Embodiment 1. FIG.
FIG. 1 is a block diagram showing a configuration of a first embodiment (Embodiment 1) of an alarm system according to the present invention. The configuration of the first embodiment will be described with reference to FIG. The alarm system 100 shown in FIG. 1 includes an alarm device 200, a window sensor 300, and a power measurement adapter 400.

  The window sensor 300 has a communication function by wireless communication or wired communication, and is a sensor that detects opening and closing of windows and doors. When the window sensor 300 detects the opening / closing of the window 500, the window sensor 300 transmits a sensor notification indicating opening or closing to the alarm system 100 using a communication function. Specifically, when it detects that it changed from the closed state to the open state, it sends a sensor notification indicating the open state. Moreover, if it detects that it changed from the open state to the closed state, the sensor notification which shows closure will be transmitted. The window 500 is an object to be monitored by the alarm system 100. There may be a plurality of monitoring targets, and in that case, a plurality of window sensors 300 may exist corresponding to the number of windows to be monitored. Further, instead of the window sensor 300 or in addition to the window sensor 300, a door sensor that detects opening and closing of the door may be installed.

  The power measurement adapter 400 is a device that has a communication function by wireless communication or wired communication and measures power consumption. The power measurement adapter 400 is installed in the power supply system of the air conditioner 600. The power measurement adapter 400 measures the power consumption of the air conditioner 600. The power measurement adapter 400 transmits the measured power consumption amount as power consumption information of the air conditioner 600 to the alarm device 200 using a communication function. Note that a power meter having an existing communication function may be used as the power measurement adapter 400.

  FIG. 2 is a block diagram showing a configuration of the alarm device shown in FIG. The configuration of the alarm device shown in FIG. 1 will be described with reference to FIG.

  The alarm device 200 includes a sensor notification detection unit 201, an operation state determination unit 202, a guard timer 203, a warning display unit 204, an alarm notification unit 205, and an alarm control unit 206.

  The sensor notification detection unit 201 receives a sensor notification indicating opening / closing of the window 500 from the window sensor 300. The sensor notification detection unit 201 outputs an opening notification or a closing notification according to the content of the received sensor notification.

  The driving state determination unit 202 includes a power consumption information collection unit 2021 and a power threshold setting unit 2022. In the operation state determination unit 202, the power consumption information collection unit 2021 collects power consumption information from the power measurement adapter 400. In the power threshold setting unit 2022, a power threshold is set in advance. The operation state determination unit 202 uses the power consumption information collected by the power consumption information collection unit 2021 and the power threshold value set by the power threshold setting unit 2022, so that the operation state of the air conditioner 600 (running / standby) ). The power threshold value 2022 may be set by the user.

  The guard timer 203 is a timer used for preventing a malfunction that generates an alarm when a window or door is opened for a short time. The guard timer 203 is set with a guard time, which is a time for avoiding a false alarm due to a short opening of a window or door. As the guard time, a predetermined time may be set in advance, or an arbitrary time may be set by the user.

  The warning display unit 204 displays a warning and visually alerts the user. The warning display unit 204 may be turned on with a red light. The alarm notification unit 205 outputs an alarm sound as an alarm to call attention. The alarm control unit 206 controls warnings and alarms. When the alarm control unit 206 displays a warning and outputs a warning, and inputs a warning stop request from a user operation or a closure notification from the sensor notification detection unit 201, the warning control unit 206 displays the warning and displays the warning. Stop output.

  FIG. 3 is a flowchart showing a process in which the alarm system shown in FIG. 1 issues an alarm. With reference to FIG. 3, a process in which the alarm system 100 issues an alarm will be described.

  When the window sensor 300 detects that the window 500 is opened, the window sensor 300 transmits a sensor notification indicating the opening to the alarm device 200. In the alarm device 200, when the sensor notification detection unit 201 receives a sensor notification indicating opening from the window sensor 300 (step S301), the operation state determination unit 202 determines the operation state of the air conditioner (step S302).

  The operation state of the air conditioner is the state of the air conditioner estimated from the power consumption of the air conditioner, and includes an “in operation” state and a “standby” state. When determining the operation state, in the operation state determination unit 202, the power consumption information collection unit 2021 requests the power measurement adapter 400 to transmit the power consumption information of the air conditioner 600. The power measurement adapter 400 transmits power consumption information indicating the power consumption of the air conditioner 600 being measured to the operation state determination unit 202. In the driving state determination unit 202, the power consumption information collection unit 2021 receives the power consumption information. The driving state determination unit 202 compares the power threshold set in the power threshold setting unit 2022 with the power consumption indicated by the power consumption information received by the power consumption information collection unit 2021.

  FIG. 4 is an explanatory diagram showing an example of setting the power threshold value. The power threshold value shown in FIG. 4 is set to a value larger than the standby power. The operating state determination unit 202 determines that the air conditioner is in operation if the power consumption is equal to or greater than the set power threshold, and the air conditioner is on standby if the power consumption is less than the set power threshold. Judge that it is inside.

  If it is determined in step S302 that the air conditioner is on standby, the alarm device 200 returns to the initial state because it is not necessary to issue an alarm. If it is determined in step S302 that the air conditioner is in operation, the guard timer 203 starts counting the guard time (step S303).

  FIG. 5 is a flowchart showing an example of the operation of the guard timer. The guard time counting operation shown in step S303 will be described with reference to FIG. The guard timer 203 starts counting the set guard time (step S501). When the window 500 is closed, the window sensor 300 transmits a sensor notification indicating the closure. When the sensor notification detection unit 201 receives a sensor notification indicating closing from the window sensor 300, the sensor notification detection unit 201 outputs a closing notification. If a closing notification is input while the guard timer 203 is counting, the counting is stopped assuming that the window is temporarily opened (step S502), and the alarm device 200 is initialized. Return to state. When the count for the set guard time is completed (step S503), the operating state determination unit 202 determines again that the air conditioner is operating (step S304), assuming that the opening of the window is not a temporary opening.

  In step S304, the same processing as in step S302 is performed on the operating state of the air conditioner to determine whether the air conditioner is in an operating state or in a standby state. If it is determined that the air conditioner is in a standby state, the alarm device 200 returns to the initial state. If it is determined that the air conditioner is in operation, the alarm control unit 206 performs control to issue an alarm (step S305). As a result, in order to warn the user that the window is open and that the air conditioner is in operation, a warning is displayed on the warning display unit 204 and an alarm is issued on the alarm notification unit 205 (step S306).

  Note that when the operation state determination unit 202 determines that the room temperature adjusting electrical device is in operation, the number of inputs of the opening notification or the closing notification from the sensor notification detection unit 201 is predetermined within a predetermined time. When it is confirmed that the number of times has been exceeded, the alarm control unit 206 may issue an alarm. Such control prevents an alarm from being issued when the user once opens a window for ventilation or the like.

  In step S305, when an alarm is issued, an alarm stop request from the user or a closing notification from the sensor notification detection unit 201 is input, and the alarm control unit 206 stops the alarm, and the alarm device 200 indicates returning to the initial state.

  In an alarm system equipped with such an alarm device, the alarm device judges the operating state of the air conditioner that cannot directly know the operating state from the power consumption measured by the power measuring adapter, and opens / closes the window from the window sensor. At the same time, it is determined whether or not to issue an alarm. The alarm is issued to the user only when the window is opened for a certain time or more despite the air conditioner being in operation. As a result, it is possible to warn the user of a situation in which the air adjustment efficiency and the air adjustment effect of the air conditioner are reduced, and it is possible to prompt the user to suppress wasteful energy consumption.

  If the release operation from the user is not performed even after a predetermined time has passed since the alarm was issued, the alarm control unit 206 of the alarm device 200 sets a pattern for issuing an alarm, such as issuing an alarm at regular intervals. It may be changed. In an alarm system equipped with such an alarm device, it is useless to change the alarm pattern in situations where it is assumed that the user will not notice the alarm (for example, when the user is away with the window open). Power consumption can be reduced.

  In the alarm system 100 of the present embodiment, the alarm device 200 may include only one of the alarm display unit 204 and the alarm notification unit 205. In the alarm system provided with such an alarm device, since the components of the alarm device are reduced, the size of the alarm device can be reduced.

Embodiment 2. FIG.

  In the first embodiment, the air conditioner 600 is the target of alarm control. For example, the electric heater 700 is also an electric device for room temperature adjustment for the purpose of adjusting indoor air (mainly heating), and the alarm control according to the present invention. Can be the target of. Even if the electric stove 700 is operated for heating in a room where cold outside air enters by opening windows and doors, the room temperature cannot be increased efficiently, and unnecessary energy is consumed.

  The power measurement adapter 400 is installed in the power supply system of the electric stove 700, and transmits power consumption information indicating the power consumption of the electric stove 700 being measured to the operation state determination unit 202. The operation state determination unit 202 compares the power threshold set in the power threshold setting unit 2022 with the power consumption amount indicated by the power consumption information received by the power consumption information collection unit 2021. Determine the driving condition. The alarm control unit 206 determines whether or not to issue an alarm based on the operation state of the electric stove 700 determined by the operation state determination unit determination unit 202 and the window opening / closing information detected by the window sensor 300. The alarm control unit 206 performs control to issue an alarm to the user only when the window is opened for a certain time or more despite the electric stove 700 being in operation.

  In such an alarm system, it is possible to warn the user of a situation where it can be estimated that the heating effect by the electric stove is weak, and it is possible to prompt the user to suppress unnecessary energy consumption.

  Instead of the electric heater 700, a room temperature adjusting electric device having an air adjusting function such as an air purifier or a humidifier may be used as an object of alarm control.

  Further, in each of the above embodiments, when the sensor notification indicating opening is received from the window sensor 300, the operation state determination unit 202 determines the operation state of the air conditioner. However, the operation state determination unit 202 determines the operation state of the air conditioner. May determine the open / closed state indicated by the sensor notification received from the window sensor 300.

  In each of the above embodiments, the alarm device 200 determines whether or not to issue an alarm based on the open / closed state of the window. However, if a door sensor is installed, the alarm device 200 determines whether the alarm is based on the open / closed state of the door. Judge whether to issue.
