment, the control unit determines that the production line is stopped when the calculated first power consumption is lower than the first threshold, and the calculated first power consumption is the first power consumption. If it is equal to or greater than one threshold, it is determined that the production line is operating. The control unit 153 operates the air conditioner when it is determined that the production line is stopped during the heating operation, and operates the air conditioner when it is determined that the production line is operating during the cooling operation.
　一方、制御部１５３は、冷房運転時に製造ラインが停止していると判断した場合、もしくは、暖房運転時に製造ラインが稼動していると判断した場合、以下のような処理を行う。すなわち、制御部１５３は、制御対象の空調装置を示す空調装置識別情報に対応する周辺装置識別情報および第２閾値を周辺装置情報から読み出す。そして、制御部１５３は、読み出した周辺装置識別情報で示される空調装置の電力計の計測データに基づいて、所定期間（例えば、現時刻から過去１０分遡った期間）の消費電力量（以下、第２消費電力量という）を算出し、第２閾値と比較する。 On the other hand, when the control unit 153 determines that the production line is stopped during the cooling operation or when it is determined that the production line is operating during the heating operation, the control unit 153 performs the following processing. That is, the control unit 153 reads the peripheral device identification information and the second threshold corresponding to the air conditioner identification information indicating the air conditioner to be controlled from the peripheral device information. And the control part 153 is based on the measurement data of the wattmeter of the air conditioner shown by the read peripheral device identification information, and is the power consumption amount (henceforth, the following 10 minutes from the present time) 2nd power consumption amount) is calculated and compared with the second threshold value.
　上述したように、第２閾値は、空調装置が運転しているときの所定期間における消費電力量よりも小さく、空調装置が停止しているときの所定期間における消費電力量よりもわずかに大きい値が設定されている。そのため、第２消費電力量が第２閾値よりも低い場合、制御部１５３は、空調装置が停止しているものと判断することができる。 As described above, the second threshold value is a value that is smaller than the power consumption amount during the predetermined period when the air conditioner is operating and slightly larger than the power consumption amount during the predetermined period when the air conditioner is stopped. Is set. Therefore, when the second power consumption amount is lower than the second threshold, the control unit 153 can determine that the air conditioner is stopped.
　第２消費電力量が第２閾値以下である場合、制御部１５３は、周辺の空調装置が運転していると判断し、制御対象の空調装置を停止させる。一方、第２消費電力量が第２閾値未満である場合、制御部１５３は、周辺の空調装置が停止していると判断し、制御対象の空調装置を停止させずに運転させる。なお、制御部１５３により運転するように制御された空調装置は、測定温度が設定温度になるように動作制御される。 If the second power consumption is less than or equal to the second threshold, the control unit 153 determines that the surrounding air conditioner is operating, and stops the air conditioner to be controlled. On the other hand, when the second power consumption amount is less than the second threshold, the control unit 153 determines that the surrounding air conditioner is stopped, and operates the controlled air conditioner without stopping. The air conditioner controlled to operate by the control unit 153 is controlled so that the measured temperature becomes the set temperature.
　　（空調装置の制御処理の流れ（冷房運転時））
　次に本実施形態における空調装置の制御処理の一例について、図９を参照しながら説明する。図９は、本実施形態における空調装置の制御処理の流れを示すフローチャートである。なお、図９は、夏季において空調装置を冷房運転させる場合の例である。Ｓ１からＳ６の処理については実施形態１（図５参照）と同様であるのでここでは説明を省略する。 (Flow of control processing of air conditioner (during cooling operation))
Next, an example of the control processing of the air conditioner in the present embodiment will be described with reference to FIG. FIG. 9 is a flowchart showing a flow of control processing of the air conditioner in the present embodiment. In addition, FIG. 9 is an example in the case of air-conditioning operation of an air conditioner in summer. Since the processing from S1 to S6 is the same as that of the first embodiment (see FIG. 5), the description is omitted here.
　Ｓ６において第１消費電力量が第１閾値未満である場合（Ｎｏ）、制御部１５３は、制御対象の空調装置を示す空調装置識別情報に対応する周辺装置識別情報および第２閾値を周辺装置情報から読み出し、制御対象の空調装置の周辺に位置する空調装置を特定する（Ｓ１１）。 When the first power consumption amount is less than the first threshold value in S6 (No), the control unit 153 sets the peripheral device identification information and the second threshold value corresponding to the air conditioner identification information indicating the air conditioner to be controlled as the peripheral device information. The air conditioner located around the air conditioner to be controlled is specified (S11).
　次に、制御部１５３は、周辺装置識別情報で示される空調装置の電力計の計測データに基づいて、所定期間（例えば、現時刻から過去１０分遡った期間）の第２消費電力量を算出する。制御部１５３は、各空調装置２１～２８に対応する電力計６１～６８の過去の計測データを蓄積しておくことで、第２消費電力量を算出することができる。そして、制御部１５３は、算出した第２消費電力量とＳ１１で読み出した第２閾値とを比較する（Ｓ１２）。 Next, the control unit 153 calculates the second power consumption amount for a predetermined period (for example, a period 10 minutes past the current time) based on the measurement data of the power meter of the air conditioner indicated by the peripheral device identification information. To do. The control unit 153 can calculate the second power consumption amount by accumulating the past measurement data of the power meters 61 to 68 corresponding to the air conditioners 21 to 28, respectively. Then, the control unit 153 compares the calculated second power consumption amount with the second threshold value read in S11 (S12).
　第２消費電力量が第２閾値以上である場合（Ｓ１２でＹｅｓ）、制御部１５３は、周辺の空調装置が運転していると判断し、制御対象の空調装置を停止させる（Ｓ７）。一方、第２消費電力量が第２閾値未満である場合（Ｓ１２でＮｏ）、制御部１５３は、周辺の空調装置が停止していると判断し、Ｓ２の処理に移行する。すなわち、制御対象の空調装置について、空調能力を下げることなく、設定温度に応じた通常の運転をさせる。 If the second power consumption is equal to or greater than the second threshold (Yes in S12), the control unit 153 determines that the surrounding air conditioner is operating, and stops the controlled air conditioner (S7). On the other hand, when the second power consumption is less than the second threshold (No in S12), the control unit 153 determines that the surrounding air conditioner is stopped, and proceeds to the process of S2. That is, the air conditioner to be controlled is caused to perform a normal operation according to the set temperature without lowering the air conditioning capacity.
　例えば、制御対象の空調装置２６に対して、最も近い製造ライン１５が停止していたとしても、空調装置２６の周辺の空調装置２７（図８参照）が停止している場合には、空調装置２６を運転させる。一方、空調装置２６の周辺の空調装置２７（図８参照）が運転している場合には、空調装置２６を停止させる。これにより、隣接する空調装置２６および空調装置２７の両方が停止することによる、生産工場内の空調能力の極端な低下を防止できる。また、周辺の空調装置２７が運転している場合に空調装置２６を停止させることで無駄な電力消費を防止できる。 For example, even if the production line 15 closest to the air conditioner 26 to be controlled is stopped, if the air conditioner 27 (see FIG. 8) around the air conditioner 26 is stopped, the air conditioner 26 is operated. On the other hand, when the air conditioner 27 (see FIG. 8) around the air conditioner 26 is operating, the air conditioner 26 is stopped. Thereby, the extreme fall of the air-conditioning capability in a production factory by both the adjacent air-conditioning apparatus 26 and the air-conditioning apparatus 27 stopping can be prevented. Moreover, useless power consumption can be prevented by stopping the air conditioner 26 when the surrounding air conditioner 27 is operating.
　制御部１５３は、全ての空調装置２１～２８について、図９に示すＳ１からＳ１２の処理を実行する。 The control unit 153 executes the processes from S1 to S12 shown in FIG. 9 for all the air conditioners 21 to 28.
　このように、制御部１５３は、第２グループに属する空調装置の各々について、（１）当該空調装置に対応する第１ライン識別情報で示される製造ラインの第１消費電力量が第１閾値未満であり、かつ、当該空調装置に対応する周辺装置識別情報で示される空調装置の第２消費電力量が所定の第２閾値以上である場合に、当該空調装置を停止させ、（２）第１消費電力量が第１閾値以上である、または、第２消費電力量が第２閾値未満である場合に、空調能力を低下させることなく当該空調装置を運転させる。 As described above, the control unit 153 determines, for each of the air conditioners belonging to the second group, (1) the first power consumption amount of the production line indicated by the first line identification information corresponding to the air conditioner is less than the first threshold value. And when the second power consumption of the air conditioner indicated by the peripheral device identification information corresponding to the air conditioner is equal to or greater than a predetermined second threshold, the air conditioner is stopped, and (2) the first When the power consumption is greater than or equal to the first threshold or the second power consumption is less than the second threshold, the air conditioner is operated without reducing the air conditioning capacity.
　これにより、第２グループに属する空調装置２２～２４・２６～２８は、最も近くに設置された製造ラインが停止しており、かつ、周辺の空調装置が運転しているときに限り、冷房運転が停止される。その結果、生産工場内の空調能力の極端な低下を防止することができる。 As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group are in the cooling operation only when the nearest production line is stopped and the surrounding air conditioners are in operation. Is stopped. As a result, it is possible to prevent an extreme decrease in the air conditioning capacity in the production factory.
　　（空調装置の制御処理の流れ（暖房運転時））
　次に本実施形態における空調装置の制御処理の一例について、図１０を参照しながら説明する。なお、図１０は、冬季において空調装置２１～２８を暖房運転させる場合の例である。 (Flow of control processing of air conditioner (during heating operation))
Next, an example of the control processing of the air conditioner in the present embodiment will be described with reference to FIG. FIG. 10 shows an example in which the air conditioners 21 to 28 are operated for heating in winter.
　Ｓ１，Ｓ４～６，Ｓ８，Ｓ９の処理については図６に示す実施形態１と同様であるのでここでは説明を省略する。 Since the processing of S1, S4 to 6, S8, and S9 is the same as that of the first embodiment shown in FIG. 6, the description thereof is omitted here.
　Ｓ６において第１消費電力量が第１閾値以上である場合（Ｙｅｓ）、制御部１５３は、制御対象の空調装置を示す空調装置識別情報に対応する周辺装置識別情報および第２閾値を周辺装置情報から読み出し、制御対象の空調装置の周辺に位置する空調装置を特定する（Ｓ１１）。 When the first power consumption amount is greater than or equal to the first threshold in S6 (Yes), the control unit 153 sets the peripheral device identification information and the second threshold corresponding to the air conditioner identification information indicating the air conditioner to be controlled as the peripheral device information. The air conditioner located around the air conditioner to be controlled is specified (S11).
　次に、制御部１５３は、周辺装置識別情報で示される空調装置の電力計の計測データに基づいて、所定期間（例えば、現時刻から過去１０分遡った期間）の第２消費電力量を算出する。制御部１５３は、各空調装置２１～２８に対応する電力計６１～６８の過去の計測データを蓄積しておくことで、第２消費電力量を算出することができる。そして、制御部１５３は、算出した第２消費電力量とＳ１１で読み出した第２閾値とを比較する（Ｓ１２）。 Next, the control unit 153 calculates the second power consumption amount for a predetermined period (for example, a period 10 minutes past the current time) based on the measurement data of the power meter of the air conditioner indicated by the peripheral device identification information. To do. The control unit 153 can calculate the second power consumption amount by accumulating the past measurement data of the power meters 61 to 68 corresponding to the air conditioners 21 to 28, respectively. Then, the control unit 153 compares the calculated second power consumption amount with the second threshold value read in S11 (S12).
　第２消費電力量が第２閾値以上である場合（Ｓ１２でＹｅｓ）、制御部１５３は、周辺の空調装置が運転していると判断し、制御対象の空調装置を停止させる（Ｓ７）。一方、第２消費電力量が第２閾値未満である場合（Ｓ１２でＮｏ）、制御部１５３は、周辺の空調装置が停止していると判断し、Ｓ２の処理に移行する。すなわち、制御対象の空調装置を、空調能力を下げることなく、通常の設定温度に応じた運転をさせる。 If the second power consumption is equal to or greater than the second threshold (Yes in S12), the control unit 153 determines that the surrounding air conditioner is operating, and stops the controlled air conditioner (S7). On the other hand, when the second power consumption is less than the second threshold (No in S12), the control unit 153 determines that the surrounding air conditioner is stopped, and proceeds to the process of S2. That is, the air conditioner to be controlled is operated according to the normal set temperature without reducing the air conditioning capacity.
　制御部１５３は、全ての空調装置２１～２８について、図１０に示すＳ１からＳ１２の処理を実行する。 The control unit 153 executes the processing from S1 to S12 shown in FIG. 10 for all the air conditioners 21 to 28.
　このように、制御部１５３は、第２グループに属する空調装置の各々について、（１）当該空調装置に対応する第１ライン識別情報で示される製造ラインの第１消費電力量が所定の第１閾値以上であり、かつ、当該空調装置に対応する周辺装置識別情報で示される空調装置の第２消費電力量が所定の第２閾値以上である場合に、当該空調装置を停止させ、（２）第１消費電力量が第１閾値未満である、または、第２消費電力量が第２閾値未満である場合に、空調能力を低下させることなく当該空調装置を運転させる。 As described above, the control unit 153 has (1) the first power consumption of the production line indicated by the first line identification information corresponding to the air conditioner for the air conditioners belonging to the second group. If the second power consumption amount of the air conditioner indicated by the peripheral device identification information corresponding to the air conditioner is equal to or greater than the predetermined second threshold, the air conditioner is stopped, and (2) When the first power consumption amount is less than the first threshold value or the second power consumption amount is less than the second threshold value, the air conditioner is operated without reducing the air conditioning capability.
　これにより、第２グループに属する空調装置２２～２４・２６～２８は、最も近くに設置された製造ラインが稼動しており、かつ、周辺の空調装置が運転しているときに限り、暖房運転が停止される。その結果、生産工場内の空調能力の極端な低下を防止することができる。 As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group are heated only when the nearest production line is in operation and the surrounding air conditioners are in operation. Is stopped. As a result, it is possible to prevent an extreme decrease in the air conditioning capacity in the production factory.
　＜実施形態３＞
　本発明のさらに他の実施形態について説明する。なお、説明の便宜上、実施形態１と同様の機能を有する部材には実施形態１と同じ符号を付し、その説明を省略する。 <Embodiment 3>
Still another embodiment of the present invention will be described. For convenience of explanation, members having the same functions as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and description thereof is omitted.
　生産工場によっては、複数の製造ラインにおける稼動時の放熱量が異なる場合がある。例えば、ある製造ラインには加熱装置が含まれているが、その周辺の製造ラインには加熱装置が含まれていない場合がある。このような、加熱装置が含まれていない製造ラインの近傍に設置された空調装置は、当該製造ラインの周辺の加熱装置を含む製造ラインからの放熱による温度上昇を防止する役割を担っている。そのため、実施形態１のように、加熱装置が含まれていない製造ラインの停止に同期して、その近傍の空調装置を停止させると、生産工場内の空調能力が極端に低下してしまう可能性がある。本実施形態は、このような問題をも解消できる形態である。 Depending on the production plant, the heat dissipation during operation in multiple production lines may differ. For example, a production line may include a heating device, but a surrounding production line may not include a heating device. Such an air conditioner installed in the vicinity of a production line that does not include a heating device plays a role of preventing a temperature rise due to heat radiation from the production line including the heating device around the production line. Therefore, if the air conditioner in the vicinity thereof is stopped in synchronization with the stop of the production line that does not include the heating device as in the first embodiment, the air conditioning capability in the production factory may be extremely reduced. There is. In the present embodiment, such a problem can be solved.
　図１１は、本実施形態の制御システム２０１を示す図である。図１１に示されるように、本実施形態の制御装置２５０は、制御部５３の代わりに制御部２５３を、空調－ライン対応テーブル記憶部５２の代わりに空調－ライン対応テーブル記憶部２５２を備える点で実施形態１の制御装置５０と異なる。 FIG. 11 is a diagram showing the control system 201 of the present embodiment. As shown in FIG. 11, the control device 250 of this embodiment includes a control unit 253 instead of the control unit 53, and an air conditioning-line correspondence table storage unit 252 instead of the air-conditioning / line correspondence table storage unit 52. This is different from the control device 50 of the first embodiment.
　空調－ライン対応テーブル記憶部２５２は、第２グループに属する空調装置２２～２４・２６～２８の各々について、当該空調装置を示す空調装置識別情報と、当該空調装置の最も近い位置に設置された製造ラインを識別する第１ライン識別情報と、当該製造ラインの停止を判断するための第１閾値と、当該製造ラインの周辺に設置され、監視すべきラインとして選択された製造ラインである周辺製造ラインを識別する第２ライン識別情報と、周辺製造ラインの停止を判断するための第３閾値とを対応付けた空調－ライン対応テーブルを記憶する。図１２は、空調－ライン対応テーブル記憶部２５２が記憶する空調－ライン対応テーブルの一例を示す図である。 The air conditioner-line correspondence table storage unit 252 is installed for each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group at the position closest to the air conditioner identification information indicating the air conditioner. Peripheral manufacturing which is the first line identification information for identifying the production line, the first threshold value for determining the stop of the production line, and the production line installed around the production line and selected as the line to be monitored An air conditioning-line correspondence table in which second line identification information for identifying a line is associated with a third threshold value for determining the stop of a peripheral production line is stored. FIG. 12 is a diagram illustrating an example of the air conditioning-line correspondence table stored in the air conditioning-line correspondence table storage unit 252.
　なお、第３閾値は、対応する周辺製造ラインが運転（稼動）しているときの所定期間（例えば１０分間）における消費電力量よりも小さく、当該周辺製造ラインが運転停止しているときの所定期間における消費電力量よりもわずかに大きい値が設定されている。 Note that the third threshold value is smaller than the power consumption during a predetermined period (for example, 10 minutes) when the corresponding peripheral manufacturing line is operating (operating), and is the predetermined value when the peripheral manufacturing line is stopped. A value slightly larger than the power consumption during the period is set.
　周辺製造ラインとしては、例えば、加熱装置を含むような放熱量の大きい製造ラインが適宜選択される。なお、全ての空調装置に対して周辺製造ラインを設定する必要はなく、生産工場内のレイアウトに応じて、一部の空調装置に対してのみ監視対象製造ラインを設定すればよい。例えば、図１２に示されるように、空調装置２７については、第２ライン識別情報が設定されていない。これは、空調装置２７に最も近い製造ライン１６の周辺の製造ライン１５・１７が加熱装置を含んでおらず、放熱量が小さいため、監視する必要がないからである。また、空調装置２３のように、１つの空調装置に対して複数の第２ライン識別情報および第３閾値が設定されてもよい。 As the peripheral production line, for example, a production line with a large heat dissipation amount including a heating device is appropriately selected. Note that it is not necessary to set peripheral manufacturing lines for all air conditioners, and it is only necessary to set monitored production lines for some air conditioners according to the layout in the production factory. For example, as illustrated in FIG. 12, the second line identification information is not set for the air conditioner 27. This is because the production lines 15 and 17 around the production line 16 closest to the air conditioner 27 do not include a heating device, and the amount of heat radiation is small, so that monitoring is not necessary. Further, like the air conditioner 23, a plurality of second line identification information and third threshold values may be set for one air conditioner.
　空調－ライン対応テーブル記憶部２５２は、入力部５４へのユーザ入力に応じた空調－ライン対応テーブルを記憶する。そのため、生産工場１０内のレイアウトを変更した場合、ユーザは新たなレイアウトに応じた第１ライン識別情報および第２ライン識別情報の変更指示を入力部５４に入力し、空調－ライン対応テーブル記憶部２５２は入力に従って空調－ライン対応テーブルを更新する。 The air conditioning / line correspondence table storage unit 252 stores an air conditioning / line correspondence table corresponding to a user input to the input unit 54. Therefore, when the layout in the production factory 10 is changed, the user inputs an instruction to change the first line identification information and the second line identification information according to the new layout to the input unit 54, and the air conditioning-line correspondence table storage unit 252 updates the air conditioning-line correspondence table according to the input.
　制御部２５３は、実施形態１の制御部５３と同様に、グループに応じて各空調装置２１～２８を制御する。ただし、第２グループに属する空調装置２２～２４・２６～２８に対する制御処理が実施形態１と異なる。 The control unit 253 controls each of the air conditioners 21 to 28 according to the group, like the control unit 53 of the first embodiment. However, the control processing for the air conditioners 22 to 24 and 26 to 28 belonging to the second group is different from that of the first embodiment.
　制御部２５３は、第２グループに属する空調装置２２～２４・２６～２８の各々に対して、当該空調装置を示す空調装置識別情報に対応する第１ライン識別情報および第１閾値を空調－ライン対応テーブルから読み出す。制御部２５３は、読み出した第１ライン識別情報で示される製造ラインに接続された電力計の計測データに基づいて、所定期間（例えば、現時刻から過去１０分遡った期間）の第１消費電力量を算出し、第１閾値と比較する。そして、制御部２５３は、実施形態１と同様に、算出した第１消費電力量が第１閾値よりも低い場合に製造ラインが停止しているものと判断し、算出した第１消費電力量が第１閾値以上である場合に製造ラインが稼動しているものと判断する。制御部２５３は、暖房運転時に製造ラインが停止していると判断した場合、空調装置を運転させ、冷房運転時に製造ラインが稼動していると判断した場合、空調装置の運転させる。 The control unit 253 sets, for each of the air conditioners 22 to 24 and 26 to 28 belonging to the second group, the first line identification information and the first threshold value corresponding to the air conditioner identification information indicating the air conditioner. Read from the correspondence table. Based on the measurement data of the wattmeter connected to the production line indicated by the read first line identification information, the control unit 253 performs the first power consumption for a predetermined period (for example, a period that goes back 10 minutes from the current time). An amount is calculated and compared to a first threshold. Then, similarly to the first embodiment, the control unit 253 determines that the production line is stopped when the calculated first power consumption is lower than the first threshold, and the calculated first power consumption is If it is equal to or greater than the first threshold, it is determined that the production line is operating. The control unit 253 operates the air conditioner when it is determined that the production line is stopped during the heating operation, and operates the air conditioner when it is determined that the production line is operating during the cooling operation.
　一方、制御部２５３は、冷房運転時に製造ラインが停止していると判断した場合、もしくは、暖房運転時に製造ラインが稼動していると判断した場合、以下のような処理を行う。すなわち、制御部２５３は、制御対象の空調装置に対応する第２ライン識別情報および第３閾値を空調－ライン対応テーブルから読み出し、読み出した第２ライン識別情報で示される製造ラインの電力計の計測データに基づいて、所定期間（例えば、現時刻から過去１０分遡った期間）の消費電力量（以下、第３消費電力量という）を算出し、第３閾値と比較する。 On the other hand, when the control unit 253 determines that the production line is stopped during the cooling operation or when it is determined that the production line is operating during the heating operation, the control unit 253 performs the following processing. That is, the control unit 253 reads out the second line identification information and the third threshold corresponding to the air conditioner to be controlled from the air conditioning-line correspondence table, and measures the wattmeter of the production line indicated by the read second line identification information. Based on the data, a power consumption amount (hereinafter, referred to as a third power consumption amount) for a predetermined period (for example, a period 10 minutes past the current time) is calculated and compared with a third threshold value.
　上述したように、第３閾値は、対応する周辺製造ラインが運転（稼動）しているときの所定期間における消費電力量よりも小さく、当該周辺製造ラインが運転停止しているときの所定期間における消費電力量よりもわずかに大きい値が設定されている。そのため、算出した第３消費電力量が第３閾値よりも低い場合、制御部２５３は、周辺製造ラインが停止しているものと判断することができる。第３消費電力量が第３閾値以下である場合、制御部２５３は、周辺製造ラインが運転していると判断し、制御対象の空調装置を停止させずに運転させる。一方、第３消費電力量が第３閾値未満である場合、制御部２５３は、周辺製造ラインが停止していると判断し、制御対象の空調装置を停止させる。なお、制御部２５３により運転するように制御された空調装置は、測定温度が設定温度になるように動作制御される。 As described above, the third threshold value is smaller than the power consumption amount in a predetermined period when the corresponding peripheral manufacturing line is operating (operating), and in the predetermined period when the peripheral manufacturing line is stopped. A value slightly larger than the power consumption is set. Therefore, when the calculated third power consumption is lower than the third threshold, the control unit 253 can determine that the peripheral manufacturing line is stopped. When the third power consumption is equal to or less than the third threshold, the control unit 253 determines that the peripheral production line is in operation and operates the controlled air conditioner without stopping it. On the other hand, when the third power consumption amount is less than the third threshold, the control unit 253 determines that the peripheral manufacturing line is stopped, and stops the controlled air conditioner. The air conditioner controlled to operate by the control unit 253 is controlled so that the measured temperature becomes the set temperature.
　　（空調装置の制御処理の流れ（冷房運転時））
　次に本実施形態における空調装置の制御処理の一例について、図１３を参照しながら説明する。図１３は、本実施形態における空調装置の制御処理の流れを示すフローチャートである。なお、図１３は、夏季において空調装置を冷房運転させる場合の例である。Ｓ１からＳ６の処理については実施形態１（図５参照）と同様であるのでここでは説明を省略する。 (Flow of control processing of air conditioner (during cooling operation))
Next, an example of the control processing of the air conditioner in the present embodiment will be described with reference to FIG. FIG. 13 is a flowchart showing a flow of control processing of the air conditioner in the present embodiment. FIG. 13 is an example of a case where the air conditioner is operated for cooling in summer. Since the processing from S1 to S6 is the same as that of the first embodiment (see FIG. 5), the description is omitted here.
　Ｓ６において第１消費電力量が第１閾値未満である場合（Ｎｏ）、制御部２５３は、制御対象の空調装置を示す空調装置識別情報に対応する第２ライン識別情報および第３閾値が設定されているか否かを空調－ライン対応テーブルに基づいて判断する（Ｓ１３）。 When the first power consumption amount is less than the first threshold value in S6 (No), the control unit 253 sets the second line identification information and the third threshold value corresponding to the air conditioner identification information indicating the air conditioner to be controlled. Is determined based on the air-conditioning-line correspondence table (S13).
　空調装置識別情報に対応する第２ライン識別情報および第３閾値が設定されていない場合（Ｓ１３でＮｏ）、制御部２５３は、監視すべき周辺製造ラインがないものと判断し、制御対象の空調装置を停止させる（Ｓ７）。 When the second line identification information and the third threshold corresponding to the air conditioner identification information are not set (No in S13), the control unit 253 determines that there is no peripheral production line to be monitored, and controls the air conditioning to be controlled. The apparatus is stopped (S7).
　空調装置識別情報に対応する第２ライン識別情報および第３閾値が設定されている場合（Ｓ１３でＹｅｓ）、制御部２５３は、当該第２ライン識別情報および第３閾値を読み出す。読み出した第２ライン識別情報は、監視すべき周辺製造ラインを示している。そして、制御部２５３は、第２ライン識別情報で示される製造ラインの電力計の計測データに基づいて、所定期間（例えば、現時刻から過去１０分遡った期間）の第３消費電力量を算出する。制御部２５３は、算出した第３消費電力量と第３閾値とを比較する（Ｓ１４）。 When the second line identification information and the third threshold corresponding to the air conditioner identification information are set (Yes in S13), the control unit 253 reads out the second line identification information and the third threshold. The read second line identification information indicates the peripheral production line to be monitored. Then, the control unit 253 calculates the third power consumption amount for a predetermined period (for example, a period 10 minutes past the current time) based on the measurement data of the power meter of the production line indicated by the second line identification information. To do. The control unit 253 compares the calculated third power consumption amount with the third threshold value (S14).
　第３消費電力量が第３閾値未満である場合（Ｓ１４でＹｅｓ）、制御部２５３は、監視すべき周辺製造ラインが停止していると判断し、制御対象の空調装置を停止させる（Ｓ７）。一方、第３消費電力量が第３閾値以上である場合（Ｓ１４でＮｏ）、制御部２５３は、監視すべき周辺製造ラインが稼動していると判断し、Ｓ２の処理に移行する。すなわち、制御対象の空調装置を、空調能力を下げることなく、通常の設定温度に応じた運転をさせる。 When the third power consumption is less than the third threshold (Yes in S14), the control unit 253 determines that the peripheral production line to be monitored is stopped, and stops the controlled air conditioner (S7). . On the other hand, when the third power consumption is greater than or equal to the third threshold (No in S14), the control unit 253 determines that the peripheral manufacturing line to be monitored is operating, and proceeds to the process of S2. That is, the air conditioner to be controlled is operated according to the normal set temperature without reducing the air conditioning capacity.
　例えば、制御対象の空調装置２６に対して、最も近い製造ライン１５が停止していたとしても、その周辺の製造ライン１６（図１および図１２参照）が稼動している場合には、空調装置２６を運転させる。一方、周辺の製造ライン１６も停止している場合には、空調装置２６を停止させる。これにより、製造ライン１６が稼動され放熱している場合に、空調装置２６を運転させるため、生産工場内の空調能力の極端な低下を防止できる。また、製造ライン１６が停止している場合には、空調装置２６を停止させることで無駄な電力消費を防止できる。 For example, even if the nearest production line 15 is stopped with respect to the air conditioner 26 to be controlled, if the peripheral production line 16 (see FIGS. 1 and 12) is operating, the air conditioner 26 is operated. On the other hand, if the peripheral production line 16 is also stopped, the air conditioner 26 is stopped. Thereby, when the production line 16 is operated and dissipates heat, the air conditioner 26 is operated, so that an extreme decrease in the air conditioning capacity in the production factory can be prevented. Further, when the production line 16 is stopped, useless power consumption can be prevented by stopping the air conditioner 26.
　また、図１２に示されるように、複数の周辺製造ラインが設定されている空調装置２３については、Ｓ１４において次のように処理を行えばよい。制御部２５３は、周辺製造ラインごとに、第２ライン識別情報および第３閾値の組合せを読み出す。そして、組合せごとに、第２ライン識別情報で示される製造ラインの電力計の計測データから求めた第３消費電力量を第３閾値と比較する。全ての組合せにおいて第３消費電力量が第３閾値未満である場合にＳ１４でＹｅｓと判定し、それ以外の場合にＳ１４でＮｏと判定する。もしくは、少なくとも１つの組合せにおいて第３消費電力量が第３閾値未満である場合にＳ１４でＹｅｓと判定し、それ以外の場合にＳ１４でＮｏと判定してもよい。例えば、制御対象の空調装置２３については、製造ライン１１の第３消費電力量が第３閾値（１ｋＷ）未満であり、かつ、製造ライン１３の第３消費電力量が第３閾値（１ｋＷ）未満である場合にＳ７の処理に移行する。もしくは、製造ライン１１および製造ライン１２の少なくとも一方の第３消費電力量が第３閾値未満である場合にＳ７の処理に移行してもよい。 Further, as shown in FIG. 12, the air conditioner 23 in which a plurality of peripheral production lines are set may be processed as follows in S14. The control unit 253 reads out the combination of the second line identification information and the third threshold value for each peripheral production line. And the 3rd power consumption calculated | required from the measurement data of the wattmeter of the manufacturing line shown by 2nd line identification information for every combination is compared with a 3rd threshold value. In all combinations, if the third power consumption is less than the third threshold, it is determined Yes in S14, otherwise it is determined No in S14. Alternatively, when the third power consumption is less than the third threshold in at least one combination, it may be determined as Yes in S14, and may be determined as No in S14 in other cases. For example, for the air conditioner 23 to be controlled, the third power consumption of the production line 11 is less than the third threshold (1 kW), and the third power consumption of the production line 13 is less than the third threshold (1 kW). If so, the process proceeds to S7. Or you may transfer to the process of S7, when the 3rd power consumption of at least one of the production line 11 and the production line 12 is less than a 3rd threshold value.
　制御部２５３は、全ての空調装置２１～２８について、図１３に示すＳ１からＳ１４の処理を実行する。 The control unit 253 executes the processing from S1 to S14 shown in FIG. 13 for all the air conditioners 21 to 28.
　このように、制御部２５３は、第２グループに属する空調装置の各々について、（１）当該空調装置に対応する第１ライン識別情報で示される製造ラインの第１消費電力量が所定の第１閾値未満であり、かつ、当該空調装置に対応する第２ライン識別情報で示される周辺製造ラインの第３消費電力量が所定の第３閾値未満である場合に、当該空調装置を停止させ、（２）第１消費電力量が第１閾値以上である、または、第３消費電力量が第３閾値以上である場合に、空調能力を低下させることなく当該空調装置を運転させる。 As described above, the control unit 253, for each of the air conditioners belonging to the second group, (1) the first power consumption of the production line indicated by the first line identification information corresponding to the air conditioner is a predetermined first. When the third power consumption of the peripheral production line indicated by the second line identification information corresponding to the air conditioner is less than the threshold value and less than the predetermined third threshold value, the air conditioner is stopped, 2) When the first power consumption is greater than or equal to the first threshold or the third power consumption is greater than or equal to the third threshold, the air conditioner is operated without reducing the air conditioning capacity.
　これにより、第２グループに属する空調装置２２～２４・２６～２８は、最も近くに設置された製造ラインが停止しており、かつ、監視すべき周辺製造ラインも停止しているときに限り、停止される。その結果、生産工場内の空調能力の極端な低下を防止することができる。 As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group can be used only when the nearest production line is stopped and the peripheral production line to be monitored is also stopped. Stopped. As a result, it is possible to prevent an extreme decrease in the air conditioning capacity in the production factory.
　　（空調装置の制御処理の流れ（暖房運転時））
　次に本実施形態における空調装置の制御処理の一例について、図１４を参照しながら説明する。なお、図１４は、冬季において空調装置２１～２８を暖房運転させる場合の例である。 (Flow of control processing of air conditioner (during heating operation))
Next, an example of control processing of the air conditioner in the present embodiment will be described with reference to FIG. FIG. 14 shows an example in which the air conditioners 21 to 28 are operated for heating in winter.
　Ｓ１，Ｓ４～６，Ｓ８，Ｓ９の処理については図６に示す実施形態１と同様であるのでここでは説明を省略する。 Since the processing of S1, S4 to 6, S8, and S9 is the same as that of the first embodiment shown in FIG. 6, the description thereof is omitted here.
　Ｓ６において第１消費電力量が第１閾値以上である場合（Ｙｅｓ）、制御部２５３は、制御対象の空調装置を示す空調装置識別情報に対応する第２ライン識別情報および第３閾値が設定されているか否かを空調－ライン対応テーブルに基づいて判断する（Ｓ１３）。 When the first power consumption amount is greater than or equal to the first threshold value in S6 (Yes), the control unit 253 sets the second line identification information and the third threshold value corresponding to the air conditioner identification information indicating the controlled air conditioner. Is determined based on the air-conditioning-line correspondence table (S13).
　空調装置識別情報に対応する第２ライン識別情報および第３閾値が設定されていない場合（Ｓ１３でＮｏ）、制御部２５３は、監視すべき周辺製造ラインがないものと判断し、制御対象の空調装置を停止させる（Ｓ７）。 When the second line identification information and the third threshold corresponding to the air conditioner identification information are not set (No in S13), the control unit 253 determines that there is no peripheral production line to be monitored, and controls the air conditioning to be controlled. The apparatus is stopped (S7).
　空調装置識別情報に対応する第２ライン識別情報および第３閾値が設定されている場合（Ｓ１３でＹｅｓ）、制御部２５３は、当該第２ライン識別情報および第３閾値を読み出す。読み出した第２ライン識別情報は、監視すべき周辺製造ラインを示している。そして、制御部２５３は、第２ライン識別情報で示される製造ラインの電力計の計測データに基づいて、所定期間（例えば、現時刻から過去１０分遡った期間）の第３消費電力量を算出する。制御部２５３は、算出した第３消費電力量と第３閾値とを比較する（Ｓ１４）。 When the second line identification information and the third threshold corresponding to the air conditioner identification information are set (Yes in S13), the control unit 253 reads out the second line identification information and the third threshold. The read second line identification information indicates the peripheral production line to be monitored. Then, the control unit 253 calculates the third power consumption amount for a predetermined period (for example, a period 10 minutes past the current time) based on the measurement data of the power meter of the production line indicated by the second line identification information. To do. The control unit 253 compares the calculated third power consumption amount with the third threshold value (S14).
　第３消費電力量が第３閾値未満である場合（Ｓ１４でＹｅｓ）、制御部２５３は、監視すべき周辺製造ラインが停止していると判断し、Ｓ８の処理に移行する。すなわち、制御対象の空調装置を、空調能力を下げることなく、通常の設定温度に応じた運転をさせる。一方、第３消費電力量が第３閾値以上である場合（Ｓ１４でＮｏ）、制御部２５３は、監視すべき周辺製造ラインが稼動していると判断し、制御対象の空調装置を停止させる（Ｓ７）。 When the third power consumption is less than the third threshold (Yes in S14), the control unit 253 determines that the peripheral production line to be monitored is stopped, and proceeds to the process of S8. That is, the air conditioner to be controlled is operated according to the normal set temperature without reducing the air conditioning capacity. On the other hand, when the third power consumption is equal to or greater than the third threshold (No in S14), the control unit 253 determines that the peripheral production line to be monitored is operating and stops the controlled air conditioner ( S7).
　制御部２５３は、全ての空調装置２１～２８について、図１４に示すＳ１からＳ１４の処理を実行する。 The control unit 253 executes the processing from S1 to S14 shown in FIG. 14 for all the air conditioners 21 to 28.
　このように、制御部２５３は、第２グループに属する空調装置の各々について、（１）当該空調装置に対応する第１ライン識別情報で示される製造ラインの第１消費電力量が所定の第１閾値以上であり、かつ、当該空調装置に対応する第２ライン識別情報で示される周辺製造ラインの第３消費電力量が所定の第３閾値以上である場合に、当該空調装置を停止させ、（２）第１消費電力量が第１閾値未満である、または、第３消費電力量が第３閾値未満である場合に、空調能力を低下させることなく当該空調装置を運転させる。 As described above, the control unit 253, for each of the air conditioners belonging to the second group, (1) the first power consumption of the production line indicated by the first line identification information corresponding to the air conditioner is a predetermined first. If the third power consumption of the peripheral manufacturing line indicated by the second line identification information corresponding to the air conditioner is equal to or greater than a predetermined third threshold, the air conditioner is stopped, 2) When the first power consumption is less than the first threshold or the third power consumption is less than the third threshold, the air conditioner is operated without reducing the air conditioning capacity.
　これにより、第２グループに属する空調装置２２～２４・２６～２８は、最も近くに設置された製造ラインが稼動しており、かつ、監視すべき周辺製造ラインも稼動しているときに限り、停止される。その結果、生産工場内の空調能力の極端な低下を防止することができる。 As a result, the air conditioners 22 to 24 and 26 to 28 belonging to the second group can be used only when the nearest production line is in operation and the peripheral production line to be monitored is also in operation. Stopped. As a result, it is possible to prevent an extreme decrease in the air conditioning capacity in the production factory.
　＜変形例＞
　上記の説明では、制御部５３・１５３・２５３は、Ｓ７のステップにおいて、制御対象の空調装置を停止させるものとした。しかしながら、Ｓ７のステップにおいて、制御部５３・１５３・２５３は、制御対象の空調装置の空調能力を低下させる制御を行ってもよい。例えば、空調装置２４や空調装置２８のように２つの室外機と接続されている場合には、一方の室外機のみを停止させることで、空調装置２４・２８について、空調能力を低下させて運転させてもよい。 <Modification>
In the above description, the control units 53, 153, and 253 stop the air conditioner to be controlled in step S7. However, in the step of S7, the control units 53, 153, and 253 may perform control to reduce the air conditioning capability of the air conditioner to be controlled. For example, when connected to two outdoor units such as the air conditioner 24 and the air conditioner 28, the operation of the air conditioners 24 and 28 is performed by reducing the air conditioning capability by stopping only one of the outdoor units. You may let them.
　また、空調装置２４や空調装置２８のように２つの室外機と接続されており、Ｓ７において一方の室外機を停止することにより空調能力を低下させる場合、以下のような処理を行ってもよい。すなわち、Ｓ７において、２つの室外機のうち一方が既に停止しているか否かを判断する。そして、既に一方が停止している場合には、既に空調能力が低下しているため、残りの一方を停止させずにそのままの状態を維持する。一方、２つの室外機の両方が稼動している場合には、一方を停止させ、空調能力を低下させる。 Further, when the air conditioner 24 is connected to two outdoor units like the air conditioner 24 and the air conditioner 28 and the air conditioning capacity is reduced by stopping one of the outdoor units in S7, the following processing may be performed. . That is, in S7, it is determined whether one of the two outdoor units has already stopped. And when one has already stopped, since the air-conditioning capability has already fallen, the other one is maintained as it is without stopping. On the other hand, when both of the two outdoor units are operating, one of them is stopped to reduce the air conditioning capacity.

　また、インターネットを含む通信ネットワークを接続可能なシステム構成であれば、通信ネットワークからプログラムをダウンロードするように流動的にプログラムを担持する記録媒体であることが好ましい。 In addition, if the system configuration is capable of connecting to a communication network including the Internet, the recording medium is preferably a recording medium that fluidly carries the program so as to download the program from the communication network.
　さらに、このように通信ネットワークからプログラムをダウンロードする場合には、そのダウンロード用のプログラムは予め本体装置に格納しておくか、あるいは別な記録媒体からインストールされるものであることが好ましい。 Further, when the program is downloaded from the communication network in this way, it is preferable that the download program is stored in the main device in advance or installed from another recording medium.
　以上のように、本発明の制御装置は、複数の空調装置を制御する制御装置であって、前記複数の空調装置を第１グループと第２グループとに分け、前記第１グループに属する空調装置については、設備の稼動状態にかかわらず運転させ、前記第２グループに属する空調装置については、前記設備の稼動状態に応じて運転を制御する制御部を備えることを特徴とする。 As described above, the control device of the present invention is a control device for controlling a plurality of air conditioners, and the air conditioners belonging to the first group are divided into a first group and a second group. The air conditioner belonging to the second group is provided with a control unit that controls the operation according to the operating state of the equipment.
　上記の構成によれば、第２グループに属する空調装置については、前記設備の稼動状態に応じて運転を制御する。設備からの放熱量は、設備の稼動状態に依存している。そのため、設備の稼動状態に応じて第２グループの空調装置を運転させることにより、設備の放熱量に応じて第２グループの空調装置を運転させることができる。その結果、第２グループの空調装置については、設備からの放熱に応じて無駄な運転を避けることができ、省電力化を図ることができる。例えば、設備が停止し放熱がないときには、第２グループの空調装置の冷房運転を停止することで、無駄な運転を避けることができる。また、第１グループに属する空調装置は、設備の稼動状態に関係なく運転される。そのため、例えば冷房運転時には、設備が稼動していない場合でも、第１グループに属する空調装置により、生産工場内の温度が設定温度に保たれる。 According to the above configuration, the operation of the air conditioners belonging to the second group is controlled according to the operating state of the facility. The amount of heat released from the equipment depends on the operating state of the equipment. Therefore, by operating the second group of air conditioners according to the operating state of the facility, the second group of air conditioners can be operated according to the heat radiation amount of the facility. As a result, for the second group of air conditioners, useless operation can be avoided in accordance with heat radiation from the facility, and power saving can be achieved. For example, when the equipment is stopped and there is no heat radiation, useless operation can be avoided by stopping the cooling operation of the second group of air conditioners. The air conditioners belonging to the first group are operated regardless of the operating state of the equipment. Therefore, for example, at the time of cooling operation, the temperature in the production factory is maintained at the set temperature by the air conditioner belonging to the first group even when the equipment is not operating.
　このように、複数の空調装置を、設備の稼動状態にかかわらず運転させる第１グループと、設備の稼動状態に応じて運転制御される第２グループとに分けるという簡単な設定により、無駄な電力を消費することなく、生産工場の温度を一定に保つことができる。すなわち、特許文献１・２のような生産工場の条件によって変化する環境データを詳細に取得する必要がない。また、空調対象領域内の設備や空調装置のレイアウトが変更されたとしても、特許文献１・２のような環境データを再度取得する必要がない。 In this way, wasteful power is generated by a simple setting of dividing a plurality of air conditioners into a first group that is operated regardless of the operating state of the facility and a second group that is controlled according to the operating state of the facility. The temperature of the production plant can be kept constant without consuming energy. That is, it is not necessary to acquire in detail the environmental data that changes according to the conditions of the production factory as in Patent Documents 1 and 2. Further, even if the layout of the equipment and air conditioners in the air conditioning target area is changed, it is not necessary to acquire environmental data as in Patent Documents 1 and 2 again.
　以上から、設備からの放熱の状況に応じた適切な空調制御を簡易に行うことが可能な制御装置を実現することができる。 From the above, it is possible to realize a control device that can easily perform appropriate air-conditioning control according to the state of heat radiation from the facility.
　また、本発明の制御装置において、前記制御部は、前記設備の消費電力量に基づいて当該設備の稼動状態を判断し、その判断結果に応じて前記第２グループに属する空調装置の運転を制御してもよい。 In the control device of the present invention, the control unit determines an operating state of the facility based on the power consumption amount of the facility, and controls the operation of the air conditioners belonging to the second group according to the determination result. May be.
　上記の構成によれば、設備の消費電力量を計測するだけで、容易に設備の稼動状態を把握することができる。 According to the above configuration, it is possible to easily grasp the operating state of the facility simply by measuring the power consumption of the facility.
　例えば、前記空調装置が冷房運転をしており、前記制御部は、（１）前記設備の消費電力量が所定の第１閾値未満である場合に、前記第２グループに属する空調装置を停止させ、もしくは、空調能力を低下させて運転させ、（２）前記設備の消費電力量が前記第１閾値以上である場合に、前記第２グループに属する空調装置を、空調能力を低下させることなく運転させる。設備の消費電力量が第１閾値未満である場合、設備からの放熱量が相対的に小さくなる。そのため、前記第２グループに属する空調装置を停止させ、もしくは、空調能力を低下させて運転させることにより、空調対象領域を過度に冷やすことを防止することができ、第２グループの空調装置の省電力化を図ることができる。 For example, if the air conditioner is in cooling operation, and the control unit (1) stops the air conditioners belonging to the second group when the power consumption of the facility is less than a predetermined first threshold value. Or (2) When the power consumption of the facility is equal to or greater than the first threshold value, the air conditioners belonging to the second group are operated without reducing the air conditioning capacity. Let When the power consumption of the facility is less than the first threshold, the heat dissipation from the facility is relatively small. Therefore, it is possible to prevent the air-conditioning target area from being excessively cooled by stopping the air conditioners belonging to the second group or operating the air conditioners with a reduced air conditioning capacity. Electricity can be achieved.
　また、前記空調装置が暖房運転をしており、前記制御部は、（１）前記設備の消費電力量が所定の第１閾値以上である場合に、前記第２グループに属する空調装置を停止させ、もしくは、空調能力を低下させて運転させ、（２）前記設備の消費電力量が前記第１閾値未満である場合に、前記第２グループに属する空調装置を、空調能力を低下させることなく運転させる。設備の消費電力量が第１閾値以上である場合、設備からの放熱量が相対的に大きくなる。そのため、前記第２グループに属する空調装置を停止させ、もしくは、空調能力を低下させて運転させることにより、空調対象領域を過度に暖めることを防止することができ、第２グループの空調装置の省電力化を図ることができる。 The air conditioner is in a heating operation, and the control unit (1) stops the air conditioner belonging to the second group when the power consumption of the facility is equal to or greater than a predetermined first threshold value. Or (2) When the power consumption of the facility is less than the first threshold, the air conditioners belonging to the second group are operated without reducing the air conditioning capacity. Let When the power consumption of the facility is greater than or equal to the first threshold, the heat dissipation from the facility is relatively large. For this reason, it is possible to prevent the air-conditioning target area from being excessively warmed by stopping the air-conditioning apparatus belonging to the second group or operating with the air-conditioning capacity being lowered, thereby saving the air-conditioning apparatus of the second group. Electricity can be achieved.
　また、本発明の制御装置は、前記設備が複数であり、前記第２グループに属する空調装置の近傍に設置されている設備を識別する第１設備識別情報を記憶する設備識別情報記憶部を備え、前記制御部は、第１設備識別情報で示される設備の稼動状態に応じて、前記第２グループに属する空調装置の運転を制御してもよい。 The control device according to the present invention further includes a facility identification information storage unit that stores a plurality of facilities and stores first facility identification information for identifying facilities installed in the vicinity of the air conditioners belonging to the second group.
