図3に示すように、第2閾値は、第1閾値と比較して大きな値が設定されている。このため、第1閾値に基づいた検知判定結果は、第2閾値に基づいた検知判定結果と比較した場合、人の在室の検出回数が多い。よって、第1閾値が閾値判定に用いられた場合、人感センサー部61の感度は上がり、第2閾値が閾値判定に用いられた場合、人感センサー部61の感度は下がる。したがって、人感センサー部61の感度を補正するには、閾値判定に用いる閾値が変更されればよい。
As shown in FIG. 3, the second threshold value is set to be larger than the first threshold value. For this reason, when the detection determination result based on the first threshold value is compared with the detection determination result based on the second threshold value, the number of times the person is present in the room is large. Therefore, when the first threshold value is used for threshold determination, the sensitivity of the human sensor unit 61 increases, and when the second threshold value is used for threshold determination, the sensitivity of the human sensor unit 61 decreases. Therefore, in order to correct the sensitivity of the human sensor unit 61, the threshold used for threshold determination may be changed.
例えば、温度に着目すると、夏場では室温と人体との温度差は小さい。つまり、人体から放出されている赤外線の強度は、周囲の外部環境と比べて相対的に弱い。この場合には、人感センサー部61の検知距離は縮む。一方、冬場では室温と人体との温度差は大きい。つまり、人体から放出されている赤外線の強度は、周囲の外部環境と比べて相対的に強い。この場合には、人感センサー部61の検知距離は伸びる。この結果、夏場と冬場とでは、人感センサー部61の検知結果にばらつきが生じる。そこで、夏場と冬場との人感センサー部61の検知結果のばらつきを抑制するために、冬場の検知感度を鈍らせることで、夏場と同様の検知距離が設定される。具体的には、夏場では第1閾値で閾値判定処理が実行され、冬場では第2閾値で閾値判定処理が実行される。
For example, focusing on temperature, in summer, the temperature difference between the room temperature and the human body is small. That is, the intensity of infrared rays emitted from the human body is relatively weak compared to the surrounding external environment. In this case, the detection distance of the human sensor unit 61 is shortened. On the other hand, in winter, the temperature difference between the room temperature and the human body is large. That is, the intensity of infrared rays emitted from the human body is relatively strong compared to the surrounding external environment. In this case, the detection distance of the human sensor 61 increases. As a result, the detection result of the human sensor unit 61 varies between summer and winter. Therefore, in order to suppress variations in detection results of the human sensor 61 between summer and winter, the detection distance similar to that in summer is set by dulling the detection sensitivity in winter. Specifically, the threshold determination process is executed with the first threshold in the summer, and the threshold determination process is executed with the second threshold in the winter.
また、例えば、湿度に着目すると、湿度が高い場合には、人体から放出されている赤外線の強度は、周囲の外部環境と比べて相対的に弱い。この場合には、人感センサー部61の検知距離は縮む。一方、湿度が低い場合には、人体から放出されている赤外線の強度は、周囲の外部環境と比べて相対的に強い。この場合には、人感センサー部61の検知距離は伸びる。この結果、湿度が高い場合と、湿度が低い場合とでは、人感センサー部61の検知結果にばらつきが生じる。そこで、湿度が高い場合と、湿度が低い場合との人感センサー部61の検知結果のばらつきを抑制するために、湿度が低い場合の検知感度を鈍らせることで、湿度が高い場合と同様の検知距離が設定される。具体的には、湿度が高い場合では第1閾値で閾値判定処理が実行され、湿度が低い場合では第2閾値で閾値判定処理が実行される。
Also, for example, focusing on humidity, when the humidity is high, the intensity of infrared rays emitted from the human body is relatively weak compared to the surrounding external environment. In this case, the detection distance of the human sensor unit 61 is shortened. On the other hand, when the humidity is low, the intensity of infrared rays emitted from the human body is relatively strong compared to the surrounding external environment. In this case, the detection distance of the human sensor 61 increases. As a result, the detection result of the human sensor unit 61 varies between when the humidity is high and when the humidity is low. Therefore, in order to suppress variations in the detection results of the human sensor unit 61 between when the humidity is high and when the humidity is low, the detection sensitivity when the humidity is low is dulled, which is the same as when the humidity is high. The detection distance is set. Specifically, when the humidity is high, the threshold determination process is executed with the first threshold, and when the humidity is low, the threshold determination process is executed with the second threshold.
また、例えば、照度に着目すると、照度が高い場合には、人体から放出されている赤外線の強度は、周囲の外部環境と比べて相対的に弱い。この場合には、人感センサー部61の検知距離は縮む。一方、照度が低い場合には、人体から放出されている赤外線の強度は、周囲の外部環境と比べて相対的に強い。この場合には、人感センサー部61の検知距離は伸びる。この結果、照度が高い場合と、照度が低い場合とでは、人感センサー部61の検知結果にばらつきが生じる。そこで、照度が高い場合と、照度が低い場合との人感センサー部61の検知結果のばらつきを抑制するために、照度が低い場合の検知感度を鈍らせることで、照度が高い場合と同様の検知距離が設定される。具体的には、照度が高い場合では第1閾値で閾値判定処理が実行され、照度が低い場合では第2閾値で閾値判定が実行される。
Also, for example, focusing on illuminance, when the illuminance is high, the intensity of infrared rays emitted from the human body is relatively weak compared to the surrounding external environment. In this case, the detection distance of the human sensor unit 61 is shortened. On the other hand, when the illuminance is low, the intensity of infrared rays emitted from the human body is relatively strong compared to the surrounding external environment. In this case, the detection distance of the human sensor 61 increases. As a result, the detection result of the human sensor unit 61 varies between when the illuminance is high and when the illuminance is low. Therefore, in order to suppress variations in the detection results of the human sensor unit 61 when the illuminance is high and when the illuminance is low, the detection sensitivity when the illuminance is low is dulled, and thus the same as when the illuminance is high The detection distance is set. Specifically, when the illuminance is high, the threshold determination process is executed with the first threshold, and when the illuminance is low, the threshold determination is executed with the second threshold.
要するに、人体から放出されている赤外線の強度が、周囲の外部環境と比べて相対的に強い場合には、人感センサー部61の閾値を第2閾値に設定することで、検知距離のばらつきが補正される。次に、周囲の外部環境を検知し、その検知結果に応じて人感センサー部61の閾値を補正する処理について図4及び図5を用いて説明する。
In short, when the intensity of the infrared rays emitted from the human body is relatively strong compared to the surrounding external environment, the threshold of the human sensor unit 61 is set to the second threshold, thereby causing variation in the detection distance. It is corrected. Next, processing for detecting the surrounding external environment and correcting the threshold value of the human sensor unit 61 according to the detection result will be described with reference to FIGS. 4 and 5.
図4は、本発明の実施の形態1における人感センサー部61の閾値の補正処理に利用する各種センサーのフラグを説明する図である。図4に示すように、温度センサー111では、温度閾値フラグが利用される。温度閾値フラグは、温度センサー111の検知結果が、予め設定された温度の閾値である温度閾値未満である場合に設定されるフラグである。例えば、温度閾値に5℃が閾値として設定されたと想定すると、温度センサー111の検知結果が5℃未満の場合、温度閾値フラグには1が設定される。
FIG. 4 is a diagram for explaining flags of various sensors used for threshold value correction processing of the human sensor 61 in Embodiment 1 of the present invention. As shown in FIG. 4, the temperature sensor 111 uses a temperature threshold flag. The temperature threshold flag is a flag that is set when the detection result of the temperature sensor 111 is less than a temperature threshold that is a preset temperature threshold. For example, assuming that 5 ° C. is set as the temperature threshold, if the detection result of the temperature sensor 111 is less than 5 ° C., 1 is set in the temperature threshold flag.
つまり、この場合は、5℃という閾値が、冬場であると判定する温度閾値として設定される。温度閾値と、温度センサー111の検知結果とが比較され、その比較結果に応じて、温度閾値フラグは設定される。温度閾値フラグは、人感センサー部61の検知感度を補正するか否かを判定する指標として設定される。
That is, in this case, a threshold value of 5 ° C. is set as a temperature threshold value for determining that it is a winter season. The temperature threshold is compared with the detection result of the temperature sensor 111, and the temperature threshold flag is set according to the comparison result. The temperature threshold flag is set as an index for determining whether to correct the detection sensitivity of the human sensor unit 61.
また、湿度センサー121では、湿度閾値フラグが利用される。湿度閾値フラグは、湿度センサー121の検知結果が、予め設定された湿度の閾値である湿度閾値未満である場合に設定されるフラグである。例えば、湿度閾値に20%が閾値として設定されと想定すると、湿度センサー121の検知結果が20%未満の場合、湿度閾値フラグには1が設定される。
In the humidity sensor 121, a humidity threshold flag is used. The humidity threshold flag is a flag that is set when the detection result of the humidity sensor 121 is less than a humidity threshold that is a preset humidity threshold. For example, assuming that 20% is set as the threshold for the humidity threshold, if the detection result of the humidity sensor 121 is less than 20%, 1 is set for the humidity threshold flag.
つまり、この場合は、20%という閾値が、湿度が低いと判定する湿度閾値として設定される。湿度閾値と、湿度センサー121の検知結果とが比較され、その比較結果に応じて、湿度閾値フラグは設定される。湿度閾値フラグは、人感センサー部61の検知感度を補正するか否かを判定する指標として設定される。
That is, in this case, a threshold value of 20% is set as a humidity threshold value for determining that the humidity is low. The humidity threshold and the detection result of the humidity sensor 121 are compared, and the humidity threshold flag is set according to the comparison result. The humidity threshold flag is set as an index for determining whether or not to correct the detection sensitivity of the human sensor unit 61.
また、照度センサー131では、照度閾値フラグが利用される。照度閾値フラグは、照度センサー131の検知結果が、予め設定された照度の閾値である照度閾値未満である場合に設定されるフラグである。例えば、照度閾値に50ルクスが閾値として設定されたと想定すると、照度センサー131の検知結果が50ルクス未満の場合、照度閾値フラグには1が設定される。
In the illuminance sensor 131, an illuminance threshold flag is used. The illuminance threshold flag is a flag that is set when the detection result of the illuminance sensor 131 is less than an illuminance threshold that is a preset illuminance threshold. For example, assuming that 50 lux is set as the illuminance threshold, when the detection result of the illuminance sensor 131 is less than 50 lux, 1 is set in the illuminance threshold flag.
つまり、この場合は、50ルクスという閾値が、照度が低いと判定する照度閾値として設定される。照度閾値と、照度センサー131の検知結果とが比較され、その比較結果に応じて、照度閾値フラグは設定される。照度閾値フラグは、人感センサー部61の検知感度を補正するか否かを判定する指標として設定される。
That is, in this case, a threshold value of 50 lux is set as the illuminance threshold value for determining that the illuminance is low. The illuminance threshold is compared with the detection result of the illuminance sensor 131, and the illuminance threshold flag is set according to the comparison result. The illuminance threshold flag is set as an index for determining whether or not to correct the detection sensitivity of the human sensor unit 61.
また、焦電型赤外線センサー101では、閾値補正フラグが利用される。閾値補正フラグは、温度閾値フラグ、湿度閾値フラグ、及び照度閾値フラグの何れかが1である場合、1が設定されるフラグである。つまり、閾値補正フラグは、温度閾値フラグ、湿度閾値フラグ、及び照度閾値フラグの論理和演算の結果が設定される。なお、上記で説明した各種フラグの設定例及び各種閾値の設定例は一例を示し、特にこれに限定しない。
In the pyroelectric infrared sensor 101, a threshold correction flag is used. The threshold correction flag is a flag that is set to 1 when any one of the temperature threshold flag, the humidity threshold flag, and the illuminance threshold flag is 1. That is, the threshold correction flag is set with the result of the logical sum operation of the temperature threshold flag, the humidity threshold flag, and the illuminance threshold flag. Note that the setting examples of various flags and the setting examples of various threshold values described above are merely examples, and the present invention is not particularly limited thereto.
次に、上記で説明した温度センサー111、湿度センサー121、及び照度センサー131のそれぞれの検知結果を周囲の外部環境の変化として利用することで、人感センサー部61の検知感度を補正する処理について図5を用いて説明する。図5は、本発明の実施の形態1におけるリモートコントローラー31の制御例を説明するフローチャートである。なお、後述するステップS11~ステップS23の処理は前処理工程として、各種フラグが設定される。また、後述するステップS24~ステップS28の処理は後処理工程として、設定された各種フラグに基づいて、人感センサー部61の検知感度が補正される。
Next, a process for correcting the detection sensitivity of the human sensor unit 61 by using the detection results of the temperature sensor 111, the humidity sensor 121, and the illuminance sensor 131 described above as changes in the surrounding external environment. This will be described with reference to FIG. FIG. 5 is a flowchart for explaining a control example of the remote controller 31 according to the first embodiment of the present invention. Note that various flags are set as pre-processing steps in steps S11 to S23 described later. In addition, the processing of steps S24 to S28 described later is a post-processing step, and the detection sensitivity of the human sensor unit 61 is corrected based on various set flags.

It becomes composition to do.

図6は、本発明の実施の形態2における人感センサー部61の閾値の補正処理に利用する各種フラグの一例を説明する図である。図6に示すように、日付の判定として日付判定フラグが利用される。日付判定フラグは、プロセッサ71が計時部87から取得した日付データに相当するコードがメモリ85に予め設定された設定日付である場合、1が設定されるフラグである。設定日付は、例えば、ユーザーにより設定される日付であり、スケジュール運転の設定に利用される。
FIG. 6 is a diagram illustrating an example of various flags used for threshold value correction processing of the human sensor unit 61 according to Embodiment 2 of the present invention. As shown in FIG. 6, a date determination flag is used for date determination. The date determination flag is a flag that is set to 1 when the code corresponding to the date data acquired by the processor 71 from the timekeeping unit 87 is a set date preset in the memory 85. The set date is, for example, a date set by the user, and is used for setting scheduled operation.
また、時間の判定として時間判定フラグが利用される。時間判定フラグは、プロセッサ71が計時部87から取得した時間データに相当するコードがメモリ85に予め設定された設定時間である場合、1が設定されるフラグである。設定時間は、例えば、ユーザーにより設定される時間であり、スケジュール運転の設定に利用される。
Also, a time determination flag is used for time determination. The time determination flag is a flag that is set to 1 when the code corresponding to the time data acquired from the time measuring unit 87 by the processor 71 is a preset time set in the memory 85. The set time is, for example, a time set by the user, and is used for setting scheduled operation.
また、季節の判定として季節判定フラグが利用される。季節判定フラグは、プロセッサ71が計時部87から取得した季節データに相当するコードがメモリ85に予め設定された設定季節である場合、1が設定されるフラグである。設定季節は、例えば、ユーザーにより設定される季節であり、スケジュール運転の設定に利用される。
Also, the season judgment flag is used as the season judgment. The season determination flag is a flag that is set to 1 when the code corresponding to the season data acquired from the time measuring unit 87 by the processor 71 is a preset season preset in the memory 85. The set season is, for example, a season set by the user, and is used for setting scheduled operation.
閾値補正フラグは実施の形態1と同様である。つまり、閾値補正フラグは、日付判定フラグ、時間判定フラグ、及び季節判定フラグの何れかが1である場合、1が設定されるフラグである。つまり、閾値補正フラグは、日付判定フラグ、時間判定フラグ、及び季節判定フラグの論理和演算の結果が設定される。なお、上記で説明した各種フラグの設定例は一例を示し、特にこれに限定しない。
The threshold correction flag is the same as in the first embodiment. That is, the threshold correction flag is a flag that is set to 1 when any of the date determination flag, the time determination flag, and the season determination flag is 1. That is, the threshold correction flag is set with the result of the logical sum operation of the date determination flag, the time determination flag, and the season determination flag. Note that the setting examples of the various flags described above are merely examples, and the present invention is not particularly limited thereto.
図7は、本発明の実施の形態2におけるリモートコントローラー31の制御例を説明するフローチャートである。なお、後述するステップS51~ステップS63の処理は前処理工程として、各種フラグが設定される。また、後述するステップS64~ステップS68の処理は後処理工程として、設定された各種フラグに基づいて、人感センサー部61の検知感度が補正される。
FIG. 7 is a flowchart illustrating a control example of the remote controller 31 according to the second embodiment of the present invention. Note that various flags are set as pre-processing steps in steps S51 to S63 described later. Further, the processing of steps S64 to S68 described later is a post-processing step, and the detection sensitivity of the human sensor unit 61 is corrected based on various set flags.

上記の説明から、周囲の外部環境に応じて人感センサー部61の検知感度を補正するので、人感センサー部61のばらつきを抑制することができる。また、人感センサー部61のばらつきを抑制した状態でリモートコントローラー31から室内ユニット21に各種信号が送信されるので、室内ユニット21及び室外ユニット11の運転効率を向上させることができる。
From the above description, since the detection sensitivity of the human sensor unit 61 is corrected according to the surrounding external environment, variations in the human sensor unit 61 can be suppressed. In addition, since various signals are transmitted from the remote controller 31 to the indoor unit 21 in a state where variations in the human sensor unit 61 are suppressed, the operating efficiency of the indoor unit 21 and the outdoor unit 11 can be improved.
以上、本実施の形態3においては、リモートコントローラー31と、リモートコントローラー31からの制御指令により制御される室外ユニット11及び室内ユニット21とを備える構成となる。
As mentioned above, in this Embodiment 3, it becomes the structure provided with the remote controller 31, the outdoor unit 11 and the indoor unit 21 which are controlled by the control command from the remote controller 31.
よって、人感センサー部61のばらつきを抑制することができる。また、リモートコントローラー31に人感センサー部61が設けられているため、空調機に人感センサー部61が設けられていなかったとしても、人の不在をリモートコントローラー31で検知できる。よって、リモートコントローラー31を用いることで、人感センサー部61を搭載しない空調機であったとしても、人の存否確認処理を行うことができるため、運転効率を向上させることができる。
Therefore, the variation of the human sensor 61 can be suppressed. Moreover, since the human sensor 61 is provided in the remote controller 31, even if the human sensor 61 is not provided in the air conditioner, the absence of a person can be detected by the remote controller 31. Therefore, by using the remote controller 31, even if the air conditioner does not include the human sensor unit 61, it is possible to perform a human presence confirmation process, and thus it is possible to improve driving efficiency.
なお、本実施の形態1~3は、単独で実施されてもよく、組み合わせて実施されてもよい。いずれの場合においても、上記で説明した有利な効果を奏することとなる。
