Abstract
In the present invention, the number of persons boarding/exiting an elevator installed in a building is calculated for each floor, and the average number of persons staying on each floor is obtained using the calculated number of persons boarding/exiting the elevator. Then, a unit power consumption is obtained by dividing the amount of power used for each floor by the average number of persons staying on the floor. This unit power consumption is output in time series. Thus, the unit power consumption for each floor can be easily obtained from the number of persons boarding/exiting the elevator.
Description
本発明は、ビル管理システム及びビル管理方法に関する。
The present invention relates to a building management system and a building management method.
従来、ビルの消費電力を管理する手法としては、例えば、ビルの管理者が、ビルの毎月の消費電力量の測定値や、毎月の電気料金の支払い金額を見て、適正かどうかを判断していた。例えば、一年前の同じ月よりも消費電力量が増えた場合に、その増え方が異常でないか、適正な範囲であるかなどを判断していた。
Conventionally, as a method of managing the power consumption of a building, for example, the building manager looks at the monthly measured power consumption of the building and the amount of monthly electricity bills paid, and judges whether it is appropriate or not. was For example, if the amount of power consumption increased compared to the same month one year ago, it was determined whether the increase was normal or within an appropriate range.
ところが、単にビル全体での消費電力量などを見ているだけでは、ビル内の各フロアの使われ方が適正かどうかを判断することは困難であった。
特許文献1には、ビルの各部屋の入退室人数を出入口で管理して、各部屋の在室人数を計算して、部屋のエネルギ消費量と在室人数から一人あたりのエネルギ消費量を算出して表示する技術が記載されている。 However, it was difficult to determine whether each floor in the building was being used appropriately by simply looking at the power consumption of the entire building.
InPatent Document 1, the number of people entering and exiting each room of a building is managed at the entrance and exit, the number of people in each room is calculated, and the energy consumption per person is calculated from the energy consumption of the room and the number of people in the room. and display technology.
特許文献1には、ビルの各部屋の入退室人数を出入口で管理して、各部屋の在室人数を計算して、部屋のエネルギ消費量と在室人数から一人あたりのエネルギ消費量を算出して表示する技術が記載されている。 However, it was difficult to determine whether each floor in the building was being used appropriately by simply looking at the power consumption of the entire building.
In
特許文献1に記載されるように、ビルの各部屋の入退室人数を、出入口のゲートなどで管理することで、各部屋の正確な在室人数が計算でき、部屋のエネルギ消費量と在室人数から一人あたりのエネルギ消費量を算出することができる。
As described in Patent Document 1, by managing the number of people entering and exiting each room of a building at the entrance gate, etc., the accurate number of people in each room can be calculated, and the energy consumption of the room and the number of people in the room can be calculated. Energy consumption per person can be calculated from the number of people.
しかしながら、ビル内の全ての部屋の出入口にゲートを設ける構成とした場合、ビル内に多数のゲートが必要であり、ビル内の入退管理装置の構成が複雑化して、システム構成が複雑化するという問題がある。また、ビル内にオープンスペースのような自由に出入りができるフロアがある場合には、そのフロアについては、在室人数の計測が不可能であり、特許文献1に記載された技術では一人あたりのエネルギ消費量の算出ができないという問題があった。
However, if gates are provided at the entrances and exits of all rooms in the building, a large number of gates are required in the building, which complicates the configuration of the entrance/exit control device in the building and complicates the system configuration. There is a problem. In addition, if there is a floor such as an open space in the building that can be freely entered and exited, it is impossible to measure the number of people in the room on that floor. There was a problem that energy consumption could not be calculated.
したがって、各部屋のゲートのような複雑なシステム構成を必要としない簡単な構成や処理により、ビルの一人あたりのエネルギ消費量を正確に推定できるようにすることが望まれていた。
Therefore, it was desired to be able to accurately estimate per capita energy consumption in a building with a simple configuration and processing that does not require a complicated system configuration such as gates for each room.

FIG. 5 is a flow chart showing the flow of processing for obtaining the unit power consumption of air conditioners on each floor of a building in the system of this example. Here, processing for obtaining the unit power consumption of the air conditioners on each floor of the
まず、エレベーター監視装置300の乗降人数算出部321は、ビル100aに設置されたエレベーター110のかご115の各フロアでの乗降人数を算出する(ステップS11)。この各フロアでの乗降人数は、例えば、かご115に取り付けられた荷重センサで検出された荷重値の、各フロアでの変化から推定される。例えば、かご115が特定のフロアに停止して、荷重センサが検出した荷重値が約110kg少なくなったとき、乗降人数算出部321は、2人がそのフロアで降りたと判断する。逆に、荷重センサが検出した荷重値が約170kg多くなったときには、乗降人数算出部321は、3人がそのフロアで乗車したと判断する。このエレベーター監視装置300の乗降人数算出部321が算出したフロアごとの乗降人数の情報は、乗降人数データベース301に記憶される。
First, the number-of-passengers calculation unit 321 of the elevator monitoring device 300 calculates the number of passengers on each floor of the car 115 of the elevator 110 installed in the building 100a (step S11). The number of passengers getting on and off on each floor is estimated, for example, from changes in load values detected by load sensors attached to the car 115 on each floor. For example, when the car 115 stops on a specific floor and the load value detected by the load sensor decreases by approximately 110 kg, the number-of-boarding/alighting number calculator 321 determines that two people got off on that floor. Conversely, when the load value detected by the load sensor increases by approximately 170 kg, the number-of-boarding/alighting number calculation unit 321 determines that three people have boarded the floor. Information on the number of passengers on each floor calculated by the passenger number calculation unit 321 of the elevator monitoring device 300 is stored in the passenger number database 301 .
そして、ビル設備制御品質管理装置200は、エレベーター監視装置300の乗降人数データベース301に記憶されたビル100aの各フロアでのエレベーターの乗降人数を読み出す。ビル設備制御品質管理装置200の滞留人数算出部221は、取得したエレベーターの各フロアの乗降人数を積算して、各フロアの時間帯ごとの平均滞留人数を算出する(ステップS12)。
Then, the building facility control quality management device 200 reads out the number of passengers on each floor of the building 100 a stored in the database 301 of the number of passengers on the elevator monitoring device 300 . The staying number calculation unit 221 of the building equipment control quality management apparatus 200 integrates the acquired number of passengers on each floor of the elevator to calculate the average staying number for each time period on each floor (step S12).
なお、ビル100aの出入口が設置された階(1階)の滞留人数については、滞留人数算出部221は、入退監視装置400がカウントしたビル全体の滞留人数から、1階を除く階の滞留人数を減算して算出する。また、出入口が設置された1階で入退管理が行われていないビルの場合には、滞留人数算出部221は、1階の滞留人数の算出を行わないようにしてもよい。
Regarding the number of people staying on the floor (first floor) where the entrance/exit of the building 100a is installed, the number of staying people calculation unit 221 calculates the number of people staying on the floors other than the first floor from the number of people staying on the entire building counted by the entrance/exit monitoring device 400. Calculate by subtracting the number of people. In addition, in the case of a building where entry/exit management is not performed on the first floor where the entrance/exit is installed, the staying number calculation unit 221 may not calculate the number of staying persons on the first floor.
次に、空調機監視装置500の電力使用量測定部521は、ビル100aの各フロアの時間帯ごとの空調機の電力消費量を測定し、稼働記録データベース501に記録する(ステップS13)。そして、ビル設備制御品質管理装置200は、空調機監視装置500の稼働記録データベース501に記録されたビル100aの各フロアの時間帯ごとの空調機の電力消費量を読み出す。
Next, the power consumption measurement unit 521 of the air conditioner monitoring device 500 measures the power consumption of the air conditioners for each time period on each floor of the building 100a and records it in the operation record database 501 (step S13). Then, the building equipment control quality management device 200 reads out the power consumption of the air conditioners for each time period on each floor of the building 100 a recorded in the operation record database 501 of the air conditioner monitoring device 500 .
ビル設備制御品質管理装置200の単位消費電力算出部222は、ビル100aの各フロアの時間帯ごとの空調機の電力消費量を、各フロアの時間帯ごとの平均滞留人数で除した値である単位消費電力を求める(ステップS14)。求めた単位消費電力の情報は、消費電力データベース201に記録される。
また、単位消費電力算出部222は、ステップS14で求めた各フロアの単位消費電力が、予め設定された一人あたりの単位消費電力の規定値を超えているか否かを判断する(ステップS15)。 The unit powerconsumption calculation unit 222 of the building equipment control quality management device 200 is a value obtained by dividing the power consumption of the air conditioner for each time period on each floor of the building 100a by the average number of staying people for each time period on each floor. A unit power consumption is obtained (step S14). The obtained unit power consumption information is recorded in the power consumption database 201 .
In addition, the unit powerconsumption calculation unit 222 determines whether or not the unit power consumption of each floor calculated in step S14 exceeds a preset value of unit power consumption per person (step S15).
また、単位消費電力算出部222は、ステップS14で求めた各フロアの単位消費電力が、予め設定された一人あたりの単位消費電力の規定値を超えているか否かを判断する(ステップS15)。 The unit power
In addition, the unit power
ステップS15で、単位消費電力の規定値を超えている場合(ステップS15のYes)、ビル設備制御品質管理装置200は、ビル100aの空調制御装置120に対して、単位消費電力の規定値を超えているフロアの空調機(空調機121~127のいずれか)の設定温度を変える指令を送る(ステップS16)。ここでの設定温度を変える指令は、該当するフロアの空調機の消費電力を下げるために行うものであり、例えば冷房運転時には、設定温度を上げる指令であり、暖房運転時には、設定温度を下げる指令になる。
In step S15, if the unit power consumption exceeds the specified value (Yes in step S15), the building equipment control quality management device 200 instructs the air conditioning control device 120 of the building 100a to A command to change the set temperature of the air conditioner (one of the air conditioners 121 to 127) on the floor where the floor is on is sent (step S16). The command to change the set temperature here is to reduce the power consumption of the air conditioner on the corresponding floor. become.
そして、ステップS15で、単位消費電力の規定値を超えていない場合(ステップS15のNo)と、ステップS16で設定温度を変える指令を送った後には、ビル設備制御品質管理装置200の出力部223は、ビル100aのフロアごとの単位消費電力の情報を、管理者端末600に出力する(ステップS17)。
管理者端末600は、ビル100aのフロアごとの単位消費電力の情報の表示を行う。ビル設備制御品質管理装置200の出力部223がビル100aのフロアごとの単位消費電力の情報を出力する際には、管理者端末600から指示された出力情報の選択に基づいて、出力情報の種類や形態などが選択される。 Then, in step S15, if the specified value of the unit power consumption is not exceeded (No in step S15), and after sending a command to change the set temperature in step S16, theoutput unit 223 of the building facility control quality management device 200 outputs the information of the unit power consumption for each floor of the building 100a to the administrator terminal 600 (step S17).
Theadministrator terminal 600 displays information on unit power consumption for each floor of the building 100a. When the output unit 223 of the building equipment control quality management device 200 outputs the information of the unit power consumption for each floor of the building 100a, based on the selection of the output information instructed from the administrator terminal 600, the type of output information and form are selected.

ステップS22で出力情報が「建物間比較」の場合には、出力部223は、比較するビルの指定を受付け(ステップS23)、比較する期間の指定を受付ける(ステップS24)。そして、出力部223は、指定された期間とビルの単位消費電力データの読み出しを消費電力データベース201に要求する(ステップS25)。そして、出力部223は、指定された期間とビルの単位消費電力データを消費電力データベース201から受け取る(ステップS26)。
When the output information is "comparison between buildings" in step S22, the output unit 223 accepts designation of buildings to be compared (step S23), and receives designation of the period to be compared (step S24). Then, the output unit 223 requests the power consumption database 201 to read the unit power consumption data for the designated period and building (step S25). Then, the output unit 223 receives the specified period and unit power consumption data of the building from the power consumption database 201 (step S26).
そして、出力部223は、比較するビルの単位消費電力データ選択を受付け(ステップS27)、指定されたビルの単位消費電力データの消費電力データベース201からの読み出しを行う(ステップS28)。
さらに、出力部223は、指定されたビルと比較するビルの単位消費電力を、対応付けたデータとして管理者端末600に出力する(ステップS29)。 Then, theoutput unit 223 receives the selection of the unit power consumption data of the building to be compared (step S27), and reads the unit power consumption data of the designated building from the power consumption database 201 (step S28).
Furthermore, theoutput unit 223 outputs the unit power consumption of the specified building and the building to be compared to the administrator terminal 600 as associated data (step S29).
さらに、出力部223は、指定されたビルと比較するビルの単位消費電力を、対応付けたデータとして管理者端末600に出力する(ステップS29)。 Then, the
Furthermore, the
また、ステップS22で出力情報が「相関」の場合には、出力部223は、期間の指定を受付ける(ステップS30)。また、出力部223は、相関を求める気象データの選択を受付ける(ステップS31)。ここでの相関を求める気象データには、期間内の各日の最高気温、不快指数などが含まれる。
Also, when the output information is "correlation" in step S22, the output unit 223 accepts designation of the period (step S30). The output unit 223 also accepts selection of weather data for which correlation is to be obtained (step S31). The meteorological data for which the correlation is to be obtained includes the maximum temperature of each day within the period, the discomfort index, and the like.
出力部223は、ステップS31で受付けた期間のビルが設置された地域の気象データを、気象情報サーバ700に対して要求し(ステップS32)、要求した気象データを受け取る(ステップS33)。
そして、出力部223は、指定された期間の気象データと、単位消費電力の相関グラフを作成して管理者端末600に出力する。 Theoutput unit 223 requests the weather information server 700 for the weather data of the area where the building is installed during the period accepted in step S31 (step S32), and receives the requested weather data (step S33).
Then, theoutput unit 223 creates a correlation graph between the weather data for the specified period and the unit power consumption, and outputs the graph to the administrator terminal 600 .

The power consumptions P21, P22, P23 of the lighting fixtures, outlets, and air conditioners shown in the bar graph in FIG. 12 are the same as the power consumptions P11, P12, P13 shown in FIG.
The line graph in FIG. 12 indicates the unit power consumption d22 per person on the corresponding floor. The unit power consumption d22 shown in FIG. 12 includes not only the power consumption of the air conditioner but also the power consumption of the lighting equipment and outlets. However, the building equipment control
単位消費電力量d22は、滞留人数が少ない早朝や夜間、ならびに昼休み時には高くなるが、それ以外の日中の時間帯では、空調機の稼働状況などを反映した値になる。なお、単位消費電力量d22はフロア全体での単位消費電力であるが、空調機だけの単位消費電力を算出した場合にも、ほぼ同様の変化を示す。
このようにフロアの一人あたりの単位消費電力量を算出して出力することで、ビルの各フロアでの空調機の運転が適正か否かを判断することができる。各フロアでの空調機の運転が適正か否かを判断できることで、各フロアが適正な滞留人数で適正な単位消費電力で使用されているか、あるいは、滞留人数に比べて空調機が強い状態で運転されているか、などが判るようになる。また、一人あたりの単位消費電力量が大きすぎる場合には、空調機の故障の可能性の判断も可能になる。 The unit power consumption d22 is high in the early morning, at night, and at lunchtime when there are few staying people, but in other time zones during the daytime, the value reflects the operation status of the air conditioner. Note that the unit power consumption d22 is the unit power consumption of the entire floor, but almost the same change is shown when the unit power consumption of only the air conditioner is calculated.
By calculating and outputting the unit power consumption per person on the floor in this way, it is possible to determine whether or not the operation of the air conditioners on each floor of the building is appropriate. By being able to determine whether the air conditioner is operating properly on each floor, it is possible to determine whether each floor is being used with an appropriate number of people and with an appropriate unit power consumption, or whether the air conditioning is strong compared to the number of people staying on each floor. It becomes possible to determine whether the vehicle is being driven or not. Moreover, when the unit power consumption per person is too large, it becomes possible to determine the possibility of failure of the air conditioner.

図13は、ビル設備制御品質管理装置200の出力部223が出力した情報の、管理者端末600での表示例を示す。
図13に示す表示画面は、左端に、期間及び時間帯の設定箇所があり、中央上部に、一日ごとのフロアの空調機の電力消費量P31(棒グラフ)と、一人あたりの一日の単位消費電力量d31(折れ線グラフ)とを、時系列でグラフ表示している。 FIG. 13 shows a display example of the information output by theoutput unit 223 of the building equipment control quality management apparatus 200 on the administrator terminal 600. As shown in FIG.
In the display screen shown in FIG. 13, the period and time period are set at the left end, and the power consumption P31 (bar graph) of the floor air conditioners for each day and the unit per person per day are displayed at the upper center. The power consumption d31 (line graph) is graphically displayed in chronological order.

In the display screen shown in FIG. 13, the period and time period are set at the left end, and the power consumption P31 (bar graph) of the floor air conditioners for each day and the unit per person per day are displayed at the upper center. The power consumption d31 (line graph) is graphically displayed in chronological order.
また、図13に示す表示画面の中央下部に、曜日ごとに示した一日のフロアの空調機の平均電力消費量P32(棒グラフ)と、一人あたりの曜日ごとの平均の単位消費電力量d32(折れ線グラフ)とを、時系列でグラフ表示している。
さらに、図13に示す表示画面の右側に、一人あたりの曜日ごとの単位電力量と、最高気温との関係をグラフで示す。気温として、最高気温を使用しているのは一例であり、最低気温や1日の平均気温などのその他の気温の指標を使ってもよい。 In addition, at the lower center of the display screen shown in FIG. 13, the average power consumption P32 (bar graph) of the air conditioners on the floor for each day of the week, and the average unit power consumption per person for each day of the week d32 ( line graph) are displayed in chronological order.
Furthermore, on the right side of the display screen shown in FIG. 13, a graph shows the relationship between the unit electric energy per person for each day of the week and the maximum temperature. Using the highest temperature as the temperature is an example, and other temperature indicators such as the lowest temperature and the average daily temperature may be used.

Using the highest temperature as the temperature is an example, and other temperature indicators such as the lowest temperature and the average daily temperature may be used.
この図13に示すように、一人あたりの一日の単位消費電力量を表示することで、ビルの各フロアでの電力消費や空調機の稼働状況が適正か否かを判断することができる。例えば、単位消費電力が既定値よりも多い場合に、空調機の設定温度を変化させて、単位消費電力を下げる処理が可能である。また、本例の場合には、エレベーターの各フロアの乗降人数から各フロアの滞留人数を算出するようにしたので、エレベーターが設置されたビルであれば、簡単に適用が可能である。
As shown in Fig. 13, by displaying the unit power consumption per person per day, it is possible to judge whether the power consumption and air conditioner operating conditions on each floor of the building are appropriate. For example, when the unit power consumption is higher than the default value, it is possible to change the set temperature of the air conditioner to lower the unit power consumption. In addition, in the case of this example, since the number of staying people on each floor is calculated from the number of people getting on and off the elevator on each floor, it can be easily applied to any building in which an elevator is installed.
なお、図13に示す表示は一例であり、より詳細な単位消費電力量を表示してもよい。例えば、図11や図12に示すグラフを表示するようにしてもよい。
また、図6のフローチャートのステップS22で建物間比較が選択された場合には、出力部223は、該当する複数のビルの単位消費電力の情報を記憶部230から読み出し、複数のビルの単位消費電力を比較できるように対応付けして表示されるように出力させる。これにより、特定のビルの各フロアの単位消費電力が、他のビルの各フロアの単位消費電力に比べて、どの程度であるか判断でき、管理者は、適正か否かが容易に判るようになる。
なお、この複数のビルの単位消費電力を比較する場合には、2つのビルの比較ではなく、例えば監視中の複数のビル(例えば監視中の全てのビル)の各フロアの平均の単位消費電力と、該当する1つのビルの各フロアの平均の単位消費電力とを比較してもよい。 Note that the display shown in FIG. 13 is an example, and more detailed unit power consumption may be displayed. For example, graphs shown in FIGS. 11 and 12 may be displayed.
Further, when the inter-building comparison is selected in step S22 of the flowchart of FIG. The power is output so as to be associated and displayed so that the power can be compared. This makes it possible to judge how much the unit power consumption of each floor of a specific building is compared to the unit power consumption of each floor of another building, and the administrator can easily determine whether it is appropriate or not. become.
When comparing the unit power consumption of multiple buildings, for example, the average unit power consumption of each floor of multiple buildings being monitored (for example, all buildings being monitored) is compared instead of comparing two buildings. may be compared with the average unit power consumption of each floor of the corresponding building.

また、図13の例では、曜日ごとに示した一日のフロアの空調機の平均電力消費量を集計して表示する例を示したが、このような集計処理は、ビル設備制御品質管理装置200の出力部223が行う場合と、管理者端末600が行う場合のいずれでもよい。
Also, in the example of FIG. 13, an example was shown in which the average power consumption of the air conditioners on the floor for each day of the week is aggregated and displayed. Either the output unit 223 of 200 or the administrator terminal 600 may be used.

なお、本発明は、上述した実施の形態例に限定されるものではなく、様々な変形例が含まれる。例えば、上記した実施の形態例は、本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。 <Modification>
It should be noted that the present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to those having all the described configurations.

It should be noted that the present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to those having all the described configurations.
例えば、図5のフローチャートでは、ステップS16で、単位消費電力が規定値以上のとき、空調機の設定温度を自動的に変化させて、単位消費電力を下げるようにした。これに対して、単位消費電力が規定値以上のとき、該当するビルの管理センタなどに通知を行って、実際に空調機の設定温度を変える操作は、ビル側の管理者が手動で行うようにしてもよい。
For example, in the flowchart of FIG. 5, in step S16, when the unit power consumption is equal to or higher than the specified value, the set temperature of the air conditioner is automatically changed to lower the unit power consumption. On the other hand, when the unit power consumption exceeds the specified value, the management center of the relevant building is notified, and the operation to actually change the set temperature of the air conditioner is to be done manually by the manager on the building side. can be
また、エレベーターの各フロアでの乗降人数の計測処理として、エレベーターのかごに設置された荷重センサの検出値を使用する点についても一例であり、その他の検出値を使ってもよい。例えば、エレベーター乗場やかご内に設置されたカメラ画像の画像解析で、各フロアの乗降人数を計測するようにしてもよい。また、荷重センサの検出値とエレベーター乗場やかご内に設置されたカメラ画像とを併用してもよい。
In addition, the use of the detected value of the load sensor installed in the elevator car as the process of measuring the number of people getting on and off on each floor of the elevator is an example, and other detected values may be used. For example, the number of passengers on each floor may be measured by image analysis of camera images installed in elevator halls and cars. Moreover, the detection value of the load sensor and the image of the camera installed in the elevator landing or the car may be used together.
さらに、各フロアでの滞留人数を算出する際には、ビル内の各フロア間の移動として階段や他の昇降機(エスカレーター)の使用を考慮するようにしてもよい。
例えば、エレベーターと階段が設置されたビルの場合に、ビル内での上りの移動時には、ほぼ全てのビル利用者がエレベーターを利用するものとして、エレベーターの上り運転時の乗降人数から、上りのフロア間移動の人数を算出する。一方、ビル内での下りの移動時には、一定比率、例えば10%程度は階段を利用するものとし、エレベーターの下り運転時の乗降人数に10%を乗算した人数から、下りのフロア間移動の人数を算出する。
このようにすることで、階段の利用がある場合でも、適正なフロア滞留人数の算出ができるようになる。なお、10%などの乗算する一定比率の値は、実際の運用を行いながら修正してもよい。 Furthermore, when calculating the number of people staying on each floor, the use of stairs or other elevators (escalators) may be taken into consideration as movement between floors in the building.
For example, in the case of a building with an elevator and stairs, assuming that almost all building users use the elevator when moving up in the building, the number of people getting on and off when the elevator goes up is calculated. Calculate the number of people traveling between On the other hand, when moving downhill in a building, a certain percentage, for example, about 10%, uses stairs. Calculate
By doing so, it is possible to calculate the appropriate number of people staying on the floor even when stairs are used. It should be noted that the constant multiplication value, such as 10%, may be corrected during actual operation.

By doing so, it is possible to calculate the appropriate number of people staying on the floor even when stairs are used. It should be noted that the constant multiplication value, such as 10%, may be corrected during actual operation.
また、エレベーター以外の昇降機の利用人数を利用して、フロアの滞留人数を算出してもよい。例えば、エスカレーターに設置された監視カメラや人感センサを使って、エスカレーターの利用者を計測し、計測した利用者数を、各フロアの滞留人数に加えるようにしてもよい。
Also, the number of people staying on the floor may be calculated using the number of people using elevators other than elevators. For example, the number of escalator users may be measured using surveillance cameras or motion sensors installed on the escalators, and the measured number of users may be added to the number of people staying on each floor.
また、図7や図8の例では、出入口が設置されたフロアの単位消費電力は算出しないようにしたが、入退監視装置400によってビル全体の入場者数や出場者数が判る場合には、ビル全体の滞留人数から、他のフロアの滞留人数を減算して、出入口が設置されたフロアの滞留人数、並びにそのフロアの単位消費電力を求めるようにしてもよい。
In addition, in the examples of FIGS. 7 and 8, the unit power consumption of the floor where the entrance/exit is installed is not calculated. Alternatively, by subtracting the number of people staying on other floors from the number of people staying on the entire building, the number of people staying on the floor where the entrance/exit is installed and the unit power consumption of that floor may be obtained.
また、ビル設備制御品質管理装置200が気象情報サーバ700から気温の情報を取得するようしたのは一例であり、その他の構成としてもよい。例えば、ビルに設置された空調機の室外機などに設置された温度測定部が計測した気温を、ビル設備制御品質管理装置200が収集する。そして、その収集した気温を消費電力データベース201に格納して、出力部223が、格納した情報に基づいて、単位消費電力と気温との相関を示すグラフを出力するようにしてもよい。
Also, it is an example that the building facility control quality management device 200 acquires temperature information from the weather information server 700, and other configurations may be used. For example, the building facility control and quality management device 200 collects temperatures measured by a temperature measuring unit installed in an outdoor unit of an air conditioner installed in a building. Then, the collected temperature may be stored in the power consumption database 201, and the output unit 223 may output a graph showing the correlation between the unit power consumption and the temperature based on the stored information.
さらにまた、図1~図4のブロック図では、制御線や情報線は説明上必要と考えられるものだけを示しており、製品上必ずしも全ての制御線や情報線を示しているとは限らない。実際には殆ど全ての構成が相互に接続されていると考えてもよい。また、図5及び図6に示すフローチャートにおいて、処理結果に影響を及ぼさない範囲で、複数の処理を同時に実行するか、あるいは処理順序を変更してもよい。
Furthermore, in the block diagrams of FIGS. 1 to 4, only control lines and information lines that are considered necessary for explanation are shown, and not all control lines and information lines are necessarily shown on the product. . In practice, it may be considered that almost all configurations are interconnected. In addition, in the flowcharts shown in FIGS. 5 and 6, a plurality of processes may be executed simultaneously or the order of the processes may be changed as long as the processing results are not affected.
