Description

Air conditioner control and air conditioner system

This disclosure relates to a control device for an air conditioner and an air conditioner system.

When using a battery as a power source for a wireless communication device consisting of a control device and a device, it is desirable to reduce power consumption as much as possible. When an environmental measurement sensor such as a temperature sensor is mounted on a device, it is desirable to enable bidirectional communication between the control device and the device in order to enable setting and initialization of the threshold value of the sensor. ..

For example, in order to improve the power consumption of a wireless device, a method is known in which the device enters a sleep state, which is a low power consumption state. When the device is in the sleep state, the device slows down the clock speed or stops the operation of the microprocessor or the sensing unit, for example. This puts the device in a state where it cannot perform normal operations. When the device is in sleep mode, the device cannot also receive information from the control device. Two-way communication is possible by synchronizing the sleep cycle between the control device and the device. The sleep cycle represents a cycle in which a device transitions from a normal operating state to a sleep state, and the sleep cycle can be changed by changing the sleep state time (sleep time) (see, for example, Patent Document 1). ..

Japanese Unexamined Patent Publication No. 2018-85572

Synchronize the sleep cycle in an air conditioner equipped with multiple battery-powered devices equipped with temperature sensors, etc. that enable measurement of the installation environment, and a control device that collects information on those devices. This enables two-way communication.

By setting the sleep time of the device short, if the sleep cycle is set short, the control device can communicate with the device frequently. If the sleep cycle is set longer by setting the sleep time of the device longer, the control device communicates with the device less frequently.

In an environment where phenomena that cause temperature changes such as opening and closing doors, people coming in and out, or things coming in and out occur frequently, the temperature changes in the target space are drastic. In order to quickly reflect such temperature changes in the operation control of the air conditioning conditioner, it is necessary for the control device to monitor the sensor information with high frequency by shortening the sleep cycle. However, if the sleep cycle is shortened, there is a problem that the power consumption of the battery of the device increases.

Therefore, an object of the present disclosure is to reduce the power consumption of the battery of a battery-powered device that detects a change in the environment, and to quickly reflect the change in the environment in the operation control of the air conditioner. It is to provide a control device and an air conditioning system.

The control device of the air conditioner of the present disclosure can switch between a sleep state and a normal operating state, and has a wireless communication unit that wirelessly communicates with a battery-powered device equipped with a sensor, and a time of a sensor detection value. It is provided with a sleep control unit that reduces the sleep state time of the device within a range of a predetermined minimum value or more when the change is equal to or more than the first threshold value. The sleep control unit notifies the device of the sleep state time of the device through the wireless communication unit.

It is provided with a sleep control unit that increases the sleep state time of the device within a range of not less than a predetermined maximum value when the device is less than the first threshold value and the device is not affected by the disturbance. The sleep control unit notifies the device of the sleep state time of the device through the wireless communication unit.

Hereinafter, embodiments will be described with reference to the drawings.
Embodiment 1.
FIG. 1 is a diagram showing a configuration of an air conditioning system 1.

The air conditioning system 1 includes a control device 10 for an air conditioning device and a plurality of devices 20.
The control device 10 functions as a wireless communication master unit. The device 20 functions as a wireless communication slave unit. The control device 10 is an indoor unit controller that controls the indoor unit of the air conditioner, or a main controller that controls the entire unit including the indoor unit and the outdoor unit of the air conditioner.

The control device 10 includes a main control unit 19, a wireless communication unit 11, a sensor value history storage unit 12, a sleep schedule management unit 13, a sleep control unit 14, a sensor information management unit 15, and a communication unit 16. It is provided with an operation control unit 17. The device 20 includes a sensor 21, a wireless communication unit 22, and a main control unit 23.

The device 20 is driven by a battery. The device 20 can switch between a sleep state, which is a low power consumption state in which only the minimum necessary operation is performed, and a normal operation state, which is waked up from the sleep state. Under normal operating conditions, all functions included in the device 20 can be fully operated. With low power consumption information, some functions included in the device 20 can be operated. In the following description, the sleep state time may be referred to as a sleep time.

The main control unit 23 of the device 20 controls the sensor 21 and the wireless communication unit 22.
The sensor 21 functions as an environment measurement sensor that measures the indoor environment that is the air-conditioned space, or functions as a disturbance sensor that detects a disturbance that changes the indoor environment that is the air-conditioned space, or is an environment measurement sensor and a disturbance. Functions as a sensor.

Environmental measurement sensors are temperature sensors, humidity sensors, illuminance sensors, pressure sensors, noise sensors, motion sensors, door open / close sensors, and the like.

The disturbance sensor is a temperature sensor, humidity sensor, illuminance sensor, pressure sensor, noise sensor, human sensor, door open / close sensor, power consumption sensor, water detection sensor, gas meter, etc. For example, when a ventilator is used, a barometric pressure sensor can detect changes in air pressure in the room. When sunlight is incident into the room by opening and closing the curtain or opening and closing the door, the illuminance sensor can detect an increase in the illuminance in the room. When a new person enters the room, the motion sensor can detect the increase in the number of people. When electric power is used, heat generation in the room can be detected by the electric power sensor. When it rains, a humidity sensor or a water detection sensor can detect the rainfall. When a gas stove is used, a gas meter can detect heat generation in the room. When a person enters or leaves the room, the door open / close sensor can detect the inflow or outflow of heat into the room.

The main control unit 19 of the control device 10 controls the entire control device 10.
The wireless communication unit 11 of the control device 10 performs two-way wireless communication with the wireless communication unit 22 of the plurality of devices 20. As a wireless method, for example, Bluetooth (registered trademark) can be used.

FIG. 2 is a diagram showing the format of the communication packet 30 transmitted between the control device 10 and the device 20. The communication packet includes a device address, a function code, data, and an error check.

The device address is unique identification information assigned to each of the control device 10 and the device 20. For example, the control device 10 specifies the device address of the device when transmitting the request to the device 20. The function code is a code for identifying the request content or setting content from the control device 10, or a code for identifying the response content from the device 20. For example, the function code includes a code in which the control device 10 specifies the sleep time of the device 20, a code in which the control device 10 requests a temperature sensor value from the device 20, and a code in which the control device 10 executes initialization of the device 20. The device 20 has a code for responding to the control device 10 with the sensor value detected by the sensor 21, a code for the device 20 to transmit the remaining battery level of the device 20 to the control device 10, and the like. The data represents the content of the matter indicated by the function code. For example, when the control device 10 sets the sleep time of the device 20 to 10 seconds, 10 seconds is specified for the data. Error checking includes information for error detection and correction of transmitted data.

The sensor value history storage unit 12 stores the history of sensor values by the sensors 21 of the plurality of devices 20.

The sensor information management unit 15 manages the sensor information of the sensor 21 of the device 20. The sensor information includes an address, a type, a sleep time control designation, an installation position, a sensor threshold, and a distance threshold. The sensor information is registered in advance by collecting from other devices via the communication unit 16 or from the device 20 itself.

The address represents the address of the device 20 including the sensor 21. The type indicates whether the sensor 21 functions as an environmental measurement sensor, a disturbance sensor, or an environmental measurement sensor and a disturbance sensor. The designation of the sleep time control indicates whether or not the sleep time of the device 20 is to be changed according to the sensor value of the sensor 21. The installation position indicates the position of the device 20 including the sensor 21. When the position of the device 20 is fixed, the installation position is registered by the installer of the air conditioner. When the position of the device 20 changes, the installation position is registered by the information from the GPS (Global Positioning System) included in the device 20. The installation position may be indicated by the three-dimensional coordinates of the three-dimensional space with one point in the indoor space as the origin. When the sensor 21 is a disturbance sensor and the installation position is not registered, the influence of the disturbance may be applied to all the devices 20 when the disturbance occurs.

The sensor threshold is registered when the type is a disturbance sensor, or a disturbance sensor and an environment measurement sensor. The occurrence of disturbance may be detected when the sense value of the disturbance sensor is equal to or higher than the sensor threshold value. When the disturbance sensor is an indoor temperature sensor, the occurrence of disturbance may be detected when the room temperature changes by 3 ° C. or more from the reference value. When the disturbance sensor is a door open / close sensor, the occurrence of disturbance may be detected when the door open / close time is 10 seconds or longer. When the disturbance sensor is a motion sensor, the occurrence of disturbance may be detected when the number of people in the room is 5 or more. When the disturbance sensor is an outdoor temperature sensor, the occurrence of disturbance may be detected when the temperature becomes 5 ° C. or lower.

The distance threshold is registered when the type is a disturbance sensor, or a disturbance sensor and an environment measurement sensor. When the distance from the disturbance sensor is equal to or less than the distance threshold value and a disturbance occurs, it may be affected by the disturbance.

The sleep schedule management unit 13 manages the sleep state schedules of the plurality of devices 20. The sleep state schedule of the device 20 can be specified by the user. For example, the user can set a sleep state schedule from another device via the communication unit 16. For example, in an environment where 24-hour air conditioning is required and there is little disturbance, the user can improve the battery life of the device 20 by setting the sleep time of the device 20 to be long. For a time zone in which the sleep state schedule is not registered in the sleep schedule management unit 13, the sleep control unit 14 sets the sleep state schedule of the device 20 based on the sensor value of the sensor 21 of the device 20. Register in the sleep schedule management unit 13. Here, as the sensor value of the sensor 21, for example, the sensor value of the environment sensor or the sensor value of the door open / close sensor which is a disturbance sensor can be used.

When the control device 10 first initiates communication with the plurality of devices 20, the control device 10 has a predetermined order (for example, a younger device address) for the plurality of devices 20 stored in the sensor information management unit 15. The communication packet 30 in which the initial value (for example, 1 minute) of the sleep time (for example, 1 minute) is specified is transmitted. When the device 20 receives the communication packet including the sleep time from the control device 10, the device 20 transmits the communication packet including the response message to the communication packet to the control device 10. The control device 10 receives a communication packet including a response message from each device 20.

The operation control unit 17 determines a change in the indoor environment based on the sensor value included in the communication packet transmitted from the device 20, and controls the air conditioner according to the determination. When the sleep time is short and the sleep cycle is short, the sensor value is quickly transmitted from the device 20 to the control device 10, so that the operation control unit 17 quickly reacts to changes in the indoor environment and air. The harmonizer can be controlled.

(Control of sleep time)
In the time zone in which the sleep state schedule is not registered, the sleep control unit 14 changes the sleep time of the device 20 according to the change in the sensor value detected by the device 20.

The sleep control unit 14 reduces the sleep time of the device 20 within a range of a predetermined minimum value SMIN or more when the time change of the detection value (sensor value) of the sensor 21 is the first threshold value TH1 or more. Specifically, the sleep time is set as follows. The sleep control unit 14 sets the sleep time of the device 20 to the minimum value SMIN when the time change of the detection value (sensor value) of the sensor 21 is greater than or equal to the second threshold value TH2 larger than the first threshold value TH1. When the time change of the detection value (sensor value) of the sensor is equal to or more than the first threshold value TH1 and less than the second threshold value TH2, the sleep control unit 14 sets the sleep time of the device 20 to a predetermined first value. Decrease by ΔS1. When the sleep time of the reduced device 20 is less than the minimum value SMIN, the sleep control unit 14 sets the sleep time of the device 20 to the minimum value SMIN.

The sleep control unit 14 detects the occurrence of a disturbance when the sensor value of the disturbance sensor such as the door open / close detection sensor is equal to or higher than the sensor threshold value. The sleep control unit 14 determines that the device is affected by the disturbance when the occurrence of the disturbance is detected by the disturbance sensor and the distance between the device 20 and the disturbance sensor is equal to or less than the distance threshold value.

The sleep control unit 14 predetermineds the sleep time of the device 20 when the time change of the detected value (sensor value) of the sensor 21 is less than the first threshold value TH1 and the device 20 is not affected by the disturbance. Increase within the range of the maximum value SMAX or less. Specifically, the sleep time is set as follows. The sleep control unit 14 predetermineds the sleep time of the device 20 when the time change of the detected value (sensor value) of the sensor 21 is less than the first threshold value TH1 and the device 20 is not affected by the disturbance. The second value obtained is increased by ΔS2. When the sleep time of the increased device 20 exceeds the maximum value SMAX, the sleep control unit 14 sets the sleep time of the device 20 to the maximum value SMAX.

The sleep control unit 14 predetermineds the sleep time of the device 20 when the time change of the detected value (sensor value) of the sensor 21 is less than the first threshold value TH1 and the device 20 is affected by the disturbance. Decrease within the range of the minimum value SMIN or more. Specifically, the sleep time is set as follows. The sleep control unit 14 determines the sleep time of the device 20 in advance when the time change of the detection value (sensor value) of the sensor is less than the first threshold value TH1 and the device 20 is affected by the disturbance. It is also reduced by the first value ΔS1. When the sleep time of the reduced device 20 is less than the minimum value SMIN, the sleep control unit 14 sets the sleep time of the device 20 to the minimum value SMIN.

(Correction of sleep time due to proximity of sleep end time)
When the sleep end times of the plurality of devices 20 are close to each other, the sleep control unit 14 corrects the sleep time of the devices 20 so as not to be close to each other.

The sleep control unit 14 calculates the scheduled end time of the sleep state of the device 20 based on the set sleep time of the device 20. When the difference D from the scheduled end time of the sleep state of the device 20 is less than the predetermined time Tsd, the difference D is set to be greater than or equal to the predetermined time Tsd. Correct the sleep time of the device 20.

In the sleep control unit 14, the scheduled end time of the sleep state of the device 20 is less than the predetermined time Tsd, and the difference D from the scheduled end time of the sleep state of the other device is less than the predetermined time Tsd. When the scheduled time is earlier than the scheduled end time of the sleep state of the other device, the sleep time of the device 20 is shortened so that the difference D becomes equal to or greater than the predetermined time Tsd.

In the sleep control unit 14, the scheduled end time of the sleep state of the device 20 is less than the predetermined time Tsd, and the difference D from the scheduled end time of the sleep state of the other device is less than the predetermined time Tsd. When the scheduled time is later than the scheduled end time of the sleep state of the other device, the sleep state time of the device 20 is lengthened so that the difference D becomes equal to or longer than a predetermined time.

3 and 4 are flowcharts showing the procedure for setting the sleep schedule of the device 20 in the first embodiment. The processing of this flowchart is performed at regular time intervals between the control device 10 and the device to be controlled among the plurality of devices 20 in a time zone in which the sleep state schedule is not registered in the sleep schedule management unit 13. Executed when communication takes place. In the following description, the device to be controlled is referred to as device (1). It is assumed that the device (1) is defined as the sleep time control target in the sleep schedule management unit 13.

In step S101, the sleep control unit 14 of the control device 10 monitors the sensor value of the sensor 21 of the device (1) through the wireless communication unit 11.

In step S102, the sleep control unit 14 of the control device 10 reads the previous sensor value of the device (1) from the sensor value history storage unit 12.

In step S103, when the control device 10 communicates with the device (1) for the first time, the process proceeds to step S108. When the control device 10 makes a communication connection with the device (1) for the second time or later, the process proceeds to step S104.

In step S108, the sleep control unit 14 of the control device 10 sets the sleep time Tsp (1) of the device (1) to the initial value Si (for example, 1 minute). After that, the process proceeds to step S114.

In step S104, the sleep control unit 14 of the control device 10 compares the current sensor value with the previous sensor value. When the difference SA between the current sensor value and the previous sensor value is equal to or higher than the first threshold value TH1 (for example, 1 ° C.), the process proceeds to step S105. When the difference SA between the current sensor value and the previous sensor value is less than the first threshold value TH1, the process proceeds to step S106.

In step S105, when the difference SA between the current sensor value and the previous sensor value is greater than or equal to the second threshold value TH2 (for example, 2 ° C.), the process proceeds to step S107, and the current sensor value and the previous sensor are used. When the difference SA from the value is less than the second threshold value TH2, the process proceeds to step S109.

In step S106, in the sleep control unit 14 of the control device 10, the sensor value of the disturbance sensor stored in the sensor value history storage unit 12 is equal to or higher than the sensor threshold value of the disturbance sensor registered in the sensor information management unit 15. When the distance between the device (1) and the disturbance sensor is equal to or less than the distance threshold value, it is determined that the device (1) is affected by the disturbance. If it is determined to be affected by the disturbance, the process proceeds to step S109, and if it is determined not to be affected by the disturbance, the process proceeds to step S110.

In step S109, the sleep control unit 14 of the control device 10 sets the sleep time Tsp (1) shorter than the previous value by a predetermined first value ΔS1 (for example, 10 seconds). After that, the process proceeds to step S111.

In step S111, when the sleep time Tsp (1) of the device (1) is equal to or greater than the minimum value SMIN, the process proceeds to step S114, and when the sleep time Tsp (1) of the device (1) is less than the minimum value SMIN. The process proceeds to step S107.

In step S107, the sleep control unit 14 of the control device 10 sets the sleep time Tsp (1) of the device (1) to the minimum value SMIN. After that, the process proceeds to step S114.

In step S110, the sleep control unit 14 of the control device 10 sets the sleep time Tsp (1) of the device (1) longer than the previous value by a predetermined second value ΔS2. After that, the process proceeds to step S112.

In step S112, when the sleep time Tsp (1) of the device (1) is equal to or less than the maximum value SMAX, the process proceeds to step S114, and when the sleep time Tsp (1) of the device (1) exceeds the maximum value SMAX. The process proceeds to step S113.

In step S113, the sleep control unit 14 of the control device 10 sets the sleep time Tsp (1) to the maximum value SMAX.

The Si, TH1, TH2, ΔS1 and ΔS2 described above may be set to arbitrary values by other devices through the communication unit 16.

As described above, the sleep time Tsp (1) of the device (1) is tentatively determined. Next, a step of checking whether the sleep end time of the device (1) is close to that of the other device 20 will be described. This is because when a plurality of devices 20 end the sleep state at the same time and enter the normal state, the communication with the control device 10 is continued while the normal state is maintained until the other device 20 completes the communication with the control device 10. This is because the battery is wasted because it is necessary to wait.

In step S114, the sleep control unit 14 of the control device 10 sets the sleep time Tsp (1) of the device (1) according to the following equation, and the expected sleep end time Esp (1) of the device (1). ) Is calculated. Let Tn be the current time.

Esp (1) = Tn + Tsp (1)… (1)
Scheduled sleep end time of the device (1) Esp (1) is a scheduled time at which the device (1) ends sleep. Since the control device 10 must be in a state of being able to communicate at the sleep end time of the device (1), it is necessary to prevent a plurality of devices from ending the sleep at the same time.

In step S115, the sleep control unit 14 of the control device 10 reads out the scheduled sleep end time Esp of one or more other devices 20 stored in the sleep schedule management unit 13.

In step S116, the sleep control unit 14 of the control device 10 sets the device having the scheduled sleep end time Esp closest to the scheduled sleep end time Esp (1) of the device (1) as the device (R) to be compared. The scheduled sleep end time Esp of the device (R) is set as the scheduled sleep end time Esp (R) of the device to be compared.

In step S117, the sleep control unit 14 of the control device 10 determines whether or not the scheduled sleep end time Esp (1) of the device (1) and the scheduled sleep end time Esp (R) of the device (R) to be compared are close to each other. Find out. Specifically, in the sleep control unit 14 of the control device 10, the difference D between the scheduled sleep end time Esp (1) of the device (1) and the scheduled sleep end time Esp (R) of the device (R) to be compared is large. Check whether the time is less than the predetermined time Tsd.

That is, the sleep control unit 14 checks whether the following equation (2) or (3) is satisfied. Tsd is the time required for the control device 10 to set the sleep time of the device 20. This time includes time for monitoring sensor values, determining sleep time, and notifying sleep time.

When Esp (R) ≥ Esp (1), Esp (R) -Esp (1) <Tsd… (2)
When Esp (R) <Esp (1), Esp (1) -Esp (R) <Tsd… (3)
When the equation (2) or (3) is satisfied, the sleep control unit 14 sets the scheduled sleep end time Esp (1) of the device (1) and the scheduled sleep end time Esp (R) of the device (R) to be compared. ) Is close.

If it is determined in step S117 that they are close to each other, the process proceeds to step S118. If it is not determined to be close, the process proceeds to step S119.

In step S118, the sleep control unit 14 of the control device 10 sets the sleep time Tsp (1) of the device (1) to be long or short according to the following equation. As a result, the difference D between the scheduled sleep end time Esp (1) of the device (1) and the scheduled sleep end time Esp (R) of the device (R) to be compared is set to be equal to or longer than the predetermined time Tsd. Will be done.

When Esp (R) ≥ Esp (1), Tsp (1) = Tsp (1) -Tsd… (4)
When Esp (R) <Esp (1), Tsp (1) = Tsp (1) + Tsd… (5)
The sleep control unit 14 of the control device 10 recalculates the scheduled sleep end time Esp (1) of the device (1) according to the following equation. After that, the process proceeds to step S119.

Esp (1) = Tn + Tsp (1)… (6)
In step S121, the sleep control unit 14 of the control device 10 determines the sleep time Tsp (1) of the device (1). The sleep control unit 14 of the control device 10 transmits a communication packet specifying the sleep time Tsp (1) to the device (1) through the wireless communication unit 11.

In step S122, the control device 10 stores the sleep time Tsp (1) of the device (1) and the scheduled sleep end time Esp (1) in the sleep schedule management unit 13.

As described above, according to the present embodiment, the sleep time is set according to the time change of the sensor value transmitted from the device, so that the power consumption of the battery of the device is reduced and the change in the environment is aired. It can be quickly reflected in the operation control of the harmonizer.

Embodiment 2.
In the present embodiment, the sleep schedule management unit 13 stores a time zone in which the sleep time is fixed and a fixed sleep schedule in which the fixed sleep time in the time zone is defined. For example, the fixed sleep schedule defines a time zone from 17:00 to 24:00 and a fixed sleep time of 30 minutes from 17:00 to 24:00.

When the current time is included in the time zone determined by the fixed sleep schedule stored in the sleep schedule management unit 13, the sleep control unit 14 has a sleep time Tsp (1) based on the sensor value described in the first embodiment. ), Instead of the temporary setting (S101 to S113), the fixed sleep time DS is set to the sleep time Tsp (1) of the device (1). For example, by increasing the fixed sleep time DS, the battery life can be extended in the time zone determined by the fixed sleep schedule.

FIG. 5 is a flowchart showing the procedure for setting the sleep schedule of the device 20 in the second embodiment.

In step S201, the control device 10 starts communication with the device (1).
In step S202, if the time when the communication is started is included in the time zone determined by the fixed sleep schedule stored in the sleep schedule management unit 13, the process proceeds to step S203. If the time at which communication is started is not included in the time zone determined by the fixed sleep schedule, the process proceeds to step S204.

In step S203, the sleep control unit 14 of the control device 10 sets the fixed sleep time DS defined in the fixed sleep schedule to the sleep time Tsp (1) of the device (1). After that, the process proceeds to step S114.

In step S204, the process proceeds to step 101.
Embodiment 3.
In the present embodiment, the sleep control unit 14 of the control device 10 monitors the remaining battery level of the device (1). The user can select whether to turn on or off the power saving control of the device (1).

The control device 10 presets the sleep time Tsp (1) when the power saving control of the device (1) is set to ON (enabled) and the remaining battery level of the device (1) is equal to or less than the remaining amount threshold THB. Set to the set power saving time BS. This control is executed instead of the temporary setting (S101 to S113) of the sleep time Tsp (1) based on the sensor value described in the first embodiment.
