The following describes an embodiment of the air conditioning control system and air conditioning control method of the present invention with reference to the drawings.

First Embodiment
1 is an overall configuration diagram of an air conditioning control system S of the first embodiment. The air conditioning control system S includes a gateway device 10, a cloud server 20, an air conditioning operation terminal 30, and an air conditioner 40.

The gateway device 10 is connected to the air conditioner 40 via a communication path 1, and sets the air conditioner operating state and target values for each air conditioner control, such as temperature, humidity, and air volume, and acquires each parameter of the air conditioner 40. The communication path 1 is a communication line for air conditioner control or a general communication network.

Even if there are multiple air conditioners 40, the gateway device 10 can identify and communicate with each individual air conditioner 40 using an identifier (ID (Identifier)). The gateway device 10 can communicate with the cloud server 20 via a communication path 2. The communication path 2 is a communication path using an Internet line, and may be a wired connection such as an optical fiber communication network or an Ethernet (registered trademark) connection, or a wireless communication network such as a mobile communication carrier line. In addition, the Internet connection may use any of various communication protocols such as TCP/IP (Transmission Control Protocol/Internet Protocol), UDP/IP (User Datagram Protocol/Internet Protocol), and HTTP (Hyper Text Transfer Protocol)/HTTPS (Hyper Text Transfer Protocol Secure).

The gateway device 10 can communicate with an air conditioning operation terminal 30 for operating the air conditioner 40 via a communication path 3. The communication path 3 may be a communication line for air conditioning control, or a communication line for connecting building equipment such as BACnet (Building Automation and Control Networking protocol) (BACnet/IP (Internet Protocol), BACnet/WS (Web Services)). A request to change the setting value of the air conditioner 40 based on the user's operation of the air conditioning operation terminal 30, and a response to the request, are transmitted and received between the gateway device 10 and the air conditioning operation terminal 30 via the communication path 3.

FIG. 2 is a functional configuration diagram of the gateway device 10 of the first embodiment. The gateway device 10 includes communication units 101, 102, and 103 as communication means for communicating via communication paths 1, 2, and 3, respectively. The communication units 101 to 103 are communication processing means specific to the corresponding communication paths 1 to 3, respectively, and perform communication protocol processing for communicating with the communication destination. The gateway device 10 includes a storage unit 110, and stores an air conditioner management table 111 for managing the air conditioner 40 at the end of communication path 1. The air conditioner management table 111 is a management table that associates the identifier in communication path 1 for each air conditioner 40 with the identifier for each air conditioner 40 in the communication standard in communication paths 2 and 3. The air conditioner management table 111 may be set by the installer when setting up the gateway device 10, or the identifier of communication path 1 may be used as is. The air conditioner management table 111 may also be generated by converting the identifier of communication path 1 based on a conversion rule.

The memory unit 110 also stores GW information 112, such as identifier information of the gateway device 10, which is required when communicating with the cloud server 20, and cloud server information 113, such as the address of the cloud server 20 to be communicated with and secret information such as an encryption key for secure communication.

The delivery processing unit 104 can communicate with the air conditioner 40, the cloud server 20, and the air conditioner operation terminal 30 using the communication units 101 to 103, respectively. The delivery processing unit 104 performs delivery processing by determining whether to deliver the air conditioner control command received from the air conditioner operation terminal 30 to the air conditioner 40 or the cloud server 20. The delivery processing unit 104 also delivers the control target value of the air conditioner 40 received from the cloud server 20 to the air conditioner 40 via the air conditioning controller 105.

In addition, when the delivery processing unit 104 is able to communicate with the cloud server 20, it delivers the air conditioner control command received from the air conditioning operation terminal 30 to the cloud server 20.

In addition, when communication with the cloud server 20 is not possible, the delivery processing unit 104 delivers the air conditioner control command received from the air conditioner operation terminal 30 to the air conditioner 40.

The air conditioning controller 105 controls each of the multiple air conditioners 40 individually.

In addition, the gateway device 10 operates in either a cloud priority mode, which prioritizes control by the cloud server 20, or a local priority mode, which prioritizes control by the air conditioning operation terminal 30.

Figure 3 is a functional configuration diagram of the cloud server 20 in the first embodiment. The cloud server 20 has a communication unit 201 for communicating with the gateway device 10 via the communication path 2. For communication on the communication path 2 between the gateway device 10 and the cloud server 20, Internet communication such as TCP/IP communication, HTTP/HTTPS, and UDP/IP communication is used. The communication unit 201 has communication processing means required for the communication method used to communicate with the gateway device 10. Note that multiple air conditioning control systems S may be configured by communicating with multiple gateway devices 10 via the communication path 2. In this case, each gateway device 10 is identified by an identifier.

The storage unit 202 stores gateway information, management information for the air conditioner 40, and various air conditioner status information required for air conditioning control for each identifier of the gateway device 10. In addition to the latest status value, the air conditioner status information may also store past information as time series data with date and time information. Furthermore, the storage unit 202 stores air conditioning setting change request information transferred from the air conditioning operation terminal 30 via the gateway device 10 as history data together with date and time information. The air conditioning setting change request information includes information such as the identifier of the target air conditioner 40 and the parameters (target values) of the change request. The storage unit 202 may store weather information acquired by the weather information acquisition processing unit 206. The weather information acquisition processing unit 206 has a means for acquiring weather information and weather forecast information from a weather information providing service via the Internet.

The remote setting processing unit 203 stores the control command for the air conditioner 40 received from the gateway device 10 in the memory unit 202 as history data. Specifically, for example, the remote setting processing unit 203 passes each piece of information received from the communication unit 201 to the memory unit 202 and stores it. Furthermore, if the received request is information requesting a change to air conditioning settings, the remote setting processing unit 203 passes it to the determination unit 204.

The determination unit 204 passes the air conditioning setting change request information (air conditioner control command) received from the remote setting processing unit 203 to the decision processing unit 205, and passes the latest air conditioner control target value received from the decision processing unit 205 to the remote setting processing unit 203 to send to the gateway device 10.

The decision processing unit 205 decides the control target value of the air conditioner 40 based on the air conditioner control command received from the gateway device 10. Specifically, for example, the decision processing unit 205 decides the control target value of the air conditioner 40 based on the air conditioner model information, air conditioner status information, building space model information, space status information, setting change history data, weather information, etc. stored in the memory unit 202.

The determination processing unit 205 corrects the air conditioner control target value determined based on the air conditioner control command received from the gateway device 10 based on the air conditioner control target value corresponding to the air conditioner control command in the history data stored in the storage unit 202, which is at least related to either PMV (Predicted Mean Vote) control or energy saving control. In other words, a comfort index PMV is calculated as an index for quantifying the comfortable air conditioning conditions for people, and an air conditioning setting temperature that keeps this PMV constant is calculated as needed using a model-based air conditioning control method. Furthermore, a method of simulating the transition of room temperature from a space heat balance model and an air conditioning model may also be used. The determination processing unit 205 periodically calculates the control target value for the air conditioner 40. The determination unit 204 determines that the target value has changed from the previous calculation value, and transmits a request to change the setting of the control target value to the air conditioner 40 via the remote setting processing unit 203.

The air conditioner control target value is, for example, a temperature setting value. When the decision processing unit 205 receives a temperature setting change request value from the air conditioning operation terminal 30 via the gateway device 10, the decision processing unit 205 may use the temperature setting change request value for a predetermined time (e.g., 15 minutes), and use the corrected air conditioner control target value after the predetermined time has elapsed.

In addition, when the decision processing unit 205 receives the same temperature setting change request value two or more times from the air conditioning operation terminal 30 via the gateway device 10, the decision processing unit 205 may increase the specified time the more times the same temperature setting change request value is received.

In addition, when the decision processing unit 205 receives the same temperature setting change request value two or more times from the air conditioning operation terminal 30 via the gateway device 10, the more times the same temperature setting change request value is received, the smaller the correction range of the corrected air conditioner control target value may be.

Figure 4 is a functional configuration diagram of the air conditioning operation terminal 30 in the first embodiment. The air conditioning operation terminal 30 is capable of communicating with the gateway device 10 via the communication path 3, and is equipped with a communication unit 301 that performs communication processing. For example, the communication may be the BACnet method that is widely used in building facility networks, or a communication method specific to the air conditioner. The user operates the air conditioner 40 via the operation unit 303.

The operation processing unit 302 issues a setting change request to the air conditioner 40 and sends it to the gateway device 10 via the communication unit 301. As a result, a response is returned from the gateway device 10, and the operation processing unit 302 receives it and issues a command to the display processing unit 304 to display the operation result. The display processing unit 304 reflects the result on the display via the display unit 305. The display unit 305 may be a display device, or may be a simple liquid crystal display or an LED (Light Emitting Diode) lamp display. The display may be any of characters, icons, changes in display color, etc.

The display processing unit 304 also causes the display unit 305 to display either the cloud priority mode or the local priority mode as the current mode information acquired from the gateway device 10.

The communication unit 301 also transmits information on either the cloud priority mode or the local priority mode selected by the user using the operation unit 303 to the gateway device 10.

Figure 5 is a sequence diagram of the basic operation of the air conditioning control system S of the first embodiment. As a result of a user operating the air conditioning operation terminal 30, a setting change request for the air conditioner 40 is issued and transmitted to the gateway device 10 via communication path 3 (S11, (1) in Figure 1). Having received the request, the gateway device 10 transmits the request to the cloud server 20 via communication path 2 by the delivery processing unit 104 (S12, (2) in Figure 1).

The cloud server 20 that receives the request performs the above-mentioned process internally ((3) in FIG. 1), calculates the control target values for the air conditioner 40 that take comfort and energy saving into consideration, and returns a modification request to the gateway device 10 (S13, (4) in FIG. 1). The delivery processing unit 104 of the gateway device 10 sends the received modification request to the air conditioner 40 that is the target of the configuration (S14, (5) in FIG. 1).

When the air conditioner 40 that received the request returns a response (S15), the gateway device 10 temporarily transmits the response to the cloud server 20 (S16). The judgment unit 204 in the cloud server 20 judges, for each type of response, whether to return the response returned from the air conditioner 40 as is to the air conditioning operation terminal 30, or to modify the response to a value that does not cause a contradiction with the response expected for the original request before modification. If the judgment unit 204 determines that modification is necessary, it modifies the response and passes it to the gateway device 10 (S17). The gateway device 10 returns the response passed from the cloud server 20 to the air conditioning operation terminal 30 (S18). The air conditioning operation terminal 30 reflects the response in the display on the display screen.

Figure 6 is a sequence diagram of the air conditioning control system S of the first embodiment when a cloud communication error occurs. The air conditioning operation terminal 30 sends a setting change request to the gateway device 10 (S21). When the gateway device 10 receives the request, if the communication path 2 is interrupted or a communication error occurs for some reason when sending request information to the cloud server 20 or when the cloud server 20 returns a modified request (S22, S23), the gateway device 10 sends the request received from the air conditioning operation terminal 30 to the air conditioner 40 via the communication path 1 (S24). In addition, the gateway device 10 receives a response from the air conditioner 40 (S25) and returns the response to the air conditioning operation terminal 30 without sending it to the cloud server 20 (S26). With this method, the operation of the air conditioning control system S can be maintained even if the gateway device 10 cannot communicate with the cloud server 20.

Figure 7 is a sequence diagram when a fake response is used by the air conditioning control system S of the first embodiment. The air conditioning operation terminal 30 sends a setting change request to the gateway device 10 (S31). The gateway device 10 sends the request to the cloud server 20 (S32).

Next, the cloud server 20 returns the modification request and the response to be returned to the paired air conditioning operation terminal 30 to the gateway device 10 (S33). The delivery processing unit 104 of the gateway device 10 returns the response to the air conditioning operation terminal 30 (S34). The gateway device 10 sends the modification request to the corresponding air conditioner 40 (S35), and communicates the response (S36) returned from the air conditioner 40 to the cloud server 20 (S37), but does not communicate it to the air conditioning operation terminal 30. This enables the air conditioning operation terminal 30 to return a response without contradiction. For example, if the request in S31 was for 25°C and the modification request in S33 was for 27°C, the response in S34 will be a response of 25°C.

Next, FIG. 8 is a sequence diagram when a pass-through response is used by the air conditioning control system S of the first embodiment. Here, an example of a sequence is described in which the response returned from the air conditioner 40 is returned to the air conditioning operation terminal 30 as is, without being modified by the cloud server 20.

The air conditioning operation terminal 30 sends a setting change request to the gateway device 10 (S41). The gateway device 10 sends the request to the cloud server 20 (S42).

Next, the cloud server 20 returns the modification request to the gateway device 10 (S43). The delivery processing unit 104 of the gateway device 10 sends the modification request to the corresponding air conditioner 40 (S44), and communicates the response returned from the air conditioner 40 (S45) to the cloud server 20 (S46), and also to the air conditioning operation terminal 30 (S47). This has the advantage that the actual information of the air conditioner 40 is returned as is to the air conditioning operation terminal 30, so there is no discrepancy between the actual state of the air conditioner 40 and the display on the air conditioning operation terminal 30. For example, if the request in S41 is for 25°C and the modification request in S43 is for 27°C, the response in S47 will be a response of 27°C.

Regarding response handling, the three methods described in Figures 6 to 8 may be used depending on the type of request.

In this way, according to the first embodiment of the air conditioning control system S, the gateway device 10 communicates with the cloud server 20, the air conditioning operation terminal 30, and the air conditioner 40 as described above, so that air conditioning control can be continued while using the cloud server 20 even if a communication failure occurs between the cloud server 20 and the air conditioner 40 (communication path 2).

For example, if the gateway device 10 can communicate with the cloud server 20, it delivers the air conditioner control command received from the air conditioning operation terminal 30 to the cloud server 20. Also, if the gateway device 10 cannot communicate with the cloud server 20, it delivers the air conditioner control command received from the air conditioning operation terminal 30 to the air conditioner 40.

In addition, the cloud server 20 stores historical data on the PMV control and energy saving control of the air conditioner control commands, allowing it to accurately correct the air conditioner control target values. In other words, it is possible to create air conditioner models and space models that are more suited to the actual environment from past air conditioner operation performance data accumulated on the cloud server 20, and further use real-time information on weather information and users, and future prediction information to perform highly accurate air conditioning control.

Note that there are prior art model-based air conditioning control systems that use PMV, but these systems have problems in that temperature settings made on the air conditioning controllers (remote controls) in the building are not accepted or are constantly overwritten and not reflected in the air conditioning control. In other words, changes to temperature settings made by users on the air conditioning operation terminals in the building are ignored, which reduces user satisfaction and causes problems. On the other hand, according to the first embodiment, temperature settings made on the air conditioning operation terminal 30 can also be flexibly reflected, so such problems do not arise.

In addition, when the cloud server 20 receives a temperature setting change request value from the air conditioning operation terminal 30, the cloud server 20 may use the temperature setting change request value for a predetermined time (e.g., 15 minutes), and use the corrected air conditioner control target value after the predetermined time has elapsed. This can improve user satisfaction.

In addition, when the cloud server 20 receives the same temperature setting change request value two or more times from the air conditioning operation terminal 30, the cloud server 20 may increase the predetermined time the more times the same temperature setting change request value is received. This reduces the possibility of dissatisfaction among users who make the same temperature setting change request value two or more times on the air conditioning operation terminal 30.

Furthermore, when the cloud server 20 receives the same temperature setting change request value from the air conditioning operation terminal 30 two or more times, the more times the same temperature setting change request value is received, the smaller the correction range of the corrected air conditioner control target value may be. For example, if the first request is 25°C and the corresponding corrected target value is 27°C, and if the second request is the same 25°C, the corresponding corrected target value is set to 26.5°C. Furthermore, if the third request is the same 25°C, the corresponding corrected target value is set to 26°C. In this way, the corrected air conditioner control target value is gradually brought closer to the temperature setting change request value based on the user's request, thereby reducing the possibility of the user becoming dissatisfied.

In addition, by providing cloud priority mode and local priority mode as air conditioning control modes and making them selectable and displayable on the air conditioning operation terminal 30, convenience for users is improved.

Furthermore, by acquiring feedback information from user operations and reflecting and correcting it in the calculation of air conditioner control target values without changing the air conditioning operation terminal 30 used in existing products or the communication standard between the air conditioning operation terminal 30 and the air conditioning controller 105, it is possible to achieve more satisfying and comfortable air conditioning. And because there is no need to change the communication standard between the air conditioning operation terminal 30 and the air conditioning controller 105, a further advantage is that it can be applied to air conditioning systems using existing products.

Second Embodiment
Next, a second embodiment will be described. Regarding matters similar to those in the first embodiment, duplicated explanations will be omitted as appropriate. Fig. 9 is an overall configuration diagram of an air conditioning control system S of the second embodiment.

The gateway device 10 can control each air conditioner 40 via the air conditioning controller 41. The control flow is in the order of (1) → (2) → (3) → (4) → (15) → (16).

In this way, according to the second embodiment, in addition to the effects of the first embodiment, the following effects are achieved. In other words, if the air conditioner 40 and the air conditioning controller 41 are already installed, the gateway device 10 and the cloud server 20 can be applied without changing their communication protocols, etc., so that the effort and cost of implementation can be reduced.

The air conditioning control method, in which, when a temperature setting change request value is received from the air conditioning operation terminal via the gateway device, the decision processing step uses the temperature setting change request value for a predetermined time, and uses the corrected air conditioner control target value after the predetermined time has elapsed . An air conditioning control method using an air conditioning control system including an air conditioner, a gateway device that communicates with an air conditioning operation terminal for operating the air conditioner, and a cloud server that communicates with the gateway device,
the gateway device determines whether to deliver the air conditioner control command received from the air conditioner operation terminal to the air conditioner or to the cloud server, and performs delivery processing;
The cloud server performs a determination process step of determining an air conditioner control target value based on the air conditioner control command received from the gateway device,
The gateway device delivers the air conditioner control target value received from the cloud server to the air conditioner,
The cloud server includes:
A storage unit for storing information is provided,
A remote setting process step is performed in which the air conditioner control command received from the gateway device is stored in the storage unit as history data;
a determination is further made as to whether the air conditioner control command stored in the storage unit is passed to the determination processing step, and whether the air conditioner control target value received from the determination processing step is passed to the remote setting processing step in order to be sent to the gateway device;
The determination process step corrects the air conditioner control target value determined based on the air conditioner control command received from the gateway device based on the air conditioner control target value corresponding to the air conditioner control command in the history data stored in the storage unit, the history data relating to at least one of PMV (Predicted Mean Vote) control and energy saving control,
The air conditioner control target value is a temperature setting value,
In the determination processing step, when the same temperature setting change request value is received two or more times from the air conditioning operation terminal via the gateway device, the correction range of the corrected air conditioner control target value is made smaller the more times the same temperature setting change request value is received .
